Abstract (en)
The filler (1), comprising a body (2) with an under-surface (3) and two side surfaces (4) with projections that rest on the projecting edges (18) of reinforced concrete joists (17), is made from a cellular plastic material with the under-surfaces of its outer edges covered with a layer of an adhesive sheet material that is resistant to traction. The filler (1), comprising a body (2) with an under-surface (3) and two side surfaces (4) with projections that rest on the projecting edges (18) of reinforced concrete joists (17), is made from a cellular plastic material with the under-surfaces of its outer edges covered with a layer of an adhesive sheet material that is resistant to traction. The sheet material, which is between 30 and 500 microcentimeters thick and has a weight of between 50 and 250 g/sq m, can cover the whole under-surface of the filler and is made from a polymer and/or kraft paper, or woven/non-woven synthetic or natural fibres or glass fibre mesh optionally impregnated with adhesive.
