Problems solved by technology

[0010] The existing prefabricated concrete frame system generally adopts the sleeve or grout anchor connection mode. The former has a complicated connection structure and uses non-common building materials; the latter has a large number of on-site welding operations, which virtually increases safety hazards
Due to process acceptance, the final construction period of both is often longer

Abstract

The invention relates to a connection structure of prefabricated concrete beams and columns. The three embedded parts are all trusses; The two ends of the embedded parts protrude from both sides of the prefabricated column, and are equipped with longitudinal steel bars and stirrups; the second embedded part and the third embedded part are pre-embedded in the two prefabricated beams, and the other ends of the two embedded parts Protrude from the prefabricated beam; the two ends of the first embedded part are respectively connected with the protruding ends of the second embedded part and the third embedded part; the invention is simple, reliable, economical and applicable, and can satisfy the overall seismic reliability of the system , and abandoned on-site welding, construction efficiency and safety have been greatly improved.

Description

technical field [0001] The invention relates to a beam-column connection structure, in particular to a prefabricated concrete beam-column connection structure. Background technique [0002] The cast-in-place concrete technology has disadvantages such as low production efficiency, heavy environmental pollution, and large economic waste, which does not conform to the development trend of low-carbon and environmental protection. In addition, in recent years, my country's construction labor costs have increased year by year, and prefabricated concrete construction technology has become a new trend in the field of housing construction. One of the main development directions of technology development. [0003] Compared with traditional buildings, prefabricated buildings have incomparable advantages: [0004] Component factory production and on-site standardized assembly greatly shorten the construction period; [0005] All components have been prefabricated in the factory, and on...
