Description

【０００１】
【発明の属する技術分野】
本発明は、住宅等の建築物の断熱及び気密構造、特に基礎の上面から部屋の内壁において乾式工法により構築される断熱気密構造に関するものである。
【０００２】
【従来の技術】
近年、住宅には、計画的な換気による住宅の快適性の向上や、冷暖房の効率を高めて省エネルギー化を図るために、断熱性及び気密性が求められるようになってきている。住宅等の建物の断熱気密構造には、従来より種々のものがあるが、これらは主に、建物の内部空間全体を囲むように断熱及び気密を行うものである。
【０００３】
図２６は、従来の断熱気密構造を示したものであるが、図に示すように、建物９１の屋内の壁、天井、及び床の内部に気密面及び断熱面を設け、各気密面及び断熱面を連続させることにより断熱気密ライン９２を構築して、建物の内部空間の断熱性及び気密性を確保するものである。この場合、床下については、通常は換気等が図られているため、断熱性や気密性については何ら考慮されていない。
【０００４】
【発明が解決しようとする課題】
しかし、省エネルギーや環境問題への配慮が高まるとともに、更なる冷暖房効率の向上等を図るために、住宅の断熱性及び気密性も高いレベルが要求されている。例えば寒冷地においては、図に示すように、基礎９３の外周にも断熱材を配設することにより、基礎９３の外側に断熱ライン９４を形成し、基礎９３のコンクリートがヒートブリッジとなることを抑制して、床下の断熱性の向上が図られている。このように、基礎９３に断熱ライン９４を確保する場合には、気密ラインも断熱ラインと同じ箇所に設けることが断熱及び気密の確実性や施工効率の観点から好ましい。
【０００５】
また、基礎から部屋の内壁にかけての構造は複雑なため、気密面及び断熱面を形成するための施工が煩雑となり、特に乾式工法では気密面に隙間が生じ易い。一方、ウレタン等を吹き付ける湿式工法では隙間が生じ難いものの、塩素系ガスの発生や、養生期間が必要等の問題がある。
【０００６】
本発明は、これらの点に鑑みてなされたものであり、住宅等の建築物の基礎上面から部屋の内壁又はサッシにおいて、簡易且つ確実に断熱気密ラインを構築することが可能な断熱気密構造を提供することを目的とする。
【００１０】
【課題を解決するための手段】
本発明に係る断熱気密構造は、建物の基礎の上面から和室のサッシにおける断熱気密構造であって、シート状の気密部材が、基礎上部の内縁部を覆い、且つ、サッシに沿って起立して、その上端部が床帯板の縁部を覆うように設けられ、前記気密部材の両側に、端部用気密部材が前記床帯板の側端を覆うように設けられ、前記気密部材の下端部と基礎の内側面とがシール部材により密封され、前記気密部材とサッシとの間に断熱部材が介設され、前記基礎上に、床帯板が設けられるとともに、その縁部が前記気密部材で覆われ、前記気密部材の上端部が、前記床帯板と膳板とによって挟着されたものである。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づき具体的に説明する。
図１は、本発明の第１の実施の形態に係る基礎上面から洋室の内壁における断熱気密構造を示すものである。本断熱気密構造１００が施工される基礎１の上部には、Ｃ型鋼を組み合わせてなる軸組２が組まれ、屋内側には根太３が横架され、その上に床パネル４が敷設されている。床パネル４の縁部には断熱性及び気密性を有する内壁枠５が立設され、該内壁枠５の表面に内壁ボード６が配設されている。一方、屋外側には外壁ボード７が配設されて、前記内壁枠５、内壁ボード６、及び外壁ボード７により建物の壁が構築されている。また、基礎１の外周面には、発泡合成樹脂からなる基礎断熱部材８が配設されて基礎１の断熱が施されている。このような基礎１の上部の構造において、本断熱気密構造１００は、気密部材１１と断熱部材１２とが一体となった断熱気密部材１０が基礎１の上部に配設されて、該気密部材１１が基礎１の内縁部及び床パネル４の縁部を覆い、その下端部１１ｂと基礎１の内側面とが防水気密テープ４０により密封されるとともに、その上端部１１ｄが床パネル４と内壁枠５により挟着され、該気密部材１１と軸組２との間に断熱部材１２が介設されたものである。これにより、基礎１の上部から軸組２、床パネル４、内壁枠５へと断熱気密ラインが形成される。
【００１２】
図２は、前記断熱気密部材１０の一例を示すものであるが、断熱気密部材１０は、気密部材１１の背面、即ち屋外側となる面に柱状の断熱部材１２が固定され、気密部材１１の一側端部に気密テープ１３が貼設されてなるものである。該断熱気密部材１０の長手方向の長さは任意であるが、成形加工の容易性や施工の便宜を考慮すれば約１０００mm程度が好適である。
【００１３】
前記気密部材１１は薄板状の合成樹脂であって、図に示すように、水平方向の基部１１ａから下端部１１ｂが下方へ略直角に曲折されて垂下され、他方、起立部１１ｃが上方へ略直角に曲折されて立ち上がり、さらに上端部１１ｄが起立部１１ｃから水平方向手前側へ略直角に曲折された形状のものである。このように形成された断熱気密部材１０が基礎１の上部に配置されることにより、基部１１ａ及び下端部１１ｄが基礎１の内縁部、即ち基礎１の上面及び内側面の一部を覆い、起立部１１ｃ及び上端部１１ｄが床パネル４の縁部を覆うものとなる。また、気密部材１１を断熱気密ラインを形成すべき構造部位、即ち基礎１の上部から床パネル４の縁部に合致するように予め曲折等されているので、現場で断熱気密部材１０を折り曲げ等する必要がなくなり、施工作業が容易となるとともに、施工ミス等による隙間が生じ難くなり、所望の気密性が確保される。なお、気密部材１１を構成する合成樹脂は、例えばポリエチレン等の気密性能及び防水性能に優れたものが好適である。
【００１４】
前記断熱部材１２は、前記気密部材１１と略同長さの柱状の発泡合成樹脂であり、図に示すように、前記気密部材１１の起立部１１ｃの背面に固定されている。断熱部材１２を構成する発泡合成樹脂は、例えば発泡ポリスチレン等の断熱性能に優れ、且つ成形加工性にも優れたものが好適である。気密部材１１と断熱部材１２との固定は周知の方法が採用でき、例えばエポキシ樹脂系等の接着剤を用いて貼着しても、断熱部材１２の発泡成形時に気密部材１１と熱圧着してもよい。
【００１５】
前記気密テープ１３は、所謂粘着テープであって、例えばポリエチレンフィルムやポリエチレン−アルミニウムのラミネートフィルム等の気密性能及び防水性能に優れたものが好適である。該気密テープ１３の裏面には接着剤が塗布されて離形紙が貼着されており、該気密テープ１３の略半分程度は離形紙が剥がされて、前記気密部材１１の一端の内面に、気密部材１１の形状に沿って貼り付けられており、残りの半分程度は離形紙が付いたまま、気密部材１１から側方に突出した状態となっている。従って、断熱気密部材１０を連結する際には、気密テープ１３の離形紙を剥がして、側方に突出した部分の気密テープ１３を連結すべき断熱気密部材１０の気密部材１１の内面に貼着すればよい。
【００１６】
このように、断熱気密部材１０は、基礎１、軸組２、及び床パネル４の形状に合せて成形された気密部材１１と、該気密部材１１と軸組２との間に介設される断熱部材１２とが予め一体として固定されているので、本断熱気密構造１００の施工が簡便となり、また、気密部材１１の一端には気密テープ１３が予め貼着されているので、断熱気密部材１０を基礎１の上部に連設していく際に、断熱気密部材１０同士を密着させて連結することが容易となり、該連結部の気密性も確保される。
【００１７】
なお、前記断熱気密部材１０は一例であり、例えば基礎１の出隅部や入隅部に配設されるものは、予め出隅部又は入隅部の形状に合致するように成形されている。図３及び図４は、出隅部に配設される断熱気密部材１０Ａ、入隅部に配設される断熱気密部材１０Ｂを夫々示すものであるが、図に示すように、断熱気密部材１０Ａにおいては、気密部材１１及び断熱部材１２が出隅部の形状に合致するように、図手前側へ略直角に曲折された形状となっている。該断熱気密部材１０Ａの長さも任意であるが、施工の便宜等を考慮すれば略直角に曲折された夫々を約２５０mm程度とすることが好適である。一方、断熱気密部材１０Ｂにおいては、気密部材１１は図向こう側へ略直角に曲折された形状となっており、該気密部材１１の両側端に合うように柱状の断熱部材１２が該気密部材１１の背面に固定されている。該断熱気密部材１０Ｂは入隅部のコーナー部分のみを覆うようになっており、略直角に曲折された夫々は約２４mm程度である。
【００１８】
このように、出隅部や入隅部等に配設すべき断熱気密部材１０Ａ、１０Ｂは曲折部分が多く複雑な形状となるので、例えば、現場において直線状の前記断熱気密部材１０を適宜切断し、略直角となるように連結して気密テープ等で曲折部分を密封する方法では、切断時の誤差や気密テープの折り曲げによって連結部分に隙間が生じ易く、気密性能が低下するという欠点がある上、施工作業も増加するという欠点がある。前述したように、出隅部や入隅部等の形状に合致するように予め成形された断熱気密部材１０Ａ、１０Ｂを用いることにより、気密性能が維持され、施工も容易となる。
【００１９】
また、前記断熱気密部材１０は、図１に示すように、基礎１の上部に配設されて、その気密部材１１の下端部１１ｂと基礎１の内側面とが防水気密テープ（シール部材）４０により密封されている。該防水気密テープ４０は、例えば、合成樹脂とアルミニウムのラミネートフィルムに接着剤が塗布されたもの等、乾式気密工法に使用される周知のものである。一方、気密部材１１の上端部１１ｄは床パネル４の縁部を覆っており、該上端部１１ｄは床パネル４と内壁枠５により挟着されている。これにより、基礎１の上面から床パネル４への断熱気密ラインが形成され、該断熱気密ラインが、内壁枠５の表面に形成される断熱気密ラインへと接続される。
【００２０】
また、基礎１の上面と軸組２の内側面との隙間には、防水スペーサ（シール部材）４１が貼着されて密封されている。該防水スペーサ４１は、軟質発泡合成樹脂や耐老化性ゴム等が好適であり、密封は接着剤等により直接貼りつけても、その上端及び下端等に前記防水気密テープ４０を貼り付けることとしてもよい。このように防水スペーサ４１で基礎１と軸組２との隙間を密封することにより、前記断熱気密ラインの気密性及び断熱性が一層高められ、また、該隙間から雨水等が滲入することが防止される。
【００２１】
なお、図１に示した基礎１の上部の建築物の構造は一例であり、本発明に係る断熱気密構造が図示の建築物構造に限定されないことは当然である。従って、例えば基礎１は布基礎、ベタ基礎等の種類を問わず、軸組２もＣ型鋼に限定されるものではない。
【００２２】
以下、本断熱気密構造１００の施工方法について説明する。
図５は、基礎１の平面形状を示す図であるが、本断熱気密構造１００は、出隅部Ａのように基礎１の隅部から一定方向へ、前記断熱気密部材１０を順次配設することが好適である。なお、出隅部Ａのような各出隅部には前記断熱気密部材１０Ａが、入隅部Ｂのような各入隅部には前記断熱気密部材１０Ｂが、その他の直線状の部位には前記断熱気密部材１０が配設される。
【００２３】
断熱気密部材１０を配設する前に、まず、図６に示すように、基礎１の上面と軸組２の内側面とに渡って防水スペーサ４１を貼り付け、基礎１と軸組２との隙間を密封する。防水スペーサ４１を貼り付ける際には、基礎１の上面等は十分に清掃して埃等を除去しておく。また、防水スペーサ４１の継目は防水気密テープ４０で密封し、出隅部Ａや入隅部Ｂ等は、防水スペーサ４１に適宜切り込みを設けて貼り付けた後、該切り込み部分も防水気密テープ４０で密封する。
【００２４】
つぎに、断熱気密部材１０、１０Ａ、１０Ｂを順次配設する。図７に示すように、最初に出隅部Ａに断熱気密部材１０Ａを配設する。略直角に曲折された断熱気密部材１０Ａを出隅部Ａにあわせ、さらに、気密部材１１の基部１１ａ及び下端部１１ｂが基礎１上部の内縁部Ｉを覆うように配置する。その後、図に示すように、下端部１１ｂの一部と基礎１の内側面に防水気密テープ４０を貼り付けて断熱気密部材１０Ａを仮止めしておく。
【００２５】
断熱気密部材１０Ａを出隅部Ａに仮止めした後、該断熱気密部材１０Ａから右方向へ、断熱気密部材１０を連結させながら配置する。詳細には、気密部材１０の気密テープ１３の離形紙を剥がし、断熱気密部材１０、１０Ａの端部同士を隙間なく密接させて、前記断熱気密部材１０Ａと同様に、気密部材１１の基部１１ａ及び下端部１１ｂが基礎１の内縁部Ｉを覆うように配置する。配置した後、気密テープ１３により断熱気密部材１０、１０Ａの連結部分を密封する。なお、断熱気密部材１０を順次連結させていく方向は、右方向又は左方向のいづれでもよいが、図に示すように、断熱気密部材１０の左側に気密テープ１３が貼設されている場合には、右方向へ連結させていくこととすれば、該気密テープ１３を既に配設された断熱気密部材１０Ａ等に手前側から貼り付けることとなり作業性がよい。
【００２６】
図８は、入隅部Ｂを示すものであるが、前記断熱気密部材１０を順次配設し、入隅部Ｂにおいては、基礎１のＮ芯に合わせて、断熱気密部材１０の不要な長さを切断し、切断された断熱気密部材１０を前述と同様に配設する。その後、断熱気密部材１０Ｂを、前記断熱気密部材１０の切断面に密接させて、基礎１の入隅部Ｂに合せて配置する。断熱気密部材１０Ｂも、前述と同様に、気密部材１１の基部１１ａ及び下端部１１ｂが基礎１の内縁部Ｉを覆うように配置し、気密テープ１３により断熱気密部材１０、１０Ｂの連結部分を密封する。
【００２７】
このように、基礎１の直線部分には断熱気密部材１０を、出隅部には断熱気密部材１０Ａを、入隅部には断熱気密部材１０Ｂを、それぞれを密接させながら基礎１に沿って連続的に配置していく。
【００２８】
断熱気密部材１０、１０Ａ、１０Ｂを夫々所定の位置に配置した後、図９に示すように、断熱気密部材１０、１０Ａ、１０Ｂの各下端部１１ｂと基礎１の内側面とを密封するように防水気密テープ４０を貼り付ける。防水気密テープ４０を途中で継ぐ場合には、防水気密テープ４０を十分に重ねて継目に隙間が生じないようにする。
【００２９】
その後、図１０に示すように、床受け下地４２を、大引方向と直交する方向の基礎１の上部に配設する。床受け下地４２は、平板状の基台４２ａ上に角柱４２ｂが固定されてなるものであり、大引（不図示）上に横架される根太３と同様に、基礎１の上部において、その後に敷設される床パネル４を支持する。該床受け下地４２は、基台４２ａを断熱気密部材１０、１０Ａ、１０Ｂの気密部材１１の基部１１ａ上に載置するとともに、角柱４２ｂが該気密部材１１の起立部１１ｃと接触するように配置し、基台４２ａの底面に床用弾性接着剤を塗布して気密部材１１と接着し、更に、適宜コンクリート釘やコンクリート用タッピングビス等を打ち込んで基礎１に固定する。
【００３０】
床受け下地４２を配設した後、根太３を横架し、床パネル４を敷設する。床パネル４の縁部は、図１１に示すように、大引方向と直交する方向の基礎１の上部では前記床受け下地４２により支持され、大引方向と平行な方向の基礎１の上部では根太３により支持される。断熱気密部材１０、１０Ａ、１０Ｂの気密部材１１の基部１１ａ上に、床受け下地４２又は根太３、及び床パネル４の荷重が加わることにより、気密部材１１と基礎１とが密接されて気密性が高められる。また、断熱気密部材１０、１０Ａ、１０Ｂの気密部材１１の上端部１１ｄは、該床パネル４の縁部を覆うようになっている。該上端部１１ｄ上には、その後、図１に示したように、内壁枠５が立設されることにより、床パネル４と内壁枠５とに挟着されて、床パネル４の縁部が気密部材１１により密封される。なお、床パネル４上にはフローリング等の床表面材４３が敷設される。
【００３１】
このようにして本断熱気密構造１００が施工され、基礎１の上部に沿って連続的に配設された断熱気密部材１０、１０Ａ、１０Ｂにより、基礎１の上面から洋室の床パネル４の縁部に渡って断熱気密ラインが形成される。また、周知のように、内壁枠５の表面には気密防湿シートが貼設され、内部及び裏面にはグラスウール等の断熱材が配設されて、断熱気密ラインが形成されており、本断熱気密構造１００により形成された基礎上部の断熱気密ラインが、内壁に形成された断熱気密ラインと連続し、建物全体の断熱気密ラインの一部をなすものとなる。
【００３２】
以下、前記第１の実施の形態の変形例に係る断熱気密構造２００について説明する。
本変形例に係る断熱気密構造２００は、洋室のサッシ部におけるものであり、図１２に示すように、本断熱気密構造２００が施工される基礎１の上部には、サッシ９が配設されている。該サッシ９は、洋室の床面と略同高さから開口する所謂掃出し窓の窓枠である。また、基礎１の屋内側には、根太３上に床パネル４が敷設されている。このようなサッシ９が配設された基礎１の上部の構造において、本断熱気密構造２００は、気密部材１１が基礎１の内縁部及び床パネル４の縁部を覆い、その下端部１１ｂと基礎１の内側面とが防水気密テープ４０により密封されるとともに、その上端部１１ｄが床パネル４と床表面材４３により挟着され、該気密部材１１と軸組２との間に断熱部材１４が介設されたものである。これにより、基礎１の上面からサッシ９、床パネル４へと断熱気密ラインが形成されている。
【００３３】
前記気密部材１１は、第１の実施の形態で示したものと同様であるが、その背面には断熱部材１２は固定されておらず、図１３に示すように、気密部材１１の一端に気密テープ１３が貼り付けられているのみである。また、気密部材１１及び気密テープ１３の素材等は前述と同様である。
【００３４】
前記断熱部材１４は、グラスウールやロックウール等の周知の易変形性断熱部材を所定の大きさに切断したものである。サッシ９の周囲には、土台や額縁等が取り付けられるため、釘やネジ等の固定部材が突出している場合がある。また、サッシ９の周囲にはアングルピース等の突出部分もある。そのため、前記断熱気密部材１０のように、軸組２との間に介設される所定形状の発泡合成樹脂の断熱部材１２が一体となったものは、断熱部材１２が前記固定部材やサッシ９の突出部分と当接して、基礎１上の所定位置に納まらない場合がある。本変形例のように、サッシ９が配設された基礎１上部においては、断熱部材１２が固定されていない気密部材１１を基礎１上に配設し、その後、該気密部材１１とサッシ９との間に易変形性の断熱部材１４を充填することにより、前記固定部材やサッシ９の突出部分の有無に拘わらず、基礎１の上面から、サッシ９、床パネル４へ断熱気密ラインを簡易且つ確実に形成することができる。
【００３５】
図１３〜図１６は、本断熱気密構造２００の施工方法を示すものであるが、前記第１の実施の形態と同様に、基礎１の上面とサッシ９の内側面に渡って防水スペーサ４１が貼り付けられ、基礎１とサッシ９との隙間が密封されている。また、サッシ９が配設されている部分以外の基礎１上には、前述したように、基礎１の形状に合せて断熱気密部材１０等が配設されている。
【００３６】
サッシ９以外の基礎１の上部に断熱気密部材１０等を配設した後、図１３に示すように、気密部材１１を、断熱気密部材１０と連結させながら配設する。詳細には、気密テープ１３の離形紙を剥がし、気密部材１１と既に配設されている断熱気密部材１０の端部同士を隙間なく密接させて、前述と同様に、気密部材１１の基部１１ａ及び下端部１１ｂが基礎１の内縁部Ｉを覆うように配置する。配置した後、気密テープ１３により気密部材１１と断熱気密部材１０の連結部分を密封する。このように、所要数の気密部材１１を順次連結させて配設し、既に配設されている断熱気密部材１０と連結させ、気密テープ１３により、その連結部分を密封する。
【００３７】
気密部材１１を基礎１の内縁部Ｉに配置した後、図１４に示すように、気密部材１１及び断熱気密部材１０等の各下端部１１ｂと基礎１の内側面とを密封するように防水気密テープ４０を貼り付ける。その後、前述と同様に、床受け下地４２を、大引方向と直交する方向の基礎１の上部に配設して、床用弾性接着剤及びコンクリート釘等により固定する。
【００３８】
床受け下地４２を配設した後、図１５に示すように、気密部材１１とサッシ９との間に断熱部材１４を充填する。サッシ９の突出部分等に対しては、断熱部材１４を変形させて圧入する。これにより、該断熱部材１４が気密部材１１とサッシ９との間に介設される。
【００３９】
その後、根太３を横架し、床パネル４を敷設する。床パネル４の縁部は、図１６に示すように、気密部材１１の上端部１１ｄにより覆われる。さらに、該上端部１１ｄ上に、図１２に示したように、床表面材４３を敷設し、これにより、気密部材１１の上端部１１ｄが床パネル４と床表面材４３に挟着されて、床パネル４の縁部が気密部材１１により密封される。このようにして、サッシ９が配設された基礎１上に本断熱気密構造２００を構築することができる。
【００４０】
つぎに、本発明の第２の実施の形態に係る断熱気密構造３００について説明する。
図１７は、本発明の第２の実施の形態に係る基礎上面から和室の内壁における断熱気密構造を示すものである。本断熱気密構造３００が施工される基礎１の上部には、Ｃ型鋼を組み合わせてなる軸組２が組まれ、屋内側には大引４４及び根太３が組まれ、その上に和室用床パネル４５及び畳４６が敷設されている。また、和室用床パネル４５の縁部には内壁枠受け下地４７が配設され、その上に断熱性及び気密性を有する内壁枠５が立設され、該内壁枠５の屋内側に内壁ボード６が配設されている。一方、屋外側には外壁ボード７が配設されて、前記内壁枠５、内壁ボード６、及び外壁ボード７により建物の壁が構築されている。また、基礎１の外周面には、発泡合成樹脂からなる基礎断熱部材８が配設されて基礎１の断熱が施されている。
【００４１】
このような基礎１の上部の構造において、本断熱気密構造３００は、気密部材１１と断熱部材１２とが一体となった断熱気密部材１０が基礎１の上部に配設されて、該気密部材１１が基礎１の内縁部を覆い、その下端部１１ｂと基礎１の内側面とが防水気密テープ４０により密封されるとともに、その上端部１１ｄが内壁枠受け下地４７と内壁枠５とにより挟着され、該気密部材１１と軸組２との間に断熱部材１２が介設されたものである。これにより、基礎１の上部から軸組２、内壁枠５へと断熱気密ラインが形成される。
【００４２】
前記断熱気密部材１０は、第１の実施の形態で示したものと同様に、基礎１の上部から内壁枠受け下地４７の形状に合致するように予め成形された気密部材１１の背面に柱状の断熱部材１２が固定され、気密部材１１の一側端部に気密テープ１３が貼設されてなるものであり、その詳細な説明は省略する。基礎１の上部に配設された断熱気密部材１０の気密部材１１の下端部１１ｂと基礎１の内側面とは防水気密テープ４０により密封されており、また、基礎１の上面と軸組２の内側面との隙間は、防水スペーサ４１により密封されている。
【００４３】
以下、本断熱気密構造３００の施工方法について説明する。
まず、基礎１の上面と軸組２の内側面とに渡って防水スペーサ４１を貼り付けた後、断熱気密部材１０、１０Ａ、１０Ｂを順次配設して、断熱気密部材１０、１０Ａ、１０Ｂの各下端部１１ｂと基礎１の内側面とを密封するように防水気密テープ４０を貼り付けるまでは、前記第１の実施の形態と同様である。
【００４４】
その後、図１８に示すように、和室用床パネル４５を配設し、内壁枠受け下地４７を基礎１の上部に配設する。内壁枠受け下地４７は、平板状の基台４７ａ上に角柱４７ｂが固定されてなるものであり、基礎１の上部において、その後に敷設される内壁枠５を支持する。該内壁枠受け下地４７は、基台４７ａを断熱気密部材１０、１０Ａ、１０Ｂの気密部材１１の基部１１ａ上に載置するとともに、角柱４７ｂが該気密部材１１の起立部１１ｃ及び上端部１１ｄと内接するように配置し、基台４７ａの底面に床用弾性接着剤を塗布して気密部材１１と接着し、更に、適宜コンクリート釘やコンクリート用タッピングビス等を打ち込んで基礎１に固定する。また、気密部材１１の上端部１１ｄ上から内壁枠受け下地４７にタッカー等を打ち込んで、該上端部１１ｄを内壁枠受け下地４７に固定する。なお、図１８に示すように、出隅部Ａ等において内壁枠受け下地４７の接続部分が干渉する場合は適宜切断する。その後、図１７に示したように、内壁枠５が立設されることにより、気密部材１１の上端部１１ｄが前記内壁枠受け下地４７と内壁枠５とに挟着される。なお、和室用床パネル４５上には、畳４６が敷設される。
【００４５】
このようにして本断熱気密構造３００が施工され、基礎１の上部に沿って連続的に配設された断熱気密部材１０等により、基礎１の上面から和室の内壁枠５に渡って断熱気密ラインが形成される。これにより、基礎１の上部の断熱気密ラインが、内壁に形成された断熱気密ラインと連続し、建物全体の断熱気密ラインの一部をなすものとなる。

以下、前記第２の実施の形態の変形例に係る断熱気密構造４００について説明する。
本変形例に係る断熱気密構造４００は、和室のサッシ部におけるものであり、図１９に示すように、本断熱気密構造４００が施工される基礎１の上部には、サッシ９が配設されており、基礎１の屋内側は、前述と同様に、大引４４及び根太３上に和室用床パネル４５及び畳４６が敷設されている。このようなサッシ９が配設された基礎１の上部の構造において、本断熱気密構造４００は、気密部材１１が基礎１の内縁部及び床帯板４８の縁部を覆い、その下端部１１ｂと基礎１の内側面とが防水気密テープ４０により密封されるとともに、その上端部１１ｄが床帯板４８と膳板４９ａにより挟着され、該気密部材１１及び膳板４９ａと軸組２との間に断熱部材１５が介設されたものである。これにより、基礎１の上面からサッシ９、和室用床パネル４５へと断熱気密ラインが形成されている。なお、図には表れていないが、床帯板４８の側端は端部用気密部材１６Ｒ、１６Ｌで夫々覆われており、その詳細については後述する。
【００４７】
前記気密部材１１は、第１の実施の形態の変形例で示したものと同様であるが、その背面には断熱部材１２は固定されておらず、図２０に示すように、気密部材１１の一端に気密テープ１３が貼り付けられているのみである。また、気密部材１１及び気密テープ１３の素材等は前述と同様である。また、前記断熱部材１５は、断熱部材１４と同様に、グラスウールやロックウール等の周知の易変形性断熱部材を所定の大きさに切断したものである。
【００４８】
図２０〜図２５は、本断熱気密構造４００の施工方法を示すものであるが、前記第１の実施の形態の変形例と同様に、基礎１の上面とサッシ９の内側面に渡って防水スペーサ４１が貼り付けられ、基礎１とサッシ９との隙間が密封されている。また、サッシ９が配設されている部分以外の基礎１上には、前述したように、基礎１の形状に合せて断熱気密部材１０等が配設されている。
【００４９】
サッシ９以外の基礎１の上部に断熱気密部材１０等を配設した後、図２０に示すように、気密部材１１を、断熱気密部材１０と連結させながら配設する。詳細には、まず、断熱気密部材１０との連結部分を密封する気密テープ１３の上側部分、即ち気密部材１１の起立部１１ｃ及び上端部１１ｄに対応する部分を切除してから、該気密部材１１と既に配設されている断熱気密部材１０の端部同士を隙間なく密接させて、前述と同様に、気密部材１１の基部１１ａ及び下端部１１ｂが基礎１の内縁部Ｉを覆うように配置する。配置した後、気密テープ１３により、断熱気密部材１０と気密部材１１の基部１１ａ及び下端部１１ｂの連結部分を密封する。一方、気密部材１１同士の連結部分は、連結部分すべてに渡って気密テープ１３により密封する。従って、サッシ９両側に配設された断熱気密部材１０と前記気密部材１１とは、基部１１ａ及び下端部１１ｂにおいては連結部分が密封されているが、起立部１１ｃ及び上端部１１ｄにおいては密封されていない状態となっている。
【００５０】
気密部材１１を基礎１の内縁部Ｉに配置した後、図２１に示すように、端部用気密部材１６Ｒ、１６Ｌを、サッシ９両側の断熱気密部材１０に配設する。図２２は、端部用気密部材１６Ｒの詳細な構成を示すものであるが、該端部用気密部材１６は前記気密部材１１と同様に薄板状の合成樹脂が所定形状に成形されたものであって、図に示すように、水平方向の基部１６ａの手前側から下端部１６ｂが下方へ略直角に曲折されて垂下され、他方、奥側から起立部１６ｃが上方へ略直角に曲折されて立ち上がり、上端部１６ｄが起立部１６ｃから水平方向手前側へ略直角に曲折されている。さらに、前記基部１６ａ、起立部１６ｃ、及び上端部１６ｄの各左側端と直交するように、垂直方向に側端部１６ｅが形成されており、また、前記下端部１６ｂと略同形状の折返し部１６ｆが、基部１６ａの左側端から上方へ曲折されて前記側端部１６ｅの外側に重ねられ、これにより、端部用気密部材１６Ｒの左側端が封止されたようになっている。このように形成された端部用気密部材１６Ｒは、前記断熱気密部材１０の左端に配設されて、側端部１６ｅ及び折返し部１６ｆが、その後に配設される床帯板４８の側端を覆うものとなる。なお、端部用気密部材１６Ｌについては詳細に説明しないが、前記端部用気密部材１６Ｒと鏡対象の形状となっており、断熱気密部材１０の右端に配設されて、床帯板４８の側端を覆うものである。
【００５１】
このような形状の端部用気密部材１６Ｒ、１６Ｌを、サッシ９両側の各断熱気密部材１０の左端、右端に内接するように配設する。即ち、端部用気密部材１６Ｒ、１６Ｌの基部１６ａ、下端部１６ｂ、起立部１６ｃ、及び上端部１６ｄが、断熱気密部材１０の気密部材１１の基部１１ａ、下端部１１ｂ、起立部１１ｃ、及び上端部１１ｄと内接するように配置して、気密テープ１３等により適宜密封する。その後、断熱気密部材１０、気密部材１１、端部用気密部材１６Ｒ、１６Ｌの各下端部１１ｂ、１６ｂと基礎１の内側面とを密封するように防水気密テープ４０を貼り付ける。さらに、前述と同様に、和室用床パネル４５及び内壁枠受け下地４７を配設する。なお、サッシ９が配設された基礎１上には、内壁枠受け下地４７は配設しない。
【００５２】
つぎに、図２３に示すように、サッシ９が配設された基礎１上に床帯板４８を配設する。床帯板４８は、前記内壁枠受け下地４７の基台４７ａと略同厚みであって、和室用床パネル４５の縁部から気密部材１１の起立部１１ｃまでと略同幅の平板であり、気密部材１１の基部１１ａ上に配置してコンクリート釘等により基礎１に固定する。これにより、前記端部用気密部材１６Ｒ、１６Ｌは、内壁枠受け下地４７と床帯板４８とに夫々挟着されて、床帯板４８の側端を覆うものとなる。
【００５３】
床帯板４８を配設した後、図２４に示すように、気密部材１１の起立部１１ｃ及び上端部１１ｄを、前記床帯板４８を覆うように手前側に折り返し、その折返し部分、即ち起立部１１ｃ及び上端部１１ｄをタッカー等により床帯板４８に固定する。
【００５４】
その後、図２５に示すように、サッシ９に額縁４９を配設して、該額縁４９とサッシ９との間に断熱部材１５を充填する。これにより、前記気密部材１１の折返し部分は額縁４９の膳板４９ａと床帯板４８とによって挟着され、断熱部材１４は気密部材１１とサッシ９との間に介在して断熱ラインを形成する。これにより、図１９に示すように、サッシ９が配設された基礎１上に本断熱気密構造４００を構築することができる。
【００５７】
【発明の効果】
以上説明したように、本発明に係る断熱気密構造によれば、シート状の気密部材が、基礎上部の内縁部を覆い、且つ、サッシに沿って起立して、その上端部が床帯板の縁部を覆うように設けられ、前記気密部材の両側に、端部用気密部材が前記床帯板の側端を覆うように設けられ、前記気密部材の下端部と基礎の内側面とがシール部材により密封され、前記気密部材とサッシとの間に断熱部材が介設され、前記基礎上に、床帯板が設けられるとともに、その縁部が前記気密部材で覆われ、前記気密部材の上端部が、前記床帯板と膳板とによって挟着されたものとしたので、断熱気密ラインを簡易且つ確実に形成することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating and airtight structure of a building such as a house, and more particularly to a heat insulating and airtight structure constructed by a dry construction method on the inner wall of a room from the upper surface of a foundation.
[0002]
[Prior art]
In recent years, houses have been required to have heat insulation and airtightness in order to improve house comfort by systematic ventilation and to save energy by increasing the efficiency of air conditioning. Conventionally, there are various types of heat insulating and airtight structures for buildings such as houses, and these mainly perform heat insulation and airtightness so as to surround the entire internal space of the building.
[0003]
FIG. 26 shows a conventional heat-insulating and air-tight structure. As shown in FIG. 26, air-tight surfaces and heat-insulating surfaces are provided inside the indoor walls, ceiling, and floor of the building 91. The heat insulation airtight line 92 is constructed by making the surfaces continuous, and the heat insulation and airtightness of the internal space of the building are ensured. In this case, since the floor is usually ventilated, no consideration is given to heat insulation and airtightness.
[0004]
[Problems to be solved by the invention]
However, considerations for energy saving and environmental problems are increasing, and in order to further improve the efficiency of cooling and heating, a high level of heat insulation and airtightness of the house is required. For example, in a cold region, as shown in the figure, by arranging a heat insulating material on the outer periphery of the foundation 93, a heat insulation line 94 is formed outside the foundation 93, and the concrete of the foundation 93 becomes a heat bridge. It is suppressed and the heat insulation under the floor is improved. Thus, when ensuring the heat insulation line 94 in the foundation 93, it is preferable from a viewpoint of heat insulation and airtight reliability, and construction efficiency that an airtight line is also provided in the same location as a heat insulation line.
[0005]
Further, since the structure from the foundation to the inner wall of the room is complicated, the construction for forming the airtight surface and the heat insulating surface becomes complicated, and in particular, the dry construction method tends to cause a gap in the airtight surface. On the other hand, in the wet construction method in which urethane or the like is sprayed, it is difficult for gaps to be generated, but there are problems such as generation of chlorine-based gas and the need for a curing period.
[0006]
The present invention has been made in view of these points, and has a heat-insulating and air-tight structure capable of easily and reliably constructing a heat-insulating and air-tight line on the inner wall or sash of a room from the basic upper surface of a building such as a house. The purpose is to provide.
[0010]
[Means for Solving the Problems]
The heat insulating and airtight structure according to the present invention is:A heat-insulating and airtight structure in the sash of a Japanese-style room from the upper surface of the foundation of the building, in which a sheet-like airtight member covers the inner edge of the upper part of the foundation and rises along the sash, with the upper end of the floor strip It is provided so as to cover the edge, and an airtight member for an end is provided on both sides of the airtight member so as to cover a side end of the floor strip, and the lower end of the airtight member and the inner side surface of the foundation are sealed Sealed by a member, a heat insulating member is interposed between the airtight member and the sash, a floor strip is provided on the foundation, and an edge thereof is covered with the airtight member, and an upper end of the airtight member The portion is sandwiched between the floor strip and the gutter.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a heat-insulating and air-tight structure on the inner wall of a western-style room from the upper surface of the foundation according to the first embodiment of the present invention. On the upper part of the foundation 1 on which the heat insulating and airtight structure 100 is constructed, a shaft group 2 composed of C-shaped steel is assembled, a joist 3 is horizontally installed on the indoor side, and a floor panel 4 is laid thereon. Yes. An inner wall frame 5 having heat insulation and airtightness is erected on the edge of the floor panel 4, and an inner wall board 6 is disposed on the surface of the inner wall frame 5. On the other hand, an outer wall board 7 is disposed on the outdoor side, and a wall of the building is constructed by the inner wall frame 5, the inner wall board 6, and the outer wall board 7. Further, a base heat insulating member 8 made of foamed synthetic resin is disposed on the outer peripheral surface of the base 1 to insulate the base 1. In the structure of the upper portion of the foundation 1, the heat insulating and airtight structure 100 includes a heat insulating and airtight member 10 in which the airtight member 11 and the heat insulating member 12 are integrated, and the airtight member 11. Covers the inner edge of the foundation 1 and the edge of the floor panel 4, the lower end 11 b and the inner surface of the foundation 1 are sealed with waterproof and airtight tape 40, and the upper end 11 d of the floor panel 4 and the inner wall frame 5. The heat insulating member 12 is interposed between the airtight member 11 and the shaft assembly 2. Thereby, a heat insulating airtight line is formed from the upper part of the foundation 1 to the shaft set 2, the floor panel 4, and the inner wall frame 5.
[0012]
FIG. 2 shows an example of the heat-insulating and air-tight member 10. The heat-insulating and air-tight member 10 has a columnar heat-insulating member 12 fixed to the back surface of the air-tight member 11. An airtight tape 13 is attached to one end portion. The length in the longitudinal direction of the heat insulating and airtight member 10 is arbitrary, but about 1000 mm is preferable in consideration of the ease of molding and the convenience of construction.
[0013]
The airtight member 11 is a thin plate-like synthetic resin, and as shown in the drawing, the lower end portion 11b is bent downward at a substantially right angle from the horizontal base portion 11a, and the upright portion 11c is substantially upward. The upper end portion 11d is bent at a right angle and rises, and the upper end portion 11d is bent at a substantially right angle from the upright portion 11c to the front side in the horizontal direction. By arranging the heat insulating and airtight member 10 formed in this way on the upper part of the foundation 1, the base part 11 a and the lower end part 11 d cover the inner edge part of the foundation 1, that is, the upper surface and part of the inner side surface of the foundation 1, and stand up. The portion 11c and the upper end portion 11d cover the edge of the floor panel 4. In addition, since the airtight member 11 is bent in advance so as to match the edge of the floor panel 4 from the structural part where the heat-insulated airtight line is to be formed, that is, from the upper part of the foundation 1, the heat-insulating airtight member 10 is bent at the site. This eliminates the need to carry out the construction work and makes it difficult to create a gap due to a construction error or the like, thereby ensuring the desired airtightness. In addition, as for the synthetic resin which comprises the airtight member 11, what was excellent in airtight performance and waterproof performance, such as polyethylene, for example is suitable.
[0014]
The heat insulating member 12 is a columnar foam synthetic resin having substantially the same length as the airtight member 11, and is fixed to the back surface of the upright portion 11c of the airtight member 11 as shown in the figure. As the foamed synthetic resin constituting the heat insulating member 12, for example, a resin having excellent heat insulating performance such as foamed polystyrene and excellent moldability is suitable. The airtight member 11 and the heat insulating member 12 can be fixed by a well-known method. For example, even when the heat insulating member 12 is attached by using an adhesive such as an epoxy resin, the airtight member 11 is thermocompression bonded with the airtight member 11 during foam molding. Also good.
[0015]
The airtight tape 13 is a so-called pressure-sensitive adhesive tape, and is preferably one having excellent airtightness and waterproof performance, such as a polyethylene film or a polyethylene-aluminum laminate film. An adhesive is applied to the back surface of the hermetic tape 13 and a release paper is adhered thereto. About half of the hermetic tape 13 is peeled off, and the inner surface of one end of the hermetic member 11 is peeled off. The airtight member 11 is attached along the shape of the airtight member 11, and the remaining half of the airtight member 11 is protruded laterally from the airtight member 11 with the release paper attached. Therefore, when connecting the heat-insulating airtight member 10, the release paper of the airtight tape 13 is peeled off, and the portion of the airtight tape 13 protruding sideways is pasted on the inner surface of the airtight member 11 of the heat-insulating airtight member 10 to be connected. Just wear it.
[0016]
As described above, the heat insulating and airtight member 10 is interposed between the airtight member 11 formed according to the shapes of the foundation 1, the shaft assembly 2, and the floor panel 4, and the airtight member 11 and the shaft assembly 2. Since the heat insulating member 12 and the heat insulating member 12 are fixed in one piece in advance, the construction of the heat insulating and airtight structure 100 is simplified, and the airtight tape 13 is attached in advance to one end of the airtight member 11. Are connected to the upper portion of the foundation 1 so that the heat-insulating and air-tight members 10 can be easily brought into close contact with each other, and the airtightness of the connecting portion is also ensured.
[0017]
In addition, the said heat insulation airtight member 10 is an example, For example, what is arrange | positioned in the protruding corner part of the foundation 1 or a corner part is shape | molded previously so that it may correspond to the shape of a corner part or a corner part. . 3 and 4 show the heat-insulating and air-tight member 10A disposed at the exit corner and the heat-insulating and air-tight member 10B disposed at the entrance corner, respectively. In FIG. 2, the airtight member 11 and the heat insulating member 12 are bent at a substantially right angle toward the front of the figure so as to match the shape of the protruding corner. The length of the heat-insulating and air-tight member 10A is arbitrary, but considering the convenience of construction, it is preferable that each of the members bent at a substantially right angle is about 250 mm. On the other hand, in the heat insulating and airtight member 10B, the airtight member 11 has a shape bent at a substantially right angle to the other side of the figure, and the columnar heat insulating member 12 is fitted to the both side ends of the airtight member 11 so that the airtight member 11 is aligned. It is fixed on the back. The heat-insulating and air-tight member 10B covers only the corner portion of the entrance corner, and each bent at a substantially right angle is about 24 mm.
[0018]
As described above, the heat-insulating and air-tight members 10A and 10B to be disposed at the protruding corners and the entering corners have a complicated shape with a large number of bent portions. However, in the method of sealing the bent portion with an airtight tape or the like that are connected so as to be substantially at right angles, there is a disadvantage that a gap is easily generated in the connecting portion due to an error during cutting or bending of the airtight tape, and the airtight performance is reduced. In addition, there is a drawback that construction work increases. As described above, by using the heat-insulating and airtight members 10A and 10B that are preliminarily molded so as to match the shape of the protruding corner portion, the entering corner portion, etc., the airtight performance is maintained and the construction is facilitated.
[0019]
Further, as shown in FIG. 1, the heat insulating and airtight member 10 is disposed on the upper portion of the foundation 1, and the lower end portion 11 b of the airtight member 11 and the inner side surface of the foundation 1 are waterproof and airtight tape (seal member) 40. It is sealed by. The waterproof and airtight tape 40 is a well-known one used in a dry airtight construction method such as, for example, a synthetic resin and aluminum laminate film coated with an adhesive. On the other hand, the upper end 11 d of the airtight member 11 covers the edge of the floor panel 4, and the upper end 11 d is sandwiched between the floor panel 4 and the inner wall frame 5. Thereby, the heat insulation airtight line from the upper surface of the foundation 1 to the floor panel 4 is formed, and this heat insulation airtight line is connected to the heat insulation airtight line formed on the surface of the inner wall frame 5.
[0020]
Further, a waterproof spacer (seal member) 41 is adhered and sealed in the gap between the upper surface of the foundation 1 and the inner surface of the shaft assembly 2. The waterproof spacer 41 is preferably a soft foamed synthetic resin, aging resistant rubber, or the like. The waterproof spacer 41 may be directly attached with an adhesive or the like, or the waterproof and airtight tape 40 may be attached to the upper and lower ends thereof. Good. By sealing the gap between the foundation 1 and the shaft assembly 2 with the waterproof spacer 41 in this way, the airtightness and heat insulation of the heat insulation and airtight line are further enhanced, and rainwater and the like are prevented from entering through the gap. Is done.
[0021]
In addition, the structure of the building of the upper part of the foundation 1 shown in FIG. 1 is an example, and it is natural that the heat insulation airtight structure which concerns on this invention is not limited to the building structure of illustration. Therefore, for example, the foundation 1 is not limited to a C-type steel, regardless of the type such as a cloth foundation or a solid foundation.
[0022]
Hereinafter, the construction method of this heat insulation airtight structure 100 is demonstrated.
FIG. 5 is a diagram showing a planar shape of the foundation 1, but in the heat insulating and airtight structure 100, the heat insulating and airtight members 10 are sequentially arranged in a certain direction from the corner of the foundation 1 as in the protruding corner A.

Before disposing the heat-insulating and airtight member 10, first, as shown in FIG. 6, a waterproof spacer 41 is pasted over the upper surface of the foundation 1 and the inner surface of the shaft assembly 2. Seal the gap. When affixing the waterproof spacer 41, the upper surface of the foundation 1 is sufficiently cleaned to remove dust and the like. Further, the joint of the waterproof spacer 41 is sealed with a waterproof and airtight tape 40, and the protruding corner portion A and the input corner portion B and the like are attached to the waterproof spacer 41 with appropriate cuts. Seal with.
[0024]
Next, the heat insulating and airtight members 10, 10A, 10B are sequentially disposed. As shown in FIG. 7, the heat insulating and airtight member 10 </ b> A is first disposed at the protruding corner A. The heat insulating and airtight member 10A bent at a substantially right angle is aligned with the protruding corner portion A, and further, the base portion 11a and the lower end portion 11b of the airtight member 11 are disposed so as to cover the inner edge portion I of the upper portion of the foundation 1. Thereafter, as shown in the figure, a waterproof and airtight tape 40 is attached to a part of the lower end portion 11b and the inner surface of the foundation 1 to temporarily fix the heat insulating and airtight member 10A.
[0025]
After the heat insulating airtight member 10A is temporarily fixed to the protruding corner A, the heat insulating airtight member 10 is arranged in the right direction from the heat insulating airtight member 10A while being connected. In detail, the release paper of the airtight tape 13 of the airtight member 10 is peeled off, the ends of the heat insulating airtight members 10 and 10A are brought into close contact with each other without a gap, and the base portion 11a of the airtight member 11 is similar to the heat insulating airtight member 10A. And the lower end part 11b arrange | positions so that the inner edge part I of the foundation 1 may be covered. After the arrangement, the connecting portions of the heat insulating and airtight members 10 and 10 </ b> A are sealed with the airtight tape 13. In addition, although the direction which connects the heat insulation airtight member 10 sequentially may be either right direction or left direction, as shown in the figure, when the airtight tape 13 is stuck on the left side of the heat insulation airtight member 10 Assuming that the airtight tape 13 is connected to the right, the airtight tape 13 is affixed from the near side to the heat insulating airtight member 10A or the like that has already been disposed, and the workability is good.
[0026]
FIG. 8 shows the corner B, but the heat-insulating and air-tight members 10 are sequentially arranged. In the corner B, the unnecessary length of the heat-insulating and air-tight member 10 is matched with the N core of the foundation 1. The heat insulating airtight member 10 thus cut is disposed in the same manner as described above. Thereafter, the heat-insulating and air-tight member 10B is placed in close contact with the cut surface of the heat-insulating and air-tight member 10 and aligned with the corner B of the foundation 1. Similarly to the above, the heat-insulating and air-tight member 10B is also arranged so that the base 11a and the lower end 11b of the air-tight member 11 cover the inner edge I of the foundation 1, and the connecting portions of the heat-insulating and air-tight members 10 and 10B are sealed with the air-tight tape 13. To do.
[0027]
In this way, the heat insulating and airtight member 10 is continuously provided along the foundation 1 while keeping the heat insulating and airtight member 10A in the straight corner of the foundation 1, the heat insulating and airtight member 10A in the protruding corner, and the heat insulating and airtight member 10B in the entrance corner. Will be arranged.
[0028]
After the heat-insulating and air-tight members 10, 10A and 10B are arranged at predetermined positions, as shown in FIG. 9, the lower end portions 11b of the heat-insulating and air-tight members 10, 10A and 10B and the inner side surface of the foundation 1 are sealed.
