Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to decorative plywood having a three-dimensional pattern.

Conventionally, decorative veneer veneers cut from raw wood are shaped into shapes formed by combining straight lines, such as triangles, rectangles, squares, trapezoids, and rhombuses, and multiple pieces of these veneers are assembled without gaps. Decorative plywood has existed, which is made by arranging and pasting onto a substrate such as plywood. However, the main focus of these decorative plywood designs is the grain, color tone, etc. of the decorative veneer veneer, and by shaping it into a predetermined shape as described above, the natural feel of the veneer veneer can be achieved. The existence of artificial artifacts using linear geometric patterns is also clearly visible in the designs, and the repetition of such linear geometric patterns tends to result in a monotonous and uniform design as a whole.

Furthermore, it is clear that the arrangement of decorative veneer veneers with no gaps not only impairs the three-dimensional appearance of decorative plywood, but also makes the manufacturing process extremely complicated. Raw wood with grain, color, etc., that is, raw wood called precious wood, is becoming depleted around the world, so the cost of producing it is inevitably rising, and the current situation is that it is losing marketability. be.

On the other hand, when veneer veneers are sequentially cut from logs, at the beginning of cutting, a large number of veneer veneers are cut that have irregularly shaped parts at least on the periphery. ) are all discarded as so-called scrap veneers, and only those with a desired width or larger are cut off the irregularly shaped parts around them, shaped into the desired size and shape, and made into plywood.・
It is a well-known fact that it is used for decorative banner boards and the like. Also, in order to avoid cutting veneer veneers that do not have the desired width, there is a method in which irregularly shaped parts are removed and discarded from the raw wood in advance, the wood is processed into a regular shape, and then the veneer veneers are sequentially cut. In any case, the amount of wood that is discarded is enormous, resulting in a waste of valuable wood resources.

The undeveloped IJ1 is made of veneer that is cut directly from logs and is made up of various outer circumferential curves, and because of its irregular shape, we focused on the fact that it gives a more natural feel. The structure consists of multiple pieces of veneer veneer that have unshaped parts cut from logs on at least part of the periphery, such as peeled veneers or edged veneers, and a board. The reason is that it was pasted on the board surface.

The decorative plywood constructed in this way is completely different from conventional decorative boards, and has a non-uniform and three-dimensional effect both partially and as a whole, and has a novel design. There is no need to paste decorative veneer veneers without any gaps, which is considered to have excellent design, as in the past, and the surface can be made of peeled veneers or edged veneers, which were previously discarded as scrap veneers. Because you can! The A construction cost is significantly lower, and its marketability is much better than that of the conventional method.

In addition, top peeled veneer refers to the veneer that is cut before the raw wood becomes a perfect circle when the raw wood is cut with veneer lace. If a veneer or raw wood that does not have a predetermined length is cut with a veneer slicer after cutting, it is also called a ri board that is less than the predetermined length.

The unexploited plywood 1j will be described in detail below along with an example of its implementation illustrated in the drawings. FIG. The decorative plywood 1 has a plurality of peeled veneers 3, which are unshaped veneer veneers, having irregularly shaped portions 3a cut from logs in at least a part of the periphery, and a plurality of peeled veneers 3, which are made of, for example, plywood. They are dispersively arranged and attached to the surface of 2.

As is clear from the figure, since a plurality of peeled veneers 3 are attached to the surface of the substrate 2, not only a three-dimensional effect but also the shape of the irregularly shaped portion 3a on the outer periphery exhibits a natural curved pattern. ,
It exudes a sense of natural beauty. Also, if the top-peeled veneer 3 is attached with its surface facing the front side as in the illustrated embodiment,
The skin of the raw wood remaining on the irregularly shaped portion 3a can be used as a pattern, and a stable adhesion state can be maintained. In particular, the epidermis increases its natural feel,
Moreover, its dark curves harmonize with the white wood grain of the veneer veneer, creating a nice accent.

Figures 2a to 2f show examples of unshaped veneer veneers that are attached to the board surface, and Figure 2a shows scale-shaped,
Fig. 2 shows a cloud shape, Fig. 2 C shows a bamboo shoot shape, Fig. 2 d shows a chevron shape, and Figs. 2 e and 2 f show a drum shape. Such unshaped veneer veneers are often cut as top-peeled veneers, and therefore, in most cases, the skin of the raw wood remains at least in part around the periphery. Since the raw wood is round, the skin remains only on the outside of the raw wood, that is, on the front side of the veneer veneer, and since the skin is sloped, the cross-sectional shape of the veneer veneer is approximately It is formed into a trapezoid shape.

Therefore, when such a veneer veneer is attached to a substrate, if the surface of the veneer is attached to the front side, the skin can be used as a natural pattern, and the sloped part of the skin can be attached to the substrate. It also creates a sense of unity and three-dimensionality,
Moreover, the adhesion state is also stable.

Figures 3a to 3d show other embodiments of the decorative plywood according to the present invention. Figure 3 shows scale-shaped veneer veneers and bamboo shoot-shaped veneers arranged and attached alternately, and Figure 3 C shows cloud-shaped veneer veneers arranged and attached in two rows in a dispersed manner. , FIG. 3 d shows a structure in which the veneer veneers are partially overlapped and arranged and attached so that the surface of the board is not exposed. In this case, a veneer with an hx value is used as an unshaped veneer, but an end-scale veneer may be used in place of these double-peel veneers.

Although the present invention is constructed as described above, the manufacturing process of the present invention will be briefly explained next.

FIG. 4 is a block diagram showing an example of the manufacturing process of the present invention. First, an unshaped veneer veneer cut by a cutting device such as a veneer lace or a veneer slicer is dried in a drying device. , applying adhesive to one side of the unshaped veneer veneer using a gluing device that applies glue only to one side, and finally arranging the adhesive appropriately on the board surface by hand;
Pressure is applied using a press.

In addition, during the manufacturing process, the drying process can be omitted, and furthermore, during the cutting process to the arrangement and pressing process,
In some cases, we may add a cutting process where a part of the unshaped veneer veneer is cut as necessary, or a surface treatment process such as applying sump or applying varnish to the laminated decorative plywood.
These changes, omissions, and additions to the manufacturing process do not change the gist of the present invention at all.

Since the wood panel 1 is constructed as described above, the shape of the unshaped portion of the veneer veneer can be effectively used as a pattern for the decorative plywood. Furthermore, since the unshaped veneer veneers are laminated and adhered to the substrate, a height difference occurs between the substrate surface and the unshaped veneer veneer surface, creating a three-dimensional effect. On the other hand, if the decorative plywood is used as a concrete panel, a three-dimensional pattern can be formed on a poured concrete wall, and the degree of use of the present invention is great.

Furthermore, regarding the manufacturing process, there is no need to select only decorative veneer veneers with excellent surface grain, color tone, etc., as with conventional decorative plywood, and it is not necessary to select only decorative veneer veneers with excellent surface grain, color tone, etc.; It saves you the trouble of arranging everything everywhere,
It is possible to simplify the manufacturing process and reduce manufacturing costs.
