Assembly type anti-buckling double-channel-steel beam-column joint connecting device capable of restoring functions

The invention relates to an assembly type anti-buckling double-channel-steel beam-column joint connecting device capable of restoring functions, and belongs to the field of structural engineering. Thebeam-column joint connecting device is composed of a square steel tube column with a cantilever beam section, channel steel beam sections and a connecting device body. Welding parts of the joint connecting device are all completed in a factory, the welding seam precision and quality are easier to control, and the construction speed and the construction quality can be improved; then assembly unitson a construction site are assembled and connected with the square steel tube column with the cantilever beam section through H-shaped beams. Joints are beam end reinforcing and flange cover plate connecting weakening integrated joints, a multi-energy-consumption mechanism can be realized, plastic hinges can be transferred to flange cover plates, and according to the anti-buckling idea, after being buckled, the connected
