Cantilever bridge side span formwork system and construction method thereof
The invention discloses a cantilever bridge side span formwork system and a construction method thereof, and belongs to the technical field of bridge construction. An embedded steel plate is arrangedat the top of a side span buttress, supporting frames are welded and installed on the embedded steel plate, reinforcing supports are arranged between the adjacent supporting frames, temporary fixing piers, top longitudinal beams, support longitudinal beams, rear upper transverse beams, rear lower transverse beams and front transverse beams are installed between the supporting frames and a poured bridge section, and transverse distribution beams are arranged on the bottom longitudinal beams. The bottom die is mainly laid on the transverse distribution beam, the other part is paved between the support frame and the permanent support and supported by the inner temporary support; the outer die support is arranged on the support longitudinal beam; the flange bottom die and the outer side die are arranged on the outer die support and fixed through the opposite-pull rods respectively, the inner die is installed on the bottom die, the side span buttress top supporting frame and the poured bridge section are used as a gravity supporting structure for cantilever bridge side span closure section construction, the hoisting workload is reduced, and therefore the construction period is shortened, and the construction cost is reduced.
本发明公开了悬臂桥边跨支模体系及其施工方法，属于桥梁建筑技术领域，预埋钢板设置在边跨支墩顶部，在预埋钢板上焊接安装支撑架，相邻支撑架之间设置加强撑，在支撑架和已浇筑桥段间安装临时固定墩、顶部纵梁、支架纵梁、后上横梁、后下横梁和前横梁，在底部纵梁上设置横向分配梁；底模主要铺设在横向分配梁上，另一部分铺设在支撑架和永久支座之间，由内临时支座支撑，外模支架设在支架纵梁上，翼缘底模和外侧模设置在外模支架上，分别通过对拉拉杆固定，底模上安装有内模，利用边跨支墩顶部支撑架和已浇筑桥段作为悬臂桥边跨合拢段施工的重力支撑结构，减少吊装工作量，从而减少了施工工期和成本。
