Large-span bent cap prestress formwork supporting construction method
The invention relates to a large-span bent cap prestress formwork supporting construction method, and belongs to the field of bridge building construction. The method comprises pier studs and a bent cap framework, and includes the steps of 1) support point arrangement, 2) bottom formwork platform erection, 3) formwork installation and reinforcement, 4) steel strand introduction and tension force control, 5) concrete pouring to reach the tension strength, and 6) successive disassembly of the bent cap framework and the bottom framework platform. According to the construction method, reserved holes are formed in the pier bridge, supporting rods are placed in the reserved holes to serve as transverse supports, steel pipe column supporting is replaced, the cost is saved, the construction periodis shortened, and the construction efficiency is improved.
本发明涉及一种大跨度盖梁预应力模板支撑施工方法，属于桥梁建筑施工领域，包括墩柱和盖梁模板，1）支撑点设置、2）底模平台搭设、3）模板安装加固、4）传入钢绞线，张拉力控制、5）用混凝土进行浇筑达到张拉强度；6）将盖梁模板和底模平台依次拆除。通过在墩桥处设置预留孔，放置支撑棒，作为横向支撑，替代钢管柱支撑，节约成本，缩短工期，提高施工效率。
