Large cantilever bent cap lower chord reverse supporting bracket system and construction method thereof
The invention relates to a reverse supporting bracket system for a lower chord of a large cantilever bent cap and a construction method thereof, the system comprises a bearing platform, a steel pipe column, a holding column, a sand box, a distribution beam, a reinforced bailey beam, a bearing beam, a bailey beam reinforcing assembly and a keel bottom die assembly, and the steel pipe column is mounted on an embedded flange plate of the bearing platform; the embracing column comprises transverse channel steel and inclined channel steel; the distribution beam is fixedly arranged on the top surface of the sand box; the reinforced bailey beam comprises a bailey beam body and a reinforced chord member. The bearing beam is mounted at the lower part of the bailey beam; the Bailey beam reinforcing assembly comprises Bailey beam transverse reinforcement and Bailey beam vertical reinforcement; the keel bottom die assembly comprises a bottom die main keel and a secondary keel. The large cantilever and the bailey beam lower chord member are reversely supported and combined, stress is reasonable, safety and reliability are achieved, the problems that a large cantilever bent cap is small in construction occupied space and insufficient in under-bridge clearance can be solved, and cast-in-place concrete construction of the cantilever bent cap on a support system can be rapidly and economically achieved.
本发明涉及一种大悬臂盖梁下弦杆反向支撑支架体系及其施工方法，该体系包括承台、钢管柱、抱柱、砂箱、分配梁、加强型贝雷梁、承重梁、贝雷梁加固组件和龙骨底模组件，钢管柱安装在承台的预埋法兰盘上；抱柱包括横向槽钢和斜向槽钢；砂箱安装在钢管柱顶部，分配梁固定安装在砂箱顶面；加强型贝雷梁包括贝雷梁和加强弦杆；承重梁安装在贝雷梁下部；贝雷梁加固组件包括贝雷梁横向加固和贝雷梁竖向加固；龙骨底模组件包括底模主龙骨、次龙骨。本发明采用大悬臂和贝雷梁下弦杆反向支撑结合，受力合理，安全可靠，可解决大悬臂盖梁施工占地小、桥下净空不足的问题，可快速、经济的实现在支架体系上进行悬臂盖梁的现浇混凝土施工。
