Description

【0001】
【発明の属する技術分野】
本発明は通水部材が住宅などの建物において床または壁、天井を貫通する際の貫通構造に関する。
【0002】
【従来の技術】
従来の給水取出し構造例について図8に基づいて説明する。図8は、住宅の壁面に埋め込まれ、全自動洗濯機のホースに接続される通水部材である水栓1の分解斜視図であって、水栓1は正面に平面長方形状の開口を有するボックス2に収納されている。このボックス2は、壁ボード3に開設した長方形状の開口部5周縁部に固定枠6を用いて壁ボード3を挟持するように壁ボード3に取り付け固定される。そしてボックス2の開口は、固定枠6に設けた穴を通して、ねじ8にてボックス2に締付固定された耐火プレート7で覆われる。壁ボード3の裏側に敷設された可撓性を有する樹脂製の通水管4は、ボックス2底面に有する穴に下方より挿入しボックス2内にて水栓1と接続されている。
このような構成になっているため、施工後に通水管4と水栓1との接続部を点検する場合には、ねじ8を外し耐火プレート7を外すことで接続部を壁表側即ち室内より目視することができ、漏水有無を点検できる(例えば特許文献1参照。)。
【0003】
また別の従来例を図9に基づいて説明する。図9は壁面に施工した状態を示す部分断面図である。この例では、建築の柱(図示せず)にボックス12がねじ止め固定され、壁ボード3に開設された円形開口部11にボックス12上方前面の円筒状の開口凸部15が嵌め込まれている。このボックス12内に、ボックス12底面に取り付けられた鞘管13を通してボックス12内に通水管4を引き込み、ボックス12の開口凸部15の開口より通水管4の先端部を引き出してエルボ継手16と通水管4とを接続し、その後エルボ継手16をボックス12内に押し込む。その後ドーナツ状のロックリング21を開口凸部15内周にねじ込みエルボ継手16を固定し、更に壁ボード3の表側に化粧リング22を被せる。このような構成になっているため、通水管4とエルボ状の通水部16との接続部は円形開口部11より目視することができない奥に位置している(例えば特許文献2参照。)。

【発明が解決しようとする課題】
しかしながら前記構成では下記の課題を有している。
前記図8の構成では壁ボード3に長方形の開口部5を設けなくてはならない。この開口は建築現場にて行うことがほとんどである。壁ボード3が石膏ボード等のやわらかい材質であれば、壁ボード3に切断線を記した後カッターで開口を設けることが可能であるが、硬質のボードで有ればカッターを使用することができず、開口が非常に難しい作業となっていた。
【0006】
また前記図9の構成では、壁ボード3の開口部形状は円形であるため、ホールソー等の工具が使用でき、壁ボード材質が硬質材料であっても開口を設けることは難しくないが、通水管4以降の接続部の点検ができない。図9ではエルボ継手16と通水管4との接続部25の点検をしようとし、壁表側に接続してある水使用器具を外した後、ロックリング19、21、化粧リング22を外しても壁ボード3の表側より目視点検できない。接続部25を目視するには継手16をボックス12の開口凸部より引き出す必要があるが、前述のように通常、通水管4は一端をエルボ継手16に固定された後に他端をヘッダーに接続しているため、引き出すことができない。点検のためどうしてもエルボ継手16を引き出そうとすると通水管4とヘッダーとの接続を一度外す必要があるが、外した状態では通水できないため、エルボ継手16と通水管4との接続部25の問題有無の判定ができない。
【0007】
そこで上記の問題を解決するためにボード開口部の加工をしやすく、通水管との接続部の点検を行うことができる通水部材貫通構造を構成することを目的としている。
【0008】
【課題を解決するための手段】
上記問題を解決するため本発明の請求項1では、通水部材貫通構造において、隠蔽部に設置される通水管と、通水管と室内や屋外とを隔てる壁または床または天井を構成し円形開口部を有するボードと、ボードを円形開口部にて貫通するボード貫通部と通水管と接続する通水管接続部を有し屈曲部または曲がり部を備える通水部材を有する通水部材貫通構造において、通水管接続部は通水管接続状態で円形開口部より点検可能とした。
【0009】
これにより、通水部材を通水管に接続した状態にてボード表より通水管接続部の点検を行うことができる。
【0010】
さらに本発明の請求項2では、請求項1記載の通水部材貫通構造において、円形開口部の中心を、ボード貫通部中心と通水管接続部の間に設けた。
これにより円形開口部中心を、点検の必要な通水管接続部と、ボードの開口が必要なボード貫通部の間に位置させることができる。
【0011】
さらに本発明の請求項3では、請求項1乃至2記載の通水部材貫通構造において、円形開口部と同心円状のカバーを設けた。
これにより、最小面積のカバーにて開口部を塞ぐことができる。
【0012】
さらに本発明の請求項4では、請求項1乃至3記載の通水部材貫通構造において、ボード貫通部中心を軸としてカバーを360度回転させた際、どの位置においても室内または屋外から円形開口部を見えないようにした。
このようにすることにより、ボード貫通部中心に対してどの方向に隠蔽部通水管を配置しても、カバーを回転させる必要がない。
【0013】
さらに本発明の請求項5では、請求項3記載の通水部材貫通構造において、カバーは、ボードと、ボード貫通部に取付けられる取付ナットとで挟み込み固定されることとした。
【0014】
これにより、取付ナットを弛めるだけで、カバーを回転することができるので、接続している水使用器具(止水栓など)を取り外さずにボード裏の接続部を点検することができる。このため、点検のための時間も短くてよい。
【0015】
さらに本発明の請求項6では、請求項2乃至5記載の通水部材貫通構造において、通水部材を固定した後、ボードの円形開口部の中心を示すマークを有する開口中心位置指示部材を通水部材に固定し、開口中心位置指示部材に表示された中心位置にしたがって、ボードの開口を行う通水部材貫通部施工方法とした。
【0016】
このようにすることにより、示された開口中心位置を現場で測定してボード開口作業を行うことができるため、誤施工でボードを無駄にすることのなく、確実な施工をすることができる。
【0017】
【発明の実施の形態】
(実施の形態1)
本発明の実施の形態1において壁のボード隠蔽部に設置された通水管がボードを貫通する部位の構造について、図1、図2、図3に基づいて説明を行う。以下従来例と同じ役割の部位については同じ番号を用いて説明する。図2は貫通部施工完了状態の外観図、図1は図2よりカバー26を取り除いた状態の外観図、図3は貫通部施工完了状態の断面図である。
【0018】
図3において、壁ボード3の隠蔽部に配置された通水管4に、継手9を介して接続されたボード貫通部27を有するエルボ形状の通水部材28がボックス12に収められている。壁ボード3は、前記ボード貫通部27が通る円形開口部11を有する。また、壁ボード3の表側には固定枠6、とカバー26が配置されている。以下施工手順に沿って説明する。
【0019】
まず建築骨組の施工が終わった時点で、設置する部位の柱29にボックス12をねじ留め固定する。次に可撓性を有する通水管4の一端に継手9を接続する。この継手9は通水管を差し込むだけで接続できる、いわゆるワンタッチ接続の構造になっており接続時には2個のOリング30で継手9内面と通水管4の外面との間を水密に接続する。こうして接続した継手9をボックス12の下部より挿入し、ボックス12内にて通水部材28の一端31に接続する。この継手9の接続部は外周部に鍔部と2個のOリング32を有する円筒凸形状であり、対する通水部材28の一端31は外周部に鍔部を、内周部に平滑面を有する円筒形状をしており、接続時に2個のOリングが継手9の外面と通水部材28の内周部の平滑面との間を水密に接続する。この状態で継手9の鍔部と通水部材28の鍔部が当接されており、この2つの鍔部を取付板33のスリットにはめ込み、図1のようにねじ34にてボックス12に固定する。また、通水部材28は2箇所の穴付の凸部35を有しており、ねじ34をこの穴に通してボックス12に固定する。
【0020】
次に壁ボード3にホールソーを使用して円形開口部11を設ける。このとき、円形開口部11の中心38はボード貫通部27の中心39と通水管4と継手9との接続部40との間になるようにしている。このようにすることで接続部40の点検ができ、かつ壁ボード3の円形開口部11を小さくすることができる。この後、壁ボード3を図3のように柱29に固定する。これらの施工が終わった後、壁ボード3表側より円形の固定枠6を円形凸部41を壁ボード3の円形開口部11内面に嵌め合わせ、4つのねじ36にて壁ボード3にねじ込み固定する。この後爪部を有する円形のカバー26を固定枠6の穴37に合わせて嵌め込み固定する。このためカバー26は円形開口部11と同芯円となる。この状態で壁ボード表側より見た外観図が図2となる。ボード貫通部27は内周部に雌ねじ部を有しており、この後に水栓等の通水器具をねじ込むことにより、通水器具に水を供給することができる。またカバー26を取り外すことにより、通水管4と継手9との最初の接続部40以降の接続部全ての目視点検を行うことができる。
【0021】
本発明の実施の形態1では壁ボード3の開口形状を円形としているため、ホールソー等の円形開口用工具を使用でき、開口作業が非常に簡単になる。こうすることにより、硬質のボード、例えばタイル、石材、軽量コンクリート板等でも問題なく開口作業をすることができる。また壁ボード3の円形開口部11の中心38を、ボード貫通部27の中心39と、通水管4と継手9との接続部40との間に設けている。継手9は通水管4と直接接続されていることから、通水管4からボード貫通部27までの接水部材(本発明の実施の形態1では通水部材28と継手9)の全ての接続部を壁ボード3の表側より円形開口部11を通して目視点検をすることができ、万一漏水した場合にも建築躯体である壁ボード3を破壊せずにすむ。また前述のようにカバー26と壁ボード3の円形開口部11を同芯の円という相似形状とした。このため円形のカバー26は最小の面積で壁ボード3の円形開口部11を塞ぐことができるため、壁ボード3の表側に設置されるカバー26が他の部材(例えば壁下部の幅木等)に干渉して施工できないという問題が起こりにくくなる。
【0022】
(実施の形態2)
本発明の実施の形態2において壁のボード隠蔽部に設置された通水管がボードを貫通する部位の別の構造について、図4、図5、図6に基づいて説明を行う。図4、図5、図6は何れも壁ボード3にボード貫通部27を有する通水部材28を施工した、施工完了状態の壁ボード3の表側よりみた外観図である。但し説明の都合上、各図の囲み線46内ではカバー内部の外観図としている。
【0023】
図4において壁ボード3の裏側隠蔽部の構造は本発明の実施の形態1と同じであるが円形開口部11に対してカバー42が大きくなっている。このカバー42はボード貫通部27が通る穴を中心とした円形状であり、壁ボード3にねじ36にて直接ねじ留めされている。ここで2点鎖線の円43は、ボード貫通部27の中心から円形開口部11外周上での最遠点44を、ボード貫通部27を中心として360度回転させたときの軌跡である。カバー42の外周円がこの円43より大きくなっている。即ちボード貫通部27の中心から、最遠点44までの距離(円43の半径)をL1とし、カバー42の半径をR1とすると、全周にわたってL1<R1となっている。こうすることによりカバー42は通水管4の配管方向による影響を受けない。
【0024】
配管方向は建築現場によって種々の制約を受ける。例えば床下空間の高さが低い集合住宅で、壁下部の床付近に通水部材28のボード貫通部27を設ける必要のある場合では、床下から通水管を配置する際に真下から配管をすることができない。こうしようとすると通水管4の最小曲げ半径を確保することができない。このため斜め下方より通水管を配置する必要がある。また窓を有する壁において窓の直下に通水部材28のボード貫通部27を設ける必要のある場合には、同じ理由により真上から配管できず、斜め上方より配管を行う必要がある。このような場合も図4のような構成をとれば問題は発生しない。図5は通水管4が右上より配管されている例である。これは壁ボード3裏側の部材が図4の状態と比較して反時計廻りに約135度回転した状態であるがカバー42は回転の必要がなく、図4、図5のように使用者に説明するための「給水接続口」という文字も回転することなく視認させることができる。
【0025】
また図6のように、カバー45の外形が円でなくても良い。このカバー45は略正方形であるが、前述の図4のカバー42と同じく2点鎖線で示す円43よりカバー45が大きくなっている。即ちボード貫通部27の中心から最遠点44までの距離(円43の半径)をL1とし、カバー45の一片の距離の半分をL2とすると、全周にわたりL1<L2である。このため通水管4の配管方向が変化しても、円43の範囲内でしか円形開口部の位置が変わらないようにできるので、カバー45の取付け方法を変更する必要が無い。
【0026】
なお本発明の実施の形態2ではカバー45が略正方形の場合であるが、本発明はこれに限られるものではなく、三角形や他の多角形等どのような形状でも良い。
【0027】
(実施の形態3)
本発明の実施の形態3において壁のボード隠蔽部に設置された通水管がボードを貫通する部位の別の構造について、図7に基づいて説明を行う。
【0028】
図7は壁ボード3にボード貫通部27を有する通水部材28を施工した、施工完了状態の壁ボード3の表側よりみた外観図である。但し説明の都合上、囲み線46内ではカバー内部の外観図としている。まず建築骨組の施工が終了した後、通水部材28を設置する位置に当木47を設け、近接している柱に当木47の両端を固定する。この後、木製の固定具48を2本のねじ49にて当木47に固定する。
【0029】
次に通水部材28の凸部35の穴を使用してねじ34にて固定具48に締付固定する。次に本発明の実施の形態1と同じ構造の継手9に通水管4を接続し、さらにこの継手9を通水部材28に挿入し、取付板33をねじ34にて固定具48に固定する。この後、壁ボード3の円形開口部50(この円はボード貫通部27を中心として通水管4と継手9との接続部40より大きくなっている。)をホールソーにて設けた後、壁ボード3を建築躯体の柱(図示せず)に固定する。最後にカバー51をねじ36にて壁ボード3に固定する。
【0030】
本発明の実施の形態3では壁ボード3の円形開口部50が、ボード貫通部27および通水管4と継手9との接続部40を含むためカバー51を壁ボード3から取り外すことにより目視点検ができる。また円形開口部50(半径をR2とする。)とカバー51(半径をR3とする。)が同芯の円形状という相似形状をしているため、ボードの開口面積に対してカバー51の面積が最小で済む。またR2<R3としているため、ボード貫通部27を中心としてカバー51を360度回転させた際、どの位置においても壁表(室内側)より円形開口部50を目視することができない。このため、ボード貫通部27の中心に対してどの方向から通水管4が配管された場合でもカバー51の壁ボード3への取付方向に影響を与えない。
【0031】
(実施の形態4)
本発明の実施の形態4において壁のボード隠蔽部に設置された通水管がボードを貫通する部位の構造について、図10から図18に基づいて説明を行う。
図10は貫通部施工完了状態の外観図、図11は貫通部施工完了状態の断面図、図12から図17は施工途中を示す斜視図、図18は養生キャップを示す図である。
【0032】
図11において、壁ボード66の隠蔽部に配置された通水管65に継手64を介して接続された、ボード貫通部69を有するエルボ形状の通水部材63が、当木67に固定されている。壁ボード66は、ボード貫通部69が通る円形開口部71を有する。また、壁ボード66の表側にはパッキン70とカバー61が配置されている。ボード貫通部69の外径にはねじ加工が施されており、取付ナット62と螺合してカバー61を固定している。
【0033】
以下施工手順に沿って説明する。
図12に示すように、まず建築骨組の施工が終わった時点で、設置する部位の当木67に、ボード貫通部69を有するエルボ形状の通水部材63をねじ留め固定し、通水管65を接続した継手64を通水部材63に挿入し、金属製のクイックファスナー10にて接続固定する。このとき、通水管65は可撓性を有するので継手64を容易に固定できる。
【0034】
次に、図13に示すように、ボード貫通部69の外径ねじ部に養生キャップ68をはめ込む。この養生キャップ68は、壁ボード66にホールソーを使用して円形開口部71をあける際、開口中心位置指示する役目を果たすものである。すなわち、この開口中心位置指示部材である養生キャップ68の位置を現場で測定し、壁ボード66にホールソーを使用して円形開口部71を設けるのである。なお、養生キャップには円形開口部71の中心位置を示すマークが表示されている。図18にその一例を示す。
【0035】
このとき、円形開口部71の中心38はボード貫通部69の中心39と、通水管65と継手64との接続部40との間になるようにしている。このようにすることで接続部40の点検ができ、かつ壁ボード66の円形開口部71を小さくすることができる。この後、壁ボード66を柱29に固定する。
【0036】
これらの施工が終わった後、図14に示すように、壁ボード66の表側より養生キャップ68の切り欠き73を使用して、開口中心位置指示部材である養生キャップ68を取り外す。切り欠き73は、図示した形状に限定されるものではなく、貫通した穴でも良い。
【0037】
続いて、図15及び図16に示すように、ボード貫通部69にカバー61を挿入し取付ナット62をボード貫通部材69の外径ねじに締め込んで固定する。
【0038】
ボード貫通部69は内周部に雌ねじ部を有しており、この後に水栓等の通水器具をねじ込むことにより、通水器具に水を供給することができる。
また取付ナット62を緩めるだけで、カバー61を回転することができ、接続している水使用器具(止水栓72など)を取り外さずにボード裏の接続部を点検することができる。これは、カバー61の回転中心である中心39と開口部中心である中心38とが同軸ではなく偏心しているためである。図17に示すように、カバー61は中心39を中心に回転し円形開口部71より点検することができる。
【0039】
このような施工手順をとることができるので、次のような利点がある。
通水部材63のボード貫通部中心位置39と異なる位置38を中心として、ボードの円形開口部71を設ける必要があるが、通水管65の配管方向は、建築条件(窓の位置など)により、上下左右斜め等、あらゆる方向の場合があり、現場で配管角度を計算して、正確にボード開口中心を求めるのはわずらわしく、難しい。この方法では、養生キャップ68により示された開口中心位置を現場で測定してボード開口作業を行うことができるため、誤施工でボードを無駄にすることのなく、確実な施工をすることができる。
【0040】
また、開口中心位置指示部材である養生キャップ68の外形が、ボード開口部71の最小必要サイズになっているため、万一施工者の作業ミスで、開口サイズが不足した場合に、開口したボードを建築躯体に固定する際に、ボードと開口中心位置指示部材である養生キャップ68が干渉し、施工者にミスを気付かせることができる。
【0041】
これに気付かなかった場合は、施工完了後の点検の際にミスに気付くことになり、それからでは、ボードのみでなく仕上げ材(化粧ボードや壁紙など)を取り外しての作業のやり直しとなり、やり直し費用が高くなるばかりでなく、建築工期も大幅に伸びることになる。
【0042】
以上説明したように本発明の請求項1では、通水部材貫通構造において、隠蔽部に設置される通水管と、前記通水管と室内や屋外とを隔てる壁または床または天井を構成し円形開口部を有するボードと、前記ボードを前記円形開口部にて貫通するボード貫通部と前記通水管と接続する通水管接続部を有し屈曲部または曲がり部を備える通水部材を有する通水部材貫通構造において、前記通水管接続部は前記通水管接続状態で前記円形開口部より点検可能としたので、通水部材を通水管に接続した状態にてボード表より通水管接続部の点検を行うことができ、漏水等必要な場合にのみ配管の交換等のメンテナンス作業を行うことができ、メンテナンスコストを低減させることができる。
【0043】
さらに本発明の請求項2では、請求項1記載の通水部材貫通構造において、前記円形開口部の中心を、ボード貫通部中心と前記通水管接続部の間に設けたので、円形開口部中心を、点検の必要な通水管接続部と、ボードの開口が必要なボード貫通部の間に位置させることができるので、ボードへの開口が小さくてよくボードの強度や外観に対する影響を小さくすることができる。
【0044】
さらに本発明の請求項3では、請求項1乃至2記載の通水部材貫通構造において、前記円形開口部と同心円状のカバーを設けたので、カバーが最小面積にて開口部を塞ぐことができ、外観への影響を小さくすることができ、またカバー製作コストを低減させることができる。
【0045】
さらに本発明の請求項4では、請求項1乃至3記載の通水部材貫通構造において、前記ボード貫通部中心を軸として前記カバーを360度回転させた際、どの位置においても室内または屋外から前記円形開口部を見えないようにしたので、隠蔽部通水管の配管方向により、カバーを回転させる必要がなく、カバー形状や表面の表示への制約をなくすことができる。
【0046】
さらに本発明の請求項5では、請求項3記載の通水部材貫通構造において、カバーは、ボードと、ボード貫通部に取付けられる取付ナットとで挟み込み固定されることとした。
これにより、取付ナットを弛めるだけで、カバーを回転することができるので、接続している水使用器具(止水栓など)を取り外さずにボード裏の接続部を点検することができる。このため、点検のための時間も短くてよい。
【0047】
さらに本発明の請求項6では、請求項2乃至5記載の通水部材貫通構造において、通水部材を固定した後、ボードの円形開口部の中心を示すマークを有する開口中心位置指示部材を通水部材に固定し、開口中心位置指示部材に表示された中心位置にしたがって、ボードの開口を行う通水部材貫通部施工方法とした。
【0048】
このようにすることにより、示された開口中心位置を現場で測定してボード開口作業を行うことができるため、誤施工でボードを無駄にすることのなく、確実な施工をすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a penetration structure when a water-permeable member penetrates a floor, a wall, or a ceiling in a building such as a house.
[0002]
[Prior art]
An example of a conventional water supply take-out structure will be described with reference to FIG. FIG. 8 is an exploded perspective view of a faucet 1 which is embedded in a wall of a house and is a water-passing member connected to a hose of a fully automatic washing machine, and the faucet 1 has a flat rectangular opening on the front. It is stored in Box 2. The box 2 is attached to and fixed to the wall board 3 so as to sandwich the wall board 3 by using a fixing frame 6 around a rectangular opening 5 formed in the wall board 3. The opening of the box 2 is covered with a fireproof plate 7 which is fastened and fixed to the box 2 with screws 8 through holes provided in the fixing frame 6. A flexible resin water pipe 4 laid on the back side of the wall board 3 is inserted from below into a hole provided on the bottom surface of the box 2 and connected to the faucet 1 in the box 2.
With such a configuration, when inspecting the connection between the water pipe 4 and the faucet 1 after the installation, the screw 8 is removed and the refractory plate 7 is removed to visually check the connection from the front side of the wall, that is, from the room. And the presence or absence of water leakage can be checked (for example, see Patent Document 1).
[0003]
Another conventional example will be described with reference to FIG. FIG. 9 is a partial cross-sectional view showing a state in which it is installed on a wall surface. In this example, a box 12 is screwed and fixed to a pillar (not shown) of a building, and a cylindrical opening protrusion 15 on the front upper surface of the box 12 is fitted into a circular opening 11 opened in the wall board 3. . The water pipe 4 is drawn into the box 12 through the sheath tube 13 attached to the bottom surface of the box 12, and the leading end of the water pipe 4 is pulled out from the opening of the opening projection 15 of the box 12, and the elbow joint 16 is formed. Then, the elbow joint 16 is pushed into the box 12. Thereafter, a donut-shaped lock ring 21 is screwed into the inner periphery of the opening projection 15 to fix the elbow joint 16, and a decorative ring 22 is put on the front side of the wall board 3.

[0005]
[Problems to be solved by the invention]
However, the above configuration has the following problems.
In the configuration shown in FIG. 8, a rectangular opening 5 must be provided in the wall board 3. This opening is usually made at a building site. If the wall board 3 is a soft material such as gypsum board, it is possible to provide an opening with a cutter after marking a cutting line on the wall board 3, but if it is a hard board, a cutter can be used. Opening was a very difficult task.
[0006]
In the configuration shown in FIG. 9, the opening of the wall board 3 is circular, so that a tool such as a hole saw can be used. Even if the wall board is made of a hard material, it is not difficult to provide an opening. Inspection of connections after 4 is not possible. In FIG. 9, an attempt is made to inspect the connecting portion 25 between the elbow joint 16 and the water pipe 4, and after removing the water-using equipment connected to the wall surface side, the lock rings 19, 21 and the decorative ring 22 are removed. Visual inspection is not possible from the front side of the board 3. It is necessary to pull out the joint 16 from the convex portion of the opening of the box 12 in order to visually check the connecting portion 25. However, as described above, the water pipe 4 usually has one end fixed to the elbow joint 16 and the other end connected to the header. And cannot be withdrawn. If an attempt to get a really elbow joint 16 for maintenance is necessary to remove the connection to the water pipe 4 and the headers once, it can not be water passing in the state where the removed, problems of the connecting portion 25 of the elbow joint 16 and water pipe 4 The presence or absence cannot be determined.
[0007]
Therefore, in order to solve the above-mentioned problem, an object of the present invention is to provide a water-permeable member penetrating structure capable of easily processing a board opening and inspecting a connection part with a water pipe.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the first aspect of the present invention, in the water-permeable member penetrating structure, a circular opening formed by a water pipe installed in the concealing section and a wall or a floor or a ceiling separating the water pipe from the room or the outside. Board having a portion, a water-passing member penetrating structure having a water-passing member having a bent portion or a bent portion and having a water-passing pipe connecting portion to connect with the water-passing portion and a board penetrating portion penetrating the board at the circular opening, The connection part of the water pipe can be inspected from the circular opening when the water pipe is connected.
[0009]
Thus, the water pipe connection portion can be inspected from the board table in a state where the water flow member is connected to the water pipe.
[0010]
According to a second aspect of the present invention, in the water-permeable member penetrating structure according to the first aspect, the center of the circular opening is provided between the center of the board penetrating part and the water-flow pipe connecting part.
This allows the center of the circular opening to be located between the water pipe connection that requires inspection and the board penetration that requires the board opening.
[0011]
According to a third aspect of the present invention, in the water-permeable member penetrating structure according to the first or second aspect, a cover concentric with the circular opening is provided.
Thus, the opening can be closed by the cover having the minimum area.
[0012]
According to a fourth aspect of the present invention, in the water-permeable member penetrating structure according to any one of the first to third aspects, when the cover is rotated by 360 degrees around the center of the board penetrating portion, the circular opening is formed from indoor or outdoor at any position. Was made invisible.
By doing so, it is not necessary to rotate the cover regardless of the direction in which the concealing section water pipe is disposed with respect to the center of the board penetration section.
[0013]
According to a fifth aspect of the present invention, in the water-permeable member penetration structure according to the third aspect, the cover is sandwiched and fixed between the board and a mounting nut attached to the board penetration portion.
[0014]
Thus, the cover can be rotated only by loosening the mounting nut, so that the connection portion on the back of the board can be inspected without removing the connected water-using tool (water stopcock or the like). Therefore, the time for inspection may be short.
[0015]
According to a sixth aspect of the present invention, in the water-permeable member penetrating structure according to any one of the second to fifth aspects, after the water-permeable member is fixed, the opening center position indicating member having a mark indicating the center of the circular opening of the board is passed through. A water-permeable member penetrating portion was fixed to the water member and the board was opened according to the center position indicated on the opening center position indicating member.
[0016]
By doing so, the board opening operation can be performed by measuring the indicated center position of the opening at the site, so that the board can be reliably installed without wasting the board due to erroneous installation.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
(Embodiment 1)
In Embodiment 1 of the present invention, a structure of a portion where a water pipe installed in a board concealing portion of a wall penetrates a board will be described with reference to FIGS. 1, 2, and 3. FIG. Hereinafter, portions having the same role as in the conventional example will be described using the same numbers. 2 is an external view of the completed state of the penetration portion, FIG. 1 is an external view of the state in which the cover 26 is removed from FIG. 2, and FIG. 3 is a cross-sectional view of the completed state of the penetration portion.
[0018]
In FIG. 3, an elbow-shaped water passage member 28 having a board penetration portion 27 connected via a joint 9 is housed in the box 12 in the water passage pipe 4 arranged in the concealing portion of the wall board 3. The wall board 3 has a circular opening 11 through which the board penetration 27 passes. The fixed frame 6 and the cover 26 are arranged on the front side of the wall board 3. Hereinafter, the construction procedure will be described.
[0019]
First, when the construction of the architectural frame is completed, the box 12 is screwed and fixed to the pillar 29 of the installation site. Next, the joint 9 is connected to one end of the flexible water pipe 4. The joint 9 has a so-called one-touch connection structure that can be connected simply by inserting a water pipe. At the time of connection, two O-rings 30 connect the inner surface of the joint 9 and the outer surface of the water pipe 4 in a watertight manner. The joint 9 thus connected is inserted from the lower part of the box 12 and connected to one end 31 of the water-passing member 28 in the box 12. The connecting portion of the joint 9 has a cylindrical convex shape having a flange portion and two O-rings 32 on the outer peripheral portion. One end 31 of the water-passing member 28 has a flange portion on the outer peripheral portion and a smooth surface on the inner peripheral portion. The two O-rings watertightly connect the outer surface of the joint 9 and the smooth surface of the inner peripheral portion of the water-passing member 28 at the time of connection. In this state, the flange of the joint 9 and the flange of the water-passing member 28 are in contact with each other, and these two flanges are fitted into the slits of the mounting plate 33 and fixed to the box 12 with screws 34 as shown in FIG. I do. The water-passing member 28 has two convex portions 35 with holes, and the screws 34 are passed through these holes and fixed to the box 12.
[0020]
Next, a circular opening 11 is provided on the wall board 3 using a hole saw. At this time, the center 38 of the circular opening 11 is set between the center 39 of the board penetration portion 27 and the connection portion 40 between the water pipe 4 and the joint 9. By doing so, the connection portion 40 can be inspected, and the circular opening 11 of the wall board 3 can be reduced. Thereafter, the wall board 3 is fixed to the pillar 29 as shown in FIG. After these constructions are completed, the circular fixing frame 6 is fitted to the inner surface of the circular opening 11 of the wall board 3 with the circular fixing frame 6 from the front side of the wall board 3, and is screwed and fixed to the wall board 3 with four screws 36. . The circular cover 26 having the rear claw portion is fitted and fixed in accordance with the hole 37 of the fixed frame 6. Therefore, the cover 26 is concentric with the circular opening 11. FIG. 2 is an external view in this state viewed from the front side of the wall board. The board penetration part 27 has a female screw part in the inner peripheral part, and after that, by screwing a water flow device such as a faucet, water can be supplied to the water flow device. In addition, by removing the cover 26, it is possible to perform a visual inspection of all of the connection portions after the first connection portion 40 between the water pipe 4 and the joint 9.
[0021]
In the first embodiment of the present invention, since the opening shape of the wall board 3 is circular, a circular opening tool such as a hole saw can be used, and the opening operation becomes very simple. In this way, the opening work can be performed on a hard board, for example, a tile, a stone, a lightweight concrete board or the like without any problem. The center 38 of the circular opening 11 of the wall board 3 is provided between the center 39 of the board penetration part 27 and the connection part 40 between the water pipe 4 and the joint 9. Since the joint 9 is directly connected to the water pipe 4, all the connecting parts of the water contact members (the water member 28 and the joint 9 in the first embodiment of the present invention) from the water pipe 4 to the board penetrating portion 27. Can be visually inspected from the front side of the wall board 3 through the circular opening 11, and even if water leaks, the wall board 3 which is the building frame does not need to be destroyed. Further, as described above, the circular opening 11 of the cover 26 and the wall board 3 has a similar shape of a concentric circle. For this reason, since the circular cover 26 can cover the circular opening 11 of the wall board 3 with a minimum area, the cover 26 installed on the front side of the wall board 3 is made of another member (for example, a baseboard at the bottom of the wall). The problem that the construction cannot be performed due to interference with the work hardly occurs.
[0022]
(Embodiment 2)
Another structure of a portion where a water pipe installed in a board concealing portion of a wall penetrates a board in Embodiment 2 of the present invention will be described with reference to FIGS. 4, 5, and 6. FIG. 4, 5, and 6 are all external views of the wall board 3 in which the water-passing member 28 having the board penetrating portion 27 has been installed on the wall board 3, when viewed from the front side of the completed wall board 3. However, for convenience of explanation, the enclosed line 46 in each figure is an external view of the inside of the cover.
[0023]
In FIG. 4, the structure of the back side concealing portion of the wall board 3 is the same as that of the first embodiment of the present invention, but the cover 42 is larger than the circular opening 11. The cover 42 has a circular shape centered on a hole through which the board penetration portion 27 passes, and is directly screwed to the wall board 3 with screws 36. Here, the two-dot chain line circle 43 is a trajectory when the farthest point 44 on the outer periphery of the circular opening 11 from the center of the board penetration part 27 is rotated by 360 degrees about the board penetration part 27. The outer peripheral circle of the cover 42 is larger than the circle 43. That is, if the distance (radius of the circle 43) from the center of the board penetration portion 27 to the farthest point 44 is L1 and the radius of the cover 42 is R1, then L1 <R1 over the entire circumference. By doing so, the cover 42 is not affected by the piping direction of the water pipe 4.
[0024]
The piping direction is subject to various restrictions depending on the construction site. For example, in a multi-family house where the height of the underfloor space is low, when it is necessary to provide the board penetration portion 27 of the water-permeable member 28 near the floor below the wall, when arranging the water pipe from under the floor, piping should be performed from directly below. Can not. In this case, the minimum bending radius of the water pipe 4 cannot be secured. For this reason, it is necessary to arrange a water pipe from diagonally below. When it is necessary to provide the board penetration portion 27 of the water-passing member 28 directly below the window in the wall having the window, it is not possible to perform piping from directly above for the same reason, and it is necessary to perform piping from obliquely above. Even in such a case, no problem occurs if the configuration shown in FIG. 4 is employed. FIG. 5 shows an example in which the water pipe 4 is provided from the upper right. This is a state in which the member on the back side of the wall board 3 has been rotated about 135 degrees counterclockwise as compared with the state of FIG. 4, but the cover 42 does not need to be rotated, and as shown in FIGS. The character "water supply connection port" for explanation can also be visually recognized without rotating.
[0025]
Further, as shown in FIG. 6, the outer shape of the cover 45 may not be a circle. Although the cover 45 is substantially square, the cover 45 is larger than the circle 43 shown by a two-dot chain line similarly to the cover 42 of FIG. That is, assuming that the distance (radius of the circle 43) from the center of the board penetration portion 27 to the farthest point 44 is L1, and half the distance of one piece of the cover 45 is L2, L1 <L2 over the entire circumference. For this reason, even if the pipe direction of the water pipe 4 changes, the position of the circular opening can be changed only within the range of the circle 43, so that there is no need to change the method of attaching the cover 45.
[0026]
In the second embodiment of the present invention, the cover 45 has a substantially square shape. However, the present invention is not limited to this, and may have any shape such as a triangle or another polygon.
[0027]
(Embodiment 3)
Another structure of a part where a water pipe installed in a board concealing portion of a wall penetrates a board in Embodiment 3 of the present invention will be described with reference to FIG.
[0028]
FIG. 7 is an external view of the wall board 3 in which the water-passing member 28 having the board penetrating portion 27 is installed on the wall board 3 in a completed state, as viewed from the front side. However, for the sake of explanation, the inside of the cover is an external view inside the enclosing line 46. First, after the construction of the building frame is completed, the wood 47 is provided at the position where the water-permeable member 28 is installed, and both ends of the wood 47 are fixed to the adjacent columns. Thereafter, the wooden fixture 48 is fixed to the wood 47 with two screws 49.
[0029]
Next, using the hole of the convex portion 35 of the water-passing member 28, it is tightened and fixed to the fixture 48 with the screw 34. Next, the water pipe 4 is connected to the joint 9 having the same structure as in the first embodiment of the present invention, and the joint 9 is inserted into the water-permeable member 28, and the mounting plate 33 is fixed to the fixture 48 with the screw 34. . After that, a circular opening 50 of the wall board 3 (this circle is larger than the connection part 40 between the water pipe 4 and the joint 9 around the board penetration part 27) is provided by a hole saw, and then the wall board is provided. 3 is fixed to a pillar (not shown) of the building frame. Finally, the cover 51 is fixed to the wall board 3 with the screws 36.
[0030]
In the third embodiment of the present invention, since the circular opening 50 of the wall board 3 includes the board penetrating portion 27 and the connecting portion 40 between the water pipe 4 and the joint 9, the cover 51 is removed from the wall board 3 for visual inspection. it can. Further, since the circular opening 50 (radius is R2) and the cover 51 (radius is R3) have similar shapes of concentric circles, the area of the cover 51 is larger than the opening area of the board. Is minimal. Further, since R2 <R3, when the cover 51 is rotated 360 degrees around the board penetration portion 27, the circular opening 50 cannot be seen from the wall surface (inside the room) at any position. For this reason, even if the water pipe 4 is laid from any direction with respect to the center of the board penetration portion 27, the direction in which the cover 51 is attached to the wall board 3 is not affected.
[0031]
(Embodiment 4)
In Embodiment 4 of the present invention, a structure of a portion where a water pipe installed in a board concealing portion of a wall penetrates a board will be described with reference to FIGS.
FIG. 10 is an external view of the completed state of the penetrating portion, FIG. 11 is a cross-sectional view of the completed state of the penetrating portion, FIGS. 12 to 17 are perspective views showing the middle of the construction, and FIG. 18 is a diagram showing the curing cap.
[0032]
In FIG. 11, an elbow-shaped water-passing member 63 having a board penetration portion 69 connected to a water-passage pipe 65 arranged in a concealing portion of a wall board 66 via a joint 64 is fixed to the wood 67. . The wall board 66 has a circular opening 71 through which the board penetration 69 passes. A packing 70 and a cover 61 are arranged on the front side of the wall board 66. The outer diameter of the board penetration portion 69 is threaded, and the cover 61 is fixed by screwing with the mounting nut 62.
[0033]
Hereinafter, the construction procedure will be described.
As shown in FIG. 12, first, when the construction of the building frame is completed, an elbow-shaped water-passing member 63 having a board penetration portion 69 is screwed and fixed to the timber 67 at the installation site, and the water-passage pipe 65 is connected. The connected joint 64 is inserted into the water-permeable member 63, and connected and fixed by the metal quick fastener 10. At this time, since the water pipe 65 has flexibility, the joint 64 can be easily fixed.
[0034]
Next, as shown in FIG. 13, the curing cap 68 is fitted into the external thread portion of the board penetration portion 69. The curing cap 68 serves to indicate the center position of the opening when the circular opening 71 is opened in the wall board 66 using a hole saw. That is, the position of the curing cap 68 as the opening center position indicating member is measured on site, and the circular opening 71 is provided on the wall board 66 using a hole saw. A mark indicating the center position of the circular opening 71 is displayed on the curing cap. FIG. 18 shows an example.
[0035]
At this time, the center 38 of the circular opening 71 is set between the center 39 of the board penetration part 69 and the connection part 40 between the water pipe 65 and the joint 64. By doing so, the connection portion 40 can be inspected, and the circular opening 71 of the wall board 66 can be reduced. Thereafter, the wall board 66 is fixed to the pillar 29.
[0036]
After these constructions are completed, as shown in FIG. 14, the curing cap 68, which is the opening center position indicating member, is removed from the front side of the wall board 66 using the notch 73 of the curing cap 68. The notch 73 is not limited to the illustrated shape, and may be a through hole.
[0037]
Subsequently, as shown in FIGS. 15 and 16, the cover 61 is inserted into the board penetrating portion 69, and the mounting nut 62 is tightened and fixed to the outer diameter screw of the board penetrating member 69.
[0038]
The board penetration part 69 has a female screw part in the inner peripheral part, and after that, water can be supplied to the water passage device by screwing a water passage device such as a faucet.
Further, the cover 61 can be rotated simply by loosening the mounting nut 62, and the connection portion on the back of the board can be inspected without removing the connected water-using device (such as the water stopcock 72). This is because the center 39 which is the center of rotation of the cover 61 and the center 38 which is the center of the opening are not coaxial but eccentric. As shown in FIG. 17, the cover 61 rotates about the center 39 and can be inspected from the circular opening 71.
[0039]
Since such a construction procedure can be taken, there are the following advantages.
It is necessary to provide a circular opening 71 of the board around a position 38 different from the center position 39 of the board penetrating portion of the water passage member 63, but the piping direction of the water passage 65 depends on construction conditions (such as the position of windows). There may be any direction such as up, down, left, right, diagonal, etc. It is troublesome and difficult to calculate the pipe angle on site and to accurately determine the center of the board opening. According to this method, since the opening center position indicated by the curing cap 68 can be measured on site to perform the board opening operation, the board can be reliably installed without wasting the board due to erroneous installation. .
[0040]
In addition, since the outer shape of the curing cap 68, which is the opening center position indicating member, is the minimum required size of the board opening 71, if the opening size is insufficient due to a work error of the builder, the opened board is opened. When fixing to the building frame, the board and the curing cap 68 as the opening center position indicating member interfere with each other, so that the construction worker can notice an error.
[0041]
If you do not notice this, you will notice a mistake during the inspection after the completion of construction, and then you will have to remove the finishing materials (such as decorative board and wallpaper) as well as the board and start over, and the cost of starting over Not only will the cost increase, but the construction period will also increase significantly.
[0042]
As described above, according to the first aspect of the present invention, in the water-permeable member penetrating structure, the water-permeable pipe installed in the concealing portion and the wall, floor, or ceiling that separates the water-permeable pipe from the room or the outside are formed in the circular opening. A water-passing member having a board-passing portion penetrating the board at the circular opening, and a water-passing member having a bent portion or a bent portion and having a water-passage connecting portion connecting to the water-passing portion. In the structure, since the water pipe connection part can be inspected from the circular opening in the water pipe connection state, the water pipe connection part is inspected from the board table in a state where the water transmission member is connected to the water pipe. Therefore, maintenance work such as replacement of pipes can be performed only when water leakage or the like is necessary, and maintenance costs can be reduced.
[0043]
Furthermore, in the second aspect of the present invention, in the water-permeable member penetrating structure according to the first aspect, the center of the circular opening is provided between the center of the board penetrating part and the water pipe connection part. Can be located between the water pipe connection that requires inspection and the board penetration that requires the board opening, so the opening to the board is small and the effect on the strength and appearance of the board is reduced. Can be.
[0044]
Further, in the third aspect of the present invention, in the water-permeable member penetrating structure according to the first or second aspect, since the cover concentric with the circular opening is provided, the cover can close the opening with a minimum area. In addition, the influence on the appearance can be reduced, and the cost of manufacturing the cover can be reduced.
[0045]
Further, according to claim 4 of the present invention, in the water-permeable member penetration structure according to claims 1 to 3, when the cover is rotated 360 degrees around the center of the board penetration portion as an axis, at any position from indoor or outdoor. Since the circular opening is made invisible, there is no need to rotate the cover depending on the piping direction of the concealing part water pipe, and it is possible to eliminate restrictions on the cover shape and surface display.
[0046]
According to a fifth aspect of the present invention, in the water-permeable member penetration structure according to the third aspect, the cover is sandwiched and fixed between the board and a mounting nut attached to the board penetration portion.
Thus, the cover can be rotated only by loosening the mounting nut, so that the connection portion on the back of the board can be inspected without removing the connected water-using tool (water stopcock or the like). Therefore, the time for inspection may be short.
[0047]
According to a sixth aspect of the present invention, in the water-permeable member penetrating structure according to any one of the second to fifth aspects, after the water-permeable member is fixed, the opening center position indicating member having a mark indicating the center of the circular opening of the board is passed through. A water-permeable member penetrating portion was fixed to the water member and the board was opened according to the center position indicated on the opening center position indicating member.
[0048]
By doing so, the board opening operation can be performed by measuring the indicated center position of the opening at the site, so that the board can be reliably installed without wasting the board due to erroneous installation.
