Straight wall circular arch cast-in-place structure formwork and installation method thereof
The invention relates to a straight wall circular arch cast-in-place structure formwork and a mounting method thereof, the formwork comprises an arc-shaped top formwork structure and a bottom formwork, and further comprises an arc-shaped main beam used for supporting the top formwork, a small beam, a full space supporting frame body used for supporting the arc-shaped main beam, an opposite-pull screw rod and a back ridge used for supporting the top formwork. An adjustable jacking is arranged at the top end of a longitudinal frame of the full space supporting frame body, the arc-shaped main beam comprises arc-shaped profile steel matched with the radian of a circular arch to be poured, right-angle supporting profile steel is arranged at the position, corresponding to the adjustable jacking, of the bottom of the arc-shaped profile steel, and a plurality of positioning baffles used for limiting the small beam are arranged at the top of the arc-shaped profile steel. According to the installation method, the supporting plate of the adjustable jacking can be directly supported on the right-angle supporting profile steel of the arc-shaped main beam, deformation caused by eccentric compression of the adjustable jacking and long-term bending of a component can be avoided, the turnover use frequency and safety of the adjustable jacking and the vertical rod are increased, and the overall stability is good.
本发明涉及一种直墙圆拱现浇结构模板及其安装方法，所述模板包括弧形的顶模板结构及底模板，还包括用于支撑所述顶模板的弧形主梁、小梁、支撑所述弧形主梁的满堂支撑架体、对拉螺杆及支撑所述顶模板的背楞。所述满堂支撑架体的纵架顶端设有可调顶托，所述弧形主梁包括与待浇圆拱弧度相配的弧形型钢，所述弧形型钢的底部对应所述可调顶托的位置设有直角支撑型钢，所述弧形型钢的顶部设有若干用于限位所述小梁的定位挡板。该安装方法可将可调顶托托板直接支承在弧形主梁的直角支撑型钢上，可以避免可调顶托偏心受压，构件长期受弯而导致的变形，增加可调顶托及立杆周转使用次数及安全性，整体稳定性较好。
