Description

  The present invention relates to a flooring material that forms a floor surface of a wooden house or the like.

  Conventionally, a floor surface of a wooden house or the like is formed by, for example, arranging a plurality of flooring materials in parallel. This flooring material is generally provided with a male fruit and a female fruit, and is connected to an adjacent flooring material by engaging the male fruit and the female fruit (for example, , See Patent Document 1).

  Such a flooring material is generally formed to be relatively thin with a thickness of about 9 mm to 12 mm. For this reason, it has been difficult to sufficiently block the cold air from under the floor by the flooring material. Then, the cold air from under the floor was interrupted | blocked by providing a heat insulating material etc. under the flooring material.

  The flooring material is generally formed in a relatively narrow width of about 90 mm to 120 mm. One of the reasons why the flooring material is formed with a relatively narrow width is the occurrence of warpage. That is, when the width of the flooring material is relatively wide, warping due to moisture in the atmosphere is likely to occur. Such warping of the flooring material is caused by expansion of a portion where moisture is collected. In particular, moisture tends to collect on the lower end side of the flooring material, and as a result, the flooring material tends to be deformed with the interior side concave.

JP 05-331994 A

  As described above, the flooring material is generally formed in a relatively thin and narrow width. For this reason, when forming the floor surface provided with heat insulation, bases, such as a heat insulating material, are needed, and many flooring materials are needed. Therefore, there is a problem that the construction period of the floor surface becomes long and the cost increases.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a flooring material that is easy to construct and can form a floor surface excellent in heat insulation.

  A first aspect of the present invention that solves the above problem is a flooring material that forms a floor by arranging a plurality of base materials side by side on a base material, and has a convex portion that protrudes outwardly at one end in the width direction. And the other end in the width direction is provided with a recess having a size with which the protrusion engages, and the protrusion is formed so that the thickness thereof becomes thinner toward the tip side. The flooring material is composed of inclined surfaces that are continuous from the upper surface or the lower surface.

  According to a second aspect of the present invention, in the flooring material of the first aspect, the second paulownia board having the grain direction of the longitudinal direction is bonded to both surfaces of the first paulownia board having the grain direction of the transverse direction. It exists in the flooring material characterized by having a layer cross tension structure.

  According to a third aspect of the present invention, in the flooring material of the second aspect, the thickness of the first paulownia plate is thicker than the thickness of the second paulownia plate.

  According to such a flooring material of the present invention, the floor surface construction period can be greatly shortened, and a floor surface excellent in heat insulation can be formed.

It is a perspective view which shows the floor surface formed using the flooring material which concerns on one Embodiment of this invention. It is sectional drawing which shows the floor surface formed using the flooring material which concerns on one Embodiment of this invention. It is sectional drawing which shows the flooring material which concerns on one Embodiment of this invention. It is a figure which shows the construction procedure of the floor surface which concerns on one Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 3, a plurality of flooring materials 10 are arranged side by side on a base material 100 to form a floor surface (flooring floor) 1. In the flooring material 10 according to the present embodiment, the second paulownia plates 12 and 13 whose grain direction is the longitudinal direction (thickness direction) are bonded to both surfaces of the first paulownia plate 11 whose grain direction is the transverse direction. It has a three-layer cloth tension structure.

  The thickness of the first paulownia plate 11 and the second paulownia plate 12, 13 is not particularly limited, but the thickness of the first paulownia plate 11 is thicker than the thickness of the second paulownia plate 12, 13. It is preferable. For example, in this embodiment, the thickness of the first paulownia plate 11 is 17 mm, the thickness of the second paulownia plates 12 and 13 is 9 mm, and the total thickness of the flooring material 10 is 35 mm. Further, the width of the flooring material 10 is not particularly limited, but in the present embodiment, the width W1 of the upper surface 10a is formed to be about 400 mm.

  At one end portion of the flooring material 10 in the width direction (short direction), a protruding portion 14 that protrudes outward in the width direction is formed. On the other hand, the other end of the flooring material 10 in the width direction is formed with a recess 15 that is large enough to engage the protrusion 14. That is, each flooring material 10 constituting the floor surface 1 is fixed in a state where the convex portion 14 is engaged with the concave portion 15 of the adjacent flooring material 10.

  Here, the convex part 14 of each flooring material 10 is provided continuously over the longitudinal direction of the flooring material 10. Further, in the thickness direction of the flooring material 10, the convex portion 14 gradually decreases in thickness toward the tip 14a. And the surface of the convex part 14 is formed with the inclined surface 16a which continues from the upper surface 10a of the flooring material 10, and the inclined surface 16b which continues from the lower surface 10b. That is, the inclined surface 16a forming the surface of the convex portion 14 is inclined at a predetermined angle θ1 with respect to the upper surface 10a of the flooring material 10, and the inclined surface 16b is inclined at a predetermined angle θ2 with respect to the lower surface 10b of the flooring material 10. doing.

  On the other hand, the concave portion 15 is formed in a substantially V-groove shape so that such a mountain-shaped convex portion 14 is engaged. That is, the inner surface of the recess 15 is formed by an inclined surface 17a inclined at a predetermined angle θ1 with respect to the upper surface 10a of the flooring material 10 and an inclined surface 17b inclined at a predetermined angle θ2 with respect to the lower surface 10b of the flooring material 10. ing.

  In the present embodiment, the inclination angle θ1 of the inclined surface 16a and the inclination angle θ2 of the inclined surface 16b are made to coincide with each other, but these inclination angles θ1 and θ2 do not necessarily have to coincide with each other.

  By using the flooring material 10 to form the floor surface 1 of a wooden house or the like, the construction period of the floor surface 1 in the wooden house or the like can be greatly shortened. For example, since the flooring material 10 is formed wider than the conventional flooring material as described above, the number of sheets used is reduced. Furthermore, since the flooring material 10 is comprised with a paulownia board, and itself is formed comparatively thick, it is excellent in heat insulation. Therefore, installation of a heat insulating material becomes unnecessary by using the flooring material 10. Since the number of members used in this way is greatly reduced, the floor surface 1 of a wooden house or the like can be formed in a relatively short construction period.

  Moreover, the floor surface 1 is, for example, as shown in FIG. 4, a convex portion 14 of each flooring material 10 constituted by an inclined surface 16 a continuous from the upper surface 10 a and an inclined surface 16 b continuous from the lower surface 10 b at the end in the width direction. Is engaged with the recess 15 of the adjacent flooring material 10, and each flooring material 10 is fixed in this state. Since the mountain-shaped convex part 14 as described above can be engaged with the concave part 15 relatively easily, the floor surface 1 can be easily constructed. Further, by engaging the protrusions 14 with the recesses 15 in this way, the gaps between the flooring materials 10 can be reduced.

  In addition, a notch portion 18 in which a part of the flooring material 10 is notched is formed at the lower end portion of each flooring material 10 on the concave portion 15 side. That is, when the flooring 1 is formed by arranging the flooring materials 10 side by side, a space 19 having a predetermined size is defined between the flooring materials 10 by the notches 18.

  In this way, the notches 18 are formed in the flooring material 10, that is, the space portions 19 are defined between the flooring materials 10 constituting the floor surface 1. Can be suppressed. As a result, generation | occurrence | production of the curvature of the floor surface (flooring floor) 1 whole can be suppressed.

  Further, in the present embodiment, as described above, the thickness of the first paulownia plate 11 is larger than the thickness of the second paulownia plates 12 and 13. Thereby, the curvature of each flooring material 10 can be suppressed more effectively.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the invention.

  For example, in the above-described embodiment, the paulownia material is exemplified as the material of the flooring material 10, but the material of the flooring material 10 is not particularly limited.
