Hoop type steel reinforced concrete beam column dry type joint structure

Abstract

The invention discloses a hoop type steel reinforced concrete beam column dry type node structure which comprises a prefabricated upper column, a prefabricated lower column, prefabricated beams and hoop type node connecting pieces, the prefabricated upper column and the prefabricated lower column are connected in a mortise and tenon joint mode to form a column body, and the outer side of the column body is fixedly connected with the multiple prefabricated beams through the hoop type node connecting pieces. The prefabricated upper column, the prefabricated lower column, the prefabricated beam and the hoop type node connecting piece are assembled, field installation construction is greatly optimized, column-column connection is achieved in space through the mortise and tenon joint structure and the steel bar sleeve technology, and beam-column connection is achieved through the hoop type node connecting piece; the steel bars are connected in a mechanical connection mode, the anti-seismic requirement can be met, shearing force is transmitted through the hoop type node connecting pieces and the screws, the force transmission path is clear, and the structure is reliable.

Description

technical field [0001] The invention relates to a hoop-type steel-concrete beam-column dry-type joint structure. Background technique [0002] According to the different construction methods of beam-column joints, the connection methods of prefabricated joints can be divided into wet connection and dry connection. Wet connection is to complete the fabrication of beams, columns and other components in the factory in advance, and then transport the components to the site for assembly and hoisting. Concrete is poured at the beam-column joints to form the beam-column as a whole. The current wet connection methods mainly include post-casting of the node area, the overall prefabrication of the node and the world structure system. The dry connection has no post-cast tape, and the components are completely prefabricated in the factory, and can be put into use after being assembled and hoisted on site. The commonly used dry connection methods mainly include tenon connection, weldin...

AI Technical Summary

Problems solved by technology

The connection structure of the precast concrete frame structure is relatively complicated, and the integrity of the structure is poor, and its seismic performance needs to be further studied

The steel frame structure can be welded and bolted, the construction speed is fast, and the seismic performance is good, but the corrosion resistance is poor, the cost is high, and the economic benefit is poor
