Abstract: A modularized framework structure of a three-dimensional truss structure is obtained as a result of making unit modules and interconnecting the unit modules. Each of the unit modules is made of frames, having elongated joining surfaces and connected mutually at end portions, to conform to a regular tetrahedron or octahedron. The elongated joining surfaces are obtained as a result of planarly truncating surfaces of edges of the frames corresponding to ridgelines of the regular tetrahedron or octahedron such that the elongated joining surfaces can be joined mutually, and the elongated joining surfaces are oriented orthogonally to perpendiculars drawn from the center to the corner centers of the elongated joining surfaces to form a Tetra- or Octa-module. The unit modules as the Tetra- or Octa-module are interconnected by joining mutually the elongated joining surfaces of the frames thereby to form the three-dimensional truss structure.
