Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a decorative board that is used as a material for furniture or fittings when used as a construction material, such as an interior or exterior wall board for a building.

[Prior Art] Conventionally, among the above-mentioned decorative boards, decorative boards mainly used for interior walls are made by pasting a resin sheet with wood grain, etc. printed on the surface of various boards such as plywood, particle board, or gypsum board. What he wore is generally known. In addition, decorative laminates mainly used for exterior wall panels include those with grooves formed on the surface of flat plate-like plates, or those with many plates on the wall surface, one end of which is placed at the required interval on the surface of the decorative laminate. It is generally known that there are steps formed by nails nailed into the shape of armor stacks.

[Problems to be Solved by the Invention] However, among the above-mentioned conventional decorative laminates, the surface of the former is formed exclusively in a flat state, so it lacks a three-dimensional effect and has a problem of poor design effect. had.

In the case of the latter, for the same reason as the former, many plates were nailed into a stacked shape on the surface of a flat plate for the same reason as the former. In addition, the work efficiency of arranging a large number of plates is poor, and gaps are formed between the planar wall surface and the edge of the plate to be nailed, resulting in poor thermal insulation as a structural material. However, there were problems with the airtightness and durability required for exterior wall panels, such as sound insulation and moisture proofing.

[Object of the Invention] In view of the above-mentioned conventional drawbacks, the object of the present invention is to create a long plate whose front surface has a step-like three-dimensional effect and whose back surface has excellent flatness by using a relatively narrow plate. The purpose of the present invention is to provide a decorative board that has high production efficiency and workability, and has excellent functionality as a structural material.

Means for Solving Problem E] For this reason, the present invention is formed by laminating and bonding a large number of relatively narrow plates of a required length in a required inclined state to form a long plate, and the surface One end of each plate appears in a stepped shape at an arbitrary interval, and the other end of each plate, which is cut into a scarf shape according to the inclined state on the back side, is spaced at a desired interval. The decorative board is composed of mutually continuous planar shapes.

[Function of the Invention] According to the present invention, a large number of plates each having at least one end cut into a desired scarf shape and each having a relatively narrow width and a desired length are laminated and bonded in a desired inclined state. A long decorative board is formed by this.

On the front side of this decorative board, the ends of each plate appear in a step shape with arbitrary intervals, and on the back side, the other end of each plate is cut into a scarf shape according to the slope. They are arranged in a continuous plane shape with the required spacing. As a result, the back side has excellent flatness, so when it is installed on a wall, it can be easily positioned relative to the wall, and it is easy to install. Because it is shaped like a step in the relationship, it has a three-dimensional effect and has an excellent design effect.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

(First Example) In FIG. 1 schematically showing a decorative board made of veneers, the decorative board 1 is made up of a number of veneers 3 having a required length 11 in the fiber direction and a thickness t. The fibers of each veneer 3 are laminated and bonded so that the thickness thereof becomes T at a required inclination angle θ and with the fibers of each veneer 3 oriented substantially horizontally as shown in FIG. On the surface of the decorative board 1, the end portions 3a of each veneer 3 appear in a step shape with a required interval 12 according to the inclination angle θ, and on the back surface, the cut end portions 3b of each veneer 3 appear. A scarf-shaped cut surface 3C cut at the inclination angle θ with respect to the thickness direction of the veneer 3 is formed in a planar shape that continues in the horizontal direction as shown in FIG. When configuring the decorative board 1 using veneers 3 having approximately the same thickness, the thicknesses T, t, the length 11, and the spacing 1
2, the relationship 12 = (11·t)/T holds true. Incidentally, when forming the decorative board 1, the spacing 12 and the thickness t are usually selected depending on the design effect, and the thickness T and the length 11 are selected depending on the material used, the application, economic value, etc.

In FIG. 2 showing a continuous manufacturing method for the decorative laminate 1 configured as described above, the length in the fiber direction is the required length 2fil.
The end 3a (front end shown in FIG. 2) of the next veneer 3 is aligned in the 1MN direction with respect to the upper surface of the end 3a (rear end shown in FIG. 2) of the veneer 3 having a thickness of t. After sequentially stacking the veneers 3 with a width corresponding to the interval 12, an adhesive application device 5 is applied to the upper surface of the veneer 3 where the end portions 3a are stacked with each other, taking into account the influence on the cutter when cutting into parts, which will be described later. Adhesive 7 is applied. At this time, since the end 3a of the preceding veneer 3 is overlapped with the end 3a of the next veneer 3 with a width of 12, the end 3a of each veneer 3 (as shown in FIG. rear end shown)
An unapplied portion 7a of adhesive 7 is formed on the upper surface. Each of the veneers 3 to which the adhesive 7 has been applied as described above is laminated and bonded with the end portions 3a of the veneers 3 in a predetermined inclined state with their ends 3a offset from each other by the interval 12. That is, a large number of stepped portions 9a are formed on the conveying surface of the conveying device 9 shown in FIG. The end 3a (lower end shown in FIG. 2) of the veneer 3 is placed. Then, by transporting these veneers 3 in the direction of the solid line arrow shown in FIG. 2 while sequentially engaging the end portion 3a of each veneer 3 with the stepped portion 9a, each veneer 3 is adjusted to the required inclination angle θ. are laminated. Each of the laminated veneers 3 is laminated and bonded by a pressing device 11 disposed on the downstream side of the conveying device 9 in the conveying direction to such an extent that the above-mentioned inclined state can be maintained during divisional cutting to be described later. In addition, when laminating and bonding the veneers 3 to each other, a heat press machine is used instead of the cold press type press machine 11 to harden the adhesive 7, and the veneers 3 are laminated and bonded to each other. As shown in the figure, the plate component 13 in which each veneer 3 is laminated and bonded is cut by a cutting device such as a cutting knife, a band saw, a razor, etc., which is disposed below the conveyance direction of the conveyance device 9! 15, the decorative board 1 is formed by dividing each veneer 3 on the top and bottom surfaces of the board component 13 at an appropriate intermediate part of the thickness, leaving the ends 3a, in a direction perpendicular to the thickness. Ru. Incidentally, the veneer 3III may be temporarily bonded and then cut to a required length, bonded by batch-type cold pressing or hot pressing, and then cut into parts. As described above, this decorative board 1 has the edges 3a of each veneer 3 stepped in the shape of steps spaced apart by the distances 2 on the front surface, and the cut surfaces 3C formed by the above-mentioned divisional cutting on the back surface. 'It appears in a continuous plane in the horizontal direction.

The surface of the decorative board 1 having the above structure is the end 3a of each veneer 3.
Since the laminates are arranged in a step shape with an interval of 12, it has a three-dimensional effect and can enhance the design effect compared to conventional printed decorative laminates or decorative laminates in which appropriately shaped grooves are provided on the surface of the decorative laminate. . Furthermore, since the back surface of the decorative board 1 is formed in a horizontally continuous plane, the decorative board 1 can be easily positioned when attached to a wall surface, and workability can be improved.

(Second Example) The third example schematically shows a decorative board with a cut pattern formed on the surface.
In the figure and FIG. 4 showing the divided cutting state, the decorative board 21 on which the cut pattern is formed has the required length 11 in the fiber direction.
, and an arbitrary number of cuts 23b having a thickness of t and having a length corresponding to at least the required interval 12 from the end in the iam direction from the end 23a are formed in the aug orthogonal direction, and the other end 23C, the distance 12 and the thickness t
The fibers of each veneer 23 are oriented in the substantially horizontal direction shown in FIG. 3, and the thickness is T at the required inclination angle. Laminated and glued so that The decorative board 21 has, on its surface, the ends 23a of each veneer 23 in a stepped shape with the interval 12, and the notches 23b formed in the end 23a of each veneer 23 are adjacent to each other. It is formed in a stepped cut pattern that reaches the end portion 23a of the veneer 23. Further, on the back surface of the decorative board 21, the cut surfaces 23d of each of the veneers 23 are formed in a planar shape that continues in the horizontal direction as shown in FIG.

Note that the notch 23b formed in the end 23a of each veneer 23
When each veneer 23 is laminated and bonded at a required inclination angle θ, a required stepped cut pattern is formed that is discontinuous, continuous, or partially continuous with respect to the cut 23b of the other adjacent veneer 23. The fibers are arranged in the direction perpendicular to each other. Further, the length of the cut 23b in the fiber direction of each veneer 23 is formed according to the interval 12 so that the end of the cut 23b is located at the end of the end 23a of the adjacent veneer 23. However, the distance may be set slightly longer than the distance 12 so that the thickness between the back surface of the decorative board 21 and the end of the notch 23b does not affect the strength and quality of the decorative board 21. Furthermore,
The continuous manufacturing method of the decorative board 21 is the same as the manufacturing method of the first embodiment described above, except that the length in the fiber direction is 211, and the notches 25b are formed at both ends 25a in the relationship described above. Laminating a large number of veneers 25￥'ii＠
I. After forming the plate constituent material 27, each end 2 is attached to the front and back surfaces.
A decorative board 21 having a stepped cut pattern on the front and back surfaces is formed by dividing and cutting at an appropriate intermediate portion in the thickness direction (indicated by a broken line in the figure) leaving the portion 5a.

In addition, as mentioned above, when the length of the cut 25b in the mH force direction is set to the interval 12 or more, the thickness tl of the decorative board 21 according to the end of the cut 25b becomes a thickness that does not affect the strength of the decorative board 21. The plate component 27 is cut into parts.

(Third Example) In FIG. 5 schematically showing another decorative laminate using the decorative laminate 1 according to the first example as a base plate, and FIG. 6 showing the VTM state, the upper surface of the aforementioned decorative laminate 1 is has fibers in the direction that corresponds to the fibers of the decorative laminate 1, has a required length 13 in the II fiber direction, and has a thickness t.
1 are laminated and bonded so that one end 31a (the lower end shown in FIGS. 5 and 6) and the end 3a of each veneer 3 on the surface of the decorative board 1 engage with each other. decorative board 33
is formed. The length T3 of the front plate 31 may be at least longer than the interval 12, but is not particularly limited to the interval I2.

Further, the length 13 is appropriately set according to the thickness T1 of the decorative board 33 to be formed. That is, when forming a thick decorative board 33 using the decorative board 1 shown in the first embodiment, the length T3 is set longer than the interval 12. The end portion 31b of each top plate 31 has a large number of notches 31 having a length 14 in the fiber direction of at least the interval 12 or more.
C is formed in an array according to the step cut pattern formed on the surface of the decorative board 33 in the direction orthogonal to the m-fibers. The cut 3
The length 14 of 1G is the length in which the end surface 31d of the notch 31c reaches the end 31a of the adjacent top plate 31, and is therefore preferably the distance I2. In order to allow the end of the notch 31b to reach the end 31a even when the ends are aligned, the distance 1 is
It is set slightly longer than 2. Further, the arrangement of the cuts 31G in the direction perpendicular to the fibers is appropriately arranged according to the required stepped cut pattern formed on the surface of the decorative board 33, as described in the second embodiment. That is, for example, in order to form a decorative board 33 with a cut step pattern in which the cuts 31c are continuous on the surface, the cuts 31c formed in each adjacent top plate 31 are formed so that they are all continuous at equal pitches. .

The decorative board 33 formed as described above is thicker and has a three-dimensional effect than the decorative board 1.

In the above explanation, a large number of top plates 31 are laminated and bonded to the surface of the decorative board 1 so that the end portions 3a and 31a engage with each other. Modifications can be made by interposing various intermediate plates between 31 and 31.

As shown in FIG.
lli and has approximately the same thickness as the veneer 3 and the front plate 31, or is thin or thick.
It may be possible to intervene. In this case, decorative board 3
3 is formed with substantially the same structure as plywood, so it is possible to obtain a board with high board strength and little warpage, and the board thickness T of the decorative board 33 can be adjusted as appropriate according to the intervening intermediate board 35. You can. In addition, when interposing the intermediate board 35 between the decorative board 1 and the top board 31 in order to adjust the thickness of the decorative board 33, the fibers are placed in the same direction as the veneer 3 and the top board 31. It may be something that you have.

As shown in FIG. 8, there are fibers between the decorative board 1 and the top board 31 in a direction perpendicular to the fibers of the veneer 3 and the top board 31, and the length of 41 in the orthogonal direction is the interval 12. Alternatively, the narrow middle plate 37 having a length of 12 or more is connected to the end portion 3.
It may also be one that is successively interposed between a and the end portion 31a. In this case, compared to the decorative board 33 shown in FIG. 7, it is possible to use a narrower intermediate plate 37 to create a structure substantially similar to that of plywood. The composition ratio of can be adjusted. Note that the thickness of the middle plate 37 shown in FIG. 8 is approximately equal to that of the veneer 3 and the top plate 31, but the thickness of the middle plate 37 shown in FIGS. The plate thickness may be thicker or thinner than the veneer 3 and the front plate 31. As shown in FIG. 10(A), the intermediate plate 37 interposed between the decorative board 1 and the top plate 31 may have a length in the direction perpendicular to the m-fibers that is shorter than the interval 12. In this case, since the intermediate plate 37 is disposed in a divided state between the decorative laminate 1 and the top plate 31, the decorative laminate 33 using the one-piece intermediate plate 35 shown in FIG. Compared to the decorative board 33 using the intermediate plates 37 whose length in the direction perpendicular to the fibers is 12, etc., the intermediate plates 37 with a narrower width can be used to create substantially the same structure as plywood. 37 can be reduced, and a decrease in the adhesive strength of the decorative board 33 due to the back cracking of the intermediate plate 37 can be prevented. Further, as shown in FIG. 10(B), when forming the decorative board 33 using the intermediate plate 37 whose length in the direction perpendicular to the fibers is shorter than the interval 12, the end of the intermediate plate 37 (the upper end shown in the figure) ) and end 3
1a The decorative board 33 may be formed by laminating and bonding the decorative board 1 and the intermediate boards 37 and 31 to each other in such a manner that three gaps are formed between them.

In addition, Figures 8, 9 (A) and (B), and Figure 10 (A
)・(B) shows a decorative board 33 using an intermediate board 37 having IiN in the direction perpendicular to the fibers of the decorative board 1 and the top board 31, but the purpose of adjusting the thickness of the decorative board 33 is to or when performing woodworking, the veneer 1
Of course, it is also possible to use an intermediate plate having fibers in the same direction as the fibers of the top plate 31, or an alternately layered intermediate plate 37.

In addition, the decorative board 21 shown in the second embodiment and the third embodiment
and 33 are assumed to have the required step inset pattern, but even if the various step patterns shown in FIG. In this case, the spacing between the edges formed on the surface of the decorative board does not necessarily have to be the above-mentioned spacing 12.

In the description of the second and third embodiments mentioned above,
The decorative boards 21 and 33 are formed by sequentially laminating and bonding the veneer 23 and the top board 31 on the surface of the decorative board 1 whose end portions 3a are stepped in the horizontal direction with an interval of 12. A large number of veneers 2 are stacked with the end portions 23a and 31a shifted horizontally by 12 intervals and inclined at a required angle with respect to the thickness.
3 and the top plate 31 are laminated and adhered to the surface of the decorative laminate 1 according to the above-mentioned required relationship to form the decorative laminate 21.
There may be a method of forming 33.

In the above explanation, a long decorative board is formed using a narrow veneer as a board, but instead of the above veneer, sawn board, split board, particle board, medium-hard fiberboard, ceramic, etc. Decorative boards with excellent flatness on the back side and various step cut patterns on the front side can be formed using various types of boards such as wooden boards and gypsum boards.

In addition, when laminating a top board on the surface of the decorative board 1, the intermediate board interposed between the decorative board 1 and the top board is slightly shifted in a direction perpendicular to the fibers of the decorative board 1 to form rabbets and rabbets. A structure may be provided in which a recessed portion is provided.

[Effects of the Invention] Therefore, the present invention uses a plate body having a relatively narrow width, and the front surface has a step-like three-dimensional effect, and the back surface has a long shape with excellent flatness, which improves production efficiency and workability. It is possible to provide a thin decorative board.
