Synchronous jacking construction method for large-span steel roof truss by multiple hydraulic equipment

Abstract

The invention discloses a synchronous jacking construction method for a large-span steel roof truss by multiple hydraulic equipment, and relates to the technical field of building construction. The synchronous jacking construction method comprises the following steps of arrangement and projection of jacking points of a jacking area, truss assembly, welding, truss lifting, preparation work before hydraulic jacking, steel roof truss overall synchronous jacking, construction quality inspection and jacking equipment unloading; and through the synchronous jacking construction method, the large-spansteel roof truss is simultaneously jacked up by the multiple hydraulic equipment, and the effects of shortening the construction period of the entire long-span steel roof truss, improving construction safety and construction quality and reducing construction cost are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, it relates to a construction method for synchronously jacking up a large-span steel roof truss by multiple hydraulic equipment. Background technique [0002] In the architectural design concept at the present stage, with the continuous updating of the architectural design concept, the aesthetic requirements of the overall shape of the building and the diversification of functions, the large-span spatial structure is more and more favored by architectural designers. At present, the large-span spatial structure is mainly used It is applied to the roof structure of large public buildings such as large passenger transport buildings, large conference buildings, stadiums, and exhibition halls. [0003] The large-span space steel structure has been widely used due to its unique advantages. Among them, the high-altitude bulk method and the overall hoisting method are rela...

Problems solved by technology

[0003] The large-span space steel structure has been widely used due to its unique advantages. Among them, the high-altitude bulk method and the overall hoisting method are relatively recognized and widely used; the high-altitude bulk method requires professionals to carry out the construction and installation of the truss at high altitudes, and the safety is unreasonable. To ensure a better guarantee, some projects still need to set up a full house of scaffolding as an operating platform, the cost of renting scaffolding is high, and the safety of construction personnel cannot be well guaranteed; the overall hoisting method not only requires very professional large-scale hoisting equipment, but also requires The hoisting conditions on the site are high, and a work area for hoisting large-scale mechanical equipment is required; therefore, according to the construction technology of how to raise the steel roof truss to the construction level in the traditional long-span steel roof truss construction technology, the construction period of the entire long-span steel roof truss , construction safety and construction cost are particularly important
