However, the floor panel of the present invention is constructed while being flexed by utilizing the flexibility of the groove 14 described later,
At that time, a strong stress that bends or tears the substrate 11 is applied to the groove portion 14, and therefore it is desirable that the decorative sheet 12 has strength enough to withstand this stress and protect the substrate 11 from damage. Therefore, it is most desirable to use a decorative sheet made of a thermoplastic resin.

いる。On the back surface of the substrate 11, a plurality of narrow grooves 14 are provided in parallel at predetermined intervals in order to provide the substrate 11 with appropriate flexibility and improve workability in a narrow space. To be The groove 14 is conveniently formed by cutting with a saw, and its width W 1 is substantially equal to the thickness of the saw.
It is set to about 8 to 1.5 mm. In the example shown in FIGS. 1 and 2, the groove 14 is provided parallel to the longitudinal direction of the substrate 11.

はない。The formation of a plurality of parallel grooves on the back surface of the base material of the floor material itself is, for example, JP-A-6-158832, JP-A-6-158834, and JP-A-9-533.
As described in Japanese Patent Publication No. 19 and the like, it is well known. However, conventional flooring with a back groove has a width of about 300 mm.
Since the groove is formed with a narrow width of (1 shaku) or less, aiming at the effect of absorbing a slight unevenness of the floor base surface and the soundproofing effect, it is possible to improve the workability in a narrow space like the present invention. In the past, it has not been applied to wide floor panels for the purpose of improvement.

It may be provided in an oblique direction that is not parallel to the longitudinal direction or the width direction. Further, for example, 2 in the longitudinal direction and the width direction
It may be provided in parallel with a plurality of directions intersecting with each other, such as the direction (FIG. 3) or two directions of 45 degrees and 135 degrees with respect to the longitudinal direction.
【００２５】この様に、複数方向に平行に溝１４を設け

しい。By providing the grooves 14 parallel to a plurality of directions in this way, flexibility is imparted to the floor panel in a plurality of directions.
There is an advantage that workability is further improved. Considering workability during construction of the floor material, if the groove 14 is provided only in one direction, it should be provided in the longitudinal direction or the width direction, and if provided in a plurality of directions, the groove 14 should be provided in parallel with the longitudinal direction and the width direction. Is desirable.

０〜９０％程度とするのが良い。If the distance W 2 between the grooves 14 is too narrow, the strength of the floor panel will be weak, and if it is too wide, the flexibility of the floor panel will be insufficient, so it is preferable to set it to about 5 to 20 mm. Further, if the depth of the groove 14 is too deep, the strength of the floor panel becomes weak and the floor panel is easily broken at the groove 14 portion, or the floor 14 is strongly affected by unevenness of the floor base surface after construction, and thus the groove 14 portion is deeply damaged. The bending of the substrate 11 is likely to be conspicuous. On the other hand, if the floor panel is too shallow, the flexibility of the floor panel becomes insufficient.
It is good to set it to about 0 to 90%.

ある。Grooves 14 to 20 are formed on the entire back surface of the substrate 11.
Providing at intervals of mm is good in terms of flexibility during construction,
It may be easily affected by the small unevenness of the floor surface, which may cause a phenomenon that the floor looks distorted after construction (especially, it is easily noticeable due to reflection of oblique light). On the other hand, in order to prevent this phenomenon, if the interval between the grooves 14 is set wider than 20 mm,
The flexibility of the floor panel may be insufficient, which may reduce the workability and may cause a breakage accident during the work.

い。In order to solve the above-mentioned problems, as shown in FIGS. 1 and 2, the grooves 14 are provided at intervals of 5 to 20 mm for 3 to 10 mm.
This groove group 1 is formed by forming parallel grooves to form one groove group 15.
5 are preferably arranged in parallel at a distance W 4 wider than the distance W 2 between the grooves 14. The number of the grooves 14 included in the groove group 15 is
All the groove groups 15 may be the same, or of course, the groove groups 15 including different numbers of the grooves 14 may be mixed.

ある。In this way, the groove group 15 provided with a plurality of the grooves 14 at a narrow interval W 2 of 5 to 20 mm ensures sufficient flexibility for construction on the floor panel, and the groove group 15 has Since it is difficult to pick up the unevenness of the floor base surface which is finer than the interval W 4, it is possible to effectively prevent the appearance failure due to the distortion of the floor surface after the construction. Further, since the groove 14 has a wide interval, it is advantageous in terms of strength of the floor panel.

Further, depending on the number of the grooves 14 in the groove group 15 and the like, if the interval W 4 between the groove groups 15 is narrower than the width W 3 of the groove groups 15, the above effect is substantially difficult to obtain. The interval W 4 between the groups 15 is preferably wider than the width W 3 of the groove group 15. On the other hand, if the width is too wide, the flexibility of the floor panel is reduced and the workability is affected.

If the groove group 15 is provided too close to the end portion, when the end portion is lifted and bent to perform the construction, the groove group 15 near the end portion is damaged or bent when bent. It is desirable that the groove group 15 is formed at a distance W 5 of at least 50 mm or more from the edge of the substrate, because the latter tends to remain after the work. Regarding the upper limit of the distance W 5 between the substrate end and the groove group 15, as in the case of the distance W 4 between the groove groups 15,
It is desirable to set it to 200 mm or less.
