Description

本発明は、建物の壁や床、天井、屋根等に設置される断熱材、断熱材の設置構造および断熱材の設置方法に関する。 The present invention relates to a heat insulating material installed on a wall, floor, ceiling, roof or the like of a building, a heat insulating material installation structure, and a heat insulating material installation method.

近年、住宅の構築についてはその工業化が進み、例えば壁や床、屋根といった構成要素を予め工場にてパネル化しておき、施工現場でこれらの建築用パネルを組み立てることにより住宅を構築するパネル工法が一部に採用されている（例えば、特許文献１参照）。
そして、このパネル工法の場合、建築用パネルに合わせて所定の大きさに形成した断熱材を、複数の芯材を組んで枠状に形成されたパネルの内部中空部に配置する方法が多く採られる。そして、これらの断熱材は、例えばグラスウール等の軟質断熱材が多く用いられている。
特開平１０−２３８０１３号公報 In recent years, the construction of houses has been industrialized. For example, there is a panel method for building houses by building components such as walls, floors, and roofs at the factory in advance and assembling these building panels at the construction site. Some have been adopted (see, for example, Patent Document 1).
In the case of this panel method, there are many methods in which a heat insulating material formed in a predetermined size in accordance with a building panel is arranged in an inner hollow portion of a panel formed by combining a plurality of core materials. It is done. And as these heat insulating materials, soft heat insulating materials, such as glass wool, are often used, for example.
Japanese Patent Laid-Open No. 10-238013

ところで、上記のようなグラスウールは、ガラス繊維を綿状とし、所定の形状に整形したものであるが、直径４〜８μｍ程度のガラス繊維が皮膚に付着して刺激を与える場合がある。特に、パネル内部でのずり落ち防止等を考慮してグラスウールを配置するには、グラスウールを手作業で押し込むなどの作業によってパネルの内部中空部に十分に充填しなければならないため、作業者にとって取り扱いにくい場合があった。 By the way, the glass wool as described above is obtained by forming glass fiber into a cotton shape and shaping it into a predetermined shape. However, glass fiber having a diameter of about 4 to 8 μm may adhere to the skin and give irritation. In particular, in order to place glass wool in consideration of prevention of slipping inside the panel, it is necessary for the operator to fill the hollow interior of the panel sufficiently by manually pushing in the glass wool. It was sometimes difficult.

そこで、グラスウールに代わって、ウレタンフォームやスチレンフォーム等の硬質断熱材を使用したいという要望があった。このような硬質断熱材の場合、パネルの内部中空部の大きさに合わせてカットされた断熱材を予め用意しておき、これら断熱材を内部中空部に配置する方法や、または内部中空部の大きさに合わせて断熱材をカッター等によって切断し、この切断された断熱材を内部中空部に配置する方法が採用される。 Therefore, there has been a demand for using hard heat insulating materials such as urethane foam and styrene foam in place of glass wool. In the case of such a hard heat insulating material, a heat insulating material cut in accordance with the size of the inner hollow portion of the panel is prepared in advance, and a method of arranging these heat insulating materials in the inner hollow portion, or the inner hollow portion A method is adopted in which the heat insulating material is cut with a cutter or the like in accordance with the size, and the cut heat insulating material is disposed in the internal hollow portion.

ところが、このような方法を採用した場合、内部中空部の大きさはパネルの大きさによって様々であるため、複数の大きさの断熱材を予め用意しておくのに手間がかかったり、カッター等によって断熱材を複数の大きさに切断する手間がかかる場合がある。特に、断熱材の厚さや密度が大きくなると、断熱材を切断し難くなり、さらに切断作業に手間がかかるなどの問題があった。 However, when such a method is adopted, the size of the internal hollow portion varies depending on the size of the panel, so it takes time to prepare a plurality of heat insulating materials in advance, a cutter, etc. May take time to cut the heat insulating material into a plurality of sizes. In particular, when the thickness and density of the heat insulating material are increased, it is difficult to cut the heat insulating material, and further, there is a problem that the cutting work is troublesome.

本発明の課題は、建物の壁や床等に断熱材を設置する際の手間を省略することが可能な断熱材、断熱材の設置構造および断熱材の設置方法を提供することを目的とする。 An object of the present invention is to provide a heat insulating material, a heat insulating material installation structure, and a heat insulating material installation method capable of omitting troubles when installing the heat insulating material on a wall or floor of a building. .

請求項１に記載の発明は、例えば図１および図２に示すように、建物の壁や床、天井、屋根等に設置される断熱材２において、
この断熱材２の厚さ方向に直交する一面側２ａおよび他面側２ｂに、これら一面側２ａおよび他面側２ｂから内側に向かって交互にスリット３を形成することによって、幅方向に沿って弾性伸縮可能となっていることを特徴とする。 The invention according to claim 1 is, for example, as shown in FIGS. 1 and 2, in a heat insulating material 2 installed on a wall, floor, ceiling, roof, etc. of a building,
By forming slits 3 alternately on the one surface side 2a and the other surface side 2b orthogonal to the thickness direction of the heat insulating material 2 from the one surface side 2a and the other surface side 2b inward, along the width direction. It is characterized by being elastically stretchable.

請求項１に記載の発明によれば、前記断熱材２は、この断熱材２の厚さ方向に直交する一面側２ａおよび他面側２ｂから内側に向かって交互にスリット３を形成することによって、幅方向に沿って弾性伸縮可能となっているので、これらスリット３を開放状態とすることによって、前記断熱材２を幅方向に沿って伸長させることができ、これらスリット３を閉塞状態とすることによって、前記断熱材２を幅方向に沿って収縮させることができる。これによって、従来とは異なり、パネルの大きさに応じた複数の断熱材を用意したり、断熱材の切断作業をする必要がなくなるので、建物の壁や床等に断熱材２を設置する際の手間を省略することが可能となる。 According to invention of Claim 1, the said heat insulating material 2 forms the slit 3 alternately from the one surface side 2a orthogonal to the thickness direction of this heat insulating material 2, and the other surface side 2b toward the inner side. Since the elastic expansion and contraction is possible along the width direction, the heat insulating material 2 can be extended along the width direction by opening the slits 3 so that the slits 3 are closed. Thus, the heat insulating material 2 can be contracted along the width direction. As a result, unlike conventional ones, it is not necessary to prepare a plurality of heat insulating materials according to the size of the panel or to cut the heat insulating materials. Therefore, when installing the heat insulating material 2 on the wall or floor of the building, etc. It becomes possible to omit the trouble.

請求項２に記載の発明は、例えば図１および図２に示すように、請求項１に記載の断熱材２の設置構造において、
前記断熱材２の一面側２ａから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも他面側２ｂに位置し、前記断熱材２の他面側２ｂから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも一面側２ａに位置していることを特徴とする。 The invention according to claim 2 is the installation structure of the heat insulating material 2 according to claim 1, for example, as shown in FIGS.
The front end 3a of the slit 3 formed inward from the one surface side 2a of the heat insulating material 2 is located on the other surface side 2b with respect to the intermediate portion in the thickness direction of the heat insulating material 2, and the other surface of the heat insulating material 2 The tip 3a of the slit 3 formed inward from the side 2b is characterized by being located on the one surface side 2a with respect to the intermediate portion in the thickness direction of the heat insulating material 2.

請求項２に記載の発明によれば、前記断熱材２の一面側２ａから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも他面側２ｂに位置し、前記断熱材２の他面側２ｂから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも一面側２ａに位置しているので、これらスリット３の寸法を、スリット３の先端部３ａが断熱材２の厚さ方向中間部を越えるように長くとることができる。これによって、例えばスリット３の先端部３ａが断熱材２の厚さ方向中間部を越えない場合に比して、断熱材２を幅方向に沿って伸長させた際のスリット３の開放幅が大きくなるので、断熱材２を十分に伸長させることができる。 According to the invention described in claim 2, the tip 3 a of the slit 3 formed inward from the one surface 2 a of the heat insulating material 2 is located on the other surface side 2 b than the intermediate portion in the thickness direction of the heat insulating material 2. Since the tip 3a of the slit 3 formed toward the inside from the other surface side 2b of the heat insulating material 2 is located on the one surface side 2a than the intermediate portion in the thickness direction of the heat insulating material 2, The dimensions of the slits 3 can be made long so that the tip 3 a of the slit 3 exceeds the intermediate part in the thickness direction of the heat insulating material 2. Thereby, for example, the opening width of the slit 3 when the heat insulating material 2 is extended along the width direction is larger than when the tip portion 3a of the slit 3 does not exceed the intermediate portion in the thickness direction of the heat insulating material 2. Therefore, the heat insulating material 2 can be fully extended.

請求項３に記載の発明は、例えば図１および図２に示すように、請求項１または２に記載の断熱材２の設置構造において、
前記スリット３は、前記断熱材２の一面側２ａおよび他面側２ｂから内側に向かって先鋭に形成されていることを特徴とする。 The invention according to claim 3 is the installation structure of the heat insulating material 2 according to claim 1 or 2, as shown in FIGS. 1 and 2, for example.
The slit 3 is formed so as to be sharpened inward from the one surface side 2a and the other surface side 2b of the heat insulating material 2.

請求項３に記載の発明によれば、前記スリット３は、前記断熱材２の一面側２ａおよび他面側２ｂから内側に向かって先鋭に形成されていることから、例えば先端が平面状に形成されたスリット（図示せず）の場合とは異なり、断熱材２を幅方向に沿って収縮させた際に、これらスリット３を隙間無く確実に閉塞状態とすることができるので、断熱材２を十分に収縮させることができる。 According to the invention described in claim 3, the slit 3 is formed so as to be sharpened inward from the one surface side 2 a and the other surface side 2 b of the heat insulating material 2. Unlike the case of the slits (not shown) made, when the heat insulating material 2 is contracted along the width direction, these slits 3 can be surely closed without gaps. Can be fully contracted.

また、従来とは異なり、パネルの大きさに応じた複数の断熱材を用意したり、断熱材の切断作業をする必要がなくなるので、建物を構成する建築用パネル１０に断熱材２を設置する際の手間を省略することができる。 According to the invention described in claim 4, the building panel 10 is attached to a frame body 11 in which a plurality of core members 1, 1...

Therefore, since the heat insulating material 2 can be reliably held between the core materials 1 and 1, the heat insulating material 2 can be reliably installed on the building panel 10.
Also, unlike conventional ones, it is not necessary to prepare a plurality of heat insulating materials according to the size of the panel or to cut the heat insulating materials, so the heat insulating materials 2 are installed on the building panel 10 constituting the building. It is possible to save time and effort.

請求項５に記載の発明は、例えば図１および図２に示すように、建物を構成する建築用パネル１０に、請求項１〜３のいずれか一項に記載の断熱材２を設置する断熱材２の設置方法であって、
前記建築用パネル１０を、複数の芯材１，１…を矩形枠状に組んで枠体１１を形成するとともに、この枠体１１の一方の表面に面材１２を取り付けて内部中空部１３を有する状態に形成しておき、
前記断熱材２を、前記内部中間部１３を介して隣り合う芯材１，１間の寸法に応じて伸長または収縮させるとともに、これら芯材１，１の両対向面１ｃ，１ｃに、断熱材２の両側端面２ｃ，２ｃを固着するようにして、前記内部中空部１３に配置することを特徴とする。 Invention of Claim 5 is the heat insulation which installs the heat insulating material 2 as described in any one of Claims 1-3 in the panel 10 for construction which comprises a building, for example, as shown in FIG. 1 and FIG. A method for installing the material 2,
The building panel 10 is formed by assembling a plurality of core members 1, 1... Into a rectangular frame shape to form a frame body 11, and a face material 12 is attached to one surface of the frame body 11 to form an internal hollow portion 13. Formed to have a state,

The two side end faces 2c, 2c are fixed to the inner hollow portion 13 so as to be fixed.

請求項５に記載の発明によれば、前記断熱材２を、前記建築用パネル１０の内部中空部１３を介して隣り合う芯材１，１間の寸法に応じて伸長または収縮させるとともに、これら芯材１，１の両対向面１ｃ，１ｃに、断熱材２の両側端面２ｃ，２ｃを固着するだけで、前記内部中空部１３に配置することができるので、この断熱材２を、前記芯材１，１間に確実に保持することができ、前記断熱材２を、前記建築用パネル１０に対して確実かつ容易に設置することができる。
また、従来とは異なり、パネルの大きさに応じた複数の断熱材を用意したり、断熱材の切断作業をする必要がなくなるので、建物を構成する建築用パネル１０に断熱材２を設置する際の手間を省略することができる。 According to invention of Claim 5, while extending | stretching or shrinking | contracting the said heat insulating material 2 according to the dimension between the adjacent core materials 1 and 1 via the internal hollow part 13 of the said panel 10 for construction, these Since the both end surfaces 2c, 2c of the heat insulating material 2 can be fixed to the opposing surfaces 1c, 1c of the core material 1, 1, the heat insulating material 2 can be disposed in the inner hollow portion 13.

It is possible to save time and effort.

本発明によれば、建物の壁や床、天井、屋根等に設置される断熱材は、この断熱材の厚さ方向に直交する一面側および他面側から内側に向かって交互にスリットを形成することによって、幅方向に沿って弾性伸縮可能となっているので、これらスリットを開放状態とすることによって、断熱材を幅方向に沿って伸長させることができ、これらスリットを閉塞状態とすることによって、断熱材を幅方向に沿って収縮させることができる。これによって、従来とは異なり、パネルの大きさに応じた複数の断熱材を用意したり、断熱材の切断作業をする必要がなくなるので、建物の壁や床等に断熱材を設置する際の手間を省略することが可能となる。

Since the elastic expansion and contraction is possible along the width direction, the heat insulating material can be extended along the width direction by opening the slits, and the slits are closed. Thus, the heat insulating material can be contracted along the width direction. As a result, unlike conventional ones, there is no need to prepare multiple insulation materials according to the size of the panel or to cut the insulation material, so when installing insulation materials on the walls or floors of buildings, etc. It is possible to save labor.

以下、図面を参照して本発明の実施の形態について説明する。なお、本実施の形態の断熱材は、壁や床、屋根といった建物の構成要素を予め工場にてパネル化しておき、施工現場でこれらの建築用パネルを組み立てて建物を構築するようなパネル工法に用いられるが、従来の軸組工法や壁式工法の木造、鉄骨造、鉄筋コンクリート造等の各建物・各工法にも用いることができる。 Embodiments of the present invention will be described below with reference to the drawings. In addition, the heat insulating material of the present embodiment is a panel method in which building components such as walls, floors, and roofs are panelized in advance in the factory, and these building panels are assembled at the construction site to construct the building. However, it can also be used for each building and each construction method such as a conventional wooden frame construction method and a wall construction method, such as wooden construction, steel construction, and reinforced concrete construction.

本実施の形態の断熱材２は、図１および図２に示すように、建物の壁や床、天井、屋根等に設置されるものであり、この断熱材２の厚さ方向に直交する一面側２ａおよび他面側２ｂに、これら一面側２ａおよび他面側２ｂから内側に向かって交互にスリット３を形成することによって、幅方向に沿って弾性伸縮可能となっている。 As shown in FIGS. 1 and 2, the heat insulating material 2 according to the present embodiment is installed on a wall, floor, ceiling, roof, or the like of a building, and is one surface orthogonal to the thickness direction of the heat insulating material 2. By alternately forming slits 3 on the side 2a and the other surface side 2b from the one surface side 2a and the other surface side 2b toward the inside, it is possible to elastically expand and contract along the width direction.

前記断熱材２は、例えばウレタンフォームやスチレンフォーム等の硬質断熱材が用いられており、元々平面視矩形状であった硬質断熱材に、図１に示すように、この硬質断熱材の厚さ方向に直交する一面側２ａおよび他面側２ｂから内側に向かって交互にスリット３を形成するようにして構成されている。 As the heat insulating material 2, for example, a hard heat insulating material such as urethane foam or styrene foam is used, and the thickness of the hard heat insulating material as shown in FIG. The slits 3 are alternately formed inward from the one surface side 2a and the other surface side 2b orthogonal to the direction.

そして、前記断熱材２は、この断熱材２の厚さ方向に直交する一面側２ａおよび他面側２ｂから内側に向かって交互に形成されたスリット３を、それぞれ開放状態とすることによって、断熱材２を幅方向に沿って伸長させることができ、これらスリット３をそれぞれ閉塞状態とすることによって、断熱材２を幅方向に沿って収縮させることができるようになっている。これによって、本実施の形態の断熱材２は、その幅方向に沿って弾性伸縮可能となっている。 And the said heat insulating material 2 heat-insulates by making the slit 3 alternately formed toward the inner side from the one surface side 2a and the other surface side 2b orthogonal to the thickness direction of this heat insulating material 2, respectively. The material 2 can be extended | stretched along the width direction, and the heat insulating material 2 can be shrunk | contracted along the width direction by making these slits 3 each a closed state. Thereby, the heat insulating material 2 of this Embodiment can be elastically expanded-contracted along the width direction.

また、前記スリット３は、前記断熱材２に対して複数形成されており、その形成された数量に応じて断熱材２の伸縮範囲を変更することができるようになっており、適宜変更可能であることは言うまでもない。 In addition, a plurality of the slits 3 are formed with respect to the heat insulating material 2, and the expansion / contraction range of the heat insulating material 2 can be changed according to the number of the slits 3 formed. Needless to say.

さらに、図１および図２に示すように、前記断熱材２の一面側２ａから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも他面側２ｂに位置し、前記断熱材２の他面側２ｂから内側に向かって形成されたスリット３の先端部３ａは、断熱材２の厚さ方向中間部よりも一面側２ａに位置している。 Further, as shown in FIGS. 1 and 2, the tip 3 a of the slit 3 formed inward from the one surface 2 a of the heat insulating material 2 is on the other surface side than the intermediate portion in the thickness direction of the heat insulating material 2. The tip 3 a of the slit 3 that is located at 2 b and formed inward from the other surface side 2 b of the heat insulating material 2 is located on the one surface side 2 a than the intermediate portion in the thickness direction of the heat insulating material 2.

すなわち、前記断熱材２の一面側２ａから内側に向かって形成されたスリット３の先端部３ａを、断熱材２の厚さ方向中間部よりも他面側２ｂに位置させ、前記断熱材２の他面側２ｂから内側に向かって形成されたスリット３の先端部３ａを、断熱材２の厚さ方向中間部よりも一面側２ａに位置させることで、これらスリット３の寸法を、スリット３の先端部３ａが断熱材２の厚さ方向中間部を越えるように長くとることができる。
これによって、例えばスリット３の先端部３ａが断熱材２の厚さ方向中間部を越えない場合に比して、断熱材２を幅方向に沿って伸長させた際のスリット３の開放幅が大きくなるので、断熱材２を十分に伸長させることが可能となる。 That is, the front end portion 3a of the slit 3 formed from the one surface side 2a of the heat insulating material 2 toward the inside is positioned on the other surface side 2b with respect to the intermediate portion in the thickness direction of the heat insulating material 2, and the heat insulating material 2 By positioning the tip portion 3a of the slit 3 formed inward from the other surface side 2b on the one surface side 2a with respect to the intermediate portion in the thickness direction of the heat insulating material 2, the dimensions of these slits 3 can be adjusted. The tip portion 3a can be long so as to exceed the intermediate portion in the thickness direction of the heat insulating material 2.
Thereby, for example, the opening width of the slit 3 when the heat insulating material 2 is extended along the width direction is larger than when the tip portion 3a of the slit 3 does not exceed the intermediate portion in the thickness direction of the heat insulating material 2. Therefore, the heat insulating material 2 can be sufficiently extended.

つまり、このようにスリット３を、その先端が断熱材２の厚さ方向中間部を超えるように長く形成することによって、前記断熱材２を、例えばスリット３の先端部３ａが断熱材２の厚さ方向中間部を越えない場合に比して、より大きな蛇行形状となるように形成できるようになっている。 That is, the slit 3 is formed long so that the tip thereof exceeds the intermediate portion in the thickness direction of the heat insulating material 2, so that the heat insulating material 2 is formed such that the tip 3 a of the slit 3 has the thickness of the heat insulating material 2. Compared to the case where the intermediate portion in the vertical direction is not exceeded, it can be formed to have a larger meander shape.

一方、前記スリット３は、前記断熱材２の一面側２ａおよび他面側２ｂから内側に向かって先鋭に形成されており、例えば先端が平面状に形成されたスリット（図示せず）の場合とは異なり、断熱材２を幅方向に沿って収縮させた際に、これらスリット３を隙間無く確実に閉塞状態とすることができるので、断熱材２を十分に収縮させることができるようになっている。 On the other hand, the slit 3 is formed sharply inward from the one surface side 2a and the other surface side 2b of the heat insulating material 2, for example, in the case of a slit (not shown) whose tip is formed in a flat shape. On the other hand, when the heat insulating material 2 is contracted along the width direction, the slits 3 can be reliably closed without any gaps, so that the heat insulating material 2 can be sufficiently contracted. Yes.

なお、図示はしないが、例えばスリットの先端部が平面状に形成されると、断熱材２を幅方向に沿って収縮させた際に、スリットの先端部付近を完全に閉塞しにくくなって空隙が生じてしまったり、断熱材２の表面が歪んでしまったりする場合がある。 Although not shown, for example, when the tip of the slit is formed in a flat shape, when the heat insulating material 2 is contracted along the width direction, the vicinity of the tip of the slit is hardly completely blocked, and the gap May occur, or the surface of the heat insulating material 2 may be distorted.

以上のようにして、本実施の形態の断熱材２は、図２（ａ），（ｂ）に示すように、その幅方向に沿って弾性伸縮可能となっている。 As described above, as shown in FIGS. 2A and 2B, the heat insulating material 2 of the present embodiment can be elastically expanded and contracted along its width direction.

なお、前記断熱材２の一面側２ａから内側に向かって形成されたスリット３の数量と、前記断熱材２の他面側２ｂから内側に向かって形成されたスリット３の数量は同一であることが望ましい。 In addition, the quantity of the slit 3 formed toward the inside from the one surface side 2a of the heat insulating material 2 and the number of the slit 3 formed toward the inside from the other surface side 2b of the heat insulating material 2 are the same. Is desirable.
