Abstract

PROBLEM TO BE SOLVED: To prevent the contamination of a decorative surface by the rust of a nail fixing a floor material onto a floor joist by interposing a sheet-shaped article having airtightness between the board of the floor material and the sliced-veneer decorative board of a surface. SOLUTION: The woody floor material is constituted in such a manner that a male tongue 4 and a female tongue 5 are formed to the end face of a woody board 2 such as plywood, a particle board, an MDF, etc., in thickness of approximately 5-12 mm and a sliced veneer 1 in thickness of approximately 0.2-1.0 mm is stuck onto a top face through a sheet-shaped article 3 in thickness of approximately 0.01-0.02 mm. The woody board 2 may also be configured by laminating the MDF on plywood through the sheet-shaped article 3. A synthetic resin sheet such as polyethylene, polypropylene, etc., having high airtightness is used as the sheet-shaped article 3. The woody floor material is fixed by driving a nail 6 into a floor joist from the male tongue 4, but rust is generated in the nail 6 when the time passes for a prolonged term, and the iron of rust reacts with the lignin of the sliced veneer 1 and a decorative surface is contaminated when the iron of rust is propagated to the surface of the floor material. Accordingly, the contamination is prevented by the sheet-shaped article 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of alkali contamination of a decorative surface of a wooden flooring material.

[0002]

2. Description of the Related Art A wooden flooring material to be installed in a house is obtained by sticking a veneer to a surface of a wooden substrate such as plywood and processing a joining fruit on a peripheral edge thereof, and placing this on a joist. It is nailed to the joist with a nail from Yumi and fixed. However, there has been a problem that the nail is rusted after a long period of time, and the iron generated from the rust reacts with the lignin of the veneer to blacken the surface of the veneer. In addition, if stainless steel nails are used to prevent rust, there is a problem that the cost becomes extremely high.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wooden flooring material in which the rust of a nail does not easily cause contamination of a decorative surface.

[0004]

A wooden flooring material according to the above object is characterized in that an airtight sheet-like material is interposed between an upper part of a male fruit and a veneer veneer veneer on the surface. A wooden flooring that has actual processing on the four sides.

[0005]

FIG. 1 is a sectional view of a wooden flooring according to an embodiment of the present invention, and FIG. 2 is a sectional view of a wooden flooring according to another embodiment of the present invention. .

As shown in FIG. 1, a wooden flooring material according to an embodiment of the present invention comprises a veneer 1, a substrate 2, a sheet 3, a male 4, a female 5, and a nail 6. I have. Sheet 3
Are interposed between the protruding plate 1 and the substrate 2. As a material of the sheet-like material 3, the thickness with high airtightness is 0.01 to 0.1.
A synthetic resin sheet of about 2 m / m such as polyethylene or polypropylene is used.

As the substrate 2, a common wood substrate such as plywood, particle board, or MDF having a thickness of about 5 to 12 mm is used alone or in combination. 0.2-1.0 on the surface
A veneer 1 of about mm is adhered, and the surface of the veneer 1 is coated with urethane resin or the like.

A veneer plate 1 is adhered to a thin plywood having a thickness of about 2 to 3 mm or MDF via a sheet material 3 on the surface of the substrate 2 and a closed-cell synthetic resin sheet is provided on the back surface. When the decorative plate is attached, the sound insulation can be improved at the same time in addition to preventing the contamination by the nail 6. In addition, the junctions 4 and 5 are processed in the peripheral portion of the substrate.

Further, as shown in FIG.
A wooden flooring material in which an airtight sheet-like material 3 is interposed in a substrate constituted by F8 is also conceivable.

[0010]

According to the wood flooring material of the present invention, the air-tight sheet-like material is interposed between the veneer on the surface and the nail used for fixing the flooring material. To prevent the floor from being contaminated by the reaction of the veneer with lignin.
