Cast-in-place stair formwork system and construction method
The invention relates to a cast-in-place stair formwork system and a construction method. The cast-in-place stair formwork system comprises a shear-wall-free stair formwork system, a shear-wall-provided stair formwork system and a bottom formwork supporting system. The shear-wall-free stair formwork system comprises a bottom formwork, side formworks, reinforcing wooden wedges, brace plates, triangular bottom blocks, reinforcing side formworks and two-way pull rods. The step formwork has the beneficial effects that the step formworks are connected into a whole through the brace plates, and the stability of the step formwork in the concrete pouring process is improved; the reinforcing side formworks and the quick-release lock pins are installed outside the side formworks and can abut against the side formworks after being oppositely pulled and screwed, and lateral deformation of the side formworks in the concrete pouring process is further prevented; a support and a one-way pull rod are ingeniously installed through reserved screw holes of the shear wall, the stepping formwork is suspended and fixed, and the side formwork is reinforced to prevent lateral displacement in the pouring process; the stair formwork supporting system can be suitable for stair formwork supporting construction of different heights and sizes, and the stability and reliability of the whole stair formwork supporting system are guaranteed.
本发明涉及一种现浇楼梯支模体系及施工方法，包括以下步骤：包括无剪力墙楼梯模板体系、有剪力墙楼梯模板体系和底模支撑体系；所述无剪力墙楼梯模板体系包括底模板、侧模板、加强木楔、拉条板、三角底块、加固侧模板和双向拉杆。本发明的有益效果是：通过拉条板将各级踏步模板连接为一个整体，提高了混凝土浇筑过程中踏步模板的稳定性；在侧模板外部安装加固侧模板以及快拆锁销，对拉旋紧后可抵住侧模板，进一步防止其在浇筑混凝土过程中发生侧向变形；巧妙地利用剪力墙预留螺杆孔安装支架和单向拉杆，悬吊固定踏步模板，加固侧模板防止浇筑过程中的侧移；可适用于不同高度和尺寸的楼梯支模施工，保证了整个楼梯支模体系的稳定性和可靠性。
