Each latticed shell structure D includes two cage-shaped trusses A1 arranged at a predetermined angle relative to each other, and a plurality of connecting base frames arranged between the two cage-shaped trusses A1 and connected to each other.

[0054] In the present application, there are a total of 12 cage-shaped trusses A1, which are steel structures and play a supporting role in the entire cage-shaped latticed shell, and also play a role in fixing the connecting base frames. Each latticed shell structure D includes two cage-shaped trusses A1, and the predetermined angle between the two cage-shaped trusses A1 is 80°; each latticed shell structure D includes a plurality of connecting base frames, which are connected in sequence along the radial direction of the building to form a cage-shaped latticed structure.

[0055] When the cage-shaped reticulated shell is installed, the four reticulated shell structures D can be installed in advance in a production factory, then transported to the installation site of the building, hoisted and connected to form the entire cage-shaped reticulated shell, which is beneficial to improve the installation efficiency and save the installation cost. Of course, the 12 cage-shaped trusses A1 can also be arranged at the installation site of the building, and then the connecting base frames are arranged to gradually form the entire cage-shaped reticulated shell.
