A large span ultrahigh section steel framework segmented hoisting construction method comprising the following steps: flowing main structure construction, and pre-burying foundation bolts; segmentally mounting a section steel column; inspecting the main concrete structure before hoisting; setting out a section steel column mount axis control line and a section steel column mount elevation control line; carrying out rectification after each hoisting step in segmental hoisting, which includes column foot elevation regulation, column foot axis regulation and column body verticality rectification; hoisting section steel girders, using temporary bolts for fastening same, and finally carrying out high intensity bolt connection and welding. The invention provides a reasonable construction method for hoisting the large span ultrahigh section steel framework; pre-install preparation, fixing member positioning, and contentious rectification in an install process can ensure the members to have accurate positions; the members are stably connected with high intensity, thus satisfying structure force bearing requirements; the method is simple in hoisting, high in construction efficiency, and can satisfy construction quality requirements.
