specific Embodiment
[0028] As an optimization scheme of the embodiment of the present invention, please refer to figure 1 with Figure 4 , The I-shaped steel corbel 3 has an upper flange plate, a lower flange plate, and a web for connecting the upper flange plate and the lower flange plate; the T-shaped steel connecting plate The horizontal section is the steel bar connecting plate 4, and the vertical section is the first vertical stiffening plate 6. The first vertical stiffening plate 6 is vertically welded to the steel bar connecting plate 4; the upper flange plate and the lower The flange plates are all parallel to the reinforcing steel connecting plate 4, and the web plate and the first vertical stiffening plate 6 are flat. In this embodiment, the upper flange plate and the lower flange plate are arranged in parallel, and the reinforcing steel connecting plate 4 is also parallel to them to facilitate the connection of the longitudinal force-bearing ribs 8. Moreover, in this embodiment, the fir...

The invention relates to the technical field of buildings, and provides a connecting joint of a reinforced concrete beam and a concrete filled steel tubular column, comprising the reinforced concretebeam, the concrete filled steel tubular column, an I-shaped steel bracket and two T-shaped steel connecting plates arranged on the upper surface and the lower surface of the I-shaped steel bracket respectively, the reinforced concrete beam comprises longitudinal stress ribs, the longitudinal stress ribs are arranged at positions of the two T-shaped steel connecting plates, and at least one row oflongitudinal stress ribs are arranged at each position; and one side of the I-shaped steel bracket is mounted on the concrete filled steel tubular column. According to the connecting joint of the reinforced concrete beam and the concrete filled steel tubular column, the I-shaped steel bracket and the T-shaped steel connecting plates are used for connection, not only are the problems of staggered collection of beam longitudinal bars, ring beam stirrups, annular stiffening plates and the like at joints, difficult steel bar binding, incompact concrete pouring and the like effectively solved, butalso holes are prevented from being formed in the concrete filled steel tubular column, and the problem of connection of a second row of steel bars when two rows of steel bars exist at the joints is perfectly solved.
Description
Technical field [0001] The invention relates to the technical field of construction, in particular to a connection node between a reinforced concrete beam and a steel tube concrete column. Background technique [0002] The current mainstream connection methods for concrete-filled steel tube columns and reinforced concrete beams are as follows: shear force transmission uses ring-shaped corbels or load-bearing pins; bending moment transmission uses ring beams or reinforced concrete-filled steel tube columns. [0003] When the ring beam-ring corbel beam-column connection method is used, the section height of the ring beam is usually higher than the beam section, the section width of the ring beam is not less than the beam section width, and there are requirements for side columns, corner columns or architectural beauty The building has a certain influence, and the steel bars here are intricate, and the quality of steel bar binding and concrete pouring cannot be guaranteed. [0004] Whe...
