Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a decorative board having a dowel-like pattern, which is used as a decorative board for construction such as flooring and wall materials.

Conventionally, in order to obtain this type of decorative board, as shown in FIG. This method is manufactured by drilling a hole 60 that reaches the desired height, then fitting a dowel d into the hole C, and cutting the upper end of the dowel d protruding from the surface of the decorative veneer b. According to the company, not only did the production efficiency decline due to the large number of manufacturing steps, but the positions of the dowels on individual decorative boards were uneven, making it impossible to achieve uniformity of the product. In some cases, there was a drawback that the appearance was inferior.

In order to eliminate such drawbacks, the present invention has been developed by integrally bonding a decorative veneer with dowel-like patterns in predetermined portions on the top surface of the substrate, and then cutting grooves between adjacent dowel-like patterns. The present invention provides a method for manufacturing a decorative board having a dowel-like pattern.

To explain an embodiment of the present invention with reference to the drawings, dowel-like patterns 2, 2 are formed at the center of both longitudinal ends of a rectangular decorative veneer 1.
', and on the center line connecting these dowel-like patterns 2, 2', the dowel-like patterns 2, 2' are arranged at a predetermined interval in a part biased toward one dowel-like pattern 2 from the center in the length direction. A pair of dowel-like patterns 2at2a' of the same size and shape as 2'
shall be provided as necessary.

The distance between the dowel-like patterns 2a and 2a' is set to be twice the distance between the dowel-like patterns 2 or 2' provided from the end face to the end of the decorative veneer 1.

Next, this decorative veneer 1 is integrally bonded to the upper surface of a substrate 3 such as plywood with an appropriate adhesive, so that at least the substrate 3
A decorative board having dowel-like patterns 2, 2' near both ends is obtained.

At this time, if the shape of the upper surface of the substrate 3 and the shape of the decorative veneer 1 are the same as the elongated rectangular shape, one piece of the decorative veneer 1 can be pasted on the substrate 3 as shown in FIG. However, if the length of the substrate 3 is approximately the same as the length of the decorative veneer 1, and its width is several times, for example, three times, that of the decorative veneer 1, the substrate 3 as shown in FIG. Three decorative veneers 1 are pasted in parallel on top.

In this case, dowel-like patterns 2, 2' on both end sides of the decorative veneer 1
are located at both ends of the substrate 3, but a pair of dowel-like patterns 2a and 2a' provided toward the center from one dowel-like pattern 2 are arranged in a staggered manner in the width direction of the substrate 3. Attach the decorative veneers 1, 1, 1 as shown.

Such arrangement of decorative veneers 1 can be easily achieved by inverting every other decorative veneer 1 180 degrees in the plane direction with respect to the adjacent decorative veneers 1, 1.

After the decorative veneer 1 is bonded onto the substrate 3 in this way, the center portion between the pair of dowel-like patterns 2a+2a' is grooved in the width direction to form a joint 4, and the decorative veneer 1 is placed in close contact with each other. The side end surfaces of the joints 1 are grooved in the longitudinal direction to form joints 4', and the four sides are chamfered and processed as required.

The surface of the decorative board thus obtained is polished and then finished by applying an appropriate coating to the surface.

Further, FIGS. 5 and 6 show other embodiments of the present invention,
A large number of dowel-like patterns 2 are provided on both ends and the center of a single wide decorative veneer 1, which is then glued and integrated with the surface of a substrate 3 having the same size as the decorative veneer, as shown in FIG. An intermediate decorative veneer 1 is formed, and then grooves are formed in the width direction and length direction in the center between the dowel-like patterns 2 on the surface of the decorative veneer 1 to form joints 4.
was formed into a decorative board as shown in FIG.

After adhering the decorative veneer in this way, by creating grooves between the dowel-like patterns, it is possible to obtain a decorative veneer opening that looks as if a large number of decorative veneers with dowels were installed in series. It is.

Next, a method for obtaining the decorative veneer 1 having the aforementioned dowel-like patterns 2, 2', 2a, and 2a' will be explained. The method for obtaining the decorative veneer 1 having the dowel-like patterns 2, 2', 2a, and 2a' is as follows. This hole may be formed by fitting a pre-formed decorative veneer 1 with a dowel of a different color, or by burying an appropriate material, but as shown in FIG. By obtaining it from the wood fritsch 5, production efficiency can be further increased.

That is, circular holes 6, 6' of appropriate diameters penetrating between the front and back surfaces are bored in the center of both ends of the wood frit 5 using an appropriate drilling tool, and these circular holes 6, 6' are drilled as necessary. 6', a pair of circular holes 6a, 6a with the same diameter as the circular holes 6, 6' are located at a small interval in a part biased toward one circular hole 6 from the center in the length direction. '
Drill holes in the same manner.

The distance between the circular holes 5a, 5a' is set to be twice the distance between the circular holes 6 or 6' provided on the end face and end of the wood fritch 5.

In this way, the through circular holes 6, 6 are formed in the predetermined portions of the wood fritches 5.
After drilling ', 6a, 6a', these circular holes 6,
6', 6a, 6a', a rod-shaped body 7 having approximately the same length and shape as the circular hole is inserted into the inner surface of the circular hole 6, 6', 6a, 6a' or the rod-shaped body 7.
Apply appropriate adhesive to the outer circumferential surface of the wood flitch 5 and insert it into place.
Keep it buried inside.

The rod-shaped body 7 may be made of a different type of wood than the wood flitch 5, or the same type of wood with a different color, or a colored wood that is colored in a different color. You can use objects, carbon rods, etc.

Next, the rod-shaped embedded wood fritches 5 are cut into appropriate thicknesses (several mm) in a direction perpendicular to the longitudinal direction of the rod-shaped bodies 7 to obtain a plurality of decorative veneers 1.

The thus obtained decorative veneer 1 has dowel-like patterns 2, 2', 2a, 2a formed by rod-shaped bodies 7 cut at the same time as the cutting of the wood fritches 5 on both ends and near one end of the central part.
'.

As described above, the present invention forms a dowel-like pattern by embedding a material different from the decorative veneer into the holes provided at both ends and the center of the decorative veneer, and places the decorative veneer on the surface of the substrate. A dowel-like pattern characterized by placing the dowel-like pattern on a substrate so that the dowel-like pattern is located at the side edges and the center and bonding it together, and then forming grooves between adjacent dowel-like patterns. Since the decorative veneer has a dowel-like pattern in advance, it is easy to produce a decorative board with a dowel-like pattern by simply gluing the decorative veneer of Moreover, since the dowel-like pattern provided on the decorative veneer is arranged at a predetermined position on the substrate, the positional relationship of the dowel-like pattern on the decorative veneer obtained can be kept constant and the decorative properties can be improved. It is something that can improve.

In addition, by providing a plurality of dowel-like patterns on the ends and center of the decorative veneer, applying grooves after pasting it to the substrate, it looks as if a large number of decorative veneers with dowels were installed in a row. To obtain a decorative veneer with a wide design, which can give an appearance such as, and can give a three-dimensional and profound feeling by exposing the cut end face of the decorative veneer to the surface of the groove between the dowel patterns. In addition, since the dowel pattern is provided in all areas close to the groove end face and the end face of the decorative veneer, it effectively absorbs the expansion and contraction stress caused by changes in temperature and humidity in the dowel pattern area, preventing cracks in the area. This can prevent the occurrence of swelling, swelling, etc.
