Description

【０００１】
【発明の属する技術分野】
本発明は、アンカー工法用受圧板に関し、詳しくは、法面に接地自在な接地底板部と、前記接地底板部に形成したアンカー部材を挿通可能なアンカー挿通部と、前記アンカー部材を係止可能な係止部と、前記接地底板部に立設された竪補強板部とを備えて、金属材料で形成してあり、地中に係止した前記アンカー部材を用いて前記法面に圧接して地すべりや法面崩壊を防止するアンカー工法用受圧板に関する。
【０００２】
【従来の技術】
従来、図８に示すように、一般には底面を法面Ｆに接地自在にした接地面３ａに形成してある方形の平板部１ａの中央部に、アンカー挿通部５を形成すると共に、地山Ｂに固定されたアンカー部材８と係止可能な受け座６ｂを備えた係止部６を設け、前記係止部６から前記平板部１ａの各辺に平行に上側に突出形成された十字状の補強部１ｂを前記平板部１ａ上に形成したプレキャストコンクリート製の受圧板１が用いられている。この受圧板１は嵩張り、重量は３〜４トンにも達するものであるが、これを法面Ｆ上に運搬して、前記アンカー挿通部５に前記アンカー部材８を挿通させた状態で、前記アンカー部材８の先端部に形成した雄ねじに螺合させた締結部材９を前記受け座６ｂに向けて締め付けることによって、前記アンカー部材８を緊張して、前記受圧板１を前記地山Ｂに固定し、前記接地面３ａを前記法面Ｆに圧接するのである。
【０００３】
【発明が解決しようとする課題】
上記従来のアンカー工法用受圧板においては、受圧板自身を透して接地面にて接地する地山へ排水する排水性がなく、従って、降雨に際して、法面上に降り注いだ雨は、そのまま前記アンカー工法用受圧板の上を流れ落ち、時として大量の雨水を道路上に流して道路交通障害を招くこともあり、地中に雨水を浸入させないから、地山の保水力を損なうという問題もある。さらに、塗装等を施してはいるものの、外観的にも傾斜面の美観を損なうものでもある。
また、従来のアンカー工法用受圧板では、受圧板１自身が嵩高いものであり、重量物であるから、施工場所に輸送するにも通常のトラック輸送はできず、重量物輸送用のトレーラを用いて輸送するなど、現場への搬送上にも問題があった。また、現場施工の際に、大重量用の重機を必要とするという問題もあった。このため、輸送に際して嵩張らず、しかも搬送重量が従来よりも軽減されたものが望まれていた。
そこで、本発明は、上記の問題点を解決し、環境保全に資するものであり、しかも、輸送に際して従来よりも軽量であるアンカー工法用受圧板を提供することを目的とする。

〔作用効果〕
上記請求項１に記載の本発明に係るアンカー工法用受圧板の特徴構成によれば、排水性を有することで、環境保全に資するものとなり、且つ、受圧板自身を軽量化することもできる。
【００１２】
つまり、法面に複数の竪補強板部が互いに交差するアンカー工法用受圧板を取付けるので、法面に沿って接地底板部も傾斜しており、互いに交差する複数の竪補強板部と接地底板部とで囲まれた形状となる連接部が形成されるため、受圧板には比較的水が溜まり易くなる。ところが、そのような連接部の接地底板部に水抜き穴を形成することでその水抜き穴から水を地山に排出することができるので、連接部には水が溜まり難くなり、アンカー工法用受圧板の排水性を向上させることができる。よって、アンカー工法用受圧板が錆などにより腐食するのを防止し易く、その耐久性を向上させることもできる。
【００１３】
従って、前記水抜き穴を通して受圧板上に降り注いだ降雨を地山の地中に浸透させるから、前記地山に保水性を付与できる。
【００１４】
また、竪補強板部どうしが互いに交差する連接部の接地底板部に水抜き穴を形成してあるから、受圧板自身を軽量化することもできる。
【００１５】

そして、水が溜まりにくいので、前記周縁竪補強板部で囲まれた空間の湿度を適度に保つことができ、植栽した植物が根腐れしたりすることをより防止し易くすることができる。従って、傾斜面の外観をより美観に富んだものにすることもできる。
【００１８】

【００２２】
つまり、法面に周縁竪補強板部と縦貫竪補強板部とが交差するアンカー工法用受圧板を取付けるので、法面に沿って接地底板部も傾斜しており、接地底板部と周縁竪補強板部、縦貫竪補強板部とで囲まれた形状となる連接部が形成されるため、受圧板には比較的水が溜まり易くなる。ところが、そのような連接部の接地底板部に水抜き穴を形成することでその水抜き穴から水を地山に排出することができるので、連接部には水が溜まり難くなり、アンカー工法用受圧板の排水性を向上させることができる。よって、アンカー工法用受圧板が錆などにより腐食するのを防止し易く、その耐久性を向上させることもできる。
そして、水が溜まりにくいので、前記周縁竪補強板部で囲まれた空間の湿度を適度に保つことができ、植栽した植物が根腐れしたりすることをより防止し易くすることができる。従って、傾斜面の外観をより美観に富んだものにすることもできる。

【発明の実施の形態】
〔実施形態〕
上記本発明のアンカー工法用受圧板の実施の形態の一例について、以下に、図面を参照しながら説明する。図１は、本発明に係るアンカー工法用受圧板の一例について設置状態を示す縦断面図であり、図２は、本発明に係るアンカー工法用受圧板の他の例について設置状態を示す縦断面図であり、図３は図２に示したアンカー工法用受圧板の平面図であり、図４はその組立説明用の斜視図である。尚、前記従来の技術において説明した要素と同じ要素並びに同等の機能を有する要素に関しては、先の図８に付したと同一の符号を付し、詳細の説明の一部は省略する。
【００４２】
アンカー工法用受圧板は、図１に示すように、地山Ｂの地中に係止したアンカー部材８を用いて法面Ｆに圧接して地すべりや法面崩壊を防止するのに用いられるものである。その受圧板１は、金属材料の一種であるダクタイル鋳鉄で形成して、前記法面Ｆに接地自在な接地底板部３と、前記接地底板部３に形成すると共に前記アンカー部材８を挿通可能なアンカー挿通部５と、前記アンカー部材８を係止可能な受け座６ｂを備えた係止部６と、前記接地底板部３に立設された竪補強板部７とを一体に鋳造して製造する。
【００４３】
また、前記受圧板１は、例えば、図２乃至図４に示すように、十字型に形成し、上下に重ねて組み合わせ可能に分割形成した、複数の分割受圧板１０で構成すればさらによい。図３に示した受圧板１は二つの分割受圧板１０で構成して、つまり、分割受圧板１０における第一分割受圧板１１を第二分割受圧板１２に組み付けて構成してある（図４参照）。この組み付けの時期は、前記受圧板１を法面Ｆに設置する前であることが両分割受圧板１０の組み付けの作業性の面からは好ましいが、前記法面Ｆに前記第二受圧板１２を配置した後に、前記第一分割受圧板１１を前記法面Ｆに仮設置してある第二分割受圧板１２に組み付け、前記アンカー部材８に締結部材９を螺合して締結するようにしてもよい。夫々の前記分割受圧板１０には、前記竪補強板部７として、前記接地底板部３に、径方向に沿って前記係止部６に連接して立設された縦貫竪補強板部７Ｂと、前記接地底板部３の周縁部に沿って周縁竪補強板部７Ａと、径方向に沿って立設された縦貫竪補強板部７Ｂと、前記縦貫竪補強板部７Ｂに一体に連設され、且つ、両側の前記周縁竪補強板部７Ａにも一体に連設された横方向竪補強板部７Ｃとを設ける。そして、上側に重ねられる第一分割受圧板１１に設ける縦貫竪補強板部７Ｂは、前記係止部６に一体に連設し、下側に重ねられる第二分割受圧板１２に設ける縦貫竪補強板部７Ｂは、前記アンカー挿通部５の周壁部に一体に連設する（図４参照）ことが望ましい。
【００４４】
前記第一分割受圧板１１と前記第二分割受圧板１２との夫々に、前記法面Ｆに接地自在な接地底板部３と、前記周縁竪補強板部７Ａと、前記縦貫竪補強板部７Ｂと、前記横方向竪補強板部７Ｃとを備えさせ、前記両分割受圧板１１，１２同士に、上下一方を切り欠いて形成すると共に相互に係合自在な係合部２を形成すればよい。この係合部２を形成するには、上側に配置する前記第一分割受圧板１１に、前記係止部６の下方を切り欠いて形成した第一係合部１１ａを設けると共に、その第一係合部１１ａに前記アンカー挿通部５のアンカー挿通孔に連通する貫通孔６ａを有し、前記アンカー部材８と係合可能な受け座６ｂを備えた前記係止部６を設け、下側に配置する前記第二分割受圧板１２には、前記アンカー挿通部５の上方を切り欠いて形成した第二係合部１２ａを設ければよい。前記両係合部１１ａ，１２ａを互いに係合させる前記係合部２は、前記両分割受圧板１１，１２を組み合わせた状態において、前記両分割受圧板１１，１２における前記接地底板部３の両接地面３ａが、互いに同一面上に位置するように前記係合部２を形成することが望ましい。前記竪補強板部７は、何れも、前記係止部６からの離間距離の増大と共に次第に低くなるように形成すればさらによい。
【００４５】
そして、前記受圧板１は、前記受圧板１を分割構成した場合には、図３に示したように、前記周縁竪補強板部７Ａと前記縦貫竪補強板部７Ｂと前記横方向竪補強板部７Ｃが夫々互いに交差する連接部の前記接地底板部３に水抜き穴２０を形成し、前記水抜き穴２０を備える第一分割受圧板１１を同じく前記水抜き穴２０を備える第二分割受圧板１２に組み付ければよい。そして、この組み付けは、前記法面Ｆに設置する前に行うのが好ましいが、前記アンカー部材８に、前記第二分割受圧板１２のアンカー挿通部５のアンカー挿通孔を外嵌した後に前記第一分割受圧板１１を前記第二分割受圧板１２に組み付けるようにしてもよい。
尚、図示しないが、図１に示したように分割構成しない前記受圧板１についても同様に、前記周縁竪補強板部７Ａと前記縦貫竪補強板部７Ｂと前記横方向竪補強板部７Ｃが夫々互いに交差する連接部の前記接地底板部３に水抜き穴２０を形成すれば良い。
【００４６】
そして、図５に、一例として、分割受圧板１０底面側からみた水抜き穴２０付近の斜視図を示すが、水抜き穴２０は、接地底板部３及び竪補強板部７と一体に連接するように形成してある。
つまり、分割受圧板１０は、周縁竪補強板部７Ａと縦貫竪補強板部７Ｂと横方向竪補強板部７Ｃが夫々互いに交差する連接部の接地底板部３部分近傍に切り欠きが入るようにしてある鋳型により、図５に示すように、その連接部の接地底板部３部分近傍が切り欠かれて形成される水抜き穴２０と、接地底板部３と、竪補強板部７とを一体鋳造して作製してある。
このように鋳造製造することによって、一旦受圧板を作製後に穴を設けるのに比べ、簡便に水抜き穴２０を設けた受圧板を加工できると共に、その水抜き穴の端面をより滑らかに形成することができ、より水抜き穴２０から水を排出し易くすることができる。
【００４７】
図３に示すように、下側に重ねられる第二分割受圧板１２のアンカー挿通部５の周壁部と、その周壁部と貫通孔５とに連接する連接リブとの連接部や、アンカー挿通部５の周壁部で囲まれるコーナー部分や、周縁竪補強板部７Ａで囲まれるコーナー部分などにも水抜き穴２０を設けておいても良い。
また、例えば、図７に示すように、夫々の分割受圧板１０の周縁竪補強板部７Ａ四隅を角状ではなく、丸状に形成しておけば、周縁竪補強板部７Ａで囲まれるコーナー部分は曲面状となり比較的水が溜まり難くなるので、周縁竪補強板部７Ａで囲まれる部分には水抜き穴２０を設けなくても良い。

このように前記水抜き穴２０を形成することによって、殊に周縁竪補強板部７Ａと縦貫竪補強板部７Ｂと横方向竪補強板部７Ｃが夫々互いに交差する連接部において、水が溜まり難くすることができると共に地山Ｂへの排水性を備えさせることができるので、次のような格別の効果を期待することができる。
【００４９】
つまり、前記周縁竪補強板部７Ａを備えることで、前記周縁竪補強板部７Ａの内側の前記接地底板部３上に植栽収容部Ｓを形成できるから、図６に示すように、前記植栽収容部Ｓ内に土を盛り込んで、草木を植栽することができる。さらに、前記植栽収容部Ｓ内に土を盛り込まない場合でも、前記植栽収容部Ｓ内に雨水が貯まっても、前記水抜き穴２０から流出するから前記受圧板１上に降り注いだ雨水は、前記水抜き穴２０から地山Ｂの地中に浸透するから、前記地山Ｂの水涸れも防止できる。尚、前記植栽収容部Ｓ内に土を盛り込んだままに放置しておいても、自然に雑草が生い茂るようになり、周囲の地山Ｂの斜面と異ならない外観を呈するようになる。従って、法面Ｆを保護しながら、周囲と異ならない外観にすることができ、従来のように着色等の手間の掛かる手段を講じなくても景観を維持できるようになる。
【００５０】
以上のように構成した結果、本発明にかかるアンカー工法用受圧板は、図６に示したように、周縁竪補強板部７Ａで囲った接地底板部３上の前記植栽収容部Ｓに土を充填すれば、前記接地底板部３上の前記植栽収容部Ｓ内に溜まる雨水を水抜き穴２０を介して地山Ｂの地中に浸透させて排水でき、前記植栽収容部Ｓ内に植栽した草木の根が水により浮き上がったり、根腐れすることを防止できる。しかも、前記植栽収容部Ｓ内に溜まる水を前記地山Ｂの地中に浸透させることができるから、法面補強を施した地山Ｂに保水性を付与できるようになり、受圧板１が前記地山Ｂの地中に係止されていることで、傾斜面が含水してもそれに起因する前記傾斜面の崩壊を阻止できるから、十分な保水力を前記地山Ｂに付与できる。さらに、受圧板１の上に草木を植栽することが可能であり、景観の維持、並びに、環境保全に資するものとなる。
【００５１】
その上、設置現場への輸送に際しては、前記接地底板部３に前記水抜き孔２０を設けてあることで前記受圧板１が仮に一体に形成してあっても、軽量化されており、さらに、上記の通り竪補強板部を、前記係止部からの離間距離の増大と共に次第に低く形成してあることで、さらに軽量化されている。また、上記の通り分割構成してあれば、分割受圧板１０の形態で輸送すればよいから、従来のように幅・長さ共に長尺のものではなく、通常の輸送車両に積載でき、輸送が容易になる。さらに、輸送車両への積み卸しに際しては、前記分割受圧板１０の単位で取り扱えるから、その重量も従来に比してはるかに軽量であり、揚重機も従来のように大掛かりなものを必要としなくなる。また、施工現場においては、前記分割受圧板１０同士を組み付けて一体にしても、上記の通り軽量化できており、前記一体にした受圧板１を前記アンカー部材８により固定すればよく、前記受圧板１が元々重量を軽減して形成されているから、施工現場における揚重設備も従来のように大掛かりなものを必要としない。
【００５２】
〔別実施形態〕
次に、本発明の他の実施の形態について説明する。
〈１〉上記実施の形態に於いては、アンカー工法用受圧板を、十字型に形成した例について図示説明したが、前記アンカー工法用受圧板は、図示の形状に限るものではなく、放射状に形成してあればよい。例えば径方向の五方向に突出形成した放射状のものであってもよく、これが径方向の六方向に突出した放射形状のものであってもよい。

【００５４】
〈３〉上記実施の形態に於いては、第一係合部１１ａ及び第二係合部１２ａからなる係合部２をアンカー挿通部５の上に形成する例について図に示して説明したが、前記係合部２は、前記アンカー挿通部５から外れた位置に形成してあってもよい。つまり、第一分割受圧板１１に対して下側に配置する第二分割受圧板１２を複数係合させてもよいのである。
【００５５】
〈４〉上記実施の形態に於いては、竪補強板部７は、何れも、係止部６からの離間距離と共に次第に低くなるように形成すればさらによいとして説明したが、前記竪補強板部７を全長にわたって同じ高さに形成してあってもよく、係止部６からの離間距離と共に次第に高くなるように形成してあってもよい。さらに、前記竪補強板部７を段階的に高さを異ならせて形成してあってもよい。尚、前記横方向竪補強板部７Ｃは、幅方向中央部に設けられる縦貫竪補強板部７Ｂから左右に次第に高さが低くなるように形成してあれば、所要曲げ強度を受圧板に付与しながら、受圧板１の強度を損なうことなくさらに軽量化できる。
【００５６】
〈５〉また、別実施形態では、一例として、第一分割受圧板１１を第二分割受圧板１２に組み付けて構成される分割受圧板１０に水抜き穴２０を設ける受圧板について説明したが、そのような分割受圧板１０に限らず、水抜き穴は、〈１〉〜〈４〉にて上述した受圧板などの周縁竪補強板部と縦貫竪補強板部と横方向竪補強板部が夫々互いに交差する連接部の前記接地底板部に設けても良い。
【００５７】
〈６〉図１，２，６で示すごとく、係止部６を覆設する保護キャップ部Ｃは、設けても設けなくても良いが、設けておけば、地山Ｂに接地した後に保護キャップ部Ｃを取付け、保護キャップ部Ｃで係止部６を保護することができる。つまり、係止部６におけるアンカー部材８の先端部に形成した雄ネジや締め付け部材９が、落石などにより破損したり、錆などにより腐食することを防ぎ易くすることができる。そして、係止部６が外部に露出しないので、外観をより良くすることもできる。
〈７〉また、図４に示すごとく、第１分割受圧板１１や第２分割受圧板１２に吊り下げ用孔Ｈを設けても設けなくても良いが、設けておけば揚重機で運搬する際により利便であり、二つの分割受圧板の組み付けの作業性を向上させることもできる。
〈８〉尚、図１〜４，６，７に示すごとく、受圧板１の接地底板部３に補助水抜き穴４を設けても設けなくても良いが、設けておけば周縁竪補強板部７Ａと縦貫竪補強板部７Ｂと横方向竪補強板部７Ｃが夫々互いに交差していない接地底板部３においても補助的に排水性を備えさせることができ、利便である。
