Construction method of high-rise cantilever concrete structure and fabricated structure
The invention relates to a construction method of a high-rise cantilever concrete structure and an assembly type structure, and solves the defect that a scaffold needs to be built externally during construction of cantilever concrete structures such as balconies and flower stands on the top of a high-rise building, and the method comprises the following steps: prefabricating exposed concrete cross beams, longitudinal beams and a top plate with connecting pieces and reinforcement cages, and connecting the concrete cross beams and the longitudinal beams into a grid frame; a concrete top plate is installed in the grid frame and cast in place in the reinforcing layer. The structure comprises flower stand supporting columns, prefabricated concrete laminated cross beams, prefabricated concrete laminated longitudinal beams, a prefabricated building concrete top plate and a cast-in-place concrete top plate reinforcing layer. The prefabricated concrete laminated cross beams and the prefabricated concrete laminated longitudinal beams are mutually connected to form a grid frame structure, the prefabricated concrete top plate is in lap joint in the grid frame structure, and the top plate reinforcement cage, the cross beam reinforcement cage and the longitudinal beam reinforcement cage are arranged in the cast-in-place concrete top plate reinforcing layer. The method has the beneficial effects that an external scaffold does not need to be built, the construction is simple, the construction period is short, and the cast-in-place concrete amount is greatly reduced.
一种高层悬挑混凝土结构的施工方法及装配式结构，解决高层楼顶阳台、花架等悬挑混凝土结构施工需要外搭脚手架的不足，方法包括：预制带连接件和钢筋笼裸露混凝土横梁、纵梁和顶板，混凝土横梁和纵梁连接成网格框架，网格框架中安装混凝土顶板，现浇混凝土顶板加强层内。该结构包括：花架支撑柱、预制混凝土叠合横梁、预制混凝土叠合纵梁、预制楼混凝土顶板和现浇混凝土顶板加强层。预制混凝土叠合横梁与预制混凝土叠合纵梁相互连接构成网格框体结构，预制混凝土顶板搭接在网格框体结构中，顶板钢筋笼、横梁钢筋笼和纵梁钢筋笼设置在现浇混凝土顶板加强层内。有益效果是：无需搭建外脚手架、施工简单、施工周期短、混凝土预制件，大大减少现场浇筑混凝土量。
