On-site formwork-erecting-free longitudinal and transverse wall connecting structure for superposed shear wall and construction process
The invention discloses an on-site formwork-erecting-free longitudinal and transverse wall connecting structure for superposed shear walls and a construction process. Prefabricated concrete wall plates of prefabricated walls extend towards a joint position to form a closed cavity, a vertical post-pouring section is arranged in the closed cavity, horizontal connecting steel bars are arranged in a penetrating mode in advance, the horizontal connecting steel bars in the cavity are integrally moved to a designed position by means of a special shifting rod, and post-pouring concrete is poured to realize connection of the longitudinal and transverse prefabricated walls. According to the on-site formwork-erecting-free longitudinal and transverse wall connecting structure, the construction on-siteformwork-erecting-free of the longitudinal and transverse prefabricated wall connecting joint position vertical post-pouring section of the composite shear wall structure can be achieved, the site construction efficiency can be obviously improved, meanwhile, an edge component area with the stirrup restraining effect basically equal to that of the cast-in-place shear wall can be formed at the connecting joint position, the length of the horizontal connecting steel bars stretching into the cavity of the prefabricated walls can meet the lap joint force transmission requirement, the connecting integrity is high, and the structure is suitable for a high-layer superposed shear wall structure with the high seismic fortification requirement.
用于叠合剪力墙的现场免支模纵横墙连接构造及施工工艺，预制墙预制混凝土壁板向节点位置延伸形成封闭空腔，在封闭空腔内设置竖向后浇段、预先穿设水平连接钢筋，借助专用移位杆将空腔内水平连接钢筋整体移动到设计位置，浇筑后浇混凝土实现纵横向预制墙的连接。本发明可实现叠合剪力墙结构纵横向预制墙连接节点位置竖向后浇段施工现场免支模，可明显提高现场施工效率；同时可在连接节点位置形成箍筋约束效果基本与现浇剪力墙等同的边缘构件区域，水平连接钢筋伸入预制墙空腔内的长度可满足搭接传力要求，连接整体性强，适用于抗震设防要求较高的高层叠合剪力墙结构。
