Problems solved by technology

Due to its large structural size and thick plates, the tetrahedral giant column is difficult to splice and weld, and the production is complicated. Deformation of the column
[0003] In the prior art, the solution to the deformation of heavy steel components is to correct and repair them, resulting in a waste of labor costs and an increase in production costs. Especially for heavy steel components made of Q420-Z25, due to improper welding methods, it is easy to cause welds Serious quality problems such as cracks lead to a large number of repairs

Abstract

The invention discloses a welding method for a tetrahedral giant column of a steel structure, which is to assemble and weld the front, rear, left and right parts constituting the tetrahedral giant column. Spot welding with the corresponding longitudinal and transverse ribs; ② The main boards of the left and right parts are respectively assembled with the main boards of the front and rear parts by spot welding, and the welding angle between the main boards of the front parts and the main boards of the right parts , The assembly welding angle between the main board of the rear part and the main board of the left part is 90°; the welding angle between the main board of the front part and the main board of the left part is <90°; The assembly welding angle between the main boards of the right parts is >90°; ③ spot-weld the corresponding longitudinal and transverse ribs on the main boards of the left and right parts; ④ weld the spot-welded longitudinal and transverse ribs to the main boards of the corresponding parts ⑤ Weld the alignment ribs between the main boards of adjacent parts into one; ⑥ Weld the inner main weld and outer main weld between the main boards of adjacent parts.

Description

technical field [0001] The invention relates to building construction technology, in particular to a method for welding a steel structure tetrahedron giant column. Background technique [0002] The outer frame of a certain construction project (heavy steel structure), the length of the four frame panels is 3250mm x 2050mm x 2353mm x 3038mm, the material is Q420-Z25, the thickness of the plate is 45mm ~ 60mm, and the four frame panels are equipped with connecting components. One-piece grid-like rib wall. Due to its large structural size and thick plates, the tetrahedral giant column is difficult to splice and weld, and the production is complicated. The column is deformed. [0003] In the prior art, the solution to the deformation of heavy steel components is to correct and repair them, resulting in a waste of labor costs and an increase in production costs. Especially for heavy steel components made of Q420-Z25, due to improper welding methods, it is easy to cause welds S...
