【０００１】
【発明の属する技術分野】
本発明は、例えば一戸建住宅等の屋外に設置される給湯器等の屋外機器から延びる送液用の配管等を、屋外と屋内とを仕切る外壁を貫通して配設するための壁貫通配管の壁貫通構造及び壁貫通配管の壁通し具に関する。
【０００２】
【従来の技術】
住宅の屋外に設置される給湯器に接続される配管を屋内へ引き込む技術として、特開平９−１０５４８２号公報の図３等に記載の技術が知られている。
【０００３】
この従来技術は、壁に通孔（設置穴）を設け、この通孔に屋外側から固定具を取付け、鞘管と、この鞘管の中に通される配管とからなる給湯管の一端を室内側の分配器（ヘッダー）に取付け、配管のみを固定具に通して屋外側の給湯器に取付けるものである。
【０００４】
この際、壁に固定具を取付け、分配器（ヘッダー）から固定具までは配管と鞘管とからなる給湯管を配設し、固定具の位置で鞘管を切断し、この切断された端部を固定具に当接させ、固定具の屋外側に斜め上向きに突出する止水部材に配管を通すことによって、この配管のみを壁に貫通させ、この配管の中間部を固定具に固定しており、屋外側に引き出された配管は給湯器に取付けられている。
【０００５】
【発明が解決しようとする課題】
前記従来技術は壁に対して配管を斜めに貫通させるので、この配管を壁の内外面に沿わす場合に配管への負荷が少なく、且つ、屋外側から配管を挿脱して更新できる点で優れている。
【０００６】
しかし、壁に対して屋外側に突出する斜状の止水部材とこれとは別の鞘管とは結合されていないので、これら止水部材と鞘管とに配管を通すときに鞘管又は止水部材の端部に配管の先端が当たって通しづらいと共に、屋外側から配管を通すときに鞘管が配管によって押し動かされ易いので、配管を通す作業性がよくないという問題がある。
【０００７】
本発明が解決しようとする課題は、外壁に鞘管を無理に曲げることなく沿わせて配設できると共に、配管を容易に通すことができる壁貫通配管の壁貫通構造及び壁貫通配管の壁通し具を得ることにある。
【０００８】
【課題を解決するための手段】
本発明の壁貫通配管の壁通し具は、外壁に対して直交する方向に沿って貫通する設置穴に嵌め込まれる筒部と、屋外に露出する前記筒部の一端部にこの筒部の内側を閉じて一体に設けられた閉塞部と、この閉塞部と一体に形成されるとともに前記筒部の外側に位置して前記閉塞部の上部から斜め上方に突出して、前記外壁を貫通する鞘管が挿入される筒状の鞘管ガイドと、前記設置穴から屋内側に突出される前記筒部の他端部に形成されたフランジ取付け部の外周に取付けられて、前記外壁の屋内側の面に接して固定されるフランジ部材と、を具備し、前記設置穴に嵌め込まれた前記筒部の他端部の下部側の縁部が前記設置穴内に位置されるとともに、前記筒部内で前記鞘管が座屈変形を起こさないで曲げられるように前記筒部の鉛直方向に沿う幅が前記鞘管の外径より大きく形成されていることを特徴とする。
【０００９】
本発明の壁貫通配管の壁通し具では、前記筒部の他端部の縁部が上方から下方に向かうにしたがって徐々に前記外壁の外面側に近づくように傾斜していることが好ましい。
【００１０】
本発明の壁貫通配管の壁通し具では、前記筒部の一端部の外周にねじ溝が設けられ、このねじ溝に螺合して前記一端部に取付けられるとともに、前記外壁を前記フランジ部材との間に挟んで前記外壁に固定される他のフランジ部材を備えることが好ましい。
【００１１】
本発明の壁貫通配管の壁通し具では、前記フランジ取付け部は、その外周に前記閉塞部からの距離が互いに異なる複数の凹溝を備え、前記外壁の厚みに応じて選択された前記凹溝に前記フランジ部材が係合されることが好ましい。
【００１２】
本発明の壁貫通配管の壁通し具では、前記凹溝が前記筒部の周方向に沿って形成されているとともに、前記フランジ部材が馬蹄形に形成されていることが好ましい。
【００１３】
本発明の壁貫通配管の壁通し具では、前記筒部の外周面と前記設置穴の内面と間を埋める止水パッキン又はコーキング材を備えることが好ましい。
【００１４】
本発明の壁貫通配管の壁通し具では、前記鞘管ガイドの先端部に屋外の配管と前記鞘管ガイドから突出された前記配管とを連結する継手部を備え、この継手部が、前記鞘管ガイドの先端面に当接する鍔部を有しかつ前記両配管が連結される継手と、前記鞘管ガイドの先端部に螺合されて前記鍔部を前記鞘管ガイドの先端面に押圧する継手固定部材とを備えていることが好ましい。
【００１５】
本発明の壁貫通配管の壁貫通構造は、既述の壁通し具を使用し、その筒部を外壁に対して直交する方向に沿って貫通する設置孔内に配置し、前記壁通し具の屋外側に突出した鞘管ガイド内に挿入された鞘管が、前記鞘管ガイドを起点として前記筒部内で座屈変形しないように曲げられているとともに、この鞘管内に前記外壁を貫通する配管が通されていることを特徴とする。
【００１６】
【発明の実施の形態】
以下、図１〜図４を参照して本発明の参考例に係る壁貫通配管の壁通し具を説明する。
【００１７】
図１は参考例の壁貫通配管の壁通し具１を一戸建の建屋の外壁２の設置穴３に取付けて、配管４及び鞘管５を貫通させた状態を示す断面図である。
【００１８】
図２（ａ）及び（ｂ）に示すように、この壁通し具１は第１壁通し部材６と第２壁通し部材７と連結手段とからなる。
【００１９】
合成樹脂製の第１壁通し部材６は、住宅の壁としての外壁２の厚み方向両面に夫々開放されていると共に上下方向に長い小判形をなして設けられた設置穴３に、屋外側から嵌め込む第１筒部８と、この第１筒部８と一体に形成されて外側に張り出し、設置穴３の屋外側縁部と引掛かり合う第１フランジ部１０と、第１筒部８の例えば屋外側端部に一体に形成されて第１筒部８の内側を閉じる閉塞部１２と、この閉塞部１２の下部に一体に形成されて屋内側から屋外側にかけて斜めに貫通する円筒形をなした鞘管ガイド１３とから構成される。なお、前記設置穴３は、外壁２に対して直交する方向に沿って、前記外壁２を貫通している。
【００２０】
鞘管ガイド１３はその屋内側端部が屋外側端部よりも上側に位置するように斜めに設けられ、したがって閉塞部１２の一端部から斜め下向きに突設されている。さらに、鞘管ガイド１３は後述する鞘管５を挿通できるように鞘管５よりやや大径となっている。使用状態において鞘管ガイド１３の屋内側端部は図３に示されるように設置穴３内に位置される。
【００２１】
周方向に連続すると共に例えば閉塞部１２と面一に連続した第１フランジ部１０の外壁２側には、第１壁通し部材６を設置穴３に設置したときに、第１フランジ部１０と外壁２との隙間を埋めて挟み込まれ雨水等の設置穴３への浸入を防止するための止水パッキン１４ａが設けられている。なお、前記隙間をコーキング処理する場合には止水パッキン１４ａは省略できる。
【００２２】
閉塞部１２には、この第１壁通し部材６と後述の第２壁通し部材７とを連結するための連結手段としてのねじ１５をねじ込むためのねじ通孔１６が第１筒部８の内側と貫通して設けられている。
【００２３】
合成樹脂製の第２壁通し部材７は、外壁２に設けられた設置穴３に、屋内側から嵌め込む第２筒部１７と、この第２筒部１７と一体に形成されて外側に張り出し、設置穴３の屋内側縁部と引掛かり合う第２フランジ部１９とからなる。周方向に連続する第２フランジ部１９の外壁２側には、第２壁通し部材７を設置穴３に設置したときに、第２フランジ部１９と外壁２との隙間を埋めて挟み込まれる止水パッキン１４ｂが設けられている。この止水パッキン１４ｂは省略してもよい。又、第２筒部１７の屋外側端部の内側には、連結手段としてのねじ１５を受け止めるためのねじ孔を有した螺合部２１が第１壁通し部材６のねじ通孔１６と対向する位置に設けられている。
【００２４】
壁通し具１が設置穴３に嵌め込まれるなどして取り付けられた際に、住宅の鉛直方向に沿う第１筒部８及び第２筒部１７の幅Ｄは、鞘管５の外径ｄの約２から３倍以上の寸法に形成されている。このように、第１筒部８及び第２筒部１７の幅Ｄは、鞘管５の外径ｄより十分大きく形成されている。
【００２５】
前記壁通し具１の具体的な寸法例を挙げると、呼び径が直径１３ｍｍの配管４を呼び径が直径２８ｍｍの鞘管５に通して、厚さ７５ｍｍの外壁２を貫通させる場合、外壁２を通る配管４及び鞘管５の外壁２に対する挿入角度が４５°となるように鞘管ガイド１３を閉塞部１２に対して設ける。又、このとき、設置穴３の口径の最も長い方向は長さ１５０ｍｍ以上が望ましい。又、図３に示すように、鞘管ガイド１３は鞘管５が貫通する際に接触する方向にのみ開口部があれば良く、正面から見て開口部は楕円形状でも構わない。この場合、配設に必要な壁裏空間２４は幅７０ｍｍ以上とする。
【００２６】
次に、外壁２への壁貫通配管の壁通し具１の取付け作業を説明する。
【００２７】
外壁２には予め前記第１、第２筒部８、１７の大きさに合わせて設置穴３が、屋外側と屋内側とを連通して外壁２に対して直交する方向に沿って貫通して開けられている。まず、第１壁通し部材６を取付ける。第１壁通し部材６の第１筒部８を設置穴３の屋外側から屋内側へ向かって、第１フランジ部１０が設置穴３の屋外側縁部に引掛かって止まるまで嵌め込む。このとき、第１フランジ部１０と外壁２の屋外側との隙間は、第１フランジ部１０の壁側に設けられた止水パッキン１４ａによって隙間無く塞がれる。
【００２８】
次に、第２壁通し部材７を取付ける。第１壁通し部材６の場合とは反対に、第２壁通し部材７の第２筒部１７を設置穴３の屋内側から屋外側へ向かって、第２フランジ部１９が設置穴３の屋内側縁部に引掛かって止まるまで嵌め込む。このとき、前述の第１壁通し部材６の場合と同様に、第２フランジ部１９と外壁２の屋内側との隙間は、第２フランジ部１９の壁側に設けられた止水パッキン１４ｂによって隙間無く塞がれる。それにより、設置穴３内で第１筒部８の屋内側端部と第２筒部１７の屋外側端部とが接近する。
【００２９】
この後、第１壁通し部材６の閉塞部１２のねじ通孔１６を通して、屋外側からねじ１５を第２壁通し部材７の螺合部２１にねじ込むことで、第１壁通し部材６と第２壁通し部材７とを連結すると共に、止水パッキン１４ａ、１４ｂが外壁２の内外両壁面に夫々圧接される。以上で外壁２の設置穴３への壁貫通配管の壁通し具１の取付けが終了する。
【００３０】
この参考例の壁貫通配管の壁通し具１は第１壁通し部材６と第２壁通し部材７とをねじ１５により連結しているだけなので、将来この壁貫通配管の壁通し具１を取り外す必要が生じたときには、ねじ１５を緩めて外すだけで、外壁２の設置穴３からこの壁貫通配管の壁通し具１を取り外すことができる。
【００３１】
次に、例えば給湯又は給水のための送液用の配管４及び鞘管５を、前述のようにして外壁２の設置穴３に取付けた壁貫通配管の壁通し具１に通す配設作業を説明する。配管４は架橋ポリエチレン管であって可撓性を有し、この配管４が通される鞘管５は配管４よりも硬質な合成樹脂製ではあるが、可撓性に優れた波付け管が採用されている。
【００３２】
鞘管５は、例えば屋外から屋内へと通される。すなわち、鞘管５の一端を第１壁通し部材６の鞘管ガイド１３に屋外側から斜め上向きに通していく。図３及び図４（ａ）、（ｂ）に示されるように、鞘管ガイド１３はこの屋内側端部が屋外側端部よりも上側に在るように閉塞部１２を斜めに貫通して設けられているため、鞘管ガイド１３を通して屋外から屋内へと通された鞘管５は、壁通し具１をその第２壁通し部材１６に引掛かることなく斜め上向きに通り抜けて外壁２の屋内側壁面に沿って上方へと押し込まれるから、図１に示されるように、外壁２と部屋の内装板２３とによって作られる幅の狭い壁裏空間２４や、部屋の天井２５の上の屋根裏空間２６にも無理に折り曲げられて座屈変形を起こすことなく配設できる。配設し終わった鞘管５は、外壁２等に適当な間隔に取付けられるＵ字形をなしたサドル２７等を用いてずれ落ちないように固定される。
【００３３】
次に、壁通し具１を斜めに貫通して鞘管ガイド１３に中間部が支持された鞘管５に対して、屋外より配管４を斜め上向きに挿入することによって、この配管４を鞘管５に沿わせて配設する。鞘管５は無理に折り曲げられることなく既に必要とされる所定の位置まで配設されているので、配管４は、無理に折り曲げられて座屈変形を起こすことなく鞘管５の内部を通って所定の位置まで案内される。鞘管５の配設及び固定作業の終了後に、図３に示すように、鞘管ガイド１３の屋外側の開口部において、コーキング材２８による止水処理を施して鞘管５と開口部との隙間を塞ぐ。この止水処理によって、鞘管ガイド１３を通して屋外から屋内へ雨水等が浸入するおそれを極めて低くできる。なお、コーキング処理に代えて鞘管ガイド１３と鞘管５との間にＯリングを挟んでもよく、又、これら両止水処理を兼用してもよい。
【００３４】
又、屋外側の鞘管５の他端は外壁２の屋外側に設置されたシステムアジャスタ支え２９によって支持されたシステムアジャスタ３０に接続される。配管４が通るシステムアジャスタ３０は伸縮自在の蛇腹部３１を有しており、鞘管５の屋外に露出している部分の長さに適合した高さに伸び縮みできる。又、システムアジャスタ３０の下端を受けるピン付オスアダプタ３３には継手３２を介して配管４が接続されている。このアダプタ３３は屋外に設置された給湯器３４に連結されていて、給湯器３４の温水等が導かれる。
【００３５】
以上、説明した壁貫通配管の壁通し具１を用いた配管４及び鞘管５の配設作業によれば、外壁２に対して斜めに設けられた鞘管ガイド１３に鞘管５を通すことで、外壁２の壁面に沿うように鞘管５を屋内へと配設する。第１筒部８及び第２筒部１７の鉛直方向に沿った幅Ｄが、鞘管５の外径ｄより十分大きく形成されているので、鞘管５が無理に折り曲げられて座屈変形を起さない十分に広い空間Ｓを、第１筒部８及び第２筒部１７内に確保できる。また、外壁２に対して斜めに設けられた鞘管ガイド１３に鞘管５を通すことで、外壁２の壁面に沿うように鞘管５を屋内へと配設できる。
【００３６】
したがって、外壁２の屋内側の狭い壁裏空間内においても鞘管５を無理に折り曲げて座屈変形を起こさせることがない。このため、鞘管５の内部に通して屋外から屋内へと配設する配管４も無理に折り曲げて座屈変形を起こさせることなく、容易に配設できる。さらに、屋外側より配管４を斜め下方に引っ張ることにより、挿入時と同様に鞘管５をガイドとして少ない抵抗で容易に配管４を引き出せるので、こうした配管４の出し入れ操作によって、将来において配管４が老朽化した場合の配管４の更新作業も簡単に行うことができる。
【００３７】
又、壁貫通配管の壁通し具１の位置において鞘管５は途切れることなく屋外から屋内へと連続して配設されている。このため、屋内で配管４から水が漏れ出しても鞘管５の内部を伝わって屋外へと排出されるので、屋内への浸水のおそれが低い。しかも、鞘管５及び配管４が外壁２を貫通しており、配管４に対する継手部分は外壁２の屋外側にあるので、漏水し易い継手部分からの漏水があっても屋内への浸水のおそれがない。
【００３８】
又、鞘管ガイド１３はこの屋内側が屋外側よりも上側に位置するように閉塞部１２を斜めに貫通して設けられているので、雨水等が斜め下向きの鞘管ガイド１３を通って屋外から屋内へと浸入するおそれが殆どない。加えて、この鞘管ガイド１３の屋外側の開口部にコーキング材２８等による止水処理を施して鞘管５と開口部との隙間を塞いだので、より一層のこと浸水のおそれがない。
【００３９】
又、第１、第２フランジ部１０、１９及びそれらに夫々設けられた止水パッキン１４ａ、１４ｂによって、外壁２の両側から設置穴３を隙間なく挟み込むサンドイッチ構造をとっているので、簡単に止水処理ができると共に、設置穴３と壁通し具１との間の埋め戻し作業等の閉栓処理も不要にでき、施工性がよい。
【００４０】
又、設置穴３への壁通し具１の取付け作業と、屋内における配管４及び鞘管５の配設作業の順序はどちらが先でも構わない。又、プレハブ住宅の場合には壁通し具１を外壁２に予め取付けておくことができるから、その場合には建築現場での壁通し具１の取付けが不要であり、容易に配設作業を行うことができる。
【００４１】
又、壁通し具１は正面から見た形状が上下方向に沿って長い小判形となっていて小型であるため、外壁２に設けられた設置穴３も正面から見た形状を同様の小判形とできるので、大きな円形の穴を外壁２に設ける必要がなく、設置穴３を設けることによる外壁２の強度の低下を抑制できる。
【００４２】
次に、図５から図７を参照して本発明の第１の実施の形態に係る壁貫通配管の壁通し具１を説明する。なお、前述した参考例に係る壁貫通配管の壁通し具１と同一構成部分には、同一符号を付して説明を省略する。
【００４３】
本実施の形態の壁通し具１が取付けられる設置穴３は、外壁２に対し直交する方向に沿って、この外壁２を貫通している。設置穴３は丸形に形成されている。また、本実施形態の壁通し具１は、屋外Ｏから屋内Ｉに向うにしたがって上方から下方に向って給湯器などから供給される湯を導くために用いられる。
【００４４】
図５から図７に示すように、本実施形態の壁貫通配管の壁通し具１は、第１壁通し部材６だけで構成されている。本実施形態の第１壁通し部材６は、その第１筒部８が円筒状に形成されている。第１筒部８はその軸線Ｐが、壁通し具１が設置穴３に取付けられた際に、外壁２に対し直交する方向に沿う。
【００４５】
壁通し具１が設置穴３に取付けられた際に、第１筒部８の鉛直方向に沿った幅Ｄは、鞘管５の外径ｄの約２から３倍以上の寸法に形成されている。第１筒部８の鉛直方向に沿った幅Ｄは、鞘管５の外径ｄより十分大きく形成されている。また、第１壁通し部材６は、壁通し具１が設置穴３に取付けられた際に、第１筒部８の屋外Ｏ側に露出する一端部８ａに閉塞部１２を設けている。
【００４６】
鞘管ガイド１３は、前記閉塞部１２から屋外Ｏ側でかつ斜め上方に向って突出して形成されている。鞘管ガイド１３は、前記軸線Ｐより上方に位置する閉塞部１２の端部から突出している。第１筒部８の内側において鞘管ガイド１３と閉塞部１２との接合部には、滑らかに湾曲した湾曲面１１０が形成されている。鞘管ガイド１３は閉塞部１２の内面１２ａより第１筒部８の内側には突出していない。
【００４７】
第１筒部８の外周面には、全周に亘って止水パッキン１４が設けられている。この止水パッキン１４は、第１筒部８と設置穴３の内面との間の隙間Ｇを埋めて、この隙間Ｇを通る雨水などの屋内Ｉへの浸入を防止する。止水パッキン１４の代わりに周知のコーキング材を用いて前記隙間Ｇを埋めるようにしても良い。
【００４８】
鞘管ガイド１３の屋内Ｉ側に位置する他端部８ｂには、フランジ取付け部１１１が形成されている。このフランジ取付け部１１１には、設置穴３の穴縁に引掛るフランジ部材１１２が取付けられるようになっている。
【００４９】
フランジ取付け部１１１は、第１筒部８の外周面に形成されかつこの外周面から凹に形成された凹溝１１３を複数備えている。図示例において、フランジ取付け部１１１は、凹溝１１３を二つ備えている。それぞれの凹溝１１３は、前記他端部８ｂのうち少なくとも前記軸線Ｐより鞘管ガイド１３が設けられた側の外周面に、第１筒部８の周方向に沿って形成されている。それぞれの凹溝１１３は、壁通し具１が設置穴３に取付けられた際に、外壁２に沿うように形成されている。
【００５０】
それぞれの凹溝１１３は、前記閉塞部１２の表面１２ｂからの距離が壁通し具１が取付けられる外壁２の厚みに応じた位置に形成されるのが望ましい。凹溝１１３は、前記閉塞部１２の表面１２ｂからの距離が互いに異なる位置に形成されている。また、それぞれの凹溝１１３は、前記他端部８ｂのうち軸線Ｐより鞘管ガイド１３が配置されていない側の外周面には形成されていない。
【００５１】
フランジ部材１１２は、馬蹄形に形成されているとともに、凹溝１１３に係合するようになっている。フランジ部材１１２は、壁通し具１が設置穴３内に嵌め込まれた際に、上方から凹溝１１３に係合する。フランジ部材１１２は、凹溝１１３に係合すると、その端面が設置穴３の穴縁に引っ掛る。
【００５２】
フランジ部材１１２には、複数の貫通穴１１４が形成されている。これらの貫通穴１１４には、それぞれ、フランジ部材１１２を外壁２に固定するねじ１１５が通るようになっている。
【００５３】
第１筒部８は、その他端部８ｂの縁部８ｃが上方から下方に向うにしたがって即ち鞘管ガイド１３から離れるのにしたがって、徐々に外壁２の外面側に近づく方向に傾斜するように形成されている。この他端部８ｂにおいて、前記軸線Ｐより鞘管ガイド１３が設けられた側の縁部８ｃは、外壁２から屋内Ｉ側に突出しているとともに、軸線Ｐより鞘管ガイド１３が配置されていない側の縁部８ｃは、設置穴３の穴縁より設置穴３内に位置するように形成されている。
【００５４】
前記壁通し具１の具体的な寸法例を示す。前記設置穴３は外壁２の機械的な強度を極力低下させないため、その直径を極力小さく形成するのが望ましい。呼び径が直径１３ｍｍの配管４を呼び径が直径２８ｍｍの鞘管５に通して、厚さ７５ｍｍから１００ｍｍの外壁２を貫通させる場合、外壁２を通る配管４及び鞘管５の前記軸線Ｐに対する挿入角度θ´が２３°となるように鞘管ガイド１３を閉塞部１２に対して設ける。又、このとき、設置穴３の口径は、直径１００ｍｍに形成されるのが望ましい。
【００５５】
次に、この第１の実施の形態の壁通し具１の外壁２の設置穴３への取付け作業を説明する。
【００５６】
まず、第１壁通し部材６を、閉塞部１２が屋外Ｏに露出するように、屋外Ｏ側から設置穴３内に嵌め込む。外壁２の厚みに応じた凹溝１１３にフランジ部材１１２を上方から係合させる。ねじ１１５を貫通穴１１４内に通して外壁２にねじ込んで、フランジ部材１１２とともに第１壁通し部材６を外壁２に固定する。このとき、第１筒部８と設置穴３との間の隙間Ｇは、止水パッキン１４によって全周に亘って隙間なく埋められる。以上で外壁２の設置穴３への第１の実施の形態の壁貫通配管の壁通し具１の取付けが終了する。
【００５７】
壁通し具１を外壁２に固定した後、屋内Ｉ側から鞘管５及び配管４を順次、鞘管ガイド１３内に挿入する。鞘管ガイド１３の先端部１３ａから突出した配管４の端部に、継手３２を介して、２階などの上方に設置された給湯器に連結した配管１１６を連結する。この連結を行なう際に、図示例では以下に示す継手部１１７を用いる。
【００５８】
継手部１１７は、前記継手３２と、鞘管ガイド１３の先端部１３ａの外周に形成されたねじ溝１１８と、このねじ溝１１８に螺合する継手固定部材１１９などを備えている。前記継手３２は、金属からなりかつ鞘管ガイド１３の開口縁１３ｂと当接する鍔部１２０を一体に備えている。鍔部１２０は、継手３２の全周に亘って設けられている。
【００５９】
継手固定部材１１９は、合成樹脂などからなりかつその内周に継手３２が通ることが可能な円環状に形成されている。継手固定部材１１９は、円筒状に形成されかつ鞘管ガイド１３のねじ溝１１８に螺合するねじ部１２１と、このねじ部１２１の一端から内周側に向って延びた円環状の円環部１２２と、を一体に備えている。この円環部１２２は、ねじ部１２１がねじ溝１１８に螺合すると継手３２の鍔部１２０を鞘管ガイド１３の開口縁１３ｂに向かって押圧する。
【００６０】
このように、継手部１１７は、継手固定部材１１９が鞘管ガイド１３のねじ溝１１８に螺合して、継手３２の鍔部１２０を鞘管ガイド１３の開口縁１３ｂに向かって押圧することによって、鞘管ガイド１３の開口部を雨水が入らないように閉じている。
【００６１】
本実施形態によれば、設置穴３内に嵌め込まれた際に第１筒部８の鉛直方向に沿った幅Ｄが、鞘管５の外径ｄより十分大きく形成されているので、鞘管５が無理に折り曲げられて座屈変形を起さない十分に広い空間Ｓを第１筒部８内に確保できる。さらに、第１筒部８の屋内Ｉ側に位置する他端部８ｂのうち軸線Ｐより鞘管ガイド１３が配置されていない側の縁部８ｃが設置穴３の穴縁より設置穴３内に位置している。
【００６２】
このため、外壁２の裏側空間が狭い場合でも、鞘管５が無理に曲げることなく外壁２を貫通させてこの外壁２に沿って配設されることとなる。また、鞘管５が無理に曲げられることがないため、この鞘管５内に容易に配管４を通すことができる。
【００６３】
また、この壁貫通配管の壁通し具１が取り付けられる設置穴３が、外壁２に対して直交する方向に沿って貫通しているので、雨水などが第１筒部８の外表面などを伝わって屋内に侵入することを防止できる。本実施形態において、前記設置穴３は、屋外Ｏから屋内Ｉに向かうにしたがって、徐々に上方に向かうように外壁２を貫通するように形成されても良い。この場合、雨水の浸入をより一層防止できる。なお、このとき、第１筒部８は、その軸線Ｐが屋外Ｏから屋内Ｉに向かうにしたがって徐々に下方に向かうように傾いて、形成されるのが望ましい。
【００６４】
さらに、配管４と、給湯器などに連結した配管１１６とを互いに連結する継手３２が、屋外Ｏに位置することとなる。また、鞘管５は、鞘管ガイド１３の中ほどまで挿入されている。このため、たとえ、この継手３２に水漏れが生じても屋内Ｉへの浸水を防止できる。
【００６５】
また、フランジ部材１１２が外壁２にねじ１１５などによって固定されている。このため、鞘管ガイド１３に新規に鞘管５及び配管４を通すときは勿論のこと、老朽化した配管４などを新品と交換するときにおいても、配管４や鞘管５を鞘管ガイド１３内に通す際等に加わる操作力を、フランジ部材１１２に波及させて外壁２で分散して支持できる。
【００６６】
このため、壁通し具１が外壁２などから不用意に外れることを防止できる。したがって、配管４の出し入れに拘わらず外壁２への鞘管５の設置状況を確実に保持することができる。
【００６７】
さらに、フランジ取付け部１１１が、閉塞部１２の表面１２ｂからの距離が互いに異なる凹溝１１３を複数備えている。このため、外壁２の厚みに応じて、フランジ部材１１２を係合させる凹溝１１３を任意に選択することによって、互いに異なる厚みの外壁２に形成された設置穴３へも、容易に取付けることができる。
【００６８】
なお、この例では、鞘管ガイド１３の内面中ほどに突設したストッパ１３ｄまで鞘管５を挿入するようになっているが、鞘管５は鞘管ガイド１３の外まで引出されても良い。この場合、配管４も鞘管ガイド１３の外に引出される。このようにすれば、配管４と配管１１６との接続部から水漏れが生じたときの屋内Ｉへの浸水をより高度に防止できる。
【００６９】
次に、図８を参照して本発明の第２の実施の形態に係る壁貫通配管の壁通し具１を説明する。なお、前述した第１の実施の形態に係る壁貫通配管の壁通し具１と同一構成部分には、同一符号を付して説明を省略する。

【００７１】
第２実施形態の壁通し具１を設置穴３に取付ける際には、予め、第２のフランジ部材１３０を第１筒部８に取付けておく。この第２のフランジ部材１３０が取付けられた第１筒部８を設置穴３内に嵌め込む。そして、前述した第９の実施の形態の壁通し具１と同様の方法で、外壁２に固定するとともに、配管４と、給湯器などと連結した配管１１６と、を互いに連結する。

第２実施形態によれば、前述した第１の実施の形態の壁通し具１の効果にくわえ、外壁２をフランジ部材１１２と第２のフランジ部材１３０とによって挟み込んだ状態で取付けられている。このため、配管４や鞘管５を鞘管ガイド１３内に通す際等に加わる操作力を、フランジ部材１１２及び第２のフランジ部材１３０に波及させて外壁２でより分散して支持できる。
【００７３】
このため、壁通し具１が外壁２などから不用意に外れることをより確実に防止できる。したがって、配管４の出し入れに拘わらず外壁２への鞘管５の設置状況をより確実に保持できる。
【００７４】
さらに、第２のフランジ部材１３０の第１筒部８へのねじ込み量を調整することによって、互いに異なる厚みの外壁２に形成された設置穴３へも、より容易に取付けることができる。したがって、互いに異なる厚みの外壁２への設置性がより向上する。

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, the present invention will be described with reference to FIGS.Reference exampleThe wall threading tool of the wall through pipe according to the above will be described.
[0017]
  Figure 1Reference exampleIt is sectional drawing which shows the state which attached the wall through tool 1 of the wall penetration piping of this to the installation hole 3 of the outer wall 2 of a detached building, and penetrated the piping 4 and the sheath tube 5. FIG.
[0018]
  As shown in FIGS. 2A and 2B, the wall threading tool 1 includes a first wall threading member 6, a second wall threading member 7, and a connecting means.
[0019]
  The first wall-passing member 6 made of synthetic resin is opened from the outdoor side to the installation holes 3 that are open on both sides in the thickness direction of the outer wall 2 as a house wall and are formed in a long oval shape in the vertical direction. A first tube portion 8 to be fitted, a first flange portion 10 that is formed integrally with the first tube portion 8 and projects outward, and engages with an outdoor side edge of the installation hole 3; For example, a closed portion 12 that is integrally formed on the outdoor side end portion and closes the inside of the first cylindrical portion 8, and a cylindrical shape that is integrally formed at the lower portion of the closed portion 12 and that obliquely penetrates from the indoor side to the outdoor side. And a formed sheath guide 13. The installation hole 3 penetrates the outer wall 2 along a direction orthogonal to the outer wall 2.
[0020]
  The sheath tube guide 13 is provided obliquely so that the indoor side end thereof is located above the outdoor side end, and thus protrudes obliquely downward from one end of the closed portion 12. Furthermore, the sheath tube guide 13 has a slightly larger diameter than the sheath tube 5 so that the sheath tube 5 described later can be inserted. In the use state, the indoor side end of the sheath guide 13 is positioned in the installation hole 3 as shown in FIG.
[0021]
  When the first wall threading member 6 is installed in the installation hole 3 on the outer wall 2 side of the first flange portion 10 that is continuous in the circumferential direction and is flush with the closing portion 12, for example, A water stop packing 14a is provided to prevent the rainwater or the like from entering the installation hole 3 by being filled with a gap with the outer wall 2. In addition, when the said clearance gap is caulk-processed, the water stop packing 14a is omissible.
[0022]
  The closing portion 12 has a screw through hole 16 for screwing a screw 15 as a connecting means for connecting the first wall passing member 6 and a second wall passing member 7 to be described later on the inside of the first tube portion 8. And is provided through.
[0023]
  The second wall-passing member 7 made of synthetic resin is formed integrally with the second cylindrical portion 17 fitted into the installation hole 3 provided in the outer wall 2 from the indoor side, and projects outward from the second cylindrical portion 17. The second flange portion 19 catches the indoor side edge portion of the installation hole 3. On the outer wall 2 side of the second flange portion 19 that is continuous in the circumferential direction, when the second wall passing member 7 is installed in the installation hole 3, the gap between the second flange portion 19 and the outer wall 2 is filled and sandwiched. A water packing 14b is provided. This water blocking packing 14b may be omitted. Further, on the inner side of the outdoor side end portion of the second cylindrical portion 17, a screwing portion 21 having a screw hole for receiving the screw 15 as a connecting means is opposed to the screw hole 16 of the first wall passing member 6. It is provided in the position to do.
[0024]
  When the wall threading tool 1 is attached by being fitted into the installation hole 3 or the like, the width D of the first tube portion 8 and the second tube portion 17 along the vertical direction of the house is the outer diameter d of the sheath tube 5. The size is about 2 to 3 times or more. Thus, the width D of the first cylinder portion 8 and the second cylinder portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5.
[0025]
  As a specific example of the dimensions of the wall threading tool 1, when the pipe 4 having a nominal diameter of 13 mm is passed through the sheath pipe 5 having a nominal diameter of 28 mm and penetrated through the outer wall 2 having a thickness of 75 mm, the outer wall 2 The sheath pipe guide 13 is provided with respect to the closing portion 12 so that the insertion angle of the pipe 4 and the sheath pipe 5 passing through the outer wall 2 with respect to the pipe 4 is 45 °. At this time, the longest diameter of the installation hole 3 is preferably 150 mm or more. Further, as shown in FIG. 3, the sheath tube guide 13 only needs to have an opening in a direction in which the sheath tube 5 contacts when penetrating, and the opening may be elliptical when viewed from the front. In this case, the wall space 24 necessary for the arrangement is set to have a width of 70 mm or more.
[0026]
  Next, an operation of attaching the wall threading tool 1 of the wall through pipe to the outer wall 2 will be described.
[0027]
  The outer wall 2 is provided with an installation hole 3 in advance according to the size of the first and second cylindrical portions 8 and 17.Along the direction orthogonal to the outer wall 2 through communication between the outdoor side and the indoor sideIt is opened through. First, the first wall passing member 6 is attached. The first tubular portion 8 of the first wall passing member 6 is fitted from the outdoor side of the installation hole 3 toward the indoor side until the first flange portion 10 is hooked on the outdoor side edge of the installation hole 3 and stops. At this time, the gap between the first flange portion 10 and the outdoor side of the outer wall 2 is closed without a gap by the water stop packing 14 a provided on the wall side of the first flange portion 10.
[0028]
  Next, the second wall passing member 7 is attached. Contrary to the case of the first wall passing member 6, the second flange portion 19 is located in the installation hole 3 when the second tube portion 17 of the second wall passing member 7 is directed from the indoor side to the outdoor side of the installation hole 3. Fit on the inner edge until it stops. At this time, as in the case of the first wall passing member 6 described above, the gap between the second flange portion 19 and the indoor side of the outer wall 2 is caused by the water stop packing 14b provided on the wall side of the second flange portion 19. It is closed without a gap. Thereby, the indoor side end of the first cylinder part 8 and the outdoor side end part of the second cylinder part 17 approach in the installation hole 3.
[0029]
  Thereafter, the screw 15 is screwed from the outdoor side into the screwing portion 21 of the second wall passing member 7 through the screw through hole 16 of the closing portion 12 of the first wall passing member 6, thereby the first wall passing member 6 and the first wall passing member 6 are connected to the first wall passing member 6. The two-wall through member 7 is connected, and the water-stopping packings 14a and 14b are pressed against the inner and outer wall surfaces of the outer wall 2, respectively. Thus, the attachment of the wall threading tool 1 of the wall through pipe to the installation hole 3 of the outer wall 2 is completed.
[0030]
  thisReference exampleSince the wall threading tool 1 of the wall through pipe of the present invention simply connects the first wall threading member 6 and the second wall threading member 7 with screws 15, it is necessary to remove the wall threading tool 1 of this wall through pipe in the future. In such a case, the wall threading tool 1 of the wall through pipe can be removed from the installation hole 3 of the outer wall 2 simply by loosening and removing the screw 15.
[0031]
  Next, for example, an arrangement operation is performed in which the liquid supply pipe 4 and the sheath pipe 5 for hot water supply or water supply are passed through the wall through tool 1 of the wall through pipe attached to the installation hole 3 of the outer wall 2 as described above. explain. The pipe 4 is a cross-linked polyethylene pipe and has flexibility, and the sheath pipe 5 through which the pipe 4 passes is made of a synthetic resin harder than the pipe 4, but a corrugated pipe having excellent flexibility is used. It has been adopted.
[0032]
  The sheath tube 5 is passed from the outside to the inside, for example. That is, one end of the sheath tube 5 is passed obliquely upward from the outdoor side through the sheath tube guide 13 of the first wall passing member 6. As shown in FIGS. 3 and 4 (a) and 4 (b), the sheath tube guide 13 obliquely penetrates the closed portion 12 so that the indoor side end portion is located above the outdoor side end portion. Therefore, the sheath tube 5 passed from the outside to the inside through the sheath guide 13 passes through the wall threading tool 1 obliquely upward without being caught by the second wall threading member 16, and the outer wall 2 is closed. Since it is pushed upward along the inner wall surface, as shown in FIG. 1, a narrow wall space 24 formed by the outer wall 2 and the interior board 23 of the room, or an attic space above the ceiling 25 of the room. 26 can be arranged without being bent by force and causing buckling deformation. The sheath tube 5 that has been disposed is fixed so as not to fall off using a U-shaped saddle 27 or the like attached to the outer wall 2 or the like at an appropriate interval.
[0033]
  Next, it penetrates through the wall threading tool 1 diagonally to the sheath guide 13.The middle partThe pipe 4 is disposed along the sheath pipe 5 by inserting the pipe 4 obliquely upward from the outside with respect to the supported sheath pipe 5. Since the sheath pipe 5 is disposed to a predetermined position that is already necessary without being bent excessively, the pipe 4 passes through the inside of the sheath pipe 5 without being bent and causing buckling deformation. Guided to a predetermined position. After the sheath tube 5 is disposed and fixed,FIG.As shown in FIG. 5, the water-stop treatment by the caulking material 28 is performed at the outdoor side opening of the sheath tube guide 13 to close the gap between the sheath tube 5 and the opening. By this water stop treatment, the risk of rainwater or the like entering from the outside to the inside through the sheath guide 13 can be extremely reduced. In place of the caulking process, an O-ring may be sandwiched between the sheath tube guide 13 and the sheath tube 5, or both water stop treatments may be used together.
[0034]
  The other end of the outdoor sheath tube 5 is connected to a system adjuster 30 supported by a system adjuster support 29 installed on the outdoor side of the outer wall 2. The system adjuster 30 through which the pipe 4 passes has an expandable / contractible bellows portion 31 and can expand and contract to a height suitable for the length of the portion exposed to the outside of the sheath tube 5. A pipe 4 is connected to a male adapter 33 with a pin that receives the lower end of the system adjuster 30 via a joint 32. The adapter 33 is connected to a water heater 34 installed outdoors, and hot water or the like of the water heater 34 is guided.
[0035]
  As described above, according to the arrangement work of the pipe 4 and the sheath pipe 5 using the wall through tool 1 of the wall penetration pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 13 provided obliquely with respect to the outer wall 2. Thus, the sheath tube 5 is disposed indoors along the wall surface of the outer wall 2. Since the width D along the vertical direction of the first tube portion 8 and the second tube portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5, the sheath tube 5 is forcibly bent to cause buckling deformation. A sufficiently wide space S that does not occur can be secured in the first tube portion 8 and the second tube portion 17. Further, the sheath tube 5 can be placed indoors along the wall surface of the outer wall 2 by passing the sheath tube 5 through the sheath tube guide 13 provided obliquely with respect to the outer wall 2.
[0036]
  Therefore, even in the narrow wall space on the indoor side of the outer wall 2, the sheath tube 5 is not forcibly bent to cause buckling deformation. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with little resistance using the sheath pipe 5 as a guide as in the case of insertion. The work of updating the pipe 4 when it is aged can be easily performed.
[0037]
  Further, the sheath tube 5 is continuously arranged from the outside to the indoor without interruption at the position of the wall threading tool 1 of the wall through pipe. For this reason, even if water leaks out from the pipe 4 indoors, the water travels through the inside of the sheath pipe 5 and is discharged to the outside. And since the sheath pipe 5 and the piping 4 have penetrated the outer wall 2, and the joint part with respect to the pipe 4 exists in the outdoor side of the outer wall 2, even if there is a leak from the joint part which is easy to leak, there is a possibility of flooding indoors There is no.
[0038]
  Further, since the sheath guide 13 is provided obliquely through the closed portion 12 so that the indoor side is located above the outdoor side, rainwater or the like passes through the sheath guide 13 obliquely downward from the outside. There is almost no risk of entering indoors. In addition, since the opening on the outdoor side of the sheath tube guide 13 is subjected to water-stopping treatment with the caulking material 28 or the like to close the gap between the sheath tube 5 and the opening, there is no further possibility of flooding.
[0039]
  In addition, since the first and second flange portions 10 and 19 and the water-stopping packings 14a and 14b provided on the flange portions 10 and 19 respectively have a sandwich structure in which the installation holes 3 are sandwiched from both sides of the outer wall 2 without gaps, Water treatment can be performed, and plugging processing such as backfilling work between the installation hole 3 and the wall threading tool 1 can be made unnecessary, and workability is good.
[0040]
  Further, the order of the work of attaching the wall threading tool 1 to the installation hole 3 and the work of arranging the pipe 4 and the sheath pipe 5 indoors may be first. In the case of a prefabricated house, the wall threading tool 1 can be attached to the outer wall 2 in advance. In this case, the wall threading tool 1 is not required to be installed at the construction site. It can be carried out.
[0041]
  Further, since the shape of the wall threading tool 1 as viewed from the front is an oval shape that is long in the vertical direction and is small, the installation hole 3 provided in the outer wall 2 also has the same oval shape as viewed from the front. Therefore, it is not necessary to provide a large circular hole in the outer wall 2, and a decrease in strength of the outer wall 2 due to the installation hole 3 can be suppressed.
[0042]
  next,5 to 7Refer to the present inventionFirst embodimentThe wall threading tool 1 of the wall through pipe according to the above will be described. As mentioned aboveReference exampleThe same reference numerals are given to the same components as those of the wall threading tool 1 of the wall through pipe according to the above, and the description thereof is omitted.
[0043]
  The installation hole 3 to which the wall threading tool 1 of the present embodiment is attached passes through the outer wall 2 along a direction orthogonal to the outer wall 2. The installation hole 3 is formed in a round shape. Moreover, the wall threading tool 1 of this embodiment is used in order to guide the hot water supplied from the water heater or the like from the upper side to the lower side as it goes from the outdoor O to the indoor I.
[0044]
  5 to 7As shown in FIG. 1, the wall threading tool 1 of the wall through pipe of the present embodiment is composed of only the first wall threading member 6. As for the 1st wall threading member 6 of this embodiment, the 1st cylinder part 8 is formed in the cylindrical shape. The first cylindrical portion 8 has an axis P along a direction orthogonal to the outer wall 2 when the wall threading tool 1 is attached to the installation hole 3.
[0045]
  When the wall threading tool 1 is attached to the installation hole 3, the width D along the vertical direction of the first tube portion 8 is formed to be about 2 to 3 times the outer diameter d of the sheath tube 5. Yes. A width D along the vertical direction of the first cylindrical portion 8 is formed sufficiently larger than the outer diameter d of the sheath tube 5. Further, the first wall passing member 6 is provided with a closing portion 12 at one end portion 8a exposed to the outdoor O side of the first cylindrical portion 8 when the wall threading tool 1 is attached to the installation hole 3.
[0046]
  The sheath tube guide 13 is formed so as to protrude from the closed portion 12 on the outdoor O side and obliquely upward. The sheath tube guide 13 protrudes from the end portion of the closing portion 12 positioned above the axis P. A smoothly curved surface 110 is formed at the joint between the sheath guide 13 and the closing portion 12 inside the first tube portion 8. The sheath tube guide 13 does not protrude from the inner surface 12 a of the closing portion 12 to the inside of the first tube portion 8.
[0047]
  A water-stop packing 14 is provided on the outer peripheral surface of the first cylinder portion 8 over the entire circumference.

  Further, the flange member 112 is fixed to the outer wall 2 with screws 115 or the like. Therefore, not only when the sheath pipe 5 and the pipe 4 are newly passed through the sheath pipe guide 13, but also when the aged pipe 4 is replaced with a new one, the pipe 4 and the sheath pipe 5 are connected to the sheath pipe guide 13. The operating force applied when passing through the inside can be distributed to the flange member 112 and supported by the outer wall 2.
[0066]
  For this reason, it can prevent that the wall threading tool 1 removes from the outer wall 2 etc. carelessly. Therefore, the installation state of the sheath pipe 5 to the outer wall 2 can be reliably maintained regardless of the insertion / extraction of the pipe 4.
[0067]
  Further, the flange mounting portion 111 includes a plurality of concave grooves 113 having different distances from the surface 12 b of the closing portion 12. For this reason, according to the thickness of the outer wall 2, the concave groove 113 with which the flange member 112 is engaged is arbitrarily selected, so that it can be easily attached to the installation holes 3 formed in the outer walls 2 having different thicknesses. it can.
[0068]
  In this example, the sheath tube 5 is inserted up to the stopper 13d that protrudes in the middle of the inner surface of the sheath tube guide 13, but the sheath tube 5 may be drawn out of the sheath tube guide 13. . In this case, the pipe 4 is also drawn out of the sheath pipe guide 13. In this way, it is possible to prevent water from entering the indoor I to a higher degree when water leaks from the connecting portion between the pipe 4 and the pipe 116.
[0069]
