Fold-Out Prefabricated Structure and Method for the Assembly Thereof

A prefabricated construction structure having any number of porticos that allows obtaining a final structure of various shapes and dimensions, which is delivered folded-up, comprising a base (1) built in one or several pieces, susceptible to being fixed to the surface and prepared for being cut or separated into as many portions as there are pillars, said pillars (8, 9, 10, 11, 12, 13) having any dimensions, shape, section and inclination, attached to the base, which can be different from one another, an upper structure (27) made up of elements of any length, shape and section, which can be different from one another, with finishes that allow fitting with others at the chosen angle, attached to one another and to the pillars by articulations or other moving elements (25, 26), which are delivered folded-up and expanded to their final position throughout the fold-out process, stiffening elements (29) providing strength to the conglomerate and allowing groups of structural elements to be opened and moved as a result of auxiliary structures (14) assuring the relative arrangement between sets of pillars during the required fold-out movements.
