[0002] A wooden structure is a structure made purely of wood or mainly of wood to bear the load, which is connected and fixed by various metal connectors or mortise and tenon joints.

[0003] In modern wooden structures, engineered wood replaces logs as structural materials, and metal connectors are used more often to connect structural components, replacing the mortise and tenon joints of traditional wooden structures, making the structure more stable. This type of connection increases the rigidity of the nodes, which can cause brittle failure of the wood and reduce the seismic resistance of the nodes.

[0004] Therefore, the technical problems existing in the prior art need to be solved. Utility Model Content

[0007] A welding screw is provided on the square steel plate, one end of which passes through the fixed base plate and extends to the outer wall on the upper side of the fixed base plate; a fixing nut is threadedly installed on the welding screw, and the fixing nut is respectively located on the outer walls on the upper and lower sides of the fixed base plate.

[0008] Preferably, a spring is provided between the connecting circular tube and the central hole.

[0009] Preferably, one end of the welding screw is fixedly connected to the square steel plate.

[0010] The technical effects and advantages of the utility model are as follows: the error caused by the embedded parts can be offset by adjusting the horizontality of the fixed base plate, the fixed base plate can be fixed by installing the fixing nut on the welding screw to keep it in a stable state, and the anchor bolt can be inserted into the wooden column with holes punched and filled with anchor glue, and the energy can be absorbed by the connection between the fixed base plate and the square steel plate, which can effectively prevent the brittle failure of the wood, and is suitable for wooden columns of various cross-sectional forms, greatly improving the earthquake resistance of the building.
