Abstract (en)
[origin: US6325301B1] In a device for supporting a rail fastened to a sole-plate resting on an anti-vibration pad, the sole-plate is urged towards the supporting structure by at least one adjustable prestressing resilient device acting on the sole-plate so as to apply a defined prestressing force to the anti-vibration pad. Each prestressing resilient device includes a threaded bolt, an adjusting nut and a vertically acting spring assembly which comprises a first spring having a first stiffness, a second spring arranged round the first spring and having a second stiffness higher than said first stiffness, and a device for retaining said first and second springs in such a way that each of said springs is able to act independently from the other one.
