Assembled integral type hollow floor system based on prefabricated bottom plate
The prefabricated bottom plate-based assembled integral hollow floor system comprises prefabricated reinforced concrete bottom plates which can be spliced with one another, splicing seam connecting pieces used for butt joint are arranged at the splicing ends of the prefabricated reinforced concrete bottom plates, and the prefabricated reinforced concrete bottom plates are spliced with one another to form splicing seams distributed in the longitudinal and transverse directions; bottom plate steel bars are arranged in the prefabricated reinforced concrete bottom plates and extend out of the prefabricated reinforced concrete bottom plates, the extending steel bars of the adjacent prefabricated reinforced concrete bottom plates and the abutted seam connecting pieces are in butt joint at abutted seams respectively, and concrete is cast in place at the abutted seams to form concrete beam ribs. The risk that concrete pouring of the lower flange of the cast-in-place concrete hollow floor is not compact and segregated is thoroughly eliminated, the risk that a filling body of the cast-in-place concrete hollow floor floats upwards is thoroughly eliminated, the integrity of the hollow floor and the construction quality of a concrete structure can be reliably guaranteed, and consumption formworks are completely avoided.
本发明公开一种基于预制底板的装配整体式空心楼盖，包括可相互拼接的预制钢筋混凝土底板，所述预制钢筋混凝土底板拼接端设置有用于对接的拼缝连接件，预制钢筋混凝土底板之间相互拼接并形成沿纵横向分布的拼缝，所述预制钢筋混凝土底板内设置有底板钢筋并外伸至板外，相邻预制钢筋混凝土底板的外伸钢筋之间、拼缝连接件之间分别对接于拼缝处，在拼缝处现浇混凝土形成混凝土梁肋；彻底消除现浇混凝土空心楼盖下翼缘混凝土浇筑不密实和离析的风险，彻底消除现浇空心楼盖填充体上浮的风险，能够可靠保证空心楼盖的整体性和混凝土结构施工质量，并完全避免采用消耗性模板。
