Composite floor slab structure and construction technology thereof
The invention discloses a composite floor slab structure. The composite floor slab structure comprises a prefabricated bottom plate and a cast-in-situ concrete layer, the prefabricated bottom plate islaid on composite beams or cast-in-situ beams at the two ends and provided with laying-end steel bars, and the upper end faces of the prefabricated bottom plate and the composite beams or cast-in-situ beams are covered with the cast-in-situ concrete layer. The invention further provides a construction technology of the composite floor slab structure. According to the composite floor slab structure and the construction technology thereof, the thickness of the prefabricated bottom plate is increased, water and electricity pipelines are embedded into the prefabricated bottom plate, and the prefabricated bottom plate is hollowed as far as possible to decrease the dead weight; and the cast-in-situ concrete layer is thin, supports do not need to be arranged under a floor slab when concrete is cast in situ, the construction technology is simplified, and the integrity of the floor slab structure can be guaranteed.
一种叠合楼板结构，包括预制底板和现浇混凝土层，所述预制底板搁置在两端的叠合梁或现浇梁上，所述预制底板设有搁置端钢筋，所述现浇混凝土层覆盖所述预制底板和叠合梁或现浇梁的上端面。以及提供一种叠合楼板结构的施工工艺。本发明提供一种叠合楼板结构及其施工工艺，增加预制底板的厚度，在预制底板中预埋水电管线，且尽可能将预制底板空心化，以减轻自重；现浇混凝土层较薄，现浇混凝土时不必在楼板下设置支撑，简化施工工艺，也能保障楼板结构的整体性。
