<P>PROBLEM TO BE SOLVED: To provide a device for safely and easily detaching a scaffold ledger plate from a scaffold pipe. <P>SOLUTION: A scaffold pipe and a scaffold ledger plate of a temporary scaffold are fitted and fixed to the scaffold pipe by means of latches that are provided at both the longitudinal ends of the scaffold ledger plate. The latch is provided with a scaffold pipe fitting portion that has an inward round portion and that has a lower portion opened, and also provided with a coming-off prevention mover as a coming-off prevention measure after the fitting of the scaffold pipe. Before dismantlement, since the coming-off prevention mover causes hindrance and makes a one-man operation difficult, a device releases a coming-off prevention function by using the same coming-off prevention mover, folding the coming-off prevention mover into the inside of the round portion of the latch, and applying an anti-slip hollow outside the coming-off prevention mover to the scaffold pipe. <P>COPYRIGHT: (C)2012,JPO&INPIT |
