Fabricated concrete beam-column joint and construction method thereof

Abstract

The invention provides a fabricated concrete beam-column joint and a construction method thereof, belongs to the field of building structure and solves the problem that existing concrete beam-column joints are low in construction efficiency. The fabricated concrete beam-column joint comprises a pipe column and a structure beam and further comprises four connection members, each connection member comprises a sleeve plate, a column connection plate, a beam connection plate and a connection plate, each sleeve plate is fixed on the pipe column through a fastening member, each adjacent two connection members are fixed through a fastening member and form a beam connection end, column rebar holes are formed in each column connection plate, binding rebar holes and binding rebar grooves are formedin each beam connection plate, beam rebar holes are formed between two connection plates, a rebar cage is arranged in the structure beam and comprises beam rebars penetrating into the beam rebar holes, inner stirrups and outer stirrups, the outer stirrups coat the beam connection ends and are clamped in the binding rebar grooves, the beam rebars are bound on the outer stirrups, the inner stirrupspenetrate the binding rebar holes and tightly hold the two connection plates, and the beam rebars are bound on the inner stirrups; the rebar cage further comprises column rebars penetrating the columnrebar holes. The fabricated concrete beam-column joint is convenient and efficient in construction.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to an assembled concrete beam-column joint and a construction method thereof. Background technique [0002] At present, as a new type of construction technology, prefabricated buildings are gradually recognized by people because of their convenient production, safety and reliability, and cost-saving features. Traditionally, the annular plate is welded on the outside of the sleeve, and the sleeve is placed on the pipe column. After that, support the end of the reinforcement cage in the structural beam on the annular plate and fix it before pouring; since the sleeve is an integral structure, construction cannot be carried out in the middle of the pipe string, and the top mechanism of the pipe string can only be disassembled, and then the The sleeve is inserted from the top of the pipe string, resulting in low construction efficiency and limited construction scenarios. The cu...

[0002] At present, as a new type of construction technology, prefabricated buildings are gradually recognized by people because of their convenient production, safety and reliability, and cost-saving features. Traditionally, the annular plate is welded on the outside of the sleeve, and the sleeve is placed on the pipe column. After that, support the end of the reinforcement cage in the structural beam on the annular plate and fix it before pouring; since the sleeve is an integral structure, construction cannot be carried out in the middle of the pipe string, and the top mechanism of the pipe string can only be disassembled, and then the The sleeve is inserted from the top of the pipe string, resulting in low construction efficiency and limited construction scenarios. The current method is mainly welding, the construction procedure is complicated, and it is not easy to achieve rigid connection. Therefore, it is necessary to improve
