WORK SCAFFOLD OF STEEL TOWER
To provide a work scaffold of a steel tower capable of being fixed to a cross arm to be supported without a cross arm at an upper part, by forming a work scaffold using a tensioned wire ladder in an L-shape, fixing a jig to a side face of a cross arm, and connecting a tip portion of a tensioned wire ladder and an upper end portion of a post.SOLUTION: A work scaffold A bridged when performing maintenance and inspection of an insulator string E and a power transmission line D near a tip portion of a cross arm C of a steel tower B comprises: a jig 1 detachably fixed to the cross arm C; and a tensioned wire ladder 10 whose base end is detachably fixed to the jig 1 and whose tip portion protrudes below the power transmission line D and the insulator string E. The jig 1 comprises two posts 2 provided with an interval and fixed by a plurality of cross rails. The post 2 of the jig 1 is fixed to a cross arm main material and a cross arm hanging material at a side face of the cross arm C. A branch line is tensioned from the tip portion of the tensioned wire ladder 10 whose base end is fixed to the jig 1 to an upper end portion of the jig 1. A branch line is tensioned from the upper end portion of the jig 1 to a member at the other side face of the cross arm C.SELECTED DRAWING: Figure 1
【課題】作業用足場を緊線はしごと治具によってＬ字状に形成し、治具を腕金の側面に固定し、緊線はしごの先端部と支柱の上端部を支線で接続して支持し、上方に腕金が無くても、腕金に支持固定出来る、鉄塔の作業用足場を提供する。【解決手段】鉄塔Ｂの腕金Ｃの先端部付近の碍子連Ｅ、送電線Ｄを保守点検する際に架設する作業用足場Ａにおいて、作業用足場Ａは、腕金Ｃに着脱自在に固定する治具１と、治具１に基端を着脱自在に固定し、先端部を送電線Ｄや碍子連Ｅの下方に突出する緊線はしご１０から成り、治具１は間隔をあけて設けた２本の支柱２を複数の横桟で固定して成り、治具１の支柱２を腕金Ｃの側面の腕金主材と腕金吊材に固定し、治具１に基端を固定した緊線はしご１０の先端部から治具１の上端部に支線を張り、治具１の上端部から腕金Ｃの他方の側面の部材に支線を張った。【選択図】図１
