FIG. 1 is a front view of a building board A1 (original board) before painting used in the present invention. 2 is an enlarged view of the upper left portion of the building board shown in FIG. 1, FIG. 3 is a lower sectional view of FIG. 2, and FIG. 4 is a side view of FIG.
A plurality of through joint concave portions a1 and a plurality of convex strips b1 are alternately formed on the surface of the building board A1. Moreover, the building board A1 has the real part f1 in an upper end.
The through joint recess a1 has, for example, a width of about 11 mm and a depth of about 3 mm (in the short direction of the building board A1), extends along the longitudinal direction of the building board A1, and is formed on the surface of the building board A1. It is formed continuously from one end to the other end. In the building board A1, the through joint recess a1 is provided at a pitch of about 54 mm in the short direction of the building board A1. The pitch of about 54 mm in the short-side direction of the building board A1 indicates that the distance from the center to the center is about 54 mm in the through joint groove a1 that is adjacent to the top and bottom across the protrusion b1. In addition, there is no restriction | limiting in particular in the up-and-down width, depth, and pitch of a through joint concave-line part.
The ridge b1 is formed by being partitioned by a through joint ridge a1 and is formed from the left end to the right end of the building board A1 in FIG. When the through joint recess a1 is provided at a pitch of about 11 mm and a pitch of about 54 mm in the short direction of the building board A1, the vertical width of the protruding section b1 is about 43 mm, and the short side of the building board A1 A plurality are formed in the direction. There is no restriction | limiting in particular in the up-and-down width of the protruding board part of the building board A1.

A plurality of decorative concave portions c1, a plurality of decorative convex portions d1, and a plurality of groove patterns e1 that form the design of the convex portion b1 are formed on the convex portion b1.
The decorative recess c1 extends in a direction orthogonal to the through joint recess a1 (in the building board A1, the short direction of the building board A1). The decorative recess c1 has a left and right (longitudinal direction of the building board A1) width of about 3 mm and a depth of about 1 mm, and is formed shallower than the through joint recess a1. In addition, the left-right width of the decorative recess c1 can be set to 2 to 5 mm, and the depth can be set to 0.8 to 3 mm (however, shallower than the through joint recess a1). If the left and right width of the decorative recess c1 is less than 2 mm, the decorative recess c1 becomes the same color as the decorative convex portion d1 during roll coating, and the design as a joint is inferior. If the left and right width of the decorative recess c1 exceeds 5 mm, the decorative recess c1 becomes too conspicuous when painted, making it difficult to express a brick stacking design, a tiled design, and a stone stacking design. When the depth of the decorative recess c1 is less than 0.8 mm, the color becomes the same as the decorative convex portion d1 during roll coating, and the design as a joint is inferior. When the depth of the decorative recess c1 exceeds 3 mm, the decorative recess c1 becomes too conspicuous when painted, and it becomes difficult to express a brick stacking design, a tiled design, and a stone stacking design.
Further, the decorative recess c1 of the building board A1 is formed at a pitch of 9 mm in the left-right direction of the ridge b1 (longitudinal direction of the building board A1). The decorative recess c1 can be formed at a pitch of 5 to 15 mm. If the pitch of the decorative recess c1 is less than 5 mm, the decorative recess c1 does not have a shape that can be perceived visually. If the left and right width of the decorative recess c1 exceeds 15 mm, the decorative recess c1 is too conspicuous and a pattern cannot be expressed. The total area of the decorative recess c1 in the ridge b1 is 33.3% of the total area of the ridge b1, but can be 25 to 60% of the total area of the ridge b1. If the total area of the decorative recesses c1 is less than 25% of the total area of the ridges b1, the decorative recesses c1 cannot take a pitch and width, and it is difficult to express a pattern even when painted. If it exceeds 60%, the decorative recess c1 will be too conspicuous when painted, and it will be difficult to express a brick stacking design, a tiled design, and a stone stacking design.

  A decorative convex portion d1 is formed in the convex strip portion b1 by being partitioned into a decorative concave portion c1. Since the decorative concave portion c1 is formed with a width of about 3 mm and a pitch of about 9 mm in the left-right direction of the convex strip portion b1, the left-right width of the decorative convex portion d1 is about 6 mm. Since the decorative concave portions can be formed at a pitch of 5 to 15 mm, the width of the decorative convex portion d1 can also be set to 5 to 15 mm. A groove pattern e1 is formed on the decorative convex portion d1. The groove pattern e1 has a V shape in cross-sectional view and is shallower than the decorative recess c1. The cross-sectional shape of the groove pattern e1 is not particularly limited, and may be a square shape or a W shape.
