<p>A prefabricated structure for the construction of open air structures, particularly motorway flyovers, underpasses, bridges, tunnels, underground carparks and the like, includes a plurality of prefabricated elements (5, 7) of reinforced concrete. These elements (5, 7) are able to define the side walls and the deck (9) of the work with adjacent longitudinal sections of the structure (1) which rest on a foundation (3) at the base of the work. Each section of the structure (1) includes a pair of side elements (5) which rest on the foundation (3) via a static hinge (11) and are intended to be disposed symmetrically with respect to the axis of the structure so as to assume a substantially L-shape configuration. A substantially rectilinear prefabricated element (7) is interposed centrally between two side elements (5) and is anchored thereto so as to define a central portion of the deck (9) of the work.</p> |
