The invention provides a pre-stressed assembled beam column node beam-end welding stirrup structure. The structure comprises prefabricated concrete columns, prefabricated concrete beams and superimposed beam top longitudinal bars; the superimposed beam top longitudinal bars penetrate through reinforced steel bar couplers pre-embedded in the prefabricated concrete columns, and are then connected with in-column anchoring reinforced steel bars pre-embedded in the prefabricated concrete columns; the prefabricated concrete beams comprise prefabricated concrete beam bodies, common outward extensionclosed stirrups, beam-end outward extension opened stirrups and superimposed beam bottom longitudinal bars; the common outward extension closed stirrups hoop the superimposed beam bottom longitudinalbars and the superimposed beam top longitudinal bars, two opened ends of each beam-end outward extension opened stirrup are in mutual lap joint, the single faces of the beam-end outward extension opened stirrups form closed stirrups, and then the superimposed beam top longitudinal bars and the superimposed beam bottom longitudinal bars are hooped together. By means of the structure, sufficient operating and adjusting space is provided for the connection of the superimposed beam top longitudinal bars and the reinforced steel bar couplers, and the reinforced steel bar connecting quality is wellguaranteed; meanwhile, lateral deflection of the superimposed beam top longitudinal bars is effectively prevented, and the anti-seismic property of the structure is improved.
Description
technical field [0001] The invention belongs to the technical field of beam-column installation of prefabricated concrete structures, and in particular relates to a prefabricated beam-column crimping node reinforcement connection structure. Background technique [0002] Prefabricated concrete frame structure is a construction method with fast construction speed, good economic and environmental benefits. From the perspective of force and construction convenience, the node structure of the prefabricated structure is the key influencing factor. At present, the beam-column joints of the prefabricated frame structure mostly adopt the method of cast-in-place in the joint area. This method needs to deal with the avoidance of beam-column reinforcement in the joint area, the workload of wet work is large, and the construction efficiency is not high. [0003] Another crimping method of beam-column joints can better avoid the above shortcomings. In its structure, the beam-column joint...
