| 摘要 |
The invention concerns mushroom floors made of reinforced concrete, without dropped girders, consisting of shuttering floor slabs, with the possibility of a small rectangular drop called an abacus, placed above each post, having approximate dimensions 0.80 m x 0.80 m x 0.08 m. The shuttering floor slabs can be prefabricated or prestressed. The simple and rapid use consists in: after casting the posts, positioning the other abaci 2 (which can be prefabricated, for example of fibre concrete), then positioning the main shuttering floor slabs 3 and finally the shuttering floor slabs of the centre 4. Finally, all that remains is to position the reinforcement which is to go in the cast-in-place concrete and to cast the latter. <IMAGE>
