長手方向と繊維方向が平行となるように貼着される。Although these treads have excellent characteristics in terms of mechanical strength such as bending Young's modulus, they are prone to problems such as warpage due to changes in water content. Further, in the case where a decorative veneer is attached to the surface using LVL as a core material, the fiber direction of the LVL veneer is parallel to the longitudinal direction of the tread plate in order to increase the bending strength in the longitudinal direction of the tread plate. Used as
The decorative veneers to be attached to the front and back surfaces and the side surfaces are also generally attached such that the longitudinal direction and the fiber direction are parallel.

難となりつつある。The tread thus obtained has a large expansion and contraction due to water absorption and release of LVL used as a core material, and a cracking phenomenon occurs in the surface layer portion due to the conduit groove and back crack of the surface veneer. The cracking phenomenon causes countless cracks on the veneer on the surface, and there are problems such as deterioration in quality and deterioration in designability. Now that the problem of depletion of wood has become more serious and calls for conservation of nature have become popular, not only can we obtain sawn timber that can be used as a tread, but also LV.
It is becoming difficult to obtain a good-quality single plate used as a material for L or the like.

とがない。By sticking such a fiber board to the front and back surfaces of the oriented particle board, the oriented particle board alone causes the movement of expansion and contraction due to the change in the water content of the small pieces of wood on the front and back surfaces. The dimensional change in the direction orthogonal to the dimensional change in the direction parallel to (the fiber direction of the small piece of wood) is extremely large, but this movement is suppressed and absorbed by the fiber board with excellent dimensional stability. It will be. Therefore, even if a decorative veneer or the like is attached to the surface of the building board of the present invention, the decorative veneer does not crack.

When applying a decorative material such as a sheet,
Although the unevenness appears even on the decorative surface, by applying the fiber board, the fiber board absorbs the unevenness and the surface is excellent in smoothness, so that an excellent finish can be obtained. Furthermore, by using a fiberboard with hard layers on the front and back surfaces, it becomes a construction board with high surface hardness, and a special product that does not dent even if a load is locally applied by a drop test of iron balls on the surface, high heels or casters Will have.

Examples thereof include those in which decorative materials such as resin-impregnated decorative paper and synthetic resin decorative sheets are attached with an adhesive. Further, these decorative materials can be attached not only to the front surface but also to the back surface and the side surface, if necessary. For example, when it is used as a step board for stairs, as shown in FIG. 2, the decorative veneers 4a, 4 are provided on the front surface, the back surface, and the side surface which is the front surface when used as a step board.

Therefore, it is possible to prevent cracks from occurring in the decorative veneer on the surface in order to prevent the cracks from being transmitted to the veneer. Moreover, since the fiber board has high surface strength and excellent smoothness, an excellent finish of the decorative surface can be obtained, and a decorative surface having a characteristic that it is hard to be dented even when a load is locally applied is obtained.
