【発明の属する技術分野】
本発明は、仮設工事用サポートにおいて、仮設工事用サポートの全長を微調整することができる仮設工事用サポートにおけるピン受け用ナットに関するものである。
【0002】
【従来の技術】
従来、仮設工事用サポートの全長を微調整することができるピン受け用ナットは、例えば、特開平11−107546号公報に開示された環状のナットが公知である。
【0003】
【特許文献1】
[特開平11−107546号公報]
【0004】
【発明が解決しようとする課題】
前記特許文献1で開示された仮設工事用サポートにおけるピン受け用ナットは、該特許文献1の図4(A)・(B)に符号「16」で示されているように、環状のものである。従って、前記環状のピン受け用ナットを、螺軸部17において、螺合回転させる場合、前記ピン受け用ナットを回転させるための回転金具を掛止する手段を備えていないため、該環状のピン受け用ナットを、迅速に、且つ容易に回転させることが困難であるという課題があった。
【0005】
本発明は、前記課題を解決すべくなされたもので、ピン受け用ナットの外周に、該ピン受け用ナットを回転させる回転金具を装入して掛止する、少なくとも1個の回転金具受けを突設した仮設工事用サポートにおけるピン受け用ナットを提供しようとするものである。
【0006】
【課題を解決するための手段】
本発明は、下端にベースプレートを備えた大径の下方パイプに、上端に受け板を備えた小径の上方パイプを昇降自在なるよう嵌挿すると共に、該上方パイプに直径方向にピンを貫通するピン孔を長さ方向に所定間隔を有して複数個穿設し、更に、前記下方パイプの上方部外周に適宜長さの雄螺子を周設すると共に、該雄螺子の直径方向両側に長さ方向と平行な長孔をそれぞれ穿設して形成された仮設工事用サポートの雄螺子に螺合されるピン受け用ナットにおいて、前記雄螺子に螺合する環状の螺合部の外周面に、外側端に起立片を備え、且つ該起立片と螺合部間に回転金具を装入して掛止する掛止凹部を設け、更に前記起立片と対面する螺合部の周壁に、回転金具の抜け止め用突起を突設してL字状に形成された回転金具受けを少なくとも1個突設するという手段を採用することにより、上記課題を解決した。
【0007】
【発明の実施の形態】
本発明の形態を図面に基づいて詳細に説明する。図1は本発明ピン受け用ナットを螺合して示す仮設工事用サポートの全体の斜視図、図2は同組立分解斜視図である。すなわち、仮設工事用サポート1は、下端にベースプレート2を備えた大径の下方パイプ3に、上端に受け板4を備えた小径の上方パイプ5が昇降自在なるよう嵌挿されると共に、該上方パイプ5には直径方向に、サポート長さを調整するピン6を貫通するピン孔7が長さ方向に所定間隔を有して複数個穿設され、更に、前記下方パイプ3の外周上端縁から下方方向へ適宜長さに雄螺子8が周設されると共に、該雄螺子8の直径方向両側に長さ方向と平行な長孔9をそれぞれ穿設し、且つ前記雄螺子8に本発明ピン受け用ナット10を螺合して形成されている。
【0008】
前記ピン受け用ナット10は、図3に示すように、環状の螺合部11の内周面に、前記雄螺子8に螺合する雌螺子12を周設する一方、前記螺合部11の外周面に、該ピン受け用ナット10を回転させる回転金具13を装入して掛止する回転金具受け14が突設されている。前記回転金具受け14は、外側端に起立片15を突設すると共に、前記起立片15と該螺合部11間に、前記ピン受け用ナット10の回転金具13を装入して掛止する装入凹部16を設けてL字状に形成されている。
【0009】
なお、特に限定する必要はないが、好ましくは、前記起立片15と対面する螺合部11の周壁に、前記回転金具13の抜け止め用の突起17を突設することが推奨される。
【0010】
前記構成より成る本発明仮設工事用サポートにおけるピン受け用ナットの作用について説明すると、図4に示すように、大径の下方パイプ3に小径の上方パイプ5を嵌挿して、該上方パイプ5を下方パイプ3に対して適宜昇降させて、サポート1の全長を使用場所の高さ程度に大まかに調整し、かかる状態において、長孔9内に位置する所定のピン孔7にピン6を貫挿した後、ピン受け用ナット10に突設された回転金具受け14の装入凹部16に、該装入凹部16に装入して掛止できる径を有する、例えばバールやドライバー、あるいは鋼棒等を回転金具13(図1においては、バールが図示されている)として装入して掛止し、該回転金具13を持って前記ピン受け用ナット10を正方向へ回転させることにより、該ピン受け用ナット10の上端周縁が前記ピン6の下面に当接する。
【0011】
そして、その状態で更に前記回転金具13を持ってピン受け用ナット10を更に正方向へ回転させると、前記ピン6の下面に当接しているピン受け用ナット10が上昇するので、前記ピン6が徐々に押し上げられて、該ピン6と共に上方パイプ5が上昇して、サポート1全体の全長の微調整ができるのである。
【0012】
また、前記回転金具13を持ってピン受け用ナット10を逆方向へ回転させると、該ピン受け用ナット10が下降するので、上方パイプ5はその自重で、前記ピン6が前記ピン受け用ナット10に当接したまま下降し、サポート1全体の全長の微調整ができる。
【0013】
すなわち、本発明仮設工事用サポートにおけるピン受け用ナット10は、装入凹部16に装入して掛止できる大きさの金具であれば、種類を問わず回転金具13として使用できる。また、ピン受け用ナット10がピン6に当接する前は、単に起立片15を持って手で回転させることができる。更に、前記回転金具13が、抜け止め用の突起17の下方に掛止できる大きさのものであれば、該回転金具13が回転操作中に、装入凹部16から離脱することなく、安全な回転作業が可能である。
【0014】
なお、図1においては、回転金具受け14は、螺合部11の外周面に1個突設されれているが、図5・図6に示すように3個でもその目的を達することができ、また、図示していないが、2個、あるいは3個以上であってもその目的を達することかできる。そして、回転金具受け14が、2個以上螺合部11の外周面に突設されている場合は、そのいずれかの回転金具受け14に回転金具13を装入掛止して使用する。
【0015】
図7は、本発明工事用サポートの更に他の実施の形態におけるピン受け用ナットを取付けたサポートの全体の斜視図、図8は同ピン受け用ナットの斜視図である。図7・図8に示す本発明の他の実施の形態におけるピン受け用ナット10は、螺合部11の外周面直径方向両側に、該ピン受け用ナット10を回転させる回転金具13を装入して掛止する回転金具受け24が、それぞれ突設されている。前記回転金具受け24は、肉厚の突起部25の中央に回転金具13(図7においては、丸鋼棒が図示されている)を貫通させる装入孔26を設けて形成されている。
【0016】
前記本発明の他の実施の形態による架設工事用サポートにおけるピン受け用ナットの作用について説明すると、前記図1に示すものが、回転金具13を装入凹部16に装入して掛止するのに対し、図7に示すものは、装入孔26に回転金具13を装入して掛止する点が異なるだけで、その他の作用および効果は、前記図4に示すものと同一であるので説明は省略する。
【0017】
そして、図7・図8においては、回転金具受け24は、ピン受け用ナット10の螺合部11の外周面に2個突設されているが、図9に示すように、1個であってもよく、また図示していないが、3個以上であってもその目的を達することができる。
【0018】
【発明の効果】
本発明は上述のようであるから、特別な専用の回転金具を使用することなく、装入凹部に掛止できる金具であれば、種類を問わず、いずれも回転金具として使用して、ピン受け用ナットを簡単に回転させることができるので便利であり、また回転金具受けを押圧することにより、ピン受け用ナットを手で回転させることもできるという優れた効果を奏するのである。
