<p>An underlay plate, or two support plates in conjunction, are screwed or otherwise anchored, and have the rail foot elastic form-locked on or between them, in fixing rails on cross and/or lengthways sleepers or sleeperless support points. The plate (4) and/or plates, for track and junction points, are of initial shape arched inwards and downwards from the edges. They are clamped by sleeper screws (5), or similar, with elastic deformation, flat onto the sleeper top surface (10) or other mounting surface. The apex of the arch pref. coincides with the plate centre line. This permits permanent force-locking fixture, together with reduction of plate size.</p> |
