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 hinge-like. At their facing rims (15, 16), the slabs (5, 6) 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). Upwardly directed indentations (22) shaped complementary to the carrying portions and originating from the slab lower side (21) being formed below the resting portions (18). The resting portions of the one slab rest on the carrying portions of the other slab, and the resting portions of the other slab rest on the carrying portions of the one slab. The slabs are preferably made of concrete and reinforced. |
