Abstract (en)

[origin: EP2050887A2] The girder (1) has walings (4) passing in a longitudinal direction of the girder and a cross stay chain (5) welded at the walings. The chain has upper bends (6) between diagonally bent vertical bars (2, 3). Anchorage elements (7) i.e. round or flat steel bar sections, are attached to the bends of the chain upwardly and/or downwardly in the girder for applying bar forces in a concrete of a cover e.g. flat slab. Free gaps (Z) are formed between the elements in a longitudinal direction of the girder without the walings.
