Description

Technical Field

[0001] This utility model relates to the technical field of variable diameter box-type steel structures, specifically a multi-layer variable diameter box-type steel structure. Background Technology

[0002] Box-type steel structures are mostly used in factory buildings. Box-type steel columns are often manufactured as variable-diameter structures, with a larger diameter at the bottom and a smaller diameter at the top. However, in existing technologies, during installation, the upper and lower support columns of variable-diameter box-type steel structures are usually directly welded to their outer walls. During use, these variable-diameter sections are prone to deformation under pressure, reducing the connection strength between the upper and lower support columns. Furthermore, welding at the connection points can also cause deformation, affecting the overall dimensions. Therefore, a multi-layer variable-diameter box-type steel structure is proposed to improve connection strength. Summary of the Invention

[0003] The purpose of this invention is to propose a multi-layer variable diameter box-type steel structure to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer variable diameter box-type steel structure, comprising a lower support column, a variable diameter support column integrally formed with the lower support column, and an upper support column connected to the variable diameter support column; characterized in that the variable diameter support column is provided with a plug-in protrusion plate connected to the upper support column; the upper support column is provided with a plug-in groove adapted to the plug-in protrusion plate; and a number of reinforcing ribs for improving connection strength are also installed inside the lower support column and at the connection between the upper support column and the variable diameter support column.

[0005] Preferably, the upper support, lower support, and variable diameter support all include symmetrically arranged wing plates and web plates mounted on the wing plates.

[0006] Preferably, the insertion protrusion on the variable diameter support is disposed on the web; the insertion groove of the upper support is disposed between the wing plates.

[0007] Preferably, both the variable diameter support and the upper support are provided with docking platforms on their flanges.

[0008] Preferably, an electroslag welding plate is installed between the wing plate and the reinforcing rib plate.

[0009] Preferably, support strips are installed between the reinforcing ribs to support the reinforcing ribs.

[0010] The beneficial effects of this utility model are: by inserting the plug-in protrusion on the variable diameter support of the lower support into the plug-in groove on the upper support, the lower support and the upper support are pre-connected, thereby improving the convenience of connection between the lower support and the upper support.

[0011] By using reinforcing ribs installed inside the lower support column and at the connection between the upper support column and the variable diameter support column, the connection strength at the connection between the variable diameter support column and the upper support column is ensured, while also ensuring the installation dimensions and preventing deformation during the installation process.
