[0017]
The four side edges of each convex block (5) are inclined at an angle θ (θ = 60 °) with respect to the upper surface of the convex block (5) as shown in FIGS. As shown in FIG. 4, an erosion collapse-like portion (5A) is formed in a concave shape on one side of the smooth surface of each convex block (5). The erosion collapse-like part (5A) eliminates the hard and cold feeling of the block-like pattern and gives a natural feeling. A fine uneven pattern may be formed on the smooth surface of the convex block (5).

Usually, 3 to 4 types of the pattern unit are set. In the pattern unit, the convex block (5) may be set with or without a fine uneven pattern on the smooth surface.
[0018]
In the building board (1), a strip-shaped board material (1A) having a width W may be cut out along a vertical direction from a predetermined location. This strip-shaped plate material (1A) is used, for example, as a corner member or a corner member at the corner of the outer wall. As shown in FIG. 7, the strip W (1A) has a width W of, for example, W ₁ = 70 mm and W ₂ = 101 mm. In the case of a 70 mm wide plate (1A), it is cut along the cutting line C _1. , if sheet material 101mm of (1A) cut along the line C _2.

In addition, the convex blocks (5) and the vertical grooves (3) at each stage were arranged so that six strip-shaped plate materials (1A) having a width W could be cut out. Specifically, in FIG. 7, the cutting line C ₁ is for cutting a strip-shaped plate material (1A) having a width W ₁ = 70 mm, and the cutting line C ₂ is for cutting a strip-shaped plate material (1A) having a width of 101 mm. The cutting interval of the plate material (1A) is set to 78.3 mm (a ₁ ) for the plate material (1A) having a width W ₁ = 70 mm, and 47.3 mm (a ₂ ) for the plate material (1A) having a width W ₂ = 101 mm. The The cutting lines C ₁ and C ₂ are 15 mm away from the upper surface vertical side E of the convex block (5) of each step.
[0021]
As in this embodiment, when the strip-shaped plate material (1A) having a predetermined width W is cut out from one end of the building plate (1), the strip-shaped plate material (1A) is cut at regular intervals (a ₁ or a ₂ ). Considering the arrangement of the convex blocks (5) and the vertical grooves (3) at each step so that they can be extracted, it is easy to determine the position of the cutting line C when cutting the plate (1A).
[0022]
Furthermore, in the present invention, as described above, a fine uneven pattern may be provided on the smooth surface of the convex block (5), but this fine uneven pattern may be provided on all the convex blocks (5) of the building board (1). It may be provided in a part.
Also, a plurality of types of the building board (1) are prepared, and the arrangement pattern of the convex blocks (5) arranged on the surface of the plurality of types of building board (1) is all common, and the building board ( 1) Plural types in which the position and / or shape of the erosion collapse-like portion (5A) of the smooth surface of the convex block (5) at the same position and / or the erosion collapse state are totally or partially different. If the building board (1) is appropriately selected and placed vertically and / or horizontally on the surface of the building frame, the repeated feeling of the pattern when the same kind of building board (1) is stretched is eliminated. It is possible to build structures such as the outer walls of rich designs. In this case, the smooth surface of the convex block (5) may be set with or without a fine uneven pattern.
