Method of prefabricating road-supporting girders on a prefabricated beam.

摘要

The method involves arranging model rails (5) on a prefabricated beam (2) i.e. i.e. self-supporting U shaped beam, for positioning a road. A dimension of reservation molds (8) corresponding to a dimension of rail fixation systems is fixed to the model rails at positions of the fixation systems for placing a reservation of the fixation systems on the prefabricated beam. Armatures of road-supporting girders are placed, a casing (12) is realized and a concrete is cast for forming the road-supporting girders. An independent claim is also included for a method positioning rails on a prefabricated beam.
