Abstract

PURPOSE:To manufacture a building panel with good yield while easily forming an arbitrary design such as a curved line, by carving a groove in the surface of a thin wooden board to apply a predetermined design. CONSTITUTION:Grooves 3 are carved in the surface of the thin wooden board 2 bonded to the surface of a base material 1 to form circular designs. The carving of the grooves 3 can be performed by an NC rooter or a band rooter and may be performed before or after the bonding of the thin wooden board 2 but, in order to perform stable rooter work, said carving is pref. performed after the bonding of said board 2 to the base material 1. Since the grooves are carved in the thin wood board to form the design, an arbitrary design can be formed and, since the designs are formed by the grooves, a three- dimensional feeling is imparted. Since there is no loss in the thin wooden board to be used, yield is not lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a method of manufacturing building boards used for flooring, walling, ceiling materials, etc.

[Conventional technology]

Various wood members are used for flooring, wall, ceiling, etc. As the wooden member, a base material (such as plywood) with a thin wooden board attached to the surface is usually used.

[Problem to be solved by the invention]

Traditional designs for wooden components are mostly made of straight lines that are parallel or perpendicular to each other, and they are rarely designed with straight lines that intersect at an angle or with curved lines, so the design tends to be monotonous. Ta. This is because designs using diagonal straight lines pose numerous problems (productivity, yield, etc.) in the manufacture of building boards, and curves in particular are almost impossible to manufacture.

Therefore, an object of the present invention is to provide a method for manufacturing building boards that allows arbitrary designs such as curves to be easily created and that has a high yield.

[Means to solve the problem]

The method of manufacturing a building board according to the present invention involves carving grooves on the surface of a thin wooden board to form a predetermined design.

As the thin wood board, either circular porous materials (Nara, Tachi, Zelkova, etc.) or diffuse porous materials (Misume, Beech, etc.) can be used, and the appropriate thickness is about 0.2 to 10 mm. .

[Effect]

According to this invention, since the design is formed by carving grooves on a thin wooden board, any design can be created, for example, any shape such as a circle, a triangle, a diamond, a flower shape, a star shape, a curved line, or a straight line. design is possible. Also, since it is formed with grooves, it has a three-dimensional design.

Furthermore, since there is no loss in the wood thin plates used, there is no reduction in yield.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 3.

That is, in this embodiment, as shown in FIG. 1 and FIG.
was engraved to create a circular design.

The groove 3 can be carved using an NC router, a hunt router, or the like. Although the grooves 3 may be carved either before or after the thin wood board 2 is bonded, it is preferable to carve the grooves 3 after bonding the thin wood board 2 to the base material 1 in order to perform stable router work.

In this case, as shown in FIG. 3, the depth of the groove 3 may be a depth that does not reach the base material 1 (FIG. 3(A)), or may be a depth that reaches the base material 1 (FIG. 3(A)). Figure (B)).

The shape of the groove 3 is not particularly limited, and any shape can be adopted.

Furthermore, if the surface is colored with a coloring agent after the grooves are processed, the design becomes even more 3-dimensionally confusing.

If a circular hole material is used for the thin wood board 1, the wood grain can be emphasized, while if a scattered hole material is used, the design by the grooves 3 will be emphasized.

〔Effect of the invention〕

According to this invention, since the design is formed by carving grooves in the thin wooden board, any design can be created, and since it is formed with grooves, it has a three-dimensional effect. Furthermore, since there is no loss in the wood thin plates used, there is no reduction in yield.
