Embodiment Construction
[0030] figure 1 Shown is a schematic diagram of the general section of the aluminum alloy superstructure hoisting, the hoisting process is as follows:
[0031] Firstly, according to the weight, structural form and center of gravity of the aluminum alloy superstructure total section, determine the number of multiple lifting points, multiple lifting point positions and the overall hoisting method of the aluminum alloy superstructure total section; Two cranes 8, 9 carry out joint hoisting.
[0032] Secondly, make the hoisting hanger 6 of the general section of the aluminum alloy superstructure to control the hoisting deformation. The hoisting hanger 6 here is assembled from profiles such as channel steel, and its structure is as follows: figure 1 It is shown that three rectangles are connected in sequence, because figure 1 The total section shown is divided into three sections, that is, the first section 1 and the second section 2 that are juxtaposed on the bottom floor, and th...
