Description

【０００１】
【発明の属する技術分野】
本発明は、建物における発泡樹脂断熱板の取付け方法及び取付け金物に関する。
【０００２】
【従来の技術】
ツーバイフォー工法などの建物において、例えば、屋外側に面する壁を断熱壁にする方法として、発泡樹脂断熱板を用い、これを屋外側からの釘打ちで下地に取り付ける方法がある。
【０００３】
しかしながら、断熱壁に用いられる発泡樹脂断熱板は、その肉厚寸法が例えば８０ｍｍと大きいため、長い釘を使用しなければならず、しかも、断熱板は発泡樹脂からなるので、釘打ちの途上で釘が座屈して曲がってしまうおそれがある。
【０００４】
本発明は、上記のような問題点に鑑み、発泡樹脂断熱板を釘に曲がりを生じさせることなく下地に取り付けることができる建物における発泡樹脂断熱板の取付け方法等を提供することを課題の一つとする。
【０００５】
【課題を解決するための手段】
上記の課題は、第１板部と第２板部とが発泡樹脂断熱板の肉厚寸法よりも小さい間隔寸法をおいて向き合うよう第３板部で連接されたコ字状部分を備え、第１板部に釘打ち孔が設けられると共に、第２板部に釘打ち孔と同心の釘受け孔が設けられた取付け金物を用い、
第１板部を発泡樹脂断熱板を挟んで下地とは反対側の面部に沿わせ、第２板部を発泡樹脂断熱板の肉厚方向中間部位置に配置するように、取付け金物を発泡樹脂断熱板の縁部にセットし、しかる後、
釘を、第１板部の側から釘打ち孔と釘受け孔に通し、下地に打ち込むことを特徴とする建物における発泡樹脂断熱板の取付け方法によって解決される。
【０００６】
この取付け方法では、発泡樹脂断熱板の肉厚方向中間部位置に取付け金物の第２板部が存在し、この第２板部に明けられた釘受け孔で釘の周囲を受け支えながら釘が下地に打ち込まれていくので、釘打ちの途上で釘が曲がってしまうのを防ぐことができる。
【０００７】
しかも、取付け金物には第１板部が備えられ、第１板部には釘打ち孔が明けられ、第２板部の釘受け孔は第１板部の釘打ち孔と同心であり、第１板部と第２板部との間には発泡樹脂断熱板の肉部が存在するだけであるから、釘打ちに際しては、釘を第１板部の釘打ち孔に真っ直ぐ刺し込むようにするするだけで容易に第２板部の釘受け孔に通すことができ、釘は、第２板部の釘受け孔に刺し込まれると第１板部と第２板部とで２点支持され、釘を安定良く真っ直ぐに下地に打ち込んでいくことができ、釘打ち作業を能率良く行っていくことができる。
【０００８】
上記の取付け方法において、発泡樹脂断熱板が屋外側に面する壁用のもので、上下方向において隣り合う発泡樹脂断熱板の突き合わせ部が屋外側を下段とする相欠き構造をしており、
取付け金物は、第１板部が上発泡樹脂断熱板の屋外側の面部に沿い、第３板部が相欠き構造部における下段部に沿い、第２板部が相欠き構造部における上下段間の立ち上がり部に沿うようになされていると共に、相欠き構造部における上段部に沿う第４板部と、第４板部の先端部から立ち上がる第５板部とを備えて、第５板部に止付け孔が第１板部よりも上方に位置して設けられたものからなっており、
釘又はネジを第５板部の止付け孔を通じて下地に打ち込み、第２板部で下発泡樹脂断熱板の上端の相欠き構造部における上下段間の立ち上がり部を支えるようにすることで下発泡樹脂断熱板の上端を取付け金物で下地に止め付け、しかる後、
上発泡樹脂断熱板を、下端の相欠き構造部における屋外側の突縁部を取付け金物の第１板部と第２板部と第３板部とに囲まれた内部に嵌め込んで下地に沿わせ、
釘を、第１板部の側から釘打ち孔と釘受け孔に通し、上発泡樹脂断熱板の下端突縁部と下発泡樹脂断熱板の上端突縁部とを貫通して下地に打ち込むようにするとよい。
【０００９】
この場合は、上下の発泡樹脂断熱板の突き合わせ部は屋外側を下段とする相欠き構造をしているので、取付け金物の第５板部の立ち上がり高さ寸法を低く抑えながら、その止付け孔を第１板部よりも上方に位置させることができて、止付け孔を通じた下地への釘又はネジの打込みを第１板部に妨げられることなく容易に行うことができると共に、第５板部の立ち上がり高さ寸法が低く抑えられることで下地への取付け金物の止付け状態、ひいては、下地への下発泡樹脂断熱板の止付け状態を安定したものにすることができる。また、この止付けに用いる釘又はネジは短尺なものでよく、止付けを容易に行っていくことができる。
【００１０】
更に、上発泡樹脂断熱板の下端は、相欠き構造部の屋外側の突縁部を取付け金物の第１板部と第２板部と第３板部とに囲まれた内部に嵌め込むようにするだけで位置決めされ、上発泡樹脂断熱板の組付けを容易に行っていくことができる。
【００１１】
しかも、下発泡樹脂断熱板の上端と上発泡樹脂断熱板の下端とを共通の長い釘で屋外側から同時に下地に取り付けることができて、上下の発泡樹脂断熱板の取付けを能率良く行っていくことができる。
【００１２】
また、上記の取付け方法において、取付け金物が、第４板部の先端部から垂れ下がる第６板部を備え、該第６板部と第４板部と第２板部とに囲まれた内部に下発泡樹脂断熱板の相欠き構造部における突縁部を嵌合させるようにして取付け金物を下発泡樹脂断熱板の上端に組み付けた後、釘又はネジを第５板部の止付け孔を通じて下地に打ち込み、下発泡樹脂断熱板の上端を取付け金物で下地に止め付けるようにするとよい。
【００１３】
この場合は、取付け金物を下発泡樹脂断熱板の上端に安定良く組み付けることができ、取付け金物を下発泡樹脂断熱板に保持させながら、下地への取付け金物の止付けと下地への取付け金物による下発泡樹脂断熱板上端部の止付けを施工容易に行っていくことができる。
【００１４】
また、上記の取付け方法において、取付け金物が、第４板部の先端部から垂れ下がる第６板部を備えると共に、第３板部の屋外側の縁部から垂れ下がる第７板部を備え、
第６板部と第４板部と第２板部とに囲まれた内部に下発泡樹脂断熱板の相欠き構造部における突縁部を嵌合させると共に、第７板部を下発泡樹脂断熱板の屋外側の面部に沿わせるようにして取付け金物を下発泡樹脂断熱板の上端に組み付けた後、釘又はネジを第５板部の止付け孔を通じて下地に打ち込み、下発泡樹脂断熱板の上端を取付け金物で下地に止め付けるようにするとよい。
【００１５】
この場合は、第２板部と第６板部を下発泡樹脂断熱板の相欠き構造部における突縁部が支え、更に、第６板部と第７板部とを下発泡樹脂断熱板上端の全厚さ部分が支えるので、取付け金物を下発泡樹脂断熱板により一層しっかりと保持させることができ、下地への取付け金物の止付けと下地への取付け金物による下発泡樹脂断熱板上端部の止付けを施工容易に行っていくことができる。
【００１６】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。
【００１７】
図１乃至図３に示す実施形態は、ツーバイフォー工法などによる住宅用建物の屋外側に面する壁を断熱壁にするための発泡樹脂断熱板の取付け方法についてのもので、１は下地、２は下発泡樹脂断熱板、３は上発泡樹脂断熱板、４は取付け金物である。
【００１８】
上下の発泡樹脂断熱板２，３は、発泡ポリウレタンや発泡ポリスチレンなどの樹脂発泡体からなっており、それらの厚さ寸法は例えば８０ｍｍであり、上下方向において隣り合わせられ、それらの突き合わせ部は、図１及び図２に示すように、屋外側を下段とする相欠き構造をしている。
【００１９】
取付け金物４は、ピース物で、金属板の曲げ一体成形品からなっており、第１板部５と第２板部６とが発泡樹脂断熱板の肉厚寸法よりも小さい間隔寸法、本実施形態では発泡樹脂断熱板の肉厚寸法の半分の間隔寸法をおいて向き合うよう第３板部７で連接されたコ字状部分を備え、第１板部５が上発泡樹脂断熱板３の屋外側の面部に沿い、第３板部７が相欠き構造部における下段部に沿い、第２板部６が相欠き構造部における上下段間の立ち上がり部に沿うようになされている。
【００２０】
更に、この取付け金物４には、相欠き構造部における上段部に沿う第４板部８と、第４板部８の先端部から立ち上がる第５板部９とが備えられ、また、第４板部８の先端部から垂れ下がる第６板部１０と、第３板部７の屋外側の縁部から垂れ下がる第７板部１１とが備えられている。
【００２１】
そして、第１板部５には釘打ち孔１２が設けられると共に、第２板部６には釘打ち孔１２と同心の釘受け孔１３が設けられ、更に、第５板部９には止付け孔１４が第１板部５よりも上方に位置して設けられている。
【００２２】
下地１への発泡樹脂断熱板２，３の取付けは、次のようにして行う。即ち、図３（イ）に示すように、まず、下発泡樹脂断熱板２の上端を取付け金物４を用いて下地１に止め付ける。止付けは、第５板部９の止付け孔１４を通じて釘１５又はネジを下地１に打ち込んで下地１に止め付けた取付け金物４の第２板部６で下発泡樹脂断熱板２の上端の相欠き構造部における上下段間の立ち上がり部を支えるようにする。
【００２３】
上下の発泡樹脂断熱板２，３の突き合わせ部は屋外側を下段とする相欠き構造をしているので、取付け金物４の第５板部９の立ち上がり高さ寸法を低く抑えながら、その止付け孔１４を第１板部５よりも上方に位置させることができ、そのため、止付け孔１４を通じた下地１への釘１５又はネジの打込みを第１板部５に妨げられることなく容易に行うことができると共に、第５板部９の立ち上がり高さ寸法が低く抑えられることで下地１への取付け金物４の止付け状態、ひいては、下地１への下発泡樹脂断熱板２の止付け状態を安定したものにすることができる。また、この止付けに用いる釘１５又はネジは短尺なものでよく、止付けを容易に行っていくことができる。
【００２４】
本実施形態では、取付け金物４に第２板部６のほか、第６板部１０と第７板部１１が備えられているので、第６板部１０と第４板部８と第２板部６とに囲まれた内部に下発泡樹脂断熱板２の相欠き構造部における突縁部２ａを嵌合させると共に、第７板部１１を下発泡樹脂断熱板２の屋外側の面部に沿わせるようにして取付け金物４を下発泡樹脂断熱板２の上端に組み付け、しかる後、下地１への取付け金物４の止付けを行うようにするとよい。
【００２５】
第２板部６が下発泡樹脂断熱板２の相欠き構造部における立ち上がり部を支え、第６板部１０が下発泡樹脂断熱板２の背面側を支え、第７板部１１が下発泡樹脂断熱板２の正面側を支えるので、下地止付け前の取付け金物４を下発泡樹脂断熱板２の上端に安定良く組み付けることができ、取付け金物４を下発泡樹脂断熱板２に保持させながら、下地１への取付け金物４の止付けと下地１への取付け金物４による下発泡樹脂断熱板２の上端部の止付けを施工容易に行っていくことができる。この場合、取付け金物４において第７板部１１は省略されてもよい。
【００２６】
なお、取付け金物４を下地１に止め付けた後に、取付け金物４の第６板部１０と第４板部８と第２板部６とに囲まれた内部に下発泡樹脂断熱板２の相欠き構造部における突縁部２ａを嵌合させると共に、第７板部１１を下発泡樹脂断熱板２の屋外側の面部に沿わせるようにして、下発泡樹脂断熱板２を下地１に止め付けるようにしてもよい。
【００２７】
こうして下地１への下発泡樹脂断熱板２の止付けを終えた後、図３（ロ）に示すように、上発泡樹脂断熱板３を、下端の相欠き構造部における屋外側の突縁部３ａを取付け金物４の第１板部５と第２板部６と第３板部７とに囲まれた内部に嵌め込んで下地１に沿わせる。
【００２８】
上発泡樹脂断熱板３の下端は、相欠き構造部の屋外側の突縁部３ａを取付け金物４の第１板部５と第２板部６と第３板部７とに囲まれた内部に嵌め込むようにするだけで位置決めされ、上発泡樹脂断熱板３の組付けを容易に行っていくことができる。
【００２９】
そして、図３（ロ）及び図２（ロ）に示すように、釘１６を、第１板部５の側から釘打ち孔１２と釘受け孔１３に通し、上発泡樹脂断熱板３の下端突縁部３ａと下発泡樹脂断熱板２の上端突縁部２ａとを貫通して下地１に打ち込む。
【００３０】
発泡樹脂断熱板２，３の肉厚方向中間部位置に取付け金物４の第２板部６が存在し、この第２板部６に明けられた釘受け孔１３で釘１６の周囲を受け支えながら釘１６が下地１に打ち込まれていくので、釘打ちの途上で釘１６が曲がってしまうことはない。
【００３１】
しかも、取付け金物４の第１板部５の釘打ち孔１２と、第２板部６の釘受け孔１３とは同心であり、第１板部５と第２板部６との間には上発泡樹脂断熱板３の肉部が存在するだけであるから、釘打ちに際しては、釘１６を第１板部５の釘打ち孔１２に真っ直ぐ刺し込むようにするするだけで容易に第２板部６の釘受け孔１３に通すことができると共に、釘１６は、第２板部６の釘受け孔１３に刺し込まれると第１板部５と第２板部６とで複数点支持され、釘１６を安定良く真っ直ぐに下地１に打ち込んでいくことができ、釘打ち作業を能率良く行っていくことができる。
【００３２】
更に、下発泡樹脂断熱板２の上端と上発泡樹脂断熱板３の下端とを共通の長い釘１６で屋外側から同時に下地１に取り付けることができて、上下の発泡樹脂断熱板２，３の取付けを能率良く行っていくことができる。
【００３３】
以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、発泡樹脂断熱板で屋外に面する壁を断熱壁にする場合を示したが、床を断熱床にする場合や天井を断熱天井にする場合などの発泡樹脂断熱板の取付けに用いることも可能である。また、下地への発泡樹脂断熱板の取付けは現場で行うようにしてもよいし、ユニット工法やパネル工法による建物の場合は工場で行うようにしてもよい。更に、建物は、発泡樹脂断熱板を取り付ける下地が釘打ちに適したもの、例えば木であればよく、建物自体は木造であるか鉄骨造であるかその他であるかは問わないし、建築の工法も問わない。また、取付け金物についても、第１板部と第２板部とが発泡樹脂断熱板の肉厚寸法よりも小さい間隔寸法をおいて向き合うよう第３板部で連接されたコ字状部分を少なくとも備え、第１板部に釘打ち孔が設けられると共に、第２板部に釘打ち孔と同心の釘受け孔が設けられたものであればよく、樹脂の一体成型品などからなっていてもよい。また、本発明は、隣り合う発泡樹脂断熱板の相欠き構造部における取付けに限らないし、隣り合う発泡樹脂断熱板をそれぞれの取付け金物で下地に取り付ける場合に用いることもできる。
【００３４】
【発明の効果】
本発明は、以上のとおりのものであるから、発泡樹脂断熱板を釘に曲がりを生じさせることなく下地に取り付けることができる等、種々の効果を発揮することができる。

BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0017]
The embodiment shown in FIGS. 1 to 3 relates to a method of attaching a foamed resin heat insulating plate for making a wall facing the outdoor side of a residential building into a heat insulating wall by a two-by-four construction method or the like. The lower foamed resin insulation board 3 is an upper foamed resin insulation board, and 4 is a mounting hardware.
[0018]
The upper and lower foamed resin heat insulating plates 2 and 3 are made of a resin foam such as foamed polyurethane or foamed polystyrene, and have a thickness dimension of, for example, 80 mm, and are vertically adjacent to each other. As shown in FIGS. 1 and 2, the open-ended structure has a chipped structure in which the outdoor side is a lower stage.
[0019]
The mounting hardware 4 is a piece and is formed by bending and integrally molding a metal plate. The distance between the first plate 5 and the second plate 6 is smaller than the thickness of the foamed resin insulation plate. In the embodiment, a U-shaped portion connected by a third plate portion 7 so as to face each other at an interval of a half of the thickness of the foamed resin heat insulating plate is provided, and the first plate portion 5 is a housing of the upper foamed resin heat insulating plate 3. Along the outer surface, the third plate portion 7 extends along the lower portion of the chipped structure portion, and the second plate portion 6 extends along the rising portion between the upper and lower steps in the chipped structure portion.
[0020]
Further, the metal fitting 4 is provided with a fourth plate portion 8 extending along an upper portion of the chipped structure portion, and a fifth plate portion 9 rising from the tip of the fourth plate portion 8. A sixth plate portion 10 hanging down from the tip of the portion 8 and a seventh plate portion 11 hanging down from the outdoor edge of the third plate portion 7 are provided.
[0021]
The first plate portion 5 is provided with a nailing hole 12, the second plate portion 6 is provided with a nail receiving hole 13 concentric with the nailing hole 12, and the fifth plate portion 9 is further provided with a stop. The attachment hole 14 is provided above the first plate portion 5.
[0022]
Attachment of the foamed resin heat insulating plates 2 and 3 to the base 1 is performed as follows. That is, as shown in FIG. 3A, first, the upper end of the lower foamed resin heat insulating plate 2 is fixed to the base 1 using the mounting hardware 4. The nails or screws are driven into the base 1 through the fixing holes 14 of the fifth plate 9 to fasten the upper end of the lower foamed resin insulation plate 2 with the second plate 6 of the mounting hardware 4 fixed to the base 1. The rising portion between the upper and lower stages in the phase-off structure is supported.
[0023]
