Abstract
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。
The invention discloses a side span formwork system of a cantilever bridge and a construction method thereof, and belongs to the technical field of bridge construction. Pre-embedded steel plates are arranged on the top of side span buttresses, and support frames are welded and installed on the pre-embedded steel plates. Strengthen the bracing, install temporary fixed piers, top longitudinal beams, support longitudinal beams, rear upper beams, rear lower beams and front beams between the support frame and the poured bridge section, and set up a horizontal distribution beam on the bottom longitudinal beam; the bottom formwork is mainly laid On the lateral distribution beam, the other part is laid between the support frame and the permanent support, supported by the inner temporary support, the outer mold bracket is set on the support longitudinal beam, and the flange bottom mold and the outer mold are set on the outer mold support, respectively. By fixing the tie rods, the bottom mold is installed with an inner mold, and the top support frame of the side span pier and the poured bridge section are used as the gravity support structure for the construction of the side span closing section of the cantilever bridge, which reduces the hoisting workload and thus reduces the construction period. and cost.
