A method for making a cross transformer box-shaped node

Abstract

The invention discloses a method for manufacturing a cross-shaped box-shaped node, including the assembly and splicing of the cross-shaped column and the box-shaped column; step 1, the assembly and splicing of the cross-shaped column; the cross-shaped column is composed of one H-shaped steel and two T-shaped steels; the steps 2. Assembly and splicing of box-shaped columns, including box-shaped column bottom plate and internal assembly, box-shaped column U-shaped structure assembly, correction of deformed parts according to process requirements, and box-shaped column cover plate assembly; step 3, transitional inlay Repair segment group welding. The present invention preferably avoids the problem of stress concentration by first welding the welding seam of the box-shaped column top partition, then welding the connecting weld seam between the cross column and the box-shaped column, and finally welding the butt weld seam between the wing plate of the cross column and the cover plate of the box-shaped column , and the connecting weld between the cross column and the box column adopts slotted external plug welding, which avoids opening welding holes at the end of the cross column or outside the box column and affecting the appearance of the component, and realizes the cross column and box column The welding quality is controllable, and the cross box section welding process is optimized.

Description

Technical field [0001] The present invention belongs to the technical field of steel structure construction, and in particular, the present invention relates to a cross-type node production method, which is suitable for transition joints of concrete and steel structures in high-rise buildings, and a cross-sectional cross-sectional cross-sectional cross-section of the box column. Background technique [0002] With the continuous development of building steel structure, steel structure is gradually widely used in large-scale public buildings and high-rise buildings. The production process is simply difficult, and the structural form is also broken from a single sex to the complexity, which is undoubtedly a higher requirements for the design and processing of steel structures. [0003] Cross-shaped steel columns and box-type cross-section steel columns are more common forms of structural steel structures, which are relatively mature. However, the binding node of the cross column and...

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.
