The invention discloses an optimized manufacturing technology for a steel structure box girder. The technology comprises the steps that S1, solid modeling is carried out by utilizing AUTOCAD or SOLIDWORKS three-dimensional software, and accurate lofting is carried out on the positions of box opening of all sections and transverse partition plates; S2, a computer simulates pre-assembling, and the transverse partition plate, a top plate, a web plate and a base plate are manufactured according to solid lofting of the computer; and S3, a jig frame is manufactured, and the base plate, the web plate, the transverse partition plate and the top plate are assembled on the basis of the jig frame. According to the optimized manufacturing technology for the steel structure box girder, accurate loftingand pre-assembling simulating are carried out through the computer, so that the accuracy in the subsequent construction process is improved, pre-assembling is simulated, so that the assembling process is practiced in advance, the operation difficulty of the assembling construction is lowered, and the construction progress is ensured.
Description
Technical field [0001] The invention relates to the technical field of steel structure box girder manufacturing, in particular to an optimized manufacturing process for steel structure box girder. Background technique [0002] With the development of my country's steel industry and steel structure technology, the number of steel structure municipal bridges is increasing. Steel structure box girder has light weight, good overall performance, beautiful structure, high degree of industrial production, fast construction speed, and large clearance under the bridge. And other advantages, making the steel box girder structure widely used in the design and construction of municipal bridges. At the same time, the complexity of the construction environment of steel structure box girder, the diversity of functional requirements, and the large span have brought many technical problems different from the construction of railway and highway steel structure box girder to its production, installa...
