| 摘要 |
The prefabricated reinforced concrete member (1) intended for producing floors possesses, on its top side, i.e. in its top boom, recesses in the form of individual longitudinally extending channels (7) which open out on the front sides and into which can be inserted, in the region of local supports (9), as required, reinforcements (8) serving to absorb moments at support. According to a preferred embodiment, the prefabricated reinforced concrete members (1) have longitudinally extending mutually parallel cavities (3), at least some of which, in certain regions, are open to the top in order to form the channels (7). A further subject of the invention is a floor made of such prefabricated reinforced concrete members (1) having an in-situ concrete which fills the intervening space (10) between adjacent floor bays and also the channels (7) and in which the reinforcements (8) of the top boom of the prefabricated members (1) are embedded, bridging the support (9). <IMAGE> |
