The female real part 4b, V-grooves 8 are formed between the first inclined surface 5a of one rectangular plate 2a and the third inclined surface 7b of the other rectangular plate 2b. . When the first inclined surface 5a of one rectangular plate 2a and the second inclined surface 6b of another rectangular plate 2b are in contact with each other, the surface on the back side of the one rectangular plate 2a A groove 9 is formed between the back surface of the other rectangular plate 2b.

  A building material 1 shown in FIG. 1 includes a rectangular plate 2, a male part 3 provided on a side surface of the rectangular plate 2, and a female provided on a side surface opposite to the side surface provided with the male part 3. And a real part 4. The rectangular plate 2 includes an upper member 21 and a lower member 22. The upper member 21 is made of a material having a smooth and hard surface on the front side such as MDF (Medium Density Fiberboard). Makeup is applied. As the upper member 21, a solid thick plate material may be used. The lower member 22 is made of a material having strength and thickness such as a plywood or a particle board. The total thickness of the building material 1 is generally 12 to 15 mm. The upper member 21 and the lower member 22 are bonded and integrated with each other.

  The male part 3 is provided on the side surface of the rectangular plate 2. On the other hand, the female real part 4 is provided on the side surface opposite to the side surface of the rectangular plate 2 on which the male real part 3 is provided. In the present embodiment, the male real part 3 and the female real part 4 are respectively provided on the lower member 22 constituting the rectangular plate 2. The male part 3 forms a substantially triangular prism. On the other hand, the female real part 4 is formed so as to be joined to the male real part 3 and forms a substantially triangular prism.

  In addition, if it is the side surface of the rectangular board 2, the male real part 3 and the female real part 4 may each be provided in the upper member 21, and are provided ranging over the upper member 21 and the lower member 22. Also good.

  The building material 1 has a first inclined surface 5. The first inclined surface 5 is inclined inward from above the male part 3 toward the front side surface of the rectangular plate 2 (the front side surface of the upper member 21). In this embodiment, the surface on the front side of the first inclined surface 5 and the surface on the upper side of the male part 3 are a series of surfaces.

  Thus, the surface to be cut can be reduced by making the surface on the front side of the male part 3 and the first inclined surface 5 into a series of surfaces. Therefore, the process of cutting the building material 1 is reduced, and the manufacturing of the building material 1 can be simplified.

  The building material 1 has a second inclined surface 6. The second inclined surface 6 is formed from the upper part of the female real part 4 to the boundary between the upper member 21 and the lower member 22 (substantially central part between the female real part 4 and the front side surface of the rectangular plate 2). Yes. The second inclined surface 6 has an outer inclination from above the female real part 4 toward the boundary between the upper member 21 and the lower member 22. In the present embodiment, the surface on the front side of the second inclined surface 6 and the surface on the upper side of the female real part 4 are a series of surfaces. Therefore, the manufacturing of the building material 1 can be simplified as described above.

  Furthermore, the building material 1 has a third inclined surface 7 that is inclined inward from the boundary between the upper member 21 and the lower member 22 toward the surface on the front side of the rectangular plate 2.

  Furthermore, the building material 1 has a fourth inclined surface 10 that is inclined inward from the lower side of the male part 3 to the back surface of the rectangular plate 2. Furthermore, the building material 1 has the 5th inclined surface 11 which has an outer side inclination to the approximate center part of the downward direction of the female real part 4 and the surface of the back side of the rectangular board 2. FIG. The fifth inclined surface 11 is formed to be substantially parallel to the fourth inclined surface 10. Furthermore, the building material 1 has a sixth inclined surface 12 having an inner inclination from the end of the fifth inclined surface 11 opposite to the female part 4 to the back side surface of the rectangular plate 2.

  The front surface of the fourth inclined surface 10 and the front surface of the male part 3 are a series. Moreover, the surface on the front side of the fifth inclined surface 11 and the surface on the front side of the female real part 4 are a series. Therefore, the manufacturing of the building material 1 can be simplified as described above.

  As shown in FIG. 2, when the first inclined surface 5a of one rectangular plate 2a and the second inclined surface 6b of the other rectangular plate 2b are in contact, one rectangular plate 2a. The building material 1 has a structure in which a groove 9 is formed between the back side surface of this and the back side surface of another rectangular plate 2b.

  Since the building material 1 has such a structure, even if the building material 1 contracts due to a change in humidity or the like, it is possible to perform a concave warp and a convex warp, respectively. Therefore, the building material 1a and the building material 2a are smoothly and smoothly adhered to each other, so that familiarity is improved.

  Note that the concave warp means that both ends of the building material 1 are lifted when the building material 1 is placed on a horizontal plane alone with the surface of the building material 1 facing upward. On the other hand, the convex warpage means that the central portion of the building material 1 is lifted when the building material 1 is placed on a horizontal plane with the front surface of the building material 1 facing upward.

  In addition, it is preferable that the groove | channel 9 between the back surface of one building material 1a and the back surface of the other building material 1b is also a V-groove. This is because if the shape of the groove 9 is similar to the shape of the V-groove 8, the building material 1 is more likely to make a concave warp and a convex warp, respectively.

  As shown in FIG. 3, when the building material 1 contracts due to a change in humidity or the like, the male real part 3a and the female real part 4b do not come into contact with each other. However, even if the building material 1 contracts, in this embodiment, the V-groove 8 is formed between the building material 1a and the building material 1b, as before the building material 1 contracts. Therefore, when the building material 1 is viewed from the front surface side of the building material 1, the bottom of the V groove 8 between the building material 1a and the building material 1b looks like a line as before the building material 1 contracts. Therefore, even if a gap occurs between the building material 1a and the building material 1b, the bottom of the V-groove 8 is not conspicuous, and the aesthetic appearance is not impaired so much.

[Second Embodiment]
Next, the structure of the building material 201 according to the second embodiment of the present invention will be described with reference to FIG. Furthermore, the state in which the building material 201 contracts will be described with reference to FIG. In the present embodiment, only differences from the first embodiment will be described.

  The male part 203 of the building material 201 forms a convex part. More specifically, the male part 203 is a substantially quadrangular prism. On the other hand, the female real part 204 forms a recess and is shaped to be joined to the male real part 203.

  On the other hand, the building material 201 in this embodiment is not provided with the sixth inclined surface 12. Instead, the fifth inclined surface 211 is inclined inward from the lower side of the female real part 204 to the back side surface of the rectangular plate 202.

  As shown in FIG. 5, when the building material 201 contracts due to a change in humidity or the like, a portion where the male real part 203 and the female real part 204 do not come into contact with each other is generated. However, even when the building material 201 contracts, the V-groove 208 is formed between the front surface of the building material 201a and the front surface of the building material 201b. When the building material 201 is viewed from the front surface side of the building material 201, the bottom of the V groove 208 formed between the building material 201a and the building material 201b looks like a line. Therefore, even if a gap occurs between the front surface of the building material 201a and the front surface of the building material 201b, the aesthetic appearance is not impaired.

  The fifth inclined surface 211 may be substantially perpendicular to the back surface of the building material 201 or may be inclined outward as long as the groove 209 is formed.
