3. 1. Aerial bulk installation method High-altitude bulk installation refers to the method of total assembling of small assembled units or loose parts directly in the design position, applicable to the installation of space structure such as space frame and reticulated shell.

4. 2 . Split strip or block installation method This method is based on the characteristics of the composition of the space frame and the ability of lifting equipment, the first space frame on the ground into strips or blocks of units, respectively, lifted by the crane to the high-altitude design position in place, and then assembled into a whole installation method. The principle of dividing the size of the strip or block is to adapt the weight of each unit with the existing lifting equipment on site. Most of the welding, assembling workload on the ground, is conducive to improving the quality of the project.

5. 3 . slip construction method Refers to the slitting of the net frame unit in the pre-set sliding rail on a single slip to the design position spliced into a whole installation method. This strip unit can be put together on the ground with a crane to the stent, such as insufficient equipment capacity or other factors, can also be used for small spelling unit or even loose parts in the high altitude assembly platform put together into a strip unit. Aerial stent is generally located at one end of the building, slip when the net frame of the strip unit from one end to the other end.

6. 4 . Overall lifting method After the space frame is assembled on the ground, single or multiple rods are used, and one or more cranes are used to lift the construction method.

7. 5 . Overall jacking method The space frame is assembled on the ground, using the building load-bearing columns as the support structure for jacking up, and the jacks are used to jack up the net frame to the design elevation.

8. 6 . Overall lifting method The use of lifting devices will be assembled on the ground or floor structure gradually lifted to the established position of the construction method. Using this construction method, do not need a large crane, equipment investment is also less, construction safety and reliability, has a better synthesis and benefits.
