Description

The invention relates to an angled guide plate for mounting a rail on a substrate, with a recess which serves as a seat for a free end portion of a spring arm to be mounted on the angled guide plate clamp, as long as it is in the preassembly, wherein the recess to the end portion to less than half of its circumference.

Likewise, the invention relates to a system for securing a rail on a substrate, said system having an angled guide plate, arranged on the angled guide plate W-shaped tension clamp having at least one spring arm, which acts with its free end portion on the rail to be fastened, and a Clamping means for clamping the tension clamp against the ground comprises.

As explained in the brochure published by the applicant "Rail fastening systems for concrete sleepers - System W 14", angled guide plates and fastening systems of the type in question are used in the attachment of rails on a solid surface, for example by a concrete sleeper or a concrete slab may be formed. The rail to be fastened stands on an elastic intermediate layer directly on the solid ground. Laterally, the rail is guided by angled guide plates, which form in pairs between them a track-accurate rail channel. See also EP 0 733 433 A1 ,

In the known fastening systems of the aforementioned type, the forces introduced via the rail are conducted via the angled guide plate directly into the substrate supporting the rail. For this purpose, a shoulder is formed on the respective substrate for each of the angled guide plates, on which the associated angle guide plate is supported.

On the angled guide plate usually a W-shaped clamp is mounted, which presses in the assembled state with the free end portions of their spring arms on the free top of the rail foot of the rail to be fastened. At one of their free end portion respectively opposite, curved and supported on the angled guide plate support portion, the spring arms of the tension clamp go into an over-center loop, which is clamped by a clamping screw against the solid ground.

The U-shaped middle loop of the clamp surrounds the clamping screw. Their legs are designed so that the tension clamp with pre-assembled, a reduced contact force exerting clamping screw from a pre-assembly, in which the free end portions of the spring arms of the tension clamp on a parallel to the rail to be mounted extending rib and its support portions sitting on a respective shoulder of the solid surface associated surface can be pushed into the mounting position, wherein the spring arms act on the rail and the support portions of the tension clamp in one in the angled guide plate for molded, usually groove-shaped recess sitting.

In order to secure the secure fit of the tensioning clamp in the preassembly position, a throat is usually formed on the side facing away from the rail to be mounted in the ribs assigned to the free end sections of the spring arms of the tensioning clamp. Their shape is chosen so that the free end portions of the pre-assembled tension clamp sit form-fitting in them. The throat goes in a sharp-edged angle in the plane, usually parallel to the ground associated with the footprint of the angled guide plate extend the top of the rib. In this way it is ensured that the tension clamp can be brought from its pre-assembly in the final assembly position only by overcoming a certain resistance over the edge between the throat and the rib top. Such unintentional movement must be prevented, otherwise there is a risk that the tensioning clamp will already protrude into the space provided for the rail before the rail is positioned. The proper positioning of the rail would be hampered.

However, the assembly of the known rail fastening systems is complicated by the fact that the clamping screw that holds the tension clamp in its pre-assembly, must be solved by an amount to move out the end portions of the throat of the rib and push the tension clamp from the pre-assembly in the final assembly position can , This need proves to be particularly disadvantageous in practice because rail fasteners of the type described above are generally installed in large numbers with the aid of automatically operating mounting devices. Their operation is further complicated by the dissolution process.

Against this background, the object of the invention was in at least one angle guide plate comprehensive rail fastening systems of the type described above in a simple way, on the one hand to ensure proper retention of the tension clamp in its pre-assembly and on the other hand to facilitate the final assembly.

The invention has achieved this object by a designed according to claim 1 angle guide plate. Advantageous embodiments of the angled guide plate according to the invention are specified in the dependent claims on claim 1.

Likewise, the above object has been solved by a system for fastening a rail, which according to the invention has the features specified in claim 10. Advantageous embodiments of the Mounting system according to the invention are specified in the back claim to claim 10.

In accordance with the prior art, an angle guide plate according to the invention for mounting a rail on a substrate on a recess. In a preassembled fastening system according to the invention sits in this recess of the free end portion, with which the spring arm of the angle guide plate to be arranged on the tension clamp in the assembled state exerts the spring force required to hold down on the rail. Also in accordance with the prior art, the recess is thereby formed so that it engages around the end portion to less than half of its circumference. In this way, although the end portion of the respective spring arm in the pre-assembled position sitting positively in the recess. However, the shape of the recess allows it to push the end portion of the recess without having to displace material of the angled guide plate.

Now, according to the invention, the transition between the recess and at least adjoining the recess in the direction of the rail to be mounted portion of the angled guide plate is formed without jolts, a shape of the angled guide plate is achieved by the one hand ensures that the tension clamp securely held in its pre-assembly is. On the other hand, the inventive design of the angle guide plate allows the tension clamp from this position in the Push final assembly position, without that it is necessary to release the clamping device, which already in the pre-assembly exerts the required for the secure retention of the tension clamp in its pre-mounting position on the tension clamp. Thus, it has been found that with a sufficiently soft or flattened transition it is possible to push the tension clamp out of the recess by utilizing its own resilient compliance, although at the same time relatively high holding forces are exerted by the tensioning means. At the same time, it has been found that these holding forces can easily be so high that the tension clamp is held with a safety that is sufficiently high in practice in the pre-assembly position determined by the recess of the angled guide plate.

With the invention, it is thus possible in an extremely simple way, an angle guide plate and with it a rail fastening system so that clamp not on the one hand automatically moved out of its pre-assembly, but on the other hand, a single operation, namely the release of the clamping means before moving the tension clamp in the Final assembly, saved.

In the event that an inventive angle guide plate in accordance with the prior art has a along a contact surface extending, in the fully assembled state on the rail to be fastened rib, also as in the prior art in an inventive Angle guide plate, the recess may be formed in the rib. In order to make it easier to move the tension clamp from the pre-assembly into the final assembly position and yet to ensure a secure fit in the pre-assembly, according to the invention on the side facing away from the contact surface of the rib a starting from the surface of the rib-carrying main portion of the angled guide plate be formed obliquely to the top of the rib rising ramp, in which the receptacle is formed. In this arrangement of the recording, the spring arms of the tension clamp when moving from the pre-assembly in the final assembly position must be additionally braced by a certain amount, whereby the security with which the tension clamp sits in its pre-assembly, is additionally increased. The amount by which the spring arms are additionally braced, is dependent on the height difference between the receptacle and the tip of the rib over which the end portion of the spring arm must be pushed. Due to the fact that the transition between the receptacle and the portion of the angled guide plate over which slides the end portion of the spring arm in the displacement from the pre-to the final assembly position, according to the invention is formed jump-free, it is ensured that the required deformation of the spring arm automatically adjusted when the tension clamp is moved in a rectilinear movement in the direction of the rail. A release of the clamping device from the pre-assembly is not required.

The inventive jump-free transition from the recording in the adjacent portion of the angled guide plate For example, it can be accomplished by rounding off the transition between the receptacle and the adjacent sections of the ramp. The rounded shape has the advantage that the receptacle can be formed as a recess with a defined edge zone, which must be overcome by the respective end portion in a sliding movement and thus constitutes an effective obstacle against an automatic movement of the tension clamp from its pre-assembly.

A further possibility of the inventive design of an angled guide plate in the case that the angle guide plate has a rib, in that the receptacle adjacent to the dome, then in the context of the invention, the transition from the receptacle to the rib tip is formed jump-free. For this purpose, the dome itself may have a rounded cross-sectional shape. This embodiment has the advantage that the tension clamp with the end portion of its spring arm can still slide smoothly on the rib even if the end portion has exceeded the dome of the rib on its way to the final assembly position.

The transition of the end portion of the spring arm on the rail of the rail to be fastened can thereby be facilitated that in a conventional manner at the front of the rib associated with the rail to be mounted from the top of the rib obliquely up to the voltage applied to the rail contact surface leading sliding surface is formed for the end portion of the tension clamp.

In order to avoid the risk of excessive wear during assembly of the tensioning clamp or during operation in the region of the surface sections in which the tensioning clamp comes into contact with the angled guide plate, the angled guide plate can have a wear-resistant material in at least one of the relevant surface sections. This is particularly useful in those places where it comes to when moving in the course of assembly postponement of the tension clamp or during operation due to the running of the clamp spring movements relative movements between the angled guide plate and the tension clamp. This can be accomplished particularly cost-effectively by applying the wear-resistant material to the respective surface section. The wear-resistant material can also be used in the form of inserts in appropriately prepared recordings of the angle guide plate. It is also conceivable to manufacture the entire section of the angled guide plate assigned to the respective surface section from such a wear-resistant material.

Particularly advantageous effects of the invention in the attachment of rails on a substrate, which is formed by a concrete sleeper or a concrete slab. This is especially true when a shoulder is formed on the substrate, on which the angle guide plate is supported.

In order to secure the pre-assembled on the angle guide plate according to the invention spring element against rotation during pre-assembly, a stop surface may be formed on the angled guide plate, which supports the respective free end portion of the spring element. The abutment surface may be aligned such that it defines the receptacle together with an associated surface portion of a ramp formed on the angled guide plate, in which the respective end section is seated in the preassembly position. For this purpose, the stop surface may be formed on a hump-like projecting, formed on the top of the angled guide plate survey.

That in the FIGS. 3 and 4 shown system 1 is used to attach a rail on a solid surface U, which is formed in the present example by a sake of clarity here only incomplete concrete sleeper 3 shown. For the same reason is of the rail to be fastened in the FIGS. 3 and 4 only the edge of the rail foot 2 facing the system 1 is shown.

The system 1 comprises an angle guide plate 4, an elastic layer 5, a W-shaped tension clamp 6 provided as a spring element for generating the required holding force, and a tensioning screw 7 serving as a tensioning means for tensioning the tension clamp 6.

The elastic layer 5 consists of a finely porous, highly elastic polyurethane foam, the elasticity of which is such that it automatically relaxes automatically even after a prolonged complete compression suddenly discharge and again expands to the initial thickness of the elastic layer 5.

In the concrete sleeper 3, a recess 8 is formed, which extends over the width of the concrete sleeper 3 and which is limited at their seen in their longitudinal direction lateral ends in each case by a support shoulder 9. The bottom of the recess 8 forms a support surface 10 on which the elastic layer 5 is located. In the region of the transition from the support surface 10 to the respective support shoulder 9, a groove 10a is formed in the support surface 10 in each case. The adjacent to the groove 9 side end portion of the support surface 10 forms the area on which the angle guide plate 4 is in mounting position. At a central location, a recess is formed in this end, in which a plastic dowel, not shown here for the clamping screw 7 is seated.

The angle guide plate 4 has on its upper side 11 form elements 12 which guide the tension clamp 6 and ensure a secure transmission of the holding forces on the rail 2 to be held by the system 1 rail. Starting from its upper side 11, a passage opening 13 is additionally formed in the angled guide plate 4. Through this opening 13, the clamping screw 7 is guided to tension the tension clamp 6 during assembly in a manner already known per se, in order to screw it into the seated in the threshold 3 dowels.

At its end face assigned to the rail foot 2, the angled guide plate 4 has a contact surface 14, with which the angled guide plate 4 bears laterally on the rail foot 2.

On the upper side 11 of the angled guide plate 4, a rib 15 is formed, which extends along the rail 2 associated edge of the angled guide plate 4 and is aligned with its the rail 2 associated side flush with the contact surface 14. In the middle, table-like section 16 of the rib 15, the respective mold element 12 is formed, which leads the tension clamp 6 in its finished mounting position. By contrast, the two sections 17a, 17b of the rib 15 adjoining the middle section each have a narrow dome 18 rounded in cross-section, which merges into the contact surface 14 in a tapered sliding surface 19 on the side of the rib 15 assigned to the rail foot 2.

On its side facing away from the rail 2 side, the side portions 17 a, 17 b, however, shaped in the manner of a ramp 20 which extend obliquely from the top 11 of the angled guide plate 4 to the respective dome 18.

In the ramp 20 is in each case over the respective section 17a, 17b extending trough-like receptacle 21a, 21b formed. Their shape is adapted to the outer diameter of the free end portions 22 of the spring arms 23 of the tension clamp 6 so that the end portions 22 can lie positively in the respective receptacle 21a, 21b and the respective receptacle 21a, 21b they each only about 30 ° touched their scope.

The receptacles 21a, 21b each go gently rounded in the surrounding sections 24,25 of the ramp 20 over. In this way, a jump-free transition from the receptacles 21a, 21b is created in particular to the section 24, which leads from the receptacle 21a, 21b to the crest 18 of the rib 15, in which he then passes without jumps. The tension clamp 6 associated top of the ramp 15 accordingly has a total jump-free course.

In order to minimize the wear in the surface portions 29,30, in which there is a relative movement between the angled guide plate 4 and the tension clamp 6 during assembly and operation, for example, the surface portion 29 on which the respective end portion 22 of the spring arms 23rd the tensioning clamp 6 moves in the region of the receptacles 21a, 21b, is covered with a wear-resistant material 31. Likewise, in the region of the surface portion 30 on which the W-shaped tension clamp 6 slips into the groove 28 during assembly with its respective reversing arcs between its middle loop and its spring arms 23, it can be applied with wear-resistant material 32. In this case, the wear-resistant material 31, 32 can be adhesively bonded to the angled guide plate 4 by spraying or another suitable application method, so that it holds sufficiently firmly on the angled guide plate 4 even under the harsh conditions prevailing in practice.

For the pre-assembly of the system 1, the angle guide plate 4 is set on the support surface 10 of the concrete sleeper 3, that in a conventional manner on the underside of the angled guide plate 4th formed projection 4a positively engages in the groove 10a of the concrete sleeper 3 and the angle guide plate is supported with its contact surface 14 opposite side of the support shoulder 9 of the concrete sleeper 3. The angle guide plate 4 is now aligned so that the passage opening 13 of the angle guide plate 4 is aligned in alignment with the seated in the threshold 3, not visible here dowels.

Subsequently, the W-shaped clamping clamp 6 is placed on the angled guide plate 4, that their spring arms 23 with their free end portions 22 in each case one of the molded into the ramp 20 of the rib 15 receptacles 21a, 21b. By screwing the clamping screw 7 in the dowel, not shown, then the tension clamp 6 is tensioned until the tension clamp 6 is braced so far that it is held in the pre-assembly position.

In a corresponding manner, an identical to the system 1 constructed, here also not shown second system is pre-assembled on the opposite side to the support shoulder 9 of the receptacle 8. In the laterally delimited by the contact surfaces 14 of these two systems space then the rail is set. Your rail 2 is thereby, as shown in the figures for the system 1, laterally on the contact surfaces 14 of the angled guide plate 4 of the respective system 1 at.

For final assembly of the system 1, the tension clamp 6 is unchanged with the aid of a not shown here, automatic mounting device tightened clamping screw 7 is pushed in a rectilinear movement L in the direction of the rail foot 2. The resilient spring arms 23 of the tension clamp 6 slide under slight additional tension with their respective end portion 22 with little resistance from the respective receptacle 21a, 21b on the adjacent portion 24 of the ramp 20 until they have reached the rounded tip 18 of the rib 15.

Subsequently, the end portions 22 slide over the adjoining the tip 18 sliding surface 19 and from there to the rail 2. This movement is continued until the tension clamp 6 with their spring arms 22 with the middle loop 26 of the tension clamp 6 connecting support portions 27 in a along the resting on the support shoulder 9 portion 28 of the angled guide plate 4 extending groove 29 sits.

Due to the special shape of the transition of the receptacle 21 a, 21 b to the dome 18 of the rib 15 and the rounding of the dome 18 itself, the displacement of the tension clamp 6 from the pre-assembly ( Fig. 3 ) to the final finished final assembly position substantially free of sudden force jumps in one go. The tension of the tension clamp 6 by the clamping screw 7 does not need to be solved because the resilient flexibility of the spring arms 22 of the tension clamp is sufficient to perform the movements required to move to overcome the dome 18 of the rib 15.

In Fig. 5 a variant of the above-described system for attaching a rail, not shown here is shown. This system also includes an angle guide plate 50 whose basic shape corresponds to the basic shape of the angled guide plate 4. Accordingly, the angle guide plate 50, as shown Fig. 5 and 6 can be seen, a not shown the rail of the rail to be mounted, the contact surface 14 of the angled guide plate 4 corresponding contact surface 50a, adjacent to the contact surface 51a, the rib 15 of the angled guide plate 4 corresponding rib 51 with one of the ramp 20 of the angled guide plate 4 corresponding ramp 52nd and a formed in the angled guide plate 50, the through hole 13 of the angled guide plate 4 corresponding through hole 53 and a middle, table-like, the portion 16 of the angled guide plate 4 corresponding portion 54 on which a mold member is formed, which is to be mounted on the angled guide plate 50 Clamp 60 leads in its finished mounting position.

Unlike the angled guide plate 4, however, in the angled guide plate 50, the ramp 52 of the rib 51 has two planar ramp surfaces 52a'52a ", one of which is disposed between one of the narrow sides 50b ', 50b" and the central portion 54 of the angled guide plate 50. The ramp surfaces 52a ', 52a "extend as seen in side view from the foot of the ramp 52 obliquely in the direction of the tip 51a of the rib 51st

In addition, on the upper side 55 of the angle guide plate 50 is offset laterally of the middle portion 54 and immediately adjacent thereto in the direction of one of the narrow sides of the angled guide plate 50 each a hump-like upwardly projecting elevation 56 a, 56 b formed. The elevations 56a, 56b have, on their side assigned to the ramp 52, an abutment face 57 running essentially parallel to the abutment surface 51, which at its lower end, assigned to the foot of the ramp 52, jumps in the manner of a throat without jolts into the respective associated ramp surface 52a '. The abutment surfaces 57, viewed in side view together with the respective associated ramp surface 52a ', 52 ", each define an angle which is smaller than 90 °.

In this way, between the stop surface 57 and the respective associated ramp surface 52a'52a "each have a recess 58a, 58b, which is formed as a seat for the respective free end portion 61 each one of the spring arms 62 of the angle guide plate 50 vorzumontierenden tension clamp 6. The abutment surfaces 57 of the elevations 56a, 56b and the associated ramp surfaces 52a ', 52a "are arranged at an acute angle to each other, that the recesses 58a, 58b at preassembled clamp 60 include the respective end portion 61 by less than half its circumference. The transition 59 between the recesses 58a, 58b and the section 52b of the planar ramp surfaces 52a ', 52a "of the angled guide plate 50, which adjoin the recess 58 in the direction of the rail to be mounted, is formed without a jump. In the pre-assembly position, the end portions 61 of the tensioning clamp 6 are seated in the respectively associated recess 58a, 58b. For biasing the tension clamp 60, a slight compressive force is exerted on the loop of the tension clamp 60 by means of a screw, not shown here, so that the tension clamp 60 can no longer move automatically from the preassembly position. In this case, the support of the free end portions 61 of the tensioning clamp 60 on the elevations 56a, 56b ensures that the tensioning clamp 60 is not twisted during tensioning but is held securely in its preassembly position. In the final assembly, the end portions 61 of the tension clamp 60 can then slide freely on the respective flat and jump-free ramp surface 52a ', 52a "until they are seated on the rail base (not shown) for the angled guide plate 4. The height H of the rib 51 can be so dimensioned that even thicker rail feet or due to corresponding documents higher standing rail feet are always reliably achieved.
