Laminated shear wall integral horizontal joint and construction method
The invention discloses a laminated shear wall integral horizontal joint and a construction method. The laminated shear wall integral horizontal joint comprises a lower-layer laminated shear wall, an upper-layer laminated shear wall and a concrete post-cast lap joint area, and extrusion sleeves are arranged in the concrete post-cast lap joint area; the horizontal joint formed by the lower-layer laminated shear wall and the upper-layer laminated shear wall is located in the concrete post-cast lap joint area, lower-layer laminated shear wall vertical load-bearing steel bars are arranged in the lower-layer laminated shear wall, upper-layer laminated shear wall vertical load-bearing steel bars are arranged in the upper-layer laminated shear wall, the lower-layer laminated shear wall vertical load-bearing steel bars and the upper-layer laminated shear wall vertical load-bearing steel bars at the horizontal joint are exposed, and the exposed upper-layer laminated shear wall vertical load-bearing steel bars and the exposed lower-layer laminated shear wall vertical load-bearing steel bars are in butt joint at the horizontal joint through the extrusion sleeves. Cooperation of post-cast concrete and post-cast concrete in a prefabricated wall panel cavity is achieved, the coordinating deformation capacity of the post-cast concrete and the post-cast concrete in the prefabricated wall panel cavity is improved, and the integrity of total cross-section stress of the horizontal joint at the bottom of the laminated shear wall is guaranteed.
本发明公开了一种叠合剪力墙整体式水平接缝及施工方法，包括下层叠合剪力墙、上层叠合剪力墙和混凝土后浇的搭接区域，混凝土后浇的搭接区域内设有挤压套筒；由下层叠合剪力墙与上层叠合剪力墙形成的水平接缝位于所述混凝土后浇的搭接区域，下层叠合剪力墙内设有下层叠合剪力墙竖向受力钢筋，上层叠合剪力墙内设置上层叠合剪力墙竖向受力钢筋，该水平接缝处的下层叠合剪力墙竖向受力钢筋与上层叠合剪力墙竖向受力钢筋均外露，外露的上、下层叠合剪力墙竖向受力钢筋在水平接缝处采用挤压套筒对接连接。本发明实现了后浇混凝土与预制墙板空腔中的后浇混凝土的共同工作，提高了二者的协调变形能力，保证了叠合剪力墙底部水平接缝全截面受力的整体性。
