Abstract
Beams extend transversely outwards from at least one side of each span beyond the corresponding side flange and shelf. Each beam is of a length in the transverse direction and of strength that are predetermined to be sufficient for enabling additional structures, e.g. slabs, to be installed subsequently on said beams, which additional structures preferably extend said soleplates outwards, in particular to form a station.
Claims8
A viaduct for a railway line or the like, the viaduct comprising successive spans resting on supports such as piers, each span having a substantially U-shaped cross-section comprising a load-carrying slab forming the web of the U-shape and connected on either side to an upwardly-extending side flange, the top portion of each flange being surmounted by a substantially horizontal shelf-forming soleplate extending transversely at least towards the opposite flange, the viaduct including, for at least some of its spans, beams extending transversely outwards from at least one side of said spans beyond the corresponding side flange and shelf, each beam being of length in the transverse direction and of strength that are predetermined to be sufficient to enable additional structures to be built subsequently on said beams, e.g. slabs which preferably extend said soleplates outwards.
A viaduct for a railway line or the like, substantially as herein described with reference to and as illustrated in the accompanying drawings.
