  First, common items of the floor materials 1, 1A, 1B, 1C, and 2 according to these embodiments will be described. These floor materials 1, 1A, 1B, 1C and 2 are installed on a floor base 5 which is a so-called free access floor having a space for arranging electric wiring and the like under the floor. The floor base 5 on which the floor materials 1, 1A, 1B, 1C, and 2 are installed is not limited to the free access floor.

  Each of these floor materials 1, 1A, 1B, 1C, and 2 is a substantially rectangular flat plate, and in this embodiment, it is elongated in one direction as shown in FIGS. 1 and 4. The length dimension, width dimension, thickness dimension and the like of the floor material 1 are not particularly limited. For example, the floor materials 1, 1A, 1B, 1C and 2 may have a length dimension of about 600 mm to 1200 mm, a width dimension of about 100 mm to 200 mm, and a thickness dimension of about 3 mm to 30 mm. May have even smaller dimensions. Further, the floor materials 1, 1A, 1B, 1C, and 2 may be plate-shaped bodies having a length dimension of about 1500 mm to 2000 mm and a width dimension of about 250 mm to 500 mm.

  Each of these floor materials 1, 1A, 1B, 1C, 2 has a substantially rectangular plate-shaped base material 10, 20 as shown in FIG. 1 (a) (b) and FIG. 4 (a) (b). It is configured to have. On the short side edge portions 11 and 21 of the plate-shaped substrates 10 and 20, a real portion (male portion 11a on one side, a male real portion 11a, which can be combined with the floor materials 1, 1A, 1B, 1C, and 2 installed adjacent to each other. 21a and, on the other hand, female parts 11b, 21b).

  The plate-shaped substrates 10 and 20 may be formed of a wood-based substrate, a synthetic resin-based material, an inorganic material, a metal-based material, or the like, or may be formed of a plurality of materials. For example, the plate-shaped substrates 10 and 20 are made of wood such as plywood, wood laminated boards such as LVL (single board laminated material), wood boards such as particle boards, wood such as MDF (medium density fiber board) and HDF (high density fiber board). It may be formed from a wood board such as a fiber board. Further, the plate-shaped substrates 10 and 20 may be wooden plastic boards.

  Further, surface materials 18, 28 are laminated on the surfaces of the plate-shaped base materials 10, 20. As the surface material 18, 28, a veneer or other veneer formed by processing natural wood (name wood), a decorative printing paper on which various patterns (patterns) such as a wood grain pattern are printed, an olefin-based material, etc. It may be a synthetic resin film, a stone material, a glass material, or the like. Further, the surface materials 18 and 28 may be heat-treated veneer plates and coated with a flow coater, a roll coater, or the like. Note that, in the illustrated example, the surface of the plate-shaped substrates 10 and 20 is shown to be a flat surface, but a decorative groove or the like may be provided on the surface side.

  A soft thin sheet material such as resin or rubber may be attached to the back surfaces of the plate-shaped base materials 10 and 20 in order to prevent displacement from the floor base 5. In addition, when applying the flooring materials 1, 1A, 1B, 1C, and 2, the back surface of the plate-shaped substrate 10, 20 is coated with an agent capable of being peeled off or adhered, or a double-sided tape is attached. May be.

  Next, the floor materials 1, 1A, 1B, and 1C according to the first embodiment will be individually and individually described with reference to FIGS. 1 to 3.

  In the flooring material 1 shown in FIG. 1, the female part 13 is formed on both of the long side edges 12 of the plate-shaped substrate 10. That is, in the long side edge portion 12, the concave groove 13a is formed at the center in the thickness direction, the front surface side protrusion 13b is formed on the groove 13a, and the rear surface side protrusion 13c is formed on the lower side. The convex portion 14 is formed so as to project in one of the concave grooves 13a on both sides. It should be noted that it is desirable that both female solid portions 13 of the long side edge portion 12 have the same shape.

  In the example of FIG. 1, the convex portions 14 are provided at two places on the end side of the long side edge portion 12 and one place at the center, but not limited to this, and the number is not limited to this. Alternatively, only one location may be provided. It is desirable that the convex portion 14 be retrofitted with various materials. For example, as shown in FIG. 1C, the nail 14a may be driven, but the screw 25a (see FIG. 4), a wire, a resin material (for example, a PP band), rubber, or the like is fixedly provided. You can do it like this. Wires, PP bands, and rubber may be processed and used. When using the nail 14a, the screw 25a (see FIG. 4), the wire or the like, it is desirable to cover them with the rubber tube 14b or the resin tape for safety, but the convex portion 14 may be composed of only these. In the example of FIG. 1, the nail 14 a and the rubber tube 14 b are used as the convex portion 14.

  As shown in FIG. 1 (c), the convex portion material formed by the nail 14 a is driven into the bottom portion 13 aa of the concave groove 13 a so as to be parallel to the surface of the flooring 1 and covered with the rubber tube 14 b to form the convex portion 14. Just configure it. As shown in FIG. 1C, the convex portion 14 formed in this manner protrudes longer than the front surface side protrusion 13b on the upper side of the concave groove 13a. It is desirable that the protrusion dimension L1 of the convex portion 14 from the side end of the front surface side protrusion 13b be smaller than the depth dimension of the concave groove 13a. Further, it is desirable that the dimension L2 of the convex portion 14 in the thickness direction of the plate-shaped substrate 10 substantially matches the width dimension of the concave groove 13a. In the case where the convex portion 14 is configured only by the nail 14a, the dimension of the portion (at least the head in the case of the nail 14a) of the protrusion of the convex portion 14 that enters the concave groove 13a is the width dimension of the concave groove 13a. Should substantially match

  This floor material 1 is installed and constructed on a floor base 5, as shown in FIG. In the illustrated example, the long side edges 12 are aligned in the longitudinal direction of the flooring 1 and the short side edges 11 are displaced in the short side direction. The floor materials 1 in the longitudinal direction of the floor material 1 are joined by the male and female parts 11a and 11b shown in FIG. 1 (b).

  The floor materials 1 in the lateral direction of the floor material 1 are joined to each other by the convex portion 14 and the female part 13 of the adjacent floor material 1. Specifically, as shown in FIGS. 2 (a) and 2 (b), the convex portions 14 are fitted into the concave grooves 13 a of the mating female part 13 to join the floor materials 1 to each other. It

  Thus, the convex portion 14 is coupled to the female solid portion 13 instead of the male solid portion. That is, one of the long side edge portions 12 (the side on which the convex portion 14 is not provided) is joined by the convex portion 14 of the adjacent flooring 1 entering the concave groove 13a, and the other side of the long side edge portion 12 (the convex portion). On the side (provided with the portion), the convex portion 14 is inserted into the concave groove 13a of the adjacent floor material 1 so that both floor materials 1 are joined.

  In this way, both the short-side edge portion 11 and the long-side edge portion 12 are firmly joined to the adjacent floor material 1 and cannot easily come off after the construction. In particular, if the floor materials 1 are bonded to each other as described above, even if the floor base 5 is uneven, a lift (step) at the bonding portion between the floor materials 1 is unlikely to occur.

  Further, in the example of this drawing, since the long side edge portions 12 are provided with the plurality of convex portions 14, the long side edge portions 12 are firmly joined. At the center in the longitudinal direction, since the convex portion 14 is provided at the center in the longitudinal direction as shown in the figure, when the adhesiveness of the flooring material 1 is reduced or when the flooring material 1 warps, It is possible to prevent lifting (generation of a step) at the central portion in the direction. If the convex portions 14 are provided at three or more locations including both end portions and the central portion of the long side edge portion 12, it is possible to prevent the entire length from rising.

  Further, since the convex portion 14 is provided not on the entire length of the long side edge portion 12 but on a part thereof, when exchanging a part of the flooring material 1 by reforming, etc., insert a jig or the like between the convex portions 14, The floor material 1 can be easily peeled off by lifting it in an arch shape.

Next, another example of this embodiment will be described.
FIGS. 3A, 3B, and 3C are diagrams for explaining other three examples (floor materials 1A, 1B, and 1C) in the present embodiment.

  Floor materials 1A and 1B shown in FIGS. 3A and 3B are provided with a plurality of convex portions 14 on both sides of the long side edge portion 12. In FIG. 3A, the convex portion 14 is provided at a line symmetrical position (the same position along the longitudinal direction), and in FIG. 3B, the convex portion 14 is provided at a point symmetrical position. It should be noted that the female real parts 13 are formed on both long side edge parts 12 and the real part of the short side edge parts 11 are the same as those in FIG.

  Since the convex portions 14 are provided on both of the long side edge portions 12 in this manner, the floor members 1A and 1B adjacent to each other can be more firmly coupled. In addition, in the flooring 1B of FIG. 3B, the convex portions 14 are not provided at the same position in the longitudinal direction on both long side edge portions 12. Therefore, when the floor materials 1B are not installed as shown in FIG. 2A but are installed side by side so that the short-side edge portions 11 are in a straight line, the positions of the convex portions 14 between the adjacent floor materials 1B are positioned. It can be installed reliably without overlapping.

  Further, in the flooring 1C shown in FIG. 3C, the female part 13 is formed on one of the long side edge parts 12, but not on the other side. A convex portion 14 is formed at the center in the thickness direction of the flat side edge 12a of the long side edge portion 12 where the female portion 13 is not formed. Such a convex portion 14 is inserted into the concave groove 13a of the female portion 13 of the adjacent floor material 1 to connect the floor materials 1 to each other.

  According to this flooring material 1C, since the female side portion 13 of the long side edge portion 12 needs to be processed in only one side, the processing may be small and the manufacturing processing cost can be reduced. In addition, there is little waste of material.

  As in the various examples of the present embodiment described above, in the flooring materials 1, 1A, 1B, 1C according to the present embodiment, the convex portion 14 is provided on at least one of the long side edge portions 12. Good. The female portion 13 may or may not be formed on the long side edge portion 12 provided with the convex portion 14.

  That is, each of the floor materials 1, 1A, 1B, 1C has a female part 13 on one of the long side edges 12 of the plate-shaped substrate 10, and the long side edge 12 on the other side of the long side edges 12. It is sufficient to have a convex portion 14 protruding laterally corresponding to a part of the position in the longitudinal direction. Then, it is sufficient that the convex portion 14 engages with the female solid portion 13 between the adjacent long side edge portions 12 of the floor materials 1 to be installed.

  Next, the flooring material 2 according to the second embodiment will be described with reference to FIGS. 4 and 5.

  The flooring 2 shown in FIG. 4 includes a protruding strip 23 that projects laterally on the front surface side and a recessed strip 24 below the protruding strip 23 on each of the long side edge portions 12 of the plate-shaped substrate 20. The long side edge portion 22 has a convex portion 25 protruding longer than the protruding strip 23 provided at a part of the long side edge portion 22 in the longitudinal direction.

  In the example of FIG. 4, the protrusions 25 are provided at two places on the end side in the longitudinal direction and one place at the center, but not limited to this, and the number may be any other number. There may be only one location. As in the case of FIG. 1, it is desirable that the convex portion 25 be retrofitted with various materials such as nails 14a (see FIG. 1), screws 25a, wire, resin material (for example, PP band), rubber and the like. When using the nail 14a (see FIG. 1), the screw 25a, the wire, etc., it is desirable to cover with a rubber tube 25b or a resin tape for safety. In the example of FIG. 4, the screw 25a and the rubber tube 25b are used as the convex portion 25.

  As shown in FIG. 4 (c), the convex material is driven by the screw 25 a into the bottom 24 a of the groove 24 so as to be parallel to the surface of the flooring 2 and covered with the rubber tube 25 b. Should be configured. As shown in FIG. 4C, the protrusion 25 formed in this manner protrudes longer than the protrusion 23 on the upper side of the recess 24. The projecting dimension L3 of the convex portion 25 from the side end of the projecting strip 23 is preferably smaller than the depth dimension of the recessed strip 24. Further, the upper edge of the convex portion 25 may substantially match the lower edge of the protruding strip 23. The dimension L4 of the convex portion 25 in the thickness direction of the plate-shaped substrate 10 may be smaller than the width dimension of the concave line 24.

  This floor material 2 is installed and constructed on a floor base 5, as shown in FIG. In the illustrated example, the long side edge portions 22 are arranged in a straight line in the longitudinal direction of the floor material 2, and the short side edge portions 21 are displaced in the short side direction. The floor materials 2 in the longitudinal direction of the floor material 2 are joined by the male and female parts 21a and 21b shown in FIG. 4 (b).

  The floor materials 2 in the lateral direction of the floor material 2 are joined by the convex portions 25 entering the concave stripes 24 and the upper edges of the convex portions 25 contacting the lower edges of the protruding stripes 23. That is, between the adjacent long side edge portions 22 of the flooring materials 1, the convex portions 25 enter the concave stripes 24 and engage with the protruding stripes 23.

  As shown in FIGS. 5 (b) and 5 (c), when one floor material 2 is focused on, one long side edge portion 22 thereof partially acts as a male portion and another one of the long side edge portions 22 thereof. Will act as a female part.

  Thus, also in the case of the floor material 2 of the present embodiment, both the short side edge portion 21 and the long side edge portion 22 are firmly joined to the adjacent floor material 1 and cannot be easily removed after the construction. In particular, if the floor materials 1 are joined to each other in this manner, even if the floor base 5 is uneven, rises (steps) at the joints between the floor materials 1 are unlikely to occur.

  Further, in the example of this drawing, since the long side edge portions 22 are provided with the plurality of convex portions 25, the long side edge portions 22 are firmly joined. At the center in the longitudinal direction, since the convex portion 25 is provided at the center in the longitudinal direction as shown in the figure, even if the adhesiveness of the floor material 2 is reduced or the floor material 2 warps, It is possible to prevent lifting (generation of a step) at the central portion in the direction. It is more preferable to provide the convex portions 25 at three or more places including both ends and the central portion of the long side edge portion 22.

  Further, since the convex portion 25 is provided on both of the long side edge portions 22 of the floor material 2, a stronger bonding relationship can be formed between the floor material 2 and the adjacent floor material 2. In other words, the one long side edge portion 22 acts as both the male and female parts, so that the connection becomes strong.

  Further, since the convex portion 25 is provided not on the entire length of the long side edge portion 22 but on a part thereof, when exchanging a part of the floor material 2 by reforming or the like, insert a jig or the like between the convex portions 25. The floor material 2 can be easily peeled off by lifting it in an arch shape.
