Description

【０００１】
【発明の属する技術分野】
本発明は、道路や鉄道の橋梁や盛土の端又は車線分離帯等に設けられた擁壁上に設置される防音壁、投物防止柵等のフエンスに関するものである。
【０００２】
【従来の技術】
従来、道路や鉄道の橋梁や盛土の擁壁上にフエンスを施工する場合、擁壁上に支柱を立設し、その支柱側面に面材を当接保持しつつ、支柱と面材とをボルト止めしている。あるいは、擁壁上に溝付き支柱を立設し、その溝に支柱上方から面材を差し込んで組み立てている（例えば特許文献１参照）。

【０００４】
【発明が解決しようとする課題】
しかし、かかる従来のフエンスでは、先の施工例では面材のボルト孔と支柱のボルト孔とを合わせるのが困難であり、後の施工例では支柱の上端より上方から面材を高く持ち上げて垂直に支持しながらの施工に手間がかかるうえに、支柱の溝の上端と面材の他端とを位置合わせするのが困難であるという問題点がある。また、これら従来のフエンスでは例えば面材の清掃などのメンテナンスの際は、特に擁壁の外側に足場を組むなどかなりな手間がかかるという欠点があった。
【０００５】
本発明は、かかる従来の課題に鑑みてなされたものであり、まず施工が簡単であり、しかも点検、修理、クリーニングなどメンテナンスも簡単に行える施工性のよいフエンス及びフエンスの施工方法を提供せんとするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するため、本発明は以下のような構成としている。すなわち、本発明に係る施工性のよいフエンスは、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスであって、擁壁上に支柱が立設されるとともに支柱間に面材が支持されてなり、その面材が自身で、または面材が支柱とともに擁壁の内側に傾倒可能となされ、支柱下部の水平方向に支軸が突設されるとともに、その支軸の後方に面材支持材が支柱の高さ方向に沿って形成され、その面材支持材の上部にはボルト孔が穿設され、あるいはボルトが突設される等固定手段が設けられ、面材には下部左右に逆Ｕ字溝を有する軸受けが形成され、面材上方にボルト孔が穿設され、面材下部の軸受けが支柱下部の支軸に嵌合されて面材が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた面材が支柱後方の面材支持材に沿わされ、面材支持材の固定手段と面材のボルト孔の部分においてボルト止めされるようになされたことを特徴とするものである。
【０００７】
本発明によれば、支柱と面材の組み立てが擁壁の内側、すなわち擁壁の一方側のみで行え、作業性がよくて擁壁の外側から作業する必要がないので安全であるとともに、フエンス設置後においても面材の点検、修理、クリーニングや破損時の取り替え等、メンテナンスに際してもフエンスを擁壁の内側に傾倒させるだけで容易に行える。本発明においては、面材が自身で、または面材が支柱とともに擁壁の内側に傾倒可能となされており、擁壁の内側のみに傾倒可能となされていてもよいし、擁壁の内側のみならず外側にも傾倒可能となされていてもよい。
【０００８】
本発明において、支柱下部の水平方向に支軸が突設されるとともに、その支軸の後方に面材支持材が支柱の高さ方向に沿って形成され、その面材支持材の上部にはボルト孔が穿設され、あるいはボルトが突設される等固定手段が設けられ、面材には下部左右に逆Ｕ字溝を有する軸受けが形成され、面材上方にボルト孔が穿設され、面材下部の軸受けが支柱下部の支軸に嵌合されて面材が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた面材が支柱後方の面材支持材に沿わされ、面材支持材の固定手段と面材のボルト孔の部分においてボルト止めされるようになされているものである。
【０００９】
かようにすれば、面材下部の軸受けを支柱下部の支軸に嵌合させるだけで、擁壁の内側から、面材を支柱に取付けることができ、又面材を支柱に固定するに際しても、傾倒状態から面材を立ち起こし、支柱後方の面材支持材に沿わせるだけで、面材支持材のボルト孔あるいは突設ボルト等の固定手段と面材のボルト孔とを楽に一致させることができ、簡単なボルト止め作業によるだけで面材を支柱に、擁壁の内側から、強固に固定することができ、施工の作業性がよく、かつ安全に行える。
【００１２】
また本発明は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスであって、擁壁上に支柱が立設されるとともに支柱間に面材が支持されてなり、その面材が自身で、または面材が支柱とともに擁壁の内側に傾倒可能となされ、擁壁上に支柱受け材が取着され、その支柱受け材に支柱下部が軸着されて支柱が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた前記支柱の支柱下部と支柱受け材とがボルトで固定されるとともに、前記支柱に面材が取付けられるようになされ、擁壁上に支柱受け材が取着され、その支柱受け材に支柱下部が軸着されて支柱が擁壁の内側に傾倒可能となされ、支柱の側壁に高さ方向に沿って面材用溝が形成され、支柱が擁壁の内側に傾倒された状態で面材用溝に面材が挿入され、支柱が面材ごと立ち起こされるようになされたものである。
【００１３】
かようにすれば、支柱を擁壁の内側に傾倒した状態で、面材を支柱に取付けることができ、従来のように面材を高く持ち上げて作業するという不安定かつ不安全な作業を経ず、面材を取付けた後、擁壁の内側から、面材ごと支柱を立ち起こして支柱下部と支柱受け材とをボルトで固定するだけで施工でき、又、支柱の面材用溝に面材の両端部を挿入するだけで、面材を支柱に取付けることができるので、面材の取付作業が早くかつ容易になる。
【００１４】
また本発明は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスであって、擁壁上に支柱が立設されるとともに支柱間に面材が支持されてなり、その面材が自身で、または面材が支柱とともに擁壁の内側に傾倒可能となされ、擁壁上に支柱および面材支持フレームが取着され、面材は周囲が面材枠に保持されるとともに、その面材枠の下枠が前記面材支持フレームに脱着可能に軸着されて、面材が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた面材の面材枠が支柱に固定されるようになされているものである。
【００１５】
かようにすれば、上記した効果に加えて、面材枠により面材を破損等から保護できる。これは、面材が比較的破損しやすいポリカーボネートやアクリル樹脂等の合成樹脂板や強化ガラス等からなる場合に効果的である。
【００１６】
さらに本発明は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスであって、擁壁上に支柱が立設されるとともに支柱間に面材が支持されてなり、その面材が自身で、または面材が支柱とともに擁壁の内側に傾倒可能となされ、擁壁上に立設された支柱に、アームが擁壁の内側に傾倒可能に軸着されると共に、前記アームが傾倒状態において、隣り合う一対の前記アームの先端部間に、面材枠に保持された面材が回動可能に軸着され、面材ごと傾倒状態から立ち起こされた前記アームが支柱に固定されるようになされているものである。
【００１７】
かようにすれば、面材をアームごと立ち起こし、支柱に固定するのみで設置作業が完了することから、極めて迅速にフエンスを設置することができ、交通規制等を行う時間を短縮し、円滑な交通を妨げる恐れが少なくなる。
【００２１】
次に本発明に係るフエンスの施工方法は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスの施工方法であって、擁壁上に立設した支柱間に擁壁の内側に傾倒可能に面材を取付け、支柱下部の水平方向に支軸が突設されるとともに、その支軸の後方に面材支持材が支柱の高さ方向に沿って形成され、その面材支持材の上部にはボルト孔が穿設され、あるいはボルトが突設される等固定手段が設けられ、面材には下部左右に逆Ｕ字溝を有する軸受けが形成され、面材上方にボルト孔が穿設され、面材下部の軸受けが支柱下部の支軸に嵌合されて面材が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた面材が支柱後方の面材支持材に沿わされ、面材支持材の固定手段と面材のボルト孔の部分においてボルト止めされて、面材を傾倒状態から立ち起こして支柱に固定することを特徴とするものであり、又他のフエンスの施工方法は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスの施工方法であって、擁壁上に立設した支柱間に擁壁の内側に傾倒可能に面材を取付け、擁壁上に支柱および面材支持フレームが取着され、面材は周囲が面材枠に保持されるとともに、その面材枠の下枠が前記面材支持フレームに脱着可能に軸着されて、面材が擁壁の内側に傾倒可能となされ、傾倒状態から立ち起こされた面材の面材枠が支柱に固定され、前記支柱間に面材を取付けることを特徴とするものであり、さらに他のフエンスの施工方法は、橋梁や盛土の端側又は車線分離帯等の擁壁上に設置されるフエンスの施工方法であって、擁壁上に立設した支柱間に擁壁の内側に傾倒可能に面材を取付け、擁壁上に立設された支柱に、アームが擁壁の内側に傾倒可能に軸着されると共に、前記アームが傾倒状態において、隣り合う一対の前記アームの先端部間に、面材枠に保持された面材が回動可能に軸着され、面材ごと傾倒状態から立ち起こされた前記アームが支柱に固定され、面材を傾倒状態から立ち起こして支柱に固定することを特徴とするものである。
【００２２】
これらの発明によれば、擁壁の内側からフエンスを施工できるので、作業性がよくて擁壁の外側から作業する必要がないので安全であるとともに、フエンス設置後においても面材の点検、修理、クリーニングや破損時の取り替え等、メンテナンスに際してもフエンスを擁壁の内側に傾倒させるだけで容易に行える。これら発明においては、先ず面材又は支柱を擁壁の内側に傾倒可能とするが、擁壁の内側のみに傾倒可能としてもよいし、擁壁の内側のみならず外側にも傾倒可能としてもよい。
【００２３】
又本発明に係る他のフエンスの施工方法は、橋梁や盛土の端側又は車線分離帯等の擁壁上に、複数のフエンス体を上下方向又は長手方向若しくは並列に配置して設置するフエンスの施工方法であって、前記複数のフエンス体の少なくとも一つを上記したフエンスの施工方法により施工することを特徴とするものである。。
【００２４】
この発明によれば、上記したフエンスの施工方法により施工されるフエンスについては、上記と同様の効果を期待することができるとともに、従来の施工方法では危険である、例えば上下方向に複数段設置する場合等、上方での高所作業が必要な場所、又は長時間の交通規制が困難な場所などにおいても、作業性のよい施工が可能であるから、施工に伴う危険を低減することができる。
【００２５】
尚、複数のフェンス体を備えた上記の各発明において、フェンス体とは、少なくとも面材を備えたものであって、該面材を支持する支柱は、各フェンス体において共用されたものであってもよいし、各フェンス体において、それぞれ別個に設けられたものであってもよい。
【００２６】
【発明の実施の形態】
本発明に係わる実施の形態について、図面に基づき以下に具体的に説明する。図１及び図２は、本発明に係わる実施の一形態を示すもので、図１は取付状態を示す説明図、図２はその側面図である。まず図１において１は支柱であるが、この支柱１は型鋼、型材、管体等の適宜材料からなり、支柱１の下部に支軸１１が水平方向に突設され、それら支軸１１の後方には、Ｔ字状の断面を呈するように、面材支持材１２が支柱１の高さ方向に沿って形成され、面材支持材１２上部にボルト孔１３が穿設されている。また、支柱１の下端部にはアンカープレート１４が固定され、このアンカープレート１４を介して支柱１が擁壁３上に立設固定されている。
【００２７】
図１において２は面材である。この面材２の下端部左右には逆Ｕ字溝２２を有する軸受け２１が形成されるとともに、面材２の上方の左右にはボルト孔２３が穿設されている。尚、面材２は任意の材料から形成され、例えばアルミニウムや鉄鋼、ステンレス等の金属製フレームにポリカーボネートやアクリル樹脂等の合成樹脂板や強化ガラス等からなる透明なパネルがはめ込まれたものであってもよく、更には吸音性能や遮音性能を具備した防音パネル等のパネルユニット、防風、防雪、その他、例えば電波吸収機能といった多様な機能を伴う用途のものを使用してもよい。
【００２８】
施工方法は、前記図１に図２を加えて説明すると、図２（ａ）に示される如く、擁壁３の内側から、面材２下部の軸受け２１を支柱下部の支軸１１に嵌合した後、傾倒状態の面材２を立ち起こして、同図（ｂ）の如く支柱１後方の面材支持材１２に沿わし、面材支持材１２のボルト孔１３と面材２のボルト孔２３とをボルト止めすればよい。
【００２９】
かかるフエンスは、支柱１と面材２の組み立てが擁壁３の内側にて行うことができ、擁壁の外側に基礎等を設置する必要もなく作業性は向上される。また擁壁の外側から作業する必要がないので安全である。更にフエンス設置後においても面材の点検、修理、クリーニングや破損時の取り替え等、メンテナンスに際してもフエンスを擁壁の内側に傾倒させるだけで容易に行うことができ、メンテナンスの終了後も面材２を元の位置に戻してボルト止めすればよく、作業性、安全性は格段に向上される。
【００３０】
更に面材２下部の軸受け２１を支柱１下部の支軸１１に嵌合させるだけで面材２を支柱１に取付けることができ、さらに傾倒状態の面材２を立ち起こして面材支持材１２に沿わせるだけで面材支持材１２のボルト孔１３あるいは突設ボルト等の固定手段と面材２のボルト孔２３とを楽に一致させることができ、簡単なボルト止め作業によるだけで面材２が支柱１に強固に固定され、施工の作業性がよく、かつ安全に行える。
【００３１】
図３及び図４は、本発明に係る参考例を示すもので、図３は面材の取付ける状態を示す説明図、図４はその側面図である。まず図３に示す如く、擁壁３上に支柱受け材１５が取着され、その支柱受け材１５に支柱１下部が軸着されて、支柱１が擁壁３の内側に傾倒可能となされている。ここで支柱受け材１５は上方に開口され、擁壁の内側方向には外側に湾曲する軸着部１５１が設けられると共に、外側方向には支持部１５２が設けられ、且つ軸着部１５１の高さより支持部１５２の高さを高くし、支柱受け材１５への支柱１の係止時に支柱１や取付用のボルトが落下するのを防止し、更には係止された支柱１が擁壁の外側方向に倒れるのを防止している。
【００３２】
支柱１は図４に示す如く、下端部に内側に湾曲する断面円弧状の軸着部１８が設けられ、軸着部１８が支柱受け材１５の軸着部１５１の内面に当接するように嵌合されることで、支柱１は支柱受け材１５に軸着される。軸着された支柱１は、傾倒状態から立ち起こされて支柱受け材１５と支柱１下部とがボルト（図示せず）で固定された後、支柱１に面材２が取付けられる。本形態においては、面材２は主面材２ａ及び補助面材２ｂとからなり、まず主面材２ａのボルト孔２３を予め支柱１から突設させたボルト１９に挿通させて仮り止めし、更に補助面材２ｂのボルト孔２３にボルト１９を挿通させて押さえ部材２４を取り付けてボルト１９にナット（図示せず）を螺着により固定する。
【００３３】
本形態においては、主面材２ａは透明な面材２ａ１を枠材２ａ２にはめ込んだものであり、透光性や透視性を有するものである。補助面材２ｂは透明な面材であってもよく、また金属線を所定の間隔で縦横に張り巡らせたものであってもよい。補助面材２ｂを取り付けておけば、透光性や透視性を損なうことなく擁壁の内側方向からの投物等により主面材２ａが破損するのを防止できる。
【００３４】
かかるフエンスは、支柱１と面材２の組み立てが擁壁３の内側にて行うことができ、擁壁の外側に基礎等を設置する必要もなく作業性は向上される。また擁壁の外側から作業する必要がないので安全である。更に基本的には支柱受け材１５、支柱１及び面材２といった少ない点数の部材であり、容易且つ安全にフエンスを施工することが可能となる。
【００３５】
図５及び図６は、本発明に係わる他の実施の形態を示すもので、図５は面材の取付状態を示す説明図、図６はその側面図である。まず図５において、支柱１は下端のアンカープレート１４が擁壁３上に取着された支柱受け材である台座１５にヒンジ１６により軸着され、支柱１がヒンジ１６の部分で擁壁３の内側に傾倒可能となされている。また支柱１の側壁には高さ方向に沿って面材用溝１７が形成され、支柱１が擁壁３の内側に傾倒された状態で面材用溝１７に面材２が挿入固定された後、支柱１が面材２ごと立ち起こされ〔図６（ａ）→（ｂ）で示す〕、ヒンジ１６と反対側の台座１５と支柱１下端のアンカープレート１４がアンカーボルトにて固定されるようになされている。そして、相隣り合う支柱１はそれらの上端部でボルトによって接続固定されている。
【００３６】
かかるフエンスは、支柱１を擁壁３の内側に傾倒した状態で支柱１の面材用溝１７に面材２を挿入固定できるので、従来のように面材２を高く持ち上げて作業するという不安定且つ不安全な工程を経ず、面材２の挿入後支柱１を立ち起こして台座１５と支柱１下部とをボルトで固定するだけで施工できるため、施工作業も容易で安全に行える。
【００３７】
図７及び図８は、本発明に係わる更に他の実施の形態を示すもので、図７は面材の建て込みの状態を示す説明図、図８はその側面図である。まず図７において、擁壁３上に外側に縦壁を立設した受けフレーム１５及び支柱１ａが設けられ、更に支柱１ａの擁壁の内側方向に面材支持フレーム２５が取り付けられる。受けフレーム１５が設けられることで、ボルトの取り付け時等において、部材が擁壁３の外側に落下するのを防止できる。この面材支持フレーム２５に面材２の下枠２６が軸着されて、面材２が擁壁３の内側に傾倒可能となされ、面材２が傾倒状態から立ち起こされて断面Ｔ字状の支柱１ａの側面に当接され、ボルト・ナット等により面材２が支柱１に固定されることでフエンスが設置される。
【００３８】
図８に示す如く、面材２は面材支持フレーム２５及び下枠２６により立ち起こされるが、その状態の詳細を示すのが同図（ａ）〜（ｃ）である。（ａ）に示す如く、下枠２６には断面円弧状の取付部２６１が設けられ、面材支持フレーム２５にも断面円弧状の取付部２５１が設けられている。次に、（ｂ）に示す如く下枠２６の取付部２６１が取付部２５１の外面に当接され、面材支持フレーム２５と下枠２６とが係合されて軸着されることで、面材２は擁壁３の内側に傾倒可能となされ、また面材２を立ち起こすことができる。最後に（ｃ）に示す如く、立ち起こされた面材２は支柱１に当接されてボルト・ナット等により固定支持されることでフエンスは設置される。
【００３９】
かかるフエンスは、フエンスの形成に係わる作業を全て擁壁３の内側にて行うことができ、擁壁３の外側に基礎等を設置する必要もなく作業性は向上される。また擁壁３の外側から作業する必要がないので安全である。更には面材２上端までの高さを必要としない支柱１を用いることでフエンスを軽量なものとでき、擁壁３にかかる重量の負担を軽減することができる。
【００４０】
図９〜図１２は、本発明に係わるフエンスの施工方法の、実施の一形態を示すもので、図９は支柱の建て込みの状態を示す説明図、図１０は面材の建て込みを示す説明図、図１１及び図１２は更に積み重ねられる面材の建て込みを示す説明図である。まず図９において、ボルト孔１３が穿設された面材支持材１２を有する支柱１ｂのアンカープレート１４と、受けフレーム１５とが、擁壁３に穿設されたアンカーナット３１及びアンカーボルト３２によって擁壁上に固定される。
【００４１】
次に図１０において、支柱１ｂの面材支持材１２前面の、アンカープレート１４上に面材支持フレーム２５ａがビス、リベット等により取り付けられる。ここで面材支持フレーム２５ａの長さは面材支持材１２の幅と略同一とされているが、更に長いものであってもよい。面材２に設けられた下枠２６は、面材支持フレーム２６ａと、図８に示した如き構造にて係合されて軸着されることで、面材２は、擁壁３の内側に傾倒可能となされるとともに、立ち起こされて立設される。立設された面材２は、ボルト孔２３及び支柱１のボルト孔１３に挿通されたボルトＢにより面材支持材１２に固定される。ここで支柱１ｂのボルト孔１３は下方に位置するものが使われ、それより上方の面材支持材１２及びボルト孔１３は、上方に積み重ねられる面材２を支持するのに用いられる。
【００４２】
更に、図１１において面材２の上端に、面材支持フレーム２５ｂが取り付けられる。面材支持フレーム２５ｂは、本図の如く面材２を立ち起こした後に別部材を取り付けても、立ち起こす前に取り付けておいてもよく、また面材２に一体に設けておいてもよい。面材２が立ち起こされた後に生じる面材２の下端と擁壁３との隙間Ｓについては騒音が漏洩する恐れがあり、カバー材を取り付けたり、面材２の下端の形状を変更する等により閉塞しておいてもよい。
【００４３】
面材２上端に取り付けられた面材支持フレーム２５ｂに、図１２に示す如く面材２が取り付けられる。下端に下枠２６ｂが取り付けられた面材２は、その下枠２６ｂが面材支持フレーム２５ｂに軸着されて下方の面材２と係合される。更に上方の面材２は立ち起こされて、ボルト孔２３及びボルト孔１３にボルトＢが挿通されナット等に螺着されることで、上方の面材２も支柱１及び下方の面材２に固定され、面材２が複数段積み重ねられたフエンスが形成される。
【００４４】
かかる施工方法によりフエンスを形成することで、前述の通り少なくとも１段の面材については上述の通り安全で煩雑な手間を軽減して施工ができると共に、従来の施工方法では危険である、例えば複数段の上方で高所作業が必要な場所、長時間の交通規制が困難な場所などにおいても、かかる施工方法は作業性のよい施工が可能であるから、施工に伴う危険を低減することができる。
【００４５】
また、本形態においては、立設した支柱１ｂに、面材支持フレーム２５ａ、２５ｂに面材２の下枠２６ａ、２６ｂを、軸着、係合して面材２を立ち起こし、ボルト孔２３によってボルト止めすることでフエンスが形成可能であるから、施工は極めて迅速に行われ、施工に伴う交通規制の時間等の制約を低減できる。また、面材２を複数段積み重ねる場合、主としてかかる施工方法を用いて施工を行うことで、安全性や迅速性といった、施工における利点は更に大きいものとなされる。更に、上段の面材２は下端の面材２と軸着されているから、立ち起こす際の労力が少なくて済み、人力のみで施工可能な面材２の重量を、面材２を持ち上げる必要のある場合よりはるかに大きくできる。
【００４６】
図１３及び図１４は、本発明に係わるフエンスの施工方法の、他の実施の形態を示すもので、図１３は最初の面材の取り付けを示す説明図、図１４は施工の手順を示す側面図である。本実施形態に示すフエンスは、本出願人による特開平９−２０９３２１号公報に記載の如きもので、防護柵と投物防止用フエンスとが一体になされたものである。図１３において、支柱１ｃには、衝突した車両の転落等を防止する３本の横梁Ｙが取り付けられ、その外側に面材２が挿入可能な面材用溝１７が設けられている。本実施形態において、面材２は投物を防止しつつ風荷重を軽減する金網状のものであるが、透明、不透明を問わず板状のものを用いてもよい。まず、かかる面材２が支柱１ｃに設けられた面材用溝１７に挿入される。
【００４７】
続いて図１４において、（イ）に示す如く面材用溝１７に面材２は挿入されるが、挿入された面材２は、隙間にバネを打ち込む等の方法で支柱１ｃに固定される。次に（ロ）に示す如く、下段の面材２の上端に面材支持フレーム２５が取り付けられ、その面材支持フレーム２５に、上段の面材２に取り付けられた下枠２６が軸着され係合され、上段の面材２は擁壁３の内側に傾倒可能とされる。面材支持フレーム２５、下枠２６は、それぞれの面材２に予め取り付けられるか、又は一体に設けられているものであってもよい。更に（ハ）において、下段の面材２に軸着され係合された上段の面材２が傾倒状態から立ち起こされて、ボルト孔２３及びボルト孔１３に挿通されたボルトＢにより支柱１ｃの面材支持材１２に固定される。
【００４８】
かかる方法によりフエンスを施工することで、前述の通り少なくとも上段の面材については上述の通り安全で煩雑な手間を軽減して施工ができ、施工に伴う危険を低減することができると共に、面材支持部１２のボルト孔１３の高さまで届けば施工が可能であるから、面材２が複数段積み上げられた場合でも作業に要する高さを低くして更に施工性を向上させることができる。
【００４９】
図１５及び図１６は、本発明に係わる施工性のよいフエンスの、更に他の実施形態を示すもので、図１５は面材の建て込みの状態を示す説明図、図１６はその側面図である。まず図１５において、擁壁３上に立設された支柱１ｂに擁壁３の内側に傾倒可能なアーム２７が軸着される。隣り合う一対のアーム２７間には面材枠２ａ２に保持された面材２ａ１がその面材枠２ａ２のコーナー部分においてアーム２７の先端部分に回動可能に軸着されている。
【００５０】
このアーム２７が立ち起こされて後、支柱１ｂに固定支持される状態を示すのが図１６であり、まず同図（ａ）に示す如く、擁壁３の内側にアーム２７を傾倒させた状態で面材２をアーム２７に取り付ける。アーム２７はまず面材２に取り付けておいてから、設置時に支柱１ｂに取り付けてもよい。支柱１ｂにアーム２７を取り付け、アーム２７に面材２を取り付けた状態で、同図（ｂ）及び（ｃ）に示される如く、アーム２７を立ち起こして面材２を支柱１ｂに当接させ、ボルト・ナット等により面材２を支柱１ｂに固定支持することでフエンスは形成される。
【００５１】
かかるフエンスは、フエンスの形成に係わる作業を全て擁壁３の内側にて行うことができ、擁壁３の外側に基礎等を設置する必要もなく作業性は向上される。また擁壁３の外側から作業する必要がないので安全である。更には、アーム２７に支柱１ｂ及び面材２を取り付け、面材２をアーム２７ごと立ち上げるのみで設置が完了することから、極めて迅速にフエンスを設置することができ交通規制等を行う時間を低減し、円滑な交通を妨げる恐れが小さくできる。
【００５２】
図１７及び図１８は、本発明に係わる更に他の参考例を示すもので、図１７は面材の建て込みの状態を示す説明図、図１８はその上面図である。まず図１７において、擁壁３上に立設された支柱１の内、支柱１Ａに面材２ａ１を保持する面材枠２ａ２の一方の縦辺が係合可能に軸着され、面材２が支柱１Ａを軸として水平方向に開閉可能となされている。支柱１Ｂ及び１Ｃ間にも同様の方法で面材２が取り付けられ、これらが設置された場合には一連のフエンスとなるものである。
【００５３】
