Cold-bending thin wall steel column base structure

The utility model discloses a cold-bending thin wall steel column base structure, and belongs to the field of a building steel structure. The cold-bending thin wall steel column base structure in the design is composed of a steel column, a transitional connection seat, and an embedded steel sheet connector, wherein the steel column is composed of two back-to-back C-shaped cold-bending thin wall steels; the transitional connection seat is a back-to-back C-shaped steel plate and correspondingly sleeved at the inner bottom part of the steel column; a web plate and a flange plate of the transitional connection seat respectively correspond to the web plate and the flange plate of the steel column and are connected by bolts; and the steel column is welded and fastened together with the embedded steel plate connector through the transitional connection seat. The cold-bending thin wall steel column base structure is simple in structure; and the transitional connection seat is connected by the bolt at the lower end of the steel column and then connected with the embedded bottom plate in a welding manner. Thus, the problem that the cold-bending thin wall steel column cannot be directly welded with the embedded plate is solved; the carrying capacity of the steel column is increased; and furthermore, the cold-bending thin wall steel column base structure is convenient to install, low in construction cost, safe and reliable.
