Construction method and formwork supporting structure for pouring circular-arch-shaped roof
The invention provides a construction method and a formwork supporting structure for pouring a circular-arch-shaped roof. The problems of circular-arch-shaped roof construction and formwork structures are solved. The construction method comprises the steps that a supporting system is built, inner formwork back ridges and secondary ridge battens are installed, an inner formwork bottom face plate and an inner formwork are installed, arc faces on the two sides are poured according to a wall body to build an outer formwork, and concrete is poured. The formwork supporting structure comprises an inner formwork back ridge part formed by circular arched I-shaped steel back ridges and the secondary ridge battens, a net rack back ridge supporting part built by steel tubes and an inner formwork part formed by an inner formwork bottom panel and a strip-type wood inner formwork, wherein the secondary ridge battens are fixed to the circular arched I-shaped steel back ridges, the inner formwork bottom panel is fixed to the secondary ridge battens, the strip-type wood inner formwork is fixed to the inner formwork bottom panel, and the arc faces on the two sides are of a formwork structure for wall pouring. The construction method has the beneficial effects that the investment cost of the formwork and the indoor ceiling fair-faced concrete effect are reduced, the construction period is shortened, and the manufacturing time of the special formwork is shortened.
一种浇筑圆拱形屋面的施工方法及模板支撑结构，解决圆拱形屋面施工和模板结构问题，施工方法是：搭建支撑体系、安装内模板背楞和次楞木方、安装内模底面板和内模板、两侧弧面按墙体浇筑搭建外模板、混凝土浇筑。模板支撑结构是：由圆拱形工字钢背楞和次楞木方构成的内模板背楞部分，次楞木方与圆拱形工字钢背楞固定，有钢管搭建的网架背楞支撑部分，由内模底面板和条形木纹内模板构成的内模板部分，内模底面板固定在次楞木方上，条形木纹内模板固定在内模底面板上，两侧弧面为墙体浇筑的模板结构。有益效果是：减少模板的投入费用和室内顶棚清水混凝土效果，缩短施工工期和专用模板的制造时间。
