Abstract

The utility model relates to a half-punched core joint between a concrete-filled double skin steel tube column and a steel frame girder, and belongs to a structural form of a structural joint. The joint connects the steel frame girder to an inner steel tube and an outer steel tube respectively through a weld joint and transfers force and bending moment. Double skin steel tube concretes can adopt the cross section types as follows: a round is enclosed by the round, the round is enclosed by a square, the square is enclosed by the round, the square is enclosed by the square, a rectangle is enclosed by the rectangle, the rectangle is enclosed by the square, and the rectangle is enclosed by the round; steels thereof can adopt general strength steels or high strength steels; the concretes can be common concretes or high strength concretes and self-compaction concretes; and a thin-wall steel tube can be adopted. By adopting the half-punched core joint, the unfavorable conditions that only the outer steel tube bears the force and the bending moment can be avoided, an enforced loop plane does not need to be arranged between the outer steel tube and the steel frame girder, the steels are saved, and useful use space is increased; holes are opened on an upper flange and a lower flange of the steel frame girder between the inner steel tube and the outer steel tube, thereby being easy to ensure the pouring quality of the concretes; and the mechanized production is facilitated, and the field operation workload is reduced.
