High-altitude large-span curved roof hydraulic lifting construction method

Abstract

The invention relates to a high-altitude large-span curved roof hydraulic lifting construction method, and belongs to the technical field of structural engineering steel structures. A high-altitude large-span curved roof hydraulic lifting device comprises a curved roof, wherein the curved roof comprises truss upper chords, roof surfaces and truss lower chords; a plurality of roof support columns are arranged on the lower end surfaces of the truss lower chords; a plurality of hydraulic lifting assemblies are arranged between the roof support columns; a plurality of lifting frames arranged at equal intervals are uniformly arranged at the periphery of the curved roof; lifting platform frames are arranged on the lifting frames; hydraulic lifters are arranged at the front ends of the lifting platform frames; steel structure lifting appliances which are in lug type pin connection with the truss upper chords are arranged below the hydraulic lifters; and steel strands which are connected withthe hydraulic lifters in a movable and sleeved manner are arranged between the hydraulic lifters and the steel structure lifting appliances. The construction method has the advantages of large liftingtonnage, short construction period, large operation space, reduction of high-altitude operation volume and reduction of safety risks, and solves the problems of large high-altitude bulk welding volume, large operation risks and unstable construction quality.

Description

technical field [0001] The invention relates to the technical field of structural engineering steel structures, in particular to a hydraulic lifting construction method for high-altitude and large-span curved roofs. Background technique [0002] With the ever-changing development of the steel structure industry, various large-span and large-space architectural designs have emerged, such as: airports, railway stations, convention centers, stadiums, exhibition halls, etc., bringing new possibilities to the installation of steel structures. opportunities and challenges. However, in the construction of super-long-span steel roof steel structures, there are problems that it is impossible to use large-scale equipment to lift or use large-scale equipment to lift uneconomical projects, and due to the large amount of high-altitude bulk welding of complex space truss structures, the cycle is long, and the assembly of space components is difficult. , Large-scale hoisting equipment is ...

Problems solved by technology

However, in the construction of super-long-span steel roof steel structures, there are problems that it is impossible to use large-scale equipment to lift or use large-scale equipment to lift uneconomical projects, and due to the large amount of high-altitude bulk welding of complex space truss structures, the cycle is long, and the assembly of space components is difficult. , Large-scale hoisting equipment is frequently used and the operation risk is high, so the traditional installation technology has been difficult to meet the development needs of today's steel structure industry
