Example Embodiment

[0066] Example 1: Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Picture 8 , Picture 9 , Picture 10 with Picture 11 As shown, the installation method of the computer-controlled external expansion and accumulative lifting of the ultra-high arched grid structure is carried out according to the following steps:

[0067] (1) Calculation and analysis before rotation:

[0068] Use calculation software to calculate and analyze the whole construction process to ensure that the structure itself and the lifting system can meet the relevant mechanical and structural requirements during the construction process, and ensure that the construction process is safe and controllable;

[0069] (4) Calculation control during construction:

[0070] The hydraulic lifting construction requires high synchronization control. The computer synchronization control system is adopted during the construction process, and the monitoring during the lifting process is stre...

Abstract

The invention relates to a method of erection, in particular to a computer-controlled expansion accumulative lifting method for erecting a super-high arch grid structure, and belongs to the field of steel structures. The method includes the steps of pre-construction computational analysis, under-construction computational control, preparation before unit grid lifting, selection of a hoisting mode, selection of hoisting site conditions, supporting with temporary members of unit grids, staged hoisting, and installation of accessories. The method has the advantages that the structure is compact, the assembly mode is industrialized, the erection period is short, and operational flexibility is high.
