Description

The invention relates to arrangements of intersecting or intersecting tracks for rail vehicles. In particular, the invention relates to switches, intersections or crossing points for rail vehicles.

It is known to provide concrete sleepers for tracks for rail vehicles on the underside with a Besohlung of plastic, in particular an elastomer. These concrete sleepers are embedded in a ballast bed. A well-known sleeper pad is off EP-A-1 298 252 known. The concrete sleepers under points, crossings or intersection points, so under track arrangements of intersecting or intersecting tracks for rail vehicles are provided on the underside with elastic plastic Schwellenhleohlungen.

The use of soled barrier undulations and comparable track structures of intersecting tracks provides much greater effect on these highly stressed components than on application under normal (range) thresholds than outside of these designs. When dimensioning sleepers for switch points and / or crossing sleepers, therefore, far more influences must be taken into account than outside turnouts / intersections.

In previous applications of soles under points and / or crossing thresholds, the elasticities of the soles are staggered such that the soling each have a plurality of successive thresholds have a uniform elasticity and then be used in a subsequent area threshold insoles with other elasticities.

In the central region of the arrangement of intersecting or intersecting tracks, ie in the region of the heart of a switch or a track arrangement in the rails V-shaped to run towards each other, long sleepers are used, which carry at least two gradually diverging tracks. Following this central area with long sleepers, a first section follows per track, in which the track in question is supported by short sleepers. The first sections are followed by second sections in which the two tracks are each supported by normal sleepers. The Kurzschwellen are shortened due to baugeometrischen reasons on the respective track inner sides, so there have a shorter sleeper head than on the outer sides of the track. The threshold projection on the inner sides of the track is thus lower than on the outer sides of the track, with which these short sleepers are arranged asymmetrically to the tracks. In the shortened ends (sleepers) of the short sleepers occur due to the lower contact surface higher surface pressures under the short sleepers. These higher surface pressures can be compensated in a known manner by Schwellenfersohlungen in which several sole parts are applied with different elasticity / stiffness on the short sleeper underside. An example of this procedure is in EP-A-1 857 590 described.

The aforementioned procedure requires special handling in the application of the threshold solders and thus requires a separate production of these short-sleeper solders. There is also the possibility of confusion of Schwellensohlenteilen.

The object of the invention is to provide the sleeper padding in the area of the arrangement of intersecting or intersecting tracks for rail vehicles, such as e.g. To simplify switches, crossings or crossroads in several respects.

• – mindestens zwei zueinander benachbarten Gleisen, von denen jedes eine Innenschiene und eine Außenschienen aufweist, die auf in einem Schotterbett ruhenden Schwellen mit zwei stirnseitigen Schwellenköpfen und unterseitiger Besohlung befestigt sind,
• – wobei die einander zugewandten Innenschienen in einem Zentralbereich V-förmig verlaufen,
• – wobei die beiden Gleise im Zentralbereich auf gemeinsamen Langschwellen, in an den Zentralbereich jeweils angrenzenden ersten Abschnitten auf Kurzschwellen, die kürzer sind als die Langschwellen, und in auf die ersten Abschnitte jeweils folgenden zweiten Abschnitten auf Normalschwellen, die länger sind als die Kurzschwellen und kürzer sind als die Langschwellen, befestigt sind,
• – wobei die Kurzschwellen symmetrisch zu den ihnen jeweils zugeordneten Gleisen angeordnet sind, indem die Schwellenköpfe jeder Kurzschwelle gleichermaßen weit über die betreffenden, von den Kurzschienen getragenen Innen- und Außenschienen überstehen, und
• – wobei die Besohlung jeder Kurzschwelle eine über ihre Erstreckung gleich Elastizität und/oder Steifigkeit aufweist.

To solve this problem, the invention proposes an arrangement of intersecting or intersecting tracks for rail vehicles, such as switches, crossings or intersection points, wherein the arrangement is provided with

• - at least two mutually adjacent tracks, each of which has an inner rail and an outer rail, which are mounted on sleepers resting in a ballast bed with two end-side sleeper heads and underside soles,
• - wherein the mutually facing inner rails in a central region V-shaped,
• - Where the two tracks in the central area on common long sleepers, in the central area respectively adjacent first sections on short sleepers that are shorter than the long sleepers, and in each of the first sections following second sections on normal sleepers that are longer than the short sleepers and shorter are attached as the sleepers,
• - Where the short sleepers are arranged symmetrically to their respective associated tracks by the threshold heads each short sleeper equally well beyond the relevant, supported by the short rails inner and outer rails, and
• - wherein the soling of each short sleeper has an elasticity and / or rigidity over its extension.

In accordance with the invention, the short-sills required by the baugometry, which are used in the first sections of the two gradually diverging tracks, are each arranged symmetrically to the respective track, so that they both equally well on both the track inner sides and on the track outer sides, these projections are smaller than in the normal thresholds and / or at the long sleepers of the track assembly. Due to the symmetrical arrangement of the short sleepers under the at least two in each other or diverging or intersecting tracks of the track arrangement according to the invention, the surface pressure equalized under the short sleepers to the ballast bed. As a soling of this inventively arranged short sills now a Schwellenleohlung can be used with over their extent constant elasticity and / or rigidity. Faulty arrangements of the Kurzschwellenhleohlungen or a faulty installation due to incorrect alignment of the short sleepers are therefore no longer possible. This simplifies the handling of the sleeper padding and its application on the short sleepers.

To compensate for the increased surface pressures in the region of the short sleepers can be provided to arrange these short sleepers each track at a smaller distance from each other, as is the case with the normal and / or long sleepers of the track in question.

Alternatively or additionally, it can be provided in a further embodiment of the invention that the stiffness and / or elasticity of the soling of a short sleeper is different from the stiffness or elasticity of soling a long and / or normal threshold, wherein the stiffness of the soling of a short sleeper greater is as that of soling a long and / or normal threshold and / or wherein the elasticity of the soling of a short sleeper is less than that of soling a long and / or normal threshold.

The invention thus an asymmetric surface pressure under soled turnout or crossing rails in the connection area to the sleepers is prevented by the short sleepers used in the connection to the sleepers are not one-sided but reduced on both sides with respect to their length (compared to normal thresholds), the threshold heads of the short sleepers so evenly on both sides of a track (but shorter than the normal thresholds) survive.

The invention will be explained in more detail using an exemplary embodiment and with reference to the drawing. In detail, they show:

1 a plan view of a track arrangement of interlocking tracks for rail vehicles in the form of a switch and

2 a side view of one at the switch to 1 short-sleeper used at their threshold heads around the ends shown in broken lines with respect to a normal threshold, as in the switch to 1 be used outside the short- and long-sleeper areas as well as on the free route normally shortened.

In 1 is a switch 10 shown the first track 12 and a second track 14 has, which diverge or diverge. The soft 10 has a central area 16 on one side the two tracks 12 . 14 run and to the opposite other side another track 18 extends.

The construction according to the invention relates to that region which, based on the illustration in FIG 1 right from the central area 16 is shown and in which the two tracks 12 . 14 gradually diverge or (depending on the viewing direction) run into each other.

In this area, every track points 12 . 14 a first section 20 . 22 on, both to the central area 16 adjoin. At these two first sections 20 . 22 closes in each case a second section 24 . 26 at. In the central area 16 shows the switch 10 long sleepers 28 on, which are different lengths and especially longer than normal thresholds 30 are under the track 18 as well as in the second sections 24 . 26 under the two tracks 12 . 14 are arranged. The two tracks 12 . 14 each have an outer rail 32 and an inner rail 34 on, with the two inner rails 34 in the central area 16 the switch 10 to the heart 36 towards V-shaped. The two tracks 12 . 14 So are each through an outside 38 and an inside 40 defined, with the two insides 40 facing each other.

The normal thresholds 30 (and also the sleepers 28 ) are arranged substantially symmetrically to the rails carried by them, so are symmetrical over to both track sides. In that regard, the long sleepers 28 and the normal thresholds 30 each equally protruding threshold heads 42 . 44 on.

The special feature of the switch 10 according to 1 consists in the arrangement of short sleepers 46 within the first sections 20 . 22 under the first and second tracks 12 . 14 , These short sleepers 46 have a shorter length than that of normal sleepers 30 the case is. The normal thresholds 30 In turn, their length is shorter than the sleepers 28 ,

According to the invention are now the short sleepers 46 symmetrical under the track concerned 12 . 14 arranged. Your threshold heads 48 . 50 are thus opposite the threshold heads 42 . 44 the normal thresholds 30 or the sleepers 28 shortens, as in 1 can be seen. 2 shows this as well, where in a solid line the short-sleeper 46 with their compared to normal thresholds shortened sleepers 48 . 50 is shown. Dashed is in 2 the opposite to a short-sleeper 46 longer sleeper head 42 . 44 shown at the front ends of a normal threshold.

In 2 is also shown that the short sleepers with a soling 52 are provided. Such soles are also below the normal thresholds 30 and the sleepers 28 the switch 10 according to 1 , Each threshold soling 52 has a particular elastomeric plastic layer 54 on. Such threshold solders made of elastomeric plastic are basically known and will therefore not be described in detail here.

By inventively provided symmetrical arrangement of the short sleepers 46 have these in their threshold head areas the same surface pressure to (not shown) ballast bed in which all thresholds of the switch 10 are embedded on. This requires it as a soles 52 a plastic layer 54 extending along its entire length along the short sleeper 46 has a uniform elasticity or rigidity. Thus, these parameters do not have to change gradually, which is the production of the threshold soling 52 and their handling during assembly on a short sleeper 46 facilitated.

In summary, the invention can thus be described to the effect that according to the invention used in the baugeometrisch limited spaces behind the sleepers short sills are not only shortened to the respective neighboring track out but are shortened on both sides and thus experience a so far symmetrical length reduction. With these symmetrically shortened short-sleeper, the asymmetric loads occurring with one-sided shortened short-sleeper are excluded. The gradation of elasticity / rigidity required for one-tailed short-sleeved over the threshold length is not required. The shortened on both sides short-sleeper can be equipped with standard soles, so with sediments for normal sleepers. The elasticity of these standard solders is determined by the top design or dimensioning of the sole type. To avoid a comparison with the adjacent sleepers and / or the also adjacent normal sleepers (thresholds with standard length) increased ballast pressure the shortened short-sleeper with a reduced compared to the normal thresholds and sleepers threshold distance can be installed.

The production of a short sleeper of concrete can be conveniently realized with a formwork, as it can also be used for the production of normal sleepers. For producing a short sleeper, such a formwork is designed to have fillers on its opposite narrow ends, so that a short sill is created by pouring out the interspace of the formwork between the filling pieces and after hardening of the concrete. As with the production of normal sleepers, the short sleepers can of course also be made of prestressed concrete or limp-reinforced. As a type of short-sleeper is also a half-threshold, as is known from normal thresholds.
