Abstract (en)
[origin: US4660243A] A method is described for the sectional erection of a superstructure of prestressed concrete for a bridge with a launching girder carrying the formwork for the superstructure and being movable from one concreting section to the other. The process is characterized by a movement of the launching girder to the next concreting section while the previously concreted and prestressed superstructure is supported via bearings by the launching girder, which in turn is supported by the bridge supports via further bearings.
