摘要

System for building three dimensional structures from two unfolding layers, made from frames of multi-angled rhomboids and rods.It is made by joining together elemental modules (1, 9, 12, 15) based on the rhomboid and the simple rod, arranged in two layers which are separated from each other by oblique bars (3), allowing the use of two clearly differentiated architectural elements: ceiling below and covering above the roof respectively. When assimilated with a sheet, it allows the distortions to be controllable and the unit to have a high rigidity in the face of distortions depending on the pre-set distance between the two layers.The elemental module (1) is formed by a rhomboid of bars (2), each one of which carries associated in a vertical plane two other oblique or diagonal bars (3). The four points of cut of these diagonals (3), or lower nodes (4) are joined alternately with a simple rod of bars (5) in a plane below the rhomboid. Th elemental modules are joined to each other by the vertices (6) of the upper rhomboid and the lower points or nodes (4) with simple rods (7).IMAGE
