Integral lifting construction method for hanging and assembling spherical net rack
The invention discloses an integral lifting construction method for hanging and assembling a spherical net rack, and belongs to the technical field of net rack structure construction. The method comprises the following steps of: 1, establishing a finite element analysis model of the grid structure by applying Midas/Gen finite element analysis software according to the composition form of the spherical grid structure; 2, according to the analysis and verification result in the step 1, dividing the splicing and lifting stage or lifting height of the spherical grid structure in combination with the actual space size of the structure; 3, arranging a lifting platform and a lifting hanging point, and a hydraulic synchronous lifting system is installed; 4, after each lifting height is increased,repeating the assembling process of the next lifting unit in the step 2 and the lifting process of the next lifting unit in the step 3; 5, continuously lifting the whole ball structure assembled in the step 4 to the position 100-200 mm away from the designed elevation; and 6, performing step-by-step unloading of the hydraulic lifting system. The spherical structure is adopted for segmented assembly and overall lifting, the construction speed is high, and safety and reliability are achieved.
