以下、本発明の一実施形態について添付図面に基づいて説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

〔実施形態１〕
本実施形態の建築板は、図１に示すように、外壁材であり、例えば、窯業系サイディング材により構成されている。本実施形態の建築板は、横張り（横長状態での設置）および縦張り（縦長状態での設置）のいずれにも対応可能であるが、以下においては、横張りされた状態に基づいて説明する。したがって、上下方向に平行な方向を幅方向とし、左右方向に平行な方向を長さ方向として定義し、幅方向および長さ方向に直交する方向を前後方向として定義する。また、建築板において前後方向に直交する平面を主面という場合がある。なお、図１等の基材１の表面に表れる濃淡は、塗装により塗り分けられたものではなく、表面に表れた陰影によるものである。 [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.

建築板は、基材１により主体が構成されている。基材１は、塗装される前の成形体であり、例えば、窯業系の基材により構成される。基材１の表面には、図１に示すように、幅方向に延びた疑似目地（以下、縦目地１１）と、長さ方向に延びた疑似目地（以下、横目地１２）とにより区画された複数の矩形状凸部１３が形成されている。これら複数の矩形状凸部１３と目地１１，１２とは、例えば、プレス金型を用いて、基材１の表面に凹凸形状を形成することで構成されている。 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.

本実施形態の建築板は、複数の矩形状凸部１３として、平面状凸部１３１と、立体形状部群１３２とを備えている。平面状凸部１３１は、前面が平坦に形成されている。立体形状部群１３２は、前面に複数の立体形状部２２，３１が集合して構成されている。本実施形態の建築板は、立体形状部群１３２として、２種類の立体形状部群１３２（第１の立体形状部群２，第２の立体形状部群３とする）を備えている。 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.

図２には第１の立体形状部群２の拡大図を示す。第１の立体形状部群２は、複数の平面部２１と複数の立体形状部２２とを備えている。これら平面部２１と立体形状部２２とは、基準面を基準に形成されている。ここで、基準面は、前後方向に直交する平面状の仮想面であり、本実施形態では、平面状凸部１３１の前面よりも後方で、かつ目地１１，１２の底面よりも前方の位置に規定されている。 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.

平面部２１は、基準面と高さが一致し且つ基準面に平行な平坦面により構成されており、基準面に正対する方向にみて（以下、正面視という）ひし形（基材１の長さ方向に対し４５°傾いた正方形、言い換えると、一の対角線が基材１の長さ方向に平行な正方形）に形成されている。また、平面部２１は、基準面に対して、同一平面上に位置している。平面部２１は、第１の立体形状部群２の上下方向の中央部に配置されており、左右方向（基材１の長さ方向）に並んで複数配置されている。すなわち、平面部２１は、第１の立体形状部群２の領域内に形成されている。 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.

立体形状部２２は、基準面上に立体的に形成された形状をなす部分である。第１の立体形状部群２における立体形状部２２は、基準面から前方に突出した角錐状の凸部２３により構成されている。本実施形態の角錐状の凸部２３は、具体的には四角錐状の凸部であり、平面部２１と同様に、正面視ひし形（基材１の長さ方向に対し４５°傾いた正方形）に形成されている。この凸部２３は、基準面上に輪郭２４を有している。 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.

輪郭２４は、立体形状部２２の外縁を規定する線であり、隣接する凸部２３同士の間の谷線のみ、あるいは、平面部２１と凸部２３との間の境界線と、隣接する凸部２３同士の間の谷線とで構成されており、つまり、角度の異なる複数の面の交線であって、基準面上に位置する線により構成されている。輪郭２４は、ひし形をなしており、各辺が基材１の長さ方向に対して４５°または１３５°傾斜している。正面視において、輪郭２４に囲まれた領域には、凸部２３の頂点２５１が位置している。 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.

頂点２５１は、基準面に対して凸部２３上の最も離れた点であり、基準面の法線上の一点により構成される。言い換えると、頂点２５１は、輪郭２４が形成する図形の中心を通り且つ基準面に直交する線分の端点２５により構成される。頂点２５１は、平面視において、輪郭２４により形成される図形の中心（図心）に位置し、且つ、基準面の前方に位置している。また、基準面に対する頂点２５１の高さ寸法（基準面と端点２５との距離）は、基準面に対する平面状凸部１３１の前面の高さ寸法よりも低く形成されており、すなわち、凸部２３は、第１の立体形状部群２以外の領域である平面状凸部１３１よりも低く形成されている。さらに、第１の立体形状部群２における凸部２３は、すべてが同じ高さ寸法に形成されている。 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.

凸部２３は、複数の傾斜面２６１を有しており（本実施形態では４つ）、該複数の傾斜面２６１により構成された側周面２６を備えている。傾斜面２６１は、輪郭２４の複数の辺のうちの一辺の両端の点と、頂点２５１との３つの端点を結ぶ三角形で囲まれた面であり、基準面に対して傾斜している。傾斜面２６１は、輪郭２４のすべての辺に対応して形成されており、隣り合う傾斜面２６１同士が互いに異なる方向に臨んでいる。 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.

このような構成の複数の凸部２３は、輪郭２４の辺に平行な方向に並設されている。この複数の凸部２３の並設方向は、基材１の長さ方向に対して４５°傾いており、輪郭２４の対角線が基材１の一辺と平行である。隣り合う凸部２３同士は、輪郭２４の一辺を共有した状態で隣接している。複数の凸部２３と平面部２１とは、複数の凸部２３の並設方向に並んでおり、これにより、第１の立体形状部群２全体では、輪郭２４が格子状をなしている。 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.

このように第１の立体形状部群２は、各立体形状部２２が、互いに異なる方向に臨む複数の傾斜面２６１により構成されている。このため、建築板を設置した状態において、太陽光や照明光等の光源から光が照射されると、各凸部２３に現れる陰の濃淡が、３段階以上となる。つまり、光源に臨む傾斜面２６１が最も明るくなり、次に光源に近い傾斜面２６１が２番目に明るくなる、というように、立体形状部２２に複数の濃淡が現れる。したがって、陰による表現が複雑になり、従来にない新たなデザインを形成することが可能となる。それに併せて、立体形状部２２により影も生じるため、より複雑な表現をすることができる。 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.

図１，２は、建築板に前方且つ左上から光が照射された状態を示している。凸部２３の側周面は、左上に位置する第１傾斜面２６１ａと、左下側に位置する第２傾斜面２６１ｂと、右上側に位置する第３傾斜面２６１ｃと、右下側に位置する第４傾斜面２６１ｄと、によって構成されている。 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.

そして、第１傾斜面２６１ａは、右下側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も小さく、その受光量が最も大きくなる。したがって、反射光の強度が最も大きくなり、結果として、第１傾斜面２６１ａが最も明るくなる。次いで、第２傾斜面２６１ｂ及び第３傾斜面２６１ｃは、各法線方向と光の入射方向とのなす角度が第１傾斜面２６１ａの次に小さく、結果として、第２傾斜面２６１ｂ及び第３傾斜面２６１ｃが第１傾斜面２６１ａの次に明るくなる。最後に、第４傾斜面２６１ｄは、左上側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も大きく、その受光量が最も小さくなる。したがって、反射光の強度が最も小さくなり、結果として、第４傾斜面２６１ｄが最も暗くなる。以上より、これら傾斜面２６１ａ〜２６１ｄは、この順番に不連続且つ段階的に陰が濃くなる。 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.

そして、このように段階的な陰影を表現する凸部２３が規則正しく並ぶことにより、濃度の異なる陰影が幾何学的に配列され、統一感のある陰影模様を表現することができる。 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.

しかも、第１の立体形状部群２の各凸部２３は、平面状凸部１３１に囲まれている上に、平面状凸部１３１よりも低く形成されている。このため、運搬時や保管時等に、建築板を重ねても、凸部２３が欠けてしまうのを抑制することができる。 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.

次に、第２の立体形状部群３について説明する。図３Ａ，３Ｂには第２の立体形状部群３の拡大図を示し、図４Ａ，４Ｂには、図３におけるＡ−Ｂ線断面の斜視図を示す。ここで、図３Ｂは、図３Ａにおいて輪郭３３や稜線に相当する箇所に補助線を記入し、凸部３２に相当する箇所に網掛けを記入した図である。また、図４Ｂは、図４Ａにおいて輪郭３３や稜線に相当する箇所に補助線を記入し、凸部３２に相当する箇所に網掛けを記入した図である。 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.

第２の立体形状部群３は、複数の立体形状部３１として、複数の凸部３２と、複数の凹部３６とを備えている。複数の凸部３２は、基材１の長さ方向に並んで形成されている。また、複数の凹部３６も、基材１の長さ方向に並んで形成されている。凸部３２と凹部３６とは、基材１の幅方向に交互に並んで形成されている。 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.

凸部３２は、第１の立体形状部群２と同様、輪郭３３と、頂点３４１（端点３４）と、複数の傾斜面３５１からなる側周面３５とを備えている。輪郭３３と頂点３４１との関係は、第１の立体形状部群２の凸部２３と同じである。 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.

凸部３２は、図４に示すように、基準面に対して前方に突出しており、平面視において、基材１の長さ方向に平行な方向に長手方向を有する長方形状に形成されている。凸部３２は、基準面上に、矩形状の輪郭３３を有している。凸部３２の輪郭３３は、平行な二辺が基材１の一辺と平行となるように形成されている。凸部３２は、図３Ａ，Ｂに示すように、頂点３４１が長方形状の輪郭３３により形成される図形の中心に位置しており、四角錐状に形成されている。 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.

凹部３６は、図４に示すように、基準面に対して後方に凹んだ空間を形成する。凹部３６は、凸部３２の輪郭３３と同一の輪郭３３を有しており、該輪郭３３は、基材１の長さ方向に平行な方向を長辺とする矩形状に形成されている（つまり、凹部３６の輪郭３３のうちの平行な二辺は基材１の一辺に平行である）。凹部３６の下端部３７１は、基準面に対して凹部３６の表面の最も離れた点であり、凹部３６の輪郭３３により形成される図形の中心を通る基準面の法線上の一点により構成される。言い換えると、凹部３６の下端部３７１は、輪郭３３が形成する図形の中心を通りかつ基準面に直交する線分の端点３７により構成される。凹部３６の下端部３７１は、基準面の後方に位置している。 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.

凹部３６は、複数の傾斜面３８１を有しており（本実施形態では４つ）、該複数の傾斜面３８１により構成された側周面３８を備えている。凹部３６を構成する傾斜面３８１は、輪郭３３の複数の辺のうちの一辺の両端の点と、下端部３７１との３つの点を結ぶ三角形で囲まれた三角形状の面であり、基準面に対して傾斜している。傾斜面３８１は、輪郭３３のすべての辺に対応して形成されており、水平方向に隣り合う傾斜面３８１同士が互いに異なる方向に臨んでいる。 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.

凸部３２と凹部３６は、輪郭３３の一辺を共有した状態で、基材１の幅方向に隣接している。図４に示すように、凸部３２の複数の傾斜面３５１のうちの凹部３６に隣接する傾斜面３５１は、凹部３６の複数の傾斜面３８１のうちの当該凸部３２に隣接する傾斜面３８１と連続している。とりわけ、本実施形態において、凸部３２の傾斜面３５１は、当該傾斜面３５１に隣接する凹部３６の傾斜面３８１に対し、略同一の傾斜角度を有している。 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.

なお、ここでいう「連続」とは、段差無く接続されていることを意味しており、凸部３２の傾斜面３５１と凹部３６の傾斜面３８１との傾斜角度は必ずしも同一である必要はない。 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. ..

ここで、図３Ａは、図１，２と同様に、建築板に前方且つ左上から光が照射された状態を示している。 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.

凸部３２の側周面は、上側に位置する第１傾斜面３５１ａと、左右両側に位置する第２傾斜面３５１ｂ及び第３傾斜面３５１ｃと、下側に位置する第４傾斜面３５１ｄと、によって構成されている。第１傾斜面３５１ａは、下側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も小さく、受光量が最も大きくなる。したがって、反射光の強度が最も大きくなり、結果として、第１傾斜面３５１ａが最も明るくなる。次に、第２傾斜面３５１ｂ及び第３傾斜面３５１ｃは、各法線方向と光の入射方向とのなす角度が第１傾斜面３５１ａの次に小さく、結果として、第２傾斜面３５１ｂ及び第３傾斜面３５１ｃが第１傾斜面３５１ａの次に明るくなる。なお、これら第２傾斜面３５１ｂ及び第３傾斜面３５１ｃは、傾斜角度が異なるため、陰の濃さが若干異なる。最後に、第４傾斜面３５１ｄは、上側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も大きく、その受光量が最も小さくなる。したがって、反射光の強度が最も小さくなり、結果として、第４傾斜面３５１ｄが最も暗くなる。以上より、これら傾斜面３５１ａ〜３５１ｄは、この順番に不連続且つ段階的に陰が濃くなる。 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.

凹部３６の側周面は、下側に位置する第１傾斜面３８１ａと、左右両側に位置する第２傾斜面３８１ｂ及び第３傾斜面３８１ｃと、上側に位置する第４傾斜面３８１ｄと、によって構成されている。第１傾斜面３８１ａは、下側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も小さく、受光量が最も大きくなる。したがって、反射光の強度が最も大きくなり、結果として、第１傾斜面３８１ａが最も明るくなる。次に、第２傾斜面３８１ｂ及び第３傾斜面３８１ｃは、各法線方向と光の入射方向とのなす角度が第１傾斜面３８１ａの次に小さく、結果として、第２傾斜面３８１ｂ及び第３傾斜面３８１ｃが第１傾斜面３８１ａの次に明るくなる。なお、これら第２傾斜面３８１ｂ及び第３傾斜面３８１ｃは、傾斜角度が異なるため、陰の濃さが若干異なる。最後に、第４傾斜面３８１ｄは、上側に向かって前方に傾斜しているため、その法線方向と光の入射方向とのなす角度が最も大きく、その受光量が最も小さくなる。したがって、反射光の強度が最も小さくなり、結果として、第４傾斜面３８１ｄが最も暗くなる。以上より、これら傾斜面３８１ａ〜３８１ｄは、この順番に不連続且つ段階的に陰が濃くなる。 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.

そして、凸部３２の上下両側に凹部３６が設けられ、凸部３２の最も明るい第１傾斜面３５１ａの上側に凹部３６の最も明るい第１傾斜面３８１ａが連続して隣接し、凸部３２の最も暗い第４傾斜面３５１ｄの下側に凹部３６の最も暗い第４傾斜面３８１ｄが連続して隣接している。第１傾斜面３５１ａ及び第１傾斜面３８１ａは同一の二等辺三角形状をなし、長辺を共有している。したがって、これら２面により、最も明るいひし形が形成される。また、同様に、第４傾斜面３５１ｄ及び第４傾斜面３８１ｄは同一の二等辺三角形状をなし、長辺を共有している。したがって、これら２面により、最も陰の濃いひし形が形成される。 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.

一方、凸部３２は左右方向に並べられており、第２傾斜面３５１ｂと第３傾斜面３５１ｃとが隣り合っている。そして、これら傾斜面３５１ｂ，３５１ｃは、上記の如く、陰の濃さが若干異なるため、二等辺三角形の面が左右に並ぶように認識される。同様に、凹部３６も左右方向に並べられており、第２傾斜面３８１ｂ及び第３傾斜面３８１ｃによって形成される二等辺三角形の面が左右に並ぶように認識される。 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.

このように第２の立体形状部群３も、第１の立体形状部群２と同様、各立体形状部３１が、互いに異なる角度（基準面に対する角度）の複数の傾斜面３５１，３８１により構成されているため、陰の濃淡による表現を多様にすることができる。特に、第２の立体形状部群３は、凸部３２と凹部３６との隣り合う傾斜面３５１，３８１が連続しているため、この部分について、看者に対して、ひし形状の面として認識されることになる。したがって、第２の立体形状部群３は、図３に示すように、濃淡の異なる三角状の面が多数現れる上に、三角状の面と、ひし形状の面とが混在して認識され、したがって、単純な形状であるにもかかわらず、看者に対し複雑な形状として認識させることができる。 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.

〔実施形態２〕
次に、実施形態２について図５Ａ，Ｂに基づいて説明する。なお、本実施形態は、実施形態１と大部分において同じであるため、同じ部分においては同符号を付して説明を省略し、主に異なる部分について説明する。 [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.

本実施形態の建築板は、図５Ａ，Ｂに示す立体形状部群１３２が基材１の表面の一部に形成された建築板である。この立体形状部群１３２は、１つの基材１に対して複数箇所に形成されている。本実施形態の建築板は、実施形態１と同様、窯業系の基材により構成されている。なお、図５Ｂには、図５Ａに対して輪郭４３および稜線を示す補助線と、凸部４１に相当する箇所に網掛けを記入した図を示す。 The building board of the present embodiment is a building board in which the three-dimensional shape portion group 132 shown in FIGS. 5A and 5B is formed on a part of the surface of the base material 1. The three-dimensional shape portion group 132 is formed at a plurality of locations with respect to one base material 1. The building board of the present embodiment is composed of a ceramic-based base material as in the first embodiment. Note that FIG. 5B shows an auxiliary line showing the contour 43 and the ridge line with respect to FIG. 5A, and a diagram in which the portion corresponding to the convex portion 41 is shaded.

立体形状部群１３２は、複数の凸部４１と、複数の凹部４２とを備えている。凸部４１の輪郭４３、および、凹部４２の輪郭４３は、いずれも、ひし形状に形成されており、輪郭４３の対角線が基材１の一辺と平行である。立体形状部群１３２全体に形成される輪郭４３は格子状をなしている。 The three-dimensional shape portion group 132 includes a plurality of convex portions 41 and a plurality of concave portions 42. The contour 43 of the convex portion 41 and the contour 43 of the concave portion 42 are both formed in a rhombus shape, and the diagonal line of the contour 43 is parallel to one side of the base material 1. The contour 43 formed on the entire three-dimensional shape portion group 132 has a grid pattern.

複数の凸部４１は、隣り合った状態で並設されている（この列を凸部列５という）。この凸部列５の並設方向は、基材１の長さ方向に対して４５°傾いている。凸部列５には、凸部４１と凹部４２とが繰り返し形成された列（凹凸列６という）が隣接している。この凹凸列６は、凸部４１と凹部４２とが輪郭４３の一辺を共有した状態で隣接している。凹凸列６は、基材１の長さ方向に対して４５°傾いており、凹凸列６の長さ方向に直交し且つ基準面に沿う方向に、凸部列５が隣接して形成されている。 The plurality of convex portions 41 are arranged side by side in an adjacent state (this row is referred to as a convex portion row 5). The juxtaposed direction of the convex portions 5 is inclined by 45 ° with respect to the length direction of the base material 1. 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.

このように、本実施形態の建築板は、実施形態１の建築板と同じように、立体形状部４として、四角錐状の凸部４１と、四角錐状の凹部４２とを備えているが、凸部４１と凹部４２の配置を、実施形態１の建築板とは異ならせている。 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.

これによれば、凸部４１と凹部４２との配置を異ならせるだけで、看者に対し、実施形態１の建築板とは別異のデザインとして認識させることができる。この結果、デザインバリエーションを多様に形成することができる。 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.

〔効果〕
以上、説明したように、上記実施形態１，２の建築板は、基材１の表面に複数の立体形状部４，２２，３１が集合してなる立体形状部群１３２が形成された建築板である。各立体形状部４，２２，３１は、基材１の表面に規定された基準面上に位置する多角形状の輪郭２４，３３，４３と、輪郭２４，３３，４３に囲まれた領域内における基準面の法線上で、かつ基準面とは異なる高さに位置する一つの端点２５，３４，３７と、側周面２６，３５，３８とを備えている。側周面２６，３５，３８は、輪郭２４，３３，４３の一辺の両端の点と、前記一点（端点２５，３４，３７）との３つの点を結ぶ三角形で囲まれた面（傾斜面２６１，３５１，３８１）を複数有しており、この複数の面（傾斜面２６１，３５１，３８１）が輪郭２４，３３，４３を構成する複数の辺に対応して設けられている。 〔effect〕
