The invention discloses a square steel tube concrete column-steel beam outer ring sleeve plate bolt connection joint. The square steel tube concrete column-steel beam outer ring sleeve plate bolt connection joint comprises a square steel tube, the square steel tube is sleeved with an upper outer ring sleeve plate and a lower outer ring sleeve plate, the upper outer ring sleeve plate comprises an upper short sleeve, an inner surface of the upper short sleeve is connected with the square steel tube, an outer surface of the upper short sleeve is connected with an upper outer ring plate, the lowerouter ring sleeve plate and the upper outer ring sleeve plate are of the same structure, the lower outer ring sleeve plate comprises a lower short sleeve and a lower outer ring plate, and a steel beam is connected between the upper outer ring sleeve plate and the lower outer ring sleeve plate. The distribution of a column wall yield line is expanded, the column wall rigidity of a joint domain isimproved, and the contribution of an outer ring plate to the joint bearing capacity under the action of external load is increased; the defect that the rigidity at the joint is insufficient due to thefact that an inner ring plate is not arranged is overcome; by adopting the method, the field operation amount is small, the steel structure construction efficiency is improved, the material utilization rate is increased, and good economic benefits and social benefits are achieved.
