Hereinafter, the present invention will be described in detail based on the illustrated embodiments.
In the panel material according to the present invention, as shown in FIG. 1, a first board material 1 made of plywood, a core material 3 and a second board material 2 made of veneer are sequentially superposed.

  The surfaces 1a and 2a of the first plate 1 and the second plate 2 on the outer surface side of the panel are waterproofed (waterproofed). Specifically, a membrane-like (sheet-like) waterproof layer formed of a resin such as vinyl is laminated. The waterproof treatment prevents water from entering the inside of the panel material and prevents warpage due to changes in temperature and humidity.

As shown in FIGS. 2 and 3, the core material 3 has a large number of strip-shaped paper materials 30 and 30.
The strip-shaped paper material 30 is subjected to waterproof processing (water resistance processing). In other words, it has water repellency (non-water absorbency). The waterproofing process prevents warpage (deformation) or reduction in strength due to temperature or humidity change.

The strip-shaped paper material 30 is disposed on the first plate 1 and the second plate 2 in an orthogonal plane. In other words, in the panel material thickness direction T, the paper material strip width direction of the strip-shaped paper material 30 is made to coincide.
A large number of strip-shaped paper materials 30, 30 are juxtaposed in the panel material longitudinal direction (longitudinal direction) N. Although not shown, it is also free to arrange many paper-like strips 30, 30 in parallel in the panel material width direction (lateral direction) W or in parallel in the diagonal direction of the panel material.
Moreover, it is preferable that the strip width dimension E of the strip-shaped paper material 30 shall be 8 mm or more and 50 mm or less. If it is less than 8 mm, sufficient strength may not be obtained. In addition, even if it exceeds 50 mm, sufficient strength may not be obtained.

Then, the strip-shaped paper material 30 is alternately bent at about 90 degrees to form a triangular wave (zigzag). Furthermore, the phases of the triangular waves of the adjacent paper strips 30, 30 are different by about 90 degrees (about π / 2).
Adjacent strip-shaped paper materials 30 and 30 are fixed to each other by an adhesive and form a rectangular parallelepiped space 31 surrounded by the adjacent strip-shaped paper materials 30 and 30.
That is, the core material 3 has many (plural) rectangular parallelepiped-shaped space parts 31 formed of many (plural) band-like paper materials 30 and 30.

  As shown in FIG. 3, the rectangular parallelepiped space portion 31 includes a first long side wall portion 32A and a first short side wall portion 33A, which are formed of one of the band-shaped paper members 30 (first band-shaped paper member 30A), and It is surrounded by a second long side wall 32B and a second short side wall 33B formed of the other strip-shaped paper material 30 (second strip-shaped paper material 30B) adjacent to the one strip-shaped paper material 30A. In other words, the rectangular tube wall portion is formed of the first strip-shaped paper material 30A and the second strip-shaped paper material 30B.

  Further, the inner dimensions K32 (in the paper material longitudinal direction) of the first and second long side wall portions 32A and 32B are the respective inner dimensions (in the paper material longitudinal direction) of the first and second short side wall portions 33A and 33B. The dimension is set to 1.75 times to 2.5 times the dimension K33. If it is less than 1.75 times, the rectangular space 31 becomes narrow, which makes manufacturing difficult and reduces the weight reduction effect. If it exceeds 2.5 times, the rectangular space 31 becomes large, and the strength may be reduced.

The first long side wall portion 32A is mutually adhered to the third long side wall portion 32C of the adjacent strip-shaped paper material 30 (third strip-shaped paper material 30C) different from the second strip-shaped paper material 30B.
The second long side wall portions 32B are mutually adhered to the fourth long side wall portions 32D of the adjacent strip-shaped paper material 30 (fourth strip-shaped paper material 30D) different from the first strip-shaped paper material 30A.
The bonding site between the first long side wall 32A and the third long side wall 32C, and the bonding site between the second long side wall 32B and the fourth long side wall 32D are the respective long side walls 32A, 32B, About half of 32C and 32D is a double-walled structure which is overlapped and fixed (in the paper material longitudinal direction).
By forming such a double-walled bonding site Z, it is possible to exert sufficient strength against the force in the paper material band width direction (panel material thickness direction T).

Then, as shown in FIG. 1, the first inclined surface 11 formed on the edge 1 d of the first plate 1 so as to face the second plate 2 and the first plate 1 at the edge 2 d of the second plate 2. A band plate member 5 having a flat trapezoidal cross-sectional shape is fixed in a lid-like shape to the second inclined surface 21 formed to face the side.
The band plate material 5 has a first inclined surface 51 in contact with (in intimate contact with) the first inclined surface 11 and a second inclined surface 52 in contact with (in contact with) the second inclined surface 21. ing.

  The band plate material 5 is made of a veneer board, and the surface 5a on the outer surface side of the panel is waterproofed (waterproofed). Specifically, a membrane-like (sheet-like) waterproof layer formed of a resin such as vinyl is laminated. The waterproof treatment prevents water from entering the inside of the panel material and prevents warpage due to changes in temperature and humidity.

  The first plate 1, the second plate 2 and the strip plate 5 are made of the same plate material, and a pattern such as wood grain or a single color or pattern such as chromatic color or white or black is printed on a plywood (plywood) Laminated printed color plywood with fixed (pasted or bonded) decorative sheets, or direct printed color plywood printed directly with patterns, colors, etc., or vinyl chloride plywood or polyester decorative plywood Etc is desirable.

Next, the configuration of the panel material will be described together with the panel material manufacturing method of the present invention.
First, a core material manufacturing step of manufacturing the core material 3 is performed.
In the core forming step, a large number of waterproofed strip-shaped paper members 30 are alternately folded and disposed in a triangular wave shape, and the phases of the triangular waves of adjacent strip-shaped paper members 30 are different from each other to adhere to each other. Then, a core material 3 having a large number of rectangular parallelepiped space portions 31 formed by a large number of strip-shaped paper materials 30, 30 is produced.

After the core forming step, as shown in FIG. 4A, the first plate 1 with the surface 1a waterproofed, the core 3 and the second plate 2 with the surface 2a waterproofed, as shown in FIG. Are superimposed in the panel material thickness direction T, and an overlapping step of fixing with an adhesive is performed.
In the overlapping step, the rectangular parallelepiped space 31 of the core material 3 is closed by the back surface (inner surface) of the first plate 1 and the back surface (inner surface) of the second plate 2 to form a rectangular cavity. In addition, what the 1st board | plate material 1 and the core material 3 and the 2nd board | plate material 2 overlap and fix in the panel material thickness direction T may be called the panel intermediate 8 in some cases.

After the overlapping step, an edge processing step of cutting the edge 8d of the panel intermediate 8 is performed.
In the edge processing step, the panel intermediate 8 is horizontally fixed on a horizontal work table. And as shown in FIG.4 (b), the tool 62 for 2nd inclined surfaces is made to travel along the edge 2d of the 2nd board | plate material 2, and the 2nd inclined surface 21 is formed, and FIG.4 (c) As shown in the drawing, the first inclined surface tool 61 is caused to travel along the edge 1 d of the first plate 1 so as to follow the second inclined surface tool 62 to form the first inclined surface 11.

That is, when observed at a predetermined one point in the longitudinal direction of the edge 8 d of the panel intermediate 8 (the edges 1 d and 2 d of the first and second plate members 1 and 2), the second edge 2 d of the second plate 2 is After the inclined surface 21 is formed, the first inclined surface 11 is formed on the edge 1 d of the first plate 1.
Although not shown, the first inclined surface tool 61 (hereinafter also referred to as the first tool 61) may be run first (precedingly) to form the first inclined surface 11, while the second The inclined surface tool 62 (hereinafter also referred to as the second tool 62) may be driven to follow to form the second inclined surface 21.

Thus, by fixing the panel intermediate body 8 and running the first and second tools 61, 62, the first and second inclination angles α1, α2 of the first and second inclined surfaces 11, 21 and , The relative position can be matched with high accuracy.
Moreover, the cutting conditions of the first inclined surface 11 and the cutting conditions of the second inclined surface 21 can be individually adjusted by not processing the first inclined surface 11 and the second inclined surface 21 simultaneously with one tool. Each of the first inclined surface 11 and the second inclined surface 21 can be finished with high accuracy.

  A first inclination angle (an angle between the surface 1a of the first plate 1 and the first inclined surface 11) α1 and a second inclination angle (the surface 2a of the second plate 2 and the second inclined surface 21) The angle α2 is preferably 30 degrees or more and less than 60 degrees. If it is less than 30 degrees, edge processing becomes difficult. If the temperature exceeds 60 degrees, the strip plate 5 is easily detached and the manufacture becomes difficult. Preferably, it is about 45 degrees.

  In the edge processing step, the (one) edge 8d to be processed of the panel intermediate 8 is disposed in correspondence with the tool travel planned area of the first and second tools 61 and 62, 2) Form the inclined surfaces 11, 21 and release the fixation of the panel intermediate 8 and arrange the other edge 8d of the panel intermediate 8 to be processed corresponding to the above-mentioned tool travel expected area It fixes and forms the 1st * 2nd inclined surface 11 and 21 similarly about the other edge 8d. The edge processing is desirably performed over the entire circumference of the panel intermediate 8 (at all the edges 8 d).

Then, after the edge processing step, as shown in FIG. 4 (d), a strip plate material having a flat trapezoidal cross section at the edge 8 d of the panel intermediate 8 on which the first and second inclined surfaces 11 and 21 are formed. Then, as shown in FIG. 4 (e), a panel end face forming step of fixing the strip plate 5 to the panel intermediate 8 is performed.
The first inclined surface 51 of the band plate 5 and the first inclined surface 11 of the first plate 1 are brought into contact with each other in a planar manner and adhered, and the second inclined surface 52 of the band plate 5 and the second inclined surface 21 of the second plate 2 Are brought into contact with each other in a planar manner and adhered, and the band plate material 5 is adhered to the edge 8 d of the panel intermediate 8 in a lid-like manner.

The band plate material 5 is adhered to all the edges 8d of the panel intermediate 8 subjected to edge processing, and the panel end face forming process is completed. As shown in FIG. 4 (e), the surface 5a of the strip plate 5 is the end face of the panel.
The bonding of the panel intermediate 8 and the strip plate 5 by bonding of the slopes by the first and second inclined surfaces 11 and 21 of the panel intermediate 8 and the first and second slopes 51 and 52 of the strip plate 5 When viewed from the front side (in appearance), the border is a ridge line portion where the panel plane and the panel end face are in contact in the completed panel material, the border is inconspicuous, and the appearance is excellent. In particular, while the first and second inclined surfaces 11 and 21 are formed with high accuracy by the above-described processing method, the first and second inclined surfaces 51 and 52 have high accuracy dimensions in the strip plate material 5 having a small and simple shape. As a result of the formation and the bonding being performed precisely and precisely in accordance with each other, the ridges (boundaries) look like the ridges of a single plate.

In addition, as long as it is before the panel end face forming step, the band plate manufacturing step of manufacturing the band plate 5 may be performed at any timing before and after the edge processing step.
In the band plate producing step, the end edge (along the longitudinal direction of the band plate material) of the inner side of the band plate material having a flat rectangular shape in cross section is cut into a chamfered shape, and the other end on the inner surface side of the band plate material The edge is cut into a chamfered shape to produce a band plate material 5 having a flat trapezoidal cross section.

  Further, as in the other embodiment shown in FIG. 5, in the edge processing step, the edge 8 d of the panel intermediate 8 may be cut into a W shape. Compared with the case where the edge 8d of the panel intermediate 8 is cut into a V shape as shown in FIG. 4, the cutting range (removal range) of the core material 3 is smaller and the strength of the panel material edge is Excellent. In addition, cutting powder (garbage) during production is also reduced. Other configurations and effects are the same as the embodiment of FIGS. 1 to 4.

  The present invention can be changed in design, and the panel material of the present invention is not limited to the rectangular plate type as shown in the figure, and is free, such as triangular type or polygonal type.

And the plurality of rectangular parallelepiped space portions 31 formed by the plurality of strip-shaped paper members 30 and 30 in a state of being mutually fixed to each other, and further, the first plate is directed to the second plate 2 side. The first inclined surface 11 formed at the edge 1 d of the plate 1 and the second inclined surface 21 formed at the edge 2 d of the second plate 2 so as to face the first plate 1 Since the flat plate-shaped band board 5 made of a plywood board is fixed in a lid-like manner, the panel 1 is made of the first board 1, the second board 2 and the band board 5. It is possible to obtain a sufficient strength surrounds the outer surface side in a frame shape. Sufficient strength can be obtained while making the inside of the panel into a lightweight paper core 3, and deflection can be prevented. The core material 3 does not absorb water (moisture) in the air, and can be prevented from warping (deformation) without being adversely affected by changes in temperature and humidity. It can be manufactured easily (inexpensive). It is lightweight while maintaining sufficient strength, and it can be used for various things such as shelf boards, partition walls, doors, ceiling panels, floor panels, etc., and it is easy to use (excellent versatility). Moreover, since it is lightweight, when it uses for doors, such as an entrance and a closet, a partition wall, a ceiling panel, etc., an assembly | attachment becomes easy. Moreover, it is suitable as a shelf board of a product shelf with many changes of a load and a layout change. In addition, the boundary between the first and second plate members 1 and 2 and the band plate member 5 is hardly noticeable and the appearance is excellent.

  Further, according to the panel material manufacturing method of the present invention, a large number of waterproofed strip-shaped paper members 30, 30 are alternately folded in a triangle wave shape, and the phases of the triangle waves of the adjacent strip paper members 30, 30 are arranged. Forming a core material 3 having a plurality of rectangular parallelepiped space portions 31 formed of a large number of the above-mentioned strip-like paper materials 30 and 30 by making them different from each other and forming a core material 3; And an overlapping step of overlapping and bonding the core member 3 and the second plate member 2 made of a veneer board, and after the overlapping step, the second plate member 2 side of the edge 1 d of the first plate member 1 An edge processing step of forming the first inclined surface 11 so as to face the second plate 2 and forming the second inclined surface 21 so as to face the first plate 1 side on the edge 2 d of the second plate 2; The first inclined surface 11 of the plate 1 and the second inclined surface 21 of the second plate 2 Since the panel end face forming step of bonding the flat plate-shaped veneer board band plate 5 is provided, it is lightweight while maintaining sufficient strength, and is used for various things such as shelf board, partition wall, door, etc. It is possible to obtain a user-friendly (very versatile) panel material that can be used. It is possible to easily (expensively) manufacture a panel material that is less susceptible to adverse effects due to changes in temperature and humidity and less likely to warp (difficult to deform). In particular, it is possible to obtain a panel material suitable as a shelf board of a product shelf in which changes in the load and layout changes are frequent. It is possible to manufacture a panel material excellent in an aesthetic appearance in which the boundary (boundary) between the first and second plate members 1 and 2 and the band plate member 5 is not noticeable.

  Further, in the end edge processing step, the end edge 1 d of the first plate material 1 is cut using the first inclined surface tool 61 to form the first inclined surface 11, and the end edge of the second plate material 2 Since the second inclined surface 21 is formed by cutting 2 d with the second inclined surface tool 62 different from the first inclined surface tool 61, the cutting conditions of the first inclined surface 11 and the second inclination The cutting conditions of the surface 21 can be adjusted individually, and cutting can be performed beautifully, with high precision, and efficiently.
