<P>PROBLEM TO BE SOLVED: To reduce time and cost by reducing man-hours in constructing a temporary scaffold for use in various operations for structures. <P>SOLUTION: A temporary scaffold structure comprises a pair of vertical frames 6 suspended from both ends of a suspending beam 5 and horizontal frames 7 bridging between the vertical frames 6. Each of the vertical frames 6 is composed of a plurality of vertically aligned link members 8 turnably connected with each other, and turning connection parts 9 of the link members 8 are mutually connected with every other ones via the horizontal frame 7. When the suspending beam 5 is lowered, the vertical frames 6 are folded in a bellows-like manner, and when the suspending beam 5 is raised, the vertical frames 6 are linearly extended. <P>COPYRIGHT: (C)2012,JPO&INPIT |
