Construction system and construction method of large-section steel box girder
The invention discloses a construction system and a construction method of a large-section steel box girder, the system comprises a plurality of temporary supports and a steel box girder, the temporary supports and piers (32) share to form a bridge support for supporting the steel box girder, and the steel box girder is formed by splicing a plurality of segments (34) in the direction of a bridge. According to the method, the plate units (8) forming the sections (34) are prefabricated, after temporary supports are arranged on site, all the sections (34) are hoisted, bridge welding and coating are conducted after flange plates (55) are installed, and then the temporary supports are dismantled. The method has the advantages of being economical and efficient, rapid fine adjustment can be achieved, and the time for hoisting the double-layer bridge steel box girder through a traditional method is greatly shortened.
本发明公开了一种大截面钢箱梁的施工体系及施工方法，体系包括多个临时支架、钢箱梁，临时支架与桥墩（32）共用构成桥梁支撑用于支撑钢箱梁，钢箱梁由多个节段（34）按桥梁走向拼接构成。方法中预制构成节段（34）的板单元（8），并现场布置临时支架后，吊装各个节段（34），待翼缘板（55）安装完成后进行桥梁焊接和涂装，然后拆除临时支架。本发明具有经济，高效的优势，能够实现快速精调，大大缩短了采用传统方法吊装双层桥钢箱梁的时间。
