Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel structure processing and manufacturing, especially a cross steel column assembly welding anti-deformation device. BACKGROUND

[0002] In the manufacturing process of the cross-shaped steel column, the steel plate is first made into an H-shaped beam and two T-shaped beams, and then the three components are assembled and welded. Since the T-shaped beam and the H-shaped beam cannot be effectively fixed, the components will be deformed due to temperature during welding, which will cause problems in the processing quality of the steel components, especially when the cross column section is large and the plate thickness is thick, the deformation is difficult to recover, which has a great impact on the subsequent steel structure installation and engineering quality. The traditional cross column assembly anti-deformation measure is to weld a reinforcing plate on the T-shaped beam and the H-shaped beam, and then cut off the reinforcing plate after assembly is completed. This method has two drawbacks: first, welding the reinforcing plate itself will cause the T-shaped beam and the H-shaped beam to deform longitudinally; second, after the assembly and welding are completed, the reinforcing plate needs to be cut off, and then polishing, repair and painting are needed, which increases the production process, production cost and cycle. Therefore, it is imperative to invent a cross steel column assembly welding anti-deformation device. SUMMARY
