Construction method for erecting prefabricated box girder of bent frame steel structure system bridge
The invention discloses a construction method for erecting a prefabricated box girder of a bent steel structure system bridge. The construction method comprises the following steps: S1, erecting an initial girder lifting platform; s2, a gantry crane starting section track foundation is built; s3, erecting a box girder temporary support; s4, mounting a gantry crane; s5, erecting a box girder; s6, carrying out cast-in-place construction on a flange plate between a pier top cross beam and a box girder; s7, the gantry crane retreats to the initial beam lifting platform along the track; according to the construction method, the construction technical problem of erection of the prefabricated girder of the bent frame steel structure system bridge is solved, the construction cost is reduced, the construction efficiency is improved, erection of the prefabricated box girder of the bent frame steel structure system bridge is achieved, the hoop support system is adopted as a non-landing supporting structure, and the construction cost is reduced. The difficulty that under-bridge topographic and geological conditions are not suitable for erecting a floor stand is overcome, and the box girder is erected in a mode of combining two kinds of large hoisting equipment, namely a gantry crane and a truck crane.
一种排架钢构体系桥梁预制箱梁架设施工方法，其步骤为：S1、搭设起始提梁平台；S2、打设龙门吊起始段轨道基础；S3、搭设箱梁临时支架；S4、安装龙门吊；S5、箱梁架设；S6、墩顶横梁和箱梁间翼缘板现浇施工；S7、龙门吊沿轨道退回至起始提梁平台；S8、安装边梁，拆除边梁下方龙门吊轨道基础，本发明解决了排架钢构体系桥梁预制主梁架设的施工技术难题，降低了施工成本，提高了施工效率，实现了排架钢构体系桥梁预制箱梁的架设，采用抱箍支架体系作为不落地支撑结构，克服了桥下地形地质条件不适合搭设落地支架的困难，采用龙门吊和汽车吊两种大型起重设备相结合的方式进行箱梁架设。
