Problems solved by technology

[0004] Therefore, the disadvantage of the prior art is that the weight of the assembled large steel structure is greatly restricted, and there needs to be a comparatively open place around the location, so that the truck crane etc. can normally drive away after the lifting operation.

Abstract

The invention discloses a large steel structure positioning method that comprises the following steps: determining two groups of stress points of the large steel structure; determining the model of the jacking device; lightering the large steel structure arranged on the segmented platform to a designated place by using a flat car; mounting a first group of jacking devices at one group of stress points of the large-scale steel structure to support the large-scale steel structure; moving the flat car and the segmented platform away; mounting a second group of jacking devices at the other group of stress points of the large steel structure; and adjusting the jacking heights of the first set of jacking devices and the second set of jacking devices alternately so that the large steel structure can fall on the ground. According to the invention, the hoisting capacity of a large steel structure in a landing site does not need to be considered, the steel structure can be made as large as possible when the steel structure is manufactured, the follow-up splicing and assembling work is reduced, and the requirement for the size of the site space of the landing site does not exist.

Description

technical field [0001] The invention relates to the technical field of steel structure installation, in particular to a positioning method for a large steel structure. Background technique [0002] At present, when modern steel structures are manufactured, they are generally prefabricated and assembled in a relatively concentrated place, where the crane resources, kinetic energy and other supporting facilities are usually relatively abundant, and because the steel structure is assembled from raw material parts , so it has a longer production cycle. [0003] After being assembled into a larger steel structure, the steel structure is usually transported to the designated place by flatbed truck (or rail trolley, modular trolley, etc.), because these designated places usually do not have large lifting equipment (such as high crane, gantry crane, etc.), Only mobile crane resources such as truck cranes can be used for hoisting, and the hoisting tonnage of truck cranes is limited....
