Description

The invention relates to a combination of a guide plate for laterally supporting a rail for a rail vehicle and a wedge element for adjusting the position of the rail relative to an abutment, on which the guide plate is supported in the mounting position, wherein the guide plate associated with the wedge element, in the longitudinal direction the supporting rail extending end face and a bottom, which is associated with a substrate carrying the guide plate in the assembled position, wherein the guide plate and the wedge element are coupled together via a positive connection with each other, which forms a guide for the wedge element, in which the wedge element in Longitudinal direction of the end face of the guide plate is displaceable.

Likewise, the invention relates to a system for securing a rail for a rail vehicle on a substrate, comprising a combination of a guide plate for laterally supporting the rail on an abutment formed on the ground and a wedge member for adjusting the position of the rail relative to the anvil.

With the existing in such a system wedge element, the distance of the respective guide plate to the support surface can be determined. Due to its wedge shape, the actuator can be moved from a position in which the distance between the guide plate and accordingly the rail of the respective support surface is minimal, easily in a position in which a maximum distance is present. Between these extreme positions of the actuator, further adjustment positions can be selected, each defining a different distance of the rail to the stop surface and, accordingly, another track.

An essential property of an example in the DE 101 57 676 A1 described, a wedge element for adjusting the position of the guide plate comprehensive system is that after the finished assembly, the connection between the guide plate and the actuating element is so strong that an unintentional relative movement of these two elements is prevented. For this purpose, in the known system, the mutually associated contact surfaces of wedge element and guide plate on latch-like projections and recesses, which are aligned in the mounting position each perpendicular to the solid ground and engage each other so that the wedge element on the interlocking projections and recesses with the guide plate is positively coupled. At the same time, the vertical orientation of the projections and recesses ensures that the wedge element retains its original position even under the action of the longitudinal and transverse forces to which it is exposed during operation.

For the ability to change the position of the respective guide plate relative to the respective support surface over a certain margin, in the above-described prior art, a cumbersome assembly and disassembly of the entire system must be taken into account.

In the DE 10 2007 044 098 B3 are described a combination and a system of the type specified, in which this disadvantage no longer exists. For this purpose, in this known combination of guide plate and wedge element on the surfaces on which the guide plate and the wedge element in assembly position abut each other, positively interlocking projections and recesses formed, which extend parallel to the top of the flat solid ground in the assembled state of the wedge element , The in practice in mounting position accordingly horizontally oriented projections and recesses allow wedge element and guide plate against each other to move without the need to disassemble the entire rail fastening system. Thus, in the known combination, the wedge element can already be displaced after releasing the clamping forces acting on the guide plate. By contrast, under the action of the clamping forces, the angle guide plate exerts a compressive force directed against the solid ground on the wedge element, as a result of which self-locking occurs in the region of the positive connection between guide plate and wedge element. This effect can be enhanced by the fact that at the mutually associated surfaces of guide plate and wedge element a plurality of forward / return pairs are formed and to the Guide plate a shoulder is formed, which presses in the fully assembled state on the wedge element.

The advantages achieved with the above-described embodiment is in practice the disadvantage of the fact that even with her the installation is comparably difficult. Thus, the guide plate must first be arranged on the respective substrate and then the wedge element must be accurately positioned on the guide plate. The wedge member then loosely abuts the guide plate until the rail is seated and the wedge member is held between the rail foot and the guide plate. It comes under the harsh, prevailing in practice on the track construction site conditions again and again to the fact that the wedge element accidentally slips by collision with the rail or other object and thus complicates its positionally accurate alignment. This is especially true if the assembly of the known system to be made fully or partially automated.

Against this background, the object of the invention was to provide a combination of guide plate and wedge element, which is particularly suitable for automatic assembly. In addition, a suitably designed system for securing a rail should be specified.

A combination of guide plate and wedge element that achieves this object according to the invention has the features specified in claim 1.

With regard to the system, the solution according to the invention of the above-stated object is that such a system is designed according to claim 9.

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

A combination according to the invention consists, as in the initially cited prior art, of a guide plate for laterally supporting a rail for a rail vehicle and a wedge element for adjusting the position of the rail relative to an abutment on which the guide plate is supported in the assembly position. In this case, the guide plate has a wedge element associated, extending in the longitudinal direction of the rail to be supported end face and a bottom. This underside is assigned to a background, which carries the guide plate in the mounting position. Typically, in practice, the subfloor in question is formed by a concrete sill or slab. Between the guide plate and the wedge element, a guide in the form of a positive connection is also present in a combination according to the invention, along which the wedge element is displaceable in the longitudinal direction of the end face of the guide plate.

According to the invention, the guide between the wedge element as the one joining partner and the guide plate as the other joining partner is formed by a slit-like one aligned along this joining partner Guidance is formed, in which a correspondingly shaped projection of the other joining partner engages positively such that the wedge element in befindlichem engaged projection in a direction transverse to the longitudinal extent of the end face of the guide plate and in the direction of the underside of the guide plate direction and on the other hand in a normal to assigned to him associated end face of the guide plate direction is fixed to the guide plate.

According to the invention, the guide, via which the wedge element and the guide plate are positively connected to each other, thus formed such that when the positive connection is made, the guide plate and the wedge element only in a maximum of two degrees of freedom, namely in the longitudinal direction of the wedge element associated end face of the guide plate and in the direction of the top of the guide plate can be moved. This makes it possible to pre-assemble the wedge element and the guide plate already removed from the respective installation site, and then place together in the correct orientation for mounting at the installation site. In this way, the guide plate-wedge element combinations can be inexpensively preassembled in large numbers and then easily placed, for example, by an automatically operating gripper at the assigned mounting location. During transport of the combinations of the place of pre-assembly to the mounting location hangs in accordance with the horizontal orientation of the guide plate, the wedge member even under the action of gravity safely on the guide plate, without requiring a separate backup of the maintenance of the wedge element on the Guide plate must be made. Thus, the longitudinal displacement is always maintained. Therefore, once the appropriate cohesive combination is placed at the mounting location, the wedge member can be easily moved to the required position to provide an optimally aligned abutment surface for the lateral support of the rail.

As a result, with the invention, a combination of a guide plate and a wedge element is available, with the simplest possible means a partially or fully automatic, trouble-free installation is possible without the need for restrictions on the actual functionality of this combination must be taken into account.

The shape of the guide provided according to the invention is fundamentally subject to no restrictions as long as it is ensured that it is able to absorb the moment which acts as a result of the gravitational force or the dead weight of the wedge element hanging on the guide plate in the area of the positive connection between guide plate and wedge element. As guides of this type, for example, a molded into the one partner, laterally open T-slot or the like in question, in which engages a correspondingly adapted projection of the other connection partner. The pre-assembly of the combination then takes place in that the projection is inserted over the lateral opening in the guide. The advantage of a cross-sectionally T-shaped or comparable shaped design of leadership and in the leadership cross Advantage is that acting through the top and bottom, the guide at its respective end face outwardly limiting webs on the one hand a particularly secure support provided with the projection connection partner to the other connection partner during transport from the pre-assembly to the installation site and a particular precise guidance is ensured in the subsequently necessary if necessary longitudinal displacement of a connection partner relative to the other.

A further simplified pre-assembly with good grip can be achieved in accordance with a practical embodiment characterized in that the guide is formed in the guide plate and formed in the manner of a slot, the slot opening in the direction of the underside of the guide plate opposite free upper side of the guide plate is aligned. In this case, the wedge element can be hooked with his in this embodiment in cross-section hook-shaped projection coming from above in the groove-like guide. The potentially cumbersome threading of the projection over a lateral opening of the guide is eliminated. Of course, it is also possible with basically the same effect, to introduce the slot-shaped guide in the wedge element and to form the projection on the guide plate. However, it is advantageous in terms of handling when the larger guide plate is used as a holder, in which the wedge element is hooked.

The web which delimits the slot-shaped guide does not necessarily have to extend over the entire length of the guide. Instead, it may be sufficient if the respective web extends only over one or more sections of the length of the guide and it is ensured that at the web or the webs a sufficiently large contact surface for the projection engaging in the guide is present. Optimum hold and guidance during the longitudinal displacement arise in practice when the web extends over the entire length of the end face.

A snug fit and precise guidance of the wedge element on the guide plate arise when the protruding into the guide plate as a slot-shaped guide projection of the wedge element is designed as a paragraph formed in the associated from the bottom of the wedge element forth a slot is limited on its outer side by a web, and if the width of the formed on the projection of the wedge member slot except for a required for the displacement of the wedge member on the guide plate excess of the width of the web, which limits the slot-shaped guide plate guide , or the width of the web which delimits the slot of the projection of the wedge element is adapted to the width of the slotted guide of the guide plate, except for an undersize required for the displaceability of the wedge element on the guide plate.

In the case that the guide is open to the top of the guide plate or wedge member slot is formed can, characterized in that at least one stop is provided, the at the form-fitting with the guide plate wedge element

Limited relative mobility of wedge element and guide plate in the direction of the top of the guide plate, unintentional release of the positive connection between the guide plate and wedge element are reliably prevented even under the loads occurring in practical use. Preferably, the stop is formed on the guide plate due to the existing there larger space to allow its most stable design.

The positionally accurate alignment of guide plate and wedge member relative to each other can be simplified in that on the guide plate and the wedge member associated bearing surfaces are formed, which extend along and across the associated end faces of the guide plate and wedge member and where the guide plate and wedge member in the form-locking coupled together touch each other. By mutually correspondingly shaped marks are formed on the bearing surfaces, the form-fitting releasably mark in each case a certain position of the wedge element with respect to the guide plate with mutually positively coupled guide plate and wedge element, certain setting steps can be specified in a particularly simple manner in which the positioning of Guide plate and wedge element relative to each other. The advantage of arranging the marks on the pointing in the direction of the top or the bottom of the guide plate or the wedge member Bearing surfaces consists in that for a displacement of the guide plate and the wedge member relative to each other, the positive connection between the marks can be solved by a slight lifting one of the connection partners, without affecting the leadership of the wedge member on the guide plate or a disassembly of the invention Combination must be made on a larger scale.

The assembly and adjustment of a system according to the invention can additionally be facilitated by the fact that at least one stop projection is provided on the guide plate, which cooperates positively with a recess of the wedge member to define a "0" position of the wedge member. Starting from this "0" layer can then be made easily the proper alignment of the wedge element. It can thereby be ensured that the wedge element is held securely to the respective stop projection by the fact that the recess is laterally bounded by laterally flat running webs, which are designed in the manner of a run-on slope. On the other hand, it is just as possible to move the wedge element non-destructively from the relevant "0" position with little effort in the required position.

A captive for the wedge element on the guide plate can be accomplished in a simple manner that on the wedge element end stops are formed, which upon reaching a Verschiebeendlage the wedge element with the stop projections interact positively.

The in Fig. 1 The attachment point shown comprises two identically constructed systems S1, S2 for fastening a rail S to a substrate U formed by a concrete threshold. The one system S1 is positioned on one side and the other system S2 on the other side of the rail S to be fastened , In Fig. 1 is located there the left longitudinal side of the rail S associated system S1 in the fully assembled position, while the in Fig. 1 the right longitudinal side of the rail S assigned system S2 is pre-assembled.

Each of the systems S1, S2 comprises a guide plate 1, a wedge element 2, an ω-shaped tension clamp 3, two adapter pieces 4,5, one of which is arranged on one of the free ends of the retaining arms 6,7 of the tension clamp 3, and a Clamping screw 8 for clamping the clamp 3 against the ground U.

The one-piece made of a plastic or other sufficiently firm material made guide plate 1 has the basic shape of a conventional angled guide plate and has a first end face 9, which is associated with the rail foot F of the rail S, and a second end face 10, which on the front side to the 9th opposite side of the guide plate 1 is formed and over which the guide plate 1 in the assembled position ( Fig. 1 ) on one at the firm underground U is supported in the form of a shoulder formed counter bearing G.

The first end face 9 is arranged obliquely with respect to the second end face 10 such that its extensions, which are intended to be longitudinal in the direction L, intersect at an acute angle.

On the underside 11 of the guide plate 1, a support surface 12 is formed, with which the guide plate 1 is seated in the mounting position on the guide plate 1 associated contact surface of the flat surface U. Towards the second end face 10, the contact surface 12 is bounded by a projection extending over the length L1 of the guide plate 1, which sits in a manner known per se when the guide plate is completely assembled in a correspondingly shaped groove, not visible here, which is located between the abutment G and the contact surface of the underground U is arranged.

Starting from the bearing surface 12, recesses 13 are formed in the guide plate 1 to minimize the weight and the material required for the production, which extend into the lower region of the first end face 9 bordering on the underside 11. In this case, the guide plate 1 is stiffened in the region of the recesses 13, inter alia by transverse to the end faces 9,10 aligned ribs 14,15 in the manner of a vault structure, so that with minimized material requirements optimal stiffness is secured.

At approximately the middle height of the first end face 9, a shoulder 16 extending over its length L1 is integrally formed on the first end face 9 and delimits the openings of the recesses 13 assigned to the end face 9 upwards.

To set back a certain small distance relative to the end face of the shoulder 16 a web 17 is additionally formed on the end face 9, which also extends over the length L1.

The web 17 defines outwardly a slot-like guide 18, which is formed in the end face 9 of the guide plate 1 and also extends over the entire length L1 of the guide plate 1. The guide 18 has the shape of a laterally open groove with a substantially rectangular cross-section. In the direction of the second end face 10 of the guide plate 1, the slot-shaped guide 18 is bounded by a wall 19 a of a central shoulder 19 of the guide plate 1.

At the free, upwardly facing top of the web 17 a parallel to the flat bearing surface 12 aligned bearing surface 20 is formed on the at regular intervals marks 21 are formed in the form of locking webs, with low height and transverse to the longitudinal direction L of the guide plate. 1 raised above the bearing surface 20 raise.

In the region of the corners between the first end face 9 and the lateral walls 22, 23 of the guide plate 1, a stop 24, 25 is integrally formed on the central shoulder 19. Each of the attacks 24,25 rises on the one hand over a certain height on the present at the top 26 of the guide plate 1 surface 27 of the central portion 19 and on the other hand in the direction of the first end face 9 before.

Starting from the surface 27, a through hole 28 leading to the underside 11 is formed in the guide plate 1, through which the clamping screw 8 is inserted for bracing the tension clamp 3 in a conventional manner.

To optimize the electrical insulation, the passage opening 28 is surrounded on the surface 27 by a circumferential collar 29. This prevents accumulating liquid on the surface 26 into the through hole 28 and there forms an electrically conductive bridge to the substrate U. At the same time, the circumferential collar 29 serves as a guide and support for the middle loop 38 of the tensioning clamp 3 mounted on the guide plate 1.

In order to prevent liquid from entering the passage opening 28 via the tensioning clamp 3, run-off slopes 29 a are formed on the collar 29. These are formed sloping starting from the inner edge of the collar 29 in the direction of the walls 22,23, so that water or other liquid that passes there from the tension clamp 3 on the guide plate 1, is laterally derived on the surface 27 of the guide plate 1. The surface 27 itself is also sloping slightly sloping towards the second end face 10, so that on them reaching liquid can flow in the direction of the second end face 10.

Towards the second end face 10, the surface 27 of the guide plate 1 is delimited by a groove 31 extending in the longitudinal direction L, in which the torsion sections 32, 33 of the tension clamp 3 are seated in a manner which is also known per se. Also, the bottom of the grooves 31, which are open at their ends 22,23, can be divided, starting from the middle of the groove 31, into two inclined surfaces, one of which slopes towards one wall 22 and the other towards the other wall 23.

The groove 31 is followed by a support shoulder 34 in the direction of the second end wall 10. Whose surface is also divided by the nature of the roof surface of a gable roof in two surface halves 35,36, one of which in the direction of one wall 22 and the other in the direction of the other wall 23 drops. Correspondingly, fluid also impinges on the surface halves 35, 36 likewise laterally from the guide plate 1.

In addition, the support shoulder 32 carries at its end face 10 associated edge extending over the length L32 skirt 37 which protrudes upward over the surface halves 35,36 and is shaped so that they are ready mounted guide plate 1 with its second end face 10th assigned outer surface is flat on the anvil G. Through the skirt 37 is the ready mounted guide plate 1 between the anvil G and the support shoulder 32 unavoidable joint gap covered so that in particular of the surface halves 35,36 no liquid can penetrate into it. The skirt 37 thus forms an effective barrier against the otherwise favored by the capillary effect penetration of liquid into the respective joint gap or the porous material of the substrate U. In this way, the skirt 37 also contributes to the optimized insulation of the generally made of electrically conductive steel Tension clamp 3 and, consequently, the rail S also made of electrically conductive steel with respect to the substrate U at.

The wedge element 2 is also made in one piece from plastic or other sufficiently strong material. It has a wedge-shaped in plan view with a rail F associated first flat end face 50 and one of the guide plate 1 associated second end face 51. The two end faces 50, 51 of the wedge element 2 run obliquely toward one another in such a way that their extensions projected in the longitudinal direction L intersect at the same angle as the extensions of the end faces 9, 10 of the guide plate 1 intended in the longitudinal direction L. In the case of the guide plate 1 Wedge element 2, the first end face 50 of the wedge element 1 and the second end face 10 of the guide plate 1 are aligned parallel to each other accordingly. The length L2 of the wedge element 2 is approximately twice the length L1 of the guide plate. 1

To the second, the guide plate 1 associated end face 51 of the wedge member 2 is a over the length L2 extending projection 52 formed. The projection 52 carries at its free end in the direction of the bottom 53 of the wedge member 2 facing, also over the length L2 extending web 54. The web 54 defines outwardly a groove-shaped, formed from the bottom 53 forth in the projection 52 guide slot 55th which is open to the bottom 53 and its lateral ends. The guide slot 55 has a substantially rectangular cross section and is bounded on its side opposite the web 54 by the wall of a main body 56 of the wedge element 2. At the bearing surface 57 forming a roof surface of the guide slot 55 marks 58 are formed in the form of slit-shaped depressions at regular intervals, which are aligned transversely to the longitudinal extent of the guide slot 55 and the web 54. The distances between the marks 58 correspond to the distances between the marks 21, which are formed on the bearing surface 20 of the web 17 of the guide plate 1. Similarly, the shape and dimensions of the marks 58 are adapted to the shape and dimension of the marks 21.

From the bottom 53 forth recesses 59 are formed in the wedge element 2 for saving material and minimizing the weight, which are separated by stiffening ribs 60 from each other.

On the upper side 61 of the wedge element 2, spacing markings 62 are provided on the edge of the projection 52 assigned to the guide plate 1. The spacing marks 62 on the guide plate 1 a fixedly positioned, on the wedge element 2 associated edge assigned to the guide plate 1 wedge element 2 based on the location of the distance marks 62 with respect to the arrow mark 39 can be read in which position the wedge element 2 is relative to the guide plate 1.

In addition, starting from the upper side 61, a recess 63 is formed in the wedge element 2 at a central location. In the recess 63, a tool for lifting the wedge element 2 can be introduced.

The conventionally formed ω-shaped tension clamp 3 has on its support arms 6,7 each have a bent end portion, which is aligned with the assembled system S1, S2 substantially parallel to the rail S and applies the required hold-down force on the rail foot F. On each of these end sections, an adapter piece 4, 5 is rotatably mounted about an axis of rotation coincident with the longitudinal axis of the respective end section.

Seen from its front side, the adapter pieces 4, 5 each have a pentagonal shape. At the peripheral surface of the adapter pieces 4.5 each three equal contact surface portions are formed, which abut each other directly and are separated from each other by an edge. In addition, two marking sections adjoin the two outer contact surface sections. These marker sections can be provided with markings that with indicate a rotation in the respective direction associated increase or decrease of the spring tension.

The marking sections are separated by a slot which is formed from the radial direction into the adapter pieces 4, 5 and extends into a receptacle which is formed from its one end face into the adapter pieces 4, 5. The slot intersects a triangular opening in the bottom of the receptacle so that moisture or vapors that collect in the receptacle can escape through the opening from the respective adapter piece 4, 5.

The center of the circular opening of the receptacle is arranged offset relative to the center of the end faces of the adapter pieces 4.5, that the first contact surface portion a first distance z1, the second contact surface portion a second distance z2 and the third contact surface portion a third distance z3 to the center of Has admission, where z1 <z2 <z3. The distances z1 - z3 differ, for example, by one millimeter each.

The adapters 4.5 are made of an electrically non-conductive plastic, which has a certain elasticity at least in its circumferential direction.

In the relaxed state, the receptacle of the adapter pieces 4, 5 has a diameter that is smaller by a small undersize than the likewise circular end portions of the retaining arms 6, 7. When attaching to the end portions, the adapter pieces are spread accordingly in the circumferential direction, so that they in consequence of the in the adapter pieces 4.5 then acting restoring forces frictionally engaged, but still held with a certain amount of force rotatably on the respective associated end portion. The spreading of the adapter pieces 4,5 can be done easily due to the slot, which prevents in this way not only the accumulation of moisture in the respective adapter piece 4,5, but also attaching the adapter pieces 4,5 on the respective end portion of the support arms. 6 , 7 facilitates and ensures their sufficient elastic compliance.

The clear width between the stops 24,25 and formed on the bearing surface 20 marks 21 of the guide plate 1 is so adapted to the between the bearing surface 57 and the top 61 associated surface 62 of the wedge member 2 remaining thickness and the height of the web 54 in that with the guide 18 engaged projection 52, the wedge member 2 can be raised by a height sufficient to release the positive connection between the marks 20 of the guide plate 1 and the marks 58 of the wedge member 2, to further longitudinal adjustment of the wedge member 2 relative to the guide plate 1 make.

The measured transverse to the longitudinal direction L width of the web 17 and the guide slot 55 and also measured transversely to the longitudinal direction L width of the web 54 and the slot-shaped guide 18 are adapted to each other so that when the projection 52 with its web 54 in the guide 18 and the web 17 engage positively in the guide slot 55, the wedge element 2 with little play on the guide plate 1 in the longitudinal direction L. slidably guided. At the same time, the form-fitting connection produced via the guide 18 and the projection 52 engaging in it aligns the wedge element 2 with the end face 50 on the first end face 50 of the wedge element 2, in a face normal to the first face 9 of the guide plate 1 or to the flat face Direction R1 and in a direction of the bottom 11 of the guide plate 1 facing, also oriented transversely to the longitudinal direction L direction R2 on the guide plate 1 fixed.

The combination thus formed can be easily moved in the pre-assembled state from a waiting position to the mounting location. In this case, the wedge element 2 is automatically held on the guide plate 1, so that no additional measures for the proper positioning of guide plate 1 and wedge element 2 at the installation are required.

The systems S1, S2 are pre-assembled in the same way. After discontinuation of the combination formed from guide plate 1 and wedge element 2, the tensioning clamp 3 with the adapter pieces 4, 5 seated on it is respectively placed on the guide plate 1 of the respective system S1, S2 in such a way that its torsion sections 32, 33 on the support section 34 the guide plate 1 sit. The adapter pieces 4, 5 are in this preassembled state outside the space occupied by the rail foot F after the rail S has been set down.

Subsequently, the clamping screw 8 of the respective system S1, S2 through the through hole 28 of Inserted guide plate 1 in a submerged in the underground U, not visible here plastic dowels and tightened so far that the tension clamp 3 is held with a certain bias on the guide plate 1 in its pre-assembly.

After the rail S is placed in the space defined between the wedge elements 2 of the systems S1, S2, the tension clamps 3 are displaced in the direction of the rail S until their end sections with the adapter pieces 4, 5 on the rail foot F and the torsion sections 32, 33 sit in the groove 31 of the respective guide plate 1. Then, if necessary, by appropriate longitudinal displacement of the wedge elements 2 relative to the respective guide plate 1, the position of the rail S and the existing on the wedge elements 2, the rail F associated contact surface are adjusted so that an optimal lateral support is ensured with proper orientation of the rail S. ,

If it is determined that due to an excessively large or too small height difference between the upper side of the rail foot F and the upper side of the respective guide plate 1 by a tension clamp 3, an insufficient or excessive hold-down force is exerted on the rail foot F, this can be compensated by the fact that the respective tensioning clamp assigned adapter pieces 4.5 is rotated about its respective axis of rotation so that it over a contact surface portion with a smaller distance (decrease in hold-down force) or greater distance (increase in Hold-down force) is then supported on the running through the center of the recording axis of rotation on the rail foot F. The adapter pieces 4.5 thus allow a fine adjustment of the tension clamps 3 of the systems S1, S2 applied hold down forces. At the same time they isolate the clamps 3 against the rail S.

Therefore, the features of the guide plate 100, which coincide with the corresponding features of the guide plate 1, provided with the same reference numerals as in the guide plate. 1

Beyond the guide plate 1, the guide plate 100 has a stop projection 101, 102 projecting from the wall 19a at its end wall 19a delimiting the slot-shaped guide 18 in the region of the ends of the slot-shaped guide 18. The stop projections 101, 102 may, as shown here, have the basic shape of a cuboid with comparably sharp edges between their free end face and their side faces. In each case one of the stop projections 101, 102 is arranged in the region of the wall 19a, above which the stops 24, 25 rise.

Therefore, the features of the wedge member 110 that correspond to the corresponding features of the wedge member 2 are provided with the same reference numerals as in the wedge member. 2

In addition, two recesses 111, 112, which are bounded laterally in each case by a web 113, 114, are formed at the end face 51 of the wedge element 110 associated with the wall 19a of the guide plate 100 at a distance from one another and from the lateral ends of the end face 51. The distance of the webs 113,114 is selected so that the stop projections 101,102 in the case that one of the recesses 111,112 is brought by moving the wedge member 110 in the slot-like guide 18 of the guide plate 100 with them, with positive and with little play in the recess in question 111,112 grab. In this case, the webs 113,114 are formed laterally flat in the manner of a run-on slope, so that they take into account the certain, normal to the wall 19a game with which the wedge member 110 is guided in the guide 18, upon displacement of the wedge member 110 the respective stop projection 101,102 postpone and the relevant stop projection 101,102 can be overcome with a certain resistance. The stop projections 101,102 thus constitute, in cooperation with the recesses 111,112 latching marks, are defined by the two "0" layers, starting from which the respective adjustment of the wedge member 110, for example, to compensate for assembly inaccuracies can be made.

At the lateral ends of the end face 51 of the wedge element 110 there is provided in each case an end stop 115, 116 whose side face 117 facing the respective other end stop 116, 15 is aligned essentially at right angles to the end face of the end face 51 that is otherwise planar. In the event that the end stops 115,116 when moving the wedge member 110 in the guide 18 of the guide plate 1 against the respective associated stopper projection 101,102 abut, so is the associated side surface of the respective stop projection 101,102 close to the respective side surface 117 of the respective end stop 115,116. Due to the fact that the side surface 117 of the respective end stop 115, 116 and the side surface of the respective stop projection 101, 102 adjoining it are aligned parallel to one another and perpendicular to the wall 19 a or to the end face of the end face 51, the end stops 115, 116, in contrast to the webs 113, 114 not overcome the stop projections 101,102 non-destructive. In cooperation with the respectively associated end stop 115, 116, the stop projections 101, 102 thus form a safeguard against unintentional falling out of the wedge element 110 from the guide 18 of the guide plate 100. reference numeral Component / form element 1,100 guide plates 2 key member 3 tension clamp 4.5 insulators 6.7 Retaining arms of the tension clamp 3 8th clamping screw 9 first face of the guide plate 1,100 10 second face of the guide plate 1,100 11 Bottom of the guide plate 1,100 12 Bearing surface of the guide plate 1,100 13 Recesses of the guide plate 1,100 14.15 Ripping the guide plate 1,100 16 Paragraph of the guide plate 1,100 17 Bridge of the guide plate 1,100 18 Guiding the guide plate 1,100 19 central shoulder of the guide plate 1,100 19a the guide delimiting wall 19a of paragraph 19 20 Bearing surface of the guide plate 1,100 21 Brand of guide plate 1,100 22.23 Walls of the guide plate 1,100 24.25 Stops of the guide plate 1,100 26 Top of the guide plate 1,100 27 Surface of the central portion 19 28 Passage opening of the guide plate 1,100 29 Collar of the guide plate 1,100 30 Drainage slopes of the collar 29 31 Groove of the guide plate 1,100 32.33 Torsionsabschnitte the tension clamp 3 34 Support shoulder of the guide plate 1,100 35.36 Surface halves of the support shoulder 34 37 Apron of the guide plate 1,100 38 Middle loop of the tension clamp 3 39 arrow mark 50 first end face of the wedge element 2 51 second end face of the wedge element 2 52 Projection of the wedge element 2 53 Bottom of the wedge element 2 54 Bridge of the wedge element 2 55 Guide slot of the projection 52 56 Main body of the wedge element 2 57 Bearing surface of the wedge element 2 58 Marks of the wedge element 2 59 Recesses of the wedge element 2 60 Stiffening ribs of the wedge element 2 61 Top of the wedge element 2 62 distance markers 63 recess 100 guide plate 101,102 stop projections 110 key member 111,112 Recesses of the wedge element 110 113,114 Stege 115,116 End stops of the wedge element 110 117 the end stop 115 facing side surface of the end stop 116th F rail G thrust bearing L longitudinal direction L1 Length of the guide plate 1 L2 Length of the wedge element 2 R1 direction R2 direction S rail S1, S2 Systems for fastening the rail S U underground
