Hub-cover plate composite aluminum-alloy bilayer grid structure
The invention discloses a hub-cover plate composite aluminum-alloy bilayer grid structure. The hub-cover plate composite aluminum-alloy bilayer grid structure comprises an upper circular cover plate, an insert plate wheel, a lower circular cover plate and a connecting hub node, which are arranged in sequence from top to bottom. The upper circular cover plate, the insert plate wheel, the lower circular cover plate and the connecting hub node are connected by bolts, a plurality of H-shaped section rods are uniformly distributed around the insert plate wheel, a web plate of the H-shaped section rods is inserted and fixed on the insert plate wheel, an upper flange plate of the H-shaped section rods is fixedly connected with the upper circular cover plate, and a lower flange plate of the H-shaped section rods is fixedly connected with the lower circular cover plate. Three hub nodes are uniformly distributed on the same circumference and below the connecting hub node, the connecting hub node is connected with the lower hub nodes through web rods, and the two adjacent lower hub nodes are connected through lower-chord circular section rods. The hub-cover plate composite aluminum-alloy bilayer grid structure can improve in-plane bending resistance rigidity of a disc and cover plate node, anti-buckling deformation of the web plate of the node is improved, the defects of existing hub nodes are overcome, and bearing force of the grid structure is enhanced.
