場合も安全である。As described above, the method for constructing a tower according to the present invention provides a method for assembling a tower provided in an upper part of a space for assembling the tower in a frame of an assembled building which is provided immediately below the installation position of the tower. Since the construction work of the tower is performed at the work place, the work such as assembling, finishing, and painting of the tower can be performed in low places, and it is safe. Work without being affected by
Since the part of the tower that goes out of the building is a completed part, there is no danger of falling objects and it is safe to construct in urban areas.
