Definitions

  • the invention relates to a method for producing a molded concrete body that receives the rails of a track, in particular a track sleeper or track support plate for a railroad crossing that can be passed over by rails, with an elastic layer made of an elastomer or elastic plastic attached to at least one supporting outer surface, the shaped concrete body being in a mold is produced, which is at least partially covered with an elastic insulating mat and then the concrete is poured in, so that after the concrete has set, the insulating mat is connected to the track supporting plate.
  • Concrete track slabs are used in the construction of fixed track carriageways.
  • these track support plates are supported with rubber.
  • a method for producing a rail fastening which consists of a concrete structure forming part of the substructure with cavities for receiving concrete support blocks, in which plates of elastic material are already in the concrete form during the manufacture of the concrete support blocks are attached to form the elastic layer.
  • These elastic material plates are coated on the inward-facing surface with a layer of liquid, hardenable synthetic resin, in particular epoxy resin.
  • the concrete is then poured into the mold, with the synthetic resin layer still liquid.
  • the connection between the elastic material plate and the hardening concrete is created by an additional adhesive. This considerably increases the technical complexity of the process. Furthermore, liability is not always sufficient.
  • the invention has for its object to provide a method of the type mentioned, in which the molded concrete body receiving the tracks elastic layer has good adhesion to the concrete surface and the manufacturing process requires less effort.
  • the elastic insulation board is a composite mat that consists of a layer of bonded rubber granulate with an open-pore structure and a vulcanized, water-impermeable, wear-resistant cover layer on one side and that the composite mat is laid in the concrete form so that the Cover layer lies against the mold wall.
  • the composite mat is laid in the form or formwork in the manufacture of the concrete molding so that the cover layer points towards the form wall or formwork.
  • the exposed, open-pore structure of the rubber granulate layer comes into contact with the liquid concrete.
  • the concrete diffuses into the boundary layer of the rubber granulate layer forming an insulation layer. This results in a connection between the concrete and the composite mat.
  • the composite mat remains on the molded concrete body produced when it is removed from the mold.
  • the liability is excellent.
  • the molded concrete body can be stored or stored in an elastic manner.
  • the water entering the open-pore insulation layer during the setting of the concrete is separated by the additives with a higher density, e.g. Gravel, cement and sand from the open-pore layer, pressed against the later molded concrete surface.
  • a higher density e.g. Gravel, cement and sand
  • the production of the shaped concrete body is carried out as a finished part.
  • the concrete moldings are manufactured as prefabricated segments outside the construction site in a factory and brought to the construction site.
  • the concrete moldings with the connected insulation boards can be installed immediately. They are inevitably elastic immediately.
  • the elastic insulation mats are also partially installed in the side area so that butt joints do not have to be lined separately for track supporting slabs. Another advantageous embodiment can be seen in the fact that the production of track support plates can be carried out directly at the place of use of the road construction.
  • the elastic insulation mat serves as lost formwork.
  • the rubber granulate is bonded with polyurethane.
  • a layer of compact rubber material is used as the cover layer.
  • the compact rubber material is characterized by water impermeability and wear resistance to mechanical loads.
  • FIG. 1 is a front view of a track support plate provided with an insulation mat
  • Fig. 2 is a sectional view of an insulation mat with an open-pore rubber granulate layer.
  • a track support plate 1 made of concrete has two longitudinal and parallel recesses 2 which are arranged at a distance from one another to the rails.
  • the underside 3 of the track support plate 1 and the two longitudinal sides 4 running parallel to the recesses 2 are provided with a composite mat 5 made of rubber granulate. This composite mat 5 has already been introduced into the casing during the manufacture of the track support plate 1.
  • the composite mat 5 consists of an insulation layer 8 of relatively great thickness and a cover layer 10 applied on one side, which is only provided with a relatively smaller thickness.
  • the thickness ratios of insulation layer 8 and cover layer 10 are between 7: 1 and 14: 1, but preferably between 9: 1 and 12: 1.
  • the insulation layer 8 of the composite mat 5 is made of bonded rubber particles 12, while the cover layer 10 consists of a flexible and compact rubber material.
  • the rubber particles 12 of the insulation layer 8 are formed exclusively from porous material, such as cell, moss or foam rubber chips, which should have a size or dimension between 2 and 18 mm.
  • Bound rubber granulate 12 can be used to produce the insulation layer 8, which can consist of foamed rubber material of different densities. Mixtures of regranulated rubber material can also be used.
  • the porous rubber particles 12 used to form the insulating layer 8 have favorable dynamic properties and, in particular under dynamic loading, do not behave or are only slightly stiffer than under static loading.
  • the insulating layer 8 made of rubber granules leads to particularly high internal damping. For the application of elastic support for track supporting slabs, this means a lower resonance increase in the area of the system natural frequency.
  • the open-pore structure 14 of the rubber granulate layer 8 faces inwards, i.e. to the adjacent concrete 15. The liquid concrete 15 diffuses into the open-pore structure 14 of the granulate layer 8 and firmly bonds with it in the concrete / rubber boundary layer.

Abstract

Un procédé permet de fabriquer un corps moulé en béton qui porte les rails d'un chemin de fer et dont au moins une surface extérieure porteuse est pourvue d'une couche élastique en élastomère ou en matière plastique élastique. Afin d'assurer une bonne adhérence de la couche élastique sur la surface du béton, le corps moulé en béton est produit dans un moule revêtu au moins en partie d'un mat isolant élastique (5) à pores ouverts, puis rempli de béton, de sorte qu'après la prise du béton, le mat isolant (5) est lié à la dalle (1) de support de rails.
