Restraining steel column adapting to micro-deformation of roof structure

The invention discloses a constraining steel column adapting to micro-deformation of a roof structure. The constraining steel column comprises a column foot embedded part, a column foot and a column cap. The column foot embedded part is embedded in the steel column foundation, the bottom of the column foot is fixedly arranged at the top of the column foot embedded part, the column foot can be inserted into the bottom of the steel column in a matched mode, and the column foot is connected with the steel column in a bell and spigot joint mode, so that the steel column is vertically installed on the steel column foundation; the column cap sleeves the top of the steel column, the column cap is in socket connection with the steel column, and the roof structure is mounted on the column cap. The invention relates to the technical field of building construction, and can solve the quality problem that in the prior art, a steel column restrained reinforced concrete roof structure deforms, so that the reinforced concret
