Definitions
- the invention relates to a railway sleeper, as used for the laying of rails and tracks.
- Railway sleepers generally have rail support areas arranged at their ends, within which the rails are fixed at their rail feet by hold-down elements. In order to be able to absorb horizontal forces in the horizontal direction along the extent of the railway sleepers (that is to say transversely to the extent of the rails), it is known to widen the rail contact areas. Examples of such railway sleepers can be found in DE-A-100 23 389, DE-A-27 35 797, DE-A-21 55 479, US-A-1 555 662 and US-A-1 406 454.
- the object of the invention is to improve the support and fixation of rails on railway sleepers with widened Schienenetziage Symposiumen.
- a levitation body having at each of its opposite ends a rail support area within which the threshold body is widened, wherein a rail can be fixed in each rail support area by means of a hold-down element which can be attacked by a rail foot.
- the invention provides
- each rail support region has three rail support surfaces adjoining each other in the extension of the rail, that at least one hold-down element is arranged between and above at least one sub-region of respectively adjacent rail support surfaces of each rail support region and that the sleeper body is free of Verstetfungs instituten within each rail support region on both sides of the spaces between adjacent rail support surfaces.
- each widened ienenchienenetziageber etch on three rail support surfaces, which are arranged side by side in extension of the rail.
- These three rail support surfaces are formed, for example, as flat, lying in a plane surfaces that are raised relative to their environment.
- the resting on the rail support surfaces rail spans the spaces between adjacent rail support surfaces.
- the hold-down elements are arranged such that they are located above the area between in each case two adjacent Schienenauflagefiambaen and protrude over these adjacent rail support surfaces. This results in a reliable holddown of the rail feet on each of the three rail support surfaces, in each case at one end of the threshold body, the rail foot rests flat and planar on all Schienenetziage lake.
- the hold-down elements according to the invention can therefore be "gap" to arrange the rail support surfaces and secure, because in these areas on both sides of the spaces between adjacent rail support surfaces no reinforcing (reinforcement) Eleme ⁇ te in Lying bodies are located.
- Such stiffening elements are used for bracing or reinforcing the sleeper body, in particular when using concrete.
- two or four hold-down elements may be provided per group of rail support surfaces.
- They are used as Niederhaiteelernente the known spring clips, so their fastening screws can be located laterally of the gap between each two adjacent Schienenetzlagefi Stahlen.
- other hold-down elements which are fastened with screws, can be connected at these points via the screws with the threshold body. If four hold-down elements are used per triad of Schienenetzlagefi Stahlen, so are each two hold-down elements in pairs opposite. If only two hold-down elements are used, they are arranged diagonally opposite one another.
- the sleeper body has a greater extent transversely to its longitudinal extent.
- at least one first stiffening profile element extends below the rail support areas within the threshold body.
- This stiffening profile element is expediently arranged substantially centrically to the rail axis; If a plurality of stiffening profile elements, which then preferably run parallel to one another, are used per rail contact area, then these several stiffening profile elements are arranged symmetrically and centrically to the rail axis.
- a fairly good stiffening of the widened rail contact areas can be realized by using a profile which has a leg extending substantially at right angles to the rail support surfaces as the stiffening profile element.
- the stiffening profile element For example, as stealth profile element used an angle profile, T-Profii or U-profile.
- the threshold body is particularly useful to execute the threshold body as a two-block sleeper body.
- the two blocks are interconnected by a second reinforcing profile element.
- This second stiffening profile element in turn is in turn connected to the first stiffening profile elements.
- the two-block threshold thus has a stiffening frame made of the second stiffening profile element and the two first transverse profiling elements extending transversely thereto at the ends of the second stiffening profile element, the crossing / connecting points of the stiffening profile elements being located below the middle rail seating surfaces. This also applies if the threshold body is designed as a monoblock and has at least one second stiffening profile element.
- the plastic blocks should be able to move relative to the stiffening frame from the second stiffening profile element and the first stiffening profile elements, since plastic has a greater temperature coefficient than Metaü, which is used for the stiffening profiles.
- the stiffening profiles (longitudinal and / or stiffening profile elements) smooth upper have surfaces over which the plastic can "push" in its expansion or in its contraction after expansion.
- the first stiffening profile elements since they are arranged centrically to the rails, provide for a centering of the rail support areas, so that they can not move relative to the rails transversely thereto.
- the reinforcing profile elements with legs extending preferably at right angles to the rail support surfaces, ensure a fixation of the rail support areas, which in the case of a plastic sleeper are made of plastic, below the rail feet.
- the second stiffening profile element between the two blocks is further provided to protect the second stiffening profile element between the two blocks from corrosion in the case of a two-block threshold.
- the area of the second stiffening profile element between the two blocks with a plastic foam, preferably a PU sheathing, is surrounded or foamed.
- the foam has the advantage that it follows in an expansion of the blocks, if they are made of plastic, or follows the temperature-induced movement of these blocks.
- a receiving groove or - depression are formed for receiving a line conductor, which is prescribed for safety reasons for train control at higher speeds approved routes.
- FIGS. 2 and 3 show alternative ways of fastening rails with either two pairs of hold-down elements or only two hold-down elements per rail;
- FIGS. 4 to 7 are partial perspective views of the stiffening rib of the railway sleeper
- Fig. 8 is a plan view of the railway sleeper with arranged between the blocks, the stiffening enclosing plastic foam and
- the erfi ⁇ dungssiee railway sleeper will be described below with reference to their execution as a two-block threshold made of plastic.
- plastic As a material in particular recycled plastic is used. This is available in very large quantities and ideally suited for this application. In addition, this material can be used to develop an excellent cycle, which is particularly environmentally friendly.
- recycled plastic obtained from the old sleepers can also be used for other missions.
- the two-block connection is produced, for example, by an angle iron, a T-profile, a tubular profile or a double I-profile.
- other materials are conceivable, such as carbon, fiberglass, Keflar, etc.
- the total length of the railway sleeper can be any individual such as 2.25 m, 2.40 m, 2.60 m or other desired lengths for a variety Track tracks are produced.
- the two-block mold was chosen to create a non-contact zone in the middle of the track, so that no "riding" of the sleepers occurs in the middle of the track.
- the connecting element of the two blocks of steel in a wide variety of shapes or other materials will be beyond the bearing area of the rails and the fastener performed. From this construction it follows that no central attachment to the thresholds arises. This is wanted.
- the threshold width is derived from the opening dimension of the tamping machine. This is preferably a measure of about 350 mm wide.
- the threshold thickness should preferably be 160 mm. This is an adaptation to the many existing tracks made of wooden sleepers. In this way, it is achieved that, when converting the existing track from hoist sills, there is no need to carry out any lowering of the level, as is the case, for example, when converting from wood sleepers to concrete sleepers.
- Wood 160 mm concrete «210 mm.
- a broadening of the threshold under the rail is provided.
- Each of the two blocks 14 has a rail support region 16 with three successively arranged rail support surfaces 18, which are separated by gaps 20 from each other.
- the enlarged Schtenenauflage Schemee 16 are laterally beyond the blocks 14 and are stiffened by reinforcing profiles 22.
- These reinforcing profiles 22 are centered on the rails 24 (see also Figures 2 to 7) and are rigidly connected to the ends of a longitudinal profile 26.
- the longitudinal professional! 26 connects the two blocks 14 of the two-rocker body 12 with each other.
- the threshold below the rails results in the greatest possible resistance surface against the horizontal forces. Furthermore, an almost continuous bearing of the rails can be achieved by broadening the threshold. As a further advantage, this construction can be used to design a very favorable double bearing of the rail on the threshold, as e.g. where Y-Stahishwe! le is known. A triple bearing of the rail is also to be constructed from this arrangement.
- FIG. 2 shows the situation where per rail 24 and threshold block
- the push-through resistance of the rails is essentially determined by the size of the clamping forces in the rail fasteners, as these give rise to the friction forces between rail and sleeper. This push-through resistance is
- the erf ⁇ ndungssiee embodiment has a preferred distance between the Querschwelienachsen of 60 cm to 90 cm. This results in gullet dimensions which make it possible to use the threshold even in tight bends and thereby optimally remove the load from the vehicle run on the substructure and in the horizontal.
- the type of weld construction allows the threshold distance to be separated, such as, for example, from one another.
- Figs. 4-7 As a longitudinal profile 26 is in the embodiments according to FIGS. 4, 5 and 7 uses an "upside down" angle profile, while in Fig. 6 a pipe is used.
- T-, U- or L ⁇ profiles are used, as shown in FIGS. 4-7 is shown. Decisive here is that these profiles are arranged such that they have at right angles to the rail support surfaces 18 extending legs 30.
- These legs 30 are either centrally centered to the rails 24 or they are (in the case of the U-profiles ofwhosbeispieie according to Figures 5 and 6) arranged symmetrically to the central axis of the rail 24. In all these cases, but especially in the case of using the U-profile with the rail centric alignment as shown in FIGS.
- a PU foam 32 is conceivable, which is shown in FIGS. 8 and 9 is shown.
- the plastic foam 32 brings with it possible thermal expansion movements of the two blocks 14, which can occur if these blocks consist of Kunststoffmateriai.
- the blocks 14 of, for example, plastic material are, however, centered by the special reinforcing profiles 22 below the rails 24, so that the rail support areas 16 do not move relative to the rail 24 with a possible réelleausdehnu ⁇ g the blocks 14 or do not move these rails.
- FIGS. 8 and 9 Another advantage of the plastic foam 32 is the fact that in it a receiving recess 34 may be introduced, as shown in FIGS. 8 and 9 is shown.
- This receiving recess 34 serves, for example, to receive a line conductor (not shown).
- the material for the blocks 14 is made of recycled plastic on both sides. This material is extensively available and important for further material circulation. With this material, the desired strength is achieved. It has the following material properties, which can be used by controlled processes:
- Body shock absorbing - can be reinforced with steel profiles
- the threshold weight can be optimized to reduce lift-off forces.
- the color scheme of the threshold can be easily influenced. ⁇ for example for temperature control, marking purposes.
- Fire protection can be optimized.
- the material is absolutely insensitive to moisture.
- Rail bearing designs can be molded.
- the material can be sawed, drilled or milled without special tools,
- the special features of the new threshold type are:
- Rail fastening constructions Constructive design of rail double supports, rail triple supports, - staggered bracing of the rail, double bracing in a slosh head.
- a derailment protection angle 36 can be mounted in appropriate dimensioning on the respective inner side of the rails (see Fig. 8).
- derailment protection angles 36 are to be provided when the threshold is used in derailment-sensitive areas, such as, for example, runoff mountains or maneuvering groups Since the recycled Materiai plastic used has similar properties as a wooden sleepers, this wooden threshold is still used today as an exception in runoff mountains and there is derailing sensitive to a certain extent, the use of the new threshold in these areas is particularly interesting.
- the features of the new type of threshold described above can also be achieved with the material concrete.
- the concrete - in addition to the Stahlprofilteiien - should be reinforced with fibers (glass fibers, steel fibers or plastic fibers).
- a further reinforcement is to be achieved here by the insertion of a limp reinforcement.
- the rail fastening screws are to be provided in this construction in preciselybetonierende, known plastic dowels.
- the new carbonization construction allows for a required load-bearing surface
