Definitions

  • the invention relates to a system for fastening a rail, said system comprising a braced against a substrate by means of a clamping element spring member having at least one spring arm, and an adapter piece having a receptacle in which an end portion of the spring arm of the spring element sits.
  • the invention relates to an adapter piece provided for such a system.
  • An adapter piece used in a system according to the invention has a contact surface section formed on its circumference, with which it sits on the rail foot of the rail to be fastened when the system is completely assembled, in order to transmit the elastic hold-down force caused by the spring element to the rail foot.
  • the adapter piece isolates the tension clamp used there as a spring element with respect to the rail.
  • This is the adapter piece of an electric non-conductive material.
  • the adapter piece in the known system has a receptacle which is adapted to the shape of the insulating clip associated end portion so that the spring portion is positively inserted into it. The relevant end portion of the spring element can thus be inserted into the receptacle so that at least a portion of its circumference is surrounded by material of the adapter piece.
  • the known adapter piece has a contact surface extending below the receptacle.
  • This contact surface ensures that the adapter piece is guided at all times so that the end portion of the spring element engaging in its respective receptacle always remains in the relevant receptacle. In this way, the adapter piece can be easily postponed from a preassembled on the guide plate of the known system position on the rail without requiring a manual intervention of a technician or special measures by an assembly machine are required.
  • the object of the invention to provide a system for fixing a rail, in which differences in hold-down force, which can be adjusted due to structural inaccuracies of the ground or required becoming adjustments to the altitude of the rail, can be compensated in a simple manner. Similarly, a simple, inexpensive means should be given, with which such compensation is easily possible.
  • the adapter piece used in the prior art as an insulator assumes the function of a compensating element, with which the forces applied by the respective spring element to the foot of the rail to be fastened can be adjusted.
  • the invention provides for rotatably supporting the adapter piece at the end portion of the spring arm of the spring element about an axis of rotation and at the same time provide at the periphery of the adapter piece at least two contact surface portions of which depending on the respective rotational position of the adapter piece each one bears against the rail.
  • the one contact surface portion of the adapter piece has a greater distance from the axis of rotation of the adapter piece than the other contact surface portion.
  • the adapter piece is formed and arranged on the spring arm of the spring element of a system according to the invention that it can be adjusted in the manner of an eccentric to the force applied in terms of the tension of the spring element and the spring element force substantially distance between the free end of the spring element and Adjust the surface of the rail foot. So can the distance and, consequently, the spring element to increase the holding force exerted on the rail by the fact that the adapter piece is supported by the contact surface portion on the rail foot, which has a large distance to the respective free end of the spring arm of the spring element. Accordingly, the effective hold-down force can be reduced by rotating the adapter piece so that it is supported on the rail foot by a contact surface portion arranged at a smaller distance from the free end of the associated spring arm.
  • An adapter piece intended for a system according to the invention for fastening a rail which has a receptacle in which an end portion of a spring element is insertable, is accordingly characterized in that it has at its periphery at least two abutment surface portions, each of which is provided depending on the assembly position of the adapter piece to lie on a rail of each rail to be fastened, and each of which has a distance from the central axis of the receptacle, which differs from the distance of the respective other contact surface portion to the central axis of the recording.
  • an inventively designed adapter piece it is thus easily possible to accomplish a height compensation between two adjacent attachment points of the rail, for example, that the height of the rail foot above the ground or one of the other components of the respective Rail support system supporting shim to vary by means of one or more intermediate layers, wherein the respective spring element supporting the guide plate thereby stops directly on the shim or the ground.
  • the associated with the height variation of the support of the rail foot change of the spring element in the fully assembled state applied to the rail hold-down force can be compensated by a corresponding adjustment of the adapter piece also.
  • the contact surface portions of the adapter piece can have any shape, as long as in the mounting position a secure fit of the adapter on the rail and at the same time an equally secure transmission of hold-down are guaranteed.
  • This can be accomplished in a particularly simple manner by virtue of the fact that the contact surface sections are each of a planar design.
  • the planar design of the contact surface sections not only has the advantage of a secure fit and an equally secure and large-scale distribution of hold-down force on the rail, but also allows the respective contact surface section to assign a specific, unique adjustment.
  • the adapter piece is designed to be elastic in the circumferential direction and the inclusion of the adapter piece to a small undersize is smaller than the circumference of its associated end portion of the spring arm of the spring element, so that in the assembled position, the adapter piece is positively and non-positively held on the end portion of the spring arm of the spring element.
  • This embodiment allows in a simple way a captive pre-assembly of the adapter piece on the respective associated spring arm.
  • the adhesion between the adapter piece and spring arm can be dimensioned so that the adapter piece safely retains its position with respect to the spring arm associated with it when moving from a pre-to a final assembly position even under the forces occurring.
  • the correct position attachment of the adapter piece to the associated spring arm can also be supported by the fact that the receptacle of the adapter piece is designed as a blind hole opening, in the bottom of a passage opening is formed.
  • the passage opening makes it possible that moisture entering the receptacle can escape, so that the risk of the formation of corrosion or frost damage is effectively met.
  • the above-explained elasticity of the adapter piece can be achieved by forming a slot extending in the radial direction into the circumferential wall bounding the receptacle. Through this slot, the adapter piece is widened during insertion of the spring arm into the receptacle in the manner of a ring spring, so that the adapter piece is held in consequence of the then prevailing restoring forces with acting over the entire circumference of the seated in the receptacle end portion of the spring arm frictional connection.
  • the passage opening advantageously provided in the region of the bottom can be formed by the fact that the slot continues into the bottom of the receptacle.
  • the invention is suitable for any type of rail fastening, regardless of whether a spring element with one or two spring arms is used for generating the hold-down force.
  • the spring element is an ⁇ -shaped tension clamp with two spring arms and each of the spring arms is assigned an adapter piece in each case. This not only allows a particularly simple installation of the adapter pieces, but also an individual adjustment for each spring arm.
  • the adapter piece electrically isolate the spring element relative to the rail.
  • the adapter piece for example, be made of an electrically non-conductive material, in particular a plastic.
  • a guide plate which has an abutment surface on its end face assigned to the rail foot and on its free upper side a sliding surface rising in the direction of the abutment face over which the adapter piece consists of a preassembly position determined by a stop formed on the guide plate in which it sits with its respective selected contact surface portion on the guide plate, is slidable in a mounting position, in which it sits with the abutment surface portion on the rail of the rail to be fastened to the Bewi of the spring element To transfer elastic restraining force on the rail foot.
  • the spring element is also arranged on the guide plate on which are usually formed for this purpose mold elements that guide the spring element and secure its position.
  • the adapter piece in the pre-assembly position is pressed against the stop by the hold-down force exerted on it, which is exerted by the spring element coupled to the adapter piece via its respective spring arm.
  • the adapter piece In order to be pushed into the finished mounting position, the adapter piece must thus be pushed up from the stop obliquely upwardly leading sliding surface with the result that the spring forces exerted by the spring force increase and an additional force load must be overcome. Since this does not happen without intentionally introduced from the outside force, the adapter piece and with him the spring element are automatically held in the preassembly until the Fertigmontagevorgang begins.
  • a shim extending across the width of the guide plate is provided across the width of the guide plate and arranged to compensate for height differences between the guide plate and the respective substrate, the shim having a rectangular basic shape and a passage opening for clamping the spring element has inserted clamping element, and wherein the shim along a Punch line is divided into two parts, which is guided by one of the transverse to be fastened rail aligned longitudinal sides of the shim starting with distance to its one narrow side to the through hole and from there the passage opening is cut in the direction of the narrow side of the shim.

  • the other part of the shim thereby fills the cut-out portion of the first part, wherein it defines the part of the through hole of the shim, which is not bounded by the first part.
  • a first advantage of the inventive design of such a shim is that the two parts of the shim can be easily retrofitted to a mounting system according to the invention by the one part seen in the longitudinal direction of the rail from one side and the other part from the other side be pushed under the already mounted other components of the fastening system. Once the two parts of the shim are fully inserted, they tightly enclose the chucks so that, despite the split of the shim, the same extensive support is provided on the shim resting components and material layers is guaranteed as an undivided shim.
  • Another important advantage in practice of the embodiment of a shim according to the invention is that it is undivided at least in the region of its one narrow side.
