Cast-in-place concrete beam slab stair totally-closed formwork reinforcing method
The invention provides a cast-in-place concrete beam slab stair totally-closed formwork reinforcing method. By changing the formwork erecting mode of stair steps, the stair step semi-closed formwork machining mode in the traditional technology is innovatively changed into the stair step totally-closed formwork reinforcing construction mode, and the stair step is used as a special-shaped shear wall to be reinforced. According to the cast-in-place concrete beam slab stair totally-closed formwork reinforcing method, the problems caused by the stair steps after formwork removal due to the fact that a traditional cast-in-place stair concrete beam slab stair formwork is erected can be effectively solved, the construction efficiency is greatly reduced, and unnecessary labor cost and repairing cost are caused; and meanwhile, specially-assigned persons do not need to be arranged for finished product protection after pouring is completed, a gap is reserved during splicing of a stair step top face formwork and a side face formwork, after stair concrete is poured, stair concrete is vibrated through a vibrating rod, stair concrete grout overflows from the gap, it is guaranteed that the formwork is filled with the stair concrete in place, and the quality problems of honeycombs, pitted surfaces, holes and the like in local stepping parts are solved.
本发明提供了一种现浇混凝土梁板式楼梯全封闭式模板加固方法，通过改变楼梯踏步的模板支设形式，将传统工艺中楼梯踏步半封闭式模板加工方式，创新改为楼梯踏步全封闭式模板加固施工方式，将楼梯踏步看作为异形剪力墙进行加固，该方法能够有效避免传统现浇楼梯混凝土梁板式楼梯模板支设导致的拆模后楼梯踏步所产生的问题，施工效率大大降低，造成不必要的人工费用与修补费用，同时浇筑完成收光抹平后无需安排专人进行成品保护，通过楼梯踏步顶面模板与侧面模板拼接时预留缝隙，在楼梯混凝土浇筑后，通过振捣棒振捣楼梯混凝土，使楼梯混凝土浆从缝隙处溢出，来保证模板内楼梯混凝土填充到位，预防局部踏步部位出现蜂窝、麻面、孔洞等质量问题。
