Description

Technical Field

[0001] The present application relates to the technical field of steel structure buildings, and in particular to a non-uniform diameter Y-shaped circular tube column node component and a manufacturing method thereof. Background Art

[0002] At present, in multi-story frames, airports or stadiums that pursue large spatial spans, non-uniform diameter Y-shaped circular tube columns are often used as vertical support components, that is, the lower supporting steel column adopts a large diameter circular tube column, and the upper part is bifurcated into two smaller inclined circular tube steel columns with the same diameter. The load in the Y-shaped node area is large and the force is complex. How to smoothly transfer the force of the two small diameter inclined steel columns on the upper part to the large diameter main circular tube column on the lower part is a difficult problem.

[0003] The traditional method is to use cast steel nodes in the Y-type node area. For example, the invention patent with publication (announcement) number: CN114673301A provides a new type of cast steel Y-type column structure; the invention patent with publication (announcement) number: CN113668773A provides a Y-type cast steel column and its installation process; but cast steel parts have the following disadvantages: (1) They are brittle materials with coarse grains, poor homogeneity, and looser structure than rolled steel plates. In addition, due to the different heat treatment states after processing, there are differences in microstructure and mechanical properties. (2) The welding of cast steel parts and low-alloy structural steel is the welding of two different materials, which often produces excessive welding shrinkage stress and increases the lamellar tearing tendency of cast steel parts in the thickness direction. (3) If cast steel parts are used, the amount of steel used needs to be doubled compared to rolled steel, and its unit price is three times higher than rolled steel, resulting in higher costs. (4) The processing cycle of cast steel parts is long, which affects the progress of the project.

[0004] Some methods use a top plate or a truncated cone to set the lower main pipe, and the two small round pipes on the upper part are directly located on the top plate or the truncated cone. The oblique force on the upper part of this node cannot be smoothly transmitted to the lower main pipe, and it needs to be reinforced by thickening and widening the top plate and stiffening the plate. The amount of steel used is large and the overall appearance is not coordinated. For example: Publication (Announcement) No.: CN110952720A Invention Patent Y-shaped Steel Pipe Column Base and Publication (Announcement) No.: CN212534808U A Y-shaped column steel structure.
