Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel material used as furniture for furniture, fittings and houses, and more particularly to a panel material suitable for a wall material such as a staircase wall and a staircase wall formed by the panel material. .

[0002]

2. Description of the Related Art Due to the depletion of logs, it has become difficult to assemble furniture and fittings with Muku wood.
In recent years, panel materials such as so-called flash panels, in which a surface material is attached to a core material formed in a frame shape, are frequently used as materials for furniture and fittings.

[0003] However, since the above-mentioned flash panel has a hollow inside in structure, the sound at the time of contact does not feel heavy, and furniture and fittings assembled using the flash panel lack luxury. There were drawbacks.

Therefore, as an alternative to the above-mentioned flash panel, a core plate is formed by arranging a plurality of fine materials (muk materials) formed by sawn wood and floor material waste in parallel along the longitudinal direction. Panel materials such as lumbar core plywood (lamin board, block board, and batten board) in which various wooden boards are adhered to the surface of the core board are used.

[0005]

However, the above-mentioned panel material such as lumbar core plywood or the like usually constitutes the core plate because the fine materials constituting the core plate are bonded to each other by an adhesive. There is a problem that the entire panel material is likely to be warped due to the expansion and contraction of each fine material.

[0006] Further, since it takes time to bond the thin materials, there is a problem that the manufacturing cost of the panel material itself is increased and the weight of the panel material is increased by the amount of the adhesive used.

Further, when a thick stepped wall or the like is formed only by the panel material such as the lumbar core plywood described above, the strength of the stepped wall is increased, but the weight is extremely increased, and the handleability and workability of the panel material are increased. Is worse.

It is an object of the present invention to provide a panel material capable of minimizing warpage, improving productivity and workability, and reducing product cost, and a staircase wall formed by the panel material. is there.

[0009]

In order to solve the above-mentioned problems, the present invention is directed to a panel material in which a plate material is fixed to a side surface of a frame material, wherein the plate materials are arranged side by side in a non-adhered state. And a wood thin plate laminated on each of the front and back surfaces of the core plate with an adhesive, and the wood thin plates laminated on the front and back surfaces of the core plate, respectively. However, the present invention provides a panel material having a fiber direction different from the fiber direction of the core plate.

[0010] As the plate material, a plurality of core plates formed by arranging a plurality of thin materials in a non-adhered state are laminated via an intermediate material bonded to the core plate with an adhesive, and What laminated | stacked the thin wood board on the outer surface of the said core board of an outer layer via the adhesive agent can also be used.

The plate member may be fixed to only one side surface of the frame member, or may be fixed to both side surfaces of the frame member. When the plate members are fixed to both side surfaces of the frame member, it is preferable that two plate members are fixed to the frame member so that the fiber directions of the cores constituting the plate member are different from each other.

It is desirable to use a frame member having a vertical bar because the strength of the entire panel member is improved.

The above-mentioned panel material can be used as a building material for furniture, fittings, and houses, and is particularly suitable as a material for forming a staircase wall. As a result, the manufacturing cost can be reduced and the workability can be improved.

[0014]

Embodiments will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the panel member 1 includes a rectangular frame member 10 formed by combining square members, and a plate member 20 fixed to one side surface of the frame member 10 via an adhesive. It is composed of As a method of fixing the frame member 10 and the plate member 20, nailing, screwing, or the like can be employed in addition to the above-described bonding using an adhesive.

As shown in FIG. 1, the plate member 20 includes a core plate 21 and a thin wood plate 23 laminated on the front and back surfaces of the core plate 21 with an adhesive (not shown). The thin wood board 23 is attached to the core board 2 so that the fiber direction of the core board 21 and the fiber direction of the wood thin board 23 are perpendicular to each other.
1 are laminated on the front and back surfaces.

The core plate 21 has a plurality of fine members 22 arranged side by side in a non-adhered state.
A flat plate structure is maintained by tying the whole of the plurality of narrow members 22 arranged in parallel with a thread (not shown).

The fine material 22 constituting the core plate 21 includes a suma (specific gravity: 0.26 to 0.41), a balsa (specific gravity: 0.10 to 0.17), and a falcata (specific gravity:
0.3-0.4) southern lumber, and cedar (specific gravity:
Low specific gravity wood such as 0.38) is used.

As described above, in the panel member 1 configured as described above, since the plurality of fine members 22 forming the core plate 21 are not bonded to each other, each of the fine members 22 expands individually. Even in the case of contraction, the stress due to the expansion and contraction is dispersed, and the warpage of the plate member 20 and thus the entire panel member 1 can be suppressed to a small value.

Further, since the step of applying an adhesive to the fine member 22 is not required in manufacturing the core plate 21, the manufacturing of the core plate 21 can be easily performed, and the thin members are bonded to each other by the adhesive. Lightweight panel material 1 compared to the case
Can be manufactured at low cost.

Further, since the fiber direction of the two thin wooden boards 23 laminated on the core board 21 is orthogonal to the fiber direction of the core board 21, the strength in the direction perpendicular to the fiber direction of the core board 21 is increased. .

In the above-described panel member 1, the plate member 20 is fixed to one side surface of the frame member 10, but the present invention is not limited to this. For example, as shown in FIGS. The plate members 20 can be fixed to both side surfaces of the plate 10, respectively. As described above, the plate members 2 are provided on both sides of the frame member 10 respectively.
In the case where 0 is fixed, as shown in FIG. 5, it is desirable to fix both plate members 20 to the frame member 10 such that the fiber directions of the core plates 21 constituting the respective plate members 20 are different from each other. If the plate member 20 is fixed to the frame member 10 in this manner, the strength of the formed panel member in the vertical direction and the strength in the horizontal direction are equalized, and the warpage of the entire panel member is reduced.

The frame member 10 constituting the above-described panel member 1 has a square member attached so as to surround the periphery of the panel member 1. However, as shown in FIG. 6, a vertical bar 11 may be provided. . In that case, as shown in FIG.
When the frame member 10 and the plate member 20 are fixed so that the fiber direction of the core plate 21 is oriented in the longitudinal direction, that is, the longitudinal direction of the core member 21, the vertical warpage of the panel member can be reduced and the entire panel member can be reduced. Can be improved in strength. Further, the frame member 10 may be provided with a horizontal bar together with the vertical bar 11 described above.

Also, in each of the above-described embodiments, each of the core members 21 formed by a large number of thin members 22 arranged side by side in a non-adhered state uses a plate member 20 in which thin wood plates 23 are laminated on both front and back surfaces. Although the panel material is formed, when it is desired to increase the thickness of the plate material, for example, as shown in FIG. 7, two cores formed by arranging a plurality of thin materials 22 in a non-adhered state are arranged. The boards 21 are laminated via an intermediate member 24 made of a wood board adhered to the core board 21 with an adhesive,
A wood thin plate 23 is laminated on the outer surface of each core 21 via an adhesive, or three or more cores are laminated via a plurality of intermediate members, and an adhesive is formed on the outer surface of the outermost core by an adhesive. It is also possible to form a board by laminating thin wood boards. By adopting a configuration in which the thickness of the plate material is increased in this manner, a waste material whose size is restricted can be effectively used as a material for forming the thin material 22.

In addition, as the intermediate member 24, paper or sheet can be used in addition to a wooden plate such as a thin wood plate, MDF, and hard board. In particular, when paper is used, a rigid resin is used. If special paper such as impregnated paper is used,
This is more preferable because the strength of Oa increases.

Further, the intermediate member 24 is constituted by three wood thin plates sequentially laminated with an adhesive, and the three wood thin plates are arranged such that the fiber directions of adjacent wood thin plates are different from each other. By laminating, the strength of the plate material and thus the entire panel material increases, and the strength of the core material in a direction different from the fiber direction increases, as compared with the case where the thickness of the core material is increased by increasing the thickness of the core plate 21. Become. Especially,
In consideration of the strength of the entire board, it is desirable for the intermediate member 24 to have a thin wood plate adjacent to the core board 21 having a fiber direction different from that of the core board 21.

As described above, by sandwiching the intermediate member 24 between the plurality of core plates 21, the irregularities of the core plate 21 can be absorbed by the intermediate member 24, so that the plurality of core plates 21 are directly laminated. As a result, the unevenness that is amplified can be effectively suppressed, and a beautiful plate material surface without unevenness can be obtained.

A thin wooden plate 23 laminated on the core plate 21
Is not necessarily one, and a plurality of sheets may be sequentially laminated. Note that a plurality of thin wood plates 23
When laminated on the core board 21, the fiber directions of the adjacent thin wooden boards 23 are different from each other, and the fiber directions of the thin wooden boards 23 adjacent to the core board 21 are different from the fiber directions of the core board 21. Is desirable in terms of the strength of the plate material.

FIGS. 8 and 9 show a step wall 2 formed using the panel material having the above-described structure. As shown in the figure, the staircase wall 2 is provided with a trapezoidal frame member 30, and plate members 40a, 40b and a tread plate 41a fixed to one side surface (side surface on the step side) of the frame member 30. It is composed of a step side plate 41 and a plate member 40c fixed to the entire other side surface (corridor side surface) of the frame member 30. The plate members 40a, 40b, and 40c have the same structure as the plate member 20 described above. Things are used.

The stairs wall 2 has veneers 51 and 52 adhered to the exposed kerfs (upper end and side end surfaces), and the outer surface of the plate member 40a has a handrail along the slope of the stairs. 53 is attached.

Although the frame member 30 has a simple trapezoidal shape, when the width of the frame is large, it is desirable to provide a vertical bar 11 as shown in FIG. 6 to reinforce the frame member 30. Further, the plate members 40a, 40b and 40c correspond to FIG.
As shown in FIG. 6 or FIG. 6, a single core board may have laminated thin wood on both front and back surfaces, and as shown in FIG. It may be a laminate of thin plates. Further, the directions of the plate members 40a, 40b, and 40c fixed to the frame member 30 (the fiber directions of the core plate) are the same as those in the case of the panel material described above.
What is necessary is just to set suitably considering warpage etc.

The staircase wall 2 configured as described above has the following effects in addition to the effects obtained for the panel material described above. That is, the plate members 40 a and 40 fixed to the frame member 30.
Since b and 40c have a certain thickness, when attaching the handrail 53 or the like to the wall surface, the wood for fixing the handrail fitting or the like is aligned with the fixing position of the handrail fitting or the like so that the frame 3
It is not necessary to provide the handrail 53 at any position on the plate member 40a or the like.

[0032]

As described above, claims 1 to 6 are as described above.
In the panel material and staircase wall described in the above, since a plurality of fine materials constituting the core plate of the plate material are not bonded to each other, expansion and shrinkage of the fine material during use over time are absorbed, and the entire plate material and the entire panel material are absorbed. In addition, warpage of the entire staircase wall can be reduced.

Further, in manufacturing the core plate, the step of bonding the thin material is not required and no adhesive is used, so that a lightweight panel material and a staircase wall can be manufactured at low cost.
