Abstract

(57) [Summary] [Purpose] The purpose is to prevent warpage that occurs due to water absorption, which is a drawback of wood, and contraction and expansion resulting from it, that is, to stabilize dimensional stability. [Structure] The sum of the vertical cross-sectional area of the plywood or laminated wood 2 and the vertical cross-sectional area of the plywood or laminated wood 2 is at least at the lower or central portion of the back surface of the substrate 1 in which the board 3 is pasted on the surface of the plywood or laminated wood 2. A warp-reinforcing rod 4 having a vertical cross-sectional area is mounted in the longitudinal direction so that the warp does not become noticeable. [Effect] It is easy to attach a thin veneer to the surface, and there is little warpage, making it easy to attach as a product.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a long press component base material, and more particularly to a long press component base material that can be easily attached to a surface of a thin veneer and has a small amount of warp so that it can be easily attached as a product.

[0002]

[Prior art]

 In recent years, useful resources that can actually be used for timber have been depleted with the strengthening of environmental protection, and Lauan plywood and laminated timber, which have been representative of cheap timber resources, are no longer able to produce good surface veneers. is there. For this reason, even with long presses that are decoratively attached to the wall surface, it is very difficult to overlay the laminated thin veneer on the surface of the plywood or laminated wood, and surface treatment with putty material is an urgent task.

[0003]

[Problems to be solved by the device]

 Therefore, one method is to put a board on the entire surface of the plywood or laminated wood, but if the board is stuck on the surface of this plywood or laminated wood, the balance of the plywood or the laminated wood becomes unbalanced and One of the drawbacks was water absorption and the resulting shrinkage and expansion, which inevitably caused warpage.

[0004]

[Means for Solving the Problems]

 The present invention is to provide a long-pressing base material for the purpose of preventing warpage caused by water absorption, which is the biggest drawback of wood, and shrinkage and expansion resulting from it, that is, dimension stabilization.

The gist of the present invention is that the sum of the vertical cross-sectional areas of the plywood or laminated wood is the sum of the vertical cross-sectional area of the board at the lower or central part of the back surface of the substrate where the board is pasted on the surface of the plywood or laminated wood made of lauan This is a long-pressing base material in which a reinforcing rod for preventing warpage of a vertical cross-sectional area is attached in the lengthwise direction so that at least a length warp with respect to the vertical cross-sectional area is not significant. Next, the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[0006]

【Example】

 First, when a board is pasted on the surface of plywood or laminated wood, the warpage becomes remarkable unless the thickness of the plywood or laminated wood is more than 5 times the thickness of the board. For example, as shown in FIG. 1, conventionally, unless the thickness of the plywood or the laminated member 2a is 5 times or more the thickness of the board 3a that constitutes the substrate 1a, it is possible to use the long press with the decorative thin veneer 5a attached to the surface of the substrate 1a. The warp is very noticeable.

The long-pressing base material of the present invention will be explained with reference to FIGS. 2 to 6. First, 1 is a plywood made of softwood or lauan wood or a substrate having a board 3 attached to the surface of a laminated wood 2. Therefore, the sum of the vertical cross-sectional area of the board 1 at the lower part of the back surface (FIGS. 3, 6) or the central portion (FIGS. 2, 4 and 5) of the plywood or laminated wood 2 is relative to the vertical cross-sectional area of the board 3. A reinforcing rod 4 for preventing warpage of a longitudinal section is attached in the longitudinal direction so as to have a magnification (5 times or more) such that at least the length warp is not remarkable. Note that 5 is a thin veneer plate and 6 is a kamoi.

Next, when the long-pressed substrate 1 is a plywood or laminated wood 2 having a board 3 of about 3 m / m on the front surface and a back surface of about 5 to 9 m / m, unfortunately, the thickness ratio is 1: 3. There is up to, and there is one-sided warpage. Therefore, wood (reinforcing rod 4) is attached to the back surface of the substrate 1 to eliminate this balance, but if the height of the long press is 90 to 120 m / m, the vertical cross-sectional area is 5 × 90 to 9 × 120 (mm ² The timber (reinforcing rod 4) corresponding to about 2/3 of that) is required. Therefore, considering a material thickness of 12 to 35 m / m, it is necessary to stick a material (reinforcing rod 4) of about 12 × 25 to 35 × 21 m / m. The reinforcing rod 4 is made of the same or similar material as the plywood or the laminated wood 2, but if a material that is hard to cause lateral warp is selected, the warp prevention effect may be obtained even with a cross sectional area of 5 times or less. When the reinforcing rod 4 is attached to the lower part of the back surface of the substrate 1, the reinforcing rod 4 is fixed to the upper surface of the kamoi 6 and the long press is attached as shown in FIG. When it is attached to the wall 7, the long push is attached to the wall 7 by an easy fitting method in which the reinforcing rod 4 is fitted as a guide into the fitting hole 8 provided in the wall 7 above the kamoi 6 as shown in FIG. It is something.

Even in the case of long-pressing to be attached to the wall 7, there is a risk of peeling before the initial adhesive force becomes strong due to the large warp stress, so it is provided as a straight long-pressing material with no warp as much as possible. There is a need to.

[0010]

[Effect of device]

 Since the long-pressing base material of the present invention is configured as described above, it is economical to attach a thin cosmetic veneer to the surface without the need for groundwork repair work. In addition, it is possible to prevent the warpage caused by the water absorption of the wood and the contraction and expansion resulting therefrom, that is, the dimension stability can be achieved.
