SCAFFOLD TREAD BOARD DEVICE FOR CIRCULAR SKELETON
To provide a scaffold tread board device for a circular skeleton which does not require a fixing work for preventing falling off due to a blow-up, and which contributes economically by utilizing an existing tread board structure.SOLUTION: A scaffolding tread board device for a circular skeleton, in which scaffolding tread boards are installed horizontally on horizontal rods P of building frame that are spaced apart from each other in a circular shape, comprises: first tread boards 1 each of which is continuously provided with a rectangular tread board body and step boards with cross-sectionally-C-shaped mounting grip fittings K1X to K4X protrusively provided at both side parts of end faces; second tread boards 2 each of which is continuously provided with a rectangular tread board body and step boards with mounting grip ribs protrusively provided at both side parts of end faces; and third tread boards 3 each of which is continuously provided with a rectangular tread board body and step boards formed with a notched part at a corner of one of end faces as well as mounting grip ribs protrusively provided at both side parts of the end faces.SELECTED DRAWING: Figure 1
【課題】吹上による脱落防止のための固定作業を要することがなく、かつ、既存の踏板構造を利用する経済的に資する円形躯体用足場用踏板装置を提供する。【解決手段】円形状に離間配置される建枠の水平杆Ｐに足場用踏板を水平状態で架設する円形躯体用足場用踏板装置において、矩形状踏板本体と、端面の両側部に断面形状Ｃ字状の架設用つかみ金具Ｋ１Ｘ〜Ｋ４Ｘを突設するステップ板とが連設される第一踏板１と、矩形状踏板本体と、端面の両側部に架設用つかみリブを突設するステップ板とが連設される第二踏板２と、矩形状踏板本体と、端面の片方の隅部に切欠部を形成すると共に当該端面の両側部に架設用つかみリブを突設するステップ板とが連設される第三踏板３、とからなる。【選択図】図１
