Formwork for the construction of railway platforms
Formwork (1) for the construction of railway platforms, comprising: a container (2) 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 (3) located at the bottom of the container (2); at least one movable crossbeam (4) provided with at least one pair of fastening imprints (5) arranged symmetrically and configured to model the material to form a pair of fastening seats apt to position the rails on the railway platform; placed side by side with the fixed crossbeam (3) and defining therewith an impression surface on which said material can be molded for the construction of said railway platform; said movable crossbeam (4) being rotatable and/or translatable with respect to said fixed crossbeam (3), the configuration being such that different rotations and/or translations correspond to different positions in the container (2) of the fastening imprints (5) and different impression surfaces.
