Abstract

(57) [Summary] [PROBLEMS] When the water absorption of the single veneer constituting the core material differs between the front veneer and the rear veneer, the whole door warps when the veneer absorbs the moisture of the adhesive. It will cause deterioration in quality, wood will be chipped and solidified with adhesive,
Processing into a panel requires a huge amount of equipment and a hot water source. SOLUTION: The frame structure 1 is composed of a combination of a core material 2 on both sides and a core material 3 connecting the core materials 2 on both sides vertically and intermediately, wherein the core materials 2 and 3 are from the front side of the door to the back side. A plurality of veneers 4 are joined to each other with an adhesive at a wide surface 5 so that even if the decorative material 6 is adhered to the front and back surfaces of the framework structure 1 as described above. Since the same veneer 4 has an exposed end face on the front and back sides of the core members 2 and 3, the water absorption rate is the same, the warp hardly occurs, and the quality of the entire door is deteriorated over a long period of time. And no special equipment or hot water source is required for production.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a frame structure used for a door of a closet, for example.

[0002]

[Prior art]

 Conventionally, as a frame structure of a door such as a closet, a hollow panel shape shown in FIGS. 4 and 5 is used.

[0003] The frame structure 10 is composed of a combination of a plurality of core materials 11, each of which is wide in the width direction of the door and is a thin single plate (for example, Rawan having a thickness of 0.8 to 1.0 mm). (Made of a material) from the front side to the back side, and are formed by applying heat and pressure using an adhesive.

Then, the core members 11 configured as described above are arranged vertically and horizontally, and the core members 11 are temporarily fixed 13 to form a hollow panel, and a decorative material 14 is adhered to the surface thereof with an adhesive to open the door. Finish.

In this door frame structure 10, when the water absorption of the front plate and the back plate of the veneers 12 constituting each core material 11 are different, the veneers 12 When water is absorbed, as shown by the imaginary line in FIG. 5, a warp 15 is generated in the entire door, and quality is deteriorated.

[0006] Thus, although not shown, a core material formed by forming wood into chips and solidifying the same with an adhesive to form a hollow panel shape has been developed. it can.

[0007]

[Problems to be solved by the invention]

 However, there are problems such as the need for extensive equipment and a hot water source to process wood into chips, solidify it with an adhesive, and process it into a hollow panel shape.

Accordingly, an object of the present invention is to provide a door frame structure that can solve the above-described problems.

[0009]

[Means for Solving the Problems]

 The means for solving the problem in the present invention is that each core material of the door frame structure composed of a combination of a plurality of core materials is formed by connecting a plurality of thick veneers from the front side to the back side. It is joined by a thick surface.

[0010] In the above configuration, the end surfaces of the same veneer are exposed on the front side and the back side of the core material, so that the water absorption is the same. Therefore, for example, a cosmetic material is applied by applying an adhesive to both surfaces of the veneer. Even if it is adhered, warping of the veneer hardly occurs, and it is possible to prevent deterioration in quality over a long period of time.

[0011]

[Embodiment of the invention]

 Hereinafter, the door frame structure according to the embodiment of the present invention will be described with reference to FIGS.

The frame structure 1 according to the embodiment of the present invention is used for a large door such as a closet, for example, and connects the left and right cores 2 to each other at the top and bottom and at the middle. It is composed of a combination of core materials 3.

Each of the core members 2 and 3 is formed by joining a plurality of thick veneers 4 from the front surface side to the rear surface side of the door with an adhesive at the wide surface 5. The decorative material 6 is adhered to the front and back surfaces of such a frame structure 1.

Next, a method of assembling the framework structure 1 will be described. As shown in FIG. 3, for example, a thin plate (for example, a lauan material is used) serving as a veneer 4 is bonded to an adhesive (for example, a urea resin or the like). Phenol resin-based resin is used), and the mixture is pressurized at 5 to 10 kg / cm ² at a temperature of 110 ° ± 10 ° C. for 10 to 20 minutes and then cooled.

[0015] The thus obtained product is cut into a predetermined width as shown by a dashed line in FIG. The core members 2 and 3 are oriented so as to be thicker from the front side to the back side, and another core member 2 and 3 are spread over the veneers 4 at the ends of the core members 2 and 3 on both sides. It is temporarily fixed to form the framework structure 1. Then, an adhesive is applied to both sides of each of the core members 2 and 3 and the decorative material 6 is attached to complete the door.

At this time, the end faces of the same veneer 4 are exposed on the front side and the back side of the core members 2, 3, so that the water absorption is the same. Therefore, even if an adhesive is applied to both surfaces of the veneer 4 and the decorative material 6 is adhered, warping of the veneer 4 hardly occurs. For this reason, it is possible to prevent quality deterioration over a long period of time.

As described above, according to the embodiment of the present invention, the end faces of the same veneer 4 are exposed on the front side and the back side of the core members 2, 3. Even if the decorative material 6 is adhered by applying an adhesive to the door, the warp hardly occurs, and it is possible to prevent the deterioration of the quality of the entire door for a long period of time.

In addition, it is possible to provide the framework structure 1 serving as a high-quality door without requiring special equipment or a hot water source.

[0019]

[Effect of the invention]

 As is clear from the above description, in the present invention, each core of the door framed structure composed of a combination of a plurality of cores is composed of a plurality of veneers each having a large thickness from the front side to the back side. Since the end faces of the same veneer are exposed on the front side and the back side of the core material, the water absorption rate is the same, and thus, for example, as in the embodiment, Even if an adhesive is applied to both sides of the veneer and the decorative material is adhered, warping of the veneer hardly occurs, and it is possible to prevent deterioration in quality over a long period of time.
