Embodiment 1

[0042] Example 1: If figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a method of lifting and installing a high-curved grid is carried out in the following steps:

[0043] (1) Upgrading preparation stage:

[0044] 1) The grid frame of the facade support part of the ultra-high curved grid frame is first installed in place, and temporarily fixed by means of lattice support frame and wind rope. The distance between the support frame is 15-30m, and the wind rope is used to pull Set at 2 / 3 of the height of the supporting part of the facade, the angle between the wind rope and the ground is controlled within the range of 30-45 degrees; the height of the supporting part of the facade is within the range of 60m or less;

[0045] The height of the ultra-high curved grid structure is 80m;

[0046] 2) Assemble the 60m or more arched grid of the ultra-high curved grid on the assembly tire frame directly below its projection to reduce the assembled height of the cu...

Embodiment 2

[0060] Embodiment 2: A method for lifting and installing a high-curved network frame, which is carried out according to the following steps:

[0061] (1) Upgrading preparation stage:

[0062] 1) The grid frame of the facade support part of the ultra-high curved grid frame is first installed in place, and temporarily fixed by means of lattice support frame and wind rope. The distance between the support frame is 15-30m, and the wind rope is used to pull Set at 2 / 3 of the height of the supporting part of the facade, the angle between the wind rope and the ground is controlled within the range of 30-45 degrees; the height of the supporting part of the facade is within the range of 70m or less;

[0063] The height of the ultra-high curved grid structure is 100m;

[0064] 2) Assemble the 70m or more arched grid of the ultra-high curved grid on the assembly tire frame directly below its projection to reduce the assembly height of the curved grid; the height of the arched grid is 60...

Embodiment 3

[0078] Embodiment 3: A method for lifting and installing a high-curved grid structure, which is carried out according to the following steps:

[0079] (1) Upgrading preparation stage:

[0080] 1) The grid frame of the facade supporting part of the ultra-high curved grid frame is installed in place first, and the measures of lattice support frame and wind rope are adopted for temporary fixation. The distance between the support frames is 30m, and the wind rope is pulled at At 2 / 3 of the height of the supporting part of the facade, the angle between the wind rope and the ground is controlled within the range of 45 degrees; the height of the supporting part of the facade is within the range of 80m or less;

[0081] The height of the ultra-high curved grid structure is 116m;

[0082] 2) Assemble the 80m or more part of the arched grid of the ultra-high curved grid on the assembled tire frame directly below its projection to reduce the assembled height of the curved grid; the heig...

Abstract

The invention relates to high curved-surface net racks, particularly to a lifting and installation method of high curved-surface net racks, which can be applied in building steel structures. The lifting and installation method proceeds according to the processes of a lifting preparation stage and a lifting stage. According to the lifting and installation method of high curved-surface net racks, the structure is compact, the requirements for mechanical equipment is low, the construction efficiency is improved, the construction cost is reduced, and the construction safety is improved.

Description

technical field [0001] The invention relates to a high-curved net frame, in particular to a method for lifting and installing a high-curved net frame, which is applied to building steel structures. Background technique [0002] With the development of the construction industry, the application of steel structures in building structures is becoming more and more extensive, especially the application of space grid structures in large-span, large-area, and ultra-high structures is gradually increasing. The traditional installation method of ultra-high curved surface grid has disadvantages such as high construction cost, high construction safety risk, long construction period, and difficult construction quality assurance. Therefore, one of the key points in the current research on the construction of ultra-high curved grids is to seek safe, fast and low-cost construction methods. [0003] The ultra-high surface grid structure is a grid structure formed by bolted ball or welded ...
