Description

本発明は、複数の真空断熱パネルを断熱対象面に沿わせて互いに隣り合うように並設してある断熱構造に関する。   The present invention relates to a heat insulating structure in which a plurality of vacuum heat insulating panels are arranged side by side so as to be adjacent to each other along a surface to be insulated.
上記断熱構造は、例えば、天然ガスやエチレン,プロピレン,プロパン,アンモニア,炭酸ガス,ブタジエン,ブタン等の液化温度が常温よりも低いガス体を液化状態で貯蔵する容器の側壁外面や二重殻外槽の内面若しくは二重殻内槽の外面などの断熱対象面を断熱するために設けられており、熱伝導率が硬質ポリウレタンフォームの1/5程度という真空断熱パネル(例えば、特開2000−355617号公報参照)を並設してあるので、断熱厚さを薄くできる利点がある。
従来の上記断熱構造では、隣り合う真空断熱パネルどうしの目地部を通した熱の出入りを防止するために、熱伝導率が真空断熱パネルよりも大きい硬質ウレタンフォームなどの発泡断熱材を、現場発泡などの施工方法で、目地部に充填して断熱している(慣用技術であり、先行技術文献情報を開示できない)。
The above heat insulating structure is, for example, the outer surface of the side wall of the container or the outer shell of the double shell for storing a gas body having a liquefaction temperature lower than room temperature such as natural gas, ethylene, propylene, propane, ammonia, carbon dioxide gas, butadiene, butane, etc. It is provided to insulate a heat insulation target surface such as the inner surface of the tank or the outer surface of the double-shell inner tank, and has a heat conductivity of about 1/5 that of rigid polyurethane foam (for example, JP 2000-355617 A). No. 2) are arranged side by side, so that there is an advantage that the heat insulation thickness can be reduced.
In the above conventional heat insulation structure, in order to prevent heat from entering and exiting through joints between adjacent vacuum insulation panels, foam insulation such as rigid urethane foam with higher thermal conductivity than vacuum insulation panels is used in-situ foaming. In the construction method, etc., the joints are filled and insulated (this is a conventional technique and information on prior art documents cannot be disclosed).

本発明は上記実情に鑑みてなされたものであって、断熱構造を大型化することなく、断熱対象面の全面に亘って略均一な断熱性能を確保できるようにすることを目的とする。
For this reason, in order to ensure a substantially uniform heat insulation performance over the entire surface to be insulated, the joint is foamed with a large thickness so that the thermal conductivity in the joint is equivalent to the thermal conductivity of the vacuum thermal insulation panel. It is necessary to cover with a heat insulating material, and there is a drawback that the heat insulating structure is enlarged.
This invention is made | formed in view of the said situation, Comprising: It aims at ensuring substantially uniform heat insulation performance over the whole surface of a heat insulation object surface, without enlarging a heat insulation structure.

Adjacent to each other, joints are provided between adjacent vacuum insulation panels, and the foamed resin insulation is placed inside the outer periphery of the vacuum insulation panel so that the outer periphery of the foam resin insulation wherein the heat insulating target surface side of the vacuum insulation panel is fixed at the opposite surface, an auxiliary vacuum insulation panel, along the joint portion, so as to extend on both sides in the width direction of the joint portion, and In the point which is provided between the outer peripheral parts of the said foamed resin heat insulating materials which adjoin .
