A beam-column node structure and its preparation method and application
ActiveCN109457817BEasy to installquick installationBuilding constructionsClassical mechanicsBolt connection
The present invention provides a node structure of beams and columns, and a preparation method and application thereof. The node structure of beams and columns comprises a pipe column, a beam and a connector, wherein the pipe column and the beam are vertically connected by a connector, wherein the connector comprises a side plate and a sleeve plate, wherein the side plate and the pipe column are connected by a single-sided bolt, wherein the side plate and the sleeve plate are connected by a single-sided bolt, and wherein the sleeve plate and the beam are connected by a high-strength bolt. The node structure of beams and columns of the present invention can be used for the node connection between columns and beams in an assembled structure. The node structure of beams and columns of the present invention fully utilizes the shear resistance of the single-sided bolts through a specific connection method, so that the force of the structure is more reasonable, and the entire connection has zero welding.
