II SPECIAL PROVISIONS

1 Subject of Approval and field of application

1.1 Subject of Approval The JORDAHL anchor channel JXA (type W 29/20, type W 38/23, type W 53/34, type W 64/44) consisting of a C - shaped channel with teeth and at least two weld-on anchors arranged on profile backs or pressed round anchors of mill-finish steel in design or hot dip galvanised and in stainless steel. Hammer-head T-bolts or tooth bolts including respective nuts and washers are used in the channel, with which any construction parts can be fastened. The anchor channel is set flush with the surface in concrete. In Appendix 1, the anchor channel is shown in the installed state.

1.2 Area of application The anchoring channels may be used for anchorages under primarily static loading in reinforced or unreinforced normal concrete and under fatigue-related central tensile loading up to 2 106 load cycles in reinforced normal concrete of strength grade C12/15 according to DIN EN 206-1 "Concrete Part 1: Specification, performance, production and conformity" are used. For demands on the fire resistance duration of concrete structures in which the anchor channels are anchored, the restrictions as described in Section 3.2.7 must be observed. For fire exposure the anchor channel may only be loaded perpendicularly to the channel longitudinal axis. The anchor channel may also be used for anchorages primarily subject to static load in lightweight concrete with closed structure of strength grade of at least LC25/28 (aggregate of expanded clay, expanded shale or pumice) in accordance with DIN EN 206-1, provided that no demands are put on the overall construction including the anchor channel in terms of fire resistance duration. For anchoring in the tension zone of the concrete generated from load stresses or when utilising the minimum distances of the anchor channels, the local transverse tensile stresses occurring due to explosive effect must be absorbed by additional reinforcement, unless no structural measures or other favourable effects (e.g. shear pressure) prevent concrete from splitting. The areas of application of the anchor channel (channel profile, anchor, T-bolt, nut and washer) in regard to corrosion are to be specified with respect to the selected materials in Appendix 5, Table 7. A galvanised anchor channel (channel and anchor) may stand only in connection with reinforcement, when the temperature at the contact points between the reinforcement and the galvanised steel parts does not exceed 40°C. In pre-stressed concrete components the distance of a galvanised anchor channel (channel and anchor) must be at least 2 cm from the cladding tubes of the pre-stressed element or the pre-stressed wire with immediate bonding. When hot dip galvanised channels are used with stud anchors made of stainless steel, then the cladding tubes of the pre-stressed elements or the pre-stressed wires can be in connection with the T-bolts of stainless steel, but must not touch the hot dip galvanised channel.

2 Provisions for the structural product

2.1 Properties and composition The structural parts of the anchor channel (channel, anchor, T-bolt, nut and washer) must comply with the drawings and specifications of the equipment. The material characteristic values not specified in this General Building Approval must correspond to the specifications deposited with the Deutsches Institut für Bautechnik, and with the external monitoring unit information. In addition, the provisions of the General Building Approval Z-30.3-6 "Products, fasteners and structural components made of stainless steels" are to be observed.

2.2 Fabrication and labelling 2.2.1 Fabrication (connection channel/anchor)

The fabrication of the connections (welding, press-fitting) between the anchor and the channel has to take place at the factory. With regard to the verification of suitability of the welding operation DIN 18800-7:2008-11 "Steel Structures, Part 7 is valid: Execution and constructor's qualification". The round anchors are inserted and pressed in the factory through a prefabricated hole in the back of the channel.

2.2.2 Labelling Packaging, package inserts or delivery note of anchor channels and T-bolts must be labelled by the manufacturer with the conformity mark (Ü-mark) in accordance with the conformity mark regulations of the federal states. In addition, the identifying mark, the approval number and the full name of the anchor channels and T-bolts is to be specified on the delivery note. The marking may only be made if the conditions of Section 2.3 are met. The anchor channel is designated according to the outer dimensions of the rounded profile of the channel (width/height in mm), e.g. Profile JXA-W 38/23. The T-bolts are designated according to the bolt type (toothed T-bolt types JXD, JXH or JXB, hammer-head T-bolt types JD and JH) and the thread size and assigned to the profile dimensions. Each anchor channel must be identified in accordance with Appendix 5. The T-bolts have to be labelled and embossed according to Appendices 3 and 4.

2.3 Proof of Conformity 2.3.1 General

The confirmation of conformity of the anchor channels and T-bolts with the provisions of this General Building Approval must be carried out for each manufacturing plant with a declaration of conformity based on a factory production control and a regular external monitoring including an initial test of the anchor channels and T-bolts in accordance with the following provisions. For the issuance of the declaration of conformity and the external monitoring including the product inspections to be carried out, the manufacturer of the anchor channels and T-bolts has to consult with a recognised certification body and an approved monitoring body. The manufacturer shall hand over the statement that a declaration of conformity is issued by marking the structural products with the conformity mark (Ü mark) with a note on the intended use. The certification authority has to provide the Deutsches Institut für Bautechnik with a copy of the declaration of conformity they have issued, for information. The Deutsches Institut für Bautechnik is to be provided with an additional copy of the initial test report.

2.3.2 Factory production control A production control system is to be set up and operated in each manufacturing factory. Under factory production control, one understands the continuous monitoring of production that is established by the manufacturer, with which it ensures that the structural products the company manufacture comply with the provisions of this General Building Approval. For the scope, nature and frequency of factory production control the control plan deposited with the Deutsches Institut für Bautechnik and the external monitoring body shall prevail. The results of factory production control are to be recorded and evaluated. The records must contain at least the following information: - Designation of structural product or raw material and components - Type of control or testing - Date of manufacture and testing of the structural product or raw material or

components - Results of the control and tests and, if applicable, comparison with the requirements - Signature of the factory production control managers.

The records must be kept for at least five years and submitted to the appointed external monitoring body. They are presented to the Deutsches Institut für Bautechnik and to the responsible supreme construction supervision authority. In case of unsatisfactory test results, the manufacturer must immediately take the necessary measures to rectify the defect. Structural products which do not meet the requirements shall be handled such that confusions with conforming products are excluded. Once the defect is rectified, the remedial testing must be repeated immediately as far as it is technically possible and necessary.

2.3.3 External monitoring In each production works, the factory production control should be checked regularly by an external monitoring body, at least twice a year. As part of the external monitoring, an initial test of the anchor channels and T-bolts must be carried out and also samples must be taken for random sample testing. The sampling and tests are subject to the respective accredited monitoring body. For the scope, nature and frequency of external monitoring the control plan deposited with the Deutsches Institut für Bautechnik and the external monitoring body shall prevail. The results of certification and external monitoring must be kept for at least five years. Upon demand they have to be presented to the Deutsches Institut für Bautechnik and to the responsible supreme construction supervision authority by the certification body or by the monitoring body.

3 Provisions for design and dimensioning

3.1 Draft The anchorages shall be designed by an engineer. By considering the loads to be anchored, verifiable calculations and drawings are to be prepared. The drawings shall include details on location, size and length of the anchor channels and on the T-bolt type and the size of the corresponding bolts.

3.2 Dimensioning 3.2.1 General

The anchorages are to be dimensioned by an engineer. Proof of direct local force transfer into the concrete is provided. When verifying the anchor channel according to the partial safety factors, the design resistance FRd yields to 1.4 perm. F. The transfer of the loads to be anchored into the component must be verified. Weakening of concrete section by installing anchor channels is to be considered in static analysis, if necessary. Additional stresses that may arise in the anchor channel, in the component or in the part, in which the anchor channel is anchored, from disabled deformation (e.g. during temperature changes) are to be taken into account. The action of unit load or load pairs may take place at any point of the anchor channels. The axis and end distances of the load application points (T-bolts) are given in Appendices 7 and 8. The axis of the T-bolt must be at a distance of at least 25 mm from the channel end. The minimum distances of the anchor channels (axis, edge and corner distances) and component dimensions (component width and thickness) according to Appendix 6 must not be undershot.

3.2.2 Permissible loads The permissible loads of the anchor channels are indicated in Appendix 8, Table 11,

depending on the profile length, the load intervals and corresponding T-bolts for concrete strength grades C20/25.

For anchoring in concrete with the strength grade C12/15, permitted loads for C20/25 should be reduced by a factor of 0.7 and in lightweight concrete with closed structure LC25/28 by the factor 2/3. The permissible load directions (loading areas) for anchor channels are shown depending on the type of bolts in Appendix 7. When using the hammer-head T-bolt (types JD and JH) the anchor channel may be only loaded perpendicular to the channel longitudinal axis (shear load and central tension). When using the toothed T- bolt (types JXD, JXH and JXB) the

anchor channel may be loaded in all directions (longitudinal tension, lateral tension and central tension). With simultaneous stress in several directions, the resultant load must not exceed the permissible load according to Appendix 8, Table 11.

The permissible loads of the bolts are given in the Appendices 3 and 4. The smaller value (of anchor channel or T-bolt) shall prevail. 3.2.3 Bending stress of T-bolts

The permissible bending moments are indicated in the Appendices 3 and 4. The calculated clamping point is the top edge of the anchor channel. A bending stress may only be disregarded where - the component to be connected is made of metal and is braced without intermediate

position against the channel and - the through hole in the component to be connected, does not exceed the values in the

Appendices 3 and 4, Tables 4 and 6. For bending with additional central tension or diagonal pull, the stresses must be superimposed:

Fz ≤ perm. F (1 - M/perm M.) perm. F = permissible central tensile load of the T-bolt according to Appendices 3 and 4 perm. M = bending moment of the T-bolt according to Appendices 3 and 4

F z = existing tensile load component ≤ permissible load of the anchor channel (Appendix 8)

M = existing bending moment. In facade cladding with variable bending stresses (e.g. as a result of temperature changes) the stress amplitude σA = ± 50 N/mm² may not be exceeded by the mean value σM based on the calculated stress section of the T-bolt.

3.2.4 Fatigue relevant central tensile loads in reinforced normal concrete ≥ C12/15 For a stress load from fatigue-related central tensile loads with a number of load cycles

N ≤ 2106 the anchor JXA-W 29/20, JXA-W 38/23, JXA-W53/34 and JXA-W 64/44 may be used in the version with shear T-anchors and with round anchors. The permissible stress amplitude is specified for a number of load cycles N ≤ 2106 in Appendix 8, Table 12. The anchor channels may be anchored in reinforced normal concrete of at least C12/15. Only the corresponding T-bolts according to Appendix 8, Table 12 are allowed.

3.2.5 Special case of narrow reinforced concrete components An anchor channel arranged in the front face of at least 10 cm thick lightly loaded reinforced concrete structures (e.g. as facade panels, lightly-loaded traffic walls) may only be subjected to permissible central tensional load according to Appendix 8, Table 11, when an additional reinforcement is provided in accordance with Appendix 9.

3.2.6 Displacement behaviour Under allowable loading amount, the displacement of ≤ 0.6 mm can be expected towards the load: For shear loads, the existing hole clearance between T-bolt and component has to be additionally considered.

3.2.7 Fire protection With regard to demands on fire resistance duration of concrete components, the anchor channels may be primarily loaded statically only perpendicularly to the channel axis (central tension, diagonal pull and shear load) in reinforced normal concrete of strength class C12/15 under static and quasi-static loading. The permissible loads for each anchor channels are indicated in Appendix 10, Table 13 depending on the bolt size for the fire resistance of 90 minutes (F90) or 60 minutes (F60) and must not be exceeded. The anchor channels may be used for one-sided fire exposed reinforced concrete floors, three-sided fire reinforced concrete beams and four-sided fire exposed reinforced concrete columns. For one-sided, fire-exposed, reinforced concrete floor, the minimum axis distance of the tensile reinforcement in the anchor channel area has to comply with Appendix 10, Table 14. For three-sided fire exposed reinforced concrete beams and four-sided fire

exposed reinforced concrete columns, the axial distance "u" of the reinforcement according to DIN 4102-4 is to be increased by the value "Δu" specified in the Appendices 11 and 12, Tables 15 and 16. If the anchor channels are installed in concrete components (reinforced concrete slabs, bars and columns) of fire resistance class F60 or F90 and the conditions specified in the Appendices 10 to 12 are complied with, the fire resistance class of the concrete is retained. The assessment of the fire resistance duration for the structure to be connected is not subject of this Approval.

4 Provisions for the implementation

4.1 Installation of anchor channels No anchors may be subsequently fixed nor other changes made to the anchor channel. The installation of the anchor channel must be made in accordance with design drawings in

Section 3.1.1. The anchor channels shall be attached to the formwork so that they do not move during

reinforcement installation or during introduction and compaction of concrete. The concrete must be compacted properly between the channels and under the head of the anchor. The anchor channels are to be protected against ingress of concrete into the channel cavity.

4.2 Mounting the connection construction (bolt mounting) The required bolt type and size is found in the design drawings. Under a load in the longitudinal direction of channel only the toothed T-bolt type JXD and type JXH may be used. This T-bolt is marked on the shaft end by two marking slots. If due to incorrect concrete introduction, etc., the front edge of the anchor channel is not flush with the concrete surface, this gap must be padded under the entire surface during installation of the connection structure. The heads of the T-bolts are inserted into the channel slot, must fully rest on both legs of the anchor channel after a clockwise rotation of 90° and be locked by tightening the nut with the torque wrench. The tightening torques specified in Appendices 3 and 4 must be complied with. After assembly, the correct seat of the T-bolt is to be checked, the marking slots on the shank end of the bolt must stand transversely to the longitudinal channel direction. The axial distance of the T-bolts (load distance) must not fall below the specifications of Appendix 7 and/or Appendix 8.

4.3 Control of the execution When installing the anchor channels and T-bolt installation (fastening of connection structures) the contractor entrusted with installing the anchor channels or the construction manager appointed by him or a proficient representative of the construction manager must be present on site. He is responsible for proper execution of work. In particular, he has to check the design and position of the anchor channels and the possibility of supplementary reinforcement. The records must be readily available for this purpose during construction on the site and upon demand they must be submitted to the monitoring officer. The records as well as the delivery notes must be kept by the contractor after the work, for at least 5 years.

exposed reinforced concrete columns, the axial distance "u" of the reinforcement according to DIN 4102-4 is to be increased by the value "Δu" specified in the Appendices 11 and 12, Tables 15 and 16. If the anchor channels are installed in concrete components (reinforced concrete slabs, bars and columns) of fire resistance class F60 or F90 and the conditions specified in the Appendices 10 to 12 are complied with, the fire resistance class of the concrete is retained. The assessment of the fire resistance duration for the structure to be connected is not subject of this Approval.

4 Provisions for the implementation

4.1 Installation of anchor channels No anchors may be subsequently fixed nor other changes made to the anchor channel. The installation of the anchor channel must be made in accordance with design drawings in

Section 3.1.1. The anchor channels shall be attached to the formwork so that they do not move during

reinforcement installation or during introduction and compaction of concrete. The concrete must be compacted properly between the channels and under the head of the anchor. The anchor channels are to be protected against ingress of concrete into the channel cavity.

4.2 Mounting the connection construction (bolt mounting) The required bolt type and size is found in the design drawings. Under a load in the longitudinal direction of channel only the toothed T-bolt type JXD and type JXH may be used. This T-bolt is marked on the shaft end by two marking slots. If due to incorrect concrete introduction, etc., the front edge of the anchor channel is not flush with the concrete surface, this gap must be padded under the entire surface during installation of the connection structure. The heads of the T-bolts are inserted into the channel slot, must fully rest on both legs of the anchor channel after a clockwise rotation of 90° and be locked by tightening the nut with the torque wrench. The tightening torques specified in Appendices 3 and 4 must be complied with. After assembly, the correct seat of the T-bolt is to be checked, the marking slots on the shank end of the bolt must stand transversely to the longitudinal channel direction. The axial distance of the T-bolts (load distance) must not fall below the specifications of Appendix 7 and/or Appendix 8.

4.3 Control of the execution When installing the anchor channels and T-bolt installation (fastening of connection structures) the contractor entrusted with installing the anchor channels or the construction manager appointed by him or a proficient representative of the construction manager must be present on site. He is responsible for proper execution of work. In particular, he has to check the design and position of the anchor channels and the possibility of supplementary reinforcement. The records must be readily available for this purpose during construction on the site and upon demand they must be submitted to the monitoring officer. The records as well as the delivery notes must be kept by the contractor after the work, for at least 5 years.
