Problems solved by technology

However, for the large-span and ultra-high grid structure with a curved grid shell on the roof and an inclined flat grid grid on the facade, the above construction schemes are deficient in terms of construction cost, construction quality and construction safety. Perfect
[0006] At present, the design and construction of ultra-high arched grid structures are still in the stage of exploration and research in my country and the world, and there are no cases of completion acceptance.

Embodiment 1

[0066] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the installation method of super-high arched grid structure computer-controlled external expansion cumulative lifting is carried out according to the following steps:

[0067] (1) Calculation and analysis before spinning:

[0068] Use calculation software to calculate and analyze the whole construction process to ensure that the structure itself and the lifting system can meet the relevant mechanical and structural requirements during the construction process, and ensure that the construction process is safe and controllable;

[0069] (4) Calculation control during construction:

[0070] The synchronous control requirements of hydraulic lifting construction are high, and the computer synchronous control system is adopted during the construction process, and the monitoring during the lifting process is s...

Abstract

The invention relates to a method of erection, in particular to a computer-controlled expansion accumulative lifting method for erecting a super-high arch grid structure, and belongs to the field of steel structures. The method includes the steps of pre-construction computational analysis, under-construction computational control, preparation before unit grid lifting, selection of a hoisting mode, selection of hoisting site conditions, supporting with temporary members of unit grids, staged hoisting, and installation of accessories. The method has the advantages that the structure is compact, the assembly mode is industrialized, the erection period is short, and operational flexibility is high.

Description

technical field [0001] The invention relates to an installation method, in particular to an installation method for super-high arched grid structure computer-controlled external expansion cumulative lifting, which belongs to the field of steel structures. Background technique [0002] With the continuous emergence of large-span and large-area grid structures, the construction height and span of large-area grid structures continue to increase. Traditional construction methods not only increase construction costs and lengthen construction periods, but also reduce construction safety. Therefore, seeking a safe, fast and low-cost construction method is one of the key points of the current large-area and long-span grid construction research. [0003] The ultra-high arched grid structure is a grid structure with welded ball nodes as the main form, which is suitable for columnar or arched structures with large span, light weight, and reasonable stress. This type of structure is wi...
