Construction method of connecting structure of swing item stairway and connecting structure
The invention relates to a construction method of a connecting structure of a swing item stair and the connecting structure. The construction method comprises the steps that shear wall body steel bars are bound; pre-burying a stair beam and slab steel bar connecting piece; pre-burying a stair cross beam steel bar connecting piece; a shear wall body formwork is built, and a shear wall body concrete structure is poured; the shear wall body formwork is dismantled, and the stair beam plate reinforcing steel bar connecting pieces and the stair beam reinforcing steel bar connecting pieces are cleaned out on the shear wall body concrete structure; binding stair beam plate steel bars and stair cross beam steel bars; building an item throwing stair template; casting a throwing stair concrete structure; and the throwing item stair formwork is dismantled. Formwork holing can be avoided, the turnover rate of the formworks is increased, the cost is reduced, and the construction period is shortened; and the problems that poured main reinforcements need to be avoided when a post-embedded reinforcement mode is adopted, the concrete structure is damaged, and time and labor are wasted can be solved.
本申请涉及一种甩项楼梯的连接结构的施工方法及连接结构，施工方法包括：绑扎剪力墙墙身钢筋；预埋楼梯梁板钢筋连接件；预埋楼梯横梁钢筋连接件；搭建剪力墙墙身模板，浇筑剪力墙墙身混凝土结构；拆除所述剪力墙墙身模板，且在所述剪力墙墙身混凝土结构上清理出所述楼梯梁板钢筋连接件和所述楼梯横梁钢筋连接件；绑扎楼梯梁板钢筋和楼梯横梁钢筋；搭建甩项楼梯模板；浇筑甩项楼梯混凝土结构；拆除所述甩项楼梯模板。本申请可以避免模板开洞，提高模板的周转率，降低成本，缩短施工周期；还可以避免采用后植筋形式时需避让已浇筑主筋、破坏混凝土结构、费时费力的问题。
