Fabricated steel-concrete combined hollow laminated floor system and construction method thereof
The invention discloses a fabricated steel-concrete combined hollow laminated floor system and a construction method thereof, and belongs to the technical field of fabricated buildings. The laminated floor system comprises a prefabricated lower cover plate, a cast-in-place upper cover plate and a steel bar truss, the lower cover plate is provided with a lower notch used for being in lap joint with a lower flange of a steel beam in the span direction, a web of the steel beam is provided with bar penetrating holes allowing first lap joint steel bars to penetrate through, and after the first lap joint steel bars penetrate through the corresponding bar penetrating holes, the first lap joint steel bars penetrate through the steel bar truss. Two ends of the steel beam are respectively lapped on the lower cover plates on two sides of the steel beam. The lower cover plate is in lap joint with the lower flange of the H-shaped steel beam through the lower notch in the lower cover plate, so that the thickness of the whole floor system can be effectively reduced; meanwhile, through the arrangement of the first lap joint steel bars, the normal use load of the floor slab can be effectively transmitted, the formation of a single-span slab is avoided, and the mid-span deflection is effectively reduced; and the joint of the lower cover plate of the composite building can be prevented from cracking.
本发明公开了一种装配式钢‑混凝土组合空心叠合楼盖及其施工方法，属于装配式建筑技术领域。本发明的叠合楼盖包括预制的下盖板、现浇的上盖板以及钢筋桁架，所述下盖板在跨度方向上设有用于搭接在钢梁下翼缘上的下槽口，所述钢梁的腹板上开设有供第一搭接钢筋穿过的穿筋孔，且该第一搭接钢筋穿过对应的穿筋孔后，其两端分别搭接在钢梁两侧的下盖板上。本发明通过下盖板上的下槽口将下盖板搭接在H型钢梁的下翼缘上，可有效减小了整体楼盖厚度；同时，通过第一搭接钢筋的设置，既可有效传递楼板的正常使用荷载，避免形成单跨板，有效减少跨中挠度；还可避免叠合楼下盖板连接处的开裂。
