Abstract: A track cover comprising slab-shaped cover elements (7) arranged between the rails (3) of the track (2) on rail level and, preferably, also slab-shaped cover elements (8) outwardly adjoining the rails (3). The cover elements (7, 8) comprise supporting bodies (9) at their rims (10) which face the rails (3), the cover elements resting on the rails (3) by means of these supporting bodies. The supporting bodies (9) which are arranged on the cover elements (7, 8) at their rims (10) that face the rails (3) are mounted on these cover elements so as to be shiftable in the rail-longitudinal direction (11). It is suitable if on each rim (10) of the cover elements (7, 8) that faces a rail (3) which is provided with the cover, at least two supporting bodies (9) are shiftably arranged. Preferably, the supporting bodies (9) are mounted to be shiftable in the rail-longitudinal direction (11) and to be pivotable about a geometric axis extending in parallel with the displacement direction.

Abstract: A noise control device for tracks (1) comprising sound-absorbing slabs (3) mounted at the rails (2) of the track (1), the slabs being supported on the rails (2) via elastic sections (5) and self-supportingly bridging the space between the rails (2). To improve silencing of the slabs (3) it is provided for the slabs (3) to be comprised of particles (9) of porous lightweight building material, which are combined by a binder. The slabs (3) have an embedded reinforcement (11). Advantageously, also silencing cavity resonators (14) are formed in the slabs (3). A special embodiment provides for the space between the rails (2) of a track to be bridged by slab parts (3a, 3b) arranged in pairs which are supported on each other at their rims (26, 27) facing each other.

Abstract: A level cover for tracks (1), wherein the space (4) present between the two rails of a track is bridged by slabs (5, 6) arranged in pairs, which slabs are merely supported on the rails (2, 3) and bridge the distance (13) between the rails self-supportingly, the two slabs of the slab pairs being assembled in hinge-like manner. At their facing rims (15, 16), the slabs (5, 6) of each slab pair have carrying portions (17) and resting portions (18) alternatingly following each other in meander-like fashion, the carrying portions being formed by indentations (20) originating from the slab upper side (19) and extending as far as to the rim facing the other slab, upwardly directed indentations (22) originating from the slab lower side (21) being formed below the resting portions (18), which indentations are shaped complementary to the indentations of the carrying portions.

Abstract: In a track whose rails are laterally and downwardly supported on the rail outer side and on the rail inner side via elastic intermediate inserts (4, 6) by longitudinal carriers underneath the head portion (3), the rails (2) extend at a distance above the track structure parts located therebelow. The longitudinal carriers at the rail outer side are first console ledges (5) which are part of a base plate (10) lying under the rails (2), and the longitudinal carriers on the rail inner side are second console ledges (7) which are part of an inner plate (11) lying between the rails (2), which inner plate (11) in turn is supported on the base plate (10).

Abstract: A multi-track road crossing including a roadway positioned at the level of the rails, which roadway is formed by self-supporting slabs, wherein inner slabs (4) are provided which bridge the space between the rails (2, 3) of each track (G1, G2) and are supported on these rails (2, 3), and wherein outer slabs (6) are provided which are supported on the outer side of a rail (2, 3) of the track (G1, G2) by one of their sides (6a) and on a supporting body (10) arranged beside the track by the other one of their sides (6b). In the intermediate region (Z) between two tracks, the roadway is formed by self-supporting compensating slabs (11, 11a) which on both of their longitudinal rims (12) are supported on the supporting bodies (10, 10a) which also support the outer slabs (6) of the respective tracks (G1, G2). The compensating slabs (11, 11a) preferably are polymer concrete slabs, in particular made of polyester concrete.
