Description

本発明は、真空断熱パネルと枠体とを組み合わせた断熱構造体に関する。 The present invention relates to a heat insulating structure in which a vacuum heat insulating panel and a frame are combined.

内部を空間としたパネル内にグラスウールの繊維同士を結合させた芯材を入れ、この状態でパネル内を真空にすることで断熱効果を高めた真空断熱材が知られている。   There is known a vacuum heat insulating material in which a heat insulating effect is enhanced by putting a core material in which glass wool fibers are bonded together in a panel having a space inside, and evacuating the inside of the panel in this state.

前記パネルとしては特許文献１に開示されるように、樹脂フィルムや樹脂板、或いは金属箔と樹脂フィルムの積層構造フィルムを用いるのが一般的である。この特許文献１に開示される真空断熱パネルは図５（ａ）に示すように、２枚の板材５０,５０を貼り合わせてパネルとしている。そのため、周囲にはフランジ部５１が形成されている。
真空断熱パネルのケースの材料を特許文献１のように樹脂とした場合には、特許文献２或いは図５（ｂ）に示すように、フランジ部を設けない形状とすることも可能である。 As the panel, as disclosed in Patent Document 1, a resin film, a resin plate, or a laminated structure film of a metal foil and a resin film is generally used. As shown in FIG. 5A, the vacuum heat insulating panel disclosed in Patent Document 1 is formed by bonding two plate members 50 and 50 together. Therefore, a flange portion 51 is formed around the periphery.
When the material of the case of the vacuum heat insulation panel is made of resin as in Patent Document 1, it is possible to form a shape without providing a flange portion as shown in Patent Document 2 or FIG.

真空断熱材において問題となるのは、樹脂フィルムや積層フィルムなどのパネル（外皮）を透過して、ガスがパネル内側の真空空間に侵入し、内部圧が上がって真空度が下がり断熱効果が悪化することである。   The problem with vacuum insulation is that it penetrates the panel (outer skin) of resin film or laminated film, gas enters the vacuum space inside the panel, the internal pressure rises, the degree of vacuum decreases, and the heat insulation effect deteriorates. It is to be.

ガスの透過性の観点からは、樹脂よりもステンレスやアルミなどの金属の方がガスを透過しにくい。しかしながら、金属シートにてパネルを構成する場合には２枚の金属シートの周囲を貼り合わせることになるので、必然的にフランジ部が形成されることになる。このフランジ部の部分は真空の空間がないため、断熱効果が悪くなる。   From the viewpoint of gas permeability, metals such as stainless steel and aluminum are less likely to permeate gases than resins. However, in the case where the panel is formed of a metal sheet, the periphery of the two metal sheets is bonded together, so that a flange portion is inevitably formed. Since the flange portion has no vacuum space, the heat insulating effect is deteriorated.

上記の課題を解決するため本発明に係る断熱構造体は、真空断熱パネルと断熱性を有する枠体とを組み合わせてなり、前記真空断熱パネルは２枚のステンレスなどの金属シートを溶接などの手段で貼り合わせることで、芯材を収納する中空部とその周囲のフランジ部が形成され、前記枠体は木材、プラスチック、発泡系断熱材、無機繊維系断熱材などからなるとともに、壁などの躯体に取り付けられまた前記フランジ部が嵌り込む溝部が形成された構造である。 In order to solve the above problems, a heat insulating structure according to the present invention is a combination of a vacuum heat insulating panel and a frame having heat insulating properties, and the vacuum heat insulating panel is a means such as welding two metal sheets such as stainless steel. by bonding in a flange portion surrounding the hollow portion is formed for accommodating the core member, the frame wood, plastic, foamed-based heat insulating material, with the like inorganic fiber based insulation, wall etc. It is a structure in which a groove portion is formed which is attached to the housing and into which the flange portion is fitted.

また、枠体を横メンバと縦メンバに分割することで、真空断熱パネルの継ぎ足しが可能となり、必要な部分に真空断熱パネルを取り付けることができる。 Further, by dividing the frame body into the horizontal member and the vertical member, the vacuum heat insulation panel can be added, and the vacuum heat insulation panel can be attached to a necessary portion.

本発明に係る断熱構造体によれば、ガスが透過しにくい金属シートによってパネルを形成した場合に問題になる断熱構造体のフランジ部での断熱効果の低下を効果的に防ぐことができる。   According to the heat insulating structure according to the present invention, it is possible to effectively prevent a decrease in the heat insulating effect at the flange portion of the heat insulating structure, which becomes a problem when the panel is formed of a metal sheet that is difficult to transmit gas.

本発明に係る断熱構造体の正面図Front view of heat insulation structure according to the present invention 図１のＡ−Ａ方向矢視図AA direction arrow view of FIG. 図２の要部拡大断面図2 is an enlarged cross-sectional view of the main part of FIG. 真空断熱パネルの別実施例を示す図The figure which shows another Example of a vacuum heat insulation panel （ａ）及び（ｂ）は従来の断熱構造を示す図(A) And (b) is a figure which shows the conventional heat insulation structure.

以下に本発明の実施例を添付図面に基づいて説明する。本発明に係る断熱構造体は、真空断熱パネル１とこの真空断熱パネル１を壁などの躯体２に取り付ける断熱性の枠体３から構成される。 Embodiments of the present invention will be described below with reference to the accompanying drawings. The heat insulating structure according to the present invention includes a vacuum heat insulating panel 1 and a heat insulating frame 3 that attaches the vacuum heat insulating panel 1 to a housing 2 such as a wall.

前記真空断熱パネル１はケース１１と芯材１２からなり、ケース１１は２枚の金属シート、例えばステンレスシート１１ａを貼り合わせることで、周囲にフランジ部１１ｂを形成している。尚、ケース１１を構成する材料としてはステンレスに限らずアルミシート等他の金属シート、或いは金属シートと樹脂シートとの積層体でもよい。 The vacuum heat insulating panel 1 includes a case 11 and a core member 12. The case 11 is formed by bonding two metal sheets, for example, a stainless steel sheet 11a, to form a flange portion 11b around. The material constituting the case 11 is not limited to stainless steel, but may be another metal sheet such as an aluminum sheet, or a laminate of a metal sheet and a resin sheet.

フランジ部１１ｂの形状としては、２枚の金属シートを単に貼り合わせたものに限らず、図４に示すように、ヘミング加工によって折り返した形状でもよい。 The shape of the flange portion 11b is not limited to simply bonding two metal sheets, but may be a shape folded by hemming as shown in FIG.

またケース１１の真空引きされた空間内に収納される芯材１２はグラスウール繊維の交差部がフェノール樹脂や水ガラス等を接着剤として互いに接着した三次元構造をしている。このためケース１１が減圧された状態でもケースの形状維持が芯材によって図られる。 Further, the core material 12 housed in the vacuum-evacuated space of the case 11 has a three-dimensional structure in which the intersecting portions of the glass wool fibers are bonded to each other using phenol resin, water glass or the like as an adhesive. For this reason, even when the case 11 is decompressed, the shape of the case can be maintained by the core material.

前記枠体３の材料としては、断熱性に優れたものであればよく、例えば木材、プラスチック、発泡系断熱材、無機繊維系断熱材などが考えられる。 The material of the frame body 3, as long as it has excellent heat insulating property, such as wood, plastic, foamed-based heat insulating material, such as inorganic fibers based heat insulating material is considered.

前記枠体３は横メンバ３１,３２と縦メンバ３３,３４から構成される。この実施例にあっては、横メンバ３１の上辺に前記ケースのフランジ部１１ｂが嵌り込む溝部３１ａが形成され、横メンバ３２の上辺と下辺にも同様に溝部３２ａ、３２ｂが形成され、縦メンバ３３,３４の一方の側辺にも溝部３３ａ、３４ａが形成されている。 The frame 3 includes horizontal members 31 and 32 and vertical members 33 and 34. In this embodiment, a groove 31a into which the flange 11b of the case is fitted is formed on the upper side of the horizontal member 31, and grooves 32a and 32b are similarly formed on the upper and lower sides of the horizontal member 32. Grooves 33a, 34a are also formed on one side of 33, 34.

前記溝部の形状は全て同一であり、ケース１１周縁のフランジ部１１ａはどの溝部にも嵌り込む。また溝部の開口周辺は真空断熱パネル１を安定して保持するためテーパ面３１ｂとされている。 All the groove portions have the same shape, and the flange portion 11a on the periphery of the case 11 is fitted into any groove portion. The periphery of the opening of the groove is a tapered surface 31b in order to stably hold the vacuum heat insulating panel 1.

また前記横メンバ３１,３２はビス３５を介して躯体２に取り付けられる。
取り付けの手順は、先ず躯体２に横メンバ３１を取り付け、この横メンバ３１の溝部３１ａに真空断熱パネル１の下辺のフランジ部１１ａを挿入する。次いで、真空断熱パネル１の左右の側辺のフランジ部１１ａに縦メンバ３３,３４の溝部３３ａ、３４ａを嵌め込む。この後、真空断熱パネル１の上辺のフランジ部１１ａに横メンバ３２の下辺に形成した溝部３２ａを嵌め込み、この状態でビス３５を用いて横メンバ３２を躯体２に固定する。 The lateral members 31 and 32 are attached to the housing 2 via screws 35.
The attachment procedure is as follows. First, the horizontal member 31 is attached to the housing 2, and the flange portion 11 a on the lower side of the vacuum heat insulating panel 1 is inserted into the groove portion 31 a of the horizontal member 31. Next, the grooves 33 a and 34 a of the vertical members 33 and 34 are fitted into the flange portions 11 a on the left and right sides of the vacuum heat insulating panel 1. Thereafter, a groove 32 a formed on the lower side of the horizontal member 32 is fitted into the flange 11 a on the upper side of the vacuum heat insulating panel 1, and the horizontal member 32 is fixed to the housing 2 using screws 35 in this state.

以上の作業で１つの真空断熱パネル１が枠体を介して躯体２に固定されたことになるが、真空断熱パネル１を連続して多数固定する場合には、上記の操作を繰り返す。尚、図では上下方向に真空断熱パネル１を継ぎ足すことができる例をしめしたが、横方向に継ぎ足すには縦メンバ３３,３４の一方を横メンバ３２と同様に両側辺に溝部を有するメンバを用いればよい。 Although one vacuum heat insulation panel 1 is fixed to the housing 2 through the frame body by the above operation, the above operation is repeated when many vacuum heat insulation panels 1 are fixed continuously. In addition, although the example which can add the vacuum heat insulation panel 1 to an up-down direction was shown in the figure, in order to add to a horizontal direction, one of the vertical members 33 and 34 has a groove part on both sides similarly to the horizontal member 32. A member may be used.

真空断熱パネル１のフランジ部１１ａの部分は、厚み方向において真空部が存在しないため断熱効果におとる。しかしながら枠体３を構成する各メンバの溝部に前記フランジ部１１ａを挿入することで、真空による断熱効果よりは劣るが、従来に比較すると大幅な断熱効果の向上が認められる。 The portion of the flange portion 11a of the vacuum heat insulation panel 1 has a heat insulation effect because there is no vacuum portion in the thickness direction. However, by inserting the flange portion 11a into the groove portion of each member constituting the frame 3, the heat insulation effect by vacuum is inferior, but a significant improvement in heat insulation effect is recognized compared to the conventional case.

本発明に係る断熱構造は、建造物の断熱の他に家電製品、自動車、航空機など広い分野で利用できる。   The heat insulation structure according to the present invention can be used in a wide range of fields such as home appliances, automobiles, and aircrafts in addition to heat insulation of buildings.
