Fully fabricated concrete beam-concrete column-steel support combination connection node

Abstract

The invention discloses a fully fabricated concrete beam-concretecolumn-steel support combination connection node. The fully fabricated concrete beam-concrete column-steel support combination connection node comprisesfabricated concrete columns, fabricated concretebeams, a hinged connection plate and a square steel support, the fabricated concrete columns comprisevertical embedded parts, vertical longitudinal reinforcements and vertical stirrups, the fabricated concretebeams comprise horizontalembedded parts, horizontallongitudinal reinforcements and horizontalstirrups, two support end plates are arranged at the end portions of the square steel support, and the support end plates are connected with steel support connectors through a shaft pin, the steel support connectorsand the fabricated concrete columns are connected by vertical pair of threaded screws, the steel support connectors and the fabricated concrete beams are connected by horizontal through screws. The combination connection nodecan improve the seismic resistance of a composite node and reduce the damage of components, so that the combination connection node cannot be damaged in an earthquake and has sufficient bearing capacity,the combination connection node has the advantages of good seismic performance, post-earthquake function recovery, high assembly efficiency and simple construction.

Description

technical field [0001] The invention relates to the technical field of prefabricated building structures, in particular to a fully assembled concrete beam-concrete column-steel support composite connection node. Background technique [0002] The fully prefabricated concrete frame structure is mainly composed of precast concrete columns, precast concrete beams, precast floor slabs and dry connection nodes. Since the rotational stiffness of the dry connection joint is smaller than that of the traditional cast-in-place concrete beam-column joint, it has a great impact on the lateral stiffness and seismic performance of the structure, and at the same time, it also greatly affects the use of this structural system. limit. In addition, the current state puts forward higher requirements on the seismic performance and post-earthquake functional recovery ability of the structure. The performance of the fully assembled concrete frame structure needs to be further increased to make th...
