Fully-prefabricated beam-slab integrated floor system and construction method thereof
The invention discloses a fully-prefabricated beam-slab integrated floor system and a construction method thereof. The floor system comprises fully-prefabricated beam-slab units, prefabricated laminated frame beams and stand columns. The stand columns are distributed in an array mode, the prefabricated laminated frame beams are erected between the adjacent stand columns, and flange bearing pieces are arranged on the side walls of the prefabricated laminated frame beams. The precast beam plate unit comprises a reinforced concrete plate and a flange, and the flange is erected on the beam plate bearing piece or the flange bearing piece; annular steel bars are arranged at the ends of the prefabricated beam and slab units. The prefabricated superposed frame beam is provided with a low-position opening hoop and a high-position opening hoop; the low-position opening hoop is matched with a cap steel bar for the beam; the annular steel bars and the high-position opening hoops are distributed in a staggered mode. Concrete is poured on site at each joint; the construction method comprises the steps that the stand columns are sequentially arranged, the composite frame beams are prefabricated, the full-prefabricated beam and slab units are sequentially prefabricated, and finally concrete is poured at the joints. A laminated slab of an existing beam-slab integrated unit is replaced with the full-prefabricated slab, and due to the fact that the rigidity is increased, production and installation of the beam-slab integrated unit with the larger width can be achieved; meanwhile, the construction cost is low.
本发明为一种全预制梁板一体化楼盖及其施工方法，楼盖包括全预制梁板单元、预制叠合框架梁以及立柱；立柱阵列分布，预制叠合框架梁架设在相邻立柱之间且预制叠合框架梁侧壁设有凸缘承托件；预制梁板单元包括钢筋混凝土板和凸缘，凸缘架设在梁板承托件或凸缘承托件上；预制梁板单元端部设有环形钢筋；预制叠合框架梁设有低位以及高位开口箍；低位开口箍配合梁用帽盖钢筋；环形钢筋和高位开口箍呈错位分布；各连接处现场浇筑混凝土；施工方法为依序布设立柱、预制叠合框架梁、全预制梁板单元，最后在连接处浇筑混凝土。本发明将现有梁板一体化单元的叠合板替换为全预制板，由于刚度增大，可实现更大宽度梁板一体化单元生产和安装；同时建造成本低。
