2. Description of the Related Art Scaffolds in construction and civil engineering work occupy an important factor in the progress of construction work, and how to build scaffolds is a key to safe and smooth construction. Therefore, in the field of construction, a method such as surrounding the building with a solid scaffolding frame has been adopted, and measures to prevent falling objects by covering a safety net around the scaffolding frame have been adopted. However, it is no exaggeration to say that scaffolding frames are relatively neglected in the field of civil engineering.

[0003] That is, as shown in FIG. 11, a conventional scaffold for civil works is constructed by sequentially projecting a stage 7 on a sloped land E and constructing it between columns or piles 1 of H-section steel or the like standing on the site. In order to attach a brace or a cross beam at a predetermined height from the ground, a worker attaches a scaffold plate 5 suspended by a wire rope 4 to a crane 3 of a crane truck 2 arranged on the ground. 6 is mounted to work from one side of the pile 1. This scaffold plate 5 is a simple one in which a plate is stretched over a rectangular frame or the like created at the work site in an emergency, and has no safety fence or any danger prevention equipment.

[0005] Further, since the scaffold plate 5 is below the stage 7 and cannot be seen by a crane operator,
Monitoring personnel for communication or signaling between the crane operator and the worker 6 are required, and even if the scaffold plate 5 is to be moved, the worker 6 cannot perform the desired movement, and does so. Took time.

Further, since the work is performed by shifting the scaffold plate 5 to one side of the pile 1, when work is to be performed on both sides of the pile 1, the scaffold plate 5 is moved up and down and the same work is performed again. Requires twice as much work time.

[0007] In addition, the scaffold plate 5 is prepared on the spot, and cannot be made too large and heavy due to suspension with one wire rope 4.
The work was not able to progress quickly because the space was small and the number of workers and equipment that could be boarded was limited.

As described above, according to the present invention,
The scaffold base plate that can work from both front and rear sides with multiple piles standing on the ground is supported by the pile etc. so that it can be lifted and lowered, so that crane trucks etc. are unnecessary for scaffolding work Needless to say, since it moves up and down with the pile etc. sandwiched, there is little swing with respect to wind pressure, etc., and by making the scaffold base plate an appropriate length, it is possible to secure space for many workers and equipment to be placed, Since the winch is arranged on the scaffold, the operator can arbitrarily raise and lower the gondola.

Moreover, since the scaffold base plate is provided so as to sandwich the pile, etc., it is possible to work safely on both the front and rear sides of the pile, etc., and the structure is such that the suspension support can be moved in the horizontal direction. Can quickly adapt to changes in span.

Further, the following operation and effect can be obtained. Since the stakes are suspended and supported by the temporarily constructed piles, there is no need to suspend the cranes as in the related art, and there is no need to restrain the cranes. The gondola itself can move up and down by itself by moving up and down with the winch. In addition, the worker on the gondola can move up and down by himself.
Therefore, there is no danger that the crane operator who cannot see the gondola operator can perform the lifting / lowering operation as in the case of being suspended by a conventional crane.

Further, work can be performed from both sides of the pile. Further, the load capacity of the gondola can be increased. In other words, conventionally, since it is hung on a crane, the space of the gondola that can be hung from the convenience of handling is limited, and the number of workers and the amount of equipment do not meet the demand, but according to the present invention. In this case, a sufficient load necessary for the work can be suspended. And since it is supported above all by the pile of the temporarily constructed structure, safety devices such as fence guards can be installed without affecting workability, and the safety is high. The gondola can be adjusted in accordance with the span of the pile for suspending and supporting the gondola, and the gondola can be expanded in the lateral direction. Further, by using a gondola having two vertically connected stages, it is possible to simultaneously perform the work of the upper and lower parts of the pile such as the work of connecting the upper and lower parts of the braces at the same time.
