STRUCTURE OF TEMPORARY SCAFFOLD AND CONNECTING METAL FITTING USED THEREFOR
To provide a structure of a temporary scaffold capable of constructing another work floor on an upper part by adding a support pipe when necessary without projecting the support pipe upward from the work floor, and a connection metal fitting used for the structure.SOLUTION: In a structure 10 of the temporary scaffold which has a connection fitting 17 connecting a support pipe 12 and an extension support pipe 13 and a horizontal pipe 18 with a wedge mechanism mounted on a hooking fitting 11, the height of the tip of the support pipe 12 is the same as the height of the upper end of the horizontal pipe 18 within an error range of ±2 cm, and insertion parts 14 and 15 of the connection fitting 17 have a lock mechanism 19a provided with projecting pins 21 and 22 oppositely arranged and biased outward by an elastic member 29, respectively; when the insertion parts 14 and 15 are completely mounted on the support pipe 12 and an extension support pipe 13, the projecting pins 21 and 22 are fitted into latching holes 23 and 24 provided to face each other at intermediate positions of the support pipe 12 and the extension support pipe 13.SELECTED DRAWING: Figure 1
【課題】支柱パイプが作業床から上方に突出しないで、しかも必要な場合は、支柱パイプを継ぎ足して更に上部に別の作業床を構築可能な仮設足場の構造及びこれに用いる連結金具を提供する。【解決手段】支柱パイプ１２と延長支柱パイプ１３とを繋ぐ連結金具１７と、掛止金具１１に装着される楔機構付き水平パイプ１８とを有する仮設足場の構造１０であって、支柱パイプ１２の先端高さは水平パイプ１８の上端高さと±２ｃｍの誤差範囲で同一となって、連結金具１７の差し込み部１４、１５はそれぞれ弾性部材２９によって外側に付勢される対向配置された突出ピン２１、２２を備えたロック機構１９ａを有し、差し込み部１４、１５を支柱パイプ１２及び延長支柱パイプ１３に完全装着した場合には支柱パイプ１２及び延長支柱パイプ１３の途中位置に対向して設けられた掛止孔２３、２４に突出ピン２１、２２が嵌入する。【選択図】 図１
