Abstract

PROBLEM TO BE SOLVED: To provide ligneous building material in which an overhanging part with arbitrary size is easily formed and the overhanging part is formed into accurately designed size in the ligneous building material, in which the overhanging part is formed of plate material. SOLUTION: At least three bending grooves (a)-(c) are provided on one side of ligneous plate material 5 and also a fitting groove (d) of the end part 5a of the plate material 5 is provided. The plate material 5 is bent along the bending grooves (a)-(c) and the end part 5a of the plate material 5 is fitted into the fitting groove (d). Thereby, the inside becomes space part (h) and an overhanging part 5c projected from the surface of the plate material is formed of this plate material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden building material in which an overhang is formed at an end of a wooden board, such as a vertical frame of a closet.

[0002]

2. Description of the Related Art As shown in a schematic plan view of FIG. 3 (A), a vertical frame of a closet hides a gap G between an end of a folding door 1 and a vertical frame 2 so that an outdoor side of the vertical frame 2 can be closed. An overhang portion 2a is formed over the entire length of the vertical frame 2 so as to protrude in the direction in which the vertical frames 2 face each other.

Conventionally, in order to realize such a planar shape, as shown in FIG. 3B, a portion surrounded by a dotted line 3 from a raw material 2X made of a plywood such as MDF having a square end surface shape, for example. Is removed by cutting, and then FIG.
As shown in (C), a resin-made decorative sheet 4 of wood tone or the like is stuck around.

However, in the case of the conventional vertical frame 2,
There is a problem that the influence of the warpage of the raw material 2x remains as it is, and the decorative sheet 4 must be adhered to the uneven surface of the vertical frame 2, and this poor adhesion is likely to occur,
As a result, there was a problem that the yield was poor.

In order to solve such a problem, as described in Japanese Utility Model Laid-Open No. 55-143316, a V-shaped groove is formed in a plate made of plywood, and the plate is folded along the V-shaped groove. It is conceivable to form an overhang.

[0006]

However, in the apparatus disclosed in Japanese Utility Model Laid-Open No. 55-143316, the overhang portion is formed by abutting the inner surfaces of three folded portions which are overlapped with each other. Therefore, the thickness of the overhang is determined by the thickness of the plate material, and an overhang of any width cannot be formed.

In view of the above problems, the present invention can easily form an overhang portion of any size in a wooden building material in which an overhang portion is formed by a plate material, and can form the overhang portion to a designed exact size. An object is to provide a wooden building material that can be formed.

[0008]

According to the present invention, at least three bent grooves are provided on one surface of a wooden board, and a fitting groove into which an end of the board is fitted is provided. The board is folded along the bent groove. Further, by fitting an end of the plate material into the fitting groove, the inside becomes a space portion, and a projecting portion projecting from the surface of the plate material is formed in the plate material.

[0009]

In the present invention, a bending groove and a fitting groove are provided in advance on a flat wooden board, and the wooden building material is bent along the bending groove, and an end of the board is fitted into the fitting groove and fixed. As a result, an overhang portion having a space inside is formed at the end. The fitting groove functions to position the end of the plate material, and the shape and size of the overhanging portion are set accurately.

[0010]

1 and 2 show one embodiment of a wooden building material according to the present invention. In manufacturing a vertical frame 2 of, for example, a closet shown in FIG. 3, as shown in FIG. A decorative sheet 4 made of a vinyl chloride resin or the like is pasted on one surface of a wooden board 5 made of plywood or the like such as MDF which has been cut into a predetermined width and length in advance, and the decorative sheet 4 of the wood board 5 is pasted. On the side not attached, the end view of FIG.
As shown in the plan view of FIG. 2C, V-shaped bent grooves a to c and a fitting groove d having a rectangular cross section at the end 5a.
And V-shaped grooves e and f for folding are provided over the entire length of the plate material 5 by cutting.

Next, as shown in FIG. 1A, an adhesive 6 is applied to the grooves a to f and the overlapping surface g and the like, and the bending grooves a, b and c are bent at right angles. As shown in B), the end 5a of the plate member 5 is fitted and fixed in the fitting groove d. Thereafter, the folded portion 5b on the other end side is folded back at the folding grooves e and f and overlaps and adheres to the overlapping surface g, so that the overhang portion 5c having a rectangular space portion h inside is provided.
Is produced.

Thus, according to this bending structure,
The decorative sheet 4 can be pasted on the flat plate material 5 in advance, so that the decorative sheet 4 can be easily pasted. Further, bending grooves a to c and a fitting groove d are provided so that the bending grooves a
In the structure (b) to (c), the end 5a of the plate 5 is fitted into the fitting groove d, whereby the tip of the plate 5 is accurately positioned, and the entire shape is accurately formed. Further, by changing the size of the space portion h variously, the size of the overhang portion 5c can be arbitrarily formed.

Further, since the tip of the plate member 5 is fitted and fixed in the fitting groove 5d, it is not necessary to hold the plate member 5 until the adhesive 6 is hardened. The portion 5b can be adhesively fixed. In the present invention, instead of using an adhesive, a fixing tool such as a screw or a nail is used in place of the adhesive or in combination with the adhesive as the main fixing means to the fitting groove d of the end portion 5a. You may.

In this embodiment, the folded portion 5
By providing b and making the portion other than the overhang portion 5c a double structure, it is possible to obtain the vertical frame 2 and the like having a thickness greater than the thickness of the plate material 5 as a raw material. The other end 5d of the plate member 5 is brought into contact with the overhang portion 5c, so that the adhesive 6
5b and overhang 5c before bonding by
Are pressed against each other and fixed to each other, so that the end 5a of the plate member 5 is more reliably prevented from falling out of the fitting groove d in a temporarily fixed state before bonding.

Although the present invention has been described with reference to the embodiments, the shapes of the bent grooves a to c and the fitting grooves d are not limited to the above-described embodiments, and can be variously changed.

[0016]

According to the present invention, a space portion is formed in a portion surrounded by a bending groove in a wooden building material in which an overhang portion is formed at an end portion by a plate material. Can be easily formed, and the end portion of the plate material is fitted into the fitting groove and positioned, so that it is possible to form a projecting portion having a designed and accurate shape and size.
