Deformation-free T-shaped steel structure of wing plate and welding formation method of deformation-free T-shaped steel structure

Abstract

The invention provides a deformation-free T-shaped steel structure of a wing plate and a welding formation method of the deformation-free T-shaped steel structure. By adoption of the deformation-freeT-shaped steel structure of the wing plate and the welding formation method of the deformation-free T-shaped steel structure, the problems that in the prior art, after welding formation of a T-shapedsteel structure, a subsequent correction procedure needs to be additionally executed, and consequentially, manpower and material costs are increased, and the formation efficiency of the T-shaped steelstructure is reduced are solved. The deformation-free T-shaped steel structure of the wing plate comprises a web and the wing plate, wherein the top end of the web is longitudinally welded to the center of the bottom surface of the wing plate, and two anti-deformation steel plates are separately welded to the two ends of the top surface of the wing plate. The welding deformation method mainly comprises the steps that the two anti-deformation steel plates with the height being five times that of the wing plate are prepared; then the two anti-deformation steel plates are vertically welded to the two ends of the wing plate; and finally, the top end of the web is welded to the longitudinal center of the bottom surface of the wing plate, and a weld line is kept perpendicular to the anti-deformation steel plates during welding. The two sides of the wing plate are prevented from bending towards a weld joint after welding formation of the T-shaped steel structure, so that subsequent correction is not needed, the manpower and material costs can be effectively reduced, and the formation efficiency of the T-shaped steel structure can be effectively improved.

Description

technical field [0001] The invention relates to a non-deformable T-shaped steel structure of a wing plate and a welding forming method thereof. Background technique [0002] Steel structure production often uses two steel plates to be welded in a "T" shape, especially for some large components, if not prevented in advance, due to the large heat after welding and the shrinkage of the weld, it often causes the lateral welds of the flange to be damaged. direction bending, causing member deformation (such as Figure 4 ), increasing the process of subsequent correction and increasing the cost. [0003] Therefore, designing a non-deformable T-shaped steel structure of the wing plate and its welding forming method, after the T-shaped steel structure is welded and formed, the two sides of the wing plate will not bend in the direction of the weld seam, no subsequent correction is required, and the cost of manpower and material resources is saved. Technologists urgently need to solve...
