Description

【0001】
【発明の属する技術分野】
この発明は、建物の窓枠や戸枠などの開口部の密閉構造及びその製造方法に関する。
【0002】
【従来の技術】
従来より、建物の外壁部に窓や出入り口などを設ける場合、開口部の端縁部には、窓枠や戸枠などの枠体を組み込んで施工するのが一般的である。そのため、これらの開口部と枠体との間には隙間が発生しやすい。
【0003】
ここで、このような開口部と枠体との間の隙間を発泡性樹脂の発泡体で充填した密閉構造が提案されている(例えば、特許文献1参照。)。
【0004】
この特許文献1に記載の発明によれば、図1に示すように、構造用の面材7、内装下地材8及び外壁材9等からなる建物壁体に開口部1が設けられ、その開口部1の周縁に木質の角材2を設け、同角材2に枠体としてのアルミサッシ3を室外A側から取り付けている。
【0005】
ついで、開口部1の室内B側にアルミサッシ3の表面を隠すように角材2とは隙間を空けて化粧材4を沿設するとともにその隙間に発泡性樹脂の発泡体5を充填させている。そして、この発泡体5として、例えば、ウレタン樹脂材料を用いることにより、ウレタン樹脂材料が発泡して固化するときの自己接着性にて、化粧材4、角材2及びアルミサッシ3を発泡体5により一体化させることにより密閉構造が得られている。その後、発泡体5の屋内B面側は額縁材6により化粧されている。
【0006】
【特許文献1】
特開2000−240357号公報
【0007】
【発明が解決しようとする課題】
しかしながら、上記の特許文献1に記載の密閉構造は、アルミサッシ3を屋外側から取り付けた密閉構造のみを開示しており、その他の構造については具体的な開示していない。
【0008】
また、上記の特許文献1に記載の密閉構造は、アルミサッシ3の冷却による結露発生を低減することを目的としており、アルミサッシ3の室内側の表面は、化粧材4、発泡体5、額縁材6などで覆い隠され、これによりアルミサッシ3の室内側の結露が防止されている。
【0009】
このような構造では、アルミサッシ3の室内側が他の部材で覆い隠される必要があるので、例えば、外観を考慮した木製サッシなどに適用すると木製サッシが化粧材4等の他の部材により覆い隠されてしまい、木製サッシの外観をそのまま活用することができない。
【0010】
そこで、この発明は、外観美麗なサッシなどにも適用できる建物開口部の密閉構造及びその製造方法を提供することを目的とする。
【0011】
【課題を解決するための手段】
前記課題を解決するため、本発明は、建物開口部の内周面に所定の隙間を空けて配設された枠体と、該枠体の屋外側に配設された前記隙間の屋外側を閉塞する閉塞部材とを備え、前記建物開口部と枠体と閉塞部材とにより形成された空間に発泡性樹脂が充填されて発泡体が形成されていることを特徴とする建物開口部の密閉構造である。
【0012】
このように構成することにより、建物開口部の内周面に窓枠を支持する枠体を配設しているので、室内側に他の部材を配する必要がない。また、この枠体の外周の建物開口部との隙間には発泡性樹脂が充填されて発泡体が形成されているので、この発泡体により建物開口部と枠体との間での密閉性を確保することができる。
【0013】
これにより、木製サッシなどの外観美麗なサッシを用いても、その枠体の表面はそのまま屋内側に向けて露出させることが可能であり、サッシの外観をそのまま活用することができる。
【0014】
なお、上述の発明において、閉塞部材としては防水テープや壁用面材等を用いることができ、閉塞部材として防水テープを用いる場合にはこの防水テープの外面は外額縁等により化粧させることができる。
【0015】
このような建物開口部の密閉構造は、建物開口部の内周面に所定の隙間を空けて枠体を配設し、屋外側から前記隙間を閉塞部材により閉塞した後、屋内側から発泡性樹脂を注入し、該発泡性樹脂を該隙間内で発泡させて該隙間に前記発泡性樹脂の発泡体を充填させることにより製造できる。
【0016】
ここで、この閉塞部材は、防水テープ又は壁用面材であり、前記閉塞部材が防水テープである場合には、該防水テープは前記発泡性樹脂の注入前又は発泡後に外額縁等により覆い隠すことができる。
【0017】
【発明の実施の形態】
以下、本発明の具体的な実施の形態について図1〜図5を参照しつつ説明する。なお、従来技術と同一乃至は均等な部位部材は同一番号を付して説明する。
【0018】
まず、図1及び図2はそれぞれ本発明の実施の形態に係る洋高窓系の木製サッシ一枚開きの建物開口部の密閉構造10を説明する図であり、図1は、建物開口部の上縁部付近の縦断面図であり、図2は、建物開口部の一側縁部付近の平断面図である。
【0019】
まず、図1において、外壁を構成する壁面材11、石膏ボードなどの内装材12及び角材13などから構成される建物壁体14には建物開口部15が形成されている。この建物開口部15には、合板製のスペーサ16…などを介して洋高窓用の窓枠18を支持する上枠体19がそれぞれ皿木ねじ21…により固定されている。ここで、符号19aで示される上枠体19の屋内B側の表面は、内装材12の表面12aと略面一である。
【0020】
また、図2において、外壁を構成する壁面材11、石膏ボードなどの内装材12及び角材13などから構成される建物壁体14には建物開口部15が形成されている。この建物開口部15には、合板製のスペーサ16…などを介して洋高窓用の窓枠18を支持する縦枠体20が皿木ねじ21…により固定されている。ここで、符号20aで示される縦枠体20の屋内B側の表面は、内装材12の表面12aと略面一である。
【0021】
また、上枠体19の屋外A側には、図1に示すように、防水テープ22…を介在させて外額縁上枠23が皿木ねじ24により固定され、また、図2に示すように、縦枠体20の屋外A側には、防水テープ22…を介在させて外額縁縦枠25が皿木ねじ24により固定されている。
【0022】
ここで、スペーサ16…は、建物壁体14の開口面に沿って点在(図3参照)しており、各スペーサ16とスペーサ16との間には、スペーサ16の厚みに相当する厚みdの隙間17が形成され、その隙間17には発泡性樹脂が発泡された発泡体5が充填されて建物開口部の密閉構造10が形成されている。また、図中符号30はペアガラス窓を示し、符号31は、ペアガラス窓30を開閉するための把手である。
【0023】
次にこのような建物開口部の密閉構造10の作用について説明する。
【0024】
このような建物開口部の密閉構造10によれば、建物開口部15の内周面に内装材12と略面一にして窓枠18を支持する枠体19,20を配設しているので、室内側に他の部材が配されずに、木製のサッシ枠の表面がそのまま室内に向けて露出して配設できるように構成されている。
【0025】
また、この枠体19,20の外周面と建物開口部15とで形成された隙間17には発泡体5が充填され、この発泡体5は発泡性樹脂が充填されて発泡体とされたものであるので、この発泡体5により建物開口部15と枠体19,20との間での密閉性を確保することができる。
【0026】
これにより、木製サッシなどの外観美麗なサッシを用いても、その枠体の表面はそのまま屋内B側に向けて露出させることが可能であり、サッシの外観をそのまま活用することができる。
【0027】
次にこのような建物開口部の密閉構造10の製造方法の一例について説明する。
【0028】
このような密閉構造10は、建物開口部15の内周面15aに複数のスペーサ16…を介して枠体(上枠体19及び縦枠体20,20)を配設して皿木ねじ21などの固定手段により固定する。
【0029】
これにより形成された枠体19,20,20及び建物開口部15の間の隙間17の屋外A側を、図4に示すように、屋外A側から防水テープ22を貼付することにより閉塞する。これにより、隙間17の屋外A側は閉鎖されて、この隙間17は屋内B側のみに開口を有する。この隙間17は、図3において斜線で示すように、ウレタンなどの発泡性樹脂が注入される注入範囲とされる。
【0030】
ついで、図5に示すように、この隙間17に屋内B側よりウレタンなどの発泡性樹脂5´を吐出ガン26を用いて注入する。発泡性樹脂5´は隙間17内で発泡して隙間17は発泡体5により完全に充填される。
【0031】
余剰の発泡体5が表面12a、19a、20aより屋内B側に突出されるが、余剰の発泡体5は適宜カッターナイフなどにより切削可能であり、切削除去後に内装材12に跨って不図示の壁紙などの内装仕上げ材が貼付される。
屋外A側に位置する防水テープ22は発泡性樹脂5´の注入前又は発泡後に外額縁上枠23及び外額縁縦枠25によりそれぞれ屋外A側から化粧することにより覆い隠される。
【0032】
【変形例】
つぎに、変形例について図6及び図7を用いて説明するが、発明の実施の形態1と同一乃至は均等な部位部材は同一番号を付して説明する。
【0033】
まず、図6及び図7はそれぞれ本発明の変形例に係る洋高窓系の木製サッシ一枚開きの建物開口部の密閉構造10を説明する図であり、図6は、建物開口部の上縁部付近の縦断面図であり、図7は、建物開口部の一側縁部付近の平断面図である。
【0034】
これらの図において、枠体19,20,20及び建物開口部15の間の隙間17の屋外A側は、発明の実施の形態の防水テープ22に換えて、壁面材11と同一又は異なってもよい外壁の一部を構成する壁面材(壁用面材)11aにより閉塞され、この壁面材11aは、外額縁上枠23及び外額縁縦枠25により皿木ねじ24により固定されている。
【0035】
また、これらの壁面材11、11aの外側にタイル外壁11bが固定されて外壁が構成されている。タイル外壁11bと外額縁上枠23及び外額縁縦枠25との間には、弾性シーリング材27を介在させて雨水の浸入が防止されている。
【0036】
このように防水テープ22に換えて壁用面材11aにより隙間の屋外A側を閉鎖させても発明の実施の形態と略同一の作用効果を奏することができる。
【0037】
以上、本発明の実施の形態を図面により詳述したが、本発明の具体的な構成はこの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。
【0038】
例えば、以上の発明の実施の形態では、建物の窓枠について説明したが、戸枠であっても同様の作用効果を奏することができる。
【0039】
【発明の効果】
以上説明してきたように、本発明によれば、外観美麗なサッシなどにも適用できる建物開口部の密閉構造及びその製造方法を提供することができる、という実用上有益な効果を発揮する。
