Description

本発明は足場の鋼製布板横ずれ防止金具に関するものである。The present invention relates to a steel cloth board lateral slip prevention fitting for a scaffold.

従来の仮設足場の作業床の床材間の隙間は労働安全衛生規則で3cm以下にする様に決められているが、建枠の作業床に最初2枚の鋼製布板の隙間を3cm以下に敷いていても作業床で作業を行い大勢の人が作業床を動きまわる事により徐々に鋼製布板が横ずれして隙間が3cm以上になってその隙間に足を入れてしまい危険であった。The gap between floor materials on the work floor of a conventional temporary scaffold is determined by the occupational safety and health regulations to be 3 cm or less, but the gap between the first two steel cloth boards on the work floor of the building frame is 3 cm or less. Even if it is laid on the floor, it is dangerous to work on the work floor and move a large number of people around the work floor. It was.

従来は次のような欠点があった。
鋼製布板がずれないように隣り合う鋼製布板のつめ金具を番線で縛って固定して鋼製布板の横ずれを防止していたが、その作業を行うには番線を鋼製布板のつめ金具の隙間に通して番線を締める必要があったが、それは手作業となり作業能率が悪く、番線も使い捨てとなっていた。
本発明は、以上のような従来の欠点を鑑み、J字形布板横ずれ防止金具を提供して作業効率の向上と繰返し使用できる事によるコストダウンを目的としている。
Conventionally, there are the following drawbacks.
To prevent the steel cloth board from slipping, the claws on the adjacent steel cloth boards were tied and fixed with a wire to prevent the lateral displacement of the steel cloth board. Although it was necessary to pass through the gap between the claws on the plate and tighten the wire, it was a manual operation and the work efficiency was poor, and the wire was also disposable.
SUMMARY OF THE INVENTION In view of the above-described conventional drawbacks, the present invention aims to provide a J-shaped cloth board lateral displacement prevention metal fitting to improve work efficiency and reduce costs by being able to be used repeatedly.

上記目的を達成するために、本発明はコッタボルトを雄ネジ側が長い符号1のJ字形に曲げたコッタボルトとし、コッタボルトの符号3の雄ネジ側にはボルト部分が通る事が可能で符号4の六角ナットは通る事が出来ない符号6の楕円形の穴、コッタ部分側には符号5の六角形のコッタ部分は通る事が可能な大きな穴と通る事が出来ない小さい穴が重なりあって符号7の雪ダルマ形の穴がJ字形コッタボルトの両端の位置にくる平面的には長方形で、横から見ると雄ネジが前後に移動出来る楕円形の穴部分はフラットで建枠の横架材に当った部分から横架材の頂点までは横架材の外径に沿った円形に曲がり頂点から再びフラットになる符号2の長辺方向にリブ補強された平鋼板形状を特徴とし、J字形に曲げたコッタボルトを建枠横架材に差込んで長い方の雄ネジ部分をリブ補強された平鋼板の楕円形の穴に、六角形のコッタ部分はダルマ形の大きい方の穴に入れてからリブ補強された平鋼板をダルマ形の小さい穴の方にずらし、六角形のコッタ部分が抜けない様にしてから、雄ネジ側の六角ナットを締付ける事によって、J字形ボルトと平鋼板に力が伝わって、建枠の横架材にJ字形布板横ずれ防止金具が固定され鋼製布板のつめ金具がJ字形布板横ずれ防止金具に当たって鋼製布板をずれないようする機能を有するJ字形布板横ずれ防止金具を構成している。In order to achieve the above object, according to the present invention, the cotter bolt is a cotter bolt that is bent into a J-shape with a long male screw side and is a J. Nut cannot pass through the oval hole 6 and the cotter part has a hexagonal cotter part 5 through which a large hole can pass and a small hole that cannot pass through 7 In the plan view, the snow dharma-shaped holes are rectangular at the ends of the J-shaped cotter bolt, and the oval hole where the male screw can move back and forth when viewed from the side is flat and hits the horizontal frame of the building frame. It is characterized by a flat steel plate shape with rib reinforcement in the long side direction of No. 2 that bends in a circle along the outer diameter of the horizontal member from the raised part to the apex of the horizontal member and flattenes again from the apex, bent into a J shape Difference between the cotter bolt and the building frame The longer male screw part is inserted into the elliptical hole of the flat steel plate with rib reinforcement, the hexagonal cotter part is inserted into the larger hole of the Dalma shape, and then the flat steel plate with rib reinforcement is put into the small hole of the Dalma shape. After moving the hexagonal cotter part so that the hexagonal cotter part does not come off, tightening the hexagonal nut on the male screw side transmits the force to the J-shaped bolt and the flat steel plate, and the J-shaped on the horizontal frame of the building frame The cloth board lateral slip prevention metal fitting is fixed, and the steel metal cloth claws are made to hit the J-shaped cloth board lateral displacement prevention metal fitting to constitute a J-shaped cloth board lateral displacement prevention metal fitting.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。
(1)J字形布板横ずれ防止金具の構成部材がリブ補強された平鋼板とJ字形に曲げたコッタボルトを採用した事により、金具の軽量化になっている。
(2)従来の番線を切断し鋼製布板のつめ金具の隙間を通して番線を締める熟練工による手作業がなくなり、足場の鋼製布板横ずれ防止金具を鋼製布板のつめ金具の外側に設置して六角ボルトを電動工具で締付けて鋼製布板の横ずれを阻止するので経験の浅い作業員でも簡単に作業が出来る。
(3)J字形布板横ずれ防止金具の着脱が出来るので、番線のように現場での加工が不要で使い捨てもなく繰返し使用できる。
As is clear from the above description, the present invention has the following effects.
(1) The component of the J-shaped cloth board lateral slip prevention metal fitting employs a flat steel plate reinforced with ribs and a cotter bolt bent into a J shape, thereby reducing the weight of the metal fitting.
(2) The traditional work of cutting the conventional wire and cutting the wire through the gap between the claws on the steel cloth board is eliminated, and the steel cloth board lateral slip prevention fitting for the scaffold is installed outside the claws on the steel cloth board. The hexagon bolts are tightened with an electric tool to prevent the lateral displacement of the steel cloth board, so even inexperienced workers can easily work.
(3) Since the J-shaped cloth board lateral slip prevention metal fitting can be attached and detached, it is not necessary to perform on-site processing like a wire and can be used repeatedly without being disposable.
