Description

本発明は、配管の自重を支え、かつ配管の熱変位（熱移動）を吸収するように支持するための配管支持装置に関する。   The present invention relates to a pipe support device for supporting the weight of a pipe and supporting the pipe so as to absorb thermal displacement (heat transfer) of the pipe.

化学プラントや原子炉などの生産設備で使用される配管は、天井壁などの固定壁から所定の間隔をおいて配管支持装置で支持され、所望の長さずつ順次継ぎ足して接続される。   Pipes used in production facilities such as chemical plants and nuclear reactors are supported by a pipe support device at a predetermined interval from a fixed wall such as a ceiling wall, and are sequentially connected by a desired length.

特に配管支持装置は、配管の自重に耐えつつ、配管内を流通する流体の温度による配管の熱変位に対処できるものでなければならない。配管支持装置で配管の熱変位を拘束すると、熱変位による反力が配管支持装置自体や配管に働くことになる。   In particular, the pipe support device must be able to cope with the thermal displacement of the pipe due to the temperature of the fluid flowing through the pipe while withstanding the weight of the pipe. When the thermal displacement of the pipe is restrained by the pipe support device, a reaction force due to the thermal displacement acts on the pipe support device itself or the pipe.

そのため、従来の配管支持装置としては、配管の熱変位に追従してこれを吸収するようにしたものや、配管の熱変位を拘束して反力に耐えうるようにしたものがある。   For this reason, conventional pipe support devices include those that follow and absorb the thermal displacement of the pipe, and those that can resist the reaction force by restraining the thermal displacement of the pipe.

例えば、図２に示すような配管の熱変位に追従するタイプの配管支持装置３１では、天井壁３２に固定金具３３を取り付け、その固定金具３３からラグプレート３４を吊り下げ、ラグプレート３４とハンガロッド３５とをピン継手３６で連結し、ハンガロッド３５の先端に取り付けた把持具３７で配管３８を把持している。   For example, in a pipe support device 31 of the type that follows the thermal displacement of a pipe as shown in FIG. 2, a fixing bracket 33 is attached to the ceiling wall 32, a lug plate 34 is suspended from the fixing bracket 33, and the lug plate 34 and hanger rod 35 is connected by a pin joint 36, and a pipe 38 is held by a holding tool 37 attached to the tip of the hanger rod 35.

この配管支持装置３１では、配管３８の熱変位を、ハンガロッド３５を長くしてハンガロッド３５の傾き（ハンガロッド３５を揺動させること）で吸収させていた。   In the pipe support device 31, the thermal displacement of the pipe 38 is absorbed by the inclination of the hanger rod 35 by making the hanger rod 35 longer (swing the hanger rod 35).

なお、この出願の発明に関連する先行技術文献情報としては、次のものがある。   The prior art document information related to the invention of this application includes the following.

特開平１１−２５７５４１号公報JP-A-11-257541 特開２０００−５５２４２号公報JP 2000-55242 A

しかしながら、従来の配管支持装置３１では、配管３８の熱変位が大きい場合や、配管３８の配置上ハンガロッド３５を長くできない場合、ハンガロッド３５の傾きが大きくなり、鉛直方向に配管３８を変位させる力が発生する。   However, in the conventional pipe support device 31, when the thermal displacement of the pipe 38 is large, or when the hanger rod 35 cannot be lengthened due to the arrangement of the pipe 38, the inclination of the hanger rod 35 increases, and the force that displaces the pipe 38 in the vertical direction is increased. appear.

このため、従来の配管支持装置３１では、配管３８が持ち上がったりして配管支持装置３１自体や配管３８に応力が加わりやすく、配管支持装置３１や配管３８が損傷したり、配管支持装置３１や配管３８の寿命が短くなったりするなどの問題がある。   For this reason, in the conventional pipe support device 31, the pipe 38 is lifted and stress is easily applied to the pipe support device 31 itself and the pipe 38, the pipe support device 31 and the pipe 38 are damaged, the pipe support device 31 and the pipe 38 are damaged. There is a problem that the service life of 38 is shortened.

そこで、本発明の目的は、配管の熱変位を拘束せず、熱変位が大きくても熱変位を吸収する配管支持装置を提供することにある。   Accordingly, an object of the present invention is to provide a piping support device that does not restrain the thermal displacement of the piping and absorbs the thermal displacement even when the thermal displacement is large.

Provided between the fixed wall is a pipe support member configured such that one end is fixedly supported by the pipe and the other end is configured to be allowed to travel so as to allow thermal deformation movement of the pipe relative to the fixed wall.

And a lower arm attached to the lower arm, and a damper member attached to the lower arm and buffering the movement of the pipe toward the fixed wall.

以下、本発明の好適な実施形態を添付図面にしたがって説明する。   Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

図１（ａ）は本発明の好適な実施形態を示す配管支持装置の正面側（配管の軸方向）から見た部分横断面図、図１（ｂ）はその１Ｂ−１Ｂ線部分断面図である。   Fig.1 (a) is the fragmentary sectional view seen from the front side (the axial direction of piping) of the piping support apparatus which shows suitable embodiment of this invention, FIG.1 (b) is the 1B-1B line | wire partial sectional view. is there.

図１（ａ）および図１（ｂ）に示すように、本実施形態に係る配管支持装置１は、高温流体（加熱流体）を移送する配管２と天井壁などの固定壁３との間に、一端部が配管２に固定支持され、他端部が固定壁３に対して配管２の少なくとも軸方向に対する熱変形移動を許容させるように走行自在に構成した配管支持部材４を設けたものである。この配管支持装置１は、配管支持部材４と、後述する配管把持具２２とからなる。   As shown in FIG. 1A and FIG. 1B, a pipe support device 1 according to this embodiment is provided between a pipe 2 that transfers a high-temperature fluid (heating fluid) and a fixed wall 3 such as a ceiling wall. The pipe support member 4 is configured such that one end is fixedly supported by the pipe 2 and the other end is configured to be allowed to travel so that the fixed wall 3 allows thermal deformation movement in at least the axial direction of the pipe 2. is there. The pipe support device 1 includes a pipe support member 4 and a pipe gripping tool 22 described later.

配管支持装置１は、固定壁３の壁面に沿った方向（長手方向や斜め方向など）に、所定の間隔をおいて設けられる。高温流体としては、水、水蒸気、液体Ｎａなどがある。配管２はＳＵＳなどの金属で形成される。配管２としては、ボイラ、復水器、蒸気熱交換器などの伝熱管や、原子炉の１次系配管、２次系配管などが挙げられる。   The pipe support device 1 is provided at a predetermined interval in a direction (longitudinal direction, oblique direction, etc.) along the wall surface of the fixed wall 3. Examples of the high temperature fluid include water, water vapor, and liquid Na. The pipe 2 is formed of a metal such as SUS. Examples of the piping 2 include heat transfer tubes such as boilers, condensers, and steam heat exchangers, and primary system piping and secondary system piping of a nuclear reactor.

ここで、熱変形移動を許容させるとは、配管２内を流通する流体の温度やその温度変化、あるいは配管２内に流体を流す場合と流さない場合などにより、配管２が熱膨張・熱収縮することで配管２が熱変位しても、配管支持装置１自体や配管２に応力が加わらないようにさせることをいう。   Here, allowing the heat deformation movement means that the temperature of the fluid flowing through the piping 2 and the temperature change thereof, or the case where the fluid flows in the piping 2 and the case where the fluid does not flow, etc. By doing so, it means that even if the pipe 2 is thermally displaced, stress is not applied to the pipe support device 1 itself or the pipe 2.

より詳細には、配管支持部材４は、固定壁３の下部に設けられて配管２の軸方向に沿って形成された走行軌道５と、その走行軌道５上に走行自在に支持された走行体としてのスライドプレート６と、そのスライドプレート６に基端部が取り付けられ、他端部が配管２に連結される支持アーム７とを主に備えて構成される。本実施形態では、コンクリート壁の表面に設ける固定壁３として鋼製のものを用いた。   More specifically, the pipe support member 4 includes a travel track 5 provided along the axial direction of the pipe 2 provided below the fixed wall 3, and a travel body supported on the travel track 5 so as to freely travel. And a support arm 7 having a base end attached to the slide plate 6 and having the other end connected to the pipe 2. In the present embodiment, a steel wall is used as the fixed wall 3 provided on the surface of the concrete wall.

固定壁３の下面には、走行軌道５が区画形成されると共に、スライドプレート６が収容されるケーシング８が固定金具９により取り付けられる。ケーシング８は、配管２の軸方向が長手方向となるように形成されると共に、その下部中央に配管２の軸方向に沿って開口部１０が形成されて外観がほぼ角形に形成される。   A traveling track 5 is defined on the lower surface of the fixed wall 3, and a casing 8 in which the slide plate 6 is accommodated is attached by a fixing bracket 9. The casing 8 is formed so that the axial direction of the pipe 2 is the longitudinal direction, and an opening 10 is formed in the center of the lower part along the axial direction of the pipe 2 so that the appearance is substantially square.

開口部１０の両側には、スライドプレート６を配管２の軸方向（開口部１０の長手方向）に沿って案内するガイド１１，１１が設けられる。これらガイド１１，１１、ケーシング８の内底面、両側の内側壁により、ケーシング８内に走行軌道５が区画形成される。   On both sides of the opening 10, guides 11 and 11 are provided for guiding the slide plate 6 along the axial direction of the pipe 2 (longitudinal direction of the opening 10). A running track 5 is defined in the casing 8 by the guides 11, 11, the inner bottom surface of the casing 8, and the inner walls on both sides.

スライドプレート６の下面の両側には、ガイド１１，１１をまたいで走行軌道５上にスライドプレート６を走行させるための転動体１２がそれぞれ設けられる。本実施形態では、転動体１２として、球状のコロ１３を配管２の軸方向に沿って複数個（図１（ａ）および図１（ｂ）では３個）並べたものを用いた。   On both sides of the lower surface of the slide plate 6, rolling elements 12 for running the slide plate 6 on the running track 5 across the guides 11, 11 are provided. In the present embodiment, a rolling element 12 in which a plurality of spherical rollers 13 (three in FIG. 1A and FIG. 1B) are arranged along the axial direction of the pipe 2 is used.

両側の転動体１２間の距離Ｌ１は、スライドプレート６を配管２の軸方向と交差する方向（図１（ａ）および図１（ｂ）では左右方向）にスライド可能に設けるため、ガイド１１，１１間の距離Ｌ２よりも長くする。   The distance L1 between the rolling elements 12 on both sides is provided so that the slide plate 6 is slidable in the direction intersecting the axial direction of the pipe 2 (the left and right directions in FIGS. 1A and 1B). 11 is longer than the distance L2.

支持アーム７は、基端部がスライドプレート６の下面中央に吊り下げられて固定される。この支持アーム７は、スライドプレート６に連結固定される上部アームとしてのラグプレート１４と、そのラグプレート１４にピン継手１５により連結され、配管の熱変形移動方向に揺動自在（本実施形態では、配管２の軸方向に揺動自在）に支持させて配管２に取り付けられる下部アームとしてのハンガロッド１６と、そのハンガロッド１６の上部に取り付けられ、配管２の固定壁３側（図１（ａ）および図１（ｂ）では鉛直上方向）への移動を緩衝して吸収するダンパ部材１７とを備える。   The support arm 7 is fixed with its base end suspended from the center of the lower surface of the slide plate 6. The support arm 7 is a lug plate 14 as an upper arm that is connected and fixed to the slide plate 6, and is connected to the lug plate 14 by a pin joint 15, and can swing freely in the direction of heat deformation of the pipe (in this embodiment). The hanger rod 16 as a lower arm that is supported on the pipe 2 by being supported so as to be swingable in the axial direction of the pipe 2 and the upper part of the hanger rod 16 is attached to the fixed wall 3 side of the pipe 2 (FIG. 1A). And a damper member 17 that buffers and absorbs movement in the vertical upward direction in FIG.

ピン継手１５は、ラグプレート１４の下方と両側を覆うＵ字形に形成されたクレビス１８と、これらラグプレート１４とクレビス１８を締結するボルト１９およびナット２０とからなる。ダンパ部材１７は、ケース内に圧縮スプリング２１を収容したスプリングハンガである。ハンガロッド１６の下端部である先端部には、配管２を両側から把持する二つ割りの配管把持具２２が取り付けられて固定される。   The pin joint 15 includes a clevis 18 formed in a U shape covering the lower side and both sides of the lug plate 14, and a bolt 19 and a nut 20 that fasten the lug plate 14 and the clevis 18. The damper member 17 is a spring hanger in which a compression spring 21 is accommodated in a case. A split pipe gripping tool 22 that grips the pipe 2 from both sides is attached to and fixed to the distal end that is the lower end of the hanger rod 16.

ラグプレート１４中心（スライドプレート６）のスライド可能範囲は、図１（ａ）および図１（ｂ）の例では、配管２の軸方向でＸであり、配管２の軸方向と交差する方向でＹである。このスライド可能範囲は、あらかじめ設計段階で、配管系の熱変位解析を行って決定しておく。   The slidable range at the center of the lug plate 14 (slide plate 6) is X in the axial direction of the pipe 2 in the example of FIGS. 1 (a) and 1 (b), and in the direction intersecting with the axial direction of the pipe 2. Y. This slidable range is determined in advance by performing a thermal displacement analysis of the piping system at the design stage.

本実施形態の作用を説明する。   The operation of this embodiment will be described.

配管２内に高温流体を流通させて移送すると、配管２が主に軸方向に熱膨張する（配管２の軸方向に対して斜めの方向にも若干熱膨張する）ことで、伸びて熱変位する。このとき、配管支持装置１では、配管２と固定壁３との間に配管支持部材４を設けているため、転動体１２を有するスライドプレート６がケーシング８内を配管２の軸方向に沿って小さな力でスライドする。すなわち、配管支持装置１は、スライドプレート６が配管２の小さな熱変位にも直ちに追従して走行軌道５上を走行することで、配管２の熱変位を吸収できる。   When a high-temperature fluid is circulated and transferred in the pipe 2, the pipe 2 mainly expands in the axial direction (slightly expands in an oblique direction with respect to the axial direction of the pipe 2), thereby extending and thermal displacement. To do. At this time, in the pipe support device 1, since the pipe support member 4 is provided between the pipe 2 and the fixed wall 3, the slide plate 6 having the rolling elements 12 passes through the casing 8 along the axial direction of the pipe 2. Slide with a small force. That is, the pipe support device 1 can absorb the thermal displacement of the pipe 2 by the slide plate 6 traveling on the travel track 5 immediately following the small thermal displacement of the pipe 2.

配管支持装置１では、スライドプレート６のスライド可能範囲が配管２の軸方向でＸであり、このＸを配管２の熱膨張による最大熱変位と同等以上にしているため、スライドプレート６がスライドすることにより、配管２の通常の熱膨張だけではハンガロッド１６が傾くこともなく、鉛直方向に配管２を熱変位させる力は発生しない。配管２が熱収縮する場合も同様である。   In the pipe support device 1, the slidable range of the slide plate 6 is X in the axial direction of the pipe 2, and since this X is equal to or greater than the maximum thermal displacement due to the thermal expansion of the pipe 2, the slide plate 6 slides. As a result, the hanger rod 16 is not tilted only by the normal thermal expansion of the pipe 2, and no force that causes the pipe 2 to be thermally displaced in the vertical direction is generated. The same applies when the pipe 2 is thermally contracted.

したがって、配管支持装置１によれば、配管２が熱膨張・熱収縮することで配管２が熱変位しても、配管支持部材４により配管支持装置１自体や配管２に応力が加わらないため、配管２の熱変位を拘束せず、熱変位が大きくても熱変位を吸収できる。配管支持装置１は、いわば熱変形を拘束しないハンガ取付金物である。   Therefore, according to the pipe support device 1, even if the pipe 2 is thermally displaced due to thermal expansion / contraction of the pipe 2, no stress is applied to the pipe support device 1 itself or the pipe 2 by the pipe support member 4. The thermal displacement of the pipe 2 is not constrained and can be absorbed even if the thermal displacement is large. The pipe support device 1 is a hanger fitting that does not restrain thermal deformation.

配管支持装置１は、配管支持部材４が、ラグプレート１４に配管２の軸方向に揺動自在に支持されるハンガロッド１６を備えており、何らかの原因で配管２が異常に大きく熱変位し、スライドプレート６のスライド可能範囲が配管２の軸方向でＸを超えたとしても、ハンガロッド１６が傾くので配管２の熱変位を吸収できる。   The pipe support device 1 includes a hanger rod 16 in which a pipe support member 4 is supported on a lug plate 14 so as to be swingable in the axial direction of the pipe 2. Even if the slidable range of the plate 6 exceeds X in the axial direction of the pipe 2, the hanger rod 16 is inclined, so that the thermal displacement of the pipe 2 can be absorbed.

さらに配管支持装置１は、配管支持部材４が配管２の固定壁３側への移動を緩衝するダンパ部材１７を備えているため、配管支持装置１自体や配管２に上下振動が加わっても、配管２の鉛直方向の変位を吸収できる。   Furthermore, since the pipe support device 1 includes the damper member 17 that buffers the movement of the pipe 2 toward the fixed wall 3 side, even if vertical vibration is applied to the pipe support device 1 itself or the pipe 2, The displacement in the vertical direction of the pipe 2 can be absorbed.

高温流体として液体Ｎａを使用する場合は、液体Ｎａが約５００℃にもなることがあり、また配管２としてＳＵＳ製のものを使用する場合には、ＳＵＳ製の配管２が熱により約１００〜２００ｍｍも大きく伸縮することがある。このような場合に配管支持装置１を使用すると、特に有用である。   When liquid Na is used as the high-temperature fluid, the liquid Na may reach about 500 ° C., and when the pipe 2 is made of SUS, the pipe 2 made of SUS is about 100 to 100 ° C. due to heat. It can expand and contract as much as 200 mm. It is particularly useful to use the pipe support device 1 in such a case.

また、配管支持装置１は、主に配管２の直線部に設けられて使用されるが、曲がり部に使用しても同じ作用効果が得られる。   Moreover, although the piping support apparatus 1 is mainly provided and used for the linear part of the piping 2, even if it uses it for a bending part, the same effect is obtained.

上記実施形態では、スライドプレート６を走行させるための転動体１２として球状のコロ１３を用いたが、転動体としては、円柱状や円筒状のコロや、走行軌道５上を走行する車輪を用いてもよい。   In the above embodiment, the spherical roller 13 is used as the rolling element 12 for running the slide plate 6. However, as the rolling element, a columnar or cylindrical roller or a wheel that runs on the running track 5 is used. May be.

ケーシングを角形ではなく丸形に形成し、その丸形のケーシングに合わせてスライドプレートも円盤状に形成すれば、スライドプレートのスライド方向をフリーすることもできる。   If the casing is formed in a round shape instead of a square shape, and the slide plate is also formed in a disc shape in accordance with the round casing, the sliding direction of the slide plate can be freed.

また、上記実施形態では、スライドプレート６の下面に転動体１２を設けた例で説明したが、スライドプレート６の上面に転動体を設ければ、下置き用のハンガロッドにも使用できる。固定壁３を貫通した上面に走行軌道を設けるようにしてもよい。   Moreover, although the said embodiment demonstrated the example which provided the rolling element 12 in the lower surface of the slide plate 6, if a rolling element is provided in the upper surface of the slide plate 6, it can be used also for the hanger rod for installation. A traveling track may be provided on the upper surface penetrating the fixed wall 3.
