Definitions

  • the invention relates to an attachment of a Y-shaped steel sleeper according to the preamble of claim 1.
  • an attachment of the sleepers with the Underground is used to safely guide the forces transmitted from the vehicle into the underground without the track grating being displaced.
  • DE 35 17 295 A1 discloses a fastening for a Y-shaped steel sleeper with the solid base, in which anchors connected to the base are used.
  • This training has the disadvantage that it is very complex and the completion of the solid track is extremely difficult, since the anchors must already be used in the manufacture of the fixed track.
  • a further disadvantage is that alignment of the track is not possible either during initial laying or when working through it. This orientation is moved into the rail fastening, which complicates the rail fastening.
  • the invention has for its object to develop a fastening for Y-shaped steel sleepers on a solid carriageway, which enables alignment of the track even after a long period of inactivity.
  • the solid track can be made ready without having to consider any fasteners.
  • a Y-shaped steel sleeper consists of a plurality of double-T-shaped steel profiles which are connected to one another by bolts 1.
  • Rails 3 are connected to the steel sleeper via rail fastenings, not shown, so that a solid track grating is formed.
  • this subsoil 5 is made of concrete or asphalt.
  • the foot flange 4 of the profiles 2 of the Y-shaped steel sleeper lies flat on the base 5.
  • the fixation to the substrate takes place via an anchor 6 which is firmly connected to the substrate 5.
  • a bore 7 is made in the substrate.
  • the anchor 6 is then connected to the base 5 via a dowel 8.
  • the upper end 9 of the armature 6 protruding from the underground has a thread 10 which, in cooperation with a nut, serves to brace 11 the threshold with the underground 5.
  • the clamping plate 13 can be resiliently biased to rest on the base 5. This ensures that it lies flat on the outwardly tapering foot flange 4. 2, the tensioning plate 13 is shown in a position that is not or only slightly tensioned. If the Y-shaped steel sleepers are to be designed to be insulated from the subsurface, a plate 14 made of electrically insulating material can be arranged between the tensioning plate 13 and the foot flanges 4 spanned by them.
  • 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 minute movements.
  • the attachment according to the invention is not included every threshold required. However, it may also be necessary to have several fastenings on one threshold. It can also make sense not to arrange this fastening in place, as shown in FIG. 1. In Fig. 1 further preferred positions 15 are marked for the attachment of a fastening according to the invention.
  • the main advantage of the fastening according to the invention between the track grate and the base 5 is the simple alignment even after a long period of inactivity. To do this, only the nut 11 has to be loosened. Alignment is then possible. Sabotaging devices regarding this loosening of the mother 11 on the thread 10 of the armature 6 are to be provided by means of measures of a professional nature and are not described in more detail.
  • the anchor 6 can be made so long that it extends through the asphalt layer into the underlying concrete and is fastened here.
  • the permanent plasticity of the asphalt can result in the anchor being given a large bending length, so that the rail position is no longer guaranteed.
  • measures are provided for this case which allow the armature 6 to be supported on the surface 16 of the substrate 5.
  • Fig. 4 shows an alternative to using the fastening according to the invention on asphalt superstructure.
  • a support plate 18 is introduced into the surface 16 of the base 5 consisting of an asphalt mixture, which extends to below the foot flanges 4 of the profiles 2.
  • this support plate 18 can be connected to the anchor 6 by welding before or after the production of the asphalt layer.
  • the use of a support plate 18 relieves the load on the armature 6.
  • a tensioning plate 13 is arranged approximately in the middle of the threshold, which is welded to the foot flanges 4 of the steel sleepers.
  • This clamping plate 13 has a larger circular opening 19 in the center.
  • 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 tensioning plate 13 and is closed at the top by the collar 21, which rests on the surface of the clamping plate 13.
  • the anchor elements 22 protrude into a recess 23 of the base 5. They are formed with a head 24 at their free end.
  • the surface of the substrate 5 has not yet been processed. Only after alignment with regard to position and height is a drilling device placed on the tensioning plate 13.
  • the drill corresponds to the opening 19, is guided in this opening 19 and drills a hole 23, which in the embodiment is hole-shaped, into the base 5.
  • the anchor 6 with its anchor elements 22 is then inserted through the opening 19 of the tensioning plate 13 into the recess 23 of the base 5 and connected to the substrate by introducing a casting compound 25 into the recess 23.
  • the armature 6 can be screwed to the tensioning plate 13 before or after.
  • 13 bolts 26 are welded to the tensioning plate, which protrude through holes in the collar 21. Nuts 27 then serve for connection.
  • 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 introduce the casting compound 25 so high that it also fills the pouring opening.
  • the clamping plate 13 is connected to the profiles 2 of the sleepers that its lower edge is flush with the lower edge of the sleepers. However, it is also possible that the clamping plate 13 overlaps the foot flanges 4 of the profiles 2 and is correspondingly higher. Other shapes of the opening 19 and the recess 23 are also conceivable.
