Is configured to allow.

Reference numeral 37 denotes a lock mechanism which is provided between the main frame member 4 and the elevating member 6 and has a structure for fixing the elevating member 6 at an arbitrary stop position.

Since this embodiment has the above configuration,
For example, it is transported to a construction site or the like in a state where it is disassembled into the installation frame 1, the main frame member 4 and the scaffold member 24. In this case, the main frame member 4 is disassembled into a plurality of frame members 5 and the scaffold member 24 is disassembled. Is disassembled into the fixed scaffolding frame 26, the telescopic scaffolding frame 28, the auxiliary scaffolding frame 34, and the handrail frame 36, and is carried in. The mounting frame 1 is fixed to the floor plate B installed at a predetermined position by the locking mechanism 2, and Installation frame 1, main frame member 4, and scaffold member 24

And moving the moving member 11 in the front-rear direction by the rotation of the rotating shaft 15, disposing the moving member 11 close to the building N,
In accordance with the work height, the work at a high place is performed on the scaffold member 24 while moving the lifting member 6 and the moving member 11 up and down and moving.

Thus, the height of the scaffold member 24 can be set at an arbitrary height in accordance with the work site of the building N by raising and lowering the elevating member 6, and furthermore, the height of the scaffold member 24 can be set at an arbitrary front and rear position by moving the moving member 11 back and forth. The scaffold member 24 can be installed. For this reason, for example, in the case of the outer wall construction of the building N, even if the eaves portion or the protrusion portion of the roof is present, the outer wall is located at a position where the moving member 11 is not obstructed. The moving member 11 can be moved closer to the outer wall after being raised and lowered in a state where the moving member 11 is separated from the outer wall, the gap between the scaffold member 24 and the outer wall can be made as small as possible, and safety can be improved. The work becomes easier and the work efficiency can be improved, and the assembling and disassembling work can be made easier and the work cost can be reduced as compared with the related art. In addition, the mounting plate frame 1 can be detachably locked to the floor plate member B laid on the ground M on which the mounting base frame 1 is to be mounted by the locking mechanism 2, and the floor plate member B and the mounting base frame 1 are integrally connected. Then, the floor plate member B acts as a stabilizing member, so that it is possible to suppress the necessity of incorporating the outrigger mechanism, and it is possible to stably support the entire apparatus, thereby improving safety. At the work site, the floor plate member B is mostly installed, and the installation frame 1 is installed on the floor plate member B. Therefore, it is not necessary to transport and unload the floor plate member B to and from the site. Movement becomes easy, and workability can be improved accordingly.

In this case, since the scaffold member 24 is provided so as to be extendable and contractible, the state shown in FIG.
The length can be appropriately set according to the working range of the building N, and the working efficiency can be improved. In this case, the main frame member 4 is composed of a plurality of frame members 5 that can be stacked and disassembled from each other. Therefore, the transportation can be performed more easily by separating the plurality of frame members 5 into a single frame member 5, and the working height of the building N can be increased by selecting the number of the frame members 5. The main frame member 4 having an appropriate length in accordance with
The flexibility of use can be increased.

The present invention is not limited to the above-described embodiment. For example, the structures of the main frame member 4, the elevating member 6, the moving member 11, the locking mechanism 2 and the like are appropriately designed and changed. Things.
