Description

Technical Field

[0001] The invention relates to the field of steel structure processing and manufacturing, in particular to a cross steel column assembly welding anti-deformation device. Background Art

[0002] During the manufacturing process of the cross-shaped steel column of the steel structure, the steel plate must first be made into an H-shaped beam and two T-shaped beams, and then the three components are welded together. Since the T-shaped beam and the H-shaped beam cannot be effectively fixed, the components will be deformed due to the influence of temperature during welding, resulting in quality problems in the processing of the steel components. In particular, when the cross-column has a large cross-section and the plate used is thicker, the deformation is difficult to recover, which has a great impact on the subsequent steel structure installation and engineering quality. The traditional anti-deformation measure for cross-column assembly is to weld stiffeners on the T-shaped beam and the H-shaped beam, and then cut off the stiffeners after assembly. This method has two disadvantages. First, the welding of the stiffeners itself will cause the T-shaped beam and the H-shaped beam to deform in the longitudinal direction. Second, after the welding is completed, the stiffeners need to be cut off, and then polished, repaired and painted, which increases the production process and increases the production cost and cycle. Therefore, it is imperative to invent a cross steel column assembly welding anti-deformation device. Summary of the invention

[0003] In view of the above situation, in order to solve the defects of the prior art, the purpose of the present invention is to provide a cross steel column assembly welding anti-deformation device, which can effectively solve the deformation problem of the cross steel column during the assembly welding process.

[0004] The technical solution solved by the present invention is to include a fixing device and a steel structure jig. The fixing device is a circle formed by connecting a detachable arc-shaped top plate, two detachable arc-shaped side plates and a fixed arc-shaped plate. The fixed arc-shaped plate is welded to the steel structure jig through a welded rib plate. A steel structure cross column is placed on the steel structure jig. L-shaped equilateral fixing plates are welded on the inner arcs of the detachable arc-shaped top plate and the detachable arc-shaped side plates. The intersection points of the two sides of the L-shaped equilateral fixing plate and the center intersection point of the steel structure cross column are on the same axis. A movable groove is provided on the L-shaped equilateral fixing plate. A straight-line fixing plate is inserted in the movable groove. Screws are provided at both ends of the straight-line fixing plate and the straight-line fixing plate is fixed to the L-shaped equilateral fixing plate through nuts. The position of the straight-line fixing plate can be adjusted through the movable groove to meet the fixation of cross-shaped steel columns with different cross-sectional sizes.

[0005] The invention has a simple structure and a reasonable design. It is used in conjunction with a traditional steel structure assembly welding jig. External pressure is applied to the T-beam and H-beam to be assembled to completely fix the T-beam and H-beam. Then welding is performed to solve the deformation problem of the components during the welding process, improve the molding quality, and have a good use effect. It is an innovation in the anti-deformation device for cross steel column assembly welding. BRIEF DESCRIPTION OF THE DRAWINGS
