Abstract (en)

[origin: EP0295417A2] In previous composite building slabs for sectional false floors, which are supported at their four corners and consist of an upwardly open trough produced from tension-proof material and of a filling of compression-proof material, e.g. anhydrite, a greater deflection is produced, under load, at the edge of the slab than in the centre of the slab, which is undesirable. In order substantially to even out the load-bearing capacity and security of composite building slabs of the above type against breaking at the edge of and in the centre of the slab, provision is made on the side walls (6g) of the trough (3g) for a reinforcement which is virtually at the height of the slab and is non-positively connected to the base (5) of the trough. In addition or alternatively to this, it is also possible to increase at least twofold the density and strength of the filling (2) in the edge region of the composite building slab (10g) relative to the remaining region towards the centre of the slab. <IMAGE>
