Construction method of large-weight ship-shaped daylighting roof steel structure

A construction method of a large-weight ship-shaped daylighting roof steel structure comprises the steps that S1, a carcass frame is erected in the air on the site ground, and a carcass component matched with a ship-shaped steel structure ship body in shape is formed on the upper portion of the carcass frame; s2, a full-hall supporting scaffold is erected below the daylighting roof and around the carcass frame; s3, an upper ring beam is welded and assembled on the upper portion of the carcass frame through a lifting tool; mounting an upper ring beam inhaul cable and tensioning the upper ring beam inhaul cable; s4, mounting and welding of the ship-shaped steel structure and the daylighting roof are completed in a partitioned mode, and after mounting and welding are completed, daylighting roof inhaul cables are mounted and tensioned; s5, welding installation of all components of the steel structure is completed, and full-load tensioning anchoring is conducted on the inhaul cable after acceptance inspection is q
