Fabricated permanent and temporary combined stair step template and stair construction method
The invention belongs to the technical field of building construction, and discloses an assembly type permanent and temporary combined stair step formwork and a stair construction method.The step formwork comprises internal corner angle steel, external corner angle steel, anchor bars and step side formworks; the external corner angle steel and the internal corner angle steel are arranged in parallel up and down and are respectively used as an external corner protection corner and an internal corner protection corner of the step; a plurality of anchor bars are welded on two wing plates of the internal corner angle steel and the external corner angle steel along the 45-degree direction, and are anchored with the stair bottom steel bars; the top and the bottom of the stepping side formwork are fixedly connected with the external corner angle steel and the internal corner angle steel through a plurality of self-tapping screws respectively. The manufactured step formwork is simple in manufacturing process, can serve as a temporary fixing formwork in the construction process, can permanently protect the internal corner and the external corner of the step after concrete is cast in place, and improves the structural strength of the step. Meanwhile, integrated prefabrication and assembly production can be achieved, a traditional step formwork process of wood formwork fragmentation and assembly can be replaced, the construction precision is high, and supporting is stable.
本发明属于建筑施工技术领域，公开了一种装配式永临结合楼梯踏步模板及楼梯的施工方法，其中的所述踏步模板包括阴角角钢、阳角角钢、锚筋和踏步侧模；阳角角钢和阴角角钢上下平行设置，分别作为踏步的阳角护角和阴角护角；多根锚筋沿45°方向焊接在阴角角钢和阳角角钢的两翼板上，且与楼梯底部钢筋锚固；踏步侧模设于阴角角钢上，其顶部和底部均分别通过多个自攻螺丝与阳角角钢和阴角角钢固定连接。本发明制成的踏步模板制作工艺简单，既能在施工过程中充当临时固定模板，又能在现浇混凝土后对踏步的阴角和阳角进行永久保护，并加强踏步的结构强度。同时，能实现一体化预制拼装生产，可替代木模碎拼的传统踏步模板工艺，其施工精度高，支撑稳固。
