II. SPECIAL PROVISIONS
1.
Subject of the Approval and area of application
1.1
Subject of the Approval
The anchor channel type PEC-TA comprises a C-shaped channel made of hot rolled steel
with at least two anchors welded onto the back of the profile and PEC special screws (Tbolts) with corresponding hexagon nuts and washers. The channel is concreted in flush
with the surface.
The anchor channel is illustrated in the installed state in Annex 1.
1.2
Area of application
The anchor channel is to be used only for anchorages subject to static or quasi-static
loading in reinforced or unreinforced normal weight concrete of strength class from C12/15
to C90/105 according to EN 206-1:2000-12. The anchor channel may be anchored in
cracked and non-cracked concrete.
The anchor channel may be used for transmission of tensile loads, shear loads, or a
combination of tensile and shear loads perpendicular to the longitudinal axis of the
channel.
The intended use of the anchor channel (channel profile, anchor, special screw, washer
and nut) concerning corrosion is given in Annex 3, Table 1 depending on the chosen
material.
In the case of anchoring in the tension zone of the concrete produced by load stresses or if
the minimum spacing of the anchor channels is used, the local transverse tensile stresses
occurring as a result of the springing action must be absorbed by additional reinforcement,
if constructive measures or other beneficial influences (e.g. transverse pressure) do not
prevent the concrete splitting.
A galvanized anchor channel may be connected to reinforcement only when the
temperature of the contact point between the reinforcement and the galvanized steel parts
does not exceed 40°C.
For pre-stressed concrete members the spacing between a galvanized anchor channel and
the jacket tube for the tendon or strand for immediate bond has to be at least 2 cm.
2
Provisions for the structural product
2.1
Properties and composition
The anchor channel corresponds to the drawings and information given in Annex 2 to 7.
The characteristic material values, dimensions and tolerances of the anchor channels
and bolts not specified in this General Building Approval must correspond with the
specifications deposited at the German Institute for Structural Engineering, at the
certification office and at the third-party monitoring office.
2.2
Manufacture and identification
2.2.1 Manufacture (connection between channel and anchor)
The production of the connections (welding on, pressing) between anchor and channel is to
be performed in the factory.
Note:
No. Z-21.4-2032
th
2.2.2 Marking
Each delivery note of the anchor channels and bolts must be marked by the manufacturer
with the compliance symbol (Ü symbol) according to the compliance symbol regulations of
the German regions. In addition, the works code, the approval number and the complete
description of the anchor channels and bolts must be specified on the delivery note. The
marking may be carried out only if the preconditions according to Section 2.3, Verification
of compliance, have been satisfied.
The anchor channel is described in terms of the type of manufacture and the profile
dimensions, e.g. PEC-TA 40/22 according to Annex 2.
Each special screw must be marked with the works code and if applicable the strength
class according to Annex 2.
2.3
Verification of compliance
2.3.1 General
The confirmation of the compliance of the anchor channels and bolts with the provisions of
this General Building Approval must be carried out for each factory with a certificate of
compliance on the basis of in-house production control and regular third-party monitoring,
including initial testing of the anchor channels and bolts in accordance with the following
provisions.
In order to grant the certificate of compliance and the third-party monitoring, including the
product tests to be carried out in the process, the manufacturer of the anchor channels and
bolts has to involve a certification authority recognized for this purpose and also a
monitoring authority recognized for this purpose.
The producer has to issue a declaration that a certificate of conformity has conferred for
the construction product by marking with the Ü-sign with reference to the intended use.
The Deutsche Institut für Bautechnik must additionally be provided with a copy of the
certificate of conformity, for information.
2.3.2 Factory production control
In each factory, in-house production control must be set up and carried out.
In-house production control means the continuous monitoring of the production is to be
performed by the manufacturer, with which it is ensured that the structural products
produced by it correspond with the provisions of this General Building Approval.
The factory production control shall be in accordance with the control plan which is part of
the technical documentation of this European technical approval. The control plan is
decribed in the context of the factory production control system operated by the
manufacturer and deposited with Deutsches Institut für Bautechnik.
The results of the factory production control must be recorded and evaluated. The
recordings must contain at least the following information:
- Designation of the structural product or of the raw material and the constituent parts
- Type of inspection or testing
- Date of manufacture and testing of the structural product or the raw material or the
constituent parts,
- Result of the inspection and tests and, if relevant, comparison with the requirements
- Signature of the person responsible for the factory production control.
The recordings must be kept for at least five years and presented to the monitoring
authority involved in the third-party monitoring. They must be presented to the Deutsches
Institut für Bautechnik and the responsible highest building inspection authorities on
Note:
No. Z-21.4-2032
th
demand.
In the event of an inadequate testing result, the requisite measures for rectifying the
deficiency must be taken by the manufacturer without delay. Structural products which do
not meet the requirements must be handled in such a way that confusion with identical
parts is ruled out. After the deficiency has been rectified - to the extent technically possible
and required in order to verify the elimination of the deficiency - the existing testing must be
repeated without delay.
2.3.3 Third-party monitoring
In each factory, the in-house production control must be checked regularly, but at least
once per year, by a third-party monitoring authority. Within the context of the third-party
monitoring, initial testing of the anchor channels and bolts must be carried out, and
samples must also be taken for random sample tests. Sampling and testing is in each case
the responsibility of the recognized monitoring authority. Decisive for volume, kind and
frequency of the third-party monitoring is the test plan deposited at the Deutsches Institut
für Bautechnik. The results of the certification and third-party monitoring must be kept for at
least five years. They must be presented to the Deutsches Institut für Bautechnik and the
responsible highest building inspection authorities on demand by the certification or
inspection body.
3
Provisions for design and dimensioning
3.1
Design
Taking account of the loads to be anchored, checkable calculations and design drawings
must be prepared. The design drawings must contain precise specifications relating to
position, size and length of the anchor channels and the bolt type and the size of the
associated bolts. The materials of the anchor channel and the special screw has to be
given on the drawings additionally.
3.2
Dimensioning
3.2.1 General
The design of the anchorage is based on the CEN/TS 1992-4:2009 "Design of fastenings
for use in concrete", part 1 and 3 under the responsibility of an engineer with experience in
anchorages and concrete work. The verification for shear load with supplementary
reinforcement follows CEN/TS 1992-4-3:2009, section 6.3.6 and 6.3.7 or alternatively
Annexes 16 and 17.
The reduction of the member cross section caused by the anchor channel is taken into
account for the verification of the concrete member if necessary.
The member thickness has to be not less than hmin indicated in Annex 8, Table 7.
The edge distance of the anchors on the profile back of the channel is not less than cmin
indicated in Annex 8, Table 7.
The spacing of the anchors is between the smin and smax given in Annex 6, Table 4.
The spacing of the special screws is not less than smin,s given in Annex 9, Table 8.
The effective anchorage depth is not less than min hef according to Annex 8, Table 7.
The characteristic resistances are calculated with the minimum effective anchorage depth.
Note:
No. Z-21.4-2032
th
3.2.2 Design resistance
The characteristic values for the design of anchorages are given in the Annexes 8 until 17.

Provisions for the use of the product
4.1
Installation of the anchor channel
The fitness for use of the anchor channel can only be assumed, if the following installation
conditions are observed:
- Installation by appropriately qualified personnel and under the supervision of the
person responsible for technical matters on site.
- Use of the anchor channel only as supplied by the manufacturer without exchanging
the components.
- Installation in accordance with the manufacturer's specifications given in Annexes 18
and 19 and the design drawings.
- The anchor channels are fixed on the formwork such that no movement of the
channels will occur during the time of laying the reinforcement and of placing and
compacting the concrete.
- The concrete under the head of the anchors are properly compacted. The channels
are protected from penetration of concrete into the internal space of the channels.
- Size and spacing of special screws correspond to the design drawings.
- Orientating the special screw (notch according Annex 7) rectangular to the channel
axis.
- Observation of the prescribed values (e.g. Tinst according Annex 9) of installation.
- The setting torques given in Annex 9 must not be exceeded.
4.3
Monitoring the implementation
During the installation of the anchor channels and during the mounting of the bolts (fixing of
connecting constructions), the contractor entrusted with the anchoring of anchor channels
or the construction manager commissioned by him or a specialist representative of the
construction manager must be present on the building site. He must ensure the proper
implementation of the work. In particular, he must monitor the implementation and position
of the anchor channels and any possible rear-suspended reinforcement. The recordings
must be available during the construction period on the building site and must be presented
to those entrusted with the supervision on demand. Just like the delivery notes, they must
be kept for at least five years by the contractor after the work has been completed.
