Construction method for integrally lifting super-high, super-heavy, large-span space corridor
The invention relates to a construction method for integrally lifting a super-high, super-heavy, large-span space corridor. The construction method for integrally lifting the super-high, super-heavy, large-span space corridor comprises the steps that pre-lifting and actual lifting are conducted; steel components are transported on the site in a bulk mode, spliced on fixed points and welded; upper lifting points are arranged on upper chord members of connecting segments between steel trusses and main storied building structures on the two sides, two groups of lifting points are arranged on each trusses, and two hydraulic elevators are arranged on each lifting platform; lower lifting points are arranged at the positions, corresponding to the upper lifting points, of lower chord members of lifting units of the spliced steel trusses, and the working principle that stranded steel wires are used for bearing, a computer is used for controlling and hydraulic synchronous lifting is conducted is adopted. The lifting units of the steel trusses are integrally lifted to the designed elevation and are in butt joint with prearranged parts of the steel trusses, and then installation of the steel trusses is achieved. According to the construction method for integrally lifting the super-high, super-heavy, large-span space corridor, hydraulic lifting is adopted, the amount of aloft work is minimized, time for integral hydraulic lifting is short, and thus the structure installation time can be effectively guaranteed; the lifting weight, the span, the area and the height are not limited by expanding and combining lifting devices.
