【発明の属する技術分野】
本発明は、熱媒体流通管を嵌合する溝部が形成された板状基材が、複数の矩形状の折り畳み単位部分に分離させて折り畳み可能に構成され、前記折り畳み単位部分の夫々には、前記溝部として、複数の折り畳み単位部分の並び方向と直交する方向に延びる直線溝部分と、その直線溝部分の端部から隣接する他の折り畳み単位部分側に湾曲する状態で延びる湾曲溝部分とが形成されて、前記複数の折り畳み単位部分を折り畳むときには、前記湾曲溝部分に嵌合される熱媒体流通管を離脱させるように構成されている床暖房パネルに関する。
【0002】
【従来の技術】
上記のような床暖房パネルは、暖房対象となる床の面積に合わせて並べる折り畳み単位部分の枚数を適宜し、床暖房パネルを折り畳み単位部分で折り畳み可能に構成することにより、床の面積に合わせた大きさの床暖房パネルを構成しながら、折り畳み単位部分で折り畳んで、運搬などの各種の作業を容易に行うようにしているものである。
【0003】
本出願人は、上述のように、折り畳み単位部分で折り畳み可能な床暖房パネルを先に出願している(特願2001−160091号参照)。
本出願人が先に出願した床暖房パネルについて説明を加えると、溝部に熱媒体流通管を嵌合させた状態で板状基材の表面側にアルミ箔などの表面材を貼着して板状基材の全体を一体化させたのち、湾曲溝部分に貼着された表面材を剥して、湾曲溝部分に嵌合された熱媒体流通管を露出させるとともに、表面材を折り畳み単位ごとに分離させることによって、熱媒体流通管を湾曲溝部分から離脱可能にした状態で、板状基材を複数の折り畳み単位に分離させるように構成されている。
そして、複数の折り畳み単位を折り畳むときには、熱媒体流通管を湾曲溝部分から離脱させて、その離脱された熱媒体流通管を間に挟む状態で折り畳み単位部分どうしを互いに密着させて折り畳むように構成されている。
また、上記の床暖房パネルでは、湾曲溝部分の溝幅が、熱媒体流通管の外径とほぼ同じになるように構成されている。
【0004】
このように構成された床暖房パネルは、熱媒体流通管を湾曲溝部分から離脱させて折り畳んだ状態に組み立てられ、その組み立てられた状態で施工現場まで運搬される。
そして、施工現場では、折り畳んだ床暖房パネルを広げて、暖房対象の床面に敷設し、折り畳むために湾曲溝部分から離脱させた熱媒体流通管を湾曲溝部分に嵌合させたのち、湾曲溝部分の上面側を覆うように表面材を貼着させて、暖房対象の床に対する施工を行うようにしている。
【0005】
ちなみに、上記の床暖房パネルでは、複数の折り畳み単位を折り畳むときに、湾曲溝部分から熱媒体流通管を離脱させて折り畳むことにより、付属部品点数の減少を図り、梱包作業の容易化を図るようにしている。
【0006】
【発明が解決しようとする課題】
上記の床暖房パネルでは、例えば、夏期に床暖房パネルを組み立て、冬期に暖房対象の床に対して施工することがあり、このような場合には、外気温の変化により、熱媒体流通管が収縮することになる。
したがって、湾曲溝部分の溝幅が、熱媒体流通管の外径とほぼ同じになるように構成されている上記の床暖房パネルでは、施工現場で、折り畳むために湾曲溝部分から離脱させた熱媒体流通管を湾曲溝部分に嵌合させることができなかったり、離脱させた熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うために時間やコストがかかることになる。
【0007】
本発明は、かかる点に着目してなされたものであり、その目的は、施工現場で、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、熱媒体流通管を湾曲溝部分に嵌合させて、施工作業の時間短縮およびコストの低減を図ることが可能となる床暖房パネルを提供する点にある。
【0008】
【課題を解決するための手段】
この目的を達成するために、請求項1に記載の発明によれば、熱媒体流通管を嵌合する溝部が形成された板状基材が、複数の矩形状の折り畳み単位部分に分離させて折り畳み可能に構成され、前記折り畳み単位部分の夫々には、前記溝部として、複数の折り畳み単位部分の並び方向と直交する方向に延びる直線溝部分と、その直線溝部分の端部から隣接する他の折り畳み単位部分側に湾曲する状態で延びる湾曲溝部分とが形成されて、前記複数の折り畳み単位部分を折り畳むときには、前記湾曲溝部分に嵌合される熱媒体流通管を離脱させるように構成されている床暖房パネルにおいて、
前記湾曲溝部分の溝幅が、前記熱媒体流通管の外径よりも大きくなるように構成されている。
【0009】
すなわち、湾曲溝部分の溝幅を、熱媒体流通管の外径よりも大きくなるように構成することにより、床暖房パネルを組み立てるときには、その組み立てる時期に応じて、湾曲溝部分の溝幅方向での熱媒体流通管の嵌合位置を選定して、熱媒体流通管を湾曲溝部分に嵌合させることができることになる。
したがって、組立時期に応じて、湾曲溝部分の溝幅方向での熱媒体流通管の嵌合位置を選定して組み立てられた床暖房パネルを暖房対象の床に対して施工するときには、熱媒体流通管が収縮または伸長しても、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、湾曲溝部分から離脱させた熱媒体流通管を、熱媒体流通管の湾曲溝部分に対して嵌合させることができることになる。
【0010】
説明を加えると、例えば、夏期に床暖房パネルを組み立て、冬期にその床暖房パネルを暖房対象の床に施工する場合には、湾曲溝部分の内周側と間隔を隔てる状態となるように、湾曲溝部分の溝幅方向での熱媒体流通管の嵌合位置を選定して床暖房パネルを組み立てることができ、このようにして組み立てられた床暖房パネルを、冬期に暖房対象の床に対して施工するときには、外気温の変化により、熱媒体流通管が収縮しても、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、湾曲溝部分から離脱させた熱媒体流通管を、熱媒体流通管の湾曲溝部分に対して嵌合させることができることになる。
また、冬期に床暖房パネルを組み立て、夏期にその床暖房パネルを暖房対象の床に施工する場合には、湾曲溝部分の外周側と間隔を隔てる状態となるように、湾曲溝部分の溝幅方向での熱媒体流通管の嵌合位置を選定して床暖房パネルを組み立てることができ、このようにして床暖房パネルを、夏期に暖房対象の床に対して施工するときには、外気温の変化により、熱媒体流通管が伸長しても、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、湾曲溝部分から離脱させた熱媒体流通管を、熱媒体流通管の湾曲溝部分に対して嵌合させることができることになる。
【0011】
以上のことより、外気温の変化により、床暖房パネルを組み立てたときよりも、熱媒体流通管が収縮または伸長しても、施工現場では、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、湾曲溝部分から離脱させた熱媒体流通管を、湾曲溝部分に対して嵌合させることが可能となる。
したがって、施工現場で、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、熱媒体流通管を湾曲溝部分に嵌合させて、施工作業の時間短縮およびコストの低減を図ることが可能となる
又、湾曲溝部分から離脱された熱媒体流通管の湾曲半径が大になるようにした状態で、折り畳み単位部分どうしを互いに密着させるように折り畳んで梱包することにより、湾曲溝部分から離脱された熱媒体流通管の湾曲半径を、折り畳んだときに熱媒体流通管の座屈が防止できるような湾曲半径とした状態で、折り畳み単位部分どうしを互いに密着させるように折り畳んで梱包することになる。
したがって、熱媒体流通管の湾曲半径を、熱媒体流通管の座屈を防止可能な湾曲半径とした状態で、折り畳み単位部分どうしを互いに密着させるように折り畳んで梱包することにより、熱媒体流通管の座屈を防止しながら、折り畳んだ複数の折り畳み単位部分の厚みが薄くなるように折り畳んで梱包することができることになる。
以上のことから、折り畳んだ複数の折り畳み単位部分を、その折り畳んだ状態でダンボールなどに梱包することによって、施工現場で、熱媒体流通管を湾曲溝部分に嵌合させるための手直し作業を行うことなく、熱媒体流通管を湾曲溝部分に嵌合させて、施工作業の時間短縮およびコストの低減を図ることが可能となり、しかも、熱媒体流通管の損傷を防止し、かつ、コンパクトに梱包する床暖房パネルの梱包方法を提供できるに至った。
【0012】
請求項2に記載の発明によれば、前記折り畳み単位部分の夫々には、複数の折り畳み単位部分の並び方向に沿って並ぶ状態で複数の前記直線溝部分が設けられ、かつ、複数の折り畳み単位部分の並び方向と直交する方向に沿って並ぶ状態で、複数の前記直線溝部分の夫々から各別に連なる複数の前記湾曲溝部分が設けられている。
【0013】
すなわち、折り畳み単位部分の夫々に、複数の直線溝部分を設けるとともに、それら複数の直線溝部分の夫々から各別に連なる複数の湾曲溝部分を設ける構成とすることにより、複数の折り畳み単位部分の並び方向に隣接する熱媒体流通管どうしの間に間隔を隔てる状態で熱媒体流通管を直線溝部分に嵌合させ、複数の折り畳み単位部分の並び方向と直交する方向に隣接する熱媒体流通管どうしの間に間隔を隔てる状態で熱媒体流通管を湾曲溝部分に嵌合させることができることになる。
【0014】
したがって、複数の折り畳み単位部分の並び方向および複数の折り畳み単位部分の並び方向と直交する方向のいずれの方向にも、熱媒体流通管を分散させる状態で、複数の折り畳み単位の夫々に熱媒体流通管を備えさせることができ、熱媒体流通管に熱媒を通流させることにより、複数の折り畳み単位部分の夫々において、温度分布を均一にさせて、床暖房パネルの全体にわたって均一に暖房することが可能となる。
【0015】
請求項3に記載の発明によれば、前記板状基材が、前記複数の直線溝部分が形成された直線用基材部分と、前記複数の湾曲溝部分が形成された湾曲用基材部分とを並べて構成されている。
【0016】
すなわち、板状基材を、直線用基材部分と湾曲用基材部分とを並べて構成することにより、直線用基材部分と湾曲用基材部分との2種類を、枚数および組み合せ方を適宜変更させて、床暖房パネルを組み立てることによって、暖房対象の床形状および床面積の大きさに対応した床暖房パネルを組み立てることができることになる。
したがって、直線用基材部分と湾曲用基材部分の2種類を組み合わせて、暖房対象の床形状および床面積の大きさに対応した床暖房パネルを組み立てることができ、コストの低減を図りながら、所望の床暖房パネルを構成することが可能となる。
【0024】
【発明の実施の形態】
本発明にかかる床暖房パネルについて図面に基づいて説明する。
この床暖房パネルPは、図1および図2に示すように、板状基材3の溝部2に熱媒体流通管1を嵌合させた状態で、複数の基材部分の表面側に表面材としてのアルミ箔5を貼着させて構成されている。
そして、板状基材3は、図7〜図9に示すように、折り畳み線A, Bに沿って複数の矩形状の折り畳み単位部分10に分離させて折り畳み可能に構成されている。
なお、図1は、アルミ箔5を外した状態での床暖房パネルPを示している。
【0025】
前記板状基材3は、複数の直線溝部分2aが形成された矩形状の直線用基材部分6と、複数の端部湾曲溝部分2bが形成された矩形状の端部湾曲用基材部分7と、複数の湾曲溝部分2cが形成された矩形状の湾曲用基材部分8とを並べて構成されている。
そして、複数の折り畳み単位部分10の並び方向(図1中X方向)を同一方向として、隣接させるものの間に長尺で幅広の木製の小根太9を位置させる状態で、複数の直線用基材部分6を並置し、複数の折り畳み単位部分10の並び方向に直交する方向(図1中Y方向)の端部に、端部湾曲用基材部分7または湾曲用基材部分8を配置して構成されている。
また、端部湾曲用基材部分7および湾曲用基材部分8の夫々には、小根太装着部11が形成され、その小根太装着部11の夫々に、上述の小根太9および矩形状の木製の小根太9aを装着するように構成されている。
【0026】
前記直線用基材部分6の夫々は、厚みと幅がほぼ同一に構成され、端部湾曲用基材部分7および湾曲用基材部分8の夫々は、厚みと幅が直線用基材部分6とほぼ同じ厚みおよびほぼ同じ幅に構成されている。
ちなみに、端部湾曲用基材部分7および湾曲用基材部分8の幅については、直線用基材部分6の幅に対して倍数となる幅であればよいので、直線用基材部分6の幅に対してほぼ2倍、3倍、4倍、または、5倍以上の幅にしてもよく、直線用基材部分6の枚数に応じて適宜変更することも可能である。
【0027】
前記直線溝部分2aは、溝部2として、複数の折り畳み単位部分10の並び方向と直交する方向に延びるように形成されて、複数の折り畳み単位部分10の並び方向に沿って並ぶ状態で直線基材部分6に複数形成されている。
前記端部湾曲溝部分2bは、溝部2として、直線溝部分2aの端部から複数の折り畳み単位部分10の並び方向に隣接する他の直線用基材部分6側に湾曲する状態で延びるように形成されて、複数の折り畳み単位部分10の並び方向と直交する方向に沿って並ぶ状態で、複数の直線溝部分2aの夫々から各別に連なるように端部湾曲用基材部分7に複数形成されている。
【0028】
ちなみに、複数の折り畳み単位10の並び方向の端部以外の箇所に配置された端部湾曲用基材部分7の端部湾曲溝部分2bは、直線用基材部分6の直線溝部分2aから、複数の折り畳み単位部分10の並び方向に隣接する他の直線用基材部分6の直線溝部分2a5にわたって熱媒体流通管1を嵌合するように形成され、複数の折り畳み単位10の並び方向の端部に配置された端部湾曲用基材部分7の端部湾曲溝部分2bは、同一の直線用基材部分6の直線溝部分2a間で熱媒体流通管1を嵌合するように形成されている。
また、直線溝部分2aおよび端部湾曲溝部分2bは、その溝幅が熱媒体流通管1の外径とほぼ同じ大きさになるように形成されている。
【0029】
また、湾曲溝部分2cは、溝部2として、直線溝部分2aの端部から複数の折り畳み単位部分10の並び方向に隣接する他の折り畳み単位部分10側に湾曲する状態で延びるように形成されて、複数の折り畳み単位部分10の並び方向と直交する方向に沿って並ぶ状態で、複数の直線溝部分2aの夫々から各別に連なるように湾曲用基材部分8に複数形成されている。
そして、湾曲溝部分2cの溝幅は、熱媒体流通管1の外径よりも大きくなるように構成され、湾曲溝部分2cのうち、複数の折り畳み単位部分10の並び方向に沿う状態から、複数の折り畳み単位部分10の並び方向に直交する方向に沿う状態に湾曲する湾曲部2Cが、熱媒体流通管1の嵌合位置をその溝幅方向に移動可能に構成されている。
【0030】
前記直線用基材部分6、端部湾曲用基材部分7、および、湾曲基材部分8は、断熱作用を有して軽量化が可能な樹脂製(例えば、硬質のポリスチレン発泡体など)の板状体から構成され、その板状体に、パネル表面側を開口している上向き凹状の直線溝部分2a、端部湾曲溝部分2bおよび湾曲溝部分2cなどの溝部2が形成されている。
【0031】
前記熱媒体流通管1は、一般的に架橋ポリエチレン管やポリブテン樹脂管など可撓性のあるものが使用され、図1に示すように、接続部のない2本の熱媒体流通管1から構成され、2本の熱媒体流通管1を、直線溝部分2a、端部湾曲溝部分2b、湾曲溝部分2cにわたって1本ずつ嵌合させるように構成されている。
【0032】
前記2本の熱媒体流通管1の両端は、幅広の端部湾曲用基材部分7aのひとつに設けられている熱媒体供給部12に接続され、図外の熱源機から温水などの熱媒体が熱媒体供給部12の往き側を介して熱媒体流通管1の夫々に供給されるように構成され、熱媒体流通管1に供給された温水が、熱媒体流通管1を通流して熱媒体供給部12の戻り側を介して床暖房パネルPから排出するように構成されている。
すなわち、直線溝部分2a、端部湾曲溝部分2b、湾曲溝部分2cにわたって嵌合されている熱媒体流通管1に、熱媒体供給部12を介して図外の熱源機からの温水を通流させることにより暖房対象の床が暖房されるように構成されている。
ちなみに、熱媒体流通管1は、往き側のものと戻り側のものとが互いに隣接するように配管されている。
【0033】
そして、上述のような床暖房パネルPの組み立て構成について説明を加えると、図6に示すように、湾曲溝部分2cに対しては、熱媒体流通管1が収縮しても嵌合できるように、湾曲溝部分2cの外周側に沿わせる状態で熱媒体流通管1を嵌合させるとともに、直線溝部分2aおよび端部湾曲溝部分2bにも熱媒体流通管1を嵌合させるようにしている。
そして、溝部2に熱媒体流通管1を嵌合させた状態で、板状基材3の表面側にアルミ箔5を貼着することにより、直線用基材部分6、端部湾曲用基材部分7、湾曲基材部分8、および、小根太9を接続して、直線用基材部分6、端部湾曲用基材部分7、湾曲基材部分8、および、小根太9を一体化させて、ひとつの床暖房パネルPが構成されている。
【0034】
上述のような床暖房パネルPは、暖房対象である床面積に応じて、直線用基材部分6と端部湾曲用基材部分7の枚数を適宜変更して、その大きさを変更するように構成されているが、運搬などの容易化を図るために床暖房パネルPを複数の折り畳み単位10で折り畳み可能に構成されている。
そして、複数の折り畳み単位部分10を折り畳むときには、湾曲溝部分2cに嵌合される熱媒体流通管1を離脱させて、複数の折り畳み単位部分10を折り畳むように構成されている。
【0035】
すなわち、この実施形態では、複数の折り畳み単位部分10の並び方向に隣接する3つの直線用基材部分6と、複数の折り畳み単位部分10の並び方向に直交する方向の両端部に配置されている端部湾曲用基材部分7および湾曲用基材部分8とを、ひとつの折り畳み単位部分10として構成し、全体として3枚の折り畳み単位部分10を並べて構成されている。
そして、折り畳み単位部分10の隣接箇所である直線用基材部分6の長さ方向に沿う折り畳み線A,Bに沿って、床暖房パネルPを2箇所で折り畳み可能に構成されている。
【0036】
説明を加えると、図7に示すように、湾曲用基材部分8の表面側に貼着されたアルミ箔5を取り外して、図8に示すように、複数の折り畳み単位部分10の並び方向に隣接する湾曲用基材部分8を、折り畳み線A,Bに沿って分離させるとともに、折り畳み線A,Bに沿ってアルミ箔5を分離させて、板状基材3を3枚の折り畳み単位部分10に分離させるように構成されている。
そして、図9に示すように、湾曲用基材部分8の湾曲溝部分2cに嵌合されている熱媒体流通管1を取り外し、折り畳み単位部分10を距離Qだけずらして、熱媒体流通管1の座屈を防止できる最小曲げ半径を確保しながら、複数の折り畳み単位部分10を折り畳むように構成されている。
【0037】
上述のようにして組み立てられた床暖房パネルPは、折り畳んだ状態で施工現場に運搬され、その施工現場で、床暖房パネルPを広げて、折り畳むために湾曲溝部分2cから離脱させた熱媒体流通管1を、熱媒体流通管1の外径よりも大きな溝幅の湾曲溝部分2cに対して嵌合させて、湾曲基材部分8の上面にもアルミ箔5を貼着させるように構成されている。
【0038】
このようにして、湾曲溝部分2cの溝幅を熱媒体流通管1の外径よりも大きくなるように構成することにより、湾曲溝部分2cの外周側に沿わせる状態となるように、湾曲溝部分2cの溝幅方向での熱媒体流通管1の嵌合位置を選定して、熱媒体流通管1を湾曲溝部分2cに嵌合させて、外気温の変化により、床暖房パネルPを組み立てたときよりも、熱媒体流通管1が収縮しても、施工現場では、熱媒体流通管1を湾曲溝部分2cに嵌合させるための手直し作業を行うことなく、湾曲溝部分2cから離脱させた熱媒体流通管1を、湾曲溝部分2cに対して嵌合させて、施工作業の時間短縮およびコストの低減を図るようにしている。
【0039】
上述のような床暖房パネルPの製造方法において、夏期に床暖房パネルを製造するときの製造方法について説明を加える。
まず、暖房対象である床面積に応じて、直線用基材部分6と端部湾曲用基材部分7の枚数を決定し、図1に示すように、直線用基材部分6、端部湾曲用基材部分7、小根太9、および、湾曲用基材部分8を並置する。
そして、図3に示すように、湾曲用基材部分8と直線用基材部分6との間に、例えば、厚みが10mmの直方体状の間隔保持部材13を介在させて、湾曲用基材部分8と直線用基材部分6とを間隔を隔てた状態で並置させる。
その状態で、図4に示すように、直線溝部分2aおよび端部湾曲溝部分2bに熱媒体流通管1を嵌合させるとともに、湾曲溝部分2cに対して、熱媒体流通管1を湾曲溝部分2cの内周側に沿わせて嵌合させる。
【0040】
その後、図5に示すように、間隔保持部材13を取り外し、図6に示すように、湾曲用基材部分8を直線基材部分6に当接させることにより、湾曲溝部分2cの内周側に沿わせて嵌合された熱媒体流通管1をその外周側に移動させて、湾曲溝部分2cの外周側に沿わせる状態で熱媒体流通管1を湾曲溝部分2cに嵌合させる。
このようにして、溝部2に熱媒体流通管1が嵌合された状態で、直線用基材部分6、端部湾曲用基材部分7、湾曲基材部分8、および、小根太9の表面側にアルミ箔5を貼着して、直線用基材部分6、端部湾曲用基材部分7、湾曲基材部分8、および、小根太9を一体化させて、ひとつの床暖房パネルPを製造するようにしている。
【0041】
ちなみに、間隔保持部材13の厚みおよび湾曲溝部分2cの溝幅は、湾曲用基材部分8と直線用基材部分6との間に隔保持部材13を介在させて、熱媒体流通管1を湾曲溝部分2cの内周側に沿わせて嵌合させたのち、間隔保持部材13を取り外して湾曲用基材部分8を直線基材部分6に当接させることにより、湾曲溝部分2cの外周側に沿わせる状態で熱媒体流通管1を湾曲溝部分2cに嵌合させるように調整されている。
【0042】
上述のような床暖房パネルの梱包方法について説明を加える。
上述のようにして製造された床暖房パネルPは、図7に示すように、湾曲用基材部分8の表面側に貼着されたアルミ箔5を取り外して、図8に示すように、湾曲用基材部分8を、折り畳み線A,Bに沿って分離させるとともに、折り畳み線A,Bに沿ってアルミ箔5を分離させて、板状基材3を3枚の折り畳み単位部分10に分離させる。
ちなみに、湾曲用基材部分8以外の部分は、上面にアルミ箔5を貼り付けることにより連結され、分離された湾曲用基材部分8の夫々は、板状基材3の裏面に粘着テープなどを貼って、複数の折り畳み単位部分10の並び方向に隣接する端部湾曲用基材部分7に連結され、板状基材3を3枚の折り畳み単位部分10に分離させるようにしている。
【0043】
そして、図9の(イ)に示すように、湾曲溝部分2cに嵌合された熱媒体流通管1を湾曲溝部分2cから取り外し、図9の(ロ)、および、図10に示すように、取り外された熱媒体流通管1の湾曲半径が大になるように折り畳み単位部分10どうしを折り畳み単位部分10の辺に沿って距離Qだけずらした状態で、折り畳み単位部分10どうしを互いに密着させるように折り畳むようにしている。
なお、距離Qは、図10に示すように、敷設した状態での直線溝部分2a間の距離D以上に設定されており、最小曲げ半径(通常、4.5×熱媒体流通管1の外形寸法)を確保しながら、床暖房パネルPを折り畳むようにしている。
【0044】
また、折り畳み単位部分10を折り畳むときには、湾曲溝部分2cから取り外した熱媒体流通管1を間に挟む状態で折り畳み単位部分10どうしを互いに密着させるように折り畳み、図9の(ハ)および(二)に示すように、折り畳んだ折り畳み単位部分10の側部に、平面視において、折り畳み単位部分10の重複部分からはみ出る熱媒体流通管1を収納する緩衝部材14を取り付けて、熱媒体流通管6を露出させることなく、熱媒体流通管6の損傷を防止するようにしている。
なお、図9の(ニ)は、折り畳んだ折り畳み単位部分10の側部に、緩衝部材10を取り付けた状態での側面図を示している。
【0045】
前記緩衝部材14は、角筒状のもので形成され、一側面部に熱媒体流通管1を収納するための開口14aが形成され、その開口部14aが形成された側面部を折り畳んだ折り畳み単位部分10の側部に密着させることによって、熱媒体流通管1を緩衝部材14に収納させるようにしている。
【0046】
そして、図11に示すように、3枚の折り畳み単位部分10を互い違いに距離Qだけずらしながら折り畳み、そのずらした距離Qを維持するように、図12に示すように、ずらした方向の両端を姿勢維持用のスペーサー15を介在させて段ボール箱16内に収納して梱包するようにしている。
【0047】
〔別実施形態〕
(1)上記実施形態では、湾曲溝部分2cの一部である湾曲部2cのみ、その溝幅を熱媒体流通管1の外径よりも大きくなるように構成されているが、湾曲溝部分2cの全長にわたって、その溝幅を熱媒体流通管1の外径よりも大きくなるように構成することも可能であり、湾曲溝部分2cにおいて、溝幅を熱媒体流通管1の外径よりも大きくする部分の長さについては適宜変更が可能である。
【0048】
(2)上記実施形態では、折り畳み単位部分10の夫々に、複数の直線溝部分2aおよび複数の湾曲溝部分2cを設けるようにしているが、直線溝部分2aおよび湾曲溝部分2cの数については適宜変更が可能であり、熱媒体流通管1を1本ずつ直線溝部分2aおよび湾曲溝部分2cに嵌合させるものであればよい。
【0049】

In the above-mentioned floor heating panel, for example, the floor heating panel may be assembled in the summer and applied to the floor to be heated in the winter. In such a case, the heat medium distribution pipe is caused by a change in the outside air temperature. Will contract.
Therefore, in the above floor heating panel configured such that the groove width of the curved groove portion is substantially the same as the outer diameter of the heat medium flow pipe, the heat removed from the curved groove portion for folding at the construction site is provided. It is not possible to fit the medium flow tube into the curved groove portion, and it takes time and cost to perform a rework operation for fitting the detached heat medium flow tube into the curved groove portion.
[0007]
The present invention has been made paying attention to such a point, and its purpose is to perform the heat medium circulation pipe on the construction site without performing a reworking operation for fitting the heat medium circulation pipe to the curved groove portion. The object of the present invention is to provide a floor heating panel that can be fitted into the curved groove portion to shorten the construction work time and reduce the cost.
[0008]
[Means for Solving the Problems]
In order to achieve this object, according to the first aspect of the present invention, the plate-like base material on which the groove for fitting the heat medium flow pipe is formed is separated into a plurality of rectangular folding unit portions. Each of the foldable unit portions is configured to be foldable, and each of the foldable unit portions includes, as the groove portion, a linear groove portion that extends in a direction orthogonal to the direction in which the plurality of foldable unit portions are arranged, A bending groove portion extending in a state of being bent toward the folding unit portion side is formed, and when the plurality of folding unit portions are folded, the heat medium circulation pipe fitted to the bending groove portion is configured to be detached. Floor heating panel
The groove width of the curved groove portion is configured to be larger than the outer diameter of the heat medium flow pipe.
[0009]
That is, by assembling the floor heating panel by configuring the groove width of the curved groove portion to be larger than the outer diameter of the heat medium flow pipe, the groove width direction of the curved groove portion depends on the time of assembly. By selecting the fitting position of the heat medium flow pipe, the heat medium flow pipe can be fitted into the curved groove portion.
Therefore, when the floor heating panel assembled by selecting the fitting position of the heat medium flow pipe in the groove width direction of the curved groove portion according to the assembly time is applied to the floor to be heated, the heat medium flow Even if the pipe contracts or expands, the heat medium flow pipe removed from the curved groove part is not subjected to the reworking work for fitting the heat medium flow pipe to the curved groove part. It can be made to fit with respect to a part.
[0010]
For example, when assembling a floor heating panel in the summer and constructing the floor heating panel on the floor to be heated in the winter, for example, the space is separated from the inner peripheral side of the curved groove portion. The floor heating panel can be assembled by selecting the fitting position of the heat medium flow pipe in the groove width direction of the curved groove part, and the floor heating panel assembled in this way can be attached to the floor to be heated in winter Even if the heat medium flow tube contracts due to changes in the outside air temperature, the heat removed from the curved groove portion is not necessary without performing a rework operation for fitting the heat medium flow tube to the curved groove portion. The medium flow pipe can be fitted to the curved groove portion of the heat medium flow pipe.
In addition, when a floor heating panel is assembled in the winter, and the floor heating panel is installed on the floor to be heated in the summer, the groove width of the curved groove portion is separated from the outer peripheral side of the curved groove portion. The floor heating panel can be assembled by selecting the fitting position of the heat medium flow pipe in the direction, and when the floor heating panel is constructed on the floor to be heated in this way, the change of the outside temperature Thus, even if the heat medium flow tube is extended, the heat medium flow tube removed from the curved groove portion without performing the reworking operation for fitting the heat medium flow tube to the curved groove portion. This can be fitted to the curved groove portion.
[0011]
  From the above, even when the heat medium flow pipe contracts or expands more than when the floor heating panel is assembled due to changes in the outside air temperature, the heat medium flow pipe is fitted to the curved groove portion at the construction site. It is possible to fit the heat medium flow pipe detached from the curved groove portion to the curved groove portion without performing the reworking operation.
  Therefore, at the construction site, the heat medium flow pipe is fitted to the curved groove portion without performing a rework work for fitting the heat medium flow pipe to the curved groove portion, thereby shortening the construction work time and cost. It becomes possible to plan.
In addition, in the state where the bending radius of the heat medium flow pipe separated from the curved groove portion is increased, the folding unit portions are folded and packed so as to be in close contact with each other, thereby being detached from the curved groove portion. In the state in which the curvature radius of the heat medium circulation pipe is set to a curvature radius that can prevent buckling of the heat medium circulation pipe when folded, the folding unit parts are folded and packed so as to be in close contact with each other.
Therefore, the heat medium flow pipe is folded and packed so that the folding unit portions are in close contact with each other in a state in which the heat medium flow pipe has a curved radius that can prevent buckling of the heat medium flow pipe. Thus, it can be folded and packed so that the thickness of the plurality of folded unit parts is reduced.
From the above, by carrying out the reworking work to fit the heat medium flow pipe into the curved groove part at the construction site by packing a plurality of folded folding unit parts into a corrugated cardboard in the folded state. In addition, it is possible to reduce the construction work time and cost by fitting the heat medium flow pipe into the curved groove portion, and to prevent the heat medium flow pipe from being damaged and to pack it in a compact manner. It came to be able to provide the packing method of the floor heating panel.
[0012]

A plurality of the curved groove portions that are continuously provided from each of the plurality of straight groove portions are provided in a state of being arranged along a direction orthogonal to the arrangement direction of the portions.
[0013]

The heat medium flow pipes are fitted into the straight groove portions with a space between the heat medium flow pipes adjacent to each other in the direction, and the heat medium flow pipes adjacent to each other in the direction orthogonal to the arrangement direction of the plurality of folding unit portions. Thus, the heat medium flow pipe can be fitted into the curved groove portion with a space therebetween.
[0014]
