Problems solved by technology

The defect of this technical solution is that it is difficult to realize the mechanism of steel plate deformation energy consumption and frictional energy consumption. The metal deformation is dissipated by the steel beam itself if the stiffness of the angle steel is too large. Target

Abstract

A prefabricated column and a prefabricated beam are connected, and a friction energy dissipation assembly is arranged between the prefabricated column and the prefabricated beam; the friction energy dissipation assembly comprises a gear arm and a gear composite part, the gear composite part is installed on at least one of the prefabricated column and the prefabricated beam, the gear composite part is meshed with a rack, and the rack is arranged on the gear arm; a limiting groove is formed in the gear arm, and a limiting bolt pin with a fixed position is arranged in the limiting groove; the metal energy dissipation assembly achieves energy dissipation through beam-column joint deformation and metal energy dissipation sheet extrusion, the composite energy dissipation benefit of combining friction energy dissipation and metal energy dissipation can be achieved, earthquake energy is dissipated, a component is protected against damage, and the composite energy dissipation performance can be recovered after an earthquake. And the self-resetting capability can be realized by applying pre-stress by combining a pre-stress assembly, and the earthquake isolation effect can be achieved through the rubber shock isolation pad.

Description

technical field [0001] The invention belongs to the technical field of assembled joints, and in particular relates to an energy-dissipating and shock-absorbing assembled beam-column joint. Background technique [0002] The existing connection methods of fabricated concrete beam-column joints are divided into wet connection and dry connection. Or welding and other methods to connect the prefabricated components into a whole. Among them, the dry connection can also be made of tongue and groove connection, that is, the notched beam is directly spliced ​​with the column with the corbel. In order to strengthen the bearing capacity of the connection part, it is generally strengthened by welding and forming of pre-embedded steel plates and built-in steel. However, under the action of horizontal force, the lateral resistance of this node is poor, and the connection part may fail under the action of an earthquake, resulting in huge losses and directly endangering the overall safety ...
