Prefabricated hollow superimposed shear wall with vertical reinforcing steel bars free of extending out and shaped pipeline for hole forming
The invention discloses a prefabricated hollow superimposed shear wall with vertical reinforcing steel bars free of extending out and a shaped pipeline for hole forming. The shaped pipeline is used for forming vertical holes so as to realize the lap joint of vertical reinforcing steel bars and vertical distribution reinforcing steel bars of edge members of an upper wall and a lower wall in the overall shear wall structure; the vertical holes penetrate the height direction of the wall; the shaped pipeline is used for hole forming; and special hole-forming equipment is not needed. The vertical reinforcing steel bars of the edge members do not extend out of the top surface and bottom surface of the prefabricated wall; vertical additional connecting reinforcing steel bars II are laid at the floor level in the vertical holes of the edge members; and after concrete is poured into the vertical holes, the vertical reinforcing steel bars, no extending out of the upper prefabricated wall and thelower prefabricated wall, of the edge members are in lap joint with the additional connecting reinforcing steel bars to realize the continuity of the vertical reinforcing steel bars of the edge members of the upper prefabricated wall and the lower prefabricated wall. The vertical distribution reinforcing steel bars are also in lap joint by adopting the additional connecting reinforcing steel bars. The vertical reinforcing steel bars do not extend out of the prefabricated wall; no holes are formed in side forms in the prefabricated wall production stage; the standardization and generalizationof molds can be achieved; and the cost control and the finished product protection are facilitated.
本发明公开了一种竖向钢筋不出筋及定型管道成孔的预制空心叠合剪力墙，采用定型管道形成竖向孔以实现整体剪力墙结构中上下层墙体边缘构件竖向钢筋、竖向分布钢筋的搭接连接，竖向孔贯通墙体高度方向、采用定型管道成孔，无需专用成孔设备。边缘构件竖向钢筋不伸出预制墙顶面及底面，在边缘构件竖向孔内楼面标高处布设竖向的附加连接钢筋二，浇筑竖向孔内后浇混凝土后，上下层预制墙未伸出的边缘构件竖向钢筋分别与附加连接钢筋搭接连接，实现上下层预制墙边缘构件竖向钢筋的连续性。竖向分布钢筋也采用附加连接钢筋搭接连接，预制墙不伸出竖向钢筋，预制墙生产阶段边模不开孔，可实现模具标准化、通用化，有利于成本控制及成品保护。
