Assembly type concrete beam column joint with damping device

Abstract

The invention provides an assembly type concrete beam column joint with a damping device, and belongs to the field of architectural and civil engineering. By means of butt joint of groove holes reserved in upper and lower columns and prefabricated T-shaped beams, prefabricated reinforced concrete columns and prefabricated reinforced concrete T-shaped beams are reinforced through L-shaped reinforcing steel plates and special-shaped reinforcing steel plates. In-column external extending steel pipes and in-column external extending main ribs penetrate through the prefabricated reinforced concretecolumns to enhance the bending resistance and pressure resistance of a beam column, and damping supporting rods are arranged between the prefabricated reinforced concrete columns and the prefabricated reinforced concrete T-shaped beams. The prefabricated concrete beam column joint is convenient to construct, the manufacturing cost is reduced, the construction speed is high, and the overall structure accords with the principle that the columns are strong, the beams are weak, joints are strong and components are weak. The structure has multiple damping protection lines and has necessary strength and good deformation performance and energy-dissipating capacity, the structure is easy to connect, the overall stability is high, and joint connection portions can be reinforced to adapt to assembly type integrated development.

Description

technical field [0001] The invention belongs to the field of architectural civil engineering, in particular to an assembled concrete beam-column joint with a shock absorbing device. Background technique [0002] In the prefabricated frame structure, the performance of the beam-column joints is related to the overall performance of the building. From the characteristics of the prefabricated building itself, the quality of the prefabricated components is absolutely reliable, and the combination of these components into a building depends on the nodes, so the performance of the nodes is related to the overall performance of the building. From the perspective of the mechanical characteristics of beam-column joints, not only the mechanism of force bearing and force transmission of beam-column joints is complicated, but also the joints are prone to non-ductile failure. Therefore, the beam-column joint is not only the key part of the building to bear the force, but also the weakes...

Problems solved by technology

In the past, some prefabricated concrete frame structures were designed with poor seismic performance due to the flaws in the joint design. In order to regain confidence in the prefabricated frame structure, it is necessary to solve the problem of the joint connection method of prefabricated components. The problem of improving earthquake resistance
