Welding Forming Method of Deformation of T-shaped Steel Wing Plate

Abstract

The invention discloses a T-shaped steel welding forming method for preventing deformation of a wing plate. The technical problems that in the prior art, after the T-shaped steel is welded and formed,the wing plate is likely to bend and deform, the later correction amount is large, and a temporary welding support needs to be separately erected and frequently adjusted in the submerged arc weldingprocess are solved. A wing plate deformation preventing tool is adopted to connect two T-shaped steels into an H shape for welding and forming, the T-shaped steels comprise wing plates and web plates,the wing plate deformation preventing tool comprises temporary connecting plates, the two ends of the temporary connecting plates are welded and fixed on the outer side faces of the web plates of thetwo T-shaped steels correspondingly, and all the temporary connecting plates are distributed at equal intervals. Bending deformation of the T-shaped steel wing plate in the welding process can be effectively reduced, the correction amount needed after the T-shaped steel is welded and formed is reduced, meanwhile, no temporary welding support needs to be built in the T-shaped steel forming submerged arc welding process, the frequent adjustment process of the temporary welding support in the welding process is omitted, the welding difficulty is reduced, and the T-shaped steel welding and forming efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a welding forming method for deformation-resistant wing plates of T-shaped steel. Background technique [0002] Due to the structural characteristics of the cross column, the composite column formed with reinforced concrete is often used in high-rise buildings and venue buildings, and the cross column is generally divided into one H-shaped steel part and two T-shaped steel parts for production. However, during the manufacture of this structure, T-shaped steel is easy to bend and deform due to unilateral heating during welding and forming, especially for T-shaped steel with large web thickness (thickness greater than 20mm) and small width, the bending deformation in the longitudinal direction is especially obvious, such as Figure 5 and 6 As shown, the post-correction amount is very large; in the process of submerged arc welding, a temporary welding support needs to be built separately, and the temporary welding support is freq...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to provide a welding forming method for T-shaped steel anti-wing plate deformation, to solve the problem that the prior art T-shaped steel is welded and formed, and the wing plate is easy to bend and deform, which leads to a large amount of correction in the later stage, and the need for a separate welding process in the submerged arc welding process. Technical issues with temporarily welded supports and requiring frequent adjustments to them
