1. A prefabricated reinforced concrete beam-column connecting structure, comprising an upper prefabricated column, a lower prefabricated column, and a prefabricated beam, wherein the upper prefabricated column comprises an upper column main reinforcement, an upper column stirrup and upper column concrete, the lower prefabricated column comprises a lower column main reinforcement, a lower column stirrup and lower column concrete, and the prefabricated beam comprises a beam upper main reinforcement, a beam lower main reinforcement, a beam stirrup, and a beam concrete,
wherein the prefabricated reinforced concrete beam-column connecting structure further comprises an upper column transfer member, a lower column transfer member and a connecting slot of beam main reinforcement, wherein an upper end portion of the lower column main reinforcement extends beyond a top surface of the lower column concrete, and a part, extending beyond the lower column concrete, of the lower column main reinforcement is provided with a thread, a shape of a horizontal section of the lower column transfer member is adapted to a shape of a horizontal section the lower prefabricated column, and a lower end portion of the lower column transfer member is sleeved on an upper end portion of the lower prefabricated column,
wherein first horizontal load transfer plates are arranged at intervals in a vertical direction inside the lower column transfer member, first perforations are formed at positions, corresponding to the lower column main reinforcement, on surfaces of the first horizontal load transfer plates, an upper end portion of the lower column main reinforcement passes through the first perforations in sequence and is anchored at a top of an uppermost one of the first horizontal load transfer plates by a first nut, and first grouting holes are formed at a middle of the surfaces of the first horizontal load transfer plates,
wherein a lower end portion of the upper column main reinforcement extends beyond a bottom surface of the upper column concrete, and a part, extending beyond the upper column concrete, of the upper column main reinforcement is provided with a thread, wherein a shape of a horizontal section of the upper column transfer member is adapted to a shape of a horizontal section of the upper prefabricated column, and an upper end portion of the upper column transfer member is sleeved on a lower end portion of the upper prefabricated column, wherein second horizontal load transfer plates are arranged at intervals in a vertical direction inside the upper column transfer member, second perforations are formed at positions, corresponding to the upper column main reinforcement, on surfaces of the second horizontal load transfer plates, a lower end portion of the upper column main reinforcement passes through the second perforations in sequence and is anchored at a bottom of a lowermost one of the second horizontal load transfer plates by a second nut, and second grouting holes are formed at a middle of the surfaces of the second horizontal load transfer plates,
wherein the upper column transfer member is arranged on a top of the lower column transfer member and is connected with the lower column transfer member by welding, a grouting pipe is pre-embedded in the upper column concrete, and a lower end portion of the grouting pipe passes through the first grouting holes in sequence and extends into a joint between the upper prefabricated column and the lower prefabricated column, wherein a joint concrete is poured into a cavity enclosed by the lower column transfer member, the upper column transfer member, the lower prefabricated column, and the upper prefabricated column, wherein the connecting slot of beam main reinforcement is connected to one side of the upper column transfer member and the lower column transfer member, the prefabricated beam is arranged on one side of a joint between the upper prefabricated column and the lower prefabricated column and at a position close to the connecting slot of beam main reinforcement, and an end portion of one side, close to the connecting slot of beam main reinforcement, of the beam upper main reinforcement and an end portion of one side, close to the connecting slot of beam main reinforcement, of the beam lower main reinforcement both extend beyond end portion faces of corresponding sides of the beam concrete,
wherein the end portion of one side of the beam upper main reinforcement close to the connecting slot of beam main reinforcement is bent downward and extends into the connecting slot of beam main reinforcement, the end portion of one side of the beam lower main reinforcement close to the connecting slot of beam main reinforcement is bent upward and extend into the connecting slot of beam main reinforcement, shear bolts are provided at intervals on an outer surface of the connecting slot of beam main reinforcement, and a joint post-casted concrete is poured between the prefabricated beam and the lower column transfer member and between the prefabricated beam and the upper column transfer member.
