<p>Attaching device for a rail by means of elastic fastenings of the type comprising a spring-forming elastic plate tightened by a bolt against a sleeper clip of plated plastic material bearing on the rail support and on the rail base. The spring plate has a triangular or trapezoidal known shape of which the bigger side bears in parallel onto the rail base and covers the plastic sleeper clip which has a substantially identical contour and presents thereto a corresponding concave bearing surface according to the desired deformation of the plate, substantially spherical and centered on the axis of the tightening mean. Application to railway constructions, particularly of the type of long rails, for high speed trains. </p> |
