Connections have to be dimensioned in accordance with engineering principles, including the hand rail loads and the wind loads acc. to DIN 1055-3 and DIN 1055-4. Verification of the immediate local transmission of forces into the concrete is provided.Transmission of the loads to be anchored inside the component has to be verified separately.The reduction of the cross-sectional area of the concrete due to the installation of anchor channels has to be taken into account for the static proof, where applicable. The connection element is to be designed for the occuring loads globally using the elastic/elastic method acc. to DIN 18800-1:1990-11. It has to be proved, that the anchor plate is sufficiently rigid against bending.The bolts may not be exposed to perpendicular load with lever arm (bending). This is achieved, if the following is observed:

the connection element is made of metal and tightened against the channel without intermediate layer, -the ho - le diameter in the connection element does not exceed the value of the bolt diameter by more

than 2 mm. The centerline of the bolt must be at least 2,5 cm off the end of the channel. Apart from that the bolts can be arranged in any order. The specifications in appendix 6, table 6, are to be observed. The anchor channel may be stressed by tensile load, transverse load and a combination of tensile and transverse loads perpendicular to the channel axis. Additional loads which may arise in the anchor channel, the component to be connected or in the component where the anchor channel is anchored as a result of obstructions to dimensional change (e.g. temperature changes) shall be taken into account. Occuring temperature impacts due to subsequent welding of balustrade parts to the anchor plate may not cause any deformations on it, in order to ensure an overall contact with the concrete surface.Load components parallel to the channels longitudinal axis are not permitted.

The effects HEd, VEd, MEd and NEd are to be detemined according to the calculation principles in appendix 7.

The ratio between the acting horizontal load and the bending moment is according to the dimensioning method limited to:

It has to be proven, that the design value of the effect (load) Ed does not exceed the design value of the resistance (strength) Rd:

For the design values of the effects in the most simple case (permanent load and a variable load acting in the same direction) the following applies:

HEd / MEd ≤ 1,5 [1/m] HEd in [kN]; MEd in [kNm]

Ed ≤ Rd (see table 3.1 and 3.2)

Ed = design value of the effect (NEd, VEd, MEd)

Rd = design value of the resistance (NRd, VRd, MRd)

Ed = γG * Gk + γQ * Qk

Gk ; Qk = characteristic value of a permanent or a variable effect according to the applicable standards on assumed loads

γG ; γQ = partial safety factor for permanent resp. variable loads

max (NEd/ NRd,s) + max (VEd/ VRd,s) ≤ 1,2

2.) MEd/ MRd,c + 1,5 VEd/ VRd,c ≤ 1,5 for 0,333 ≤ VEd/ VRd,c ≤ 1,0

The design resistances of the channels against steel and concrete failure for fixings with 1 bolt must be taken from appendix 8, table 8a and for fixings with 2 bolts from appendix 8, table 8b. Also the design resistances of the bolts acc. to appendix 8, table 9, are to be observed. For the proof of the load capacitiy against concrete edge failure the design resistance of the concrete compression zone MRd,c is to be determined acc. to the calculation principle in appendix 8.

A minimum reinforcement consisting of stirrups and longitudinal bars, dependent on the anchor channel profile, must be provided according to appendix 6, table 7. Thereby one stirrup has to be arranged symmetrically between the anchors and one stirrup near to each anchor on the exterior side respectively.

It is not permissible to subsequently apply anchors on the anchor channel or to carry out any other modifications.

The installation of the anchor channel has to be carried out according to the design drawings that have been prepared in accordance with section 3.1.1., in due consideration of the construction principles acc. to appendix 6, table 6. The indicated edge distances are minimum dimensions. Any under-run of these dimensions has to be avoided by appropriate measures.

The required bolt size must be taken from the design drawings.

The heads of the bolts are inserted into the channel opening and after a clockwise rotation by 90° they must be solidly seated on both anchor channel lips, and locked by tightening the nut with the torque wrench. The tightening torques specified in appendix 4 must be observed.

After installation the correct seating of the bolt must be checked. The marking notch at the bolt’s shaft end must be perpendicular to the channel’s longitudinal direction. The center line spacing of the bolts must not be less than the values specified in appendix 6, table 6.

Size and position of the anchor plate to be attached must be detemined according to the design drawings provided according to section 3.1.1 with regard to the construction principles according to appendix 6, table 6. The surface of both the anchor plate and the concrete must be carried out such, that a close contact between both is guaranteed.

A back anchoring reinforcement according to appendix 6 must be provided, and it must be ensured, that its position is secured.

The anchor channels have to be fastened to the formwork in such a way that they are not dislocated when the reinforcement is laid and the concrete is poured and compacted. The concrete must be properly compacted in the area of the channels and underneath the head of the anchors. The anchor channels must be protected against concrete penetrating the channel interior.

The contractor put in charge of the installation of the anchor channels or the construction supervisor assigned by him or a competent representative of the construction supervisor has to be present on the site during installation of the anchor channels, the back anchoring reinforcment and later during the bolt installation (fastening of connecting components). He has to ensure that the work is executed properly.

In particular, he has to check the execution and position of the anchor channels as well as the required additional reinforcement.

After the concreting the position of the anchor channel must be checked again with regard to the compliance with the minimum edge distances. Minus tolerances are not permissible. Records must be available on site during the construction period and have to be submitted to authorised supervisory personnel on request. After completion of work, they have to be archived by the contractor in the same way as delivery notes for at least five years.
