FIG. 1 is a front view when a building board is installed as an outer wall material, for example. FIG. 2A is an enlarged front view of a part of FIG. The building board according to the present invention is formed by arranging a plurality of rectangular convex portions 1 so as to be adjacent to each other vertically and horizontally. The building board is formed by arranging a plurality of convex portions 1 adjacent to each other right and left through vertical joint portions 5 and adjacent to each other vertically via horizontal joint portions 6. The vertical joint portion 5 and the horizontal joint portion 6 may adopt normal joint shapes such as a box joint having a substantially inverted trapezoidal cross section and a butted V joint. The vertical joint 5 and the horizontal joint 6 can be formed flush.

凸部1は、対向する一対の端部に向かって下り傾斜する斜面2を有する。すなわち、凸部1の左側の端部に向かって傾斜している左斜面2a及び右側の端部に向かって傾斜している右斜面2bを有する。本明細書では、左斜面2a及び右斜面2bを、斜面2ということもある。左斜面2a及び右斜面2bのうち少なくとも一方に、陰影形成構造40が設けられている。陰影形成構造40とは、当該構造に光が当たった場合に影を形成することができるような構造(形状)を意味する。   The convex part 1 has the slope 2 which inclines down toward a pair of opposing edge part. That is, it has the left slope 2a inclined toward the left end of the convex portion 1 and the right slope 2b inclined toward the right end. In the present specification, the left slope 2a and the right slope 2b are sometimes referred to as the slope 2. A shadow forming structure 40 is provided on at least one of the left slope 2a and the right slope 2b. The shadow forming structure 40 means a structure (shape) that can form a shadow when light strikes the structure.

建築板の形状は、略矩形状であってよい。建築板の大きさは特に限定されないが、例えば、左右方向の長さが0.5〜3.5m、上下方向の長さが0.3〜1.0m、厚みが0.6〜6cmである。   The shape of the building board may be a substantially rectangular shape. Although the magnitude | size of a building board is not specifically limited, For example, the length of the left-right direction is 0.5-3.5 m, the length of an up-down direction is 0.3-1.0 m, and thickness is 0.6-6 cm. .

正面視において、凸部1の大きさは、特に限定されないが、例えば、横が2.5〜50cm、縦が1.0〜20cmである。また、凸部1の高さは高ければ高いほど好ましいが、一般的な建築板の厚みを考慮すると、例えば、2〜10mm程度にすることができる。凸部1の高さとは、建築板の厚み方向において、縦目地部5又は横目地部6からの突出高さを意味する。なお、本明細書では、建築板を施工した際に、正面視においての建築板の左右方向を凸部1の左右方向、建築板の上下方向を凸部1の上下方向という。   Although the magnitude | size of the convex part 1 is not specifically limited in front view, For example, width is 2.5-50 cm and length is 1.0-20 cm. Moreover, although the height of the convex part 1 is so preferable that it is high, when the thickness of a general building board is considered, it can be made into about 2-10 mm, for example. The height of the convex part 1 means the protrusion height from the vertical joint part 5 or the horizontal joint part 6 in the thickness direction of a building board. In addition, in this specification, when constructing a building board, the left-right direction of the building board in front view is called the left-right direction of the convex part 1, and the up-down direction of a building board is called the up-down direction of the convex part 1.

図2(b)(c)、図3(a)(b)のように、凸部1は、上面7、下面8、上面7と下面8の間の頂部3、左斜面2a、右斜面2bとを有する。左斜面2aは頂部3から左側に向かって傾斜し、右斜面2bは頂部3から右側に向かって傾斜している。   As shown in FIGS. 2B and 2C and FIGS. 3A and 3B, the convex portion 1 has an upper surface 7, a lower surface 8, a top portion 3 between the upper surface 7 and the lower surface 8, a left inclined surface 2a, and a right inclined surface 2b. And have. The left slope 2a is inclined from the top 3 toward the left side, and the right slope 2b is inclined from the top 3 toward the right side.

凸部1において、頂部3、左斜面2a、右斜面2bのそれぞれの横の長さ比率は適宜設定され、例えば、1:1〜3:1程度である。凸部1の左右方向における頂部3の中心位置は、適宜設定され、図3(a)(b)のように凸部1の中心位置と一致していてもよく、凸部1の中心位置から左右にずれていてもよい。   In the convex part 1, each horizontal length ratio of the top part 3, the left slope 2a, and the right slope 2b is appropriately set, and is, for example, about 1: 1 to 3: 1. The center position of the top part 3 in the left-right direction of the convex part 1 is appropriately set and may coincide with the central position of the convex part 1 as shown in FIGS. It may be shifted from side to side.

凸部1の上面7及び下面8は、平面に形成することができる。また、凸部1の上面7は、水平に形成されていてもよく、図2(c)のように、上面7は、傾斜していてもよい。凸部1の下面8は、水平に形成されていてもよく、図2(c)のように、傾斜していてもよい。   The upper surface 7 and the lower surface 8 of the convex part 1 can be formed in a plane. Moreover, the upper surface 7 of the convex part 1 may be formed horizontally, and the upper surface 7 may be inclined like FIG.2 (c). The lower surface 8 of the convex portion 1 may be formed horizontally, or may be inclined as shown in FIG.

図3(a)(b)のように、凸部1は、頂部3、左斜面2a、右斜面2bとが平面で形成され、上下方向から見た断面の形状が、略台形であってもよい。また、図2(b)のように、頂部3、左斜面2a、右斜面2bが、曲面で形成されていてもよい。頂部3、左斜面2a、右斜面2bとの間は、角を有していてもよく、角を有さずに滑らかにつながっていてもよい。滑らかにつながっているとは、曲線で形成される波状であることを意味する。また、左右に隣り合う凸部1の間の縦目地部5は、滑らかな曲線で形成される曲面であってよく、平面であってもよい。   As shown in FIGS. 3 (a) and 3 (b), the convex portion 1 has a top portion 3, a left slope surface 2a, and a right slope surface 2b formed in a plane, and the cross-sectional shape viewed from the vertical direction is substantially trapezoidal. Good. Further, as shown in FIG. 2B, the top 3, the left slope 2a, and the right slope 2b may be formed as curved surfaces. The apex 3, the left slope 2a, and the right slope 2b may have corners or may be smoothly connected without having corners. “Smoothly connected” means a wave shape formed by a curve. Further, the vertical joint 5 between the left and right convex portions 1 may be a curved surface formed by a smooth curve, or may be a flat surface.

凸部1には、左斜面2a及び右斜面2bのうち少なくとも一方に、陰影形成構造40が設けられている。光が陰影形成構造40に当たり、影が形成されることにより、観る人に凸部1がより突出しているように視認させることができ、立体感を強調することができる。また、観察者が建築板を観る角度、光の差し込む角度、太陽の高度、季節による日差しの強さなどの変化により、陰影形成構造40の影が形成される位置や、陰影の濃さなどが変化する。これらは塗装では表現しきれない変化であり、陰影形成構造40によって意匠性を向上させることができる。   The projection 1 is provided with a shadow forming structure 40 on at least one of the left slope 2a and the right slope 2b. When the light hits the shadow forming structure 40 and a shadow is formed, it is possible to make the viewer visually recognize that the convex portion 1 protrudes more and enhance the stereoscopic effect. In addition, the position at which the shadow of the shadow forming structure 40 is formed, the density of the shadow, etc., due to changes in the angle at which the observer views the building board, the angle at which the light is inserted, the altitude of the sun, the intensity of the sun depending on the season, etc. Change. These are changes that cannot be expressed by painting, and the design can be improved by the shadow forming structure 40.

陰影形成構造40は、斜面2の少なくとも下部領域に設けられていることが好ましく、少なくとも端部付近に設けられていることがさらに好ましい。陰影形成構造40は、斜面2の上部領域にも設けられていてよい。なお、斜面2の中心付近から頂部3側を上部、斜面2の中心付近から端部側を下部という。   The shadow forming structure 40 is preferably provided at least in the lower region of the slope 2, and more preferably provided at least near the end. The shadow forming structure 40 may be provided also in the upper region of the slope 2. The top 3 side from the vicinity of the center of the slope 2 is referred to as the upper part, and the end side from the vicinity of the center of the slope 2 is referred to as the lower part.

陰影形成構造40としては、突起部、溝部、細かなシボなどを採用することができ、これらのうち1種類のみを用いてもよく、2種類以上を組み合わせてもよい。陰影形成構造40は、陰影形成構造40によって形成される陰影が、凸部1の中央部側から端部側に向かって濃くなるように設けられることが好ましい。これにより、観る人に凸部1がより突出しているように視認させることができ、より立体感を強調することができる。   As the shadow forming structure 40, a protrusion, a groove, a fine grain, or the like can be adopted, and only one type of these may be used, or two or more types may be combined. It is preferable that the shadow forming structure 40 is provided so that the shadow formed by the shadow forming structure 40 becomes darker from the center side to the end side of the convex portion 1. Thereby, it can be made to visually recognize so that the convex part 1 may protrude more, and a three-dimensional effect can be emphasized more.

陰影形成構造40を用いて、凸部1の中央部側から端部側に向かって陰影を濃くする方法としては、例えば、陰影形成構造40の配設密度を、凸部1の中央部側から端部側に向かって、高くする方法が挙げられる。また、陰影形成構造40が、突起部4である場合は、陰影形成構造40の突出高さを、凸部1の中央部側から端部側に向かって、だんだん高くする方法でもよい。また、陰影形成構造40が溝部である場合は、凸部1の中央部側から端部側に向かって、陰影形成構造40の溝深さをだんだん深くしたり、溝部の幅をだんだん広くしていく方法でもよい。また、陰影形成構造40が突起部4と細かなシボとの組み合わせの場合は、斜面2の上部領域に細かなシボを設け、斜面2の下部領域に突起部4を設ける方法でもよい。   As a method of using the shadow forming structure 40 to darken the shadow from the central portion side to the end portion side of the convex portion 1, for example, the arrangement density of the shadow forming structure 40 is changed from the central portion side of the convex portion 1. There is a method of increasing the height toward the end side. Moreover, when the shadow formation structure 40 is the protrusion part 4, the method of making the protrusion height of the shadow formation structure 40 gradually high toward the edge part side from the center part side of the convex part 1 may be used. Further, when the shadow forming structure 40 is a groove portion, the groove depth of the shadow forming structure 40 is gradually increased from the central portion side to the end portion side of the convex portion 1 or the width of the groove portion is gradually increased. You can use any method. Further, when the shadow forming structure 40 is a combination of the protrusion 4 and fine wrinkles, a method of providing fine wrinkles in the upper area of the slope 2 and providing the protrusion 4 in the lower area of the slope 2 may be used.

陰影形成構造40としては、突起部4を用いることが好ましく、突起部4であれば、より陰影を形成しやすくなる。図1〜図4では、突起部4のみを用いた陰影形成構造40が設けられた凸部1を有する建築板について説明するが、陰影形成構造40はこの構造に限定されない。   As the shadow forming structure 40, it is preferable to use the protruding portion 4, and the protruding portion 4 makes it easier to form a shadow. 1-4, the building board which has the convex part 1 in which the shadow formation structure 40 using only the projection part 4 was provided is demonstrated, but the shadow formation structure 40 is not limited to this structure.

図3(a)のように、突起部4は、左斜面2a及び右斜面2bの両方に設けられていることが好ましい。これにより、建築板に光が当たると、突起部4によって斜面2に影が形成され、観る人に凸部1がより突出しているように視認させることができ、立体感を強調することができる。また、頂部3と斜面2の縦の長さが同じ凸部1であっても、突起部4の影によって、頂部3の縦の長さよりも斜面2の縦の長さが長くなっているように錯覚させることもでき、凸部1がより突出しているように視認させることができ、立体感を強調することができる。突起部4は、左斜面2aにのみ設けられていてもよく、図3(b)のように右斜面2bにのみ設けられていてもよい。隣り合う凸部1の間に形成される凹部において、左右の斜面2の少なくとも一方に、複数の突起部4が設けられていることが好ましい。   As shown in FIG. 3A, the protrusions 4 are preferably provided on both the left slope 2a and the right slope 2b. Thereby, when light strikes the building board, a shadow is formed on the slope 2 by the protrusion 4, and the viewer can visually recognize that the protrusion 1 protrudes more, thereby enhancing the three-dimensional effect. . Even if the top 3 and the slope 2 have the same vertical length, the vertical length of the slope 2 seems to be longer than the vertical length of the top 3 due to the shadow of the protrusion 4. Can be visually recognized as if the convex portion 1 is more protruding, and the stereoscopic effect can be enhanced. The protrusion 4 may be provided only on the left slope 2a, or may be provided only on the right slope 2b as shown in FIG. In the recess formed between the adjacent protrusions 1, it is preferable that a plurality of protrusions 4 are provided on at least one of the left and right slopes 2.

突起部4の左右方向の幅は、適宜設定されるが、例えば、0.2〜3mmにすることができる。突起部4の突出高さは、0.2mm以上であることが好ましい。この範囲であれば、陰影を形成しやすく、より立体感を強調することができる。突起部4の突出高さは適宜設定されるが、一般的な建築板の厚みから、突起部4の突出高さの上限値は、例えば、2mm程度である。突起部4の突出高さとは、凸部1の表面からの高さを意味する。   The width in the left-right direction of the protrusion 4 is appropriately set, and can be set to, for example, 0.2 to 3 mm. The protrusion height of the protrusion 4 is preferably 0.2 mm or more. If it is this range, it will be easy to form a shadow and a three-dimensional effect can be emphasized more. Although the protrusion height of the protrusion part 4 is set suitably, the upper limit of the protrusion height of the protrusion part 4 is about 2 mm from the thickness of a general building board, for example. The protrusion height of the protrusion 4 means the height from the surface of the protrusion 1.

突起部4は、リブ状の突起であることが好ましい。突起部4がリブ状の突起であれば、陰影を形成しやすいため、突起部4の凹凸を強調しやすく、より立体感を増大させることができる。リブ状の突起は、斜面2の傾斜方向に略直交する方向に設けられていることが好ましい。斜面2の傾斜方向に略直交する方向に設けられるリブ状の突起は、凸部1の上下方向全長に渡って設けられていることがさらに好ましい。これによって、より陰影を形成しやすくなり、立体感をさらに増大させることができる。突起部4は、細かな突起であってもよい。細かな突起としては、梨地調やスタッコ調の突起などが例示される。   The protrusion 4 is preferably a rib-like protrusion. If the protrusion 4 is a rib-shaped protrusion, it is easy to form a shadow, so that the unevenness of the protrusion 4 can be easily emphasized, and the stereoscopic effect can be further increased. The rib-shaped protrusions are preferably provided in a direction substantially perpendicular to the inclination direction of the slope 2. More preferably, the rib-like protrusions provided in a direction substantially orthogonal to the inclination direction of the slope 2 are provided over the entire length of the convex part 1 in the vertical direction. As a result, it becomes easier to form a shadow, and the stereoscopic effect can be further increased. The protrusion 4 may be a fine protrusion. Examples of the fine protrusions include satin-like and stucco-like protrusions.

凸部1に突起部4を形成する方法としては、例えば、凸部1と一体成形してもよく、凸部1の成形後に切削加工によって形成してもよい。また、突起部4が細かな突起である場合、砂等の粒子を散布して定着させることによって形成してもよい。   As a method of forming the protrusion 4 on the protrusion 1, for example, the protrusion 4 may be formed integrally with the protrusion 1, or may be formed by cutting after forming the protrusion 1. Moreover, when the protrusion part 4 is a fine protrusion, you may form by spraying particles, such as sand, and fixing.

斜面2において、図2(b)のように、突起部4の密度が、凸部1の中央部側から端部側に向かって、高くなることが好ましい。これにより、凸部1に光が当たった場合に、凸部1の斜面2において、凸部1の中央部側から端部側に向かって突起部4による影がだんだん濃くなる。そのため、観る人に、凸部1がより高く突出しているように視認させることができ、建築板の立体感を強調させることができる。なお、突起部4の密度とは、突起部4を配設する密度を意味する。   On the slope 2, as shown in FIG. 2B, it is preferable that the density of the protrusions 4 increases from the central part side to the end part side of the convex part 1. Thereby, when light strikes the convex portion 1, on the slope 2 of the convex portion 1, the shadow by the protruding portion 4 gradually increases from the central portion side to the end portion side of the convex portion 1. Therefore, it can be made to visually recognize that the convex part 1 protrudes higher, and the three-dimensional effect of a building board can be emphasized. Note that the density of the protrusions 4 means the density at which the protrusions 4 are disposed.

斜面2において、図2(b)のように、突起部4の突出高さが、凸部1の中央部側から端部側に向かって、高くなることが好ましい。これにより、凸部1に光が当たった場合に、凸部1の斜面2において、凸部1の中央部側から端部側に向かって突起部4による影が濃くなる。そのため、観る人に、凸部1がより高く突出しているように視認させることができ、建築板の立体感を増大させることができる。また、図2(b)のように、斜面2において、突起部4の密度が、凸部1の中央部側から端部側に向かって、高くなると共に、突起部4の突出高さが、凸部1の中央部側から端部側に向かって、高くなることがさらに好ましい。これにより、建築板の立体感をさらに強調させることができる。   On the slope 2, as shown in FIG. 2B, it is preferable that the protruding height of the protruding portion 4 increases from the central portion side to the end portion side of the protruding portion 1. Thereby, when light strikes the convex portion 1, on the slope 2 of the convex portion 1, the shadow by the protruding portion 4 becomes deeper from the central portion side to the end portion side of the convex portion 1. Therefore, it can be made to visually recognize as the convex part 1 protrudes higher, and the three-dimensional effect of a building board can be increased. Further, as shown in FIG. 2B, on the slope 2, the density of the protrusions 4 increases from the center side to the end side of the protrusions 1, and the protrusion height of the protrusions 4 is It is more preferable that the height increases from the central part side to the end part side of the convex part 1. Thereby, the three-dimensional effect of a building board can be further emphasized.

陰影形成構造40は、突起部4のみで形成されていてもよく、複数種類を組み合わせて形成してもよい。例えば、突起部4の間には、必要に応じて、突起部4よりも微細な凹凸を設けてもよい。微細な凹凸は、細かなシボであってもよく、筋状であってもよい。突起部4の間に突起部4よりも微細な凹凸を設けることで、建築板の立体感をより増大することができる。例えば、斜面2には突起部4が設けられ、頂部3には、突起部4よりも微細な凹凸が設けられていてもよい。   The shadow forming structure 40 may be formed only by the protrusions 4 or may be formed by combining a plurality of types. For example, unevenness finer than the protrusions 4 may be provided between the protrusions 4 as necessary. The fine irregularities may be fine wrinkles or streaks. By providing unevenness between the protrusions 4 that is finer than that of the protrusions 4, the three-dimensional effect of the building board can be further increased. For example, the slope 2 may be provided with the protrusion 4, and the top 3 may be provided with unevenness finer than the protrusion 4.

図2(b)や図3(a)(b)のように、頂部3の表面は、平坦であることが好ましい。これにより、凸部1に光が当たった場合に、斜面2の陰影形成構造40による影が強調され、凸部1がより高く突出しているように視認させることができ、建築板の立体感を増大することができる。また、図4のように、頂部3には、陰影形成構造40が設けられていてもよい。頂部3に陰影形成構造40が設けられる場合は、頂部3の陰影形成構造40によって形成される影が、斜面2の陰影形成構造40によって形成される影よりも薄くなるように、陰影形成構造40が設けられていることが好ましい。例えば、図4のように、頂部3の陰影形成構造40が突起部4bである場合は、頂部3の突起部4bは、斜面2の突起部4よりも、密度が低いことが好ましく、突出高さが低いことが好ましい。これにより、頂部3よりも斜面2の陰影形成構造40が強調され、建築板の立体感を増大することができる。   Like FIG.2 (b) and FIG.3 (a) (b), it is preferable that the surface of the top part 3 is flat. Thereby, when the light hits the convex part 1, the shadow by the shadow formation structure 40 of the slope 2 is emphasized, and it can be made to visually recognize as the convex part 1 protrudes higher, and the three-dimensional effect of the building board can be achieved. Can be increased. Further, as shown in FIG. 4, the top 3 may be provided with a shadow forming structure 40. When the shadow forming structure 40 is provided on the top 3, the shadow forming structure 40 is so formed that the shadow formed by the shadow forming structure 40 on the top 3 is thinner than the shadow formed by the shadow forming structure 40 on the slope 2. Is preferably provided. For example, as shown in FIG. 4, when the shadow forming structure 40 of the top 3 is the protrusion 4b, the protrusion 4b of the top 3 preferably has a lower density than the protrusion 4 of the slope 2, and the protrusion height Is preferably low. Thereby, the shadow formation structure 40 of the slope 2 is emphasized rather than the top part 3, and the three-dimensional effect of a building board can be increased.

縦目地部5の左右に陰影形成構造40を設けることが好ましい。これにより、縦目地部5を強調することができ、曲面タイルを連想させやすくなる。また、左右に隣り合う凸部1の間の凹部を強調することができるため、立体感を増大させることができる。縦目地部5の左右に設けられる陰影形成構造40は突起部4aであることが好ましい。突起部4aは、他の突起部4よりも突出高さが高いことが好ましい。これにより、より縦目地部5を強調することができる。   It is preferable to provide shadow forming structures 40 on the left and right of the vertical joint 5. Thereby, the vertical joint part 5 can be emphasized and it becomes easy to associate a curved tile. Moreover, since the recessed part between the convex parts 1 adjacent to right and left can be emphasized, a three-dimensional effect can be increased. It is preferable that the shadow forming structures 40 provided on the left and right of the vertical joint 5 are the protrusions 4a. The protrusion 4 a preferably has a higher protrusion height than the other protrusions 4. Thereby, the vertical joint part 5 can be emphasized more.

凸部1の配置方法は、特に限定されるものではないが、立体感を強調させることができる点で、図1に示すように、千鳥状に配置することが好ましい。凸部1を千鳥状に配置することにより、上の列の凸部1の頂部3と下の列の凸部1の頂部3とが、左右方向で重なりにくくなる。これにより、建築板に上方から光が当たった場合に、上の列の凸部1の影が、下の列の表面に形成されやすく、立体感を強調することができる。また、上の列の凸部1の頂部3の影と、下の列の凸部1の陰影形成構造40の影が合わさって、上の列の凸部1の下により大きな影を形成しやすくなる。これにより、観る人に、上の列の凸部1が実際より高く突出しているように視認させることができ、建築板の立体感をより増大させることができる。   Although the arrangement method of the convex part 1 is not specifically limited, As shown in FIG. 1, it is preferable to arrange in a zigzag form by the point which can emphasize a three-dimensional effect. By arranging the convex portions 1 in a staggered manner, the top portions 3 of the convex portions 1 in the upper row and the top portions 3 of the convex portions 1 in the lower row are difficult to overlap in the left-right direction. Thereby, when light hits a building board from the upper part, the shadow of the convex part 1 of an upper row | line | column is easy to be formed on the surface of a lower row | line, and can emphasize a three-dimensional effect. In addition, the shadow of the top 3 of the convex portion 1 in the upper row and the shadow of the shadow forming structure 40 of the convex portion 1 in the lower row are combined to easily form a larger shadow below the convex portion 1 in the upper row. Become. Thereby, it can be made to visually recognize that the convex part 1 of the upper row | line | column protrudes higher than it is actually, and the three-dimensional effect of a building board can be increased more.

凸部1は、上下に隣り合った凸部1の縦目地部5が一直線になるように、配置してもよい。この場合、上の凸部1の頂部3と下の凸部1の頂部3とが左右方向で完全に一致しないようにすることが好ましい。その方法としては、例えば、上の凸部1の頂部3と下の凸部1の頂部3の中心位置が左右方向でずれるような形状の凸部1を上下に配置したり、頂部3の横の長さが異なる凸部1を上下に配置したりすることができる。これにより、上方から光が当たった場合に、上の凸部1の影が下の凸部1の表面に形成されやすく、立体感を強調することができる。   The convex portions 1 may be arranged so that the vertical joints 5 of the convex portions 1 adjacent to each other in the vertical direction are in a straight line. In this case, it is preferable that the top part 3 of the upper convex part 1 and the top part 3 of the lower convex part 1 do not completely coincide in the left-right direction. As the method, for example, the convex portions 1 having such shapes that the center positions of the top portion 3 of the upper convex portion 1 and the top portion 3 of the lower convex portion 1 are shifted in the left-right direction are arranged vertically, The convex portions 1 having different lengths can be arranged vertically. Thereby, when the light hits from the upper part, the shadow of the upper convex part 1 is easy to be formed on the surface of the lower convex part 1, and a three-dimensional effect can be emphasized.

凸部1の配置方法としては、同じ大きさの凸部1を複数配置してもよく、横の長さが異なる凸部1が混在していてもよく、縦の長さが異なる凸部1が混在していてもよい。例えば、横の長さが同じ凸部1が左右方向に一列に形成され、横目地部6を介して上下の列に、横の長さが異なる凸部1を左右方向に一列に形成している建築板であってもよい。これにより、建築板に光が当たった場合に、光がどの角度で当たっても、建築板の表面上に凸部1による影が不規則に形成されやすくなり、凸部1による凹凸を強調することができ、意匠性を向上させることができる。   As a method for arranging the convex portions 1, a plurality of convex portions 1 having the same size may be arranged, convex portions 1 having different horizontal lengths may be mixed, or convex portions 1 having different vertical lengths. May be mixed. For example, the convex portions 1 having the same horizontal length are formed in a row in the left-right direction, and the convex portions 1 having different horizontal lengths are formed in a row in the horizontal direction via the horizontal joint portion 6. It may be a building board. Thereby, when light hits a building board, it becomes easy to form the shadow by the convex part 1 on the surface of a building board irregularly regardless of what angle light hits, and the unevenness | corrugation by the convex part 1 is emphasized. And design properties can be improved.

また、縦の長さが異なる凸部1を左右に隣接して一列に配置して建築板を形成してもよい。すなわち、横目地部6の上下の幅は、建築板の左右方向に一定であってもよく、一定でなくてもよい。また、建築板において、横目地部6の上下幅が左右方向に一定である列と、一定でない列とが混在していてもよい。横目地部6の上下の幅は、特に限定されないが、例えば、1.5〜10mmである。   Moreover, you may form the building board by arrange | positioning the convex part 1 from which vertical length differs adjacent to right and left in a line. That is, the vertical width of the horizontal joint portion 6 may be constant in the left-right direction of the building board or may not be constant. Moreover, in a building board, the row | line | column whose vertical width of the horizontal joint part 6 is constant in the left-right direction, and the row | line | column which is not constant may be mixed. Although the vertical width of the horizontal joint part 6 is not specifically limited, For example, it is 1.5-10 mm.

また、縦の長さ、横の長さ、高さが異なる凸部1をランダムに配置してもよいが、左右方向に位置する凸部1は、その縦の長さを略同等とするのが好ましい。
上記の建築板は、例えば、セメント硬化物で形成される窯業系基板、合板などの木質系基板、ステンレス剛板などの金属系基板、樹脂基板等として得ることができる。
Moreover, although the convex part 1 from which vertical length, horizontal length, and height differ may be arrange | positioned at random, the convex part 1 located in the left-right direction makes the vertical length substantially equivalent. Is preferred.
The building board can be obtained, for example, as a ceramic board formed of a hardened cement material, a wooden board such as plywood, a metal board such as a stainless rigid board, a resin board, or the like.

建築板の表面には、塗装を施してもよい。塗装方法としては、ロールコータ塗装、スプレー塗装、インクジェット塗装等を用いることができる。塗装は、例えば、単色塗装であっても、頂部3と斜面2とを塗り分ける2色塗装であってもよい。   The surface of the building board may be painted. As a coating method, roll coater coating, spray coating, inkjet coating, or the like can be used. The coating may be, for example, a single color coating or a two-color coating that separates the top 3 and the slope 2.

従来、ロールコータ塗装等で、凹凸を有する建築板の凸部と凹部とを塗り分ける2色塗装では、凸部の形状が、曲線状である場合は、凸部と凹部との境界がわかりにくく、2色の塗り分けが困難であった。しかし、本発明に係る建築板では、斜面2に陰影形成構造40が設けられているため、陰影形成構造40を目印として、2色の塗り分ける境界がわかりやすくなる。また、陰影形成構造40が突起部4である場合、突起部4が設けられていることにより、突起部4が設けられていない建築板よりも、頂部3から斜面2にかけての高さの変化が少なく、塗装ローラーが突起部4に接触するため、塗装がしやすくなる。   Conventionally, in the two-color coating that separates the projections and depressions of the uneven building board by roll coater coating, etc., if the shape of the projections is curved, the boundary between the projections and depressions is difficult to understand It was difficult to separate the two colors. However, in the building board according to the present invention, since the shadow forming structure 40 is provided on the slope 2, it becomes easy to understand the boundary between the two colors with the shadow forming structure 40 as a mark. Moreover, when the shadow formation structure 40 is the protrusion part 4, since the protrusion part 4 is provided, the change of the height from the top part 3 to the slope 2 rather than the building board in which the protrusion part 4 is not provided is provided. Since there are few coating rollers and the protrusion part 4 contacts, it becomes easy to paint.
