Each fastener node of the floating rail fastener system consists of a cast iron base, two cast iron side panel brackets, two cast iron wedge-shaped block fixing pieces, two elastic wedge-shaped steel rail supports with rubber elastic blocks, a safety supporting rubber pad under the rail and two spring clamping pieces. Normally, the safety support rubber pad is not contacted with the steel rail, so that excessive deformation caused by load can be effectively limited. The floating rail fastener has the advantages of simple structure, easy installation, convenient maintenance, safety, stability and reliability, and is especially used for places with high requirements on vibration reduction and noise reduction, such as subways, railway bridge lines in urban areas and the like. The floating rail fastener system can be used for a ballasted track and a ballastless track, and is widely applied to railway tracks in various countries of the world.

The positioning wedge block and the supporting block are respectively provided with insections for mutual occlusion; one side of the positioning wedge block provided with the insections is clung to the supporting block, and one side of the positioning wedge block away from the insections is clung to the supporting plate.
CN201120439915.4 proposes a suspension rail vibration damping fastener installed in a chute, the position on the fastener bottom plate combined with the lateral bracket has a structure for limiting the lateral bracket, the limiting structure should have at least one limiting surface i for limiting the lateral bracket moving along the laying direction of the rail, and at least one limiting surface ii for limiting the lateral bracket moving vertically; and a space for horizontally moving the lateral support perpendicular to the rail laying direction is formed between the limiting surface I and the limiting surface II. The utility model can effectively control the movement of the lateral bracket in the up-down direction and the rail laying direction, and also can effectively control the torsion of the lateral bracket caused by the torsion of the rail, thereby effectively enhancing the stability of the lateral bracket structure and ensuring the safety of the vehicle. One side of the distance adjusting stop block is abutted against the lateral bracket, and the other side corresponding to the side abutted against the distance adjusting stop block of the lateral bracket is abutted against a side wall surface of the groove formed in the fastener bottom plate; the contact surfaces of the distance-adjusting stop block and the lateral support are identical inclined surfaces, and the identical inclined surfaces are in convex-concave buckling or plane combination; the distance adjusting stop block is matched with one side of the wall surface of the groove of the fastener bottom plate in an inclined plane manner; the contact surfaces of the distance adjusting stop block and the other side wall surface of the groove of the fastener bottom plate are mutually matched straight surfaces, and convex-concave buckling or plane combination is adopted between the matched straight surfaces.
