Energy dissipation and shock absorption type fabricated beam-column joint

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 eart
