The upper and lower honeycombed rib plates are symmetrically arranged, and are spliced by a plurality of basic structures which are in a regular hexagonal shape. Connecting nodes between the adjacent basic structures are of a ring structure. Densities of the upper and lower honeycombed rib plates are adjusted through a density increasing structure.
