PREFERRED EMBODIMENT OF THE INVENTION

[0039] In view of the described drawings, it can be observed how in one of the possible embodiments of the invention the modular fastening for track crossings proposed by the invention comprises a lower plate (1) and a shoulder (2) attached by means of adhesive bonding to each end of the lower plate (1), forming a single-block assembly, where each shoulder (2) comprises means for anchoring the fastening on a support surface, the lower plate (1) comprising a central segment (4) running between the shoulders (2) on a face above the face for anchoring to the support surface.

[0040] The fastening comprises two plate assemblies (6, 9), where each plate assembly (6, 9) can be mounted on the lower plate (1) by means of two rail spikes (5) going through the plate assembly (6, 9) and allows the fixing to a rail (B), each plate assembly (6, 9) comprising an intermediate plate (6) the lower face of which comprises a recess (8) for the fitting thereof on the central segment (4) of the lower plate (1), and the upper face of which comprises a circular projection (7) configured for fitting in a circular recess (10) located on a lower face of an upper plate (9) on which a rail (B) can be supported, such that said upper plate (9) can be oriented with respect to said intermediate plate (6).

[0041] Each upper plate (9) comprises two curved elongated holes (11) allowing play of the rail spikes (5) mounting the plate assembly (6, 9) on the lower plate (1).

[0042] The lower plate (1) comprises two parallel guides (3) located in the central segment (4), running from one of the shoulders (2) to the opposite shoulder (2), each guide (3) comprising at least one enlargement (3′) which allows the insertion of a head (5′) of a rail spike (5) for mounting each plate assembly (6, 9).
