【０００１】
【発明の属する技術分野】
本発明は、床面部に設けられた穴部を挿通して屋外側から屋内に延びる配管を床面部上で起立させた状態で支持する配管立上げ構造に関する。
【０００２】
【従来の技術】
従来から、浴室、トイレ、洗面所、台所等の家屋内の各場所には、水や湯を取り出すための蛇口や取水口が設けられている。この蛇口等は、屋外に設けられた水供給用の水道管から分離して屋内に水を供給するための配管に接続されており、この配管は床面部に設けられた穴部を通過して所定の場所まで延ばされている。このような配管としては、施工性や価格の面から一般に可撓性を有し安価な樹脂製の管が使用されている。
【０００３】
そして、配管における床面部の穴部に位置する部分は、穴部の周縁部との間に防水構造が設けられて水漏れが生じないようにされた状態で、床面部上に起立した姿勢で固定されている。このような配管の起立姿勢での固定と床面部に設けた穴部の水漏れ防止ができる配管立上げ構造として、ゴムパッキンとホースバンドとを用いたものがある（例えば、特許文献１参照）。
【０００４】
この配管立上げ構造では、床面部に設けた穴部に、配管挿通用の挿通穴を有するゴムパッキンを取り付け、配管の先端部を床面部の穴部とゴムパッキンの挿通穴とに通して床面部の上方に突出させている。そして、配管の外周部にゴムパッキンの挿通穴の近傍部分を巻き付け、その部分をホースバンドで締め付けることによって、配管を起立させた状態でゴムパッキンに固定している。

【発明が解決しようとする課題】
しかしながら、前述した従来の配管立上げ構造では、ホースバンドを取り付ける施工によって水漏れ防止効果にばらつきが生じ易いという問題がある。また、ゴムパッキンで配管を支持するためゴムパッキンに掛かる負担が大きくなり、長期間の使用により水漏れが生じることがあるという耐久性の問題もある。また、ゴムパッキンで配管を支持するため安定した状態で配管を固定することが難しい。このため、ゴムパッキンが配管の重量等によって下方に引っ張られると、ゴムパッキンが凹んでしまい、その凹みに水が溜まることがある。この結果、ゴムパッキンに汚れが生じやすくなるという問題もある。
【０００７】
【発明の概要】
本発明は、上記問題に対処するためになされたもので、その目的は、水漏れ防止効果に施工によるばらつきが生じず、耐久性に優れ、配管を安定した状態で固定できる配管立上げ構造を提供することである。
【０００８】
上記の目的を達成するため、本発明にかかる配管立上げ構造の構成上の特徴は、床面部に設けられた穴部に配管を通し、穴部の縁部と配管の外周部との間を塞いだ状態で配管を床面部上に起立させて支持する配管立上げ構造であって、穴部の周縁部に密着した状態で穴部に取り付けられ、内部に配管を通すことができる円筒状の固定部材と、配管を通すことができる挿通穴を備え、挿通穴に配管を挿通させた状態で固定部材の上端部に螺合できる蓋部材と、配管の外周部に巻き付けられ、蓋部材を固定部材に螺合させる際に、蓋部材によって固定部材に押し付けられて、固定部材と配管との間および蓋部材と配管との間を閉塞する帯状のシール部材とを備え、記配管の外周部に巻き付けられて円筒状になったシール部材における上端面と下端面とを高摩擦面に形成し、シール部材におけるシール部材同士が対向する面を低摩擦面に形成したことにある。
【０００９】
前記のように構成した本発明の配管立上げ構造では、内部に配管を通す固定部材を床面部の穴部に密着状態で取り付けている。そして、その状態の固定部材の上端部に、配管を挿通穴に挿通させた蓋部材を螺合させている。すなわち、この配管立上げ構造では、配管における床面部を貫通する部分を固定部材と蓋部材とで覆っている。そして、帯状のシール部材を、配管の外周部における蓋部材の下方部分に巻き付けて、固定部材と配管との間および蓋部材と配管との間を閉塞している。
【００１０】
このシール部材は、蓋部材を固定部材に螺合させる際に、配管の外周部に強く巻き付けられるとともに、蓋部材と固定部材とによって上下方向に押し付けられて固定部材と配管との間および蓋部材と配管との間を閉塞する。これによって、配管と、固定部材および蓋部材との間からの水漏れが防止される。また、この場合のシール部材の取り付けは、配管における固定部材と蓋部材との間の部分にシール部材を巻き付けて、固定部材に蓋部材を螺合させるだけであるため容易であるとともに、施工によって水漏れ防止効果にばらつきが生じることがない。
【００１１】
さらに、シール部材は、配管の外周部に巻き付けられた状態で、蓋部材と固定部材とによって押し潰された状態で固定部材と配管との間および蓋部材と配管との間を閉塞するため、配管の大きさに関係なくどのような固定部材を用いても良好な水漏れ防止効果を発揮し得る。このため、固定部材の内径を最大サイズの配管に取り付けることができる大きさに設定しておけば、固定部材は一種類のものだけを用意すれば済む。
【００１２】
また、床面部の穴部は、穴部の周縁部に密着した状態で取り付けられた固定部材によって閉塞されるため、この部分からの水漏れも防止される。この場合の固定部材としては、例えば、穴部の周縁部上面に係合可能なフランジ状の突部を備えた円筒部と、円筒部の突部とで穴部の周縁部を挟んだ状態で円筒部の下端部に螺合可能なリング状のねじとで構成される部材を用いることができる。そして、穴部の周縁部と突部との間および穴部の周縁部とリング状のねじとの間にはシール材を取り付けておくことが好ましい。これによって、穴部の周縁部と固定部材との間をより確実にシールすることができる。
【００１３】
また、この配管立上げ構造によると、配管はシール部材によってシールされた状態で固定部材と蓋部材とによって支持されるため、配管を安定した状態で固定できる。このため、この配管立上げ構造の耐久性が向上し、その結果、低コスト化が可能になる。
【００１４】
また、本発明にかかる配管立上げ構造では、配管の外周部に巻き付けられて円筒状になったシール部材における上端面と下端面とを高摩擦面に形成し、シール部材におけるシール部材同士が対向する面を低摩擦面に形成している。
【００１５】
これによると、蓋部材を固定部材に螺合させる際に、蓋部材の下面とシール部材の上端面との間およびシール部材の下端面とその部分に接触する固定部材の部分との間に滑りが生じ難くなる。また、螺旋状に形成されたシール部材のシール部材同士が接触する部分は滑りやすくなる。このため、シール部材は蓋部材の回転に追従して螺旋方向に伸びながら配管の周囲に巻き付けられて、固定部材と配管との間および蓋部材と配管との間を確実に閉塞する。これによって、確実な水漏れ防止が可能になる。また、この場合のシール部材における上端面と下端面との高摩擦面としては、粗面を形成することによって行うことができる。また、シール部材の低摩擦面としては、滑らかな摺面を形成したり、該当する部分に、グリスなどの潤滑剤を塗って形成したりすることができる。
【００１６】
また、本発明にかかる配管立上げ構造の他の構成上の特徴は、シール部材を、配管の外周部を囲うことのできる円柱状のシール材を螺旋状に切断して形成したことにある。これによると、シール部材を配管に巻き付けた状態でその上端部を蓋部材で押し付けると、シール部材は、周囲が密閉された状態の円柱状になるため、より効果的なシールができるようになる。また、シール部材の配管への取り付け作業も容易になる。また、シール部材を構成するシール材としては、伸縮性や弾性を有するプラスチックやゴムを使用することが好ましい。
【００１７】
本発明にかかる配管立上げ構造では、固定部材の内周面と配管の外周面との間にシール部材を配置するための空間部を設けるとともに、固定部材の内周面にシール部材の下端部を係止するための係止用段部を設けることもできる。これによると、シール部材は、下端部を係止用段部に係止させた状態で上端部が蓋部材によって下方に押し付けられるため、空間部内で安定した姿勢を維持するようになる。このため効果的なシールが長期間にわたって行える。
【００１８】
また、本発明にかかる配管立上げ構造では、直径が蓋部材の挿通穴の直径よりも大きく設定されたフランジ状の突起を備えた継手を、蓋部材の上面側に突起を位置させた状態で、配管の上端部に接続することもできる。これによると、配管は、上端部に接続された継手の突起を蓋部材の上方に位置させた状態で固定部材に固定されるため、下方にずれて行くことがなくなり、より安定した状態で固定される。このため、長期間にわたって効果的なシールが行える。
【００１９】
【発明の実施の形態】
以下、本発明の一実施形態を図面を用いて説明する。図１は、本発明の配管立上げ構造を備えた浴室１０を示している。この浴室１０では、浴室１０内と屋外とを仕切る外側壁面パネル１１に窓１１ａが設けられており、床部における窓１１ａ側部分に浴槽１２が設置されている。そして、浴槽１２の左右（図１では前後）の側面は、左壁面パネル（図示せず）と右壁面パネル１３ａとで挟まれている。また、外側壁面パネル１１に対向する部分には、出入用扉（図示せず）を有する内側壁面パネル１３ｂが設けられ、天井部はドーム状の天井パネル１４で構成されている。
【００２０】
浴槽１２は、図２に示すように、浴槽側フロア１５の上面に設置されている。そして、浴槽側フロア１５の長手方向に沿った一方の縁部には、本発明の床面部としての洗い場側フロア１６が接続されている。また、洗い場側フロア１６の上面における右壁面パネル１３ａに沿った部分にカウンター１７が設けられ、カウンター１７の上方の壁面に鏡１８や収容棚１９等が設けられている。カウンター１７は、浴槽１２の上面部１２ａと略等しい高さに設定されている。
【００２１】
これらの浴室１０を構成する外側壁面パネル１１等の各パネル、浴槽１２、浴槽側フロア１５および洗い場側フロア１６等の各部分の本体部分は、それぞれ樹脂の成形体で構成されている。また、浴槽１２の上面部１２ａにおけるカウンター１７側の角部には、浴槽１２内に湯や水を取り出すための水栓２１が設けられ、カウンター１７の上方の壁面における鏡１８の下方には、カウンター１７で使う湯や水を取り出すための水栓２２が設けられている。
【００２２】
そして、洗い場側フロア１６におけるカウンター１７の下方部分には、水栓２１，２２に湯や水を供給するための本発明の配管としての給湯管２３および給水管２４を支持する配管立上げ構造２０がそれぞれ設けられている。給湯管２３および給水管２４は、ともに可撓性を有する樹脂製の管で構成されており、分配装置（図示せず）を介して屋外に設けられた水道管に連通している。そして、給湯管２３の通路内には加熱装置（図示せず）が設けられており、分配装置を介して水道管から送られる水は、この加熱装置を通過して加熱され給湯管２３を介して水栓２１，２２に供給される。また、給水管２４は、分配装置を介して水道管から送られる水を直接水栓２１，２２に供給する。
【００２３】
給湯管２３は、洗い場側フロア１６に設けられた穴部（図３参照）１６ａを通って洗い場側フロア１６の下方から上方に突出したところで継手２５に接続されている。継手２５は、給湯管２３と略等しい直径に設定された円筒部２５ａと円筒部２５ａの下端外周部に形成されたフランジ状の突起２５ｂとで構成されており、円筒部２５ａの内周面下部側には雌ねじ（図示せず）が設けられている。また、給湯管２３の上端部は細径に形成され、その細径部（図示せず）の外周面に継手２５の雌ねじと螺合する雄ねじが設けられている。このねじ同士の螺合により、給湯管２３と継手２５とは接続されている。
【００２４】
継手２５の上端部は、三方に分岐したＴ型継手２６ａの一方の開口に接続されている。そして、Ｔ型継手２６ａの他の２個の開口にそれぞれ分岐給湯管２３ａ，２３ｂが接続され、分岐給湯管２３ａの先端部が水栓２１に接続され、分岐給湯管２３ｂの先端部が水栓２２に接続されている。また、給水管２４も同様に継手２５および三方に分岐したＴ型継手２６ｂを介して分岐給水管２４ａ，２４ｂに接続されている。
【００２５】
そして、分岐給水管２４ａの先端部が水栓２１に接続され、分岐給水管２４ｂの先端部が水栓２２に接続されている。水栓２１，２２にはそれぞれ湯を取り出すための操作部と水を取り出すための操作部とが備わっており、取り出す湯や水に応じて対応する操作部を操作することにより任意の湯や水を取り出すことができる。
【００２６】
配管立上げ構造２０は、図３に示したように構成されている。この配管立上げ構造２０は、給湯管２３に取り付けられたものも給水管２４に取り付けられたものも同じ構成であるため、ここでは、給湯管２３に取り付けた配管立上げ構造２０について説明する。配管立上げ構造２０は、給湯管２３と、給湯管２３の上端部に接続された継手２５との接続部の近傍部分を支持するとともに、固定するアダプター本体２７、係合リング２８、蓋部材２９およびシール部材３０を備えている。
【００２７】
アダプター本体２７、係合リング２８および蓋部材２９は、１組で１個のアダプター３１を構成する金属製の部材であり、アダプター本体２７と係合リング２８とで本発明の固定部材３２が構成される。アダプター本体２７は、洗い場側フロア１６の穴部１６ａに取り付けることができ、内部に給湯管２３を通すことのできる円筒状に形成されている。そして、アダプター本体２７の内周面の下端部には中心側に突出した係止用段部２７ａが設けられ、外周面のやや上部側部分には外側に突出したフランジ状の突部２７ｂが設けられている。
【００２８】
また、アダプター本体２７の外周面における上部側部分と下部側部分とには、それぞれ雄ねじ２７ｃ，２７ｄが設けられている。係合リング２８は、内周面に、雌ねじ２８ａが設けられたリング状に形成され、雌ねじ２８ａを雄ねじ２７ｄに螺合させることにより、アダプター本体２７の下端部に取り付けられる。アダプター本体２７を上方から穴部１６ａに通して、突部２７ｂを洗い場側フロア１６の上面に位置させた状態で、アダプター本体２７の下方から係合リング２８をアダプター本体２７に取り付けることによりアダプター本体２７と係合リング２８とからなる固定部材３２を穴部１６ａに固定することができる。
【００２９】
この場合、洗い場側フロア１６の上面と突部２７ｂの下面との間には、リング状のパッキン３３を取り付け、洗い場側フロア１６の下面と係合リング２８の上面との間には、リング状のパッキン３４を取り付ける。これによって、穴部１６ａの周縁部と固定部材３２との間が密閉状態になる。
【００３０】
蓋部材２９は、内周面に雄ねじ２７ｃと螺合可能な雌ねじ２９ａが形成されたキャップ状に形成され、上面中央部に、給湯管２３を通すための挿通穴２９ｂが設けられている。このため、蓋部材２９の挿通穴２９ｂに給湯管２３を下方から通し、雌ねじ２９ａを雄ねじ２７ｃに螺合させることにより、蓋部材２９をアダプター本体２７の上端部に取り付けることができる。
【００３１】
シール部材３０は、伸縮可能で弾性を有する架橋ポリエチレンからなっており、通常時は、図４および図５に示したように、円筒体の上端外周の角部を切り欠いた形状になるように構成されている。そして、図６に示したように、シール部材３０の上端部と下端部とを引き離すようにして上下方向に引っ張ると、螺旋状の帯状になるように切断部ａが設けられている。このシール部材３０は、給湯管２３の外周部に巻き付いて給湯管２３を囲った状態で、アダプター本体２７の内部に形成された空間部２７ｅ内に収容できる大きさおよび形状に形成されている。また、シール部材３０の上端面３０ａと下端面３０ｂとは粗面に形成されて摩擦係数が大きくなっており、切断部ａの切断面は滑らかな摺面に形成されて摩擦係数が小さくなっている。
【００３２】
そして、アダプター本体２７の空間部２７ｅ内にシール部材３０を収容して、アダプター本体２７に蓋部材２９を取り付ける際に、シール部材３０は、蓋部材２９によって係止用段部２７ａ側に押し付けられて収縮した状態になる。また、シール部材３０は、蓋部材２９の回転によって、給湯管２３の外周部に強く巻き付けられる。このシール部材３０によって、給湯管２３と蓋部材２９との間および給湯管２３とアダプター本体２７との間が密閉される。
【００３３】
また、洗い場側フロア１６における給水管２４が設けられる部分にも穴部が設けられ、その穴部にアダプター本体２７や蓋部材２９等からなるアダプター３１と同一の構成からなるアダプター３５等が設けられている。このアダプター３５等によって給水管２４は起立した姿勢で固定される。
【００３４】
このように構成された配管立上げ構造２０の組み付けは、つぎのようにして行われる。まず、洗い場側フロア１６の穴部１６ａに固定部材３２を取り付けるための作業が行われる。この作業では、まず、洗い場側フロア１６の上面における穴部１６ａの周囲にパッキン３３を設置する。そして、そのパッキン３３の上面に突部２７ｂを合わせてアダプター本体２７の下部側部分を上方から穴部１６ａ内に通す。
【００３５】
つぎに、穴部１６ａの下方に突出したアダプター本体２７の下部側部分の外周部にパッキン３４を取り付け、その状態のアダプター本体２７の下部側部分に、雄ねじ２７ｄと雌ねじ２８ａとを螺合させることにより、係合リング２８を取り付ける。この雄ねじ２７ｄと雌ねじ２８ａとを強く締め付けることにより、固定部材３２はより強固に洗い場側フロア１６に固定され、穴部１６ａの周縁部と固定部材３２との間はより確実に密閉される。
【００３６】
つぎに、加熱装置を介して水道管側から延ばされてきた給湯管２３の先端部をアダプター本体２７の内部に通して、洗い場側フロア１６の下方側から上方側に向かって突出させる。ついで、給湯管２３における洗い場側フロア１６の上面から突出した部分にシール部材３０を巻き付け、その状態のシール部材３０を空間部２７ｅ内に収容する。つぎに、蓋部材２９の挿通穴２９ｂに給湯管２３を通して、給湯管２３の外周部に蓋部材２９を取り付ける。
【００３７】
そして、蓋部材２９を軸回りに回転させて、雄ねじ２７ｃと雌ねじ２９ａとを螺合させることにより、蓋部材２９をアダプター本体２７に取り付け、給湯管２３の先端部に継手２５を取り付ける。この際、シール部材３０は、蓋部材２９の回転にともなって絞られるようにして給湯管２３の外周部により強く巻き付けられる。また、雄ねじ２７ｃと雌ねじ２９ａとの螺合により下降してくる蓋部材２９によって、係止用段部２７ａ側に押し付けられて収縮した状態になる。このシール部材３０によって、給湯管２３と蓋部材２９との間および給湯管２３とアダプター本体２７との間が密閉される。
【００３８】
このようにして、給湯管２３の上端部は、水漏れを防止された状態で起立した姿勢に固定される。また、給水管２４の上端部も、同様にして、洗い場側フロア１６に固定される。そして、給湯管２３に接続された継手２５にＴ型継手２６ａを介して、分岐給湯管２３ａ，２３ｂを接続し、給水管２４に接続された継手２５にＴ型継手２６ｂを介して分岐給水管２４ａ，２４ｂを接続する。これによって、水道管と水栓２１，２２との間が接続され、水栓２１，２２は使用可能な状態になる。
【００３９】
入浴のために、浴槽１２内に湯を入れる場合には、まず、水栓２１が備える各操作部を操作して湯温を調節して水栓２１から湯を吐出させる。そして、湯面が適当な高さになったときに給湯を停止して入浴する。また、カウンター１７の前で、洗髪や体の洗浄をするために、湯や水を使用する場合には、水栓２２が備える各操作部を操作して、適度の温度に調節した湯や水を、水栓２２から取り出して使用する。
【００４０】
その際、給湯管２３は、配管立上げ構造２０によって起立姿勢を維持され、加熱装置側から送られる湯を、Ｔ型継手２６ａを介して分岐給湯管２３ａ，２３ｂに送る。また、給水管２４も、配管立上げ構造２０によって起立姿勢を維持され、水道管側から分配装置を介して直接送られる水を、Ｔ型継手２６ｂを介して分岐給水管２４ａ，２４ｂに送る。この際、給湯管２３や給水管２４は湯や水の供給による振動で移動することなく安定した状態に固定され、湯や水を水栓２１，２２に供給する。また、配管立上げ構造２０から給湯管２３や給水管２４の湯水が漏れることが防止される。
【００４１】
このように、本発明にかかる配管立上げ構造２０では、蓋部材２９をアダプター本体２７に取り付ける際に、給湯管２３や給水管２４の外周部に強く巻き付けられるとともに、蓋部材２９と係止用段部２７ａとによって上下方向に押し付けられるシール部材３０を用いている。これによって、給湯管２３と蓋部材２９との間および給湯管２３とアダプター本体２７との間が閉塞され、給湯管２３等とアダプター３１との間からの水漏れが防止される。また、洗い場側フロア１６の穴部１６ａは、固定部材３２とパッキン３３，３４によって閉塞されるため、この部分からの水漏れも防止される。
【００４２】
また、この場合のシール部材３０の取り付けは、給湯管２３等にシール部材３０を巻き付けて、アダプター本体２７に蓋部材２９を取り付けるだけであるため簡単であるとともに、施工によって水漏れ防止効果にばらつきが生じることがない。また、シール部材３０の上端面３０ａと下端面３０ｂとが高摩擦面に形成され、切断部ａの切断面が低摩擦面に形成されているため、シール部材３０はスムーズに給湯管２３等に巻き付けられる。
【００４３】
さらに、シール部材３０は、給湯管２３等に巻き付けられた状態で、蓋部材２９と係止用段部２７ａとによって押し潰された状態で給湯管２３と蓋部材２９との間および給湯管２３とアダプター本体２７との間を閉塞するため、給湯管２３等の大きさに関係なくどのようなアダプター３１を用いても良好な水漏れ防止効果を発揮し得る。
【００４４】
このため、アダプター３１を最大サイズの給湯管２３等に合わせて製造しておけば、アダプター３１は一種類の大きさのものだけで済む。また、シール部材３０が円筒状のシール材を螺旋状に切断して形成されたもので、通常時は、円筒状に維持されているため、給湯管２３等への取り付け作業が容易である。さらに、給湯管２３等に接続された継手２５に突起２５ｂが設けられているため、給湯管２３等を安定した状態で固定することができるとともに、給湯管２３等と継手２５との接続部の位置にずれが生じない。この結果、長期間にわたって効果的なシールが行える。
【００４５】
また、本発明による配管立上げ構造は、前述した実施形態以外についても技術的範囲内で適宜変更実施が可能である。例えば、前述した実施形態では、シール部材３０を架橋ポリエチレンで構成したが、このシール部材３０を構成する材料としては、クロロブレンゴムやエチレンプロピレンゴム等のゴムやその他伸縮可能な弾性材料で構成することができる。また、前述した実施形態では、シール部材３０を円筒状のシール材を螺旋状に切断して形成しているが、これに代えて直線状になった帯状のシール材を用いてもよい。
【００４６】
さらに、前述したシール部材３０では切断部ａの切断面を滑らかな摺面に形成することにより、低摩擦面を形成しているが、この部分にグリスなどの潤滑剤を塗布することにより低摩擦面を形成してもよい。また、グリスなどの潤滑剤を摩擦係数の低下のためだけでなく、シール効果を向上させるために用いることもできる。さらに、配管立上げ構造２０を構成する各部材の材料や構造についても適宜変更実施が可能である。また、前述した実施形態では、配管立上げ構造２０等を浴室１０で使用しているが、本発明にかかる配管立上げ構造は、浴室に限らず、トイレ、洗面所、台所等の湯や水を使用する種々の場所で使用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pipe start-up structure that supports a pipe extending through a hole provided in a floor surface portion and extending indoors from the outdoor side in an upright state on the floor surface portion.
[0002]
[Prior art]
Conventionally, a faucet and a water intake for taking out water and hot water are provided in each place in the house such as a bathroom, a toilet, a washroom, and a kitchen. This faucet or the like is connected to a pipe for supplying water indoors by separating it from a water supply pipe provided outside, and this pipe passes through a hole provided in the floor portion. It is extended to a predetermined place. As such pipes, resin pipes that are generally flexible and inexpensive in terms of workability and cost are used.
[0003]
And the part located in the hole part of the floor part in piping is in the posture which stood on the floor part in the state where a waterproof structure was provided between the peripheral part of the hole part, and water leakage did not occur. It is fixed. There is a structure using a rubber packing and a hose band as a pipe start-up structure capable of fixing the pipe in an upright posture and preventing water leakage from a hole provided in the floor (see, for example, Patent Document 1). .
[0004]
In this pipe start-up structure, a rubber packing having an insertion hole for inserting a pipe is attached to a hole provided in the floor, and the tip of the pipe is passed through the hole in the floor and the insertion hole in the rubber packing. It protrudes above the surface part. Then, a portion near the insertion hole of the rubber packing is wound around the outer peripheral portion of the pipe, and the portion is fastened with a hose band to fix the pipe to the rubber packing in an upright state.
[0005]
[Patent Document 1]
JP-A-10-152873 Publication [0006]
[Problems to be solved by the invention]
However, the above-described conventional pipe start-up structure has a problem that variations in the water leakage prevention effect are likely to occur due to the construction of attaching the hose band. In addition, since the piping is supported by the rubber packing, a burden on the rubber packing is increased, and there is a problem of durability that water leakage may occur due to long-term use. Further, since the pipe is supported by the rubber packing, it is difficult to fix the pipe in a stable state. For this reason, when the rubber packing is pulled downward due to the weight of the pipe or the like, the rubber packing is recessed, and water may accumulate in the recess. As a result, there is also a problem that the rubber packing is easily contaminated.
[0007]
SUMMARY OF THE INVENTION
The present invention was made in order to address the above problems, and its purpose is to provide a pipe start-up structure that does not cause variations in construction due to water leakage prevention effects, has excellent durability, and can fix pipes in a stable state. Is to provide.

In order to achieve the above object, the structural features of the pipe start-up structure according to the present invention are as follows: the pipe is passed through the hole provided in the floor surface, and the gap between the edge of the hole and the outer periphery of the pipe A pipe start-up structure that supports a pipe standing upright on the floor surface in a closed state, and is attached to the hole in close contact with the peripheral edge of the hole, and is a cylindrical shape that allows the pipe to pass inside A fixing member and an insertion hole through which piping can be passed, and a lid member that can be screwed onto the upper end of the fixing member in a state where the piping is inserted through the insertion hole, and the outer periphery of the piping are wound around to fix the lid member when screwed into the member, pressed against the fixing member by the lid member, e Bei a and between the lid member and the stationary member and the pipe and the band-shaped sealing member for closing the space between the pipes, the serial peripheral portion of the pipe The upper and lower surfaces of a cylindrical seal member wrapped around Forming the door to the high friction surface, the sealing member between the sealing member is in the formation of the surface facing the low friction surface.
[0009]
In the pipe start-up structure of the present invention configured as described above, the fixing member that allows the pipe to pass therethrough is attached in close contact with the hole of the floor portion. And the cover member which penetrated piping to the penetration hole is screwed together by the upper end part of the fixing member of the state. That is, in this pipe start-up structure, the part that penetrates the floor surface part in the pipe is covered with the fixing member and the lid member. And the strip | belt-shaped sealing member is wound around the lower part of the cover member in the outer peripheral part of piping, and the space | interval between a fixing member and piping and between a cover member and piping is obstruct | occluded.
[0010]
The seal member is strongly wound around the outer peripheral portion of the pipe when the lid member is screwed to the fixing member, and is pressed in the vertical direction by the lid member and the fixing member, and between the fixing member and the pipe and the lid member. Block between the pipe and the pipe. Thereby, water leakage from between the piping and the fixing member and the lid member is prevented. In this case, the seal member can be easily attached by simply winding the seal member around the portion of the piping between the fixing member and the lid member and screwing the lid member to the fixing member. There is no variation in the water leakage prevention effect.
[0011]
Furthermore, the sealing member is in a state of being wound around the outer peripheral portion of the pipe and is closed between the fixing member and the pipe and between the lid member and the pipe while being crushed by the lid member and the fixing member. Regardless of the size of the piping, any fixing member can be used to exert a good water leakage prevention effect. For this reason, if the inner diameter of the fixing member is set to a size that can be attached to the maximum size pipe, only one type of fixing member needs to be prepared.
[0012]
Moreover, since the hole part of a floor part is obstruct | occluded by the fixing member attached in the state closely_contact | adhered to the peripheral part of a hole part, the water leak from this part is also prevented. As a fixing member in this case, for example, in a state in which the peripheral portion of the hole portion is sandwiched between the cylindrical portion having a flange-like protrusion that can be engaged with the upper surface of the peripheral portion of the hole portion and the protruding portion of the cylindrical portion. A member constituted by a ring-shaped screw that can be screwed into the lower end of the cylindrical portion can be used. And it is preferable to attach a sealing material between the peripheral part of a hole part and a protrusion, and between the peripheral part of a hole part and a ring-shaped screw. As a result, the gap between the peripheral edge of the hole and the fixing member can be more reliably sealed.
[0013]
Further, according to this pipe start-up structure, since the pipe is supported by the fixing member and the lid member while being sealed by the seal member, the pipe can be fixed in a stable state. For this reason, the durability of the pipe start-up structure is improved, and as a result, the cost can be reduced.
[0014]
Further, in the pipe start-up structure according to the present invention, the upper end surface and the lower end surface of the cylindrical seal member wound around the outer periphery of the pipe are formed as high friction surfaces, and the seal members in the seal member face each other. The surface to be formed is a low friction surface.
[0015]
According to this, when the lid member is screwed into the fixing member, the sliding between the lower surface of the lid member and the upper end surface of the sealing member and between the lower end surface of the sealing member and the portion of the fixing member that contacts the portion. Is less likely to occur. Moreover, the part where the sealing members of the sealing member formed in a spiral form are slippery. For this reason, the seal member is wound around the pipe while extending in the spiral direction following the rotation of the cover member, and reliably closes the space between the fixing member and the pipe and between the cover member and the pipe. This makes it possible to reliably prevent water leakage. Moreover, it can carry out by forming a rough surface as a high friction surface of the upper end surface in a sealing member in this case, and a lower end surface. Further, as the low friction surface of the seal member, a smooth sliding surface can be formed, or a lubricant such as grease can be applied to the corresponding portion.
[0016]
Another structural feature of the pipe start-up structure according to the present invention is that the sealing member is formed by cutting a cylindrical sealing material that can surround the outer peripheral portion of the pipe in a spiral shape. According to this, when the upper end of the seal member is pressed with a lid member in a state where the seal member is wound around the pipe, the seal member becomes a cylindrical shape in which the periphery is sealed, so that a more effective seal can be achieved. . In addition, it is easy to attach the seal member to the pipe. Moreover, as a sealing material which comprises a sealing member, it is preferable to use the plastics and rubber | gum which have elasticity and elasticity.
[0017]
In the pipe start-up structure according to the present invention, a space for arranging the seal member is provided between the inner peripheral surface of the fixing member and the outer peripheral surface of the pipe, and the lower end portion of the seal member is provided on the inner peripheral surface of the fixing member. It is also possible to provide a locking step for locking. According to this, since the upper end portion is pressed downward by the lid member in a state where the lower end portion is locked to the locking stepped portion, the seal member maintains a stable posture in the space portion. For this reason, effective sealing can be performed over a long period of time.
[0018]
Further, in the pipe start-up structure according to the present invention, the joint provided with the flange-like protrusion whose diameter is set larger than the diameter of the insertion hole of the lid member is in a state where the protrusion is positioned on the upper surface side of the lid member. It can also be connected to the upper end of the pipe. According to this, since the pipe is fixed to the fixing member in a state where the projection of the joint connected to the upper end portion is positioned above the lid member, the pipe does not shift downward and is fixed in a more stable state. Is done. For this reason, effective sealing can be performed over a long period of time.

At this time, the seal member 30 is tightly wound around the outer peripheral portion of the hot water supply pipe 23 so as to be squeezed as the lid member 29 rotates. Further, the lid member 29 descends by the screwing of the male screw 27c and the female screw 29a and is pressed against the locking step portion 27a to be in a contracted state. The seal member 30 seals between the hot water supply pipe 23 and the lid member 29 and between the hot water supply pipe 23 and the adapter main body 27.
[0038]
In this way, the upper end portion of the hot water supply pipe 23 is fixed in an upright posture while preventing water leakage. Further, the upper end portion of the water supply pipe 24 is also fixed to the wash floor 16 in the same manner. And the branch hot water supply pipes 23a and 23b are connected to the joint 25 connected to the hot water supply pipe 23 via the T type joint 26a, and the branch water supply pipe is connected to the joint 25 connected to the water supply pipe 24 via the T type joint 26b. 24a and 24b are connected. As a result, the water pipe and the faucets 21 and 22 are connected, and the faucets 21 and 22 are ready for use.
[0039]
When hot water is poured into the bathtub 12 for bathing, first, the operation part provided in the faucet 21 is operated to adjust the hot water temperature, and hot water is discharged from the faucet 21. Then, when the hot water surface has reached an appropriate height, the hot water supply is stopped and the bath is taken. In addition, when using hot water or water in front of the counter 17 for washing hair or washing the body, the hot water or water adjusted to an appropriate temperature by operating each operation part of the faucet 22 is used. Is removed from the water tap 22 and used.
[0040]
At that time, the hot water supply pipe 23 is maintained in the standing posture by the pipe rising structure 20, and the hot water sent from the heating device side is sent to the branched hot water supply pipes 23a and 23b via the T-shaped joint 26a. Further, the water supply pipe 24 is also maintained in the standing posture by the pipe rising structure 20 and sends water directly sent from the water pipe side via the distribution device to the branch water supply pipes 24a and 24b via the T-shaped joint 26b. At this time, the hot water supply pipe 23 and the water supply pipe 24 are fixed in a stable state without being moved by vibration caused by the supply of hot water or water, and supply hot water or water to the water taps 21 and 22. Further, the hot water in the hot water supply pipe 23 and the water supply pipe 24 is prevented from leaking from the pipe startup structure 20.
[0041]
As described above, in the pipe start-up structure 20 according to the present invention, when the lid member 29 is attached to the adapter main body 27, it is strongly wound around the outer periphery of the hot water supply pipe 23 and the water supply pipe 24, and is engaged with the lid member 29. A seal member 30 that is pressed in the vertical direction by the stepped portion 27a is used. As a result, the space between the hot water supply pipe 23 and the lid member 29 and the space between the hot water supply pipe 23 and the adapter main body 27 are closed, and water leakage between the hot water supply pipe 23 and the adapter 31 is prevented. Moreover, since the hole 16a of the wash floor 16 is closed by the fixing member 32 and the packings 33 and 34, water leakage from this portion is also prevented.
[0042]
Also, the attachment of the seal member 30 in this case is simple because the seal member 30 is simply wrapped around the hot water supply pipe 23 and the like, and the lid member 29 is attached to the adapter main body 27. Will not occur. Moreover, since the upper end surface 30a and the lower end surface 30b of the sealing member 30 are formed in a high friction surface, and the cutting surface of the cutting part a is formed in a low friction surface, the sealing member 30 is smoothly connected to the hot water supply pipe 23 and the like. Wrapped.
[0043]
Further, the seal member 30 is wound around the hot water supply pipe 23 and the like, and is crushed by the lid member 29 and the locking step portion 27a, and between the hot water supply pipe 23 and the cover member 29 and the hot water supply pipe 23. Since the gap between the adapter body 27 and the adapter main body 27 is closed, a good water leakage preventing effect can be exhibited regardless of the size of the hot water supply pipe 23 or the like.
[0044]
For this reason, if the adapter 31 is manufactured according to the hot water supply pipe 23 or the like of the maximum size, the adapter 31 is only required to have one size. Further, the sealing member 30 is formed by cutting a cylindrical sealing material into a spiral shape, and is normally maintained in a cylindrical shape, so that it can be easily attached to the hot water supply pipe 23 and the like. Furthermore, since the projection 25b is provided on the joint 25 connected to the hot water supply pipe 23 and the like, the hot water supply pipe 23 and the like can be fixed in a stable state, and the connection portion between the hot water supply pipe 23 and the joint 25 can be fixed. The position does not shift. As a result, effective sealing can be performed over a long period of time.
[0045]
Further, the pipe start-up structure according to the present invention can be modified as appropriate within the technical scope other than the embodiment described above. For example, in the embodiment described above, the seal member 30 is made of crosslinked polyethylene, but the material constituting the seal member 30 is made of rubber such as chlorobrene rubber or ethylene propylene rubber, or other elastic material that can be stretched. be able to. In the above-described embodiment, the sealing member 30 is formed by cutting a cylindrical sealing material into a spiral shape, but a linear strip-shaped sealing material may be used instead.
[0046]
Furthermore, in the sealing member 30 described above, a low friction surface is formed by forming the cut surface of the cutting portion a as a smooth sliding surface. However, by applying a lubricant such as grease to this portion, low friction is achieved. A surface may be formed. Further, a lubricant such as grease can be used not only for reducing the friction coefficient but also for improving the sealing effect. Further, the material and structure of each member constituting the pipe start-up structure 20 can be appropriately changed. Moreover, in embodiment mentioned above, although the pipe starting structure 20 grade | etc., Is used in the bathroom 10, the pipe starting structure concerning this invention is not restricted to a bathroom, hot water and water, such as a toilet, a washroom, and a kitchen. Can be used in various places where
