Positioning method for prefabricated finished stair end embedded steel bars

The invention relates to the field of building construction, in particular to a positioning method for prefabricated finished stair end embedded steel bars. Comprising a square steel tube (1) and a steel sleeve (2), the square steel tube (1) and the steel sleeve (2) are in full-length welding connection according to the drawing size to ensure that the position of the steel sleeve (2) is always unchanged, the steel sleeve (2) and the square steel tube (1) are in full-length welding according to the drawing size, and embedded steel bar bolts are inserted in the construction process to ensure that the positions of the embedded steel bar bolts are always unchanged; according to the method, the position of the embedded steel bar bolt at the end of the stair is limited through matching of the square steel pipe and the steel sleeve, and therefore the assembly type finished stair end embedded steel bar bolt positioning device for building construction is high in working efficiency. 本发明涉及建筑施工领域，具体是一种装配式成品楼梯端部预埋钢筋的定位方法
