Description

【０００１】
【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であって、前記雄螺子に螺合する環状の螺合部の外周面に、少なくとも１個の回転金具受けを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。
