Abstract

PURPOSE:To form pattern with highclass impression on the surface of the building material concerned with no necessity of the provision of a pattern groove, which increases the number of processes and causes the lowering of water resisting performance and moist heat performance. CONSTITUTION:Laminated flitch 4 is produced by pasting board material 2, which is thinner than wooden piece 1 and different in color from that of the wooden piece 1, between a plurality of the wooden pieces 1. Decorative veneer 5 is produced by slicing the laminated flitch 4 along the plane intersecting the plane, through which the wooden pieces 1 and the board material 2 are pasted together. The resultant decorative veneer 5 is pasted to board 1. Thus, the pattern 9 produced by pinching the board material 2, which is different in color from the wooden piece 1, between the wooden pieces 1 can be formed on the decorative veneer 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a building material such as a decorative plywood used for floor boards and wall panels.

[0002]

2. Description of the Related Art As a building material such as a decorative plywood used for floor boards and wall panels, there is one made by adhering a decorative veneer with an adhesive on a substrate. 3 (a) and 3 (b) show a floor board 7 used for a parquet flooring. This floor material 7 is obtained by bonding a decorative veneer 5 on a substrate 6 with an adhesive, as shown in FIG. ) As shown in FIG.
Is provided. The pattern groove 8 is created by adhering the decorative veneer 5 on the substrate 6 and then cutting it with a knife. By providing this pattern groove 8, an uneven pattern can be formed on the surface of the floor plate 7, You can finish it with a feeling.

[0003]

However, when the floor board 7 is manufactured as described above, the step of cutting the pattern groove 8 must be performed in another step after the decorative veneer 5 is bonded onto the substrate 6. Instead, the number of steps is increased by one step compared with the step of manufacturing the floorboard 7 in which the decorative veneer 5 is simply bonded onto the substrate 6. Further, if the cutting tool used for cutting is worn or chipped and the cutting performance is deteriorated, the pattern groove 8 is blunted, fluffed, or frayed to impair the appearance of the floorboard 7. Furthermore, since the floor plate 7 provided with the pattern grooves 8 is thinned at the pattern groove 8 and the substrate 6 is exposed, water easily penetrates through the pattern groove 8 or moisture or heat passes through. As a result, the water resistance of the floorboard 7 is deteriorated, and the floor heat cannot pass the JAS wet heat performance test.

The present invention has been made in view of the above points, and it is not necessary to provide a pattern groove that increases the number of steps or decreases water resistance and wet heat performance, and creates a high-quality pattern on the surface. It is an object of the present invention to provide a manufacturing method of a building material that can be manufactured.

[0005]

According to the method for manufacturing a building material according to the present invention, a plurality of wood pieces 1 having a thickness smaller than that of the wood piece 1 and a wood material 1 and a plate material 2 of a different color are attached to each other to form a flitch 4.
Characterized in that the laminated flitch 4 is sliced at a surface intersecting the bonding surface of the wood piece 1 and the plate material 2 to form a decorative veneer 5, and the decorative veneer 5 is bonded to the substrate 6. Is.

In the present invention, a single plate dyed with a dye can be used as the plate material 2.

[0007]

Function: A laminated flitch 4 is created by pasting the wooden piece 1 and a plate material 2 of a different color, which is thinner than the wooden piece 1 between a plurality of wooden pieces 1, and the assembled flitch 4 is used as a bonding surface of the wooden piece 1 and the plate material 2. Since the decorative veneer 5 is formed by slicing on the intersecting surfaces and the decorative veneer 5 is attached to the substrate 6, the pattern 9 formed by the different-colored plate materials 2 sandwiched between the wood pieces 1 is applied to the decorative veneer 5. Can be created.

[0008]

EXAMPLES The present invention will be described in detail below with reference to examples. Figure 1
In (a), an assembled flitch formed by attaching a plate material 2 which is thinner than the wood piece 1 and has a different color from the wood piece 1 to the peripheral side surface of the square wood piece 1 and further attaches the wood piece 1 to the outer periphery of the plate material 2. 4 is shown. As the wood piece 1, for example, oak wood can be used. The plate material 2 has a darker color than the wood piece 1, and for example, walnut material can be used. A single plate dyed with a dye may be used as the plate material 2, and for example, an Agatisu material dyed with a black dye may be used. The plate material 2 preferably has a thickness of about 2 to 3 mm. A urethane adhesive can be used to bond the wood piece 1 and the plate material 2. In many cases, the assembled flitch 4 is formed to have a width of 310 mm and a length of 610 mm, but the size is not limited to these, and the arrangement of the plate members 2 is limited as shown in FIG. 1 (a). It is not something that will be done.

Next, the assembled flitch 4 is sliced by a slicer to a thickness of about 0.3 mm at a surface that intersects the laminating surface of the wood piece 1 and the plate material 2 at a right angle, and a decorative veneer 5 as shown in FIG. To form. As the slicer, those for producing a normal veneer can be used, and examples thereof include a vertical slicer and a horizontal slicer. Then, the decorative veneer 5 is bonded onto a substrate 6 such as plywood with an adhesive, and heat-pressed to produce a building material as shown in FIG. 1 (c). In this product, a pattern 9 is formed on the surface by the dark-colored plate material 2.

In producing this building material, a pattern can be provided without cutting a pattern groove on the surface as in the conventional example described above. The surface can be patterned in the same number of steps as the material. In addition, since it is not necessary to form pattern grooves on the surface, there is no dip, fluffing, or blistering that does not impair the appearance, and the pattern part does not become thin, so water can easily penetrate. It does not drip or pass moisture or heat, the water resistance does not deteriorate, and it can pass the JAS wet heat performance test.

FIG. 2A shows another assembled flitch 4, which has a plate member 2 provided between a plurality of wood pieces 1. The assembled flitch 4 has a width of 310 mm and a length of 1.
The thickness is about 820 mm. The plate material 2 used here may have a thickness of about 1.5 mm. This assembled flitch 4 is sliced in the same manner as in the above-mentioned embodiment to obtain a slice as shown in FIG.
The decorative veneer 5 as shown in FIG. 2 is created, and the decorative veneer 5 is adhered and attached to the substrate 6 to form a building material as shown in FIG.

[0012]

As described above, according to the present invention, a laminated flitch is made by attaching a plate material having a thickness smaller than that of a wooden piece and a different color from that of the wooden piece to form a laminated flitch, and bonding the laminated flitch to the wooden piece and the plate material. Since the decorative veneer is formed by slicing on the surface that intersects with the surface and the decorative veneer is attached to the substrate, it is possible to create a pattern formed by different colored plate materials sandwiched between wood pieces on the decorative veneer. It is possible to create a high-quality pattern on the surface without the need to provide pattern grooves that increase the number of steps or decrease water resistance and wet heat performance.
