Description of the Related Art In general, lumber products used as structural materials for houses, such as pillars, flooring materials, horizontal members, etc., are manufactured by a lumber manufacturer purchasing raw wood from a lumber market and processing it. In recent years, in structural materials for houses, the strength and shape stability sufficient for use as structural materials for houses have been exceeded by the need for excellent designability of solid sawn timber products obtained by cutting logs into predetermined dimensions as before. The needs for are increasing. One of the reasons is that a house maker wants to avoid complaints from customers caused by deformation of structural materials after building a house. Another reason is that it is desired to purchase a high-strength structural material for a house at a low cost in order to reduce the cost of building a house.
