Definitions

  • the invention relates to a ballastless superstructure for rail-bound traffic with constructed and prefabricated concrete slabs to the subject, according to the preamble of claim 1.
  • ballastless superstructure There are various embodiments of a ballastless superstructure known.
  • sleepers with rails attached are embedded in concrete on the track.
  • Such a construction has the disadvantage that an extremely high Justierarbeit is required to achieve a flat and rectilinear alignment of the rails.
  • the circumstance is not sufficiently taken into account that a superstructure under load sufficient, z. B. by 2 mm to 3 mm, and at the end of the load should return to the starting position.
  • a ballastless superstructure is for example in the AT 410 329 B described. This is on a leveled substrate a concrete slab or possibly concrete bucket, if higher cornering forces are required provided.
  • a support plate is arranged, which has in its four corners Muttergewinde technicallye in which supports are screwed with threads. Through these supports can be done a precise adjustment of the support plate above the ground.
  • the support plates in turn have larger rectangular recesses, which are oriented parallel to the rail longitudinal direction. About these recesses and additional filling openings, which are passed through the support plate, a flowable mass of concrete is introduced. After hardening, the supports can be removed.
  • the concrete slab is held in its vertical position by the intermediate layer and the dead weight of the slab.
  • the position of the plate in the horizontal is due to the hardened concrete in the rectangular recesses.
  • the support plate can perform the required compression, it has on its underside a rubber-elastic layer with a release agent, eg. Wax, over which it rests on the intermediate layer of concrete.
  • ballastless superstructure for trams which has longitudinal sleepers for the rails. These longitudinal sleepers are arranged in recesses of the superstructure, which expand upwards.
  • the invention has for its object to provide a ballastless superstructure with support plates, with a safe Auflagerung the support plates can be done on the ground and a corresponding deflection is also given, a full-surface introduction of the grout is easily possible, and also the replacement of a support plate Without heavy lifting equipment is possible because there are no mechanical connections between the rubber-elastic layer and the grouting mortar.
  • the ballastless superstructure according to the invention for rail-bound transport constructed with concrete prefabricated support plates which carry at least two rails, in the rail longitudinal direction have a greater extent than normal thereto, and at least two rectangular continuous open to the ground recesses, and a rubber-elastic layer with Rubber granulate, which is bound with a rubber-elastic binder, resting on a potting compound with hydraulic and latent hydraulic binder with a substrate on a release agent, essentially consists in that the rubber-elastic layer on at least one surface, which is acted upon by the potting compound , with) a pasty release agent is leveled smooth, and the recesses are tapered upwards.
  • the potting compound can no longer penetrate into the rubber-elastic layer and cause a positive connection.
  • a flow channel for the potting compound is formed by this surface formation of the rubber-elastic layer, which may have smooth walls.
  • the potting compound is particularly easy to meet the gap between rubber-elastic layer and the substrate. If the recesses are tapered upwards, an exact positioning of the support plates on the substrate is possible on the one hand, and on the other hand a positive connection between the support plate and the grout can thus be avoided even in the recesses themselves.
  • the desired viscosity of the release agent can be set particularly easily since it is only necessary to provide a higher proportion of filler in order to increase the viscosity.
  • the rubber-elastic layer has at least two layers connected to one another via a rubber-elastic binder, it is particularly easy to achieve adaptation to specific rubber-elastic properties by the multi-layered design, then the different layers can have different rubber-elastic properties. These can be achieved by different rubber particles, different size or different binders.
  • the particles of the rubber granules have a maximum extent of 1 mm to 4 mm, in particular 2 mm to 3 mm, a particularly fine-grained structure is provided, which can be leveled easily and effectively with a pasty release agent.
  • the particles of the rubber granules have a Shore hardness of 50 to 80, a long service life under dynamic load can be achieved.
  • the deflection behavior can be controlled.
  • Fig. 1 are four support plates 1, 1a shown in concrete, from top to bottom through recesses 2, 2a and through injection ports 3 have.
  • the rail 4 with the support plates made of concrete 1 is detachably connected.
  • the support plate has an elevation 5, so that the rails are arranged elevated relative to the remaining areas of the support plate.
  • dowels 6 are provided which cooperate with screws 7, which connect the rail 4 via clamps 8, base plate 9 and a rubber-elastic intermediate plate 10 releasably connected to the support plate.
  • the support plates 1 have a dimension of 2400 mm by 5160 mm. Typical dimensions are between 2000 mm to 2700 mm by 3000 mm to 7000 mm. Your minimum thickness d ( Fig. 2 ) is between 140 mm and 250 mm, in the present case 160 mm.
  • the recesses 2 are formed rectangular, with the longer side of the rectangle is arranged parallel to the rail longitudinal direction and 900 mm, whereas the width extension is 600 mm.
  • the recesses 2a correspond to the recesses 2, but are designed to be larger parallel to the track plane and have the following dimensions 910 mm by 610 mm.
  • the support plates are, as particularly clear Fig. 2 can be seen, via a plane-parallel potting compound 12 on a substrate 13, u. zw. the floor or a concrete tub 14, on. Instead of the concrete tub, a concrete slab or only the leveled ground can be provided.
  • the support plates 1, 1 a have on their surfaces facing the potting compound 16, 17 a prefabricated rubber-elastic layer 15, the one Has thickness of 6 mm and extends beyond the outer contours of the support plate 1, 1a. This layer is covered with rubber particles 18, 19 ( Fig. 3 ) with a maximum extension of 2 mm to 3 mm, which are connected by a flexible polyurethane binder.
  • the potting compound 12 also protrudes into the upwardly tapering recesses 2, 2 a of the support plates, wherein the surfaces 17 of the recesses also have a rubber-elastic layer 15.
  • the rubber-elastic layer 15 is connected to the support plate via a rubber-elastic binder.
  • support plate 1 is, as already stated, constructed with concrete and has a minimum thickness d of 160 mm.
  • a replacement support plate, in which the dynamic loads are also taken over by the adjacent support plates, may have a minimum thickness d of 140 mm, so that when replacing the first plate without much additional expenses, another layer of potting compound in the thickness from 20 mm can be inserted , then there is a track superstructure with support plates of different thickness.
  • a rubber-elastic layer 15 which is composed of two layers 15a and 15b. In both layers, which are connected via a rubber-elastic binder, particles of a rubber granules with a Shore hardness 70 are included. Both layers have a thickness of 3 mm.
  • the layer 15a has particles 18 of rubber granules with a maximum extension of 3 mm with plastic fibers, whereas the rubber particles 19 of the layer 15b have a maximum extension of 2 mm, whereby the layers have different properties.
  • the particles 18, 19 are connected to a rubber-elastic polyurethane binder.
  • the lower surface of the rubber-elastic layer 15b is provided with a pasty release agent 20, for example a Paraffin water emulsion with 35.0 wt .-% limestone powder, fully illustrated in the drawing, leveled and therefore has a substantially smooth surface, whereas the upper surface of the elastic layer 15a has a structured by the particles of rubber granulate surface.
  • a pasty release agent 20 for example a Paraffin water emulsion with 35.0 wt .-% limestone powder
  • pasty release agents are paraffin, higher viscosity oils, and aqueous emulsions of these release agents with a filler, eg. As zinc oxide, chalk, lime.
  • a lifting force of 96 t per plate is required to take off. If a support plate of the same size lifted, the rubber-elastic layer is leveled with a pasty release agent, so only about one twentieth of the lifting force, u. between 4.2 t, required.
