Document Type and Number:
WIPO Patent Application WO/2021/120335
Kind Code:
A1
Abstract:
A cumulative lifting method for a large-span unequal-height bidirectional curved surface grid, aiming at solving the problems in the prior art that construction methods commonly used for a large-span space bidirectional curved surface grid require many support measures, have a low construction efficiency and have a high construction cost; and the technical points of the cumulative lifting method lie in comprising the following steps: S1, performing calculation and analysis before construction; S2, performing calculation and control in construction; S3, installing a vertical supporting grid; S4, assembling a bidirectional curved surface grid; S5, providing lifting points; S6, performing cumulative lifting; and S7, installing fittings. The installation method of the present invention provides a compact structure, an industrialized assembly mode, a short installation period, and high operation flexibility.
