Description

【０００１】
【発明の属する技術分野】
本発明は、断熱パネルに係り、特に施工性の向上等を図った断熱パネルに関する。
【０００２】
【従来の技術】
建物としては、在来工法の軸組からなる躯体に、断熱パネルからなる壁パネルや屋根パネル等を取付けることにより、施工性の向上を図った木造建物が知られている。この建物に使用される断熱パネルは、枠組と、この枠組の両面に張り付けられた面材と、これら枠組と面材で区画された内部に設けられた断熱材とから構成されている。
【０００３】
この断熱パネルは、断熱性に優れているだけでなく、面材として構造用面材を使用することにより耐力壁となり、建物の強度の向上が図れる。壁パネルの場合、枠組を軸組間に挿入し、室外側の面材を軸組の室外面に当接させて取付けるように構成されており、枠組の周囲には軸組との間をシールする気密材が設けられている。この場合、気密材を枠組に両面テープで張り付け、更にステープルで補強するという取付構造が採用されていた。
【０００４】
【発明が解決しようとする課題】
しかしながら、前記断熱パネルにおいては、躯体に取付ける時に、気密材が躯体との摩擦抵抗や引っ掛かりにより、めくれたり、剥離したりしやすい。このため、取付けに手間がかかるという問題があった。
【０００５】
そこで、本発明は、上記事情を考慮してなされたもので、気密材のめくれや剥離を生じさせずに容易に取付けることができ、施工性の向上が図れる断熱パネルを提供することを目的とする。
【０００６】

【０００９】
【発明の実施の形態】
以下に、本発明の実施の形態を添付図面に基いて詳述する。
【００１０】
図１ないし図３において、１は木造の建物で、この建物１は躯体例えば在来工法の軸組２における壁部や屋根部に断熱パネルからなる壁パネル３や屋根パネル（図示省略）を取付けて構成されている。壁パネル３としては、方形の標準壁パネル、窓サッシ等を取付ける開口部を有する開口壁パネル、切妻壁部に取付けられる矢切りパネル等があるが、本実施の形態では基本的な標準壁パネルについて説明する。
【００１１】
前記壁パネル３は、図４にも示すように、枠材からなる上下の横枠４ａ，４ｂおよび左右の縦枠４ｃ，４ｄを方形に配して固着具例えば釘で組立てられた枠組（四方枠ともいう。）５と、この枠組５の両面に張り付けられる面材６ａ，６ｂと、これら枠組５と面材６ａ，６ｂで区画された内部に設けられた断熱材７と、枠組５の周囲に設けられ軸組２との間を気密にシールする気密材（断熱パッキンともいう。）８とから主に構成されている。
【００１２】
枠材は、例えばランバー材からなっている。枠組５内には、必要に応じて中間縦枠４ｅや中間横枠（図示省略）が設けられている。枠組５は、軸組２内、すなわち左右の柱２ａと上下の桁（梁、土台を含む。）２ｂで区画された内部に室外側から挿入されるようになっている。この場合、枠組５は、軸組２との間に上下左右にそれぞれ所定の隙間例えば７ｍｍ程度の隙間Ｓが形成される大きさに設計されている。
【００１３】
前記面材６ａ，６ｂは、耐力壁用の面材、例えば構造用合板、パーティクルボード、ＯＳＢ（オリエンテッド・ストランド・ボード）等からなっている。室外側の面材６ａは、枠組５よりも大きく形成されており、枠組５より張り出した鍔部６ｘを軸組２の室外面に当接させて固着具例えば釘で張り付け固定されるようになっている。前記面材６ａの鍔部６ｘには、軸組２との間を気密にシールするための気密シール材９が設けられていることが好ましい。なお、室内側の面材６ｂとしては、紙、シート等が用いられる場合があるが、本実施の形態では板材（合板）が用いられている。これらの面材６ａ，６ｂは、枠組に固着具例えばステープルで張り付けられることが好ましい。
【００１４】
断熱材７としては、枠組５と面材６ａ，６ｂで区画された内部に注入発泡により充填される例えば発泡ポリウレタンフォーム等の発泡断熱材であることが好ましい。発泡断熱材は、枠組５に設けられた注入口（図示省略）から注入される。
【００１５】
前記気密材８は、断面Ｌ字状の基部（ベース部）１０と、この基部１０の一片１０ａに設けられ軸組２との間を気密にシールする気密ヒレ１１ａ，１１ｂとから主に構成されている。基部１０は硬質合成樹脂例えば硬質塩化ビニルにより形成され、気密ヒレ１１ａ，１１ｂは軟質合成樹脂例えば軟質塩化ビニルにより形成されている。気密材８は、基部１０の他片１０ｂを枠組５と室内側面材６ｂの間に介在させ、この面材６ｂと共に固着具であるステープル１２にて枠組５に固着することにより取付けられている。
【００１６】
気密材８は、基部１０の一片１０ａと他片１０ｂを枠組５の側面と端面に当接させて枠組５の各辺の長手方向に沿って配置し、他片１０ｂを枠組５の端面に少量のステープルで予め仮止めし、次いで室内側面材６ｂの取付けと同時に本止めすることが上手に取付ける上で好ましい。なお、基部１０の一片１０ａもステープルで枠組５に適宜固定してもよい。
【００１７】
前記気密材８の基部１０の一片１０ａは、軸組２と対向しており、その一片１０ａに室内外方向に複数段（図示例では２段）となるように、複数（図示例では２枚）の気密ヒレ１１ａ，１１ｂが対向する軸組２と接するように室内側から室外側に向って斜め方向に突設されている。これら気密ヒレ１１ａ，１１ｂは、基部１０の一片１０ａに長手方向に連続して一体的に設けられている。また、気密ヒレ１１ａ，１１ｂは、基端部から先端部に向って漸次厚さ（肉厚）が薄くなるように形成されていることが好ましい。
【００１８】
前記気密ヒレ１１ａ，１１ｂのうち、室内側の一方の気密ヒレ１１ａの少なくとも先端側は、他方の気密ヒレ１１ｂの傾斜角度αよりも大きく室外側方向へ傾斜して形成されていることが施工時のめくれを防止する上で好ましい。この場合、図２に示すように、室外側の他方の気密ヒレ１１ｂは、基部１０の一片１０ａに垂直線に対して所定の角度α例えばα＝２２度程度で室外側へ傾斜して設けられており、室内側の一方の気密ヒレ１１ａの基端部が所定範囲ｗで他方の気密ヒレ１１ｂと略同じ傾斜角度で略平行に設けられ、その基端部から先端側が更に所定の角度β例えばβ＝８度程度で室外側に傾斜して形成されている。
【００１９】
前記一方の気密ヒレ１１ａにおける基端部の所定範囲ｗの寸法は、前記枠組５と軸組２の隙間Ｓと略同じ寸法例えば５ｍｍ程度であることが、基端部の腰の強さで隙間Ｓを確保する上で好ましい。また、気密ヒレ１１ａ，１１ｂの突出長さは、前記隙間Ｓよりも十分に広い寸法例えば１９ｍｍ程度とされていることが好ましい。
【００２０】
また、枠組５の少なくとも下辺（下横枠４ｂ）に設けられる気密材８においては、室内側の気密ヒレ１１ａが枠組５の室内端よりも室外側寄りに所定の寸法ｔ例えばｔ＝５ｍｍ程度後退させて設けられていることにより、前記基部１０に軸組２への仮置き部１３が形成されていることが好ましい。これにより、図５に示すように、施工時に重い壁パネル３を軸組２に一時的に仮置きしてから押し込むことにより容易に取付けることができるようになっている。
【００２１】
以上の構成からなる壁パネル３によれば、枠組５の周囲に設けられ建物１の躯体である軸組２との間をシールする気密材８が断面Ｌ字状の基部１０の一片１ａに気密ヒレ１１ａ，１１ｂを設け、基部１０の他片１０ｂを枠組５と面材６ｂの間に介在させ、面材６ｂと共に固着具例えばステープル１２にて枠組５に固着してなるため、気密材８の取付けが容易にできると共に、施工時の気密材８のめくれや剥離を防止でき、施工性の向上が図れる。すなわち、面材６ｂの取付けと同時に気密材８を取付ける（本止めする）ことができるため、気密材８の取付けが迅速かつ容易に行え、組立性の向上が図れる。また、壁パネル３を軸組２に取付ける場合、枠組５を軸組２内に挿入する時に枠組５の周囲に設けられている気密材８が軸組２に引っ掛かったり、抵抗を受けるが、気密材８の断面Ｌ字状の基部１０の一端（他片１０ｂ）が枠組５の挿入側の端面に固定されているため、基部１０がめくれたり、剥離したりすることがなく、耐久性の向上が図れると共に、壁パネル３の取付けが容易にでき、施工性の向上が図れる。
【００２２】
また、前記気密材８は、気密ヒレ１１ａ，１１ｂを枠組５の下辺（下横材４ｂ）の室内端よりも室外側寄りに設けることにより、基部１０に軸組２への仮置き部１３を形成しているため、施工時に前記仮置き部１３にて壁パネル３を軸組２に仮置きして壁パネル３を軸組２に容易に取付けることが可能となり、施工性の向上が図れる。すなわち、重い壁パネル３を一度に軸組２に取付けることは困難であるが、気密材８の基部１０に軸組２への仮置き部１３が形成されているため、図５に示すように、軸組（例えば土台）２に仮置きすることにより、壁パネル３の荷重を軸組２に預けることができると共に壁パネル３の左右方向の位置決めを容易に行うことができ、また、この状態から壁パネル３を押し込むことにより、枠組５を軸組２内に挿入して壁パネル３を容易に取付けることが可能となり、施工性の向上が図れる。
【００２３】
更に、前記気密材８は、室内側から室外側に向って斜め方向に複数の気密ヒレ１１ａ，１１ｂを有し、室内側の一方の気密ヒレ１１ａの少なくとも先端側が他方の気密ヒレ１１ｂの傾斜角度αよりも大きく室外側方向へ傾斜して形成されているため、軸組２内に枠組５を挿入する時の抵抗を低減することができると共に、施工時に発生しやすい気密ヒレ１１ａのめくれを防止でき、壁パネル３を躯体２に容易に取付けることが可能となり、施工性の向上が図れる。例えば図６に示すように、壁パネル３を先ず枠組５の下辺（下横枠４ｂ）が軸組２内に入るように傾斜させてから取付けようとした場合、その傾斜角度θが例えば最大３０度の場合でも、室内側気密ヒレ１１ａの先端側は軸組２の上面に対して最大でも垂直状態であるため、室外側気密ヒレ１１ｂの先端側が室内側に傾斜してめくれやすいのに対して、室内側気密ヒレ１１ａは室内側にめくれ難い。室内側気密ヒレ１１ａが室内側にめくれると、挿入抵抗が増大するだけでなく、室内側気密ヒレ１１ａが室内側に突出して見栄えが悪くなるという問題が生じるが、室内側気密ヒレ１１ａのめくれを防止できるため、このような問題を未然に防止することができる。
【００２４】
以上、本発明の実施の形態を図面により詳述してきたが、本発明は上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲での種々の設計変更等が可能である。例えば、枠組と面材で区画された内部に設けられる断熱材としては、注入発泡により充填される断熱材が好ましいが、予めブロック状に形成された定形断熱材であってもよい。本発明は、壁パネル以外に、例えば小屋パネルや屋根パネル等にも適用可能である。枠組に面材や気密材を固定する固着具としては、ステープルが好ましいが、釘等であってもよい。
【００２５】

[0015]
The airtight member 8 is mainly composed of a base portion (base portion) 10 having an L-shaped cross section and airtight fins 11a and 11b which are provided on one piece 10a of the base portion 10 and hermetically seal between the shaft assembly 2. ing. The base 10 is formed of a hard synthetic resin such as hard vinyl chloride, and the airtight fins 11a and 11b are formed of a soft synthetic resin such as soft vinyl chloride. The airtight member 8 is attached by interposing the other piece 10b of the base portion 10 between the frame 5 and the indoor side surface member 6b, and fixing the frame 10 together with the surface member 6b with the staple 12 as a fixing tool.
[0016]
The airtight member 8 is arranged along the longitudinal direction of each side of the frame 5 with the one piece 10a and the other piece 10b of the base 10 being brought into contact with the side surface and the end face of the frame 5, and a small amount of the other piece 10b is placed on the end face of the frame 5. It is preferable that the paper is temporarily fixed with the staples in advance, and then fixed at the same time as the attachment of the interior side surface material 6b for the good attachment. Note that the piece 10a of the base 10 may also be appropriately fixed to the frame 5 with staples.
[0017]
One piece 10a of the base 10 of the airtight member 8 is opposed to the shaft assembly 2, and a plurality of pieces (two pieces in the illustrated example) are provided so that the piece 10a has a plurality of steps (two steps in the illustrated example) in the indoor and outdoor directions. ) Airtight fins 11a and 11b are provided so as to project obliquely from the indoor side toward the outdoor side so as to be in contact with the opposing shaft assembly 2. These airtight fins 11a and 11b are integrally provided in one piece 10a of the base 10 continuously in the longitudinal direction. Moreover, it is preferable that the airtight fins 11a and 11b are formed so that the thickness (thickness) gradually decreases from the base end portion toward the tip end portion.
[0018]
Among the airtight fins 11a and 11b, at least the front end side of one airtight fin 11a on the indoor side is formed to be inclined in the outdoor direction larger than the inclination angle α of the other airtight fin 11b. It is preferable in preventing turning over. In this case, as shown in FIG. 2, the other airtight fin 11b on the outdoor side is provided on the piece 10a of the base 10 so as to be inclined to the outdoor side at a predetermined angle α, for example, α = 22 degrees. The base end portion of one airtight fin 11a on the indoor side is provided in a predetermined range w substantially in parallel with the other airtight fin 11b at the same inclination angle, and the tip end side further extends from the base end portion by a predetermined angle β. It is formed to be inclined to the outdoor side at about β = 8 degrees.

According to the wall panel 3 having the above-described configuration, the airtight member 8 provided around the frame 5 and sealing between the frame assembly 2 which is the housing of the building 1 is airtight in the piece 1a of the base 10 having an L-shaped cross section. Since the fins 11a and 11b are provided, and the other piece 10b of the base 10 is interposed between the frame 5 and the face material 6b, and is fixed to the frame 5 together with the face material 6b by a fixing tool, for example, staple 12, the airtight material 8 The mounting can be facilitated, and the airtight material 8 can be prevented from being turned over or peeled off during construction, thereby improving the workability. That is, since the airtight material 8 can be attached (fixed) at the same time as the face material 6b is attached, the airtight material 8 can be attached quickly and easily, and the assemblability can be improved. In addition, when the wall panel 3 is attached to the shaft assembly 2, when the frame assembly 5 is inserted into the shaft assembly 2, the airtight material 8 provided around the frame assembly 5 is caught by the shaft assembly 2 and receives resistance. Since one end (the other piece 10b) of the base portion 10 having the L-shaped cross section of the material 8 is fixed to the end surface on the insertion side of the frame 5, the base portion 10 is not turned over or peeled off, thereby improving durability. The wall panel 3 can be easily attached and the workability can be improved.
[0022]
In addition, the airtight material 8 is provided with the airtight fins 11a and 11b closer to the outdoor side than the indoor end of the lower side (lower horizontal member 4b) of the frame 5, thereby providing the base 10 with the temporary placement portion 13 for the shaft assembly 2. Since it is formed, the wall panel 3 can be temporarily placed on the shaft assembly 2 by the temporary placement portion 13 during construction, and the wall panel 3 can be easily attached to the shaft assembly 2, and workability can be improved. That is, although it is difficult to attach the heavy wall panel 3 to the shaft assembly 2 at a time, a temporary placement portion 13 for the shaft assembly 2 is formed at the base portion 10 of the airtight member 8, as shown in FIG. By temporarily placing on the shaft assembly (for example, the base) 2, the load of the wall panel 3 can be deposited on the shaft assembly 2, and the wall panel 3 can be easily positioned in the left-right direction. When the wall panel 3 is pushed in, the frame 5 can be inserted into the shaft assembly 2 and the wall panel 3 can be easily attached, and the workability can be improved.

Further, the airtight material 8 has a plurality of airtight fins 11a and 11b in an oblique direction from the indoor side toward the outdoor side, and at least the front end side of one airtight fin 11a on the indoor side is an inclination angle of the other airtight fin 11b. Since it is formed to be inclined in the outdoor direction larger than α, the resistance when inserting the frame 5 into the shaft assembly 2 can be reduced, and the airtight fin 11a which is likely to occur during construction is prevented from being turned over. This makes it possible to easily attach the wall panel 3 to the housing 2 and improve workability. For example, as shown in FIG. 6, when the wall panel 3 is first inclined so that the lower side (lower horizontal frame 4 b) of the frame 5 enters the shaft group 2, the inclination angle θ is, for example, 30 at the maximum. Even in the case of the degree, since the front end side of the indoor airtight fin 11a is at most perpendicular to the upper surface of the shaft assembly 2, the front end side of the outdoor airtight fin 11b tends to be inclined to the indoor side. The indoor airtight fin 11a is difficult to turn to the indoor side. If the indoor side airtight fin 11a is turned to the indoor side, not only will the insertion resistance increase, but there will be a problem that the indoor side airtight fin 11a protrudes into the indoor side and the appearance deteriorates, but the indoor side airtight fin 11a is turned over. Such a problem can be prevented in advance.
