Description

System for securing a rail and

Fixing a rail

The invention relates to a system for securing a rail to a ground and a fastening of a rail using such a system.

When mounting rails that are used at lower loads and speeds, as is the case for trams, on the one hand, the lowest possible wear and tear

On the other hand, the driving comfort and the minimization of noise emissions in the foreground. At the same time such fasteners should be easy to install and inexpensive to produce.

In rail fasteners used in practice, these requirements are met in that the rails on a fixed, such as a

Concrete threshold or made of concrete

Single support point formed substrate are mounted, with an elastic layer is arranged with defined compliance between the rail and the solid ground. The resilience of the elastic

Layer is chosen so that the rail when driving over in the region of the respective attachment the same Behavior shows, as in the freely spanned, unsupported area between two fortifications.

The rail fastening is in such fortifications the task of securing the position of the rail in the horizontal transverse direction to its longitudinal extent and to prevent lifting of the rail in the vertical direction of the elastic layer.

In one known from DE 198 48 928 AI

Rail fastening system is the rail a the rail foot laterally overlapping, substantially C-shaped elastic bearing profile, which lies on a threshold consisting of concrete. By this arrangement, a quiet, damped running of the tram should be guaranteed on the rail. For holding down the rail clamping profiles are used, which are screwed by means of one in each case in the threshold

Fixing screw to be fixed. The clamping profiles have a supported on the threshold

Attachment section on which a projection is formed, which presses in the assembled state on the free upper side of the rail foot. At the same time a

To allow gauging, are in the

known system additionally trapezoidal, lateral track edges of the rail support the threshold

slidable track profiles provided for

Rail longitudinal direction parallel slots for the

Have fastening screws. The track profiles form in this way one in the horizontal direction

adjustable transverse guide of each associated

Rail. A problem that has proven in the practical use of rail fasteners of the type described above, that loosen the mounting screws, so that the attachment has to be maintained after a comparatively short period of use.

Against this background, the problem to be solved by the invention was to provide a system for the attachment of a rail, which is not only easy to install, but at the same time over a prolonged period of use, a secure hold of the rail

guaranteed. In addition, an appropriately designed attachment for a rail should be created.

According to the invention, this object with respect to the system by a designed according to claim 1 system for

Rail fastening has been solved. advantageous

Embodiments of the system according to the invention are specified in the dependent claims on claim 1.

In terms of attachment is the above

said object has been achieved according to the invention in that this attachment according to claim 15

is trained. Advantageous embodiments of a fastening according to the invention are specified in the claims back to claim 15.

An inventive system for securing a rail on a substrate, in particular by a threshold of concrete or a comparatively solid material or a corresponding single base may be formed comprises a guide plate, a fastener and a spring element.

The guide plate serves as a guide of the one hand

Rail in horizontal direction. On the other hand, it forms in combination with the spring element in the assembled position a stop for movements of the rail in the vertical direction.

The guide plate has a bearing surface, with which it is supported in the mounting position on the ground. In this case, the guide plate can either rest directly on the ground or it can, if this proves to be necessary, between the ground and the guide plate, a further layer be present, for example, an elastic support or protection against wear.

For the lateral, horizontal guidance of the rail, the guide plate also has a contact surface, at the mounting position of the rail with his

Long side abuts.

Finally, in the guide plate of a

System according to the invention also one of their

Top leading to its support surface

Molded through opening for a clamping element which is inserted through the passage opening of the guide plate to be fixed in the ground.

The clamping element is used to tension one from a

Spring wire bent spring element, which in Mounting position applies an elastic hold-down force on the guide plate. At the same time that works

Spring element in the manner of a stop, by which the vertical movements are limited, which performs the rail when driving over a rail vehicle.

To fulfill this dual function, this indicates

Spring element at least one torsion portion, at one end thereof opposite the torsion portion angled aligned first support portion and at the other end one of the Torsionsabschnitt

bent further support portion is formed. The length and the angular position of the first support portion with respect to the torsion portion are dimensioned such that in the assembled position of the first

Support portion of the spring element on an associated support surface at the top of the guide plate

supported and the spring element is clamped by means of the clamping element against the ground so that the

Torsionsabschnitt exerts an elastic restoring force. Accordingly, with the spring element relaxed, the first support section at an angle in the radial direction is at an angle away from the torsion section in such a way that it exerts a torque on the torsion section in the tensioned state, by which the torsion section is twisted. At the same time, the length of the torsion portion of the spring element is dimensioned such that the torsion portion in the assembly position with its the further support portion associated end over the contact surface of the

Guide plate is in the direction of the rail out. In this way, the Torsionsabschnitt has a sufficient length to the mounting state

required elasticity with which the guide plate is held down to ensure. The second connected to the Torsionsabschnitt support portion is shaped so that it is also supported in the mounting position on the guide plate and forms an abutment for the torsion of Torsionsabschnitts.

At the same time it forms over the contact surface of the

Guide plate protruding section of the

Torsion section as a support a stop for the vertical movements of the rail.

As a result of the shaping according to the invention of the guide plate and the spring element, a direction directed in a vertical direction perpendicular to the respective substrate is thus produced

achieves elastically yielding support of the rail foot, in which the hold down forces exerted on the rail foot are determined solely by the force with which presses the further support section projecting beyond the rail foot on the rail. In this way, it is readily possible in a system according to the invention, the shape of the guide plate and the arrangement of the spring element to each other

to agree that in the unloaded mounting condition

at most minimal, in particular no hold down forces are exerted on the rail.

The latter proves to be particularly useful if between the rail and the solid ground, an elastic intermediate layer is installed, the one Ensures defined compliance of the rail when driving over the respective attachment. For this purpose, in a fastening according to the invention or a system according to the invention, the distance between the base of the rail to be fastened rail associated underside of the projection of the AufStandfläche the guide plate be substantially equal to the distance of the free surface of the rail foot to the surface of the solid ground.

To the electrical insulation of the usually made of a conductive spring steel spring element

To ensure against the rail to be fastened, an existing of a non-conductive material insulator element may be provided, which mounted in a system according to the invention finished

Attachment point between the rail and the foot over the rail protruding portion of the spring element is arranged. In order to facilitate the mounting of this insulating element, the insulating element may be provided with at least one latching device, via which it can be latched to the region of the spring element assigned to it.

The low hold-down forces according to the invention, which are exerted by the spring element in the assembled state with unloaded rail on the rail, can be precisely dosed in a particularly simple manner that at least one projecting beyond the contact surface in the direction of the associated rail protrusion is formed on the guide plate. This is then shaped and arranged so that it protrudes in mounting position on the free top of the rail foot, especially with little or no

Hold-down force rests on her, and as such forms the stop for the vertical movements of the rail. In case the guide plate is made of a non-conductive material, the projection serves

at the same time as an insulator, which isolates the spring element against the rail foot. In case of excessive vertical movement of the rail damage to the guide plate

keep away, may be provided in the region of the transition from the projection to the guide plate a predetermined breaking point. After breakage of the predetermined breaking point of the projection continues to serve as an insulator and still ensures that the applied by the spring element

Hold-down forces over a large area on the rail foot

be distributed.

In a system according to the invention the limited with the other support portion in the assembled state over the

Rail foot standing area of the spring element thus resiliently vertical movements that performs the rail during operation, without causing in the unloaded state of the rail large hold-down forces on the

Rail are exercised. The rail owns

Accordingly, in the vertical direction, a comparably large free travel and yet it is on the other hand secured that their induced under load by a rail vehicle movements are too large.

In the case that the solid ground is formed by sleepers or individual support points, the elastic layer is preferably designed so that the rail during the

Passing through a rail vehicle in the area of Help formed a system according to the invention

Attachment at least approximately as drops as in the areas between two thresholds in which it is not supported.

In the case that the guide plate is provided with the above-explained, the spring element supporting projection and the projection and with him the

Guide plate is loaded as a result of a vertically directed movement of the rail, this load is cushioned by the spring element with the result that stress impacts of the clamping element

be kept away. In this way, the risk that the stress caused by the clamping element of the guide plate prematurely loosens on the solid ground, reduced to a minimum.

With the invention, therefore, a fastening system is available, which with a very small number of

Components a permanently secure guidance of a

especially for tram traffic or

comparable applications specific rails

guaranteed. The small number of parts makes that

Not only is the system according to the invention particularly easy to assemble, but it also makes it possible to produce such a system in a particularly cost-effective manner.

The over the contact surface protruding portion of the torsion portion of the spring element can as

Support for the stopper made by the optional projection of the guide plate can then be used particularly effectively when in Assembly position at least the further support portion or the torsion on the projection of

Guide plate rest and the projection on its free, from the AufStandfläche the guide plate

Having turned away upper side at least one guide for the further support portion or the torsion portion.

By the guide plate on its side opposite the contact surface side has a support surface, which in the longitudinal direction imaginary extension of the

Bearing surface at an acute angle intersects, and on the solid ground, a shoulder is formed on the mounting position in the guide plate with their

Support surface is supported, can also at a

inventive system in a simple way a

Gauge setting to be made. This is especially easy to do when the

is formed, whose longitudinal axis is aligned axially parallel to the longitudinal axis of the support surface. The position of the guide plate in the respective desired track corresponding position can thereby be additionally secured that in the top of the

Guide plate locking surfaces are formed so that in the assembly position, the spring element is supported in response to the respective position of the guide plate with respect to the clamping element in one of the locking surfaces.

The guide plate is preferably made of an electrically insulating material, such as a plastic. This not only allows a special inexpensive and simple production, but

also allows for a total of isolated mounting of the rail compared to the solid ground.

As a clamping element, a screw can be used, the screw head in the mounted position on the

Torsionsabschnitt the spring element acts. Similarly, of course, a bolt on the

Bracing the spring element, a nut is screwed, or another for generating sufficiently high

Clamping forces suitable clamping element in one

inventive system can be used.

A particularly easy to assemble and at the same time functional embodiment of the invention is characterized in that the longitudinal axis of the other

Supporting portion of the spring element in the same plane as the longitudinal axis of the Torsionsabschnitts.

A particularly in view of the resilient limit of the vertical movements of the rail

Practical design of the spring element is obtained when the spring element arranged at a distance from the first torsion second

Torsion portion, the second torsion portion as the first torsion at one end in an opposite the second torsion angled aligned, in the mounting position causing a torsion of the associated torsion

Support section passes and the second torsion section with its other end to that of the first Torsion section facing away from the other

Support section is connected.

In this case, the spring element has a shape in which the torsion sections and the support sections formed thereon are arranged mirror-symmetrically. A refinement which is further optimized with regard to practical use is characterized in that the torsion sections extend parallel to one another.

As long as it is ensured that they are in the assembled state a sufficient torsional moment on the respective

However, support sections results when they are bent over an angular range of more than 90 °. In this case, the spring element provided according to the invention has a shape approximating that of a classical S- or W-shaped tension clamp, in which the length of the spring arms facing the assigned rail is reduced to such an extent that the rail foot is not touched by them.

If the rail is supported by an elastic layer on the solid ground, it may be advantageous to minimize the noise emissions, if the

For attachment in the manner of a grooved rail

trained rail S on one by one

Concrete sleeper B formed solid ground is made by two identically formed systems S1, S2, each comprising a guide plate 1, a spring element 2 and a tensioning element 3 as a clamping element. In the concrete sleeper B a flat AufStandfläche 4 is formed, which collides at its longitudinal edges with the longitudinal sides of the threshold B and is limited at its narrow sides by a respective shoulder 5,6. The contact surfaces 4, mutually parallel bearing surfaces 7,8 of the shoulders 5,6 each meet at an acute angle to the longitudinal edges of the support surface 4, so that the support surface 4 in plan view has the shape of a parallelogram.

Those from a non-conductive, for example

Fiber-reinforced plastic produced guide plate 1 has on its underside in each case a support surface 9, with which it lies in the mounting state on the support surface 4 of the threshold B. At its rail foot F of the rail S associated side abuts the support surface 9 on a contact surface 10 which is aligned approximately at right angles to the support surface 9. With the exception of their adjacent to the top 11 of the guide plate 1 corner regions and also adjacent to the upper side 11 central region extends

Surface 10 thereby over the entire height of

Guide plate 1. In the respective corner areas in each case one in the direction of the web E of the rail S pointing projection 12,13 is integrally formed on the guide plate 1. The projections 12,13 serve as

additional protection against tilting of the rail S or the guide plate. 1

In the middle between the projections 12,13 arranged central region of the contact surface 10 is a U-shaped projection 14 to the guide plate 1 in one piece molded, which also points in the direction of the web E of the rail S. The projecting beyond the contact surface 10 length of the projection 14 is significantly greater than the corresponding length of the type of

Stops shaped projections 12,13. In the area of the transition from the projection 14 to the main body of

Guide plate 1 is a along the contact surface 10 extending predetermined breaking point 27 is formed, at the corresponding load the projection 14 of the

Guide plate 1 breaks off.

The distance Av of the underside of the projections 12,13,14 from the support surface 9 of the guide plate 1 is at least as large as the respective distance Af of

In this way, a very low hold-down force on the rail foot F is exerted on the projection 14 and a guided therein middle loop of the spring element 2 respectively at best mounted system Sl, S2.

In the top of the central projection 14 is a throat-shaped, the U-shape of the projection 14 following guideway 16 is formed.

In the area of the transition of the projection 14 in the

Main body of the guide plate 1 are additional

Throat-shaped locking surfaces 17 formed in the top 11 of the guide plate 1, the orientation of the

Alignment of the projections 12-14 corresponds. In addition, a trained as a slot

Through opening 18 formed in the guide plate 1, which from the top 11 to the support surface 9 of

Guide plate 1 leads. The longitudinal axis L18 of

Through opening 18 is aligned so that it intersects the contact surface 10 at an acute angle.

Furthermore, in the top 11 of the guide plate 1 is over the length L of the guide plate. 1

extending strip-shaped support surface 19 sunk.

At the opposite side of the contact surface 10 of the guide plate is finally another

Support surface 20 is formed, which is parallel to the longitudinal axis L18 of the through hole 18 and substantially

is aligned perpendicular to the support surface 9 of the guide plate 1. About the support surface 20 is the

Guide plate 1 at the respectively associated contact surface 7 and 8 of the shoulders 5 and 6 of the concrete sleeper 5 supported. By moving the respective

Guide plate 1 along the associated contact surface 7.8 can be while the position of the rail in the width direction BR for the purpose of setting the track width of the track

adjust to which the rail S belongs. The travel of this adjustment is determined by the length of the

Through opening 18 limited.

The clamping screw 3 of the systems S1, S2 are each a conventional sleeper screw. For their attachment, an opening 21 is provided in the threshold B, in which a not here

represented plastic anchor sits. The spring element 2 has a mirror-symmetrical shape approximating to W and comprises two mutually parallel torsion sections 22, 23 which are connected at their one end to a support section 24, 25 and at their other end via a further support section 26. The former

Support sections 24, 25 are each opposite the associated torsion section 22, 23 downwards

angled bent from the respective torsion portion 22,23 and each encompass circular arc an angular range of about 180 °. Likewise, the torsion sections 22,23 interconnecting

Support section 26 formed semicircular. However, its longitudinal axis L26 extends in the same plane as the longitudinal axes L22, L23 of the torsion sections 22, 23, whereas the longitudinal axes L24 and L25 of the support sections 24, 25 pierce the plane spanned by the longitudinal axes L22, L23 at an acute angle. Together with the torsion sections 22, 23, the support section 26 forms the middle loop of the spring element 2.

The rail foot F and the web E of the rail are complete with a layer G of an elastic

Material covered. This ensures at the ready mounted attachment of the rail S on the one hand a defined compliance and on the other hand a

Minimized noise emission when driving over the rail S.

To mount the attachment, the rail S is placed with its rail F with the elastic layer G-clad rail foot on the AufStandfläche 4 of the threshold B. Subsequently, the guide plates 1 of Systems S1, S2 positioned so that, with proper compliance with the prescribed track width, the rail S is guided laterally substantially free of play between the shoulders 5.6 of the threshold B. The rail foot F rests with its longitudinal sides against the contact surface 10 of the guide plates 1. Subsequently, the

Spring elements 2 set on the guide plates 1, that their free support portions 24,25 on the

Support surface 19 of the guide plate 1 sit. In this case, the length of the torsion sections 22, 23 of the spring element 1 is selected such that the torsion sections 22, 23 and the support section 26 connecting them to one another via the

Bearing surface 10 standing out in the molded into the projection 14 guideway 16 are guided.

Subsequently, the respective clamping screw 3 is screwed into its respective associated opening 21 of the threshold S, to over the screw head of the

Clamping screw 3 the respective spring element 2 is pressed so far against its associated guide plate 1, that acts on the associated with the depression twisting the Torsionsabschnitte 22,23 a sufficient elastic hold-down force on the guide plates 1. The rail S moves when crossing over by

Rail vehicle in the vertical direction perpendicular to AufStandfläche 4 and abuts against one of

Tabs 12-14, so will this push through the

Spring elements 2 received elastically. The respective clamping screw 3 of the systems S1, S2 is thus protected against excessive impact, so that the risk of premature loosening of the attachment is safely prevented. If there is a high load of the spring element 2 during assembly or during ongoing practical use, the projection 14 breaks off at the predetermined breaking point, so that the middle loop of the spring element 2 on the

Rail foot F is supported. The breaking point

thus ensures that even with a beyond the projection 14 own elasticity stress, for example, as a result of a particularly large movement of the rail foot in the vertical direction, this burden is kept away from the attachment of the guide plate 1 and resiliently intercepted.

In Fig. 7, which shows an alternative embodiment of a rail fastening according to the invention, the same reference numerals have been assigned to those used in this attachment components that have been used in the attachment described above, as in Figures 1 to 6.

In the mounting of the rail S shown in Fig. 7, as in the attachment shown in Fig. 1, two systems S3, S4 have been used, one of which is arranged on one side and the other on the other side of the rail S. , The system S3 shown on the left side of Fig. 7 is in the fully assembled position while the right side system S4 is shown in the pre-assembly position.

The systems S3, S4 each comprise a spring element 2, a clamping element 3 designed as a clamping screw, a guide plate 30 and an insulator element 31

Difference to those provided in the systems S1, S2 Guide plate 1 is formed on the guide plate 30 is not formed with the projections 12,13 or 14 comparable molding element, so that the guide plates 30 are limited by their contact surface 10 in the direction of the rail S. In the systems S3, S4 is thus the other

Support portion 26 and the support portion associated with the end portions of the torsion portions 22,23 of the respective spring element 2 is not on a in the original state firmly connected to the respective guide plate projection, but are free on the respective

Guide plate 30 in the direction of the rail S before. However, since the torsion sections 22, 23 continue to be supported on the guide plate 30 over most of their length, only minimized hold-down forces are also minimized in the systems S3, S4 in the fully assembled state by the respective spring element 2 when the rail S is unloaded on the with the

elastic layer G covered rail foot F exerted.

The insulator element 31 made of a non-conductive material is positioned between the rail foot F and the further support section 26 arranged above it and by means of a latching connection 32

Captive, but releasably coupled to the support portion 26. On its side facing the rail foot F, the insulator element 31 has a plane

Support surface on which applied by the spring element 2, small forces evenly distributed on the elastic layer G are applied. The function of the insulator element 31 corresponds to the extent of the function provided for in the systems S1, S2 projection 14, after the projection 14 due to a break of the Predetermined breaking point 27 has been separated from the respective guide plate 1.

In order to facilitate a positionally accurate pre-assembly of the systems S3, S4 are in the of the contact surface 10th

side facing away from the guide plates 30 upwards and to the side facing away from the rail S open

Recesses 33 molded. In these recesses 33 sit, as shown in the right part of Fig. 7, in

Vormontagestellung the ends of the first support portions 24,25 of the spring elements. 2

The invention thus relates to a guide plate 1.30, a fastening element 3 and a spring element 2 comprehensive system S1, S2 for the attachment of a

Rail S on a solid surface B. The

Guide plate 1.30 serves as a guide rail S in horizontal and as a stop for movements of

Rail S in the vertical direction. For this purpose, the

Guide plate 1.30 on a contact surface 10, in the mounting position of the rail foot F abuts with its longitudinal side. To the guide plate 1.30 is optional

at least one projecting beyond the contact surface 10 in the direction of the associated rail S protruding projection 14 which lies with minimized hold-down force on the rail S and as such constitutes the stop for the vertical movements of the rail S. The resting on the guide plate 1.30 spring element 2 is designed and supported in the assembled state on the associated guide plate 1.30, that it exerts essentially no hold-down force on the rail S, but only the guide plate 1.30 elastically against the for their attachment inserted clamping element 3 is supported. The spring element 2 has to a W- or S-shaped configuration and protrudes with one of the two

Torsionsabschnitten 22,23 and the between them

lying support portion 26 middle loop portion so far over the rail foot F, that the rail foot F, when it is moved away in the vertical direction of the solid substrate B upwards, is resiliently held by the spring element 2.
