Description

【０００１】
【発明の属する技術分野】
本発明は採光用天窓を構成するための合成樹脂製馳式折版屋根材と、その接続構造にに関するものである。
【０００２】
【従来の技術】
従来から、折版屋根に採光を行うための天窓部分を設ける場合、該天窓部分に採光性を有する透明又は半透明のポリカーボネート製の折版屋根材を取付けることが行われている。この場合、谷部の側端部に形成している山部同士が密接状態で重合可能な折版屋根材においては、その重合部の天壁面間をボルトによって一体的に結合しているが、このような接続構造ではボルト孔から雨水が浸入する虞れがあるばかりでなく、ボルトが腐食して長期の使用に供することができないという問題点がある。
【０００３】
このため、図16に示すように、谷部41の上端縁に外側方に向かって水平に屈曲した一定幅の山部42、43を形成していると共に、一方の山部42の突出端に上方に向かって屈曲した起立片44とこの起立片44の上端に下向きに開口46した断面Ｃ字状の屈曲縁部45を形成し、他方の山部43の水平突出端に上方に屈曲した一定高さの起立片47とこの起立片47に水平屈折部48を形成してなるポリカーボネート製折版屋根材40が開発されている。
【０００４】
そして、これらの折版屋根材40、40同士を接続するには、図17に示すように、吊子31の上端屈曲部32に一方の折版屋根材40の屈曲縁部45を被嵌させると共に他方の馳式折版屋根材40の起立片47における上端水平屈折部48を吊子31の上端屈曲部32の下面に当接させた状態にして、下向き開口の断面Ｃ字状金属製キャップ51を被せ、手動馳折り装置又は自走馳折り装置を用いて該金属製キャップ51を圧締めすることにより接続されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、金属製キャップ51を圧締めしても、吊子31に対する一方の折版屋根材40の屈曲縁部45や他方の折版屋根材40の水平屈折部48を吊子31の全長に亘って均一な圧接力でもって圧着させることは困難であり、ある部分においては隙間が生じることになる。そのため、風雨による下方からの吹き上げが生じると、雨水等が他方の折版屋根材40の起立片47の外面を伝って金属製キャップ51内に押し上げられ、吊子31の水平に屈折した上端屈曲部32と同じく水平に屈折した他方の馳式折版屋根材40の上記水平屈折部48との間の隙間を通じて屋根内に浸入し、漏水が生じるという問題点があった。
【０００６】
また、手動馳折り装置又は自走馳折り装置によって圧締めした時に、ポリカーボネート製馳式折版屋根材の屈曲縁部45が吊子31の先端で、接触部分を支点として内側方に冷間状態で屈曲変形させられるために、この屈曲部分に集中荷重による大きな残留内部応力の発生によりクラック等が生じて長期間の使用に耐えられなくなる虞れがあり、その上、金属製キャップ51と馳式折版屋根材40の屈曲縁部45とを一体的に圧締めするものであるから、従来の馳折り装置では能力不足となって精度のよい確実な圧締加工が行えない場合が生じるという問題点があった。
【０００７】
本発明はこのような問題点に鑑みてなされたもので、その目的とするところは雨水等の浸入を確実に防止し得ると共に内部に集中的な残留応力を生じさせることなく互いの接続を可能にし得る合成樹脂製の馳式折版屋根材とその接続構造を提供するにある。
【０００８】
【発明が解決しようとする課題】
上記目的を達成するために、本発明の合成樹脂製馳式折版屋根材は、請求項１に記載したように、谷部の両側端に一定幅の山部を設けていると共にこれらの山部の側端縁に上方に向かって屈曲してなる起立片をそれぞれ形成し、且つ一方の起立片の上端に大形屈折片部を、他方の起立片の上端に該大形屈折片部の下方に内包される大きさの小形屈折片部を形成してなる合成樹脂製馳式折版屋根材において、上記大形屈折片部はその先端部を下方に屈曲させることなく水平状部に形成され、上記小形屈折片部はその上端部を吊子の上端屈曲部の下面に沿う水平状部とこの水平状部の先端から下方に屈折し、金属製キャップにより被覆される止水端部とに形成されている構造としている。
【０００９】
上記合成樹脂製馳式折版屋根材において、請求項２に係る発明は、上記大形屈折片部の形状を、馳加工を施すことなく吊子の外周面に外接するように外向きに開口した多角形状屈折片部に形成していることを特徴としている。
【００１０】
また、請求項３に係る発明は上記馳式折版屋根材同士の接続構造であって、谷部の両側端に一定幅の山部を設けていると共にこれらの山部の側端縁に上方に向かって屈曲してなる起立片をそれぞれ形成し、且つ一方の起立片の上端に大形屈折片部を、他方の起立片の上端に上端部を吊子の上端屈曲部の下面に沿う水平状部とこの水平状部の先端から下方に屈折した止水端部とに形成している小形屈折片部をそれぞれ設けてなる合成樹脂製馳式折版屋根材同士の接続構造であって、一方の馳式折版屋根材の小形屈折片部の上記水平状部を吊子の上端屈曲部の下面に沿わせると共に他方の馳式折版屋根材の大形屈折片部を上記吊子に被覆させてあり、さらに、下向き開口の金属製キャップの一半部を上記大形屈折片部の外面に被覆させる一方、該金属製キャップの他半部を上記大形屈折片部の先端を変形させることなく大形屈折片部と吊子との先端部及び小形屈折片部の下方に屈折した先端止水端部を内包した状態に圧締してなることを特徴としている。
【００１１】
この馳式折版屋根材同士の接続構造において、請求項４に係る発明は請求項２に記載した発明と同じく、上記大形屈折片部の形状を、馳加工を施すことなく吊子の外周面に外接するように外向きに開口した多角形状屈折片部に形成した構造としている。
【００１２】
【作用】
風雨による下方からの吹き上げが生じた場合、雨水等が金属製キャップの先端部と馳式折版屋根材における小形屈折片部を有する起立片との間の隙間を通じて金属製キャップ内に浸入するが、雨水が小形屈折片部の水平状部の下面を伝った時に、この水平状部の先端から下方に屈折している止水端部に流突し、再び、金属製キャップと起立片との隙間側に押し戻されることになる。従って、雨水が吊子の上端屈曲部の下面と小形屈折片部の水平状部の上面との接合部にまで達することはなく、そのため、この接合部を通じての屋根内への雨水の浸入による漏水が確実に防止することができる。
【００１３】
また、合成樹脂製馳式折版屋根材は、その一方の山部の端縁における起立片の上端に形成した大形屈折片部の先端部を水平状部とし、この水平状部を屈曲させることなく隣接する馳式折版屋根材の他方の山部の端部における起立片の上端に形成した小形屈折片部に吊子を介して被覆してあり、さらに、下向き開口の金属製キャップの一半部を上記大形屈折片部の外面に被覆させる一方、該金属製キャップの他半部を上記大形屈折片部の先端を変形させることなく大小屈折片部と吊子との先端部を内包する方向に圧締してなるものであるから、金属製キャップのみを圧締めすることにより馳式折版屋根材同士の接続が可能となり、手動馳折り装置又は自走馳折り装置に必要以上の大きな圧締力を要求することなく簡単にして効率よく確実な接続が行えると共に金属製キャップの圧締時には大形屈折片部に局部的な集中荷重が作用することなく、従って、大きな残留応力が生じる虞れもなく、長期の使用に供することができる。
【００１４】
さらに、上記合成樹脂製馳式折版屋根において、上記大形屈折片部の形状を、馳加工を施すことなく吊子の外周面に外接するように外向きに開口した多角形状屈折片部に形成しておくことにより、採光用天窓の施工時に、この大形屈折片部を吊子の上端屈曲部に被せた場合、多角形状に屈折した各屈折片部が吊子に対して全長に亘って馴染み性良く線接触状態に内接し、雨水の浸透を確実に防止し得る水密性に優れた接続構造を構成することができる上に、大形屈折片部に馳加工を施すことなく吊子の外周面に該大形屈折片部を簡単且つ精度よく被覆させることができる。
【００１５】
【発明の実施の形態】
次に本発明の具体的な実施の形態を図面に基づいて説明する。図１は、平面縦長長方形状の透明ないしは半透明の合成樹脂製馳式折版屋根材Ａの正面図であって、その中央部を全長に亘って一定幅の谷部１に形成していると共にこの谷部１の両側縁を斜め上方に向かって屈折させることにより該谷部１の両側方に一定幅と高さを有する傾斜板部２、３に形成し、この両傾斜板部２、３の上端縁を外側方に向かって水平に屈曲させて一定幅の山部４、５を形成している。さらに、これらの山部４、５の外側端部を上方に屈折させて一定高さの垂直な起立片６、７をそれぞれ形成していると共に、一方の山部４の起立片６の上端に半円形状の面に沿うように多角形状に屈折し且つ外向きに開口した大形屈折片部８を形成していると共に他方の山部５の起立片７の上端に、後述する吊子12の上端屈曲部12a における水平先端部12b の下面に沿う水平状部9aとこの水平状部9aの先端から下方に屈折した止水端部9bとからなる小形屈折片部９を形成してなるものである。
【００１６】
なお、図１に示した１つの谷部を有する谷部の構造に代えて、例えば谷部の底板部の側縁に斜め外側方に向かって屈曲形成した傾斜板部の上端縁に形成している外側方に向かって水平に屈曲形成してなる一定幅の山部を介して二つもしくはそれ以上の谷部が連続してなる複数の谷部を有する上記形態の合成樹脂製馳式折版屋根材を必要に応じて適用してもよい。
【００１７】
上記馳式折版屋根材Ａにおいて起立片６、７の上端にそれぞれ形成している大形屈折片部８と小形屈折片部９との形状をさらに詳しく説明すると、大形屈折片部８は平たい小幅の屈折部8a〜8dを順次鈍角な角度（約130 度）でもって屈折させ且つその先端部の屈折部8dを下方に屈曲させることなく水平状の屈折部に形成してなるものであり、水平状部9aと止水端部9bとからなる上記小形屈折片部９はその幅を大形屈折片部８における上記水平先端部を形成している屈折部8dの幅に略等しく形成されている。また、上端にこの小形屈折片部９を一体に設けている起立片７の上半部は下半部に対して外側方に傾斜した傾斜部7aに形成している。
【００１８】
このように形成した馳式折版屋根材Ａは合成樹脂製屋根材としてポリカーボネート樹脂の成形品が広く使用されているであるが、ポリカーボネート樹脂以外の合成樹脂、例えば、アクリル樹脂、塩化ビニル樹脂、ポリエステル樹脂、或いはその他の共重合体樹脂、変性樹脂、ガラス繊維強化樹脂等より成形されたものであってもよい。
【００１９】
上記合成樹脂製馳式折版屋根材Ａは透明ないしは半透明であって、天窓などの採光材として使用される。例えば、図２に示すように鉄板などの金属製折版屋根材Ｂを複数列、組み合わせ接続してなる折版屋根において、その屋根の一部を切欠いて矩形状の開口部を設け、この開口部に該合成樹脂製馳式折版屋根材Ａを張設することによって採光用天窓が形成される。
【００２０】
複数枚の合成樹脂製馳式折版屋根材Ａを順次接続することにより大面積の採光用天窓を構成した場合における隣接する馳式折版屋根材Ａ、Ａ同士は次のような接続構造を有している。即ち、図３に示すように、受梁10（図２に示す）上のタイトフレーム11にその下端水平板部をボルトによって固定された吊子12の両側面に一方の馳式折版屋根材Ａの起立片６と他方の馳式折版屋根材Ａの起立片７とをそれぞれ接合状態に配すると共に、一方の起立片６の大形屈折片部８における水平屈折部8dの下面と他方の起立片７の小形屈折片部９における上記水平状部9aの上面とを吊子12の上端屈曲部12a における水平先端部12b の上下面に面接触状態でそれぞれ重ね合わせた状態で金属製キャップ13を被せることにより、吊子12の上端屈曲部12a と両馳式折版屋根材Ａ、Ａの大小形屈折片部８、９とを一体に固定している。
【００２１】
吊子12は起立片部12c と、この起立片部12c の上端に一体に形成されている円弧状に屈曲した上記上端屈曲部12a とを有し、且つこの上端屈曲部12a の先端部を上記小形屈折片部９における水平状部9aの幅に略等しい幅を有する水平先端部12b に形成してなるもので、この吊子12の長手方向に間隔を有して設けられている複数の受梁10上のそれぞれのタイトフレーム11にこの吊子12の下端水平板部をボルトによって固定されている。
【００２２】
金属製キャップ13はその幅方向の一半部13a を上記馳式折版屋根材Ａの大形屈折片部６の外面に接するように全長に亘って円弧状に湾曲させていると共に該一半部13a の上端部を上記大形屈折片部８における水平屈折部8dの上面に面接触する水平部13a'に形成してあり、この水平部13a'に連なる他半部13b を、吊子12の先端面とこの吊子12の水平先端部12b の上面に重ね合わせている馳式折版屋根材Ａの大形屈折片部８の先端面及び吊子12の水平先端部12b の下面に重ね合わせている馳式折版屋根材Ａの小形屈折片部９の先端から下方に屈折した止水端部9bとを被覆する円弧状屈曲部に形成している。さらに、この金属製キャップ13の両側下端部は、馳式折版屋根材Ａ、Ａの起立片６、７の外側面に圧接させる垂下端部13c 、13d に形成している。なお、この金属製キャップ13は、馳式折版屋根材Ａ、Ａの大小形屈折片部８、９に被せる前には、その両側垂下端部13c 、13d 間を拡開させた形状に形成してその被せ作業が容易に行えるように構成している。
【００２３】
このように形成している金属製キャップ13は、その開口端から上記吊子12の上端屈曲部12a に外接している馳式折版屋根材Ａにおける大形屈折片部８に被せてその円弧状に湾曲している一半部13a の内周面を大形屈折片部８の各屈折部8a〜8dの角部に内接させると共に該金属製キャップ13の水平部13a'の下面を先端屈折部8dの上面に面接触状態に重ね合わせ、さらに、上記円弧状に湾曲した他半部13b によって上述したように大形屈折片部８の先端面から吊子12の先端面を介して小形屈折片部９の止水端部9bを被覆したのち、手動馳折り装置又は自走馳折り装置（図示せず）を用いて金属製キャップ13の開口端をその開口幅が狭まる方向に圧締めし、一半部13a と他半部13b との垂下端部13c 、13d を吊子12の両側面に接合している馳式折版屋根材Ａ、Ａの起立片６、７にそれぞれ圧着させることにより、ボルトを使用することなく、この金属製キャップ12によって隣接する馳式折版屋根材Ａ、Ａ同士を吊子９を介して接続させた構造としている。
【００２４】
上記のように、馳式折版屋根材Ａにおける一方の起立片６の上端部に形成している大形屈折片部８は、吊子12における上記円弧状に屈曲した上端屈曲部12a に沿って多角形状に屈折させているので、この大形屈折片部８を吊子12の上端屈曲部12a に被せるだけで、馳加工を施すことなくその各屈折部8a〜8dを吊子12の上端屈曲部12a に外接させることができると共に、多角形に形成しているので、屈折部によって剛性が向上し、且つ吊子12の全長に亘って真っ直ぐに接合しやすくて被せ作業が正確且つ容易に行えるものであり、その上、各屈折部8a〜8dの角部が金属製キャップ13の円弧状に湾曲した一半部の内周面に全長に亘って線接触状態に内接して、大形屈折片部８と金属製キャップ13との間から雨水が浸入するのを確実に防止し得る水密性に優れた接続構造を構成することができる。
【００２５】
さらに、金属製キャップ13の上記円弧状に湾曲した他半部13b によって吊子12の先端面とこの吊子12の上下面に重ね合わせている馳式折版屋根材Ａ、Ａの大小形屈折片部８、９の先端面とを被覆させる際に、これらの先端面、即ち、吊子12の先端面とこの吊子12の水平先端部12b の上面に重ね合わせている馳式折版屋根材Ａの大形屈折片部８の先端面及び吊子12の水平先端部12b の下面に重ね合わせている馳式折版屋根材Ａの小形屈折片部９の先端から下方に屈折した止水端部9bの外面とに亘って一定幅を有する帯状のパッキン14を配設し、金属製キャップ13の圧締めにより該金属製キャップ13の他半部13b の内周面と大形屈折片部８の水平状部9aの先端面から小形屈折片部９の止水端部9bの外面に亘ってパッキン14を介装した一層良好な水密構造を構成している。
【００２６】
なお、金属製キャップ13は、圧締めする前の一半部13a の形状を馳式折版屋根材Ａにおける上記大形屈折片部８の外周面に接することなく該外周面に対して隙間が生じるように緩やかに湾曲させた形状としておき、圧締めすることによってその一半部13a を馳式折版屋根材Ａの大形屈折片部８の屈折部8a〜8dに内接させるように構成しておいてもよく、いずれにしても、馳式折版屋根材Ａの大形屈折片部８は吊子12の屈曲部12a の外周面に接しているので、金属製キャップ13の圧締時においても変形する虞れはなく、大形屈折片部８に応力が加わらず、従って残留歪みは残らない。
【００２７】
このように構成したので、図４に示すように、一方の馳式折版屋根材Ａの山部４上に風雨による吹き上げが生じた場合、該山部４上の雨水が金属製キャップ13の一方の垂下端部13c と起立片６との間の隙間を通じて浸入するが、該起立片６の上端部に形成している大形屈折片部８の各屈折部8a〜8dの角部が金属製キャップ13の円弧状に湾曲した一半部の内周面に全長に亘って線接触状態に内接しているので、雨水がそれ以上内部に浸入するのを一層確実に阻止されるものである。
【００２８】
また、他方の馳式折版屋根材Ａの山部５上に風雨による吹き上げが生じた場合には、該山部５上の雨水が金属製キャップ13の他方の垂下端部13d と起立片７との間の隙間を通じて浸入するが、雨水が小形屈折片部９の水平状部9aの下面を伝ってこの水平状部9aの先端から下方に屈折している止水端部9bに達した時にこの止水端部9bの内側面に沿って下方に流下し、再び、金属製キャップ13と起立片７との隙間側に押し戻されるので、雨水が吊子12の水平先端部12b の下面と小形屈折片部９の水平状部9aの上面との隙間を通じて屋根内に浸入する虞れはない。さらに、上記のように金属製キャップ13の他半部13b と、吊子12の先端面及びこの吊子12の上下面に重ね合わせている馳式折版屋根材Ａ、Ａの大小形屈折片部８、９の先端面との間にパッキン14を介在させておくことによって一層、良好な水密性を発揮させることができる。なお、このパッキン14は必ずしも設けておく必要はない。
【００２９】
次に、上記実施例においては、馳式折版屋根材Ａの小形屈折片部９を有する起立片７側において、該起立片７の上半部の傾斜部7aに形成してこの傾斜部7aと小形屈折片部９との連設部を円弧状に湾曲させながら水平方向に屈折させることにより小形屈折片部９の水平状部9aを形成しているが、図５に示すように、小形屈折片部９の水平状部9aの基端に連設する起立片７の上半部を吊子12の上端屈曲部12a の内側面に密接する円弧状湾曲面9cに形成しておいてもよい。また、小形屈折片部９における水平状部9aの先端から下方に屈折している止水端部9bの下端縁部を図６に示すように吊子12側に向かって屈折させておいてもよく、図７に示すように、水平状部9aの先端から止水端部9bを起立片７に向かって斜め下方に傾斜させておいてもよい。
【００３０】
さらに、上記いずれの実施例においても一方の起立片６の上端に形成している大形屈折片部８を多角形状に形成しているが、図８、図９に示すように、内外周面を吊子12の上端屈曲部12a の外周面と金属製キャップ13の内周面とにそれぞれ面接触する先端部が水平状部8d' に形成された半円弧状の屈曲部8a' に形成しておいてもよい。その他の構造は上記実施例と同様であるので、同一部分には同一符号を付して詳細な説明を省略する。なお、この図８、図９に示した実施例においても、小形屈折片部９における水平状部9aの先端から下方に屈折している止水端部9bの形状については上述した構成に変更してもよいことは勿論である。
【００３１】
図10は本発明の合成樹脂製馳式折版屋根材の別な構造を示すもので、上記各馳式折版屋根材Ａにおいては、起立片６、７の上端にそれぞれ連設してなる大小形屈折片部８、９を半円弧状に沿った湾曲形状、即ち、丸馳形状に形成したが、この実施例の合成樹脂製馳式折版屋根材A'においては角馳形状に形成し、その小形屈折片部9Aの先端に下方に屈折した止水端部9b’を設けた構造としているものである。
【００３２】
即ち、谷部１の両側に傾斜板部２、３を介して該傾斜板部２、３の上端部に形成した一定幅の山部４、５の側端縁に上方に向かって屈折してなる一定高さの垂直な起立片６、７を形成し、一方の起立片６の上端部を外側方に向かって直角方向に屈折させて一定幅を有する水平大形屈折片部8Aに形成していると共に、他方の起立片７の上端部を内側方に向かって直角方向に屈折させて上記水平大形屈折片部8Aよりも小幅の水平小形屈折片部9Aを形成し、この水平小形屈折片部9Aの先端部を下方に屈折させて止水端部9b' に形成してなるものである。
【００３３】
このように構成した合成樹脂製馳式折版屋根材A'、A'同士の接続構造は、図11に示すように、受梁（図示せず）上のタイトフレーム11にその下端水平板部をボルトによって固定された長尺の吊子12A を介して一方の馳式折版屋根材A'の起立片６及び大形屈折片部8Aと、他方の馳式折版屋根材A'の起立片７及び小形屈折片部9Aとを面接触状態で重ね合わせられている。
【００３４】
吊子12A はその上半部を垂直な起立片部12c に形成していると共にこの起立片部12c の上端を外側方に直角に屈折して一定幅を有する水平先端部12b に形成してあり、この吊子12A の起立片部12c の内外側面に隣接する馳式折版屋根材A'、A'の起立片６、７をそれぞれ密接させていると共に一方の馳式折版屋根材A'の水平大形屈折片部8Aの下面を吊子12A の水平先端部12b の上面に密接させ、他方の馳式折版屋根材A'の水平小形屈折片部9Aの上面を吊子12A の水平先端部12b の下面に密接状態で重ね合わせ、且つ、吊子12A の水平先端部12b の先端面と大形屈折片部8Aの先端面及び小形屈折片部9Aから下方に屈折している止水端部9b' の外側面とを面一に合わせた状態で、下向き開口の金属製キャップ13' を被嵌して該金属製キャップ13' の開口部の圧締めにより馳式折版屋根材A'、A'同士の接続構造を構成している。
【００３５】
上記金属製キャップ13' はその一半部13a'を馳式折版屋根材A'の水平大形屈折片部8Aから垂直な起立片６にかけて被覆し得る水平天壁片部121 と垂直脚片部122 とからなる断面逆Ｌ字状に形成し、他半部13b'を該一半部13a'の水平天壁片部121 の端縁から下方に向かって直角に屈曲した垂直上脚片部123 とこの垂直上脚片部123 の下端から内側方に屈折してなる下脚片部124 とからなり、上記水平天壁板部121 と垂直脚片部122 とを馳式折版屋根材A'の水平大形屈折片部8Aから垂直な起立片６に密接させると共に垂直上脚片部123 を大形屈折片部8Aの先端面から止水端部9bの外側面にかけて密接させた状態で、手動馳折り装置又は自走馳折り装置（図示せず）を用いて下脚片部124 を内側方に圧締めして馳式折版屋根材A'、A'同士を吊子12A を介して接続させた構造としている。
【００３６】
この構造によれば、合成樹脂製馳式折版屋根材A'や吊子12A 、及び金属製キャップ13' は屈曲部を有することなく角形に形成されているので、構造が簡単で精度のよい馳式折版屋根材A'を作製し得ると共に圧締め作業も容易に且つ精度良く行えるという利点を有する。また、前述の馳式折版屋根材Ａ、Ａ同士を吊子12を介して密接若しくは実質的に面接触させている場合の構造と同様に、金属製キャップ13' の圧締力は長尺である吊子12A の内外側面の馳式折版屋根材A'、A'の面を介して該吊子12A によって受け止められるので、該馳式折版屋根材A'、A'が変形することはない。
【００３７】
なお、吊子12A の水平先端部12b の先端面と大形屈折片部8Aの先端面及び小形屈折片部9Aから下方に屈折している止水端部9b' の外側面とからなる垂直な面と金属製キャップ13' の垂直上脚片部123 との間に帯状のパッキンを介装して水密構造を構成しておいてもよい。このようにパッキンを設けておくと、一方の馳式折版屋根材A'の山部４上に風雨による吹き上げが生じた場合に、該山部４上の雨水が金属製キャップ13' の下脚片部124 の下端と起立片６との間の隙間を通じて浸入しても、このパッキンによって雨水がそれ以上内部に浸入するのを一層確実に阻止することができる。
【００３８】
また、他方の馳式折版屋根材A'の山部５上に風雨による吹き上げが生じた場合には、該山部５上の雨水が金属製キャップ13' の下脚片部124 の先端と起立片７との間の隙間を通じて浸入するが、雨水が起立片７の水平小形屈折片部9Aの下面を伝ってこの水平小形屈折片部9Aの先端から下方に屈折している止水端部9b' に達した時に、この止水端部9b' の内側面に沿って下方に流下し、再び、金属製キャップ13' の下脚片部124 と起立片７との隙間側に押し戻されるので、雨水が吊子12A の水平先端部12b の下面と水平小形屈折片部9Aの上面との隙間を通じて屋根内に浸入する虞れはない。
【００３９】

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin-made folded folding roof material for constituting a daylighting skylight and a connection structure thereof.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when a skylight portion for daylighting is provided on a folded roof, a transparent or translucent polycarbonate folded roofing material having daylighting properties is attached to the skylight portion. In this case, in the folded roofing material that can be polymerized in close contact with the peaks formed on the side end of the valley, the top wall of the overlapped portion is integrally coupled with the bolt, In such a connection structure, not only is there a possibility that rainwater may enter from the bolt hole, but there is a problem that the bolt is corroded and cannot be used for a long time.
[0003]
Therefore, as shown in FIG. 16, ridges 42 and 43 having a constant width are formed at the upper end edge of the valley 41 and are bent horizontally toward the outside, and at the protruding end of one ridge 42. An upright piece 44 bent upward and a bent edge 45 having a C-shaped cross-section with a downward opening 46 formed at the upper end of the upright piece 44 and bent upward at the horizontal protruding end of the other peak 43 There has been developed a folded plate roof material 40 made of polycarbonate in which a standing piece 47 having a height and a horizontal refracting portion 48 are formed on the standing piece 47.
[0004]
And in order to connect these folding roof materials 40 and 40, as shown in FIG. 17, the bending edge 45 of one folding roof material 40 is fitted to the upper end bending portion 32 of the hanging element 31. In addition, the upper end horizontal refracting portion 48 of the upright piece 47 of the other saddle type folded roofing material 40 is brought into contact with the lower surface of the upper end bent portion 32 of the hanging element 31 so that the C-shaped metal cap with a downward opening is formed. 51, and the metal cap 51 is clamped using a manual folding device or a self-propelled folding device.
[0005]
[Problems to be solved by the invention]
However, even if the metal cap 51 is clamped, the bent edge 45 of one folded roofing material 40 with respect to the hanging element 31 and the horizontal refracting part 48 of the other folded roofing material 40 extend over the entire length of the hanging element 31. Therefore, it is difficult to press-fit with a uniform pressure contact force, and a gap is generated in a certain portion. Therefore, when blowing up from below due to wind and rain occurs, rainwater etc. is pushed up into the metal cap 51 along the outer surface of the upright piece 47 of the other folding roof material 40, and the upper end of the slant 31 is bent horizontally. Like the portion 32, there was a problem that water leaked by entering the roof through the gap between the horizontal folding portion 48 of the other vertical folding roof material 40 that was refracted horizontally.
[0006]
In addition, when crimped by a manual folding device or a self-propelled folding device, the bent edge 45 of the polycarbonate folding plate roof material is the tip of the hanger 31 and is in a cold state inward with the contact portion as a fulcrum. In this bending part, there is a possibility that a crack or the like may occur due to the generation of a large residual internal stress due to concentrated load in this bent part, and it may not be able to withstand long-term use. Since the bent edge portion 45 of the folded plate roofing material 40 is integrally clamped, there is a problem that the conventional scissor folding device is insufficient in capacity and may not perform accurate and reliable pressing. There was a point.
[0007]
The present invention has been made in view of such problems, and the object of the present invention is to reliably prevent intrusion of rainwater and the like, and to allow mutual connection without causing concentrated residual stress inside. The present invention provides a saddle type folding roof material made of synthetic resin and its connection structure.
[0008]
[Problems to be solved by the invention]
In order to achieve the above object, the synthetic resin crease type folded roofing material of the present invention, as described in claim 1, is provided with ridges having a constant width on both side ends of the valley, and these ridges. Standing pieces that are bent upward are formed on the side edge of each part, and the large refracting piece part is formed at the upper end of one standing piece, and the large refracting piece part is formed at the upper end of the other standing piece. In the synthetic resin crease type folded roofing material formed by forming a small refracting piece having a size included below, the large refracting piece is formed in a horizontal part without bending the tip part downward. The small refracting piece is bent at the upper end along the lower surface of the bent upper end of the suspension and downward from the tip of the horizontal portion. And covered with a metal cap Formed at the still water end Is It has a structure.
[0009]
In the above-mentioned synthetic resin crease type folded roofing material, the invention according to claim 2 is characterized in that the shape of the large refracting piece portion is opened outward so as to circumscribe the outer peripheral surface of the hanging member without subjecting to heel processing. It is characterized in that it is formed on the polygonal refraction piece.
[0010]
Further, the invention according to claim 3 is a connection structure between the above-mentioned saddle-type folded roofing materials, and is provided with crests having a constant width on both side ends of the troughs and above the side edges of these crests. And a large refracting piece at the upper end of one standing piece, the upper end at the upper end of the other standing piece, and a horizontal surface along the lower surface of the upper bent portion of the hanging piece. And a connecting structure between the synthetic resin saddle-type folded roofing materials, each of which is provided with a small refracting piece part formed on the water-proof end part refracted downward from the tip of the horizontal part, The horizontal part of the small refracting piece part of one saddle type folded roofing material is placed along the lower surface of the upper bent portion of the hanging element and the large refracting piece part of the other folding type roofing material is used as the hanging part. A metal cap having a downward opening is coated on the outer surface of the large refractive piece, The other half of the cap made of the genus includes the distal end of the large refractive piece and the tip of the large refracting piece without changing the tip of the large refracting piece and the water-stop end that is refracted below the small refracting piece. It is characterized by being pressed into a pressed state.
[0011]
In the connection structure between the saddle-type folded roof materials, the invention according to claim 4 is the same as the invention described in claim 2, and the shape of the large refracting piece portion is the outer periphery of the hanger without subjecting it to scissoring. The structure is formed in a polygonal refraction piece that opens outward so as to circumscribe the surface.
[0012]
[Action]
When blowing up from below due to wind and rain, rainwater or the like enters the metal cap through the gap between the tip of the metal cap and the standing piece having a small refracting piece in the saddle-type folded roofing material. When rainwater travels along the lower surface of the horizontal portion of the small refracting piece, it spills from the tip of the horizontal portion to the water-stopping end that refracts downward, and again, the metal cap and the standing piece It will be pushed back to the gap side. Therefore, rainwater does not reach the joint between the lower surface of the upper bent portion of the suspension and the upper surface of the horizontal portion of the small refracting piece, and therefore leakage due to the intrusion of rainwater into the roof through this joint. Can be reliably prevented.
[0013]
Further, the synthetic resin saddle-type folded roofing material has a horizontal portion as a tip of a large refracting piece formed at the upper end of the upright piece at the edge of one of the peaks, and the horizontal portion is bent. Without covering the small refracting piece formed at the upper end of the upright piece at the end of the other peak part of the adjacent ridge-type folded roofing material without hanging, further, the metal cap of the downward opening One half is covered on the outer surface of the large refracting piece, while the other half of the metal cap is attached to the tip of the large and small refracting piece without hanging the tip of the large refracting piece. Because it is pressed in the direction of inclusion, it is possible to connect the saddle type folding roof materials by pressing only the metal cap, and it is more than necessary for manual folding or self-propelled folding machines. Easy, efficient and secure connection without requiring a large clamping force Without acts locally concentrated load to large refractive piece portion during clamping of the metal cap with enable, therefore, no possibility that large residual stress is generated, can be subjected to long-term use.
[0014]
Furthermore, in the above-mentioned synthetic resin saddle type folded roof, the shape of the large refracting piece part is changed to a polygonal refracting piece part that opens outward so as to circumscribe the outer peripheral surface of the hanging member without subjecting the hooking process. By forming this, when constructing the daylighting skylight, when this large refracting piece part is put on the upper bent part of the hanging part, each refracting piece part refracted in a polygonal shape covers the entire length with respect to the hanging part. It is possible to form a connection structure with excellent water tightness that can be inscribed in a line contact state with good adaptability and reliably prevent the infiltration of rainwater. The large refracting piece can be easily and accurately covered on the outer peripheral surface of the lens.
[0015]

However, synthetic resins other than polycarbonate resin, such as acrylic resin, vinyl chloride resin, It may be molded from a polyester resin, other copolymer resin, modified resin, glass fiber reinforced resin, or the like.
[0019]
The synthetic resin folding folding roof material A is transparent or translucent and is used as a lighting material such as a skylight. For example, as shown in FIG. 2, in a folded roof made by combining and connecting a plurality of metal folded roof materials B such as iron plates, a part of the roof is cut out to provide a rectangular opening, and this opening A daylighting skylight is formed by stretching the synthetic resin crease type folded roofing material A on the part.
[0020]
Adjacent saddle type folding roof materials A and A in the case where a large area lighting skylight is constructed by sequentially connecting a plurality of synthetic resin saddle type folding roof materials A have the following connection structure: Have. That is, as shown in FIG. 3, one saddle-type folded roofing material is provided on both sides of a suspension 12 in which a horizontal plate at its lower end is fixed to a tight frame 11 on a receiving beam 10 (shown in FIG. 2) by bolts. A standing piece 6 of A and the standing piece 7 of the other vertical folding roof material A are arranged in a joined state, and the lower surface of the horizontal refracting portion 8d and the other of the large refracting piece portion 8 of the one standing piece 6 The metal cap in a state where the upper surface of the horizontal portion 9a of the small refracting piece portion 9 of the upright piece 7 and the upper and lower surfaces of the horizontal tip portion 12b of the upper end bent portion 12a of the suspension 12 are superposed in a surface contact state. 13, the upper end bent portion 12a of the suspension 12 and the large and small refracting pieces 8 and 9 of the double-folded folding roof materials A and A are fixed integrally.
[0021]
The hanger 12 has an upright piece 12c and the upper end bent portion 12a bent in an arc shape formed integrally with the upper end of the upright piece 12c, and the tip of the upper end bent portion 12a is connected to the end portion of the upright piece 12a. The small refracting piece 9 is formed on a horizontal tip 12b having a width substantially equal to the width of the horizontal portion 9a. A horizontal plate portion at the lower end of the suspension 12 is fixed to each tight frame 11 on the beam 10 with a bolt.
[0022]
The metal cap 13 has a half portion 13a in the width direction curved in an arc shape over the entire length so as to be in contact with the outer surface of the large refracting piece portion 6 of the saddle type folded roofing material A, and the half portion 13a.

The surface and the top surface of the large refractive piece 8 of the saddle-type folded roofing material A superimposed on the top surface of the horizontal tip 12b of the suspension 12 and the bottom surface of the horizontal tip 12b of the suspension 12 It is formed in the circular-arc-shaped bending part which coat | covers the water stop edge part 9b refracted | downward from the front-end | tip of the small refracting piece part 9 of the vertical folding roof material A. Further, the lower end portions on both sides of the metal cap 13 are formed on the hanging lower end portions 13c and 13d which are brought into pressure contact with the outer surfaces of the upright pieces 6 and 7 of the saddle type folded roofing material A and A, respectively. The metal cap 13 is formed in a shape in which the space between the bottom end portions 13c and 13d on both sides is widened before being covered on the large and small refracting pieces 8 and 9 of the saddle type folded roofing material A and A. Thus, the covering work can be easily performed.
[0023]
The metal cap 13 formed in this way covers the large refracting piece portion 8 of the saddle type folded roofing material A circumscribing the upper end bent portion 12a of the hanging element 12 from its open end. The inner circumferential surface of the half portion 13a that is curved in an arc is inscribed in the corners of the refractive portions 8a to 8d of the large refractive piece 8, and the lower surface of the horizontal portion 13a 'of the metal cap 13 is bent at the tip. In addition to the upper surface of the portion 8d in a surface contact state, the small half refraction from the distal end surface of the large refracting piece portion 8 through the distal end surface of the hanger 12 as described above by the other half portion 13b curved in the arc shape. After covering the water-stop end 9b of the piece 9, the open end of the metal cap 13 is pressed in a direction in which the opening width is narrowed by using a manual folding device or a self-propelled folding device (not shown). Standing of vertical folding roofing materials A and A in which hanging ends 13c and 13d of one half 13a and the other half 13b are joined to both side surfaces of the suspension 12 By crimping each of the pieces 6 and 7, the saddle type folded roofing materials A and A are connected to each other via a hanging member 9 by the metal cap 12 without using a bolt.
[0024]
As described above, the large refracting piece portion 8 formed at the upper end portion of one upright piece 6 of the saddle type folded roofing material A is along the upper end bent portion 12a bent in the arc shape in the hanging element 12. Since the large refracting piece 8 is simply put on the upper bent portion 12a of the hanger 12, each of the refracting portions 8a to 8d can be applied to the upper end of the hanger 12 without any wrinkling. Since it can be circumscribed to the bent portion 12a and is formed in a polygonal shape, rigidity is improved by the refracting portion, and it is easy to join straightly over the entire length of the suspension 12, so that the covering work is accurate and easy. In addition, the corners of each of the refracting parts 8a to 8d are inscribed in a line contact state over the entire length of the inner circumferential surface of one half of the metal cap 13 that is curved in an arc shape, and large refraction. Excellent water tightness that can reliably prevent rainwater from entering between the piece 8 and the metal cap 13 It is possible to configure a connection structure.
[0025]
Further, the large and small refraction of the saddle type folding roof materials A and A superimposed on the front end surface of the hanging element 12 and the upper and lower surfaces of the hanging element 12 by the other half portion 13b of the metal cap 13 curved in the arc shape. When covering the tip surfaces of the pieces 8 and 9, the saddle-type folded roof that overlaps these tip surfaces, that is, the tip surface of the hanger 12 and the upper surface of the horizontal tip portion 12 b of the hanger 12. Water stop refracted downward from the tip of the small refracting piece 9 of the saddle-type folded roofing material A superimposed on the tip surface of the large refracting piece 8 of the material A and the lower surface of the horizontal tip 12b of the hanger 12. A band-shaped packing 14 having a constant width is arranged over the outer surface of the end portion 9b, and the inner peripheral surface of the other half portion 13b of the metal cap 13 and a large refracting piece portion are pressed by the metal cap 13. 8 has a better watertight structure with a packing 14 extending from the front end surface of the horizontal portion 9a to the outer surface of the water stop end portion 9b of the small refractive piece 9. There.
[0026]
The metal cap 13 has a gap with respect to the outer peripheral surface thereof without contacting the outer peripheral surface of the large refracting piece portion 8 of the saddle type folded roofing material A with the shape of the half portion 13a before being pressed. The one half portion 13a is inscribed in the refracting portions 8a to 8d of the large refracting piece portion 8 of the saddle type folded roofing material A by press-tightening. In any case, the large refracting piece 8 of the saddle-type folded roofing material A is in contact with the outer peripheral surface of the bent portion 12a of the hanger 12, so that when the metal cap 13 is pressed There is no risk of deformation, and no stress is applied to the large refracting piece 8, and therefore no residual strain remains.
[0027]
With this configuration, as shown in FIG. 4, when blowing up due to wind and rain occurs on the mountain portion 4 of one saddle type folded roofing material A, rainwater on the mountain portion 4 is transferred to the metal cap 13. It penetrates through a gap between one hanging lower end portion 13c and the upright piece 6, but the corners of the respective refractive portions 8a to 8d of the large refractive piece portion 8 formed at the upper end portion of the upright piece 6 are metal. Since the inner circumferential surface of the half of the cap 13 that is curved in the shape of an arc is inscribed in a line contact state over the entire length, rainwater can be more reliably prevented from entering the interior.
[0028]
Further, when blowing up due to wind and rain occurs on the mountain portion 5 of the other saddle type folding roof material A, the rain water on the mountain portion 5 is caused by the other drooping lower end portion 13d of the metal cap 13 and the upright piece 7. When the rainwater reaches the water stop end 9b that is refracted downward from the tip of the horizontal portion 9a through the lower surface of the horizontal portion 9a of the small refractive piece 9 Since the water flows downward along the inner surface of the water stop end 9b and is pushed back again to the gap between the metal cap 13 and the upright piece 7, the rainwater has a small size and a lower surface of the horizontal front end 12b of the hanger 12. There is no possibility of entering the roof through a gap with the upper surface of the horizontal portion 9a of the refracting piece portion 9. Further, as described above, the large and small refracting pieces of the saddle type folded roofing materials A and A superimposed on the other half portion 13b of the metal cap 13, the tip surface of the hanging element 12, and the upper and lower surfaces of the hanging element 12. By providing the packing 14 between the tip surfaces of the portions 8 and 9, better water tightness can be exhibited. Note that the packing 14 is not necessarily provided.
[0029]
Next, in the above-mentioned embodiment, on the upright piece 7 side of the saddle type folded roofing material A having the small refracting piece 9, it is formed on the inclined portion 7 a of the upper half of the upright piece 7 and this inclined portion 7 a. The horizontal portion 9a of the small refracting piece 9 is formed by bending the connecting portion of the small refracting piece 9 in a horizontal direction while curving in a circular arc shape. However, as shown in FIG. Even if the upper half of the upright piece 7 connected to the base end of the horizontal portion 9a of the refracting piece portion 9 is formed on an arcuate curved surface 9c that is in close contact with the inner surface of the upper end bent portion 12a of the hanger 12. Good. Further, the lower end edge portion of the water stop end portion 9b refracting downward from the front end of the horizontal portion 9a in the small refracting piece portion 9 may be refracted toward the hanger 12 as shown in FIG. Alternatively, as shown in FIG. 7, the water stop end portion 9 b may be inclined obliquely downward from the tip of the horizontal portion 9 a toward the upright piece 7.
[0030]
