However, according to the conventional grounding type scaffolding device, it is very difficult to move the ground when the ground is not leveled (usually, the ground is often unleveled at the outer wall construction stage). ), There is a problem that it cannot be used unless it is on a finished floor surface such as asphalt or concrete. Moreover, since the conventional scaffolding device is a push-pull type,
Not only is the width and height of the device limited by the payload capacity, but there is also the inconvenience that the load of personnel, materials, tools, etc. is limited.

Therefore, an object of the present invention is to construct a scaffold of a self-propelled type so that the scaffold can be installed without being restricted by the ground condition, size, and load, and can be easily moved to a required construction site. , To provide a new mobile scaffolding device capable of efficiently performing wall construction.

[0005]

In order to solve the above-mentioned problems, the mobile scaffolding device of the present invention has rails laid on the roof of a building, and supports a self-propelled platform equipped with wheels and motors on the rails. , A pillar extending along the wall surface of the building is hung on the self-propelled base, a mounting table is provided at the lower end of the pillar, a frame scaffold is mounted on the mounting table, and the wall surface of the building abuts in the vicinity of the mounting table. It is configured by arranging rollers.

[0006]

According to the mobile scaffolding device of the present invention, the self-propelled platform is driven by the motor along the rails of the roof, the mounting platform is horizontally guided by the rollers along the wall surface, and the frame scaffold is required in the vertical state. Moved to the construction site. Therefore,
The scaffolding device can be used safely without any trouble even on a site where the ground is not leveled. Further, since it is configured to be self-propelled, the width, height, and loading load of the device can be set large, and the work efficiency can be greatly improved.
