Definitions
- the invention relates to a fastening of rails on Y steel sleepers according to the preamble of patent claim 1.
- Such rail fastenings must have a special design, since Y-steel sleepers, in contrast to other sleepers, have a flat rail support and the distance between two I-beams is usually used to fasten the rail.
- DE 35 21 673 C2 shows such a rail fastening, in which the rail foot is clamped to the threshold via spring clips and in which an inclination plate and a damping plate are arranged on one another between the rail and the threshold. It is customary to bring the sleepers together with the rail fastening to the construction site in such a way that the tensioning clamps are pushed back so far that there is a free passage from above for inserting the rail.
- a disadvantage of the rail fastening according to DE 35 21 673 C2 is that not all parts of the rail fastening are held in this - preassembled - state, so that individual parts can be lost during transport or can only be assembled at the construction site .
- the invention is based on the object of developing a rail fastening for Y steel sleepers of the known type in such a way that all parts are securely held in the preassembled state with the tension clamps retracted, without additional components or measures being necessary for this.
- FIG. 1 shows the top view of a track laid on Y sleepers
- FIG. 2 the detail "A" relating to the rail fastening
- Figure 3 shows a section III-III through Figure 2
- FIG. 4 shows a section IV-IV through FIG. 2.
- Y steel sleepers 1 for the construction of tracks.
- These Y-steel sleepers consist of a plurality of I-profile supports 2 welded to one another. At the fastening points for connecting the rails 3 to the sleepers 1, the I-profile supports 2 have gaps 4 running in the direction of the sleepers.
- Figure 1 shows such a track.
- Figures 3 and 4 show different sections through Figure 2.
- the dowels 6 are supported from below against the upper straps of the I-section beams 2.
- the sleeper screws 5 clamp the rail 3 via spring clips 7 with the sleeper.
- the spring clips 7 resiliently rest on the rail foot 8.
- the ends of the Y-steel sleepers 1 are composed of two I-section beams 2.
- stop strips 12 which extend over the sleeper surfaces 9, also serve to transmit the rail side forces to the sleeper.
- the rail 3 is supported laterally with the edge of the rail base 8 against the stop strips 12 via the support blocks 10.
- the rails 3 have an inclination towards the center of the rail.
- an inclination plate 13 is placed under the rail. This inclination plate 13 engages with a central web 14 in the gap 4 of the Y-steel sleeper 1 and is thereby secured against displacement in the longitudinal direction of the rail.
- a damping plate 15 is inserted between the inclination plate 13 and the rail base 8 in order to achieve the intended damping between the rail and the ground, in particular when the Y steel sleepers 1 lie on a solid roadway.
- the inclination plate 13 has lateral upward side walls 16 on both sides, which laterally encompass both the damping plate 15 and the rail foot 8. This measure on the one hand prevents the damping plate 15 from migrating sideways. On the other hand, this measure gives the track better torsional stability between the sleeper and the rail.
- the side walls 16 are interrupted in the middle in order to allow the support blocks 10 to rest against the rail base 8 and the spring clamps 7 to function.
- Inclination plate 13 and damping plate 15 have a greater width than the rail base 8, so that they protrude laterally from the rail base 8.
- the support blocks 10 are taken out accordingly, so that the inclination plate 13 and the damping plate 15 overlap lugs 17 are formed at the level of the rail foot 8.
- the dowels 6 not only pass through the gap 4 with a web 18 but also have an extension 19 which projects beyond the threshold surface 9 and engages in a corresponding recess in the support blocks 10.
- the support block 10 and the dowel 6 are fixed to one another, so that the sleeper screws 5 are screwed in straight.
- the inner and outer rail support blocks 10 have a different height. Appropriate marking of such support blocks is common.
- the dowels 6, the support blocks 10, the inclination plate 13 and the damping plate 15 are preferably made of plastic, which meets the corresponding requirements.
- the spring clamp 7 is twisted or withdrawn from the middle of the rail in such a way that there is free passage between the lugs 17 of the support blocks 10 and above is available, through which the rail can be inserted undisturbed from above or removed upwards.
- the sleeper screws 5 are slightly tightened and press the spring clips 7 onto the support blocks 10. Since the support blocks 10 overlap both the inclination plate 13 and the damping plate 15 with a nose 17, these plates cannot detach from the sleeper surface 9. A lateral pushing out of the inclination plate 13 in the longitudinal direction of the rail is prevented by the web 14 engaging in the gap 4.
- the alignment of the rail height position can be carried out in a known manner by placing height compensation plates (not shown in the drawing) between the threshold surface 9 and the inclination plate 13 and support blocks 10. Due to the required function, these compensating plates must be divided in the middle and inserted on both sides. The web 14 of the inclination plate 13 and the extension 19 of the dowels 6 must then be made high enough to perform the functions described.
