Description

【0001】
【発明の属する技術分野】
この発明は、冷媒配管用管支持具に関する。
【0002】
【従来の技術】
従来、冷媒搬送管は、冷媒が周囲雰囲気の熱影響を受けないよう独立発泡層よりなる断熱層を外周に嵌め付け、あるいは断熱シートを巻付けて被覆し断熱することが行われる。
【0003】
ところで、このような冷媒搬送管を配管施工する場合、図7、図8に示すように冷媒搬送管1の断熱層2外周からバンド金具3を巻きつけ、例えば壁面や天井(図示例は壁面)などに固定して配管することが行われる。
【0004】
なお、図8に示す径の細い冷媒搬送管が例えば液化ガス、太い冷媒搬送管が冷却ガスなどとされているが、これら冷媒搬送管には断熱層2が設けられているにもかかわらずこれらを固定するバンド金具3外表面に結露する事が往々にしてあり、この結露水4が滴下して、壁面や床に染み跡をつける問題があった。
【0005】
これは、断熱層2が長期間の内に冷媒搬送管1によって次第に冷やされ、やがて断熱層2の外表面温度も低下し、バンド金具3と共に結露点を超えてしまうのがバンド金具3の表面結露の原因となるからと考えられる。
【0006】
また、バンド金具3で断熱層2を締め付けると、断熱層2が局部的に圧縮変形され、その圧縮変形の程度に応じて断熱効果が失われ、バンド金具3外周表面の結露がひどくなるといった問題もある他、バンド金具3で締め付けた部分が節のようにくびれて管の外観が悪くなるといった問題もある。
一方、取り付け金具の冷媒搬送管1の断熱層2への食い込みを防止し、かつこの取り付け金具へ冷媒搬送管1の熱伝導を無くすため、図9に示すように分厚いリング状の断熱成形体5を冷媒搬送管1の断熱層2上からさらに被せ、この断熱成形体5外面に一つ割りとされた環状金具6を当てがいヒンジ部分7で閉じ、耳片8、8同士を締結金具(図示せず)で締結するといったことも一般に行われている(例えば特許文献1、2)。

【0008】
【特許文献2】
特開2002-286166号公報
【0009】
【発明が解決しようとする課題】
しかしながら、バンド金具3の取付け個所毎に上記した断熱成形体を嵌めつけていくのは、施工の手間がかかる上、断熱成形体の数も多数にわたるので、コストもかかるといった問題がある。
【0010】
さらに、上記の断熱成形体はそれぞれ単数の冷媒搬送管に対応しており、図7に示したように任意に複数の管をまとめてバンド金具で締結するような場合には使用できないといった問題もある。
【0011】
この発明は上記問題を解決し、より簡単なバンド金具で、結露することも無くまた断熱効率も良好に冷媒搬送管を止着することを課題としてなされたものである。
【0012】
【課題を解決するための手段】
上記目的を達成するため、請求項1の発明は、断熱層を外周に設けた冷媒搬送管を構造物に固定する管支持具であって、前記冷媒搬送管外周を囲む金属製板のバンド体内面に、前記断熱層に対する発泡樹脂製のセパレート層が設けられ、このバンド体を連結する連結部材と、該連結部材を前記構造物に取付ける支持部材とからなるものである。
【0013】
従って、断熱層から伝わる熱も、金属板製のバンド体内面にセパレート層を設けるといった簡単な構成により確実に金属板表面まで届きにくくなり、結露が防止される。
【0014】
これは、冷媒搬送管表面から断熱層表面へ向け、断熱層内の温度は厚さに応じて次第に変化していると考えられるが、このようにして断熱層表面に表われた温度が、バンド体側のセパレート層に伝わろうとしても、このセパレート層と断熱層とは、単に接触しているだけで一体的に密着していないので、熱が伝わりにくくなり、一方、外気温によって相対的に暖められているバンド金具表面の熱も前述の接触面で冷媒搬送管側へ伝熱されにくくなり、結局両者この不連続面を境界として互いの方向への伝熱がされにくくなり、この結果、バンド金具表面が外気の結露温度以下に低下し難くなるためと考えられる。
【0015】
また、断熱層とセパレート層との接触面には大気が殆ど無いので結露は生じず、また結露が発生することがあってもこれらは断熱層内に吸収されるか、層間に毛細管現象で滞留するので、滴下するのは防止される。
【0016】
また、複数の管であっても、一つのバンド体でまとめて束ねることができるので、施工も容易となるなどの効果がある。
請求項2の発明は、請求項1における冷媒配管用管支持具において、バンド体内面に設けられるセパレート層がバンド体内面全面に設けられているものである。
【0017】
請求項1の発明では、セパレート層が冷媒搬送管と当接する部分だけとされている場合も含まれるが、このようにバンド体全面に設ければ、どのような配置の管に対しても適用可能となり、設置の制限が無くなって施工が容易となる。
【0018】
請求項3の発明は、請求項1または2における冷媒配管用管支持具において、バンド体内面に設けられる断熱層の表面が凹凸面とされ、該凹凸面によって冷媒搬送管外周の断熱層外周との間に多数の微小隙間が形成されるようにされてなるものである。
【0019】
冷媒搬送管の断熱層と、金属製バンド体内面に形成される断熱層との間に微小な隙間が形成されるので、これらによってさらに層間の断熱が図られ、バンド金具外面の結露がさらに防止される。
【0020】
【実施の形態】
次にこの発明の冷媒配管用管支持具の実施の形態を説明する。
図1は、この発明の実施の形態である冷媒配管用管支持具の正面図、図2は同じく側面図、図3は図1のA-A線断面図、図4はバンド金具の説明斜視図、図5は冷媒配管用管支持具の分解斜視図である。
【0021】
冷媒配管用管支持具10は、断熱層2を外周に設けた液化ガスあるいは冷却ガスなどの冷媒搬送管1の外周を囲んで、図4に示すように容易に湾曲変形可能な金属板製のバンド11の内面に、発泡樹脂製のセパレート層12が設けられ、このバンド体11の端部にはボルト13、13がそれぞれ延長方向へ突出させて溶接され、このバンド体11のボルト13、13を挿通させナット15、15を締結する連結部材14が設けられ、この連結部材14に天井、壁面などに取付る支持部材16が設けられている。
【0022】
上記においてバンド体11内面に設けられるセパレート層12は、発泡ポリエチレンなどよりなる発泡層の表面に塩化ビニル製の皮膜層をラミネートしたものや、皮膜層として細かい凹凸の形成されたシート等が好適に用いられる。また、図示例はバンド体11の全面に設けた場合を示しているが、冷媒搬送管1の断熱層が当接する部分だけ部分的に設ける構成としても良い。
【0023】
そして、これらセパレート層12は、バンド体11内面に対し接着剤や粘着材などで一体的に貼り付けることが望ましい。
また、連結部材14は、短冊状の基板よりなり、図5に示すように中央部に支持部材16の取り付け用ねじ孔が、ナット17を溶接することで設けられ、このねじ孔用ナット17を挟んだ両側に長孔18、18が穿設されている。
【0024】
なお、バンド体11及び連結部材14の形態としては、図6に示すように、バンド体11を一つ割り状のC字状の環状金具とし、連結部材14を環状金具の割り部11aに形成した耳片11b、11bを接続するボルトなどとした構造のものなどとしても良い。
【0025】
次に、冷媒配管用管支持具10の使用状態を説明する。
まず、図7に示したように冷媒搬送管1を配管し壁面などに取り付ける場合、図4に示すようにまず、内面にセパレート層12を貼り付けた金属製バンド11を冷媒搬送管1の外径に沿うようにU字状に湾曲曲折する。
【0026】
そして、図1に示したように束ねられた冷媒搬送管1の断熱層2を圧縮しないように外嵌めし、ボルト13、13にナット15、15をねじ嵌合したあと、連結部材14の長孔18、18に挿通し、金属製バンド11の締め付け必要長さ調整を行った後、再度別のナット15をねじ嵌合し、緊締することによって金属製バンド11を連結部材14に固定する。
【0027】
その後適宜手段で支持部材16を連結部材14に固定し、この支持部材16を壁又は天井などの建物構造物に固定する。
以上で冷媒搬送管の取り付けは終了する。
【0028】
この場合において、冷媒搬送管に冷媒を流通させた場合、管表面から断熱層表面へ向け、断熱層内の温度は外へ行くほど厚さに応じて次第に高温となる。一方、金属製バンド11の表面は外気温によって冷媒搬送管表面よりは高温となっており、この表面から金属製バンド11内面に設けられたセパレート層12内部の熱は冷媒搬送管に近づくほど低下している。
【0029】
この場合、断熱層2とセパレート層12とが本発明と異なり単一層となっている場合は、冷媒搬送管の冷熱が緩慢とは言え次第にバンド11へと伝わり、経時的に外気温より低下して結露するといったことが生じる。
【0030】
しかし、本発明のように断熱層2にセパレート層12を介してバンド11を当接させると、断熱層2、セパレート層12の間は単に接触しているだけとなるから熱伝導が極めて行われにくく、両層間の温度差がそのまま温度段差として維持されていると考えられる。
【0031】
従って、両者の間に熱的な段差があっても、不連続面を境界として互いの方向への伝熱がされにくくなり、この結果、バンド金具表面が外気の結露温度以下に低下し難くなる。
【0032】
断熱層表面に微小凹凸を多数形成した場合は、層間に微小空間が多数出来るので直接接触がそれだけ避けられ、伝熱性がさらに悪くなる。
なお、上記実施の形態として大小二本の冷媒搬送管を取り付ける場合について説明したが、図示は省略するが一本あるいは、三本以上のパイプであっても束にして一まとめに止着する場合も同様にできる。
【0033】
【発明の効果】
以上説明したように、冷媒搬送管の外周に設けた断熱層に対し直接金属製バンドを当接するのではなく、内面にセパレート層を設けた金属製バンドを当接させて冷媒搬送管を支持するため、断熱層とセパレート層間での熱伝達が非常に悪くなり、この結果金属製バンドの表面温度の低下が防げ、バンド表面の結露が防止できるのである。
【0034】
また、金属製バンド内面のセパレート層の厚さが薄くても、断熱層との界面での伝熱が非常に少なくなるので、上記効果はかなり薄い断熱層でも期待でき、実施が容易となる効果を有する。
【0035】
また請求項2のように断熱層表面を凹凸面とし、この凹凸面による微小隙間を断熱層界面に形成させれば、さらに優れた断熱効果が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pipe support for a refrigerant pipe.
[0002]
[Prior art]
Conventionally, in order to prevent the refrigerant from being affected by the heat of the surrounding atmosphere, a heat insulating layer made of an independent foam layer is fitted to the outer periphery of the refrigerant conveying pipe, or a heat insulating sheet is wound around the pipe to cover and heat the refrigerant.
[0003]
By the way, when piping such a refrigerant transport pipe, as shown in FIGS. 7 and 8, a band fitting 3 is wound around the outer circumference of the heat insulating layer 2 of the refrigerant transport pipe 1 and, for example, a wall surface or a ceiling (in the illustrated example, a wall surface). Piping is performed by fixing it to such a place.
[0004]
Although the small-diameter refrigerant transport pipes shown in FIG. 8 are, for example, liquefied gas and the thick refrigerant transport pipes are cooling gas, etc. Dew condensation often occurs on the outer surface of the band fitting 3 for fixing the condensate, and there is a problem that the condensed water 4 drops and stains the wall and floor.
[0005]
This is because the heat insulating layer 2 is gradually cooled by the refrigerant transport pipe 1 over a long period of time, and the outer surface temperature of the heat insulating layer 2 eventually drops, and the surface of the band metal 3 together with the band metal 3 exceeds the dew point. This is considered to be the cause of condensation.
[0006]
Further, when the heat insulating layer 2 is tightened by the band fitting 3, the heat insulating layer 2 is locally compressed and deformed, and the heat insulating effect is lost according to the degree of the compression deformation, and the dew condensation on the outer peripheral surface of the band fitting 3 becomes severe. In addition, there is also a problem that the portion fastened by the band fitting 3 is constricted like a node and the appearance of the tube is deteriorated.
On the other hand, in order to prevent the mounting bracket from biting into the heat insulating layer 2 of the refrigerant transport pipe 1 and to eliminate the heat conduction of the refrigerant transport pipe 1 to this mounting bracket, as shown in FIG. Is further covered from above on the heat insulating layer 2 of the refrigerant conveying pipe 1, and the annular metal piece 6, which has been split, is closed on the outer surface of the heat insulating molded body 5 at the hinge portion 7, and the lugs 8, 8 are fastened to each other with a fastening metal (FIG. (Not shown) is generally performed (for example, Patent Documents 1 and 2).

[Problems to be solved by the invention]
However, fitting the above-described heat-insulating molded body at each mounting position of the band fitting 3 requires a lot of work and requires a large number of heat-insulating molded bodies, and thus has a problem that the cost is high.
[0010]
Furthermore, the above-mentioned heat-insulating molded bodies each correspond to a single refrigerant transport pipe, and as shown in FIG. 7, there is also a problem that it cannot be used when a plurality of pipes are arbitrarily combined and fastened with band fittings. is there.
[0011]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has been made to solve the above-mentioned problem, and to provide a simpler band fitting, which does not cause dew condensation and has good heat insulation efficiency, and which has an object to fasten a refrigerant transport pipe.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a pipe support for fixing a refrigerant transport pipe provided with a heat insulating layer on the outer periphery to a structure, wherein the metal transport band surrounds the refrigerant transport pipe. A separate layer made of a foamed resin for the heat insulating layer is provided on the surface, and comprises a connecting member for connecting the band body and a supporting member for attaching the connecting member to the structure.
[0013]
Therefore, the heat transmitted from the heat insulating layer also does not easily reach the surface of the metal plate with a simple configuration such as providing the separate layer on the inner surface of the band made of the metal plate, thereby preventing dew condensation.
[0014]
It is considered that the temperature in the heat insulating layer gradually changes in accordance with the thickness from the surface of the refrigerant transport pipe to the surface of the heat insulating layer. Even if it tries to transmit to the separate layer on the body side, the separate layer and the heat insulating layer are simply in contact with each other and are not in close contact with each other, so it is difficult for heat to be transmitted, and on the other hand, it is relatively warmed by the outside temperature The heat on the surface of the band metal fitting is also less likely to be transferred to the refrigerant transport pipe side at the contact surface, and eventually, it is difficult for both to transfer heat to each other with the discontinuous surface as a boundary. It is considered that the surface of the metal fitting is less likely to be reduced to a temperature lower than the dew condensation temperature of the outside air.
[0015]
Also, since there is almost no air at the contact surface between the heat insulating layer and the separate layer, dew condensation does not occur, and even if dew condensation occurs, these are absorbed in the heat insulating layer or stay between the layers due to capillary action. Therefore, dripping is prevented.
[0016]
In addition, since a plurality of pipes can be bundled together in a single band body, there is an effect that construction is easy.
According to a second aspect of the present invention, in the pipe support for a refrigerant pipe of the first aspect, the separate layer provided on the inner surface of the band is provided on the entire inner surface of the band.
[0017]
According to the first aspect of the present invention, the case where the separate layer is only a portion in contact with the refrigerant transport pipe is included, but if the separate layer is provided on the entire surface of the band body as described above, the present invention can be applied to any arrangement of pipes. It becomes possible, and there is no restriction on installation, and construction becomes easy.
[0018]
According to a third aspect of the present invention, in the pipe support for a refrigerant pipe according to the first or second aspect, the surface of the heat insulating layer provided on the inner surface of the band has an uneven surface, and the uneven surface and the outer periphery of the heat insulating layer on the outer periphery of the refrigerant transport pipe. A large number of minute gaps are formed between them.
[0019]
Since a small gap is formed between the heat insulating layer of the refrigerant transport pipe and the heat insulating layer formed on the inner surface of the metal band, heat insulation between the layers is further achieved by these, and dew condensation on the outer surface of the band fitting is further prevented. Is done.
[0020]
Embodiment
Next, an embodiment of a pipe support for refrigerant pipes of the present invention will be described.
FIG. 1 is a front view of a refrigerant pipe support according to an embodiment of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a sectional view taken along line AA of FIG. 1, and FIG. FIG. 5 and FIG. 5 are exploded perspective views of the refrigerant pipe support.
[0021]
As shown in FIG. 4, the refrigerant pipe support 10 surrounds the outer periphery of the refrigerant transfer pipe 1 such as a liquefied gas or a cooling gas provided with the heat insulating layer 2 on the outer periphery. A separate layer 12 made of a foamed resin is provided on the inner surface of the band 11, and bolts 13, 13 are welded to the ends of the band body 11 so as to protrude in the extending direction, respectively. Is provided, and a connecting member 14 for fastening the nuts 15, 15 is provided. The connecting member 14 is provided with a support member 16 to be attached to a ceiling, a wall surface or the like.
[0022]
In the above, the separate layer 12 provided on the inner surface of the band body 11 is preferably formed by laminating a vinyl chloride film layer on the surface of a foam layer made of foamed polyethylene or the like, or a sheet having fine irregularities formed as the film layer. Used. Further, although the illustrated example shows a case in which the heat insulating layer is provided on the entire surface of the band body 11, a configuration in which the heat insulating layer of the refrigerant transport pipe 1 is provided partially only in contact with the heat insulating layer may be employed.
[0023]
It is desirable that these separate layers 12 be integrally attached to the inner surface of the band body 11 with an adhesive or an adhesive.
The connecting member 14 is formed of a strip-shaped substrate. As shown in FIG. 5, a screw hole for mounting the support member 16 is provided at the center by welding a nut 17. Elongated holes 18, 18 are formed on both sides of the sandwich.
[0024]
As shown in FIG. 6, the form of the band body 11 and the connecting member 14 is such that the band body 11 is a one-piece C-shaped annular metal fitting, and the connecting member 14 is formed on the split part 11a of the annular metal fitting. The lug 11b may have a structure such as a bolt for connecting the lug 11b.
[0025]
Next, a usage state of the refrigerant pipe support 10 will be described.
First, as shown in FIG. 7, when the refrigerant transport pipe 1 is piped and attached to a wall surface or the like, first, as shown in FIG. 4, a metal band 11 having an inner surface to which a separate layer 12 is attached is attached to the outside of the refrigerant transport pipe 1. It is bent and bent into a U-shape along the diameter.
[0026]
Then, as shown in FIG. 1, the heat insulating layer 2 of the bundled refrigerant transport pipes 1 is externally fitted so as not to be compressed, and nuts 15, 15 are screw-fitted to the bolts 13, 13. After passing through the holes 18 and 18 and adjusting the required length of tightening the metal band 11, another nut 15 is screwed and tightened again to fix the metal band 11 to the connecting member 14.
[0027]
Thereafter, the supporting member 16 is fixed to the connecting member 14 by appropriate means, and the supporting member 16 is fixed to a building structure such as a wall or a ceiling.
Thus, the mounting of the refrigerant transport pipe is completed.
[0028]
In this case, when the refrigerant is circulated through the refrigerant transfer pipe, the temperature in the heat insulating layer gradually increases from the pipe surface to the heat insulating layer surface according to the thickness as going outward. On the other hand, the surface of the metal band 11 has a higher temperature than the surface of the refrigerant transport tube due to the outside air temperature, and the heat inside the separate layer 12 provided on the inner surface of the metal band 11 from this surface decreases as it approaches the refrigerant transport tube. are doing.
[0029]
In this case, when the heat insulating layer 2 and the separate layer 12 are a single layer unlike the present invention, the cooling heat of the refrigerant transport pipe is gradually transmitted to the band 11 even though it is slow, and the temperature becomes lower than the outside temperature with time. Condensation may occur.
[0030]
However, when the band 11 is brought into contact with the heat insulating layer 2 via the separate layer 12 as in the present invention, heat conduction is extremely performed because the heat insulating layer 2 and the separate layer 12 are merely in contact with each other. Therefore, it is considered that the temperature difference between the two layers is maintained as a temperature step.
[0031]
Therefore, even if there is a thermal step between the two, it is difficult for heat to be transferred to each other with the discontinuous surface as a boundary, and as a result, the surface of the band fitting is less likely to fall below the dew condensation temperature of the outside air. .
[0032]
When a large number of minute irregularities are formed on the surface of the heat insulating layer, a large number of minute spaces can be formed between the layers, so that direct contact can be avoided accordingly, and the heat conductivity is further deteriorated.
In addition, although the case where two large and small refrigerant conveyance pipes are attached has been described as the above-described embodiment, the illustration is omitted, but one or three or more pipes are bundled together and fixed together. Can be done similarly.
[0033]
【The invention's effect】
As described above, instead of directly abutting the metal band to the heat insulating layer provided on the outer periphery of the refrigerant transport tube, the metal band provided with the separate layer on the inner surface is abutted to support the refrigerant transport tube. Therefore, heat transfer between the heat insulating layer and the separate layer becomes extremely poor, and as a result, a decrease in the surface temperature of the metal band can be prevented, and dew condensation on the band surface can be prevented.
[0034]
In addition, even if the thickness of the separate layer on the inner surface of the metal band is small, the heat transfer at the interface with the heat insulating layer is very small. Having.
[0035]
Further, when the surface of the heat insulating layer is formed as an uneven surface and minute gaps formed by the uneven surface are formed at the interface of the heat insulating layer, a further excellent heat insulating effect can be obtained.
