To provide a binding metal for joining a column of a wood structure building with a horizontal member thereof.

In accordance with anisotropy by strength deformation performance of timber, bending moment of the horizontal member 8 can be transferred by a tensile spline tenon 1, and a shearing force can be transferred by a gusset 12. Thus, a clear structural calculation, which is separated into calculations of the bending moment and the shearing force, can be performed as in the case of a rigid-framed structure serving as a steel structure. The use of the tenon 1 for a joint metal for joining the horizontal members 8 or the columns 9 also enables a transfer of a tensile force of the column 9 and a beam, which is constructed by a truss construction method of the wood structure and a conventional construction method.
