Next, in order to make the back surface side member B of the structural plywood, the same narrow plate material as the surface side member A is made, and the surface side member A and the oblique angle and the oblique direction are the same. The slanted plate of the same size as that of the front side member A with a simple bonding configuration, and the slanted plate of the front side member A and the back side member B, which is completed in the same manner as the plywood size, is slanted on the front side and the back side. It is characterized by joining the front and back diagonal plates so that the angles of It is set to.
As described above, the slanting plate has a crossing posture in which the diagonal angle is opposite to each other, so that when the load from the side is applied, the load can be received on the entire surface of the slanting plate. It is possible to provide a structural plywood for a house formed by cross-joining front and back plate members advantageous to each other.

  Third, the narrow plate material is composed of cedar, cedar, etc., and the thickness of the plate material is about 10 mm to 40 mm, the width is about 60 mm to 120 mm, and the plywood size is 900 mm x 1800 mm Since it is characterized by being configured to 2700 mm, it is possible to make effective use of thinned wood, etc., and to make a structural plywood for housing made by cross-joining front and back plate members using existing lumber equipment at low cost be able to.

  Fourthly, as a parallel plate, the front side is parallel to the long side and the back side is parallel to the short side direction. Thus, the structural plywood for housing can be produced at low cost.

  Fifth, it is characterized by incorporating a thin waterproof sheet and / or a heat insulating material on the adhesive surface between the front side member A and the back side member B, and this is advantageous in terms of strength and waterproof. It is possible to provide a structural plywood for a house that is obtained by cross-joining front and back plate members having excellent properties and heat insulation properties.

  According to the present invention, the front plate and the back plate are made of parallel plates that are crossed vertically and horizontally so that they are crossed with each other in the opposite direction, or a slanted plate in an intersecting posture in which diagonal angles are opposite to each other. It is possible to provide a structural plywood for housing that is formed by cross-joining the front and back plate members, and to receive the load on the entire surface of the plate member constituting the structural plywood for housing even when a load is applied from the side. Therefore, it is strong in strength and can be used at a low cost by making it possible to use thinned wood.

And these structural plywood for housing can be used for ceiling materials, wall materials, flooring materials, etc., and can also be used as wooden doors, sliding doors, joinery materials, table top plates, furniture horizontal plates, etc. is there.
In particular, when used as a table top plate, there is an advantage that a material having a strength higher than that of an ordinary single plate currently on the market can be obtained.
