Elastic double plate for fixing adjacent rails, has rails locked on plate by bolts and clamps, where plate is presented with variable thickness for obtaining proper inertia adapted to variation of elastic deformations from load of rails

摘要

The plate (1) has rails (2) locked on the plate by clamping bolts (5) and elastic clamps (6), where the plate is presented with variable thickness for obtaining a proper inertia adapted to variation of elastic deformations resulting from the load of the rails. The thickness of the plate is increased by extending each rail on a median part of the plate forming an inner upper stop lug from inner edges of the rails. An elastic baseplate (7) is interposed between the plate and a concrete infrastructure, where the baseplate is made of deformable plastic material.
