Formwork for the construction of railway platforms

Formwork for the construction of railway platforms, comprising

• a container in which building material to be shaped and subjected to hardening for the construction of a railway platform can be compacted;
• at least one fixed crossbeam located at the bottom of said container;
• at least one movable crossbeam provided with at least one pair of fastening imprints arranged symmetrically and configured to model said material to form a pair of fastening seats apt to position the rails on said railway platform;
• placed side by side with said fixed crossbeam and defining therewith an impression surface on which said material can be molded for the construction of said railway platform;
• said movable crossbeam being rotatable and/or translatable with respect to said fixed crossbeam, the configuration being such that different rotation and/or translations correspond to different positions in the container of the fastening imprints and different impression surfaces;
• and the formwork characterized in that it comprises moving means associated with said movable crossbeam configured to rotate said movable crossbeam around a center of rotation and/or to translate said movable crossbeam along a radial direction with respect to the center of rotation.
