Accumulative lifting method for large-span unequal-height bidirectional curved surface net rack

Abstract

The invention relates to the technical field of net rack construction, in particular to an accumulative lifting method for a large-span unequal-height bidirectional curved surface net rack. The accumulative lifting method aims to solve the problems that in the prior art, a construction method commonly adopted for a large-span space bidirectional curved surface net rack is large in number of invested supporting measures, low in construction efficiency and high in construction cost. The method is technically characterized by comprising the following steps of S1, calculating and analyzing beforeconstruction; S2, calculating and controlling in construction; S3, installing a vertical face supporting net rack; S4, assembling the bidirectional curved surface net rack; S5, setting a lifting point; S6, accumulative lifting; and S7, mounting accessories. The mounting method is compact in structure, short in mounting period and high in operation flexibility, and adopts an industrial assembly mode.

Description

technical field [0001] The invention relates to the technical field of network frame construction, in particular to a cumulative lifting method for large-span and unequal-height two-way curved surface network frames. Background technique [0002] With the continuous emergence of large-span and large-area grid structures, the construction height and span of large-area grid structures continue to increase. Traditional construction methods not only increase construction costs and lengthen construction periods, but also reduce construction safety. Therefore, seeking a safe, fast and low-cost construction method is one of the key points of the current large-area and long-span grid construction research. [0003] The ultra-high arched grid structure is a grid structure with welded ball nodes as the main form, which is suitable for columnar or arched structures with large span, light weight, and reasonable stress. This type of structure is widely used in buildings such as airship ...
