  Embodiments of the present invention will be described below.

  The building board 1 according to the present invention is formed by arranging a plurality of tile-shaped convex portions 4 in a staggered manner through vertical joints 2 and horizontal joints 3 as shown in FIGS. 1 and 2. Each tile-shaped convex part 4 is usually a quadrangle, and the left and right tile-shaped convex parts 4 are arranged via the vertical joints 2 so that the vertical joints 2 are located at the approximate center of the upper and lower tile-shaped convex parts 4. The upper and lower tile-shaped convex portions 4 are arranged through the horizontal joint 3. Such a building board 1 can be manufactured by carrying out curing hardening after press-molding a cement-type molding material using a predetermined metal mold | die. The building board 1 is usually a quadrilateral, and the four sides of the building board 1 are not shown in the figure. So that it can be installed against.

  Each tile-shaped convex part 4 is comprised by the center part 5 and the left end part 8 and the right end part 9 of the both sides. The ratio of the width of each of the left end 8, the center 5 and the right end 9 is about 1: 2: 1, but is not limited to this ratio.

  The left and right sides of each building board 1 preferably pass through a plurality of vertical joints 2 as shown by broken lines B in FIGS. 1 and 2. Alternatively, the left and right sides of each building board 1 pass through the boundary line between the central portion 5 of the tile-shaped convex portion 4 and the left end portion 8 and the right end portion 9 on both sides thereof as shown by the broken line C in FIGS. It is also preferable. In either case, the butted portion between the building boards 1 adjacent to the left and right can be made inconspicuous. Moreover, it is preferable that the upper and lower sides of each building board 1 pass the horizontal joint 3 as shown by the broken line D in FIG. 1 or FIG. In this case, the abutting part between the building boards 1 adjacent to each other in the vertical direction can be made inconspicuous.

  A concave curved surface 6 is formed at the central portion 5 of each tile-shaped convex portion 4, and a flat surface 10 is formed at the left end portion 8 and the right end portion 9 of each tile-shaped convex portion 4. In FIG. 3, the concave curved surface 6 is formed so that the cross section in the horizontal direction (horizontal direction) is a convex curved surface downward, but the concave curved surface 6 is not limited to this. The radius of curvature (R) of the concave curved surface 6 is not particularly limited. Below, the building board 1 in which the concave curved surface 6 as shown in FIG. 3 was formed in the center part 5 of each tile-shaped convex part 4 is demonstrated.

  Next, the surface of the building board 1 as shown in FIG. 2 obtained by curing and curing is painted. This coating is preferably performed by inkjet printing, but may be performed using other methods. When coating is performed by inkjet printing, an ink receiving layer is formed after applying a sealer (primer) to the surface of the building board 1 in advance. In the painting, a checkered pattern is formed by painting the central portion 5 of each tile-shaped convex portion 4 with a dark color and painting the left end portion 8 and the right end portion 9 with a light color as shown in FIG. The As described above, among the attributes of the color to be painted (hue / lightness / saturation), with regard to the lightness, the central portion 5 is low and the left end portion 8 and the right end portion 9 are high, but the hue and saturation are particularly limited. Not.

  And as shown with the broken line B in FIG. 1, when the both right and left sides of each building board 1 pass through several vertical joints 2 up and down, when installing a plurality of building boards 1 against each other, it adjoins. The abutting portion between the building boards 1 is difficult to distinguish from the vertical joint 2 and can be made inconspicuous. At this time, the center part 5 of the tile-like convex part 4 located above and below the vertical joint 2 is divided at substantially the center. However, since the central portion 5 is painted in dark color, it is difficult to recognize that the central portion 5 is divided when the plurality of building boards 1 are installed so as to be abutted to the left and right. It is possible to make the butt portion between them inconspicuous. Such an effect becomes higher as the difference (contrast) between the dark color painted on the central portion 5 and the bright color painted on the left end portion 8 and the right end portion 9 increases.

  In addition, as shown by a broken line C in FIG. 1, the left and right sides of each building board 1 pass through the vicinity of the boundary line between the central portion 5 of the tile-shaped convex portion 4 and the left end portion 8 and the right end portion 9 on both sides thereof. In this case, when the plurality of building boards 1 are installed to be butt-matched to the left and right, the abutting portions between the adjacent building boards 1 are difficult to distinguish from the above-described boundary lines, and therefore can be made inconspicuous.

  Moreover, as shown with the broken line D in FIG. 1, when the up-and-down both sides of each building board 1 pass the horizontal joint 3, when installing a some building board 1 up and down, it installs adjacent building board 1. The abutting portion between them is difficult to distinguish from the horizontal joint 3 and can be made inconspicuous.

  Moreover, since the concave curved surface 6 formed in the central portion 5 of each tile-shaped convex portion 4 is three-dimensional, and the two-dimensional checkered pattern is formed on the entire building board 1, The design can be enhanced, for example, in harmony and giving a fresh impression.

  Also, the vertical joint 2 and the horizontal joint 3 are painted with an intermediate color between the dark color painted on the central portion 5 of each tile-shaped convex portion 4 and the light color painted on the left end portion 8 and the right end portion 9. Is preferred. That is, the brightness of the vertical joint 2 and the horizontal joint 3 is higher than that of the central portion 5 and lower than that of the left end portion 8 and the right end portion 9, but the hue and saturation of the vertical joint 2 and the horizontal joint 3 are not particularly limited. In this case, the design properties can be further enhanced as compared with the checkered pattern composed of the two kinds of colors having different lightness by combining the three kinds of colors having different lightness. Moreover, when the vertical joint 2 and the horizontal joint 3 are painted in an intermediate color, the left and right sides of each building board 1 pass through the plurality of vertical joints 2 and the upper and lower sides of each building board 1 pass through the horizontal joint 3. (See the broken lines B and D in FIG. 1) When the plurality of building boards 1 are installed in a vertical and horizontal fashion, the abutting portions between adjacent building boards 1 can be made less noticeable.

  Further, the vertical joint 2 and the horizontal joint 3 have different colors from the dark color painted on the central portion 5 of each tile-shaped convex portion 4 and the light color painted on the left end portion 8 and the right end portion 9. It is preferable that the above-mentioned light color is superimposed on a part of the vertical joint 2 and applied. Here, the color means a color attribute, and it is sufficient that at least one of hue, brightness, and saturation is different. Moreover, as a part of the vertical joint 2, the right and left both-sides edge of the vertical joint 2 can be mentioned, for example. When the vertical joint 2 and the horizontal joint 3 are painted as described above, the sharpness of the vertical joint 2 and the horizontal joint 3 is slightly lost. The butted portion between the building boards 1 can be made less noticeable.

  Moreover, it is preferable that the dark color of the center part 5 of each tile-shaped convex part 4 becomes so deep that it approaches the light color of the left end part 8 and the right end part 9. FIG. That is, it is preferable that the brightness of the central portion 5 is not uniform as a whole, and becomes lower as it approaches the left end portion 8 and the right end portion 9. As a result, the boundary between the dark color and the light color is emphasized, and the step between the central portion 5 and the left end portion 8 and the right end portion 9 is also emphasized, so that a concave curved surface 6 deeper than the actual object is formed in the central portion 5. It seems to be.
