DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on one embodiment. FIG. 1 shows a vertical section of a floor material for direct application according to the present invention.

In FIG. 1, reference numeral 1 denotes a wooden substrate,
Functions as a core material for flooring. As the wooden substrate 1, 3
Ply to 7-ply plywood, particle board, OSB
(Oriented strand board), MDF (medium density fiber board), solid wood board, or a laminate of two or more of these can be used. In this embodiment, the wooden substrate 1 is a three-ply plywood having a thickness of 2.5 m.
m, width: 150 mm, length: 900 mm.

The wooden substrate 1 may be provided with a notch (not shown) extending from the back surface in the thickness direction in order to make the wooden substrate flexible. The direction in which the kerf extends extends in many cases in a direction parallel to the short side, but may be engraved to extend in the long side direction or both directions.

Reference numeral 2 denotes a restraining member, which is adhered to the back surface of the wooden substrate (1) via an adhesive. The constraining member 2 absorbs unevenness of the floor base surface by adapting and deforming according to the shape of the floor base surface, and also lowers the center of gravity of the floor material to suppress displacement of the floor material.
It functions to prevent lifting from the floor ground surface, prevent floor noise, and provide good walking.

As the restraining member 2, various recycled plastics can be used in addition to vinyl chloride resin, urethane resin, synthetic rubber resin, polyethylene resin, olefin resin. An inorganic powder having a high specific gravity, such as calcium carbonate, silica, alumina, carbon black, metal powder or metal oxide powder, is appropriately mixed into these resins to determine the specific gravity of the restraining material 2 and the specific gravity of the wood-based substrate 1 (0 .4 to 0.8). More preferably, the specific gravity of the wooden substrate 1 is twice or more. In this example, iron powder was mixed into a polyolefin resin to obtain a restraining material 2 having a specific gravity of 4.0 and a thickness of 1.0 mm.

The adhesive used when the restraining material 2 is adhered to the back surface of the wooden substrate 1 is, for example, a polyurethane resin, a vinyl urethane resin, vinyl acetate, ethylene vinyl acetate, an acrylic resin, or the like. Flexible adhesives are preferred.

Reference numeral 3 denotes a decorative layer, which is adhered to the surface of the wooden substrate 1 via a well-known adhesive such as a vinyl acetate resin. As the decorative material, it is possible to use a decorative veneer made of natural wood, for example, decorative paper on which woodgrain printing is performed, a vinyl chloride resin sheet, or the like. When the wooden substrate 1 is a solid wooden board, the decorative layer 3 may be formed by directly painting the surface. In this example,
A decorative paper having a thickness of 0.3 mm and subjected to woodgrain printing is attached to the surface of the wooden substrate 1 to form a decorative layer 4.

As shown in FIG. 1, reference numeral 4 denotes an adhesive tape, which is provided on the end of the back surface of the restraining member 2 on the side of the second joining portion 6 so as to extend in the longitudinal direction of the floor material. The pressure-sensitive adhesive tape 4 is a double-sided pressure-sensitive adhesive tape in this embodiment, and a commercially available double-sided tape can be used. The adhesive tape 4 is adhered to the back surface of the restraining material 2 by one adhesive surface, and the other of the adhesive surfaces is released by a release paper until a new floor material is adhered on the existing floor material. Is protected. In this example, thickness: 0.6 mm, width:
The one having a length of 40 mm is provided so as to extend in the longitudinal direction of the floor material and to be adhered to one surface of the back surface of the restraining material 2.

Reference numeral 5 denotes a first joint portion, and a lower joint piece 7 projects downward. The first joining part 5 is formed such that the layer of the wood-based substrate 1 is present on the upper surface of the lower joining piece 7.

Reference numeral 6 denotes a second joining portion, and the upper joining piece 8 projects upward. The second consolidation part 6 is formed such that the layer of the wood-based substrate 1 exists on the lower surface of the consolidation upper piece 8.

A joint may not be provided on the short side of the flooring material, but a joint similar to the long side may be formed on the short side adjacent to and perpendicular to the long side. it can. For example,
In the case of the flooring material shown in FIG. 1, a second joint portion may be provided on the short side at the end on the back side in the drawing, and the first joint portion may be formed on the short side at the opposite end. it can. Each of these decision parts,
It is formed after the restraining material 2 is attached to the back surface of the wooden substrate 1.

Next, a construction method when a new floor surface is formed on an existing floor using the floor material for direct application of the present invention will be described.

First, the existing floor surface is cleaned, and the second mating portion 6 is brought into contact with one wall surface in the room to be positioned, and the release paper of the adhesive tape 4 is peeled off to remove the floor material. Stick on the floor. After that, the first consolidation part 5 of the floor material adhered before.
Is positioned so that the upper joining piece 8 of the second joining member 6 of the next flooring material is placed on the upper surface of the lower joining piece 7 of the above. Peel off and stick the next floor material on the existing floor.

In this way, the first joining portion 5 of the previous flooring material is joined and fixed on the existing floor via the adhesive tape 4 by the second joining portion 6 of the next flooring material. Hereinafter, a new floor surface is formed on the existing floor in the order described above.

When only a part of the existing floor formed by using the floor material of the present invention is to be replaced, the second floor material of the adjacent floor material is leveraged by leveraging the existing floor material to be removed.
If the consolidation part 6 is slightly lifted, the floor material to be removed can be inclined to form a space for retreating the floor material, and the floor material to be removed is retreated in a direction parallel to the plate surface. The lower piece 7 of the first joining portion 5 of the floor material to be removed can be extracted from the second joining portion 6 of the existing floor material to be used.

Next, the lower joint piece 7 of the first joint part 5 of the new flooring material is removed in the reverse order to the above procedure, and the second jointing part 6 of the existing flooring material to be used from now on. Is inserted into the lower portion of the upper joining piece 8 to join the joining sections, and the release paper of the adhesive tape 4 on the new floor material is peeled off, and the new floor material is bonded and fixed to the floor surface. Thus, the desired floor material on the existing floor can be replaced with a new floor material.

[0025]

According to the present invention, the first joint portion of the floor material to be constructed next is securely pressed against the ground with the minimum necessary area without providing the adhesive tape on the entire back surface of the restraining material. Since it can be fixed and constructed, it can be made thinner than conventional floor materials. In addition, since the joining portion is in the form of a joint and the adhesive tape has a minimum area, it can be easily peeled off in a single sheet with a certain amount of force,
Remodeling can be done easily.
