H A L F E N H L B LO O P B OX Product description, load capacit y according to EC 2, application examples Minimum reinforcement, alignment Load capacity for applications according to EC 2 The official approval applies for construction elements under predominantly static loads. If imposed deformations due to e.g. temperature changes or outdoor weathering can not be excluded, the crack width of the junction has to be restricted to wk ≤ 0.3 mm. Transverse loads do not lead to an additional crack opening. The product is not designed for regular tension loads. To include the expansion forces...

H A L F E N H L B LO O P B OX Information on the constructive load bearing behaviour Note: for the officially approved product combinations refer to the information given in this brochure (→ Pages 6 - 9) and in the official approval documents. The following notes provide a basic understanding of the load bearing behaviour for the constructive application. However they are not to be considered as normative proofs. 1. Transfer of tension loads perpendicular to the joint The transfer of tension loads results from the overlap of the wire loops (fig. 1). In the area of the loops the compression loads...
