Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to wood board materials used for baseboards, fixtures such as door opening frames, and stair treads.

[Prior art] Conventionally, this type of wood board material has been ordinary plywood, decorative plywood with decorative veneer attached to a plywood base plate, or laminated veneer material with several veneers interposed at right angles in the fiber direction. Ta.

[Problems to be solved by the invention] The wooden boards according to the above-mentioned conventional technology can be used as baseboards,
When painted and used as a construction material for edges, stair treads, etc., the paint on the end surface may be absorbed unevenly, and the difference in tone between the veneers becomes noticeable, which may impair the aesthetic appearance. Ta. Therefore, LVL
When parallel plywood is painted and used as a construction material, it looks good because the uneven paint absorption of the veneer is eliminated on the end surface of the wood, but it is susceptible to swelling and shrinkage due to moisture absorption and desorption, which is a characteristic of wood. This had the disadvantage of causing warping and misalignment of the fixtures.

[Means for Solving the Problems] In order to solve the above problems, the following methods can be cited. In other words, in a laminated veneer material that includes one or more layers of veneer with orthogonal fiber directions, the veneer layer with orthogonal fiber directions has a width equal to the thickness of the veneer layer on the end surface in the longitudinal direction. The veneer is interposed so as to form a recess, and the recess is filled with another veneer, and each veneer on the end surface is flush and has the same fiber direction to constitute a wood board material. . In addition, the following method can be mentioned as a manufacturing method of this wood board material.

The first method is almost the same as the method for manufacturing veneer laminates, in which veneers are laminated with one or more veneers interposed with the fiber directions perpendicular to each other, but only the veneers with the fiber directions perpendicular to each other are the same. The veneers are laminated by slightly shifting the veneer in the horizontal direction, interposing a veneer whose fiber direction is parallel to the amount of the shift, and cutting the board material made by hot pressure molding into the desired configuration. , to obtain the desired wood board material.

The second method is to cut out the veneers whose fiber directions are perpendicular to each other by a certain depth from the longitudinal end of the veneer laminated material, which has one or more layers of veneers whose fiber directions are perpendicular to each other. Then, a recess is formed and another veneer is inserted so that the fiber directions are parallel to each other so as to fill the recess, thereby obtaining the desired wood board material.

[Effects of the invention] Since the wood board has the above-mentioned structure, it goes without saying that the warping and deformation of the wood board can be suppressed, and the end surface of the wood board has a good appearance and is finished smoothly, giving it a sense of beauty. effective.

[Example] Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the present invention used for construction materials such as baseboards and surrounding edges. As is clear from the figure, the structure of this fixture A is such that two veneers 1a with orthogonal fiber directions are interposed, and these veneer layers with orthogonal fiber directions are arranged on the longitudinal end surface 2a.
A recess 3a having a width equal to the thickness of the veneer layer is formed between the two layers. 4a is the end surface 2a
This is another veneer that fills the recess 3a so that the fiber directions of the veneer are aligned. 5a is a groove, which forms a type of accent pattern when the construction material A is used for a baseboard, a surrounding edge, etc. Note that a decorative veneer (not shown) may be attached to the surface of this feature A.

[Other Embodiments] FIG. 2 shows another embodiment of the present invention, which is used for stair treads. As is clear from the figure, the configuration of this tread B is that three veneers 1b with orthogonal fiber directions are interposed, and these veneer layers with orthogonal fiber directions are arranged on the end surface 2 in the longitudinal direction.
b to form a recess 3b having a width equal to the thickness of the veneer layer. 4b has the same structure as another veneer 4a in the above embodiment.

Note that this laminated material is processed as a stair tread, so it has a notch 5b as shown in the figure.
