Steel box girder module manufacturing method

Abstract

The application provides a steel box girder module manufacturing method, S1, according to the preset size of a bridge, laying a steel girder box jig on site; S2, laying a prefabricated bottom plate on the steel girder box jig; S3, connecting two adjacent bottom plates through a fixing plate; S4, fixing a web plate and a cross plate inside the bottom plate to complete the manufacturing of a steel box girder body; and S5, cutting the fixing plate in the steel box girder body to divide it into several steel box girder modules. The steel box girder module manufacturing method has less site limitation, is high in flexibility, can be adjusted at any time according to the construction condition, and is convenient to assemble and disassemble the steel girder box jig, can be repeatedly used for many times, is convenient for construction, greatly saves materials and labor, reduces the manufacturing workload of the steel girder box jig, saves the project cost, is high in stability, can be suitable for the manufacturing and installation of various special-shaped steel structure box girders, well guarantees the overall line type of the steel box girder, and can effectively prevent the deformation of the box body due to the self weight and other factors.
