Formwork-erecting-free self-bearing prefabricated ribbed beam concrete hollow laminated slab
The invention discloses a formwork-erecting-free self-bearing prefabricated ribbed beam concrete hollow laminated slab. The formwork-erecting-free self-bearing prefabricated ribbed beam concrete hollow laminated slab comprises a prefabricated cement fiberboard and a plurality of prefabricated ribbed beams which are transversely arranged along a floor slab at intervals and extend in the longitudinal direction of the floor slab; a hollow body is arranged between every two adjacent prefabricated ribbed beams, and the hollow bodies are fixed to the prefabricated cement fiberboard through rivets; and the prefabricated rib beams are fixedly connected with the prefabricated cement fiberboard through connecting plates fixed at the bottom of the prefabricated rib beams, a concrete entity is pouredon the prefabricated cement fiberboard, and the hollow bodies and the prefabricated rib beams are embedded in the concrete entity. According to the formwork-erecting-free self-bearing prefabricated ribbed beam concrete hollow laminated slab, the floor slab is high in rigidity and light in weight, secondary beams can be reduced, the clearance of a building is increased, and the appearance is attractive; and experimental research and engineering practice prove that the working performance of the laminated slab is completely the same as that of an overall cast-in-place concrete slab, and the laminated slab can be used as a bidirectional slab.
本发明公开了一种免支模自承重预制肋梁混凝土空心叠合板，包括预制水泥纤维板和多根沿楼板横向间隔设置、沿楼板纵向延伸的预制肋梁，在相邻的两根所述预制肋梁之间设有空心体，所述空心体采用锚钉固定在所述预制水泥纤维板上，所述预制肋梁通过固定在其底部的连接板与所述预制水泥纤维板固接，在所述预制水泥纤维板上浇筑有混凝土实体，所述空心体和所述预制肋梁埋设在所述混凝土实体内。采用本发明的楼板刚度大，重量轻，可减少次梁，增加建筑物的净空，外观美。试验研究及工程实践证明，采用本发明的叠合板的工作性能与整体现浇的混凝土板完全相同，可以按双向板使用。
