Abstract

The invention discloses a manufacturing process for a steel box girder. The manufacturing process for the steel box girder comprises the following manufacturing steps: step 1, preparation before manufacturing: (1) a general office organizes a technical exchange conference, then a technical department draws a design drawing according to a conference result, and the process of the drawing is judged; and (2) a purchasing department purchases corresponding materials and tools needed for machining the steel box girder according to the drawing and warehouses the materials, and the purchased steel plate materials are cover plates, longitudinal U-shaped ribs, bottom plates, longitudinal U-shaped stiffening ribs, inclined webs, middle webs, transverse partition plates, cross beams, longitudinal beams and the like. According to the manufacturing process for the steel box girder, through the operation steps, all links in the manufacturing flow for the steel box girder can be strictly controlled, a perfect treatment mode is achieved from material selection and raw material treatment, the influence of small errors on the strength of the steel box girder is avoided, close connection of all the links is guaranteed, and a qualified acceptance report is issued, so that the strength of the steel box girder is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel box girders, in particular to a manufacturing process of steel box girders. Background technique [0002] Steel box girder, also known as steel plate box girder, is a common structural form of long-span bridges. It is generally used on bridges with large spans. It is called steel box girder because it looks like a box. In long-span cable-supported bridges, The span of the steel box main girder is hundreds of meters to even thousands of meters, and it is generally divided into several beam sections for manufacture and installation. Its cross-section has wide and flat shape characteristics, and its aspect ratio reaches about 1:10. [0003] In the construction process of some bridges with large spans, it is necessary to consider the steel box girder as the main structure of the bridge, which can ensure the stability and strength of the bridge. At the same time, the steel box girder can be used to assem...
