【発明の属する技術分野】
本発明は、貯留設備の断熱構造とその断熱パネルに関し、より詳しくは、硬質の断熱パネル本体が、その断熱パネル本体の裏面側に設けられた永久磁石によって貯留設備の外面に吸着されている貯留設備の断熱構造と、硬質の断熱パネル本体が、その断熱パネル本体の裏面側に設けられた永久磁石によって貯留設備の外面に吸着可能に構成されている貯留設備用の断熱パネルに関する。
【０００２】
【従来の技術】
例えば、重油を貯蔵するタンクでは、重油の粘度上昇を抑制するため、タンク内の重油を適温に温める必要があり、その保温のためにも、タンクの周壁や天井壁には、断熱パネルを取り付ける必要がある。また、重油以外の各種の液体や気体を貯蔵するタンクなどの貯留設備においても、外気などの影響を抑制するために断熱パネルを取り付ける必要がある。
通常、タンクなどの貯留設備では、点検やメンテナンス時に、作業員が断熱パネル上を歩くことがあるため、ある程度の耐荷重性を備えた硬質の断熱パネルが使用され、しかも、その断熱パネルは、点検やメンテナンスに備えて容易に剥がしたり、再度取り付けたりできる構成が望ましい。
そのような要望を満たすものとして、硬質の断熱パネル本体の裏面側に永久磁石などを直接的に取り付け、その永久磁石の磁力によって断熱パネル本体を貯留設備に保持させるように構成したものが提案された（例えば、特開２００２−１０４５８１号公報参照）。
【０００３】
【発明が解決しようとする課題】
ところが、上述した従来構造では、ほとんど湾曲しにくいような硬質の断熱パネルに対して、永久磁石などが直接的に取り付けられているので、貯留設備の周壁や天井壁に凹凸があると、例えば、断熱パネルに取り付けた複数の永久磁石のうち、一部の永久磁石が周壁や天井壁に吸着されるだけで、残りの永久磁石は周壁や天井壁に吸着されない事態が発生する。
事実、貯留設備の外面には、かなりの凹凸が存在し、特に、多数の鋼板を溶接により接続して構成したタンクなどでは、鋼板の端部どうしを互いに重ねて溶接するために多数の凹凸が存在し、従来の構造では、使用する永久磁石の磁力に応じた適切な吸着力を得難いという問題があった。
【０００４】
本発明は、このような従来の問題点に着目したもので、その目的は、断熱パネル本体が湾曲し難い硬質のパネルであって、しかも、貯留設備の外面に凹凸があっても、永久磁石を使用して、極力、その磁力に応じた適切な吸着力で断熱パネルを保持することのできる貯留設備の断熱構造とそのための断熱パネルを提供することにある。

【００２３】
【発明の実施の形態】
本発明による貯留設備の断熱構造とその断熱パネルにつき、その実施の形態を図面に基づいて説明する。
本発明の断熱構造や断熱パネルは、重油貯蔵タンクのような貯留設備を対象とするもので、図１に示すように、重油貯蔵タンク１であれば、直径が４０ｍ〜６０ｍ程度の円筒状の周壁２と、その周壁２の上部を覆う天井壁３を備え、天井壁３は、いわゆる「浮き天井」構造で、周縁にポンツーン４とシール部材５を備え、貯蔵タンク１内の重油の量に応じて昇降するように構成されている。
その天井壁３は、中心付近に設けられた排水口６に向かって勾配がつけられていて、雨水などが排水口６から排水ホース７を経て貯蔵タンク１外へ排水されるように構成されている。
【００２４】
重油貯蔵タンク１の周壁２と天井壁３は、貯留設備の外面に相当するもので、具体的には、図３などに示すように、厚みが４．５ｍｍ〜６ｍｍ程度の多数の鋼板８を溶接により接続して構成されており、そのため、外面には多数の凹凸が存在する。
それに対して、貯蔵タンク１の周壁２や天井壁３の外側に配設すべき断熱パネル本体９は、珪酸カルシウム、発泡樹脂、無機質混入発泡材などの不燃性または準不燃性で、かつ、非吸水性を有する断熱性材料で形成され、人が踏んでもへこまない程度の耐荷重性を備えた硬質の断熱パネルで構成されている。そして、図２などに示すように、例えば、長さが１８００ｍｍ、幅が９００ｍｍ、厚みが３０ｍｍの長方形に形成され、必要な場合には、防水コート９ａなどで被覆されている。
【００２５】
第１の実施形態では、図２および図３に示すように、断熱パネル本体９と同じ材料で形成された長尺状のスペーサ１０が、断熱パネル本体９の裏面において長方形の長辺に沿って互いに平行になるように５本配設され、かつ、各スペーサ１０において、その両端と中央部とに排水用連通空間１１を有する状態で断熱パネル本体９の裏面に接着により取り付けられている。
そして、その各スペーサ１０には、永久磁石１２と可撓性部材１３を兼用する可撓性磁石としてのゴム磁石１４が、可撓性を維持した状態でそれぞれ接着により取り付けられている。つまり、ゴム磁石１４は帯状に形成され、図３の（イ）に示すように、その幅方向の中央部のみが、接着材によってスペーサ１０に接着されていて、幅方向の両端部は、可撓性を維持するために非接着状態とされている。
【００２６】
第１の実施形態による断熱パネルを使用して、重油貯蔵タンク１の周壁２と天井壁３を断熱構造とするには、断熱パネル本体９のゴム磁石１４側の面を周壁２や天井壁３側に向けて押し付ける。
その際、図３に示すように、周壁２や天井壁３に鋼板８の溶接による凹凸があれば、その凸部を中心として断熱パネル本体９を前後左右などに適宜揺動させて押し付ける。すると、ゴム磁石１４の幅方向両端部がスペーサ１０に対して非接着状態で、ゴム磁石１４による磁着部が断熱パネル本体９の裏面に対し遠近方向に移動自在であるため、たとえ凹凸があっても、図３の（ロ）に示すように、ゴム磁石１４の幅方向両端部が、周壁２や天井壁３に対して確実に吸着して断熱パネル本体９を確実に保持することになる。
【００２７】
このような作業を順次繰り返して、周壁２や天井壁３の全面に多数の断熱パネル本体９を取り付けるのであり、周壁２や天井壁３の端部においては、長方形の断熱パネル本体９を端部形状にあわせて切断するか、あるいは、予め端部用の断熱パネル本体９を準備しておいて取り付けるのである。
そして、断熱パネル本体９を取り付けた状態では、スペーサ１０の介在によって、断熱パネル本体９の裏面と周壁２や天井壁３との間には、細長い多数の排水用空間１５が形成され、さらに、各排水用空間１５は、排水用連通空間１１により互いに連通されることになるので、これら空間１１，１５を通して雨水などを確実に排水することができる。
なお、この第１の実施形態による断熱パネルを使用して、重油貯蔵タンク１の周壁２や天井壁３への取り付け強度を確認したところ、建築基準法に準ずる風荷重（６０ｍ／ｓ）にも十分に耐え得ることが判明した。
【００２８】
つぎに、第２〜第４の実施形態について説明するが、重複説明を避けるため、先の実施形態で説明した構成や同じ作用を有する構成については、同じ符号を付すことで説明を省略し、主として先の実施形態と異なる構成についてのみ説明する。
【００２９】
第２の実施形態では、図４および図５に示すように、スペーサ１０が、先の実施形態のような長尺状ではなく、比較的小さなブロック状に形成されて、そのブロック状のスペーサ１０が、断熱パネル本体９の裏面に一定間隔置きに多数配設されて接着されている。
そして、そのブロック状のスペーサ１０には、例えば、可撓性を備え、かつ、適度な剛性を備えた合成樹脂や繊維などからなる十字状の可撓性部材１３が、図５の（イ）に示すように、その中心部分のみ接着により取り付けられていて、十字状可撓性部材１３の４つの先端部分に永久磁石１２が取り付けられ、必要によっては、十字状可撓性部材１３の中心部分にも永久磁石１２が取り付けられている。
【００３０】
第２の実施形態による断熱パネルによれば、可撓性部材１３の介在によって、その可撓性部材１３の先端部分に取り付けられた４つの永久磁石１２の磁着部が、断熱パネル本体９の裏面に対し遠近方向に移動自在となるため、図５に示すように、周壁２や天井壁３に鋼板８の溶接による凹凸があっても、図５の（ロ）に示すように、可撓性部材１３の先端部分に位置する４つの永久磁石１２が、周壁２や天井壁３に対して確実に吸着して断熱パネル本体９を確実に保持することになる。
そして、周壁２や天井壁３の全面に断熱パネル本体９を取り付けた状態では、多数のブロック状スペーサ１０の介在によって、断熱パネル本体９の裏面と周壁２や天井壁３との間には、網目状の排水用空間１５が形成されるので、雨水などを確実に排水することができる。
【００３１】
なお、この第２の実施形態では、可撓性部材１３を十字状にした例を示したが、可撓性部材１３の形状については種々の変更が可能である。
例えば、可撓性部材１３を円形や矩形などの各種形状にして、その中心部分のみをスペーサ１０に取り付け、その周囲に複数の永久磁石１２を取り付けて実施することもできる。
また、この第２の実施形態において、可撓性部材１３と永久磁石１２に代えて、第１の実施形態で説明したゴム磁石１４を使用して、そのゴム磁石１４を十字状、円形、あるいは、矩形などの各種形状にし、その中心部分のみをスペーサ１０に取り付けて実施することもできる。
【００３２】
第３の実施形態では、図６に示すように、ゴムや合成樹脂などのような軟らかくて弾性変形自在で、更に好ましくは、不燃性または準不燃性で、かつ、非吸水性を有する材料からなるブロック状の弾性部材１６が、断熱パネル本体９の裏面に一定間隔置きに多数配設されて接着されて、各ブロック状の弾性部材１６に永久磁石１２が取り付けられている。
【００３３】
第３の実施形態による断熱パネルによれば、弾性変形自在な弾性部材１６の介在によって、永久磁石１２の磁着部が、断熱パネル本体９の裏面に対し遠近方向に移動自在となり、周壁２や天井壁３に鋼板８の溶接による凹凸がある場合、その凸部を中心として断熱パネル本体９を前後左右などに適宜揺動させて押し付けることにより、各弾性部材１６に取り付けられた永久磁石１２が、周壁２や天井壁３に対して確実に吸着して断熱パネル本体９を確実に保持することになる。
そして、断熱パネル本体９を取り付けた状態では、多数のブロック状弾性部材１６が、先の実施形態におけるスペーサ１０の機能も兼用して、断熱パネル本体９の裏面と周壁２や天井壁３との間に網目状の排水用空間１５を形成することになる。
【００３４】
なお、この第３の実施形態では、弾性変形自在な弾性部材１６としてゴムや合成樹脂などからなるブロック状のものを示したが、金属製のコイルスプリングを弾性部材１６として使用することもできる。
【００３５】
第４の実施形態では、図７に示すように、例えば、円形の開口１７ａを有する合成樹脂製の円筒状の筒体１７が、断熱パネル本体９の裏面に一定間隔置きに多数配設されて接着され、各筒体１７には、フランジ１８ａを一体的に有する合成樹脂製の円柱状の移動部材１８が抜き差し自在に収納保持されていて、各移動部材１８の先端部に永久磁石１２が取り付けられている。
【００３６】
第４の実施形態による断熱パネルによれば、筒体１７と移動部材１８の介在によって、永久磁石１２の磁着部が、断熱パネル本体９の裏面に対し遠近方向に移動自在となるため、周壁２や天井壁３に鋼板８の溶接による凹凸があっても、各移動部材１８の先端部に取り付けられた永久磁石１２が、周壁２や天井壁３に対して確実に吸着して断熱パネル本体９を保持し、断熱パネル本体９を取り付けた状態では、多数の筒体１７が、先の実施形態におけるスペーサ１０の機能を兼用して、断熱パネル本体９の裏面と周壁２や天井壁３との間に網目状の排水用空間１５を形成することになる。
【００３７】
なお、この第４の実施形態では、筒体１７を円筒状とし移動部材１８を円柱状に形成した例を示したが、筒体１７を角筒状とし移動部材１８を角柱状とするなど、筒体１７と移動部材１８の形状については種々の変更が可能であり、また、移動部材１８の先端部に永久磁石１２を取り付けるのではなく、移動部材１８そのものを永久磁石１２で形成することもできる。
【００３８】
また、これまでの実施形態では、貯留設備の一例として重油貯蔵タンク１を示し、その周壁２と天井壁３に断熱パネル本体９を取り付けた例を示したが、重油以外の各種液体をはじめとして、各種の気体などを貯留する種々の貯留設備にも適用することができる。
そして、その貯留設備の周壁２や天井壁３などが、例えば、ステンレスのような非磁性体で構成されていても、周壁２や天井壁３の全面あるいは必要箇所に鋼板のような磁性体を貼着し、その磁性体に永久磁石１２やゴム磁石１４を吸着させて断熱パネル本体９を保持させることもでき、したがって、非磁性体からなる貯留設備に対しても適用することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heat insulating structure of a storage facility and a heat insulating panel thereof, and more particularly, to a storage structure in which a hard heat insulating panel body is adsorbed on an outer surface of the storage facility by a permanent magnet provided on a back side of the heat insulating panel body. The present invention relates to a heat insulating structure for equipment and a heat insulating panel for storage equipment in which a hard heat insulating panel main body is configured to be able to be attracted to an outer surface of the storage equipment by a permanent magnet provided on a back side of the heat insulating panel main body.
[0002]
[Prior art]
For example, in a tank that stores heavy oil, it is necessary to heat the heavy oil in the tank to an appropriate temperature in order to suppress the increase in the viscosity of the heavy oil, and to keep that heat, heat insulation panels are attached to the peripheral and ceiling walls of the tank. There is a need. In addition, in a storage facility such as a tank for storing various liquids and gases other than heavy oil, it is necessary to attach a heat insulating panel in order to suppress the influence of outside air and the like.
Normally, in storage facilities such as tanks, workers may walk on the insulation panel during inspection and maintenance, so a hard insulation panel with a certain load resistance is used, and the insulation panel is It is desirable to have a configuration that can be easily peeled off and re-attached for inspection and maintenance.
As a device that satisfies such demands, a device has been proposed in which a permanent magnet or the like is directly attached to the back side of a hard heat insulating panel main body, and the heat insulating panel main body is held in a storage facility by the magnetic force of the permanent magnet. (See, for example, JP-A-2002-104581).
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional structure, a permanent magnet or the like is directly attached to a hard heat-insulating panel that is unlikely to be curved. Of the plurality of permanent magnets attached to the heat insulating panel, only a part of the permanent magnets is attracted to the peripheral wall or the ceiling wall, and the remaining permanent magnets are not attracted to the peripheral wall or the ceiling wall.
In fact, there are considerable irregularities on the outer surface of the storage facility, especially in tanks constructed by connecting a number of steel plates by welding. The existing structure has a problem that it is difficult to obtain an appropriate attraction force according to the magnetic force of the permanent magnet used.
[0004]
The present invention focuses on such a conventional problem, and its object is to provide a permanent panel that is a hard panel whose heat-insulating panel body is unlikely to bend and that has an irregular surface on the outer surface of the storage facility. An object of the present invention is to provide a heat insulating structure of a storage facility capable of holding a heat insulating panel with an appropriate suction force according to its magnetic force as much as possible, and a heat insulating panel therefor.
[0005]
[Means for Solving the Problems]
A feature of the invention according to claim 1 is a heat insulating structure of a storage facility in which a hard heat insulating panel main body is adsorbed on an outer surface of the storage facility by a permanent magnet provided on a back side of the heat insulating panel main body. A magnetically attached portion made of a permanent magnet is movably attached to the back surface of the heat insulating panel body in the near and far directions, and is adsorbed on the outer surface of the storage facility.
[0006]
According to the characteristic configuration of the first aspect of the present invention, since the magnetically attached portion by the permanent magnet is movably attached to the rear surface of the heat insulating panel main body in the near and far directions, the heat insulating panel main body is a hard panel that is hardly curved. Moreover, even if there are irregularities on the outer surface of the storage facility, the permanent magnet magnetized part moves to the near side with respect to the back surface of the heat insulating panel body, so that the permanent magnet magnetized part is securely attached to the outer surface of the storage facility. Adsorbed, the insulation panel body can be held in the storage facility, and as a result, regardless of the presence or absence of irregularities on the outer surface of the storage facility, the insulation panel can be reliably secured with an appropriate suction force according to the magnetic force of the permanent magnet used. It is possible to hold.
[0007]
According to a second aspect of the present invention, in the heat insulating structure of the storage facility described above, the permanent magnet is attached to the heat insulating panel body via a flexible member having flexibility.
[0008]
According to the characteristic configuration of the invention of claim 2, in the above-described heat insulating structure of the storage facility, the permanent magnet is attached to the heat insulating panel main body via a flexible member having flexibility. Even if the outer surface of the equipment has irregularities, the magnetically attached portion of the permanent magnet can be reliably attracted to the outer surface of the storage equipment by effectively utilizing the deformation function of the flexible member.
[0009]
A feature of the invention according to claim 3 is the heat insulating structure of the storage facility described above, wherein the permanent magnet and the flexible member are integrally formed by a flexible magnet.
[0010]
According to the characteristic configuration of the third aspect of the present invention, in the above-described heat insulation structure of the storage facility, the permanent magnet and the flexible member are integrally formed by the flexible magnet. Compared to the case where the flexible member is formed separately, the flexible member is attached to the back surface of the heat insulating panel body, and the permanent magnet is attached to the flexible member, the structure is simplified and the cost is reduced. Is also advantageous.
[0011]
A feature configuration of the invention according to claim 4 is the heat insulation structure of the storage facility described above, wherein the permanent magnet is attached with a spacer interposed between the heat insulation panel main body and the back surface of the heat insulation panel main body. There is a space for drainage between the outside of the equipment.
[0012]
According to the characteristic structure of the invention of claim 4, in the heat insulating structure of the storage facility described above, the permanent magnet is attached with the spacer interposed between the heat insulating panel main body and the back surface of the heat insulating panel main body and the storage facility. Since a drainage space is formed between the outside surface and the outside surface, for example, even if rainwater or the like enters between the heat insulation panel main body and the storage facility outside surface, the wastewater is drained through the drainage space. Deterioration of the heat insulation panel main body and the storage facility due to this is suppressed.
[0013]
According to a fifth aspect of the present invention, in the heat insulation structure of the storage facility described above, the permanent magnet is attached to the heat insulation panel main body via an elastic member that is elastically deformable.
[0014]
According to the characteristic configuration of the invention of claim 5, in the above-described heat insulating structure of the storage facility, the permanent magnet is attached to the heat insulating panel body via the elastic member that is elastically deformable.
