【発明の属する技術分野】
本発明は、アーチ（ボールト）型等を含めた軒棟方向の縦葺屋根を形成するために野地板等の屋根下地に横方向（軒棟方向と直交する方向）に接続されて葺かれる縦葺屋根材の接続構造に関するものである。
【０００２】
【従来の技術】
従来より、図８（ａ）（ｂ）に示すような縦葺屋根材Ａ′が提案されている。縦葺屋根材Ａ′は、略平板状の屋根材本体１の一方の側端部（屋根下地の傾斜方向と平行な端部で例えば軒棟方向と平行な端部）の略全長に亘って嵌合部２を上方（縦葺屋根材Ａ′の表面側）に向けて突出させると共に屋根材本体１の他方の側端部の略全長に亘って被嵌合部３を上方に向けて突出させることによって形成されている。
【０００３】
縦葺屋根材Ａ′の一方の側端部は図８（ｂ）に示すように、上方に凸の略円弧状で屋根材本体１の側端部に外方（屋根材本体１と反対方向）斜め上方に突出させて連設される円弧片５５と、円弧片５５の先端から上方に略垂直に突出させて形成される突出片５６と、突出片５６の先端から外方に略水平に突出させて断面略倒Ｕ字状に屈曲形成される突部５８と、突部５８の端部から上方に突出させて断面略逆Ｕ字状に折り曲げて形成される嵌合部２と、嵌合部２の先端（外側下端）から内方（屋根材本体１側）に向けて略水平に突出させて断面略倒Ｕ字状に形成される当接部５９とから構成されており、突部５８と当接部５９は互いにほぼ対向させて形成されている。
【０００４】
また、縦葺屋根材Ａ′の他方の側端部は図８（ｂ）に示すように、上方に凸の略円弧状で屋根材本体１の側端部に外方斜め上方に突出させて連設される円弧片６０と、円弧片６０の先端から上方に略垂直に突出させて形成される突出片６１と、突出片６１の先端から外方に略水平に突出させて形成される被受け部６２と、被受け部６２の先端を上方に向けて断面略逆Ｖ字状に突出させて設けられた被嵌合部３とから構成されている。
【０００５】
図９（ａ）（ｂ）には上記の縦葺屋根材Ａ′を屋根下地４に固定するための吊子Ｂ′が示されている。この縦葺屋根材用の吊子Ｂ′は、平板状の固定部６９と、固定部６９の一側端部から上方に略垂直に突出させて形成される立ち上がり部７０と、立ち上がり部７０の上端から固定部６９と反対方向で斜め下方に突出させて形成される挟持部７１と、立ち上がり部７０の固定部６９側の面から固定部６９の上面に亘って突出して形成されている左右一対のリブ部７３と、一対のリブ部７３の間において立ち上がり部７０の固定部６９と反対側の面に突設される受け部７２とから構成されている。上記の各リブ部７３には、両側方に開口する凹部７４がそれぞれ凹設してあって、この凹部７４の上側縁部が段部７７となっている。さらに上記の立ち上がり部７０と挟持部７１とで断面略逆Ｖ字状で溝状の係合部７５が形成されており、係合部７５の下側（内側）において受け部７２が形成されている。
【０００６】
そして、上記の縦葺屋根材Ａ′を葺設するにあたっては次のようにして行う。まず、吊子Ｂ′の係合部７５を縦葺屋根材Ａ′の被嵌合部３に上側から嵌め込んで圧接させて係合させると共に縦葺屋根材Ａ′の被受け部６２を吊子Ｂ′の受け部７２に載置させて被嵌合部３の外側下端部を弾性的に係止させることによって、縦葺屋根材Ａ′の被嵌合部３の所定箇所に複数個の吊子Ｂ′を取り付ける。次に、屋根勾配と嵌合部２及び被嵌合部３が略平行となるようにして野地板等の屋根下地４に縦葺屋根材Ａ′を載置する。次に、縦葺屋根材Ａ′に取り付けられた各吊子Ｂ′の固定部６９の通孔６３を通して釘やビスなどを屋根下地４に固定することによって、複数個の吊子Ｂ′を介して上記の縦葺屋根材Ａ′を屋根下地４に取り付ける。
【０００７】
次に、屋根下地４に固定された上記縦葺屋根材Ａ′にこれとは別の他の縦葺屋根材Ａ′を接続する。屋根下地４に固定された縦葺屋根材Ａ′に他の縦葺屋根材Ａ′を接続するにあたっては、屋根下地４に固定されている縦葺屋根材Ａ′の被嵌合部３に上方から他の縦葺屋根材Ａ′の嵌合部２を嵌め込み、次に嵌合部２に上側から手で押さえたり足で踏んだりして力を加える。このように上側の縦葺屋根材Ａ′の嵌合部２に上側から力を加えることによって、上側の縦葺屋根材Ａ′の嵌合部２が側方に弾性的に広がった状態で下方へと移動し、上側の縦葺屋根材Ａ′の突部５８が吊子Ｂ′のリブ部７３の凹部７４に達すると共にこの縦葺屋根材Ａ′の当接部５９が吊子Ｂ′の挟持部７１の下方に達すると、嵌合部２が復元力（スプリングバック）によって広がった状態から元の形状に戻り、上側の縦葺屋根材Ａ′の突部５８の先端が吊子Ｂ′のリブ部７３の凹部７４に入り込んで凹部７４の底面に当接すると共にこの縦葺屋根材Ａ′の当接部５９が吊子Ｂ′の挟持部７１と屋根下地４に固定されている下側の縦葺屋根材Ａ′の被受け部６２との間に差し込まれる。このようにして上側に配置される縦葺屋根材Ａ′の嵌合部２の下側に、屋根下地４の上に固定された下側の縦葺屋根材Ａ′の被嵌合部３とこれに嵌着された吊子Ｂ′の上部を嵌合することによって、図１０に示すように隣接する縦葺屋根材Ａ′、Ａ′同士を接続することができる。この後、上記一連の作業を繰り返し行うことによって、複数枚の縦葺屋根材Ａ′を屋根下地４の上に葺設することによって屋根が形成されるのである。
【０００８】
上記のような縦葺屋根材Ａ′にあって、接続部分の防水性（水密性）はその外側を囲うように配置される嵌合部２による一次防水と、突部５８及び被受け部６２と屋根下地４の間に形成される内部の減圧空間（エアポケット）８０による二次防水とで確保している。この場合、通常の風雨に対しては充分な防水性を発揮する。しかし、緩勾配で且つ軒棟方向に長い屋根下地４に葺設された場合、あるいは積雪地で起こるすが漏れ（軒先部にできる氷提）の場合などでは、接続部分の高さを越えた雨水が溜まって接続部分に大量の水が進入する可能性があり、屋根の防水性を確保することが困難になることがあった。
【０００９】
そこで、図１１に示すような帯状のシール材１０で防水性を向上させることが行われている。このシール材１０はゴムなどの弾性体で形成されるものであって、被受け部６２の上側において被嵌合部３の基部（の側面）に全長に亘って貼り付けられるものであり、上記のように嵌合部２と被嵌合部３を嵌合することにより、図１２に示すように嵌合部２の当接部５９の先端がシール材１０に密着することになって、防水性を向上させようとしたものである。
【００１０】
【発明が解決しようとする課題】
しかし、縦葺屋根材Ａ′の成型時及び成型後において上記のような被嵌合部３の基部にシール材１０を貼り付けることは非常に難しいものであった。すなわち、被嵌合部３の基部にシール材１０を貼り付けようとすると、被嵌合部３の先端（外側下端）と被受け部６２の間の狭い隙間にシール材１０を挿入しなければならず、また、被嵌合部３の先端が刃物の如く飛び出した形状であって危険であり、さらに、被嵌合部３の基部は上方から見えにくい位置にあり、このような理由からシール材１０を貼り付けることは非常に難しく、且つ時間のかかる作業であった。特に、縦葺屋根材Ａ′を屋根下地４の上に揚げた後では高所における作業になってさらに貼り付け作業が困難になるものであった。
【００１１】
本発明は上記の点に鑑みてなされたものであり、屋根の防水性を向上させることができ、また、シール材の取り付けを容易に行うことができて作業性を向上させることができ、さらに、外観を損なわないようにすることができる縦葺屋根材の接続構造を提供することを目的とするものである。
【００１２】
【課題を解決するための手段】
本発明の請求項１に係る縦葺屋根材の接続構造は、一方の側端部に断面略逆Ｕ字状の嵌合部２を設けると共に他方の側端部に被嵌合部３を設けて縦葺屋根材Ａを形成し、固定部９に支持部４０と係止部２０とを立設して吊子Ｂを形成し、吊子Ｂを固定部９にて屋根下地４に固定すると共に吊子Ｂの係止部２０に縦葺屋根材Ａの被嵌合部３を係止し、縦葺屋根材Ａの嵌合部２の内側にシール材１０を挿着し、縦葺屋根材Ａの嵌合部２を隣接する縦葺屋根材Ａの被嵌合部３に被嵌させることにより被嵌合部３の上端部と支持部４０の上端部にシール材１０を圧接させて被嵌合部３と支持部４０の支持により嵌合部２の内面にシール材１０を密着して成ることを特徴とするものであり、シール材１０を被嵌合部３と支持部４０で支持して嵌合部２の内面に密着させることによって、隣接する縦葺屋根材Ａ同士の接続部分の防水性能を向上させることができるものである。また、シール材１０は狭い空間に挿入しないで取り付けることができ、シール材１０の取り付けを容易に行うことができて作業性を向上させることができるものである。また、シール材１０は嵌合部２の内側に収納することができ、嵌合部２の外側にはみ出ないようにして外観を損なわないようにすることができる。
【００１３】
また、本発明の請求項２に係る縦葺屋根材Ａの接続構造は、請求項１の構成に加えて、被嵌合部３に下側から当接して支持することにより、シール材１０の圧接による被嵌合部３の下側への変形を防止するための変形防止片７を吊子Ｂに設けて成ることを特徴とするものであり、シール材１０の圧接による被嵌合部３の変形を変形防止片７で防止することによって、シール材１０と被嵌合部３の密着性が低下しないようにすることができ、防水性能の低下を防止することができるものである。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１５】
縦葺屋根材Ａは耐食性のある金属板等を折り曲げ加工して形成されるものであって、例えば、カラー鋼板やカラーステンレス鋼板、又は塩化ビニル系樹脂やフッ素系樹脂をラミネートした鋼板などを用いることができる。図２（ａ）に示すように縦葺屋根材Ａは、略水平板状もしくは小波形状（同一間隔で連続的に凹と凸の繰り返し模様を有する形状）の屋根材本体１の一方の側端部（屋根下地４の傾斜方向と平行な端部で例えば軒棟方向と平行な端部）の略全長に亘って嵌合部２を上方（縦葺屋根材Ａの表面側）に向けて突出させると共に屋根材本体１の他方の側端部の略全長に亘って被嵌合部３を上方に向けて突出させることによって形成されている。
【００１６】
縦葺屋根材Ａの一方の側端部は図２（ｂ）に示すように、上方に向かって凸の略円弧状で屋根材本体１の側端部に外方（屋根材本体１と反対方向）斜め上方に突出させて連設される円弧片１５と、円弧片１５の端部から上方に突出させて形成される突出片１６と、突出片１６の端部から外方に突出させて形成される載置片１７と、載置片１７の端部から上方に突出させて形成される断面略逆Ｕ字状の突部８と、突部８の端部から上方に突出させて形成される断面略逆Ｕ字状の嵌合部２と、嵌合部２の端部から内方（屋根材本体１の方向）に突出させて形成される折り返し部１９とから構成されている。
【００１７】
また、縦葺屋根材Ａの他方の側端部は図２（ｃ）に示すように、上方に向かって凸の略円弧状で屋根材本体１の側端部に外方斜め上方に突出させて連設される円弧片３０と、円弧片３０の端部から上方に突出させて形成される突出片３１と、突出片３１の端部から外方に突出させて形成される延設片１２と、延設片１２の先端から上方に突出させて形成される被嵌合部３とから構成されている。被嵌合部３は、延設片１２の端部から上方に突出させて形成される断面略倒Ｓ字状の被係止部１８と、被係止部１８の端部から外方に突出させて形成されるシール密着片３３と、シール密着片３３の端部から下側に折り返されて形成される折り曲げ片３４から構成されている。
【００１８】
図３（ａ）乃至（ｄ）には上記の縦葺屋根材Ａを屋根下地４に固定するための吊子Ｂが示されている。この吊子Ｂは平板状の固定部９に係止部２０と一対の支持部４０とを設けて形成されている。支持部４０は固定部９の一方の側端部から上方に突出させて形成されており、その上部は断面略逆Ｕ字状に形成されている。また、固定部９と支持部４０の境界部分にはリブ部７３が突設されている。係止部２０は一対の支持部４０の間に設けられているものであって、固定部９の上記一方の側端部から固定部９と反対側且つ上方に向かって突出させて断面略Ｌ字状に形成されており、その上部は断面略Ｕ字状に形成されている。また、係止部２０の固定部９側の面と固定部９の上面までに亘ってリブ部７３が突設されている。さらに、係止部２０の両側端部には固定部９側に突出する変形防止片７が設けられている。変形防止片７の上端は略三角形状に形成されており、また、変形防止片７の上端と係止部２０の上端とは、ほぼ同じ高さに位置するように形成されている。
【００１９】
次に、上記の吊子Ｂを用いて縦葺屋根材Ａを葺設する施工例を説明する。まず、吊子Ｂの係止部２０を縦葺屋根材Ａの被嵌合部３の被係止部１８に上側から挿入（圧入）することによって、縦葺屋根材Ａの一方の側端部に沿って所定箇所に複数個の吊子Ｂを取り付ける。吊子Ｂは約６００ｍｍの間隔などの一定のピッチで取り付けるのが好ましい。一方、上記の縦葺屋根材Ａとは別の他の縦葺屋根材Ａの嵌合部２の内側（下側）には図４（ａ）に示すように、シール材（シールパッキン）１０を嵌合部２にその下側開口から差し込んで嵌合部２の全長に亘って収納する。シール材１０はゴムなどの弾性体で長尺の円筒状等に形成されるものであって、断面略Ｕ字状の嵌合部２の内側（下側）の空間と同じかあるいはやや小さい外径を有するものである。このような縦葺屋根材Ａへの吊子Ｂ及びシール材１０の取り付けは地上で行なうのが好ましく、これにより、高所における作業を少なくして危険を低減することができる。もちろん、屋根下地４の上で上記の作業を行っても良い。
【００２０】
次に、多数枚の縦葺屋根材Ａをクレーン等で野地板等の屋根下地４の上に搬送する。次に、屋根下地４の上面と嵌合部２及び被嵌合部３が略平行となるようにして縦葺屋根材Ａを載置する。次に、縦葺屋根材Ａに取り付けられた各吊子Ｂの固定部９に設けた通孔４４を通して屋根下地４に釘やビスなどの固定具４７を打入することにより吊子Ｂを屋根下地４に固定することによって、複数個の吊子Ｂを介して上記縦葺屋根材Ａを屋根下地４に取り付けて固定する。
【００２１】
次に、屋根下地４に固定された上記の縦葺屋根材Ａにこれとは別の他の縦葺屋根材Ａを接続する。屋根下地４の上に固定された縦葺屋根材Ａに他の縦葺屋根材Ａを接続するにあたっては、図４（ａ）に示すように、屋根下地４に固定されている下側の縦葺屋根材Ａの被嵌合部３に上方から他の縦葺屋根材Ａの嵌合部２を被せ、この嵌合部２に上から手で押さえたり足で踏んだりして力を加える。このように上側の他の縦葺屋根材Ａの嵌合部２を上から押圧することによって、上側の縦葺屋根材Ａの折り返し部１９の先端を下側の縦葺屋根材Ａの被嵌合部３の被係止部１８の外面に沿って下方に移動させると共に上側の縦葺屋根材Ａの突部８を吊子Ｂの支持部４０に当接させた状態で下方に移動させる。これにより、図４（ｂ）に示すように、吊子Ｂの支持部４０が固定片９と反対側に向かって傾斜するように弾性変形すると共に、押圧されている嵌合部２が横方向に弾性的に広がった状態で下方へと移動していく。そして、上側の縦葺屋根材Ａの突部８が吊子Ｂの支持部４０の断面略逆Ｕ字状の部分よりも下側に達すると共に上側の縦葺屋根材Ａの折り返し部１９が下側の縦葺屋根材Ａの被嵌合部３の被係止部１８の下側に達すると、吊子Ｂの支持部４０が固定片９側に向かって傾斜するように元の位置に戻ると共に、押圧されている嵌合部２が復元力（スプリングバック）によって広がった状態からほぼ元の形状に戻り、この結果、吊子Ｂの支持部４０に上側の縦葺屋根材Ａの突部８が弾性的に当接すると共に上側の縦葺屋根材Ａの折り返し部１９が下側の縦葺屋根材Ａの延設片１２と被係止部１８の間に挿入されて被係止部１８に弾性的に係止される。
【００２２】
また、上側の縦葺屋根材Ａの嵌合部２の内側（下側）においてシール材１０が圧縮された状態となって、上側の縦葺屋根材Ａの嵌合部２の内側面（下面）と下側の縦葺屋根材Ａの被嵌合部３のシール密着片３３の上面と被係止部１８の外面及び吊子Ｂの支持部４０の上端部とに圧接して密着することになり、嵌合部２と被嵌合部３の間にシール材１０が充填されることになる。この時、下側の縦葺屋根材Ａの被嵌合部３はシール材１０により上側から押圧されて下側に向かって変形しようとするが、被嵌合部３のシール密着片３３の下側に形成された折り曲げ片３４が変形防止片７の上端に当接して被嵌合部３が支持されるために、被嵌合部３の下側への変形が防止されるものである。
【００２３】
このようにして他の縦葺屋根材Ａの嵌合部２を屋根下地４の上に固定された縦葺屋根材Ａの被嵌合部３とこれに嵌着された吊子Ｂの上部に被嵌することによって、図１に示すように屋根下地４に固定されている縦葺屋根材Ａの被嵌合部３と他の縦葺屋根材Ａの嵌合部２を嵌合させて隣接する縦葺屋根材Ａ、Ａ同士を接続することができる。この後、上記一連の作業を繰り返し行うことによって、複数枚の縦葺屋根材Ａを屋根下地４の上に葺設することによって屋根が形成されるのである。
【００２４】
上記のように本発明の縦葺屋根材Ａの接続構造では、シール材１０を被嵌合部３と支持部４０とに圧接させて支持することにより嵌合部２の内面に密着させることができ、隣接する縦葺屋根材Ａ同士の接続部分の防水性能を向上させることができるものである。さらに、本発明ではシール材１０を減圧空間（エアポケット）８０よりも上方で接続部分の頭頂部にて止水するために雨水が溜まってもシール材１０の部分にまで雨水が到達しにくくなり、従来例の位置にシール材１０を設けるよりも格段に防水性を高めることができるものである。しかも、シール材１０で上側から押圧される被嵌合部３を変形防止片７で下側から支持して被嵌合部３の下側への変形を防止することによって、シール材１０と被嵌合部３との間に隙間が生じるのを防いでシール材１０と被嵌合部３の密着性を高く維持することができ、防水性能の低下を防止することができるものである。
【００２５】
また、シール材１０を嵌合部２の内側に収納して縦葺屋根材Ａに取り付けることによって、従来例のような狭い空間に挿入しないで取り付けることができ、シール材１０の取り付けを容易に行うことができて作業性を向上させることができるものである。加えて、従来例では貼り付けたシール材１０の位置のバラツキなどで、シール材１０が当接部５９と被受け部６２の間から外部に露出して外観を損なうことがあったが、本発明では、シール材１０の貼り付け位置が少々ずれたとしても、外部への露出は皆無であり外観を損なわないようにすることができるものであり、意匠性を向上させることができるものである。
【００２６】
図５（ａ）乃至（ｃ）には上記の縦葺屋根材Ａを屋根下地４に固定するための吊子Ｂの他例を示す。この吊子Ｂは平板状の固定部９に係止部２０と一対の支持部４０とを設けて形成されている。支持部４０は固定部９の一方の側端部から斜め上方に突出させて形成されており、その上部は断面略逆Ｕ字状に形成されている。また、支持部４０の上端には斜め上方に突出させて突片５が形成されている。この突片５は支持部４０の上部の屈曲部分の一部を切り起こすことによって形成されている。また、支持部４０の固定部９側の面には被載置部６５が突設されている。さらに、固定部９と支持部４０のリブ部７３が突設されている。係止部２０は一対の支持部４０の間に設けられているものであって、固定部９の上記一方の側端部から固定部９と反対側且つ上方に向かって突出させて断面略Ｌ字状に形成されており、その上部は断面略Ｕ字状に形成されている。また、係止部２０の折れ曲がり部分にはリブ部７３が突設されている。
【００２７】
次に、この吊子Ｂを用いて縦葺屋根材Ａを葺設する施工例を説明する。まず、吊子Ｂの係止部２０を縦葺屋根材Ａの被嵌合部３の被係止部１８に上側から挿入することによって、縦葺屋根材Ａの一方の側端部に沿って所定箇所に複数個の吊子Ｂを取り付ける。吊子Ｂは約６００ｍｍの間隔などの一定のピッチで取り付けるのが好ましい。また、吊子Ｂを縦葺屋根材Ａに上記のようにして取り付けると、吊子Ｂの突片５の先端と縦葺屋根材Ａの被嵌合部３のシール密着片３３の端部とが対向するように近接配置された状態となる。一方、上記の縦葺屋根材Ａとは別の他の縦葺屋根材Ａの嵌合部２の内側（下側）には上記と同様のシール材１０を嵌合部２の全長に亘って収納する。次に、多数枚の縦葺屋根材Ａをクレーン等で野地板等の屋根下地４の上に搬送する。次に、屋根下地４の上面と嵌合部２及び被嵌合部３が略平行となるようにして縦葺屋根材Ａを載置する。次に、縦葺屋根材Ａに取り付けられた各吊子Ｂの固定部９に設けた通孔４４を通して屋根下地４に釘やビスなどの固定具４７を打入することにより吊子Ｂを屋根下地４に固定することによって、複数個の吊子Ｂを介して上記縦葺屋根材Ａを屋根下地４に取り付けて固定する。
【００２８】
次に、屋根下地４に固定された上記の縦葺屋根材Ａにこれとは別の他の縦葺屋根材Ａを接続する。屋根下地４の上に固定された縦葺屋根材Ａに他の縦葺屋根材Ａを接続するにあたっては、屋根下地４に固定されている下側の縦葺屋根材Ａの被嵌合部３に上方から他の縦葺屋根材Ａの嵌合部２を被せ、この嵌合部２に上から手で押さえたり足で踏んだりして力を加える。このように上側の他の縦葺屋根材Ａの嵌合部２を上から押圧することによって、上側の縦葺屋根材Ａの折り返し部１９の先端を下側の縦葺屋根材Ａの被嵌合部３の被係止部１８の外面に沿って下方に移動させると共に上側の縦葺屋根材Ａの突部８を吊子Ｂの支持部４０に当接させた状態で下方に移動させる。これにより、吊子Ｂの支持部４０が固定片９と反対側に向かって傾斜するように弾性変形すると共に、押圧されている嵌合部２が横方向に弾性的に広がった状態で下方へと移動していく。そして、上側の縦葺屋根材Ａの突部８が吊子Ｂの支持部４０の断面略逆Ｕ字状の部分よりも下側に達すると共に上側の縦葺屋根材Ａの折り返し部１９が下側の縦葺屋根材Ａの被嵌合部３の被係止部１８の下側に達すると、押圧されている嵌合部２が復元力（スプリングバック）によって広がった状態からほぼ元の形状に戻り、この結果、吊子Ｂの支持部４０に上側の縦葺屋根材Ａの突部８が弾性的に当接すると共に上側の縦葺屋根材Ａの折り返し部１９が下側の縦葺屋根材Ａの延設片１２と被係止部１８の間に挿入されて被係止部１８に弾性的に係止される。また、上側の縦葺屋根材Ａの載置片１７が吊子Ｂの被載置部６５に載置される。
【００２９】
また、上側の縦葺屋根材Ａの嵌合部２の内側（下側）においてシール材１０が圧縮された状態となって、上側の縦葺屋根材Ａの嵌合部２の内側面（下面）と下側の縦葺屋根材Ａの被嵌合部３のシール密着片３３の上面及び吊子Ｂの支持部４０の上端部とに圧接して密着することになり、嵌合部２と被嵌合部３の間にシール材１０が充填されることになる。また、吊子Ｂの支持部４０の上端に設けた突片５がシール材１０に圧接することになる。
【００３０】
このようにして他の縦葺屋根材Ａの嵌合部２を屋根下地４の上に固定された縦葺屋根材Ａの被嵌合部３とこれに嵌着された吊子Ｂの上部に被嵌することによって、図６に示すように屋根下地４に固定されている縦葺屋根材Ａの被嵌合部３と他の縦葺屋根材Ａの嵌合部２を嵌合させて隣接する縦葺屋根材Ａ、Ａ同士を接続することができる。この後、上記一連の作業を繰り返し行うことによって、複数枚の縦葺屋根材Ａを屋根下地４の上に葺設することによって屋根が形成されるのである。
【００３１】
この実施の形態では上記の実施の形態と同様の効果を奏する他に、支持部４０の上端部に突片５を設け、突片５にてシール材１０を圧接するので、シール材１０を突片５で係止することによってシール材１０の位置が不用意に動かないようにすることができ、特に、シール材１０の長尺方向における位置が不用意に動かないようにすることができ、施工が行い易くなるものである。また、被嵌合部３へ嵌合部２を嵌合する際に、被嵌合部３がシール材１０で上側から押圧されて倒れる方向に変形しかけても、被嵌合部３が突片５に当接させることができ、突片５を被係合部３のストッパーとして作用させて被嵌合部３の変形を防止することができるものであり、被嵌合部３の変形による防水性能の低下を防ぐことができるものである。
【００３２】
尚、吊子Ｂとしては図７に示すように、被載置部６５の部分において支持部４０が途中で若干屈曲しているものを用いても良い。
【００３３】
【発明の効果】
上記のように本発明の請求項１の発明は、一方の側端部に断面略逆Ｕ字状の嵌合部を設けると共に他方の側端部に被嵌合部を設けて縦葺屋根材を形成し、固定部に支持部と係止部とを立設して吊子を形成し、吊子を固定部にて屋根下地に固定すると共に吊子の係止部に縦葺屋根材の被嵌合部を係止し、縦葺屋根材の嵌合部の内側にシール材を挿着し、縦葺屋根材の嵌合部を隣接する縦葺屋根材の被嵌合部に被嵌させることにより被嵌合部の上端部と支持部の上端部にシール材を圧接させて被嵌合部と支持部の支持により嵌合部の内面にシール材を密着して成ることを特徴とするものであり、シール材を被嵌合部と支持部に圧接させて支持することにより嵌合部の内面に密着させることによって、隣接する縦葺屋根材同士の接続部分の防水性能を向上させることができるものである。また、シール材は狭い空間に挿入しないで取り付けることができ、シール材の取り付けを容易に行うことができて作業性を向上させることができるものである。また、シール材は嵌合部の内側に収納することができ、嵌合部の外側にはみ出ないようにして外観を損なわないようにすることができる。
【００３４】
また、本発明の請求項２の発明は、被嵌合部に下側から当接して被嵌合部を支持することにより、シール材の圧接による被嵌合部の下側への変形を防止するための変形防止片を吊子に設けるので、シール材の圧接による被嵌合部の変形を変形防止片で防止することによって、シール材と被嵌合部の密着性が低下しないようにすることができ、防水性能の低下を防止することができるものである。

The part 58 and the contact part 59 are formed so as to face each other.
[0004]
Further, as shown in FIG. 8 (b), the other side end portion of the vertical roofing material A ′ has a substantially arc shape that protrudes upward, and protrudes obliquely upward outward from the side end portion of the roofing material body 1. The arc pieces 60 that are provided in series, the protruding piece 61 that is formed to protrude substantially vertically upward from the tip of the arc piece 60, and the object that is formed to protrude substantially horizontally outward from the tip of the protruding piece 61. The receiving part 62 and the to-be-fitted part 3 provided by projecting the tip of the to-be-received part 62 upward in a substantially inverted V-shaped cross section are configured.
[0005]
9A and 9B show a suspension B ′ for fixing the downright roofing material A ′ to the roof base 4. The hanging roof B 'for the vertical roof material includes a flat plate-like fixing portion 69, a rising portion 70 formed by projecting vertically upward from one side end portion of the fixing portion 69, and a rising portion 70 A sandwiching portion 71 formed by projecting obliquely downward from the upper end in the opposite direction to the fixed portion 69, and a pair of left and right formed projecting from the surface of the rising portion 70 on the fixed portion 69 side to the upper surface of the fixed portion 69 The rib portion 73 and a receiving portion 72 projecting from the surface on the opposite side of the fixed portion 69 of the rising portion 70 between the pair of rib portions 73. Each rib 73 has a recess 74 that is open on both sides, and the upper edge of the recess 74 is a step 77. Further, the rising portion 70 and the sandwiching portion 71 form a groove-shaped engaging portion 75 having a substantially inverted V-shaped cross section, and a receiving portion 72 is formed on the lower side (inner side) of the engaging portion 75. Yes.
[0006]
And when installing the above vertical roof material A ', it carries out as follows. First, the engaging portion 75 of the hanging roof B 'is fitted into the fitted portion 3 of the vertical roofing material A' from above and brought into pressure contact with the engaged portion 75, and the received portion 62 of the vertical roofing material A 'is suspended. A plurality of pieces are placed at predetermined positions on the fitted portion 3 of the vertical roofing material A ′ by placing them on the receiving portion 72 of the child B ′ and elastically locking the outer lower end of the fitted portion 3. Attach the hanger B '. Next, the vertical roofing material A ′ is placed on the roof base 4 such as a field board so that the roof gradient is substantially parallel to the fitting portion 2 and the fitted portion 3.

The vertical roof material A ′ is attached to the roof base 4.
[0007]
Next, another vertical roof material A ′ other than this is connected to the vertical roof material A ′ fixed to the roof base 4. When connecting another vertical roofing material A ′ to the vertical roofing material A ′ fixed to the roof base 4, the upper part is connected to the mated portion 3 of the vertical roofing material A ′ fixed to the roof base 4. Then, the fitting portion 2 of the other vertical roofing material A ′ is fitted, and then the force is applied to the fitting portion 2 by pressing from the upper side by hand or by stepping on the foot. Thus, by applying force from the upper side to the fitting part 2 of the upper vertical roofing material A ′, the fitting part 2 of the upper vertical roofing material A ′ is elastically spread laterally downward. The projecting portion 58 of the upper vertical roofing material A ′ reaches the concave portion 74 of the rib portion 73 of the suspension B ′ and the contact portion 59 of the vertical roofing material A ′ is When reaching the lower part of the sandwiching part 71, the fitting part 2 returns to its original shape from the state expanded by the restoring force (spring back), and the tip of the projection 58 of the upper vertical roofing material A 'is the hanging part B'. The rib portion 73 enters the concave portion 74 and comes into contact with the bottom surface of the concave portion 74, and the abutment portion 59 of the vertical roofing material A ′ is fixed to the sandwiching portion 71 of the suspension B ′ and the roof base 4. The vertical roofing material A ′ is inserted between the receiving part 62 and the vertical roofing material A ′. In this way, on the lower side of the fitting part 2 of the vertical roofing material A ′ arranged on the upper side, the fitted part 3 of the lower vertical roofing material A ′ fixed on the roof base 4 and By fitting the upper portions of the hanging members B ′ fitted thereto, the adjacent vertical roof materials A ′ and A ′ can be connected as shown in FIG. Thereafter, the roof is formed by repeating a series of operations described above and laying a plurality of vertical roof materials A ′ on the roof base 4.
[0008]
In the vertical roofing material A ′ as described above, the waterproofness (watertightness) of the connecting portion is the primary waterproofing by the fitting portion 2 arranged so as to surround the outside, the protrusion 58 and the receiving portion 62. And secondary waterproofing by an internal decompression space (air pocket) 80 formed between the roof base 4 and the roof base 4. In this case, sufficient waterproofness is exhibited against normal wind and rain. However, when it is installed on the roof base 4 with a gentle slope and long in the direction of the eaves, or in the case of a soot leak in the snowy area (ice lacquer that can be formed at the eaves), the height of the connecting part is exceeded. Rainwater may accumulate and a large amount of water may enter the connection area, making it difficult to ensure the waterproofness of the roof.
[0009]
Therefore, the waterproof property is improved with a strip-shaped sealing material 10 as shown in FIG. The sealing material 10 is formed of an elastic body such as rubber, and is pasted over the entire length of the base portion (side surface) of the fitting portion 3 above the receiving portion 62. By fitting the fitting part 2 and the fitted part 3 as shown in FIG. 12, the tip of the contact part 59 of the fitting part 2 comes into close contact with the sealing material 10 as shown in FIG. It is intended to improve the performance.
[0010]
[Problems to be solved by the invention]
However, it is very difficult to attach the sealing material 10 to the base portion of the fitted portion 3 as described above during and after the vertical roof material A ′. That is, if the sealing material 10 is to be attached to the base of the fitted portion 3, the sealing material 10 must be inserted into the narrow gap between the tip (outer lower end) of the fitted portion 3 and the receiving portion 62. In addition, it is dangerous because the tip of the fitted portion 3 protrudes like a blade, and the base of the fitted portion 3 is in a position that is difficult to see from above. Affixing the material 10 was very difficult and time consuming. In particular, after the vertical roof material A ′ is lifted on the roof base 4, it becomes a work at a high place and the pasting work becomes more difficult.
[0011]
The present invention has been made in view of the above points, can improve the waterproofness of the roof, can easily attach the sealing material, can improve workability, An object of the present invention is to provide a connection structure for downpipe roofing material that can prevent the appearance from being impaired.

The upper end of the deformation preventing piece 7 is formed in a substantially triangular shape, and the upper end of the deformation preventing piece 7 and the upper end of the locking portion 20 are formed so as to be located at substantially the same height.
[0019]
Next, a construction example in which the vertical roofing material A is installed using the above-described suspension B will be described. First, one side end portion of the vertical roofing material A is inserted by inserting (pressing) the locking portion 20 of the hanging element B into the locked portion 18 of the fitted portion 3 of the vertical roofing material A from above. A plurality of suspensions B are attached at predetermined locations along the line. The hanging elements B are preferably attached at a constant pitch such as an interval of about 600 mm. On the other hand, on the inner side (lower side) of the fitting portion 2 of another vertical roofing material A different from the vertical roofing material A, as shown in FIG. Is inserted into the fitting portion 2 from its lower opening and is stored over the entire length of the fitting portion 2. The sealing material 10 is an elastic body such as rubber and is formed in a long cylindrical shape or the like, and is the same as or slightly smaller than the space inside (lower side) of the fitting portion 2 having a substantially U-shaped cross section. It has a diameter. The suspension B and the sealing material 10 are preferably attached to the downright roofing material A on the ground. This can reduce the danger by reducing the work at a high place. Of course, the above work may be performed on the roof base 4.
[0020]
Next, a large number of vertical roof materials A are conveyed onto the roof base 4 such as a field plate by a crane or the like. Next, the vertical roof material A is placed so that the upper surface of the roof base 4 and the fitting part 2 and the fitted part 3 are substantially parallel. Next, the hanging element B is roofed by driving a fixing tool 47 such as a nail or a screw into the roof base 4 through a through hole 44 provided in the fixing part 9 of each hanging element B attached to the vertical roofing material A. By fixing to the base 4, the vertical roof material A is attached and fixed to the roof base 4 via a plurality of hanging elements B.
[0021]
Next, another vertical roof material A different from this is connected to the vertical roof material A fixed to the roof base 4. In connecting another vertical roof material A to the vertical roof material A fixed on the roof base 4, as shown in FIG. 4A, the lower vertical surface fixed to the roof base 4 is used. The mating portion 3 of the roofing roof material A is covered with the mating portion 2 of another vertical roofing roof material A from above, and a force is applied to the fitting portion 2 by pressing it with hands or stepping on it with feet. In this way, by pressing the fitting portion 2 of the other upright roofing material A from above, the tip of the folded portion 19 of the upper upright roofing material A is fitted to the lower upright roofing material A. While moving downward along the outer surface of the locked portion 18 of the joint portion 3, the protrusion 8 of the upper vertical roofing material A is moved downward in a state of being in contact with the support portion 40 of the suspension B. Thereby, as shown in FIG.4 (b), while the support part 40 of the suspension B is elastically deformed so that it may incline toward the opposite side to the fixed piece 9, the pressed fitting part 2 is horizontal direction. It moves downward while elastically spreading. And the protrusion 8 of the upper vertical roofing material A reaches the lower side of the substantially inverted U-shaped section of the support portion 40 of the suspension B, and the folded portion 19 of the upper vertical roofing material A is lower. When it reaches the lower side of the locked portion 18 of the fitted portion 3 of the side vertical roofing material A, it returns to the original position so that the support portion 40 of the hanging piece B is inclined toward the fixed piece 9 side. At the same time, the pressed fitting portion 2 returns to its original shape from the state where it is expanded by the restoring force (springback), and as a result, the protrusion of the upper vertical roofing material A on the support portion 40 of the suspension B 8 is elastically contacted, and the folded portion 19 of the upper vertical roofing material A is inserted between the extended piece 12 of the lower vertical roofing material A and the locked portion 18 to be locked. It is elastically locked to.
[0022]
Moreover, the sealing material 10 is in a compressed state on the inner side (lower side) of the fitting portion 2 of the upper vertical roofing material A, and the inner side surface (lower surface) of the fitting portion 2 of the upper vertical roofing material A ) And the upper surface of the seal contact piece 33 of the fitted portion 3 of the lower vertical roofing material A, the outer surface of the locked portion 18, and the upper end portion of the support portion 40 of the hanging member B. Thus, the sealing material 10 is filled between the fitting portion 2 and the fitted portion 3. At this time, the fitted portion 3 of the lower vertical roofing material A is pressed from above by the sealing material 10 and tends to be deformed downward, but below the seal contact piece 33 of the fitted portion 3. Since the bent portion 34 formed on the side abuts against the upper end of the deformation preventing piece 7 and the fitted portion 3 is supported, the downward deformation of the fitted portion 3 is prevented.
[0023]
In this way, the fitting part 2 of the other vertical roofing material A is fitted on the fitted part 3 of the vertical roofing material A fixed on the roof base 4 and the upper part of the hanging element B fitted thereto. By fitting, the fitted portion 3 of the vertical roofing material A fixed to the roof base 4 and the fitting portion 2 of the other vertical roofing material A are fitted to each other as shown in FIG. The vertical roof materials A and A can be connected to each other. Thereafter, by repeating the above-described series of operations, the roof is formed by laying a plurality of vertical roof materials A on the roof base 4.
[0024]
As described above, in the connection structure of the vertical roof material A according to the present invention, the sealing material 10 is brought into close contact with the inner surface of the fitting portion 2 by being pressed against and supported by the fitted portion 3 and the support portion 40. It is possible to improve the waterproof performance of the connecting portion between the adjacent vertical roof materials A. Further, in the present invention, since the sealing material 10 is stopped at the top of the connecting portion above the decompression space (air pocket) 80, rainwater does not easily reach the portion of the sealing material 10 even if rainwater accumulates. The waterproof property can be remarkably improved as compared with the case where the sealing material 10 is provided at the position of the conventional example. In addition, the fitting portion 3 that is pressed from above by the sealing material 10 is supported from below by the deformation preventing piece 7 to prevent the fitting portion 3 from being deformed downward. It is possible to prevent a gap from being formed between the fitting portion 3 and maintain high adhesion between the sealing material 10 and the fitted portion 3 and prevent a decrease in waterproof performance.
[0025]
Further, by storing the sealing material 10 inside the fitting portion 2 and attaching it to the vertical roofing material A, it is possible to attach the sealing material 10 without inserting it into a narrow space as in the conventional example, and the sealing material 10 can be easily attached. It can be performed and workability can be improved. In addition, in the conventional example, the sealing material 10 may be exposed to the outside from between the contact portion 59 and the receiving portion 62 due to variations in the position of the pasted sealing material 10. In the present invention, even if the sticking position of the sealing material 10 is slightly deviated, there is no external exposure and the appearance can be kept intact, and the design can be improved. .
[0026]
5 (a) to 5 (c) show other examples of the suspension B for fixing the vertical roof material A to the roof base 4. FIG. The suspension B is formed by providing a locking portion 20 and a pair of support portions 40 on a flat plate-like fixing portion 9. The support portion 40 is formed so as to protrude obliquely upward from one side end portion of the fixed portion 9, and the upper portion thereof is formed in a substantially inverted U shape in cross section. Further, a protruding piece 5 is formed at the upper end of the support portion 40 so as to protrude obliquely upward. The projecting piece 5 is formed by cutting and raising a part of an upper bent portion of the support portion 40. In addition, a placement portion 65 is projected from the surface of the support portion 40 on the fixed portion 9 side. Furthermore, the rib part 73 of the fixing | fixed part 9 and the support part 40 is protrudingly provided. The locking portion 20 is provided between the pair of support portions 40, and protrudes from the one side end portion of the fixing portion 9 to the opposite side of the fixing portion 9 and upward. The upper part is formed in the substantially U-shaped cross section. In addition, a rib portion 73 projects from the bent portion of the locking portion 20.
[0027]
Next, a construction example in which the vertical roofing material A is installed using the hanging element B will be described. First, the engaging part 20 of the hanging element B is inserted into the engaged part 18 of the fitted part 3 of the vertical roofing material A from above, along one side end of the vertical roofing material A. A plurality of suspensions B are attached to predetermined places. The hanging elements B are preferably attached at a constant pitch such as an interval of about 600 mm. When the hanging element B is attached to the vertical roofing material A as described above, the tip of the protruding piece 5 of the hanging element B and the end of the seal contact piece 33 of the fitted portion 3 of the vertical roofing material A Are close to each other so as to face each other. On the other hand, a sealing material 10 similar to the above is applied to the inside (lower side) of the fitting portion 2 of the other vertical roofing material A different from the vertical roofing material A over the entire length of the fitting portion 2. Store. Next, a large number of vertical roof materials A are conveyed onto the roof base 4 such as a field plate by a crane or the like. Next, the vertical roof material A is placed so that the upper surface of the roof base 4 and the fitting part 2 and the fitted part 3 are substantially parallel. Next, the hanging element B is roofed by driving a fixing tool 47 such as a nail or a screw into the roof base 4 through a through hole 44 provided in the fixing part 9 of each hanging element B attached to the vertical roofing material A. By fixing to the base 4, the vertical roof material A is attached and fixed to the roof base 4 via a plurality of hanging elements B.
[0028]
Next, another vertical roof material A different from this is connected to the vertical roof material A fixed to the roof base 4. In connecting another vertical roof material A to the vertical roof material A fixed on the roof base 4, the fitted portion 3 of the lower vertical roof material A fixed to the roof base 4 A fitting portion 2 of another vertical roof material A is covered from above, and force is applied to the fitting portion 2 by pressing it from above or stepping on it with a foot. In this way, by pressing the fitting portion 2 of the other upright roofing material A from above, the tip of the folded portion 19 of the upper upright roofing material A is fitted to the lower upright roofing material A. While moving downward along the outer surface of the locked portion 18 of the joint portion 3, the protrusion 8 of the upper vertical roofing material A is moved downward in a state of being in contact with the support portion 40 of the suspension B. Thereby, while the support part 40 of the suspension B is elastically deformed so as to incline toward the opposite side to the fixed piece 9, the pressed fitting part 2 is elastically expanded in the lateral direction downward. And move on. And the protrusion 8 of the upper vertical roofing material A reaches the lower side of the substantially inverted U-shaped section of the support portion 40 of the suspension B, and the folded portion 19 of the upper vertical roofing material A is lower. When it reaches the lower side of the locked portion 18 of the fitted portion 3 of the vertical vertical roofing material A, the pressed fitting portion 2 is substantially in its original shape from the state where it is spread by the restoring force (spring back). As a result, the protruding portion 8 of the upper vertical roofing material A is in elastic contact with the support portion 40 of the suspension B and the folded portion 19 of the upper vertical roofing material A is the lower vertical roofing. The material A is inserted between the extended piece 12 and the locked portion 18 and is elastically locked to the locked portion 18. Further, the placing piece 17 of the upper vertical roofing material A is placed on the placement portion 65 of the hanging element B.
[0029]
