The cushion layer 40 is formed on the lower surface thereof with a surface material fastener 6 to be described later provided on the floor material 5, and a floor material surface fastener 7 that can be engaged. This floor fastener 7 is attached to the lower surface of the cushion layer 40 with a double-sided tape or an adhesive.

On the upper surface of the floor base material 5, a belt-shaped base material surface fastener 6 engageable with the floor material surface fastener 7 is provided.
Are fixed at appropriate intervals. That is, a double-sided tape is previously attached to the back surface of the surface fastener 6 for base material, and the surface fastener 6 for base material integrated with the double-sided tape is attached to the floor base material 5. Next, the assembling of the construction structure of the flooring material according to the present embodiment and the operation will be described with reference to the illustrated example.

First, the assembly procedure will be described. As shown in FIG. 5, strip-shaped base material surface fasteners 6 are fixed to the upper surface of the floor base material 5 forming the base of the floor surface at appropriate intervals. More specifically, a double-sided tape or the like is previously attached to the back surface of the surface fastener 6 for base material, and the surface fastener 6 for base material integrated with the double-sided tape is attached to the floor base material 5 to form a base material. The surface fastener 6 can be fixed to the floor base material 5.

In this way, the floor material 10 is first placed from the corner of the room with respect to the surface material fastener 6 attached to the floor base material 5. At the time of this placement, by engaging the floor material surface fasteners 7 provided on the lower surface of the floor material 10 with the base material surface fasteners 6 provided on the floor base material 5, the floor material 10 is placed on the floor base material. It is to be laid on the material 5. In this way, the floor material 10 laid on the floor base material 5 is
As shown in FIG. 3, the floor material 10 is laid by sequentially connecting the other floor materials 10.

That is, as shown in FIG. 2, with respect to the female shingles 30 of the floor material 10 placed and fixed on the floor base material 5,
The tongue portion 20 of the other floor material 10 is inserted and connected. More specifically, in the vicinity of the opening entrance of the female tongue portion 30 formed by the downward engaging portion 12 and the upward engaging portion 14 of the floor material 10 mounted and fixed on the floor base material 5, another floor material 10 is provided. The tip protrusion 24 of the male part 20 is inserted obliquely from above, and the tip protrusion 24 of the male part 20 of the floor material 10 is inserted inside the female part 30.

Further, the floor material 10 placed and fixed further.
On the other hand, by pressing the floor material 10 on the inserting side downward, the fixing of the floor materials 10 of the floor material 10 is completed. FIG. 3 shows a state in which the connection between the floor materials 10 is completed. In this way, the plurality of floor materials 10 are sequentially assembled according to the above procedure.

Next, the operation of this embodiment will be described. As described above, the floor material surface fastener 7 provided on the floor material 10 and the base material surface fastener 6 provided on the floor base material 5 are engaged and connected to each other, so that the floor material 10 can be easily attached to the floor base material 5. Can be laid on. The floor material 10 is laid on the floor base material 5 by providing the floor material surface fasteners 7 and the base material surface fasteners 6 so that the floor material surface fasteners 7 and the base material surface fasteners 6 are provided. The positioning can be easily performed by the engagement of, and an adhesive or the like is unnecessary. Therefore,
This contributes to speeding up the construction.

Further, the above-mentioned male body portion 2 is added to the floor material 10.
Since 0 and the female shroud 30 are provided, it is not necessary to provide a fixing means such as a nail and the labor for fixing the nails can be saved.
Further, since the cushioning layer 40 is provided on the lower surface of the floor material 10, the cushioning property in walking can be good and the sound insulation property can be secured. Furthermore, since the floor material 10 is integrally formed by extrusion molding,
The length in the longitudinal direction can be arbitrarily adjusted, it can be applied to the case of laying in rooms of various sizes, and it can be provided as a member suitable for industrial production, that is, mass production.

In addition, in spite of being formed by the extrusion molding as described above, the surface of the fine powder of the cellulosic material is made to carry fine powder having a smaller diameter and harder than the fine powder. By coloring and molding the resin in which the produced powder is mixed, the resin is formed so as to have a wood grain pattern, so that a wood texture can be produced. Next, the effect of the present embodiment will be described with reference to the illustrated example.

As described above, since the male tongue portion 20 and the female tongue portion 30 are provided at both ends in the width direction of the floor material 10, when the floor material 10 is laid on the floor base material 5,
Each is easy to join. That is, since the floor materials 10 can be engaged with each other only by engaging the male tongue portion 20 of the floor material 10 and the female tongue portion 30 of the other floor material 10, other fixing means such as nails or adhesives can be provided. It has the effect of not requiring it.

Since the floor base material 5 is provided with the surface fastener 6 for the base material and the floor material 10 is provided with the surface fastener 7 for the floor material, when the floor material 10 is laid on the floor base material 5. The floor material 10 can be easily and quickly laid on the floor base material 5 by the engagement of the surface material fasteners 6 and the floor material fasteners 7. Further, since the cushioning layer 40 is formed integrally with the floor material 10, it is possible to ensure elasticity during walking. Further, the cushion layer 40 formed on the floor material 10 can absorb some unevenness of the floor base material 5, and therefore, it is not necessary to improve the construction accuracy of the floor base material 5, so that the construction can be speeded up.

Further, between the floor material 10 and the floor base material 5, in addition to the cushioning property of the cushion layer 40,
The cushioning properties of the base material surface fastener 6 and the floor material surface fastener 7 are effective in ensuring appropriate elasticity during walking and also in improving sound insulation.
Furthermore, since the flooring material 10 is formed so as to have a wood grain pattern, there is an effect that a wood texture can be created.

Next, a variation of this embodiment is shown in FIG.
It will be described based on. As shown in FIG. 4, the flooring 10
The sound insulation layer 60 can be formed inside the thickness direction of the. More specifically, the sound insulation layer 60 is formed in a sandwich shape between the upper portion of the hollow portion 50 provided in the floor material 10 and the surface of the floor material 10. The sound insulation layer 60 is formed by mixing foamed vinyl chloride at the same time as the floor material 10 is extruded.

As a result, the sound insulation effect of the cushion layer 40 provided on the floor material 10 can be further enhanced, as well as the sound insulation effect. If the floor material 10 is not provided with the sound insulation layer 60, the embodiment of the invention described in claim 1 is provided. In addition, in the above-mentioned embodiment, the floor material 10 is a resin obtained by mixing a powder prepared by supporting a fine powder having a diameter smaller than that of the fine powder on the surface of the fine powder of the cellulosic material and being hard. Although it has been described that it is formed by coloring and molding so as to have a wood grain pattern, if it is not formed of such a material, an embodiment of the invention of claim 1, claim 2 or claim 3 is provided. It will be.

Further, unless the shapes of the male tongue portion 20 and the female tongue portion 30 of the flooring material 10 are technically limited, an embodiment of the invention according to claim 1 or 2 is provided.
