Titelphoto New Porsche Museum in Stuttgart, Dr.-Ing. hc F. Porsche AG Netherland’s highest residential tower block, 158 metres in height, is being constructed in Rotterdam. The 45-storey building is named “New Orleans” and has been designed by the Portuguese architect Alvaro Siza. Official completion date is in 2010. Around 20,000 fischer nail anchors FNA II 6 x 30/75 A4 were used for fixing the frame constructions of the aluminium facade windows and the sliding doors of the loggias. The anchor was chosen because of its small drill hole diameter and its rapid installation. 4,100 short FNA II 6 x 30/5 A4 hold the side sections of the frames in the loggias in the concrete. Sliding doors the height of the floor are installed into the loggias in the west and east façade. To absorb the high wind pressure forces, the frames are fixed directly to the concrete floor above using a total of 6,500 SXS 10 x 120 A4. The lower frames are anchored in the concrete with around 3,400 anchor bolts FAZ II M12/10 A4. Also, over 4,250 hammerset anchors EA M16 x 65 were used for temporary fixings, around 20,000 nail anchors for various applications, and the Upat EXA and the injection mortar FIS V 360 S were used in the building. Photo: VESTEDA, Groep bv, Maastricht Fixing technology Al Hamra skyscraper in Kuwait The Al Hamra skyscraper is expected to be Kuwait’s tallest building at 412.5 m (1350 ft) when it is completed in 2010. It will have 75 storeys dedicated to offices. The installation of the stone façade started in summer 2009. The façade of the tower will be made from a combination of glass-aluminium windows, natural stone and Jura marble from JMS of Germany. When finished the Al Hamra will be the highest stone-clad building in the world. The façade elements were prefabricated in China by Wuhan Lingyun Building Decoration Engineering Co. Ltd, and shipped to Kuwait. The stones are attached to the pre fabricated elements with approximately 100,000 fischer FZP anchors for limestone. The designer, Skidmore, Owings and Merrill (S.O.M.), of New York, USA, the general contractor Ahmadiah Contracting & Trading Co. of Kuwait, and the façade consultant Arup of Hong Kong, decided to work with FZP anchors from fischer following an intensive two-day presentation on the features and benefits of the product. Photo: PERI GmbH, Weißenhorn 2 37 CONTENT Meeting technical challenges > The new Porsche Museum in Stuttgart sets truly amazing standards in structural engineering and in architecture – which could hardly have been accomplished without innovative products supplied by fischer. Besides many others, one of the challenges meant fixing a glass façade inclined outwards. For the first time, overhead glazing inclined by 16.5° from the vertical was attached to the substructure with fischer FZP-G undercut anchors. Once the failure load tests had been completed successfully, the bold and innovative design was given a one-off approval. But the fischer undercut anchor is not only demonstrating its unique potential in glass: it has also proved to be the best and most con vincing solution for fixing into natural stonework in New York’s tallest residential building. Meanwhile the new importance of chemical fixings has now been demonstrated impressively by a number of unusual applications at home and abroad. These include technically sophisticated con structions such as the City Tunnel in Malmö in Sweden, as well as by alpine mountaineers and climbers who entrust their lives to safe metal anchorings in rock using fischer injection resin. This issue of connect it also includes features on our national company in France and on SFS unimarket, our successful distribution partner in Switzerland. Their local activities always give you the best of service. fischer wouldn’t be fischer if – complying with our mission statement – we didn’t regularly enrich the market with new and economical products for our customers’ benefit. Since the summer of 2009, our new range of timber screws has defined new standards in woodworking. The fischer Power-Fast range is extremely easy and convenient to use and is unbeatable for speed of installation. But read for yourself and be inspired by fischer. I hope you’ll find this issue interesting and enjoyable reading.

Porsche AG Dr. Roland Unterweger, Advanced Curtain Wall Technique The outer secondary façade is a glass fitting mounted construction using fischer FZP-G PORSCHE MUSEUM > The opening ceremony for the new Porsche-Museum in Stuttgart was held at the end of January 2009. The design by the Viennese architects Delugan Meissl impresses with its array of different geometric shapes which largely do without right angles. The glass façade, inclining outwards and held in place with unique fischer undercut anchors, faces Porsche Square. The monumental and futuristic building touches the limits of structural design and sets a new architectural highlight in Stuttgart’s cityscape. Built in Stuttgart-Zuffenhausen between the city metro station Neuwirtshaus, Schwieberdinger Strasse and Porsche Square, the Porsche-Museum stretched planners and contractors to their limits. The architects of Delugan Meissl aimed to create a space of sensuous experience which translates into architecture the dynamic nature and philosophy of the Porsche brand. The outcome is a steel, glass and sheet metal giant weighing 35,000 tonnes, with a 5,600 square metre exhibition space. Floors, ceilings and walls are finished in sober white. Alternating displays of 80 unique vehicles and 200 other small exhibits show Porsche’s impressive history. The museum also houses the company archive, a garage for veteran cars, which is also for the use of private clients, a conference area and a variety of catering establishments. Vertical section of the glass façade Structurally highly loaded steel concrete cores Structurally, the dynamically shaped monolithic building with a total length of 150 metres consists of the Basement and the Flier. The Basement with its three cores carrying the entire weight of the building consists mainly of waterimpermeable steel concrete. The cores with their base plates 3.75 metres in thickness rest on large-size piles with a diameter of 1.20 metres. Due to the exceptional weight and geometry of the structure, its walls are up to 75 cm thick in places. The actual exhibition area is located above the Basement. A complex load-bearing steel structure, with spans of as much as 60 metres and overhangs of as much as 45 metres, rises above a height of 16 metres. Part of the exceptional weight is primarily carried by a circumferential trussed beam with the height of a floor, before the weight is transferred to the ground through the three cores. The glazed front of the building offers a panoramic view of Porsche Square. The other façades are clad in a white sheet metal skin. The exhibition hall itself also acts as a roof over the entrance lobby. Detail vertical section of the glass façade 5 6 of triangular hollow profile locking elements, stiffened with vertical flat steel posts. The glass fixing system used For the first time worldwide, the undercut technology alloweda fixing to be used for glass where the bore hole does not pierce the glass. The glass fixing is installed via a conically undercut blind hole with torque control. This allows glass panes to be anchored to the substructure without any fixings visible from the outside. The smooth outside is aesthetically more pleasing, there are no breaks in the glass to allow penetration of moisture or dirt, and the façade stays cleaner for longer periods. fischer undercut glass fitting FZP-G-Z for laminated safety glass A challenge for the glass construction The front façade proved to be a particularly demanding challenge. It is mounted above the main entrance and has been designed as a double façade. The inner insulation glass façade rests on line-shaped bearings all round and forms the actual space closure. The outer, secondary façade was made as a construction with point-to-point in-place fittings. The space between the façades is acces sible for cleaning and service work, with the service per sonnel moving across mobile ladders and equipped with safety ropes. The façade is inclined by 16.5° from the vertical to the outside and is about 13 metres in height. Its dimensions at the upper edge are 41 metres and 40 metres at the lower edge. The lower edge of the façade is 14 metres, the upper edge 27 metres above the top edge of the build ing. As a result of this angle, the façade is actually an overhead glazing, according to building laws. The glass joints between the panels were left open. The fischer FZP-G-Z undercut glass fitting has the general construction authority approval (No. Z-70.2-122) of the Deutsche Institut für Bautechnik (DIBt). The approval is valid for glass panes with a maximum size of 2,000 mm by 3,000 mm. They may be used for rear-ventilated out side claddings under DIN 18516-41 and for roomenclosing vertical glazing, with tempered glass (ESG or ESG-H) and laminated safety glass (VSG). The glass panels can be enamelled or coated, and they may be used as carriers for top-laminated solar panels. Successful failure load and residual load-bearing capacity tests The overhead glazing used is subject to special technical rules and regulations for line bearing glazing (TRLV) and the technical rules and regulations for the design and execution of point bearing glazing (TRPV). The focus of these safety considerations is on the residual load-bearing capacity of the glazing in the failure state. The fischer FZP-G-Z glass fittings conform with the appro val. However, the type of glass used (VSG from TVG), the glass size and the method of installation are not regulated For this point-held glazing made of laminated safety glass (VSG), the outside consists of 10 mm heatstrengthened glass (TVG), the inside of 8 mm TVG. The individual panes have a maximum width of 3.454 mm and a height of 1.917 mm, each resting at the upper and lower edge of the glass on six fischer FZP-G-Z undercut glass fixings. The edge spacing to the glass edges is only 85 mm. The dead weight of the construction is absorbed by two steel angle elements. The undercut glass fixings are mountedon to the substructure with steel lugs with large bores to ensure stress-free support for the glazing. The substructure made of S 235 construction steel consists Test stand to check the residual load-bearing capacity PORSCHE MUSEUM Installing the glass façade in the approval. For this reason, the owner applied to the supreme building authority for consent in individual cases, based on an arithmetical feasibility study and the test concept by SuP Ingenieure GmbH of Darmstadt which had been coordinated with the supreme Land building authority. Proof of the load-bearing capacity was determined by means of failure load test. For this purpose, the façade builders Rupert App of Leutkirch carried out tests at their headquarters in the Allgäu under supervision of the State Material Test Institute (MPA Darmstadt) and the Land building authority of Baden Württemberg. The testing regime to establish the maximum load required a hori zontal installation position and loading the glass façade with sandbags. These tests resulted in an adequate minimum safety level of γ = 4.30. To evaluate the residual load-bearing capacity, the Darmstadt Material Testing Institute carried out the appropriate tests. For the tests, building components were examined in their original installed position at an inclination of 16.5° from the vertical. In line with the test concept, half the wind load was applied on to the test elements by using sandbags. The laminated safety glass panes were then struck at different points inside and out with a pick hammer and destroyed as scheduled. The panes broke into pieces with a breakage picture typical for heatstrengthened glass. No significant deformation was found even after putting the panes under stress in as many as eight different points. The condition for a successful test: no failure after 24 hours under simulated reduced wind load and dead weight. The simulated wind load was then removed and the construction assessed. No significant changes from the initial situation were found. The construction was then observed for another period of 24 hours, again without any changes worth mentioning from the initial situation. The specifications by the Land authorities were fully complied with. Based on the positive test results and the final expert report given by SuP Ingenieure GmbH, the single-instance approval was finally granted. Summary The Porsche-Museum goes to new dimensions of struc tural engineering. This is also true of the unusual design of the glass panorama façade which is absolutely unique in its present form. The project has been made possible by the close and constructive collaboration between owners, planners, test institutes, experts, building authorities, façade builders and the façade expertise of the fischer group of companies. 7 8 FHB II also suitable for low strength concrete C 12/15 Anchors for rolled concrete Günter Seibold and Geza Harangozo, Technical Support, fischer Germany Expert reports are available for anchoring the FHB II in low-strength concrete C 12/15 (B 15) > Today the bed-plates of warehouses or production sheds are often made with rolled concrete. When it comes to anchoring high-rise shelving units or conveyor systems, the question is often asked if rolled concrete is suitable. For cases such as these, fischer offers its Highbond Anchor FHB II and the Anchor Bolt FAZ II Rolled concrete is usually spread in earth-moist condition using conventional road finishers or front wheel loaders, levelled with the help of laser technology, and finally compacted with smooth rollers or – more rarely – with vibration rollers. The advantages of rolled concrete are its high economic efficiency, its early loading capacity, high resistance to chemical and physical stress, and the large area which can be made in a single day. Between 1,500 m² and 2,000 m² per day are feasible. Rolled concrete is usually spread in a thickness of between 18 cm and 25 cm. If used as industrial or shed flooring, it is usually top coated with a special synthetic layer with a thickness of about 2 cm. Although rolled concrete has a very low water-cement ratio and features no reinforcements, shrinkage cracks are unavoidable, particularly in the lift joints where shrinkage cracks must be expected. For this reason, only anchors suitable for cracked concrete should be used in rolled concrete. This view is also shared by the Institute for Façade and Fixing Engineering (IFBT) which, owing to the charac teristics of rolled concrete, assigns it to the DIN 1045 building material class and recommends using anchors and fixings suitable for cracked concrete. The load capa cities of the anchors depend on the strength of the rolled concrete and are similar to those of comparable standard concrete strengths. If the concrete strength of the rolled concrete bed-plate is unknown, grade C 12/15 (B 15) should be taken to be on the safe side. From fischer’s extensive range of fixings and anchors, it is especially the Highbond FHB II resin anchor and the fischer FAZ II anchor bolt which are suitable for rolled concrete. Both product families have the general construction approval for concrete strengths of C 20/25 (B 25) and higher. For the FHB II there are additional expert reports concerning anchorings in low-strength concrete C 12/15 (B 15). When selecting the right effective length of the anchor, it should be kept in mind that the anchor and its effective length may have to bridge a non-load-bearing screed or top layer. Proof of the local introduction of the anchor load into the bed-plate is made by applying the anchor design method. As there are no reinforcements, separate confirmation tests must be made for the forces transmitted into the bed-plate by the anchors. Fixing technology FAZ II and FHB II are suitable for anchoring high-rise shelving units 9 10 European CEN Standard Design of anchoring for fixings in concrete Photo: Klas Andersson Dr. Rainer Mallée, Technology Transfer and Research The new CEN standard combines the guidelines ETAG 001, Annex C, and the Technical Report TR 029 and is a very helpful tool for designing subsequently set fixings > The last 30 years have seen some intensive basic research in the field of fastening engineering. The interest focused on investigations involving the load-bearing capacity of anchors and on the most important parameters influencing their performance. The increase in knowledge enlarged the range of appli cations of anchors to a substantial degree and resulted in a continuous improvement in the design methods. While the first German approvals initially permitted only single anchors and after 1978 also pairs of anchors, the introduction of the kappa method in 1983 allowed for the first time the design and implementation of groups with as many as four anchors and with any axial spacing and edge distances. As the level of knowledge was still relatively limited at that time, the method necessarily led to conservative design results. A clear improvement was brought about by the so-called CC Method which was first launched in 1993 in Germany as design guideline by the German Institute for Construction Engineering (DIBt) and in 1998 in Europe as ETAG 001, Annex C “Design Methods for Fastenings”. The last milestone in the series of design methods is the EOTA Technical Report TR 029 “Design of Bonded Fastenings” which accounts for the particularities of bonded resin anchors. In order to standardise the design of fastenings in Europe and to put these on a common basis, the obvious course Fixing technology of action was to combine the existing design guidelines in a European CEN standard and so to make the practice and the state of the art in engineering accessible in a single document. Also, the regulations should not only address fixings, but cast-in-place components such as headed studs and anchor channels. In October 2000, the constituent meeting of the standard committee CEN/TC 250/SC 2/WG2 “Design of Fastenings for Use in Concrete” convened in Stuttgart with members from nine European countries. Once the consultations had been completed in 2008 and following the formal European voting procedure, the document was published in 2009 as part of the Eurocode (prCEN/TS 1992-4-1 through 5). Since August 2009, the standard has also been available in German under the title “Bemessung der Verankerung von Befestigungen in Beton” (DIN CEN/ TS 1992-4-1 through 5) from Beuth publishing house. The letters “TS” stand for “Technical Specification” which is a pre-standard comparable with the Yellow Paper of a German standard and which may be used without any restriction as state of the art engineering practice once it has been introduced on a national level. Standard in five sections The distribution of the shear forces and torsion moments depends on the mode of failure and the edge distance. component acting perpendicular to the edge of the building member is absorbed only by the fastening set close to the edge, while the shear load component parallel to the edge is distributed over all the fastenings. Shear load components directed away from the edge can be neglected in the proof of concrete edge failure. For all other modes of failure it is assumed that all the fastenings of the group take up shear forces, regardless of edge distance. The standard includes the sections “General”, “Headed Bolts”, “Anchor Channels”, “Fastening – Mechanical Systems” and “Fastenings – Chemical Systems”, with the last two sections applying only for fastenings with a European technical approval (ETA). It regulates applications which fall under EN 1992. For fastenings involving special requirements (e.g. nuclear power stations or civil defence constructions), some supplements may be necessary. Also, the document addresses fastenings under predominantly static and predominantly non-static loads and fastenings exposed to seismic loads. As no European approval guide lines have so far been worked out for the last two load types and since no fastenings with ETA exist as a result, these sections of the standard can currently not be applied. Details on the durability of the fastening elements and on design under fire exposure are also given. In the proof of the load capacity, the design value of the impact effects must not be greater than the design value of the resistance. This proof must be made under tension load for the modes of failure steel fracture, conical concrete breakout, pull-out/pull-through and splitting of the concrete, and under shear load for steel fracture, concrete edge failure and concrete pry-out failure. For chemical fastenings, proof against pull-out/pull-through is replaced by the proof against combined pull-out and concrete breakout failure. The calculation approaches for resistance values essentially correspond to those in ETAG 001 Annex C and TR 029, with a few minor differences at some points. The standard defines the design of single anchors and of groups of as many as eight fastenings. Unlike the previous guidelines, the strength range of the concrete is enlarged to include the strength classes C12/15 to C90/105, provided the fastenings are approved for these strengths. The CEN standard “Design of Fastenings for Use in Concrete” has now created design regulations which combine the tried and tested guidelines of ETAG 001, Annex C and of the Technical Report TR 029 into a single document, which also assesses subsequently set fastenings (anchors) and cast-in-place components (headed studs, anchor channels) according to the same principles. This gives the design engineers a valuable tool for the safe and economical design of fastenings. The distribution of the standard forces and bending moments acting on the individual fastenings of a group is made in accordance with the theory of elasticity, with the theory of plasticity also allowed for the computation under certain circumstances. The distribution of the shear forces and torsion moments depends on the mode of failure and the edge distance. For fastenings close to the edge and with proof against concrete edge failure, the shear load Valuable tool 11 12 EWI – External Wall Insulation Anchoring external thermal insulation composite systems Dr. Klaus Fockenberg, PR Officer, fixing systems Andreas Duesberg, Product Manager, E.W.I. Setting of EWI > Almost every other residential building in Western Europe is between 30 and 60 years old and therefore will be in need of modernisation in the foreseeable future. In terms of ongoing and future energy modernisation programs, external thermal insulation composite systems (ETICS) are particularly important for insulating outside walls. The systems are capable of lowering heating energy consumption by as much as 50 percent. Fundamentally, there are several types of ETICS with approvals in which the use of anchors and fixings is also regulated. These include bonded/anchored and mechanical systems. For bonded and anchored systems, the insulating boards are first glued or bonded to the outside wall and then fixed with anchors. Depending on the fixing system, the plates of the fixings are either flush with the outer surface of the insulating board or are sunk to a PRODUCTS Termoz CN is made of glas fibre reinforced plastic with a metal top. specified length into the insulation and covered by a round plug made of the same insulating material. In mechanical systems, the insulating boards of ETICS are fixed to the outside walls, for instance with metal mounting straps. These mounting straps are anchored into the load substrate using anchors with European Technical Approvals. Anchor fixings are safer and more economical Bonded systems can be used if the substrate is suitable for transmitting the dead load of the bonded system into the building material of the wall via shear forces. Facades are usually exposed to many different weather conditions over long periods of time. Depending on local conditions, dirt deposits, paintwork and different types of plaster and rendering can substantially reduce the adhesion of the bonding agent. Also, coatings and layers of paint can cause unexpected reactions with the bonding agents in the course of time. This phenomenon is known in practice as saponification or embrittlement and can in due course substantially reduce the load-bearing capacity of the system and cause severe damage to the building. Besides providing higher levels of safety, anchoring the insulation boards also offers advantages in terms of money. In many cases, the time-consuming and expensive preparation of the substrate is unnecessary. Approved ETICS fixings are easy to process, because only loose and flaking coats need to be removed before old facades are repaired. Highly absorbent and chalky coatings should be treated with in-depth primer. Termoz 8 UZ screw fixing with anchor plate 140 High quality plate fixings mounted through the insulation generate additional contact pressure through their rigid anchor plate and support the permanent friction lock effect between bonding agent and base. The retention power in the base clamps the insulation material through sufficient contact pressure, an effect which substantially reduces the risk of damage to the building. This applies both to plates mounted flush with the surface of the insulation material and to sunken plates. The precondition is a powerful anchoring of the expansion zone in the building material of the wall and an adequate stiffness of the plate. Both these factors are regulated in the approval (European Technical Approval; ETA). Another important function of the anchoring is the transfer of the wind suction loads. The tension load acting through it on the facade can exert substantial stress on the bond. Depending on wind load zone, terrain category and building height, different wind suction loads must be taken into account. In cases such as these, approved plate anchors also provide higher degrees of safety because they take up the tension stress through their plates and the expansion elements (nail/screw) and transmit the stress into the substrate. 60 mm plate diameters sufficient in most cases The fixings used in ETICS are set using the through-fixing method, with the fixture (insulating material or metal mounting straps) drilled through with the same diameter as the base or substrate. The fixing is then pushed The anchor plates for the Termoz PN are available in different colours. 13 14 Termoz PN is made of glas fibre reinforced plastic. through the fixture into the drill hole and expanded. The maximum effective length is predefined by the ETICS anchor. In order to determine the required effective length, the thickness of the insulating material, the bond layer and any existing non-load-bearing coatings or layers (old rendering, insulation, etc.) must be taken into account. For anchoring underneath the fabric, a 60 mm anchor plate can also be used for compression resistant insulating materials such as polystyrene (PS) and HD mineral fibre boards. If more pliable insulating materials are used (rockwool of thermal conductivity category 035 or rockwool laminar boards), a larger plate is required, for instance fischer DT 90, 110, 140, which spreads the tension loads over a larger area. The typical fixings configurations are specified for anchoring underneath the fabric. thermal insulation effect. The fischer Termofix and Termoz anchors have a kp -value category of 0.00 – 0.002 W/K. In comparison, a 100 mm facade fixing with steel screw has a kp -value of 0.008 W/K. Fixings under ETA have an approval for certain classes and categories of building materials, known as categories of use. For individual building materials of these cate gories, the manufacturer has provided proof of the suitability of these fixings. If building materials not listed in the approval are encountered during work, the pull-out loads can be determined by means of pull-out tests on the actual object. The whole range of single components of a ETICS must be procured from the owner of the s ystem approval, otherwise the approval and the warranty will lapse. When used in ETICS, the thermal conductivity of the fixing is of ultimate importance. Ideally, the thermal conductivity of the fixing should differ only to a very small degree from that of the undisturbed insulating material in order to avoid thermal bridges. Thermal bridges rapidly dry out the rendering in the zone of the plate. With varying degrees of dirt deposits, these transient blemishes can become permanently visible. The fixing parameter playing a role here is the kp-value (point-sized thermal bridging influence) which, as a factor of the thickness of the insulating material and the number of fixings, can result in a drop in the fischer offers a wide range of products The Termoz 8 SV is the first ETICS screw fixing which needs no special tools Setting the screw of the Termoz 8 SV Under the ETA, the fischer group of companies offers a range of approved fixing systems for ETICS, among these various hammerset and screw fixings with different thermal insulation plates and washers. In detail, these include Termoz PN, Termoz 8 NZ, Termoz KS 8, Termoz 8 SV, Termoz UZ, Termofix CF, 6H and B. Also on offer are the Nail anchor N, the insulating material holder DHK, the insulating material fixing FID and the spaced installation system Thermax. produCtS COMPUFIX 8.3 More options for bonded anchors Dr. Rainer Mallée, Technology Transfer and Research > The EOTA Technical Report TR 029 “Design of Bonded Fastenings” provides new and better uses for this type of anchor. To ensure that these improvements can also be used in everyday work, it was necessary to make the appropriate changes to the COMPUFIX anchor design program. The upgrade also includes a new tool box (picture 1, lefthand margin of the input window) which allows the quick and easy selection of anchors and of anchor plates including the welded-on profile sections, and which also allows the user to determine the most important conditions of use. For users who are not, or not very, familiar with the layout of Windows Vista® or Windows 7®, the tool box makes it easier to run the program. Users of Windows Vista® or Windows 7® can now control all important functions with the large and user-friendly buttons of the “ribbon bar” which replaces the icon bar of the earlier Windows versions. The tool box in this version can be minimised by clicking the fixing needle in the top righthand corner of the box, which will enlarge the input field available for 3D drawings. With the publication of the Technical Report TR 029 it is now possible for the first time to design bonded anchors with variable embedment depth. This is probably the most important new feature because it allows the best possible utilisation of the fastenings. The anchoring or embedment depth in previous approvals for injectiontype anchors used to be constant and depended solely on the size of the anchor. Under tension load, in particular, changing from one anchor to the anchor with the next size up led to a sudden increase in the characteristic resistance values. In the worst case, the tensile load capacity of the smaller anchor was hardly sufficient and the anchor in the next size up was over-dimensioned. The only option for optimisation in groups of anchors was to use the anchor in the next size up and at the same time to reduce the axial spacings within the group and hence the resistance to conical concrete breakout failure (unless the size of the anchor plate had been specified). For steel failure and pull-out, this approach was ineffective because the load capacity for these modes of failure is not inf luenced by the axial spacing. The Technical Report TR 029, on the other hand, offers a variety of options for optimisation. For instance, the embedment depth of the smaller anchor can be enlarged until the characteristic resistance for the failure modes conical concrete break-out The REMOTEFIX® function allows user to exchange projects, screenshots and texts with partners 15 16 and combined failure through pull-out and concrete breakout is sufficient. The condition is that the resistance to steel failure is sufficiently great. If this is not the case, the larger anchor can be selected and its embedment depth can be adapted accordingly. To be able to use the advantage of a variable embedment depth, the appropriate input option had to be created. You will find the input field in the tool box (“Anchor selection” group) or in the “ribbon bar” on the tab with the same name. Clicking the input field will open a selection box (picture 2) which shows all permissible embedment depths for the selected anchor size (increments 1 mm). The value in brackets shows the associated maximum clamping thickness. Once the desired embedment depth has been selected, COMPUFIX automatically computes the design, allowing the user to read the result at once at the lower margin of the input window. The characteristic bonding tension of bonded anchors can depend on temperature, the category of use and the intensity of the drill hole cleaning. The temperature ranges are given in the appropriate approval (ETA). In the categories of use, a distinction is made between “dry and wet The tool box allows the quick and easy selection of the anchor concrete” and “dry and wet concrete and water-filled drill hole”, and with respect to drill hole cleaning, some approvals differentiate between “standard cleaning” and “premium cleaning”. As the selected mode of drill hole cleaning is of crucial importance for the load capacity of the anchor, COMPUFIX helps the setter and prints out the cleaning process on the page “Installation data”. Temperature, category of use and drill hole cleaning are selected in the tool box (“Anchor selection” group) or in the “ribbon bar” on the tab with the same name. With the Technical Report TR 029, the scope of validity of the design method used ETAG 001, Annex C, has now been enlarged to groups of eight anchors (picture 3). According to Annex C, groups with a maximum of six anchors were permitted. Also, groups of three or six anchors used to be allowed only if their edge distance c is c ≥ 10 · hef in all directions because the distribution of the shear loads over the individual anchors of this group could not be predicted with ultimate certainty owing to the usual hole clearance. In unfavourable cases, this can result in early failure in the event of concrete edge failure. This problem does not arise for large edge distances. Comparative computations have shown that groups of three produCtS and six anchors with edge distance of c ≥ 10 · hef under shear load will not fail through concrete edge break-out, but through steel fracture. According to TR 029 groups with 3, 6 and 8 anchors can also be arranged close to the edge (c ≥ cmin) if there are no shear loads. For shear loads, the edge distance of this group had to be c ≥ 10 · hef in all directions as before and an additional c ≥ 60 · d (hef = embedment depth of the anchor and d = diameter of the threaded rod). The second condition was necessary because the variable embedment depth allowed short and thick bonded anchors. Limiting the edge distance to multiples of the embedment depth alone would warrant no steel fracture in cases such as this. In designs in accordance with “fischer specification”, groups with 3, 6 and 8 anchors may also be arranged close to the edge (c ≥ cmin) if no shear loads act on the anchoring or if the annular gap between the anchor and the anchor plate is filled with pressure-proof injection mortar or bridged by some other means (e.g. metal sleeves). COMPUFIX automatically takes account of these conditions when the program reviews the minimum edge distance. Failure to observe this condition results in a detailed error message in the result window. Next to the above program upgrades, COMPUFIX 8.3 also includes the REMOTEFIX® function which allows users with internet connection to exchange projects, screen shots and texts with partners and to compare input data. Clicking the appropriate button on the “Start” tab in the “ribbon bar” (picture 4) will open a window which allows both partners to link their computers by entering the same four-digit number (“Session ID”). The partners can then transfer the content of their screens as screenshots, exchange comments and compare the input data of their examples. The compare function is a quick and easy way to show up any differences between their design examples. COMPUFIX 8.3 is compatible with the operating systems Windows 2000®, Windows XP® (32bit/64bit), Windows Vista® (32bit/64bit) and Windows 7®. The program allows users to construct and design safe and economical fastening quickly and with little effort. It offers you support in your everyday work. The new version is available free on CD or as download in the internet (www.fischer. de) and for users of older versions of COMPUFIX 8 also via LiveUpdate. The selection box shows all the permissible The scope of validity of the design method has been enlarged to include embedment depths of the selected anchor groups of eight anchors 17 18 A revolution in fixing technology Fast and comfortable fixings with fischer Power-Fast Shank ribs reduce the drive-in restistance considerably. The underhead cutting ribs provide for easy countersinking and a precise flush finish. Double thread reduces the splitting while the centre double thread provides un-braked drive. Cutting notches and the Power-Fast high performance wax effectively reduce friction. > The new screw range from the fischer group of companies of Waldachtal sets the benchmark for wood processing. These screws developed by fischer have an extremely high handling comfort and can be set quickly. Advantage: less effort, lower cost. fischer Power-Fast is a unique range of wood screw that packs the same level of innovation that the market has come to expect from the fischer brand. Power-Fast is a premium screw which delivers a vast number of user benefits, and with which fischer has set out to combine the features that were already good about screws and resolve the points which were not. The combination of distinctive design points has produced an effortlessly, quick to install screw which saves on time, money materials. The extra small screw point guarantees a fast ‚bite‘ as the screw can easily penetrate the wood at the first attempt and there is no need for a pilot hole even in hard wood. The head recess is designed with extra depth to reduce screwdriver ‚cam-out‘ and drive-in pressure which acts to prevent surface scratches and risk of possible injury. The double countersunk design is calculated to protect against the head twisting off, while the ribs underneath facilitate easier countersink and flush fitting of the screw Thread extending into the tip provides for the fast bite. into wood. When fastening metal fittings the ribs stop excessive turning when they come in contact with the metal. A double thread positioned at the screw tip and middle quickly removes drilling dust which helps prevent timber splitting, this opens up new construction possibilities as the screws can be set much closer to the edge than has previously been possible. Meanwhile the water-repellent fischer-branded packs can be opened in one of two ways, either as a chute from the front or from above, differentiating the fischer screw range from that of competitors. The packs also feature a large viewing window, so that the product can be seen externally, and they benefit from full product details printed on the pack. produCtS fischer FAZ II A4/C anchor bolt Stainless steel for demanding jobs > Minimum axial and edge spacings under extreme loads and in smaller component thicknesses in cracked concrete: these are the outstanding properties of the FAZ II anchor bolt, which is the best suitable for the tensile zone on the market. fischer now also presents the stainless steel version of the FAZ II A4/C. The FAZ II reaches up to 33 % higher tension loads than the best competitor products. It requires fewer fixing points, smaller anchor plates or fixings with lower dia meters. It can be used in extremely thin concrete members of just 80 mm in thickness. Users will also appreciate the good feeling when setting the FAZ II: a reduced number of hammer blows and just a few turns before the anchor “bites” and sits tight inside the drill hole. The geometry of the coated conical bolt and the design of the expansion clip (FAZ gvz in black, FAZ A4/C in stainless steel) guarantee an even load introduction and controlled expansion. These performance features save time and money during setting. The new FAZ II A4 anchor bolts made of stainless steel of corrosion resistance category III and FAZ II C made of highly corrosion-resistant steel grade (1.4529) replace the previous FAZ A4/C. They now complete the new generation of the FAZ II product family. In technical terms, they meet the same requirements as the zinc-plated version, which means that they can take extreme loads. The longer thread makes the anchors even more flexible in use. The new head stamping allows the maximum effective length of the anchors and the actual anchoring depth when installed to be controlled closely. The special drive-in pin prevents damage to the thread when the anchor is being driven into the hole. So fixtures can be removed and installed many times. There is no re-cutting of the thread needed. It saves time and costs. The outstanding features of bolt anchors are ease of handlingand quick installation. Drill the hole, drive in the anchor with a few hammer blows, tighten, done. The fischer FAZ II anchor bolt is the all-rounder for all heavy duty fixings in concrete. Using the practical and time- saving through-fixing installation, railings, brackets, awnings or framework constructions for gates can now be fixed safely. The European Technical Approval for cracked and noncracked concrete, the shock impact approval by the Federal Civil Defence Office and a fire report are proof of the high safety standards. Additionally in benefiting from preventive fire protection to F 120 the FAZ II offers high security to users. 19 20 Post-installed reinforcement connections Safe anchoring to embedment depths up to two metres Günter Seibold, Technical Support, fischer Germany The FRA composed of a rebar connected to a stainless steel threaded rod by friction welding. > To anchor post installed rebar safely in concrete, fischer offers two special systems. These rebar systems open up entirely new opportunities for structural engineers and also make professional post installed rebar applications significantly easier for site engineers and installers. Reinforced concrete is used in virtually all building constructions: foundations, (floor) slabs, beams and columns. Civil engineering construction such as bridges, tunnels or power plants are often made totally of reinforced concrete. Often, existing buildings are extended or rebuilt. This means in practice that the reinforcement of old and new sections of buildings have to be connected. Choice of two systems fischer now offers two special systems which make the installation of post installed rebar a straightforward process. The rebar is inserted, into the maximal two metres deep, drilled and cleaned holes in the concrete member. Post installed rebar are handled and loaded like cast-in rebar after the full curing time. Both systems have Euro pean Technical Approval (ETA) and a General Construction Approval by the ‘Deutsches Institut für Bautechnik (DIBt)’. The two systems are: • the established fischer Injection Mortar System FIS V based on a high-performance vinyl ester hybrid mortar for easy handling and rapid curing times. • the fischer Injection mortar System FIS EM based on best performance epoxy resin mortar for rebars up to Ø 40 mm, also suitable for diamond drill holes with easier drill hole cleaning. Optimal processing tools fischer offers all the accessories which are needed for a professional performance on the construction site: The new FIS Reinforcement Case includes all necessary special tools for approved drill hole cleaning and injecting the mortar. Holes to a depth up to two meters can be drilled for post-installed rebar. Post installed rebar are handled and loaded like cast-in rebar after completing the curing time. • The new FIS Rebar Case includes all the necessary special tools for approved drill hole cleaning and injecting the mortar. The accessories are suitable for rebars Ø 8 mm to Ø 28 mm, for hammer, compressed air and diamond drilled holes and also for applications with the fischer Rebar Anchor FRA. • For the efficient drilling of deep drilled holes, fischer supplies high-power hammer drill tools with SDS max and continuous coil for efficient drill dust removal. • The separately available drilling aid enables drill holes to run parallel to the surface of the concrete and therefore parallel to the reinforcement. This enables smaller edge distances and better static results. • There are three different application guns for different requirements. The new ergonomic, manual application gun is designed for easy injection of mortar, the strengthened compressed air gun is for rapid, stress-free filling (also with large-sized cartridges), and the new, powered application gun is for easier handling of 360 ml and 390 ml injection mortar cartridges. As good as cast-in bars Post-installed rebar has to be designed and calculated according the Euro Code EC2 or the national codes, e.g. the German DIN 1045-1, British Standard, etc. similar to conventional cast-in straight rebar in concrete. For a quick and convenient design, fischer offers the REBARFIX Design Software .This software designs post installed rebar connections to the German code DIN 1045-1 at the moment and generates a verifiable printout. Further design methods, according the EC2 and other national codes will follow. The software is available on DVD or for downloading at www.fischer.de. Training/Certification for post installed rebar connections To do the job on the site specialist knowledge is required. Therefore, fischer recommends training is performed by the fischer Academy or fischer technical field staff. In Germany, post-installed rebar applications, according to the approval, have to be completed by certified staff and companies. For more information go to www.fischer.co.uk Special anchor FRA The fischer Rebar Anchor FRA has been designed especially for extreme tension loads, e.g. at a column base, which can’t be transmitted to the concrete member by conventional anchors. The FRA is composed of a rebar connected to a stainless steel threaded rod by friction welding. Therefore it is also approved for outdoor use. The approval regulates connecting threads from M12 to M20 and allows tension loads up to 97.6 kN. 22 Residental building 101 Warren Street in New York “Jurassic Park” with FZP Dr. Klaus Fockenberg, PR Officer, fixing systems Dr. Roland Unterweger, Advanced Curtain Wall Technique > One of the United State’s most expensive high-rise apartments goes up in South Manhattan, just two blocks away from Ground Zero. The Jurassic limestone façade elements – New York’s very first façade of this kind – are held in place with fischer undercut anchors. Jura Marble Suppliers (JMS) supplied the stones. Investor Edward J. Minskoff and his architects from Skidmore, Owings & Merrill (SOM) soon agreed: nothing less than a luxury residential and business building, featuring exquisite materials and generous layouts, and with a breath taking view over New York. Work on 101 Warren Street (270 Greenwich Street) in southern Manhattan between Warren, West, Murray and Greenwich Street started in late 2006 and was finished late 2008. The unusual residential and commercial buiding features a 182 metre tower with 35 floors accommodating 228 apartments and a lower square block with a total of twelve floors, housing 163 rental apartments, a parking garage, wellness facilities, shops (15,800 m²) and restaurants, offering the buyers and tenants of New York’s most expensive and exclusive apartments a city within the city. The floor areas of the apartments vary between 85 m² and 530 m², bounded by alternating natural stone and glass façade elements which define the outer shell of the building. Visible from afar, the storey-height German-sourced Jurassic limestone panels stand out vividly from their surroundings and lend the building an unmistakable presence. The around 25,000 stone panels were fitted together into 4,000 façade elements Photos: Antamex International Inc., Toronto reportS Façade detail in the factory environment (Antamaex) The prefabricated units were slotted into position, adjusted and secured in preformed holes in the reinforced-concrete structural frame (Antamex) Natural stone from Germany The façade materials, taken from two different strata of Jurassic beige in the Altmühltal valley, were supplied by JMS, a company based in Eichstätt, Bavaria. It was here that the client and architect team, stone consultant and Canadian-based curtain wall engineer Antamex Interna tional Inc. were treated to a demonstration of fischer‘s sophisticated undercut technology. In the words of Hans Neumeyer, who as one of JMS’ partners was involved in technical counselling, „The FZP undercut anchor offers a technically efficient and aesthetically convincing solution – which is why we proposed it for this scheme.“ The project decision-makers likewise came to recognize the FZP‘s many merits, which include straightforward handling and secure installation in undercut drill holes using the automatic fischer SGB setting tool and the process and quality supervision concept developed together with Neumeyer & Brigl. JMS proceeded to dispatch a total of around 13,000 m² of cut-to-size natural stone units – equivalent to 1,400 tonnes, filling 60 containers – with the necessary undercut drill holes to Toronto-based Antamex Interna tional, which duly commissioned fischer to supply some 120,000 (13 x 21 M8W/22 A4) Zykon FZP anchors. Undercut anchors allow thinner stone panels The load-carrying capacity of the fischer undercut sys tem, which is three to five times that of conventional through-fixings, allowed the project engineers to reduce the original stone panel thickness of 5 cm to 4 cm. The lighter façade lowered the structural loads, thereby cutting construction costs. The anchors used for the 101 Warren Street project, custom-developed for sandstone and limestone walling, have been granted a national technical approval by the German Institute for Construction Technology (DIBt) in Berlin. They are 13 mm in diameter and 21 mm in length. The embedment depth in the natural stone is between 16 and 20 mm. This method, known as stand-off instal- lation, automatically compensates the tolerances in the thickness of the stones and the visible side of the natural stone façade remains totally smooth and level. Antamex International specially equipped its factory with a new assembly line for the prefabrication of the façade elements. The fischer employees visiting the company‘s Canadian base were impressed by the high standards of quality and professionalism. The around 25,000 stone panels were fitted together into 4,000 façade elements, with FZP undercut anchors set in the stone panels and bolted to an aluminium frame reinforced with steel girders. About 200 different natural stone or natural stone and glass façade elements were made using this method. Façade builders must be able to combine different materials such as natural stone, glass, aluminium, concrete and steel, which will work only with an advanced fixing method such as undercut technology. The Black Forest-based fixing specialists currently apply this highly developed technique in about 700,000 m² of façades every year worldwide. Process optimised production The prefabricated units were shipped from Toronto to the New York construction site. Here, they were craned to their respective locations in the building, slotted into position, adjusted and secured in preformed holes in the reinforcedconcrete structural frame. The great benefit of this erection method lies above all in the process-optimised production of the elements with their exceptionally high prefabrication level, the carefully co-ordinated, just-in-time panel delivery, the tightly scheduled, fast-track assembly process and the low on-site space requirement. The efficient prefabrication of curtain wall units in a factory environment guarantees a higher quality than can be achieved by assembling individual components on site. What is more, this building method causes much less noise disturbance and dust emission than conventional façade construction. 23 24 Malmö City Tunnel Special solution with FHB dynamic Oliver Ernst, Product Management third largest city. A special design of the fischer Highbond anchor FHB dynamic is used for fixing the brackets for the railing in the maintenance and service walkways. The new 9.2 kilometre City Tunnel in Malmö links the continental rail track coming from the Öresund bridge with Malmö’s main station and the Scandinavian rail network. The Öresund link between Sweden and Denmark, a combination of bridge and tunnel construction, was opened for traffic in July 2000. It connects the cities of Copenhagen and Malmö via road and rail. The new city tunnel will make the rail connection faster. The two tubes running parallel have an internal diameter of 7.9 metres. They have a total of 13 cross and evacuation tunnels spaced at 300 and 400 metres, with two shafts leading vertically up. Next to the underground station in the immediate neighbourhood of the central station, the Triangeln and Hyllie stations are also under construction, one below ground in the inner city, the other above ground on the outskirts. The award for planning and completing the entire construction lot (E201) went to the Malmö Citytunnel Group (MCG) under Bilfinger Berger AG from Germany as main contractors. The tunnel section for the Hyllie station is made in open-cast construction. The twin-cell square cross section has a clearance width on both sides of 21 metres and a clearance height between 7.20 and 9.85 metres. fischer supplied 22,000 FHB dyn 12 × 100/15 C, 1,150 cartridges FIS HB 345 S, almost 9,000 threaded rods RG M10 × 130 C, 5,800 threaded rods FIS A M10 × 100 C as well as over 14,000 additional nuts M10 C. All the anchor rods, washers and nuts are made of highly corrosion-resistant steel (1.4529). The Highbond anchor FHB dyn 12 × 100 / 15 C used in the construction is a special version, developed specifically for the Malmö City Tunnel by Technical Sales Support with development support from Denzlingen. The anchor is accompanied by special installation instructions which also describe the re-assembly which will be necessary in about 40 years. After that time, the brackets must be renewed. The brackets held by the Highbond anchor FHB dyn are fixed to the concrete tunnel tubbings via foot plates. They carry a fire pipeline and cable routes. Due to the train traffic, the bracket fixings had to be designed for dynamic loads. Somewhat less demanding were the requirements and specifications for fixing the hand rails and earthing rails along the service and maintenance walkways and for fixing the earthing rail in the tunnel roof. The threaded rods FIS A and RG M were used, with an extra counter nut added to the usual nut and washer to prevent the fixing from working loose through train vibrations.

For scientific support for the engineering task, fischer Italy has cooperated with University of Padua’s Prof. Paolo Lazzarin, an expert in the field of material fatigue. Fixings for noise barriers along high-speed railway tracks are subject to special requirements > A joint study by the University of Padua and fischer Italy about the fatigue performance of threaded rods fixed in concrete with fischer epoxy resin FIS EM shows positive results. In the course of the cooperation, an extensive series of tests was carried out at the Denzlingen laboratories on the fatigue behaviour of threaded rods with different diameters set in concrete with the FIS EM injection mortar. The tension and bending tests were made in accordance with fischer’s Technical Handbook. The investigations showed clearly that the weakest part of the system is the steel threaded rod in the region just below the nut where the tension forces concentrate. The results were very satis factory as far as the behaviour of the epoxy resin was concerned: no failures were found, either in the resin mortar or in the concrete. On the strength of these results, fischer Italy was approved by the Italian railway company to fix threaded rods in an important noise barrier project with FIS EM. Fixings for noise barriers along high-speed railway tracks are subject to special requirements. A study commissioned by the Italian railway engineering company Italferr on the dimensioning and load-bearing behaviour of noise barriers resulted in some dramatic changes to the previous design methods. Fatigue tests are now the key criteria for testing components such as anchorings, profile sections and panels. The appropriate standards and norms are currently being updated or developed further. This also applies to the definition of the test structure and the test protocols, both for Italian (UNIFER, UNI, GL 31 group) and international fischer FIS EM reportS Klaus Fischer Customer Centre in Tumlingen The solitaire Dr. Klaus Fockenberg, PR Officer, fixing systems > From the first ground-breaking ceremony to the inauguration, it took just over a year to build the new customer centre of the fischer group of companies. This modern building has been designed and is used mainly for training and instruction. The design by the architects Lieb + Lieb of Freudenstadt was chosen by a panel chaired by Professor Klaus Fischer on the strength of its functional and aesthetic qualities. The completion of the new building took about 13 months. The short planning and construction period is down to the good team work between planners, engineers, authorities and trades on the one hand, and between the owner and the in-house construction professionals on the other hand. Although the customer centre is integrated into the existing buildings of fischerwerke, it is perceived as a solitary diamond as a result of its raised position. In the context of the compact works complex, the Klaus Fischer Customer Centre with its exciting and dynamic envelope stands in the limelight against the existing cubic buildings. When lit, the sophisticated lighting design underlines this impression. Wood and glass in the lobby lend this area a bright and friendly atmosphere. The air space linking every level allows sight contact with all floors. The ground floor accommodates the work and workshop rooms of the AKADEMIE and the fischer World, an area which shows fischer’s full range of products in their practical use with one-to-one scale models. This part of the building is fully separated in terms of acoustic A glazed colonnade connects the customer centre with the staff restaurant sound-proofing. The upper level houses the seminar rooms and staff offices. At Level 1, the staff restaurant and other seminar rooms are reached via the wide connecting corridor, which is generously glazed and framed with black facing concrete columns. Glass cabinets and exhibition items displaying and presenting art, products and the fischer company itself line this corridor. A volume of over 16,000 cubic metres and a net ground area of 3,300 square metres show the dimensions of the new Klaus Fischer Customer Centre where about 3,000 people will now be trained and instructed every year. 27 28 Refurbishment of Province of Rovigo administration building, (Italy) Ventilated façade using photovoltaic modules Marzia Viel, Marketing, fischer Italy The photovoltaic panel solution was installed on the south and south-east walls. 400 sq m of amorphous silicon photovoltaic modules were placed on the walls with a cavity of about 30 cm to improve module heat exchange and building insulation. The solution adopted involved the use of fischer Structur Easy sections with dimensions of about 14 cm applied on a plate to enable the total dimensions to be covered. For maximum safety and performance on the different supports, the fischer FAZ II anchor bolt was used on concrete, while the chemical fixing fischer FIS V 360 S was used on brick sections. The structure includes vertical sections in extruded aluminium alloy 6060 T 66 positioned as per the project, fixed to the wall with anchoring brackets connected to the support with mechanical or chemical bolts/threaded rods in aisi 304 stainless steel. The photovoltaic modules were placed on the walls with a cavity of about 30 cm. > In Rovigo, the capital of the province of Rovigo, near Venice, the main provincial administration building has been modernised with a new façade using various fischer products. The building dates back to the 1960s. The work had the two-fold purpose of recladding the facade of the structure and improving the building’s energy performance. These works required the fischer StructurEasy 11 – 14 support frame system combined with the new fischer Solar-fix (Profilo Solar Plus and pre-assembled clamps). The substructure is completed with a single horizontal section positioned according to the pitch of the modules, the function of which is to transfer on to the struts the loads of the photovoltaic panels and the stresses caused by wind. These sections are fixed with self-locking sliding blocks joined together by self-perforating screws in aisi 304 stainless steel. The anchoring brackets are made of aluminium alloy 6060 T 5 with holes to give the assembly tolerances as laid down by the UNI 11018 Standard and compatible with the b earing structure, fastened by appropriate expansion clips with associated hardware in aisi 304 stainless steel. The photovoltaic modules are fastened to the horizontal transoms by preassembled aluminium terminals complete with A 2 stainless steel screws and aluminium hammered nuts.

This work step is extremely important in connection with injection mortar (adhesive systems) because any drill dust remaining in the drill hole will “substantially and significantly” reduce the load-bearing capacity of the bonded anchor. The installation eye bolts are glued in using the fischer injection mortar FIS V 360 S which is very popular among mountaineers because of its rapid curing. Another advantage is its colour which hardly differs from the colours of the surrounding rock strata. Pull-out tests showed no changes in the anchoring and steel zone The pull-out test results in detail: • Anchor 1: cracks developing in limestone at an axial > Mountaineering and climbing are growing in popularity among hobby athletes. With their products, fischer also has the right solutions for this leisure market. In the effort to make mountaineering or climbing a pleasant and safe experience, many communities in Austria fit their existing climbers’ walkways and parks with new anchoring points and fall guards set in natural rock. In the climbers’ paradise “Imster Gorge” in the Tyrolean Oberland, fischer Austria carried out a series of tests, with the following installation eye bolts anchored in the limestone: tension load of 8 kN (approx. 800 kg), no changes in the steel zone • Anchor 2: no changes observed in the anchoring and steel zone at an axial tension load of 20 kN (approx. 2,000 kg) A • nchor 3: no changes observed in the anchoring and steel zone at an axial load of 26 kN (approx. 2,600 kg) This test series demonstrated that matching components and materials, the careful setting and use of the products and a thorough knowledge of the mountaineering and climbing sport are of crucial importance. 29 30 Restoration with fischer FRS System Restoring the arches of the Gardens of Palazzo Chigi in Ariccia (Rome) Enrico Di Donato, fischer Italia Area of activity > The use of the fischer FRS System on the arches of the “Antica Uccelliera” (a former aviary) in the Palazzo Chigi in Ariccia is part of a larger project for the refurbishment and restoration of the gardens of Palazzo Chigi. The architectural artefacts inside the gardens, such as the aviary, including the “Portale dei leoni” or Lions’ Gate, are now archaeological ruins. Many elements of the buildings are in a state of advanced deterioration. In addition to the passing of time and to weathering, one of the decisive factors that had led to such deterioration is the widespread growth of vegetation which has caused serious damage to the architecture (the roots and plants are often impossible to separate from the masonry). While analysing the project, it was found that many pieces were completely or partly missing from the various facings of the brickwork structures of the two large arches cover- ing the “Uccelliera”. The state of deterioration affected all of the architectural artefacts, from the springer to the keystone. With a view to preserving these assets and considering their nature as “romantic ruins”, the idea was to consolidate and protect the existing structures starting out from a thorough analysis of the situation “as it is”. There must originally have been four or five large arches on the site, of which there now remain only two. The two arches were in such a precarious state of decay that it was necessary to make the structures safe immediately, by means of suitable supporting works. The first arch has lost its original shape, and relative shifting of the two semiarches on opposite sides of the opening has occurred, with probable separation of the cross-sections at the height of the haunches, while the second arch is unstable due to the formation of a strap between the keystone and the left-hand springer of the structure. REPORTS The structural activity proposed for consolidating the two large arches has the aim of providing support but altering the original static layout as little as possible, in an approach based on reversibility and respect for the present architectural context. It was precisely in order to respect these fundamental requirements that it was decided to apply a reinforcement made of carbon fibre-reinforced plastic, fischer FRS CS 240 with the epoxy resin fischer FRS CB, that, in addition to being strong and durable, is certainly not invasive. Before applying the reinforcement system to the extrados, of course, a suitable system for shoring up the whole structure was created. In view of the dilapidated state of the two masonry structures, it was necessary to repair beforehand the missing parts of the arches by inserting salvaged material and mortar consisting of hydraulic lime and pozzolana. It was then possible to continue repairing the retaining masonry of the arches by means of “patchworked” masonry using salvaged material and non-shrink mortar. Non-shrink mixtures were also injected into the masonry facing. Before going on to arrange the carbon fibre strips, the surface of the extrados of the arch was prepared, making the surface regular with a layer of thixotropic mortar with fibre reinforcement. Then three one-directional longitudinal carbon fibre strips, fixed with fischer FRS CS 240, 20 cm wide and 0.13 mm thick with a substance of 240 g/m², were put into place. In order to ensure better adhesion to the underlying structure, crosswise connecting strips of onedirectional carbon fibre (CFRP) 0.13 mm thick and with a substance of 240 g/m² were arranged every 100 cm. Lastly, the activity was completed with the reconstruction of a new support with solid brickwork. In addition to the activities described above, consolidation of the second arch called for additional activity in the retaining area on the left. Specifically, partial reconstruction of the springer Three one-directional longitudinal carbon fibre strips fischer FRS CS 240, 20 cm wide and 0.13 mm thick with a substance of 240 g/m² were put into place. area was necessary, using the patchwork technique, with salvaged fragments and non-shrink mortar, ensuring perfect engagement of the new parts in the existing rocky wall by inserting three bars with a diameter of 12. Inclusion of the carbon fibre reinforced material In this case, a numerical analysis of the behaviour of the structures in the presence of the reinforcing system was carried out, highlighting the benefits for the masonry in terms of stresses and shifting. Numerical modelling has enabled the artefacts in question to be re-created, simulating suitably the actual constraining to the springers and introducing – in addition to the vertical loads caused by the weight of the masonry – a horizontal seismic action in the direction of the plane of the arches. 31 32 National company fischer France Ever closer to the customer Thierry Kuntz, fischer France The Strasbourg offices – the headquarters of France’s best known and most innovative brand in the field of construction fixings fischer international > Since 2002, there have been substantial changes at fischer’s sales organisation in France. This process, covering several stages, has followed a schedule with the aim of working closer with dealers. Our Strasbourg-based French subsidiary is structured into four distinct departments corresponding to the different sales channels: engineering and industrial supplies, building material trade, sanitary and load-bearing systems, and DIY. They are all reporting to Marketing and Sales managed by Alain Ménager who also defines and coordinates the whole of the sales strategy. Depending on sales channel, the different product ranges are also on offer with different sales concepts, the appropriate presentations and packaging specifically matching the different types of sales and distribution. The fischer France team organised a very special event for their customers during the Batimat in Paris Each department features its own customer reception area, order handling, active customer support and operative marketing which is attuned to the special requirements and needs of each sales channel and takes account of the uniform appearance of the fischer brand in the market. Technical engineers in a separate department for special applications, managed by Gilles Dalon, focus solely on the support of customers in the construction industry. Support comes from the Technical Department headed by Jean-Marc Berg, in charge of the development of product ranges, user support and training and instructing customers and fischer’s sales force. “The fischer group of companies is definitely customerdriven”, says manager Alain Bruder. “We have not accomplished our leading position for all times: it is given to us by our users and their dealers. But this also means that we know them well and understand their expectation”. The people working for fischer therefore put all their effort into meeting exactly what their dealers and their users of fixing systems expect from them. Alain Bruder: “We owe it to ourselves to see to it that we guarantee our customers the reliability and quality, especially when it comes to solv ing technically demanding issues, which they rightly expect from a great brand such as fischer. The whole of fischer France’s team is ready and motivated to keep this promise”. The Expert Club established in 2007 is one of the instruments used to promote closeness to the customers. The dealers give the Club their sales data and, in return, they get access to the full sales statistics of fischer France, brokendown into products and types of customers based on a customer archive which meanwhile boasts 7,500 users. The dealers also benefit from special actions and campaigns, a bonus point program with giveaways, a specific newsletter and from the website www.club-expert.fr which allows them direct access to fischer France’s technical centre. Thanks to fischer France’s new sales organisation, unique in the fischer group of companies, they succeeded in creat ing new decision-making areas. Knowing the customers better, a more detailed knowledge of what the users need and faster response in solving customer-specific problems are the outcome. At the same time, these changes at fischer France have given our subsidiary a more professional image among our customers. This is the result of the most recent brand awareness survey by GFK Custom Research 2008 which showed that fischer has reversed the trend since 2002 and that, for 70 % of the consumers interviewed, we offer a product range not so much for private households but for trade and industry. fischer is meanwhile not only the best known brand in France, but is also seen as the most innovative brand which always offers the most suitable solutions. Our subsidiary in France is determined to continue the development of the fischer brand in France and communicates its dynamic approach and basic values – innovation, respectability and responsibility – by adorning the large glass façade of its offices in Strasbourg with a theme. It shows a climber appearing to climb up a façade, secured by just a single anchoring point, with the added slogan above “Inspirer les hommes, concevoir le future” (inspiring people, planning the future). 33 34 SFS unimarket – fischer’s distribution partner in Switzerland Photo: SFS unimarket AG Otmar Büchel, SFS unimarket AG Wide-ranging supply chain management solutions, optimised In the direct distribution business, SFS unimarket has already and tailor-made, are offered and provided by SFS unimarket in the accomplished market leadership for fischer fixing system in Switzerland service segment > DSFS unimarket AG, Swiss partner of fischer fixing systems since 1 January 2003, has achieved its market objectives in just under seven years.

A total of 75,000 fixing sets with the new fisher spacer in combination with the fischer nail anchor FNA II 6 x 30/20 A4 and a marking pin were supplied via SFS unimarket and installed for a fire protection subsection at the southern end of the tunnel. About 19,000 concrete screws fischer delivers for the subsection Amsteg, carried out by SFS unimarket. 35 36 FNA II A4 for tunnel in Lyon For the first time in France, fischer’s nail anchor FNA II A4 has been used in a tunnel refurbishment project in the town of Lyon. The French company Prezioso carried out the installation of Promat fire boards, under the supervision of the Swiss control office Bonnard & Gardel in the tunnel project, which is called “Brotteaux Servient”. In total, 7,000 square meters had to be protected with fire boards and therefore, 40,000 FNA II A4 anchors in different lengths had to be installed. After several tests, all the parties involved were really impressed by the simple way to set the anchor, as well as by the loads such a small anchor can take. Thanks to the excellent cooperation between all departments in France and in Germany, even unique challenges could be overcome. These included the production and delivery of the FNA II A4 in a special length within 10 days, to the complete satisfaction of the client. Restoration of York Minster York Minster is a Gothic cathedral, which along with Cologne cathedral is one of the largest in Europe. fischer UK is assisting with a five-year project to help stonemasons protect and repair the famous heritage building. Much of the detailed stonework is hewn from magnesian limestone The current project involves replacing pinnacles on the roof and spires of the gothic structure. For fixing these, stainless steel dowels are used. Following testing on fischer resins the dowels are being fixed with vinyl ester resin FIS V 360 or epoxy FIS EM 390 S. fischer resins are also involved in the installation of replacement manganese bronze ties to hold together sections of stonework on the façade of the building. Barcelona Metro line L 9 In Barcelona the new underground line L 9 is under construction. After completion it will pass under the city with a length of 46.6 km and will link the International Airport with the suburb of Can Zam. More than 50 sta tions are planned along this, the longest underground line in Europe. The line, which will run completely auto matically, follows a two-storey tunnel. The construction project is divided into several phases and will not finish before 2014, because of ongoing problems with its construction. The main fischer product, as is often the case on tunnelling projects, is resin both for fixing rebars and for other applications as well. The products used included the FIS EM 1100 S, FIS V 360 S and FIS VT 380 C. A highlight of the project was the use of 3,000 FIS EM 1100 S for fixing rebars between decks and slurry walls in a 600 m tunnel in the south of the city.

Titelphoto New Porsche Museum in Stuttgart, Dr.-Ing. hc F. Porsche AG Netherland’s highest residential tower block, 158 metres in height, is being constructed in Rotterdam. The 45-storey building is named “New Orleans” and has been designed by the Portuguese architect Alvaro Siza. Official completion date is in 2010. Around 20,000 fischer nail anchors FNA II 6 x 30/75 A4 were used for fixing the frame constructions of the aluminium facade windows and the sliding doors of the loggias. The anchor was chosen because of its small drill hole diameter and its rapid installation. 4,100 short FNA II 6 x 30/5 A4 hold the side sections of the frames in the loggias in the concrete. Sliding doors the height of the floor are installed into the loggias in the west and east façade. To absorb the high wind pressure forces, the frames are fixed directly to the concrete floor above using a total of 6,500 SXS 10 x 120 A4. The lower frames are anchored in the concrete with around 3,400 anchor bolts FAZ II M12/10 A4. Also, over 4,250 hammerset anchors EA M16 x 65 were used for temporary fixings, around 20,000 nail anchors for various applications, and the Upat EXA and the injection mortar FIS V 360 S were used in the building.

It will have 75 storeys dedicated to offices. The installation of the stone façade started in summer 2009. The façade of the tower will be made from a combination of glass-aluminium windows, natural stone and Jura marble from JMS of Germany. When finished the Al Hamra will be the highest stone-clad building in the world. The façade elements were prefabricated in China by Wuhan Lingyun Building Decoration Engineering Co. Ltd, and shipped to Kuwait. The stones are attached to the pre fabricated elements with approximately 100,000 fischer FZP anchors for limestone. The designer, Skidmore, Owings and Merrill (S.O.M.), of New York, USA, the general contractor Ahmadiah Contracting & Trading Co. of Kuwait, and the façade consultant Arup of Hong Kong, decided to work with FZP anchors from fischer following an intensive two-day presentation on the features and benefits of the product.
