- railway networks in the form of a compact concrete roadway are made with a plurality of road segments arranged one after the other.
- the road segments are constructed on site by pre-assembling a formwork system that has to withstand the pressure of the fresh concrete, ensure the completion of the clean segment, and provide straight faces between adjacent road segments.
- the formwork systems are formed by panels of stable materials, covering the total width of the individual road segments, both the assembly and the removal of the formwork after the concreting being expensive to free the roadway for rail tracks . Also, the installation and removal of the formwork is frequently associated with difficulties and partial destruction of the formwork material, particularly when the rails are already mounted on the road segments.
- the present invention seeks to solve one or more of the drawbacks set forth above by means of a rail formwork segment for rail tracks as defined in the claims.

- the formwork segment penetrates the hearth of the spilled material or vice versa to increase the adhesion between them.
- the formwork segment is adapted to withstand the pressure of the fresh poured material within the hollow space of the formwork segment and, subsequently, of the cured material hardened by curing or setting.

- the formwork segment includes a plurality of gaps or recesses suitable for receiving a plurality of rail support points for mounting and fixing two rails that run parallel to each other. The points of support are projected beyond the surface of the hearth of the material poured into a default height
- the formwork segment is also configured to embed into the poured material the plurality of rail support points for mounting and fixing two rails that run parallel to each other. Therefore, the support points of the rails must be laid individually or in the manner of sleepers within the formwork segment before emptying the material poured into the hollow space of the formwork segment.
- the formwork segment is configured to supply two rows of continuous gaps parallel to the longitudinal axis of the formwork segment for embedding and fixing two rails that run parallel to each other within the hearth of the poured material.
- the rails before being embedded in the formwork segment are jacketed with elastic material that wraps the rails and provides elastic properties that dampen vibrations and noise generated by the circulation of rail vehicles.
- the elastic material is installed inside the continuous gap between the rail and the floor of spilled material.
- the formwork segment is made from a composite material of the reinforced polymer fiber material type, thermoplastic materials, or the like.
- Figure 1 shows in a perspective view an unfilled formwork segment of poured material; the formwork segment has a substantially rectangular cross section,
- Figure 2 shows in a perspective view the formwork segment with two rows of empty gaps to receive rail support points for mounting and fixing two rails that run parallel to each other; the lower outer face of the formwork segment is mounted in physical contact with a blanket of elastic material,
- Figure 3 shows in a perspective view the formwork segment with two rows of empty holes receiving rail support points to which two rail tracks are mounted and fixed; the formwork segment being mounted in physical contact with the elastic material blanket,
- Figure 4 shows in a perspective view the formwork segment with two rows of empty gaps receiving rail support points to which two rail rails are mounted and fixed; the formwork segment being mounted in physical contact with the blanket of elastic material, and where the support points project beyond the surface of the floor of the material poured at a predetermined height, and
- Figure 5 shows a perspective view of a continuous railroad track lane comprising a plurality of juxtaposed formwork segments abutting formwork segments with other formwork segments.
- the road segment 41 comprises a formwork segment 11 in which a poured material has been emptied to form a solidary and monolithic assembly ; where the formwork segment 11 is non-removable from the road segment 41.
- the formwork segment 11 has a substantially rectangular cross section.
