Definitions

  • the present invention relates to a rail storage device for sound-absorbing storage and fastening of a rail, with a ribbed plate for arranging the rail on an upper side of the ribbed plate, a first damping means and a frame.
  • the first damping means can be designed as an elastomer bearing and is arranged between the ribbed plate and the frame for damping the ribbed plate.
  • Cologne Egg refers to a rail fastening that reduces structure-borne noise. Structure-borne noise, in turn, is the cause of secondary airborne noise in buildings next to or above railway lines.
  • the name "Cologne Egg” is derived both from the oval shape of the rail support system used in practice and from the city name C perfume, since this type of fastening was first developed and used in C perfume.
  • Both the rib plate and the frame can be made of metal, these two metal parts being connected to one another by vulcanization, namely through or via the first damping means.
  • Tabs with holes can be provided on the frame for fastening to the surface using sleeper screws or threaded pieces.
  • the rib plate can be supported by the first damping means, which can preferably be designed as a vulcanized elastomer.
  • the first damping means can in turn be supported on the frame.
  • Such a structure of the rail storage device causes vertical forces to be divided into thrust-pressure components. The acoustic effectiveness of the so-called “Cologne Egg” is based on this.
  • the construction of the rail storage device of the “Cologne Egg” type known from practice has a maximum construction height of at least approximately 76 mm.
  • the construction height is understood to be the distance from the underside of the frame to the top of the ribbed plate, whereby the ribs or the height of the ribs of the ribbed plate are not taken into account when determining the construction height. Since it is also known from practice that the top of the ribbed plate runs obliquely to the ground and/or obliquely to the underside of the frame, the maximum installation height is understood to mean the installation height at the highest point on the top of the ribbed plate.
  • the object of the present invention is to avoid the aforementioned disadvantages of the prior art or at least to substantially reduce them.
  • a rail storage device for sound-absorbing storage and fastening of a rail according to claim 1.

  • the rail support device comprises a frame, which delimits the rail support device in particular on the outside.
  • the first damping means is between the ribbed plate and the frame.
  • the first damping means separates the ribbed plate from the frame, preferably completely and/or circumferentially.
  • a further damping means is provided below the ribbed plate to limit deflection.
  • the further damping means can be provided and provided separately from the first damping means. However, in further embodiments according to the invention it is also possible for the further damping means to be connected to the first damping means.
  • the additional damping means is designed in particular in such a way that a deflection limitation can be ensured.
  • the suspension or damping of the "Cologne Egg" is only provided by the first damping means. Due to the arrangement and design of the first damping means in the prior art, a certain height and width of the first damping means must be provided so that the damping properties required to reduce structure-borne noise can be guaranteed. According to the invention, it is now possible for not only the first damping means to be provided to reduce structure-borne noise and to limit deflection. The additional damping means can then also contribute to the damping properties or at least partially ensure them as well.

  • the invention provides the essential advantage that the installation height can be significantly reduced compared to rail bearing devices of the "Cologne Egg” system known from the prior art, preferably by at least 10%.
  • Such a reduction in the installation height also has the advantage that it is possible to use rail storage facilities according to the "Cologne Egg” system. also in sections and/or areas that require a construction height of less than 76 mm due to the or an existing rail support system. Accordingly, complex processing of the subsurface can be omitted, so that the rail support device according to the invention can be used comparatively easily in existing rail support systems.
  • This increases the flexibility of using the "Cologne Egg” and also creates the possibility of using the "Cologne Egg” in a large number of existing rail support systems, which was not possible before the invention due to the specified increased construction height of the "Cologne Egg” known from the prior art.
  • the deflection limitation ensures in particular that the ribbed plate can only be lowered to a certain height, which is understood according to the invention as deflection limitation.
  • This distance or this variable height difference of the deflection limitation can arise on the one hand due to the material properties of the first damping means and/or the further damping means and on the other hand due to a distance between the underside of the further damping means and the ground.
  • the first damping means also provides corresponding damping when the ribbed plate is loaded and thus also ensures the suspension properties.
  • the first damping means in addition to the further damping means, also contributes in particular to limiting deflection.
  • a deflection limitation in the range between 1 to 15 mm, preferably between 2 to 10 mm and in particular 4 mm +/- 1 mm, can be provided.
  • a deflection limitation enables effective and safe attenuation of structure-borne noise and thus contributes to the stability of buildings that are arranged near the rail.
  • an arbitrarily high level of suspension is not guaranteed; rather, the deflection limitation makes it possible to reduce this deflection to levels that have proven successful in practice.
