Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building materials, in particular to a multi-section variable cross section steel column structure. BACKGROUND

[0002] Multi-section variable cross section steel column structure refers to the use of different cross section forms or sizes in different sections (parts) of the same steel column to meet the mechanical requirements and economic requirements of the structure. This design is usually used in large building structures such as high-rise buildings and bridges, with the purpose of reducing material usage and cost while ensuring the load-bearing capacity and stability of the column. Multi-section variable cross section steel columns usually use different cross section shapes and sizes at different heights (or different sections), such as gradually transitioning from a thicker column body to a thinner column body. This change can be achieved by changing the width, thickness or shape of the column (such as circular, square, rectangular, etc.).

[0003] Currently, the commonly used multi-section variable cross section steel column structure usually adopts a plug-in connection method. Although this plug-in connection method makes the connection between steel columns convenient, it requires one end of the steel column to have a plug-in slot and the other end to have a plug-in block. The connection between two steel columns is achieved through the plug-in slot and the plug-in block. However, the plug-in block and the plug-in slot have a small connection support area between the two connected steel columns, which can cause the connection between the two connected steel columns to withstand poor lateral forces, leading to bending and breaking of the connection between the two connected steel columns.

[0004] Therefore, we propose a multi-section variable cross section steel column structure to solve the above problems. INVENTION CONTENTS
