Continuous rigid frame side span cast-in-place section formwork supporting system
The invention relates to the technical field of bridge construction, in particular to a continuous rigid frame side span cast-in-place section formwork supporting system which comprises a rhombic truss fixedly arranged at the top of a side span. The bottom longitudinal beams are arranged at the bottom of the side span side by side at intervals in the length direction of the side span, extend towards the bent cap and are lapped at the top of the bent cap through free ends; the bottom cross beam is horizontally arranged below the bottom longitudinal beam and is connected with the rhombic truss through a front hanging belt vertically penetrating through the bottom longitudinal beam; the bottom die is arranged above the bottom longitudinal beam, and the top of the bottom die and the bottom of the side span are located on the same plane. And the outer mold is arranged above the bottom mold and used for limiting the outer contour of the cast-in-place section. According to the system, a bracket supporting scheme is omitted, pier column bending caused by the fact that a cast-in-place section exerts overlarge eccentric load on the capping beam pier column in the construction process is avoided, eccentric bending moment is avoided, the use safety of the pier column is guaranteed, meanwhile, due to the fact that bracket supporting is not needed, bracket pre-pressing and other procedures are omitted, construction safety is facilitated, and construction efficiency is improved.
本发明涉及桥梁施工技术领域，具体涉及一种连续刚构边跨现浇段模板支撑系统，其包括:固定式设置在边跨顶部的菱形衍架；沿边跨长度方向间隔并列的设置在边跨底部的底纵梁，底纵梁向盖梁方向延伸，并通过自由端搭在盖梁顶部；底横梁水平设置在底纵梁下方，并通过竖直贯穿底纵梁的前吊带与菱形衍架连接；底模设置在底纵梁上方，并且底模顶部与边跨底部位于同一平面；外模，外模设置在底模上方，用于限定现浇段外轮廓。该系统取消了托架支撑方案，避免现浇段在施工中对盖梁墩柱施加过大偏心荷载造成墩柱受弯，避免偏心弯矩的产生，从而保证了墩柱的使用安全，同时由于需无托架支撑，因此省略托架预压等工序，利于施工安全并提高施工效率。
