【発明の属する技術分野】
本発明は、軒樋の接続構造に関する発明である。
【０００２】
【従来の技術】
従来から、軒樋１にあっては、図９に示すように、屋外側に位置して立設した軒樋前壁部１１と、建物側に位置して立設した軒樋後壁部１４と、上記軒樋前壁部１１の下端と軒樋後壁部１４の下端とを連結した軒樋底壁部１５とで縦断面Ｕ字状に主体が形成されている。なお、軒樋前壁部１１の上端には前耳部１６が設けられ、また、軒樋後壁部１４の上端には後耳部１７が設けられている。上記軒樋前壁部１１は屋外側に露出される部位であるから、軒樋前壁部１１は軒樋１の外観を現出させる部位であり、つまり軒樋前壁部１１には軒樋１の外観の向上に資するような形状が求められる。また、屋外側に露出される軒樋前壁部１１は雨水が降りかかる部位であるが、上記軒樋前壁部１１に降った雨水を軒樋１の下方に滴り落としてしまうことは好ましくない。しかして、軒樋前壁部１１は、軒樋前壁部１１の上部を構成する上部軒樋前壁部１２と軒樋前壁部１１の下部を構成する下部軒樋前壁部１３との間に後方且つ下方に凹没させた軒樋排水溝１８を軒樋１の長手方向に亙って形成させて構成されている。ここで、上部軒樋前壁部１２は下方程前方に位置するように傾斜をした板片であり、軒樋前壁部１１に降りかかる雨水を積極的に受けると共に上記雨水を軒樋排水溝１８に流し込むものであり、また、下部軒樋前壁部１３は下方程後方に位置するように傾斜をした板片であり、軒樋前壁部１１に降りかかる雨水を受けにくいようにしている。このように軒樋前壁部１１を上部軒樋前壁部１２及び下部軒樋前壁部１３で構成させると共に、上部軒樋前壁部１２と下部軒樋前壁部１３との間に軒樋排水溝１８を設けたことで、上記軒樋排水溝１８が軒樋１の長手方向に亙って軒樋１の外観に統一的なアクセントをつけることから軒樋１の外観の向上が為されるものであり、同時に、軒樋前壁部１１に降りかかる雨水を軒樋排水溝１８に流れ込ませて上記雨水の軒樋１の下方への流下を防止しているのである。
【０００３】
このような構造を有した軒樋１は、互いにその長手方向の端部を対向させて隣接させた軒樋１間に配置した軒樋継手２’によって接続されるものである。つまり軒樋継手２’ではその左右両端にそれぞれ軒樋１の長手方向の端部が接続され、軒樋１同士を上記軒樋継手２’を介在させて連結させる。この軒樋継手２’にあっては図８に示すものがある。軒樋継手２’はその内面で軒樋１の外面を包み込むようにし、つまり軒樋継手２’の内面に軒樋１の外面を沿わせて嵌め込むものであるから、軒樋継手２’の主体の縦断面形状は軒樋１と略同形状で且つ軒樋１の縦断面に対して一廻り大きな形状になっている。つまりこの軒樋継手２’は、屋外側に位置して立設した継手前壁部２１と、建物側に位置して立設した継手後壁部２４と、上記継手前壁部２１の下端と継手後壁部２４の下端とを連結した継手底壁部２５とで主体が構成されている。ここで、継手前壁部２１にあっては、軒樋１の軒樋前壁部１１の外面に沿わせるため、上下方向の中央部分が前方に突出するような縦断面略弧状に形成されていると共に、継手前壁部２１の上部に降りかかった雨水を軒樋継手２’に接続した軒樋１の軒樋排水溝１８に流し込むため、軒樋継手２’に接続した軒樋１の軒樋排水溝１８に連続する継手排水溝２８を継手前壁部２１の外面から凹没させるように形成している。なお、継手前壁部２１の上端には前耳部１６を係合するフック状の前耳係合部２６が設けられ、また、継手後壁部２４の上端には後耳部１７を係合するフック状の後耳係合部２７が設けられている。また、継手後壁部２４及び継手前壁部２１の内面には内方に突出した規制突起部４が設けられている。この規制突起部４は、軒樋継手２’の左右両端からそれぞれ挿入される軒樋１の挿入深さを規制して軒樋継手２’内に対向して配置した軒樋１間に間隔を形成させるものであり、つまり軒樋１の軒樋排水溝１８に流れる雨水を軒樋継手２’内に流下させる流路を確保しているのである。
【０００４】
上述したように軒樋継手２’の左右端部からそれぞれ軒樋１を挿入し、軒樋継手２’に１対の軒樋１を接続した状態にあっては、同じく図８に示すように、軒樋継手２’の左右端部から挿入したそれぞれの軒樋１の挿入先端である長手方向の端部を規制突起部４に当接させると共に、軒樋継手２’の前耳係合部２６及び後耳係合部２７がそれぞれの軒樋１の前耳部１６及び後耳部１７を係合させて軒樋継手２’の内面に軒樋１の外面を密着させた状態で行われる。ここで、軒樋継手２’の継手前壁部２１と軒樋１の軒樋前壁部１１との積層状態にあっては継手排水溝２８が軒樋排水溝１８の外側に嵌合するようになっている。継手排水溝２８が軒樋排水溝１８に嵌合することは、軒樋１が接続される軒樋継手２’の左右端部において継手排水溝２８と軒樋１の軒樋排水溝１８とが連続することであり、しかして、軒樋継手２’の軒樋前壁部１１の外面で受けて継手排水溝２８に流入した雨水は上記継手排水溝２８の左右端部から軒樋排水溝１８に流入するものである。そして、上記継手排水溝２８から流入した雨水を含めて軒樋排水溝１８に流れる雨水は、軒樋継手２’の内側に位置する軒樋排水溝１８の長手方向の端部から軒樋継手２’の内部に流入するものである。このように、軒樋継手２’の継手前壁部２１や軒樋１の軒樋前壁部１１に降った雨水は、継手排水溝２８や軒樋排水溝１８を介して軒樋継手２’内に流入させることができ、軒樋継手２’や軒樋１から雨水を滴り落とすといったことが防止されているのである。
【０００５】
【発明が解決しようとする課題】
しかしながら、継手排水溝２８を軒樋排水溝１８に嵌合させるということは、軒樋排水溝１８の前面の開口を継手排水溝２８で塞ぐといったことになり、つまり軒樋継手２’の内側に位置した軒樋排水溝１８は縦断面管状になるものであるから、上記部分の軒樋排水溝１８には枯葉等のゴミが溜まって詰まり易く、雨水の軒樋継手２’内への流入が阻害されるといった問題が生じるものであった。また、軒樋継手２’の内側に位置する軒樋排水溝１８の流路をなるべく大きくとるようにするため、継手排水溝２８の凹没量は軒樋排水溝１８の凹没量に比べて浅く形成されることから、連続する軒樋排水溝１８と継手排水溝２８とが現出させる外観にあっては上記両溝の凹没量の相違から多少の違和感を現出させてしまうといった問題があった。
【０００６】
本発明は上記の点に鑑みてなされたものであり、軒樋前壁部に長手方向に亙って軒樋排水溝が形成された軒樋を軒樋継手を介して接続させる軒樋の接続構造において、違和感のない外観を現出させると共に上記軒樋や軒樋継手に降りかかる雨水の軒樋の下方への流下を防止できるような軒樋の接続構造を提供することを課題とするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明に係る軒樋の接続構造にあっては、屋外側に位置する軒樋前壁部１１に降りかかった雨水を軒樋１の下方に流下させないように、上記軒樋前壁部１１にその長手方向に亙って内方に凹没させた軒樋排水溝１８を設けて構成した軒樋１を長手方向の端部を対向させて配置すると共に、上記対向する軒樋１同士の間に配置した軒樋継手２の左右端部の内面にそれぞれ軒樋１の外面を沿わせて接続させたことで軒樋１を接続した軒樋の接続構造において、軒樋１の軒樋前壁部１１の外面に沿わせる軒樋継手２の継手前壁部２１を上下に２分割し、上記２分割して形成した上部継手前壁部２２と下部継手前壁部２３とを上下に間隔を隔てて左右に広い幅寸法を有した薄板６ａで構成した連結部６で連結し、軒樋継手２内に挿入した軒樋１の長手方向の端部を上記連結部６の幅方向の端部に当接させて対向する軒樋１間に間隔を形成し、上部継手前壁部２２と下部継手前壁部２３との隙間５を上記軒樋１の軒樋排水溝１８に重ねて位置させて上記軒樋排水溝１８を外方に露出させ、前後方向に広い幅寸法を有し且つ左右方向に薄い肉厚を有した薄板６ｅでなる垂下片６４を有した補強用リブ９を上記連結部６の左右中央部分に上下に亘るように設けたことを特徴とする。これによると、軒樋継手２に軒樋１を接続した際に重なり合う軒樋１の軒樋前壁部１１と軒樋継手２の継手前壁部２１との間では、軒樋継手２の軒樋前壁部１１を構成する上部継手前壁部２２と下部継手前壁部２３との隙間５が軒樋１の軒樋排水溝１８に重ねて位置され、上記軒樋排水溝１８が外方に露出されることになるから、軒樋継手２の内側に位置する軒樋排水溝１８も他の部分同様に屋外側に露出される状態になっており、しかして、軒樋排水溝１８内でのごみ等の詰まりの発生を抑えて軒樋排水溝１８を流れる雨水の軒樋継手２内への流入を良好に維持でき、軒樋１や軒樋継手２に降りかかる雨水の軒樋１の下方への流下を防止できるものであると共に、軒樋１を接続させた軒樋継手２の外観にあっては軒樋１の長手方向及び軒樋継手２の左右方向に亙って軒樋排水溝１８を屋外側に現出させるものであり、違和感のない統一感のある外観を現出できるものである。また、軒樋排水溝１８を備えた軒樋１を接続させる軒樋継手２には、軒樋排水溝１８を流れる雨水を軒樋継手２内に流入させる流路を確保するために、軒樋継手２の左右両端からそれぞれ挿入される軒樋１の挿入深さを規制して軒樋継手２内に対向して配置した軒樋１間に上記流路として機能させる間隔を形成させる規制突起部４が必要不可欠なものであるが、上部継手前壁部２２と下部継手前壁部２３とを連結する連結部６に軒樋継手２内に挿入した軒樋１の長手方向の端部を当接させて対向する軒樋１間に間隔を形成している、つまり連結部６に規制突起部４の機能をも付加させており、しかして軒樋継手２を構成する部品点数の増加が抑制され、軒樋継手２の構成の簡易化が図られているのである。また、連結部６の上下に亘るように設けた補強用リブ９により、連結部６の剛性補強、ひいては軒樋継手２の継手前壁部２１及び軒樋継手２に接続した軒樋１の軒樋前壁部１１の剛性の向上を図ることができる。また、補強用リブ９を構成する前後方向に広い幅寸法を有し且つ左右方向に薄い肉厚を有した薄板６ｅでなる垂下片６４は、各軒樋１，１の軒樋排水溝１８，１８間を塞ぐ格好に位置されるが、この垂直片６４は連結部６の左右中央部分に設けられていることから、軒樋１の軒樋排水溝１８の長手方向の端部を塞いでしまうことはなく、各軒樋１，１の軒樋排水溝１８，１８から対向方向に流れ込む雨水の障壁として機能し、一方の軒樋排水溝１８に流れる雨水を対向する他の軒樋排水溝１８に至らせないようにできると共に、軒樋１の軒樋排水溝１８を流れる雨水を滞りなく軒樋継手２内に流下させるようにできるのである。
【０００８】
また、連結部６に軒樋排水溝１８に流れる雨水を伝わせて軒樋継手２内に流下させる機能を持たせたことも好ましい。これによると、軒樋排水溝１８を流れる雨水が軒樋継手２内に流入する際に、上記雨水が連結部６の板面を伝ってスムーズに軒樋継手２内に流入することができるものである。
【０００９】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。本発明は、従来技術で示した軒樋前壁部１１に軒樋排水溝１８を設けて構成された軒樋１（図９参照）を、以下に述べる軒樋継手２を用いて接続させる軒樋の接続構造であることから、軒樋１の説明はここでは省き、軒樋継手２につき重点的に説明をしていくものとする。
【００１０】
図１乃至図５に本発明にかかる参考例を示す。図２及び図３に示すように本例の軒樋継手２は、従来技術の軒樋継手２’同様その主体は屋外側に位置して立設した継手前壁部２１と、建物側に位置して立設した継手後壁部２４と、上記継手前壁部２１の下端と継手後壁部２４の下端とを連結した継手底壁部２５とで構成されているも、上記継手前壁部２１にあっては上下に２分割してある。つまり継手前壁部２１は、継手前壁部２１の上部を構成する上部継手前壁部２２と、継手前壁部２１の下部を構成する下部継手前壁部２３とで構成されている。この上部継手前壁部２２と下部継手前壁部２３とは上下に間隔を隔てて隙間５を形成するように配置され、上記隙間５を隔てて配置された上部継手前壁部２２と下部継手前壁部２３とは軒樋継手２の内側で軒樋継手２の左右方向の中央部分に設けた連結部６によって一体に連結されている。なお、上部継手前壁部２２は軒樋１の上部軒樋前壁部１２の外面に沿わせる軒樋継手２の部位であり、また、下部継手前壁部２３は軒樋１の下部軒樋前壁部１３の外面に沿わせる軒樋継手２の部位であることから、上部継手前壁部２２の下端は下部継手前壁部２３の上端よりも後方に位置するようになっており、上部継手前壁部２２に降りかかった雨水は上部継手前壁部２２の下端から滴り落ち、隙間５を通って下部継手前壁部２３の内面、つまり軒樋継手２内に至るようにしてある。なお、上部継手前壁部２２の上端及び継手後壁部２４の上端には内方に屈曲させて形成された前耳係合部２６及び後耳係合部２７が設けられており、また継手後壁部２４の内面には内方に突出したブロック状の規制突起部４が設けられている。
【００１１】
ここで、連結部６は、具体的に軒樋継手２の左右方向に広い幅寸法を有し且つ上下方向に薄い肉厚を有した薄板６ａによって形成されている。詳述すると、薄板６ａが上部継手前壁部２２の下端から後方且つ下方に延出し、その下方に向けて延伸する上記薄板６ａが下部継手前壁部２３の後方に至った部分で前方且つ上方または前方に折れ曲がり、そして前方且つ上方または前方に向けて延伸する上記薄板６ａが下部継手前壁部２３の内面に一体に連結することで、本例の連結部６を形成させている。
【００１２】
上述したように軒樋１を接続させるには軒樋継手２を用いて行わせるものであるが、上記構成を有する本例の軒樋継手２でもその左右両端からそれぞれ軒樋１を挿入し、軒樋継手２に軒樋１をそれぞれ接続させることで、隣接する軒樋１を接続させるのである。軒樋継手２に軒樋１を接続した状態を図１に示す。この軒樋継手２も従来技術の軒樋継手２’同様に、継手前壁部２１の上端（上部継手前壁部２２の上端）の前耳係合部２６を軒樋１の前耳部１６の上方から係合させると共に継手後壁部２４の上端の後耳係合部２７を軒樋１の後耳部１７の上方から係合させることで、軒樋継手２の左右端部からそれぞれ挿入した軒樋１を下方に押さえ付けるものであって、軒樋１はその外面を軒樋継手２の内面に沿わせるようにして固定される。ここで、軒樋前壁部１１と継手前壁部２１との積層部分につき詳述すると、上部軒樋前壁部１２が上部継手前壁部２２の外面に積層すると共に下部軒樋前壁部１３が下部継手前壁部２３の外面に積層するものであり、そして上部継手前壁部２２と下部継手前壁部２３との隙間５が軒樋排水溝１８の前方に位置しているのである。つまり、軒樋排水溝１８は軒樋１が軒樋継手２に接続されている部位に関わらず外方に露出されているのである。これによると、軒樋継手２に軒樋１を接続させた状態の外観にあっては、軒樋１の長手方向及び軒樋継手２の左右方向に亙って軒樋排水溝１８を屋外側に現出させることができ、違和感のない統一感のある外観を現出させることができるものである。また、外方に露出された軒樋排水溝１８はつまり開放空間になっていることから、軒樋排水溝１８内でのごみ等の詰まりの発生を抑えて軒樋排水溝１８を流れる雨水の軒樋継手２内への流入を良好に維持できるものである。なお、軒樋１を接続した軒樋継手２の上部継手前壁部２２に降りかかった雨水は、隙間５を通って軒樋排水溝１８内に滴り落ちて軒樋排水溝１８を介して軒樋継手２内に流入されるかまたは連結部６を伝って直接軒樋継手２内に流入されるものであり、つまり軒樋継手２に降りかかる雨水の軒樋継手２の下方への流下が確実に防止されているのである［図４（ｂ）］。
【００１３】
また、上述したように軒樋１を軒樋継手２に接続する際には軒樋継手２の左右端部からそれぞれ軒樋１を挿入させるものであるが、本例の軒樋継手２に軒樋１を挿入するにあたっては連結部６の幅方向の端部に軒樋１の長手方向の端部を当接させるまで軒樋継手２の左右端部からそれぞれ軒樋１を挿入させるようにして行われる。つまり連結部６には、上部継手前壁部２２と下部継手前壁部２３とを連結させる機能の他に、軒樋排水溝１８を流れる雨水を軒樋継手２内に流入させる流路を確保するために軒樋継手２内に対向して配置した軒樋１間に間隔を形成させるといった従来技術にある規制突起部４の機能をも付加させているのである。このように連結部６に規制突起部４の役割を担わせたことで規制突起部４の設置個数を減らすことができ、つまりは軒樋継手２を構成する部品点数の増加を抑制するものであり軒樋継手２の構成の簡易化が図られているのである。ここで、本例の連結部６の幅方向端部が軒樋１の長手方向の端部に当接する部分にあっては、図１に示すように軒樋排水溝１８の長手方向の端部である。つまり連結部６を形成する薄板６ａのうち上部継手前壁部２２の下端から後方且つ下方に延出するような部位が、側面視で軒樋排水溝１８の底部に対して交差するように当接している。このようにすることで、図４（ａ）（ｃ）に示すように、軒樋排水溝１８に流れる雨水は連結部６を伝って軒樋継手２内に流れ込むものであり、つまり軒樋排水溝１８から軒樋継手２内に雨水をスムーズに流れ込ませることが図られているのである。
【００１４】
なお、軒樋継手２と軒樋１との更なる密着を図るため、図５に示すように、軒樋継手２に接続した軒樋１を更に下方に押さえ付ける内押え部材３を配置してもよい。この内押え部材３は、軒樋前壁部１１の内面に沿わせる内押え前壁部３１と、軒樋後壁部１４の内面に沿わせて後耳部１７によって下方に押さえ付けられる内押え後壁部３２とを有し、軒樋底壁部１５の内面に沿わせる内押え底壁部３３で上記内押え後壁部３２と内押え前壁部３１とを連結し、上記内押え底壁部３３から斜め後方に立設して軒樋前壁部１１の前耳部１６に沿わせると共に継手前壁部２１の前耳係合部２６の後端部分によって上方から押さえ付けられる押圧片３４を備えて構成されている。ここで、押圧片３４は下方程前方に位置する傾斜状に形成されているから、継手前壁部２１の前耳係合部２６によって押さえ付けられた押圧片３４は内押え底壁部３３の前半部分及び内押え前壁部３１を前方且つ下方に押圧させ、また、内押え後壁部３２は前方程下方に位置する傾斜面である後耳部１７の下面により下方に押さえ付けられるので、内押え後壁部３２及び内押え底壁部３３の後半部分を後方且つ下方に押圧させるのである。このように内押え部材３は軒樋１を軒樋継手２の全内面に亙って押圧させるものであり、軒樋１の外面の軒樋継手２の内面への更なる密着を図ることができるのである。
【００１５】
図６及び図７には本発明の実施の形態の例を示す。この例は、軒樋継手２における上部継手前壁部２２と下部継手前壁部２３とを一体に連結する連結部６に、上下に亘る補強用リブ９を形成し、連結部６の剛性補強、ひいては軒樋継手２の継手前壁部２１及び軒樋継手２に接続した軒樋１の軒樋前壁部１１の剛性の向上を図るようにした例である。先の実施の形態の例や他例と同様部分は同一符号を付して説明を省き、相違する部分のみを説明する。
【００１６】
図６に示すように、本例の連結部６は、先の参考例と同様に、左右方向に広い幅寸法を有した薄板６ａによって後方に凹となる略コ字状の主体部６１が形成されている。そして、この主体部６１に加え、この主体部６１の後端部分から、水平板部６２を略水平後方に延出すると共に垂直板部６３を略垂直上方に延出している。この水平板部６２は左右方向に広い幅寸法を有し且つ上下方向に薄い肉厚を有した薄板６ｃにて構成されており、垂直板部６３は左右方向に広い幅寸法を有し且つ前後方向に薄い肉厚を有した薄板６ｄで構成されている。この垂直板部６３は上部継手前壁部２２の内面と主体部の後端部分とを連結するように形成されている。また、この連結部６における、垂直板部６３及び主体部６１の後端より下位部分には、垂直片６４が形成されている。この垂直片６４は、前後方向に広い幅寸法を有し且つ左右方向に薄い肉厚を有した薄板６ｅで構成されており、連結部６の左右の中央部分から前後に延出されている。詳述すると、この垂直片６４は、上部継手前壁部２２と水平板部６２の上面と垂直板部６３の後面とを連結する上部垂直片６４ａと、主体部６１の後端より下位部分の後面と水平板部６２の下面とを連結する下部後側垂直片６４ｂと、主体部６１の後端より下位部分の前面と下部継手前壁部２３と内面とを連結する下部前側垂直片６４ｃとで構成されている。
【００１７】
このように本例の連結部６は、主体部６１に加えて、垂直片６４、垂直板部６３及び水平板部６２とを有して構成されている。この垂直片６４、垂直板部６３及び水平板部６２は連結部６の上下方向の撓みを防止する補強用リブ９を構成している。つまり、薄板６ａで成る主体部６１によっては、連結部６に、先の実施の形態の例同様、上部継手前壁部２２と下部継手前壁部２３とを連結する機能及び従来技術にある規制突起部４の機能を持たせているものであり、また、連結部６の上下に亘って上部継手前壁部２２と下部継手前壁部２３とを連結する補強用リブ９によっては、連結部６に、特に上下への撓みを防止するような剛性の向上機能を持たせているものである。したがって、補強用リブ９によって剛性の向上が図られた本例の連結部６は、軒樋継手２の継手前壁部２１、ひいては軒樋継手２に接続した軒樋１の軒樋前壁部１１の上下撓みを防止し、軒樋継手２を介した軒樋１の接続構造の剛性の向上が図られているのである。
【００１８】
なお、この連結部６は、図７に示すように、軒樋継手２に接続した軒樋１，１の軒樋排水溝１８，１８間に位置している。しかして、軒樋１の軒樋排水溝１８を流れる雨水は、連結部６を伝って、軒樋継手２内に流れ込むようにされている。このとき、垂直片６４は各軒樋１，１の軒樋排水溝１８，１８間を塞ぐ格好に位置されるが、この垂直片６４は連結部６の左右中央部分に設けられていることから、軒樋１の軒樋排水溝１８の長手方向の端部を塞いでしまうことはなく、各軒樋１，１の軒樋排水溝１８，１８から対向方向に流れ込む雨水の障壁として機能し、一方の軒樋排水溝１８に流れる雨水を対向する他の軒樋排水溝１８に至らせないようにできると共に、軒樋１の軒樋排水溝１８を流れる雨水を滞りなく軒樋継手２内に流下させるようにできるのである。
【００１９】
【発明の効果】
本発明の請求項１記載の発明にあっては、叙述したように、軒樋の軒樋前壁部の外面に沿わせる軒樋継手の継手前壁部を上下に２分割し、上記２分割して形成した上部継手前壁部と下部継手前壁部とを上下に間隔を隔てて連結部で連結し、上部継手前壁部と下部継手前壁部との隙間を上記軒樋の軒樋排水溝に重ねて位置させて上記軒樋排水溝を外方に露出させたので、軒樋継手の内側に位置する軒樋排水溝も他の部分同様に屋外側に露出される状態になっており、しかして、軒樋排水溝を開放空間にして軒樋排水溝内でのごみ等の詰まりの発生を抑えて軒樋排水溝を流れる雨水の軒樋継手内への流入を良好に維持し、上記軒樋や軒樋継手に降りかかる雨水の軒樋の下方への流下を防止できるようにすると共に、軒樋を接続させた軒樋継手の外観にあっても軒樋の長手方向及び軒樋継手の左右方向に亙って軒樋排水溝を屋外側に現出させるものであるから違和感のない統一感のある外観を現出できるものである。また、軒樋継手内に挿入した軒樋の長手方向の端部を左右に広い幅寸法を有した薄板で構成した連結部の幅方向の端部に当接させて対向する軒樋間に間隔を形成したので、軒樋排水溝を流れる雨水を軒樋継手内に流入させる流路を確保でき、つまりは連結部に上部継手前壁部と下部継手前壁部とを連結させる機能の他に、軒樋継手の左右両端からそれぞれ挿入される軒樋の挿入深さを規制して軒樋継手内に対向して配置した軒樋の間に上述した軒樋排水溝に流れる雨水を軒樋継手内に流入させる流路としての間隔を形成させる規制突起部の機能をも付加させるものであり、しかして軒樋継手を構成する部品点数の増加が抑制され、軒樋継手の構成の簡易化を図ることができるのである。また、連結部の上下に亘るように設けた補強用リブにより、連結部の剛性補強、ひいては軒樋継手の継手前壁部及び軒樋継手に接続した軒樋の軒樋前壁部の剛性の向上を図ることができる。また、補強用リブを構成する前後方向に広い幅寸法を有し且つ左右方向に薄い肉厚を有した薄板でなる垂下片は、各軒樋の軒樋排水溝間を塞ぐ格好に位置されるが、この垂直片は連結部の左右中央部分に設けられていることから、軒樋の軒樋排水溝の長手方向の端部を塞いでしまうことはなく、各軒樋の軒樋排水溝から対向方向に流れ込む雨水の障壁として機能し、一方の軒樋排水溝に流れる雨水を対向する他の軒樋排水溝に至らせないようにできると共に、軒樋の軒樋排水溝を流れる雨水を滞りなく軒樋継手内に流下させるようにできるのである。
【００２０】
また、請求項２記載の発明にあっては、請求項１の効果に加えて、連結部に軒樋排水溝に流れる雨水を伝わせて軒樋継手内に流下させる機能を持たせたので、軒樋排水溝を流れる雨水が軒樋継手内に流入する際に、上記雨水が連結部の板面を伝ってスムーズに軒樋継手内に流させることができるのである。

BACKGROUND OF THE INVENTION
The present invention relates to a connection structure for eaves.
[0002]
[Prior art]
Traditionally, in the eaves 1FIG.As shown in FIG. 2, the eaves wall front wall part 11 standing on the outdoor side, the eaves wall rear wall part 14 standing on the building side, the lower end of the eaves wall front wall part 11 and the eaves The main body is formed in a vertical U-shape with the eaves wall 15 which connects the lower end of the heel rear wall 14. Note that a front ear portion 16 is provided at the upper end of the eaves ridge front wall portion 11, and a rear ear portion 17 is provided at the upper end of the eaves ridge rear wall portion 14. Since the eaves wall front wall 11 is a part exposed to the outdoor side, the eaves wall front wall part 11 is a part that reveals the appearance of the eaves wall 1. The shape which contributes to the improvement of 1 external appearance is calculated | required. Moreover, although the eaves wall front wall part 11 exposed to the outdoor side is a part where rainwater falls, it is not preferable that the rainwater that falls on the eaves wall front wall part 11 is dripped down below the eaves wall 1. Thus, the eaves front wall portion 11 includes an upper eaves front wall portion 12 that forms the upper portion of the eaves front wall portion 11 and a lower eaves front wall portion 13 that forms the lower portion of the eaves front wall portion 11. An eaves drainage groove 18 that is recessed backward and downward is formed across the longitudinal direction of the eaves 1. Here, the upper eaves front wall portion 12 is a plate piece that is inclined so as to be located forward in the downward direction, and actively receives rainwater falling on the eaves front wall portion 11 and receives the rainwater from the eaves drainage groove 18. In addition, the lower eaves front wall 13 is a plate piece that is inclined so as to be located rearward as it is lower, so that it is difficult to receive rainwater that falls on the eaves front wall 11. In this way, the front eaves wall 11 is composed of the upper eaves front wall 12 and the lower eaves front wall 13, and the eaves eaves front wall 12 and the lower eaves front wall 13 are arranged between the eaves front wall 12 and the lower eaves front wall 13. By providing the eaves drainage groove 18, the eaves eaves drainage groove 18 extends in the longitudinal direction of the eaves eaves 1 and gives a uniform accent to the eaves eaves 1. At the same time, rainwater that falls on the front wall 11 of the eaves wall flows into the eaves drainage groove 18 to prevent the rainwater from flowing down the eaves wall 1.
[0003]
The eaves rod 1 having such a structure is connected by an eaves rod joint 2 'disposed between adjacent eave rods 1 with their longitudinal ends facing each other. That is, in the eaves joint 2 ', the longitudinal ends of the eaves 1 are connected to the left and right ends, respectively, and the eaves 1 are connected to each other through the eaves joint 2'. In this eaves joint 2 'FIG.There is something to show. The eaves joint 2 'wraps the outer surface of the eaves bowl 1 with its inner surface, that is, the eaves joint 1 fits along the outer surface of the eaves bowl 1 with the inner surface of the eaves joint 2'. The vertical cross-sectional shape is substantially the same as that of the eaves bowl 1 and is larger than the vertical cross section of the eaves bowl 1. In other words, the eaves joint 2 'includes a joint front wall portion 21 standing on the outdoor side, a joint rear wall portion 24 standing on the building side, and a lower end of the joint front wall portion 21. The main body is composed of a joint bottom wall portion 25 connecting the lower end of the joint rear wall portion 24. Here, in the joint front wall portion 21, in order to follow the outer surface of the eave ridge front wall portion 11 of the eave ridge 1, the vertical section is formed in a substantially arc shape so that the center portion in the vertical direction protrudes forward. In addition, the rainwater that has fallen on the upper part of the joint front wall portion 21 is poured into the eaves drainage groove 18 of the eaves joint 1 connected to the eaves joint 1 so that the eaves 1 connected to the eaves joint 2 ' A joint drain groove 28 that is continuous with the rod drain groove 18 is formed so as to be recessed from the outer surface of the joint front wall portion 21. A hook-shaped front ear engaging portion 26 that engages the front ear portion 16 is provided at the upper end of the joint front wall portion 21, and the rear ear portion 17 is engaged with the upper end of the joint rear wall portion 24. A hook-like rear ear engaging portion 27 is provided. In addition, on the inner surfaces of the joint rear wall portion 24 and the joint front wall portion 21, a restriction projection portion 4 that protrudes inward is provided. The restricting projection 4 regulates the insertion depth of the eaves rod 1 inserted from the left and right ends of the eaves joint 2 ′, and places an interval between the eaves 1 disposed opposite to the eaves joint 2 ′. In other words, a flow path is provided to allow rainwater flowing in the eaves drainage groove 18 of the eaves 1 to flow down into the eaves joint 2 '.
[0004]
As described above, when the eaves rod 1 is inserted from the left and right ends of the eaves rod joint 2 ′ and the pair of eaves rods 1 are connected to the eaves rod joint 2 ′,FIG.As shown in FIG. 4, the longitudinal ends, which are the insertion tips of the eaves rods 1 inserted from the left and right end portions of the eaves joint 2 ′, are brought into contact with the regulating projections 4 and in front of the eaves joint 2 ′. The ear engaging portion 26 and the rear ear engaging portion 27 engage the front ear portion 16 and the rear ear portion 17 of the eaves rod 1 to bring the outer surface of the eaves rod 1 into close contact with the inner surface of the eaves rod joint 2 '. Done in state. Here, when the joint front wall 21 of the eaves joint 2 ′ and the eaves front wall 11 of the eaves 1 are stacked, the joint drain groove 28 is fitted to the outside of the eaves drain 18. It has become. The fact that the joint drainage groove 28 fits into the eaves bowl drainage groove 18 means that the joint drainage groove 28 and the eaves bowl drainage groove 18 of the eaves bowl 1 are located at the left and right ends of the eaves bowl joint 2 '. However, the rainwater that has been received by the outer surface of the eaves wall front wall portion 11 of the eaves joint 2 ′ and has flowed into the joint drainage groove 28 from the left and right ends of the joint drainage groove 28. It will flow into. And the rainwater which flows into the eaves drainage groove 18 including the rainwater which flowed in from the said joint drainage groove 28 is the eaves joint 2 from the longitudinal direction edge part of the eaves drainage groove 18 located inside the eaves joint 2 '. It will flow into the inside of '. As described above, the rainwater that has fallen on the joint front wall portion 21 of the eaves joint 2 ′ or the eaves joint front wall portion 11 of the eaves joint 1 passes through the joint drainage groove 28 and the eaves joint drainage groove 18. The rainwater can be prevented from dripping from the eaves joint 2 ′ or eaves 1.
[0005]
[Problems to be solved by the invention]
However, fitting the joint drainage groove 28 to the eaves drainage groove 18 means closing the opening on the front surface of the eaves drainage groove 18 with the joint drainage groove 28, that is, inside the eaves joint 2 ′. Since the eaves drainage groove 18 positioned in a tubular shape has a vertical cross section, the eaves drainage groove 18 in the above portion is liable to be clogged with dirt such as dead leaves, so that rainwater flows into the eaves joint 2 '. The problem of being disturbed arises. Further, in order to make the flow path of the eaves drainage groove 18 located inside the eaves eaves joint 2 ′ as large as possible, the recessed amount of the joint drainage groove 28 is larger than the recessed amount of the eaves drainage groove 18. Since it is formed shallowly, the appearance that the continuous eaves drainage groove 18 and the joint drainage groove 28 appear is a problem that some discomfort appears due to the difference in the amount of depression of the two grooves. was there.
