Abstract
A rail pad that is formed from elastomeric material has an upper face adapted to underlie a lower face of a rail. The lower face is adapted to overlie a concrete rail foundation member. The elastomeric rail pad generally has a rectangular plan configuration. The elastomeric pad includes a reinforcement member, which is generally parallel to its mean plane and which extends at least between dispositions associated with generally opposing comers of the generally rectangular pad. The reinforcing member has a tensile strength sufficient to resist forces from traffic passing across the rail, which tend to stretch the pad in the mean plane.
Claims24
An elastomeric rail pad of substantially rectangular plan configuration, the pad having:
- an upper face adapted to underlie the lower face of a rail;
- a lower face adapted to overlie a concrete rail foundation member;
- a reinforcement means, other than fabric reinforcement, the reinforcement means being substantially parallel to a mean plane of the pad, the reinforcement means extending at least between substantially diagonally opposing corners of the pad;
- said reinforcement means having a tensile strength such as to resist, in use of the pad, forces from traffic passing across the rail disposed thereabove otherwise tending to stretch the pad in the mean plane thereof;
- wherein the reinforcement means is in the form of a cruciform extending between corners of the substantially rectangular pad.
An elastomeric rail pad of substantially rectangular plan configuration, the pad comprising:
- an upper face adapted to underlie the lower face of a rail;
- a lower face adapted to overlie a concrete rail foundation member;
- a reinforcement means, other than fabric reinforcement, the reinforcement means being substantially parallel to a mean plane of the pad, the reinforcement means extending at least between substantially diagonally opposing comers of the pad;
- said reinforcement means having a tensile strength such as to resist, in use of the pad, forces from traffic passing across the rail disposed thereabove otherwise tending to stretch the pad in the mean plane thereof;
- wherein the reinforcement means is contiguous with the lower face of the pad;
- wherein the reinforcement means comprises a reinforcing member attached to the lower face of the pad;
- and
- wherein the reinforcing member has a plurality of apertures disposed over its area, which apertures in use serve to grip elastomeric material of the rail pad.
An elastomeric rail pad of substantially rectangular plan configuration, the pad comprising:
- an upper face adapted to underlie a lower face of a rail;
- a lower face adapted to overly a concrete rail foundation member;
- a reinforcement means in the form of a cruciform extending between corners of the pad;
- the reinforcement means being substantially parallel to a mean plane of the generally rectangular pad and extending at least between substantially opposing corners of the pad, said reinforcement means having a tensile strength such as to resist, in use of the pad, forces from traffic passing across the rail disposed thereabove otherwise tending to stretch the pad in the mean plane thereof.
A method of protecting a foundation member for a railway rail from impulsive and other loads from rail traffic passing over the rail, which method comprises:
- forming an elastomeric rail pad to have a substantially rectangular plan configuration;
- providing to the elastomeric rail pad with:
- an upper face adapted to underlie the lower face of a rail;
- a lower face adapted to overlie a concrete rail foundation member;
- a reinforcement means, other than fabric reinforcement, the reinforcement means being substantially parallel to a mean plane of the pad, the reinforcement means extending at least between dispositions associated with substantially diagonally opposing corners of the pad, said reinforcement means having a tensile strength such as to resist, in use of the pad, forces from traffic passing across the rail disposed thereabove otherwise tending to stretch the pad in the mean plane thereof;
- wherein the reinforcement means is in the form of a cruciform extending between corners of the substantially rectangular pad;
- and
- positioning the elastomeric rail pad between the foundation member and the railway rail.
