Description

【０００１】
【発明の属する技術分野】
本発明は、特に、山間部に敷設されている鉄道、自動車道に沿って既に設置されている線路や道路内に人や小動物が侵入するのを防止するための防獣フェンスの防獣性能を上げるためのフェンス体およびそれを利用した防獣フェンスに関する。
【０００２】
【従来の技術】
従来より、山間部を走る高速道路や鉄道路線に対しては、安全上、その他の観点から道路や路線内にキツネ，タヌキ，イノシシ等の獣類、或は、人が侵入することがないように、ネット状に編成した金網を使用したいわゆる防獣フェンスが設置されている。
【０００３】
しかし、ネット状に編成した金網タイプのフェンスは、矩形状などのフレームを作り、このフレームに金網を張設してフェンス体に形成し、これを支柱に取付けているため、正面矩形状のフレーム（枠）を不可欠とする構造であり、従って、設置場所に凹凸が多くある山間部では、フェンス体と地上面の間に大小様々な隙間が生じ、この隙間が獣の侵入防止に役立たないことが指摘されている。また、このような隙間がなくても、金網タイプのフェンスでは、その網の目に手，爪を掛けて小動物がフェンスを乗り超えることが知られており、この点でも問題である。
【０００４】
また、金網タイプのフェンスは、金網自体がその面に対するせん断方向の外力に対して変形し易いため、この方向での力を受けると、フレームを含みフェンス全体が変形したり、金網がフレームから外れてしまうことがあり、防獣フェンスとしての機能を損なってしまうという問題もある。特に、積雪地帯では、フェンスの周囲に積もった雪による圧力が当該フェンスに様々な態様でかかるため、雪が融けると上記フェンスの変形や損壊が露呈し、毎年その修復に追われているというのが現状である。
【０００５】
この点は、比較的人の出入がある山間地の鉄道や自動車道に設けられた金網タイプのフェンスについても、出入りする人の悪戯などにより、同様の問題が生じている。
【０００６】
従来、上記のような問題点に鑑み、フェンスを二重に設置したり、耐雪用にフレームを強度の大きな材料で形成し、このフレームに、番手の太い線で形成した金網を取付けてフェンスを形成するなどの対策が採られているが、このような対策ではコストが高くなるのみならず、前記問題の根本的な解決を図ることはできていない。
【０００７】
上記のような従来の防獣用のフェンスの現状に鑑み、本発明の出願人はフェンスを二重に設ける必要が無く、また、設置場所における地表の凹凸の有無に拘わらずフェンスと地上の間に隙間が生じないだけではなく、小動物がフェンスの下に穴を掘っても通り抜けることができないフレームレスタイプの防獣フェンスを形成するためのフェンス体を提案せんとするものである。（例えば、特許文献１。）。

【発明が解決しようとする課題】
本発明は上記のような従来の防獣用フェンスの現状に鑑み、フェンスを二重に設ける必要がなく、また、設置場所における地表の凹凸の有無に拘わらずフェンスと地上の間に隙間が生じないだけではなく、小動物がフェンスの下に穴を堀っても通り抜けることができず、更に、小動物であってもフェンスの隙間から抜けられないことは勿論、手や爪を掛けてもフェンスに登ることも不可能にし、加えて、積雪地帯に設けても雪圧により変形することがないフレームレスタイプの防獣フェンスを形成するためのフェンス体を提供することを課題とするものである。
【００１０】
【課題を解決するための手段】
そこで、請求項１記載の本発明では、正面幅が５００〜３０００ｍｍ、高さが１０００〜１８００ｍｍのフェンス体であって、このフェンス体は、４〜６ｍｍφの太さで長さが１０００〜１８００ｍｍの鋼棒を５０〜６０ｍｍ間隔で縦向きに平行にして前記正面幅をなすように並べた縦メンバと、４〜１０ｍｍφの太さで長さが前記正面幅と略同長の鋼棒による横メンバの２本乃至３本を幅が５０〜６０ｍｍをなすように横向きに平行に並べる横メンバの組とにより、該複数の横メンバの組を前記縦メンバの上に、当該縦メンバの上端近くから４００ｍｍ〜５００ｍｍの間隔を持たせて配置し、かかる横メンバの組と縦メンバとによりフェンス体をフレームレス形成とすると共に、配置した前記横メンバの組の最下位のものより下方に２００ｍｍ〜７０ｍｍの間隔で前記横メンバと同じ鋼棒による副横メンバを縦メンバの上に配置し、各縦メンバと各横メンバの交叉部を溶接により接合することにより、最下位の横メンバの組より下方に位置する縦メンバを櫛歯状とした櫛歯状部とし、同櫛歯状部は、地中に突刺して埋設されるべく構成したことを特徴とする防獣フェンス用のフェンス体を提供せんとするものである。

【００１６】
【発明の実施の形態】
次に、本発明フェンス体の実施の形態について、例を挙げて図に拠り説明する。図１は従来の防獣用フェンスを形成するフェンス体の一例の正面図、図２は図１のフェンス体をフェンスの一例として設置した例の部分正面図、図３は本発明を適用するフェンス体の一例の正面図、図４は図３のフェンス体を設置した例の部分正面図、図５は図２又は図４の側面図、図６は図３のフェンス体に安全キャップを設けた本発明フェンス体の一例の側断面図、図７は補助フェンス体の一例の正面図、図８は図７の補助フェンス体の使用例の正面図である。
【００１７】
図１において、Ｆｂは正面から見た外形が長方形状をなすフェンス体で、ここでは次のように構成されている。即ち、１は前記フェンス体Ｆｂの縦メンバで、図１の例では４ｍｍφの太さで長さが１５５０ｍｍの鋼棒を、ほぼ５０ｍｍ間隔で縦向きに平行に並べ、その全体が、このフェンス体Ｆｂの正面幅である、例えば１５００〜２０００ｍｍ程度になるように配置される。実際には、後述する支柱の芯々間距離が２０００ｍｍの設計の場合、フェンス体Ｆｂの幅は２１００ｍｍ程度に形成する。このフェンス体Ｆｂの正面幅は、使用する縦メンバ１の数量により、任意の幅に形成することができる。具体的には、設置場所で凹凸状況や傾斜状況により設置される支柱間の距離の種類に見合う長さ、或は、運搬等の便宜を考えると、５００〜３０００ｍｍ程度であることが実用的である。
【００１８】
２は、上記において縦向きに平行に並べられることにより全体が１５００〜２０００ｍｍ程度の幅に配置された縦メンバ１に対して、その上面に、横向きに配置した横メンバで、ここでは太さが６ｍｍφ、長さが、並べた前記縦メンバ１の全体の幅と同等乃至は少し長い１５００余〜２０００余ｍｍの鋼棒の２本を略５０ｍｍの間隔で平行に並べたものを一組の横メンバ（以下、横メンバの組２という）とし、前記で並べた縦メンバ１の上に、ここでは縦メンバ１の上端部から順に約４００ｍｍのピッチで４組の横メンバの組２を配置し、縦メンバ１と横メンバの組２を、それらの各交点において、溶接により固着することにより、図１に示す正面形態のフレームレスのフェンス体Ｆｂに形成されている。
【００１９】
ここで、横メンバの組２は、４〜１０ｍｍφの太さの鋼棒の中から、設置場所の環境等を考慮して使用する鋼棒の太さを選択するが、通常は６〜８ｍｍφの中から選択する。また、横メンバの組２は、３本の鋼棒で形成してもよく、また各横メンバの組２の縦メンバ１の上での配置間隔も３００ｍｍ以上、例えば５００ｍｍ程度とすることもある。上記例において配置間隔を５００ｍｍとした場合には、横メンバの組２は縦メンバの上に３組配置されることになる。上記フェンスにおいて、横メンバの組２は縦メンバ１と同等又は太い鋼棒を使い、しかも、それを２〜３本を１組とする使用態様とするのは、フェンス体Ｆｂをフレームレス形式とし、フレームレスであってもフェンス体全体の強度を上げると共に、縦メンバ１の上端部の横メンバの組２に、従来フェンスの胴縁に代わる機能を持たせるためである。
【００２０】
図１に示すフェンス体Ｆｂは、太さが４〜６ｍｍφの縦メンバ１と４〜１０ｍｍφの横メンバの組２により形成されていると共に、両メンバ１，２により形成される縦長の窓（スリット）３は、芯々間の大きさで約５０ｍｍラ４００ｍｍの大きさであるから、小動物がこのスリット３から抜けられないことは勿論、このスリット３における縦メンバ１のスパンは、４〜６ｍｍφの鋼棒で４００ｍｍであるから、人手によっても曲げることは殆んど不可能乃至は困難、つまり、スリット３の横幅を拡開することは困難であり、従って、小動物がこれを変形させて反対側に抜け出すことは事実上あり得ず、また、人であってもスリット３を変形させて通り抜けることは勿論不可能である。
【００２１】
また、上記のフレームレスのフェンス体Ｆｂは、各スリット３の長さが、この例では４００ｍｍであるから、下方の横メンバの組２に小動物が手や爪を引掛けても、次の横メンバの組２に手や爪が届かず、従って、このフェンス体を小動物がよじ登ることは出来ない。
【００２２】
更に、上記フェンス体Ｆｂの下端は、フレームレスゆえに、その横メンバの組２の上記の取付態様によって、最下位の横メンバの組２より下方に位置する縦メンバ１が、いわば櫛歯状に、図の例では略１３０ｍｍほど下向きに突出しているので、山間地等の地表に凹凸がある場所では、この櫛歯状部４を地中に突刺すように設置すれば、前記地表の凹凸に関係なくフェンスの下端に隙間が形成されることはなく、しかも、この櫛歯状部４が地中に埋設されることにより、小動物がフェンス体Ｆｂの下に穴を掘っても、前記櫛歯状部４に阻止されるので、そのような穴からの通り抜けも防ぐこともできる。
【００２３】
上記のように形成されるフェンス体Ｆｂは、例えば山間部に通された鉄道や自動車道に沿って、例えば防獣フェンスＰＦとして設置されるので、この点について図２，図５により説明する。
【００２４】
まず、図１のフェンス体Ｆｂを、その一枚の幅を、支柱間隔の単位として複数の支柱５を地上Ｇに立設する。この支柱５自体の構造やその立設基礎６は、従来フェンスの場合と略同様である。防獣フェンスは、立設した各支柱５の路面（鉄道又は道路）側を前面にし、この前面に、前記フェンス体Ｆｂを、その横メンバの組２を外面（縦メンバ１を支柱５の前面に対向させる）に向けて、各フェンス体Ｆｂの両端部を重ねて支柱５に当てがい、各支柱５の前面で重なった２枚のフェンス体Ｆｂの端部を、ここでは各横メンバの組２における２本の平行な鋼棒の間に、いわゆるＵボルトや金属ベルトなどによる止金具７を夫々に配置し、Ｕボルトの場合には各ボルトを締付け、各フェンス体Ｆｂを各支柱５に固定取付けすることにより、防獣フェンスＰＦに形成される。
【００２５】
上記のように設置される防獣フェンスＰＦは、上記のフェンス体Ｆｂにおいて述べた特長，利点がそのまま防獣フェンスＰＦにおいても発揮されるほか、次のような利点がある。即ち、各フェンス体Ｆｂは、完全なフレームレスであるため、その左右両端が、立設された各支柱５との間に多少の位置ずれがあっても、問題なく取付けることが出来るのである。
【００２６】
また、各フェンス体Ｆｂは、鋼棒により形成する４〜６ｍｍφの縦メンバと４〜１０ｍｍφの横メンバの組合せにより多数の縦長のスリット３がいわば網目として形成されるので、フレームレスであってもフェンス体全体としての強度が大きいことは勿論のこと、積雪地に設置した場合でも各スリット３から雪が抜け易くて雪の詰まりが少なく、積雪による斜面雪圧、受動雪圧からなる雪圧と積もった雪がもたらす沈降力を受け難く、また、受けたとしてもフェンス体Ｆｂ全体で分散して受け止めるため、前記雪圧などによってフェンスが変形することは殆んどない。なお、このフェンスは、山間地のみに適用するものではなく、平地においても山間地の場合と同様に設置して使用することができる。
【００２７】
以上に述べた従来のフェンス体Ｆｂ、並びに、このフェンス体Ｆｂを使用した防獣フェンス体ＰＦは、平行に並べた縦メンバ１に２本を一組とする横メンバの組２を、当該縦メンバ１の上端側から約４００ｍｍ〜５００ｍｍのピッチで配置し、両メンバ１，２の交点を溶着したものであったが、本発明は、上記例の横メンバの組２に図３に例示するように、副横メンバ２１〜２３を付加して形成したフェンス体Ｆｂ’に適用するものであるが、このフェンス体Ｆｂ’は、図１のフェンス体Ｆｂよりも下部の強度をより高めた構造のものである。
【００２８】
即ち、図３の本発明を適用する一例のフェンス体Ｆｂ’では、縦メンバ１’の高さ（長さ）を少し大きくし、並べた縦メンバ１’の上に、約４００ｍｍピッチで４組の横メンバの組２を配置する点は、図１のフェンス体Ｆｂと略同じ構成であるが、図３のフェンス体Ｆｂ’の例では、上から３番目と４番目の横メンバの組２の間に１本の副横メンバ２１を配置すると共に、最下の横メンバの組２の下方に約９０〜１００ｍｍの間隔で２本の副横メンバ２２，２３を配置して、交叉した両メンバ１’，２，２１〜２３を溶着することにより、本発明を適用する一例のフェンス体Ｆｂ’を形成した。
【００２９】
フェンス体Ｆｂ’を図３のように形成すると、このフェンス体Ｆｂ’を使用して、図２の例と同趣旨で防獣フェンスＰＦを設置するとき、各フェンス体Ｆｂ’の副横メンバ２２，２３は地中に埋設され、また各フェンス体Ｆｂ’の下方部方は縦，横メンバにより形成される網目が小さくなるので、フェンス下部の強度を全体として高めることができる効果が得られる。
【００３０】
上記のように形成されるフェンス体Ｆｂ’は、例えば山間部に通された鉄道や自動車道に沿って、例えば防獣フェンスＰＦとして設置されるので、この点について図４，図５により説明する。
【００３１】
まず、図３のフェンス体Ｆｂ’を、その一枚の幅を、支柱間隔の単位として複数の支柱５を地上Ｇに立設する。この支柱５自体の構造やその立設基礎６は、従来フェンスの場合と略同様である。本発明フェンスは、立設した各支柱５の路面（鉄道又は道路）側を前面にし、この前面に、前記フェンス体Ｆｂ’を、その横メンバの組２を外面（縦メンバ１を支柱５の前面に対向させる）に向けて、各フェンス体Ｆｂ’の両端部を重ねて支柱５に当てがい、各支柱５の前面で重なった２枚のフェンス体Ｆｂ’の端部を、ここでは各横メンバの組２における２本の平行な鋼棒の間に、いわゆるＵボルトや金属ベルトなどによる止金具７を夫々に配置し、Ｕボルトの場合には各ボルトを締付け、各フェンス体Ｆｂを各支柱５に固定取付けすることにより、防獣フェンスＰＦの一例に形成される。
【００３２】
上記のように設置される防獣フェンスＰＦは、上記のフェンス体Ｆｂ’において述べた特長，利点がそのままこの防獣フェンスＰＦにおいても発揮されるほか、次のような利点がある。即ち、各フェンス体Ｆｂ’は、完全なフレームレスであるため、その左右両端が、立設された各支柱５との間に多少の位置ずれがあっても、問題なく取付けることが出来るのである。
【００３３】
また、各フェンス体Ｆｂ’は、鋼棒により形成する４〜６ｍｍφの縦メンバと４〜１０ｍｍφの横メンバの組合せにより多数の縦長のスリット３がいわば網目として形成されるので、フレームレスであってもフェンス体全体としての強度が大きいことは勿論のこと、積雪地に設置した場合でも各スリット３から雪が抜け易くて雪の詰まりが少なく、積雪による斜面雪圧、受動雪圧からなる雪圧と積もった雪がもたらす沈降力を受け難く、また、受けたとしてもフェンス体Ｆｂ’全体で分散して受け止めるため、前記雪圧などによってフェンスが変形することは殆んどない。なお、このフェンスは、山間地のみに適用するものではなく、平地においても山間地の場合と同様に設置して使用することができる。
【００３４】
以上に述べた、防獣フェンスＰＦは、各フェンス体Ｆｂ’の縦メンバ１の上端に、図６に例示するような金属製又は合成樹脂製の安全キャップ８をフェンス体Ｆｂ’の全幅に亘り設けられている。即ち、各フェンス体Ｆｂ’の縦メンバの上には、このフェンス体Ｆｂ’の全幅に亘り、断面が略帽状をなす安全キャップを、その側断面が閉じた環状をなすように接合して設けることにより、本発明フェンス体Ｆｂ’の一例に形成される。また、防獣フェンスＰＦは、鉄道，自動車道に沿って防獣フェンスを新設する場合に有用であることは勿論、有刺鉄線などによる簡易タイプの柵しか設けられていない場所に、該有刺鉄線柵に付設する形で設けることもできる。更に、上記フェンス体Ｆｂ’は、その縦メンバ１を最上位の横メンバの組２から上方へ適宜量突出させ、該突出部分を曲げていわゆる「しのび返し」を形成することもある。
【００３５】
本発明のフェンス体Ｆｂ’は、そのフェンス体Ｆｂ’の全高よりも例えば１０００〜１５００ｍｍ程度高く形成されて立設した支柱５の前面に、フェンス体Ｆｂ’の下部を接地乃至は地中に埋めて設け、前記各支柱５のフェンス体Ｆｂ’が設けられない上方部分に、線材を張設していわゆる鹿除け機能を発揮させる形態のフェンスＰＦ’にすることもある。
【００３６】
次に、参考までに、補助フェンス体の実施の形態例について図７，図８により説明する。図７，図８の補助フェンス体ＳＦｂは、先の例における縦メンバ１と略同径であるが、長さ（高さ）を２００〜５００ｍｍに調整した縦メンバ１’を４０〜１００ｍｍ程度の間隔で縦向き平行に並べる一方、この縦メンバ１’の上に、図の例では４本の横メンバの組２’を図７に例示したパターン（間隔）で横向きに平行に並べて縦メンバ１’と横メンバの組２’の交点を溶接により結合して補助フェンス体ＳＦｂの一例に形成したものである。
【００３７】
図７の補助フェンス体ＳＦｂは、その上部を図８に例示したように、ネット状の金網Ｍｎを使用した既設フェンスＰＦ’の下端部に面で重ねて配置すると共に、この補助フェンス体ＳＦｂの下部を地中に埋設し、既設フェンスＰＦ’の支柱或は枠５’を利用して止め金具７’などにより既設フェンスＰＦ’に取付ける。これにより補助フェンス体ＳＦｂは、既設フェンスＰＦ’の下部と地表の間にある隙間から、或は、そのような隙間が殆んどなくてもその下の地面を堀って侵入して来る小動物の侵入を効果的に阻止できる。
【００３８】
【発明の効果】
請求項１の発明は以上の通りであって、特に、山間地に通された自動車道や鉄道に沿って設置するフェンス体を正面幅が５００〜３０００ｍｍ、高さが１０００〜１８００ｍｍのフェンス体であって、このフェンス体は、４〜６ｍｍφの太さで長さが１０００〜１８００ｍｍの鋼棒を５０〜６０ｍｍ間隔で縦向きに平行にして前記正面幅をなすように並べた縦メンバと、４〜１０ｍｍφの太さで長さが前記正面幅と略同長の鋼棒による横メンバの２本乃至３本を幅が５０〜６０ｍｍをなすように横向きに平行に並べる横メンバの組とにより、該複数の横メンバの組を前記縦メンバの上に、当該縦メンバの上端近くから４００ｍｍ〜５００ｍｍの間隔を持たせて配置し、かかる横メンバの組と縦メンバとによりフェンス体をフレームレス形成とすると共に、配置した前記横メンバの組の最下位のものより下方に２００ｍｍ〜７０ｍｍの間隔で前記横メンバと同じ鋼棒による副横メンバを縦メンバの上に配置し、各縦メンバと各横メンバの交叉部を溶接により接合することにより、最下位の横メンバの組より下方に位置する縦メンバを櫛歯状とした櫛歯状部とし、同櫛歯状部は、地中に突刺して埋設されるべく構成したので、フェンス設置場所の地表の凹凸や傾斜の有無に拘わらず縦メンバの下部の櫛歯状部を地中に埋めて設置することができ、フェンスと地上の間に隙間が生じることがなく、地中に入った櫛歯状部によって小動物がフェンス体の下方の地面に穴を堀って通る状況を防止することができる効果がある。また、フェンスの上半側に形成されるスリットは鋼棒による縦，横メンバを溶接して形成した５０〜６０ｍｍラ４００〜５００ｍｍ程度の大きさであるため、人手によってもこのスリットを変形させることは困難であり、ましてや、小動物が前記スリットから抜けることはまずない。仮に小動物がこのスリットに手や爪を掛けようとしても、引掛かりがないためフェンスの上まで登ることが不可能となる効果がある。
【００３９】
また、請求項２の発明によれば、上から３番目と４番目の横メンバの組の間に１本の副横メンバを配置したので、フェンス体下部の強度を著しく高めたフェンス体によってより防獣性の高いフェンス体を形成することが可能となる効果がある。
【００４０】
また、請求項３の発明によれば、縦メンバを最上位の横メンバの組から上方へ適宜量突出させ、該突出部分を曲げてしのび返しを形成したことにより、小動物がフエンス体の上端を飛び越えて柵内に侵入することを防止することができる。
【００４１】
また、請求項４記載の発明によれば、請求項１又は請求項２又は請求項３のフェンス体の正面幅より少し小さい間隔で支柱を複数本立設し、各支柱の前面に請求項１のフェンス体の左、右の側端部を重ねて位置付けると共に、各フェンス体における縦メンバの櫛歯状部を地中に埋設し、前記各支柱の前面に重合されたフェンス体の側端部を、Ｕボルト等の止金具で前記各支柱に固定したことにより、積雪地帯に設けても雪圧などにより変形するおそれがなく耐雪性のある防獣フェンスとして、きわめて有用な効果がある。
請求項５記載の発明によれば、有刺鉄線などによる簡易タイプの柵しか設けられていない場所に、該有刺鉄線柵に付設する形で請求項１または請求項２または請求項３に記載のフェンス体を設けたことにより、従来の金網タイプのフェンスのように、フェンスを二重に設けなくても防獣フェンスとしての効果を十分に発揮することができる効果がある。
【００４２】
請求項６記載の発明によれば、フェンス体は、その全高よりも地上高さが高い支柱に、フェンス体の下部を地中に埋めて取り付けると共に、前記各支柱のフェンス体が設けられない部分には、金属線を張設したことにより、更に防獣性を高めることができる効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention particularly relates to the beast proof performance of a beast proof fence for preventing humans and small animals from invading railroads laid in mountainous areas, tracks and roads already installed along motorways. The present invention relates to a fence body for raising and a beast fence utilizing the same.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, on highways and railway lines running in mountainous areas, from the viewpoint of safety and other considerations, make sure that animals such as foxes, raccoons, wild boars, and other animals do not enter the roads and routes. In addition, a so-called beast proof fence using a wire net formed in a net shape is installed.
[0003]
However, a wire mesh type fence knitted in a net shape creates a frame such as a rectangular shape, stretches the wire mesh on this frame to form a fence body, and attaches it to the support, so the front rectangular frame (Frame) is indispensable, and therefore, in mountainous areas where there are many irregularities in the installation location, gaps of various sizes occur between the fence body and the ground surface, and these gaps do not help prevent the infestation of beasts Has been pointed out. Further, even without such a gap, it is known that a small animal can climb over a fence of a wire mesh type fence by putting hands and claws on the mesh of the mesh, and this is also a problem.
[0004]
In addition, wire mesh type fences are easily deformed by the external force in the shear direction on the surface of the wire mesh, so if a force in this direction is received, the entire fence including the frame is deformed or the wire mesh comes off the frame. There is also a problem that the function as a beast fence is impaired. In particular, in snowy areas, the pressure from the snow accumulated around the fence is applied to the fence in various ways, so if the snow melts, the fence will be deformed or damaged, and it will have to be repaired every year. It is the current situation.
[0005]
In this regard, a similar problem occurs with wire mesh type fences installed on railways and motorways in mountainous areas where people enter and exit relatively, due to mischief of people entering and exiting.
[0006]
Conventionally, in consideration of the above-mentioned problems, fences are double-installed, or a frame is formed of a strong material for snow resistance, and a wire mesh formed by a thick line is attached to this frame to attach the fence. Although measures such as formation are taken, such measures not only increase the cost but also cannot fundamentally solve the above problem.
[0007]

Next, an embodiment of the fence body of the present invention will be described with reference to the drawings using examples. FIG. 1 is a front view of an example of a conventional fence body forming a fence for a beast control, FIG. 2 is a partial front view of an example in which the fence body of FIG. 1 is installed as an example of a fence, and FIG. 3 is a fence to which the present invention is applied. 4 is a partial front view of an example in which the fence body of FIG. 3 is installed, FIG. 5 is a side view of FIG. 2 or FIG. 4, and FIG. 6 is provided with a safety cap on the fence body of FIG. 7 is a front cross-sectional view of an example of the fence body of the present invention, FIG. 7 is a front view of an example of the auxiliary fence body, and FIG. 8 is a front view of an example of use of the auxiliary fence body of FIG.
[0017]
In FIG. 1, Fb is a fence body having a rectangular external shape when viewed from the front, and has the following configuration. That is, reference numeral 1 denotes a vertical member of the fence body Fb. In the example of FIG. 1, steel rods having a thickness of 4 mmφ and a length of 1550 mm are arranged in parallel in a vertical direction at an interval of about 50 mm. It is arranged so as to be the front width of Fb, for example, about 1500 to 2000 mm. Actually, in the case of a design in which the distance between the centers of the pillars described later is 2000 mm, the width of the fence body Fb is formed to be about 2100 mm. The front width of the fence body Fb can be formed to an arbitrary width depending on the number of the vertical members 1 to be used. Specifically, a length suitable for the type of distance between the columns to be installed due to unevenness or inclination at the installation location, or considering the convenience of transportation, it is practical to be about 500 to 3000 mm. is there.
[0018]
Reference numeral 2 denotes a horizontal member which is horizontally arranged on the upper surface of the vertical member 1 which is arranged in a width of about 1500 to 2000 mm by being arranged in parallel in the vertical direction in the above. A pair of horizontal steel rods each having a length of 6 mmφ and having a length equal to or slightly longer than the entire width of the vertical members 1 arranged in the range of 1500 mm to 2000 mm are arranged in parallel at an interval of about 50 mm. On the vertical members 1 arranged as described above, four horizontal member sets 2 are arranged at a pitch of about 400 mm from the upper end of the vertical member 1 in this order. The set 2 of the vertical member 1 and the horizontal member is fixed by welding at each intersection thereof to form a frontless frameless fence body Fb shown in FIG.
[0019]
Here, the set 2 of the lateral members selects the thickness of the steel rod to be used from the steel rods having a thickness of 4 to 10 mmφ in consideration of the environment of the installation location and the like. Choose from The horizontal member set 2 may be formed of three steel rods, and the arrangement interval of the horizontal member sets 2 on the vertical member 1 may be 300 mm or more, for example, about 500 mm. . When the arrangement interval is 500 mm in the above example, three sets of the horizontal members are arranged on the vertical members. In the above-mentioned fence, the horizontal member set 2 uses a steel bar equivalent to or thicker than the vertical member 1, and the usage mode in which two or three steel bars are used as one set is that the fence body Fb is a frameless type. This is because the strength of the entire fence body is increased even in a frameless manner, and the horizontal member set 2 at the upper end of the vertical member 1 has a function that replaces the body edge of the conventional fence.
[0020]
The fence body Fb shown in FIG. 1 is formed by a set 2 of a vertical member 1 having a thickness of 4 to 6 mmφ and a horizontal member having a thickness of 4 to 10 mmφ, and a vertically long window (slit) formed by both members 1 and 2. ) 3 is about 50 mm × 400 mm in size between the cores, so that small animals cannot escape from this slit 3, and of course, the span of the vertical member 1 in this slit 3 is 4-6 mmφ steel. Since it is 400 mm with a rod, it is almost impossible or difficult to bend even by hand, that is, it is difficult to widen the width of the slit 3, so that the small animal deforms it to the opposite side. It is virtually impossible to get out, and it is of course impossible for even a person to deform and pass through the slit 3.
[0021]
Further, in the above frameless fence body Fb, since the length of each slit 3 is 400 mm in this example, even if a small animal catches a hand or a nail on the lower horizontal member set 2, the next horizontal Hands and claws do not reach member set 2 and, therefore, small animals cannot climb over this fence.
[0022]
Further, since the lower end of the fence body Fb is frameless, the vertical member 1 located below the lowermost horizontal member set 2 has a so-called comb-teeth shape due to the mounting manner of the horizontal member set 2 described above. In the example of the figure, since the projection protrudes downward by about 130 mm, in a place where there is unevenness on the ground surface such as a mountainous land, if the comb tooth-shaped portion 4 is installed so as to pierce the ground, the unevenness on the ground surface can be reduced. Irrespective of this, no gap is formed at the lower end of the fence, and the comb teeth 4 are buried in the ground, so that even if a small animal digs a hole under the fence body Fb, the comb teeth Since it is blocked by the shape part 4, it is also possible to prevent passing through from such a hole.
[0023]
The fence body Fb formed as described above is installed as, for example, a beast proof fence PF along, for example, a railway or an automobile road that passes through a mountainous area. This point will be described with reference to FIGS. 2 and 5.
[0024]
First, a plurality of columns 5 are erected on the ground G using the width of one fence body Fb in FIG. The structure of the column 5 itself and its standing foundation 6 are substantially the same as those of the conventional fence. The beast proof fence has the road surface (railway or road) side of each standing pillar 5 on the front side, and the fence body Fb on the front face, the horizontal member set 2 on the outside face (the vertical member 1 on the front face of the pillar 5). , The ends of the two fences Fb overlapped on the front surface of each of the struts 5 and the end portions of the two fences Fb, which are overlapped on the front surface of each of the struts 5, are each used as a set of each of the horizontal members. 2, a fastener 7 such as a so-called U-bolt or a metal belt is arranged between two parallel steel rods, and in the case of a U-bolt, each bolt is tightened, and each fence body Fb is attached to each column 5. By being fixedly attached, it is formed in the beast proof fence PF.
[0025]
The beast proof fence PF installed as described above has the following advantages in addition to the features and advantages described in the above-mentioned fence body Fb being directly exhibited in the beast proof fence PF. That is, since each fence body Fb is completely frameless, it can be mounted without any problem even if the left and right ends are slightly displaced from the upright columns 5.
[0026]
Further, each fence body Fb is frameless because a large number of vertically long slits 3 are formed as a mesh by a combination of 4 to 6 mmφ vertical members and 4 to 10 mmφ horizontal members formed by steel rods, so to speak. Not only is the strength of the fence as a whole large, but also when it is installed in a snowy area, snow easily escapes from each slit 3 and there is little snow clogging. The fence is hardly deformed by the snow pressure or the like because it is hard to receive the sinking force caused by the snow and even if it is received, it is dispersed and received by the entire fence body Fb. Note that this fence is not applied only to a mountainous area, and can be installed and used on a flat ground in the same manner as in a mountainous area.
[0027]
The above-described conventional fence body Fb and the beast-proof fence body PF using the fence body Fb include a vertical member 1 arranged in parallel, and a horizontal member set 2 having two pairs. The member 1 was arranged at a pitch of about 400 mm to 500 mm from the upper end side, and the intersection of the two members 1 and 2 was welded. The present invention is illustrated in FIG. As described above, the present invention is applied to the fence body Fb ′ formed by adding the sub lateral members 21 to 23, and the fence body Fb ′ has a structure in which the strength of the lower part is higher than that of the fence body Fb of FIG. belongs to.
[0028]
That is, in the example of the fence body Fb ′ to which the present invention shown in FIG. 3 is applied, the height (length) of the vertical members 1 ′ is slightly increased, and four sets of the vertical members 1 ′ are arranged at approximately 400 mm pitch on the arranged vertical members 1 ′. The arrangement of the horizontal member set 2 is substantially the same as that of the fence body Fb of FIG. 1, but in the example of the fence body Fb ′ of FIG. 3, the third and fourth horizontal member sets 2 One sub-horizontal member 21 is arranged between them, and two sub-horizontal members 22 and 23 are arranged below the lowermost horizontal member set 2 at intervals of about 90 to 100 mm. An example of the fence body Fb 'to which the present invention is applied was formed by welding the members 1', 2, 21 to 23.
[0029]
When the fence body Fb ′ is formed as shown in FIG. 3, when the beast proof fence PF is installed using the fence body Fb ′ in the same manner as in the example of FIG. 2, the sub lateral member 22 of each fence body Fb ′ is installed. , 23 are buried in the ground, and the mesh formed by the vertical and horizontal members becomes smaller in the lower part of each fence body Fb ', so that the effect of increasing the strength of the lower part of the fence as a whole can be obtained.
[0030]
The fence body Fb 'formed as described above is installed as, for example, a beast proof fence PF along, for example, a railroad or a motorway passed through a mountainous area. This point will be described with reference to FIGS. .
[0031]
First, a plurality of struts 5 are erected on the ground G using the width of one fence body Fb ′ in FIG. The structure of the column 5 itself and its standing foundation 6 are substantially the same as those of the conventional fence. The fence of the present invention has the road surface (railway or road) side of each of the columns 5 standing upright, and the fence body Fb ′ is attached to the front surface of the fence body Fb ′. (To be opposed to the front surface), the both ends of each fence body Fb ′ are overlapped and applied to the support 5, and the ends of the two fence bodies Fb ′ overlapping on the front surface of each support 5 are each A so-called U-bolt or a metal belt or the like fastener 7 is arranged between two parallel steel bars in the member set 2, and in the case of a U-bolt, each bolt is tightened, and each fence body Fb is connected to each other. By being fixedly attached to the column 5, it is formed as an example of the beast-proof fence PF.
[0032]
The beast proof fence PF installed as described above has the following advantages in addition to the features and advantages described in the fence body Fb ′ described above being exhibited in this beast proof fence PF as it is. That is, since each fence body Fb 'is completely frameless, it can be mounted without any problem even if the left and right ends are slightly displaced from the upright columns 5. .
[0033]
Each fence body Fb 'is frameless because a large number of vertically long slits 3 are formed as meshes by a combination of 4 to 6 mm vertical members and 4 to 10 mm horizontal members formed by steel rods. In addition to the fact that the strength of the entire fence body is large, even when installed in a snowy area, the snow easily escapes from each slit 3 and there is little snow clogging. The fence is hardly deformed by the snow pressure or the like because it is hard to receive the sinking force caused by the accumulated snow and even if it is received, it is dispersed and received by the entire fence body Fb ′. Note that this fence is not applied only to a mountainous area, and can be installed and used on a flat ground in the same manner as in a mountainous area.
[0034]
As described above, the beast proof fence PF has a safety cap 8 made of metal or synthetic resin as illustrated in FIG. 6 over the entire width of the fence body Fb ′ at the upper end of the vertical member 1 of each fence body Fb ′. Is provided. That is, a safety cap having a substantially hat-shaped cross section is joined to the vertical member of each fence body Fb 'over the entire width of the fence body Fb' so that the side cross section forms a closed ring. By providing, it is formed as an example of the fence body Fb ′ of the present invention. The beast proof fence PF is useful not only when newly installing a beast proof fence along a railway or a motorway, but also in a place where only a simple type fence such as a barbed wire is provided. It can also be provided in a form attached to a wire fence. Further, the fence body Fb ′ may have the vertical member 1 protruding upward from the uppermost horizontal member set 2 by an appropriate amount, and bend the protruding portion to form a so-called “stretch back”.
[0035]
In the fence body Fb ′ of the present invention, the lower part of the fence body Fb ′ is buried in the ground or in the ground on the front surface of the upright column 5 formed, for example, about 1000 to 1500 mm higher than the overall height of the fence body Fb ′. In some cases, a wire is stretched over an upper portion of each of the struts 5 where the fence body Fb 'is not provided to form a fence PF' having a so-called deer repelling function.
[0036]
Next, for reference, an embodiment of an auxiliary fence body will be described with reference to FIGS. The auxiliary fence body SFb in FIGS. 7 and 8 has substantially the same diameter as the vertical member 1 in the previous example, but the vertical member 1 ′ whose length (height) is adjusted to 200 to 500 mm has a length of about 40 to 100 mm. In the example shown in the figure, a set 2 ′ of four horizontal members is arranged in parallel in the pattern (interval) illustrated in FIG. The intersection of 'and the set 2 of horizontal members is joined by welding to form an example of the auxiliary fence body SFb.
[0037]
As shown in FIG. 8, the auxiliary fence body SFb of FIG. 7 is arranged on the lower end of the existing fence PF ′ using the net-shaped wire mesh Mn, and the upper part of the auxiliary fence body SFb is illustrated. The lower part is buried in the ground, and is attached to the existing fence PF 'by a stopper 7' or the like using the support or the frame 5 'of the existing fence PF'. As a result, the auxiliary fence SFb can penetrate small animals that enter from the gap between the lower part of the existing fence PF 'and the surface of the ground or by digging the ground under the gap even if there is almost no such gap. Can be effectively prevented.
