SCAFFOLD STRUCTURE FOR CONSTRUCTION MACHINE
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
【課題】足場部材の着脱作業を容易に行うことができ、過大な負荷が作用しても足場部材が取り外せなくなるおそれのない建設機械の足場構造を提供する。【解決手段】足場ブラケット４０と支持ブラケット５０の上側係合部７０，８０は、一方が前後方向に延びる上側軸部５２、他方が凹部８１であり、上側係合部７０を上側係合部８０に上方から引っ掛けると、上側軸部が上側凹部に嵌まることによって足場ブラケット４０が支持ブラケット５０に上側軸部５２の軸心回りに回動可能に支持される上側係合状態となる。足場ブラケット４０と支持ブラケット５０の下側係合部７５，８５は、上側係合部７０，８０が上側係合状態にあるときに、足場ブラケット４０を上側軸部５２の軸心Ｘ回りに第１の方向に回動させると、下側係合部７５が下側係合部８５に当接して足場ブラケット４０の第１の方向への回動と上方への移動とが規制される下側係合状態となる。【選択図】図６
