Abstract
A support system for a rail section which bridges the gap between foundations which are relatively movable auxiliary rails running parallel to the rail across the sleepers which are supported by the foundation, and underpinning supports providing a stiff connection between rail and auxiliary rails. The underpinning supports move in response to relative movement of the foundation so that undesirable rail bending is avoided.
Claims12
A support system for a stock rail extending in a longitudinal direction between foundations which are separated by a variable distance and thus moveable relative to one another while holding said stock rail in position, comprising:
- supporting elements extending across said foundations and arranged to run parallel to both sides of said stock rail;
- and
- said supporting elements including at least one means underpinning said stock rail,
- said underpinning means being moveable in the longitudinal direction of the stock rail and the supporting elements.
For an expansion joint in the area of a bridge, a support system for stock rails laid across a fixed foundation and a movable foundation separated by a variable distance, said stock rail extending in a longitudinal direction being held in position by sleepers which are fixed to foundations, the support system comprising:
- a pair of auxiliary rails extending across the sleepers, each of the auxiliary rails running parallel to a side of the stock rail in said longitudinal direction,
- means underpinning the stock rails extending between the auxiliary rails and perpendicular to the longitudinal direction, said means including braces and clamps for tightening the auxiliary rails to the braces, and
- equalizing means for moving the underpinning means in the longitudinal direction as a function of the distance which separates the foundations.
