Self-supporting type double-faced laminated shear wall and construction method
The invention provides a self-supporting type double-faced laminated shear wall and a construction method. The self-supporting type double-faced laminated shear wall comprises each laminated shear wall body, wherein each laminated shear wall body comprises two prefabricated wall bodies which are oppositely arranged in parallel at an interval, a vertical reinforcing steel bar penetrates through each prefabricated wall body, the extension part of each vertical reinforcing steel bar extends out of each prefabricated wall body, and the extension part is in lap joint with a ground beam or a pre-embedded vertical reinforcing steel bar of a lower-layer shear wall; the vertical reinforcing steel bars extending out of wall columns suspend the wall body, reinforcing steel bar binding or UHPC short lap joint is facilitated, the effective height of the section of the double-face laminated shear wall is increased, and the structural anti-seismic performance is improved. The prefabricated shear wall structure connected through a horizontal joint is high in assembly rate and easy to construct, long-time operation of large hoisting equipment is not needed, only inclined struts need to be adopted for fixing, the construction period can be greatly shortened, and the construction efficiency can be improved.
本发明提供了一种自承式双面叠合剪力墙及施工方法，包括：各幅叠合剪力墙体，每幅叠合剪力墙体包括：相对平行间隔设置的两块预制墙体，每块预制墙体内贯通有竖向钢筋，所述竖向钢筋的延伸部延伸到每块预制墙体外，所述延伸部与地梁或下层剪力墙的预埋竖向钢筋搭接。外伸出墙肢的竖向钢筋将墙体悬空，方便钢筋绑扎或UHPC短搭接，增大双面叠合剪力墙截面有效高度，提高结构抗震性能。通过该发明的水平节点连接的预制剪力墙结构装配率高，施工简单，无需大型吊装设备长时间作业，只需采用斜撑固定，能够极大减小施工周期，提高施工效率。
