Description

【0001】
【発明の属する技術分野】
この発明は、土地の境界や測量点などを表示するのに用いられるキャップ付きの杭に関するものである。
【0002】
【従来の技術】
一般に、この種の杭は、先端部が地中に打ち込まれる棒状の本体の頭部に、土地の境界、測量点、埋設物などを示す標示が付された標示板を固定している。そして、土地の測量時等には、本体の頭部を叩いて先端部から地中に打ち込む。
【0003】
【発明が解決しようとする課題】
ところが、以上の杭は、地中に打ち込むとき、標示板に付した標示が傷付いて不明瞭になり易い。また、地面から露出する頭部が本体と同一の材料、例えばリサイクル樹脂で形成されており、目的に応じて頭部の材質を選択できない。しかも、杭は、地中への打ち込み時に不測に回転することがあり、このとき、標示板に付した標示の方向が狂ってしまう。
【0004】
本発明の目的は、標示を傷付けることなく、その明瞭性を確保し、しかも、本体の打ち込み時に、たとえ回転しても標示を正確に設定できるようにすることにある。
【0005】
【課題を解決するための手段】
上記目的を達成するため、請求項1記載の杭は、地中に打ち込まれる杭であって、先端部から地中に向かう棒状の本体の頭部に、円形外周面をもつ被嵌部を形成し、この被嵌部の外周に標示付きのキャップを被せ、前記キャップは、外周が四角形であり、前記本体は樹脂製で先端部が先細りの形状であり、前記キャップの内面に先端側が弾性変形可能な係合片が形成され、前記本体は、前記被嵌部に前記係合片が係止される係止部が形成され、前記係止部は、上部側から下方に向かって径方向外方に傾斜し、前記キャップを前記被嵌部に上方から下方へ被せるときに前記係合片を弾性変形させながら案内するためのテーパ面と、前記テーパ面の下部側に設けられ、前記キャップを前記被嵌部から上方へ抜き出すときに前記係合片を係止保持して抜け止めするための係止段部とを備えている。
【0006】
土地の測量を行うような場合は、先ず、キャップを取外した状態で本体のみを多数打ち込んで行き、この後、本体より小さな多数のキャップを持ち運んで、頭部の被嵌部に被せて行く。このようにすることにより、作業性を高めながら、キャップの標示を傷付けることなく、その明瞭性を確保できる。また、種々の材料からなるキャップを用意しておき、目的に合わせて選択したキャップを本体に被せることができる。さらに、本体の打ち込み後にキャップを被せるから、打ち込み時に本体が回転しても、キャップの標示を正しい方向に合わせて本体にキャップを被せればよいので、標示を正確に設定できる。また、キャップを被せたのちに標示を修正したい場合、キャップを被嵌部の円形外周面に沿って回転させることにより、標示が修正されて正しい位置に設定される。
また、前記キャップの外周を四角形としているから、キャップを回転して標示を正しい位置に修正するとき、このキャップを金具を用いて容易に回転させられる。
さらに、前記キャップの内面に形成された係合片が、弾性変形しながら前記被嵌部に設けた係止部のテーパ面で案内され、その下部の係止段部に係止保持されるので、キャップを被嵌部に回転可能で抜止め不能にワンタッチ装着できる。
【0008】
本発明の好ましい実施形態では、前記本体を丸棒により形成している。この実施形態によれば、丸い頭部側にキャップを回転可能に被せ易い
【0009】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。
図1は第1実施形態を示し、杭Aは、細長い丸棒からなる本体1と、これとは別体の標示20付きのキャップ2とで構成する。
【0010】
前記本体1は、その下部に、地中に打ち込まれる先鋭状の先端部11を有するとともに、上方の頭部12側には、キャップ2が回転可能に被嵌される円形外周面をもった被嵌部13を設けている。また、この被嵌部13には、これに被せるキャップ2を回転可能で長手方向への抜止め不能に保持するための複数の係止部14が形成されている。これら係止部14は、図2で明らかなように、上部側から下方に向かって径方向外方に傾斜し、後述するキャップ2の係合片を案内するためのテーパ面14aと、このテーパ面14aの下部側に設けられ、係合片を係止保持するための係止段部14bを備えている。
【0011】
前記キャップ2は、図1に示すように、4つの縦壁21と、その上部側に設けられた上壁22をもち、下方に開口した四角形状とされ、この上壁22の外表面に、標示20の一例として土地の測量点を示す矢印を付している。また、図2に示すように、前記縦壁21の内面には、先端側が上向き状とされ、前記係止部14の係止段部14bに係合する弾性変形可能な複数の係合片23を一体に形成する。勿論、係合片23を設けずに、縦壁21の内面を円形に形成して、前記係止部14の突出端との圧接ないし摩擦接触により、キャップ2の抜け止めを行ってもよい。
【0012】
図2のキャップ2は、プラスチック製のものを示し、その成形時に係合片23を一体に形成している。キャップ2は、アルミニウムやステンレスなどの金属で形成してもよく、これに係合片23を設ける場合には、例えば縦壁21に切り目を入れて、係合片23を切り起こし手段により形成することができる。
【0013】
ところで、設置場所などによっては、燃えにくい石、コンクリート、金属製などのキャップが、特に、重要場所に用いる場合は、外観良好な美しい石、金属、セラミックス製などのキャップが要求されることがある。これに対し、本発明は、本体とキャップが別体なので、種々の要求に応じてキャップのみを前記種々の形状のものに取り替えることができる。
【0014】
そして、土地の測量などを行う場合で、図1の杭Aを地中に打ち込むときには、次のような手順で行う。先ず、キャップ2を被せない状態で、頭部12の被嵌部13が地上に露出するように、本体1のみを多数地中に打ち込んで行く。このとき、頭部12に緩く嵌まる打込み用のキャップを別途用意しておき、この打込み用キャップを頭部12に被せて打ち込むことにより、頭部12の傷みを防止できる。この後、多数のキャップ2を持ち運びながら、要求に応じた標示および材質のものを選択し、本体1の頭部12に設けた被嵌部13に順次被せて行く。このとき、キャップ2の標示20を正しい方向に向けて、キャップ2を頭部12に被せ、上方から押し込む。すると、キャップ2側の係合片23が、弾性変形しながら被嵌部13に設けた係止部14のテーパ面14aで案内され、その下部の係止段部14bに係止保持されるので、キャップ2を被嵌部13に回転可能で抜止め不能にワンタッチ装着できる。
【0015】
このように、標示を付する作業者は、予め本体1を打ち込んだのち、小さなキャップ2のみを持ち運んで、順次、本体1に被せればよいから、大きな本体1を持ち運ぶのに比べて、作業性がよい。また、打ち込み時にはキャップ2が装着されていないから、打ち込み作業によってキャップ2の標示20を傷付けることがないので、標示の明瞭性を確保できる。
【0016】
キャップ2を装着した後、測量点を示す標示20を正しい方向に修正する必要が生じたときには、例えば図3のように、キャップ2に嵌合可能な四角形状の枠体31と、握り部32をもつ金具3を使用する。そして、地面Bに打ち込まれた本体1に被せたキャップ2の外周囲に枠体31を嵌合し、握り部32を把持して左右方向に回転させることにより、キャップ2を被嵌部13の係止部14に沿って回転させて、標示20の方向を正しい位置に修正する。
【0017】
前記被嵌部13にキャップ2を被せるときには、その内部に接着剤を付けておくとよい。すると、標示20の修正後に接着剤が硬化することにより、この標示20を正確な位置に固定できる。なお、標示20の修正は、以上の金具3のほかにスパナなどを用いて行ってもよい。
【0018】
図4に示す第2実施形態では、本体1として細長い角棒を用いている。この本体1は、地中に正確かつ抵抗少なく打ち込むため、頭部12を4角柱状とし、主部15を長手方向に延びる4つの尾根部16を有する横断面星形に形成して、この主部15の下方に弾頭形状の先端部11を設けている。そして、頭部12の上方に、キャップ2が被せられる円柱状の被嵌部13を突設している。この場合は、キャップ2の内部に被嵌部13に嵌合可能な断面円形の嵌合凹部を形成して、この嵌合凹部を被嵌部13に回転可能に保持させるようにする。
【0019】
この第2実施形態の場合にも、前述した場合と同様に、本体1の地中への打ち込み後に、その被嵌部13にキャップ2を被せる。この構成によっても、キャップ2の標示20を傷付けることなく明確に表示できる。また、キャップ2を被嵌部13に対し回転させることより、標示20の向きの修正もできる。さらに、種々の要求に応じてキャップ2の材質が自由に選択可能となる。また、キャップ2と被嵌部13を接着剤で一体化することにより、キャップ2がいたずら等により取り外されたりすることなく、その標示20を正確な位置に固定できる。
【0020】
以上の各図に示す本体1は、主に樹脂成形時に生じるかすや樹脂製品の廃物などを原料とするリサイクル樹脂を用い、本体1の成形時に被嵌部13を一体に形成する。また、各図の実施形態では、外周が四角形のキャップ2を示したが、これは三角形、五角以上の多角形または円形であってもよい。
【0021】
さらに、上記各実施形態では、被嵌部13に複数の係止段部14を形成したが、この係止段部14は必ずしも設ける必要はなく、被嵌部13は凹凸のない円周面をもつ円柱状に形成してもよい。その場合、キャップ21の内周面に摩擦力を与えるための小さな凹凸を設けるのが好ましい。また、標示20は、土地の測量点を示す矢印に限られるものではなく、埋設配管の位置、測量始点の方角など、種々の標示を使用できる。
【0022】
【発明の効果】
以上のように、本発明によれば、キャップの標示を傷付けることなく、この標示の明瞭性を確保でき、しかも、種々の目的に応じて材質の異なる各種のキャップを自由に選択して取付けることができる。また、本体の打ち込み時に、たとえ回転しても標示を正確に表示できる。
