Definitions

  • the present invention relates to a collar tie screw for fastening a rail base on a reinforced concrete support plate and / or reinforced concrete tie.
  • ballast-free superstructure is increasingly being used for high-speed railways, trams and subways, in which the track systems are laid on concrete foundations (concrete slabs, longitudinal concrete beams, concrete sleepers).
  • This ballastless superstructure offers the advantage of a low-maintenance road with high availability.
  • ballastless superstructure with its low-maintenance or maintenance-free route with high availability are undisputed.
  • the present invention has therefore set itself the task of providing a generally usable collar sleeper screw, which is used to fasten the rail support points and is not destroyed by the occurrence of the dynamic stress, but rather absorbs this dynamic stress by shock-absorbing springback.
  • the loads on the train journey are to be absorbed and the reaction forces from the deflection process are to be compensated equally.
  • a collar sleeper screw with a sleeper screw thread at the lower end a central part which is cylindrical or oval and has no thread, an upper part which is cylindrical and has a machine thread, an upper tip which acts as a polygonal head or polygonal imbus is configured, an optionally eccentrically designed plastic collar bushing fitting around the central cylindrical or oval part of the screw, a spiral spring fitting around the cylindrical part of the screw and a stop nut fitting on the machine thread.
  • the sleeper screw thread preferably corresponds to the standard of European railways, but differently dimensioned sleeper screw threads can also be used.
  • the metric thread also preferably corresponds to the standard of the European railways, but other thread designs can also be used here, for example metric and inch threads.
  • the plastic collar bushing can also be designed eccentrically, so that a change in position of the rail support can be brought about by turning.
  • the socket is from one - 4 -
  • the upper tip of the collar tie screw is preferably designed as a hexagon head, but can also be configured as a hexagon headbus.
  • Polygonal heads and polygonal bus tips, for example square heads or square bus tips are possible in principle, but less suitable for practical use and the standard tools available there.
  • the spiral spring is preferably ground at right angles on its top and bottom, so that a full-surface support on the socket on the one hand and the stop nut on the other hand is ensured.
  • the coil spring has the task of applying a defined contact pressure from the collar tie screw via the coil spring and bush to a rail support part to be fastened.
  • the coil spring should never be “clamped” so that it can cushion the dynamic stress during operation.
  • the required and definable contact pressure is applied to the rail support point via the stop nut and the defined spring tension of the spiral spring. Any height adjustment to be carried out on the rail support can be carried out using a longer or shorter spiral spring, without the collar tie screw having to be changed. It is only important to ensure that the contact pressure to be defined is set correctly.
  • the spring is guided over the cylindrical part of the collar sleeper screw without damaging the thread in the upper part of the collar sleeper screw.
  • the coil spring is 5 -
  • the stop nut which has the task of ensuring a defined contact pressure on the coil spring and thus on the collar bushing, is designed in such a way that it cannot come loose by itself. This is preferably done by an inserted plastic ring in the upper part, which is smaller in diameter than the machine thread in the upper part of the collar tie screw. When the nut is screwed onto the collar tie screw, the plastic ring presses into the thread without damaging it. An automatic loosening of the stop nut is not possible even with dynamic loads.
  • stop nut can also be cranked in the upper area and thereby prevented from loosening independently.
  • this configuration has the disadvantage that the threaded part on the collar tie screw is damaged or even destroyed, and thus reuse is no longer possible.
  • the collar tie screw is connected to the substrate by screwing it into a correspondingly prefabricated borehole and / or a corresponding dowel made of plastic or similar suitable materials with synchronous thread or shaft diameters.
  • the new collar sleeper screw is therefore universally applicable and can therefore easily replace types of collar sleeper screws previously used.
  • Figure 1 shows the individual parts in a side view.
  • Figure 2 shows the same parts in an oblique side view.
  • Figure 3 shows the collar tie screw in the installed state. n figures means each
  • the threshold screw thread The middle part, which is cylindrical or oval and has no thread.
  • the upper part which is cylindrical and has a machine thread.
  • An upper tip which is designed as a hexagon.
  • a spiral spring and the stop nut that fits on the machine thread.
