Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to precious wood sheets that are used mainly as interior flooring materials among building materials.Background ArtIn recent years, wood materials have been increasingly used as interior flooring materials. Flooring made of natural wood veneer attached to a plywood base is often used.

Problems to be Solved by the Invention However, although the above-mentioned flooring materials are suitable for construction on large joist bases, they lack water resistance and are subject to large dimensional changes due to moisture when directly applied to concrete slabs, panel panels, etc. In addition, the base material is always uneven and does not blend well with the base material, and after installation, it tends to sag or float at the joint part.In addition, natural precious wood veneers have the same physical properties as wood base materials. Therefore, there is no problem with bonding, but since the physical performance is completely different to base materials other than wood, such as synthetic resin, there are various problems in bonding, and none have been commercialized. .

In order to solve these problems, the present invention is a sheet made of a synthetic resin sheet as a base material, a natural wood veneer is pasted on the top surface, and a base fabric is pasted on the bottom surface as a backing material. Can be directly attached to the base of slabs, panel panels, etc., has excellent dimensional stability, and does not crack or peel.
The purpose is to provide beautiful and precious wood shitra.

A foolproof way to solve problems Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

1 This is a precious wood sheet 4a in which a natural precious wood veneer 2a is attached to the front surface of a synthetic resin sheet 1, and a base fabric 3 is attached to the back surface.

2 A precious wood sheet 4b is obtained by pasting a natural precious wood veneer 2b with a thickness of 1/3 or less of the thickness of the synthetic resin sheet 1 on the front surface of the synthetic resin sheet 1, and pasting a base fabric 3 on the back surface. .

Note that in the precious wood sheets 4a and 4b, an embodiment may be considered in which a natural fiber such as hemp or a synthetic fiber such as vinylon is used as the material for the base fabric 3.

Functions and Effects Precious wood sheets 4a and 4b of the eleventh and second embodiments of the present invention
are natural wood veneers 2a, 2 on the surface of the synthetic resin sheet 1.
b is attached, it is highly water resistant and flexible, so it blends well with the base material, and there is no lifting at the joint, and it can be applied directly to the base material such as concrete slabs and panel panels. It is possible to wear it. Natural wood veneer and synthetic resin sheet have physically contradictory properties (veneer shrinks when exposed to heat, while resin sheet expands, and veneer expands when exposed to moisture). On the other hand, the resin sheet shrinks), but the mutual elasticity is canceled out and the precious wood sheet)4
The dimensional stability of a and 4b is dramatically improved.

In the precious wood sheet 4b of the second embodiment, the dimensional stability is best when the thickness of the natural precious wood veneer 2b is limited to 1/3 or less of the thickness of the synthetic resin sheet. For example, the synthetic resin sheet When the thickness of the natural wood veneer 2b is 1.5 to 3.0 mm, the thickness of the natural wood veneer 2b is 0.3 to 1.0 mm. Examples of adhesives used include evaporated ethylene complex vinyl, vinyl urethane, and urethane adhesives. However, by pasting the base fabric 3 on the back side of the synthetic resin sheet 1, the dimensional stability of the precious wood sheet and its adhesion to the base material are improved, and it can be easily peeled off when replacing the sheet. As the material of the base fabric 3, linen, vinylon, etc., as in the embodiment example, are excellent materials, and the above-mentioned remarkable effects can be achieved.
