<P>PROBLEM TO BE SOLVED: To provide a scaffold which allows other operators to easily go up and down stairs even when temporarily installed at the turn-back part of a U-turn type stairs. <P>SOLUTION: With a scaffold 1 temporarily installed at a turn-back part 21, an operator A riding on a floor part 2 can perform various work above the turn-back part 21. Other operators can go up and down stairs 20 through a turn-back route 15 formed inside a floor supporting part 10. The scaffold 1 is thus prevented from getting in the way even when temporarily installed at the turn-back part 21 of the U-turn type stairs 20, so that the other operators easily go up and down the stairs 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
