Document Type and Number:
WIPO Patent Application WO/2013/154190
Kind Code:
A1
Abstract:
[Problem] To easily manufacture a structure composed of a plurality of tetra cubes, and implement excellent compressive strength to use the structure for multiple functions.
[Solution] A tetra cube structure, wherein in a first surface (11) and a second surface (12), quadrangular open edges (3) are formed by crossing a plurality of ridge lines (4) approximately parallel to each other, a quadrangular pyramid-shaped recessed portion (2) is formed by four triangular planes (1X) extending inward from each of the quadrangular open edges (3), a tetra cube (1) is formed by four triangular planes (1X), and adjacent tetra cubes (1) are coupled via boundary lines (1b, 1c) located on both sides of the triangular plane (1X). In the tetra cube structure, a plurality of tetra cubes (1) are arranged in a first direction and a second direction which cross each other, and are composed of a plurality of tetra cube structure rows (10) arranged linearly by coupling the tetra cubes (1) adjacent to each other in the first direction by the boundary lines (1b), and the tetra cube structure rows (10) adjacent to each other are coupled in the second direction by the boundary lines (1c) facing each other.
