In this embodiment, the node connection plate 1 is a T-type node connection plate 1. The T-type is used when the node is only under compression or tension and compression exist at the same time.

[0026] Preferably, multiple node connection plates 1 are evenly arranged in the circumferential direction of the connecting rod 3. The number of node connection plates 1 can be determined according to the angle of the web member and the collision conditions, and can be two, three, four or more as required. In this embodiment, four node connection plates 1 are provided as an example for specific description. The size of the node connection plate 1 and the size and length of the weld are determined according to the internal force conditions.

[0027] Specifically, the node connection plate 1 is connected to the annular rib plate 2 by welding, and the two ends of the node connection plate 1 are respectively welded to two connecting rods 3, and each connecting rod 3 is correspondingly provided with at least two annular rib plates 2 (the figure takes the example of each connecting rod 3 correspondingly providing two annular rib plates 2 for specific description).

[0028] Furthermore, at least two annular ribs 2 corresponding to the connecting rod 3 are connected via a reinforcing rib. The reinforcing rib can effectively prevent the annular rib 2 from lateral buckling and improve the overall stability of the connection node.
