Precast concrete shear wall joint design and construction method for mechanical sleeve connection
The invention relates to the technical field of prefabricated building construction, in particular to a design and construction method for prefabricated concrete shear wall joints connected through mechanical sleeves, prefabricated shear wall joints are designed, a steel bar sleeve connection scheme is determined based on the joints, and a connection scheme is obtained; the prefabricated shear wall is installed, and the vertical steel bars are mechanically connected based on the connecting scheme; post-pouring rings are installed on the vertical steel bars, then cast-in-place layer steel bars are arranged on the prefabricated slabs, and concrete is poured into the post-pouring rings and the cast-in-place layer steel bars; according to the method, sleeve mechanical connection capable of conducting torque checking within the visual range through vertical steel bars is adopted, and meanwhile, the sleeve mechanical connection is poured into a post-pouring ring beam set according to the industrial standard Technical Regulations for Fabricated Concrete Structures JGJ1. The horizontal seam connection of the shear wall is integral seam connection, and the connection reliability of the prefabricated shear wall is improved.
本发明涉及装配式建筑施工技术领域，具体涉及机械套筒连接的预制混凝土剪力墙节点设计和施工方法，设计预制剪力墙节点，并基于节点确定钢筋套筒连接方案，得到连接方案；安装预制剪力墙，并基于连接方案对竖直钢筋机械连接；对竖直钢筋安装后浇圈，再向预制板布设现浇层钢筋，并对后浇圈和现浇层钢筋浇筑混凝土；对预制剪力墙边缘筑混凝土，该方法通过竖向钢筋在目视范围内可以进行扭矩校核的套筒机械连，同时本发明将套筒机械连接浇筑在行业标准《装配式混凝土结构技术规程》JGJ1要求设置的后浇圈梁中，使得剪力墙的水平缝连接为整体式接缝连接，提高了预制剪力墙连接的可靠性。
