PCT No. PCT/EP96/04989 Sec. 371 Date May 12, 1998 Sec. 102(e) Date May 12, 1998 PCT Filed Nov. 17, 1996 PCT Pub. No. WO97/19231 PCT Pub. Date May 29, 1997A 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 of reinforced concrete. These elements are able to define the side walls and the deck of the work with adjacent longitudinal sections of the structure which rest on a foundation at the base of the work. Each section of the structure includes a pair of side elements which rest on the foundation via a static hinge and are intended to be disposed symmetrically with respect to the axle of the structure so as to assume a substantially L-shaped configuration. A substantially rectilinear prefabricated element is interposed centrally between two side elements and is anchored thereto so as to define a central portion of the deck of the work.
