Upside-down construction method for large-span ultra-high signal-layer cylindrical architectural steel structure

Abstract

The invention discloses an upside-down construction method for a large-span ultra-high signal-layer cylindrical architectural steel structure. The upside-down construction method comprises following steps: firstly, assembling a steel structure with the top having 60 meters and an attached light steel structure enclosure at the elevation height of zero meter in the horizontal position on site, installing lifting tool structures right in place and determining number and positions of arranged tool systems and connected with a main steel structure temporarily, vertically lifting the steel structure with the top having 60 meters and the attached light steel structure enclosure, installing an internal steel structure, successively performing subsequent lifting operation in accordance with the above programs till the pre-determined lifting height is achieved and installation is finished, detaching the lifting tool structures and carrying out rod-supplementing operation at lifting tool positions, and installing a light steel structure enclosure at the elevation height of 60 meters and below. The upside-down construction method for the large-span ultra-high signal-layer cylindrical architectural steel structure has following beneficial effects: wind-resistant control technology for installation of a super-altitude light steel structure enclosure is realized; the problem that the lifting height of a conventional large lifting construction machine cannot satisfy the capability for the lifting requirement is solved; and the light steel structure enclosure at the elevation height of above 60 meters is installed.

Description

technical field [0001] The invention relates to the field of steel structure construction engineering, in particular to an inversion construction method for a large-span ultra-high single-layer cylindrical building steel structure. Background technique [0002] With the development of society and the advancement of technology, super-large equipment and instruments have appeared. The production, assembly and maintenance of these ultra-large equipment and instruments need to be operated in large-span and super-high space workshops, so large-span and super-high space workshops began to emerge one after another. [0003] At present, the construction technology of large-span and super-high space workshops is limited by many large-scale lifting construction machinery, such as: 1. There are few or no large-scale lifting machinery equipment rental markets; 2. Even if super-large construction equipment is used, construction costs will be incurred Larger; 3. For the light-weight stee...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-span ultra-high single-layer cylindrical building steel structure flip-chip construction method to address the many shortcomings of the prior art. By providing a new installation process for large-span ultra-high single-layer cylindrical steel structures, Solve the windproof control technology for the installation of ultra-high-altitude light-weight steel structure enclosures, and effectively solve the problem that the hoisting height of existing large-scale crane construction machinery cannot meet the hoisting requirements, and solve the installation of ultra-high-altitude light-weight steel structure enclosures above 80 meters
