Abstract

The invention discloses a prefabricated assembled concrete beam-column node structure and a construction method thereof. The structure includes a prefabricated column, a prefabricated beam, a first threaded connector, a nut, a second threaded connector, a first two-way restraint connector and a second two-way restraint connector; the first two-way restraint connector and the second two-way restraint connector Exactly the same; the first two-way constraining connector includes a main body structure and an ear plate. In the present invention, two identical two-way restraint connectors are spliced ​​into a two-way restraint sleeve through threads, which is convenient for structural maintenance and dismantling; the beam-column nodes are connected through the two-way restraint sleeve, and the prefabricated beam and the two-way restraint are realized through the first threaded connector. The connection of the restraining sleeve forms a reliable strong node, which improves the construction efficiency, lateral restraint ability, and structural integrity and stability. The method is simple and easy to implement and has high efficiency.

Description

technical field [0001] The invention relates to the field of prefabricated assembly of construction engineering, in particular to a prefabricated assembled concrete beam-column node structure and a construction method thereof. Background technique [0002] At present, the prefabricated concrete structure has developed rapidly and has been applied in the engineering field to a certain extent. It connects individual components into a whole through some connection methods, but the connection problem at the nodes restricts its further application. From the construction point of view, the connection at the node is divided into dry connection and wet connection. Wet connections require concrete to be poured in situ, which is complex and slow to construct. Dry connection is a main connection method of prefabricated concrete frame structure at present. It has the advantages of environmental protection, high construction efficiency and easy operation, and has been widely used in str...
