Problems solved by technology
However, it is not feasible for projects that require overall hoisting
For example, if the steel structure is as high as four floors, and the weight of the device is heavy, it is difficult to find the hoisting equipment, and the site requirements are high, and the traffic is not allowed to be interrupted for construction on site; if the single-piece installation method of multi-layer steel structure is used: the overall stability is poor, and the installation requirements In addition, it is necessary to change the design according to the installation again, the safety risk is high, and the deflection and axis are difficult to control
[0003] Therefore, there are above-mentioned inconveniences and problems in the single-piece installation method of the known single-layer steel structure.

A multi-tier large-span steel structure mounting method is used for mounting a four-tier steel structure comprising a first tier structure, a second tier structure, a third tier structure and a fourth tier structure. A mounting process includes: surveying and setting out for the mounting of the steel structure; setting out for a support foundation; constructing the support foundation; positioning and setting out for positions of corridor steel columns; hoisting the corridor steel columns; mounting steel column supports on the support foundation; mounting the first tier structure; mounting the second tier structure; mounting the third tier structure; mounting the fourth tier structure; mounting inter-tier link beams; mounting cornice steel beams; welding; removing the steel column supports. The method is characterized by including the steps of a, mounting the first tier structure; b, mounting the second tier structure; c, mounting the third tier structure; d, mounting the fourth tier structure. The multi-tier large-span steel structure mounting method has the advantages that the requirements on mounting sites are greatly lowered and engineering cost is decreased by 20%.
Description
technical field [0001] The invention relates to a steel structure installation method, in particular to a multi-layer long-span steel structure installation method. Background technique [0002] In the past 10 years, long-span steel structures have been widely used in China, and the common ones are truss, suspension cable structure, and thin shell structure. Long-span single-story steel structures have been promoted in China as new energy-saving buildings. Conventional steel structures are single-story, even if they are multi-story, they are also office buildings, etc., with relatively small spans and no major equipment installation requirements. The installation and construction technology of long-span single-story steel structures common in China has become mature. For large-span steel structures such as workshops, overall hoisting or double-machine high-altitude splicing is used. For multi-layer steel structures, due to the small size and light weight of the installatio...
