<p>This invention relates to space structures, in particular grids, which are used as roof or floor load bearing structures in industrial buildings and public houses and it relies on that the system is made from the set of planar, prefabricated elements in the form of triangular (1) and square frame units (2) and also square units with additional diagonal member, which are interconnected at the corners by means of dismantable or permanent connections and, those units, assembled together, compose a double layer grid with one layer having an orthogonal configuration of chords in relation to support lines or they compose a double layer grid with doubled depth and the same either diagonal or orthogonal configuration of both layers, as well as they compose a triple layer grid using square units with diagonal member.</p> |
