[0065] In summary, a more specific embodiment of this utility model is as follows:

[0066] Before use, the support and positioning components of the irregularly shaped cantilevered steel beam structure described above need to be installed as a backup.

[0067] Example 1

[0068] like Figure 2 and Figure 3 As shown, a support and positioning component for an irregularly shaped cantilevered steel beam structure includes multiple steel cantilever brackets 1, which are respectively connected to the lower outer side of the building body 8; lifting lugs 2, which are respectively connected to each steel cantilever bracket 1 and to the building body 8 located above each steel cantilever bracket 1; reinforcing components 3, which are respectively connected between two vertically corresponding lifting lugs 2 to improve the installation strength of the steel cantilever bracket 1; two I-beams 4, which are spaced apart above each steel cantilever bracket 1; and several fixing components 5, which are used to securely connect the two I-beams 4 to the top of the multiple steel cantilever brackets 1.

[0069] In this utility model, the lifting lug 2 is generally in the shape of a c-shape, and the two sides of the lifting lug 2 are symmetrically provided with lifting lug connection holes.

[0070] Furthermore, multiple steel cantilever brackets 1 are connected to the building body 8 via pre-embedded bolts 11.

[0100] Multiple support component units are connected to each other by threads to form a support component. The mounting sleeve 68 at the bottom of the support component is fixedly connected to the inner ring of the bearing 62 by a connecting threaded post 612.

The inner ring of each bearing 62 is fixedly connected with a connecting threaded column 612. At this time, the mounting sleeve 68 on the support component unit can be threaded onto the connecting threaded column 612, and then stacked on the support component unit in sequence to increase the height of the support component. The connecting threaded column 612 can rotate inside the bearing 62, thereby allowing for appropriate height adjustment for ease of use.
