To provide a scaffolding connecting device easy in connecting scaffoldings and reduced in construction labor of a building.SOLUTION: A scaffolding connecting device is composed of a drill screw 1, an intermediate member 2 and a joint member 3. The drill screw 1 has a flange 6 and a second screw part 8, and the intermediate member 2 is screwed to the second screw part 8. The joint member 3 is distributably connected to the intermediate member 2 by a bolt 11. By rotating the bolt 11 with a wrench 16, the drill screw 1 is screwed into a structural material 26 of the building. End face cams 18, 19 clutch-likely meshing with each other are formed on the flange 6 of the drill screw 1 and a tip face of the intermediate member 2. When screwing, while surely transmitting torque, the drill screw 1 is not co-rotated when unscrewing the intermediate member 2. Therefore, only the intermediate member 2 can be easily removed. The drill screw 1 functions as a fastening means of a wall material 27.SELECTED DRAWING: Figure 2
【課題】足場の連結は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を提供する。【解決手段】足場つなぎ装置は、ドリルねじ１と中間部材２と継手部材３とで構成されている。ドリルねじ１はフランジ６と第２ねじ部８とを備えており、中間部材２は第２ねじ部８に螺合している。継手部材３は、ボルト１１で中間部材２に組振り可能に連結されている。ボルト１１をレンチ１６で回転することにより、ドリルねじ１が建物の構造材２６にねじ込まれる。ドリルねじ１のフランジ６と中間部材２の先端面とには、クラッチ状に噛み合う端面カム１８，１９が形成されている。ねじ込みに際してはトルクを確実に伝えつつ、中間部材２のねじ戻しに際してドリルねじ１は連れ回転しない。従って、中間部材２だけを簡単に取り外しできる。ドリルねじ１は、壁材２７の締結手段として機能している。【選択図】図２
