Abstract

PROBLEM TO BE SOLVED: To obtain a flooring member by which a space is not formed between the flooring member and a surface in a rectangular flat flooring member where a tenon and mortise are respectively provided on one side part and the other side part which are parallel to each other by providing a groove parallel to the tenon along the male substance side of the back. SOLUTION: A flooring member 1 where an adhesive 12 is applied to the back 1a thereof is placed on a surface material 11. In such a condition, a groove space H is formed in a groove 4 part between the back 1a of the flooring member 1 and the surface material 11. Subsequently, a nail 13 is driven from the upper side of a tenon 2 obliquely inwards through the flooring member 1 into the surface material 11 to fix the flooring member 1 on the surface material 11. In this case, the nail 13 has the tip projected into the groove 4 of the back 1a to be driven into the surface material 11 through the groove space H. Though cracks or the like are caused in the back 1a of the flooring member 1 by the nail 13, the cracks are accommodated in the groove space H so that the floor material 1 will not be lifted from the surface material 11 by cracks or the like. Thus, it is possible to obtain a floor material by which a space is not formed between the floor material and the surface material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material used for floors of buildings such as houses, shops, educational facilities and the like.

[0002]

2. Description of the Related Art As a floor material used for floors of buildings such as houses, stores, educational facilities, etc., as shown in FIG. 4, a long flat plate-shaped member has conventionally been used. A plate member, that is, a floor member 10 provided with a male (convex) member 2 at the portion and a female (concave) member 3 at the other side is used. The floor material 1
0 is not limited to the long member shown in FIG.
As long as it is a rectangular plate-like member having parallel opposing sides, a short member may be used. As a method for applying the floor material 10, an application method using a nail adhesive is generally used. That is, FIG.
As shown in FIG. 1, a floor material 10 coated with an adhesive 12 such as a vinyl acetate resin is placed on a back surface 10a of a base material 11 such as a joist and a discarded plywood, and on one side of the floor material 10,
The nail 1 penetrates through the flooring 10 obliquely inward from above the male 2
3 is fixed, and the floor material 10 is fixed to the base material 11. Back 1
Next, the floor material 10 having the adhesive 12 applied thereto is placed on the base material 11 while fitting the female fruit 3 with the male 2 of the floor material 10 previously fixed. Flooring 10 in the direction
And the nail 13 is driven into the base material 11 to fix the floor material 10 to the base material 11. In the same manner, the floor material 10 is sequentially fixed to the base material 11 to form a floor.

[0003]

The conventional flooring material and the construction method therefor have the following problems due to the construction as described above. That is, as shown in FIG. 6, there is no escape place for the distortion corresponding to the volume of the nail 13 driven into the floor material 10, and a crack or bulge 10 b protruding due to the driving of the nail 13 is formed on the back surface 10 a of the floor material 10. Occurs. As a result, the floor material 10 is lifted by the protruding cracks or ridges 10b, and the gap space G is formed between the floor material 10 and the base material 11 over a wide range. On the floor in which such a gap G is formed, a squeaking phenomenon that generates abnormal noise when walking on the floor surface occurs, and the squeaking space G is a cause of the squeaking phenomenon.

The nail 10 is driven into the back surface 10 of the floor material 10.
The tendency of the protruding cracks or ridges 10b to occur on a is remarkable when the wood material has a large specific gravity, particularly when the specific gravity is 0.7 or more. In the case of a long fiber material, the material is sticky, and the fibers around the nail 13 tend to be pushed up on both sides of the nail 13 and protrude. In the case of a short fiber material, the material is not sticky and brittle. The fibers around the nail 13 tend to protrude due to chipping and cracking. Also,
In order to improve the sound insulation performance of the floor, a cushioning material such as hard rubber or compressed urethane foam is often used for the base material 11, but the adhesive 12 is difficult to adhere to these cushioning materials. Does not work, or has low adhesion even when bonded. Therefore, the back surface 10 of the flooring 10 is driven by the driving of the nail 13.
A protruding crack or ridge 10b cannot be suppressed by adhesive force, and the gap space G tends to be large.
If a preliminary hole into which the nail 13 is driven is formed in the floor material 10 in advance, or if a prepared hole is processed at the time of floor construction, a protruding crack or bulge 10b of the back surface 10a of the floor material 10 due to the driving of the nail 13 is formed. Although it can be suppressed, it is very difficult to implement and is not a practical method.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and in the method of using a floor material with a nail adhesive in combination with a base material, no gap space is formed between the floor material and the base material. The purpose is to provide flooring.
