Abstract:
To provide a scaffold structure for a construction machine in which detachment work of a scaffold member can be easily carried out and there is no possibility the scaffold member cannot be removed even when an excessive load is applied.SOLUTION: One of an upper engagement parts 70, 80 of a scaffold bracket 40 and a support bracket 50 is an upper shaft 52 extending in a longitudinal direction, and the other is a recess 81. When the upper engagement part 70 is hooked in the upper engagement part 80 from above, the upper shaft fits in the upper recess to set an upper engagement state where the scaffold bracket 40 is supported on the support bracket 50 so as to be rotatable about an axis of the upper shaft 52. Lower engagement parts 75, 85 of the scaffold bracket 40 and the support bracket 50 are set, when the scaffold bracket 40 is rotated about an axis X of the upper shaft 52 in a first direction while the upper engagement parts 70, 80 are in an upper engagement state, a lower side engagement state where the lower engagement part 75 abuts against the lower engagement part 85 to restrict first-direction rotation and upward movement of the scaffold bracket 40.SELECTED DRAWING: Figure 6
