Suspension type formwork support of water area concrete rigid frame bridge and construction method of suspension type formwork support
The water area concrete rigid frame bridge suspension type formwork support comprises a plurality of steel pipe columns, the steel pipe columns are arranged at the top of a bridge pier column, a cast-in-place box beam is arranged at the top of the bridge pier column, a box beam bottom die is arranged at the bottom of the cast-in-place box beam, saddle weights are arranged at the two ends of the top of the box beam bottom die, and the saddle weights are located on the left side and the right side of the cast-in-place box beam. A plurality of suspension frames are arranged at the bottom of the box girder bottom die, guardrails are connected to the front ends and the rear ends of the tops of the suspension frames and located on the front sides and the rear sides of the cast-in-place box girders, the steel pipe columns are connected with the suspension frames through inhaul cables, and transverse supports are connected between the adjacent steel pipe columns on the front side and the rear side. The structure is simple, mounting and dismounting are convenient and fast, the field welding amount is small, water surface operation is little, the construction period is short, and the construction safety of workers is high; the support is of a suspension type structure, the steel consumption is small, except the first steel pipe column, other parts can be repeatedly used, and traffic passing of a road below the cantilever is not affected; the support is wide in applicability, high in turnover utilization rate and good in economical efficiency.
本发明是一种水域混凝土刚构桥悬吊式模板支架及其施工方法，包括若干钢管柱，钢管柱设于桥梁墩柱顶部，桥梁墩柱顶部设有现浇箱梁，现浇箱梁底部设有箱梁底模，箱梁底模顶部两端设有压重块，压重块位于现浇箱梁左右两侧，箱梁底模底部设有若干悬吊架，悬吊架顶部前后两端连接有护栏，护栏位于现浇箱梁前后两侧，钢管柱和悬吊架通过拉索连接，前后侧相邻的钢管柱之间连接有横向支撑。本发明结构结构简单，安拆方便快捷，现场焊接量小，水面作业少，施工周期短，工人施工安全性高；支架为悬吊式结构，用钢量小，且除第一钢管柱以外，其余部分均可重复利用，不影响悬臂下方道路的交通通行；适用性广，支架周转利用率高，经济性好。
