Such a vacuum heat insulating material has been conventionally used in refrigerators and the like, but as described in Patent Document 1, attempts have been made in recent years to be used for heat insulating structures for buildings. However, in the heat insulating structure as described in Patent Document 1, since the vacuum heat insulating material is used as it is, the vacuum heat insulating material may be damaged and the vacuum may be broken.

それに対して、特許文献２では、真空断熱材の損傷を防止するために、真空断熱材に緩衝材を貼り合わせた冷蔵庫用の断熱材を開示している。また、特許文献３は、真空断熱材の損傷を防ぐために、真空断熱材を発泡断熱板でサンドイッチした断熱パネルを含む、屋根用の断熱構造体を開示している。ここでは、断熱積層体とはめ込む枠体との間に、衝撃緩衝材を充填してもよいとしている。   On the other hand, in patent document 2, in order to prevent damage to a vacuum heat insulating material, the heat insulating material for refrigerators which bonded the buffer material to the vacuum heat insulating material is disclosed. Moreover, in order to prevent damage to a vacuum heat insulating material, patent document 3 is disclosing the heat insulation structure for roofs containing the heat insulation panel which sandwiched the vacuum heat insulating material with the foam heat insulating board. Here, it is assumed that an impact cushioning material may be filled between the heat insulating laminate and the frame to be fitted.

また、特許文献４においても、壁面に設置された横胴縁に弾性充填材を設け、そして真空断熱材を弾性充填材に押し込みながら横胴縁間に取り付けた真空断熱材の設置構造体を開示している。   Also, Patent Document 4 discloses a vacuum heat insulating material installation structure in which an elastic filler is provided on a horizontal trunk edge installed on a wall surface, and the vacuum heat insulating material is attached between the horizontal trunk edges while being pushed into the elastic filler. doing.

特許文献３に記載の断熱パネルは、真空断熱材の損傷を一定程度防ぐことができるが、衝撃緩衝材を、真空断熱材とは別に設置する必要があるため、施工に手間が掛かるという課題があった。また、特許文献４に記載の構造体では、真空断熱材が損傷を受ける可能性があり、また壁面の横胴縁に弾性充填材を設置する必要があるため、施工に手間が掛かるという課題があった。   Although the heat insulation panel of patent document 3 can prevent damage to a vacuum heat insulating material to some extent, since it is necessary to install an impact buffering material separately from a vacuum heat insulating material, the subject that construction takes time will be taken. there were. In addition, in the structure described in Patent Document 4, there is a possibility that the vacuum heat insulating material may be damaged, and it is necessary to install an elastic filler on the lateral trunk edge of the wall surface, so that there is a problem that it takes time for construction. there were.

そこで、本発明は、高い断熱性を有し、損傷を受けにくく、かつ施工が容易である、真空断熱材を含む断熱パネル及びその施工方法を与えることを目的とする。   Then, an object of this invention is to provide the heat insulation panel containing a vacuum heat insulating material which has high heat insulation, is hard to receive a damage, and is easy to construct, and its construction method.

《断熱パネル》
本発明の断熱パネルは、芯材及び芯材を封入している外皮を有する真空断熱材、並びに真空断熱材を包囲している緩衝材シートを含む。 《Insulation panel》
The heat insulating panel of the present invention includes a vacuum heat insulating material having a core material and a skin enclosing the core material, and a cushioning material sheet surrounding the vacuum heat insulating material.

本発明の断熱パネルは、緩衝材シートが存在していることで、真空断熱材が損傷を受けにくい。そのため、本発明の断熱パネルは取扱いが容易である。また、本発明の断熱パネルは、真空断熱材を含むことから非常に高い断熱性を有し、それによって小さな厚みで断熱性の優れた断熱層を構成することができ、例えば住宅の壁構造体の一部に本発明の断熱パネルを用いた場合に、広い居住空間を住宅に与えることができる。さらに、本発明の断熱パネルは、緩衝材シートの弾性に起因して、施工時に支持部材にはめ込むだけで容易に固定することができる。   In the heat insulating panel of the present invention, the vacuum heat insulating material is not easily damaged due to the presence of the buffer material sheet. Therefore, the heat insulation panel of the present invention is easy to handle. In addition, since the heat insulation panel of the present invention includes a vacuum heat insulating material, the heat insulation panel has a very high heat insulation property, and thereby can form a heat insulation layer having a small thickness and an excellent heat insulation property. For example, a wall structure of a house When the heat insulation panel of the present invention is used as a part of the housing, a wide living space can be given to the house. Furthermore, due to the elasticity of the cushioning material sheet, the heat insulation panel of the present invention can be easily fixed simply by fitting into the support member during construction.

図１は、本発明の断熱パネルの一実施態様の断面図を例示している。本発明の断熱パネル（１０）は、芯材（１ａ）及び芯材（１ａ）を封入している外皮（１ｂ）を有する真空断熱材（１）、並びに真空断熱材（１）を包囲している緩衝材シート（２）を含む。   FIG. 1 illustrates a cross-sectional view of one embodiment of the thermal insulation panel of the present invention. The heat insulation panel (10) of the present invention surrounds the vacuum insulation (1) having the core (1a) and the outer skin (1b) enclosing the core (1a), and the vacuum insulation (1). A cushioning sheet (2).

本発明の断熱パネルにおいて、真空断熱材の全体を緩衝材シートが包囲している必要はなく、真空断熱材は一部が外部に露出していてもよい。ただし、緩衝材シートは、本発明の断熱パネルの施工時に真空断熱材が損傷を受けにくいように真空断熱材を包囲しており、また本発明の断熱パネルが支持部材間にはめ込んで固定できるような弾性部分を与えるように、真空断熱材を包囲している。例えば、真空断熱材が２つの主平面及び２組の対向する側面を含む６つの面を有する場合、緩衝材シートは、真空断熱材の２つの主平面と、少なくとも１組の対向する側面を覆っていればよく、この場合、真空断熱材の側面を覆った緩衝材シートの弾性を利用して、本発明の断熱パネルは、支持部材間に固定することができる。   In the heat insulating panel of the present invention, the entire vacuum heat insulating material does not have to be surrounded by the buffer material sheet, and a part of the vacuum heat insulating material may be exposed to the outside. However, the cushioning material sheet surrounds the vacuum heat insulating material so that the vacuum heat insulating material is not easily damaged during the construction of the heat insulating panel of the present invention, and the heat insulating panel of the present invention can be fitted and fixed between the support members. The vacuum insulation is surrounded so as to provide an elastic part. For example, if the vacuum insulation has six faces including two major planes and two sets of opposing sides, the cushioning sheet covers the two major planes of the vacuum insulation and at least one set of opposite sides. In this case, the heat insulation panel of the present invention can be fixed between the support members by using the elasticity of the cushioning material sheet covering the side surface of the vacuum heat insulation material.

１枚の緩衝材シートで真空断熱材を包囲して断熱パネルを構成する場合、緩衝材シートを折り曲げて真空断熱材を包囲した後に、シートの端部を互いに固定する必要があるが、その固定は、接着剤、接着テープ、熱融着等によって行うことができる。２枚の緩衝材シートで真空断熱材をサンドイッチして断熱パネルを構成する場合にも、緩衝材シートの端部を同様の手段で固定することができる。   When a heat insulating panel is constructed by surrounding a vacuum heat insulating material with a single cushioning material sheet, it is necessary to fix the end portions of the sheets to each other after folding the buffering material sheet to surround the vacuum heat insulating material. Can be performed by an adhesive, an adhesive tape, heat fusion, or the like. Even when sandwiching a vacuum heat insulating material between two buffer material sheets to form a heat insulating panel, the end of the buffer material sheet can be fixed by the same means.

本発明の断熱パネルは、主平面が略長方形であってもよい。その面方向の１辺の長さは、例えば５０ｍｍ以上、１００ｍｍ以上、１５０ｍｍ以上、２００ｍｍ以上、又は３００ｍｍ以上であってもよく、１５００ｍｍ以下、１２００ｍｍ以下、１０００ｍｍ以下、８００ｍｍ以下、６００ｍｍ以下、又は４００ｍｍ以下であってもよい。また、厚みは、５ｍｍ以上、８ｍｍ以上、１０ｍｍ以上、又は１５ｍｍ以上であってもよく、１００ｍｍ以下、８０ｍｍ以下、６０ｍｍ以下、５０ｍｍ以下、４０ｍｍ以下、３０ｍｍ以下、２５ｍｍ以下、又は２０ｍｍ以下であってもよい。好ましくは、本発明の断熱パネルは、３０ｍｍ以下又は２５ｍｍ以下の厚みを有する。   The heat insulation panel of the present invention may have a substantially rectangular main plane. The length of one side in the surface direction may be, for example, 50 mm or more, 100 mm or more, 150 mm or more, 200 mm or more, or 300 mm or more, 1500 mm or less, 1200 mm or less, 1000 mm or less, 800 mm or less, 600 mm or less, or 400 mm. It may be the following. The thickness may be 5 mm or more, 8 mm or more, 10 mm or more, or 15 mm or more, and is 100 mm or less, 80 mm or less, 60 mm or less, 50 mm or less, 40 mm or less, 30 mm or less, 25 mm or less, or 20 mm or less. Also good. Preferably, the heat insulation panel of the present invention has a thickness of 30 mm or less or 25 mm or less.

本発明の断熱パネルは、例えば、建築物の壁構造体の一部に用いることができ、特に外張断熱工法を用いた建築物の付加断熱材として好適に用いることができる。   The heat insulation panel of the present invention can be used, for example, as a part of a wall structure of a building, and can be suitably used as an additional heat insulating material for a building using an external heat insulation method.

例えば外張断熱工法を用いた住宅の壁は、図２に示すような層構造を有する場合がある。すなわち、外張断熱工法を用いた住宅の壁は、屋内側から屋外側へと、壁紙が貼られる石膏ボード等である内壁材（１１）、ポリエチレンシート等の気密性の防湿シート（１２）、柱又は間柱（１３）間の第１の断熱材（１３ａ）、構造用合板（１４）、水平方向の支持部材（いわゆる横胴縁）（１５）間の第２の断熱材（１５ａ）、透湿防水性シート（１６）、鉛直方向の構造部材（いわゆる通気胴縁）（１７）によって形成される通気層（１７ａ）、及び外壁材又はサイディング（１８）を有する場合がある。ここで、第２の断熱材は、付加断熱材と呼ばれる。   For example, a wall of a house using an external thermal insulation method may have a layer structure as shown in FIG. That is, the wall of the house using the external thermal insulation method is an interior wall material (11) such as a plaster board on which wallpaper is pasted from the indoor side to the outdoor side, an airtight moisture-proof sheet (12) such as a polyethylene sheet, A first heat insulating material (13a) between pillars or studs (13), a structural plywood (14), a second heat insulating material (15a) between horizontal support members (so-called lateral trunk edges) (15), It may have a moisture and waterproof sheet (16), a vent layer (17a) formed by a vertical structural member (so-called ventilator edge) (17), and an outer wall material or siding (18). Here, the second heat insulating material is called an additional heat insulating material.

横胴縁（１５）間に付加断熱材（１５ａ）を施工する場合には、横胴縁（１５）間に付加断熱材（１５ａ）を入れた後に、通常は、プラスチックバンド等で付加断熱材（１５ａ）を固定し、その後に透湿防水性シート（１６）を施工する必要がある。   When constructing the additional heat insulating material (15a) between the horizontal trunk edges (15), after adding the additional heat insulating material (15a) between the horizontal trunk edges (15), the additional heat insulating material is usually formed with a plastic band or the like. It is necessary to fix (15a) and then construct a moisture permeable waterproof sheet (16).

また、横胴縁（１５）は、構造用合板（１４）等に固定されるが、付加断熱材（１５ａ）の厚みを大きくしようとすると、横胴縁（１５）の厚みも同時に大きくする必要があり、横胴縁（１５）が非常に重くなるため、構造用合板（１４）の強度が問題となる。   Further, the horizontal trunk edge (15) is fixed to the structural plywood (14) or the like. However, if the thickness of the additional heat insulating material (15a) is to be increased, the thickness of the horizontal trunk edge (15) must be increased at the same time. Since the horizontal trunk edge (15) becomes very heavy, the strength of the structural plywood (14) becomes a problem.

本発明の断熱パネルは、比較的薄くても非常に高い断熱性があるため、外張断熱工法の付加断熱材として用いた場合には、横胴縁の厚みも薄くすることができ、構造用合板の強度も問題となりにくい。そして、本発明の断熱パネルは、プラスチックバンド等の追加の固定部剤を使用することなく、横胴縁間にはめ込んで固定することができるため、施工が非常に容易である。   The heat insulating panel of the present invention has a very high heat insulating property even if it is relatively thin. Therefore, when used as an additional heat insulating material for an outer heat insulating method, the thickness of the lateral trunk edge can be reduced, The strength of plywood is not a problem. And since the heat insulation panel of this invention can be inserted and fixed between horizontal trunk edges, without using additional fixing parts agents, such as a plastic band, construction is very easy.

この場合、支持部材間の間隔は、支持部材に支持される方向についての断熱パネル内の真空断熱材の寸法よりも大きくてもよい。また、支持部材間の間隔は、支持部材に支持される方向についてのはめ込む前の状態の断熱パネルの寸法よりも小さくてもよい。上記のようなはめ込む前の状態の断熱パネルの寸法（Ａ）に対する支持部材間の間隔（Ｂ）の比（Ｂ／Ａ）は、０．９０以上、０．９５以上、０．９７以上、０．９８以上、０．９９以上、０．９９５以上であってもよく、１．０以下、０．９９５以下、０．９９以下、０．９８以下、０．９７以下、０．９５以下であってもよい。また、支持部材間の間隔（Ｂ）に対する断熱パネル内の真空断熱材の寸法（Ｃ）の比（Ｃ／Ｂ）も、０．９０以上、０．９５以上、０．９７以上、０．９８以上、０．９９以上、０．９９５以上であってもよく、１．０以下、０．９９５以下、０．９９以下、０．９８以下、０．９７以下、０．９５以下であってもよい。   In this case, the space | interval between support members may be larger than the dimension of the vacuum heat insulating material in the heat insulation panel about the direction supported by the support member. Moreover, the space | interval between support members may be smaller than the dimension of the heat insulation panel of the state before fitting about the direction supported by a support member. The ratio (B / A) of the interval (B) between the support members to the dimension (A) of the heat insulating panel in the state before fitting is 0.90 or more, 0.95 or more, 0.97 or more, 0 .98 or more, 0.99 or more, 0.995 or more, 1.0 or less, 0.995 or less, 0.99 or less, 0.98 or less, 0.97 or less, 0.95 or less May be. Further, the ratio (C / B) of the dimension (C) of the vacuum heat insulating material in the heat insulating panel to the distance (B) between the support members is also 0.90 or more, 0.95 or more, 0.97 or more, 0.98. Above, 0.99 or more, 0.995 or more, 1.0 or less, 0.995 or less, 0.99 or less, 0.98 or less, 0.97 or less, 0.95 or less Good.

この施工方法では、構造体の支持部材間の間隔よりもわずかに大きな断熱パネルを用意して、緩衝材シートを変形させることで、追加の固定部材を用いることなく支持部材に固定することができる。また、断熱パネルは緩衝材シートに覆われているため、断熱パネルが損傷を受けにくく、取扱いに細心の注意は必要がない。したがって、この施工方法は、非常に容易に行うことができる。   In this construction method, by preparing a heat insulation panel slightly larger than the interval between the support members of the structure and deforming the cushioning material sheet, it can be fixed to the support member without using an additional fixing member. . Moreover, since the heat insulation panel is covered with the cushioning material sheet, the heat insulation panel is not easily damaged, and careful handling is not necessary. Therefore, this construction method can be performed very easily.

構造体の支持部材は、断熱パネルを断熱する対象に固定するための部材であり、例えば構造体が住宅の壁である場合には、支持部材としては横胴縁を挙げることができる。支持部材の材料としては、建築材料として知られている材料であれば特に限定されないが、例えば木材、金属材料等であってもよい。特に、本発明の施工方法では、外張断熱工法における付加断熱材を与えるために好適に用いることができる。   The support member of the structure is a member for fixing the heat insulation panel to an object to be insulated. For example, when the structure is a wall of a house, the support member may include a horizontal trunk edge. The material of the support member is not particularly limited as long as it is a material known as a building material, but may be wood, a metal material, or the like, for example. In particular, in the construction method of the present invention, it can be suitably used for providing an additional heat insulating material in the external heat insulating method.
