| 摘要 |
The invention consists of a semi-resistant prefabricated slab of concrete of variable dimensions to which the blocks 5 of expanded polystyrene, the concrete 6 and the required negative reinforcements 7 are added, on site, in order to form the filler material. Likewise, connections are made between slabs which make it possible for them to be able to behave as a unidirectional (one-way) or bidirectional (two-way) filler material. <IMAGE>
