<p>Formwork for containing a concrete casting, adapted to form the resting surface for a floor, roofing or similar structure of a building. The formwork is made up by stool-shaped elements (15) which are moulded out of plastic material and are joined to each other by allowing their side edges to overlap, while leaving vertical cavities (16) open between contiguous elements. These cavities are then closed on top by means of stoppage elements (18) adapted to prevent the cast concrete from penetrating them. <IMAGE></p> |
