Prefabricated and assembled integral concrete shear wall structure and construction method
The invention discloses a prefabricated and assembled integral concrete shear wall structure and a construction method. The structure comprises a prefabricated shear wall, an ultra-high performance concrete post-cast strip, a bedding layer and a floor slab. The vertical distribution steel bars in the middle of the prefabricated shear wall are configured according to the minimum reinforcement ratio, the vertical distribution steel bars at the bottom of the wall body do not stretch out of the prefabricated wall body and are disconnected with horizontal joints of a lower floor slab, and the area of longitudinal bars in the range of edge components of the shear wall is increased according to the bending resistance equal-strength principle; the longitudinal bars of the edge members of the upper and lower layers of shear walls are mutually anchored and connected in a staggered manner through ultra-high performance concrete. By reinforcing the edge longitudinal bars of the prefabricated shear wall, the vertically-distributed steel bars in the middle of the shear wall are not connected, connection of the edge member longitudinal bars of the upper-layer shear wall and the lower-layer shear wall is achieved through the good anchoring performance of the steel bars and the ultra-high-performance concrete, construction is convenient, and the construction and installation efficiency is high.
本申请公开了一种预制装配整体式混凝土剪力墙结构及施工方法，所述结构包括预制剪力墙、超高性能混凝土后浇带、坐浆层和楼板。预制剪力墙中部竖向分布钢筋采用最小配筋率进行配置，并且墙体底部竖向分布钢筋不伸出预制墙体，在与下层楼板的水平接缝处断开连接，剪力墙边缘构件范围内纵筋按抗弯等强的原则加大面积，上下层剪力墙边缘构件的纵筋通过超高性能混凝土错位互锚连接。本申请通过增强预制剪力墙的边缘纵筋，实现剪力墙中部竖向分布钢筋不连接，利用钢筋与超高性能混凝土的良好锚固性能实现上下层剪力墙的边缘构件纵筋的连接，施工方便，施工安装效率高。
