Abstract
The present invention relates to a modular fastening for track crossings comprising a lower plate (1), an upper plate (2) and an outer shoulder (3) at each end of the plates, attached by means of adhesive bonding, comprising means for anchoring the fastening on a surface (A). The upper plate (2) comprises a smooth central segment (2′) located between two grooved areas (2″) in correspondence with the ends of the upper plate (2). The present invention also comprises two inner shoulders (4) with lower grooves (4′) which can engage and fit into the grooved areas (2″) of the upper plate (2), where said inner shoulders (4) comprise means for housing and securing an elastic fastening clip (B) for fastening a railway rail (C).

Modular fastening for track crossings, comprising:
- a lower plate (1) on which there is placed
- an upper plate (2), and
- an outer shoulder (3), located at each end of the plates (1, 2), comprising means for anchoring the fastening on a support surface (A), where the plates (1, 2) and the outer shoulders (3) are attached by means of adhesive bonding, forming a single-block assembly,
- characterized in that
- the upper plate (2) comprises a smooth central segment (2′) located between two grooved areas (2″) located in correspondence with the ends of the upper plate (2),
- the fastening comprising two inner shoulders (4) comprising lower grooves (4′) which can engage and fit into a plurality of positions on the grooved areas (2″) of the upper plate (2), where said inner shoulders (4) comprise means for housing and securing an elastic fastening clip (B) for fastening a railway rail (C).
Modular fastening according to any of the preceding claims, wherein the upper plate (2) comprises a longitudinal channel (2′″) running from one grooved area (2″) to the opposite grooved area (2″) and going through the smooth central segment (2′), where the inner shoulders (4) in correspondence with the lower grooves (4′) comprise a guide bridge-like channel (4″).
Modular fastening according to any of the preceding claims, wherein the smooth central segment (2′) of the upper plate (2) comprises on the upper portion thereof a base plate (6) for the rail (C), where said base plate (6) comprises two larger sides and two smaller sides, the length of each of the larger sides coinciding with the length of the smooth central segment (2′) of the upper plate (2).
Modular fastening according to any of the preceding claims, wherein the means for housing the elastic clip (B) comprise a longitudinal cavity (7) made on one side of the inner shoulders (4) for supporting the curved outer areas (B′) of the elastic clip (B), a central raised area (8) in said longitudinal cavity (7) separating the curved outer areas (B′) and acting as a lateral stop for said outer areas, and a central through hole (9) for the screw for fastening the elastic clip (B) to the rail (C) and the actual inner shoulder (4) to the upper plate (2).
