Abstract

PROBLEM TO BE SOLVED: To suppress the warping of a panel itself and at the same time, increase the bending strength of the panel. SOLUTION: This panel member is constructed of a middle member 3, an edge member 4 and wood boards 5 laminated on both front and back faces of the middle member 3 and the edge member 4 with an adhesive. The middle member 3 is of a solid wood, and plural strip members 2 whose fiber pattern direction is longitudinal are structurally juxtaposed in such a manner that their respective longitudinal directions are alongside of each other under such a state that the strip members 2 are not bonded and mutually free. In addition, the edge member 4 whose fiber pattern direction is longitudinal is of a solid wood and is set on the lateral end face 3a transverse to the fiber pattern direction of the middle member 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel material for furniture and fittings, and also for building materials for houses.

[0002]

In recent years, it has become difficult to assemble furniture and fittings with Muku material due to depletion of raw wood, and so-called flash panels, in which a surface material is fixed to a frame-shaped core material, are usually used. Make up furniture and fittings.

However, since the flash panel has a space inside, the flash panel is not heavy and has a poor texture.

Therefore, as an alternative to the flash panel, a core plate is formed by arranging a plurality of fine materials (muk material) in parallel with each other in the longitudinal direction, and a wooden board is adhered to the front and back surfaces of the core plate. Panels such as lumber-core-plywood are used.

However, in the above-mentioned panels such as lumbar core-plywood or the like, since the thin materials constituting the core are usually adhered to each other by an adhesive, the expansion and contraction of each of the thin materials constituting the core are made. The problem is that the entire panel is likely to be warped, and the expansion and contraction of the thin material causes unevenness at the joints between the thin materials, which in turn causes lines on the surface of the wooden board due to the unevenness. There was a problem that the design was poor.

[0006]

According to the present invention, there is provided an intermediate plate in which a plurality of fine members made of a chrysanthemum and having a longitudinal direction in a fiber direction are arranged side by side so that the longitudinal directions are free from each other. And a thin material of Muku material provided on at least one end face in a direction orthogonal to the fiber direction of the middle plate and having the fiber direction as a longitudinal direction, and a thin material of Muku material provided on the middle plate and the side end face. It consists of a wooden board bonded and laminated on the front and back surfaces of the material.

[0007] With this configuration, since the plurality of fine members constituting the middle plate are not bonded to each other in a free state, the internal stress of each fine member is dispersed, and the warpage of the entire panel is suppressed to a small value. be able to.

In addition, since at least one end face in the direction perpendicular to the fiber direction of the middle plate is provided with a thin material of the Muku material whose longitudinal direction is the fiber direction, panel bending in the direction perpendicular to the longitudinal direction of the middle plate is provided. The strength of the panel can be improved, and the panel can be finished beautifully.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
As shown in FIGS. 1 and 2, this panel material 1 is a middle plate 3 in which fine materials 2 made of a chalk material and having a fiber direction as a longitudinal direction are free from each other and arranged along the longitudinal direction. When,
A thin material 4 of a Muku material provided on one side end surface 3a in a direction orthogonal to the fiber direction of the middle plate 3 and having the fiber direction as a longitudinal direction, and a thin material provided on the middle plate 3 and the side end surface 3a 4, a wooden board 5 laminated on the front and back surfaces via an adhesive (not shown)
It is composed of

The intermediate plate 3 has a plurality of fine members 2 arranged side by side in a non-adhered state. In manufacturing the plurality of fine members 2, the whole of the plurality of fine members 2 is bound by a thread with an adhesive (not shown). Thus, the flat plate structure is maintained.

The fine material 2 has a suma (specific gravity of 0.26 to
0.41), balsa (specific gravity 0.10-0.17), Falkata (specific gravity 0.3-0.4), southern lumber, and low specific gravity materials such as cedar (specific gravity 0.38) are used. However, it is not particularly limited to these materials.

As the fine material 4 of the Muku material provided on the side end surface, a material having a strong bending strength and a beautiful surface such as beech or mizunara is used, but is not particularly limited to these materials.

As described above, when a low specific gravity material is used for the thin material 2 and a material having a high bending strength is used for the fine material 4 provided on the side end surface, a panel material having a small warpage and a small bending strength is used. Obtainable. Moreover, the fine material 4 may be provided on both end surfaces in the direction orthogonal to the fiber direction of the middle plate 3 as a matter of course. This further improves the panel strength.

The fine members 2 constituting the middle plate 3 may be arranged side by side in the same direction as the longitudinal direction and in the direction orthogonal thereto with the same fiber direction.

The wood board 5 bonded and laminated on the front and back surfaces of the middle board 3 and the thin wood 4 is made of a South Sea wood and has a thickness of
The thin wood plate 5a of mm is bonded and laminated so that the fiber direction of the thin wood plate 5a is orthogonal to the fiber direction of the thin material 2 constituting the middle plate 3.

When the fiber direction of the thin material 2 constituting the middle plate 3 is perpendicular to the fiber direction of the thin wood plate 5a as described above, the panel bending strength in the direction perpendicular to the longitudinal direction of the middle plate 3 is further improved. be able to.

In addition to the wood thin plate 5a, the wood board 5 may be a plywood or a veneer laminated wood thin board, a medium fiber board, an OS
B or a hard board may be used.

Further, a decorative layer may be appropriately formed on the upper surface of the wooden board 5. For example, a veneer, a decorative sheet, or a pattern printing layer may be used.

[0019]

According to the first aspect of the present invention, since the plurality of narrow members constituting the middle plate are not bonded to each other in a free state, the warpage of the entire panel can be suppressed to a small value.

Further, since at least one end face in the direction perpendicular to the fiber direction of the middle plate is provided with a thin material of the Muku material having the fiber direction as the longitudinal direction, panel bending in the direction perpendicular to the longitudinal direction of the middle plate is provided. Strength can be improved.
