Fully-prefabricated flat slab system connected through prestress and construction method of fully-prefabricated flat slab system
The invention provides a fully-prefabricated flat slab system connected through prestress and a construction method of the fully-prefabricated flat slab system. The fully-prefabricated flat slab system comprises a fully-prefabricated floor slab and a prefabricated column supported on the lower surface of the fully-prefabricated floor slab. Column longitudinal bars extend out of the top faces of the prefabricated columns, and column top brackets are arranged on the tops of the prefabricated columns. An anchoring screw extending outwards is arranged on the top surface of the column top bracket; prestressed reinforcements are arranged at the upper part of the fully-prefabricated floor; a pre-embedded metal corrugated pipe is arranged in the middle of the fully-prefabricated floor slab, and screw through holes vertically penetrating in the thickness direction of the fully-prefabricated floor slab are formed in the periphery of the pre-embedded metal corrugated pipe. Prestressed ducts are formed in the four edges of the fully-prefabricated floor slab; column longitudinal bars on the top faces of the prefabricated columns are connected with the embedded metal corrugated pipes in an inserted mode and anchored through grouting. The anchoring screw rod is connected with the screw rod through hole in an inserting manner and is fixed through a nut and a gasket; the prestressed tendons are arranged in the prestressed hole channels of the two fully-prefabricated floor slabs in a penetrating mode. The invention can solve the technical problems of complicated mounting and dismounting work, large wet work workload and large labor demand of the flat slab construction site support template.
本发明提供一种预应力连接的全预制无梁楼盖板体系及其施工方法，包括全预制楼板和支撑在全预制楼板下表面的预制柱；预制柱顶面外伸柱纵筋，预制柱顶部设有柱顶牛腿；柱顶牛腿顶面设有外伸的锚固螺杆；全预制楼板上部设置预应力钢筋；全预制楼板中部设置预埋金属波纹管，预埋金属波纹管的外周设置沿全预制楼板厚度方向竖直贯通的螺杆通孔；全预制楼板的四条边均设置预应力孔道；预制柱顶面的柱纵筋与预埋金属波纹管插接连接，并通过灌浆锚固；锚固螺杆与螺杆通孔插接连接并通过螺母和垫片固定；预应力筋穿设在两块全预制楼板的预应力孔道中。本发明能够解决无梁楼盖施工现场支架模板安拆工作繁杂、湿作业工作量大和劳动力需求大的技术问题。
