Prefabricated concrete main beam and secondary beam connecting structure and construction method thereof
The invention discloses a prefabricated concrete main beam and secondary beam connecting structure and a construction method thereof. The prefabricated concrete main beam and secondary beam connecting structure comprises a prefabricated main beam and a prefabricated secondary beam, wherein a post-cast section is arranged on the prefabricated main beam; load-bearing bars on the bottom of the prefabricated main beam can continuously penetrate in the post-cast section; main beam stirrups are reserved in the post-cast section of the prefabricated main beam; the prefabricated secondary beam extends into the post-cast section of the prefabricated main beam; longitudinal bars on the prefabricated secondary beam are directly anchored on the prefabricated main beam or are anchored on the prefabricated main beam through additional reinforcements; continuous load-bearing bars are paved in a laminating layer on the upper portion of the prefabricated main beam and penetrate in the upper portion of the prefabricated secondary beam; and the post-cast section is formed by a formwork in a pouring manner. Compared with the prior art, the prefabricated concrete main beam and secondary beam connecting structure has the advantages that a prefabricated main beam and prefabricated secondary beam connection mode is modified so as to facilitate hoisting and connection of prefabricated components, the connection performance of the prefabricated main beam and the prefabricated secondary beam is equal to the effect of a cast-in-place structure, joints are connected to one another firmly, horizontal sleeve grouting connection is not required, materials are saved, the manufacturing cost is reduced, and the prefabricated concrete main beam and secondary beam connecting structure is quick and easy to construct.
