[0002] In recent years, my country's highways, railways and bridges have developed rapidly. A large number of steel structure bridges have been used in their construction. Most of the steel structure bridges adopt the steel box girder structure. The steel box girder is mainly composed of bottom plate units, web unit components, panel unit components and diaphragm unit components. Among them, the diaphragm unit components are the most numerous, and the manufacturing workload of the diaphragm unit components is huge.

[0003] For example, a deformation correction device for a steel box girder partition unit with publication number CN214866262U, the utility model supports the ribs of the deformed partition unit by means of a support seat with an arc-shaped groove, moves the partition unit so that the deformed position is below the pressure block, and then drives the pressure block through the hydraulic press assembly to squeeze the deformed position of the partition unit, so that the deformed position of the partition unit is corrected to be straight. The operation is simple, which greatly improves the manufacturing quality and efficiency of the steel box girder, and saves a lot of manpower and material resources and costs. However, there are still the following shortcomings when it is used: the plate can be supported by placing it on the support seat, but the size of the flange plate will vary depending on the purpose. The support blocks with fixed spacing are not convenient for supporting plates of different specifications, and the actual practicality is poor. Therefore, a steel box girder flange plate correction device is needed to solve the above problems. Utility Model Content
