Definitions

  • the present invention relates to a rail fastening which can be preassembled on concrete sleepers or the like, which is arranged on both sides of the rail at the rail fastening point and each has an elastic clamping spring and an angular guide plate, the guide plate having a side on the rail foot and on the side facing away from the rail with an inclined surface bears against a corresponding support surface of a recess in the concrete sleeper or the like and the guide plate and the clamping spring are held in their preassembly position by means of a fastening means which can be anchored in the concrete sleeper or the like and presses the clamping spring in the final assembly position onto the rail foot.
  • Such a rail fastening is known from DE-OS 39 18 091.
  • Threshold screws are used as fasteners, which are screwed into corresponding holes in the concrete sleepers using plastic dowels.
  • the clamping springs held by the sleeper screws are specially designed tension clamps made of steel bars, which are preassembled on the concrete sleepers together with angle guide plates.
  • the tension clamps are moved out of the pre-assembly position towards the rail until they engage on the side facing away from the rail in a guide groove formed in the angle guide plate and press their free ends onto the rail foot. In this position, disassembly is carried out by tightening the sleeper screws using a screwing machine until a desired clamping force is reached, the middle part of the clamping clamp coming to lie at a short distance above the rail foot.
  • This known rail fastening is characterized by a simple pre-assembly and a simple transition from the pre-assembly into the final assembly position after the rail has been inserted.
  • the angle guide plates ensure that horizontal forces are transmitted directly to the concrete sleepers and thus only pure tensile forces act on the sleeper screws so that they cannot loosen themselves.
  • Screwless rail fastening systems require special anchoring in the sleepers.
  • Systems are known in which springs are threaded, for example, parallel to the rail or perpendicular to the rail.
  • springs are threaded, for example, parallel to the rail or perpendicular to the rail.
  • one spring end is inserted into an opening in order to subsequently insert the second spring end into a second semi-open holder by means of a lever.
  • the present invention has for its object to improve a rail fastening of the type mentioned so that this in addition to the advantages of the screwed rail fastening systems, such as the direct Derivation of horizontal forces in the concrete body, an even faster and easier rail assembly enables.
  • the fastening means is a lockable anchor element which is provided with a cam plate which causes the clamping spring to be tensioned when the anchor element is rotated.
  • the solution according to the invention represents a kind of quick-release fastener which ensures an almost foolproof rail assembly. By maintaining the known angular guide plate, it is in turn ensured that only tensile forces but no shear forces act on the anchor element.
  • Clamping springs can e.g. Clamps, so-called fast clips or the like are used.
  • a preferred embodiment of the rail fastening according to the invention is characterized in that the cam disc is step-shaped and has at least one ramp-shaped section over which the clamping spring is tensioned when the anchor element is rotated.
  • the cam disc is step-shaped and has at least one ramp-shaped section over which the clamping spring is tensioned when the anchor element is rotated.
  • one or more locking steps can be formed in the cam plate, to which different degrees of tension of the clamping spring are assigned.
  • the cam disc has a first rising ramp-shaped section which merges into a first latching step, which is followed by a second ramp-like section which rises again and merges into a second latching step, the first latching step being a pre-assembly position and the second locking step corresponds to a final assembly position.
  • the ramp-shaped sections can have different slopes, the slope of the first section preferably being greater than that of the second section. In this way, the torque increase during tensioning of the clamping spring can be reduced, so that the twisting of the anchor element into the final assembly position is correspondingly facilitated.
  • Anchoring is simple and inexpensive to implement if the anchor element engages with an angled end section on the cam disk. Alternatively, however, several anchor claws can also be formed on the anchor element.
  • the anchor element can have a standard rail screw head.
  • the head of the anchor element is designed in such a way that only a special wrench, but not a commercially available wrench, can be attached to it. In this way, loosening of the anchorage by unauthorized persons is prevented or at least made more difficult.
  • the anchor element can have an internal key attachment and / or can be provided with an opening or holding part for attaching a crossbar.
  • the cam disc is held in a housing arranged in the concrete sleeper, which preferably consists of plastic.
  • the housing serves as a placeholder and the electrical track insulation, provided it is made of plastic or another electrically insulating material is made.
  • the cam disc can also be made of plastic and / or the anchor element can be encapsulated or coated with a plastic jacket. Furthermore, the anchor element can also be arranged in a sleeve made of plastic or another electrically insulating material.
  • the rail fastening according to the invention is shown on the left half of the picture in the final assembly position and on the right half of the picture in the preassembly position, specifically in FIG. 1 in a central longitudinal section through a concrete sleeper 1 and in FIG. 2 in a plan view , however, the concrete sleeper is omitted and the rail 2 is cut off outside the epsilon-shaped clamping springs 3.
  • the left side shows the outside of the track and the right side shows the inside of the track, with the rail 2 in the outside of the track in the assembled state and in the inside of the track in the pre-assembled state.
  • the rail 2 which is shown here using the example of the known rail profile UIC 60, lies on the concrete sleeper 1 between two angular guide plates 5 using a vibration-damping intermediate layer 4, the rail axis in a known manner a fixed ratio of e.g. 1:40 is inclined towards the vertical towards the track interior.
  • the angular guide plates 5 each have a longitudinal rib 6 with which they rest on the rail base 7.
  • the guide plates 5 also each have an inclined surface 8 with which they bear on the side facing away from the rail 2 against a corresponding support surface 9 of a recess 10 in the concrete sleeper 1.
  • the inner legs 11 of the clamping spring 3 are guided along the inner guide grooves 14 of the guide plate 5.
  • Rod-shaped anchor elements 15 serve as fastening means, each having a head 16 holding the clamping spring 3 and an angled end 17 which engages a cam disk 18 mounted within the concrete sleeper 1.
  • the cams 18 are each inserted in a plastic housing 19, with which they are cast in the concrete mass in the manufacture of the concrete sleeper 1.
  • the housing 19 can be oriented obliquely so that the central axis of the anchor element 15 inserted therein intersects the rail axis below the rail (see. Fig. 1).
  • the housing 19 is composed of two parts 20, 21, which can be positively connected to one another with a slight clamp fit by means of a tongue and groove connection 22 (cf. FIGS. 14 and 15).
  • the housing 19 forms a chamber-like section 23 which has a rectangular cross section.
  • the cam 18 is accordingly provided with a substantially rectangular-shaped shoulder 24, as can be seen particularly well in FIG. 9.
  • the shoulder 24 is held in the upper region of the chamber-like housing section 23 by four support ribs 25 lying in one plane, so that the cam plate 18 is fixed in the axial direction of the anchor element 15.
  • a tubular housing section 26 adjoins the chamber-shaped section 23 in the direction of the upper side of the threshold, which has a keyhole-shaped cross section with a round and a substantially rectangular partial area 27 or 28.
  • the rectangular partial area 28 is chamfered on the upper side, so that the housing 19 is arranged in the concrete just below the respective recess 10 for the angle guide plate 5 can be.
  • the housing 19 is provided with an opening 29, which meets a recess 30 in the underside of the threshold (cf. FIG. 1).
  • the angled end section 17 of the anchor element 15 can be inserted from the top of the concrete sleeper 1 through an elongated hole-like opening 31 within the guide plate 5 via the channel-shaped section 26 into the chamber-like housing section 23.
  • the cam plate 18 has a U-shaped opening 32 which meets the channel-shaped housing section 26, so that the angled end 17 of the anchor element 15 can easily pass the cam plate 18 and engage it on the underside.
  • the cam disc 18 has a first ramp-shaped section 33 with a relatively large slope, which merges into a first trough-shaped latching step 34.
  • This first latching step 34 is followed by a second ramp-shaped section 35, which has a smaller slope and merges into a second trough-shaped latching step 36 (cf. FIGS. 9 to 11).
  • the first locking step 34 serves to lock the anchor element 15 in the preassembly position.
  • the epsilon-shaped clamping springs 3 are pushed towards the rail 2 from the preassembly position, so that their free leg ends 12 press on the rail foot 7 and the Leg 2 facing away from leg 37 engage in the longitudinal groove 38 of the guide plate 5.
  • the angled end section 17 of the anchor element 15 is then removed from the first latching step 34 rotated via the second ramp-shaped section 35 into the second latching step 36 and finally locked there again.
  • the middle part 39 of the clamping spring 3 which wraps around the shaft of the anchor element 15 comes to lie at a slight distance above the rail foot 7. In this way, the rail 1 is pressed onto the concrete sleeper 1 with a certain tension (cf. right and left half of Fig. 1).
  • the rod-shaped anchor element 15 can preferably have a specially designed head 40 instead of a railroad sleeper screw head 16.
  • An example of such a special anchor element 15 ' is shown in FIGS. 4 and 5.
  • the head 40 of this anchor element 15 ' has three polygonal attachment surfaces 41 offset by approximately 120 ° for a correspondingly designed special key.
  • At the top of the head 40 there is also a bore 42 into which a guide pin provided on the special key (not shown) can be inserted.
