1. A modular fastening for track crossings, comprising: a lower plate and a shoulder attached by adhesive bonding to each end of the lower plate thereby forming a single-block assembly, where each shoulder comprises means for anchoring the modular fastening on a support surface, the lower plate comprising a central segment running between the shoulders on a face above a face for anchoring to the support surface, comprising:
two plate assemblies, where each plate assembly can be mounted on the lower plate by means of two rail spikes going through the plate assembly and allows the fixing of a rail, each plate assembly comprising an intermediate plate and an upper plate, wherein;
the lower face of the intermediate plate comprises a recess for the fitting thereof on the central segment of the lower plate, and
the upper face of the intermediate plate comprises a circular projection configured for fitting in a circular recess located on a lower face of the upper plate on which a rail can be supported, such that:
the circular projection and circular recess between the upper plate and the intermediate plate allows the upper plate to rotate with respect to the intermediate plate in different positions; and
wherein each two plate assemblies can be oriented independently so as to allow the adaptation thereof to a variable orientation of two rails supported along different points of a layout, and
further wherein the upper plate comprises at least two curved elongated holes allowing play of the rail spikes mounting the plate assembly on the lower plate and the adjustment by different degrees in both plate assemblies for adapting them in an independent manner to rail orientation changes.
