以下、本発明の実施の形態について、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１は、本発明の実施の形態１における断熱パネルの正面図である。図２は、本発明の実施の形態１における断熱パネルの側面図である。図３は、本発明の実施の形態１における真空断熱材１の断面図である。 (Embodiment 1)
FIG. 1 is a front view of a heat insulating panel according to Embodiment 1 of the present invention. FIG. 2 is a side view of the heat insulation panel according to Embodiment 1 of the present invention. FIG. 3 is a cross-sectional view of the vacuum heat insulating material 1 according to Embodiment 1 of the present invention.

図１、図２、図３において、断熱パネル６は、真空断熱材１を備え、真空断熱材１はラミネートフィルム２の内部に複数個に分割した芯材５と、芯材３を備え、真空引きして、それぞれ個別に密封したものである。   1, 2, and 3, a heat insulating panel 6 includes a vacuum heat insulating material 1, and the vacuum heat insulating material 1 includes a core material 5 divided into a plurality of laminate films 2 and a core material 3, and a vacuum. Pulled and individually sealed.

複数個に分割した芯材５は、住宅等に接合するときの接合部７に配置される。真空断熱材１は接着剤等によりパネル４と接合し、断熱パネル６ができる。真空断熱材１は、面状のヒーターでラミネートフィルム２を溶着することにより、多数の形状の違った芯材を同時に真空密封することができる。   The core material 5 divided into a plurality of parts is arranged at the joint 7 when joining to a house or the like. The vacuum heat insulating material 1 is joined to the panel 4 with an adhesive or the like to form a heat insulating panel 6. The vacuum heat insulating material 1 can vacuum-seal a large number of different core materials simultaneously by welding the laminate film 2 with a planar heater.

以上のように構成された断熱パネルについて、以下その作用を説明する。   The effect | action is demonstrated below about the heat insulation panel comprised as mentioned above.

断熱パネル６を住宅等の建材や壁材として、複数個に分割した芯材５が配置された接合部７において釘やネジによって壁材として住宅に接合される。また、パネル４と真空断熱材１を接合する前に住宅の壁材として組み込み、一括して釘、ネジ等により接合してもよい。また、断熱パネル６として住宅に入れるのではなく、既存の住宅の壁材に真空断熱材１のみを接合して使用することもできる。   The heat insulating panel 6 is joined to the house as a wall material by a nail or a screw at the joint portion 7 where the core material 5 divided into a plurality of parts is arranged as a building material or a wall material such as a house. Moreover, before joining the panel 4 and the vacuum heat insulating material 1, you may incorporate as a wall material of a house, and may join together with a nail, a screw, etc. collectively. Moreover, instead of putting it in the house as the heat insulating panel 6, it is possible to use only the vacuum heat insulating material 1 joined to the wall material of the existing house.

以上のように、本実施の形態において、真空断熱材１はラミネートフィルム２の内部に複数個に分割した芯材５と、その他の部分に芯材３を備え、面状のヒーター等によりそれぞれ個別に真空密封されたものであり、住宅等と接合される接合部７に複数個に分割した芯材５が配置されているので、釘等の接合により数個の真空が常圧に戻ってしまっても他の真空がリークすることがないので断熱性能に大きな影響がなく、またその他の部分の芯材は複数個に分割した芯材５ほど分割されていないので、芯材被覆率の低下による断熱性能の低下を抑えることができる。   As described above, in the present embodiment, the vacuum heat insulating material 1 includes the core material 5 divided into a plurality of parts inside the laminate film 2 and the core material 3 in other portions, and is individually provided by a planar heater or the like. Since the core material 5 divided into a plurality of parts is arranged in the joint 7 to be joined to a house or the like, several vacuums have returned to normal pressure by joining nails or the like. However, since no other vacuum leaks, the heat insulation performance is not greatly affected, and the core material in other parts is not divided as much as the core material 5 divided into a plurality of parts, so that the core material coverage rate is reduced. A decrease in heat insulation performance can be suppressed.

また、断熱パネル６を釘等により安価な方法で容易に壁材に適用することが可能となる。なお、複数個に分割した芯材５の大きさを小さくすると、ヒートリークが大きくなり断熱性能が低下するが、ラミネートフィルムの金属層を蒸着層にすることで、ガスバリア性の低下を抑えつつ、ヒートリークを小さくできるので、断熱性能の低下を抑えることができる。   Moreover, it becomes possible to apply the heat insulation panel 6 to a wall material easily by an inexpensive method using a nail or the like. In addition, if the size of the core material 5 divided into a plurality is reduced, the heat leak increases and the heat insulation performance decreases, but by making the metal layer of the laminate film a vapor deposition layer, while suppressing the decrease in gas barrier properties, Since heat leak can be reduced, it is possible to suppress a decrease in heat insulation performance.

また、複数個に分割された芯材５が配置された個所の上に位置するパネル４の外観の色を変える、模様を変える等することにより、釘打ちできる個所が明確にわかり、誤った個所に釘打ちするのを抑えることができる。   Also, by changing the color of the appearance of the panel 4 located on the place where the core material 5 divided into a plurality of parts is arranged, changing the pattern, etc., the place where nailing can be clearly understood and the wrong place It is possible to suppress nailing.

また、図１のように２辺にのみ複数個に分割した芯材５を配置すると、釘等で打てる個所が容易にわかり、接合し易くなる。また、真空断熱材の2辺だけにあるので芯材被覆率が高く、断熱性能が高い。また、対面する２辺で接合することができるので、しっかり接合でき、剥れ難い。   Further, when the core material 5 divided into a plurality of parts on only the two sides as shown in FIG. 1 is arranged, a place where it can be struck with a nail or the like can be easily understood and joined easily. Moreover, since it is only on the two sides of the vacuum heat insulating material, the core material coverage is high and the heat insulating performance is high. Moreover, since it can join in two sides which face, it can join firmly and does not peel easily.

Arranged, the core material 3 is arranged in other parts, vacuumed, and individually sealed. The vacuum heat insulating material 1 is joined to the panel 4 with an adhesive or the like.

真空断熱材１は、面状のヒーターでラミネートフィルム２を溶着することにより、多数の形状の違った芯材を同時に真空密封することができる。ここで、接着剤により真空断熱材１とパネル４を接合するとしたが、複数個に分割された芯材５が配置された個所において釘、ネジ等で接合してもよい。   The vacuum heat insulating material 1 can vacuum-seal a large number of different core materials simultaneously by welding the laminate film 2 with a planar heater. Here, the vacuum heat insulating material 1 and the panel 4 are joined by an adhesive, but may be joined by a nail, a screw, or the like at a place where the core material 5 divided into a plurality of parts is disposed.

以上のように構成された断熱パネルについて、以下その作用を説明する。   The effect | action is demonstrated below about the heat insulation panel comprised as mentioned above.

断熱パネル６を住宅等の建材や壁材として、複数個に分割した芯材５を配置した周辺部において釘やネジによって壁材として住宅に接合される。また、パネル４と真空断熱材１を接合する前に住宅の壁材として組み込み、一括して釘、ネジ等により接合してもよい。また、断熱パネル６として住宅に入れるのではなく、既存の住宅の壁材に真空断熱材１のみを接合して使用することもできる。   The heat insulating panel 6 is joined to the house as a wall material by a nail or a screw at a peripheral portion where the core material 5 divided into a plurality of parts is arranged as a building material or a wall material such as a house. Moreover, before joining the panel 4 and the vacuum heat insulating material 1, you may incorporate as a wall material of a house, and may join together with a nail, a screw, etc. collectively. Moreover, instead of putting it in the house as the heat insulating panel 6, it is possible to use only the vacuum heat insulating material 1 joined to the wall material of the existing house.

以上のように、本実施の形態において、真空断熱材１はラミネートフィルム２の内部に複数個に分割した芯材５を周辺部に備え、その他の部分に芯材３を備え、面状のヒーター等によりそれぞれ個別に真空密封されたものであり、その複数個に分割した芯材５が多数配置された周辺部において、住宅の壁材として釘等により接合するので、釘等の接合において数個の真空が常圧に戻ってしまっても他の真空がリークすることがないので断熱性能に大きな影響がなく、またその他の部分に大きい芯材を配置しているので、芯材被覆率の低下による断熱性能の低下を抑えることができる。   As described above, in the present embodiment, the vacuum heat insulating material 1 includes the core material 5 divided into a plurality of parts inside the laminate film 2 in the peripheral portion, and includes the core material 3 in other portions, and is a planar heater. Each of them is vacuum-sealed individually, etc., and in the periphery where a large number of core materials 5 divided into a plurality are arranged, they are joined together with nails or the like as a wall material for a house. Even if the vacuum returns to normal pressure, no other vacuum leaks, so there is no significant effect on the heat insulation performance, and a large core material is placed in other parts, resulting in a decrease in core material coverage. It is possible to suppress a decrease in heat insulation performance due to.

また、周辺部に複数個に分割した芯材があるので、釘等で打てる個所が容易にわかり、接合し易くなる。また、容易に真空断熱材を壁材に適用することが可能となる。なお、複数個に分割した芯材５の大きさを小さくすると、ヒートリークが大きくなり断熱性能が低下するが、ラミネートフィルムの金属層を蒸着層にすることで、ガスバリア性の低下を抑えつつ、ヒートリークを小さくできるので、断熱性能の低下を抑えることができる。   In addition, since there is a core material divided into a plurality of parts in the peripheral part, it is easy to find a place where it can be hit with a nail or the like and it becomes easy to join. In addition, the vacuum heat insulating material can be easily applied to the wall material. In addition, if the size of the core material 5 divided into a plurality is reduced, the heat leak increases and the heat insulation performance decreases, but by making the metal layer of the laminate film a vapor deposition layer, while suppressing the decrease in gas barrier properties, Since heat leak can be reduced, it is possible to suppress a decrease in heat insulation performance.
