In the case of LVL as a core material and decorative veneer adhered to the surface, the fiber direction of the LVL veneer is parallel to the longitudinal direction of the tread to increase the bending strength in the longitudinal direction of the tread. Used as
The decorative veneers to be attached to the front and back and side surfaces are also generally attached so that the longitudinal direction and the fiber direction are parallel.

It has excellent stability of about 0.04% and excellent surface smoothness. Furthermore, with the fiberboard obtained by the wet method,
Due to the movement of water at the time of heating and pressing and the amount of the adhesive applied to the wood fiber, the fiberboard having a hard layer (black rock layer) having a significantly higher specific gravity than the other parts in the vicinity of the front and back sides is formed. It is preferable to sand the layer so that it is exposed on the front and back surfaces.

The dimensional change in the direction orthogonal to the direction of the dimensional change in the direction parallel to (the fiber direction of the wood piece) is very 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 adhered to the surface of the architectural plate of the present invention, the decorative veneer does not crack.

The irregularities appear even on the decorative surface, but by adhering the fiberboard, the fiberboard absorbs the irregularities and the surface has excellent smoothness, so that an excellent finish can be obtained. Furthermore, the use of a fiberboard with a hard layer on the front and back makes it a building board with a high surface hardness, a special product that is hard to dent even when a load is locally applied by a drop test of iron balls on the surface, high heels or casters etc. Will have.

Examples thereof include those in which a decorative material such as a resin-impregnated decorative paper or a synthetic resin decorative sheet is adhered with an adhesive. In addition, these decorative materials can be stuck on the back surface and the side surface as well as on the front surface, if necessary. For example, when used as a step board for stairs, as shown in FIG. 2, the decorative veneers 4a, 4

In particular, when a decorative veneer that is likely to expand and contract due to the moisture content is attached to the front side, a veneer of the same thickness (hereinafter referred to as a backing veneer) is also attached to the back side to obtain the front and back surfaces. In the same manner, the veneer expands and contracts in the same manner. For example, when the decorative veneer contracts on the front side, the backing veneer also contracts on the back side, and since the contraction force is equal, the laminated plate warps. Can be prevented.

使用が可能なものである。According to the architectural board of the present invention, the orientation of wood pieces in the obverse and reverse layers of the oriented particle board is the same as that of the rectangular laminated board in which the fiberboard is adhered to the obverse and reverse of the oriented particle board having a plurality of layers. Since it is made parallel to the longitudinal direction of the laminated board, the flexural strength in the longitudinal direction is particularly excellent, and it can be sufficiently used even in a situation where a very strong flexural strength is required, such as a stair tread.

In this case, it is possible to prevent the decorative veneer on the surface from being dried. In addition, since the fiberboard has a high surface strength and excellent smoothness, an excellent finish of the decorative surface can be obtained, and a decorative surface having characteristics of being hardly dented even when a load is applied locally can be obtained.
