Prefabricated ribbed bottom plate concrete composite floor slab and construction method thereof
The invention provides a prefabricated ribbed bottom plate concrete composite floor slab and a construction method thereof, and relates to the technical field of constructions.The prefabricated ribbed bottom plate concrete composite floor slab comprises a prefabricated ribbed bottom plate and a cast-in-place layer, the prefabricated ribbed bottom plate comprises a flat plate and ribbed plates arranged along the flat plate at intervals, and a plurality of rectangular grooves are formed in the bottom face of each ribbed plate at equal intervals; a plurality of transverse ribs are arranged in the length direction of the rib plates at equal intervals, all the transverse ribs penetrate through rib penetrating holes in the rib formwork and are arranged in a staggered mode with the rectangular grooves, longitudinal ribs perpendicular to the transverse ribs are arranged between the two rib plates, and all the longitudinal ribs and the transverse ribs are bound and fixed to form a reinforcing mesh. A concrete formwork of the cast-in-place layer is poured on the reinforcing mesh and connected with the prefabricated ribbed bottom plate into a whole, and therefore the problems that according to an existing prefabricated ribbed bottom plate concrete composite floor slab, distribution bars are difficult to penetrate through, and cast-in-place concrete is difficult to connect into a whole are solved.
本发明提供了一种预制带肋底板混凝土叠合楼板及其施工方法，涉及建筑技术领域，包括预制带肋底板以及现浇层，所述预制带肋底板包括平板以及沿所述平板间隔布设的肋板，所述肋板的底面等距设置有多个矩形槽，沿所述肋板的长度方向等距设置有多个横向筋，各所述横向筋贯穿肋模板上的穿筋孔设置，并与所述矩形槽相错位排布，两所述肋板之间配置有与所述横向筋垂直的纵向筋，各所述纵向筋与所述横向筋绑扎固定以形成钢筋网；所述现浇层的混凝土支模浇筑在所述钢筋网上，并与所述预制带肋底板连为一体，从而改善现有预制带肋底板混凝土叠合楼板分布筋穿筋困难、现浇混凝土难以连成整体的问题。
