Definitions

  • the invention relates to a tensioning clamp for fastening a rail with a central portion, with at least one torsion portion extending laterally from the central portion, with at least one transition portion adjoining the torsion portion and at least one retaining arm connected to the transition portion, the free end of the support arm assigned end portion is seen in plan view of the tension clamp angled away from the torsion section.
  • Clamps of this type are usually bent in one piece from a spring steel.
  • the invention relates to a system for fastening a rail, which has a rail, a standing bridge and a rail head, with a guide plate, a clamp held on the guide plate and a clamping means for clamping the clamp against a rail supporting the base.
  • a tension clamp and a system of this kind are from the DE 10 2007 046 543 A1 known.
  • the known system is used as a spring element for generating the hold down the Rail required resilient elastic holding force is a tension clamp used, which is designed taking into account the measured in the longitudinal direction of the rail to be fastened length of the support plate so that at least one support arm can travel maximum spring travel.
  • the end portion of the support arm is angled away from the torsion section in such a way that, in the assembly position, it points in the direction of the web of the rail to be fastened.
  • the displacement of the support area in the direction of the rail web causes a higher resistance to undesired rotation, whereby in particular the correct position mounting of the tension clamp is facilitated.
  • the object of the invention was to provide a tensioning clamp and a system for fastening a rail in which, with further improved operational safety, the danger of excessive wear is reduced in the region in which the tensioning clamp acts on the rail to be fastened.
  • the solution according to the invention of the above-stated object is that such a system comprises a tensioning clamp designed according to the invention.
  • a tensioning clamp according to the invention for fastening a rail has, in accordance with the prior art described above, a middle section, a torsion section extending laterally from the central section, at least one transition section adjoining the torsion section and at least one retaining arm connected to the transition section.
  • the end portion of the holding arm associated with the free end of the holding arm is oriented angled away from the torsion portion in plan view.
  • a supporting region extending over the length of the end section is now formed on the angled end section of the holding arm.
  • the end section is angled with respect to the adjoining section of the support arm in such a way that, when the tension clamp is completely assembled, the support region rests linearly over its length on the associated surface of the rail foot of the rail to be fastened.
  • a tension clamp according to the invention therefore the end portion present on the respective support arm is bent not only towards the rail web or away from the rail web in the direction of Torsionsabitess the tensioning clamp, but it is additionally created in the region of the respective end portion an enlarged support surface through which the at clamped tension clamp between rail and end section acting surface pressures are reduced.
  • the invention goes from the Acknowledgment that in the prior art described at the outset, strong incorporations occur in the area of the contact surface, because the contact surface is restricted there to a very small area, which is also positioned near the edge of the free end side of the end section.
  • a tensioning clamp is in combination with the other components of a system according to the invention that it by the present invention at the at least one end portion linear, elongated and over the entire length of the respective end portion extending contact surface easily is possible to regulate the Track width of a track formed using a rail mounted in accordance with the invention, one rail and to combine the same tension clamp with different width guide plates.
  • the width of the guide plate is measured transversely to the longitudinal direction of the respective rail.
  • the inventive design of a tension clamp then acts when it comes as a result of wear to a displacement of the rail transversely to its longitudinal extent and relative to the guide plate on which the tension clamp is supported.
  • the inventive long predetermined, linear bearing surface in the region of each acting on the rail end portion of the clamp is ensured that even then sufficient hold-down forces acting on the rail, if between the guide plate and rail due to wear a gap has formed, the is so great that acting on the rail foot end portion projects over a portion of its length over this gap.
  • the end portion when viewed in plan view of the tension clamp, is angled away from the torsion portion so that it is directed in the mounting position against the rail web of the rail to be fastened.
  • a further increase of the hold-down force with optimized fatigue strength of the tensioning clamp can be achieved by alternatively pointing the end portion in a plan view of the tensioning clamp facing away from the torsion portion so that it is directed away from the rail web of the rail to be fastened in the assembly position.
  • the at least one retaining arm of the tension clamp is at its end the respective end portion provided with a linear contact surface and aligned is formed, longer than in the variant of the invention described in the preceding paragraphs. This leads to a greater elasticity of the support arm and concomitantly to a less heavy load, with the result that its fatigue strength is increased.
  • the holding arm can be shaped so that it is only minimally deformed in the course of the bracing. This makes it possible to align the end portion of the support arm with respect to the rest of its portion from the outset so that it sits even with a relaxed tension clamp line on the surface of the rail foot.
  • the shape and orientation of the support arm is chosen so that the arm largely serves only as a lever with low inherent elasticity, so that of the tension clamp in the tensioned state exerted spring force is generated substantially exclusively by torsion of Torsionsabitess.
  • the holding arm is aligned with respect to the torsion portion so that the torsion portion and the holding arm in an overhead view of the tension clamp from above seen an angle of 80 ° - 110 °, in particular 85 ° - 95 ° , wherein in the context of manufacturing capabilities at 90 ° approximated included angle brings optimal results.
  • the stiffness of the support arm can be optimized by an arcuate portion of the support arm extends in a plane that penetrates the torsion at an angle of 80 ° - 100 °.
  • this alignment of the arcuate portion of the support arm can be realized in that the transition portion between the support arm and the torsion portion describes a lying on a horizontal surface tension clamp upward arc, which comprises an angular range of 80 ° - 110 °.
  • the support arm in side view in the region of this section on a bow or dome-shaped shape is ensured by the fact that the support arm even under high resilient hold-down forces or in the case of a transverse displacement of the rail Maintains shape essentially unchanged. As a result, its end portion in the tensioned state at any time is optimally linear on the rail.
  • the concentration of the generation of the hold-down force on the torsion portion can be further assisted by including the center portion with the torsion portion at an angle of 80 ° -110 ° when viewed in plan.
  • the central portion acts essentially exclusively as a lever for the torsion of the torsion without being resilient itself.
  • Tensioning clamps according to the invention can, like the tensioning clamps known from the prior art, be manufactured in one piece from a spring steel wire by forming a curved curve bent without a jump.
  • the storage and handling of a tensioning clamp according to the invention can be simplified in a conventional manner in that the distance between the free end of the angled end portion to the central portion is smaller than the smallest thickness of the central portion, Torsionsabitess, transition section, holding arms and end portion. In this way, it can be safely prevented that loosely clamped clamps interlock with each other.
  • a tensioning clamp according to the invention as the known tensioning clamps may be formed mirror-symmetrical by the central portion is formed loop-shaped and depart from it two oppositely oriented Torsionsabitese, to each of which a transition portion a holding arm is connected with an angled end portion.
  • the tension clamp according to the invention then has a W or ⁇ -shaped configuration.
  • the present invention sought concentration of the generation of the resilient hold-down force on the Torsionsabites allows a particularly space-saving design of a tension clamp according to the invention.
  • the length of the Torsionsarms is in each case so short dimensioned that the respective support arm is guided at least in sections above the guide plate.
  • the end portion of the support arm is angled relative to the adjoining him portion of the support arm that the imaginary extension of the end portion in mounting position with the web of the rail forms an acute angle of less than 90 °.
  • End sections shaped in this way can be produced particularly economically by conventional bending methods on the machines available in practice.
