Abstract

<P>PROBLEM TO BE SOLVED: To impart an interesting design, which does not feel regular, hard and cool and which is rich in sense of nature, to a building board. <P>SOLUTION: An erosion-and-falling-patterned part 5A is formed in a recessed shape from one side of a top surface of a protrusive block 5 which forms a block-like pattern of a surface of the building board 1. Thus, the sense of nature is imparted to the block-like pattern. Additionally, widths of vertical and lateral recessed grooves 2 and 3, which are interposed among the protrusive blocks 5, are varied so that randomness can be imparted to the block-like pattern. <P>COPYRIGHT: (C)2005,JPO&NCIPI

【発明が解決しようとする課題】
上記従来のブロック調模様にあっては、縦横目地溝の変化が乏しく、また凸ブロック表面には微細凹凸が設けられている場合もあるが、全体的に平坦であり、規則的な堅い冷たい感じの意匠となる。
【0005】
【課題を解決するための手段】
本発明は上記従来の課題を解決する手段として、表面に所定間隔を介して複数個の横凹溝(2) を長手方向に沿って貫設することによって複数段の段部(4) を画定し、各段部(4) には四角形凸ブロック(5) の複数個を縦凹溝(3) を介してそれぞれ配列し、該横凹溝(2) は筋状の巾狭凹溝(2A)と巾広凹溝(2B)との2種類が設定されており、該縦凹溝(3) は筋状の巾狭凹溝(3A)から巾広凹溝(3B)まで巾の異なる複数種類のものが設定されており、相接する上下二つの段部(4) において各縦凹溝(3) は互い違いの位置に設定されており、各凸ブロック(5) の平滑表面には一辺から侵蝕崩落様部分(5A)が凹陥形成されている建築板(1) を提供するものである。
【0006】
各段部(4) において凸ブロック(5) の複数個が筋状の巾狭縦凹溝(3A)を介して連設した部分が一個所または複数個所存在することが望ましく、また該段部(4) にあっては、上側および/または下側の横凹溝(2) が巾広な独立段部と、上下二つの段部(4) が筋状の巾狭凹溝(2A)を介して連設している連設段部とが縦方向で交互に配置されていることが望ましい。更に該建築板(1) 表面に配列されている凸ブロック(5) の全部または一部について該凸ブロック(5) 平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態が相互異なるようにされていることが望ましく、この場合該凸ブロック(5) の複数個の縦横配列からなる柄ユニットの複数種を設定し、該複数種の柄ユニットの凸ブロック(5) 配列様式はすべて共通しており、かつ柄ユニット相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の柄ユニットを適宜選択して建築板(1) 表面に縦および/または横に配列することが望ましく、更に上記柄ユニットにあっては、該凸ブロック(5) の平滑表面に微細凹凸模様を付したものと付してないものとが設定されていてもよい。
【0007】
また該建築板(1) の両端縁は各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている位置に設定し、該建築板(1) の一端縁から巾Wの短冊状板材(1A)を切り出す場合、その切断線Cは各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている位置にあり、更に該建築板(1) の両端縁以外の所定位置で各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている切断線Cを設定することが出来、該切断線Cから一方の側または両方の側に巾aだけおいて切断線Cを設定した場合、該切断線Cは各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れているように各段の凸ブロック(5) と縦凹溝(3) とを配置することが望ましく、この場合該切断線Cと各段の凸ブロック(5) の上面縦辺Eとの間隔Sは15mm以上に設定することが望ましい。
【0008】
更に本発明では、上記の建築板(1) を複数種準備し、該複数種の建築板(1) の表面に配列されている凸ブロック(5) の配列様式はすべて共通しており、かつ該建築板(1) 相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の建築板(1) を適宜選択して構築物躯体表面に縦および/または横に配列張設した構築物が提供される。この場合上記建築板(1) にあっては、該凸ブロック(5) の平滑表面に微細凹凸模様を付したものと付してないものとが設定されていてもよい。
【0009】
【作用】
本発明では縦横目地溝に相当する縦横凹溝(2,3) が筋状の巾狭のものから巾広のものまで巾に変化がつけられており、かつ相接する上下二つの段部(4) において各縦凹溝(3) が互い違いの位置に設定されているので、ブロック調模様にランダム性が付与される。更に上記縦横凹溝(2,3) に囲まれる四角形凸ブロック(5) の平滑表面には一辺から侵蝕崩落様部分(5A)が形成されているので、ブロック調模様の堅い冷たい感じがなくなり、自然感に富んだ面白味のある意匠となる。
【0010】
各段部(4) において凸ブロック(5) の複数個が筋状の巾狭縦凹溝(3A)を介して連設した部分が一個所または複数個所存在すると、各段部(4) における凸ブロック(5) の配列に変化がつけられ面白味が一層増すし、該段部(4) にあっては、上側および/または下側の横凹溝(2) が巾広な独立段部と、上下二つの段部(4) が筋状の巾狭凹溝(2A)を介して連設している連設段部とが縦方向で交互に配置されていると、縦方向の段部(4) の配列にも変化がつけられ、更に意匠の面白味が増す。
【0011】
該建築板(1) 表面に配列されている凸ブロック(5) の全部または一部について該凸ブロック(5) 平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態が相互異なるようにされていると、該凸ブロック(5) の表面のテクスチャーの多様性によって、一律性がなくなり、更に面白味が増す。更に該凸ブロック(5) の複数個の縦横配列からなる柄ユニットの複数種を設定し、該複数種の柄ユニットの凸ブロック(5) 配列様式はすべて共通しており、かつ柄ユニット相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の柄ユニットを適宜選択して建築板(1) 表面に縦および/または横に配列すると、同種の柄ユニットを配列した場合のような柄の繰返し感がなくなり、ランダム性が増して意匠の面白味が向上する。しかし複数種の柄ユニットを予め設定しておき、これを適宜選択して配列するだけであるので意匠のデザインは簡単である。上記柄ユニットにあっては、該凸ブロック(5) の平滑表面に微細凹凸模様を付したものと付してないものとが設定されていると、更に変化が付され面白味が増す。
【0012】
該建築板(1) の両端縁は各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている位置に設定し、該建築板(1) の一端縁から巾Wの短冊状板材(1A)を切り出す場合、その切断線Cは各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている位置にあり、更に該建築板(1) の両端縁以外の所定位置で各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れている切断線Cを設定することが出来、該切断線Cから一方の側または両方の側に巾aだけおいて切断線Cを設定した場合、該切断線Cは各段の凸ブロック(5) の上面縦辺Eから所定間隔S離れているように各段の凸ブロック(5) と縦凹溝(3) とを配置した場合には、該建築板(1) を所定巾Wで縦方向に切断して短冊状板材(1A)を切出す場合、各段について切断線Cは凸ブロック(5) の上面縦辺Eから所定間隔S離れているように設定出来るので、切断線Cに沿う建築板(1) 部分あるいは切断線Cに沿う短冊状板材(1A)の側縁部の機械的強度が確保され、側縁部に欠けが生ずることが有効に防止出来る。
なお切断線Cと凸ブロック(5) 縦辺との間隔は15mmあるいは15mm以上に設定すれば、この間の強度は確実に保証される。
【0013】
上記の建築板(1) を複数種準備し、該複数種の建築板(1) の表面に配列されている凸ブロック(5) の配列様式はすべて共通しており、かつ該建築板(1) 相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の建築板(1) を適宜選択して構築物躯体表面に縦および/または横に配列張設すると、外壁等の構築物において建築板(1) 単位の柄の繰返し感がなくなり、構築物の外観に変化が付され面白味のあるものとなり、更に上記建築板(1) にあっては、該凸ブロック(5) の平滑表面に微細凹凸模様を付したものと付してないものとが設定されていると、更なる変化が付されることによって面白味が増大する。
【0014】
【発明の実施の形態】
本発明を図1〜図7に示す一実施例によって説明する。
図に示す建築板(1) は例えば、木片、木質パルプ、木質繊維束、木毛等の木質補強材を混合した木質セメント板からなり、表面には複数条(5条)の横凹溝(2) が長手方向に沿って貫設されており、該横凹溝(2) の複数条によって複数段(6段)の段部(4) が画定されている。上記横凹溝(2) は筋状の巾狭な凹溝(2A)と、巾広な凹溝(2B)の二種類からなり、上から巾広凹溝(2B)、筋状巾狭凹溝(2A)、巾広凹溝(2B)、巾広凹溝(2B)、筋状巾狭凹溝(2A)の順に配列されており、かくして上から一段目の段部(4) と二段目の段部(4) とは巾広凹溝(2B)によって隔離され、したがって一段目の段部(4) は独立段部となり、二段目の段部(4) と三段目の段部(4) とは筋状巾狭凹溝(2A)を介して連設して連設段部となり、四段目の段部(4) は上下の巾広凹溝(2B)を介して三段目の段部(4) と五段目の段部(4) とから隔離されて独立段部となり、五段目の段部(4) と六段目の段部(4) とは筋状巾狭凹溝(2A)を介して連設して連設段部となっている。そして上下端縁には巾広凹溝(2B)の半分の巾を有する半巾凹溝(2C)が設けられており、該建築板(1) の一対を上下に接続した時、上側の建築板(1) の下端縁の半巾凹溝(2C)と下側の建築板(1) の上端縁の半巾凹溝(2C)とにより巾広凹溝(2B)が形成されるようになっている。したがって建築板(1) を接続して外壁のような構築物を構築した時全体的に独立段部と連設段部とが上下交互に配置される。
【0015】
本実施例では図2に示すように筋状巾狭凹溝(2A)は横断面V字状であり、したがって溝底巾は実質的に0であり、また巾広凹溝(2B)の溝底巾Dは6mm、半巾凹溝(2C)の溝底巾Dは3mmに設定されている。
このように本実施例にあっては、独立段部と連設段部とが縦方向で交互に配置されて縦方向の変化がつけられている。
【0016】
各段部(4) には複数条の縦凹溝(3) を介して複数個の四角形凸ブロック(5) が配列されている。該縦凹溝(3) は筋状の巾狭凹溝(3A)から巾広な凹溝(3B)まで数種類の巾のものが設定されており、各段について筋状巾狭凹溝(3A)を介して凸ブロック(5) の複数個(2個〜4個)が連設している部分が複数個所存在する。本実施例では、図3に示すように筋状巾狭凹溝(3A)は横断面V字状であり、したがって溝底巾は実質的に0であり、また巾広凹溝(3B)の溝底巾Dは5〜25mmの範囲に設定されている。
【0017】
各凸ブロック(5) の4辺側縁は図2、図3に示すように凸ブロック(5) 上面に対して角度θ(θ=60°)で傾斜している。そして図4に示すように各凸ブロック(5) の平滑表面には一辺から侵蝕崩落様部分(5A)が凹陥形成されている。このような侵蝕崩落様部分(5A)によって、ブロック調模様の堅い冷たい感じがなくなり、自然感が付与される。なお凸ブロック(5) の平滑表面には微細凹凸模様を形成してもよい。この侵蝕崩落様部分(5A)は該凸ブロック(5) の全部または一部について、位置および/または形状および/または侵蝕崩落状態(凹凸状態)が相互に異なるようにされている。更に該凸ブロック(5) の複数個の縦横配列からなる柄ユニットの複数種を設定し、該複数種の柄ユニットの凸ブロック(5) 配列様式はすべて共通しており、かつ柄ユニット相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の柄ユニットを適宜選択して建築板(1) 表面に縦および/または横に配列してもよい。このようにすれば柄の繰返し感がなくなって意匠の面白味は更に増す。通常該柄ユニットは3〜4種類設定される。また上記柄ユニットにおいて凸ブロック(5) 平滑表面に微細凹凸模様があるものとないものとが設定されてもよい。
【0018】
上記建築板(1) にあっては、所定の個所から縦方向に沿って切断して巾Wの短冊状板材(1A)を切出す場合がある。この短冊状板材(1A)は例えば外壁の角部において、出隅部材や入隅部材として使用される。上記短冊状板材(1A)の巾Wは図7に示すように例えばW=70mmとW=101mmの2種あり、70mm巾の板材(1A)の場合には切断線Cでカットし、101mmの板材(1A)の場合は切断線Cでカットする。図7に示す場合は、建築板(1) の左端から巾WまたはWの短冊状板材(1A)を逐次切出す場合であり、右端部では巾MまたはMの端切れが出来る。
上記短冊状板材(1A)にあっては、図5に示すように切断線Cが凸ブロック(5) の上面縦辺Eに接近して通ると、切断線Cに沿う板材(1A)側縁部(図5ではC−E間S)の強度が弱くなって欠け易くなる。したがって図6に示すようにC−E間Sをある程度大きく確保することが望ましい。一般にS≧15mmとすれば板材(1A)側縁部の強度が充分確保出来る。
【0019】
しかしブロック調模様、特に小さいサイズの凸ブロック(5) が縦横に多数ランダムに配列されているようなブロック調模様を有する建築板(1) ではこのような条件を充たす位置に切断線Cを設定することが困難で、例えば長さ890mm、縦巾210mmの建築板(1) から巾W=70mmあるいはW=101mmの短冊状板材(1A)を切り出す場合、短冊状板材(1A)の両側の切断線Cが上記条件を充たすようにしようとすると、一枚の建築板(1) からせいぜい4枚程度しか切り出せない。
【0020】
そこで本実施例では、図7に示すように、長さ890mm、縦巾210mmの該建築板(1) の長手方向両端縁は各段の凸ブロック(5) の縦辺より15mm離れるように設定し、かつ巾Wの短冊状板材(1A)を6枚切り出せるように各段の凸ブロック(5) および縦凹溝(3) を配置した。具体的には図7において切断線Cは巾W=70mmの短冊状板材(1A)を切り出す場合、切断線Cは巾101mmの短冊状板材(1A)を切り出す場合であり、短冊状板材(1A)の切り出し間隔は巾W=70mmの該板材(1A)では78.3mm(a)、巾W=101mmの該板材(1A)では47.3mm(a)に設定される。そして切断線C,Cは各段の凸ブロック(5) の上面縦辺Eから15mm離れている。
【0021】
本実施例のように、建築板(1) の一端から所定巾Wの短冊状板材(1A)を切り出す時、一定の間隔(aまたはa)ごとに該短冊状板材(1A)を切り出せるように各段の凸ブロック(5) および縦凹溝(3) の配置を考慮すると、該板材(1A)切り出しの際の切断線Cの位置決定が容易になる。
【0022】
更に本発明では前記のように凸ブロック(5) の平滑な表面に微細凹凸模様を設けてもよいが、この微細凹凸模様は建築板(1) の凸ブロック(5) の全部に設けても一部に設けてもよい。
また前記の建築板(1) を複数種準備し、該複数種の建築板(1) の表面に配列されている凸ブロック(5) の配列様式はすべて共通しており、かつ該建築板(1) 相互の同位置にある凸ブロック(5) の平滑表面の侵蝕崩落様部分(5A)の位置および/または形状および/または侵蝕崩落状態は全体的または部分的に異ならしめられている複数種の建築板(1) を適宜選択して構築物躯体表面に縦および/または横に配列張設すれば、同種類の建築板(1) を張設した場合の柄の繰返し感がなくなり、変化に富んだ意匠の外壁等の構築物を構築することが出来る。この場合、該凸ブロック(5) の平滑表面に微細凹凸模様を付したものと付してないものとが設定されていてもよい。
【0023】
【発明の効果】
本発明の建築板にあっては、ブロック調の模様を有しながら変化に富み、そして規則的な堅い冷たさもなく、自然感あふれる好ましい意匠が付されることによって商品価値の高いものとなる。
