Anti-sidewise-bending deformation control device of H-shaped steel component and welding method

Abstract

The invention discloses an anti-sidewise-bending deformation control device of an H-shaped steel component. The anti-sidewise-bending deformation control device comprises an assembly jig, an anti-sidewise-bending device, compression devices, a sliding rail and the to-be-welded component; the anti-sidewise-bending device is located in the middle of the assembly jig; the compression devices with thesame number are arranged on the left side and the right side of the anti-sidewise-bending device; and the compression devices are distributed in the direction of the assembly jig. A welding method comprises the steps: (1) the compression devices are adjusted; (2) a lower flange plate and a web are welded; and (3) an upper flange plate and the web are welded. During welding, the web at a welding point is compressed through the anti-sidewise-bending device, thus deformation and bending of the web in the welding process are avoided, two welding heads are symmetrically arranged on the welding positions of the flange plates and the web, the compression devices work to drive the to-be-welded component to move, the two sides of contact points of the web and the flange plates are synchronously welded through the two welding heads, in the process, the to-be-welded component can be semi-automatically welded, the machining efficiency of the H-shaped component can be improved, and the welding quality of the H-shaped component is guaranteed.

Description

technical field [0001] The invention relates to an H-shaped steel member anti-side bending deformation control device and a welding method thereof in the field of construction engineering. Background technique [0002] At present, the development of steel structure buildings is changing with each passing day. Industrial plants and high-rise civil buildings have successively applied steel structure systems, and the most common components in this type of structure are H-shaped components, because H-shaped components have better mechanical properties and the largest The amount of steel used is saved to a minimum, but in the production process, due to the high height of the web, in the process of welding with the flange plate, deformation caused by welding usually occurs, and side bending deformation is the most common A kind of deformation, but this deformation is quite cumbersome and difficult to control in the later correction process. Therefore, it is necessary to develop a...
