Introduction and application The Superfloor 88, a trapezoidal profiled galvanized steel sheet, is the ideal replacement for concrete floors. All important characteristics of steel and concrete are merged into one whole and used for load-bearing floors. Furthermore, large spans are possible and openings are easy to apply during construction. In addition, after installation of the Superfloor 88 the floor can immediately be used as a work floor. The Superfloor 88 is applicable to any type of floor, in some situations may be a temporary propping necessary during construction phase. The high profiled steel sheets lead to a highly flexible system and low weight. Also, suspension systems for pipes and ceilings are easy to install. And above all, the Superfloor 88 is quick and easy to assemble. The Superfloor 88 can be used in two ways. By mounting the metal sheets the other way round, for example, heavier reinforcement could be used. The design offers a wide range of applications. Superfloor 88 is the alternative for floors in car parks till residential houses. For example the placement of a floor in an existing building, but also for the realization of parking roofs provides the Superfloor 88 a solution. Of course meets the design in most situations without additional fire-resistant applications to the fire resistance requirements according the Dutch standards. In short, the Superfloor 88 permit savings, thanks to a quick assembly and the lower floor weight compared to other systems. In this global manual you can find the possible applications, advantages, characteristics of the steel sheets and finished floor, standard specification definition, storage and processing advice. Furthermore, there are examples of calculations including the permitted variable load. For detailed advice, tailored to your design, please contact our technical advisors. Applicable in different sectors, such as: Industrial buildings Office buildings Storage Parking decks and garages Hospitals Residential houses 2 Benefits The great advantage of the Superfloor 88 are the enormous time savings. The steel profiled sheets are rapidly and easy to install, furthermore the assembly is not weather sensitive and are conduits and pipes easy to mount. Precisely these and below mentioned product benefits makes that the Superfloor 88 can bring interesting savings on the total construction costs. Competitive with comparable systems. Short delivery time. Economical to transport inlands and overseas. The plates will be delivered in bundles, in advance tailor made lengths. Suitable for every type of floor, in some situations with temporary propping. Quick and easy assembly without additional crane costs. After installation suitable work floor. Solid alternative for concrete floors 2 Superfloor Continuing of works on underlying floor, when propped. Lower floor weight is less demanding on the support structure and the foundation(s) and saves on the total construction costs. Openings can be determined and applied in situ. This reduces the construction costs and saves time. Without additional amenities thirty minutes fire resistant. Adequate soundproofing. Large spans possible. Standard accessories, such as end seals are available. Superfloor 88 can be used on both sides, making heavier reinforcement possible. Integrated pipelines and ceilings easy to install with existing asseccories. Execution: Sendzimir galvanized steel. 88 3 Characteristics of Superfloor 88 3.1 Safe work floor The Superfloor 88 is after installation directly suitable as a safe work floor. Furthermore, the floor provides protection against all kinds of weather for people who work underneath. 3.2 Strong duo When using the Superfloor 88, all important characteristics of steel and concrete are merged into one whole and used for flooring. It is a profiled steel sheet which is used in the first phase as a permanent shuttering, capable of loads, such as weight of fresh concrete and mounting loads to bear. 3.3 Field reinforcement partially or completely unnecessary After curing of the concrete, the profiled steel sheets and the concrete are one constructive whole. By merging these products and (if applicable) reinforcement steel, one bearing structure will occur. 3.4 Large spans possible Large spans are possible, depending on the floor thickness and the additional reinforcement. If, for example, during construction temporary support can be placed, spans of 8 to 9 meters are possible. 3.5 Material specifications Nominal sheet thickness (including zinc coating): : Profile height : Working sheet width : Total sheet width : Execution Solid alternative for concrete floors 0,75 and 1,00 mm 88 mm 618 mm +/- 652 mm (may vary slightly) Sendzimir galvanized steel (S280GD Z275) 3 Superfloor 88 4 Characteristics finished floor Safety and reliability. Important concepts, which the Superfloor 88 meets. A fire-resistance of 30 minutes without additional amenities. Superfloor 88 meets the requirements of the loads and the deformations of the TGB 1990-NEN 6702, the requirements of the NVN-ENV 1994 (Euro code 4 dated January 1998) and the RSBV 1990. 4.1 Floor weight and concrete volume finished floor The own weight and concrete volume of the floor is: Slab depth (mm) Concrete volume m³/m² Total weight kg/m² sheet 0,75mm Total weight kg/m² sheet 1,00mm Slab depth (mm) Concrete volume m³/m² Total weight kg/m² sheet 0,75mm Total weight kg/m² sheet 1,00mm 150 160 170 180 190 200 0,092 0,102 0,112 0,122 0,132 0,142 240 265 290 315 340 365 244 269 294 319 344 369 210 220 230 240 250 0,152 0,162 0,172 0,182 0,192 390 415 440 465 490 394 419 444 469 494 The weight of the finished floor meets concrete requirement B25 4.2 Fire-resistance The great advantage of the Superfloor 88 is its own fire-resistance of 30 minutes without additional amenities. If a higher fire- resistance is required than this can be solved by a fire-resistance coating (at the bottom), additional reinforcement or a fire- resistant ceiling. By adding, for example, additional reinforcement a higher fire-resistance will be achieved. On request, fire load tables per floor type will be provided. 4.3 Acoustic capability The finished floor has an acoustic capability that is proportional to the mass and provides an adequate soundproofing. The properties are similar to those of a flat floor with a thickness equal to the average thickness of a composite slab. 4.4 Mechanical properties The final product strength is according to the calculations of the engineer. After curing the deflection meets the TGB 1990. On request by floor type load tables will be provided. See also Chapter 7 Load tables, calculation examples section. 5 Transport and storage 5.1 Cost-efficient transport The Superfloor 88 also offers great advantages during transport. The elements easily fit together and therefore costeffective to transport, because they take up less valuable space. 5.2 Advice transport and storage on location Protect against rain and contamination. Dry transport and storage. Ensure there is sufficient ventilation to avoid condensation. Store packs clear of the ground and with a fall of 2°. Stack the wooden packing crates on top of each other. Superfloor 88 up to 7 meters can be lifted by fork lift trucks. Superfloor 88 longer than 7 meters should be lifted by crane, with wide woven webbing slings (7cm) that grab around the wooden packing crates. Solid alternative for concrete floors 4 Superfloor 88 6 Suitable for different floor types 6.1 Floor types Superfloor 88 can adapt well to different floor types with various supports. So the floor is easy to install on the following surfaces: steel beams brickwork precast concrete beams hat beams reinforced strips 6.2 Practical examples for design (see also chapter 9 Specification text) min 50 min 70 overlap = 20 mm min 50 min 100 6.3 Connection with a metal support structure In order to ensure the connection between the steel structure and the concrete, shear studs can be used. This has the advantage that realization of dual beams is possible and it allows optimization of the steel structure. For this you can use two types of shear studs, namely: the welded shear stud and the powder actuated, direct fixed shear stud. Shear stud The Superfloor 88 should be in perfect contact with the steel beam. The upper flange of the beam should be unpainted, dry and clean at the location of the welded shear stud. The maximum spacing of the studs in the longitudinal direction depends upon the design Shear connector The Superfloor 88 should be in perfect contact with the steel beam. Place the shear studs flat on the steel sheet and fix with two nails The maximum spacing of the studs in the longitudinal direction depends upon the design Solid alternative for concrete floors 5 Superfloor 88 7 Load tables The load tables indicate the maximum variable load that can be incorporated. The weight of the composite floor slab is already deducted. The total applied load referred to in the load tables is a working load 7.1 Principles calculation method 7.1.1 Span The indicated spans are center-to-center distances of the underlying beams. There is a span of up to 8500mm possible. Larger spans are not excluded, the floor thickness will then be increased. Please consult our technical advisors. 7.1.2 Concrete quality Starting from a minimum concrete quality B25. 7.1.3 Temporary propping The load tables indicate when temporary propping is required. The propping should remain for at least 14 days. 7.1.4 Load capacity In the variable load tables, the own weight of the composite floor is taken into account. For additional loads consult our technical advisors. 7.1.5 Upper reinforcement The upper reinforcement should be calculated for each situation. 7.2 Calculation examples In the load tables that follow the permitted variable load on the finished floor in relation to the following appears: the static system (1,2 or 3 fields), floor thickness and free span. Usually the span and the load are a fixed value, resulting from the design. In the tables the appropriate structure can be chosen. Accordingly, the thickness and applicable reinforcement. By choosing an element having more reinforcement, the floor thickness can be reduced. The tables are suitable for the most common floor thicknesses. Of course, other thicknesses, spans and variable loads are possible.

Solid alternative for concrete floors 12 Superfloor 88 8 Processing during construction The Superfloor 88 is economically advantageous due to rapid installation and no formwork removal. Due to the low weight and the high rate of reinforcement the substructure and foundation can be performed lighter. When pouring the concrete, the steel profiled sheets provide a solid work floor and protects the lower floors. Moreover Superfloor 88 generates a very high ratio strength / weight. Superfloor 88 can be installed in single span or more spans, in which the imposition of the plate must be at least 50 mm. 8.1 Installation of the sheets To prevent movement by wind or during pouring, is a good fixing of the plates at imposing extremely important. 8.1.1 Fixing sheet / end bearing At installation of a sheet at the point of an end bearing, each trough of the sheet must be fixed with one shooting nail or screw (depending on the surface). 8.1.2 Fixing longitudinal seams At fixing of the longitudinal seams, it is necessary to fix the plates with each other, c.t.c. 300mm, with teks or rivets. This is necessary to prevent sliding of the metal sheets during the pouring of the concrete and to prevent it from leakage water. 8.1.3 Butt joined placed sheets If the sheets are installed with a butt joint (end to end), we recommend to seal the seam with a tape of 50mm width. 8.1.4 300 mm End closures type KU type KI 8.2 type GI type GU Forming holes An important part of plant, ventilation ducts and pipes can be included in the composite floor. Creating openings for vertical transit in the profiled steel sheet is possible by applying polystyrene blocks or formwork before pouring concrete. After pouring the steel sheet may only be processed, after full curing of the concrete, using a nibbler or saw. If only one crest is cut, this will require no additional facilities. When two or three crests are cut this must be compensated with reinforcing bars at the left and right of the recess. With larger recesses or shortly after each other penetrations located perpendicular to the profile direction is that this should be considered as a single large penetration. In this case it must be provided by appropriate additional reinforcement or steel edge profiles. Please refer to our technical advisors.

These have to be installed before pouring in the crest of the steel sheet. 8.4 Reinforcement One of the most important properties of the Superfloor 88 is that it acts as a field reinforcement. The reinforcement is a structural element and has as its purpose to absorb the forces that the concrete layer takes. Namely, concrete has the characteristic that it can only absorb compressive forces and no pulling forces. Since a floor is loaded with pulling force, the so called lower reinforcement must absorb the forces. The upper reinforcement is designed to absorb the shrinkage in the concrete. The picture clearly shows how the spacer centers the lower reinforcement. This is a fixed distance from the Superfloor 88 to ensure optimum coverage. By mounting the Superfloor 88 reversed, additional field reinforcement can be applied. NOTE: When using the composite floor on several supports, the upper reinforcement must be calculated! 8.5 Advice before and during pouring Before the start of the pouring all dirt and grease, that have an adversely affect on the hardened slab, must be removed. During pouring directly spread the concrete and prevent accumulations. Furthermore, work from the support points to the center of the span. From an aesthetic point of view we recommend to remove any leaking cement water with water. 8.6 Use of temporary supports If working with temporary supports is necessary for the span chosen, then the same method can be used as for a broad slab floor. Please note: that before pouring propping needs to be in the middle of the span with one temporary support, with two temporary supports the props need to be at 1/3 of the span, also see load tables. At the spot of the props the Superfloor 88 must never be interrupted, because it is a temporary support. When the bottom of the Superfloor 88 remains in sight, it is of great importance that the surface of the props is sufficient. This is to prevent that an imprint of the props is seen on the steel sheet by influence of the concrete weight.
