  Embodiments of the present invention will be described below.

  The building board 1 according to the present invention is formed in a rectangular shape as shown in FIG. 1, and has a plurality of ridges 2 provided on its surface in parallel to the left-right direction. If the effect of the present invention is not impaired, the plurality of ridges 2 and 2 do not have to be strictly parallel to each other, and may be substantially parallel to each other. Unless stated otherwise, the terms up, down, left and right refer to the direction in which the building board 1 is installed as an outer wall material (siding). The ridge 2 is formed in an elongated shape so as to protrude to the outdoor side of the building board 1. The ridges 2 are vertically adjacent to each other, and the ridges 4 are formed between the ridges 2 and 2 to form a horizontal stripe uneven pattern 7 on the surface of the building board 1. Since the number of convex stripes 2 provided on the surface of the building board 1 is not particularly limited, the number of concave stripes 4 formed therebetween is also not particularly limited. The vertical length of the building board 1 is about 250 to 1000 mm, the horizontal length is about 300 to 4200 mm, and the thickness is about 5 to 50 mm.

  The ridge 2 has, for example, a triangular cross section as shown in FIG. In this case, the triangle of the cross section may be an equilateral triangle, an isosceles triangle, or another triangle, but the length of the base is about 2 to 16 mm and the height is about 1 to 8 mm.

  The ridge 2 may have a trapezoidal cross section as shown in FIGS. In this case, the trapezoid of the cross section may be an isosceles trapezoid or any other trapezoid, but the length of the upper bottom is about 0.5 to 10 mm, the length of the lower bottom is about 3 to 24 mm, and the height is about 1 to 8 mm. is there.

  On the surface of the building board 1, a plurality of only one type of ridges 2 having the same cross-sectional shape may be provided, or as shown in FIG. 3, a plurality of types of ridges 2 having different cross-sectional shapes may be provided. When a plurality of types of ridges 2 are provided, the arrangement of these ridges 2 may be regular or irregular. The concave line 4 has an inverted triangular shape or an inverted trapezoidal shape in cross section due to the slopes of the adjacent convex lines 2.

  When the building boards 1 are vertically adjacent to each other and installed so that the ridges 2 and 2 of the respective building boards 1 are parallel to each other, the joints 3 are formed at the joining portions of the vertically adjacent building boards 1 and 1. The joint 3 may be formed as a groove having an inverted trapezoidal cross section as shown in FIG. 4A, or may be formed as an inverted triangular groove although not shown.

  Further, in the present invention, the first pseudo joint 41 and the second pseudo joint 42 are provided on the surface of the building board 1. The first pseudo joint 41 and the second pseudo joint 42 form part or all of the recessed line 4.

  The first pseudo joint 41 is mainly for making the joint joint 3 which is a joint portion between the building boards 1 and 1 inconspicuous, and is provided in parallel with the joint joint 3 between the adjacent ridges 2 and 2. Has been. If the effect of the present invention is not impaired, the first pseudo joint 41 and the joint joint 3 do not need to be strictly parallel, and may be substantially parallel. The number of the first pseudo joints 41 is not particularly limited, but it is preferable that the distance between the joint joint 3 and the first pseudo joint 41 and the distance between the first pseudo joints 41, 41 are equal to each other. Further, the first pseudo joint 41 has the same shape as the joint joint 3. For example, when the joint joint 3 is formed as a groove having an inverted trapezoidal cross section as shown in FIG. 4A, the first pseudo joint 41 also has an inverted cross section as shown in FIG. 4B. It is formed as a groove having a shape. The opening width W1 and the depth D1 of the first pseudo joint 41 are substantially equal to the opening width W0 and the depth D0 of the joint joint 3, and may not be exactly equal if the joint joint 3 is not conspicuous. The opening widths W0 and W1 of the joint joint 3 and the first pseudo joint 41 are about 1.5 to 18 mm, and the depths D0 and D1 are about 1 to 8 mm.

  Similarly to the first pseudo joint 41, the second pseudo joint 42 is also provided in parallel with the joint joint 3. The second pseudo joint 42 and the joint joint 3 do not need to be strictly parallel to each other and may be substantially parallel to each other as long as the effect of the present invention is not impaired. The second pseudo joints 42 are provided between the protrusions 2 and 2 different from the adjacent protrusions 2 and 2 on which the first pseudo joints 41 are provided. The number of second pseudo joints 42 is also not particularly limited. The second pseudo joint 42 is provided between the joint joint 3 and the first pseudo joint 41, or between the first pseudo joints 41 and 41. The interval between the second pseudo joint 42 and the joint joint 3, the interval between the second pseudo joint 42 and the first pseudo joint 41, and the interval between the second pseudo joints 42, 42 may be equal or unequal.

  Further, in the first aspect of the present invention, the second pseudo joint 42 has a width narrower than the width of the first pseudo joint 41 and has a depth equal to or less than the depth of the first pseudo joint 41, but has a cross-sectional shape. Are preferably similar. For example, when the first pseudo joint 41 is formed as a groove having an inverted trapezoidal cross section as shown in FIG. 4B, it is preferable that the second pseudo joint 42 also has a cross section as shown in FIG. 4C. Are formed as inverted trapezoidal grooves. The second pseudo joints 42 have a width narrower than that of the first pseudo joints 41, but when the widths are different depending on the depth like a groove having an inverted trapezoidal cross section, the width means the distance between the opposite opening edges. It means the opening width which is the distance. In this case, the opening width W2 of the second pseudo joint 42 is narrower than the opening width W1 of the first pseudo joint 41, and preferably 80% or less of the opening width W1 of the first pseudo joint 41. Further, the depth D2 of the second pseudo joint 42 is the same as or shallower than the depth D1 of the first pseudo joint 41, and preferably 0.5 to 7.5 mm. In particular, it is preferable that a plurality of types of second pseudo joints 42 having different depths D2 are mixed and provided on the building board 1.

  In the second aspect of the present invention, the second pseudo joint 42 has at least one of the width and the depth smaller than the first pseudo joint 41. That is, there are the following three cases.

  Firstly, there is a case where the second pseudo joint 42 has a width narrower than the width of the first pseudo joint 41 and a depth shallower than the depth of the first pseudo joint 41.

  Secondly, the second pseudo joint 42 has a depth shallower than the depth of the first pseudo joint 41. In this case, the width of the second pseudo joint 42 is the same as or wider than the width of the first pseudo joint 41, but is preferably the same as the width of the first pseudo joint 41.

  Thirdly, the second pseudo joint 42 has a width narrower than that of the first pseudo joint 41. In this case, the depth of the second pseudo joint 42 is the same as or deeper than the depth of the first pseudo joint 41, but is preferably the same as the depth of the first pseudo joint 41.

  Next, the effects of the first pseudo joint 41 and the second pseudo joint 42 in the present invention will be described with reference to specific examples.

  FIG. 6A shows an example in which two first pseudo joints 41 are provided in parallel on one building board at equal intervals and the second pseudo joints 42 are not provided. In the building board 1 as described above, the recessed lines 4 except for the second pseudo joints 42 may be provided, but the illustration thereof is omitted. Then, when two building boards 1 shown in FIG. 6(a) are vertically adjacent to each other and the lower end of the upper building board 1 and the upper end of the lower building board 1 are butted against each other, as shown in FIG. 6(b). However, since the first pseudo joint 41 has the same shape as the joint joint 3, it is difficult to distinguish the both, and the joint portion between the building boards 1 and 1 can be made inconspicuous.

  However, on the other hand, the line of sight to the joint joint 3 is also distributed to the first pseudo joint 41, so that the areas A1 and A3 surrounded by the joint joint 3 and the first pseudo joint 41 and the upper and lower first pseudo joints. It is conspicuous that the area A2 surrounded by 41 is one unit, and the whole area is composed of a plurality of units. For example, although the building board 1 is actually one building board 1, the building board 1 has the illusion that it is made up of three building boards each having areas A1, A2, and A3. To those who see.

  Therefore, in the present invention, in addition to the first pseudo joint 41, the second pseudo joint 42 having a predetermined width and depth is provided on the building board 1. That is, the building board 1 shown in FIG. 6A is the building board 1 further provided with the second pseudo joints 42, and is the building board 1 shown in FIG. 5A. In this building board 1, a second pseudo joint 41 is provided between the joint portion where the joint joint 3 is formed adjacent to another building board 1 and the first pseudo joint 41, and between the first pseudo joints 41, 41. Two joints 42 are provided in parallel at equal intervals. Then, when two building boards 1 shown in FIG. 5A are installed side by side adjacent to each other, it becomes as shown in FIG. 5B. When the surface of the building board 1 installed in this way is exposed to light, the second pseudo joints 42 differ from the first pseudo joints 41 in at least one of the width and the depth. The resulting shadows will be different. Therefore, when the second pseudo joint 42 is provided, the line of sight to the joint joint 3 and the first pseudo joint 41 can be weakened. Accordingly, it is possible to suppress the illusion that the whole is made up of a plurality of units, such as a plurality of building boards.

  As described above, in the present invention, the first pseudo joint 41 and the second pseudo joint 42 work together to make the joint joint 3 which is the joint between the building boards 1 and 1 inconspicuous. Further, it is possible to make it difficult to recognize that one building board 1 is composed of a plurality of units.
