Connecting joint structure of concrete filled steel tube core column and prefabricated reinforced concrete beam

A connecting joint structure of a concrete filled steel tube core column and a prefabricated reinforced concrete beam comprises a structural column, a structural beam and a beam column connecting joint. The structural column is a concrete filled steel tube core column and comprises a core column, a column vertical steel bar, an upper-section column stirrup, a lower-section column stirrup, upper-section column concrete and lower-section column concrete. The structural beams are arranged close to the structural columns; the structural beam comprises a beam precast concrete member, a beam cast-in-place concrete layer, a beam lower layer main reinforcement, a beam upper layer main reinforcement and a beam stirrup; the beam-column connecting joint comprises outer side joint steel bars, inner side joint steel bars, joint stirrups and joint concrete. The outer side node reinforcing steel bar is arranged between the lower section column concrete and the upper section column concrete; the inner side node reinforcing s
