CHEN WEI / LI ZHIDE / ZHANG CONG / ZHANG CUI / XU LULU

The invention relates to a novel connecting joint of a concrete filled steel tube composite column and a concrete beam, and belongs to the technical field of composite columns, the novel connecting joint comprises a composite column and a reinforced concrete beam, a protective layer is reserved on the composite column, and the thickness of the protective layer is larger than the beam width of the reinforced concrete beam; the composite column comprises a steel pipe, the steel pipe is located in the composite column, and an anchoring assembly used for being anchored to the reinforced concrete beam is fixed to the outer wall of the steel pipe. When the reinforced concrete beam intersects with the composite column, the reinforced concrete beam penetrates through the protective layer or the end of the reinforced concrete beam is anchored in the protective layer, and the effects that the pouring quality of the joint of the composite column and the reinforced concrete beam is guaranteed, and the construction period is guaranteed are achieved.
