Definitions

  • the invention relates to a track body with rails arranged in pairs and transversely to sleepers, and to a device for its production, the sleepers with their end portions with the interposition of elastic documents in trough-like recesses of a rigid base are adopted.
  • Such track bodies are known and described, for example, in the following publications: Austrian patent specifications 304 598, 308 168 and 316 607; European patent application 49 879; British Patent 1,033,350. It is also known from these publications to further subdivide the rigid underlay made from in-situ concrete, the individual plate-like elements of these underlays being separated from one another by insulating layers.
  • This underlay made of concrete on site is manufactured in at least two work steps. First, the actual foundation plate is poured, on which the track body is then placed and aligned, and in which the end sections of the sleepers are fitted with sleeper shoes in the form of open half-boxes made of elastic material (Austrian patent specification 316 607).
  • a track body is known from DE-OS 38 09 466, which consists of rails screwed to precast concrete sleepers.
  • This track body is laid on support plates, which can be parts of a bridge structure, for example.
  • the cross section of the precast concrete sleepers is trapezoidal and tapers upwards.
  • the sleepers are not directly on the support plates on, rather they are glued to the support plate by a casting compound based on bitumen or plastic.
  • Edge boundaries are arranged along the track body and at a distance from it. Both the sleeper compartments as well as the areas between the front sides of the sleepers and the mentioned edge boundaries are filled with an asphalt mastic or with mastic asphalt, the surface of this sealing compound being only slightly below the upper edge of the sleepers.
  • a track body with such a structure is not very expedient, since repair and revision work, which is usually unavoidable at frequent intervals in the case of a busy track body, can only be carried out with extraordinary effort. Since all sleepers are practically cast in, the entire casting compound must first be removed over a long distance in such work so that the track body can be raised at all for such repair work and revision work. That should also be the reason why a track body with such a structure has so far not found a way into practice.
  • SU-PS 1 131 954 which describes a track body with sleepers, on one side of which a wedge bevel is formed, so that the cross section through the sleeper is approximately trapezoidal in this area.
  • These end sections of the threshold lie in a concrete body with corresponding recesses for receiving these sections.
  • elastic insert plates are provided, on which these threshold sections should rest.
  • a construction of this kind is not expedient, since it requires a double fit, which probably cannot be achieved with a concrete body manufactured on site.
  • the threshold with its molded-on side wedge slope either hangs in this recess in the concrete body and does not rest on the elastic intermediate layer, so that this elastic intermediate layer cannot perform the function intended for it, or it lies on the elastic one Intermediate layer on, but then the wedge bevel has play with respect to the cheek of the recess and the threshold is therefore not sufficiently securely and firmly held in this recess.
  • the invention aims at a track body of the type mentioned not only to be soundproofed, but also to anchor it on its base in such a way that the means used for its anchoring, despite the high mechanical vibration stress to which such a track body is subjected, maintain their position safely and reliably.
  • the invention proposes those measures that are the content and subject of claim 1.
  • a device serving this purpose has those features that are the content and subject of claim 9.
  • the base plate 1 and 2 has a base plate 1 made on site and running along the route, which is cast from concrete.
  • the rails 2 are fastened to sleepers 3, which are also made of concrete.
  • the fastening means provided for this purpose are not shown for the sake of clarity.
  • the end sections of the sleepers 3 lie in trough-like recesses 4 of a concrete body 5, which is also cast on site, plate-shaped elastic intermediate layers 7 being arranged between the underside of the end sections of the sleepers 3 and the bottom 6 of the trough-like recesses 4.
  • these elastic intermediate layers 7 can consist of several parts 7 'and 7' 'of different elasticity.
  • the bottom 6 of the trough-like recess 4 has a channel 8 surrounding the intermediate layer 7 (FIG. 2), which has a slope towards the center of the track body 2.
  • the length and width of the trough-like recess 4 is dimensioned such that it encloses the end section of each threshold at a distance. Since considerable forces act on the track body during operational use both in the longitudinal direction and transversely thereto (braking and acceleration forces), the end sections of the sleeper 3 are fixed by wedges 9.
  • wedges 9 are arranged in pairs on both sides of the respective end section of a threshold. It should be noted at this point that such wedges can also be arranged on the front end at the end sections of the threshold 3, and everything that is said in the following about the wedges shown in FIG. 1 also applies in an analogous manner to those wedges which are to be attached at the front to the end sections of the sleepers 3.
  • Such a wedge is shown in an oblique view in FIG. 3. Its back 10 is profiled and has a plurality of horizontally running steps 11.
  • the wedge is made in two parts. over its strength is in areas 13 and 14 of different elasticity.
  • the area 13 of the wedge 9 provided for contacting the wall 17 of the trough-like recess 4 is made of a hard
  • the area 14 provided for contacting the threshold 3 is made of a soft plastic material.
  • bores 16 are provided in pairs on both sides, to which a lever-like tool can be attached in order to lift the wedge out of its operational position.
  • the width 12 of the wedge 9 is smaller than the length of the end section of the threshold 3 and is approximately half or less of the same.
  • the profiling on the back 10 of the wedge 9 interacts with a corresponding profiling on the wall 17 of the trough-like recess 4 and thereby secures the seat of the driven wedge 9.
  • Fig. 4 now illustrates a U-shaped molded part 18, the axial extent 19 corresponds approximately to the height of the end portion of the threshold 3 and the cheek height 20 of the length of the trough-like recess 4.
  • the molded part is expediently made of plastic.
  • the inner cross-sectional profile of the shaped piece 18, viewed in the direction of its height 20, is approximately corresponding to the cross-sectional profile of the end section of the threshold 3.
  • Such an assembly aid can be designed as a bracket that engages over the molded part 18.
  • Insert plates 24 are arranged on the outside of the cheeks 22, the outside of which are correspondingly designed for profiling the rear side 10 of the wedges 9.
  • the insert plate 24 (FIG. 5) lies flat against the cheeks 22 of the molded part 18.
  • the insert plate 24 protrudes above the molded part 18 and is with its outstanding Section releasably connected to the molded part.
  • Shafts can be arranged on the upper edge of the molded part, which carry bores through which horizontally lying fastening screws can be threaded.
  • the insert plates 24 are arranged in vertically extending groove-like recesses 25 in the cheeks 22 of the molded part 19 and are guided through these undercut recesses 25.
  • Spreading wedges 26 secure and fix their position.
  • the width of these insert plates 24 corresponds approximately to the width 12 of the wedges 9 or is somewhat larger than this.
  • the track body of the type shown in FIGS. 1 and 2 is now erected as follows: After the foundation plate 1 has been poured along the track route, the track grating assembled from the rails 2 and the sleepers 3 is placed and opposite the foundation plate 1 with length-adjustable spindles supported, aligned and leveled. At the end sections of the sleepers 3, the elastic intermediate layers 7 are already attached, preferably glued, at the factory. If the track grate is aligned and leveled in the manner described, a formwork is built parallel to and below the rails 3 for the concrete body 5 to be cast on site.
  • the assembly aids for the molded parts 18 are removed, the fasteners between the molded part 18 and the insert plate 24 or the expansion wedge 26 are pulled out, and then the molded parts and then the insert plates 24 can be pulled out and removed and used again on a subsequent track section .
  • the wedges 9 are then inserted and driven in. 1 and 2 show a track body erected in this way. During revision work on the track body, the wedges 9 are first pulled out. For this purpose, a lever-like tool, not shown here, is used, which is attached to the bores 16 of the wedges 9 and with which the wedges 9 are lifted out of their anchoring given by the profiling and then pulled out.
  • the track grate consisting of the rails 2 and the sleepers 3 can be lifted up by means of threaded spindles or other lifting tools, so that, inter alia, the underside of the end sections of the sleepers 3 can be accessed, so that the elastic, possibly multi-part intermediate layer can be replaced .
  • the wedge 9 is narrower than the length of the recess 4. It is conceivable to make the wedge 9 as long as the recess 4.
