Rectangular concrete filled steel tubular column-reinforced concrete transfer beam joint and arrangement method thereof

The invention discloses a rectangular concrete-filled steel tubular column-reinforced concrete transfer beam joint and an arrangement method thereof. The joint comprises a steel supporting plate arranged between a rectangular concrete-filled steel tubular column and a reinforced concrete transfer beam, stiffening ribs below the supporting plate, primary mechanical joints on the supporting plate and column joint bars. The steel supporting plate is welded to the periphery of the outer edge of the top of the rectangular steel pipe column and fixedly connected to the steel pipe through the stiffening ribs, the first-stage mechanical connector is vertically welded to the steel supporting plate, and joint bars in the mechanical connector serve as column longitudinal bars in the height range of the reinforced concrete transfer beam. According to the structural arrangement, the steel pipes do not stretch into the positions, where the steel bars are arranged, in the transfer beam, and it is guaranteed that the beam lo
