Description

【考案の詳細な説明】
【０００１】
【産業上の利用分野】
本考案は、合成樹脂管同士を突き合わせて簡単に融着接合できる電熱線を内蔵 した管継手に関する。
【０００２】
【従来の技術とその課題】
本件出願人は、先に実開平３ー２５０９６号公報で、継手本体の中央部外周に フランジを設けると共に該フランジの両側に受口と差口を設け、前記フランジの 側面、受口の内周面および差口の外周面に電熱線を埋設した管継手を提案した。 しかしながら、この管継手は合成樹脂管の側壁から分岐管を取り出すときに用い るものであって、合成樹脂管同士を突き合わせ接続する場合には使用できなかっ た。このため、この種の配管施工分野では合成樹脂管同士を突き合わせてから簡 単に融着接合できる管継手の開発が望まれていた。
【０００３】 本考案はかかる要望に則したものであって、合成樹脂管同士を突き合わせ接続 してから電熱線に通電するだけで簡単、かつ確実に融着接合できる管継手を提供 するものである。
【０００４】
【課題を解決するための手段】
本考案は、合成樹脂製継手本体の中央部外周にフランジを設け、該フランジの 両側に差口を設けると共に、それぞれの差口の外周面に電熱線を所定間隔で螺旋 状に埋設したことを特徴とするものである。
【０００５】
【作用】
継手本体の両側に設けた差口の外周面に電熱線を埋設したので、それぞれの差 口に合成樹脂管の端部を外挿してから電熱線に通電すると、差口の外周面と合成 樹脂管の端部内周面とが溶融して融着接合する。
【０００６】
【実施例】
以下、本考案を図面にて詳細に説明する。 図１は本考案の一実施例を示す管継手の縦断面図、図２は図１に示した管継手に 合成樹脂管を接続した状態を示す縦断面図である。 図中１はポリエチレン、ポリプロピレン、ポリブテン等の合成樹脂からなる継手 本体であって、該継手本体１の中央部外周にはフランジ１２が設けられている。 フランジ１２の両側には合成樹脂管４の端部が外挿される差口１１が設けられて おり、該差口１１の外周面は先窄まり状のテーパ面に形成されている。
【０００７】 即ち、差口１１の外周面は先端部の外径が合成樹脂管４の内径よりも若干小径で 、フランジ１２の近傍位置で合成樹脂管４の内径よりも若干大径となるテーパ面 に形成されている。従って、合成樹脂管４の端部を差口１１に外挿してから強く 押し込むと、合成樹脂管４の端面がフランジ１２の側面と隙間なく当接する。
【０００８】 また、差口１１の外周面には電熱線２が所定間隔で螺旋状に埋設されており、該 電熱線２の両端部はフランジ１２の外面に設けたコネクター３のピン３１と接続 している。尚、図１には差口１１の外周面にのみ電熱線２を埋設したものを例示 したが、フランジ１２の側面まで連続して電熱線２を埋設してもよい。
【０００９】 本考案の管継手は以上の構成からなるので、この管継手に合成樹脂管４を接続 する場合、図２に示した如く継手本体１の両側に設けた差口１１にそれぞれの合 成樹脂管４の端部を外挿し、管端面がフランジ１２に当接するまで押し込む。そ こで、コネクター３に電力線を接続し、電熱線２に通電して発熱させる。このと き、合成樹脂管４のサイズに応じて予め定められた電流を電熱線２に所定時間流 すと、差口１１の外周面及び合成樹脂管４の端部内周面が過不足なく同時に溶融 し、両者が強固に融着接合する。また、フランジ１２の側面まで連続して電熱線 ２が埋設されている場合には、該電熱線２の発熱によって合成樹脂管４の端面と フランジ１２の側面とが強固に融着接合する。
【００１０】
【考案の効果】
以上詳述した如く、本考案の管継手は合成樹脂製継手本体の両側に差口を設け ると共に、該差口の外周面に電熱線を埋設したので、それぞれの差口に合成樹脂 管の端部を外挿してから電熱線に通電するだけで、合成樹脂管同士を簡単、かつ 確実に融着接合することができる。

面図である。
【図２】図２は、図１に示した管継手に合成樹脂管を接
続した状態を示す縦断面図である。
