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。
【特許文献１】
[特開平１１−１０７５４６号公報]
【０００３】
【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。
【０００４】
本発明は、前記課題を解決すべくなされたもので、外周の対称位置に回転金具を掛止する掛止突起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。
【０００５】
【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直径方向両側に、外側端に起立片を備えたＬ字型の掛止部をそれぞれ突設すると共に、前記起立片と前記螺合部間に、回転金具を掛止する掛止凹部を設け、更に前記掛止部を構成する各起立片と対面する螺合部の周壁に、上部に前記回転金具の抜け止め用の突起を備えた肉厚部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。
【０００６】
【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。
【０００７】
前記ピン受け用ナット１０は、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の直径方向両側に、外側端に起立片１３を備えたＬ字型の掛止部１４をそれぞれ突設すると共に、前記起立片１３と該螺合部１１間に、前記ピン受け用ナット１０の回転金具１５を掛止する掛止凹部１６を設けて形成されている。
【０００８】
なお、特に限定する必要はないが、好ましくは、前記掛止部１４を構成する各起立片１３と対面する螺合部１１の周壁に、上部に前記回転金具１５の抜け止め用の突起１７を備えた肉厚部１８を突設することが推奨される。
【０００９】
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、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に突設された一方の掛止部１４の掛止凹部１６に、該掛止凹部１６に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１５（図１においては、バールが図示されている）として掛止して、該回転金具１５を持って前記ピン受け用ナット１０を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。
【００１０】
そして、その状態で更に前記回転金具１５を持ってピン受け用ナット１０を正方向へ回転させると、該ピン受け用ナット１０が上昇するので、前記ピン６が徐々に押し上げられて、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。
【００１１】
また、前記回転金具１５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。
【００１２】
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、掛止部１４を設けることにより、掛止凹部１６に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１５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、単に掛止部１４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１５が、抜け止め用の突起１８の下方に掛止できる大きさのものであれば、該回転金具１５が回転操作中に、掛止凹部１６から離脱することなく、安全な回転作業が可能である。
【００１３】
【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、掛止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、ピン受け金具を簡単に回転させることができるので便利であり、また掛止部を押圧することにより、ピン受け金具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。

A plurality of holes are drilled at predetermined intervals in the length direction, and an appropriate length of male screw is provided around the outer periphery of the upper portion of the lower pipe. A pin receiving nut that is screwed to a male screw of a temporary work support formed by drilling a long hole parallel to the direction, and a diameter direction of an annular screwed portion that is screwed to the male screw on both sides, engaging portion of the L-shaped having a standing piece on the outer edge together with respectively protrude, between said upright piece the screw portion is provided with a latching recess for latching the rotating fitting, further wherein On the peripheral wall of the threaded portion facing each upright piece constituting the latching portion, the rotating metal By employing the means of you project from the thick portion having a locking projection for dislodgement, the above-mentioned problems are eliminated.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the entire support for temporary construction shown by screwing a pin receiving nut of the present invention. That is, the temporary work support 1 is inserted into a large-diameter lower pipe 3 having a base plate 2 at its lower end so that a small-diameter upper pipe 5 having a receiving plate 4 at its upper end can be raised and lowered. In the diameter direction, a plurality of pin holes 7 penetrating the pins 6 for adjusting the support length are formed at predetermined intervals in the length direction, and further downward from the outer peripheral upper edge of the lower pipe 3. A male screw 8 is provided in a suitable length in the direction, and long holes 9 parallel to the length direction are formed on both sides in the diameter direction of the male screw 8, and the male screw 8 receives the pin of the present invention. The nut 10 is formed by screwing.
[0007]
The pin receiving nut 10 has a female screw 12 that is screwed to the male screw 8 on the inner peripheral surface of an annular screwing portion 11, and an outer end on both sides in the diameter direction of the screwing portion 11. L-shaped latching portions 14 each having a standing piece 13 are provided so as to project from each other, and the rotating bracket 15 of the pin receiving nut 10 is latched between the standing piece 13 and the screwing portion 11. A stop recess 16 is provided.
[0008]
Although not particularly limited, it is preferable that a protrusion 17 for retaining the rotating bracket 15 is provided on the upper portion of the peripheral wall of the threaded portion 11 that faces each of the standing pieces 13 constituting the latching portion 14. it is recommended to project the thick portion 18 with.
[0009]
The operation of the pin receiving nut in the temporary work support according to the present invention having the above-described configuration will be described. The small-diameter upper pipe 5 is inserted into the large-diameter lower pipe 3, and the upper pipe 5 is appropriately attached to the lower pipe 3. By lifting and lowering, the overall length of the support 1 is roughly adjusted to the height of the place of use, and in this state, the pin 6 is inserted into a predetermined pin hole 7 located in the long hole 9, and then a pin receiving nut 1 has a diameter that can be hooked to the latching recess 16, such as a bar, a screwdriver, or a steel rod, for example, as shown in FIG. , And the pin receiving nut 10 is rotated by holding the rotating bracket 15 so that the upper edge of the pin receiving nut 10 contacts the lower surface of the pin 6. Touch
[0010]
In this state, when the pin receiving nut 10 is further rotated in the forward direction while holding the rotating metal fitting 15, the pin receiving nut 10 rises, so that the pin 6 is gradually pushed up, and the upper pipe 5 As a result, the overall length of the entire support 1 can be finely adjusted.
[0011]
Further, when the pin receiving nut 10 is rotated in the reverse direction with the rotating metal fitting 15, the pin receiving nut 10 is lowered, so that the upper pipe 5 is its own weight, and the pin 6 is the pin receiving nut. 10 is lowered while being in contact with the support 10, and the entire length of the support 1 can be finely adjusted.
[0012]
In other words, the pin receiving nut 10 in the temporary work support according to the present invention can be used as the rotating metal fitting 15 regardless of the type, as long as it is a metal fitting of a size that can be hooked in the hooking recess 16 by providing the hooking portion 14. it can. Further, before the pin receiving nut 10 comes into contact with the pin 6, the pin receiving nut 10 can simply be held and rotated by hand. Further, if the rotating bracket 15 is of a size that can be hooked below the retaining projection 18, the rotating bracket 15 can be safely removed without being detached from the latching recess 16 during the rotation operation. Rotating work is possible.
[0013]
【The invention's effect】
Since the present invention is as described above, any metal fitting can be used as a rotating metal fitting, so long as it can be hooked into a holding recess without using a special rotating metal fitting. The metal fitting can be easily rotated, which is convenient, and the pin receiving metal fitting can be rotated manually by pressing the latching portion.
