Laminated shear wall closely-spliced vertical joint structure and construction method
The invention discloses a laminated shear wall closely-spliced vertical joint structure and a construction method. Only a mounting joint with the width of about 20 mm is arranged between adjacent prefabricated walls, a specially designed vertical joint mold is adopted to improve the capacity of a cantilever section at the end part of a prefabricated concrete wallboard of the prefabricated wall forresisting the pressure of a concrete pouring side mold, the distance between a steel bar truss and the side edge of the prefabricated wall is increased, an internal large cavity is formed in the position of the closely-spliced vertical joint, and a horizontally-connected steel bar shaping steel bar cage is arranged in the cavity in a back arranged mode to achieve lap joint of horizontally-distributed steel bars of the prefabricated wall on the two sides of the vertical joint. According to the construction method, closely-spliced construction of the vertical joint of the laminated shear wall can be achieved, the vertical joint horizontal connecting steel bars are shaped steel bar cages produced industrially, the mold is a shaped universal mold, the standardized operation degree of steel bar penetrating and mold supporting in site construction of vertical joint is high, the site construction efficiency can be improved, the construction quality can be improved, meanwhile, the construction cost can be reduced through standardization and universalization.
本发明公开了一种叠合剪力墙密拼竖向接缝构造及施工方法，相邻预制墙间仅设置宽度为20mm左右的安装缝，采用专门设计的竖向接缝模具提高预制墙预制混凝土壁板端部悬臂段抵抗混凝土浇筑侧模压力的能力，加大钢筋桁架距预制墙侧边的距离，在密拼竖向接缝位置形成内部大空腔，在空腔内后置水平连接钢筋定型钢筋笼实现竖向接缝两侧预制墙水平分布钢筋的搭接连接。本发明可实现叠合剪力墙竖向接缝的密拼施工，且竖向接缝水平连接钢筋采用工业化生产的定型钢筋笼，模具采用定型化通用模具，竖向接缝现场施工钢筋穿设、模具支设标准化作业程度高，可提高现场施工效率、改善建造品质，同时可通过标准化、通用化降低建造成本。
