In addition, it is possible to increase the load resistance and improve the safety and to expand the working range for the single lifting unit T. In this case, the vertical frame members 1 are stacked on each other. Since it consists of a plurality of frame members 2 that are freely decomposable, it is possible to carry and transport more easily by separating the plurality of frame members 2 into a single frame member 2 and to reduce the number of frame members 2. By selecting, it can be set as the vertical frame member 1 of the appropriate length according to the working height of the building K, and the versatility of use can be improved.

Even in the second embodiment, the same operational effects as the first embodiment can be obtained, and the working range on the scaffold member 23 can be expanded, and the scaffold member 23 is composed of the fixed scaffold member 24 and Since it is composed of the extendable scaffold member 26, the length can be set appropriately according to the work range of the building K, and the work efficiency can be improved.
[0024]
The third embodiment shown in FIGS. 9 and 10 shows another example structure applied to a vertical hole-shaped part of a building. In this case, two sets of the lift units T of the first embodiment are addressed in parallel to each opposing wall M, A total of four sets are arranged, that is, two sets of the scaffold device of the first embodiment are arranged on each wall surface M, and at this time, a gap allowing movement of each moving member 9 is provided between each scaffold member 23 and each scaffold. The bridging member 27a is fixed between the members 23 and fixed to only one of the scaffold members 23, thereby allowing the moving member 9 to move.
