Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[Embodiment 1]
As shown in FIG. 1, the building board of the present embodiment is an outer wall material, and is composed of, for example, a ceramic siding material. The building board of the present embodiment can be used for both horizontal (horizontal installation) and vertical (vertical installation), but in the following, the description will be based on the horizontal installation. do. Therefore, the direction parallel to the vertical direction is defined as the width direction, the direction parallel to the left-right direction is defined as the length direction, and the direction orthogonal to the width direction and the length direction is defined as the front-back direction. In addition, a plane orthogonal to the front-rear direction on a building board may be referred to as a main surface. The shades appearing on the surface of the base material 1 as shown in FIG. 1 are not painted separately, but are due to the shadows appearing on the surface.

The building board is mainly composed of the base material 1. The base material 1 is a molded product before being painted, and is composed of, for example, a ceramic-based base material. As shown in FIG. 1, the surface of the base material 1 is divided into pseudo joints extending in the width direction (hereinafter, vertical joints 11) and pseudo joints extending in the length direction (hereinafter, horizontal joints 12). A plurality of rectangular convex portions 13 are formed. The plurality of rectangular convex portions 13 and the joints 11 and 12 are formed by forming an uneven shape on the surface of the base material 1 by using, for example, a press die.

The building board of the present embodiment includes a planar convex portion 131 and a three-dimensional shape portion group 132 as a plurality of rectangular convex portions 13. The front surface of the planar convex portion 131 is formed flat. The three-dimensional shape portion group 132 is configured by gathering a plurality of three-dimensional shape portions 22, 31 on the front surface. The building board of the present embodiment includes two types of three-dimensional shape portion groups 132 (referred to as a first three-dimensional shape portion group 2 and a second three-dimensional shape portion group 3) as the three-dimensional shape portion group 132.

FIG. 2 shows an enlarged view of the first three-dimensional shape portion group 2. The first three-dimensional shape portion group 2 includes a plurality of flat surface portions 21 and a plurality of three-dimensional shape portions 22. The flat surface portion 21 and the three-dimensional shape portion 22 are formed with reference to a reference plane. Here, the reference plane is a planar virtual plane orthogonal to the front-rear direction, and in the present embodiment, the reference plane is located behind the front surface of the planar convex portion 131 and in front of the bottom surfaces of the joints 11 and 12. It is stipulated.

The flat surface portion 21 is formed of a flat surface whose height coincides with the reference surface and is parallel to the reference surface, and is a rhombus (hereinafter referred to as a front view) when viewed in a direction facing the reference surface (hereinafter referred to as a front view). A square inclined by 45 ° with respect to the direction, in other words, a square in which one diagonal line is parallel to the length direction of the base material 1) is formed. Further, the flat surface portion 21 is located on the same plane as the reference plane. The flat surface portions 21 are arranged in the central portion in the vertical direction of the first three-dimensional shape portion group 2, and a plurality of the flat surface portions 21 are arranged side by side in the left-right direction (length direction of the base material 1). That is, the flat surface portion 21 is formed in the region of the first three-dimensional shape portion group 2.

The three-dimensional shape portion 22 is a portion having a shape formed three-dimensionally on the reference plane. The three-dimensional shape portion 22 in the first three-dimensional shape portion group 2 is composed of a pyramidal-shaped convex portion 23 protruding forward from the reference plane. The pyramid-shaped convex portion 23 of the present embodiment is specifically a quadrangular pyramid-shaped convex portion, and like the flat surface portion 21, it has a front view rhombus (a square inclined by 45 ° with respect to the length direction of the base material 1). ) Is formed. The convex portion 23 has a contour 24 on a reference plane.

The contour 24 is a line that defines the outer edge of the three-dimensional shape portion 22, and is only a valley line between adjacent convex portions 23, or a boundary line between the flat surface portion 21 and the convex portion 23 and adjacent convex portions. It is composed of a valley line between the portions 23, that is, an intersection line of a plurality of surfaces having different angles, and is composed of a line located on a reference surface. The contour 24 has a diamond shape, and each side is inclined by 45 ° or 135 ° with respect to the length direction of the base material 1. In the front view, the apex 251 of the convex portion 23 is located in the region surrounded by the contour 24.

The apex 251 is the farthest point on the convex portion 23 with respect to the reference plane, and is composed of one point on the normal line of the reference plane. In other words, the vertex 251 is composed of the end points 25 of the line segments that pass through the center of the figure formed by the contour 24 and are orthogonal to the reference plane. The apex 251 is located at the center (center of the figure) of the figure formed by the contour 24 in a plan view, and is located in front of the reference plane. Further, the height dimension of the apex 251 with respect to the reference plane (distance between the reference plane and the end point 25) is formed to be lower than the height dimension of the front surface of the planar convex portion 131 with respect to the reference plane, that is, the convex portion 23. Is formed lower than the planar convex portion 131, which is a region other than the first three-dimensional shape portion group 2. Further, all of the convex portions 23 in the first three-dimensional shape portion group 2 are formed to have the same height dimension.

The convex portion 23 has a plurality of inclined surfaces 261 (four in the present embodiment), and includes a side peripheral surface 26 composed of the plurality of inclined surfaces 261. The inclined surface 261 is a surface surrounded by a triangle connecting the points at both ends of one of the plurality of sides of the contour 24 and the three end points of the apex 251 and is inclined with respect to the reference surface. The inclined surface 261 is formed so as to correspond to all the sides of the contour 24, and the adjacent inclined surfaces 261 face each other in different directions.

The plurality of convex portions 23 having such a configuration are arranged side by side in a direction parallel to the side of the contour 24. The juxtaposed direction of the plurality of convex portions 23 is inclined by 45 ° with respect to the length direction of the base material 1, and the diagonal line of the contour 24 is parallel to one side of the base material 1. The adjacent convex portions 23 are adjacent to each other with one side of the contour 24 shared. The plurality of convex portions 23 and the flat surface portion 21 are arranged in a parallel direction of the plurality of convex portions 23, whereby the contour 24 forms a grid pattern in the entire first three-dimensional shape portion group 2.

As described above, the first three-dimensional shape portion group 2 is composed of a plurality of inclined surfaces 261 in which the three-dimensional shape portions 22 face each other in different directions. Therefore, when light is irradiated from a light source such as sunlight or illumination light in the state where the building board is installed, the shades appearing on each convex portion 23 have three or more stages. That is, a plurality of shades appear in the three-dimensional shape portion 22, such that the inclined surface 261 facing the light source becomes the brightest, and then the inclined surface 261 closest to the light source becomes the second brightest. Therefore, the expression by shadow becomes complicated, and it becomes possible to form a new design that has never existed before. At the same time, a shadow is also generated by the three-dimensional shape portion 22, so that a more complicated expression can be made.

FIGS. 1 and 2 show a state in which the building board is irradiated with light from the front and the upper left. The side peripheral surface of the convex portion 23 is located on the lower right side of the first inclined surface 261a located on the upper left side, the second inclined surface 261b located on the lower left side, and the third inclined surface 261c located on the upper right side. It is composed of a fourth inclined surface 261d.

Since the first inclined surface 261a is inclined forward toward the lower right side, the angle between the normal direction and the incident direction of the light is the smallest, and the amount of light received is the largest. Therefore, the intensity of the reflected light is the highest, and as a result, the first inclined surface 261a is the brightest. Next, the angle between the normal direction and the incident direction of the light of the second inclined surface 261b and the third inclined surface 261c is the second smallest after the first inclined surface 261a, and as a result, the second inclined surface 261b and the third inclined surface 261b and the third inclined surface 261b. The inclined surface 261c becomes brighter next to the first inclined surface 261a. Finally, since the fourth inclined surface 261d is inclined forward toward the upper left side, the angle between the normal direction and the incident direction of the light is the largest, and the amount of light received is the smallest. Therefore, the intensity of the reflected light is the smallest, and as a result, the fourth inclined surface 261d is the darkest. From the above, these inclined surfaces 261a to 261d are discontinuously and gradually darkened in this order.

By regularly arranging the convex portions 23 that express the stepwise shadows in this way, the shadows having different densities are geometrically arranged, and a unified shadow pattern can be expressed.

Moreover, each convex portion 23 of the first three-dimensional shape portion group 2 is surrounded by the planar convex portion 131 and is formed lower than the planar convex portion 131. Therefore, it is possible to prevent the convex portion 23 from being chipped even when the building boards are stacked during transportation or storage.

Next, the second three-dimensional shape portion group 3 will be described. 3A and 3B show an enlarged view of the second three-dimensional shape portion group 3, and FIGS. 4A and 4B show a perspective view of a cross section taken along the line AB in FIG. Here, FIG. 3B is a diagram in which auxiliary lines are drawn in the portions corresponding to the contour 33 and the ridge line in FIG. 3A, and shading is drawn in the portions corresponding to the convex portions 32. Further, FIG. 4B is a diagram in which auxiliary lines are drawn in the portions corresponding to the contour 33 and the ridge line in FIG. 4A, and shading is drawn in the portions corresponding to the convex portions 32.

The second three-dimensional shape portion group 3 includes a plurality of convex portions 32 and a plurality of concave portions 36 as the plurality of three-dimensional shape portions 31. The plurality of convex portions 32 are formed side by side in the length direction of the base material 1. Further, the plurality of recesses 36 are also formed side by side in the length direction of the base material 1. The convex portions 32 and the concave portions 36 are formed so as to be alternately arranged in the width direction of the base material 1.

Similar to the first three-dimensional shape portion group 2, the convex portion 32 includes a contour 33, a vertex 341 (end point 34), and a side peripheral surface 35 composed of a plurality of inclined surfaces 351. The relationship between the contour 33 and the apex 341 is the same as that of the convex portion 23 of the first three-dimensional shape portion group 2.

As shown in FIG. 4, the convex portion 32 projects forward with respect to the reference plane, and is formed in a rectangular shape having a longitudinal direction in a direction parallel to the length direction of the base material 1 in a plan view. .. The convex portion 32 has a rectangular contour 33 on the reference plane. The contour 33 of the convex portion 32 is formed so that two parallel sides are parallel to one side of the base material 1. As shown in FIGS. 3A and 3B, the convex portion 32 has a vertex 341 located at the center of a figure formed by a rectangular contour 33, and is formed in a quadrangular pyramid shape.

As shown in FIG. 4, the recess 36 forms a space recessed rearward with respect to the reference plane. The concave portion 36 has the same contour 33 as the contour 33 of the convex portion 32, and the contour 33 is formed in a rectangular shape having a long side in a direction parallel to the length direction of the base material 1 (the concave portion 36 has the same contour 33 as the contour 33. That is, two parallel sides of the contour 33 of the recess 36 are parallel to one side of the base material 1). The lower end portion 371 of the recess 36 is the farthest point on the surface of the recess 36 with respect to the reference surface, and is composed of one point on the normal line of the reference surface passing through the center of the figure formed by the contour 33 of the recess 36. .. In other words, the lower end portion 371 of the recess 36 is composed of the end points 37 of a line segment that passes through the center of the figure formed by the contour 33 and is orthogonal to the reference plane. The lower end portion 371 of the recess 36 is located behind the reference plane.

The recess 36 has a plurality of inclined surfaces 381 (four in the present embodiment), and includes a side peripheral surface 38 composed of the plurality of inclined surfaces 381. The inclined surface 381 constituting the concave portion 36 is a triangular surface surrounded by a triangle connecting the points at both ends of one side of the plurality of sides of the contour 33 and the three points at the lower end portion 371, and is a reference surface. It is inclined with respect to. The inclined surface 381 is formed so as to correspond to all the sides of the contour 33, and the inclined surfaces 381 adjacent to each other in the horizontal direction face each other in different directions.

The convex portion 32 and the concave portion 36 are adjacent to each other in the width direction of the base material 1 in a state where one side of the contour 33 is shared. As shown in FIG. 4, the inclined surface 351 adjacent to the concave portion 36 of the plurality of inclined surfaces 351 of the convex portion 32 is the inclined surface 381 adjacent to the convex portion 32 of the plurality of inclined surfaces 381 of the concave portion 36. Is continuous. In particular, in the present embodiment, the inclined surface 351 of the convex portion 32 has substantially the same inclination angle with respect to the inclined surface 381 of the concave portion 36 adjacent to the inclined surface 351.

In addition, "continuous" here means that they are connected without a step, and the inclination angles of the inclined surface 351 of the convex portion 32 and the inclined surface 381 of the concave portion 36 do not necessarily have to be the same. ..

Here, FIG. 3A shows a state in which the building board is irradiated with light from the front and the upper left, as in FIGS. 1 and 2.

The side peripheral surface of the convex portion 32 includes a first inclined surface 351a located on the upper side, a second inclined surface 351b and a third inclined surface 351c located on both left and right sides, and a fourth inclined surface 351d located on the lower side. It is composed of. Since the first inclined surface 351a is inclined forward toward the lower side, the angle formed by the normal direction and the incident direction of the light is the smallest, and the light receiving amount is the largest. Therefore, the intensity of the reflected light is the highest, and as a result, the first inclined surface 351a is the brightest. Next, in the second inclined surface 351b and the third inclined surface 351c, the angle formed by each normal direction and the incident direction of light is the second smallest after the first inclined surface 351a, and as a result, the second inclined surface 351b and the second inclined surface 351b. 3 The inclined surface 351c becomes brighter next to the first inclined surface 351a. Since the second inclined surface 351b and the third inclined surface 351c have different inclination angles, the shade density is slightly different. Finally, since the fourth inclined surface 351d is inclined forward toward the upper side, the angle between the normal direction and the incident direction of the light is the largest, and the amount of light received is the smallest. Therefore, the intensity of the reflected light is the smallest, and as a result, the fourth inclined surface 351d is the darkest. From the above, the inclined surfaces 351a to 351d are discontinuously and gradually darkened in this order.

The side peripheral surface of the recess 36 is formed by a first inclined surface 381a located on the lower side, a second inclined surface 381b and a third inclined surface 381c located on both left and right sides, and a fourth inclined surface 381d located on the upper side. It is configured. Since the first inclined surface 381a is inclined forward toward the lower side, the angle between the normal direction and the incident direction of the light is the smallest, and the amount of light received is the largest. Therefore, the intensity of the reflected light is the highest, and as a result, the first inclined surface 381a is the brightest. Next, in the second inclined surface 381b and the third inclined surface 381c, the angle formed by each normal direction and the incident direction of light is the second smallest after the first inclined surface 381a, and as a result, the second inclined surface 381b and the second inclined surface 381b. 3 The inclined surface 381c becomes brighter next to the first inclined surface 381a. Since the second inclined surface 381b and the third inclined surface 381c have different inclination angles, the shade density is slightly different. Finally, since the fourth inclined surface 381d is inclined forward toward the upper side, the angle between the normal direction and the incident direction of the light is the largest, and the amount of light received is the smallest. Therefore, the intensity of the reflected light is the lowest, and as a result, the fourth inclined surface 381d is the darkest. From the above, these inclined surfaces 381a to 381d are discontinuously and gradually darkened in this order.

The concave portions 36 are provided on both the upper and lower sides of the convex portion 32, and the brightest first inclined surface 381a of the concave portion 36 is continuously adjacent to the upper side of the brightest first inclined surface 351a of the convex portion 32. The darkest fourth inclined surface 381d of the recess 36 is continuously adjacent to the lower side of the darkest fourth inclined surface 351d. The first inclined surface 351a and the first inclined surface 381a form the same isosceles triangle shape and share a long side. Therefore, these two surfaces form the brightest rhombus. Similarly, the fourth inclined surface 351d and the fourth inclined surface 381d form the same isosceles triangle shape and share a long side. Therefore, these two surfaces form the darkest rhombus.

On the other hand, the convex portions 32 are arranged in the left-right direction, and the second inclined surface 351b and the third inclined surface 351c are adjacent to each other. As described above, the inclined surfaces 351b and 351c are recognized so that the faces of the isosceles triangles are arranged side by side because the shades are slightly different. Similarly, the recesses 36 are also arranged in the left-right direction, and it is recognized that the faces of the isosceles triangle formed by the second inclined surface 381b and the third inclined surface 381c are arranged side by side.

As described above, in the second three-dimensional shape portion group 3, as in the first three-dimensional shape portion group 2, each three-dimensional shape portion 31 is composed of a plurality of inclined surfaces 351 and 381 having different angles (angles with respect to the reference plane). Therefore, it is possible to make various expressions by shading. In particular, in the second three-dimensional shape portion group 3, since the adjacent inclined surfaces 351 and 381 of the convex portion 32 and the concave portion 36 are continuous, this portion is recognized by the viewer as a rhombic surface. Will be done. Therefore, in the second three-dimensional shape portion group 3, as shown in FIG. 3, a large number of triangular surfaces having different shades appear, and the triangular surface and the diamond-shaped surface are recognized as a mixture. Therefore, even though it is a simple shape, it can be recognized as a complicated shape by the viewer.

[Embodiment 2]
Next, the second embodiment will be described with reference to FIGS. 5A and 5B. Since this embodiment is almost the same as that of the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted, and different parts will be mainly described.

A row (referred to as a concave-convex row 6) in which a convex portion 41 and a concave portion 42 are repeatedly formed is adjacent to the convex portion row 5. The uneven row 6 is adjacent to the convex portion 41 and the concave portion 42 in a state where one side of the contour 43 is shared. The concavo-convex row 6 is inclined by 45 ° with respect to the length direction of the base material 1, and the concavo-convex row 5 is formed adjacent to the concavo-convex row 6 in a direction orthogonal to the length direction of the concavo-convex row 6 and along the reference plane. There is.

As described above, the building board of the present embodiment has a quadrangular pyramid-shaped convex portion 41 and a quadrangular pyramid-shaped concave portion 42 as the three-dimensional shape portion 4, as in the case of the building board of the first embodiment. The arrangement of the convex portion 41 and the concave portion 42 is different from that of the building board of the first embodiment.

According to this, it is possible to make the viewer recognize the design as different from the building board of the first embodiment only by changing the arrangement of the convex portion 41 and the concave portion 42. As a result, various design variations can be formed.
