Description

Rail attachment point and shim for such a rail attachment point

The invention relates to a rail fastening point, in which a rail for a rail vehicle on a

Ground is attached. In such a

Fixing point to be fastened rails usually have a rail head, at the top of a

Tread for the rail wheel of a rail vehicle is formed, a rail head bearing

Rail web and a rail foot, which is considered in cross-section substantially wider than the rail web and the rail head and on which the rail web. With the rail foot, the rail is in the finished mounted position on the respective ground, wherein between it and the ground different layers may be present to the contact between the rail and the

To convey underground.

Thus, a plate-shaped intermediate layer can be arranged between the rail and the ground, which consists of a material with precisely defined flexibility and ensures that the rail sinks elastically yielding when driving over the attachment point by a defined amount.

Furthermore, between the rail foot and the Underground a shim be present. These

Shim plate on the one hand optimally adapted to the shape of its associated bottom of the rail foot

adapted AufStandfläche available and compensates in particular unevenness of the subsurface. On the other hand, the shim can be used to set a defined height position of the rail above the ground.

In addition to the shim and the optional existing elastic intermediate plate include

Rail attachment points of the type in question here usually two guide plates, each of which a guide plate is assigned to one of the longitudinal sides of the rail. The guide plates absorb the transverse forces which occur when passing over the rail held in the attachment point and guide them into the ground. In order to ensure a location-accurate positioning of the guide plates even under high load, have the

Guiding plates in many applications on their subsurface associated with an angular shoulder, with which they engage positively in a recess formed in the ground recess. Angular paragraph and recess are aligned parallel to the longitudinal extent of the rail, so that the guide plate aligned even at high transverse to the longitudinal extent of the rail

Shock loads safely lingered in place. Such designed guide plates are called in practice also "angled guide plates".

In addition to the lateral support of each too

fastened rail serve at attachment points of Here in question type, the guide plates as support and guide elements for each spring element that sits on the guide plates and exercise to hold down the rail elastic, directed against the ground holddown forces on the foot of the rail. For bracing the spring element may be provided in the manner of a screw or a bolt formed clamping element which is anchored in the ground and acts against the spring element.

The ground on which a rail is fastened by means of an attachment point of the type in question here is usually formed of a threshold or plate, which is formed of concrete or a similar solid material.

Rails of a rail track for rail vehicles are usually installed at a certain inclination to the track center to align their treads on the conically shaped wheel treads of the rail wheels

adapt, with which the respective rail vehicle travels the rail. In this way, the self-centering of the rail vehicle is supported on the track.

In the area of points, the rails stand up

Simplifying the construction of the switch, however, usually vertical. However, there is also the requirement to install the rails at a predetermined inclination to get the self-centering effect in the area of the points.

It has been tried with the provision of a sloping mounting surface for the rail associated effort to solve that even slants are formed on the respective substrate, then on the

corresponding inclination of the rail is effected. This approach has however as

manufacturing technically very complex

pointed out, for different curved curves and different inclinations of the rails must be made possible.

Alternatively, it has therefore been proposed to accomplish the inclination by means of the shim, the

belongs to attachment points of the type in question by default.

An example of a suitably trained

Fixing point is in DE 10 2011 003 216 AI

described. In this prior art, the attachment point comprises a receiving trough, which is formed in the ground and laterally bounded by flanks. Against the flanks, the rail is supported in the manner already described above by means of two guide plates, one of which sits between the longitudinal side and the associated edge of the receiving trough.

In addition, a shim is provided in the known attachment point for height compensation, which extends below both angled guide plates and the foot of the rail and is guided to over the receiving trough limiting edges. In order to give the rail with respect to the vertical a certain inclination, the intermediate plate may be formed asymmetrically, so one of its one longitudinal side of the rail associated side in the direction of the side, which is assigned to the other longitudinal side of the rail, have decreasing thickness.

Another rail fastening point, in which a relative to the direction of gravity inclined inclined rail is fixed, is described in DE 35 12 200 AI. In this attachment point, the ground is formed by a threshold made of steel. On the ground a cross-sectional wedge-shaped shim made of plastic is placed, on which in turn is the rail to be fastened. At the lying in the wedge ends of the shim are cross members, which have rounded, groove-like bearing surfaces. In the assembled state sitting on these bearing surfaces angled guide plates, which are additionally supported by support brackets, which are mounted laterally to and adjacent to the respectively associated narrow side of the respective Unterlegteils on the ground.

Against the background of the prior art described above, the object of the invention was an attachment point and one for such

Attachment point to provide suitable shim, with which with respect to the vertical inclined mounting of rails, especially in the range of

Soft, further simplified.

With regard to the attachment point, this object has been achieved according to the invention in that such a rail attachment point has the features specified in claim 1. Regarding the shim for a

Rail fastening point is the solution of the above object according to the invention is that such a shim is formed in the manner specified in claim 11.

Advantageous embodiments of the invention are specified in the dependent claims and are explained below as the general inventive concept in detail.

The invention is based on the idea that with minimal material costs and optimally easier

Assembling a secure attachment of relative to the vertical inclined rails aligned can accomplish this in a simple and cost-effective manner that in a mounting point according to the invention a shim is used, which extends at least on one longitudinal side not beyond the rail under the guide plate provided there, but up at most guided to the respective longitudinal edge.

A rail fastening point according to the invention, in which a rail for a rail vehicle is fastened to a substrate, accordingly comprises two

Guide plates, each of which a guide plate is assigned to one of the longitudinal sides of the rail, and a shim that is disposed between the substrate and the rail, wherein the shim at its top of the rail associated with a AufStandfläche on which the rail is supported, and at its underside assigned to the substrate has a bearing surface, via which the washer is supported on the substrate, and wherein the support surface and the support surface of the shim in a transverse to the longitudinal extent of the

Rail cut view between them include an acute angle, so that the shim is thinner at its the one longitudinal side of the rail associated edge than in their the other long side of the rail associated area. Here is the edge on which the

Washer is thinner, arranged under the rail.

According to the invention, the shim plate with its thicker area assigned to the other longitudinal edge of the rail is now laterally beyond the rail. It is also inventively formed on the upper side of the shim in the laterally beyond the associated longitudinal edge beyond the region of the shim a parallel to the longitudinal extent of the rail aligned recess in the form-fitting an angular section sits, which is formed on the underside of the guide plate associated with the shim.

The particular advantage of the invention is that the invention wedge-shaped base plate is particularly easy to install due to its small size, low weight and in particular the fact that at most a single guide plate is placed on it. This applies on the one hand for pre-assembly, on the other hand, however, also for replacement, when a worn shim is to be replaced by a new plate. At the same time, as the shim ends under the rail, it is possible to achieve maximum skew orientations of the rail without the use of bulky components elaborate concrete structures must be used.

The invention thus provides a rail fastening point which can not only be assembled in a simple manner, but can also be realized in a particularly cost-effective manner due to the material savings achieved. Expensive designs and greater manufacturing costs are avoided.

To a full-surface support of the rail too

ensure, it may be advantageous if, as already mentioned, the edge on which the shim is thinner, is arranged in the region of one of the longitudinal edges of the rail to be fastened, in particular flush with him

associated longitudinal edge of the rail is aligned.

Alternatively, its position can also be arranged so that the thin edge of the shim abuts against the guide plate, which is associated with the longitudinal edge of the rail, behind which the shim remains according to the invention, so beyond the shim according to the invention does not stand out.

According to the invention, therefore, the shim with its thin edge, although below the rail, that is, in the case that the rail has a pronounced rail, within the area covered by the rail foot surface area, while one of the longitudinal edges of the rail associated, while the thicker, the other Longitudinal edge of the rail assigned area laterally beyond the rail. On the one hand, this has the advantage that the shim is supported particularly securely with its thicker area and the risk of tilting of the rail is minimized despite their inclination.

On the other hand, the laterally over the rail standing out thicker part of the shim can be used as a support base for a guide plate, which on the

Washer put on the rail at her

assigned to protruding portion of the shim

Longitudinal edge leads.

In order to do a simple positionally correct mounting of

Guide plate and at the same time a simple alignment of the other components of the attachment point to

allow the AufStandfläche on which the rail is supported, laterally to the extended beyond the associated longitudinal edge of the rail area may be extended.

The correct positioning and support of the

Shims can be supported by the fact that at the bottom of the shim a projection

is formed, with which the shim engages positively in a molded-in recess in the recess. In this way, the shim is positively supported on the ground, so that a transverse displacement is excluded as a result of occurring when driving over the attachment point by a rail vehicle high forces. Transverse forces absorbed by the shim are discharged directly into the substrate via the positive connection. The recess advantageously has a trapezoidal cross-section geometry, which is a reliable removal of force in combination with an optimal self-locating positioning of the shim guaranteed.

In the same way, according to the invention, securing of the guide plate arranged on the thicker region of the base beyond the rail is thereby achieved

secured that at the top of the shim in the laterally beyond the associated longitudinal edge beyond the area of the shim a parallel to

Longitudinal extent of the rail aligned recess is formed in the form-fitting an angular section sits, which is integrally formed on the underside of the guide plate associated with the shim. About the so formed between the shim and the guide plate

positive connection is a relative displacement of these two components across the longitudinal extent safely avoided even under high load. The forces transmitted from the guide plate to the shim can then be dissipated directly into the substrate when the shim is positively coupled to the substrate in the manner explained above. An optimal Materialausnutzung- and distribution results in this case when the recess at the top and the projection on the underside of the shim are arranged one above the other. Again, it may be useful if the recess has a trapezoidal in cross-section geometry through which a safe power transfer in

Combination with an optimally self-finding

Positioning of the guide plate is secured to the shim. By the safe derivation of the transverse forces absorbed by the guide plate during operation, it is ensured that this is used for clamping the spring element arranged on the guide plate Clamping element remains largely free of heavy loads and so its long life is assured.

To a spring element, sitting on a on the thicker, beyond the rail standing area

Guide plate is supported, in a conventional manner by means of a clamping means, such as a screwed into the ground clamping screw or a clamping bolt to stretch, it is useful if in the laterally beyond the rail standing area of the

Shim is formed by a leading from its top to its bottom through hole, which is aligned with a correspondingly arranged through hole of the guide plate and when through the

mutually aligned Durchgangsöff the respective clamping element is guided, which engages for bracing a supported on the guide plate spring element in the ground.

To the attachment point a defined elastic

To give indulgence can also be at one

Rail attachment point according to the invention between the rail and the shim be provided an elastic intermediate layer. Alternatively, it is of course also possible to arrange a rigid intermediate plate for stiffening the rail fastening point according to the invention between the rail and the shim.

A lifting or tilting of the guide plates under unfavorable loads can be safely prevented by at least one of the guide plates on one of the rail associated end face contact surface optionally a has strip-like projection, with which it engages under the associated longitudinal edge of the rail.

In principle, it is conceivable to design the support surface and the support surface of the shim in such a way that their shape is adapted to the respective local conditions. A versatility, however, arises when at least one of the guide plates on one of the rail associated end face contact surface has a strip-like projection with which it engages in a recess, which is assigned by the associated bottom of the rail, a narrow side of the elastic plate and the Top of the shim is limited. This design also takes into account that the underside of a rail foot is usually also substantially flat and also the

optionally between rail and shim

arranged intermediate layers are usually formed plate-shaped with planar mutually associated surfaces.

As explained above, a shim for a rail attachment point formed according to any one of the preceding claims has an upper surface on which a support surface for each rail to be fastened is provided, and a lower surface on which a support surface is provided for laying on a substrate is provided.

According to the invention, the support surface and the support surface form an acute angle between them, so that the support plate is thinner on one side than on the other side. In this case, in the case in which the shim plate is intended to stand laterally beyond the associated longitudinal edge of the shim in the assembly position, an area exists exclusively on the thicker side of the shim

be connected, which is provided for supporting a can be placed on the area guide plate.

If an angle guide plate to be supported with its downwardly projecting angle section on the shim, it is advantageous if at the top of the guide plate in which to support one on him

attachable guide plate provided area one

Recess is formed, which is aligned transversely to the longitudinal extent of the shim. In this recess then engages the angle section of the guide plate, so that the guide plate is fixed in the mounting position non-positively and transversely to the rail immovable to the shim.

Following the same pattern may be at the bottom of the

Shim be formed a projection in the

Assembly position in a correspondingly shaped, aligned parallel to the rail recess of the ground engages to secure the shim against displacement transversely to the rail.

The invention thus combines the advantages that a

Rail fastening by means of guide plates and on the guide plates held clamps, with the

Possibility of a vertical orientation of the rail, without it being necessary

elaborate transformation of the respective underground forming threshold or plate needs. Especially

The invention proves to be advantageous in the case of

Fixing rails of a switch on conventional sleepers. The for the production of

Turnout sleepers made of concrete with tilting costs can be avoided by the invention, as the

Invention allows an inclined arrangement of the switch rails on conventional flat switch sleepers.

Hereinafter, the invention with reference to a

Excercise play drawing closer

explained. Each show schematically:

Fig. 1 shows a first attachment point for a rail in a section transverse to the longitudinal extent of

Rail;

Fig. 2 is a used in the attachment point of FIG. 1

Shim in plan view;

Fig. 3, the shim according to FIG. 2 in a

lateral view.

In the rail fastening point B shown in Fig. 1, a rail S is fixed, which is formed in a conventional manner, a rail head 1, at the top of a tread 2 for a not visible rail wheel of a rail vehicle, also not shown, a rail head 1 supporting rail web 3 and one

Rail foot 4, on which the rail web 3 is arranged centrally. The rail foot 4 is wider than the Rail head 1 and has on its underside a flat bearing surface 5.

The rail fastening point B comprises a base 6, which is formed in the present example by a concrete cast threshold of conventional design. On its upper side, the base 6 has a flat AufStandfläche 7, which is measured over the in the transversely to the rail S aligned longitudinal direction L of the ground length of the

Subsurface 6 extends.

In the AufStandfläche 7 two groove-shaped recesses 8.9 are formed at a distance from each other, which extend parallel to each other and parallel to the longitudinal extent of the rail S. The recesses 8,9 have an approximately trapezoidal cross-section which widens toward the support surface 7 of the substrate 6.

In addition, two plastic anchors 10,11 are in the ground in the limited by the recesses 8.9 area

admitted. The recesses 8,9 and the plastic dowels 10,11 are each arranged at the same distance symmetrically to the longitudinal axis of the rail S.

On the substrate 6 is made of a plastic, in particular of a fiber-reinforced plastic, produced Unterlegplatte 12. The shim 12 has a rail S associated top 13 on which a flat AufStandfläche 14 is formed.

On the AufStandfläche 14 is a plate-shaped

Interlayer 15, made of an elastic material with defined compliance exists. The intermediate layer 15 covers the rail foot 4 over its width B4 and

extends over the width B14 of the support surface 14 of the shim 12. The rail S is on its associated flat side of the intermediate layer 15, so that the rail S is supported on the support surface 14 of the shim 12 via the intermediate layer 15.

On its underside 16 assigned to the base 6, the shim 12 has a likewise flat bearing surface 17 with which it lies on the ground 6. In the

seen lateral view the AufStandfläche 14 is inclined to the support surface 17 aligned, so that the AufStandfläche 14 and the support surface 17 include an acute angle ß. The AufStandfläche 14 and the

Support surface 17 meet each other while one

Narrow side 18 of the shim 12, at the one

correspondingly thin edge 19 of minimized thickness Dl is formed. Accordingly, the Unterlegpatte 12 at the edge 19 associated narrow side 18 thinner than in the region of its opposite, the AufStandfläche 14 limiting narrow side 20, in the region of the thickness D2 of the shim 12 is considerably greater than the thickness Dl.

The length of the AufStandfläche 14 of the shim 12 is dimensioned so that its one narrow side 18 associated end portion is in the region of one longitudinal edge LI of the rail 4, while the opposite end of the AufStandfläche 14 at the finished mounting point B near the other longitudinal edge of the L2 Rail foot 4 is positioned. The shim 12 is over the longitudinal edge L2

associated end portion of the AufStandfläche 14, in which it has the largest thickness D2, extended beyond a region 21 to which a flat and parallel to the support surface 17 aligned AufStandfläche 22 is provided for a conventionally designed as an angle guide plate guide plate 23.

In the AufStandfläche 22 a groove-shaped recess 24 is formed, which extends parallel to the narrow side 18 and is accordingly aligned with the mounted mounting point B parallel to the rail S and transverse to the longitudinal direction of the shim 12, which has a rectangular, elongated shape in plan view. The shape of the recess 24 is adapted to a projecting in the direction of the ground 6 angle portion 25 of the guide plate 23, that when fully assembled attachment point B, the angle portion 25 is positively seated in the recess 24. At the same time, the shim 12 is bulged downward in the region of the recess 24, so that a projection 26 is formed there as well. Its outer shape is adapted to the shape of the associated, molded into the substrate 6 recess 8, that the projection 26 in the assembled mounting point B form fit in the

Recess 8 is held.

On the conventionally shaped guide plate 23, which sits on the laterally beyond the associated longitudinal edge L2 of the rail S out beyond region 21 of the shim 12, is a conventional W-shaped tension clamp

formed spring element 27 which, in a conventional manner with the free ends of its hold-down exerts an elastic hold-down force on the rail foot 4.

In the region of the edge between its resting in the mounting position on the longitudinal edge L2 of the rail foot 4 contact surface and its underside a strip-shaped projection 28 is formed on the guide plate 23 which engages with the assembled guide plate 23 under its associated longitudinal edge L2 of the rail foot 4 and thereby against the their associated edge of the liner 15 abuts. By engaging under the rail 4 projection 28 is reliably prevented that the guide plate 23 at high

Loads about a tilting axis passing through the recess 24 tilts and thereby lifts off the shim 12.

For tensioning the arranged on the guide plate 23 spring member 27 is a conventional

Threshold screw trained clamping element 29 is provided. The tensioning element 29 is through the middle loop of the

Spring element 27, one formed in the guide plate 23 and leading from the top to the bottom

Through hole 30 of the guide plate 23 and a

aligned with the passage opening 30 arranged

Through hole 31 of the shim 12 out and screwed into the associated, embedded in the ground 6 dowels 10. Over the head of the clamping element 29, the middle loop of the spring element 27 is pulled in the direction of the substrate 6 in this way and the spring element 27 is twisted as a whole that the required

Hold-down force is exerted on the rail foot 4. On the other longitudinal edge Li associated side of the rail S is also a guide plate 32 is arranged. The guide plate 32 is shaped and sized as well as the guide plate 23. In contrast to the guide plate 23, however, the guide plate 32 sits directly on the

AufStandfläche 7 of the substrate 6 and engages with its angle portion 33 in the side of this associated recess 9 of the substrate 6. The angle section 33 and the recess 9 are also together

adapted that the angle section 33 when finished

mounted mounting point B form-fitting in the

Recess 9 is held.

With its rail-shaped associated strip-shaped projection 34, the guide plate 32 engages under its associated longitudinal edge LI of the rail S and abuts one hand against the thin narrow side 18 of the

Shim 12 and on the other hand against hers

At the underside of the guide plate 32 associated side of the strip-like projection 34 has a recess whose shape and dimension are chosen so that at ready mounted mounting point B of the projection 34 via a narrow overlap region 35 on the Narrow side 18 associated end of the AufStandfläche 14 sits. In this way, a lifting or tilting of the shim 12 is also reliably prevented.

Also on the guide plate 32 designed as a conventional W-shaped tension clamp spring element 36 is arranged, which with the free ends of its hold-down an elastic hold-down force on its associated Side of the rail foot 4 exerts. For tensioning the arranged on the guide plate 32 spring element 36, a conventional sleeper screw 37 is also provided here. The sleeper screw 37 is through the middle loop of the spring element 36 and through the passage opening of the

Guided guide plate 32 and screwed into the associated, embedded in the substrate 6 dowel 11 so that the middle loop of the spring element 36 is pulled in the direction of the substrate 6 and the spring element 36 is twisted as a whole so that the required hold-down force is exerted on the rail 4.

Due to the inclined relative to the support surface 17 alignment of the support surface 14 of the shim 12, the rail S is inclined relative to the vertical V at an angle which corresponds to the between the support surface 17 and the support surface 14 of the shim 12th

enclosed acute angle ß corresponds.
