Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pressure-resistant composite flooring material that can be sufficiently applied as a wooden floor for footwear.

[Prior art] Generally, when a wooden floor is used for walking on foot,
A sharp pointed object, such as a thin high heel heel or an umbrella butt, may be damaged by being locally dented or opened by a hole.

In order to prevent such a situation from occurring, for example, means such as injecting and hardening a synthetic resin into the wooden flooring material or coating the surface with a hard material can be considered. New problems such as loss and surface slippage occur.

[Problems to be Solved by the Invention] The present invention has been made to solve the conventional problems as described above, and can be easily applied to a locally concentrated load without losing the unique treading feeling unique to wood. It is a technical task to provide a wooden flooring material that is not damaged.

[Means for Solving the Problems] As a means for solving such problems, the present invention is to adhere a load-bearing backing material such as phenolic resin-impregnated paper to the back surface of a veneer veneer, and to attach it to the floor. The gist of the invention is that the material is press-bonded to the surface of a base plate as a base of the material.

[Operation] Since a load-bearing backing material is adhered to the back of the veneer veneer, the pressure resistance is remarkably improved, and the surface of the veneer veneer can be utilized as it is to maintain the unique treading feeling of wood.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of the present invention, wherein 1 is a base plate serving as a base of a flooring material, which is made of a wood material such as plywood or muk wood, laminated wood, and has a thickness of 2.4 to 20 mm. Is formed. Reference numeral 2 denotes a decorative veneer for flooring, the thickness of which is 0.2 to
1.5 mm, the load-bearing backing material 3 is stuck on the back side. In this case, the load-bearing backing material 3 is a phenolic resin-impregnated paper having a thickness of 0.5 to 1.5 mm. However, the present invention is not limited to this, and another appropriate material may be used.

Conventionally, there is a veneer in which glass fiber or Japanese paper is adhered as a backing material to the back side of the veneer veneer, but this is for preventing the veneer veneer from cracking and for improving the pressure resistance. is not.

The decorative veneer 2 to which the load-bearing backing material 3 is attached as described above is pressure-bonded to the base plate 1 to form a flooring according to the present invention.

The floor panel thus formed has a remarkably improved withstand pressure against local impacts.
Although a hole was easily opened at a pressure of / φ8 or less and restoration was impossible, even a very small dent of 0.3 mm or less occurred at 80 kg / φ8 in this flooring.

FIG. 2 shows a second embodiment of the present invention, in which a base plate 1, a decorative veneer 2 and a load-bearing backing material 3 adhered to the back surface of the veneer veneer in the same manner as described above. Although it has the same points, it differs from the first embodiment in that the cushioning material 4 is inserted when it is pressed against the base plate 1. In this case, the cushion material 4 may be a rubber sheet having a thickness of about 0.5 to 10 mm, a rubber foam material, an ethylene foam material, or the like.

FIG. 3 shows a third embodiment of the present invention. A cushion material 5 having a thickness of 1 to 5 mm is further provided on the back surface of the floor plate of the first embodiment or the second embodiment, that is, on the back surface of the base plate 1. It is attached.

In the second and third embodiments, the cushion material is interposed, so that the impact during walking can be reduced and the stepping comfort can be further improved.

[Effects of the Invention] As described above, according to the present invention, since the load-bearing backing material is attached to the back surface of the veneer veneer, the withstand pressure against a localized concentrated load can be significantly increased. Even if a shock is applied with the heel of a high heel or a pointed object, the hole does not easily open or dent,
Since it can be sufficiently applied as a floor material for an earth foot, and a surface veneer veneer can be used as it is, excellent effects such as maintaining a good treading feeling as wood can be obtained.
