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、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。
【0010】
請求項1に記載の発明では、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に対して、真空断熱材における対象物に密着させる密着面を保持具の取付面と同じ側に向けて、真空断熱材の溶着部を挟持部に挟持させた後、保持具の取付面を対象物に密着固定することにより、真空断熱材の密着面を対象物に密着した状態で固定するため、真空断熱材を、簡単に強固に固定でき、また、接着剤や接着テープ類を使用しないので、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いのでコスト上昇を防ぐことができ、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、真空断熱材の一部に外力が集中して加わらないので、真空断熱材が損傷し難く、高い断熱性能を長期に亘って維持することができるという作用を有する。
【0011】
また、請求項2記載の真空断熱材の保持具の発明は、請求項1記載の発明において、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、前記真空断熱材の溶着部と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いものである。
【0012】
請求項2に記載の発明では、請求項1記載の発明の作用に加えて、保持具に保持された真空断熱材の全体より大きい平面を有する対象物に対して、真空断熱材を保持した保持具の取付面を対象物の平面に密着固定した場合に、真空断熱材の密着面を対象物に密着させることができるという作用を有する。
【0013】
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。
【0014】
また、請求項3記載の真空断熱材の保持具の発明は、請求項1または2記載の発明において、真空断熱材の溶着部を挟持部に挟持させる際に前記真空断熱材が接触する可能性のある箇所と前記溶着部を挟持部に挟持させた前記真空断熱材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たものであり、請求項1または2記載の発明の作用に加えて、真空断熱材が保持具に接触することによる真空断熱材の損傷の可能性を少なくし、真空断熱材に保持具を取り付ける作業と真空断熱材を対象物に密着させる作業の作業性を容易にすると共に、その作業時の真空断熱材の損傷による不良品の発生を抑え、断熱性能について高い信頼性が得られるという作用を有する。
【0015】
また、請求項4記載の真空断熱材の保持具の発明は、請求項1から3のいずれか一項記載の発明において、溶着部が挟持部に挟持された真空断熱材の取外し、取替えが可能に挟持部を構成したものであり、請求項1から3のいずれか一項記載の発明の作用に加えて、真空断熱材が破損して断熱性能が劣化した場合または経年劣化した場合に、真空断熱材を取替えることにより、低コストで、簡単に、初期の断熱性能を取り戻すことができるという作用を有する。
【0016】
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、挟持部を、合体する二部品で構成し、前記二部品における互いに対向する面で真空断熱材の溶着部を挟持するものであり、挟持部を構成することになる合体前の二部品の間に真空断熱材の溶着部を配置した後、その二部品を合体させて真空断熱材の溶着部をその二部品で挟持することができる。
【0017】
したがって、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、真空断熱材の溶着部を簡単にしっかりと挟持することができ、それにより、長期に亘って真空断熱材を対象物に密着させることができ、また、真空断熱材の溶着部を挟持させる際に、真空断熱材に大きな負担(外力)がかからないため、真空断熱材が破損する可能性が少なく、高い断熱性能を長期に亘って維持することができるという作用を有する。
【0018】
また、請求項6記載の真空断熱材の保持具の発明は、請求項5記載の発明において、二部品は、互いに係合するように構成されているものであり、請求項5記載の発明の作用に加えて、係合する構造により二部品の合体時の位置ズレを防止でき、係合する構造を二部品同士の固定に利用することも可能であるという作用を有する。
【0019】
また、請求項7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、挟持部を、固定片と、一端が前記固定片に固定され他端が前記一端を回動軸として回動する可動片とで構成し、前記固定片と前記可動片とにおける互いに対向する面で真空断熱材の溶着部を挟持するものであり、可動片を固定片から離した状態において可動片と固定片との間に真空断熱材の溶着部を配置した後、可動片を回動して固定片に合わせて、真空断熱材の溶着部を固定片と可動片とにおける互いに対向する面で挟持することができる。
【0020】
したがって、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、真空断熱材の溶着部を簡単にしっかりと挟持することができ、それにより、長期に亘って真空断熱材を対象物に密着させることができ、また、真空断熱材の溶着部を挟持させる際に、真空断熱材に大きな負担(外力)がかからないため、真空断熱材が破損する可能性が少なく、高い断熱性能を長期に亘って維持することができるという作用を有する。また、可動片は固定片と一体に構成されているので管理しやすいという作用を有する。
【0021】
また、請求項8記載の真空断熱材の保持具の発明は、請求項7記載の発明において、固定片と可動片とは、互いに係合するように構成されているものであり、請求項7記載の発明の作用に加えて、係合する構造により固定片と可動片との合体時の位置ズレを防止でき、係合する構造を固定片と可動片との固定に利用することも可能であるという作用を有する。
【0022】
また、請求項9記載の真空断熱材の保持具の発明は、請求項1から8のいずれか一項記載の発明において、真空断熱材の密着面と前記密着面の反対側の面を除く前記真空断熱材の外周面に外力が加わることを防止可能に、前記外周面に近接し前記外周面を覆う外周面保護部を有するものであり、請求項1から8のいずれか一項記載の発明の作用に加えて、外周面保護部が、真空断熱材の外周面(真空断熱材の密着面とこの密着面の反対側の面を除く外周面)に近接し、外周面を覆うことにより、真空断熱材の外周面に外力が加わることを防止するため、真空断熱材の外周面が破損する可能性を大幅に少なくし、外力に対して強く高い断熱性能を長期に亘って維持することができるという作用を有する。
【0023】
また、請求項10記載の真空断熱材の保持具の発明は、請求項1から9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9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。
【0024】
また、請求項11記載の真空断熱材の保持具の発明は、請求項1から9のいずれか一項記載の発明において、真空断熱材の密着面の反対側の面を覆う露出面保護部を有するものであり、請求項1から9のいずれか一項記載の発明の作用に加えて、保持具の露出面保護部が真空断熱材の密着面の反対側の面を覆うので、保持具に保持された真空断熱材を対象物に取り付ける作業時およびその作業後に、誤って真空断熱材の密着面の反対側の面を外力で損傷させる可能性が大幅に減り、対象物に真空断熱材を取り付ける作業が容易になると共に、断熱性能を長期に亘って維持することができるという作用を有する。
【0025】
さらに、外周面保護部などにより真空断熱材の外周部の全周が保護されている場合は、真空断熱材の密着面を除く真空断熱材の他の全ての面が外力から保護されることになるため、真空断熱材の外周部や密着面の反対側の面に外力が加わるために真空断熱材の損傷を怖れて従来では取付けできなかった箇所にも真空断熱材を取付ることができるようになり、真空断熱材の適用範囲を拡大できるという作用を有する。
【0026】
また、請求項12記載の真空断熱材の保持具の発明は、請求項1から11のいずれか一項記載の発明において、別部品の取付具で対象物に取付固定し易いように取付用加工が施されているものであり、請求項1から11のいずれか一項記載の発明の作用に加えて、保持具に施されている取付用加工により別部品の取付具で真空断熱材を対象物に取付固定し易いという作用を有する。

【0028】
また、請求項14記載の真空断熱材の保持具の発明は、請求項1から13のいずれか一項記載の発明において、硬質樹脂または金属で構成されたものであり、請求項1から13のいずれか一項記載の発明の作用に加えて、保持具を金属または樹脂で造ると、経年変化による真空断熱材の外れがなく、一定の力で取り付けることができるので安定した断熱性能を維持することができるという作用を有する。
【0029】
また、請求項15記載の真空断熱材の保持具の発明は、請求項1から14のいずれか一項記載の発明において、真空断熱材に当接する部分を他の部分より軟質の材料で構成したものであり、請求項1から14のいずれか一項記載の発明の作用に加えて、保持具における真空断熱材に当接する部分を他の部分より軟質の材料で構成したので、真空断熱材が保持具に当接することによる真空断熱材の損傷の可能性を少なくできるという作用を有する。
【0030】
また、請求項16記載の真空断熱材の取付方法の発明は、請求項1から15のいずれか一項記載の真空断熱材の保持具を使用し、真空断熱材における対象物に密着させる密着面を前記保持具の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た後、前記取付面を前記対象物に密着固定することにより、前記真空断熱材の前記密着面を前記対象物に密着した状態で固定するものである。
【0031】
請求項16記載の発明では、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、簡単に強固に固定でき、また、接着剤や接着テープ類を使用しないので、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いのでコスト上昇を防ぐことができ、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、真空断熱材の一部に外力が集中して加わらないので、真空断熱材が損傷し難く、高い断熱性能を長期に亘って維持することができるという作用を有する。
【0032】
【発明の実施の形態】
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。
【0033】
(実施の形態1)
図1は、本発明の実施の形態1による真空断熱材の保持具の使用例を示す分解斜視図、図2は同実施の形態の真空断熱材の保持具を適用する真空断熱材の一例の平面図、図3は同実施の形態の真空断熱材の保持具を真空断熱材に取り付けた状態を示す平面図、図4は同実施の形態の真空断熱材の保持具の取付状態を示す要部断面図、図5は同実施の形態の真空断熱材の保持具を真空断熱材に取り付けた状態を示す要部断面図、図6は同実施の形態の真空断熱材の保持具を介して真空断熱材を対象物に取り付けた状態を示す要部断面図である。
【0034】
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。
【0035】
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。
【0036】
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。
【0037】
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。
【0038】
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。
【0039】
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。
【0040】
また、本実施の形態では、溶着部4が挟持部7に挟持された真空断熱材1の取外し、取替えが可能になるように、挟持部7を、保持具5aの一部と、保持具5bの一部の、合体、分解可能な二部品で構成しており、二部品(保持具5a,5b)における互いに対向する面で真空断熱材1の溶着部4を挟持する。
【0041】
また、二部品(保持具5a,5b)は、保持具5aに係合凹部15a、保持具5bに係合凸部15b)を有し、係合凹部15aと係合凸部15bとが互いに係合するように、構成されている。
【0042】
また、本実施の形態の保持具5a,5bは、対向する二面のどちらも取付面8とすることが可能に、係合部(保持具5aの係合凹部15aと、保持具5bの係合凸部15b)を除いて、保持具5aと保持具5bとを面対称に構成している。
【0043】
また、本実施の形態の保持具5a,5bは、別部品のネジ(取付具)13で対象物6に真空断熱材1を取付固定し易いように貫通孔(取付用加工)14が施されており、貫通孔14は、真空断熱材1の溶着部4を避けて設けられる。
【0044】
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。
【0045】
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。
【0046】
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。
【0047】
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。
【0048】
以上のように本実施の形態の真空断熱材1の保持具5a,5bは、芯材2をガスバリアー性の外被材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4を有する板状の真空断熱材1を、対象物6に密着固定するときに用いるものであって、真空断熱材1の溶着部4を挟持する挟持部7と、対象物6に密着させられる取付面8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ものである。
【0049】
本実施の形態の真空断熱材1の保持具5a,5bでは、芯材2をガスバリアー性の外被材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4を有する板状の真空断熱材1に対して、真空断熱材1における対象物6に密着させる密着面10を保持具5a,5bの取付面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に挟持させた後、保持具5a,5bの取付面8を対象物6に密着固定することにより、真空断熱材1の密着面10を対象物6に密着した状態で固定するため、真空断熱材1を、簡単に強固に固定でき、また、接着剤や接着テープ類を使用しないので、真空断熱材1の外被材3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いのでコスト上昇を防ぐことができ、また、真空断熱材1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1の一部に外力が集中して加わらないので、真空断熱材1が損傷し難く、高い断熱性能を長期に亘って維持することができる。
【0050】
また、本実施の形態の真空断熱材1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いか同等であり、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ものである。
【0051】
