The invention relates to a resettable local post-pouring connection concrete shear wall and a connection method, and belongs to the technical field of fabricated building construction. The precast concrete wall body and the concrete foundation beam are both of independent structures; the unbonded prestressed tendons penetrate through the prefabricated concrete wall body and the concrete foundation beam; a part of concrete wall body vertical steel bars pre-embedded in the prefabricated concrete wall body extend to the groove part; concrete foundation beam vertical steel bars are pre-buried in the concrete foundation beam; the vertical steel bars of the concrete foundation beam extend to a groove part of a prefabricated concrete wall body on the concrete foundation beam; the concrete wall vertical steel bars and the concrete foundation beam vertical steel bars are connected through vertical connecting mechanisms. And ultra-high performance concrete is poured after the groove part of the concrete wall body is prefabricated. The method is based on a post-pouring section formed by concrete wall body vertical steel bars, concrete foundation beam vertical steel bars and ultra-high performance concrete; and the ultra-high performance concrete and the vertical ribs are combined to form a post-pouring section, so that the bearing capacity and ductility of the whole structure are improved.
本发明涉及一种可复位的局部后浇连接混凝土剪力墙及连接方法，属于装配式建筑施工技术领域。预制混凝土墙体与混凝土基础梁均为独立结构；无粘结预应力筋贯穿预制混凝土墙体与混凝土基础梁；预制混凝土墙体内预埋的部分混凝土墙体竖向钢筋延伸至凹槽部；混凝土基础梁内预埋混凝土基础梁竖向钢筋；混凝土基础梁竖向钢筋延伸至混凝土基础梁上预制混凝土墙体的凹槽部；混凝土墙体竖向钢筋与混凝土基础梁竖向钢筋之间采用竖向连接机构相互连接；预制混凝土墙体的凹槽部后浇筑超高性能混凝土。本发明基于混凝土墙体竖向钢筋，混凝土基础梁竖向钢筋及超高性能混凝土形成的后浇段；超高性能混凝土与竖向筋一起合成后浇段，这提升整体结构的承载力和延性。
