【発明の属する技術分野】
本発明は水道管又はヒーター付き水道管を収納して気温から断熱保護する水道管用養生管に関する。
【０００２】
【従来の技術】
従来、水道管が気温の影響を受けないように収納して、断熱保護する養生管が使用されている。特に、寒冷地では建物の外部に配置する水道管の凍結を防止するため、その外周にニクロム線のヒーターコードを巻き付けた後に、その外側に養生管を施工する。その際には、図７に示すように養生管をほぼ同一形状、構造の２等分割型にする。そして、その各管部材１（１ａ、１ｂ）を本体２とそこに一体に施した外装３との二重構造にし、その本体２には接触面４に水道管又はヒーター付き水道管収納用凹所５を一端面から他端面まで貫いて設けた断熱材を用い、その外装３にはプラスチック製シートを用いる。すると、施工時に両管部材１の対となる収納用凹所５内に水道管６又はヒーター７付き水道管６を収納し、その接触面４同士を合せ結合して管体にし、養生管を形成できる。なお、両管部材１を結合するため、一方の例えば管部材１ｂの接触面４の両端に内面に接着剤を貼付したシート状の結合用突部８（８ａ、８ｂ）を夫々設けておく。
【０００３】
このような養生管を一般的施工方法によって水道管に施工する場合、一端に取付部９を設け、他端に巻付部１０を設けた金属製ブラケット１１を用いる。そして、先ずブラケット１１毎に、そのブラケット１１の取付部９を水道管配置箇所の付近にある建物の外壁、躯体等に固定して取り付ける。次に、そのブラケット１１の巻付部１０を水道管６の外周に１回り巻き付けて、ブラケット１１で水道管６を支持する。その後、水道管６に養生管の施工を行なう、或いは水道管６にヒーター７を巻き付けた後に、養生管の施工を行なうという工程を踏む。それ故、養生管を構成する管部材１の少なくとも一方、例えば管部材１ａを一部切り欠いて、ブラケット１１の腕部１２が通るブラケット設置穴１３を形成しなければならない。なお、養生管を用いない場合には、水道管６にヒーター７を巻き付けた後、更にそれ等の上に断熱材シートを巻き付けてビニールテープ等で留める。
【０００４】
しかし、このように管部材１に大きなブラケット設置穴１３を設けると、外部の冷気がその穴１３から直接入り込んで水道管６に接触し、同時に冷気の温度がブラケット１１を介して水道管６に伝達する。それ故、養生管施工による断熱作用が損なわれ易い。又、養生管施工が複雑化し、施工時間が長くなり易い。しかも、養生管の外装３としてプラスチック製シートを施しておくと、その外装３が短期間の内に劣化し易く、外装３に穴が開き、又めくれて内部の断熱材２が露出して外観が悪くなる。
【０００５】
そこで、本出願人は平成１４年１２月２６日付けの特許出願により、金属外装を施し、接触面の中央に水道管又はヒーター付き水道管を収納する収納用凹所を一端面から他端面まで貫いて設けた断熱材からなる管部材を２個用いて対にし、施工時に両管部材の対となる収納用凹所内に水道管又はヒーター付き水道管を収納し、その両接触面同士を合せ結合して管体を形成する水道管用金属外装養生管と、一端に取付部を設け、他端に巻付部を設けたブラケットを用い、そのブラケットの取付部を水道管配置箇所の付近に固定し、その巻付部を水道管又はヒーター付き水道管を収納した金属外装養生管の外周の少なくとも一部に巻き付けて施工する水道管用金属外装養生管施工方法とを提示した。
【０００６】
そして、この金属外装養生管の施工方法によると、最初に水道管配置箇所に沿って複数のブラケットを取り付ける。次に、一方の管部材を各ブラケットの巻付部の一部内に入れ、その巻付部によって支持する。そして、その管部材の収納用凹所に水道管又はヒーター付き水道管を収納し、更に他方の管部材を各ブラケットの巻付部の同一部分内に入れ、やはりその巻付部によって支持する。最後に、両管部材の接触面同士を合せ、その両合せ目を片面に接着剤を貼付したアルミニウム等の金属テープを用いて塞ぐ。すると、管体が形成できて養生管の本体が完成する。そこで、ブラケットの巻付部の一部で支えた養生管上に、その巻付部の他の部分を夫々被せ、養生管を固定する。それ故、複数のブラケットにて養生管を良好に支持できる。

【発明が解決しようとする課題】
しかしながら、このような金属外装養生管施工方法では、施工時に水道管又はヒーター付き水道管を管部材の収納用凹所内に固定せずに入れ、施工後もそのまま養生管内に収納しておくだけである。それ故、管部材による水道管又はヒーター付き水道管に対する支持が不十分なため施工し難く、施工後も養生管による支持が不十分になり易い。
【０００９】
本発明はこのような従来の問題点に着目してなされたものであり、外装の強度を増して養生管の強度を大きくし、ブラケット設置穴を大きく開ける必要をなくして、断熱作用に優れ、施工が容易で、施工時間が短く、外装が劣化し難く、長期間経過しても外観を損なわずに維持でき、水道管の施工が容易で、水道管の支持状態が良好な水道管用金属外装養生管を提供することを目的とする。
【００１０】
【課題を解決するための手段】
上記目的を達成するために、本発明による水道管用金属外装養生管は、金属外装を施し、接触面の中央部に水道管又はヒーター付き水道管を収納する収納用凹所を少なくとも一箇所、一端面から他端面まで貫いて設けた断熱材からなる管部材を２個用いて対にし、施工時に両管部材の収納用凹所内に水道管又はヒーター付き水道管を収納し、その両接触面同士を合せ結合して管体を形成する水道管用養生管であって、上記一方の管部材の外周に、一端に取付部を設け、他端に巻付部を設けたブラケットの巻付部の一部を巻き付け、その巻付部の一部の位置と一致する管部材の収納用凹所内の位置に水道管支持具を配置し、そのブラケットの巻付部と管部材と水道管支持具とを結合部材を用いて一体に結合する。
【００１１】
又、上記水道管支持具として、壁部に水道管挿入開口を設け、内部を水道管又はヒーター付き水道管の一部を収納する収納部にする筒状ばね体を用いると好ましくなる。
【００１３】
【発明の実施の形態】
以下、添付の図１〜６を参照して、本発明の実施の形態を説明する。
図１は本発明を適用したストレート水道管用金属外装養生管の施工過程を示す斜視図、図２はその金属外装養生管を構成する一方の管部材の水道管又はヒーター付き水道管を収納する収納用凹所内に備え付ける水道管支持具を示す斜視図、図３はその金属外装養生管の施工に用いるブラケットを示す斜視図である。このストレート水道管用金属外装養生管は、図１に示すように外装１４を施した本体１５からなる二重構造の管体にして、２等分割型にする。しかも、各管部材１６（１６ａ、１６ｂ）の外装１４には強度を大きくするため、アルミニウム、ステンレス等の金属体例えば厚みが０．１〜０．２ｍｍ程の半円筒体を用いる。その際、アルミニウム製の半円筒体を用いると、比較的柔らかであるため、切断等の加工が容易であり好都合となる。
【００１４】
そして、本体１５には例えば従来と同様の接触面１７の中央に水道管６又はヒーター７付き水道管６を収納する収納用の凹所１８を一端面から他端面まで貫いて設けた断熱材、例えばポリウレタン等のプラスチック製発泡断熱材を用いる。なお、各管部材１６の製造工程で外装１４を本体１５に施す際には、本体１５の接触面１７に臨む外装１４の両縁部をいずれも少し折り曲げて、接触面１７に夫々差し入れる。しかし、リサイクルに備えて外装１４と本体１５との接着箇所を少なくし、両者を分離し易くしておく。
【００１５】
又、水道管６又はヒーター付き７水道管６の施工用に、一方の管部材１６ａの収納用凹所１８内に備え付けて、水道管６又はヒーター７付き水道管６の一部を支持するための水道管支持具として、例えば図２に示すような筒状ばね体１９を用いる。この筒状ばね体１９は壁部に水道管挿入開口２０を設け、内部を水道管６又はヒーター７付き水道管６の一部を収納する収納部２１にした筒状ばね２２を本体とし、その外側中央にナット状の受部２３を備える。なお、本体に筒状ばね２２を用いているので、その水道管挿入開口２０を開くように両側部に力を加えると、当然、その両側部から挿入開口２０を閉鎖する方向に付勢力が働く。
【００１６】
又、金属外装養生管の施工用に、図３に示すようなブラケット２４を用いる。このブラケット２４は長方形状板体を腕部２５にし、その一端に取付部２６を設け、他端に巻付部２７を設ける。そして、取付部２６には長方形状板体を用いて、腕部２５とＴ字状に結合させ、その腕部２５でほぼ２等分された取付部２６の両側部に丸穴２８を夫々設ける。又、巻付部２７には中央に丁番２９を設けた板状の円リング３０を用い、その両端に短い長方形状板体を夫々突設して結合部を形成し、そこに丸穴３１を夫々設ける。そして、腕部２５の他端と巻付部２７の一端の結合部とは連続体にし、その腕部側にある半円リングの中央付近に更に丸穴３２を設ける。又、巻付部２７の円リング３０にはその内面中央にリングに沿って合成ゴム等からなる帯状の弾性部材３３を配設する。なお、その弾性部材３３にも丸穴３２に対応する位置に当然穴を開けておく。
【００１７】
施工時、建物、躯体等の外部に水道管を付設する場合、ブラケット２４を必要数用意し、そのブラケット２４で支持する一方の管部材１６ａの支持位置に、図４に示すような丸穴３４を電気ドリルを使用する等して開ける。すると、図５に示すように管部材１６ａと筒状ばね体１９とブラケット２４の巻付部２７とを一体に結合できる。その際、管部材１６ａの金属外装１４の外周にブラケット２４の巻付部２７の腕部側にある基端側の半円リングを巻き付け、その基端側の半円リングの位置と一致する管部材１６ａの収納用凹所１８内の位置に筒状ばね体１９を配置し、結合部材として例えばボルト３５を用い、そのボルト３５を丸穴３２、３４を差し通して筒状ばね体１９の受部２３にねじ込んで結合する。
【００１８】
このようにして、管部材１６ａに必要数のブラケット２４と筒状ばね体１９を備え付けた後、その各ブラケット２４を建物の外壁、躯体等の水道管配置箇所に沿わせて順次配置して取り付ける。その際、各ブラケット２４毎に、その取付部２６の両丸穴２８にねじ３６を嵌めて夫々固定する。すると、その取付部２６を建物の外壁、躯体等の例えば垂直部に固定した時に、腕部２５の主面を水平にし、その腕部２５に続く基端側の半円リングで管部材１６ａを受けて、その管部材１６ａの収納用凹所１８と筒状ばね体１９の水道管挿入開口２０とを夫々真上に向けることができる。なお、先端側の半円リングは丁番２９を中心として回動自在である。
【００１９】
そこで、その管部材１６ａの収納用凹所１８に水道管６又はヒーター７付き水道管６を収納する。その際、水道管６の一部を収納用凹所１８の内部に備え付けた筒状ばね体１９の開口２０より挿入して、その収納部２１に押し込む。すると、そのばね本体２２により水道管６の一部を両側から挟持してスプリング力を作用させて固定し、良好に支持できる。それ故、管部材１６ａの収納用凹所１８内に水道管６又はヒーター７付き水道管６を固定できるので、施工時に水道管６等の位置ずれが発生せず施工を行い易くなる。しかも、水道管６の一部等を一度筒状ばね体１９に装着して固定しても、両側から加わるスプリング力に抗する力を加えることにより、挿入開口２０を開いて簡単に外すことができる。それ故、水道管６の一部等をワンタッチで筒状ばね体１９に装着脱でき支持位置を簡単に変更できるので、施工を容易に行なえる。なお、ヒーター７は水道管６に巻き付ける等して備え付けた後に、筒状ばね体１９の開口２０に挿入し、或いは水道管６を筒状ばね体１９の開口２０に挿入した後に、その水道管６に巻き付ける等してもよい。
【００２０】
次に、管部材１６ａの上に対となる他の管部材１６ｂを乗せ、両管部材１６の接触面１７同士を合せ、その両合せ目を片面に接着剤を貼付したアルミニウム等の金属テープを用いて塞ぎ、両管部材１６を結合する。すると、管体が形成でき養生管の本体が完成する。そこで、本体の両端部に、図６に示すようなアルミニウム等の金属製エンドキャップ３７を夫々施す。すると、本体両端の切断面をキャップ３７で各々隠して整えた養生管が完成する。なお、３８は水道管６又はヒーター７付き水道管６を通す挿通穴である。
【００２１】
次に、ブラケット２４の巻付部２７の基端側半円リングで支えた養生管上に、その巻付部２７の先端側半円リングを夫々被せる。その後、巻付部２７の両端にある結合部同士を重ね合わせ、両丸穴３１にボルトを差し通し、ナットで締め付けて結合する。すると、ブラケット２４の巻付部２７を、水道管６又はヒーター７付き水道管６を収納した養生管の外周全体に巻き付け、その養生管を水平方向に配置する等して、良好に支持できる。それ故、養生管等による水道管６又はヒーター７付き水道管６に対する施工後の支持状態も良好になる。
【００２２】
このようにして、外装１４に金属体を施し強度を増して養生管の強度を大きくし、その外周にブラケット２４の巻付部２７を巻き付けて施工すると、養生管に水道管６を支えるブラケット設置穴を大きく開ける必要がない。それ故、養生管の断熱作用を損なうことがなく、優れた断熱効果を発揮できる。又、その養生管にブラケット設置穴を大きく開ける必要もないので、施工が容易であり、施工時間を短くできる。又、養生管の外装１４に金属体を施しておくと、長期間経過してもその外装１４が劣化し難く、外観を損なわずに維持できる。
【００２３】
又、このような養生管の外装１４たる金属体に塗装を施してカラー化すると、塗装により外装１４の強度が更に増して外装１４が一層劣化し難くなり、建物の外壁、躯体等の色に一致した色選択が可能になって、建物、躯体等の美観を損うことなく維持できる。又、養生管を廃棄処理する場合には外装１４たる金属体と本体１５たる断熱材との接着箇所を少なくして分離し易くしておくことにより、両者を簡単に分離できる。それ故、外装１４たるアルミニウム等の金属体をリサイクルし、残りの本体１５たる断熱材を廃棄処分すると、廃棄物を少なくすることができる。
【００２４】
上記実施の形態では管部材１６ａの金属外装１４の外周にブラケット２４の巻付部２７の基端側半円リングを巻き付け、その基端側半円リングの位置と一致する管部材１６ａの収納用凹所１８内の位置に筒状ばね体１９を配置して備え付ける場合について説明したが、管部材の収納用凹所内の適宜位置に先に筒状ばね体を備え付けておき、その管部材の金属外装の外周の適宜位置にブラケットの巻付部の基端側半円リングを巻き付けることもできる。
【００２５】
又、上記実施の形態ではブラケット２４の巻付部２７を養生管の外周全体に巻き付ける場合について説明したが、養生管をブラケットにより支持できれば、ブラケットの巻付部を養生管の外周の一部のみに巻き付けて施工してもよい。
【００２６】
又、上記実施の形態ではストレートの水道管を収納するため、養生管がストレートである場合について説明したが、Ｌ字状に屈曲する水道管を収納するには、接触面にＬ字状の収納用凹所を設けた２個の対となるＬ字状管部材を用いて、Ｌ字状養生管を形成する。又、Ｔ字状に結合する水道管を収納するには、接触面にＴ字状の収納用凹所を設けた２個の対となるＴ字状管部材を用いて、Ｔ字状養生管を形成する。
【００２７】
又、上記実施の形態では金属外装１４を施し、接触面１７の中央に水道管６又はヒーター７付き水道管６を収納する収納用凹所１８を一箇所、一端面から他端面まで貫いて設けた断熱材１５からなる管部材１６を２個用いて対にし、その一方の管部材１６ａの収納用凹所１８内に水道管６又はヒーター７付き水道管６の一部を支持する水道管支持具１９を備え付け、施工時に両管部材１６の収納用凹所１８内に水道管６等を収納して、その支持具１９により水道管６の一部等を支持させ、その両接触面１７同士を合せ、結合して丸形管体を形成し、ブラケット２４の巻付部２７をその金属外装養生管の外周に巻き付ける場合について説明したが、金属外装を施し、接触面の中央部に水道管又はヒーター付き水道管を収納する収納用凹所を複数箇所、例えば２箇所夫々一端面から他端面まで貫いて設けた断熱材からなる管部材を２個用いて対にし、一方の管部材の各収納用凹所内に水道管又はヒーター付き水道管の一部を支持する水道管支持具を夫々備え付け、施工時に両管部材の対となる収納用凹所内に水道管又はヒーター付き水道管を夫々収納して、その各支持具により水道管の一部等を夫々支持させ、その両接触面同士を合せ結合して例えば角形管体を形成し、ブラケットの巻付部をその金属外装養生管の外周に巻き付けることもできる。なお、金属外装を施し、接触面の中央部に水道管等の収納用凹所を２箇所設けた断熱材からなる管部材を２個用いて対にし、管体を形成した金属外装養生管は、特に温水用と普通（冷水）用の２本の水道管を収納するのに適する。
【００２８】
【発明の効果】
以上説明した本発明によれば、請求項１記載の発明では養生管を構成する一方の管部材の内外の一致位置にブラケットの巻付部の一部と水道管支持具とを結合部材を用いて一体に結合すると、そのブラケットの取付部を水道管配置箇所の付近に固定することにより、収納用凹所内に水道管支持具を備えた養生管を簡単に施工でき、その養生管にブラケット設置穴を大きく開ける必要もなくなる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a water pipe curing pipe for accommodating a water pipe or a water pipe with a heater to insulate and protect it from air temperature.
[0002]
[Prior art]
Conventionally, a curing pipe has been used in which a water pipe is housed so as not to be affected by the temperature and is insulated and protected. In particular, in cold regions, in order to prevent water pipes placed outside the building from freezing, a heater cord of a nichrome wire is wound around the outer periphery of the pipe, and then a curing pipe is constructed on the outside thereof. In this case, as shown in FIG. 7, the curing tube is made into a two-part split type having substantially the same shape and structure. Each of the pipe members 1 (1a, 1b) has a double structure of a main body 2 and an exterior 3 integrally formed thereon. A heat insulating material provided through the place 5 from one end surface to the other end surface is used, and a plastic sheet is used for the exterior 3. Then, the water pipe 6 or the water pipe 6 with the heater 7 is stored in the storage recess 5 which is a pair of the two pipe members 1 at the time of construction, and the contact surfaces 4 are joined together to form a pipe, and the curing pipe is formed. Can be formed. In order to connect the two pipe members 1, for example, sheet-like connecting projections 8 (8a, 8b) each having an adhesive adhered to the inner surface thereof are provided at both ends of the contact surface 4 of one of the tube members 1b, for example.
[0003]
When such a curing pipe is installed on a water pipe by a general installation method, a metal bracket 11 provided with an attachment portion 9 at one end and a winding portion 10 at the other end is used. Then, first, for each bracket 11, the mounting portion 9 of the bracket 11 is fixedly mounted on an outer wall, a skeleton, or the like of a building near a water pipe arrangement location. Next, the winding part 10 of the bracket 11 is wound around the outer periphery of the water pipe 6 once, and the water pipe 6 is supported by the bracket 11. Thereafter, a step of performing the curing pipe on the water pipe 6 or winding the heater 7 around the water pipe 6 and then performing the construction of the curing pipe is performed. Therefore, at least one of the tube members 1 constituting the curing tube, for example, the tube member 1a must be partially cut out to form a bracket installation hole 13 through which the arm portion 12 of the bracket 11 passes.

Therefore, the heat insulating effect by the construction of the curing pipe is easily damaged. In addition, the curing pipe construction becomes complicated, and the construction time tends to be long. Moreover, if a plastic sheet is applied as the exterior 3 of the curing pipe, the exterior 3 is liable to deteriorate in a short period of time, a hole is opened in the exterior 3, and the inside heat insulating material 2 is exposed and the exterior 3 is exposed. Gets worse.

Therefore, according to the patent application filed on December 26, 2002, the present applicant has provided a metal exterior and provided a storage recess for storing a water pipe or a water pipe with a heater in the center of the contact surface from one end to the other end. A pair of two pipe members made of heat-insulating material is used as a pair, and a water pipe or a water pipe with a heater is stored in a storage recess that is a pair of both pipe members at the time of construction, and the two contact surfaces are joined together. Using a metal exterior curing pipe for a water pipe that is connected to form a pipe body, and a bracket provided with a mounting part at one end and a wrapped part at the other end, and the mounting part of the bracket is fixed in the vicinity of the water pipe arrangement location And a method for constructing a metal exterior curing pipe for a water pipe in which the wound portion is wound around at least a part of the outer periphery of a metal exterior curing pipe containing a water pipe or a water pipe with a heater.
[0006]
Then, according to the method of installing the metal exterior curing pipe, first, a plurality of brackets are attached along the water pipe arrangement location. Next, one of the tube members is put in a part of the winding part of each bracket, and is supported by the winding part. Then, a water pipe or a water pipe with a heater is stored in the storage recess of the pipe member, and the other pipe member is put in the same part of the winding part of each bracket, and is also supported by the winding part. Finally, the contact surfaces of the two pipe members are joined together, and the joint is closed with a metal tape such as aluminum having an adhesive stuck to one surface. Then, a tube body can be formed and the main body of the curing tube is completed. Then, the curing tube is fixed by putting the other portions of the winding portion on the curing tube supported by a part of the winding portion of the bracket. Therefore, the curing tube can be favorably supported by the plurality of brackets.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a construction process of a metal exterior curing pipe for a straight water pipe to which the present invention is applied, and FIG. 2 is a housing for accommodating a water pipe of one of the pipe members constituting the metal exterior curing pipe or a water pipe with a heater. FIG. 3 is a perspective view showing a water pipe support provided in the recess, and FIG. 3 is a perspective view showing a bracket used for constructing the metal exterior curing pipe. The metal exterior curing pipe for a straight water pipe is a two-part pipe having a double structure composed of a main body 15 provided with an exterior 14 as shown in FIG. In addition, a metal body such as aluminum or stainless steel, for example, a semi-cylindrical body having a thickness of about 0.1 to 0.2 mm is used for the exterior 14 of each pipe member 16 (16a, 16b) in order to increase strength. At that time, if a semi-cylindrical body made of aluminum is used, it is relatively soft, so that processing such as cutting is easy and convenient.
[0014]

[0018]
After the necessary number of brackets 24 and the tubular spring bodies 19 are provided on the pipe member 16a in this manner, the brackets 24 are sequentially arranged and attached along the water pipe arrangement locations such as the outer wall of the building and the skeleton. . At this time, a screw 36 is fitted into each round hole 28 of the mounting portion 26 of each bracket 24 and fixed. Then, when the mounting portion 26 is fixed to, for example, a vertical portion of an outer wall of a building, a skeleton, or the like, the main surface of the arm portion 25 is made horizontal, and the pipe member 16a is connected to the semicircular ring on the base end side following the arm portion 25. As a result, the storage recess 18 of the pipe member 16a and the water pipe insertion opening 20 of the tubular spring body 19 can be directed right above, respectively. In addition, the semicircular ring on the tip side is rotatable around the hinge 29.
[0019]
Then, the water pipe 6 or the water pipe 6 with the heater 7 is stored in the storage recess 18 of the pipe member 16a. At this time, a part of the water pipe 6 is inserted through the opening 20 of the cylindrical spring body 19 provided inside the storage recess 18 and pushed into the storage portion 21. Then, a part of the water pipe 6 is sandwiched from both sides by the spring body 22 and fixed by applying a spring force to the water pipe 6 and can be favorably supported. Therefore, since the water pipe 6 or the water pipe 6 with the heater 7 can be fixed in the storage recess 18 of the pipe member 16a, the water pipe 6 and the like are not displaced at the time of construction, thereby facilitating the construction. Moreover, even if a part of the water pipe 6 is once mounted on the tubular spring body 19 and fixed, the insertion opening 20 can be easily opened and removed by applying a force against the spring force applied from both sides. it can. Therefore, a part of the water pipe 6 and the like can be attached to and detached from the tubular spring body 19 with one touch, and the supporting position can be easily changed, so that the construction can be easily performed. After the heater 7 is provided by being wound around the water pipe 6 or the like, the heater 7 is inserted into the opening 20 of the tubular spring body 19, or after the water pipe 6 is inserted into the opening 20 of the tubular spring body 19, 6 may be wound.
[0020]
Next, another pair of tube members 16b is placed on the tube member 16a, the contact surfaces 17 of the two tube members 16 are joined together, and a metal tape made of aluminum or the like having both joints bonded to one side with an adhesive is applied. And the both pipe members 16 are connected. Then, a tubular body can be formed and the main body of the curing tube is completed. Therefore, metal end caps 37 made of aluminum or the like as shown in FIG. 6 are respectively applied to both ends of the main body. Then, the curing pipes in which the cut surfaces at both ends of the main body are hidden by the caps 37 and completed are completed. Reference numeral 38 denotes an insertion hole through which the water pipe 6 or the water pipe 6 with the heater 7 passes.
[0021]
Next, the distal end side semi-circular rings of the winding portion 27 are put on the curing tubes supported by the base side semi-circular ring of the winding portion 27 of the bracket 24, respectively. Thereafter, the joining portions at both ends of the winding portion 27 are overlapped, bolts are inserted into the round holes 31, and the nuts are joined by fastening with nuts. Then, the winding part 27 of the bracket 24 is wrapped around the entire outer periphery of the curing pipe in which the water pipe 6 or the water pipe 6 with the heater 7 is stored, and the curing pipe can be arranged in a horizontal direction, and thus can be favorably supported. Therefore, the supporting state of the water pipe 6 or the water pipe 6 with the heater 7 by the curing pipe or the like after the construction is improved.
[0022]
In this manner, when the metal body is applied to the exterior 14 and the strength is increased to increase the strength of the curing pipe, and the winding portion 27 of the bracket 24 is wound around the outer periphery of the pipe, the bracket is installed on the curing pipe to support the water pipe 6. There is no need to make large holes. Therefore, an excellent heat insulating effect can be exhibited without impairing the heat insulating effect of the curing pipe. Also, since it is not necessary to make a large bracket installation hole in the curing pipe, the construction is easy and the construction time can be shortened. Further, if a metal body is applied to the exterior 14 of the curing tube, the exterior 14 is hardly deteriorated even after a long period of time, and can be maintained without deteriorating the external appearance.
[0023]
In addition, when a color is applied to the metal body which is the exterior 14 of such a curing pipe by painting, the strength of the exterior 14 is further increased by the coating, and the exterior 14 is hardly deteriorated. Matching color selection becomes possible, and it is possible to maintain the appearance of buildings, frames, and the like without impairing them. When the curing tube is discarded, the metal body serving as the exterior 14 and the heat insulating material serving as the main body 15 can be easily separated from each other by reducing the number of adhesion points and facilitating separation. Therefore, when the metal body such as aluminum as the exterior 14 is recycled and the remaining heat insulating material as the main body 15 is discarded, the amount of waste can be reduced.
