Description of the Related Art Conventionally, joint processing of an outer wall in an upper floor portion of a building, assembling work of an eaves ceiling, and the like have been performed on a scaffold provided along the outer wall of the building. At this time, since the building is formed in a plane square shape and the scaffold is provided close to the outer wall, the worker can work on the upper floor part in the same way as working on the lower floor part. it can.

[0003]

However, if an overhanging portion is formed on the lower floor of the building, the scaffold must be installed along the outer wall of the overhang. For this reason, the distance between the scaffold and the outer wall above the overhanging portion becomes large, and there is a problem that construction work or the like on the outer wall above the overhanging portion cannot be performed.
At this time, it is conceivable to install the scaffold plate overhanging the building side rather than the pillars forming the scaffold. However, since the scaffold plate is cantilevered, even if the distance between the pillars is within 1800 mm, the scaffold plate may be provided. Can be extended only about 400 mm from the pillar to the building side, and when the overhang amount of the overhang portion is large, there is a problem that construction work of the outer wall above the overhang portion cannot be performed. A first object of the present invention is to
An object of the present invention is to provide a work scaffold capable of easily performing a construction work on an overhanging portion of a building.

Further, since the widths of the overhang portions are formed in various sizes depending on the building, a scaffold that can be commonly applied to each overhang portion having such a different size is required. A second object of the present invention is to provide a working scaffold that can be commonly applied to overhangs of various widths in each building.

[0005]

A working scaffold according to claim 1 of the present invention will be described with reference to the drawings.
