ABSTRACT:
A tenon joint type space lattice structure having a plurality of lattice units and combining pillar is provided. The lattice unit includes a convex tenon and a concave tenon groove disposed at ends of the lattice to form a tenon-and-groove structure. The tenon of one lattice unit may be embedded within an adjacent tenon groove for connecting the lattice units in series to form a continuously extended layer of lattice units. The continuous structure of lattice units forms a plane layer of a space lattice structure. The combining pillar may be passed perpendicularly through a hollow portion of a lattice unit for connecting plane layers of lattice units stacked one over the other to form a three-dimensional space lattice structure. A heavy filling material may fill the hollow portion of the structure to form a gravity structure.
