Space Frame structure is a statically indeterminate structure with many bars combination according to certain rules. The large-span space frame is possessed of various installation methods, which created some installation technology of the world’s advanced level. can be roughly divided into the integral hoisting method, integral lifting method, integral jacking method, high slipping method, etc.
- IntegralHoistingMethod When the ground assembly of space frame can be carried out on the spot or outside the field. When choosing the former, the space frame hoisting in the high air need to shift or rotate about 1 ~ 2m, and then fall into place. Because the columns are through the grid of space frame, the beams connected to the columns should be disconnected and be constructed after the lifting of the grid is completed.
- Integral Lifting Method Overall lifting method The overall lifting method refers to the construction method of installing lifting equipment on the structural column to lift the grid frame, or the sliding form of the column while lifting the grid frame. At this time, the grid frame can be used as an operational platform.

- Integral Jacking Method The space frame can use the original structural column as the jacking support, and can also set up a special support or sleeper stack heft. The jack of the jacking method is arranged under the space frame. Guiding measures should be taken in the process of jacking to avoid deviation of the space frame. The jacking method is suitable for point-supported. In the process of jacking, it can only rise vertically without translation or rotation.
- High Slipping Method refers to the installation method in which the space frame unit divided into strips slippage to the design position and splice into a whole on the slide rail set in advance. The strip unit can be assembled on the ground and hoisted to the bracket with a crane. In case of insufficient equipment capacity or other factors, it can also be assembled into a strip unit with small pieces or even pieces on the high altitude assembly platform. The strip elements of the space frame slide from one end to the other end during sliding.
