On the inside and outside, form and bond one surface with a slope in one direction from one side of the material to the other side, or two surfaces with a slope in two directions from the core of the material to both II + 2 sides. With,
A number of through holes are drilled in the joint part perpendicular to the material axis, and sheath tubes are driven into these through holes to secure the bonding position.
Next, fixing plates are attached to both sides of the joint, tension members are attached by passing through these and the fixing plates with each sheath tube, and tension is applied to these tension members by taking a reaction force to the fixing plates. The pressure necessary for adhesion is applied to the bonding surface, and after a curing period, the tensile material and fixing plate are removed, and the ends of each sheath tube are closed with wood inserts.

This makes joining possible and increases the strength of the joint to almost the same level as the strength of the base material, the laminated wood itself. In addition, the buried wood closes the through hole and prevents the sheath tube from being exposed.
