Friction damping device for enhancing wood structure mortise and tenon joint

The utility model discloses a friction damping device for reinforcing a wood structure mortise and tenon joint. The friction damping device comprises a steel plate with a steel hoop and a hinged support, stiffening ribs, an outer side steel plate with a bolt sliding track and a hinged support, and an omega-shaped inner side steel plate internally welded with bolts, the damping device is constructed through mutual friction between the omega-shaped inner side steel plate with the internally-welded bolts and the outer side steel plate with the bolt sliding track and the hinged support so as to enhance the wood structure mortise and tenon joint, rigidity of the joint can be improved, meanwhile, energy dissipation and shock absorption capacity can be improved, the tenon pulling amount of the mortise and tenon joint is reduced, and the energy consumption of the mortise and tenon joint is reduced. Beam falling can be effectively prevented by increasing the supporting length of the wood beam; the method can be used f
