Description of the Related Art Conventionally, as a wood-based structural material of a wooden building, structural laminated wood, structural veneer laminate (LVL) and the like have been used. The allowable stress in compression, tension, and bending in the fiber direction of the structural glued lumber and the allowable indentation stress are about 1.1 to about the allowable stress of ordinary structural timber.
Although it was 1.5 times, the allowable stress was naturally limited by the strength of the base material.

Since it is possible to obtain the same strength, it is possible to use a wooden structural member having the optimum strength and dimensions for a building requiring a large span. In addition, even when there are restrictions on the floor height and the like, the beams can be suppressed as compared with the truss structure and the beam structure, and the space of the building can be used effectively. Further, various advantages can be obtained such that the operation can be simplified, the manufacturing time can be greatly reduced, the productivity can be improved, and the cost can be reduced.
