Description

本発明は、本発明は、建物の壁に真空断熱材を用いた断熱壁と、それを適用した建物および住宅に関するものである。   This invention relates to the heat insulation wall which used the vacuum heat insulating material for the wall of a building, and the building and house which applied it.

近年、地球温暖化抑制（地球環境保護）の観点より、家電製品や産業機器の省エネルギー化と並び住宅等の建物の省エネルギー化も取り組むべき重要な課題となっている。そのため、様々な断熱材の適用や各種断熱壁が提案されている（例えば、非特許文献１及び特許文献１参照）。   In recent years, from the viewpoint of suppressing global warming (protecting the global environment), energy savings for buildings such as houses as well as energy savings for home appliances and industrial equipment have become important issues. Therefore, various heat insulating materials and various heat insulating walls have been proposed (see, for example, Non-Patent Document 1 and Patent Document 1).

非特許文献１に示されているように、昭和５５年省エネルギー基準レベルの在来木造住宅（築２４年の木造在来軸組工法２階建て住宅）の２階天井及び１階床下の断熱改修を行った場合、天井では小屋裏の既存断熱を残し、その上に新規断熱材を吹き込み、また床では床下から根太間に断熱材を充填し根太下にも同様の断熱材の充填を行う。施工はそれぞれ作業員３名（約５時間）・監督１名、作業員５名（約１０時間）・監督２名で行い、約１６万円と約３７万円の費用がかかっている。   As shown in Non-Patent Document 1, the insulation of the second-floor ceiling and the first-floor floor of a conventional wooden house with a level of energy conservation standards in 1980 (24-year-old wooden conventional frame construction method 2-story house) In the case of the above, the existing heat insulation of the hut is left on the ceiling, and a new heat insulating material is blown on the ceiling. On the floor, the heat insulating material is filled from under the floor to the joists, and the same heat insulating material is filled under the joists. Construction is done by 3 workers (about 5 hours) and 1 supervisor, 5 workers (about 10 hours) and 2 supervisors, respectively, and costs about 160,000 yen and 370,000 yen.

図１６は、特許文献１により開示されている従来の断熱壁の概略断面図である。図１６に示すように、特許文献１における従来の断熱壁は、躯体α上にボード１０２を形成した下地１０１上に略台形状の胴縁１０３を複数本固定し、胴縁１０３上に片面粘着テープを貼着し、壁下地全面に現場発泡型の合成樹脂発泡体１０４を吹き付けると共に胴縁１０３間に空間１０５ができるように形成し、次に、片面粘着テープを剥すことにより胴縁１０３の表面を露出させ、胴縁１０３上に乾式壁材１０７を施工している。
齋藤宏昭ら、”昭和５５年省エネルギー基準レベルの在来木造住宅を対象とする実用的断熱改修方法の検証”、独立行政法人 建築研究所、２００６年 特開平７−１１７１７号公報 FIG. 16 is a schematic cross-sectional view of a conventional heat insulating wall disclosed in Patent Document 1. As shown in FIG. As shown in FIG. 16, the conventional heat insulating wall in Patent Document 1 has a plurality of substantially trapezoidal trunk edges 103 fixed on a base 101 on which a board 102 is formed on a housing α, and single-sided adhesive on the trunk edge 103. A tape is pasted, and an in-situ foam type synthetic resin foam 104 is sprayed on the entire surface of the wall base so that a space 105 is formed between the barrel edges 103, and then the single-sided adhesive tape is peeled off to remove the barrel edges 103. The surface is exposed, and a dry wall material 107 is constructed on the trunk edge 103.
Hiroaki Saito et al., “Verification of practical thermal insulation retrofit method for conventional wooden houses with energy conservation standard level in 1980”, Building Research Institute, Independent Administrative Agency, 2006 Japanese Patent Laid-Open No. 7-11717

しかしながら、実際の断熱改修（非特許文献１）では、２階天井の施工においては作業員３名（約５時間）・監督１名で約１６万円の費用を要し、１階床下の施工においては作業員５名（約１０時間）・監督２名で約３７万円の費用を要する。   However, in the actual insulation improvement (Non-Patent Document 1), the construction of the ceiling on the second floor requires about 160,000 yen for three workers (about 5 hours) and one supervisor. Costs about 370,000 yen for 5 workers (about 10 hours) and 2 supervisors.

また特許文献１による従来の断熱壁では、住宅駆体の断熱性能を向上させるため、下地１０１上に略台形状の胴縁１０３を複数本固定し、胴縁１０３上に片面粘着テープを貼着し、壁下地１０１全面に現場発泡型の合成樹脂発泡体１０４を吹き付けると共に胴縁１０３間に空間１０５ができるように形成する。次に、片面粘着テープを剥すことにより胴縁１０３の表面を露出させ、胴縁１０３の表面に貼付した粘着テープによって、胴縁１０３上に防水シート１０６と乾式壁材１０７を施工する。   Moreover, in the conventional heat insulation wall by patent document 1, in order to improve the heat insulation performance of a housing driving body, the several trapezoid trunk edge 103 is fixed on the base | substrate 101, and the single-sided adhesive tape is stuck on the trunk edge 103. FIG. Then, an in-situ foam type synthetic resin foam 104 is sprayed on the entire surface of the wall base 101 and a space 105 is formed between the trunk edges 103. Next, the surface of the trunk edge 103 is exposed by peeling the single-sided adhesive tape, and the waterproof sheet 106 and the dry wall material 107 are applied on the trunk edge 103 with the adhesive tape attached to the surface of the trunk edge 103.

このように、断熱改修については本格的な工事が伴い、簡易に高性能な断熱改修を行うことが困難である。   As described above, full-scale construction is involved in the heat insulation repair, and it is difficult to easily perform high-performance heat insulation repair.

本発明は、上記課題に鑑み、容易に施工可能で断熱性能が良好な断熱壁を提供することを目的とする。   An object of this invention is to provide the heat insulation wall which can be constructed easily and has favorable heat insulation performance in view of the said subject.

上記目的を達成するために、本発明の断熱壁は、室内空間を構成する面材と、前記面材の室内側の面に固定された複数の胴縁と、芯材を外被材で減圧密封して成り前記外被材の間に前記芯材がある芯材部が互いに隣接する前記胴縁と前記胴縁との間で前記面材の室内側の面に接触または近接するように配置された真空断熱材と、前記真空断熱材を室内側から覆い隠すように前記胴縁に固定されたボード材とからなり、前記胴縁が前記芯材部の厚み以上の厚みを有し、前記真空断熱材における前記外被材の間に前記芯材が無く対向する前記外被材同士が熱溶着された熱溶着部の一部のみが前記胴縁と前記ボード材との間に位置するものである。   In order to achieve the above object, the heat insulating wall of the present invention includes a face material constituting an indoor space, a plurality of trunk edges fixed to the indoor side surface of the face material, and a core material that is decompressed by an outer covering material. Sealed and arranged so that the core part having the core material between the jacket materials is in contact with or close to the indoor side surface of the face material between the trunk edge and the trunk edge adjacent to each other. And the board material fixed to the trunk edge so as to cover the vacuum insulation material from the indoor side, the trunk edge has a thickness equal to or greater than the thickness of the core part, In the vacuum heat insulating material, the core material is not provided between the jacket materials, and only a part of the heat-welded part where the facing jacket materials are heat-welded is positioned between the trunk edge and the board material. It is.

これにより、室内空間を構成する面材（既存壁または壁下地）の室内側の面の所定位置に複数の胴縁を固定し、次に、真空断熱材（芯材を外被材で減圧密封して成る断熱材）の芯材部（外被材の間に芯材がある部分）が互いに隣接する胴縁と胴縁との間で面材の室内側の面に接触または近接するように、且つ、熱溶着部（外被材の間に芯材が無く対向する外被材同士が溶着された部分）の一部のみが胴縁の室内側の面の少なくとも一部を覆うように、真空断熱材を配置（固定）し、次に、ボード材を、真空断熱材を室内側から覆い隠すように胴縁に固定することにより、現場発泡の発泡断熱材を用いることなく、容易に施工可能で断熱性能が良好な断熱壁を得ることができ、既存壁を断熱壁にする場合は、既存壁を解体する必要はなく、壁紙の張り替えに近いレベルで簡単に断熱強化を行うことができるため、工事期間・工事費用においても非常に有利となる効果が得られる。   As a result, a plurality of trunk edges are fixed at predetermined positions on the indoor side surface of the face material (existing wall or wall base) constituting the indoor space, and then the vacuum heat insulating material (the core material is vacuum-sealed with the jacket material) So that the core portion (the portion where the core material is between the jacket materials) is in contact with or close to the indoor side surface of the face material between the adjacent trunk edges. And only a part of the heat-welded portion (the portion where the opposite jacket materials are welded without the core material between the jacket materials) covers at least a part of the inner surface of the trunk edge, Easily install without using foam foam insulation material on the floor by placing (fixing) the vacuum insulation material and then fixing the board material to the trunk edge so as to cover the vacuum insulation material from the indoor side. It is possible to obtain a heat insulating wall that is possible and has good heat insulating performance, and if the existing wall is made into a heat insulating wall, there is no need to dismantle the existing wall, wallpaper It is possible to easily perform adiabatic reinforced with a level close to replacement, very advantageous and becomes effect can be obtained even in the construction period and construction cost.

また、真空断熱材はスチレンフォーム等の汎用の断熱材に比べて断熱性能が非常に優れているため、断熱材部分の厚みを薄くでき、その結果、断熱壁を薄くできる。また、真空断熱材を設ける面材を既存壁にする場合は、断熱壁とすることによる室内側への壁面の出っ張り寸法を小さくできるので、問題なく適用可能な範囲が広く実用的である。   Moreover, since the heat insulation performance is very excellent compared with general-purpose heat insulating materials such as styrene foam, the vacuum heat insulating material can reduce the thickness of the heat insulating material portion, and as a result, the heat insulating wall can be thinned. In addition, when the face material on which the vacuum heat insulating material is provided is an existing wall, the projecting dimension of the wall surface toward the indoor side by using the heat insulating wall can be reduced, so that the applicable range without problems is wide and practical.

また、ボード材を胴縁に固定した後は、真空断熱材の熱溶着部の一部を、胴縁とボード材とで挟んで固定できるので、ボード材を胴縁に固定する前の真空断熱材の固定を、ボード材を胴縁に固定するまでの仮固定にすることができ、ボード材を胴縁に固定する前の真空断熱材の胴縁または面材への固定に、時間の経過により固定または接着の機能が低下するような固定手段を用いることができ、固定手段の選択肢が多く、固定手段の選択によっては、作業性の向上やコスト低減が可能になる。   In addition, after fixing the board material to the body edge, a part of the heat-welded part of the vacuum insulation material can be sandwiched and fixed between the body edge and the board material, so the vacuum insulation before fixing the board material to the body edge The material can be fixed temporarily until the board material is fixed to the body edge, and time is required for fixing the vacuum insulation material to the body edge or face material before fixing the board material to the body edge. Thus, a fixing means that lowers the function of fixing or bonding can be used, and there are many options for the fixing means. Depending on the selection of the fixing means, workability can be improved and costs can be reduced.

また、胴縁が芯材部の厚み以上の厚みを有するので、ボード材が真空断熱材の芯材部により圧迫されることがない。これにより、ボード材を平面状態に施工することができる。また、ボード材による負荷が芯材部にかかりにくいため、外被材が損傷し難くなり真空断熱材の内圧上昇を低減することが可能となるため、長期間にわたって高断熱性能な断熱壁を維持することができる。   Moreover, since the trunk edge has a thickness equal to or greater than the thickness of the core material portion, the board material is not pressed by the core material portion of the vacuum heat insulating material. Thereby, a board | substrate material can be constructed in a plane state. In addition, since the load from the board material is hard to be applied to the core material part, it is difficult to damage the jacket material, and it is possible to reduce the increase in internal pressure of the vacuum heat insulating material, thus maintaining a heat insulating wall with high heat insulating performance for a long period of time. can do.

また、胴縁と芯材部の厚みの差を、真空断熱材（芯材部）の内圧が大気圧近くまで上昇して、芯材部が膨む場合の芯材部の厚みの増加分以上にすれば、真空断熱材（芯材部）の内圧が大気圧近くまで上昇して、芯材部が膨れ厚くなった時に、ボード材と芯材部との隙間で、芯材部の厚みの増加分を吸収でき、ボード材が芯材部により押されて室内側に膨らむ問題をなくすことが可能となる。   In addition, the difference in thickness between the trunk edge and the core part is equal to or greater than the increase in the thickness of the core part when the internal pressure of the vacuum heat insulating material (core part) rises to near atmospheric pressure and the core part expands. If the internal pressure of the vacuum heat insulating material (core material part) rises to near atmospheric pressure and the core material part swells and thickens, the gap between the board material and the core material part causes the thickness of the core material part to The increase can be absorbed, and the problem that the board material is pushed by the core member and swells indoors can be eliminated.

なお、面材と芯材部との隙間、またはボード材と芯材部との隙間は、１５ｍｍ以下であることが好ましく、上記隙間が１５ｍｍ以下であれば、隙間の空気の対流を抑えることができ、隙間の空気の対流による断熱壁の断熱性の悪化を抑えることができる。   The gap between the face material and the core material part or the gap between the board material and the core material part is preferably 15 mm or less. If the gap is 15 mm or less, convection of air in the gap can be suppressed. It is possible to suppress the deterioration of the heat insulating property of the heat insulating wall due to the convection of the air in the gap.

また、芯材部が面材とボード材と胴縁とによって形成される空間に位置し、熱溶着部の一部が胴縁の室内側の面の少なくとも一部を覆うように、真空断熱材を配置したので、胴縁がない部分における芯材部（真空断熱材の有効断熱部）が覆う面積の割合を大きくでき、高断熱性能の断熱壁を提供できる。   Further, the vacuum heat insulating material is provided so that the core material portion is located in a space formed by the face material, the board material, and the trunk edge, and a part of the heat welding portion covers at least a part of the interior side surface of the trunk edge. Therefore, the ratio of the area covered by the core portion (effective heat insulating portion of the vacuum heat insulating material) in the portion having no trunk edge can be increased, and a heat insulating wall with high heat insulating performance can be provided.

また、芯材部の厚み以上の厚みの複数の胴縁を面材の室内側の面に固定した後に、真空断熱材を配置するので、特に断熱壁を床に適用する場合は、断熱壁の施工時に、施工作業者が、胴縁を活用して芯材部に大きな負荷（体重など）をかけることなく、断熱壁を施工できる。   In addition, since the vacuum heat insulating material is arranged after fixing the plurality of trunk edges having a thickness equal to or greater than the thickness of the core material portion to the indoor side surface of the face material, particularly when the heat insulating wall is applied to the floor, At the time of construction, the construction worker can construct the heat insulation wall without applying a heavy load (such as weight) to the core part by utilizing the trunk edge.

本発明の断熱壁は、現場発泡の発泡断熱材を用いることなく、容易に施工可能で断熱性能が良好な断熱壁を得ることができ、既存壁を断熱壁にする場合は、既存壁を解体する必要はなく、壁紙の張り替えに近いレベルで簡単に断熱強化を行うことができるため、工事期間・工事費用においても非常に有利となる効果が得られる。   The heat insulating wall of the present invention can be easily constructed without using a foam heat insulating material that is foamed on site, and can obtain a heat insulating wall with good heat insulating performance. When an existing wall is used as a heat insulating wall, the existing wall is disassembled. There is no need to do this, and it is possible to easily reinforce the insulation at a level close to the replacement of the wallpaper.

また、断熱壁を薄くできる。また、真空断熱材を固定する面材を既存壁にする場合は、断熱壁とすることによる室内側への壁面の出っ張り寸法を小さくできるので、問題なく適用可能な範囲が広く実用的である。   Moreover, the heat insulating wall can be made thin. Moreover, when the face material which fixes a vacuum heat insulating material is used as an existing wall, since the protruding dimension of the wall surface to the indoor side by using the heat insulating wall can be reduced, the applicable range is wide and practical without problems.

また、ボード材を胴縁に固定する前の真空断熱材の固定を、ボード材を胴縁に固定するまでの仮固定にすることができ、ボード材を胴縁に固定する前の真空断熱材の固定に、時間の経過により固定または接着の機能が低下するような固定手段を用いることができ、固定手段の選択肢が多く、固定手段の選択によっては、作業性の向上やコスト低減が可能になる。   In addition, the vacuum insulation material before fixing the board material to the body edge can be temporarily fixed until the board material is fixed to the body edge, and the vacuum insulation material before fixing the board material to the body edge. Fixing means can be used for fixing the fixing or bonding function that degrades over time, and there are many options for fixing means, and depending on the choice of fixing means, workability can be improved and costs can be reduced. Become.

また、胴縁が芯材部の厚み以上の厚みを有するので、ボード材を平面状態に施工することができる。また、ボード材による負荷が芯材部にかかりにくいため、外被材が損傷し難くなり真空断熱材の内圧上昇を低減することが可能となるため、長期間にわたって高断熱性能な断熱壁を維持することができる。   Moreover, since a trunk edge has thickness more than the thickness of a core material part, a board | substrate material can be constructed in a plane state. In addition, since the load from the board material is hard to be applied to the core material part, it is difficult to damage the jacket material, and it is possible to reduce the increase in internal pressure of the vacuum heat insulating material, thus maintaining a heat insulating wall with high heat insulating performance for a long period of time. can do.

また、芯材部が面材とボード材と胴縁とによって形成される空間に位置し、熱溶着部の一部が胴縁の室内側の面の少なくとも一部を覆うように、真空断熱材を配置したので、胴縁がない部分における芯材部（真空断熱材の有効断熱部）が覆う面積の割合を大きくでき、高断熱性能の断熱壁を提供できる。   Further, the vacuum heat insulating material is provided so that the core material portion is located in a space formed by the face material, the board material, and the trunk edge, and a part of the heat welding portion covers at least a part of the interior side surface of the trunk edge. Therefore, the ratio of the area covered by the core portion (effective heat insulating portion of the vacuum heat insulating material) in the portion having no trunk edge can be increased, and a heat insulating wall with high heat insulating performance can be provided.

また、芯材部の厚み以上の厚みの複数の胴縁を面材の室内側の面に固定した後に、真空断熱材を配置するので、特に断熱壁を床に適用する場合は、断熱壁の施工時に、施工作業者が、胴縁を活用して芯材部に大きな負荷（体重など）をかけることなく、断熱壁を施工できる。   In addition, since the vacuum heat insulating material is arranged after fixing the plurality of trunk edges having a thickness equal to or greater than the thickness of the core material portion to the indoor side surface of the face material, particularly when the heat insulating wall is applied to the floor, At the time of construction, the construction worker can construct the heat insulation wall without applying a heavy load (such as weight) to the core part by utilizing the trunk edge.

請求項１の記載の断熱壁の発明は、室内空間を構成する面材と、前記面材の室内側の面に固定された複数の胴縁と、芯材を外被材で減圧密封して成り前記外被材の間に前記芯材がある芯材部が互いに隣接する前記胴縁と前記胴縁との間で前記面材の室内側の面に接触または近接するように配置された真空断熱材と、前記真空断熱材を室内側から覆い隠すように前記胴縁に固定されたボード材とからなり、前記胴縁が前記芯材部の厚み以上の厚みを有し、前記真空断熱材における前記外被材の間に前記芯材が無く対向する前記外被材同士が熱溶着された熱溶着部の一部のみが前記胴縁と前記ボード材との間に位置するものである。   The invention of the heat insulation wall according to claim 1 is that the face material constituting the indoor space, the plurality of trunk edges fixed to the indoor side surface of the face material, and the core material are sealed under reduced pressure with the jacket material. The vacuum is arranged so that the core part having the core material between the jacket materials is in contact with or close to the indoor side surface of the face material between the trunk edge and the trunk edge adjacent to each other. A heat insulating material and a board material fixed to the body edge so as to cover the vacuum heat insulating material from the indoor side, and the body edge has a thickness greater than or equal to the thickness of the core material part, and the vacuum heat insulating material In this case, only a part of the heat-welded portion where the facing covering materials are heat-welded without the core material between the covering materials is positioned between the trunk edge and the board material.

これにより、室内空間を構成する面材（既存壁または壁下地）の室内側の面の所定位置に複数の胴縁を固定し、次に、真空断熱材（芯材を外被材で減圧密封して成る断熱材）の芯材部（外被材の間に芯材がある部分）が互いに隣接する胴縁と胴縁との間で面材の室内側の面に接触または近接するように、且つ、熱溶着部（外被材の間に芯材が無く対向する外被材同士が溶着された部分）の一部のみが胴縁の室内側の面の少なくとも一部を覆うように、真空断熱材を配置（固定）し、次に、ボード材を、真空断熱材を室内側から覆い隠すように胴縁に固定することにより、現場発泡の発泡断熱材を用いることなく、容易に施工可能で断熱性能が良好な断熱壁を得ることができ、既存壁を断熱壁にする場合は、既存壁を解体する必要はなく、壁紙の張り替えに近いレベルで簡単に断熱強化を行うことができるため、工事期間・工事費用においても非常に有利となる効果が得られる。   As a result, a plurality of trunk edges are fixed at predetermined positions on the indoor side surface of the face material (existing wall or wall base) constituting the indoor space, and then the vacuum heat insulating material (the core material is vacuum-sealed with the jacket material) So that the core portion (the portion where the core material is between the jacket materials) is in contact with or close to the indoor side surface of the face material between the adjacent trunk edges. And only a part of the heat-welded portion (the portion where the opposite jacket materials are welded without the core material between the jacket materials) covers at least a part of the inner surface of the trunk edge, Easily install without using foam foam insulation material on the floor by placing (fixing) the vacuum insulation material and then fixing the board material to the trunk edge so as to cover the vacuum insulation material from the indoor side. It is possible to obtain a heat insulating wall that is possible and has good heat insulating performance, and if the existing wall is made into a heat insulating wall, there is no need to dismantle the existing wall, wallpaper It is possible to easily perform adiabatic reinforced with a level close to replacement, very advantageous and becomes effect can be obtained even in the construction period and construction cost.

In addition, when the face material on which the vacuum heat insulating material is provided is an existing wall, the projecting dimension of the wall surface toward the indoor side by using the heat insulating wall can be reduced, so that the applicable range without problems is wide and practical.

また、ボード材を胴縁に固定した後は、真空断熱材の熱溶着部の一部を、胴縁とボード材とで挟んで固定できるので、ボード材を胴縁に固定する前の真空断熱材の固定を、ボード材を胴縁に固定するまでの仮固定にすることができ、ボード材を胴縁に固定する前の真空断熱材の胴縁または面材への固定に、時間の経過により固定または接着の機能が低下するような固定手段を用いることができ、固定手段の選択肢が多く、固定手段の選択によっては、作業性の向上やコスト低減が可能になる。   In addition, after fixing the board material to the body edge, a part of the heat-welded part of the vacuum insulation material can be sandwiched and fixed between the body edge and the board material, so the vacuum insulation before fixing the board material to the body edge The material can be fixed temporarily until the board material is fixed to the body edge, and time is required for fixing the vacuum insulation material to the body edge or face material before fixing the board material to the body edge. Thus, a fixing means that lowers the function of fixing or bonding can be used, and there are many options for the fixing means. Depending on the selection of the fixing means, workability can be improved and costs can be reduced.

また、胴縁と芯材部の厚みの差を、真空断熱材（芯材部）の内圧が大気圧近くまで上昇して、芯材部が膨む場合の芯材部の厚みの増加分以上にすれば、真空断熱材（芯材部）の内圧が大気圧近くまで上昇して、芯材部が膨れ厚くなった時に、ボード材と芯材部との隙間で、芯材部の厚みの増加分を吸収でき、ボード材が芯材部により押されて室内側に膨らむ問題をなくすことが可能となる。   In addition, the difference in thickness between the trunk edge and the core part is equal to or greater than the increase in the thickness of the core part when the internal pressure of the vacuum heat insulating material (core part) rises to near atmospheric pressure and the core part expands. If the internal pressure of the vacuum heat insulating material (core material part) rises to near atmospheric pressure and the core material part swells and thickens, the gap between the board material and the core material part causes the thickness of the core material part to The increase can be absorbed, and the problem that the board material is pushed by the core member and swells indoors can be eliminated.

なお、面材と芯材部との隙間、またはボード材と芯材部との隙間は、１５ｍｍ以下であることが好ましく、上記隙間が１５ｍｍ以下であれば、隙間の空気の対流を抑えることができ、隙間の空気の対流による断熱壁の断熱性の悪化を抑えることができる。   The gap between the face material and the core material part or the gap between the board material and the core material part is preferably 15 mm or less. If the gap is 15 mm or less, convection of air in the gap can be suppressed. It is possible to suppress the deterioration of the heat insulating property of the heat insulating wall due to the convection of the air in the gap.

また、芯材部が面材とボード材と胴縁とによって形成される空間に位置し、熱溶着部の一部が胴縁の室内側の面の少なくとも一部を覆うように、真空断熱材を配置したので、胴縁がない部分における芯材部（真空断熱材の有効断熱部）が覆う面積の割合を大きくでき、高断熱性能の断熱壁を提供できる。   Further, the vacuum heat insulating material is provided so that the core material portion is located in a space formed by the face material, the board material, and the trunk edge, and a part of the heat welding portion covers at least a part of the interior side surface of the trunk edge. Therefore, the ratio of the area covered by the core portion (effective heat insulating portion of the vacuum heat insulating material) in the portion having no trunk edge can be increased, and a heat insulating wall with high heat insulating performance can be provided.

また、芯材部の厚み以上の厚みの複数の胴縁を面材の室内側の面に固定した後に、真空断熱材を配置するので、特に断熱壁を床に適用する場合は、断熱壁の施工時に、施工作業者が、胴縁を活用して芯材部に大きな負荷（体重など）をかけることなく、断熱壁を施工できる。   In addition, since the vacuum heat insulating material is arranged after fixing the plurality of trunk edges having a thickness equal to or greater than the thickness of the core material portion to the indoor side surface of the face material, particularly when the heat insulating wall is applied to the floor, At the time of construction, the construction worker can construct the heat insulation wall without applying a heavy load (such as weight) to the core part by utilizing the trunk edge.

請求項２の記載の断熱壁の発明は、請求項１に記載の発明における前記真空断熱材として、熱溶着層同士が対向するガスバリア性でフレキシブルな前記外被材の間に、板状の前記芯材が配置されて、前記外被材の間に前記芯材が無い部分の前記外被材同士を密着させて、前記密着した前記外被材同士を熱溶着してなり、前記外被材同士が密着する全ての部分の前記外被材同士が熱溶着されている真空断熱材を用いたものである。   The invention of the heat insulation wall according to claim 2 is the plate-like, as the vacuum heat insulation material according to the invention of claim 1, between the gas barrier property and flexible outer covering material in which the heat-welding layers face each other. A core material is disposed, the jacket materials in a portion where the core material does not exist are closely adhered to each other between the jacket materials, and the adhered jacket materials are thermally welded to each other, and the jacket material A vacuum heat insulating material is used in which the jacket materials of all the parts that are in close contact with each other are heat-welded.

これにより、請求項１に記載の発明の作用効果に加えて、本発明に用いる真空断熱材は、外被材同士が密着する全ての部分の外被材同士が熱溶着されている真空断熱材であり、外被材同士が密着する部分は外被材の間に芯材がある部分の近傍まで熱溶着されているので、外周部分の外被材同士のみ熱溶着された真空断熱材に比べて熱溶着部の幅が広く、それにより胴縁と熱溶着部との接触面積を広くできるため、胴縁と熱溶着部との接触面積を広くして胴縁とボード材とによって真空断熱材をより確実に固定できる。   Thereby, in addition to the effect of the invention according to claim 1, the vacuum heat insulating material used in the present invention is a vacuum heat insulating material in which all the outer covering materials in which the outer covering materials are in close contact with each other are thermally welded. Since the portion where the jacket materials are in close contact with each other is thermally welded to the vicinity of the portion where the core material is between the jacket materials, compared to the vacuum heat insulating material where only the outer jacket materials are thermally welded The width of the heat-welded part is wide, so that the contact area between the body edge and the heat-welded part can be widened. Can be fixed more securely.

また、熱溶着部が胴縁（とボード材）から受ける押圧力を広い接触面積で受けると、胴縁（とボード材）と熱溶着部との接触部分における単位面積あたりの押圧力が小さくなるため、胴縁（とボード材）と熱溶着部との接触面積を広くして胴縁（とボード材）による真空断熱材の熱溶着部の損傷の可能性を小さくすることができ、外被材同士が密着する部分は外被材の間に芯材がある部分の近傍まで熱溶着されているので、胴縁（とボード材）と熱溶着部との接触で熱溶着部が損傷したり、真空断熱材を芯材部から所定間隔以上離れた熱溶着部を貫通して胴縁に突き刺さる部材で固定したり、ボード材をボード材と芯材部から所定間隔以上離れた熱溶着部と胴縁を貫通して面材に突き刺さる部材で固定した場合でも、熱溶着部の損傷部分や貫通孔ができた部分の芯材側に充分な幅の熱溶着部が残るので、真空断熱材の断熱性能悪化の可能性が少なく、断熱性能の信頼性が高い断熱壁になる。   Moreover, if the thermal welding part receives the pressing force received from the trunk edge (and the board material) with a wide contact area, the pressing force per unit area at the contact part between the trunk edge (and the board material) and the thermal welding part becomes small. Therefore, the contact area between the body edge (and board material) and the heat-welded portion can be widened to reduce the possibility of damage to the heat-welded portion of the vacuum heat insulating material due to the body edge (and board material). The part where the materials are in close contact is heat welded to the vicinity of the part where the core material is between the jacket materials, so the heat welded part may be damaged by contact between the body edge (and board material) and the heat welded part. The vacuum heat insulating material is fixed with a member that penetrates the thermal welding portion that is spaced apart from the core material portion by a predetermined distance and penetrates the trunk edge, or the board material is separated from the board material and the core material portion by a predetermined distance or more. Even if it is fixed with a member that penetrates the body edge and penetrates the face material, Since the heat seal parts of the wide enough core side portion could holes remains, less likelihood of insulation performance deterioration of the vacuum heat insulating material, the reliability of the insulation performance is high insulating wall.

また、外被材同士が密着する部分は外被材の間に芯材がある部分の近傍まで熱溶着されているので、壁の厚みに垂直な方向で外被材の間に芯材がある部分と胴縁との間隔を狭くしても、外被材の損傷で真空断熱材の断熱性能が悪化する可能性が少なく、そのため、芯材部（外被材の間に芯材がある部分）と胴縁との間隔を狭くして断熱壁における真空断熱材の有効断熱部である芯材部の被覆率を高めて断熱壁の全体の断熱性能を高めることができる。   In addition, since the portion where the jacket materials are in close contact with each other is thermally welded to the vicinity of the portion where the core material is between the jacket materials, there is a core material between the jacket materials in the direction perpendicular to the wall thickness. Even if the gap between the part and the body edge is narrowed, there is little possibility that the heat insulation performance of the vacuum heat insulating material will be deteriorated due to damage to the jacket material, and therefore the core part (the part where the core material is between the jacket materials) ) And the body edge can be narrowed to increase the covering ratio of the core part which is an effective heat insulating part of the vacuum heat insulating material in the heat insulating wall, thereby improving the overall heat insulating performance of the heat insulating wall.

The material is used.

これにより、請求項２に記載の発明の作用効果に加えて、外被材にピンホールができたり外被材が破損（破袋）したりして芯材を減圧密封した空間（芯材部）の内圧が上昇して断熱性能が悪化する場合でも、ピンホールや破損（破袋）の影響を直接受ける特定の芯材を減圧密封した空間（芯材部）内の圧力が高くなって断熱性能が悪化するだけで、断熱性能の悪化が真空断熱材全体に広がらず、真空断熱材としての断熱性の悪化は小さくできる効果が得られる。また、一つの真空断熱材を配置（固定）する作業で、複数の芯材部を配置（固定）できる。   Thereby, in addition to the function and effect of the invention according to claim 2, the space (core material portion) in which the core material is sealed under reduced pressure by forming a pinhole in the jacket material or damaging (breaking the bag) the jacket material ) Increases the pressure inside the space (core material part) where the specific core material that is directly affected by pinholes and breakage (bag breakage) is sealed under reduced pressure Only the performance deteriorates, and the deterioration of the heat insulation performance does not spread to the entire vacuum heat insulating material, and the effect of reducing the deterioration of the heat insulating property as the vacuum heat insulating material is obtained. In addition, a plurality of core parts can be arranged (fixed) in the operation of arranging (fixing) one vacuum heat insulating material.

ここで、略接触とは、ほとんど接触している状態のことであり、目視で接触していることが確認できる程度の接触状態を指す。   Here, “substantially contact” refers to a state of almost contact, and refers to a contact state to the extent that it can be confirmed visually.

本実施の形態における内壁２は、室内側からコの字形の金属製の固定具であるタッカーやネジや釘を打ち込み可能な材料からなり所定の厚みを有するものである。もし、内壁２の面材が充分な厚みを有しておらず、タッカー３または釘７が内壁２の面材を貫通する場合は、タッカー３と釘７を打ち込む位置を内壁２の面材の裏側（反室内側）に柱がある部分にすることが好ましい。   The inner wall 2 in the present embodiment is made of a material capable of driving a tucker, a screw, or a nail, which is a U-shaped metal fixture, from the indoor side and has a predetermined thickness. If the face material of the inner wall 2 does not have a sufficient thickness and the tucker 3 or the nail 7 penetrates the face material of the inner wall 2, the position where the tacker 3 and the nail 7 are driven is set to the position of the face material of the inner wall 2. It is preferable that the column has a column on the back side (inside of the room).

本実施の形態では、ポリスチレン、ポリプロピレン、ポリエチレン、ウレタン等による発泡断熱材からなる胴縁６を用いているが、コルク等、熱伝導し難くタッカーやネジや釘を打ち込み可能な材料で構成された他の胴縁を用いても構わない。   In this embodiment, the body edge 6 made of a foam heat insulating material made of polystyrene, polypropylene, polyethylene, urethane or the like is used, but it is made of a material such as cork that is hard to conduct heat and can be driven with tucker, screws, and nails. Other trunk edges may be used.

真空断熱材４は、熱溶着層１０同士が対向するガスバリア性でフレキシブルな長方形の外被材１１の間に、ガラス繊維などの無機繊維の積層体からなる厚さが８ｍｍ前後の長方形の板状の二つの芯材１２が、厚み方向に略垂直な方向に互いに所定間隔離して配置されて、二つの芯材１２のそれぞれが独立した空間内に位置するように、外被材１１の間に芯材１２がない部分の外被材１１同士（隣接する芯材１２と芯材１２との間の外被材１１同士を含む）を密着させて、密着した外被材１１同士を熱溶着して熱溶着部１６を形成してなり、外被材１１同士が密着する全ての部分の外被材１１同士が熱溶着されている真空断熱材４である。   The vacuum heat insulating material 4 is a rectangular plate having a thickness of about 8 mm made of a laminated body of inorganic fibers such as glass fibers between gas barrier and flexible rectangular covering materials 11 facing the heat-welding layers 10. The two core members 12 are arranged in a direction substantially perpendicular to the thickness direction and separated from each other by a predetermined distance, and the two core members 12 are positioned between the jacket members 11 so that each of the two core members 12 is located in an independent space. A portion of the jacket material 11 in the absence of the core material 12 (including the jacket materials 11 between the adjacent core material 12 and the core material 12) is brought into close contact, and the tightly covered jacket materials 11 are thermally welded together. Thus, the heat insulating portion 16 is formed, and the vacuum insulating material 4 is formed by heat-welding the outer covering materials 11 of all the portions where the outer covering materials 11 are in close contact with each other.

また、真空断熱材４における外被材１１の間に芯材１２が無く対向する外被材１１同士が熱溶着された熱溶着部１６の一部のみが胴縁６とボード材８との間に位置している。   Further, there is no core material 12 between the jacket materials 11 in the vacuum heat insulating material 4, and only a part of the heat welded portion 16 in which the facing jacket materials 11 are thermally welded is between the trunk edge 6 and the board material 8. Is located.

また、真空断熱材４における互いに隣接する芯材部１５と芯材部１５との間の外被材１１同士が熱溶着された熱溶着部１６の一部が胴縁６とボード材８との間に位置している。   Further, a part of the heat-welded portion 16 in which the jacket materials 11 between the core material portions 15 adjacent to each other in the vacuum heat insulating material 4 are heat-welded is formed between the trunk edge 6 and the board material 8. Located between.

また、真空断熱材４は、芯材部１５から所定間隔以上離れた熱溶着部１６を貫通して胴縁６に突き刺さるタッカー３で固定されている。   Further, the vacuum heat insulating material 4 is fixed by a tucker 3 that penetrates the thermal welding portion 16 that is separated from the core portion 15 by a predetermined distance or more and pierces the trunk edge 6.

なお、胴縁６を貫通して内壁２に突き刺さって胴縁６を内壁２の室内側の面に固定するタッカー５の代わりに、内壁２の室内側の面に胴縁６を固定する接着剤を用いてもよいが、その場合は、真空断熱材４を固定するためのタッカー３として、芯材部１５から所定間隔以上離れた熱溶着部１６と胴縁６を貫通して内壁２に突き刺さるものを用いることが好ましい。   Instead of the tucker 5 that penetrates the trunk edge 6 and penetrates the inner wall 2 to fix the trunk edge 6 to the indoor surface of the inner wall 2, an adhesive that fixes the trunk edge 6 to the indoor surface of the inner wall 2. However, in that case, as the tucker 3 for fixing the vacuum heat insulating material 4, the inner wall 2 is pierced through the heat welding portion 16 and the trunk edge 6 which are separated from the core material portion 15 by a predetermined distance or more. It is preferable to use one.

また、ボード材８は、ボード材８と芯材部１５から所定間隔以上離れた熱溶着部１６と胴縁６を貫通して内壁２に突き刺さる釘７で固定されている。   Further, the board material 8 is fixed by a nail 7 that penetrates the inner wall 2 through the thermal welding portion 16 and the trunk edge 6 that are separated from the board material 8 and the core material portion 15 by a predetermined distance or more.

本実施の形態の真空断熱材４の芯材１２の厚みは８ｍｍ前後であるが、８ｍｍ前後の厚みに限定するものではなく、厚みは３ｍｍから１０ｍｍでもよい。芯材１２の厚みが薄いほど、芯材１２の周囲に外被材１１の皺ができにくく、外被材１１同士を芯材１２の近くまで容易に熱溶着できるが、芯材１２の厚みが薄い分、真空断熱材４の断熱性能は低下する。逆に、芯材１２の厚みが厚いほど、芯材１２の周囲に外被材１１の皺ができやすく、外被材１１同士を芯材１２の近くまで熱溶着することが難しくなるが、芯材１２の厚みが厚い分、真空断熱材４の断熱性能は高くなる。   Although the thickness of the core material 12 of the vacuum heat insulating material 4 of this embodiment is about 8 mm, the thickness is not limited to about 8 mm, and the thickness may be 3 mm to 10 mm. As the core material 12 is thinner, the outer cover material 11 is less likely to be wrinkled around the core material 12, and the outer cover materials 11 can be easily heat-sealed to the vicinity of the core material 12. The heat insulation performance of the vacuum heat insulating material 4 is reduced by the thin amount. Conversely, the thicker the core material 12, the easier it is for the outer cover material 11 to crease around the core material 12, making it difficult to thermally weld the outer cover materials 11 to the vicinity of the core material 12. Since the thickness of the material 12 is thick, the heat insulation performance of the vacuum heat insulating material 4 is increased.

芯材１２は、繊維の長手方向が真空断熱材４（芯材１２）の厚み方向（伝熱方向）に対して略垂直になっている無機繊維集合体を所定厚みになるように積層したものをバインダーを用いずに無機繊維同士の接触点が架橋部とならずに圧縮時の形状を保持できるよう所定の加熱加圧条件で加熱加圧成形したものを使用している。繊維の長手方向が厚み方向に対して略垂直になるように抄造法で成形したものや、繊維の長手方向が厚み方向に対して略垂直になっている無機繊維集合体を所定厚みになるように積層したものを無機バインダーを用いて成形したもの、繊維の長手方向が厚み方向に対して略垂直になっている無機繊維集合体を所定厚みになるように積層したものに水または酸性の水溶液を噴霧して無機繊維からの溶出物を無機繊維同士の接触点に集めて成形したもの、バインダーの働きをする無機粉体を無機繊維に混合して成形したものでも構わないが、本実施の形態の芯材１２よりは、断熱性能が劣る。   The core material 12 is formed by laminating inorganic fiber aggregates in which the longitudinal direction of the fibers is substantially perpendicular to the thickness direction (heat transfer direction) of the vacuum heat insulating material 4 (core material 12) so as to have a predetermined thickness. The material used is heated and pressed under predetermined heating and pressing conditions so that the contact point between the inorganic fibers does not become a cross-linked portion without using a binder and the shape during compression can be maintained. What is formed by a paper making method so that the longitudinal direction of the fiber is substantially perpendicular to the thickness direction, or an inorganic fiber aggregate in which the longitudinal direction of the fiber is substantially perpendicular to the thickness direction so as to have a predetermined thickness Water or an acidic aqueous solution formed by laminating an inorganic fiber assembly formed by using an inorganic binder, and laminating an inorganic fiber assembly in which the longitudinal direction of the fibers is substantially perpendicular to the thickness direction to a predetermined thickness The eluate from the inorganic fibers may be collected by spraying at a contact point between the inorganic fibers and molded, or the inorganic powder acting as a binder may be mixed with the inorganic fibers and molded. The heat insulation performance is inferior to the core material 12 in the form.

また、無機材料からなる芯材の方が、有機材料からなる芯材よりも、ガスの発生量が少ないという点で有利であり、繊維材料からなる芯材の方が、粒や粉からなる芯材よりも、製造時や真空断熱材または断熱壁の廃棄の取り扱いの点で有利である。   In addition, a core made of an inorganic material is advantageous in that it generates less gas than a core made of an organic material, and a core made of a fiber material is more advantageous than a core made of particles or powder. It is more advantageous than the material in terms of manufacturing and disposal of the vacuum heat insulating material or the heat insulating wall.

本実施の形態における外被材１１は、図２に示すように、熱溶着層１０と保護層１３との間にガスバリア層１４を有するラミネートフィルムからなり、芯材１２側の熱溶着層１０としてはポリエチレン等が用いられ、ガスバリア層１４としては１０μｍ以下のアルミ箔が用いられ、ガスバリア層１４の外側の保護層１３としてはナイロンまたはポエチレンテレフタレート等が用いられる。なお、保護層１３はナイロンまたはポエチレンテレフタレートからなるフィルムを二層重ねて構成することもある。なお、ガスバリア層１４としては、アルミ箔等の金属箔の他に、樹脂フィルムの表面に蒸着または塗布または蒸着と塗布の組み合わせによりガスバリア層を形成したものでも構わない。   As shown in FIG. 2, the jacket material 11 in the present embodiment is made of a laminate film having a gas barrier layer 14 between the thermal welding layer 10 and the protective layer 13, and is used as the thermal welding layer 10 on the core material 12 side. Polyethylene or the like is used, aluminum foil of 10 μm or less is used as the gas barrier layer 14, and nylon or polyethylene terephthalate is used as the protective layer 13 outside the gas barrier layer 14. The protective layer 13 may be formed by stacking two layers of nylon or polyethylene terephthalate. In addition to the metal foil such as an aluminum foil, the gas barrier layer 14 may be one in which a gas barrier layer is formed on the surface of the resin film by vapor deposition or coating or a combination of vapor deposition and coating.

真空断熱材４は、内面に熱溶着層１０を有するガスバリア性のラミネートフィルムからなる外被材１１内に二つの芯材１２を厚み方向に略垂直な方向に互いに所定間隔離して配置して例えば０．１Ｔｏｒｒ以下の減圧空間内において減圧密封した後、外被材１１の外圧を大気圧にして外被材１１の外圧と内圧との差圧で外被材１１の間に芯材１２がない部分の外被材１１同士を密着させ、前記差圧で外被材１１同士が密着している部分に熱溶着層１０が溶融するのに必要な熱を非接触で加えて、密着している外被材１１同士を熱溶着する製造方法により得られる。   The vacuum heat insulating material 4 is formed by disposing two core materials 12 in a direction substantially perpendicular to the thickness direction and separated from each other by a predetermined distance in an outer cover material 11 made of a gas barrier laminate film having a heat welding layer 10 on the inner surface. After sealing under reduced pressure in a reduced pressure space of 0.1 Torr or less, the outer pressure of the jacket material 11 is set to atmospheric pressure, and there is no core material 12 between the jacket materials 11 due to the differential pressure between the outer pressure and the inner pressure of the jacket material 11. The portions of the jacket material 11 are brought into close contact with each other, and the heat necessary for the thermal welding layer 10 to melt is applied in a non-contact manner to the portion where the jacket materials 11 are in close contact with each other by the differential pressure. It is obtained by a manufacturing method in which the jacket materials 11 are thermally welded together.

ここで、減圧空間内において外被材１１内に芯材１２を減圧密封する工程は、例えば０．１Ｔｏｒｒ以下に減圧された真空包装機の減圧チャンバー内で、芯材１２が挿入された袋状の外被材１１の開口部を、一対の熱溶着バーで挟んで加熱加圧により熱溶着するものであっても、真空包装機の減圧チャンバー内で、芯材１２を覆う二枚の外被材１１の外周部同士を全周にわたって一対の熱溶着バーで挟んで加熱加圧により熱溶着するものであっても構わない。   Here, the step of vacuum-sealing the core material 12 in the jacket material 11 in the decompression space is, for example, a bag-like shape in which the core material 12 is inserted in a vacuum chamber of a vacuum packaging machine whose pressure is reduced to 0.1 Torr or less. Even if the opening of the outer cover material 11 is sandwiched between a pair of heat welding bars and heat-welded by heating and pressurization, the two outer coverings covering the core material 12 in the vacuum chamber of the vacuum packaging machine The outer peripheral portions of the material 11 may be sandwiched between a pair of heat welding bars over the entire circumference and thermally welded by heat and pressure.

また、外被材１１内に芯材１２を減圧密封する工程と、外被材１１の外圧を大気圧にして外被材１１の外圧と内圧との差圧で密着している外被材１１同士を熱溶着する工程とを、内部空間の真空排気と真空開放が可能なチャンバー内で行っても良いし、減圧空間内において外被材１１内に芯材１２を減圧密封したものを、減圧空間から取り出すことにより、外被材１１の外圧を大気圧にしても良い。   In addition, the core material 12 is sealed under reduced pressure in the outer cover material 11, and the outer cover material 11 is in close contact with the pressure difference between the external pressure and the internal pressure of the outer cover material 11 by setting the external pressure of the outer cover material 11 to atmospheric pressure. The step of heat-welding each other may be performed in a chamber in which the internal space can be evacuated and opened, or the core material 12 sealed in the outer cover material 11 in a reduced pressure space under reduced pressure. By taking out from the space, the external pressure of the jacket material 11 may be set to atmospheric pressure.

また、非接触で加える熱溶着層１０が溶融するのに必要な熱は、ヒータの輻射熱と周囲の温度とすることができ、また、非接触で加える熱溶着層１０が溶融するのに必要な熱は、外被材１１全体を加熱するものであっても構わない。   Further, the heat necessary for melting the heat welding layer 10 applied in a non-contact manner can be the radiant heat of the heater and the ambient temperature, and the heat welding layer 10 applied in a non-contact manner is necessary for melting. The heat may heat the entire jacket material 11.

また、真空断熱材４の外周にできる外被材１１の外周部同士が熱溶着された外周ヒレ部は、外周ヒレ部の幅が必要以上に広い場合は、芯材１２の周囲に所定幅の外被材１１同士が熱溶着された熱溶着部が残るように切り落としている。このとき、真空断熱材４の外周ヒレ部の四つの角が、作業者や他の部材（特に他の真空断熱材４）を傷つけないように、真空断熱材４の外周ヒレ部の四つの角を丸くすることが好ましい。   Moreover, the outer periphery fin part by which the outer peripheral parts of the jacket material 11 which can be made into the outer periphery of the vacuum heat insulating material 4 were heat-welded mutually has a predetermined width around the core material 12 when the width of the outer peripheral fin part is larger than necessary. It cuts off so that the heat welding part in which the jacket materials 11 were heat-welded may remain. At this time, the four corners of the peripheral fin portion of the vacuum heat insulating material 4 are not damaged by the four corners of the peripheral fin portion of the vacuum heat insulating material 4 so as to damage an operator or other members (particularly the other vacuum heat insulating material 4). Is preferably rounded.

また、真空断熱材４は、図３に示すように、外被材１１（熱溶着層１０）の間に芯材１２がある芯材部１５と、外被材１１（熱溶着層１０）の間に芯材１２が無く外被材１１同士が熱溶着された熱溶着部１６とを有しており、本実施の形態で用いる真空断熱材４は、芯材部１５が、縦方向に長い長方形で横方向に二つ並んでおり、熱溶着部１６が、二つの芯材部１５の間に位置する幅約２７ｍｍの芯材間熱溶着部１７と、真空断熱材４の外周ヒレ部（二つの芯材部１５及び芯材間熱溶着部１７の外周）に位置する幅約２１ｍｍの外周熱溶着部１８とからなる。   In addition, as shown in FIG. 3, the vacuum heat insulating material 4 includes a core material portion 15 having a core material 12 between a jacket material 11 (thermal welding layer 10), and a jacket material 11 (thermal welding layer 10). The vacuum insulating material 4 used in the present embodiment has a long core member 15 in the longitudinal direction. Two rectangular welds are arranged in the lateral direction, and the heat welded portion 16 includes an inter-core heat welded portion 17 having a width of about 27 mm located between the two core material portions 15 and an outer peripheral fin portion ( The outer peripheral heat welded portion 18 having a width of about 21 mm is located on the outer periphery of the two core material portions 15 and the inter-core heat welded portion 17.

本実施の形態で用いる真空断熱材４は、芯材部１５が横方向に二つ並んでいるものであるが、これに限らず、芯材部１５が横方向に三つ以上並んでいるものでも、芯材部１５が縦方向に二つ以上並んでいるものでも、芯材部１５が横方向と縦方向に複数列複数段碁盤目状に配置されているものでも構わない。また、本実施の形態で用いる真空断熱材４は、一種類であるが、複数種類の真空断熱材を組み合わせたり、芯材部が一つの真空断熱材を組み合わせても構わない。   The vacuum heat insulating material 4 used in the present embodiment is one in which two core parts 15 are arranged in the horizontal direction, but is not limited to this, and three or more core parts 15 are arranged in the horizontal direction. However, two or more core members 15 may be arranged in the vertical direction, or the core members 15 may be arranged in a plurality of rows and columns in a horizontal direction and a vertical direction. Moreover, although the vacuum heat insulating material 4 used by this Embodiment is one type, you may combine several types of vacuum heat insulating materials or may combine a vacuum heat insulating material with one core material part.

本実施の形態では、芯材間熱溶着部１７の幅を約２７ｍｍとしと外周熱溶着部１８の幅を約２１ｍｍとしているが、１６ｍｍ〜３０ｍｍであれば良く、芯材１２または芯材部１５の厚みが厚くなるほど、芯材間熱溶着部１７と外周熱溶着部１８の幅を広くする必要があり、芯材間熱溶着部１７と外周熱溶着部１８の幅を狭くするほど、断熱壁１における芯材部１５の占める割合が大きくなって断熱壁１の断熱性能が向上するが、外周熱溶着部１８の端または熱溶着部１６（芯材間熱溶着部１７と外周熱溶着部１８）を貫通する固定用の部材によってできた貫通孔から外気が芯材１２を密閉する空間に侵入して時間の経過によって断熱壁１（または真空断熱材４）の断熱性能が低下する可能性が高くなる。逆に芯材間熱溶着部１７と外周熱溶着部１８の幅を広くするほど、断熱壁１における芯材部１５の占める割合が小さくなって断熱壁１の断熱性能が低下するが、外周熱溶着部１８の端または熱溶着部１６（芯材間熱溶着部１７と外周熱溶着部１８）を貫通する固定用の部材によってできた貫通孔から外気が芯材１２を密閉する空間に侵入して時間の経過によって断熱壁１（または真空断熱材４）の断熱性能が低下する可能性が低くなる。   In the present embodiment, the width of the core-to-core heat welded portion 17 is set to about 27 mm and the width of the outer peripheral heat welded portion 18 is set to about 21 mm, but may be 16 mm to 30 mm, and may be the core material 12 or the core material portion 15. It is necessary to increase the width of the core-to-core heat welded portion 17 and the outer periphery heat-welded portion 18 as the thickness of the heat-insulating wall increases. 1, the heat insulation performance of the heat insulating wall 1 is improved, but the end of the outer peripheral heat welded portion 18 or the heat welded portion 16 (inter-core heat welded portion 17 and the outer peripheral heat welded portion 18 There is a possibility that outside air will enter the space that seals the core material 12 from the through-hole formed by the fixing member that passes through the fixing member, and the heat insulation performance of the heat insulation wall 1 (or the vacuum heat insulation material 4) may deteriorate with the passage of time. Get higher. Conversely, the wider the width of the inter-core heat welded portion 17 and the outer peripheral heat welded portion 18, the smaller the proportion of the core material portion 15 in the heat insulating wall 1 and the heat insulating performance of the heat insulating wall 1 decreases. The outside air enters the space that seals the core material 12 through the end of the welded portion 18 or the through hole formed by the fixing member that penetrates the heat welded portion 16 (inter-core heat welded portion 17 and the outer peripheral heat welded portion 18). Thus, the possibility that the heat insulation performance of the heat insulation wall 1 (or the vacuum heat insulating material 4) is lowered with the passage of time is reduced.

以下、断熱改修部位となる既存の建物の内壁２を本実施の形態の断熱壁１にする手順を、図４から図１３を参照しながら説明する。   Hereinafter, the procedure of making the inner wall 2 of the existing building which becomes the heat insulation renovation site into the heat insulation wall 1 of the present embodiment will be described with reference to FIGS. 4 to 13.

まず、図４と図９に示すように、室内空間を構成する面材で断熱改修部位となる既存の建物の内壁２の室内側の面の上下の縁に、上下の縁に合わせて横方向（左右方向）に長く真空断熱材４の芯材部１５と同じ厚みか芯材部１５より若干厚い厚みで、幅が約１５ｍｍの発泡断熱材からなる胴縁６を配置して、胴縁６を貫通して内壁２に突き刺さるタッカー５で固定する。   First, as shown in FIG. 4 and FIG. 9, the horizontal direction is aligned with the upper and lower edges of the indoor side surface of the inner wall 2 of the existing building 2 which is a heat insulation repair site with the face material constituting the indoor space. A trunk edge 6 made of a foam insulation material having a width of about 15 mm and a thickness that is the same as the core material part 15 of the vacuum heat insulating material 4 or slightly thicker than the core material part 15 is arranged in the left-right direction. And is fixed by a tucker 5 that penetrates the inner wall 2 and penetrates the inner wall 2.

また、室内空間を構成する面材で断熱改修部位となる既存の建物の内壁２の室内側の面の左右の縁に、上下の縁に固定した胴縁６の間隔に合わせて縦方向（上下方向）に長く真空断熱材４の芯材部１５と同じ厚みか芯材部１５より若干厚い厚みで、幅が約１５ｍｍの発泡断熱材からなる胴縁６を配置して、胴縁６を貫通して内壁２に突き刺さるタッカー５で固定する。   Also, in the vertical direction (up and down) according to the interval of the trunk edge 6 fixed to the upper and lower edges, on the left and right edges of the indoor side surface of the inner wall 2 of the existing building 2 that becomes the heat insulation repair site with the face material constituting the indoor space The body edge 6 made of a foam heat insulating material having a width of about 15 mm and a thickness that is the same as or slightly thicker than the core material part 15 of the vacuum heat insulating material 4 is disposed in the direction) and penetrates the body edge 6. Then, it is fixed with a tucker 5 that pierces the inner wall 2.

また、室内空間を構成する面材で断熱改修部位となる既存の建物の内壁２の室内側の面の上下左右の縁に固定した胴縁６に囲まれた部分に、上下の縁に固定した胴縁６の間隔に合わせて縦方向（上下方向）に長く真空断熱材４の芯材部１５と同じ厚みか芯材部１５より若干厚い厚みで、幅が約１５ｍｍと約３０ｍｍの発泡断熱材からなる胴縁６を交互に配置して、胴縁６を貫通して内壁２に突き刺さるタッカー５で固定する。   Moreover, it fixed to the upper and lower edges at the part surrounded by the upper and lower right and left edges of the indoor side surface of the inner wall 2 of the existing building that becomes the heat insulation repair site with the face material constituting the indoor space. Foam heat insulating material which is long in the vertical direction (vertical direction) according to the interval between the trunk edges 6 and is the same thickness as the core material portion 15 of the vacuum heat insulating material 4 or slightly thicker than the core material portion 15 and has a width of about 15 mm and about 30 mm. The trunk edges 6 are alternately arranged and fixed by a tucker 5 penetrating the inner wall 2 through the trunk edges 6.

なお、幅が約３０ｍｍの胴縁６は左右に隣接する真空断熱材４の一方の左側の真空断熱材４の右側の外周熱溶着部１８と他方の右側の真空断熱材４の左側の外周熱溶着部１８を固定する部分にのみ用いる。   The body edge 6 having a width of about 30 mm is the outer peripheral heat welding portion 18 on the right side of the left vacuum insulating material 4 on the left side of the vacuum insulating material 4 adjacent to the left and right sides and the outer peripheral heat on the left side of the other right vacuum insulating material 4. Only used for fixing the welded portion 18.

壁面に垂直な方向が重力方向に対して略垂直になる内壁２に対しては、特にボード材８を胴縁６を介して内壁２に固定する場合は、縦方向（上下方向）に長い胴縁６の割合を横方向（左右方向）に長い胴縁６の割合より少なくするよりは、縦方向（上下方向）に長い胴縁６の割合を横方向（左右方向）に長い胴縁６の割合より多くする方が、安定する。   For the inner wall 2 in which the direction perpendicular to the wall surface is substantially perpendicular to the direction of gravity, especially when the board member 8 is fixed to the inner wall 2 via the trunk edge 6, the body is long in the vertical direction (vertical direction). The ratio of the long edge 6 in the vertical direction (vertical direction) is longer than the ratio of the long edge 6 in the horizontal direction (horizontal direction), rather than the ratio of the long edge 6 in the horizontal direction (left and right direction). Increasing the ratio is more stable.

胴縁６をタッカー５で固定する場合は、タッカー５が、胴縁６の幅方向の中央部分で、タッカー５の二つの先端部を結ぶ線が、胴縁６の長手方向に略平行になるように、また、タッカー５が内壁２に対して垂直になるように内壁２に打ち込む。   When the trunk edge 6 is fixed by the tucker 5, the line connecting the two tip portions of the tucker 5 is substantially parallel to the longitudinal direction of the trunk edge 6. In addition, the inner wall 2 is driven so that the tucker 5 is perpendicular to the inner wall 2.

このとき、左右方向に並ぶ複数の胴縁６の間隔は、真空断熱材４の一つの芯材部１５の左右の寸法より２〜１０ｍｍ程度広くなるものとする。   At this time, the interval between the plurality of trunk edges 6 arranged in the left-right direction is about 2 to 10 mm wider than the left and right dimensions of one core member 15 of the vacuum heat insulating material 4.

なお、タッカー５を打ち込む位置は、後にタッカー３を打ち込む位置と、後に釘７を打ち込む位置から所定間隔離れた位置にする。   In addition, the position where the tucker 5 is driven is set at a position spaced apart from the position where the tucker 3 is driven later and the position where the nail 7 is driven later.

次に、図４と図１０に示すように、既存の建物の内壁２の角部（例えば左下の角部）から、図３に示す真空断熱材４を、芯材部１５が横方向（左右方向）に並ぶような向きで、図１０に示すように芯材部１５の片面が内壁２の室内側の面に略接触し、さらに芯材間熱溶着部１７と外周熱溶着部１８が胴縁６の室内側の面に広く接触するように芯材間熱溶着部１７と外周熱溶着部１８を折り曲げて設置位置を決定し、芯材部１５の片面が内壁２の室内側の面に略接触した状態で動かないように手で真空断熱材４を押さえながら、芯材間熱溶着部１７の中心線上と外周熱溶着部１８における胴縁６の室内側の面に接触し芯材部１５から所定間隔離れた部分（外周熱溶着部１８における胴縁６に密着している部分の幅方向中央部分）をタッカー３で胴縁６に固定する。   Next, as shown in FIGS. 4 and 10, the vacuum insulating material 4 shown in FIG. 3 from the corner (for example, the lower left corner) of the inner wall 2 of the existing building, the core portion 15 extends in the lateral direction (left and right). 10), one side of the core member 15 is substantially in contact with the indoor side surface of the inner wall 2 as shown in FIG. 10, and the inter-core heat weld portion 17 and the outer peripheral heat weld portion 18 are in the body. The inter-core heat welding portion 17 and the outer peripheral heat welding portion 18 are bent so as to widely contact the indoor side surface of the edge 6 and the installation position is determined, and one side of the core material portion 15 is placed on the indoor side surface of the inner wall 2. While holding down the vacuum heat insulating material 4 by hand so as not to move in a substantially contacted state, the core material portion comes into contact with the inner side surface of the body edge 6 on the center line of the inter-core heat weld portion 17 and the outer peripheral heat weld portion 18. A portion (a central portion in the width direction of the portion of the outer peripheral heat-welded portion 18 that is in close contact with the trunk edge 6) that is a predetermined distance away from 15 is a tucker 3. It is fixed to the edge 6.

タッカー３は、タッカー３に近接する芯材部１５の縁（辺）とタッカー３の二つの先端部を結ぶ線が、略平行になるように打ち込む。   The tucker 3 is driven so that the line connecting the edge (side) of the core portion 15 adjacent to the tucker 3 and the two tip portions of the tucker 3 is substantially parallel.

このとき、既存の建物の内壁２の表面の突起物や内壁２の表面に付着した異物で、内壁２に略接触する芯材部１５の外被材１１が傷つかないように、予め、真空断熱材４を配設する面を平滑面にしておくことが望ましい。   At this time, vacuum insulation is performed in advance so that protrusions on the surface of the inner wall 2 of the existing building and foreign matter adhering to the surface of the inner wall 2 do not damage the outer covering material 11 of the core portion 15 that substantially contacts the inner wall 2. It is desirable that the surface on which the material 4 is disposed be a smooth surface.

その後、同様に、次の真空断熱材４を、図４と図５と図１１に示すように、先に固定した真空断熱材４と重ならず、また、先に固定した真空断熱材４とできるだけ間隔をあけないように、段方向（上方向）及び横方向にタッカー３にて固定する。本実施の形態では、図５に示すように、真空断熱材４を縦３段、横４列にわたってタッカー３で胴縁６に固定する。   Thereafter, similarly, the next vacuum heat insulating material 4 does not overlap with the previously fixed vacuum heat insulating material 4 as shown in FIGS. Fix with the tucker 3 in the step direction (upward direction) and in the lateral direction so as not to leave a gap as much as possible. In this Embodiment, as shown in FIG. 5, the vacuum heat insulating material 4 is fixed to the trunk edge 6 with the tucker 3 over 3 steps | paragraphs and 4 rows.

また、熱溶着部１６を貫通して胴縁６に突き刺さるタッカー３で、真空断熱材４を胴縁６に固定する場合は、タッカー３がタッカー５に接触しないように注意する。タッカー３がタッカー５に接触しないようにするには、タッカー５とタッカー３の位置を予め決めておいて、そのルール通りにタッカー５とタッカー３を打ち込むようにしたり、タッカー５を打ち込んだ後に、熱溶着部１６にタッカー５の位置が分かる印やタッカー３を打ち込むべき位置を示す印を付けて、その熱溶着部１６に付けた印をもとにタッカー３を打ち込んだりすれば良い。   In addition, when the vacuum heat insulating material 4 is fixed to the trunk edge 6 with the tucker 3 that penetrates the thermal welding portion 16 and pierces the trunk edge 6, care should be taken that the tucker 3 does not contact the tucker 5. To prevent the tucker 3 from coming into contact with the tucker 5, the positions of the tucker 5 and the tucker 3 are determined in advance, and the tucker 5 and the tucker 3 are driven according to the rules, or after the tucker 5 is driven, A mark indicating the position of the tucker 5 or a mark indicating the position where the tucker 3 should be driven may be attached to the heat welded portion 16, and the tucker 3 may be driven based on the mark attached to the heat welded portion 16.

本実施の形態では、各段の真空断熱材４については芯材間熱溶着部１７と左右の外周熱溶着部１８に２箇所ずつタッカー３を打ち込み、下段の真空断熱材４については下側の外周熱溶着部１８にも各芯材部１５の下側に２箇所ずつ合計４箇所タッカー３を打ち込み、上段の真空断熱材４については上側の外周熱溶着部１８にも各芯材部１５の上側に２箇所ずつ合計４箇所タッカー３を打ち込んでいる。   In this embodiment, the vacuum heat insulating material 4 at each stage is driven by two tuckers 3 into the inter-core heat welded portion 17 and the left and right outer peripheral heat welded portions 18, and the lower vacuum heat insulating material 4 is A total of four tuckers 3 are driven into the outer peripheral heat welded portion 18 at two locations below each core member 15, and the upper vacuum heat-insulating member 4 also has an upper outer peripheral heat welded portion 18 formed of each core member 15. A total of four tuckers 3 are driven in two places on the upper side.

また、内壁２の室内側の面の上下の縁に固定された胴縁６のタッカー５の位置は、各芯材部１５を左右に二等分する線上と交差する位置にしており、各芯材部１５の上または下側に２箇所ずつ打ち込むタッカー３の位置は、内壁２の室内側の面の上下の縁に固定された胴縁６のタッカー５の位置から左右方向にずらしている。   Further, the position of the tucker 5 of the trunk edge 6 fixed to the upper and lower edges of the indoor side surface of the inner wall 2 is set to a position intersecting with a line that bisects each core member portion 15 to the left and right. The position of the tucker 3 that is driven in two places above or below the material portion 15 is shifted in the left-right direction from the position of the tucker 5 of the trunk edge 6 fixed to the upper and lower edges of the indoor side surface of the inner wall 2.

また、内壁２の室内側の面の上下の縁に固定された胴縁６の間に配置される縦方向（上下方向）に長い胴縁６を固定するタッカー５の位置は、各芯材部１５の角部の左側または右側で各芯材部１５の上下方向中央寄りにしており、芯材間熱溶着部１７と左右の外周熱溶着部１８に２箇所ずつ打ち込むタッカー３の位置は、縦方向（上下方向）に長い胴縁６のタッカー５の位置よりも各芯材部１５の上下方向中央寄りにずらしている。   Moreover, the position of the tucker 5 which fixes the long trunk edge 6 arrange | positioned between the trunk edges 6 fixed to the upper and lower edges of the indoor side surface of the inner wall 2 is each core part. The position of the tucker 3 that is driven near the center in the vertical direction of each core member 15 on the left or right side of the corner portion 15 and is driven into the inter-core heat welded portion 17 and the left and right outer peripheral heat welded portions 18 in two places The core members 15 are shifted toward the center in the vertical direction from the position of the tucker 5 of the trunk edge 6 that is long in the direction (vertical direction).

また、胴縁６における真空断熱材４と接触する面は、胴縁６の表面の突起物や胴縁６の表面に付着した異物で、真空断熱材４が傷つかないように、予め、真空断熱材４と接触する面平滑面にしておくことが望ましい。   In addition, the surface in contact with the vacuum heat insulating material 4 at the trunk edge 6 is preliminarily vacuum insulated so that the vacuum heat insulating material 4 is not damaged by protrusions on the surface of the trunk edge 6 or foreign matter adhering to the surface of the trunk edge 6. It is desirable to have a smooth surface in contact with the material 4.

次に、図６と図７と図１２に示すように、真空断熱材４を室内側から覆い隠すように、所定寸法の大きさ（本実施の形態では、断熱改修部位となる既存の建物の内壁２を左右に二等分した（断熱壁１を左右に二等分した）大きさ）に切断された石膏ボードからなるボード材８を、２枚、ボード材８と胴縁６を貫通して内壁２に突き刺さる釘７固定する。   Next, as shown in FIGS. 6, 7, and 12, the size of a predetermined dimension (in the present embodiment, the existing building to be a heat insulation refurbishment site) so as to cover the vacuum heat insulating material 4 from the indoor side. Two pieces of board material 8 made of gypsum board that has been cut into two halves of the inner wall 2 (the size of the heat insulation wall 1 is divided into left and right parts) penetrate the board material 8 and the trunk edge 6. The nail 7 that pierces the inner wall 2 is fixed.

なお、ボード材８において釘７を打ち込む位置は、釘７が胴縁６の幅方向の略中央を貫通可能な位置に限定しており、具体的には、ボード材８の四隅と、ボード材８の上下の縁を左右方向に４等分する位置と、内壁２の室内側の面の上下の縁に固定された胴縁６の間に配置される縦方向（上下方向）に長い胴縁６とボード材８を上下方向に３等分する線とが交差する位置であり、この条件を満足する位置を避けてタッカー３とタッカー５を打ち込んでいるので、打ち込んだ釘７がタッカー３またはタッカー５に衝突することはない。   In addition, the position where the nail 7 is driven in the board material 8 is limited to a position where the nail 7 can penetrate substantially the center of the trunk edge 6 in the width direction. Specifically, the four corners of the board material 8 and the board material A vertical trunk (vertical direction) that is long between a position that divides the upper and lower edges of 8 into four equal parts in the left-right direction and a trunk edge 6 that is fixed to the upper and lower edges of the inner surface of the inner wall 2. 6 and the line that divides the board material 8 into three equal parts in the vertical direction. The tucker 3 and the tucker 5 are driven away from the position satisfying this condition. There is no collision with Tucker 5.

真空断熱材４の芯材部１５がボード材８と接触する場合は、ボード材８における真空断熱材４側の表面の突起物や表面に付着した異物で、芯材部１５の外被材１１が傷つかないように、予め、ボード材８における真空断熱材４側の表面を平滑面にしておくことが望ましい。   When the core material portion 15 of the vacuum heat insulating material 4 is in contact with the board material 8, the outer cover material 11 of the core material portion 15 is formed by protrusions on the surface of the board heat material 8 on the vacuum heat insulating material 4 side or foreign matter adhering to the surface. It is desirable that the surface of the board material 8 on the side of the vacuum heat insulating material 4 is made smooth in advance so as not to be damaged.

次に、図８と図１３に示すように、ボード材８の室内側の面を壁紙９で覆って釘７やボード材８の継ぎ目が見えないようにする。   Next, as shown in FIGS. 8 and 13, the inner surface of the board material 8 is covered with wallpaper 9 so that the joints of the nails 7 and the board material 8 are not visible.

本実施の形態では、胴縁６をタッカー５で内壁２に固定しているが、釘やネジを代わりに用いても構わない。また、ボード材８を釘７で胴縁６と内壁２に固定しているが、タッカーやネジを代わりに用いても構わない。   In the present embodiment, the trunk edge 6 is fixed to the inner wall 2 by the tucker 5, but nails or screws may be used instead. Moreover, although the board | plate material 8 is being fixed to the trunk edge 6 and the inner wall 2 with the nail 7, a tucker and a screw may be used instead.

本実施の形態の断熱壁１は、室内空間を構成する面材（内壁２）と、面材（内壁２）の室内側の面に固定された複数の胴縁６と、芯材１２を外被材１１で減圧密封して成り外被材１１の間に芯材１２がある芯材部１５が互いに隣接する胴縁６と胴縁６との間で面材（内壁２）の室内側の面に略接触するように配置された真空断熱材４と、真空断熱材４を室内側から覆い隠すように胴縁６に固定されたボード材８とからなり、胴縁６が芯材部１５の厚み以上の厚みを有し、真空断熱材４における外被材１１の間に芯材１２が無く対向する外被材１１同士が熱溶着された熱溶着部１６の一部のみが胴縁６とボード材８との間に位置するものである。   The heat insulating wall 1 according to the present embodiment includes a face member (inner wall 2) constituting an indoor space, a plurality of trunk edges 6 fixed to the indoor side surface of the face member (inner wall 2), and a core member 12 outside. The core material portion 15 having the core material 12 between the outer material 11 and the outer material 11 is sealed under reduced pressure with the material 11 between the inner edge 6 and the inner edge 6 of the face material (inner wall 2). The vacuum heat insulating material 4 arranged so as to be substantially in contact with the surface, and the board material 8 fixed to the trunk edge 6 so as to cover the vacuum heat insulating material 4 from the indoor side. Only a part of the heat-welded portion 16 having the core material 12 between the outer cover materials 11 in the vacuum heat insulating material 4 without the core material 12 and being welded to each other is only the trunk edge 6. And the board material 8.

これにより、室内空間を構成する面材（内壁２）の室内側の面の所定位置に複数の胴縁６を固定し、次に、真空断熱材４の芯材部１５が互いに隣接する胴縁６と胴縁６との間で面材（内壁２）の室内側の面に略接触するように、且つ、熱溶着部１６の一部のみが胴縁６の室内側の面の少なくとも一部を覆うように、真空断熱材４を配置（固定）し、次に、ボード材８を、真空断熱材４を室内側から覆い隠すように胴縁６に固定することにより、現場発泡の発泡断熱材を用いることなく、容易に施工可能で断熱性能が良好な断熱壁１を得ることができ、既存壁（内壁２）を断熱壁１にする場合は、既存壁（内壁２）を解体する必要はなく、壁紙の張り替えに近いレベルで簡単に断熱強化を行うことができるため、工事期間・工事費用においても非常に有利となる効果が得られる。   As a result, the plurality of trunk edges 6 are fixed at predetermined positions on the indoor side surface of the face material (inner wall 2) constituting the indoor space, and then the core edges 15 of the vacuum heat insulating material 4 are adjacent to each other. 6 and the barrel edge 6 so that they substantially come into contact with the indoor side surface of the face material (inner wall 2), and only a part of the heat welding portion 16 is at least a part of the indoor side surface of the trunk edge 6 The vacuum heat insulating material 4 is disposed (fixed) so as to cover the board, and then the board material 8 is fixed to the trunk edge 6 so as to cover the vacuum heat insulating material 4 from the indoor side. Without using materials, it is possible to obtain a heat insulating wall 1 that can be easily constructed and has good heat insulating performance. When the existing wall (inner wall 2) is used as the heat insulating wall 1, it is necessary to disassemble the existing wall (inner wall 2). However, it is possible to easily insulate at a level close to wallpaper replacement, so even in the construction period and cost Always advantageous to become effect can be obtained.

また、真空断熱材４はスチレンフォーム等の汎用の断熱材に比べて断熱性能が非常に優れているため、断熱材部分の厚みを薄くでき、その結果、断熱壁１を薄くできる。また、真空断熱材４を設ける面材を既存壁（内壁２）にする場合は、断熱壁１とすることによる室内側への壁面の出っ張り寸法を小さくできるので、問題なく適用可能な範囲が広く実用的である。   Moreover, since the heat insulating performance of the vacuum heat insulating material 4 is very superior to general-purpose heat insulating materials such as styrene foam, the thickness of the heat insulating material portion can be reduced, and as a result, the heat insulating wall 1 can be reduced. Further, in the case where the face material provided with the vacuum heat insulating material 4 is an existing wall (inner wall 2), since the protruding dimension of the wall surface to the indoor side by using the heat insulating wall 1 can be reduced, the applicable range without problems is wide. It is practical.

また、ボード材８を胴縁６に固定した後は、真空断熱材４の熱溶着部１６の一部を、胴縁６とボード材８とで挟んで固定できるので、ボード材８を胴縁６に固定する前の真空断熱材４の固定を、ボード材８を胴縁６に固定するまでの仮固定にすることができ、ボード材８を胴縁６に固定する前の真空断熱材４の胴縁６または面材（内壁２）への固定に、時間の経過により固定または接着の機能が低下するような固定手段を用いることができ、固定手段の選択肢が多く、固定手段の選択によっては、作業性の向上やコスト低減が可能になる。   In addition, after the board material 8 is fixed to the trunk edge 6, a part of the heat welding portion 16 of the vacuum heat insulating material 4 can be sandwiched and fixed between the trunk edge 6 and the board material 8. The fixing of the vacuum heat insulating material 4 before being fixed to 6 can be temporarily fixed until the board material 8 is fixed to the trunk edge 6, and the vacuum insulating material 4 before the board material 8 is fixed to the trunk edge 6. Can be used for fixing to the body edge 6 or the face material (inner wall 2), and there are many fixing means that can be used for fixing or bonding functions to be reduced over time. Can improve workability and reduce costs.

また、胴縁６が芯材部１５の厚み以上の厚みを有するので、ボード材８が真空断熱材４の芯材部１５により圧迫されることがない。これにより、ボード材８を平面状態に施工することができる。また、ボード材８による負荷が芯材部１５にかかりにくいため、外被材１１が損傷し難くなり真空断熱材４の内圧上昇を低減することが可能となるため、長期間にわたって高断熱性能な断熱壁１を維持することができる。   Moreover, since the trunk edge 6 has a thickness equal to or greater than the thickness of the core material portion 15, the board material 8 is not pressed by the core material portion 15 of the vacuum heat insulating material 4. Thereby, the board | plate material 8 can be constructed in a planar state. In addition, since the load due to the board material 8 is not easily applied to the core material portion 15, it is difficult to damage the jacket material 11 and the increase in the internal pressure of the vacuum heat insulating material 4 can be reduced. The heat insulating wall 1 can be maintained.

また、胴縁６と芯材部１５の厚みの差を、真空断熱材４（芯材部１５）の内圧が大気圧近くまで上昇して、芯材部１５が膨む場合の芯材部１５の厚みの増加分以上にすれば、真空断熱材４（芯材部１５）の内圧が大気圧近くまで上昇して、芯材部１５が膨れ厚くなった時に、ボード材８と芯材部１５との隙間で、芯材部１５の厚みの増加分を吸収でき、ボード材８が芯材部１５により押されて室内側に膨らむ問題をなくすことが可能となる。   Further, the difference in thickness between the trunk edge 6 and the core member 15 causes the core member 15 to be expanded when the internal pressure of the vacuum heat insulating material 4 (core member 15) rises to near atmospheric pressure and the core member 15 expands. When the internal pressure of the vacuum heat insulating material 4 (core material portion 15) rises to near atmospheric pressure and the core material portion 15 swells and becomes thicker, the board material 8 and the core material portion 15 are increased. Thus, the increase in the thickness of the core member 15 can be absorbed, and the problem that the board member 8 is pushed by the core member 15 and swells indoors can be eliminated.

なお、面材（内壁２）と芯材部１５との隙間、またはボード材８と芯材部１５との隙間は、１５ｍｍ以下であることが好ましく、上記隙間が１５ｍｍ以下であれば、隙間の空気の対流を抑えることができ、隙間の空気の対流による断熱壁１の断熱性の悪化を抑えることができる。   The gap between the face material (inner wall 2) and the core member 15 or the gap between the board member 8 and the core member 15 is preferably 15 mm or less, and if the gap is 15 mm or less, the gap Air convection can be suppressed, and deterioration of the heat insulating property of the heat insulating wall 1 due to air convection in the gap can be suppressed.

また、芯材部１５が面材（内壁２）とボード材８と胴縁６とによって形成される空間に位置し、熱溶着部１６の一部が胴縁６の室内側の面の少なくとも一部を覆うように、真空断熱材４を配置したので、胴縁６がない部分における芯材部１５（真空断熱材４の有効断熱部）が覆う面積の割合を大きくでき、高断熱性能の断熱壁１を提供できる。   Further, the core member 15 is located in a space formed by the face member (inner wall 2), the board member 8, and the trunk edge 6, and a part of the heat-welded portion 16 is at least one of the indoor side surfaces of the trunk edge 6. Since the vacuum heat insulating material 4 is arranged so as to cover the portion, the ratio of the area covered by the core material portion 15 (the effective heat insulating portion of the vacuum heat insulating material 4) in the portion where there is no trunk edge 6 can be increased, and heat insulation with high heat insulating performance Wall 1 can be provided.

また、芯材部１５の厚み以上の厚みの複数の胴縁６を面材（内壁２）の室内側の面に固定した後に、真空断熱材４を配置するので、特に断熱壁１を住宅（建物）の床に適用する場合は、断熱壁１の施工時に、施工作業者が、胴縁６を活用して芯材部１５に大きな負荷（体重など）をかけることなく、断熱壁１を施工できる。   Moreover, since the vacuum heat insulating material 4 is arrange | positioned after fixing the several trunk edge 6 of the thickness more than the thickness of the core material part 15 to the indoor surface of a face material (inner wall 2), especially the heat insulating wall 1 is a house ( When applying to the floor of a building), the construction worker constructs the heat insulation wall 1 without applying a heavy load (weight, etc.) to the core portion 15 by using the trunk edge 6 when constructing the heat insulation wall 1. it can.

また、本実施の形態では、真空断熱材４として、熱溶着層１０同士が対向するガスバリア性でフレキシブルな外被材１１の間に、板状の芯材１２が配置されて、外被材１１の間に芯材１２が無い部分の外被材１１同士を密着させて、密着した外被材１１同士を熱溶着してなり、外被材１１同士が密着する全ての部分の外被材１１同士が熱溶着されている真空断熱材４を用いた。   Moreover, in this Embodiment, the plate-shaped core material 12 is arrange | positioned as the vacuum heat insulating material 4 between the gas barrier property flexible outer covering materials 11 in which the heat-welding layers 10 face each other, and the outer covering material 11 is arranged. A portion of the outer cover material 11 in which the core material 12 is not in contact with each other, and the outer cover materials 11 that are in close contact with each other are thermally welded. The vacuum heat insulating material 4 by which the two were heat-welded was used.

これにより、真空断熱材４は、外被材１１同士が密着する部分は外被材１１の間に芯材１２がある部分の近傍まで熱溶着されているので、外周部分の外被材１１同士のみ熱溶着された真空断熱材に比べて熱溶着部１６の幅が広く、それにより胴縁６と熱溶着部１６との接触面積を広くできるため、胴縁６と熱溶着部１６との接触面積を広くして胴縁６とボード材８とによって真空断熱材４をより確実に固定できる。   As a result, in the vacuum heat insulating material 4, the portion where the covering materials 11 are in close contact with each other is thermally welded to the vicinity of the portion where the core material 12 is between the covering materials 11. Compared to the vacuum heat-insulating material that has been heat-welded only, the width of the heat-welded portion 16 is wider, so that the contact area between the body edge 6 and the heat-welded portion 16 can be increased. The vacuum heat insulating material 4 can be more securely fixed by the body edge 6 and the board material 8 with a wide area.

また、熱溶着部１６が胴縁６（とボード材８）から受ける押圧力を広い接触面積で受けると、胴縁６（とボード材８）と熱溶着部１６との接触部分における単位面積あたりの押圧力が小さくなるため、胴縁６（とボード材８）と熱溶着部１６との接触面積を広くして胴縁６（とボード材８）による真空断熱材４の熱溶着部１６の損傷の可能性を小さくすることができ、外被材１１同士が密着する部分は外被材１１の間に芯材１２がある部分の近傍まで熱溶着されているので、胴縁６（とボード材８）と熱溶着部１６との接触で熱溶着部１６が損傷したり、真空断熱材４を芯材部１５から所定間隔以上離れた熱溶着部１６を貫通して胴縁６に突き刺さる部材（タッカー３）で固定したり、ボード材８をボード材８と芯材部１５から所定間隔以上離れた熱溶着部１６と胴縁６を貫通して面材（内壁２）に突き刺さる部材（釘７）で固定した場合でも、熱溶着部１６の損傷部分や貫通孔ができた部分の芯材１２側に充分な幅の熱溶着部１６が残るので、真空断熱材４の断熱性能悪化の可能性が少なく、断熱性能の信頼性が高い断熱壁１になる。   Further, when the pressing force received by the thermal welding portion 16 from the trunk edge 6 (and the board material 8) is received in a wide contact area, the unit area at the contact portion between the trunk edge 6 (and the board material 8) and the thermal welding portion 16 Therefore, the contact area between the body edge 6 (and the board material 8) and the heat welding part 16 is widened, and the heat welding part 16 of the vacuum heat insulating material 4 by the body edge 6 (and the board material 8) is increased. Since the possibility of damage can be reduced, and the portion where the jacket materials 11 are in close contact with each other is thermally welded to the vicinity of the portion where the core material 12 is between the jacket materials 11, the trunk edge 6 (and the board) The member which damages the heat welding part 16 by contact with the material 8) and the heat welding part 16, or penetrates the vacuum heat insulating material 4 through the heat welding part 16 which is separated from the core material part 15 by a predetermined distance or more to the trunk edge 6 (Tucker 3) or the board material 8 is more than a predetermined distance from the board material 8 and the core material part 15 Even when the heat welded part 16 and the body edge 6 are passed through and fixed with a member (nail 7) that penetrates the face material (inner wall 2), the core material of the part where the heat welded part 16 is damaged or has a through hole Since the heat-welded portion 16 having a sufficient width remains on the side 12, the heat insulating wall 1 is less likely to deteriorate the heat insulating performance of the vacuum heat insulating material 4 and has high reliability of the heat insulating performance.

また、外被材１１同士が密着する部分は外被材１１の間に芯材１２がある部分の近傍まで熱溶着されているので、壁の厚みに垂直な方向で外被材１１の間に芯材１２がある部分と胴縁６との間隔を狭くしても、外被材１１の損傷で真空断熱材４の断熱性能が悪化する可能性が少なく、そのため、芯材部１５と胴縁６との間隔を狭くして断熱壁１における真空断熱材４の有効断熱部である芯材部１５の被覆率を高めて断熱壁１の全体の断熱性能を高めることができる。   Further, since the portion where the covering materials 11 are in close contact with each other is thermally welded between the covering materials 11 to the vicinity of the portion where the core material 12 is present, the covering material 11 is interposed between the covering materials 11 in the direction perpendicular to the wall thickness. Even if the space between the core material 12 and the trunk edge 6 is narrowed, there is little possibility that the heat insulation performance of the vacuum heat insulating material 4 will be deteriorated due to damage of the jacket material 11, and therefore the core material portion 15 and the trunk edge The space | interval with 6 can be narrowed, the coverage of the core part 15 which is an effective heat insulation part of the vacuum heat insulating material 4 in the heat insulation wall 1 can be raised, and the heat insulation performance of the whole heat insulation wall 1 can be improved.

また、本実施の形態では、真空断熱材４として、複数の芯材１２が、厚み方向に略垂直な方向に互いに所定間隔離して配置されて、複数の芯材１２のそれぞれが独立した空間内に位置するように、隣接する芯材１２と芯材１２との間に外被材１１同士が熱溶着された熱溶着部１６（芯材間熱溶着部１７）を設けている真空断熱材４を用いた。   In the present embodiment, as the vacuum heat insulating material 4, a plurality of core members 12 are arranged separated from each other by a predetermined distance in a direction substantially perpendicular to the thickness direction, and each of the plurality of core members 12 is in an independent space. The vacuum heat insulating material 4 is provided with a heat welding portion 16 (inter-core heat welding portion 17) in which the jacket materials 11 are heat-welded between the adjacent core materials 12 so as to be positioned at each other. Was used.

これにより、外被材１１にピンホールができたり外被材１１が破損（破袋）したりして芯材１２を減圧密封した空間（芯材部１５）の内圧が上昇して断熱性能が悪化する場合でも、ピンホールや破損（破袋）の影響を直接受ける特定の芯材１２を減圧密封した空間（芯材部１５）内の圧力が高くなって断熱性能が悪化するだけで、断熱性能の悪化が真空断熱材４全体に広がらず、真空断熱材４としての断熱性の悪化は小さくできる効果が得られる。また、一つの真空断熱材４を配置（固定）する作業で、複数の芯材部１５を配置（固定）できる。   As a result, a pinhole is formed in the jacket material 11 or the jacket material 11 is broken (bag breakage), and the internal pressure of the space (core material portion 15) in which the core material 12 is sealed under reduced pressure is increased, so that the heat insulation performance is improved. Even if it deteriorates, the pressure in the space (core material portion 15) in which the specific core material 12 that is directly affected by pinholes or breakage (bag breakage) is sealed under reduced pressure becomes high and the heat insulation performance deteriorates. The deterioration of the performance does not spread over the entire vacuum heat insulating material 4, and the effect of reducing the deterioration of the heat insulating property as the vacuum heat insulating material 4 is obtained. Moreover, the several core material part 15 can be arrange | positioned (fixed) by the operation | work which arrange | positions (fixes) one vacuum heat insulating material 4. FIG.

また、本実施の形態では、真空断熱材４における互いに隣接する芯材部１５と芯材部１５との間の外被材１１同士が熱溶着された熱溶着部１６（芯材間熱溶着部１７）の一部が胴縁６とボード材８との間に位置しているので、互いに隣接する芯材部１５と芯材部１５との間の外被材１１同士が溶着された熱溶着部１６（芯材間熱溶着部１７）を有効に活用でき、互いに隣接する芯材部１５と芯材部１５との間の外被材１１同士が溶着された熱溶着部１６（芯材間熱溶着部１７）が胴縁６とボード材８との間に位置していない場合に比べて、胴縁６がない部分における芯材部１５（真空断熱材４の有効断熱部）が覆う面積の割合を大きくでき、高断熱性能の断熱壁１を提供できる。   Moreover, in this Embodiment, the heat welding part 16 (heat-welding part between core materials) to which the jacket material 11 between the core material parts 15 and the core material part 15 which adjoin each other in the vacuum heat insulating material 4 was heat-welded. 17) is partly located between the trunk edge 6 and the board material 8, so that the outer cover material 11 between the core material part 15 and the core material part 15 adjacent to each other is welded. Part 16 (inter-core heat welding part 17) can be used effectively, and the heat-welded part 16 (between core materials) in which the jacket materials 11 between the core part 15 and the core part 15 adjacent to each other are welded Compared to the case where the heat-welded portion 17) is not located between the body edge 6 and the board material 8, the area covered by the core material portion 15 (the effective heat insulating portion of the vacuum heat insulating material 4) in the portion where the body edge 6 is not present. Therefore, the heat insulating wall 1 having high heat insulating performance can be provided.

また、本実施の形態では、真空断熱材４が、芯材部１５から所定間隔以上離れた熱溶着部１６を貫通して胴縁６に突き刺さる部材（タッカー３）で固定されているが、本実施の形態で用いる真空断熱材４は、外被材１１同士が密着する全ての部分の外被材１１同士が熱溶着されている真空断熱材４であり、外被材１１同士が密着する部分は外被材１１の間に芯材１２がある部分の近傍まで熱溶着されているので、外周部分の外被材１１同士のみ熱溶着された真空断熱材に比べて熱溶着部１６の幅が広く、熱溶着部１６を貫通して胴縁６に突き刺さることにより真空断熱材４を胴縁６に固定する部材（釘、ネジ、タッカー（ステープラー）等）は、芯材部１６から所定間隔以上離れた熱溶着部１６を貫通するので、真空断熱材４の断熱性能を低下させることなく、真空断熱材４を胴縁６に固定する部材によってできる貫通孔で真空断熱材４の断熱性能を低下させることがほとんどなく、釘、ネジ、タッカー（ステープラー）等の部材で、容易に真空断熱材４を胴縁６に固定できる。   Moreover, in this Embodiment, although the vacuum heat insulating material 4 is fixed with the member (Tucker 3) which penetrates the thermal welding part 16 spaced apart from the core part 15 more than predetermined interval, and pierces the trunk edge 6, The vacuum heat insulating material 4 used in the embodiment is a vacuum heat insulating material 4 in which all the outer covering materials 11 in which the outer covering materials 11 are in close contact with each other are thermally welded, and a portion in which the outer covering materials 11 are in close contact with each other. Is thermally welded to the vicinity of the portion where the core material 12 is between the jacket materials 11, so that the width of the heat welded portion 16 is larger than that of the vacuum heat insulating material in which only the jacket materials 11 of the outer peripheral portion are thermally welded. A member (a nail, a screw, a tucker (stapler), etc.) for fixing the vacuum heat insulating material 4 to the body edge 6 by penetrating the heat welding part 16 and sticking to the body edge 6 is more than a predetermined distance from the core material part 16. Since it penetrates the remote heat welding part 16, the heat insulation performance of the vacuum heat insulating material 4 is low. The through-hole made by the member that fixes the vacuum heat insulating material 4 to the body edge 6 is hardly deteriorated, and the heat insulating performance of the vacuum heat insulating material 4 is hardly deteriorated, and it is easy to use a member such as a nail, a screw, a tucker (stapler), etc. The vacuum heat insulating material 4 can be fixed to the trunk edge 6.

また、本実施の形態では、ボード材８が、ボード材８と胴縁６を貫通して面材（内壁２）に突き刺さる部材（釘７）で固定されたものであり、ボード材８がボード材８を貫通して胴縁６に突き刺さる（胴縁６を貫通しない）部材で固定される場合よりも、しっかりとボード材８を固定できる。   In the present embodiment, the board material 8 is fixed by a member (nail 7) that penetrates the board material 8 and the trunk edge 6 and pierces the face material (inner wall 2). The board material 8 can be fixed more firmly than the case where it is fixed by a member that penetrates the material 8 and pierces the trunk edge 6 (does not penetrate the trunk edge 6).

また、本実施の形態では、胴縁６が、断熱性のある材料で構成したことにより、胴縁６を経由して面材（内壁２）とボード材８との間で伝わる熱の量を、胴縁６の断熱性により低減することができる。   Moreover, in this Embodiment, since the trunk | drum 6 comprised the material with heat insulation, the quantity of the heat | fever transmitted between a face material (inner wall 2) and the board | substrate material 8 via the trunk | drum 6 was reduced. It can be reduced by the heat insulating property of the trunk edge 6.

また、本実施の形態では、ボード材８に石膏ボードを使用していることにより、安価で優れた耐火性を有することができる効果（断熱改修費用を安くできると共に、火事発生の場合における延焼を防ぐことができる効果）が得られる。また、断熱壁１に、人・物等が接触した場合においても、石膏ボードは十分な厚みと剛性を有するため、その衝撃等により石膏ボードの内部に配置されている真空断熱材４の破袋を防止することができる効果が得られる。   In the present embodiment, the use of gypsum board for the board material 8 has the effect of being inexpensive and having excellent fire resistance (heat insulation repair cost can be reduced and spreading fire in the event of a fire occurrence). Effects that can be prevented). Further, even when a person or an object comes into contact with the heat insulating wall 1, the gypsum board has sufficient thickness and rigidity, so that the bag breakage of the vacuum heat insulating material 4 disposed inside the gypsum board due to the impact or the like.
