Abstract

(57) [abstract] (with correction) [PROBLEMS] A knot hole processing of the veneer on the front and back surfaces of the plywood is performed at low cost, and the relationship with the surface pattern of the veneer surface is not uncomfortable and is visually observed in a natural state. Provide a plywood joint structure that can be done. A joint structure (a) of a plywood is provided with a putty (5) filled in a knot hole (4) having a knot on one surface in a plywood (2) having a veneer (1) bonded to the front and back surfaces and a pattern (3) arranged on one surface. Then, an artificial pattern 6 that conforms to the index pattern is engraved on the surface of the putty 5.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention belongs to the field of special processing of plywood.

[0002]

[Prior art]

 Conventional knot hole processing for plywood using veneer as the front and back surface materials is to process the knot hole into a circular shape and fit a repair material of the same shape into the hole and process it. There is no problem if the relationship between the ground pattern and the repair material is not questionable, but when surface finishing is used to make a high-end product, the relationship between the pattern and the knots is noticeably noticeable and uncomfortable. It happened. In addition, it was costly to make a repair material that had the same shape as the knotted hole.

[0003]

[Problems to be solved by the invention]

 In view of the above, according to the present invention, the knot hole processing of the veneer on the front and back surfaces of the plywood is performed at low cost, and the relationship with the pattern of the veneer surface is not uncomfortable, and the plywood of the plywood which is visually observed in a natural state. It provides a knot structure.

[0004]

[Means for Solving the Problems]

 The joint structure of the plywood according to the present invention is such that, in a plywood having a veneer bonded to the front and back surfaces and an exposed pattern provided on at least one surface, putties are filled in the knot holes where the one side of the node is missing. An artificial pattern adapted to the above-mentioned pattern is engraved on the surface.

[0005]

[Embodiment of the invention]

 Knot holes with no knots are selected from natural ones, with a part of the contour of the lower surface enlarged slightly larger than the contour of the upper surface, and the artificial pattern is the same as the exposed pattern. From the ones that are not conscious of the knots, general knot patterns that are conscious of the presence of the knots are also selected.

[0006]

【Example】

 The present invention will be described with reference to an embodiment. As shown in FIG. 1, in a 5-ply plywood 2 in which a veneer 1 is adhered to the front and back surfaces, a veneer pattern 3 is applied to the veneer 1 on the front side, and FIG. Thus, the putty 5 having a color tone similar to that of the veneer 1 is filled in the knot hole 4 where the knot has been removed and dried, and the artificial pattern 6 having a ring-shaped pattern along the ledge contour 6 which is adapted to the ledge pattern 3 on the surface. Is engraved.

[0007] The joint structure a of the plywood thus formed (hereinafter simply referred to as joint structure a), when filling the putty 5, as shown in FIG. For example, the node hole 4 is partially expanded in a divergent shape toward the lower surface of the veneer plate 1, or an appropriate hole 7 indicated by an imaginary line is dug in the lower layer plate to improve the adhesion of the putty 5. Consideration is also given to bonding technology.

The artificial pattern 6 shown in FIG. 4 resembles a natural knot, and in this case, is seen as a real knot.

As described above, according to the knot structure a, the putty 5 to be filled is adapted to the contour of the knot hole 4 and integrated therewith, so that the pressing process is performed at a low cost and the engraving of the artificial pattern 6 is also performed. This can be simplified by using a die, and therefore, in the surfaced material 8 of the plywood 2, the joints can be expressed in a very natural state with the joints as wood grain or with the joints as joints. It can maintain high-grade products and contribute to expanding the use of plywood in a wide range such as interior materials, floor materials, ceiling components, and exterior materials. In addition, the technology of the present invention can be applied to one piece of the facing material 8 other than the plywood on the assumption that the backing material is used.

[0010]

[Effect of the invention]

 According to the present invention, since the knot hole processing is performed at a low cost including the provision of the artificial pattern in the surfaced material using plywood, and the artificial pattern is adapted to the surfaced pattern, It can be visually observed without discomfort, maintains the high quality of plywood at low cost, and has the effect of contributing to expanding the use of plywood.
