Definitions

  • the present invention relates to an anti-noise device.
  • the object of the invention is to produce an anti-noise device allowing to significantly reduce the vibrations induced in the ground by the passage of a rail vehicle, in particular a tram.
  • an anti-noise device is characterized in that it includes a jacket made of elastic and resistant material arranged to wrap at least one lateral flank of a rail, in particular a rail for trams. Since the jacket covers at least one side lateral, at least this side there is no longer in direct contact with the ground. The elasticity of the jacket ensures adequate absorption of force induced by the passage of the tram on the rail, as well as vibrations caused by the tram passage. The absorption of vibrations by the jacket placed against the side of the rail will cause that the vibrations will be noticeably that their transmission through the ground will be considerably scaled down.
  • a first preferred embodiment of a device according to the invention is characterized in that the jacket comprises a part arranged to be placed under the lower side of said rail.
  • the realization in parts of the jacket allows not only ease of manufacture and assembly, but also to wrap the rail over its entire part which is buried in the ground, thus minimizing the transmission of vibrations in the ground.
  • a second preferred embodiment of a device according to the invention is characterized in that the jacket has an edge upper arranged to be juxtaposed to the upper face of said rail, said edge upper having a width substantially equal to 42 mm. This dimension of the upper edge of the jacket allows to have between two rails provided with their jacket a gap corresponding to five and a half klinkers, thus facilitating filling the center of the track.
  • a third preferred embodiment of a device according to the invention is characterized in that the jacket comprises in its first and second part at least one perforation, intended for passage of the rail spacers.
  • the jacket does not interfere with the passage of the spacers.
  • a fourth preferred embodiment of a device according to the invention is characterized in that the jacket is provided with fixing means arranged to fix the parts together. This allows to fix the dust jacket to the rail before the installation of the latter and thus to install the rail provided with its jacket.
  • the jacket is made of a material having a elasticity factor between 5 NM and 20 NM measured according to the standard DIN 53515. This allows the jacket to withstand the forces which are imposed by the rolling of the tram on the rail.
  • the jacket is made of a material having a pressure resistance of at least 40 kg / cm 2 .
  • the jacket thus also resists road traffic passing on the road in which the rail is located.
  • the jacket is made of rubber, especially recycled rubber. This material has the advantage of being little expensive while having the required elasticity and strength.
  • anti-noise device for tram rails.
  • this device is not limited to tram rails but can be used for any rail, whether it is a tram, train or other rail vehicle.
  • the device finds its application especially on site urban where the rail is buried in the ground. However it could also be used for rails that are not buried.
  • the anti-noise device according to the invention is also not limited to the embodiments included in the drawings and other geometries, insofar as they fit the rail profile, are possible.
  • Figure 1 illustrates an example of an anti-noise device 1 according to the invention and mounted around a rail end 5.
  • the device has three parts 2, 3 and 4.
  • the first 2 and the second 3 part respectively envelop a first and a second lateral flank of the rail 5.
  • a third 4 part is arranged under the sole of the rail 5.
  • the anti-noise device according to the invention therefore comprises a jacket which at least partially encloses a rail.
  • the jacket has all three parts, but only one part could suffice if necessary as illustrated in figure 5.
  • the lateral flank of the rail being from the outer side of the rail, i.e. the side opposite to that of the inter-rail, could be fitted with the dust jacket.
  • the third part might be enough.
  • the jacket is made of an elastic and resistant material such as vulcanized rubber.
  • the material must be elastic because it must be able to absorb the forces induced by the vehicle traveling on the rail, as well as those induced by the traffic traveling on the roadway where the rails are buried.
  • the material must be resistant because it must be able to resist temperatures ranging from - 30 ° to + 40 ° C and keep substantially the same properties in this temperature range.
  • the material must have an elasticity factor of between 5NM and 20 NM, in particular between 6.6 NM and 17.6 NM measured according to standard DIN 53515.
  • the tensile strength of the material is preferably between 0 , 79 MPA and 1.2 MPA measured according to standard DIN 53455.
  • the resistance to pressure is at least 40 kg / cm 2 and preferably 45 kg / cm 2 measured according to standard DIN 53454.
  • the deformation at pressure measured according to DIN 53572 is preferably from 12% to 15.9% at 70 ° C for 24 hours and from 6.3% to 6.6% at 23 ° C for 72 hours.
  • the material used is recycled rubber obtained from used tires. These used tires are shredded in powder and the ground rubber is then amalgamated with polyurethane to form by different pressure molding parts of the dust jacket.
  • recycled rubber is that this material allows the manufacture of inexpensive jackets and offers a solution for recycling used tires.
  • Another benefit of using rubber is that when the dust jacket and the rail are put in the ground, the rubber of the dust jacket gives better grip to the tires vehicles and thus limits the effects of the lack of grip that cause the steel rails.
  • the jacket preferably has a length of 1.20 m corresponding to a modulation which adjusts to the conventional length tram rails.
  • the jacket is provided with fixing means (6, 7 and 8) arranged to fix the different parts together. These means of attachment have a protrusion 6 applied to the outer face first and second parts of the dust jacket. In this protuberance is provided with a notch 7 in which is housed a concrete iron 8. The concrete iron wraps the jacket and thus connects the three parts between them.
  • the advantage of using fastening means is that the mounting jackets can be done before placing the rail in the ground.
  • the rail provided with its jacket can be placed as a whole.
  • the rail with its cover can thus be transported and delivered as a assembly and assembly of the jacket must not be done on the site where the rail is installed.
  • the jacket has a profile 10, 11 and 12 which matches the geometry 13, 14 and 15 of the rail. This is important because the jacket must be in direct contact with the rail.
  • the purpose of the jacket is to absorb the vibrations produced by the tram or other vehicle which runs on the rail. The rotation of the steel wheels of the tram on the steel of the rail causes induction of vibrations in the rail. Without the presence of jackets these vibrations are transmitted from the ground to buildings which run along the tram tracks, causing not only damage to buildings but also nuisance to residents who are sometimes disturbed in their sleep due to these vibrations.
  • the presence of the jacket now makes it possible to absorb the major part of these vibrations and thus significantly reduce their induction in the soil. Since the jacket perfectly fits the rail geometry, the vibrations induced in the rail are transmitted to the elastic and resistant material of the jacket which absorbs them. When the dust jacket contains the three parts both lateral vibrations as transverse are absorbed and their induction in the soil is significantly reduced.
  • the first 2 and second 3 part of the jacket have each an angle geometry at their lower part 20, 21 which comes take the angled section 22, 23 of the third part of the jacket. So the different parts of the dust jacket are complementary to such so as to substantially envelop the lateral and lower sides of the rail.
  • the jacket is also provided with a perforation 24, 25 in its first 2 and second part 3 intended for the passage of a rail spacer 16 as shown in Figure 3.
  • the spacer can also be used as a means of fixing the jacket to the rail, for example example using bolts 17.
  • the external geometry of the first and second part of the dust jacket has a hollow in order to strengthen on the one hand the structure of the dust jacket and secondly allow to form a concrete formwork which is poured along the rail when the latter is placed in the ground. Concrete comes thus to be lodged in this hollow and makes it possible to maintain the rail with its jacket in place.
  • the distance d (figures 2 and 4) from the upper edge of the first 2 and second 3 part of the jacket, arranged to be juxtaposed on the face upper of the rail, has a width substantially equal to 42 mm. This allows to arrange between two rails a distance corresponding to five klinker 18 and a half and thus facilitates the filling of the center of the track.
  • the lower form of the dust jacket is provided in the form of a pin, so as to enclose the third part 4 during the prepose.
  • FIG. 5 illustrates another embodiment of a anti-noise device according to the invention.
  • the dust jacket has only one part 30 placed against the first flank, that is to say the outer flank of the rail 5.
  • the jacket is used here not only anti-noise device, but also single shoulder profile.
  • the jacket materializes the filling of the rails outside of the track and separates the rail from the concrete filling of the roadway. Concrete does will therefore no longer be in direct contact with the rail, which has the consequence that the vibrations induced by the tram in the rails will, at least in large part, absorbed by device 30 and will no longer be directly induced in concrete. Concrete will therefore be less likely to crack and break due to vibrations. Since the jacket is installed directly against the rail, it also serves as a gasket for area.
  • the jacket 30 has a flat profile 31 on its side outside and has a recess 32 at its lower part. This allows overlap the rail fasteners, applied either on wooden sleepers, either on precast or poured concrete sleepers.
