Fabricated prefabricated stair and mounting method thereof
The invention discloses an assembly type prefabricated stair installation method which comprises the steps that a stair board is prefabricated, two preformed holes are formed in the first step of the stair board, and two preformed holes are formed in the last step of the stair board; a stair lap joint bracket is arranged on a lower floor slab, two connecting screw rods are pre-buried in the bracket, the pre-buried connecting screw rods need to correspond to the plane positions of two preformed holes in a prefabricated stair plate, the floor slab and the bracket are both of a cast-in-place structure, and pouring is conducted at the same time during construction; prefabricated stair plate lap joint brackets are arranged on a rest platform, and connecting screws arranged in the brackets meet the pre-burying requirement in the brackets. And cast-in-place components are cast in the rest platform and the bracket position at the same time during construction. After the prefabricated stair plates are preliminarily installed, sliding hinges are formed at the lower ends of the stair plates in different treatment modes, and fixed hinges are formed at the lower ends of the stair plates.
本发明公开了一种装配式预制楼梯安装方法，包括预制楼梯板，在楼梯板第一个台阶设置两个预留孔，在最后一个台阶上设置两个预留孔；在下层楼板设置楼梯搭接牛腿，在牛腿中预埋两个连接螺杆，预埋连接螺杆需与在预制楼梯板上的两个预留孔平面位置相对应，楼板与牛腿同为现浇结构，施工时同时浇筑；在休息平台设置预制楼梯板搭接牛腿，牛腿内设置的连接螺杆与牛腿中的预埋要求一致。休息平台及牛腿位现浇构件，施工时同时浇筑。在预制楼梯板初步安装完成后，采用不同的处理方式使楼梯板下端形成形成滑动铰，使楼梯板下端形成形成固定铰。
