Description

【0001】
【発明の属する技術分野】
本発明は、住宅等の建築物の気密構造、特に額縁廻りの気密構造に関するものである。
【0002】
【従来の技術】
近年、住宅には、計画的な換気による住宅の快適性の向上や、断熱性の向上による省エネルギー化を図るために、住宅の気密が求められるようになってきている。一般に、気密住宅とは、気密性能を表す相当隙間面積が床面積1平方メートル当たり5平方センチメートル以下のものをいい、これを達成するために、住宅の内部空間全体を気密面で囲うように気密工法が施工される。該気密工法は、住宅内部の隙間部分、例えば、額縁廻りにおいては、額縁、内壁枠等の接続部分にウレタン等の樹脂を吹き付けることにより、額縁廻りの気密を確保していた。
【0003】
【発明が解決しようとする課題】
しかし、前記気密工法においては、発泡したウレタンが、直射日光や夏期などで高温となった場合に、さらに発泡して膨張することがあるため、ウレタンを吹付けた接続部分が変形する等の問題があった。
本発明は、前記の点に鑑みてなされたものであり、住宅等の額縁廻りの気密を確保し、かつ、施工が容易な気密構造を提供することを目的とする。
【0004】
【課題を解決するための手段】
前記目的を達成するためになされた本発明の請求項1に係る額縁廻りの気密構造は、額縁と、該額縁が配設されるべき開口を有する内壁枠とを備えてなる額縁廻りの気密構造であって、前記額縁の外周面に、その一の面が前記内壁枠の表面と略同一面となるように周設された補助部材と、前記額縁廻りに沿って、前記補助部材の一の面と前記内壁枠の表面とに渡って貼設された帯状の気密テープとを備えてなるものである。
【0005】
また、本発明の請求項2に係る額縁廻りの気密構造は、額縁と、該額縁が配設されるべき開口を有する内壁枠とを備えてなる額縁廻りの気密構造であって、前記額縁廻りに沿って、該額縁の外周面及び前記内壁枠の表面と密接するように設けられたL型の気密プレートと、該気密プレートの継目部分を密封するように設けられた帯状の気密テープとを備えてなるものである。
【0006】
【発明の実施の形態】
以下、本発明の第1の実施の形態を図面に基づき具体的に説明する。
図1は、本発明の第1の実施の形態に係る額縁廻りの気密構造を説明するための概略斜視図である。図に示すように、窓1は、壁の開口に設けられており、窓1の屋内側には、矩形の額縁3が配設されている。さらに、窓1の屋内側の壁面には、石膏ボード4が覆設されている。
【0007】
図2は、図1におけるA−A断面を示す断面図である。図に示すように、軸組6に沿って、屋外側には外壁パネル5が、屋内側には断熱内壁枠2が、両者が互いに平行になるように設けられ、さらに、断熱内壁枠2の屋内側には石膏ボード4が配設されており、これらにより、住宅の壁が構成されている。該壁の開口の上下部分には、窓台15(図示せず)及び窓まぐさ16(図示せず)が配設されており、窓1は、該窓台15及び窓まぐさ16に固定された矩形の窓枠10と、ヒンジ12を介して屋外側に開閉する扉11とからなるものであり、扉11には、ガラス13が嵌め込まれている。窓1が設けられた壁の屋内側には、額縁3が配設されるべき開口23を有する断熱内壁枠2aが配設されており、該断熱内壁枠2aの開口周部24と窓枠10の周縁部14との間に、額縁3が配設されている。額縁3の外周面には、補助部材31が周設されており、該補助部材31と断熱内壁枠2aの表面との間を密封するように気密テープ7が貼り付けられている。
なお、窓枠10及び扉11の材質は特に限定されるものはなく、アルミニウムやステンレス製のものであっても、ポリ塩化ビニル等のプラスチック製のものであってもよいが、住宅内部の気密を確保するためには、窓1自体が気密を確保できるものであることが必要である。
【0008】
図3は、前記断熱内壁枠2aの詳細な構成を示す概略斜視図であり、説明の便宜上、気密シート22を省略したものを示している。図に示すように、断熱内壁枠2aは、縦桟と横桟とを組み合わせた矩形の枠体20に、適宜、補強部材を架設し、該枠体20の内部にグラスウール等の断熱材21を充填し、さらに、その表面には、気密を確保するためのポリプロピレン製の気密シート22(図示せず)を覆設したものであり、この気密シート22により、住宅内部の気密を確保するための気密面が形成される。また、窓1の屋内側に配設される内壁枠には、額縁3が配設されるべき開口23が設けられている。
【0009】
額縁3は、図4に示すように、断熱内壁枠2aの開口23の縦寸法又は横寸法と略同寸法の板状体を縦横に組み合わせた矩形の枠体であり、断熱内壁枠2aの開口周部24に配設されるものである。また、額縁3の外周面には、補助部材31が周設されている。該補助部材31は、その側面が、断熱内壁枠2aと額縁3との間の隙間を密封する気密テープ7を貼り付けるための貼りしろの役割を果たすものである。
該補助部材31は、図5に示すように、矩形の額縁3の一辺を担うL型の板32と同じ長さの平板であり、接着剤及び釘等で該板32に固定される。このとき、補助部材31の厚さ寸法が、前記気密テープ7の貼りしろ寸法となる。また、補助部材31の幅寸法、及び前記板32に固定される位置は、額縁3廻りに配設される石膏ボード4の厚さに対応して決定する。額縁3廻りの気密を確保する気密テープ7の貼付け施工を容易なものとするためには、気密テープ7の貼りしろとなるべき補助部材31の側面が、断熱内壁枠2aの開口23に額縁3を配設した場合に、該断熱内壁枠2aの表面と略同一面となるように、前記補助部材31の固定位置を決定することが望ましい。
なお、額縁3に補助部材31を周設する代わりに、額縁3の外周面に凹型溝を周設することとしてもよい。
【0010】
気密テープ7は、ポリエチレン、ポリプロピレン等の合成樹脂からなる帯状のものであり、その一の面には接着剤等が塗布されており、必要に応じて現場で適当な長さに裁断して用いられる。気密テープ7の材質は前記に限定されるものではないが、住宅の気密を確保するに十分な気密性、防湿性を有することが必要であり、さらに、施工や取扱いを容易なものとするために、適度な軟性を有するものであることが望ましい。
【0011】
以下、本気密構造の施工方法について、図6から図10に基づいて説明する。まず、図6に示すように、軸組6に沿って外壁パネル5、窓台15及び窓まぐさ16を取り付け、窓台15及び窓まぐさ16に窓1を固定する。窓1は、窓1全体を固定しても、窓1から扉11を取り除いた窓枠10のみを固定し、以下に説明する施工を終えてから、扉11を取り付けることとしてもよい。
さらに、図7に示すように、屋内側から、額縁3が配設されるべき開口23を有する断熱内壁枠2aを取り付ける。断熱内壁枠2、2aの継目部分は、必要に応じて、気密テープ7等を用いて密封し、気密を確保しておく。
【0012】
つぎに、図8に示すように、断熱内壁枠2aの開口23に、額縁3を嵌め込んで固定する。額縁3の固定は、ビスや釘等を、額縁3を貫通して断熱内壁枠2aの開口周部24に貫入するように打ち付けることにより、又は、適当な取付け金具等を用いて行う。
なお、必要であれば、窓枠10の周縁部14に、ポリウレタンやポリスチレン等の発泡体(図示せず)を周設し、額縁3を、該気密発泡体を押圧するように配設して、窓枠10と額縁3との間の気密を確保する。
【0013】
つぎに、額縁3廻りに気密テープ7を貼り付けるが、気密テープ7の貼付け方法は、図8に示す箇所Bを例に説明する。
気密テープ7は、図9に示すように、矩形の額縁3の各辺それぞれについて、その一の側縁を額縁3の補助部材31の側壁に、他の側縁を断熱内壁枠2aの表面に密接するように貼りつける。該補助部材31の側壁と断熱内壁枠2aの表面とは略同一面となっているので、気密テープ7を折り曲げることなく貼り付けることができる。
さらに、額縁3の隅部においては、図10に示すように、気密テープ7同士が相互に重なり合うように貼り付ける。額縁3の四隅すべてにおいて、これと同様に気密テープ7を貼りつける。このようにして、額縁3廻りの断熱内壁枠2aと額縁3との間の隙間を、気密テープ7により密封する。
その後、断熱内壁枠2aの屋内側に、石膏ボード4を、額縁3と補助部材31との間に嵌合するようにして覆設する。
なお、気密テープ7は、断熱内壁枠2aの表面に覆設された気密シート22に密着するように貼り付ければ気密を確保できるが、断熱内壁枠2aの枠体20又は桟がある位置までに渡って貼り付けられるような幅寸法の気密テープ7を用いて、該気密テープ7が、その後に覆設する石膏ボード4と断熱内壁枠2aの枠体等により挟み込まれるようにすれば、さらに確実に気密を保持することができる。
【0014】
このように、本実施の形態に係る額縁廻りの気密構造によれば、断熱内壁枠2aの開口周部24と窓枠10の周縁部14との間に配設される額縁3の外周面に、補助部材31を周設し、該補助部材31と断熱内壁枠2aの表面との間を密封するように気密テープ7を貼り付けるので、額縁廻りの住宅の気密を簡便に確保することができる。
【0015】
以下、本発明の第2の実施の形態を図面に基づき具体的に説明する。
図11は、本発明の第2の実施の形態に係る額縁廻りの気密構造を説明するための断面図であり、図1におけるA−A断面と同位置の断面を示すものである。図に示すように、軸組6に沿って、屋外側には外壁パネル5が、屋内側には断熱内壁枠2が、両者が互いに平行になるように設けられ、さらに、断熱内壁枠2の屋内側には石膏ボード4が配設されており、これらにより、住宅の壁が構成されている。該壁の開口の上下部分には、窓台15(図示せず)及び窓まぐさ16(図示せず)が配設されており、窓1は、該窓台15及び窓まぐさ16に固定された矩形の窓枠10と、ヒンジ12を介して屋外側に開閉する扉11とからなるものであり、扉11には、ガラス13が嵌め込まれている。窓1が設けられた壁の屋内側には、額縁3が配設されるべき開口を有する断熱内壁枠2aが配設されており、該断熱内壁枠2aの開口周部24と窓枠10の周縁部14との間に、額縁3が配設されている。また、額縁3の外周面と断熱内壁枠2aの表面との間には、L型の気密プレート8が設けられている。
なお、本実施の形態においても、窓枠10及び扉11の材質は特に限定されるものはなく、アルミニウムやステンレス製のものであっても、ポリ塩化ビニル等のプラスチック製のものであってもよいが、住宅内部の気密を確保するためには、窓1自体が気密を確保できるものであることが必要である。
【0016】
額縁3は、前記第1の実施の形態と同様に、断熱内壁枠2aの開口周部24に配設されるものであり、該額縁3の外周面には、図12に示すように、矩形の額縁3の各辺ごとに気密プレート8が密着して固定されている。
【0017】
気密プレート8は、図13に示すように、L型に曲折された板状体であり、その材質は、ポリプロピレン等の合成樹脂であっても、アルミニウム製又はステンレス製、その他金属製のものであってもよい。気密プレート8の長手方向の長さは、額縁3の縦方向又は横方向の長さと略同寸法のものである。
【0018】
以下、本気密構造の施工方法について、図14及び図15に基づいて説明する。
外壁パネル5、窓1、断熱内壁枠2、額縁3等の取付け方法は、前記第1の実施の形態と同様である。即ち、軸組6に沿って外壁パネル5、窓台15及び窓まぐさ16を取り付け、窓台15及び窓まぐさ16に窓1を固定し、さらに、屋内側から、前記開口23を有する断熱内壁枠2aを取り付け、該開口23に、額縁3を嵌め込んで固定する。
なお、額縁3の固定は、ビスや釘等を、額縁3を貫通して断熱内壁枠2aの開口周部24に貫入するように打ち付けることにより、又は、適当な取付け金具等を用いて行うものとし、必要であれば、窓枠10の周縁部14に、ポリウレタンやポリスチレン等の発泡体を周設し、額縁3を、該気密発泡体を押圧するように配設して、窓枠10と額縁3との間の気密を確保する。
【0019】
額縁3廻りには、図14に示すように、気密プレート8が取り付けれらるが、該気密プレート8の取付けは、額縁3を断熱内壁枠2aに配設する前に行っても、その後に行ってもよい。前記気密プレート8は、矩形の額縁3の各辺それぞれについて、そのL型の一の面を額縁3の外周面に、他の面を断熱内壁枠2aの表面に密接するように取り付けられる。このとき、気密プレート8の額縁3の外周面と密接すべき面には、予め接着剤等を塗布しておくか、両面テープを貼りつけておき、これらにより、気密プレート8を、額縁3の外周面の所定の位置に固定する。
つぎに、図15に示すように、気密プレート8と断熱内壁枠2aとの継目部分及び気密プレート8同士の継目部分に、気密テープ7を貼りつけて密封する。このとき、気密テープ7同士がそれぞれ重なるように貼り付け、気密プレート8と断熱内壁枠2aとの継目部分及び気密プレート8同士の継目部分に隙間やピンホールが生じないようにする。その後、断熱内壁枠2、2aの屋内側に、石膏ボード4を覆設する。
なお、この場合も前記第1の実施の形態と同様に、気密テープ7又は気密プレート8を、断熱内壁枠2aの枠体20又は桟がある位置までに渡って設ければ、さらに確実に気密を保持することができる。
【0020】
このように、本実施の形態に係る窓廻りの気密構造によれば、断熱内壁枠2aの開口周部24と窓枠10の周縁部14との間に配設された額縁3の外周面と、断熱内壁枠2aの表面との間に、L型の気密プレート8を設け、気密プレート8と断熱内壁枠2aとの継目部分及び気密プレート8同士の継目部分に、気密テープ7を貼りつけて密封したので、額縁廻りの住宅の気密を簡便に確保することができる。
【0021】
なお、前記第2の実施の形態では、気密プレート8と断熱内壁枠2aとの継目部分は、気密テープ7を貼り付けることにより密封するものとしたが、気密プレート8の、断熱内壁枠2aと密接する面に接着剤等を塗布して、気密プレートと断熱内壁枠2aとの継目部分を密封するものとしてもよい。
【0022】
また、前記各実施の形態では、窓枠と同形状の開口を有する内壁枠は、断熱材21が充填された断熱内壁枠2aとしたが、断熱材21が設けられていないような内壁枠を用いたとしても、本気密構造を利用することができる。
【0023】
【発明の効果】
以上説明したように、本発明の請求項1に係る額縁廻りの気密構造によれば、額縁の外周面に、その一の面が前記内壁枠の表面と略同一面となるように周設された補助部材と、前記額縁廻りに沿って、前記補助部材の一の面と前記内壁枠の表面とに渡って貼設された帯状の気密テープとを備えてなるものとしたので、額縁廻りにおける住宅の気密を簡便に確保することができる。
【0024】
また、本発明の請求項2に係る額縁廻りの気密構造によれば、額縁廻りに沿って、該額縁の外周面及び内壁枠の表面と密接するように設けられたL型の気密プレートと、該気密プレートの継目部分を密封するように設けられた帯状の気密テープとを備えてなるものとしたので、額縁廻りにおける住宅の気密を簡便に確保することができる。

It is prepared.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a schematic perspective view for explaining an airtight structure around a frame according to the first embodiment of the present invention. As shown in the figure, the window 1 is provided in the opening of the wall, and a rectangular frame 3 is disposed on the indoor side of the window 1. Furthermore, a gypsum board 4 is covered on the wall surface of the window 1 on the indoor side.
[0007]
FIG. 2 is a cross-sectional view showing an AA cross section in FIG. 1. As shown in the figure, along the shaft set 6, an outer wall panel 5 is provided on the outdoor side, a heat insulating inner wall frame 2 is provided on the indoor side so that they are parallel to each other. A gypsum board 4 is arranged on the indoor side, and these constitute a wall of the house. A window base 15 (not shown) and a window lintel 16 (not shown) are disposed at the upper and lower portions of the opening of the wall, and the window 1 is fixed to the window pedestal 15 and the window lintel 16. The rectangular window frame 10 and a door 11 that opens and closes outdoors via a hinge 12, and a glass 13 is fitted into the door 11. On the indoor side of the wall on which the window 1 is provided, a heat insulating inner wall frame 2a having an opening 23 in which the frame 3 is to be disposed is disposed. The opening peripheral portion 24 of the heat insulating inner wall frame 2a and the window frame 10 are disposed. The frame 3 is disposed between the peripheral edge 14 of the frame. An auxiliary member 31 is provided around the outer peripheral surface of the frame 3, and an airtight tape 7 is attached so as to seal between the auxiliary member 31 and the surface of the heat insulating inner wall frame 2a.
The material of the window frame 10 and the door 11 is not particularly limited, and may be made of aluminum or stainless steel or plastic such as polyvinyl chloride. In order to ensure this, it is necessary for the window 1 itself to be able to ensure airtightness.
[0008]
FIG. 3 is a schematic perspective view showing a detailed configuration of the heat insulating inner wall frame 2a, and shows the airtight sheet 22 omitted for convenience of explanation. As shown in the figure, the heat insulating inner wall frame 2a is constructed by appropriately installing a reinforcing member on a rectangular frame 20 in which a vertical beam and a horizontal beam are combined, and a heat insulating material 21 such as glass wool is provided inside the frame body 20. Further, the surface is covered with a polypropylene airtight sheet 22 (not shown) for ensuring airtightness, and the airtight sheet 22 is used for ensuring airtightness inside the house. An airtight surface is formed. Further, an opening 23 in which the frame 3 is to be disposed is provided in an inner wall frame disposed on the indoor side of the window 1.
[0009]
As shown in FIG. 4, the frame 3 is a rectangular frame obtained by vertically and horizontally combining plate-like bodies having substantially the same dimensions as the vertical dimension or horizontal dimension of the opening 23 of the heat insulating inner wall frame 2 a, and the opening of the heat insulating inner wall frame 2 a. It is disposed on the peripheral portion 24. An auxiliary member 31 is provided around the outer peripheral surface of the frame 3. The side surface of the auxiliary member 31 serves as a margin for attaching an airtight tape 7 that seals the gap between the heat insulating inner wall frame 2a and the frame 3.
As shown in FIG. 5, the auxiliary member 31 is a flat plate having the same length as the L-shaped plate 32 that bears one side of the rectangular frame 3, and is fixed to the plate 32 with an adhesive, a nail, or the like. At this time, the thickness dimension of the auxiliary member 31 becomes the pasting dimension of the airtight tape 7. Further, the width dimension of the auxiliary member 31 and the position fixed to the plate 32 are determined according to the thickness of the gypsum board 4 disposed around the frame 3. In order to facilitate the application of the airtight tape 7 that secures the airtightness around the frame 3, the side surface of the auxiliary member 31 that should be attached to the airtight tape 7 is connected to the opening 23 of the heat insulating inner wall frame 2 a. It is desirable to determine the fixing position of the auxiliary member 31 so that the auxiliary member 31 is substantially flush with the surface of the heat insulating inner wall frame 2a.
Instead of providing the auxiliary member 31 around the frame 3, a concave groove may be provided around the outer peripheral surface of the frame 3.
[0010]
The airtight tape 7 is a belt-shaped tape made of a synthetic resin such as polyethylene or polypropylene, and one surface of which is coated with an adhesive or the like. It is done. The material of the airtight tape 7 is not limited to the above, but it is necessary to have sufficient airtightness and moistureproofness to ensure the airtightness of the house, and to facilitate construction and handling. In addition, it is desirable to have moderate flexibility.
[0011]
Hereinafter, the construction method of this airtight structure is demonstrated based on FIGS. 6-10. First, as shown in FIG. 6, the outer wall panel 5, the window base 15 and the window lintel 16 are attached along the shaft set 6, and the window 1 is fixed to the window base 15 and the window lintel 16. Even if the window 1 is fixed to the entire window 1, only the window frame 10 obtained by removing the door 11 from the window 1 is fixed, and after the construction described below is completed, the door 11 may be attached.
Furthermore, as shown in FIG. 7, the heat insulation inner wall frame 2a which has the opening 23 by which the frame 3 should be arrange | positioned is attached from the indoor side. The joint portions of the heat insulating inner wall frames 2 and 2a are sealed with an airtight tape 7 or the like as necessary to ensure airtightness.
[0012]
Next, as shown in FIG. 8, the frame 3 is fitted and fixed in the opening 23 of the heat insulating inner wall frame 2a. The frame 3 is fixed by hitting a screw, a nail or the like so as to penetrate the frame 3 and penetrate into the opening peripheral portion 24 of the heat insulating inner wall frame 2a, or using an appropriate mounting bracket or the like.
If necessary, a foam (not shown) such as polyurethane or polystyrene is provided around the peripheral edge 14 of the window frame 10, and the frame 3 is disposed so as to press the airtight foam. The airtightness between the window frame 10 and the frame 3 is ensured.
[0013]
Next, the airtight tape 7 is attached around the frame 3. The method of attaching the airtight tape 7 will be described with reference to the location B shown in FIG.
As shown in FIG. 9, the airtight tape 7 has one side edge for each side of the rectangular frame 3 on the side wall of the auxiliary member 31 of the frame 3 and the other side edge on the surface of the heat insulating inner wall frame 2a.
