Description

【０００１】
【発明の属する技術分野】
本発明は、真空断熱材の保持具と、その保持具を使用した真空断熱材の取付方法に関するものである。
【０００２】
【従来の技術】
近年、断熱性能の高い断熱材として、芯材をガスバリアー性の外被材で被って外被材の内部を減圧し外被材の開口部を溶着してなる真空断熱材が注目されている。
【０００３】
従来、真空断熱材は、接着剤や両面接着テープにより真空断熱材の密着面を対象物に貼り付けていた（特開昭６３−２０４０８９号公報参照）。
【０００４】
または、真空断熱材の外被材の溶着部に貫通孔をあけ、この貫通孔に取付けた取付具を使って真空断熱材を所定位置に固定していた（特開昭５８−７８０８２号公報、特開昭５８−１２７０８４号公報参照）。
【０００５】
【発明が解決しようとする課題】
しかしながら、接着剤や両面接着テープを使用する場合は、貼付作業困難で時間がかかり、接着強度が弱く、また、経年変化により接着強度が低下する傾向にあり、真空断熱材を剥がす方向の外力が真空断熱材に加わった時に、真空断熱材の脱落やはずれが生じてしまい、しいては断熱効果の低下を招いてしまうという欠点があった。
【０００６】
また、接着剤や接着テープ類に対し耐薬品性を持っている外被材を選定しなくてはならず、材料費のコスト上昇を招いてしまうという欠点があった。
【０００７】
また、真空断熱材の溶着部の貫通孔に取付具を取付ける場合は、貫通孔をあけることにより有効溶着部が減って溶着部のシール性が低下し、貫通孔に外力が集中して加わりやすく、貫通孔が拡がったり、貫通孔に付いた傷が拡がったりする虞があり、その場合、真空断熱材の内部圧力が上昇し、断熱性能が低下するという問題点であった。
【０００８】
本発明は、上記従来の課題を解決するもので、真空断熱材を、簡単に強固に固定でき、また、真空断熱材の外被材に接着剤や接着テープ類に対し耐薬品性を持っている特別な外被材を使用する必要がなく、また、真空断熱材側に取付けのため貫通孔などの加工をする必要がなく、真空断熱材が損傷し難い真空断熱材の保持具と、その保持具を使用した真空断熱材の取付方法を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するために本発明の請求項１記載の真空断熱材の保持具の発明は、芯材をガスバリアー性の外被材で被って前記外被材の内部を減圧し前記外被材の開口部を溶着してなり外周部の少なくとも対向する二辺にヒレ状の溶着部を有する板状の真空断熱材を、対象物に密着固定するときに用いるものであって、前記真空断熱材の前記溶着部を挟持する挟持部と前記対象物に密着させられる取付面とを有し互いに対向する面で前記真空断熱材の前記溶着部を挟持する二部品と、前記真空断熱材の前記溶着部を避けて前記二部品の両方を貫通して前記二部品と前記真空断熱材とを前記対象物に固定するネジとからなり、前記挟持部と前記取付面との前記真空断熱材の厚み方向の距離の大きさが、前記真空断熱材の前記溶着部と前記密着面との前記真空断熱材の厚み方向の距離の大きさより小さいか同等であり、両者の距離の差は、前記溶着部が前記挟持部に挟持された状態の前記真空断熱材が破損しない範囲で前記密着面が没入する方向に変位可能な最大移動距離の大きさより小さく、前記真空断熱材における前記対象物に密着させる密着面を前記取付面と同じ側に向けて前記真空断熱材の前記溶着部を前記挟持部に挟持させて、前記取付面を前記対象物に密着固定した場合に、前記真空断熱材の前記密着面が前記対象物に密着した状態で固定されるものである。

【００１１】
特に、挟持部と取付面との真空断熱材の厚み方向の距離の大きさが、真空断熱材の溶着部と密着面との真空断熱材の厚み方向の距離の大きさより小さい（但し、両者の距離の差は、前記溶着部が前記挟持部に挟持された状態の前記真空断熱材が破損しない範囲で前記密着面が没入する方向に変位可能な最大移動距離の大きさより小さいものとする）場合は、対象物に対する真空断熱材の密着力を強くして、長期に亘って、対象物と真空断熱材との間に隙間ができるのを防止でき、断熱効果を高めることができるという作用を有する。

【００１７】
また、請求項５記載の真空断熱材の保持具の発明は、請求項１から４のいずれか一項記載の発明において、対向する二面のどちらも取付面とすることが可能に構成されたものであり、請求項１から４のいずれか一項記載の発明の作用に加えて、真空断熱材の密着面が表裏のどちらの面であるかを気にせずに、真空断熱材に保持具を取り付けることができ、真空断熱材に保持具を取り付ける作業が容易になるという作用を有する。さらに、真空断熱材が表裏対称の構造になっている場合などで、表面、裏面のどちらを密着面としても構わない場合は、保持具の正しい取付面が表裏のどちらの面であるかを気にせずに、保持具に保持された真空断熱材を対象物に取り付けることができ、対象物に真空断熱材を取り付ける作業が容易になるという作用を有する。
【００１８】

以下、本発明による真空断熱材の保持具の一実施の形態について、図面を参照しながら説明する。
【００２２】

【００２３】
図において、１は板状の真空断熱材であり、シート状無機繊維成形体からなる芯材２をガスバリアー性のラミネートフィルムからなる外被材３で被って外被材３の内部を減圧し外被材３の開口部を熱溶着してなり外周部にヒレ状の溶着部４を有する。
【００２４】
一例として、この真空断熱材１の作製手順を説明する。厚さ５mmのシート状無機繊維成形体を４枚積層してなる芯材２を１３０℃で１時間乾燥する。その後、ガスバリアー性のラミネートフィルムからなる外被材３で被って、内部を１０パスカルまで減圧する。さらに、開口部を熱溶着し封止したものが真空断熱材１である。
【００２５】
５ａ，５ｂは、真空断熱材１を対象物６に密着固定するときに用いる一対の保持具であり、真空断熱材１の溶着部４を挟持する軟質材からなる挟持部７と、対象物６に密着させられる取付面８と、真空断熱材１の外周面９（真空断熱材１の密着面１０と密着面１０の反対側の面１１を除く外周面９）に外力が加わることを防止可能に、外周面９に近接し外周面９を覆う外周面保護部１２（挟持部７と一体に軟質材で構成）と、ネジ１３で対象物６に取付固定するのに好適な貫通孔（取付用加工）１４と、係合部（保持具５ａに係合凹部１５ａ、保持具５ｂに係合凸部１５ｂ）とを有し、真空断熱材１における対象物６に密着させる密着面１０を取付面８と同じ側に向けて真空断熱材１の溶着部４を挟持部７に挟持させて、取付面８を対象物６に密着固定した場合に、真空断熱材１の密着面１０が対象物６に密着した状態で固定される。
【００２６】
本実施の形態の保持具５ａ，５ｂは、挟持部７と取付面８との真空断熱材１の厚み方向の距離の大きさが、真空断熱材１の溶着部４と密着面１０との真空断熱材１の厚み方向の距離の大きさより小さく、両者の距離の差は、溶着部４が挟持部７に挟持された状態の真空断熱材１が破損しない範囲で密着面１０が没入する方向に変位可能な最大移動距離の大きさより小さい。
【００２７】
なお、本実施の形態では、保持具５ａ，５ｂの挟持部７と取付面８との真空断熱材１の厚み方向の距離の大きさを、真空断熱材１の溶着部４と密着面１０との真空断熱材１の厚み方向の距離の大きさより小さくしているが、両者の距離の差をなくしても（同等の距離としても）構わない。
【００２８】
また、本実施の形態の保持具５ａ，５ｂは、真空断熱材１の溶着部４を挟持部７に挟持させる際に真空断熱材１が接触する可能性のある箇所と溶着部４を挟持部７に挟持させた真空断熱材１が接触する可能性のある箇所の角部を、面取りまたは緩やかな曲面に加工している。

【００３３】
本実施の形態の軟質材部分を除く保持具５ａ，５ｂの材質は、樹脂製または金属製が一般的であるが、断熱性能を重視する場合は熱伝導率の低い樹脂製、また取り付け強度や耐久性を重視するのであれば金属製など、場合によって使い分けることができる。
【００３４】
また、保持具５ｂの係合凸部１５ｂは、保持具５ａの係合凹部１５ａと位置合わせし易いように先端の角部を、例えば４５度面取りやＲ加工などの緩やかな曲面に加工することが好ましい。
【００３５】
本実施の形態で使用している真空断熱材１は、厚さ５mmのシート状無機繊維成形体を４枚積層してなる芯材２を使用しているが、芯材２として、厚さ２０mmのシート状無機繊維成形体を１枚を使用しても良く、使用するシート状無機繊維成形体の厚みや積層する枚数は自由であり、断熱性能に応じた芯材２の厚みを選定し、真空断熱材１を製作することが可能である。
【００３６】
本実施の形態では、真空断熱材１を保持した保持具５ａ，５ｂを、ネジ１３で対象物６に固定しているが、保持具５ａ，５ｂ部分で接着剤や両面テープ等を用いて取り付けても良い。真空断熱材１の対象物６への固定は、真空断熱材１に外力が加わらないよう保持具５ａ，５ｂを利用し取り付けることが望ましい。

Description of the Related Art In recent years, vacuum heat insulating materials that have a core material covered with a gas barrier outer covering material, depressurize the inside of the outer covering material, and weld the opening of the outer covering material have attracted attention as a heat insulating material with high heat insulating performance. .
[0003]
  Conventionally, the vacuum heat insulating material has adhered the contact | adherence surface of the vacuum heat insulating material to the target object with the adhesive agent or the double-sided adhesive tape (refer Unexamined-Japanese-Patent No. 63-204089).
[0004]
  Alternatively, a through-hole is formed in the welded portion of the jacket of the vacuum heat insulating material, and the vacuum heat insulating material is fixed at a predetermined position by using a fixture attached to the through-hole (Japanese Patent Laid-Open No. 58-78082, Japanese Patent Laid-Open No. 58-127084).
[0005]
[Problems to be solved by the invention]
  However, when an adhesive or double-sided adhesive tape is used, the sticking operation is difficult and time consuming, the adhesive strength is weak, and the adhesive strength tends to decrease due to secular change, and there is an external force in the direction of peeling the vacuum heat insulating material. When added to the vacuum heat insulating material, the vacuum heat insulating material falls off or comes off, which leads to a decrease in the heat insulating effect.
[0006]
  In addition, a covering material having chemical resistance to the adhesive and the adhesive tape has to be selected, which causes a disadvantage of increasing the material cost.
[0007]
  In addition, when attaching a fixture to the through hole of the vacuum insulation material welded part, the effective welded part is reduced by opening the through hole, the sealing performance of the welded part is lowered, and external force is concentrated and easily applied to the through hole. There is a possibility that the through-holes may be expanded or the scratches attached to the through-holes may be expanded. In this case, the internal pressure of the vacuum heat insulating material is increased and the heat insulating performance is deteriorated.
[0008]
  The present invention solves the above-mentioned conventional problems. The vacuum heat insulating material can be easily and firmly fixed, and the outer cover material of the vacuum heat insulating material has chemical resistance against adhesives and adhesive tapes. There is no need to use a special jacket material, and there is no need to process through holes etc. for mounting on the vacuum insulation material side, and the vacuum insulation material holder that is difficult to damage the vacuum insulation material, and its It aims at providing the attachment method of the vacuum heat insulating material which uses a holder.
