In general, there is a lot of risk of safety accidents when constructing high-rise buildings, but one of the most common places is the elevator hoistway. Elevator hoistway is a part where workers lose their precious lives in one trip because they make a hole from the floor to the upper floor not only during the construction of the concrete wall but also after the construction of the concrete wall until the elevator is installed. It is urgently required to stably proceed not only the general work performed inside the elevator hoistway, but also the concrete wall work.

As related prior art, Registered Utility Model No. 20-0489367 "Workbench for Elevator Elevator Passage Construction" (hereinafter referred to as 'Prior Art 1'), Patent Publication No. 10-2010-0123012 "Building Scaffolding" (hereinafter referred to as ' 'Prior art 2'), Patent Registration No. 10-0140904 "scaffolding for elevator pits" (hereinafter referred to as 'prior art 3').
