The surface plate 1 is comprised by the metal plate, for example, is comprised by the coated steel plate. As shown in FIG. 1, the surface plate 1 is formed with a plurality of convex portions 10 arranged in the vertical and horizontal directions. Between each convex part 10, the pseudo joint 2 (henceforth only the joint 2) which is the joint of the convex parts 10 is formed. The building board of this embodiment is provided with the vertical joint 21 extended along the width direction of a building board as the joint 2, and the horizontal joint 22 extended along the length direction of a building board. A wood grain pattern is formed on the surface of each convex portion 10 of the present embodiment, and each convex portion 10 is formed in a shape simulating a wooden board. The wood grain pattern of the surface plate 1 is formed by protrusions extending in the length direction, and is formed by, for example, roll molding or press molding.
芯材６は、図２に示すように、表面板１の裏側に設けられている。芯材６は、断熱材により構成されており、例えば、ポリイソシアヌレートフォームやポリウレタンなどにより構成される。裏面材７は、芯材６の裏面に設けられている。裏面材７は、例えば、アルミラミネート加工されたクラフト紙により構成される。 The core material 6 is provided on the back side of the surface plate 1 as shown in FIG.

The back material 7 is made of, for example, kraft paper that has been laminated with aluminum.
本実施形態の建築板には、図１に示すように、各凸部１０の表面に明領域３１と暗領域３２とを形成する明暗領域形成部３が設けられている。明暗領域形成部３は、例えば、太陽光などのような光源からの一方向の光を受けると、明領域３１と暗領域３２との両方を、各凸部１０の表面に形成する。明暗領域形成部３は、図２に示すように、各凸部１０の表面に形成された複数の第一突条４と、複数の第二突条５とを備えている。 As shown in FIG. 1, the building board of this embodiment is provided with a light / dark region forming portion 3 that forms a light region 31 and a dark region 32 on the surface of each convex portion 10. For example, when receiving light in one direction from a light source such as sunlight, the light / dark region forming unit 3 forms both the light region 31 and the dark region 32 on the surface of each convex portion 10. As shown in FIG. 2, the light / dark region forming unit 3 includes a plurality of first ridges 4 and a plurality of second ridges 5 formed on the surface of each convex portion 10.
以下においては、光源が、建築板に対して前斜め上方に位置する場合に基づいて説明する。 Below, it demonstrates based on the case where a light source is located in front diagonally upward with respect to a building board.
複数の第一突条４は、各凸部１０の表面に明領域３１を形成する。明領域３１とは、凸部１０に光を当てたときに、暗領域３２に比べて明るい領域をいう。各第一突条４は、左右方向に延びており、図３Ａに示すように、断面山形状に形成されている。第一突条４は、突出先端部４１と、突出先端部４１の上下方向の両側に位置する一対の面状部４２とで構成される。 The plurality of first protrusions 4 form a bright region 31 on the surface of each convex portion 10. The bright region 31 is a region that is brighter than the dark region 32 when light is applied to the convex portion 10. Each 1st protrusion 4 is extended in the left-right direction, and is formed in cross-sectional mountain shape, as shown to FIG. 3A. The first protrusion 4 includes a protruding tip 41 and a pair of planar portions 42 located on both sides of the protruding tip 41 in the vertical direction.
突出先端部４１は、断面において円弧状に湾曲している。突出先端部４１は、第一突条４の突出基部に対し、平面視において、下方側（第一の側）に偏って位置している。言い換えると、突出先端部４１は、第一突条４の幅方向のうち光源側とは反対側に偏って位置している。ここで「突出先端部４１が偏る」とは、突出先端部４１が突条４の幅方向の中央に位置せずに、幅方向のいずれか側に位置していることをいう。 The protruding tip 41 is curved in an arc shape in cross section. The protruding tip portion 41 is located on the lower side (first side) in a plan view with respect to the protruding base portion of the first protrusion 4. In other words, the protruding tip portion 41 is located on the opposite side to the light source side in the width direction of the first protrusion 4. Here, “the protruding tip portion 41 is biased” means that the protruding tip portion 41 is not located at the center in the width direction of the protrusion 4 but is located on either side in the width direction.
一対の面状部４２は、断面において直線状に形成されている。一対の面状部４２は、光源側に位置する幅広部４３と、突出先端部４１を介して幅広部４３の反対側に位置する幅狭部４４とを備えている。幅広部４３は、幅狭部４４に比べて幅が広く形成されている。幅広部４３は、光源側に臨んでいるため、光を受けることができるように構成されているのに対し、幅狭部４４は、光源とは反対側に臨んでいるため陰になる。したがって、複数の第一突条４を離れた位置から見ると、光を受ける面状部４２の面積の合計が、陰になる面状部４２の面積の合計よりも大きいため、明領域３１を形成することができる。 The pair of planar portions 42 are formed in a straight line in the cross section. The pair of planar portions 42 includes a wide portion 43 located on the light source side and a narrow portion 44 located on the opposite side of the wide portion 43 via the protruding tip portion 41. The wide portion 43 is formed wider than the narrow portion 44. Since the wide portion 43 faces the light source side, it is configured to receive light, whereas the narrow portion 44 is shaded because it faces the opposite side of the light source. Accordingly, when the plurality of first protrusions 4 are viewed from a position away from each other, the total area of the planar portions 42 that receive light is larger than the total area of the planar portions 42 that are shaded. Can be formed.
複数の第二突条５は、図２に示すように、各凸部１０の表面に暗領域３２を形成する。暗領域３２とは、凸部１０に光を当てたときに、明領域３１に比べて暗い領域をいう。各第二突条５は、左右方向に延びており、図３Ｂに示すように、断面山形状に形成されている。第二突条５は、第一突条４と同様に、突出先端部５１と、突出先端部５１の上下方向の両側に位置する一対の面状部５２とで構成される。 As shown in FIG. 2, the plurality of second ridges 5 form a dark region 32 on the surface of each convex portion 10. The dark area 32 is an area darker than the bright area 31 when light is applied to the convex portion 10. Each 2nd protrusion 5 is extended in the left-right direction, and is formed in cross-sectional mountain shape, as shown to FIG. 3B. Similar to the first ridge 4, the second ridge 5 includes a protruding tip 51 and a pair of planar portions 52 positioned on both sides of the protruding tip 51 in the vertical direction.
突出先端部５１は、断面において円弧状に湾曲している。突出先端部５１は、第二突条５の突出基部に対し、平面視において、上方側（第二の側）に偏って位置している。言い換えると、突出先端部５１は、第二突条５の幅方向のうち光源が位置する側に偏って位置している。 The protruding tip 51 is curved in an arc shape in cross section. The projecting tip 51 is biased toward the upper side (second side) in plan view with respect to the projecting base of the second protrusion 5. In other words, the protruding tip 51 is biased to the side where the light source is located in the width direction of the second protrusion 5.
一対の面状部５２は、第一突条４と同様に、断面において直線状に形成されている。一対の面状部５２は、光源側に位置する幅狭部５４と、幅広部５３とは突出先端部５１を介した反対側に位置する幅広部５３とを備えている。幅狭部５４は、幅広部５３に比べて幅が狭く形成されている。幅狭部５４は、光源側に臨んでいるため、光を受けることができるように構成されているのに対し、幅広部５３は、光源とは反対側に臨んでいるため陰になる。したがって、複数の第二突条５を離れた位置から見ると、陰になる面状部５２の面積の合計が、光を受ける面状部５２の面積の合計よりも大きいため、暗領域３２を形成することができる。 The pair of planar portions 52 are formed in a straight line in the cross section, similarly to the first protrusion 4. The pair of planar portions 52 includes a narrow portion 54 located on the light source side, and a wide portion 53 located on the opposite side of the wide portion 53 with the protruding tip 51 interposed therebetween. The narrow part 54 is formed narrower than the wide part 53. Since the narrow portion 54 faces the light source side, it is configured to receive light, whereas the wide portion 53 is shaded because it faces the opposite side of the light source. Accordingly, when the plurality of second protrusions 5 are viewed from a position away from each other, the total area of the shaded planar portions 52 is larger than the total area of the planar portions 52 that receive light. Can be formed.
なお、面状部４２，５２にいう「直線状」とは、厳密な意味での直線状のみを言うのではなく、直線状に近いものも含み、すなわち緩やかにたわんだ形状も含む。つまり、ほぼ直線状に見えるような形状は、ここでいう「直線状」の範疇であるとする。 The “straight line shape” referred to in the planar portions 42 and 52 does not mean only a straight line shape in a strict sense, but includes a shape close to a straight line shape, that is, includes a gently bent shape. That is, it is assumed that the shape that looks almost linear falls within the category of “linear” as used herein.
このような構成の第一突条４は、図２に示すように、上下方向に並んでおり、複数の第一突条４が、その間に第二突条５が入り込むことなく連続して形成されている。また、複数の第二突条５についても、上下方向に並んでおり、複数の第二突条５が連続して形成されている。複数の第一突条４と複数の第二突条５は、１つの凸部１０の表面において上下に並んで配置され、これにより、１つの凸部１０に、明領域３１と暗領域３２とを形成することができる。 As shown in FIG. 2, the first protrusions 4 having such a configuration are arranged in the vertical direction, and a plurality of first protrusions 4 are continuously formed without the second protrusions 5 entering between them. Has been. The plurality of second ridges 5 are also arranged in the vertical direction, and the plurality of second ridges 5 are continuously formed. The plurality of first ridges 4 and the plurality of second ridges 5 are arranged side by side on the surface of one convex portion 10, whereby a bright region 31 and a dark region 32 are formed on one convex portion 10. Can be formed.
明領域３１と暗領域３２とが形成される複数の凸部１０は、図１に示すように、上下方向に隣り合う凸部１０同士において、複数の第一突条４と複数の第二突条５との位置関係が異なる。つまり、隣り合う凸部１０に光源からの光が照射されると、上下方向に隣り合う凸部１０同士で、明領域３１と暗領域３２の現れ方が異なることになる。この結果、複数の建築板を左右方向に並べて設置した場合において、これらが仮に上下方向にずれた場合にも、ズレが目立たないようにできる。 As shown in FIG. 1, the plurality of convex portions 10 in which the bright region 31 and the dark region 32 are formed are, in the convex portions 10 adjacent in the vertical direction, a plurality of first protrusions 4 and a plurality of second protrusions. The positional relationship with Article 5 is different. That is, when the light from the light source is irradiated to the adjacent convex portions 10, the appearance of the bright region 31 and the dark region 32 is different between the convex portions 10 adjacent in the vertical direction. As a result, when a plurality of building boards are installed side by side in the left-right direction, even if they are shifted in the up-down direction, the deviation can be made inconspicuous.
具体的に説明すると、図１において、最上部の凸部１０（以下、第１の凸部１１）と、二段目の凸部１０（以下、第２の凸部１２）とで、複数の第一突条４と複数の第二突条５との位置関係が異なっている。第１の凸部１１は、上半部において複数の第二突条５が形成され、下半部において複数の第一突条４が形成されている。一方、第２の凸部１２は、上側から順に、約１／５の領域において複数の第二突条５が形成され、２／５の領域において複数の第一突条４が形成され、２／５の領域において複数の第二突条５が形成されている。 More specifically, in FIG. 1, the uppermost convex portion 10 (hereinafter referred to as the first convex portion 11) and the second-stage convex portion 10 (hereinafter referred to as the second convex portion 12) The positional relationship between the first protrusion 4 and the plurality of second protrusions 5 is different. As for the 1st convex part 11, the some 2nd protrusion 5 is formed in the upper half part, and the some 1st protrusion 4 is formed in the lower half part. On the other hand, in order from the upper side, the second protrusion 12 has a plurality of second ridges 5 formed in a region of about 1/5, and a plurality of first ridges 4 formed in a region of 2/5. A plurality of second protrusions 5 are formed in the region of / 5.
ここで、仮に、複数の第一突条４と複数の第二突条５との位置関係が、幅方向に並ぶ凸部１０同士において同じ関係とすると、明領域３１が幅方向に等ピッチで並ぶことになる。このとき、長さ方向に並ぶ建築板において、建築板同士が幅方向にずれると、明領域３１が幅方向にずれ、そのズレが目立つ。これに対し、本実施形態の建築板では、明領域３１と暗領域３２との位置関係が、幅方向に並ぶ凸部１０で異なるため、仮に建築板同士が幅方向にずれたとしても、その位置ずれが目立つのを抑制できる。 Here, if the positional relationship between the plurality of first ridges 4 and the plurality of second ridges 5 is the same in the convex portions 10 arranged in the width direction, the bright regions 31 are equally pitched in the width direction. Will be lined up. At this time, in the building boards arranged in the length direction, when the building boards are shifted in the width direction, the bright region 31 is shifted in the width direction, and the deviation is conspicuous. On the other hand, in the building board of the present embodiment, the positional relationship between the bright area 31 and the dark area 32 is different in the convex portions 10 arranged in the width direction, so even if the building boards are shifted in the width direction, It can suppress that position shift is conspicuous.
また、本実施形態の複数の凸部１０は、上下方向に並ぶだけでなく、左右方向（つまり突条４，５の長手方向に平行な方向）に一列に並ぶように配置されている。左右方向に並ぶ凸部１０に着目すると、左右方向に縦目地２１を介して並ぶ明領域３１が連続し、かつ、縦目地２１を介して並ぶ暗領域３２が連続している。 Further, the plurality of convex portions 10 of this embodiment are arranged not only in the vertical direction but also in a line in the left-right direction (that is, the direction parallel to the longitudinal direction of the protrusions 4 and 5). Focusing on the convex portions 10 arranged in the left-right direction, the bright regions 31 arranged via the vertical joints 21 are continuous in the left-right direction, and the dark regions 32 arranged via the vertical joints 21 are continuous.
このため、この建築板に光源からの光が当たると、左右方向に延びる帯状の明領域３１が形成される。なお、ここで言う「明領域が連続」とは、明領域が帯状に見える程度に連続していればよく、多少、上下方向にずれていても帯状と感得できればその範疇に含まれる。もちろん、目地２を介して隣り合う状態も「明領域が連続」するという。 For this reason, when the light from a light source hits this building board, the strip | belt-shaped bright area | region 31 extended in the left-right direction is formed. Note that “the bright region is continuous” as long as it is continuous as long as the bright region looks like a band, and even if it is slightly shifted in the vertical direction, it is included in the category. Of course, the state adjacent to each other via the joint 2 is said to be “the bright region is continuous”.
一方、これとは対照的に、左右方向に縦目地２１を介して並ぶ明領域３１が不連続であり、かつ、縦目地２１を介して並ぶ暗領域３２が不連続であってもよい。この場合、明領域３１が帯状には現れないが、明領域３１および暗領域３２が建築板全体にランダムに現れる。ここでいう「不連続」とは、左右方向に並ぶ明領域が、明領域の幅方向の一部で重なっていてもよいし、互いに離れていてもよい。 On the other hand, the bright regions 31 arranged in the left-right direction via the vertical joints 21 may be discontinuous, and the dark regions 32 arranged via the vertical joints 21 may be discontinuous. In this case, although the bright area 31 does not appear in a strip shape, the bright area 31 and the dark area 32 appear randomly on the entire building board. Here, “discontinuous” means that the bright areas arranged in the left-right direction may overlap with each other in the width direction of the bright areas, or may be separated from each other.
また、本実施形態の突条４，５は、図１に示すように、全体として木目柄を形成している。したがって、建築板に光源からの光が当たると、木目柄の中に明領域３１と暗領域３２とが形成され、木目柄と明暗とを組み合わせた従来にないデザイン性を付与することができる。しかも、複数の建築板を左右方向に連続するように設置すれば、明領域３１が帯状に連続するように現われるため、木目柄に加えて、明暗によるストライプの印象を与えることができる。この結果、建物外観の見栄えにおいて、単なる木目柄ではなく、明暗による変化を与えることができる。 Further, as shown in FIG. 1, the protrusions 4 and 5 of the present embodiment form a wood grain pattern as a whole. Therefore, when the light from the light source hits the building board, the bright region 31 and the dark region 32 are formed in the wood grain pattern, and an unprecedented design that combines the wood grain pattern and the light and darkness can be imparted. In addition, if a plurality of building boards are installed so as to be continuous in the left-right direction, the bright region 31 appears so as to be continuous in a strip shape, so that in addition to the wood grain pattern, an impression of light and dark stripes can be given. As a result, in the appearance of the building, a change due to light and darkness can be given instead of a simple grain pattern.
（効果）
以上、説明したように、本実施形態の建築板は、以下の構成を備える。すなわち、本実施形態の建築板は、表面に複数の凸部１０が形成された建築板である。複数の凸部１０の各々の表面には、各凸部１０の表面に明領域３１と暗領域３２とを形成する明暗領域形成部３が設けられている。明暗領域形成部３は、明領域３１を形成する複数の第一突条４と、複数の第一突条４に並ぶように形成され暗領域３２を形成する複数の第二突条５とを備える。複数の第一突条４の各々の突出先端部４１は、第一突条４の幅方向のうちの第一の側に偏っている。複数の第二突条５の各々の突出先端部５１は、幅方向のうちの第一の側とは反対側の第二の側に偏っている。この構成によれば、建築板に一方向から光が当たると、各凸部１０において、明領域３１と暗領域３２とが形成され、すなわち、各凸部１０の表面に明暗を生じさせることができる。この結果、本実施形態の建築板によれば、単調なデザインにはなりにくく、明暗を利用した多様なデザインを実現できる。

In other words, each of the plurality of first protrusions 4 and the plurality of second protrusions 5 of the present embodiment is such that each of the protruding tip portions 51 and 41 is curved and both sides of the protruding tip portions 41 and 51 in the width direction in the cross section. Is formed in a mountain shape inclined linearly. According to this structure, even if a building board is metal siding, it can prevent that a hole opens in the protrusion front-end | tip part 51 of the 1st protrusion 4 and the 2nd protrusion 5, and, Manufacture is easy because both sides are linear in cross section.
また、本実施形態の建築板は、次の付加的な構成を有する。すなわち、本実施形態の建築板は、複数の凸部１０が、建築板の幅方向に複数並ぶように配置されている。複数の第一突条４と複数の第二突条５との複数の凸部１０の各々における位置関係は、幅方向に隣り合う凸部１０同士で異なっている。この構成によれば、複数の建築板を長さ方向に並ぶように配置した場合において、建築板同士が幅方向に位置ずれしていたとしても、当該位置ずれが目立たないようにできる。 Moreover, the building board of this embodiment has the following additional structure. That is, the building board of the present embodiment is arranged such that a plurality of convex portions 10 are arranged in the width direction of the building board. The positional relationship between the plurality of first protrusions 4 and the plurality of second protrusions 5 in each of the plurality of protrusions 10 is different between the protrusions 10 adjacent in the width direction. According to this configuration, when a plurality of building boards are arranged in the length direction, even if the building boards are displaced in the width direction, the positional deviation can be made inconspicuous.
また、本実施形態の建築板は、次の付加的な構成を有する。すなわち、本実施形態の建築板は、明暗領域形成部３が、木目柄を形成している。この構成によれば、木目柄として外壁を形成しつつも、明暗を効果的に利用した多様なデザインを形成することが可能となる。 Moreover, the building board of this embodiment has the following additional structure. That is, in the building board of the present embodiment, the light and dark area forming unit 3 forms a wood grain pattern. According to this configuration, it is possible to form various designs using light and dark effectively while forming the outer wall as a wood grain pattern.
また、本実施形態の建築板は、次の付加的な構成を有する。すなわち、本実施形態の複数の凸部１０は、第一突条４および第二突条５の長手方向に平行な方向に一列に並ぶように配置されている。複数の凸部１０の並ぶ方向において、複数の明領域３１が連続し、かつ、複数の暗領域３２が連続している。この構成によれば、建築板に光が当たると、明領域３１が建築板全体に帯状に現われ、従来にないデザイン性を付与することができる。 Moreover, the building board of this embodiment has the following additional structure. That is, the plurality of convex portions 10 of the present embodiment are arranged in a line in a direction parallel to the longitudinal direction of the first protrusion 4 and the second protrusion 5. In the direction in which the plurality of convex portions 10 are arranged, a plurality of bright regions 31 are continuous and a plurality of dark regions 32 are continuous. According to this configuration, when the building board is exposed to light, the bright region 31 appears in a strip shape on the entire building board, and an unprecedented design can be imparted.
また、本実施形態の建築板は、次の構成を有していてもよい。すなわち、複数の凸部１０は、第一突条４および第二突条５の長手方向に平行な方向に一列に並ぶように配置されている。複数の凸部１０の並ぶ方向において、複数の明領域３１が不連続であり、かつ、複数の暗領域３２が不連続である。この構成によれば、建築板に光が当たると、明領域３１が建築板全体にランダムに現われ、従来にないデザイン性を付与することができる。また、仮に左右方向に隣接する建築板同士に上下方向へのずれが生じても、明領域３１がランダムに現れるため、ズレが目立たないようにできる。 Moreover, the building board of this embodiment may have the following structure. That is, the plurality of convex portions 10 are arranged in a line in a direction parallel to the longitudinal direction of the first protrusion 4 and the second protrusion 5. In the direction in which the plurality of convex portions 10 are arranged, the plurality of bright regions 31 are discontinuous and the plurality of dark regions 32 are discontinuous. According to this configuration, when the building board is exposed to light, the bright regions 31 appear randomly on the entire building board, and an unprecedented design can be imparted. In addition, even if the building boards adjacent in the left-right direction are displaced in the up-down direction, the bright region 31 appears at random, so that the deviation can be made inconspicuous.
なお、本実施形態の各突条４，５の突出先端部４１，５１は、断面において弧状に湾曲していたが、例えば、Ｌ字状に屈曲していてもよい。また、面状部４２，５２は直線状でなくてもよい。 In addition, although the protrusion front-end | tip parts 41 and 51 of each protrusion 4, 5 of this embodiment curved in the arc shape in the cross section, you may bend in L shape, for example. Further, the planar portions 42 and 52 may not be linear.
また、本実施形態の各突条は、設計上では図４のように、幅広部４３においては、突条部４の基部側（下側）に凹むように凹状に湾曲しており、幅狭部４４においても下方に凸となるように緩やかに湾曲している。これは、プレス加工時のスプリングバックの作用によって、設計段階で想定する形状と、実際に成形された形状とに差が生じる。したがって本実施形態の突条４，５としては、上述の実際に成形された突条４，５の形状はもちろん、図４のような設計上の形状についても同様の効果を奏することができ、いずれも本発明の範疇である。 Each of the protrusions of the present embodiment is curved in a concave shape so as to be recessed toward the base side (lower side) of the protrusion 4 at the wide portion 43 as shown in FIG. The portion 44 is also gently curved so as to protrude downward. This is caused by a difference between the shape assumed in the design stage and the actually formed shape due to the action of the spring back during the press working. Therefore, as the protrusions 4 and 5 of the present embodiment, the same effect can be achieved not only in the shape of the actually formed protrusions 4 and 5 but also in the design shape as shown in FIG. Both are within the scope of the present invention.
また、本実施形態の建築板は、金属サイディングにより構成されたが、例えば、窯業系のサイディング材であってもよく、本発明の建築板は金属サイディングに限定されない。また、建築板は、横張り用の外壁材でなくてもよく、例えば、縦張り用の外壁材であってもよい。さらに、本実施形態の建築板は、内壁材や、間仕切りに適用してもよく、用途について特に限定されない。なお、建築板を室内で使用する場合、光源は、室内照明等により構成される。 Moreover, although the building board of this embodiment was comprised by the metal siding, a ceramic siding material may be used, for example, and the building board of this invention is not limited to a metal siding. Moreover, the building board may not be the outer wall material for horizontal tension, for example, the outer wall material for vertical tension may be sufficient as it. Furthermore, the building board of this embodiment may be applied to an inner wall material or a partition, and is not particularly limited for use. In addition, when using a building board indoors, a light source is comprised by indoor lighting etc.
その他、本発明の主旨を逸脱しない範囲であれば、適宜設計変更を行うことができる。 In addition, the design can be changed as appropriate within a range not departing from the gist of the present invention.
