Description

Description: TECHNICAL FIELD The present invention relates to a method of manufacturing a wooden bathtub, and in particular, a method in which a side plate and a bottom plate facing each other of the bathtub are continuously formed by a single wooden plate. Regarding improvement.

(Prior Art) Conventionally, as a wooden bathtub, for example, as shown in FIG. 2 and FIG. 3, one wooden board 1 continuously forms side plates 2 and 2 and a bottom plate 3 facing each other in the bathtub. Then, the side surfaces of the wooden board 1 are formed into two side plates 5, each of which is a rectangular flat wooden board 4.
It is known that the wooden boards 1 and 4 are closed by 5 and each of the above wooden boards 1 and 4 is usually made of a cypress or the like on the inner surface of the laminated board 6 such as plywood or LVL in order to give off the scent of expensive wood. Makeup veneer 7
It will be attached. Reference numeral 8 is a frame member that connects the upper end portions of the side plates 5, 5.

The method of manufacturing the wooden bath, particularly the method of molding the wooden board 1 into a predetermined shape, has conventionally been performed by the following procedure. That is, first, the laminated plate 6 is adhered to the flat plate-shaped decorative veneer 7 at a portion between the side plate 2 and the bottom plate 3 of the bathtub except the corner portion. Next, the decorative veneer 7 is bent at a portion where the laminated plate 6 is absent (a portion corresponding to a corner portion of the bathtub) by using a male mold corresponding to the shape of the inner surface of the bathtub to form a substantially U-shape. After that, corner members 6b, 6b made of a laminated plate which is curved and formed in advance are adhered to a portion of the decorative veneer 7 where the laminated plate 6 does not exist.

(Problems to be Solved by the Invention) However, in this case, as the corner member 6b, when the plurality of veneers are laminated and adhered, one that is formed by laminating and adhering while bending each veneer is used. However, there is a problem in that the forming process is troublesome. In addition, when changing the bending angle and the radius of curvature of the corner portion of the wooden material 1, it is necessary to prepare a plurality of types of not only the male type but also the corner member corresponding to each type, which causes a problem in parts management and the like.

The present invention has been made in view of such a point, and the purpose thereof is to improve the molding method of the wood board, particularly to improve the molding of the corner member, and to improve the workability and the manageability of parts. It is intended to improve effectively.

(Means for Solving Problems) In order to achieve the above object, a solution means of the present invention is that a side plate and a bottom plate facing each other are formed by a single wood board made by sticking a decorative veneer to a laminated board. Among the methods for manufacturing a wooden bathtub that are continuously formed, the following configuration is used as a method for forming a wooden board into a predetermined shape (substantially U-shaped).

That is, first, after laminating a laminated veneer on a back surface of a decorative veneer of a predetermined size in a shape in which both side plates and a bottom plate are developed, except for a portion corresponding to a corner portion of a side plate and a bottom plate, the laminated plate Bend the decorative veneer at a place where it does not exist to form a substantially U-shape. On the other hand, a comb-shaped corner member having a plurality of cut grooves is prepared, resin is filled in the cut groove of the corner member, and the corner member is bent in the cut groove when the resin is uncured. To form a shape along the corner portion and fit to a portion of the decorative veneer where there is no laminated plate.
Thereafter, a space is formed between the decorative veneer and the corner member by injecting a resin from the side end face to fill the space, and then curing the resin to attach the corner member to the decorative veneer. Is.

(Operation) With the above configuration, in the present invention, the corner member that constitutes the laminated board at the corner portion of the wooden board is a comb-like member having a plurality of cut grooves, and the corner member is bent at the cut grooves. Since it is designed to be shaped along the part,
It is possible to easily perform a series of curve forming processing of the corner member. Further, since the bending angle and the radius of curvature can be freely changed, one type of corner member can be used also when changing the shape of the corner portion of the wood material.

Moreover, since the resin is filled in the kerf of the corner member and in the space between the corner member and the decorative veneer, it is possible to sufficiently secure the rigidity at the corner portion of the wood material, and to insulate the heat. It is possible to maintain good quality and wood texture.

(Example) Hereinafter, the Example of this invention is described based on drawing.

The present invention will be described in detail in the section "Prior Art" in FIGS.
As described with reference to the drawings, a wooden bathtub in which side plates 2 and 2 and a bottom plate 3 facing each other are continuously formed by a single wooden board 1 obtained by attaching a decorative veneer 7 to a laminated board 6. The method of manufacturing the wooden bathtub will be described with reference to FIG.

When molding the wood board 1 into a predetermined shape (substantially U-shaped),
First, as shown in FIG. 1 (a), a decorative veneer 7 made of a cypress or the like having a predetermined size and having both side plates 2 and 2 and a bottom plate 3 of a bathtub developed is prepared. On the back surface of the bathtub, the parts corresponding to the side plates 2, 2 and the bottom plate 3 of the bathtub (that is, the parts excluding the corners) are laminated plates 6a, such as plywood and LVL, respectively.
6a and 6a are bonded using a water resistant adhesive (adhesive such as epoxy-based or water-based polymer / isocyanate-based adhesive). Thereafter, the decorative veneer 7 to which the laminated plates 6a, 6a, 6a are adhered is put together with a male mold 11 corresponding to the inner surface shape of the bathtub prepared in advance as shown in FIG. The decorative plate 7 is bent at a place where there is no laminated plate 6a corresponding to the corner between the side plate 2 and the bottom plate 3 and is formed into a substantially U shape.

On the other hand, as shown in FIG. 4 (b), a laminated plate 6d having a predetermined size for the corner member is prepared, and a large number of cut grooves 9, 9, Are formed in a comb shape at substantially equal intervals. The thickness of the corner member laminated plate 6d is the same as that of the side plate 2 and the bottom plate 3 of the bathtub.
It is set smaller than the thickness of 6a. After that, each cut groove 9 of the laminated plate 6d is filled with a resin 10 such as epoxy resin, and when the resin 10 is uncured, the laminated plate 6d is bent at the cut grooves 9, 9 ,. A corner member 6b curved to have a predetermined bending angle and curvature along the corner portion is formed by (see FIG. 4 (c)), and the corner members 6b and 6b are formed on the decorative veneer 7 where there is no laminated plate 6a. Fit (curved part).

In the case of bending the corner member 6b as described above, a normal flat plate-shaped laminated plate 6d is used, and the kerf 9 formed in the laminated plate 6d.
Corner member by simple processing such as bending at 9, ...
6b can be easily molded, and its workability can be improved. Further, since the bending and the radius of curvature of the corner member 6b can be freely changed, one kind of corner member can be used when changing the shape of the corner portion of the wood material 1.
6b or the corner member laminated plate 6d can also be used. As a result, it becomes possible to easily manage the parts and contribute to cost reduction and the like.

Then, each corner member 6b is attached to the decorative veneer 7 by injecting and filling the resin 10 from the side end faces of these spaces into the space formed between the decorative veneer 7 and each corner member 6b, and curing the resin. Then, after covering the entire back surface of the decorative veneer 7 with the laminated plate 6 to integrate them, the wooden plate 1 including the integrated decorative veneer 7 and the laminated plate 6 is released from the male mold 11. . After that, the two side plates 5 and 5 of the wooden board 4 in the remaining bathtub are attached to the wooden board 1 and attached members such as a frame member 8 are attached at predetermined positions. By the above, the wooden bathtub as shown in FIGS. 2 and 3 is provided.

And, the side plates 2 of the thus manufactured bathtub facing each other,
As shown in detail in FIG. 4, the corner portion of the wooden board 1 that continuously forms 2 and the bottom plate 3 has kerfs 9, 9 ,. Although formed, since the resin 10 is filled in each of the kerfs 9 and in the space between the corner member 6b and the decorative veneer 7, it is the same as or similar to the case where the conventional corner member has no kerf. Since it has sufficient strength as described above, durability can be improved. Further, the heat resistance at the corner can be maintained well, and the decorative veneer 7 forming the inner surface of the bathtub at the corner is no different from the conventional one, and the wood texture can be favorably maintained.

The present invention is not limited to the above-mentioned embodiments, but includes various other modified examples. For example, in the above embodiment, when attaching the laminated plate 6 to the back surface of the decorative veneer 7, the laminated plates 6a, 6a, 6a are adhered only to the portions corresponding to the side plates 2, 2 and the bottom plate 3 of the bathtub, The laminated plate was not adhered to the portion corresponding to the corner portion between the side plate 2 and the bottom plate 3 of the bathtub, but the entire back surface of the decorative veneer 7 was adhered with one laminated plate, and then from the laminated plate. You may make it cut and remove the part corresponding to the corner part of the bathtub.

When the decorative veneer 7 and the laminated plate 6 are attached, both
When the waterproof sheet is interposed between the seven and the six, the effect that the water absorption of the laminated plate 6 can be prevented more reliably is obtained.

(Effects of the Invention) As described above, according to the method for manufacturing a wooden bathtub of the present invention, the corner portion of the wooden board formed of the laminated plate and the decorative veneer and continuously forming the side plate and the bottom plate facing each other is formed. The corner member that constitutes the laminated plate is formed by bending a comb-like member having a plurality of cut grooves at the cut grooves, and therefore the molding can be easily performed and the bending angle and the radius of curvature can be appropriately changed. It is possible to improve workability and easiness of parts management. Moreover, since the resin is filled in the space between the kerf of the corner member and between the veneer and the decorative veneer, it is possible to ensure good strength, heat insulation and wood texture at the corners of the wood board. It is possible and very advantageous for practical application.
