Description

The present invention relates to a system, a method and a threshold for holding a rail.

Such systems for holding a rail are well known in the art and serve for the alignment and attachment of rails over which a train travels in the mounted state. In this case, each two rails are aligned with formation of a gap between them substantially parallel to each other along a rail longitudinal direction and extend over a plurality of thresholds, of which they are respectively held. Essential components of the systems for holding the rail are the threshold and an intermediate layer. The intermediate layer is typically arranged between the threshold and the rail in order to guide the occurring forces as evenly as possible into the sill during the passage of the train. Furthermore, the intermediate layers are designed such that they serve for a provision of the rail after the passage of the train.

Against this background, the present invention has the object of improving the systems for holding the rail, in particular with regard to their costs.

This object is achieved by a system according to claim 1, an arrangement according to claim 8, a method according to claim 9 and a threshold according to claim 10. Further advantages and features of the invention will become apparent from the dependent claims and the description and the accompanying figures.

According to the invention, a system for holding a rail is provided, comprising a sill and an intermediate layer which is arranged in an assembled state between the sill and the rail and whose extension in the transverse direction of the rail is smaller than a width of the rail measured in the transverse direction of the rail, wherein in the assembled state the intermediate layer is arranged under an edge region of the rail. In contrast to the prior art, the system according to the invention dispenses with an intermediate layer or an interlayer section in a central region, viewed below the rail, in the transverse direction of the rail. As a result, can be dispensed with material in the production of the thus formed intermediate layer. In this case, the invention makes advantageous advantage of the fact that the areas below the edge regions of the rail experience the greatest part of the stresses during the passage of the train. Finally, during a crossing of the train, the rail is pivoted or rotated about a pivot axis extending parallel to the rail longitudinal direction. This rotation is in particular outward, ie seen in the direction of travel in the clockwise direction for the right rail and counterclockwise for the left rail. As a result, the edge region, in particular the outer edge region is pressed into the intermediate layer. It has been found to be advantageous that it is possible to shorten the intermediate layer in its extent along the transverse direction of the rail, without restricting its functionality appreciably, if they are arranged below the edge region, since they derive here the outgoing of the tilting of the rail loads can. Preferably, it is provided that the intermediate layer is dimensioned such that in the assembled state, a region which is below the pivot axis in a direction perpendicular to the rail longitudinal direction and the rail transverse direction, remains free of material. This is advantageously dispensed with in the area on material or on the intermediate layer in which an influence on a force distribution during the crossing of the train is small or negligible. The edge region is understood in particular to be that region which, viewed in the transverse direction of the rail, adjoins a termination surface delimiting the rail and extends along the transverse direction of the rail up to a 0.3 times, preferably up to a 0.25 times, and particularly preferably up to 0.2 times, a width of the rail dimensioned in the rail transverse direction. Preferably, it is provided that the edge region is bounded by the central region, for example, as the central region of the region is understood, in a direction perpendicular to the rail longitudinal direction and perpendicular to the rail transverse direction below a rail head, ie a part of the rail on which the wheel the train is applied during the crossing, is arranged. In this case, under an arrangement under an edge region, both a flush termination with the end face of the rail and an arrangement staggered in relation to the end face in the direction of the central region are conceivable. Preferably, it is provided that the intermediate layer is arranged below the outer edge region, wherein the outer edge region extends on a side facing away from the intermediate space between the rails.

Conveniently, a further intermediate layer is provided, which is arranged in an assembled state between the threshold and the rail and whose extension in rail transverse direction is smaller than a width measured in the rail transverse direction width of the rail, wherein in the mounted state, the further intermediate layer opposite to the edge region in the rail transverse direction further edge region of the rail is arranged. As a result, the inner edge region of the rail can be supported by means of the further intermediate layer. It is envisaged that seen in the transverse direction of the rail, the area between the intermediate layer and the further intermediate layer remains free of material, ie it forms a space between the intermediate layer and the further intermediate layer. The free space preferably extends over the entire extent of the threshold in the rail longitudinal direction. Free space is understood to be, in particular, a material-free intermediate area between the threshold and the rail.

Preferably, it is provided that the intermediate layers and / or the further intermediate layer is offset relative to the end surface of the rail in the direction of the central region. In particular, the intermediate layer and the further intermediate layer are offset differently far in the direction of the central region. Preferably, the intermediate layer and the further intermediate layer seen in the transverse direction of the rail are arranged asymmetrically with respect to a mirror plane, wherein a pivot axis runs through the mirror plane about which the rail tilts when crossing a train. As a result, due to the different arrangement, consideration can be given to the different loads. Furthermore, it is conceivable that only the intermediate layer or the further intermediate layer is offset relative to the end surface of the rail in the direction of the central region.

Preferably, the intermediate layer and / or the further intermediate layer are designed strip-shaped.

The intermediate layer and / or the further intermediate layer may be made of an elastomeric material, such as NR (natural rubber), SBR (styrene-butadiene rubber), EPDM (ethylene-propylene-diene rubber) and / or PUR (polyurethanes) or a thermoplastic material , such as PE (polyethylene), PP (polypropylene), EVA (ethylene vinyl acetate) and / or TPE (thermoplastic elastomer) may be formed. For example, the intermediate layer and / or the further intermediate layer is compact, shaped and / or foamed. Furthermore, it is preferably provided that the intermediate layer and / or the further intermediate layer is designed as a function of the expected loads and, for example, a material composition of the intermediate layer and / or the further intermediate layer for straight-line sections differs from that for curved sections.

Preferably, a ratio between an extension of the intermediate layer and / or the further intermediate layer to the width of the rail takes a value between 0.03 and 0.4, preferably between 0.06 and 0.35 and particularly preferably between 0.10 and 0, 3 on. It has been chosen for a sizing between 0.1 and 0.3 pointed out that despite the comparatively narrow sizing a permanent and effective power dissipation can be realized without a lifetime of the intermediate rail position is significantly reduced. For example, the intermediate layer and / or the further intermediate layer has an extension of 15 to 45 mm, measured in the transverse direction of the rail, for a UIC 60 rail with a width of 150 mm. The intermediate layer and / or the further intermediate layer preferably extend in the rail longitudinal direction over a length of 30 to 250 mm, preferably from 100 to 180 mm.

In particular, the intermediate layer and the further intermediate layer are arranged mirror-symmetrically to a mirror plane, wherein a pivot axis runs through the mirror plane about which the rail tilts when crossing a train. For example, the intermediate layer and the further intermediate layer in the transverse direction of the track terminate flush with the end surface or are offset by the same distance from the end surface in the direction of the central region. Preferably, the intermediate layer and the further intermediate layer are identical, in particular with regard to shape and material composition configured. In the case of a flush contact with the end face, the intermediate layer and / or further intermediate layer can be fixed to a side against a lateral displacement, for example, by abutment against an angle guide plate adjoining in the transverse direction of the rail.

Appropriately, it is provided that the system has a means for fixing the intermediate layer and / or the further intermediate layer against an offset in the transverse direction of the rail. This advantageously prevents the intermediate layer and / or the further intermediate layer from shifting in the direction of the central region over time. It is conceivable that the means for fixing against an offset at the intermediate layer or the further intermediate layer and / or is applied to the threshold. For example, the means for fixing the intermediate layer for a positive, non-positive and / or material connection between the threshold and the intermediate layer provides. It can do that Means for fixing the liner against an offset also part of the liner and / or threshold to be. In particular, the agent determines the functional arrangement of the intermediate layer or the further intermediate layer. Furthermore, it is preferably provided that the system has a further means for fixing the intermediate layer or the further intermediate layer against an offset in the rail longitudinal direction. For example, the intermediate layer or the further intermediate layer extends in the longitudinal direction of the rail over the threshold and encompasses the threshold for a positive connection in the rail longitudinal direction, for example by means of corresponding legs or projections at the ends of the intermediate layer or the further intermediate layer.

Preferably, the means for fixing the intermediate layer and / or further intermediate layer is a depression and / or a raised portion on an upper side of the sill facing the rail and / or an angled guide plate. By means of a depression, a simple positive connection in the transverse direction of the rail can be provided. For this purpose, the recess is preferably dimensioned such that the intermediate layer and / or the further intermediate layer can be used accurately. As a result, for example, in the sense of a key-lock principle, it is possible to avoid inadvertently using an inappropriate intermediate layer and / or further intermediate layer. Preferably, a depth measured perpendicular to the transverse direction of the rail and the longitudinal direction of the rail assumes a value between 0.2 and 18 mm, preferably between 0.23 and 15 mm and particularly preferably between 0.5 and 12 mm. Also conceivable as a means for fixing is a groove structure, wherein grooves of this groove structure can be designed to be continuous or interrupted. For example, the individual grooves are 2 to 10 mm wide (in the rail transverse direction) and 0.5 to 12 mm high (perpendicular to the rail longitudinal direction and rail transverse direction). In particular, by the height of the groove structure, preferably a height between 0.5 and 12 mm, the intermediate layer can be secured against rotation. It is also conceivable that the intermediate layer is fixed by means of a frame, wherein the frame is connected in the assembled state to the threshold. Preferably, the frame has a height between 0.5 and 12 mm. In the case of an increase, it is conceivable that the liner or the further intermediate layer can be dimensioned thinner. With an angled guide plate can be dispensed with advantageously on a surface structuring in the threshold below the rail. Preferably, the intermediate layer, in particular a portion below the angle guide plate, jammed. It is conceivable that the angle guide plate and the intermediate layer in the assembled state via a groove and a nose or a projection and a recess engage with each other. Particularly preferably, the angle guide plate comprises a frame portion, which preferably has a height between 0.5 and 12 mm. In this case, the frame area can extend continuously along the rail longitudinal direction or is configured interrupted in the rail longitudinal direction. Furthermore, it is conceivable that the threshold has on its upper side an area with a structure for frictional engagement with the intermediate layer or the further intermediate layer.

It is also conceivable that the depression and / or elevation is formed in the angled guide plate, wherein the intermediate layer and / or the further intermediate layer is arranged on the angled guide plate.

Conveniently, the recess, the survey and / or the angled guide plate on a contact surface, which rests in the assembled state of the intermediate layer or the further intermediate layer on, wherein the contact surface for additional fixation of the intermediate layer and / or further intermediate layer is structured. As a result, an additional fixation with respect to an offset in the longitudinal direction and / or transverse direction can advantageously be provided. For example, the structuring is designed as a groove system or roughening at the top of the threshold.

In particular, in the assembled state, the intermediate layer and the further intermediate layer run essentially parallel to one another in the rail longitudinal direction.

Conveniently, the intermediate layer arranged in the recess and / or further intermediate layer projects with respect to the upper side of the threshold. In particular, the intermediate layer comprises a retractable portion, which is arranged in the mounted state in the recess, and a projecting portion which projects from the top of the threshold. As a result, it can be advantageously ensured that the rail does not rest on the threshold. It is preferably provided that the projecting portion and the recessed portion are substantially the same thickness.

The intermediate layer preferably differs from the further intermediate layer, in particular with regard to its shape and / or material composition. This can be taken advantage of the fact that the outer liner is less heavily loaded compared to the inner further intermediate layer. For example, a distinction with regard to the shape can be realized by different expansions along the transverse direction of the rail. It is also conceivable that the further intermediate layer has more recesses than the intermediate layer. This can be saved with advantage material in the further intermediate layer. Another advantage of a material-free area under the rail is the introduction of mounting aids such as sliding wedges or plates. This facilitates the installation of the rail, especially in the so-called "rail pulling".

Furthermore, it is particularly preferred if the width of the intermediate layer dimensioned in the transverse direction of the track differs from the width of the further intermediate layer dimensioned in the transverse direction of the rail. This also makes it possible to take into account the different loads when tilting the intermediate layer. It is also conceivable that groove-shaped savings are provided at the top and / or bottom of the intermediate layer or the further intermediate layer and the number of groove-shaped savings influences the shape and thereby the elastic restoring force of the intermediate layer or the intermediate alga. Furthermore, it is conceivable that the liner thicker or thinner than the other intermediate layer. A thickness difference between the intermediate layer and the further intermediate layer can be realized, for example, by the respective arrangement at the threshold in accordance with differently dimensioned savings or recesses. It is also conceivable that the intermediate layer and the further intermediate layer differ from each other in terms of their thickness before installation and have the same thickness in the installed state due to their different elastic properties under the load of the rail.

Particularly preferably, it is provided that the intermediate layer or the further intermediate layer are designed to be homogeneous in the transverse direction of the rail. Ie. When viewed in the transverse direction of the rail, neither the intermediate layer nor the further intermediate layer changes, whereby at the same time a difference between the intermediate layer and the further intermediate layer in terms of material and shape is preferably given at the same time.

Alternatively, it is also conceivable that the intermediate layer and / or the further intermediate layer in the transverse direction of the rail changes with regard to material and / or shaping. For example, a density of the intermediate layer or the further intermediate layer changes in a direction parallel to the transverse direction of the rail. It is also conceivable that the intermediate layer and the further intermediate layer converge in a wedge shape or taper, in particular in the direction of the central region of the rail foot.

Furthermore, it is particularly preferred if the intermediate layer and / or the further intermediate layer solid, d. H. free of recesses, are designed. Such intermediate layers can be produced comparatively easily and with controlled, homogeneous properties.

• ein Kantenschutzelement und/oder
• eine funktionale Beschichtung auf einer der Schiene zugewandten Seite auf. Beispielsweise ist der vorstehende Abschnitt der Zwischenlage in Schienenquerrichtung breiter als die in derselben Richtung bemessene Breite der Vertiefung. Dadurch steht der vorstehende Abschnitt der Zwischenlage bzw. der weiteren Zwischenlage in Schienenquerrichtung vor und bedeckt die Vertiefung. Dadurch wird mit Vorteil eine Spaltbildung zwischen Zwischenlage und Vertiefung vermieden, wenn unter Belastung der Schiene in Schienenquerrichtung an der Oberseite der Zwischenlage wirkende Scherkräfte wirken, und die Vertiefung bleibt durch die Zwischenlage bedeckt. Als funktionale Beschichtung ist beispielsweise eine Verschleiß- und/oder Gleitmodifizierung der im montierten Zustand der Schiene zugewandten Seite/Oberseite denkbar. Insbesondere ist die der Schiene zugewandte Seite derart beschichtet, dass ihre Gleitfähigkeit (gegenüber einem nicht-beschichteten Zustand) erhöht wird. Dadurch werden auf die Zwischenlage wirkende Scherkräfte bei der Zugüberfahrt reduziert. Ferner ist es vorstellbar, dass die Zwischenlage mit einer funktionalen Beschichtung ausgestattet ist, die mit den zu erwartenden Witterungsverhältnissen abgestimmt ist, um mit Vorteil die Lebensdauer der Zwischenlage zu erhöhen.

In particular, the intermediate layer and / or further intermediate layer

• an edge protection element and / or
• a functional coating on a side facing the rail on. For example, the projecting portion of the intermediate layer in the transverse direction of the rail is wider than the width of the recess measured in the same direction. As a result, the projecting portion of the intermediate layer or the further intermediate layer projects in the transverse direction of the track and covers the depression. As a result, a gap formation between the intermediate layer and the recess is advantageously avoided when acting under load of the rail in the transverse direction of the rail at the top of the intermediate layer acting shear forces, and the recess remains covered by the intermediate layer. As a functional coating, for example, a wear and / or sliding modification of the side facing in the mounted state of the rail / top conceivable. In particular, the rail facing side is coated so that its lubricity (compared to a non-coated state) is increased. As a result, shearing forces acting on the intermediate layer are reduced during the train crossing. Furthermore, it is conceivable that the intermediate layer is equipped with a functional coating, which is tuned with the expected weather conditions in order to increase advantageously the life of the intermediate layer.

Preferably, the functional coating extends in the rail longitudinal direction strip-shaped, so that advantageously the "rail pulling" is supported, but a slipping in the transverse direction is made difficult by lying between the strip-shaped areas, which are free of a coating.

Conveniently, the properties of the intermediate layer and / or the further intermediate layer in the rail longitudinal direction and / or rail transverse direction are modulated. Under a modulation, a variation in terms of material properties and / or shape is conceivable. In addition to a strip-shaped form of the intermediate layer, for example, a wave-shaped configuration or a configuration with a stepped edge course is also conceivable. In addition, it is conceivable that the intermediate layer is formed of several materials. For example, the intermediate layers are designed multi-layered.

Another aspect of the present invention is an arrangement of a system for holding a rail comprising a sill and an intermediate layer disposed in an assembled state between the sill and the rail and whose width in the rail transverse direction is smaller than a width measured in the rail transverse direction Rail, wherein in the assembled state, the intermediate layer is disposed below an edge region of the rail and an area under a central region of the rail - preferably over the entire extension of the intermediate layer in the rail longitudinal direction - freely, d. H. free of material, remains. All features described for the system according to the invention and their advantages can be analogously also transferred to the inventive arrangement and vice versa. It is advantageous to dispense with material in the region below the central region of the rail, in particular over the entire extent of the threshold in the rail longitudinal direction.

Another object of the present invention is a method for producing a system with a threshold and an intermediate layer, which is arranged in an assembled state between the threshold and the rail and whose extension in the transverse direction of the rail is smaller than a width measured in the rail transverse direction of the rail Providing the intermediate layer, preferably as a molded part, by pressing, injection molding and / or extrusion, and arranging the intermediate layer under an edge region of the rail. All features described for the system according to the invention and the corresponding arrangement and their advantages can be analogously also transferred to the inventive method and vice versa.

Another object of the present invention is a threshold for supporting a rail, wherein the threshold has means for fixing the intermediate layer against displacement in rail transverse direction, wherein the extension of the intermediate layer in the rail transverse direction is smaller than a width measured in the rail transverse direction of the rail. All for the system according to the invention as well as for the corresponding arrangement and the method described features and their advantages can be analogously also transferred to the inventive method and vice versa.

In FIG. 1 a system 1 for holding a rail 2 is shown. In this case, the system 1 is shown together with the rail 2 in a section along the transverse direction of the rail QR. Such a system 1 is preferably intended to connect the rail 2 to a threshold 3 in a functional manner. Essential components of the system 1 are the threshold 3 and an intermediate layer 4, which is arranged in the assembled state between the rail 2 and the threshold 3. In this case, the rail 2 extends along a rail longitudinal direction over a plurality of sleepers 3 and a further rail is viewed in the rail transverse direction QR offset from the rail 2 arranged. Between the rail 2 and the other rail thus forms a gap.

By means of the intermediate layer 4, it is possible in an advantageous manner to transmit the forces F, which act on the rail 2 when crossing a train, as uniformly as possible to the threshold 3. The intermediate layers 4 are designed such that they provide for a corresponding provision of the rail 2 after crossing. Like in the FIG. 1 can be seen, the rail 2 in the crossing about a parallel to the rail longitudinal direction extending pivot axis S by an angle outwards, ie towards a direction away from the gap ZR between the rail 2 and the other rail in the rail transverse direction QR direction, twisted or tilted , As a result of this tilting or rotational movement, the intermediate layer 4 below the edge region, in particular the outer edge region, claimed more than the region of the intermediate layer, which seen below the transverse edge region RB in the transverse direction RB opposite edge region RB ', d. h, an inner edge area.

In the FIG. 2 Figure 1 schematically shows a system 1 according to a first preferred embodiment of the present invention. In order to save material, an intermediate layer 4 is provided whose extension A in the transverse direction of the rail QR is smaller than a width B of the rail 2 dimensioned in the transverse direction of the rail QR, the intermediate layer 4 being under an edge region in the mounted state RB of the rail 2 is arranged. In particular, the intermediate layer 4 is arranged below the outer edge region RB of the rail 2. Preferably, a further intermediate layer 4 'is arranged below an inner further edge region RB' and / or runs parallel to the intermediate layer 4. An edge region RB is preferably a region which adjoins a closing surface AK of the rail 2, as seen in the transverse direction of the web QR, whose length L corresponds to a 0.4 times, preferably a 0.35 and particularly preferably a 0.3 times the width B of the rail 2 in the transverse direction of the rail. In this case, the intermediate layer 4 can be flush with the end surface AK and / or is offset in the direction of a central region Z below the rail 2 with respect to the end surface AK. Furthermore, it is provided that a ratio between an extension A of the intermediate layer 4 and / or the further intermediate layer 4 'to the width B of the rail 2 is between 0.03 and 0.4, preferably between 0.06 and 0.35 and more preferably between 0.10 and 0.3. It has been found to be advantageous that such a narrow-dimensioned intermediate layer 4 or further intermediate layer 4 'is sufficient to ensure a sufficient distribution of force during a crossing and return of the rail 2. Advantageously, a central region Z can then remain free of material without having to forego the positive properties of an intermediate layer 4.

Preferably, the intermediate layer 4 and the further intermediate layer 4 'are identical or differ with respect to their material composition and shape. With a different material composition and / or shape can be taken advantage of the fact that the intermediate layer 4 under the outer edge region RB is more stressed than the further intermediate layer 4 'below the inner further edge region RB'. Accordingly, the intermediate layer 4 and the further intermediate layer 4 'can be designed. For example, it is also conceivable that an extension A of the further intermediate layer 4 'measured in the transverse direction of the rail QR is smaller than an extension of the intermediate layer 4 measured in the transverse direction of the rail QR. Furthermore, it is preferably provided that that the intermediate layer 4 and the further intermediate layer 4 'are adapted to their expected loads, for example, the intermediate layer 4 for rail fastening differs in an arc range from that which is provided for a straight rail 2.

Furthermore, angled guide plates 5 are provided for fastening the rail 2 and in particular for fixing them, which adjoin the rail 2 in the assembled state in the rail transverse direction QR on the outside and on the inside. The angle guide plates 5 by means of a connecting means 7, for example a bolt and / or screw, mounted on the threshold 3 and fix it via a spring element 6, the rail 2 at the threshold 3. For this purpose, the spring element 6 overlaps the edge region RB of the rail 2 and clamped this with the threshold 3. On a side facing the threshold 3, the angle guide plate 5 also has a contour course, which corresponds to a complementary course in the threshold. As a result, the angle guide plate 5 can be aligned specifically during assembly and embedded in the threshold 3.

In the in FIG. 2 illustrated embodiment, it is provided that the threshold 3 has a recess 9 for receiving the intermediate layer 4 and the further intermediate layer 4 '. As a result, the intermediate layer 4 can advantageously be secured or fixed with respect to an offset in the transverse direction of the rail QR. In addition, the recess 9 supports the orientation and arrangement of the intermediate layer 4 during assembly. In this case, the intermediate layer 4 and / or the further intermediate layer 4 'are dimensioned such that the embedded in the recess 9 intermediate layer 4 and / or further intermediate layer 4' protrudes from a top OS of the threshold 3. In particular, it is provided that the intermediate layer 4 and / or the further intermediate layer 4 'have a retractable portion 42 and a projecting portion 41. In this case, the projecting portion 41 protrudes in the mounted state against the upper side OS and the retractable portion 42 is sunk in the recess 9. Preferably, the projecting portion 41 seen in the transverse direction of the rail QR wider than the retractable portion 42 so that the protruding portion can cover the recess 9 like a cover to form an edge protector. Preferably, it is provided that the retractable portion 42 and the protruding portion 41 are made of different materials, thus taking into account that the protruding portion 41 is subjected to higher loads than the retractable portion 42. Further, it is preferable that a depth T1 of the recess 9 is smaller than a maximum depth T2 of the contour 8 on the upper side OS of the threshold 3, which is provided for the angled guide plate 5. For example, a ratio between the depth T1 of the depression to a maximum depth T2 of the contour 8 assumes a value between 0.2 and 0.7, preferably between 0.3 and 0.6 and particularly preferably between 0.4 and 0.5 ,

In FIG. 3 the threshold 3 for the system 1 according to the first preferred embodiment of the present invention is shown, in particular without angle guide plate 5, spring element 6, intermediate layer 4, rail 2 and connecting element 7. For simplicity, only a rectangular cross section is shown. There are also trapezoidal, curved, circular recesses as wells 9 conceivable. Corresponding to the shape of the recess 9 then tailored spacers 4 are inserted into the recess 9. For example, one or more circular or elliptical recesses 9 are conceivable, in which round or elliptical intermediate layers 4 can be used, as in FIG. 7 For example, circular or elliptical intermediate layers 4 with a circle diameter between 20 and 70 mm for a UIC 60 rail would be conceivable. For example, the depressions 9, preferably two depressions, are arranged below the edge region RB or the further edge region RB and are particularly preferably arranged in a direction perpendicular to the transverse direction of the bar QR, one behind the other or offset from one another. Furthermore, it is conceivable that the recesses 9 on the side for the edge region and the recesses 9 on the side for the other Randberiech are symmetrical to each other, in particular with respect to a through the pivot axis S and perpendicular to the transverse direction of the rail QR mirror plane.

In FIG. 4 a threshold 3 according to a second preferred embodiment of the present invention is shown. This is different in the FIG. 4 represented by the one from the FIG. 3 to the effect that for aligning or fixing the intermediate layer 4 instead of a recess 9 in each case a survey 11 is provided. Thus, below the inner further edge region Rb 'and the outer edge region RB there is a respective elevation 11 on which the intermediate layer 4 and the further intermediate layer 4' can be positioned. It is also conceivable that for fixing the intermediate layer 4 ribs or webs 21 protrude from the threshold 3, as it is in FIG. 8 is indicated schematically. These ribs enclose in the assembled state, the intermediate layer 4 circumferentially. In FIG. 5 a threshold 3 according to a third preferred embodiment of the present invention is shown. This is different in the FIG. 5 illustrated embodiment of that of the FIG. 4 to the effect that instead of two parallel aligned elevations 11 a survey 11 is provided in the central region Z. Seen in the transverse direction of the rail QR borders on the elevation 11 in the central region Z then against the elevation 11 set back sections, which serve as a recess - as known from the embodiment of Figure 3 - for aligning the liner 4 and the further intermediate layer 4 '.

In FIG. 6 a threshold 3 according to a fourth preferred embodiment of the present invention is shown. This is different in the FIG. 5 illustrated embodiment of those of the preceding figures to the effect that here the intermediate layer 4 and / or further intermediate layer 4 'is aligned or fixed by means of the angle guide plate 5 at the threshold 3. For this purpose, it is conceivable, for example, that the intermediate layer 4 and / or further intermediate layer 4 'has a partial section which is thinner than a section adjoining in the mounted state, which under the edge region RB or the other Edge region RB 'of the rail 2 is arranged. The thin portion can then be arranged, for example, below the angle guide plate 5 and is clamped between the angle guide plate 5 and the threshold 2 accordingly.

Preferably, it is provided that the recess 9, the elevation 10 and / or the angled guide plate 5 have a contact surface which rests in the mounted state on the intermediate layer 4 or the further intermediate layer 4 ', wherein the contact surface for additional fixation of the intermediate layer and / or further intermediate layer is structured. For example, the recess 4, the survey and / or the angled guide plate groove or knob-like structures with which the intermediate layer and / or the further intermediate layer is possible slidably positioned at the threshold. It is also conceivable that a structuring on the upper side of the threshold 2 is provided as a means for fixing the intermediate layer 4 or the further intermediate layer 4 '.
