The grid structure in the high-altitude sliding method is an overhead operation, which has no influence on the internal construction of the building. The grid structure can be operated in parallel with other constructions below, which can speed up the construction progress and shorten the construction period, without the need of large equipment and traction equipment.The upper-air sliding method refers to the single slide (or one by one) on the sliding track set up in advance of the tile press unit to describe the direction of the assembly of the device method is particularly suitable for the selection of the grid frame and carried out across the project and the demand for three-dimensional cross construction.The key point of construction is the control of synchronous slip of slip unit

The hoisting method refers to the construction method that the net frame is in place with lifting equipment after it is assembled on the ground.The welding and splicing of the whole net frame are carried out on the ground, simply ensuring the quality of construction.Because the entire grid of the emplacement depends on lifting equipment to complete, so the ability of lifting equipment and lifting and moving control is particularly important.The whole hoisting method is applicable to all types of net rack under the condition of place and hoisting equipment.The key point of construction is the control of the simultaneous rise of the grid and the control of the displacement of the grid in the air.
