Description

本発明は、筒状の被断熱面に、周方向に沿って複数の断熱パネルを隣り合う断熱パネルの周方向端面どうしが対向するように取り付けて、前記被断熱面を断熱可能に構成してある断熱装置に関する。   The present invention is configured such that a plurality of heat insulating panels are attached to a cylindrical heat insulating surface along the circumferential direction so that circumferential end surfaces of adjacent heat insulating panels face each other, and the heat insulating surface can be insulated. It relates to an insulation device.

上記断熱装置では、従来、断熱空間を形成するコア材を非通気性フィルムで被覆して内部を減圧状態に保持してある真空断熱パネルや、常圧の断熱空間を発泡ウレタンなどの弾性発泡樹脂で形成してある発泡樹脂断熱パネルを、隣り合う断熱パネルの周方向端面どうしが対向するように取り付けて、筒状の被断熱面を断熱可能に構成してある（周知慣用技術であり適切な先行技術文献を開示できない）。   Conventionally, in the above heat insulating device, a vacuum insulating panel in which the core material forming the heat insulating space is covered with a non-breathable film and the inside is kept in a reduced pressure state, or the normal pressure insulating space is an elastic foam resin such as urethane foam. Are attached so that the circumferential end surfaces of adjacent heat insulation panels face each other, and the cylindrical heat-insulated surface can be insulated (a well-known conventional technique and appropriate) Prior art documents cannot be disclosed).

真空断熱パネルを被断熱面に取り付ける断熱装置では、真空断熱パネルの熱抵抗が発泡樹脂断熱パネルに比べて大きいので、被断熱面の外側に断熱パネル取り付け用の広い空間を特に確保することなく高い断熱性能を確保することができ、断熱装置の小型化を図り易い利点があるが、真空断熱パネルはコア材を非通気性フィルムで被覆して内部を減圧状態に保持してあるので、非通気性フィルムを傷付けると減圧状態に保持できなくなって断熱性能が低下するおそれがあり、保管時や運搬時、被断熱面への取り付け作業時などに非通気性フィルムを傷付けないように、発泡樹脂断熱パネルに比べて、取り扱いに注意を要する欠点がある。
一方、発泡樹脂断熱パネルを被断熱面に取り付ける断熱装置では、発泡樹脂断熱パネルの表面を仮に傷付けるようなことがあっても断熱性能が低下し難いので、保管時や運搬時、被断熱面への取り付け作業時などに、真空断熱パネルに比べて簡便に取り扱える利点があるが、発泡樹脂断熱パネルの熱抵抗が真空断熱パネルに比べて小さいので、高い断熱性能を確保するためには厚さが厚い発泡樹脂断熱パネルを取り付ける必要があり、断熱装置が大型化するとともに、被断熱面の外側に断熱パネル取り付け用の広い空間を確保する必要があるという欠点がある。
本発明は上記実情に鑑みてなされたものであって、高い断熱性能を確保し易い真空断熱パネルの利点と、真空断熱パネルに比べて簡便に取り扱える発泡樹脂断熱パネルの利点とを生かして、発泡樹脂断熱パネルよりも断熱性能が高い断熱パネルを被断熱面に取り付けて断熱装置の小型化を図れるようにしながら、その断熱パネルを、被断熱面への取り付け作業を煩雑化することなく、保管時や運搬時、被断熱面への取り付け作業時などに簡便に取り扱えるようにすることを目的とする。 In a heat insulation device that attaches a vacuum heat insulation panel to a surface to be insulated, the heat resistance of the vacuum heat insulation panel is larger than that of a foamed resin heat insulation panel, so it is high without particularly securing a large space for attaching the heat insulation panel outside the surface to be insulated. Heat insulation performance can be secured, and there is an advantage that it is easy to reduce the size of the heat insulation device. However, the vacuum insulation panel covers the core material with a non-breathable film and keeps the inside in a reduced pressure state. If the film is damaged, it may not be possible to maintain a reduced pressure condition, and the heat insulation performance may be reduced.Insulate the foamed resin so that it does not damage the non-breathable film during storage, transportation, or installation on a surface to be insulated. Compared to panels, there is a drawback that requires careful handling.
On the other hand, in a heat insulation device that attaches a foamed resin insulation panel to a surface to be insulated, even if the surface of the foamed resin insulation panel is damaged, the insulation performance is unlikely to deteriorate. There is an advantage that it can be handled easily compared to the vacuum insulation panel during the installation work, but since the thermal resistance of the foamed resin insulation panel is smaller than that of the vacuum insulation panel, the thickness is required to ensure high insulation performance. It is necessary to attach a thick foamed resin heat insulating panel, and there is a drawback that it is necessary to secure a large space for attaching the heat insulating panel outside the surface to be insulated, as the heat insulating device becomes larger.
The present invention has been made in view of the above circumstances, taking advantage of the advantage of a vacuum heat insulation panel that easily ensures high heat insulation performance and the advantage of a foamed resin heat insulation panel that can be handled more easily than a vacuum heat insulation panel. While installing a heat insulation panel with higher heat insulation performance than a resin heat insulation panel on the surface to be insulated to reduce the size of the heat insulation device, the heat insulation panel can be stored without complicating the work of attaching to the surface to be insulated. It is intended to make it easy to handle when transporting or mounting on an insulated surface.

本発明の第１特徴構成は、筒状の被断熱面に、周方向に沿って複数の断熱パネルを隣り合う断熱パネルの周方向端面どうしが対向するように取り付けて、前記被断熱面を断熱可能に構成してある断熱装置であって、前記断熱パネルの夫々は、前記被断熱面側の一側面を前記被断熱面に略沿う形状に形成してある真空断熱パネルの他側面に弾性発泡樹脂層を積層して構成してあり、前記弾性発泡樹脂層を、前記真空断熱パネルの前記他側面に接着するように発泡樹脂材料を成型して、前記真空断熱パネルと一体に積層してある点にある。   In the first characteristic configuration of the present invention, a plurality of heat insulating panels are attached to a cylindrical heat insulating surface along the circumferential direction so that the circumferential end surfaces of adjacent heat insulating panels face each other, and the heat insulating surface is insulated. Each of the heat insulation panels is configured to be elastically foamed on the other side of the vacuum heat insulation panel formed in a shape substantially along the heat insulation surface. A resin layer is laminated to form the foamed resin material so that the elastic foamed resin layer is bonded to the other side surface of the vacuum heat insulation panel, and is laminated integrally with the vacuum heat insulation panel. In the point.

〔作用及び効果〕
断熱パネルの夫々は、被断熱面側の一側面を被断熱面に略沿う形状に形成してある真空断熱パネルの他側面に弾性発泡樹脂層を積層して構成してあるので、真空断熱パネルの一側面側を被断熱面に略沿わせて取り付けて、高い断熱性能を確保できるとともに、弾性発泡樹脂層で断熱性能を更に高めながら、その弾性発泡樹脂層を真空断熱パネルの傷付きを防止する保護層として機能させることができる。
また、真空断熱パネルの他側面に弾性発泡樹脂層を積層するにあたって、真空断熱パネルの他側面に接着するように発泡樹脂材料を成型して、弾性発泡樹脂層を真空断熱パネルと一体に積層してあるので、被断熱面への取り付け作業時に、真空断熱パネルの他側面に弾性発泡樹脂層を別途組み付けるような手間を掛けることなく取り付けることができる。
従って、発泡樹脂断熱パネルよりも断熱性能が高い断熱パネルを被断熱面に取り付けて断熱装置の小型化を図れるようにしながら、その断熱パネルを、被断熱面への取り付け作業を煩雑化することなく、保管時や運搬時、取り付け作業時などに簡便に取り扱える。 [Action and effect]
Each of the heat insulation panels is formed by laminating an elastic foamed resin layer on the other side of the vacuum heat insulation panel formed on one side of the heat insulation surface in a shape substantially along the heat insulation surface. The side of the side of the heat sink can be mounted along the heat-insulated surface to ensure high heat insulation performance, while the elastic foam resin layer further enhances the heat insulation performance while preventing damage to the vacuum heat insulation panel. It can function as a protective layer.
In addition, when laminating the elastic foam resin layer on the other side of the vacuum heat insulation panel, the foam resin material is molded so as to adhere to the other side of the vacuum heat insulation panel, and the elastic foam resin layer is laminated integrally with the vacuum heat insulation panel. Therefore, it is possible to attach the elastic foamed resin layer to the other side surface of the vacuum heat insulating panel without taking the trouble of attaching the elastic foamed resin layer to the other side of the vacuum heat insulating panel.
Therefore, it is possible to reduce the size of the heat insulation device by attaching a heat insulation panel having higher heat insulation performance than the foamed resin heat insulation panel to the heat insulation surface, and without complicating the work of attaching the heat insulation panel to the heat insulation surface. Can be easily handled during storage, transportation and installation.

本発明の第２特徴構成は、前記断熱パネルの前記被断熱面側に向ける内面に、軟質フォーム層を設けてある点にある。   The 2nd characteristic structure of this invention exists in the point which provided the flexible foam layer in the inner surface which faces the said to-be-insulated surface side of the said heat insulation panel.

〔作用及び効果〕
真空断熱パネルはコア材を非通気性フィルムで被覆して内部を減圧状態に保持してあるので、減圧時に非通気性フィルムに皺が寄り易く、真空断熱パネルの一側面側を被断熱面に略沿わせて取り付けても、真空断熱パネルと被断熱面との間に断熱性能を低下させる空間ができ易いが、断熱パネルの被断熱面側に向ける内面に、軟質フォーム層を設けてあるので、真空断熱パネルと被断熱面との間に空間ができないように、軟質フォーム層を真空断熱パネルの一側面に沿って変形させた状態で充填することができ、高い断熱性能を長期に亘って維持し易い。 [Action and effect]
The vacuum insulation panel covers the core material with a non-breathable film and keeps the inside in a depressurized state. Even if it is mounted almost along, it is easy to create a space that reduces the heat insulation performance between the vacuum insulation panel and the surface to be insulated, but because the flexible foam layer is provided on the inner surface of the insulation panel facing the surface to be insulated The flexible foam layer can be filled in a deformed state along one side of the vacuum insulation panel so that there is no space between the vacuum insulation panel and the surface to be insulated, and high insulation performance can be maintained for a long time. Easy to maintain.

本発明の第３特徴構成は、前記断熱パネルの前記周方向端面に、軟質フォーム層を設けてある点にある。   The 3rd characteristic structure of this invention exists in the point which provided the flexible foam layer in the said circumferential direction end surface of the said heat insulation panel.

〔作用及び効果〕
周方向で隣り合う断熱パネルどうしを互いに突き合わせる際に、周方向端面に設けた軟質フォーム層が変形することによって、周方向端面どうしの間に隙間ができないようになり、より高い断熱性能を長期に亘って維持し易い。 [Action and effect]
When the thermal insulation panels that are adjacent to each other in the circumferential direction are brought into contact with each other, the soft foam layer provided on the circumferential end faces is deformed, so that there is no gap between the circumferential end faces, resulting in higher insulation performance for a long time. Easy to maintain.

本発明の第４特徴構成は、前記弾性発泡樹脂層の外周側に、防湿フィルム層を設けてある点にある。   The 4th characteristic structure of this invention exists in the point which has provided the moisture proof film layer in the outer peripheral side of the said elastic foamed resin layer.

〔作用及び効果〕
弾性発泡樹脂層の外周側に防湿フィルム層を設けてあるので、結露の原因になるような水蒸気を含んだ外部空気が弾性発泡樹脂層側に入り込み難くなり、高い断熱性能を長期に亘って維持し易い。 [Action and effect]
Since a moisture-proof film layer is provided on the outer peripheral side of the elastic foam resin layer, it is difficult for external air containing water vapor that may cause dew condensation to enter the elastic foam resin layer side, maintaining high thermal insulation performance over a long period of time. Easy to do.
