<p>A floor slab member (1) comprising an upper slab (3) and a lower slab (2) made of reinforced or non-reinforced concrete and which are interconnected by concrete coupling members (5) between which there are provided concreteless spaces formed by a solid or non-solid mould (6) made of relatively light material. The mould is provided with longitudinal sidewalls (8) for forming coupling members having the form of continuous longitudinal side edges (4) between upper and lower slab and having openings contiguous with wall portions substantially perpendicular to the plane of the floor slab member. At least some of said wall portions as well as the sidewalls have a height equal to that of the coupling members.</p> |
