Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a wooden building material, and is, for example, a composite material obtained by disassembling a plurality of kamoi materials used in Japanese-style construction.

[0002]

[Prior art]

 In Japanese-style architecture, a sill and a Kamoi that slide doors, sliding doors, and other fittings are indispensable, but these are so-called infinitely long timbers with multiple grooves such as two-row or three-row formed in the longitudinal direction. Used.

[0003] Therefore, it takes time and labor for carpenters to form a groove in solid wood or finish a surface with a plane. Moreover, the use of high-quality wood such as Japanese cypress has to be expensive because the cost of the material is high in addition to the time and effort of the carpenter.

Therefore, in order to reduce the cost of wooden construction materials, so-called laminated materials may be used in addition to the load bearing structural materials. This laminated lumber is used to create a wooden construction material of desired length and width by bonding so-called thinned timber etc. with an adhesive or the like.

By the way, aside from the sill, Kamoi is a wooden building material for sliding guides of fittings, so that it is not necessary to be a load bearing structural material because a large force is not applied. It can be said that laminated wood is sufficient.

[0006]

[Problems to be solved by the device]

 In general, wooden building materials are expensive, using solid wood, except for decorative panels for indoor use. If they are not load bearing materials, laminated timber can be used to significantly reduce costs. In addition, solid wood often has knots, which often impair aesthetics, and the use of knotless wood is increasingly expensive.

In view of the above circumstances, the present invention has been made with the object of providing an inexpensive wooden building material such as a Kamoi based on laminated wood.

[0008]

[Means for Solving the Problems]

 The wooden building material according to the present invention has engaging projections formed on both left and right sides, and a base member having a rectangular cross section with a predetermined length and an engaging groove formed on one side of the central part and the engaging projections. A pair of right and left side members each having a rectangular cross section with a predetermined length and symmetrically formed engaging grooves to be fitted, and a rectangular cross section with a predetermined length and having an engaging projection to be fitted into the engaging groove of the base material. The side members are joined to the engaging projections and the engaging grooves on both the left and right sides of the base material with an adhesive, and the engaging projections of the middle material are attached to the engaging groove at the center. It is characterized in that the joiner is joined through and the fitting sliding grooves are formed on the left and right sides of the middle material.

[0009]

[Action]

 If the engaging groove of the side material is fitted into the engaging protrusion of the base material with an adhesive and the engaging protrusion of the middle material is fitted into the engaging groove of the base material with an adhesive, the Building materials are formed. Therefore, the cost can be reduced and the appearance can be improved by making the laminated material in which the base material, the side material and the middle material are covered with the decorative plate.

[0010]

【Example】

 An embodiment of this invention will be described below with reference to the drawings. As shown in FIG. 1, a wooden building material 1 such as a Kamoi comprises a base material 2, a pair of side members 3, 3 and a middle material 4, which are engaged protrusions and which are fitted with an adhesive or the like. It is synthesized by being integrally joined by the engaging groove to be attached.

The base material 2 is a laminated member having a rectangular cross section having a predetermined length and width, one or a plurality of engaging grooves 2a are formed in the central portion of the width, and one or a plurality of engaging grooves 2a are provided on the left and right sides of the width, respectively. The engaging projections 2b, 2b are provided so as to project in the longitudinal direction.

As shown in FIG. 2, the engaging groove 2a includes two laminated blocks 5 and 6 which are attached to each other at the central portion of the width of the base material 2 which is an laminated member, and the engaging protrusions 2b include left and right sides. The assembled blocks 7 and 8 located at are formed by cutting in the longitudinal direction with a woodworking machine or the like.

On the width surface of the base material 2, a decorative plate 9 having a good-looking grain or the like is attached on one surface. This decorative plate 9 is formed by bonding thin plates to the width surface with an adhesive at the stage of producing laminated wood.

The side members 3 are made of laminated wood whose three faces are covered with a decorative plate 9 similar to the base material 2. The side materials 3 are a pair of laminated wood having the same length as the base material 2 and a rectangular cross section. The engaging groove 3a is formed by a woodworking machine or the like.

The engagement groove 3a is formed by cutting one laminated block 10 to which the side member 3 which is a laminated member is adhered in the longitudinal direction by a woodworking machine or the like. The engaging groove 3a engages with the engaging protrusion 2b of the base material 2, and the depth of the engaging groove 3a and the height of the engaging protrusion 2b are the same.

The middle member 4 is also made of laminated wood having a rectangular cross section whose three surfaces are covered with a decorative plate 9. The middle member 4 has the same length as the base member 2 and the side members 3, and has an engaging projection of a predetermined height at the center of the short side. 4a is formed. The engaging protrusion 4a engages with the engaging groove 2a of the base material 2, and the height of the engaging protrusion 4a and the depth of the engaging groove 2a are the same.

Therefore, as shown in FIG. 2, an adhesive is applied to the engaging protrusions 2b on both the left and right sides of the base material 2 and the engaging grooves 3a of the side member 3 to be bonded to each other, while the engaging protrusions of the middle member 4 are adhered. By applying 4a to the engaging groove 2a of the base material 2 and applying the same to each other, a dam having two symmetrically arranged fittings sliding grooves 11, 11 is created.

[0018] The kamoi thus created has the same quality as the veneer 9 made of the same material and has no knots. It looks as if it was made from beautiful solid wood such as grain, and it is provided at a low price. This reduces the cost of wooden construction.

In addition, in the above-mentioned embodiment, only one line of the intermediate member 4 is formed, but when there are three or more fitting sliding grooves, a plurality of them are used. Further, the base material 2, the side material 3 and the middle material 4 are synthesized by the laminated wood, but it goes without saying that they may be formed by solid wood such as thinned wood.

[0020]

[Effect of device]

 According to the present invention described above, for example, a duck material is divided into four parts, and these four parts are joined to the engaging projections and the engaging grooves with an adhesive. It can be made at a very low cost as compared with the labor and cost of making a lumber.

Moreover, by using the laminated wood covered with a decorative veneer having a good appearance, it is possible to easily obtain a long wooden construction material without knots and to provide it at a low cost.
