Abstract

The invention discloses a large-span steel structure roof hoisting construction method in a complex environment, and belongs to the field of large roof hoisting engineering. According to the method, asegmented steel truss roof is hoisted at three equal division points through two crawler cranes, meanwhile, the structure stability is ensured through the 30-60-degree included angle between a chainand the steel truss roof, collision between the structures can be reduced through a road wheel assembly and a walking track, in addition, the construction cost can be reduced, the construction steps are simplified, and the operation safety is improved. The segmented steel truss roof is stably moved to the tops of required vertical supporting columns, supporting seats and fixing pieces are connected into a whole, then, positioning grooves are separated by adjusting locking units, and accordingly, the road wheel assembly is integrally dismantled. Side slip in the construction process is avoided,accordingly, the safety is improved, meanwhile, the installation accuracy of the steel truss roof is ensured, operation steps are decreased, and the construction cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of large-scale roof hoisting engineering, and in particular relates to a construction method for hoisting a large-span steel structure roof in a complex environment. Background technique

[0002] With the continuous improvement of the level of science and technology, people's requirements for buildings are also getting higher and higher. Thanks to the improvement of the installation level of steel structures, large-span and complex-shaped buildings emerge in endlessly, such as long-span stadiums, waiting (car) airport halls and other architectural shapes that pursue large spaces subvert people's traditional ideas and embody People's dual pursuit of architectural practicality and architectural artistic beauty. However, this also brings great challenges to the constructors. They not only have to create buildings that meet the requirements of the owners, but also overcome the complex environment to ensure the ...
