An anchor bolt is first embedded in the concrete foundation, and the anchor bolt and the concrete are separated by a PVC sleeve. The lower anchor plate of the anchor bolt is fixed with upper and lower nuts, and a hydraulic tensioner is used to apply pre-tensioning force to the anchor bolt. Then, the bottom plate is fixed with the anchor bolt embedded in the concrete foundation. In order to improve the rigidity of the column foot bottom plate and avoid the bottom plate being too thick, an anchor bolt support bracket top plate is added under the anchor bolt, the bottom of the steel column is welded to the bottom plate, and a stiffening plate is set at the connection between the bottom of the steel column and the concrete foundation to strengthen the rigidity of the bottom plate and improve the bearing capacity of the column foot.
