Description

  The present invention relates to a panel for joinery used for a door material or a partition material.

As this type of joinery panel, there is one having a core frame structure shown in FIG.
FIG. 4 is an overall perspective view showing an example of the structure of a core frame body in a conventional joinery panel.
In the figure, 100 is a core frame of a panel for joinery, 101 is a vertical frame member, 101a is a horizontal core member, 102 is a horizontal frame member, and 102a is a vertical core member. As the core frame 100, LVL, particle board (PB), or the like is used, and the horizontal core material 101a and the vertical core material 102a are fitted in a frame constituted by the vertical frame material 101 and the horizontal frame material 102. Since these are formed of a plurality of discrete pieces, the assembly and the management of the pieces are time-consuming and tend to be costly. Moreover, since the surface material comprised by the plate body and decorative sheet which consist of medium fiber boards (MDF) etc. is affixed on the surface of the core frame 100, the adhesiveness of the core frame 100 and a surface material is attached. In order to improve the accuracy, the dimensional accuracy of the core frame 100 is required. However, it has not been easy to increase the dimensional accuracy of the core frame 100 composed of a plurality of pieces as shown in FIG. Therefore, in addition to requiring the number of manufacturing steps for assembling the core frame 100, it is difficult to improve the production speed because dimensional accuracy is required.
Furthermore, in the structure of the core frame 100 as shown in FIG. 4, since a plurality of hollow portions 103 are formed, if the surface is struck after the surface material is applied, the struck sound becomes a hollow sound. There was also a problem of being damaged.

In Patent Document 1 below, a reinforcing plate for preventing warping of the frame material is constituted between a core material in which a vertical frame material (a cocoon material) is formed by juxtaposing a plurality of laminated materials and a frame material made of solid lumber. Has been disclosed.
According to this, even if it tries to repeatedly deform the expansion and contraction of the frame material, it is suppressed by the reinforcing plate, so that it is possible to prevent warping and cracking of the solid lumber.

However, in the case where the same plate material is simply overlapped and bonded as in Patent Document 1, a cavity is not formed as in the conventional example of FIG. 4, but there is a problem that the weight is increased. If the panel for joinery is heavy, it is difficult to carry, and when it is used as a door material, it is difficult to install and must be firmly attached. On the other hand, in order to reduce the weight, when a light material is used as a plate material, a new problem that strength is weakened occurs.
In recent years, the use of materials suitable for protecting the natural environment, such as Falkata, has been demanded for the development of products compatible with the global environment for wooden materials used as building materials such as panels for joinery. A product is sought.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide a joinery panel that is light in weight, inexpensive and easy to manufacture while maintaining practical strength. is there.

In order to achieve the above object, the joinery panel of the present invention has a surface material attached to the surface of a core frame body composed of a vertical frame material and a horizontal frame material. It is composed of a laminated material laminated in the direction, and the specific gravity of the plate material forming the outer layer of the laminated material is 0.60 to 0.75, and the specific gravity of the plate material forming the inner layer is 0.35 to 0.00. 50, the specific gravity of the plate material forming the outer layer is larger than the specific gravity of the plate material forming the inner layer, and the outer layer is laminated on both sides of the inner layer .
In the present invention, the horizontal frame material may be LVL or the like, and the horizontal frame material may be composed of a laminated material obtained by laminating plate materials in the same manner as the vertical frame material.
Moreover, the board | plate material which makes an inner side layer can be comprised by the Falkata material, and the surface material can also be comprised by affixing the resin decorative sheet on the surface of a board | plate body.

According to the present invention, the specific gravity of the plate material forming the outer layer of the laminated material constituting the vertical frame material is 0.60 to 0.75, the specific gravity of the plate material forming the inner layer is 0.35 to 0.50, and the outer layer Since the specific gravity of the plate material in the inner layer is larger than the specific gravity of the plate material in the inner layer, it is possible to reduce the weight while maintaining the strength of the vertical frame material, and it is possible to provide a joinery panel that is easy to construct. In particular, since the specific gravity of the plate material constituting the outer layer is large and strong, when used as a door material, the holding force of the hinge screw can be increased. Further, the vertical frame member is not composed of a plurality of pieces as in the prior art, and is formed into blocks, so that the constituent members of the core frame body can be shared, and the cost of inventory management can be reduced.
Further, the structure of the core frame body is such that the vertical frame material is blocked, so that the assembly of the core frame body is simplified, the assembly time can be greatly shortened, and the production speed can be improved.
And since the vertical frame material is composed of laminated material made by laminating plate materials, a hollow part is not formed unlike the structure of the conventional vertical frame material, and a high-grade panel for joinery using solid lumber. It can be.
If the Falkata material is used as the plate material forming the inner layer, the Falkata material is lightweight and inexpensive, so that it is possible to reduce the weight and cost of the joinery panel. Falkata is a legume plant that grows very quickly and can be harvested in 5 to 7 years, so it does not cause damage to the natural environment or forests. It can be a mold product.
In addition, since the surface of the vertical frame material can be configured to be flush with the dimensional accuracy, the surface material configured by applying the resin decorative sheet to the surface of the plate material can be firmly and firmly attached.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig.1 (a) is a whole perspective view which shows an example of the structure of the core frame applied to the panel for joinery concerning this invention, FIG.1 (b) is XX arrow sectional drawing in Fig.1 (a). 2 (a) is an overall perspective view showing the joinery panel, FIG. 2 (b) is a cross-sectional view taken along line YY in FIG. 2 (a), and FIG. 3 is a core applied to the joinery panel. It is a whole perspective view which shows the modification of the structure of a frame.

First, referring to FIG. 1 and FIG. 2, a joinery panel as an example of the present invention will be described.
The panel 1 for joinery is obtained by attaching a surface material 20 to the surface of a core frame 10 composed of a vertical frame material 11 and a horizontal frame material 12, and is used as a door material, a partition material, or the like. The joinery panel in the figure shows a braided door panel suitably used as a door material.
As shown in FIG. 1A, the core frame body 10 is configured by combining a vertical frame member 11 and a horizontal frame member 12 that are each made into a block, and having a shape like a vertically long frame having a hollow portion 2 in the center. Has been. In the cavity 2 formed in the center of the core frame body 10, a mirror plate or a glass plate is fitted later.
The vertical frame member 11 and the horizontal frame member 12 are made of a laminated material obtained by laminating a vertically long rectangular parallelepiped plate material cut to a predetermined dimension in one direction, and blocked into a total of four blocks. The vertical frame member 11 and the horizontal frame member 12 are joined with an adhesive. In the illustrated example, since the core frame 10 is configured in a vertically long (rectangular) frame shape as described above, the laminated material that becomes the blocked vertical frame material 11 is arranged in a vertical direction, The laminated material used as the frame material 12 adheres the joint portion between the vertical frame material 11 and the horizontal frame material 12 in a state of being arranged in the horizontal direction. In addition, the board | plate material which comprises a laminated material can also be made into LVL.

As shown in FIG. 1B, the vertical frame member 11 is formed by stacking five plate members in the vertical direction, and the plate members are joined by an adhesive. The plate material 11a forming the outer layer, that is, the specific gravity of the plate material 11a configured on both sides is larger than the specific gravity of the plate material 11b in the inner layer. Specific gravity here refers to the air-dry specific gravity (air-dry density) measured in the air-dry state (water content 15%), and the numerical values shown below refer to the average air-dry specific gravity of each material.
For example, the outer layer 11a is made of rubber wood (specific gravity 0.64), Merck pine (Merckus pine: specific gravity 0.65), tamo (specific gravity 0.65), elm (楡: specific gravity 0.62), maple (specific gravity 0.70). ), Zelkova (specific gravity 0.62), and the like, and those having a specific gravity of about 0.60 to 0.75 are preferable. When the specific gravity of the plate member 11a forming the outer layer is smaller than 0.60, the strength (hardness) when used as the panel 1 for joinery is insufficient, and when the specific gravity is larger than 0.75, the weight tends to be increased. The handleability when used as a panel 1 for a vehicle becomes poor.
The plate material 11a forming the outer layer is not limited to the above-mentioned materials, but if rubber (rubber wood) or Merck pine is used, it is possible to configure an inexpensive material in consideration of the global environment. Moreover, since these are good in workability, dimensional accuracy can be increased.
Next, as the plate member 11b forming the inner layer, one having a specific gravity smaller than that of the plate member 11a forming the outer layer is used.
For example, the plate material 11b forming the inner layer is made of Falkata (specific gravity 0.40 to 0.48), rice tsubo (specific gravity 0.46), Japanese cypress (specific gravity 0.41), cedar (specific gravity 0.38), etc. It is preferable that the specific gravity is approximately 0.35 to 0.50. When the specific gravity of the plate 11b constituting the inner layer is smaller than 0.35, the strength (hardness) when used as the panel 1 for joinery is insufficient, and when the specific gravity is larger than 0.50, the weight tends to increase. The handleability when used as a panel 1 for a vehicle becomes poor.
The plate material 11b forming the inner layer is not limited to the above-described material, but if a Falkata material is used, it is light and inexpensive, so that the weight and cost of the joinery panel 1 can be reduced. Falkata is a legume plant that grows very quickly and can be harvested in 5 to 7 years, so it does not cause damage to the natural environment or forests. It can be a mold product.

The horizontal frame member 12 shown in FIG. 1 (a) has a structure similar to that of the vertical frame member 11 and is arranged in the horizontal direction. As shown here, the upper horizontal frame member 12 is composed of a laminated material in which five plate members are laminated to form a block, and the plate members are joined by an adhesive. The lower horizontal frame member 12 is made of a laminated material obtained by stacking six plate members, and the plate members are joined by an adhesive in the same manner as the upper horizontal frame member 12.
The plate member 12a forming the outer layer and the plate member 12b forming the inner layer are the same as the example of the vertical frame member 11, and thus the description thereof is omitted. According to this, since the upper horizontal frame member 12 has the same number of plate members as the laminated material as the vertical frame member 11, the vertical frame member can be simply cut to a predetermined length after forming the laminated member. 11 and the lateral frame member 12 can be produced. The relationship between the specific gravity of the plate members 12a and 12b forming the laminated material is the same as that of the vertical frame member 11.

FIG. 2A is a perspective view of the joinery panel 1, and a surface material 20 is attached to the surface of the core frame body 10 including the vertical frame material 11 and the horizontal frame material 12. As shown in FIG. 2B, the surface material 20 is configured by attaching a resin decorative sheet 22 to the surface of the plate body 21. As the plate body 21, a wood-based material such as plywood, LVL, particle board (PB) is used. The plate material 21 has a V-groove 21a formed in advance in a portion that comes into contact with the corner portion of the core frame body 10 so as to be attached along the corner portion 11c of the core frame body 10.
As the resin decorative sheet 22, a vinyl chloride sheet, a polypropylene resin sheet or the like is used, and the design of the panel 1 for joinery is enhanced by printing a wood grain pattern or the like on the surface thereof.
And when using the panel 1 for joinery formed in this way as a door material, the cutting process for attaching a door knob or a hinge screw will be made in a later process.

According to the above, since the specific gravity of the plate material 11a in the outer layer of the laminated material constituting the vertical frame material 11 is larger than the specific gravity of the plate material 11b in the inner layer, the weight of the vertical frame material 11 is maintained while maintaining the strength. Therefore, the joinery panel 1 can be easily constructed. In particular, since the specific gravity of the plate material 11a forming the outer layer is large and strong, the holding force of the hinge screw attached when used as a door material can be increased. Further, the vertical frame member 11 is not composed of a plurality of pieces as in the prior art, but is formed into blocks, so that the constituent members of the core frame body 10 can be shared, and the cost of inventory management can be reduced. it can. If the horizontal frame member 12 has the same structure as that of the vertical frame member 11 as shown in the figure, the constituent members of the core frame body 10 can be further shared.
Furthermore, since the structure of the core frame 10 is such that the vertical frame material 11 and the horizontal frame material 12 are blocked, the assembly of the core frame 10 is simplified, the assembly time can be greatly reduced, and the production speed is improved. be able to.
Since the vertical frame member 11 and the horizontal frame member 12 are made of a laminated material obtained by laminating plate materials, a hollow portion is not formed unlike the structure of a conventional vertical frame member, and a high-grade such as using solid lumber. It can be set as the panel 1 for fittings with a feeling.
In addition, since the surfaces of the vertical frame member 11 and the horizontal frame member 12 can be configured to be flush with each other with dimensional accuracy, the surface member 20 can be firmly and firmly attached.

Next, a modification of the core frame structure of the joinery panel 1 will be described with reference to FIG. Here, portions common to the above-described example are denoted by common reference numerals, and description thereof is omitted.
In the example shown in FIG. 3, the structure of the vertical frame member 11 is the same as the above example, but the structure of the horizontal frame member 12 is different from the above example. Two plate members 12c are arranged on the upper side and two sheets on the lower side to constitute the horizontal frame member 12. The plate material used here can be LVL or the like, and is not particularly limited, but if the same material and the same specific gravity as those used for the plate material 11a of the outer layer are used, the door material is used. It can have strength.

Also by the above, since the specific gravity of the board | plate material 11a in the outer layer of the laminated material which comprises the vertical frame material 11 is made larger than the specific gravity of the board | plate material 11b in an inner layer similarly to the above-mentioned example, the intensity | strength of the vertical frame material 11 It is possible to reduce the weight while maintaining the structure, and it is possible to provide a joinery panel 1 that is easy to construct. Further, since the structure of the core frame body 10 is simple, the assembly of the core frame body 10 is simplified, the assembly time can be greatly shortened, and the production speed can be improved.
As in the above example, a Falkata material can be used as the plate material 11b forming the inner layer.

In addition, the shape of the panel 1 for joinery is not limited to the thing of a figure example, For example, it can also be set as the flash panel comprised by affixing a surface material on the front and back whole surface of a core frame. In this case, it is preferable to insert a lightweight honeycomb or a resin foam panel into the hollow portion formed at the center of the core frame to reinforce.
Also, the structure of the horizontal frame member 12 shown in FIG.
