High-rise long-span door type truss integral lifting device and construction method thereof

The invention relates to a high-rise long-span door type truss integral lifting device and a construction method thereof. The device comprises a run-through jack, a steel strand and an anchoring structure, wherein the anchoring structure consists of an upper anchoring structure which is fixed on an arranged upper truss bracket and a lower anchoring structure which is fixed on a lifted truss; the run-through jack is fixed on the upper anchoring structure and is symmetric on the two sides of the arranged upper truss bracket; and the run-through jack and the steel strand integrally lift the lifted truss to a position which is flush with the arranged upper truss bracket. A whole-course dynamic stress monitoring mode is adopted for monitoring while the integral lifting is performed by a lifting unit. In auxiliary measures of the method, an operating scaffold for ground assembly and an overhung scaffold at a lifting point position are only required to be erected, so the measures are extremely few; and the integral
