Description

【０００１】
【発明の属する技術分野】
本発明は、ユニット建物であって、特に空調用ダクトの構造に関する。
【０００２】
【従来の技術】
近年、ひとつの空調機をダクトを通して複数の居室と接続し、ひとつの空調機で複数の居室を同時に冷暖房できるような空調システムが提案されている。そして、このような空調システムを、複数の建物ユニットを隣接配置させてなる建物ユニットに採用した例も特開平４−４８１３３号公報や特開平９−４９６４４号公報によって公知である。
【０００３】
ところで、空調用ダクトは、美観上、居室以外のスペースに設けることが望まれている。すなわち、特開平４−４８１３３号公報の建物ユニットでは、柱や梁等の構造体を中空筒状の部材で形成し、この中空筒状の部材を空調用ダクトとして利用している。また、特開平９−４９６４４号公報の建物ユニットでは、隣接する建物ユニットの間の隙間に円形管からなる空調用ダクトを配管している。
【０００４】
【発明が解決しようとする課題】
しかしながら、前者のユニット建物にあっては、空調機の音や風の音が構造体に直接伝わるので、これらの雑音が居室内に伝わり易いという問題がある。
【０００５】
また、後者のユニット建物にあっては、隣接する建物ユニットの間隔よりも小さい口径の空調用ダクトを用いていたために、風路の断面積が非常に小さいことにより、風量不足になる虞がある。
【０００６】
そこで、本発明は、上記のような問題に着目し、ユニット建物のデッドスペースに空調用ダクトを設けながら、遮音性を確保すると共に、空調に必要な風量を十分に確保することができるようにすることを目的としている。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明では、互いに間隔をおいて隣接して配置され且つそれぞれの間で対向する壁を有する複数の建物ユニットで構成され、互いに隣接する前記各建物ユニットの前記壁間の隙間に空調用ダクトが設けられているユニット建物において、前記空調用ダクトは前記各建物ユニットの前記各壁とは別に形成された部材からなり、前記空調用ダクトの断面形状が矩形で、前記空調用ダクトの断面の短辺長さが隣接する前記建物ユニット間の間隔に略等しい構成とし、請求項２記載の発明では、請求項１記載の発明において、前記空調用ダクトの断面の長辺長さが、この空調用ダクトに面している建物ユニットの前記壁の横幅あるいは縦幅に略等しい構成とし、請求項３記載の発明では、請求項１または２記載の発明において、前記空調用ダクトが、扁平管材で形成されている構成とし、請求項４記載の発明では、請求項３記載の空調用ダクトが、階下の建物ユニットの前記壁間の隙間と、階上の建物ユニットの前記壁間の隙間のそれぞれに設けられており、階下の空調用ダクトの上端部と階上の空調用ダクトの下端部が、筒状のジョイント部材を介して接続されている構成とした。
【０００８】
請求項５記載の発明では、請求項１または２記載の発明において、前記空調用ダクトが、隣接する建物ユニットの対向面のそれぞれに取着された一対の面材と、この一対の面材間に略平行に挟着された一対の気密部材と、で形成されている構成とし、請求項６記載の発明では、前記請求項５記載の発明において、前記気密部材に芯材が長手方向略全長にわたって設けられている構成とし、請求項７記載の発明では、前記請求項５または６記載の発明において、前記気密部材の面材側対向面に滑動フィルムが貼設されている構成とした。
【０００９】
さらに、請求項８記載の発明では、請求項５ないし７記載の空調用ダクトが、階下の建物ユニットの前記壁間の隙間と、階上の建物ユニットの前記壁間の隙間のそれぞれに設けられており、階下の空調用ダクトの上端部と階上の空調用ダクトの下端部が、粘着材で接着されている構成とし、請求項９記載の発明では、請求項１ないし８記載の発明において、一階の床下に空調機が設けられていると共に、この空調機に接続された床下ダクトが設けられており、この床下ダクトは、ユニット建物の基礎に設けられている基礎内ダクトを介して前記空調用ダクトと連通している構成とし、請求項１０記載の発明では、請求項１ないし８記載の発明において、一階の床下に空調機が設けられていると共に、この空調機に接続された床下ダクトが設けられており、この床下ダクトは、前記ユニット建物の基礎に設けられている切欠部に端部が格納され、その端部が上方に折曲されて前記空調用ダクトの下端部に接続されている構成とした。
【００１０】
また、請求項１１記載の発明では、請求項１ないし１０記載の発明において、階上の建物ユニットの床と階下の建物ユニットの天井との間の隙間に天井裏ダクトが横引き配管され、この天井裏ダクトが前記空調用ダクトと接続されている構成とした。
【００１１】
また、請求項１２記載の発明では、請求項４記載のユニット建物における空調用ダクトの接続方法において、階下の空調用ダクトの上端部に筒状のジョイント部材の下半分を嵌合し、下端部の一側面を切り欠いた階上の空調用ダクトの下端部を前記ジョイント部材の上半分と嵌合させ、前記階上の空調用ダクトの切欠部を板材で塞ぐようにし、請求項１３記載の発明では、前記請求項１２記載の発明において、前記切欠部を、前記空調用ダクトの長辺側に設けるようにした。
【００１２】
【作用】
請求項１ないし１１記載の発明では、空調用ダクトの断面形状が矩形で、断面の短辺長さが隣接する建物ユニット間の間隔に略等しいので、建物ユニット間の隙間よりも小さい口径の空調用ダクト、つまり、従来使用していたダクトよりも風路の断面積を大きくすることができ、風量を多く確保することができる。
また、建物ユニットの構造体から離れた位置に空調用ダクトを設けることができるので、空調機や風等の雑音が居室内に伝わり難くすることもできる。
【００１３】
特に、請求項２記載の発明では、空調用ダクトの断面の長辺長さが、この空調用ダクトに面している建物ユニットの壁の横幅あるいは縦幅に略等しいので、建物ユニット間の隙間のほとんどを風路として利用することができる。
【００１４】
請求項３記載の発明では、空調用ダクトが、扁平管材で形成されているので、予め工場内で空調用ダクトを建物ユニットに取り付けておくことができ、施工現場での作業手間を省くこともできる。
【００１５】
請求項４記載の発明では、空調用ダクトが、階下の建物ユニットの壁間の隙間と、階上の建物ユニットの壁間の隙間のそれぞれに設けられており、階下の空調用ダクトの上端部と階上の空調用ダクトの下端部がジョイント部材を介して接続されているので、階上と階下との間からの風洩れを確実に防止することができる。
【００１６】
請求項５記載の発明では、空調用ダクトが、隣接する建物ユニットの対向面のそれぞれに取着された一対の面材と、この一対の面材間に略平行に挟着された一対の気密部材と、で形成されているので、予め工場内で面材を建物ユニットに取り付けておくことができ、施工現場での配管作業の手間を省くこともできる。
【００１７】
請求項６記載の発明では、気密部材に芯材が長手方向略全長にわたって設けられているので、気密部材を前記一対の面材間に押し込む時に、気密部材が折れたり曲ったりするのを防止することができる。
【００１８】
請求項７記載の発明では、気密部材の面材側対向面に滑動フィルムが貼設されているので、気密部材を前記一対の面材間に押し込む時に生じる気密部材と面材との間の摩擦抵抗を小さくすることができる。
【００１９】
請求項８記載の発明では、空調用ダクトが、階下の建物ユニットの壁間の隙間と階上の建物ユニットの壁間の隙間のそれぞれに設けられており、階下の空調用ダクトの上端部と階上の空調用ダクトの下端部を接着させているので、階上と階下との間からの風洩れを確実に防止することができる。
【００２０】
請求項９記載の発明では、一階の床下に空調機が設けられていると共に、この空調機に接続された床下ダクトが設けられており、この床下ダクトは、ユニット建物の基礎に設けられている基礎内ダクトを介して前記空調用ダクトと連通しているので、建物ユニット間の空調用ダクトと一階の床下に設けられている空調機との間の配管作業を省略することができる。
【００２１】
請求項１０記載の発明では、一階の床下に空調機が設けられていると共に、この空調機に接続された床下ダクトが設けられており、この床下ダクトは、前記ユニット建物の基礎に設けられている切欠部に端部が格納され、その端部が上方に折曲されて前記空調用ダクトの下端部に接続されているので、建物ユニット間の空調用ダクトと一階の床下に設けられている空調機との間の配管作業を省略することができる。
【００２２】
請求項１１記載の発明では、階上の建物ユニットの床と階下の建物ユニットの天井との間の隙間に天井裏ダクトが横引き配管され、この天井裏ダクトが前記空調用ダクトと接続されているので、前記空調用ダクトから離れた位置に配置されている部屋へも、これらの空調用ダクトと天井裏ダクトを通して空気を搬送することができる。
【００２３】
請求項１２記載の発明では、請求項４記載の建物ユニットにおける空調用ダクトの接続方法において、階上の空調用ダクトの下端部を前記ジョイント部材の上半分と嵌合させる時に、空調用ダクトの切欠部から空調用ダクト内にジョイント部材を挿入させることができるので、空調用ダクトとジョイント部材との位置合わせを厳密に行わなくてもこれらを嵌合させることができる。
【００２４】
請求項１３記載の発明では、前記切欠部を、前記空調用ダクトの長辺側に設けるようにしたので、階上の空調用ダクトの下端部を前記ジョイント部材の上半分と嵌合させる時の作業をより容易に行うことができる。
【００２５】
【発明の実施の形態】
以下、図１〜図１９に基づいて、実施の形態のユニット建物について詳述する。
【００２６】
まず、図１〜図４を参照しながら、このユニット建物の空調システムの概略について説明する。
図１は実施の形態のユニット建物の空調システム全体を示す斜視図、図２は実施の形態のユニット建物の空調システムの一階床下部分の構成を示す拡大斜視図、図３は実施の形態のユニット建物の空調システムの一階床下部分の構成を示す平面図、図４は実施の形態のユニット建物の空調システムの一階床下部分の要部の構成を示す平面図で、図中Ａは基礎、Ｂは一階建物ユニット、Ｃは二階建物ユニットである。なお、図示は省略しているが、前記二階建物ユニットＣの上には三階建物ユニットが積載される。
【００２７】
この空調システムでは、一階建物ユニットＢの床下に、空調機１、ダクト用ロスナイ２、床下ダクト３等が吊り下げられ、基礎Ａに、前記床下ダクト３と連通する基礎内ダクト４ａ，４ｂが設けられている。また、隣接する一階建物ユニットＡの妻壁間の隙間には、前記基礎内ダクト４ａ，４ｂと連通するユニット間ダクト５ａ，５ｂが縦引き配管され、隣接する二階建物ユニットＣの妻壁間の隙間には、一階のユニット間ダクト５ａ，５ｂと連通する二階のユニット間ダクト５ｃ，５ｄが縦引き配管されている。更に、一階建物ユニットＢの天井と二階建物ユニットＣの床間の隙間、ならびに、二階建物ユニットＣの天井と三階建物ユニットの床間の隙間のそれぞれにも天井裏ダクト６ａ，６ｂが横引き配管され、前記天井裏ダクト６ａは、隣接する２つの一階建物ユニットＢ，Ｂに跨がって設けられている。
【００２８】
なお、一階建物ユニットＢの壁には、一階のユニット間ダクト５ａ，５ｂの吹出口５１ａ，５１ｂが設けられ、一階建物ユニットＢの天井には、一階の天井裏ダクト６ａの吹出口６１ａが設けられている。また、二階建物ユニットＣの壁には、二階のユニット間ダクト５ｃ，５ｄの吹出口５１ｃ，５１ｄが設けられ、三階建物ユニットの床には、二階の天井裏ダクト６ｂの吹出口６１ｂが設けられている。
【００２９】
すなわち、空調システムを作動させると、空調機１で加熱あるいは冷却された空気が、床下ダクト３を通して一階のユニット間ダクト５ａ，５ｂに送り込まれる。一階のユニット間ダクト５ａ，５ｂに送り込まれた空気は、一階建物ユニットＢの妻壁の吹出口５１ａ，５１ｂから一階の居室に吹き出すと共に、一，二階間の天井裏ダクト６ａを通して天井の吹出口６１ａから一階の別の居室にも吹き出す。また、二階のユニット間ダクト５ｃ，５ｄを通して、二階建物ユニットＣの妻壁の吹出口５１ｃ，５１ｄから二階の居室に吹き出すと共に、二階の天井裏ダクト６ｂを通して吹出口６１ｂから三階の居室にも吹き出す。
【００３０】
次に、図５〜図１９を参照しながら、空調システムの詳細を説明する。
図５は図４のＶ−Ｖ断面図、図６は図４のVI−VI断面図、図７は図４のＶII−ＶII断面図、図８は図４のVIII−VIII断面図、図９は図５のXI−XI断面図、図１０は図７のＸ−Ｘ断面図、図１１は二階のユニット間ダクトの上端部構造を示す縦断面図、図１２は二階のユニット間ダクトと天井裏ダクトの接続構造を示す縦断面図、図１３ならびに図１４は基礎内ダクトと一階のユニット間ダクトの接続構造を示す斜視図、図１５ならびに図１６は一階のユニット間ダクトと二階のユニット間ダクトの接続構造を示す斜視図で、図１７は一，二階間の天井裏ダクト同士の接続構造を示す縦断面図、図１８は一，二階間の天井裏ダクトの先端部の構造を示す縦断面図、図１９はユニット間ダクトと一，二階間の天井裏ダクトの接続構造を示す縦断面図、図中７ｂは一階建物ユニットＢの床、８ｂは一階建物ユニットＢの妻壁、９ｂは一階建物ユニットＢの天井、７ｃは二階建物ユニットＢの床、８ｃは二階建物ユニットＢの妻壁、９ｃは二階建物ユニットＢの天井、７ｄは三階建物ユニットの床である。
【００３１】
図５ならびに図６に示すように、空調機１やダクト用ロスナイ２等が配置されている部分の下側は地面が掘り下げられていて、空調機１ならびにダクト用ロスナイ２と地面の間には所定の間隔が設けられている。
【００３２】
基礎内ダクト４ａ，４ｂは、図７ならびに図８に示すように、基礎Ａの上面に所定の深さの溝を形成し、その溝の内面をウレタン材で被覆することによって形成されている。また、前記基礎内ダクト４ａ，４ｂは、図７に示すように、基礎Ａの側面に床下ダクト３との接続部４１が設けられている。
【００３３】
一階のユニット間ダクト５ａ，５ｂは、隣接する一階建物ユニットＢの妻壁８ｂ，８ｂ間に設けられており、図５、図７、図８に示すように、前記基礎内ダクト４ａ，４ｂと連通している。
【００３４】
図面右側の一階のユニット間ダクト５ａは、図９に示すように、断面形状が矩形の管材（例えば、グラスウールの外側をアルミ箔で被覆して管状にしたもの）で形成されていて、上下方向に風を通すように設けられている。また、このユニット間ダクト５ａは、断面の短辺長さが、隣接する一階建物ユニットＢ，Ｂ間の間隔に略等しく、断面の長辺長さが、このユニット間ダクト５ａに面している妻壁８ｂの横幅に略等しく、長さが、一階建物ユニットＢの高さに略等しくなるように形成されている。つまり、一階建物ユニットＢ，Ｂの間隔よりも小さい口径のダクト、つまり、従来使用していたダクトよりも、風路の断面積を何倍も大きくすることができ、風量を非常に多く確保することができる。
【００３５】
また、この一階のユニット間ダクト５ａと前記基礎内ダクト４ａとの接続は、図１３に示すように、ユニット間ダクト５ａならびに基礎内ダクト４ａの断面形状に対応した筒状のジョイント部材１０ａを介して行われている。すなわち、基礎Ａの上に一階建物ユニットＢを積載する前に、予め、基礎内ダクト４ａの上端部にジョイント部材１０ａを半分差し込んで接着しておき、ジョイント部材１０ａの残りの半分の外周に接着剤を塗布しておく。一方、ユニット間ダクト５ａは一階建物ユニットＢの妻壁８ｂに固定しておく。そして、一階建物ユニットＢを基礎Ａの上に積載し、一階建物ユニットＢの妻壁８ｂに固定しておいたユニット間ダクト５ａの下端部をジョイント部材１０ａに嵌合させて接着している。これにより、一階と二階の間からの風洩れを確実に防止することができる。
【００３６】
図面左側の一階のユニット間ダクト５ｂは、図１０に示すように、一階建物ユニットＢの妻壁８ｂの対向面のそれぞれに取着されている一対の面材（例えば、石膏ボード）５２，５２と、この一対の面材５２，５２間の左右両端部に略平行に挟着された一対の気密部材５３，５３と、で形成されていて、上下方向に風を通すようになっている。ちなみに、前記気密部材５３としては、例えば、発泡ポリエチレンを塩化ビニルシートで被覆したものを使用できる。また、このユニット間ダクト５ｂも、断面の短辺長さが、隣接する一階建物ユニットＢ，Ｂ間の間隔に略等しく、断面の長辺長さが、このユニット間ダクト５ｂに面している妻壁８ｂの横幅に略等しく、長さが、一階建物ユニットＢの高さに略等しくなるように形成されている。つまり、一階建物ユニットＢ，Ｂの間隔よりも小さい口径のダクト、つまり、従来使用していたダクトよりも、風路の断面積を何倍も大きくすることができ、風量を非常に多く確保することができる。
【００３７】
なお、この一階のユニット間ダクト５ｂと前記基礎内ダクト４ｂとの接続は、図１４に示すように、これらを直接接着させることによって行われている。すなわち、基礎Ａの上に一階建物ユニットＢを積載する前に、予め、基礎内ダクト４ｂの上端部とユニット間ダクト５ｂの下端部の片方あるいは両方に接着剤を塗布しておき、基礎Ａの上に一階建物ユニットＢを積載すると同時にこれらを接着している。これにより、一階と二階の間からの風洩れを確実に防止することができる。
【００３８】
二階のユニット間ダクト５ｃ，５ｄは、隣接する二階建物ユニットＣ，Ｃの妻壁８ｃ，８ｃ間に設けられており、前記一階のユニット間ダクト５ａ，５ｂとそれぞれ連通している。前記二階のユニット間ダクト５ｃ，５ｄの構成は、ぞれぞれ一階のユニット間ダクト５ａ，５ｂの構成と同一なので説明を省略する。
【００３９】
図面右側の一階のユニット間ダクト５ａと前記二階のユニット間ダクト５ｃとの接続は、図１５に示すように、これらユニット間ダクト５ａ，５ｃの断面形状に対応した筒状のジョイント部材１０ｂを介して行われている。すなわち、一階建物ユニットＢの上に二階建物ユニットＣを積載する前に、予め、一階のユニット間ダクト５ａの上端部にジョイント部材１０ｂの半分を嵌合させて接着しておき、ジョイント部材１０ｂの残りの半分の外周に接着剤を塗布しておく。一方、二階のユニット間ダクト５ｃは二階建物ユニットＣの妻壁８ｃに固定しておく。そして、二階建物ユニットＣを一階建物ユニットＢの上に積載し、二階建物ユニットＣの妻壁８ｃに固定しておいたユニット間ダクト５ｃの下端部をジョイント部材１０ｂに嵌合させて接着している。
【００４０】
また、図面左側の一階のユニット間ダクト５ｂと二階のユニット間ダクト５ｄとの接続は、図１６に示すように、これらを直接接着させることによって行われている。すなわち、一階建物ユニットＢの上に二階建物ユニットＣを積載する前に、予め、一階のユニット間ダクト５ｂの上端部と二階のユニット間ダクト５ｄの下端部の片方あるいは両方に接着剤を塗布しておき、一階建物ユニットＢの上に二階建物ユニットＣを積載すると同時にこれらを接着している。
【００４１】
更に、前記扁平管材からなるユニット間ダクト５ａ，５ｃは、予め工場内で一階建物ユニットＢの妻壁８ｂと二階建物ユニットＣの妻壁８ｃに取着しておくことができる。
【００４２】
一，二階間の天井裏ダクト６ａは、図１７〜図１９に示すように、一階建物ユニットＢの天井９ｂと二階建物ユニットＣの床７ｃ間の隙間に設けられており、一階のユニット間ダクト５ａならびに二階のユニット間ダクト５ｃと連通している。また、この一，二階間の天井裏ダクト６ａ，６ａ同士の接続は、図１７に示すように、天井裏ダクト６ａ，６ａの継ぎ目にジョイント部材１０ｄを内挿させ、天井裏ダクト６ａとジョイント部材１０ｄを接着させることで行われている。７ｅは各二階建物ユニットＣ，Ｃの床梁であり各天井裏ダクト６ａはこの床梁７ｅを貫通し、床梁７ｅ，７ｅ間で接続されている。更に、隣接する一階建物ユニットＢ，Ｂに跨がる部分においては、天井裏ダクト６ａ，６ａ間に継ぎダクト６ｃを設け、この継ぎダクト６ｃとその両側の天井裏ダクト６ａ，６ａの継ぎ目にジョイント部材１０ｅを内挿させ、これら天井裏ダクト６ａ，６ａとジョイント部材１０ｅを接着させることで行われている。
【００４３】
二，三階間の天井裏ダクト６ｂは、図１２に示すように、二階建物ユニットＣの天井９ｃと三階建物ユニットの床７ｄ間の隙間に設けられており、二階のユニット間ダクト５ｄと連通している。二階のユニット間ダクト５ｄと前記天井裏ダクト６ｂは、ユニット間ダクト５ｄならびに天井裏ダクト６ｂの断面形状に対応した筒状のジョイント部材１０ｃを介して行われている。
【００４４】
つまり、本実施の形態では、建物のデッドスペースである一階建物ユニットＢ間の隙間ならびに二階建物ユニットＣ間の隙間に空調用ダクトを設けた構造としながらも、風路の断面積を大きくして空調に必要な風量を十分に確保することができる。また、一階建物ユニットＢならびに二階建物ユニットＣの構造体から離れた位置にユニット内ダクト５ａ，５ｂ，５ｃ，５ｄを設けているので、空調機や風等の雑音が居室内に伝わり難く、遮音性も確保することができる。
【００４５】
また、ユニット間ダクト５ａ，５ｃは、予め工場内で一階建物ユニットＢと二階建物ユニットＣのそれぞれに取り付けておくことができるし、ユニット間ダクト５ｂ，５ｄは、これらの構成部品である面材５２を予め工場内で一階建物ユニットＢと二階建物ユニットＣのそれぞれに取り付けておくことができるので、施工現場での配管作業の手間を省くこともできる。
【００４６】
更に、床下ダクト３と一階のユニット間ダクト５ａ，５ｂとを、基礎Ａに設けた基礎内ダクト４ａ，４ｂで接続していることによっても、施工現場での配管作業を省略することができる。
【００４７】
また、一階建物ユニットＢの天井９ｂと二階建物ユニットＣの床７ｃとの間の隙間に天井裏ダクト６ａが横引き配管され、この天井裏ダクト６ａが空調用ダクト５ａ，５ｃと連通しているので、これら空調用ダクト５ａ，５ｃから離れた位置に配置されている一階の部屋へも、これらの空調用ダクト５ａ，５ｃと天井裏ダクト６ａを通して空調機１からの空気を搬送することができる。同様にして、二階建物ユニットＣの天井９ｃと三階建物ユニットの床との間の隙間に天井裏ダクト６ｂが横引き配管され、この天井裏ダクト６ｂが二階の空調用ダクト５ｄと連通しているので、この空調用ダクト５ｄから離れた位置に配置されている三階の部屋へも、これら空調用ダクト５ｄと天井裏ダクト６ａを通して空調機１からの空気を搬送することができる。
【００４８】
図２０ならびに図２１は、一階のユニット間ダクトと二階のユニット間ダクトの気密部材の変形例を示す斜視図である。
図２０の気密部材５３ａは、亜鉛鉄板５３１を芯材とし、その亜鉛鉄板５３１の両面にスチレン発泡体５３２を貼設すると共に、各スチレン発泡体５３２の両側面に棒状の軟質ウレタン発泡体５３３を貼設し、更に滑動フィルムとしてポリエチレンフィルム５３４を、前記軟質ウレタン発泡体５３３の外側面に架け渡し状態で設けることによって形成されている。なお、前記亜鉛鉄板５３１は、建物ユニット間への差し込み方向に対して平行に設けられ、前記軟質ウレタン発泡体５３３は、面材５２側対向面に配設されている。
【００４９】
また、図２１の気密部材５３ｂは、亜鉛鉄板５３１を芯材とし、その亜鉛鉄板５３１の両面にスチレン発泡体５３２を貼設すると共に、前記亜鉛鉄板５３１ならびに前記スチレン発泡体５３２を板状の軟質ウレタン発泡体５３３で挟み込み、更に、ポリエチレンフィルム５３４を面材５２側対向面と建物ユニット間への差し込み方向先端側側面とに貼設することによって形成されている。なお、前記亜鉛鉄板５３１は、建物ユニット間への差し込み方向に対して直角に設けられ、前記軟質ウレタン発泡体５３３は、面材５２側対向面に配設されている。更に、気密部材５３ｂは、建物ユニット間への差し込み方向先端側の角部が面取りされた断面六角形に形成されていて、面材５２，５２間への差し込みが容易に行うことができるようになっている。
【００５０】
つまり、前記気密部材５３ａ，５３ｂにあっては、亜鉛鉄板５３１を芯材としているので、気密部材５３ａ，５３ｂを前記一対の面材５２，５２間に押し込む時に、気密部材５３ａ，５３ｂが折れたり曲ったりするのを防止することができ、高い気密性を確保することができる。また、気密部材５３ａ，５３ｂの面材５２側対向面には、滑動フィルムとしてポリエチレンフィルム５３４が貼設されているので、気密部材５３ａ，５３ｂを前記一対の面材５２，５２間に押し込む時に生じる気密部材５３ａ，５３ｂと面材５２との間の摩擦抵抗が小さくなり、気密部材５３ａ，５３ｂを前記一対の面材５２，５２間に楽に押し込むことができる。
【００５１】
図２２ならびに図２３は、一階のユニット間ダクト５ａと二階のユニット間ダクト５ｃの接続構造の変形例を示す斜視図である。
この接続構造では、予め二階のユニット間ダクト５ｃの下端部の長辺側の一側面を切り欠いておき、そのユニット間ダクト５ｃの下端部を前記ジョイント部材１０ｂの上半分と嵌合させた後に、前記二階のユニット間ダクト５ｃの切欠部５４を板材５５で塞ぐようにしている。そうすることにより、二階のユニット間ダクト５ｃの下端部を前記ジョイント部材１０ｂの上半分と嵌合させる時に、ユニット間ダクト５ｃの切欠部５４からユニット間ダクト５ｃ内にジョイント部材１０ｂを挿入させることができるので、ユニット間ダクト５ｃとジョイント部材１０ｂとの位置合わせを厳密に行わなくてもこれらを嵌合させることができるので作業効率が向上する。
【００５２】
図２４は床下ダクトの変形例を示す斜視図である。
この床下ダクト３ａは、端部３１が上方に折曲されていて、基礎Ａに設けられている切欠部１１に格納され、かつ、その端部３１が一階のユニット間ダクト５ａの下端部に接続されている。つまり、建物の基礎Ａに基礎内ダクトを設置する作業ならびに、基礎内ダクトと床下ダクト３ａとの接続作業を省略することができ、施工現場での配管作業の手間を大幅に省略することができる。
【００５３】
以上、本発明の実施の形態を図面により詳述してきたが、具体的な構成はこの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における設計の変更等があっても本発明に含まれる。例えば、実施の形態では、建物ユニット間に、構成が異なる二種類のダクト（扁平配管からなるダクトと、一対の面材と一対の気密部材からなるダクト）を設けた例を示したが、ダクトを一種類に統一してもよい。また、ダクトの構成はこれらに限られず、建物ユニットの対向面のそれぞれに取着した一対のＬ形材で構成してもよいし、一方の建物ユニットに取着した面材と、他方の建物ユニットに固定した断面コの字形の溝形材と、で構成してもよい。
