Description

TECHNICAL FIELD

[0001] The utility model relates to steel structure column technical field, specifically a splicing type steel structure column with buffer structure. BACKGROUND

[0002] Steel structure column refers to the load-bearing support element in the steel structure system, which bears the vertical load and transmits it to the foundation. It is usually made of steel pipe, H-shaped steel and other materials, which have good plastic deformation capacity and strength, helping to improve the seismic and wind resistance of steel structure column. The splicing type steel structure column is usually composed of multiple units, which can facilitate transportation and significantly reduce transportation costs.

[0003] The utility model discloses a splicing type steel structure column, which is disclosed in the utility model with publication number CN211714193U. In the utility model, a plurality of equidistantly distributed limiting screw holes are formed in the side walls on both sides of the support steel frame in the length direction of the support steel frame, and a load-bearing lap joint block is arranged on the inner side of the support steel frame. The position of the load-bearing lap joint block can be fixed at any time according to the required installation height. When installing the plug-in steel frame, the operator does not need to lift the plug-in steel frame for a long time.

[0004] In the above technical solution, the steel structure column is composed of a support steel frame and a plug-in steel frame. Although it can facilitate transportation, the plug-in steel frame is inserted into the support steel frame, so it cannot be spliced multiple times. The height of the steel column cannot be freely adjusted. In addition, since there is no buffer and shock absorption measure at the bottom of the column, it is difficult to weaken the transmission of vibration in the steel column, which is not conducive to reducing structural fatigue and damage caused by vibration. Therefore, in view of the above problems, a splicing type steel structure column with buffer structure is proposed. UTILITY MODEL CONTENTS
