Abstract:
1. A tenon joint type space lattice structure, comprising a plurality of interchangeable lattice units and at least one combining pillar, wherein: a) each lattice unit comprises a plurality of pre-molded components each extending between respective end portions, a convex tenon and a concave tenon groove, the concave tenon groove having a cross-sectional circumferential arc, the convex tenon and concave tenon groove being respectively disposed on first and second ones of the end portions of the lattice unit, and the tenon and the tenon groove form a tenon-and-groove structure, the tenon groove of one lattice unit being configured to retentively capture the tenon of another lattice unit, a plurality of the lattice units being interconnectable with each other in series to define a continuously extended lattice unit plane layer; and b) the combining pillar interconnects a plurality of stacked plane layers, the combining pillar passing transversely through a hollow portion defined through respective lattice units of the stacked plane layers to form a three-dimensional space lattice structure, wherein each of the lattice units comprises a hollow lattice substantially forming a frame body, the hollow lattice including a plurality of erected and transversally and longitudinally interlaced sheet bodies disposed at each frame edge, the hollow tenon being formed at an end of each lattice along one of the sides of the lattice unit, the tenon groove with an opening facing outward being disposed at an end of each lattice along another side of the lattice unit.
