Abstract:
1. A 3-D structural module (3-D module) for assembly in a load-carrying modular structure, said 3-D module being designed as a body constituting a complete or partially cut-out parallelepiped with rectangular sides and comprising at least one reinforcing diagonal beam (RDB) disposed along a diagonal (R-diagonal) that connects vertices (R-comers) of said parallelepiped, said body having flat faces constituting parts of said rectangular sides, said RDB including means for rigid assembly to a RDB of another 3-D module, such that a plurality of 3-D modules can adjoin each other along their flat faces, and their RDBs can be assembled to each other at said flat faces so as to form a 3-D rigid multi-tetrahedron lattice in said modular structure, whereby said modular structure behaves under load as a multi-tetrahedron structure.
