Abstract

A damping arrangement for tracks to be travelled over by rail vehicles having flanged wheels, including a) a rail, and b) an outer lateral profile of elastomer material which bears on the outer side of the rail at least in a region of a lateral outer rail head flank and in a region of an outer rail head underside, wherein the outer lateral profile has, in the region of the outer rail head underside and in the region of the lateral outer rail head flank, close to the rail, a soft region which is elastically resilient with respect to the rail head, and, in the region of the lateral outer rail head flank, remote from the rail, a substantially non-elastic hard region.

Abstract

A sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1), wherein the profile region (2) has, at least in one subregion (6), a non-woven, felted or random fibre layer (5) which is fixedly connected to the sealing profile (1) and which extend beyond the profile region surface (4).

Abstract

A rail assembly for rail vehicles having flanged wheels, in particular in the area of track covers and track crossings, as well as a profiled filling element therefor. The rail assembly (1) comprises a support structure (7) for a cover (9) which covers the space (8) directly alongside the rail (2), the cover (9) acting as a guide rail and being easy to remove from the support structure (7). Also disclosed is a profiled filling element (200, 220) particularly suitable for the rail assembly (1).

Abstract

A rail arrangement for rail vehicles furnished with flanged wheels. To reduce the risk of accident existing in connection with grooved rails, particularly for cyclists and pedestrians, a rail arrangement is provided including a. a rail (2) having a rail head (3), a rail web (4) and a rail base (5), the rail head (3) having a drive rail (6), a guide rail (7) and a rail groove (8) lying therebetween; and b. a filler profile (9) arranged in the rail groove (8).

Abstract

A sealing arrangement for shaft and tunnel constructions. The sealing of gaps between components of shaft and tunnel constructions is improved, in particular if the components are misaligned. For this purpose a) the sealing arrangement (1) comprises at least two components (2), which lie against each other at butt sides (3) so as to form a gap (4), b) the components (2) have an elastic sealing profile (5) on each butt side (3), and c) the sealing profiles (5) of the butt sides (3) that lie against each other lie against each other on a contact plane (6) and bridge the gap (4) in a sealing manner. The sealing profiles (5) have areas (7, 8) of different hardness arranged in alternation in the transverse direction (9) perpendicular to the respective profile longitudinal plane (10), the sealing profiles (5) of butt sides (3) that lie against each other differing from each other in the arrangement of the areas (7, 8) of different hardness in the transverse direction (9).
