[Problems to be solved by the invention]
Under these circumstances, the present inventors (et al.) Have developed a scaffold for this type of stand-alone tower structure which is highly mobile, can greatly reduce the labor required for temporary construction, dismantling, and removal and can be used repeatedly. We conceived an installation jig (a frame mount for the present invention) and worked hard on development, and as a result, completed the present invention. No prior art relating to the present invention has been found so far.
[0006]
The present invention has been made in view of such circumstances, and solves the above-mentioned problems, and renovates a conventional scaffolding device and a method for installing the same. It provides an installation method.
