Reinforcing structure of reinforced concrete frame column

The utility model discloses a reinforcing structure of a reinforced concrete frame column, and belongs to the technical field of architectural engineering. When the rebar frame column is a middle column, full-length longitudinal hollow square steel tubes in the vertical direction are arranged along the periphery of the frame column, at least one set of horizontal connecting ribs are arranged between the vertical hollow square tubes on the two adjacent sides of the frame column, a cross-shaped wing wall is formed by cast-in-place reinforced concrete, and the cross-shaped wing wall and the frame column are integrated. The hollow square steel tubes are connected with the column through expansion bolts, the hollow square steel tubes and the column are jointly stressed, and therefore the anti-shearing capacity, the anti-bending capacity and the overall anti-side-placement rigidity of the original frame column are improved. Besides, construction materials are easy to obtain, the construction method is simple, the c
