METHOD FOR LAYER-BY-LAYER CUMULATIVE AND SYNCHRONOUS LIFTING CONSTRUCTION OF WAVY SPECIAL-SHAPED STEEL STRUCTURE CANOPY

The present disclosure discloses a method for layer-by-layer cumulative and synchronous lifting construction of a wavy special-shaped steel structure canopy. In the present disclosure, layered assembly and layer-by-layer hydraulic cumulative lifting are adopted: through structural analysis, a third structural floor, a fourth structural floor, and a fifth structural floor have large-area floor slabs, which can be used as assembly sites for steel structures, welding of the steel structures is completed by layer-by-layer upward lifting, and with this solution, a lifting height of the steel structures can be reduced from 36.62 m to 14.4 m. Assembly, welding, painting and other main operations of the steel structures are performed on the floors to minimize the amount of high-altitude work; hydraulic synchronous lifting equipment and facilities are small in size, low in weight, high in mobility, and convenient to install and remove; and temporary facilities such as lifting brackets and platforms can use existing structures such as steel supporting columns, so that the quantity of the temporary facilities is reduced, and high economic benefits are achieved.
