Description

【0001】
【発明の属する技術分野】
本発明は床暖房用パネルユニット及びそれを用いた床暖房用パネルに関するものである。
【0002】
【従来の技術】
近来、熱媒循環用パイプを設けたパネルユニットの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成することが提案されている。
例えば、本出願人の先の出願、特願平8−242855号の願書に添付した明細書及び図面に示すものでは、各パネルユニットは、図18、図19に示すように正方形の板状体aの4隅に切欠部bを設け、切欠部bの近傍下側に支持脚c(◎で位置を表示)を設置すると共に、熱媒循環用パイプdを蛇行させて1経路構成し、この熱媒循環用パイプdの両端部を一隅の切欠部bに位置させた構成である。このパネルユニットeでは、切欠部bの形状は、隅を直角に切り欠いた正方形の形状としている。
【0003】
この構成において、各パネルユニットeを、熱媒循環用パイプdの両端部が位置する夫々の一隅を対向させるように4つを1群として隣接すると、それらの切欠部bにより、切欠部の4倍の大きさの正方形状の空間部fが構成され、この空間部fにおいて、夫々の熱媒循環用パイプdの端部を熱源装置に連なる熱媒往き管、熱媒還り管のヘッダーh等の管継手構造の供給用部材に接続して、温水を循環供給させるようにしたり、隣接のパネルユニットeを帯板状金具等の接続用部材gにより接合する。
この後、空間部fを塞ぐために、パネルユニットeの、少なくとも上側に捨貼合板iを積層し、その上側にフローリング床等の仕上床材jを積層して床を構成している。
【0004】
以上の構成において、熱媒循環用パイプdの経路は、板状体aに形成した溝(図示省略)に熱媒循環用パイプdを装着して構成し、その後、切欠部bに位置する熱媒循環用パイプdの端部に上記供給用部材を接続している。溝は熱媒循環用パイプdを確実に装着するために遊びのない構成としている。
また本発明者等による他の発明においては、各パネルユニットに複数の熱媒循環用パイプの経路を構成して、各熱媒循環用パイプの端部を夫々の切欠部に位置させ、上記空間部において、同じパネルユニットの熱媒循環用パイプの端部間又は隣接するパネルユニットの熱媒循環用パイプの端部間を管継手構造の接続用部材により接続して適宜の直列経路を構成するようにしている。
【0005】
【発明が解決しようとする課題】
熱媒循環用パイプを溝に装着して経路を構成する際には、必ずしも全て同一の状態で装着することはできないので、熱媒循環用パイプの端部の位置が所定の位置よりもずれてしまうことがある。しかしながら、溝は熱媒循環用パイプを遊びなく装着するように構成しているので、熱媒循環用パイプの端部の位置を調整することはできない。このため、上記管継手構造の供給用部材や接続用部材の接続が困難となる場合がある。
本発明では、このような課題を解決することを目的とするものである。
【0006】
【課題を解決するための手段】
上述した課題を解決するために、本発明では、まず、切欠部を設けた板状体に熱媒循環用パイプの経路を設けて成るパネルユニットの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成すると共に、隣接する切欠部により空間部を構成するものにおいて、上記経路は、板状体に形成した溝に熱媒循環用パイプを装着して構成すると共に、上記経路の端部を切欠部に位置させる構成とし、前記切欠部の端縁から内側に低段部を構成すると共に、経路を構成する溝は、この低段部に対応する経路の端部近傍において切欠部方向に低くなる傾斜部を構成し、経路の曲がり部において熱媒循環用パイプの外径よりも幅広に構成すると共に、経路の端部近傍において切欠部方向に末広がりに構成した床暖房用パネルユニットを提案する。
【0007】
本発明では、以上の構成において、熱媒循環用パイプの外径よりも幅広に構成する経路の曲がり部は、経路の端部から1回目の曲がり部のみとすることを提案する。
【0008】
本発明では、以上の構成において、切欠部は、板状体の隅や、辺の中央部に設けることができる。
【0009】
また本発明において切欠部は、板状体を斜めに切り欠いた直角二等辺三角形状に構成したり、方形状に構成することができる。
【0010】
また本発明では、上述した切欠部の端縁から内側に低段部を構成すると共に、経路を構成する溝は、この低段部に対応する経路の端部近傍において切欠部方向に低くなる傾斜部を構成する床暖房用パネルユニットの複数を縦横に隣接させると共に隣接する切欠部により空間部を構成し、この空間部において所望の他の経路の熱媒循環用パイプの端部相互間を接続用部材により接続すると共に、所望の経路の熱媒循環用パイプの端部に熱媒の供給 用部材を接続し、更に空間部の周囲に形成される低段部に、その深さと同じ厚さの接合板を嵌合し、接合板を各パネルユニットに固定することにより隣接するパネルユニットを接合する構成の床暖房用パネルを提案する。
【0011】
そして本発明では、以上の構成において、床暖房用パネルユニットは、支持脚を備え、所定の高さに支持可能な構成とすることを提案する。
【0012】
以上の本発明によれば、熱媒循環用パイプの経路の曲がり部に対応する溝の部分に構成した幅広な遊びにより、熱媒循環用パイプの端部位置を、その長さ方向に調整することができる。
また熱媒循環用パイプの経路の端部近傍に対応する溝の部分に切欠部方向に構成した末広がりな構成の遊びにより、熱媒循環用パイプの端部位置を、横方向に調整することができる。
従って、前者又は後者のいずれか、又は両者を適用することにより、上述した管継手構造の供給用部材や接続用部材の接続が容易となる。
【0013】
【発明の実施の形態】
次に本発明の実施の形態を図を参照して説明する。まず、図1は本発明を適用するパネルユニットUの第1の実施の形態を示す平面図であり、図2は図1のA−A線断面図である。また、図3は図1のパネルユニットUの右上部分の拡大図、図4は図3のB−B線断面図である。また図5は、以上のパネルユニットの複数を縦横に隣接させて構成した床暖房用パネルの一部を模式的に示す平面図である。
符号1は板状体であり、この板状体1は正方形であって、各隅には、斜めに切り欠いた直角二等辺三角形状の切欠部2(2a,2b,2c,2d)を設けており、この切欠部2の端縁から内側に低段部7を構成している。
図2に示すように板状体1の上面には、隣接する切欠部2に夫々の端部が位置するように複数の溝4を形成しており、これらの夫々に熱媒循環用パイプ3を装着することにより、熱媒循環用パイプ3を4経路構成するものとしている。
即ち、熱媒循環用パイプ3は切欠部2a,2b;2b,2c;2c,2d;2d,2a間の溝4に夫々装着して、経路3a;3b;3c;3dの4経路構成していて、それらの経路の熱媒循環用パイプ3の両側の夫々の端部は、切欠部2a,2b;2b,2c;2c,2d;2d,2aに位置させている。
これらの熱媒循環用パイプ3の4経路のうち、経路3dは蛇行させた構成とすると共にその他の経路3a,3b,3cは直線状経路として構成している。
図3に示すように、溝4は、経路の曲がり部において熱媒循環用パイプ3の外径よりも幅広(幅広部Wa)に構成しており、また経路の端部近傍において切欠部2方向に末広がり(末広がり部Wb)に構成している。一方、溝4は、以上の個所を除いては、熱媒循環用パイプ3が確実に装着できるように、熱媒循環用パイプ3の外径と同じか、または僅かに大きい幅に構成している。
以上の構成において所定の長さに予め切断した熱媒循環用パイプ3を溝4に押し込んで装着することにより、熱媒循環用パイプ3の所定の経路を構成することができ、各熱媒循環用パイプ3の経路の形状は、溝4により適宜に構成することができる。
このように熱媒循環用パイプ3の経路を構成する際、熱媒循環用パイプ3は、後述する接続用部材や供給用部材に接続可能とするように切欠部2の面から外側に適宜長突出させるような長さとする。
【0014】
ここで、板状体1は、床の荷重を支えることができる材質であれば、木質合板、パーチクルボード、発泡プラスチックス板またはこれらの複合体等の適宜の材質のものを適用することができる。
また板状体1の切欠部2は、上述したように板状体1の隅を斜めに切り欠いた直角二等辺三角形状に構成する他、従来と同様な形状、即ち、板状体1の隅を直角に切り欠いた正方形状に構成することもできる。
熱媒は、例えば温水であり、この場合、熱媒循環用パイプ3は、例えば架橋ポリエチレン等の、耐圧、耐熱、耐久性に優れた材質のパイプを使用することができる。
一方、この実施の形態では、板状体1の下側の図中◎印で示す位置、即ち、4隅の切欠部2(2a,2b,2c,2d)の近傍位置と、各隅間の中間位置と、中心位置の夫々に支持脚5を配置する構成としている。この他、支持脚5を配置する位置は、少なくとも4隅の切欠部2(2a,2b,2c,2d)の近傍位置に設ける他は、上述した位置以外の適所に設定することができ、また場合によっては、支持脚を設けない床暖房用パネルユニットとすることもできる。
【0015】
以上の構成において、複数のパネルユニットUを縦横に隣接させて配置すると、図5、図6に示すように向かい合った夫々の切欠部2により、パネルユニットUの形状に対して45゜回転した形状の正方形状の空間部Sが形成される。従って、この空間部Sにおいて、各経路3a,3b,3c,3dの熱媒循環用パイプ3の所定の端部相互間を接続用部材10により接続して各経路を連通させ、所定の対を成す各経路の熱媒循環用パイプ3の端部を、熱源装置に連なる熱媒往き管13(後述)と熱媒還り管14(後述)に接続した供給用部材11に接続して熱媒を循環供給可能に構成することができると共に、隣接のパネルユニットU(U1,U2,U3,U4)間を接合して所定の広さの床暖房用パネルを構成することができる。
接続用部材10や供給用部材11は後述する実施の形態に示すように管継手構造のもので、これらを円滑に熱媒循環用パイプ3の端部に接続するためには、熱媒循環用パイプ3の端部を空間部Sの所定位置にもたらす必要がある。
上述したとおり、従来は、このような熱媒循環用パイプ3の位置の調整が困難であったのであるが、本発明の構成においては、上述したとおり、熱媒循環用パイプ3の経路の曲がり部Tに対応する溝4の部分に構成した幅広部Waが遊びとなるため、熱媒循環用パイプ3の端部位置を、その長さ方向に調整することができる。このような長さ方向の調整量が余り必要でない場合には、幅広部Waを構成する経路の曲がり部は、経路の端部から1回目の曲がり部のみとすることができる。しかし、図に示すように全ての曲がり部に幅広部Waを構成した実施の形態の場合には、夫々の幅広部Waにより順次位置を調整することにより、大きな調整量を得ることができる。
また本発明では、熱媒循環用パイプ3の経路の端部近傍に対応する溝の部分に切欠部方向に構成した末広がり部Wbが遊びとなるため、熱媒循環用パイプの端部位置を横方向に調整することができる。
こうして本発明では、管継手構造の接続用部材10や供給用部材11を熱媒循環用パイプ3に接続する際に、熱媒循環用パイプ3の端部の位置を、これらの部材10,11に応じて適切に調整することができる。
幅広部Waと末広がり部Wbは、図示の実施の形態のように両方を適用してもよいが、いずれか一方のみを適用することもできる。
【0016】
次に、この実施の形態において、隣接のパネルユニットU間の接合は、上記低段部7により空間部Sの周縁に形成される正方形状の低段部に、図6、図8、図9に示すように接合板6を嵌合し、釘等で板状体1に固定することにより行う。 このような接合方法を適用するために、溝4には図7〜図9に示すように低段部7に対応して傾斜部8を形成しており、このため溝4に装着する熱媒循環用パイプ3の端部側は図7に示すように傾斜部8を経て接合板6の下側から空間部Sに至る構成としている。
【0017】
上述したように図5は複数のパネルユニットUを縦横に隣接させて構成する床暖房用パネルの第1の形態を示すもので、この形態は、縦横に隣接させた複数のパネルユニットUの隣接する4つを1群とする構成である。
即ち、図5に示すものでは、縦横に隣接させたパネルユニットの隣接する4つU1,U2,U3,U4を1群とし、その中心側に位置する切欠部2により構成される空間部Sにおいて、各切欠部に位置する夫々のパネルユニットUの2経路の熱媒循環用パイプ3の端部を上記供給用部材11、この場合ヘッダーに接続すると共に、上記1群の周囲側に位置する切欠部2により構成される空間部S′において、各切欠部に位置する2経路の熱媒循環用パイプ3の端部相互間を接続用部材10により接続することにより、上記1群を構成する隣接の4つのパネルユニットの熱媒循環用パイプ3に1群の中心側から並列に熱媒を循環供給可能に構成している。このような熱媒の循環形態自体は図18に示す従来のものと同様である。この他、熱媒の循環形態としては、上記隣接の4つのパネルユニットUの熱媒循環用パイプ3を全て直列に接続して循環する構成としたり、直並列に接続して循環する構成とする等、適宜である。また循環の系統が共通の1群のパネルユニットUの数も、4つ以上とすることができる。
【0018】
以上のように構成する床暖房用パネルは、例えば図9に示すように夫々のパネルユニットUに配置した支持脚5により床スラブ9等から所定の高さに支持することができる。この際、支持脚5は、以上の施工に先んじて予め板状体1の所定位置に固定しておく一体構成としても良いし、施工時に所定位置に固定するような構成とすることができる。
そして以上のように構成した床暖房用パネルの上側に、例えばフローリング床等の仕上床材12を積層して床を構成することができる。即ち、本発明では、接合板6を空間部Sの周囲の低段部7に嵌合して各パネルユニットUに固定すれば、接合板6は、空間部Sを塞ぐと同時に隣接した4つのパネルユニットUを接合することができ、更に、各パネルユニットUの上面と接合板6の上面は同一平面上となるので、従来のように捨貼合板を積層せずに上記フローリング床等の仕上床材12を積層することができる。勿論、場合によっては捨貼合板を積層することもできる。
【0019】
ここで、1群の4つのパネルユニットUの熱媒循環用パイプ3を全て直列に接続する循環形態の例につき、接続用部材10と供給用部材11の具体例を説明する。まず図10は空間部Sの近傍を拡大し、一部を便宜的に断面表示した平面図、図11は接合板6で接合した状態における図10のD−D線断面図である。そして図12〜図14は接続用部材10と供給用部材11を構成する要素の正面図である。
この具体例では、接続用部材10は、図13に示すメス部材15と図12に示すオス部材16とから構成している。メス部材15は両端を閉じたプラスチックス製等の筒体17の両端側の横方向に接続筒部18を突出させ、夫々の接続筒部18の先端にフランジ部19を設けた構成である。またオス部材16は90゜曲がったパイプ20の一方の端側に熱媒循環用パイプ3への嵌入筒部21を設けると共に、他方の端側にはメス部材15の接続筒部18への嵌入筒部22を設けた構成であり、嵌入筒部21,22の夫々には水密的な接続を保持する手段を設けている。即ち、この例では、架橋ポリエチレン等の弾性変形が可能な材質の熱媒循環用パイプ3内に嵌入する嵌入筒部21は、いわゆる竹の子と称される凹凸部を設けた構成としており、また弾性変形のしにくい材質のメス部材15の接続筒部18内に嵌入する嵌入筒部22は、外周にゴムパッキン23を装着した構成としている。また嵌入筒部22の後側には、接続筒部18のフランジ部19と当接するフランジ部24を設けている。
【0020】
次に供給用部材11は、図12に示すメス部材25と図10に示すオス部材16とから構成している。即ち、オス部材16は接続用部材10と供給用部材11に兼用する部材である。従って、メス部材25は、概ね、接続用部材10用のメス部材15と同様な構成であり、筒体17の両端側の横方向に、オス部材16の嵌入筒部22を嵌入させる接続筒部18を突出させ、夫々の接続筒部18の先端にフランジ部19を設けている。そして、このような構成に加えて、メス部材25は、筒体17の一端側は閉止せずに熱媒往き管13及び熱媒還り管14への嵌入筒部26を設けた構成としており、この嵌入筒部26には、水密的な接続を保持する手段としての竹の子と称される凹凸部を設けている。
【0021】
以上の構成においては、接続する2つの経路の熱媒循環用パイプ3の夫々の端部にオス部材16の嵌入筒部21を嵌入すると共に、夫々の嵌入筒部22をメス部材15の接続筒部18に嵌入することにより、空間部S、S′の下方において2つの経路を連通することができる。
【0022】
また熱媒往き管13又は熱媒還り管14に接続する経路の熱媒循環用パイプ3には、上記と同様にオス部材16の嵌入筒部21を嵌入すると共に、夫々の嵌入筒部22をメス部材25の接続筒部18に嵌入し、さらにメス部材25の嵌入筒部26を熱媒往き管13又は熱媒還り管14に接続することにより、隣接する2つの経路の熱媒循環用パイプ3と、熱媒往き管13又は熱媒還り管14を、空間部Sの下方において供給用部材11を介して接続することができる。
尚、図示は省略しているが、オス部材16とメス部材15,25の接続においては、当接したフランジ24,19をクリップ等で挟持することにより、水圧による外れを防止することができる。
【0023】
次に図15はパネルユニットUを複数縦横に隣接させて構成する本発明の床暖房用パネルの第2の実施の形態を示すもので、この形態では、各パネルユニットUは2隅にのみ切欠部2を設けている構成である。そして熱媒循環用パイプ3の経路は、切欠部2a,2b間に2経路3s,3wを設けている。これらの経路3s,3wに関する溝4の構成は上述した実施の形態と同様である。
この構成においてこれらのパネルユニットUを縦横に隣接させ、隣接させた3つのパネルユニットU1,U2,U3を1群として、群を列設し、夫々の列a,b,c,d,…毎に直列に熱媒を循環供給する構成としている。そしてこれらの複数のパネルユニットUは図16に示すように、上述した従来のものと同様に、捨貼合板27により空間部Sを塞ぐと共に隣接するパネルユニットU間を接合し、次いで仕上床板12を固定して仕様状態としている。
尚、この形態において、上述の形態と同様な要素には同一の符号を付して重複する説明は省略する。
【0024】
この形態においては、切欠部2a,2dを設けていないパネルユニットUの辺の夫々が一線上となる隣接部分では空間部が形成されないので、この空間部から床下空間等に熱が放散することを防ぐことができる。
【0025】
次に図17は本発明にかかる床暖房用パネルの第3の実施の形態を示すものである。この実施の形態では、方形の板状体1の辺の中央部に切欠部2(2a,2b,2c,2d)を設け、切欠部の端縁から内側に低段部7を構成すると共に、熱媒循環用パイプ3の端部を、少なくとも一つの切欠部2aに配置してパネルユニットUを構成している。
このパネルユニットUの複数を縦横に隣接させて所望の広さに構成すると、向かい合った切欠部2により空間部S、S′が構成され、これらの空間部S、S′の周囲に形成される低段部7に、その深さと同じ厚さの接合板8を嵌合し、接合板8を各パネルユニットUに固定することにより隣接するパネルユニットUを接合する構成である。
尚、この実施の形態において、熱媒循環用パイプ3の経路は、以上の実施の形態と同様な構成の溝4により構成し、その数や形状、切欠部2の形状等は適宜である。
【0026】
【発明の効果】
本発明は以上のとおり、切欠部を設けた板状体に熱媒循環用パイプの経路を設けて成るパネルユニットの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成すると共に、隣接する切欠部により空間部を構成するものにおいて、熱媒循環用パイプの経路の曲がり部に対応する溝の部分に幅広部を構成したり、熱媒循環用パイプの経路の端部近傍に対応する溝の部分に切欠部方向に末広がり部を構成したので、熱媒循環用パイプの端部位置を適宜に調整することができ、管継手構造の供給用部材や接続用部材の接続が非常に容易になるという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor heating panel unit and a floor heating panel using the same.
[0002]
[Prior art]
2. Description of the Related Art Recently, it has been proposed that a plurality of panel units provided with heat medium circulation pipes are vertically and horizontally adjacent to each other to form a floor heating panel having a desired size.
For example, in the specification and drawings attached to the earlier application of the applicant of the present application, Japanese Patent Application No. 8-242855, each panel unit has a square plate shape as shown in FIGS. Notches b are provided at the four corners of a, support legs c (positions are indicated by ◎) are provided below the notches b, and the heat medium circulation pipe d is meandered to form one path. In this configuration, both ends of the heat medium circulation pipe d are located at the notch b at one corner. In this panel unit e, the shape of the cutout portion b is a square shape with a corner cutout at a right angle.
[0003]
In this configuration, when each panel unit e is adjacent to each other as a group so that four corners of the heat medium circulation pipe d are positioned so that the two corners thereof are opposed to each other, the notches b of the panel units e make the four notches. A double-sized square space f is formed. In this space f, the end of each heat medium circulation pipe d is connected to the heat source device, the heat medium feed pipe, the header h of the heat medium return pipe, and the like. To supply hot water in a circulating manner, or to connect adjacent panel units e with a connecting member g such as a strip-shaped metal fitting.
Thereafter, in order to cover the space portion f, a laminating plate i is laminated at least on the upper side of the panel unit e, and a finishing floor material j such as a flooring floor is laminated on the upper side thereof to form a floor.
[0004]
In the above configuration, the path of the heat medium circulating pipe d is configured by mounting the heat medium circulating pipe d in a groove (not shown) formed in the plate-shaped body a, and then the heat medium located in the notch b. The supply member is connected to an end of the medium circulation pipe d. The groove has no play in order to securely mount the heat medium circulation pipe d.
Further, in another invention by the present inventors, a path of a plurality of heat medium circulating pipes is formed in each panel unit, and an end of each heat medium circulating pipe is positioned in each notch, and the space In the part, between the end portions of the heat medium circulating pipes of the same panel unit or between the end portions of the heat medium circulating pipes of adjacent panel units are connected by a connecting member of a pipe joint structure to form an appropriate series path. Like that.
[0005]
[Problems to be solved by the invention]
When the heat medium circulation pipe is mounted in the groove to form a path, it is not always possible to mount the pipes in the same state, so the position of the end of the heat medium circulation pipe is shifted from a predetermined position. Sometimes. However, since the groove is configured such that the heat medium circulation pipe is mounted without play, the position of the end of the heat medium circulation pipe cannot be adjusted. For this reason, it may be difficult to connect the supply member and the connection member of the pipe joint structure.
An object of the present invention is to solve such a problem.
