Abstract

The invention relates to a noise reducing track covering comprising cover elements (6, 7) arranged on the track. The cover elements (6, 7) have a shee t- like base (8) with a layer (10) on the upper side (9) thereof for the rootin g of plants (11). The cover elements (6, 7) are provided with support lugs (15 ) on the edges thereof facing the rails, which engage in lateral recesses in t he rails with intermediate elastomer profiles (16). The cover element (6) place d between rails are mounted exclusively by means of said support lugs (15) on the rail (2, 2') and bridge the space (17) between the rails in a self- supporting manner. Cover elements (7) connected to the outside of the rail a re supported on one side with the supporting lugs (15) thereof on the rails and on the other side on foundations (18) and bridge the space between the rails and the foundations in a self-supporting manner.

Claims

1. A noise-reducing track cover comprising cover elements (6, 7) arranged on the track, these cover elements (6, 7) having a slab-like base (8) and, on their upper side (9), a layer (10) provided for plants (11) to take root therein, characterised in that cover elements (6) arranged between the rails (2, 2') of the track (1) are provided, which cover elements have support-ing noses (15; 30) at their rims (14) that face the rails (2,

2'), which supporting noses engage in the lateral recesses of the rails (2, 2') with elastomer sections (16) interposed, and rest on the rails merely by means of these supporting noses and self-supportingly bridge the space (17) between the rails from rail (2) to rail (2').
2. A track cover according to claim 1, characterised in that cover elements (7) arranged to externally adjoin the rails (2, 2') are provided, which cover elements (7) have supporting noses (15) on their rim (14) that faces the respective rail (2, 2'), said supporting noses engaging in the lateral recesses of the respective rails (2, 2') with elastomer sections (16) inter-posed, said cover elements (7) being supported on the respective rail merely by these supporting noses and, on their side facing away from this rail, are supported on a pedestal (18) provided adjacent the track and self-supportingly bridge the space between the respective rail and the pedestal.

3. A track cover according to claim 1 or 2, characterised in that the layer (10) provided for plants (11) to take root therein is covered by a non-woven fabric (20).

4. A track cover according to claim 1 or 2, characterised in that the slab-like base (8) of the cover elements (6, 7) has a sufficient dimensional stability at least for walking thereon and for moving thereon with light equipment.

5. A track cover according to any one of claims 1 to 4, char-acterised in that the slab-like base (8) of the cover elements (6, 7) has the shape of a U-section (27) extending transversely to the rail-longitudinal direction, which U-section is formed of a substantially plane bottom plate (28) and of flange ribs (29) projecting upwards from the bottom plate (28) and provided at those rims of the bottom plate which extend transversely to the rail longitudinal direction, the rail-side supporting of the cover elements being effected by supporting noses (30) which are formed by the ends of the flange ribs (29) that face the rails.

6. A track cover according to any one of claims 1 to 4, char-acterised in that the cover elements (6) arranged between the rails (2, 2') of the track so as to extend from rail to rail are designed in the form of partial cover elements (31,31') forming element pairs, the partial cover elements of each pair being as-sembled in hinge-like manner and the geometric hinge axis (32) extending in parallel to the rails.

7. A track cover according to claim 6, characterised in that the partial cover elements (31, 31') of each element pair are supported on each other at their rims (33, 33') which face each other, and with each partial cover element (31, 31'), along its rim that faces the other partial cover element of the respective pair, carrying sections (34, 34') and resting sections (35, 35') are provided in meander-like alternating succession, the resting sections (35) of the one partial cover element (31) of the re-spective pair resting on the carrying sections (34') of the oth-er partial cover element (31'), and the resting sections (35') of the other partial cover element (31') of the respective pair resting on the carrying sections (34) of the one partial cover element (31).
