Description
請求項1〜請求項3のいずれか一項の発明を前提とする請求項4の発明では、前記各加熱体の両側面にフッ素樹脂コーティングシートを取着するかまたはフッ素樹脂コーティング加工を施している。従って、その側面を保温材の端面から分離させ易い。
請求項7の発明にかかる保温材付き流体管における保温材接合方法においては、内管の外表面を保温材により被覆した状態で、内管の周方向両側で内管の長手方向に沿って両端面間にわたり延びる両切込みを形成した保温材において内管の周方向で相対向する両切込面を熱溶融した後、この両切込面を互いに熱融着して接合した継ぎ目を設け、次に、請求項6に記載の保温材付き流体管における保温材接合方法により両保温材の端面を互いに熱融着して接合した継ぎ目を設ける。従って、施工時に保温材を内管の外周に挿通し易いとともに、保温材の継ぎ目に隙間が生じにくい。
ホルダ1の頭部1aの外側には加熱部材2が取り付けられている。この加熱部材2は、この頭部1aから一体的に延設された腕部3に対し取着された上側の加熱体4と、この頭部1aで回動中心部としての支軸5により上下方向へ回動可能に支持された腕部6に対し取着された下側の加熱体7とを備えている。上側の加熱体4と下側の加熱体7とは、それぞれ、半円の外周縁を有する板状をなし、加熱し易い金属等を主体として形成されている。支軸5の回動中心線5aを中心とする回動方向Xで相対向する上下両加熱体4,7の割縁部8には半円状の割孔9が形成されている。
図3(a)に示すように、発泡ポリエチレン等の断熱材からなる円筒状の保温材22により、樹脂や銅等からなる内管23の外表面23aを被覆した流体管M1,M2は、内管23の長手方向の両側で分断されている。内管23の外表面23aと保温材22の内周面との間に隙間Gをあけることにより、拡管部や曲がり部において内管23を保温材22に挿通し易くしている。これらの流体管M1,M2を互いに接続する際には、まず、図3(b)に示すように、内管23に対し保温材22を長手方向へ移動させて両保温材22の相対向する端面22aを互いに離すとともに、両保温材22間で露出した内管23を互いに連結する。次に、図1,2に示す前記熱融着具の加熱部材2を開状態Pにして上下両加熱体4,7の割縁部8間で挿脱許容空間Sに内管23を挿入した後、この加熱部材2を閉状態Qにすると、内管23が挿通孔15に嵌め込まれる。その後、図3(c)に示すように加熱部材2における上下両加熱体4,7の両側面16に両保温材22の端面22aを押し当てると、それらの端面22aが同時に加熱されて溶融される。次に、加熱部材2を開状態Pにして上下両加熱体4の割縁部8間の挿脱許容空間Sから内管23を離脱させると、図3(d)に示すように、溶融状態にある両保温材22の端面22aが長手方向で相対向する。上下両加熱体4,7の側面16にはフッ素樹脂コーティング加工が施されているため、その側面16を保温材22の端面22aから分離させ易い。この側面16にはフッ素樹脂コーティングシートを耐久性低下に応じて張替え可能に取着してもよい。このようにして熱融着具の加熱部材2を両保温材22の端面22aから取り外した後瞬時に、溶融状態にある両保温材22の端面22aを互いに押し当てると、図4に示すように、その両端面22aが互いに熱融着されて接合され、内管23の外周全体に熱融着による継ぎ目24が生じる。
* 両保温材22の端面22aは互いに熱融着されて接合されているので、それらの端面22aが互いに分離しにくくなり、両保温材22間の継ぎ目24に隙間が生じにくくなる。従って、内管23の外表面23aに結露が生じにくくなって漏水の発生を防止することができる。その継ぎ目24においては、内管23の外周全体で両保温材22の端面22aが熱融着されているので、隙間がより一層生じにくくなる。
* 加熱部材2における加熱手段としては、熱線によるヒータ17に代えて、上下両加熱体4,7の側面16を加熱することができるものであればよく、例えば、その側面16に形成した多数の小孔からガスによる熱風を噴出させたり、ヒータ17の電源を電池にしたりすることができる。また、タングステンやモリブデンの粉末をペースト状にしてアルミナの全面に略均一に印刷したものを上記熱線に代わる抵抗体として採用する。
* 加熱部材2に対する開閉操作手段10としては、前述したリンク機構に代えて、上下両加熱体4,7を互いに開閉させることができる指当て摘みを設ける。
