Definitions

  • the invention relates to a fastening of a Y-shaped steel sleeper according to the Preamble of claim 1.
  • a Y-shaped steel sleeper according to the Preamble of claim 1.
  • it is for Y sleepers on a solid road required that the sleepers be fastened to the substrate in order to to transfer the forces transmitted by the vehicle safely into the ground without that there is a shift in the track grate.
  • the invention has for its object a fastening for Y-shaped steel sleepers to develop on a solid carriageway that is aligning the track even after a long period of inactivity.
  • the fixed Roadway can be finished without any fasteners Must be taken into account.
  • a Y-shaped steel sleeper consists of several over Bolt 1 interconnected double T-shaped steel profiles.
  • Rail fasteners rails 3 are connected to the steel sleeper, so that a solid track grate forms.
  • this subsoil 5 consists of concrete or asphalt.
  • Ballast bed can be connected to the ground by incorporating the Thresholds can be reached in the gravel.
  • the foot flange 4 is the Profiles 2 of the Y-shaped steel sleeper lay flat on the base 5.
  • the fixation with the underground takes place via a firmly connected to the underground 5 Anchor 6.
  • Anchor 6 In the exemplary embodiment shown there is a bore 7 in the underground brought in.
  • the anchor 6 is then via a dowel 8 with the base 5 connected.
  • the upper end 9 of the armature 6 protruding from the underground has a thread 10, which in cooperation with a nut for bracing 11 the threshold with the underground 5 is used.
  • the clamping plate 13 can be resiliently pretensioned on the base 5. Thereby is achieved that it is flat on the outwardly tapering foot flange 4 hangs up. 2, the tensioning plate 13 is in a position that is not or only slightly tensioned shown.
  • the Y-shaped steel sleepers are insulated from the ground should be formed, can be between the clamping plate 13 and those of them spanned foot flanges 4 a plate 14 made of electrically insulating material to be ordered.
  • This plate is preferably made of plastic and also serves to prevent wear between the clamping plate 13 and the base flange 4, which can occur due to vibrations and small movements.
  • every threshold required is not the attachment according to the invention every threshold required. However, it may also be that several fastenings on a threshold are required. It can also make sense to fix this not to be arranged in place, as shown in Fig. 1.
  • Fig. 1 are more preferred positions 15 for the attachment of a fastening according to the invention marked.
  • the main advantage of the attachment according to the invention between the track grate and surface 5 is easy to align even after a long time Lay time. To do this, only the nut 11 has to be loosened. After that it is Alignment possible. Sabotaging devices regarding this loosening of the mother 11 on the thread 10 of the armature 6 are by means of measures of a professional nature provide and are not described in detail.
  • the anchor 6 can be made as long be that it runs through the asphalt layer into the one below Concrete stretches and is fastened here. If rail side forces occur it results from the permanent plasticity of the asphalt that the anchor is a receives large bending lengths, so that the rail position is no longer guaranteed becomes. According to the invention, measures are provided for this case which are supported allow the anchor 6 on the surface 16 of the substrate 5.
  • Fig. 4 shows an alternative to using the fastening according to the invention Asphalt superstructure.
  • the surface 16 is made of an asphalt mixture existing base 5 introduced a platen 18, the extends below the base flanges 4 of the profiles 2.
  • This platen 18th can, depending on the requirements of manufacture before or after the manufacture of the Asphalt layer can be connected to the anchor 6 by welding. But also without a welded connection, the use of a support plate 18 provides relief anchor 6.
  • the threshold is approximately in the middle Clamping plate 13 arranged, which is welded to the foot flanges 4 of the steel sleepers is.
  • This clamping plate 13 has a larger circular opening centrally 19 on.
  • the armature 6 consists of a base part 20, a collar 21 and Anchor elements 22.
  • the base part 20 lies in the opening 19 of the clamping plate 13 and is completed at the top by the collar 21, which is on the surface of the Clamping plate 13 rests.
  • the anchor elements 22 protrude into a recess 23 of the 5. They are formed with a head 24 at their free end.
  • the armature 6 can be provided with a pouring opening 28 through which the casting compound 25 is introduced. After the casting compound has been introduced and / or hardened the pouring opening 28 can then be closed. However, it is also possible to bring the potting compound 25 so high that it also the pouring opening fills out.
  • the clamping plate 13 is so with the profiles 2 of the thresholds connected that its lower edge is flush with the lower edge of the sleepers. It is however, it is also possible for the clamping plate 13 to overlap the foot flanges 4 of the profiles 2 and is correspondingly higher. Other forms of opening 19 and Recess 23 are conceivable.
