Embodiment 1
[0039] The crown structure of the main tower was originally designed as a large cone-shaped steel structure embedded in the top section of the main tower. The length*width is 50*50cm; the height of the embedded section of the tower column is 0.8m, and the height of the exposed section is 6m; the total weight is about 22.459t.
[0040]Regarding the construction process of the main tower crown, the traditional method is: firstly manufacture, weld and paint the tower crown in the factory as a whole, and then transport the whole tower to the site for lifting and installation. The following problems were found in the practical application of this method: (1) The original design of the overall production of the tower crown structure, due to the heavy weight of the structure and the large geometric size, it is difficult to flanging welding, moving and hoisting during the overall production, and the manufacturing is inconvenient; Moreover, the structural size of the top of the tower c...
