FALL PREVENTION DEVICE AND FALL PREVENTION METHOD
To secure safety of a worker with simple operation even at a reinforcing bar assembling site without erected columns.SOLUTION: A fall prevention device 100 comprises: an upper flat plate part 10 having a first fastening port 11; a lower flat plate part 20 having a second fastening port 21 at the approximately same position as that of the first fastening port of the upper flat plate part in a state in which the upper flat plate part is made to face the lower flat plate part; a fastening part 30 that is inserted into the first fastening port and the second fastening port in a state in which the upper flat plate part and the lower flat plate part are made to face each other to enable adjustment of a gap between the upper flat plate part and the lower flat plate part; and an approximately cylindrical single tube insertion part 40 that has a bottom face part 43 and an open top face. The fall prevention device also comprises: a female screw part 22 in the vicinity of one end of the lower flat plate part; and a male screw insertion hole 12 on the approximately same position as that of the female screw part in a state in which the lower flat plate part and the upper flat plate part are made to face each other. Part of a male screw part 41 with its head up is fixed to the bottom face part of the single tube insertion part; a tip of the male screw part protrudes downward from the bottom face part.SELECTED DRAWING: Figure 1
【課題】立柱のない鉄筋の組立現場においても簡単な操作で作業者の安全を確保することを課題とする。【解決手段】第１締付口１１を有した上平板部１０と、上平板部を対向させた状態で、上平板部における第１締付口と略同一場所に第２締付口２１を有した下平板部２０と、上平板部と下平板部とを対向させた状態で、第１締付口と第２締付口とに挿入して上平板部と下平板部との間の間隔を調節可能な締付部３０と、底面部４３を有し、天面が開放された略円筒形状の単管挿入部４０と、を備え、下平板部の一方の端部近傍に雌ねじ部２２を有するとともに、下平板部と上平板部とを対向させた状態で、雌ねじ部と略同一場所の上平板部に雄ねじ挿入孔１２を有し、単管挿入部の底面部には、頭を上にした雄ねじ部４１の一部が固定されているとともに、雄ねじ部の先端が底面部から下方に突き出していることを特徴とする転落防止装置１００を用いることとした。【選択図】図１
