To secure the rotation drive of a drill screw in a scaffold connecting device capable of facilitating the assembly of a scaffold and reducing the labor of the construction of a building.SOLUTION: A scaffold connecting device is composed of a drill screw 1, a first nut 2, a second nut 3, and a connecting bolt 4. The drill screw 1 is provided with a flange 8 and an outward male screw part 7, and the first nut 2 is screwed to the outward male screw part 7. The second nut 3 is connected to the first nut 2 by the connecting bolt 4 so as to be assembled. An engaging projection 18 is formed at the tip of the connecting bolt 4, and an engaging hole 19 is formed at the end face of the outward male screw part 7. Since the connecting bolt 4 acts as a wrench, the drill screw 1 can be reliably driven.SELECTED DRAWING: Figure 1
【課題】足場の組み立てが容易でしかも建物の施工の手間を軽減できる足場つなぎ装置において、ドリルねじの回転駆動の確実化を図る。【解決手段】足場つなぎ装置は、ドリルねじ１と第１ナット２と第２ナット３と連結ボルト４とで構成されている。ドリルねじ１はフランジ８と外向き雄ねじ部７とを備えており、第１ナット２は外向き雄ねじ部７に螺合する。第２ナット３は、連結ボルト４で第１ナット２に組振り可能に連結されている。連結ボルト４の先端に係合突起１８を形成して、外向き雄ねじ部７の端面には係合穴１９が形成されている。連結ボルト４がレンチの役割を果たすため、ドリルねじ１を確実に回転駆動できる。【選択図】図１
