Manufacturing method of cross-shaped box type joint

Abstract

The invention discloses a manufacturing method of a cross-shaped box type joint. The method includes assembling and splicing of a cross-shaped column and a box type column. Firstly, the cross-shaped column is assembled and spliced, wherein the cross-shaped column comprises H-shaped steel and two pieces of T-shaped steel; secondly, the box type column is assembled and spliced, wherein a bottom plate and interior of the box type column are assembled, a U-shaped structure of the box type column is assembled, a deformed part is corrected to be qualified according to process manufacturing requirements, and a cover plate of the box type column is assembled; and thirdly, a transition inlaying section is welded. According to the method, a top partition plate welding seam of the box type column iswelded, then the cross-shaped column and the box type column are welded to be connected with the welding seam, and finally, wing plates of the cross-shaped column and the cover plate of the box type column are in butt joint with the welding seam, so that the stress concentration problem is well avoided. The connecting welding seam between the cross-shaped column and the box type column adopts opengroove external plug welding, so that the situation that a welding hole is formed in the end of the cross-shaped column or in the outer side of the box type column and accordingly the appearance of acomponent is affected is avoided, the welding quality of the cross-shaped column and the box type column is controllable, and the cross-shaped box type cross section welding process is optimized.

Description

technical field [0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a method for manufacturing cross-shaped box-shaped joints, which is suitable for the combined construction of transition joints between concrete and steel structures and special-shaped cross-sections of cross columns and box-shaped columns in high-rise buildings. Background technique [0002] With the continuous maturity and development of construction steel structure manufacturing technology, steel structures are gradually widely used in large public buildings and high-rise buildings. The production process has changed from simple to difficult, and the structural form has also broken through from singleness to complexity. This undoubtedly puts forward higher requirements for the design and processing of steel structures. [0003] Cross-section steel columns and box-section steel columns are relatively common structural forms in building steel str...

AI Technical Summary

Problems solved by technology

However, the splicing and welding process of the cross column and box column is relatively complicated, the operation space is limited, the amount of weld seam is large, the deformation and dislocation existing during splicing and welding, or the construction process affects the welding quality and appearance of the components. Forming has a huge impact

However, it is impossible to complete the internal welding by directly extending the cross-shaped web into the box.
