Venue giant arch structure high-altitude inclination deflection lifting method

Abstract

The invention discloses a venue giant arch structure high-altitude inclination deflection lifting method, which comprises the following steps that (a) preparation work is done before the giant arch lifting; (b) a third unit of the giant arch is installed and lifted; (c) the third unit of the giant arch is in butt joint with a second unit and a fourth unit; (d) the angles of the three units are regulated; (e) the three units are integrally lifted to the preset designed elevation; (f) a temporary support frame is installed; (g) the three units are merged with the first unit and a fifth unit; (h) after the installation reservation, rod elements are installed, and acceptance checking and coating are carried out for completing the giant arch structure high-altitude inclination deflection lifting. The method provided by the invention has the advantages that the installation and construction difficulty can be effectively reduced, the construction is safe and convenient, the cost is reduced, and in addition, the quality, the safety and the construction period can be respectively and effectively ensured.

Description

Technical field: [0001] The invention relates to a construction method, in particular to a high-altitude oblique deflection lifting method for a giant arch structure of a venue. Background technique: [0002] At present, for the hoisting method of large-scale arched structures, it is generally necessary to build a large-scale support system first, and use a large-scale hoisting machine to lift each segmental mechanism of the arched structure, and then assemble and fix each segmental mechanism on the support frame. Due to the limitation of transportation and overall hoisting factors, it can only be assembled at the factory processing site. If the conventional high-altitude bulk solution is adopted, a large number of high-altitude scaffolds need to be erected on site, high-altitude assembly, welding is difficult, and there is a greater quality and safety. risk. The erection of a large number of scaffolds takes up space and takes up the construction period, which has a great i...

Problems solved by technology

Due to the limitation of transportation and overall hoisting factors, it can only be assembled at the factory processing site. If the conventional high-altitude bulk solution is adopted, a large number of high-altitude scaffolds need to be erected on site, high-altitude assembly, welding is difficult, and there is a greater quality and safety. risk

The erection of a large number of scaffolds takes up space and construction period, which has a great impact on hoisting and interspersed construction of other types of work. The cost is high, and the quality, safety and construction period cannot be effectively guaranteed.
