Description

Technical Field

[0001] The invention relates to the technical field of steel column, in particular to a steel column structure capable of seismic isolation. Background Art

[0002] Steel columns are the main load-bearing components in a building structure and are generally made using a hot rolling process. Their strength is increased by selecting the best material and controlling the heat treatment process.

[0003] The existing patent announcement number CN110241920B discloses a steel column connection structure, including a base plate, a plug-in tube fixedly connected to the base plate, and a locking assembly arranged in the plug-in tube. The end of the steel column is plugged into the plug-in tube. The locking assembly includes a moving plate, locking pads respectively arranged at both ends of the moving plate, and the locking pads are inclined and drive the moving plate to approach the base plate so that the locking pads are pressed against the locking bolts of the inner wall of the steel column; a limit strip is arranged in the plug-in tube, the limit strip is fixed to the base plate, and the limit strip is fixed to the base plate. There are two bars and they are arranged in parallel. When the locking pad abuts against the steel column, the locking bolt is rotated, and the transmission sleeve is moved close to the base plate through threaded transmission, thereby driving the movable plate close to the base plate. At this time, one end of the locking pad close to the base plate abuts against the limit bar, and the limit bar limits the two ends of the locking pads to be relatively far apart. When the movable plate moves toward the base plate, the end abuts against the inner side of the locking pad and slides relative to it, and then the ends of the two locking pads away from the base plate are driven to relatively open, and after opening, this end abuts against the inner side of the steel column.

[0004] The above steel column connection structure can be connected, but the threaded transmission is used to make the transmission sleeve close to the bottom plate, and the moving plate is driven close to the bottom plate, which is inconvenient for the connection of the steel columns. At the same time, the seismic isolation of the steel columns during installation and use still needs to be improved. In view of the above problems, a seismic isolation steel column structure is proposed. Summary of the invention
