DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, floor materials are generally rectangular, so that the workability and the design property by the arrangement of grooves and the like at the joints on the floor surface after the work are not always satisfactory.

[0003] In view of the above, a decorative material is formed by forming a real part for joining on the side part, which is entirely rectangular, and a plurality of long sides of the decorative material are joined to each other with an adhesive present in the real part. A structured flooring is provided. It has also been proposed to construct flooring materials by displacing decorative materials by a predetermined dimension in the longitudinal direction.

[0004] In the above-mentioned conventional flooring material, when an adhesive is applied to the real part and the decorative materials are fitted and bonded to each other, the adhesive oozes to the surface side and contaminates the surface of the decorative material. There were problems such as getting lost. Therefore, it is conceivable to reduce the amount of the adhesive applied as much as possible, but there are problems such as occurrence of poor adhesion.

[0005]

Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and comprises a female nut and a male nut having a protruding portion shorter than the depth of the female nut on a side surface portion. Adhesive is applied to a rectangular body formed and provided with an inclined portion for applying an adhesive to a lower portion of the female nut, and an adhesive is applied to the inclined portion at the male lower surface and the female lower portion so that the male and female nuts are formed. Mating
This is a flooring material characterized by being constituted by a plurality of bonded rectangular bodies.

According to the first and second aspects of the present invention, a female nut and a male nut having a projecting portion shorter than the depth of the female nut are formed on the side of the rectangular body. An inclined portion is provided, and an adhesive is applied to the lower surface of the male body on the side surface in the longitudinal direction of the rectangular body and the inclined part at the lower part of the female body. The reason for this is to prevent the treading caused by friction of the real part after construction by interposing an adhesive between the inclined part of the lower surface of the male and the lower part of the female, and This is because, by applying the adhesive to the lower surface and the inclined portion on the lower part of the female member, even if the amount of the adhesive is small, the rectangular body and the adhesive are well-adhered and the adhesion is good. In the invention according to claim 3, when the male body and the female body of a plurality of rectangular bodies are fitted and adhered to each other to form a floor material, the rectangular bodies are shifted by a predetermined dimension in the length direction, and the male body and the female body are shifted. The reason for fitting and bonding is to prevent the arrangement of grooves generated at the seam at the time of flooring from being linear.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view of the flooring material of the present invention, and is an enlarged view taken along the line AA in FIG. FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rectangular body 8 is made by attaching a decorative veneer such as a natural veneer or a veneer with an artificial grain pattern to the surface of a substrate made of plywood, LVL, MDF, particle board, or the like. It is made of solid natural wood. As shown in FIG. 2, on the four side surfaces of the rectangular body 8, male and female nuts 2 for joining are formed correspondingly. An inclined portion 3 for applying the adhesive 4 is formed below the female nut 2 by using a conventional cutting machine.

The inclined portion 3 at the lower part of the female nut 2 is
May be formed at the same time as the cutting formation, or may be separately formed in a later step. The inclined portion 3 formed at the lower portion of the female member 2 may be only the side portion in the length direction of the rectangular body 8. If the length of the protruding portion of the male member 1 is shorter than the depth of the female member 2, when the real portions of the rectangular body 8 are fitted and bonded to each other,
A gap is formed between the tip of the male seed 1 and the bottom of the female seed 2, and even when the amount of the adhesive 4 applied is increased, there is no danger of excess adhesive accumulating in the gap and oozing to the surface side. .

Further, as shown in FIG. 1, the peripheral edge of the rectangular body 8 is chamfered so that a groove 6 is formed between the adjacent rectangular bodies 8 when the rectangular bodies 8 are joined to each other. By doing so, it is possible to give a three-dimensional effect to the floor laying construction surface. The chamfering of the surface of the rectangular body 8 may be performed simultaneously with the actual forming. In FIG. 2, reference numeral 7 denotes a chamfer.

Using a plurality of rectangular bodies 8 obtained by the above process, their long sides are joined to each other. Rectangular body 8
As shown in FIG. 2B, the adhesive 4 is attached to the lower surface of the male member 1 formed on the long side of the rectangular body 8 and the inclined portion 3 provided at the lower portion of the female member 2 as shown in FIG. Is applied, and the fruits are sequentially fitted and bonded. By applying the adhesive 4 to both surfaces of the inclined portion 3 on the lower surface of the male 1 and the lower portion of the female 2, the adhesiveness between the adhesive 4 and both surfaces is improved. The bonding of the female seeds 2 is performed well.

The adhesive used in the present invention is not particularly limited as long as it is an ordinary woodworking adhesive.
It is selected according to various purposes. For example, when the whole flooring material is made flexible, a rubber-based adhesive or a hot-melt type adhesive is used. On the other hand, when considering production efficiency, it is preferable to use a hot-melt type adhesive or a reactive hot-melt type adhesive that cures by cooling.

When the adhesive 4 is applied to both surfaces of the inclined surface 3 on the lower surface of the male member 1 and the lower portion of the female member 2, a coating machine such as an airless spray is used to apply a dot or a line to a predetermined location. Apply to.

The rectangular bodies 8 to which the adhesive 4 has been applied are fitted and adhered with their long sides shifted by a predetermined dimension in the longitudinal direction. When the floor material is formed by joining the rectangular bodies 8 with each other by shifting the predetermined length in the length direction, both ends of the floor material become step-like, seams appear randomly after the floor material is laid, and the design of the floor surface is monotonous. Disappears. FIG. 3 shows an example of a combination of the rectangular bodies 8 to be fitted and bonded, but the present invention is not limited to this.

In the embodiment shown in FIG. 3, five rectangular bodies 8 are fitted and adhered, and then, as shown in FIG. It has a function of absorbing irregularities on the ground surface on which the material is laid and for absorbing shock generated on the surface of the rectangular body 8 after the construction.

When laying this floor material on a concrete floor slab surface or other lower ground, it is laid with an epoxy resin adhesive or a moisture-curable adhesive.

[0017]

As described above, the floor material according to the present invention has male and female nuts for fitting and bonding formed on the side surfaces, and has an inclined portion for applying an adhesive to a lower portion of the female nuts. Adhesive is applied to the inclined part of the lower surface of the male body and the lower part of the female body of the rectangular body provided with
Since the structure is formed by bonding, when walking after laying construction, the fruit does not rub and cause treading, and the adhesive does not ooze to the surface and contaminate the decorative surface. In addition, since the adhesive is applied to both the inclined surfaces of the male lower surface and the female lower surface, even a small amount of adhesive has good adhesive strength. Furthermore, if an adhesive that has flexibility after curing is used, the whole flooring material becomes flexible, and even when laid directly on the concrete floor slab surface with the adhesive, the propagation of the impact sound generated on the floor surface This has the effect of reducing the effect. In addition, since the rectangular bodies are fitted and adhered while being shifted in the longitudinal direction, the arrangement of the grooves formed on the construction surface of the flooring material appears not linearly but randomly, which is satisfactory in design.
