Prefabricated cast-in-place concrete floor
The invention belongs to the technical field of building structures, and particularly relates to a prefabricated cast-in-place concrete floor. The prefabricated cast-in-place concrete floor comprisesa prefabricated plate and a cast-in-place plate, and the prefabricated plate is designed to be in a C shape; the prefabricated plate is formed by pouring concrete and a frame; the frame comprises cross beams, longitudinal beams and connecting ribs; the cross beams are made of C-shaped groove steel materials; the number of the cross beams is two, and openings of the cross beams are oppositely designed; assembling grooves are formed in the two ends of the cross beams; the longitudinal beams are made of I-shaped steel materials; the longitudinal beams are fixedly connected into the assembling grooves through bolts; and connecting grooves are formed in the longitudinal beams. According to the prefabricated cast-in-place concrete floor, the cross beams and the longitudinal beams are arranged tobe combined to form the frame, first through grooves and supporting grooves are formed, the two symmetrically-designed cross beams are tensioned through the connecting ribs and nuts, and therefore the formed frame has certain prestress; and meanwhile, an elastic truss is erected in the frame defined by the cross beams and the longitudinal beams, and therefore the manufactured prefabricated platehas high strength under the thin size.
本发明属于建筑结构技术领域，具体的说是一种预制现浇混凝土楼板，包括预制板和现浇板，所述预制板“C”形设计；所述预制板由混凝土和框架浇筑而成；所述框架包括横梁、纵梁和连接筋；所述横梁为“C”形槽钢材料制成；所述横梁数量为二且横梁开口相对设计；所述横梁两端均开设有组装槽；所述纵梁为工字钢材料制成；所述纵梁通过螺栓固连于组装槽内；所述纵梁上开设有连接槽；本发明通过设置横梁和纵梁组合形成框架，并开设第一通槽和支撑槽，使用连接筋和螺帽将对称设计的两个横梁进行拉紧处理，使形成的框架具备一定的预应力，同时将弹力桁架架设在横梁和纵梁围绕成的框架内，进而使制得的预制板在较薄的体积下即具备高强度。
