Prefabricated shear wall vertical connection structure for indirect lap joint of intensive reinforcing bars and construction method
The invention discloses a prefabricated shear wall vertical connection structure for indirect lap joint of intensive reinforcing bars and a construction method of the prefabricated shear wall vertical connection structure. Reserved hole channels are formed in wall cores of the upper ends and the lower ends of the prefabricated shear walls, a double-layer metal corrugated pipe telescopic structure is arranged in the reserved hole channel in the upper end of the lower-layer prefabricated shear wall and comprises an inner pipe and an outer pipe, and in the manufacturing, transporting and hoisting stages of the prefabricated shear walls, the inner pipe can be hidden in the outer pipe, and the outer pipe can be hidden in the outer pipe. When a concrete laminated layer of the laminated floor slab is poured, the inner pipe can rotationally extend to a position higher than the elevation of the surface of the laminated floor slab to form a floor slab through hole, and meanwhile, concrete is prevented from falling into the reserved hole channel when the concrete laminated layer of the laminated floor slab is poured; a communicating cavity is formed by the lower end reserved hole channel of the upper-layer prefabricated shear wall, the floor through hole and the upper end reserved hole channel of the lower-layer prefabricated shear wall, and connecting steel bars are inserted into the communicating cavity which is filled with grouting materials.
本发明公开了一种集约配筋间接搭接的预制剪力墙竖向连接构造及其施工方法。预制剪力墙的上下两端墙芯处设有预留孔道，下层预制剪力墙的上端预留孔道内设置双层金属波纹管伸缩型结构，双层金属波纹管伸缩型结构包括内管和外管，在预制剪力墙的制作、运输和吊装阶段，内管可藏于外管中，在浇筑叠合楼板的混凝土叠合层时，内管可旋伸至高于叠合楼板面标高处形成楼板贯通孔，同时防止浇筑叠合楼板的混凝土叠合层时混凝土落入预留孔道；上层预制剪力墙的下端预留孔道、楼板贯通孔以及下层预制剪力墙的上端预留孔道构成连通腔，连通腔内插置连接钢筋并填充灌浆料。
