Definitions
- the invention relates to a rail fastening according to the preamble of the claim 1.
- a resilient rail fastening is known for example from DE 196 08 823 A.
- Such rail fasteners are used on solid surfaces, like concrete, asphalt, but can also be mounted on sleepers.
- the rails rest on a threshold and are attached to the side Hold down clamps on the rail foot.
- the rail is embedded in Concrete has the disadvantage that the resilience of the resilient rail fastening is affected.
- the invention is therefore based on the task of fastening the rails at the beginning to create mentioned type, in which it is ensured that the resilience of the Rail fastening is retained.
- the invention advantageously provides that the clamping bracket of the rail fastening at least one chamber for receiving at least one compression spring having.
- the inclusion of the compression spring in a chamber enables the Compression spring can always act on the rail foot with the same tension. Heaped-up soil material or an embedding of the rail in concrete can Do not affect the spring travel of the compression spring, so that it is ensured that always the same, predetermined clamping force acts on the rail foot.
- the chamber enables the compression spring to be largely protected against corrosion. This also helps to maintain the original for many years Spring tension. The chamber also protects the compression spring against overload.
- the clamping bracket is on the base plate or the sleeper flange part through which the at least one sleeper screw is passed, and has a housing part that the at least accommodates a chamber with the compression spring.
- the clamp bracket thus consists essentially of a flange part through which the threshold screw is passed and a housing part in which the compression spring acting on the rail foot is accommodated.
- the chamber is closed at the top, so that no compression material or concrete can penetrate the compression spring.
- the after below open chamber is arranged above the rail foot, so that the The compression spring rests completely on the rail foot.
- the chamber has a predetermined depth so that the bias of the compression spring is limited to a predeterminable value. This also ensures that All clamps always apply the same amount of preload. But it can also clamp brackets with different chamber depth or Compression springs of different lengths are kept ready to target different ones To provide preload forces. Furthermore, clamp brackets can be used different flange geometries for setting the track width of the rails be kept ready. This is done, for example, with different flange widths between the hole for the threshold screw and the housing part.
- the chamber is a has a cylindrical shape.
- a spring ring can be used as a compression spring in this cylindrical chamber.
- the clamp can also have several chambers, each with its own Compression spring or a single chamber with several compression springs.
- the flange part faces away from the rail Side on an outer edge of the base plate running parallel to the rail is applied.
- the flange part can thus be supported on the base plate and enables an exact positioning of the rail relative to the base plate.
- the bottom surface of the housing part in contact with the rail base is on adjusted the inclination of the rail foot.
- the clamping brackets have elongated holes for the sleeper screws, which are at an angle ⁇ run to the rail foot or to the rail. Because the slots are oblique run, the relative position of the rail to the base plate by one of the Angle ⁇ and the length of the elongated holes dependent amount can be shifted. Thereby it is possible to increase the track gauge of the rails by a certain amount change. For example, there is a change in track gauge on each rail attachment possible by ⁇ 5 mm, so that the track width changes by a total of ⁇ 1 cm can be. This is advantageous to compensate for manufacturing tolerances or, for example, to set the track width differently in the curve areas.
- the clamping bracket and the base plate have adapted slinging means on, the slings also at the angle ⁇ of the elongated holes Close the clamp brackets together. In this way it is a concern of the Clamp bracket guaranteed against a stop even when the clamp brackets can be moved relative to the clamping screws and the base plate, to change the track position of the rail.
- the sling means the clamping bracket the outer edge running on the rail opposite side which is oblique at the angle ⁇ and against one of the Base plate protruding, inclined web rests.
- the fastening hole in the flange part of the clamp bracket consists of an elongated hole in one parallel to the rail base at an angle ⁇ to the rail runs obliquely.
- the sling means of the clamp brackets and the base plate also run parallel to the rail.
- Fig. 1 shows a cross section through a rail including the rail fastening.
- the rail 1 shown is a tram profile.
- the rail fastening serves to releasably connect the rail 1 to the ground.
- the rail can be fixed on the surface Place the plate or on sleepers 2.
- Fig. 1 shows a rail 1, the one running in the transverse direction of the rail Base plate 3 rests. Between the base plate 3 and the rail foot 4 of the rail 1, a damping plate 18, for example made of plastic, can also be arranged his. This damping plate 18 is used to make the rail 1 resilient on the base plate 3 record. You can also use damping plates of different thicknesses 18 the height position of the rail 1 can be adjusted.
- the rail 1 is covered in its lower part with a concrete layer 22.
- a concrete layer 22 On the Concrete layer 22 is a bituminous binder layer 24 and the top one Layer 26 consists of mastic asphalt.
- the clamping bracket 6 consists of a lying on the base plate 3 Flange part 14 and a compression spring 8 receiving housing part 16, which is preferably are integrally connected.
- a compression spring 8 receiving housing part 16 which is preferably are integrally connected.
- two sleeper screws 10 arranged through a bore in the flange part 14 and the base plate 3 in a threshold 2 or screwed into a solid surface made of concrete or a mineral mixture are.
- the sleeper screws In the case of wooden sleepers, the sleeper screws have 10 a wooden thread. In the case of concrete sleepers, the sleeper screws 10 pegged.
- the housing part 16 extends laterally from the flange part 14 in the direction of the Rail 1 and is designed so that it overlaps the rail base 4.
- the housing part 16 has two downwardly open in the embodiment of FIG Chambers 12, in each of which a compression spring 8 is arranged in the form of a spring ring is.
- the spring ring can be inserted into the chamber 12 with play, the height of the chamber 12 being adapted to the height of the compression spring 8 in such a way that the compression spring 8 consisting of a spring washer with a certain preload is pressed against the rail foot 4.
- the housing part 16 forms at the same time a stop, so that it is ensured that no excessive pressure forces be exerted and that the contact pressure on all clamping brackets 6 is equal to.
- the housing part 16 also prevents by sealing against Rail 1 that dirt or particles penetrate into the spring elements of the compression spring 8 can. In this way, the corrosion of the compression spring 8 is also reduced and thus extends their lifespan. In any case, it prevents concrete mass penetrates into the compression spring 8 and thus limits their mobility. It is therefore ensured that the tension force of the compression spring 8 even at one Pouring the rail base 4 with concrete 22 is retained since the housing part 16 the compression spring 8 receives completely and seals the compression spring to the environment.
- the chamber 12 is completely above of the rail foot 4, so that the compression spring 8 with its entire base can support on the rail base 4.
- the base plate 3 has at their longitudinal edges running parallel to the rail 1 in each case an upwardly projecting outer edge 20 on which the flange part 14 laterally is supported.
- Compression springs 8 can be arranged side by side or coaxially.
- the chambers 12 can be filled with grease for the corrosion protection of the compression spring 8 his.
- the figures 3 and 4 show a second exemplary embodiment of the rail fastening, in which the base plate 3 has a mounting hole 11 for receiving the threshold screw 10, which is adapted to the diameter of the threshold screw.
- the mounting hole of the clamp brackets 6 is an elongated hole 9, which below an angle of 10 to 25 °, preferably 15 °, runs to the rail.
- Under The rear outer edge 15 of the clamping bracket also runs at the same angle ⁇ 6, which bears against a web 21 projecting upward from the base plate 3, which also extends at an angle ⁇ to the rail 1.
- the angle ⁇ lies in a horizontal plane.
- the mounting hole of the base plate 3 is also an elongated hole 11, that runs obliquely to the rail 1 at the same angle ⁇ .
- the base plate 3 together with the two clamps located on it 6 in the direction of the longitudinal axes of the elongated holes 9, 11 the track position of the rail 1 relative to the threshold or relative to the second rail track to change.
- the outer edge facing away from the rail 1 15 of the clamping bracket 6 and the web 21 forming the stop surface in parallel run to rail 1.
- the stop for the clamp bracket also through a slot running parallel to the rail 19 be formed, in one of the flange part 14 of the clamp bracket 6 after protruding projection 21 engages below.
