Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shaped steel column, in particular to a shock isolation shaped steel column structure. BACKGROUND

[0002] The shaped steel column is a main load-bearing component in building structure, which is generally made by hot rolling process, and the strength is higher by optimizing material and controlling heat treatment process.

[0003] The existing patent with the patent number CN110241920B discloses a steel column connecting structure, which comprises a bottom plate, a plug-in sleeve fixedly connected with the bottom plate, and a locking assembly arranged in the plug-in sleeve. The end of the steel column is plugged into the plug-in sleeve. The locking assembly comprises a moving plate, locking pads arranged at both ends of the moving plate and inclined, and a locking bolt for driving the moving plate to approach the bottom plate so that the locking pad abuts against the inner wall of the steel column. A limiting strip is arranged in the plug-in sleeve, and the limiting strip is fixed on the bottom plate. The limiting strip is parallel and arranged in two. When the locking pad abuts against the steel column, the locking bolt is rotated, the threaded transmission drives the transmission sleeve to approach the bottom plate, and the moving plate is driven to approach the bottom plate. At this time, the end of the locking pad close to the bottom plate abuts against the limiting strip, and the two ends of the locking pad are limited to be relatively far away from each other by the limiting strip. When the moving plate moves towards the bottom plate, the end abuts against the inside of the locking pad and slides relative to it. Then, the two ends of the locking pad far away from the bottom plate are relatively opened, and the end abuts against the inside of the steel column after being opened.

[0004] The above steel column connecting structure can be connected, but it is inconvenient to connect the steel column by threaded transmission to drive the transmission sleeve to approach the bottom plate and drive the moving plate to approach the bottom plate. Meanwhile, the shock isolation of the steel column during installation and use still needs to be improved. In view of the above problems, a shock isolation shaped steel column structure is proposed.
