[0002] At present, with the development of fast-building building structures, more and more houses and other buildings use steel structures and steel-concrete mixed structures to improve the construction efficiency of houses and other buildings. In building structures, most columns are welded with steel plates to form a box-type column structure to support beams, floor slabs, etc. Since the columns adopt a box-type structure, during construction, the box-type columns are usually installed in the foundation, and then concrete is poured to make the box-type columns and the foundation form a whole. In this way, although the stability is good, it will affect the construction efficiency of the box-type columns. Alternatively, screws are embedded in the foundation, and then a connecting plate is welded at the bottom of the box-type column. Finally, the bottom plate is connected to the screws embedded in the foundation through locking nuts to form a fixed structure. However, this construction is very troublesome, especially when the box-type column is a full-length column that can span multiple layers, it is impossible to connect and tighten the locking nuts with the screws, which seriously affects the stability and construction efficiency of the box-type column.
