Upside-down construction method for large-span ultra-high signal-layer cylindrical architectural steel structure
The invention discloses an upside-down construction method for a large-span ultra-high signal-layer cylindrical architectural steel structure. The upside-down construction method comprises following steps: firstly, assembling a steel structure with the top having 60 meters and an attached light steel structure enclosure at the elevation height of zero meter in the horizontal position on site, installing lifting tool structures right in place and determining number and positions of arranged tool systems and connected with a main steel structure temporarily, vertically lifting the steel structure with the top having 60 meters and the attached light steel structure enclosure, installing an internal steel structure, successively performing subsequent lifting operation in accordance with the above programs till the pre-determined lifting height is achieved and installation is finished, detaching the lifting tool structures and carrying out rod-supplementing operation at lifting tool positions, and installing a light steel structure enclosure at the elevation height of 60 meters and below. The upside-down construction method for the large-span ultra-high signal-layer cylindrical architectural steel structure has following beneficial effects: wind-resistant control technology for installation of a super-altitude light steel structure enclosure is realized; the problem that the lifting height of a conventional large lifting construction machine cannot satisfy the capability for the lifting requirement is solved; and the light steel structure enclosure at the elevation height of above 60 meters is installed.
