Moreover, the assembly and dismantling work can be facilitated as compared with the conventional one, and the work cost can be reduced. In addition, the installation mechanism 1 can be engaged with and disengageably engaged with the base plate member B laid on the ground M on which the base frame 1 is to be installed, and the base plate member B and the installation base frame 1 are integrally connected. As a result, the floor plate member B acts as a stabilizing member, which can suppress the need to intentionally incorporate an outrigger mechanism, can stably support the entire device, and improve safety accordingly. In addition to the fact that the floor plate member B is installed and the installation frame 1 is installed on the floor plate member B at most of the work sites, it is not necessary to carry in and carry out the floor plate member B to the site, and only that site transportation It is easy to move and the workability can be improved accordingly.

Further, in this case, since the scaffolding member 24 is provided so as to be able to extend and contract, as shown in the state of FIG. 1 to the state of FIG.
The length can be appropriately set according to the work range of the building N, the work efficiency can be improved, and in this case, the main frame member 4 can be stacked and disassembled into a plurality of frame members 5. Therefore, by separating the plurality of frame members 5 into a single frame member 5, transportation and transportation can be performed more easily, and by selecting the number of frame members 5, the working height of the building N can be increased. The main frame member 4 having an appropriate length according to
Greater versatility of use.

The present invention is not limited to the above-described embodiments, but 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. It is a thing.

[0019]

As described above, according to the present invention, the height of the scaffolding member can be set to an arbitrary height according to the work site of the building by raising and lowering the raising and lowering member. Moreover, the scaffolding member can be installed at any desired front and back position by moving the moving member forward and backward, and the gap between the scaffolding member and the outer wall can be made as small as possible to improve safety and work It is easy to improve the work efficiency, and the assembly and disassembly work is easier than before, and the work cost can be reduced, especially on the ground where the installation frame should be installed. It is possible to engage and disengage the laid plate member by a locking mechanism.
