Cast-in-place concrete spiral stair formwork erecting method and formwork system
The invention discloses a cast-in-place concrete spiral stair formwork erecting method and a formwork system.The cast-in-place concrete spiral stair formwork erecting method comprises the following steps that S1, step front edge lines serve as datum lines for pay-off positioning of a spiral stair, the positions of the step front edge lines of all stages of the spiral stair are firstly positioned, and pay-off positioning of the step front edge lines is completed; s2, secondly, the position of a bottom plate generatrix of the spiral stair is positioned, and an inner peripheral vertical rod, an outer peripheral vertical rod and a radial horizontal rod are erected; s3, stabilizing rods are connected between the inner peripheral vertical rods and between the outer peripheral vertical rods; and S4, finally, stair formworks are laid on the radial horizontal rods. Through the disclosure of the invention, an accurate, reliable, simple, convenient and feasible paying-off positioning and formwork erecting method and a formwork system which is simple and clear in stress and safe and reliable in structure are provided, the construction quality of the cast-in-place concrete spiral stairway is improved, the construction difficulty is reduced, and the construction period is shortened.
本发明公开了一种现浇混凝土螺旋楼梯支模方法及模板系统，包括以下步骤：S1，以踏步前缘线作为螺旋楼梯放线定位的基准线，首先定位螺旋楼梯各级踏步前缘线的位置，完成各踏步前缘线的放线定位；S2，其次，定位螺旋楼梯的底板母线位置并支设内周立杆、外周立杆以及径向水平杆；S3，在内周立杆之间与外周立杆之间分别连接稳定杆；S4，最后，在径向水平杆上铺设楼梯模板。通过本发明的公开，以提供一种精确、可靠、简便、易行的放线定位和支模方法，以及一种受力简单、明确，结构安全、可靠的模板系统，提高了现浇混凝土螺旋楼梯的施工质量、降低施工难度、减少施工工期。
