〔産業上の利用分野〕
本考案は、管本体の外周面を断熱材層と保護層
とで被覆すると共に、前記管本体どうしの接続部
を断熱材と外装材で囲繞してある断熱配管に関す
る。[Detailed description of the invention] [Field of industrial application] The present invention covers the outer circumferential surface of the pipe body with a heat insulating material layer and a protective layer, and also covers the joints between the pipe bodies with a heat insulating material and an exterior material. Concerning surrounding insulated piping.
従来の断熱配管においては、管本体どうしの各
接続端部に外嵌する接続部材を設け、両管本体を
接続部材を介して連通接続して接続部を形成して
いた（例えば特開昭55−109882号公報）。
In conventional insulated piping, a connecting member is provided that fits over each connecting end of the pipe bodies, and both pipe bodies are connected via the connecting member to form a connecting part (for example, Japanese Patent Laid-Open No. 55 -109882).
しかし、配管に際し、接続部材を両管本体の各
接続端部に、夫々外嵌接続させなければならない
ために、組付けに手間が多くかかるだけでなく、
管本体の他に接続部材を別途製作しなければなら
ないために、部材点数が多くなりコスト高になる
虞があつた。
However, when piping, the connecting members must be fitted onto each connecting end of both pipe bodies, which not only requires a lot of effort to assemble, but also requires a lot of effort.
Since the connecting member must be manufactured separately in addition to the pipe body, there is a risk that the number of parts will increase and the cost will increase.
本考案は、上記実情に鑑みてなされたものであ
つて、断熱配管を少ない部材で簡単に組付けるこ
とができるとともに、接続部におけるシール性を
高くできる断熱配管の継手部の提供を目的とす
る。 The present invention has been made in view of the above circumstances, and aims to provide a joint part for insulated piping that can be easily assembled with a small number of materials and that can improve the sealing performance at the connection part. .
本考案にかかる断熱配管の継手部は、上記目的
を達成するために、冒記構造のものにおいて、一
方の前記管本体の端部に一体連設した雄嵌合部分
と、他方の前記管本体の端部に一体連設した雌嵌

前記管本体用の前記断熱材層とは各別に形成して
取付けてあることを特徴構成とする。
In order to achieve the above object, the joint part of the insulated piping according to the present invention has the above-mentioned structure, and has a male fitting part integrally connected to the end of one of the pipe bodies, and the other pipe body. The connecting portion is formed by directly fitting a female fitting portion integrally connected to the end of the tube, and a sealing elastic tube extending between the female fitting portion and the male fitting portion is attached to the outer side of both tube bodies. The pipe is characterized in that the heat insulating material for the connecting portion is formed and attached separately from the heat insulating material layer for the pipe body, while being closely attached to the entire circumference.
かかる特徴構成による作用・効果は次の通りで
ある。 The functions and effects of this characteristic configuration are as follows.
すなわち、配管に際して管同士を接続するに
は、一方の管本体の雄嵌合部分と、他方の管本体
の雌嵌合部分を直接嵌合させるだけの簡単な作業
で良く、管本体の他に別部材として接続部材を用
いなくても良い。
In other words, in order to connect pipes during piping, it is enough to simply connect the male fitting part of one pipe body to the female fitting part of the other pipe body, and it is enough to connect the pipes together in addition to the pipe body. It is not necessary to use a connecting member as a separate member.
その上、雄嵌合部分と雌嵌合部分とが嵌合し合
う接続部は、両管本体どうしにわたるシール用弾
性チユーブを両管本体の外側全周に密着させてあ
るから、例えば、特公昭59−26839号公報や実開
昭52−16677号公報に開示されたもののように、
断熱材層にシール部材を付設した構造と比べる
と、管本体どうしの接続箇所からの洩れを防いで
断熱材層へ洩れた液体が浸潤するような虞れを抑
制できて、シール性を一層高められる。 Moreover, the connecting part where the male fitting part and the female fitting part fit each other has an elastic tube for sealing that extends between the two pipe bodies and is in close contact with the entire outer circumference of both pipe bodies. Like those disclosed in Publication No. 59-26839 and Publication of Utility Model Application No. 52-16677,
Compared to a structure in which a sealing member is attached to the insulation layer, it prevents leakage from the connection points between the pipe bodies, suppresses the risk of leaked liquid infiltrating into the insulation layer, and further improves sealing performance. It will be done.
両管本体どうしの接続部を囲繞する断熱材を管
本体の外周面を被覆する断熱材層とは各別に形成
して取付けているから、両管本体どうしを接続し
てシール用弾性チユーブが所望どおりの装着状態
になるように確認したのちに断熱材を装着するこ
とができて、高いシール材を確保できる。 Since the heat insulating material surrounding the joint between the two pipe bodies is formed and attached separately from the heat insulating material layer covering the outer peripheral surface of the pipe body, it is desirable to connect the two pipe bodies to form an elastic tube for sealing. The insulation material can be installed after confirming that it is installed correctly, and a high sealing material can be ensured.
従つて、少ない部材で簡単な管本体どうしの組
付けによつて断熱配管を行うことができ、材料費
及び施工費を安価にして経済性を高めることがで
きた。
Therefore, insulation piping can be achieved by simply assembling the pipe bodies with a small number of members, and the cost of materials and construction can be reduced to improve economic efficiency.
その上、管本体どうしを、シール用弾性チユー
ブによつてシール性を高めた状態で配管接続でき
るから、断熱配管による流体の輸送を、洩れの心
配なく確実に維持できるようになつた。 Furthermore, since the pipe bodies can be connected to each other with improved sealing properties using the sealing elastic tubes, fluid transport through the insulated pipes can now be reliably maintained without fear of leakage.
