Description
Technical Field
The utility model relates to the technical field of civil engineering structures, in particular to a mortise and tenon joint reinforcing structure.
Background
The mortise and tenon structure is built by using timber and bricks as main building materials and using a timber frame structure as a main structural mode, and is formed by main components such as upright posts, cross beams, along purlins and the like, and joints among the components are anastomosed by mortise and tenon to form an elastic frame. The mortise and tenon joint is an extremely exquisite utility model, and the member connection mode ensures that the traditional Chinese wood structure becomes a special flexible structure body which surpasses the prior-generation building bent frame, frame or steel frame, not only can bear larger load, but also allows certain deformation, and certain earthquake energy is counteracted by the deformation under the earthquake load, so that the earthquake response of the structure is reduced. Under the action of earthquake, the mortise and tenon joint can bear complex external force actions such as stretching, extruding, bending, shearing and the like. So that the engagement between the tenon and the mortise becomes more and more loose, and the tenon slowly slides out of the mortise, namely the so-called tenon pulling phenomenon. Once the tenons or tenons are broken, the connection between the beams and the columns is weakened, and the structural integrity and stability are affected.
The reinforcement of mortise and tenon joint performance plays a vital role in the bearing capacity and the earthquake resistance of the traditional wood structure. The performance reinforcement of the mortise and tenon joint is continuously researched at home, for example, the existing research shows that the carbon fiber cloth is stuck at the bottom of the mortise and tenon joint to well reinforce a wood beam with a defect in a tension zone, and the steel plate is used for reinforcing the wood beam to effectively prevent the development of the existing longitudinal cracks and improve the bearing capacity and rigidity of the damaged wood beam. However, the above-mentioned partial reinforcement mode has a certain limitation, and the appearance is affected by using the steel plate support, and the limitation is larger by using the carbon fiber cloth, which can only act on partial wood beam structure.
The prior Chinese patent CN216041729U is a reinforcing structure for a mortise-tenon joint wood frame node, and provides that a mortise-tenon joint between a vertical column and a transverse beam is connected with a connecting assembly, and displacement of the vertical column and the transverse beam is completely limited by utilizing a self-tapping screw and a preset hole site on the connecting assembly. Compared with the traditional wood structure mortise and tenon joint, the utility model improves the pulling resistance of the joint, can effectively avoid the damages of tenoning and pulling tenoning, but completely limits the displacement, also leads the special flexible structure of the mortise and tenon joint to be damaged, can not generate certain deformation, and can not offset certain earthquake energy through the deformation under earthquake load.
Therefore, in order to solve the technical problems, the utility model provides a mortise and tenon joint reinforcing structure.
