Definitions

  • the invention relates to a railway superstructure with an elastic base Structure-borne noise reduction and the use of an appropriate mat or Train.
  • a generic document for track support systems with ballast bed is known from DE 43 02 299 A1.
  • a mat made of closed-cell foamed, cross-linked rubber material is used as the ballast bed underlay, which can be covered with a protective layer of non-foamed and elastic, permanently pressure-resistant rubber material on the top to protect the foam-like material, the underlay being glued to the protective layer.
  • a textile fabric can also be used as a liner as a further protective layer, which can be arranged both above and below the rubber plate.
  • AT-PS 357 188 is an elastic ballast bed underlay made of two overlapping loosely arranged rubber mats for sound and Vibration damping known. An adjustment of these mats to one wide frequency range, the vibrations to be damped is natural not possible.
  • ballast bed mat for use as a mat for ballastless ones Superstructure is not revealed ..
  • the maximum allowable sink under Traffic load therefore limits the insulating effect to frequencies of> 50 Hz.
  • the maximum allowable sink under Traffic load therefore limits the insulating effect to frequencies of> 50 Hz.
  • the insulating effect limits the insulating effect to frequencies of> 50 Hz.
  • threshold underlays especially since only threshold shoes are available, because otherwise the "firm Roadway "becomes unstable.
  • ballast mats or underlays for ballastless track support systems are particularly necessary to get the damping in the area of the natural frequencies of the track support systems and adjacent structures under control. Furthermore, it is described that the static and dynamic stiffness of the polyurethane foam mats can be set to approximately the same level and a relative softness is achieved with a degressive course of the spring characteristic.
  • the elastic base acts as a spring in a spring-mass system, whereby this track support system with the overlying sleepers and rails is damped as a vibrating mass.
  • the effectiveness of this polyurethane material is in particular in the range between 10 and 45 Hz, with a dynamic rigidity of 0.03 - 0.09 N / mm 3 under preload of 0.06N / m 2 .
  • Water-permeable moldings made of waste rubber with PUR as a binding agent Use as a noise-damping track substructure is also in DE 41 00 481 A 1 mentioned.
  • DE 43 15 215 A1 discloses a sleeper shoe that consists of two Layers can be put together, namely a rubber-like Material as materials contacting the threshold underneath and one another layer of nonwoven fabric.
  • a geotextile is mentioned as an example as fleece, which can be glued to the elastomer or rubber-like material.
  • the rubber-like material should have a minimum thickness of 8 mm and a hardness from 50 to 60 Shore A. Evidence of an essential Structure-borne noise insulation is not given in this document.
  • EP 0 549 559 A1 and US 4 609 144 include a superstructure Concrete sleepers resting on a rubber-elastic intermediate layer, described.
  • the intermediate layer is intended to transmit structure-borne noise dampen as much as possible and consists essentially of composite material Used tires with reinforcements made of fabric, with corresponding rubber-elastic adhesive are connected.
  • a water permeable Asphalt layer under the liner is intended to transmit structure-borne noise insulate.
  • For ballast beds under the liner can also water-permeable fleece, in particular plastic fleece, the a sponging of mineral and organic particles from the Ballast bed prevented.
  • Asphalt is a rheological and insofar inconsistent material; the fleece obviously has no soundproofing Properties, just filter effect.
  • Ballast on a mineral wool slab can rest to at high frequencies of 500 Hz or more to be able to offer good absorption values for airborne sound.
  • a layer of 3 to 6 cm of mineral wool, supplemented by a layer on top of it Layer of mineral grains from 8 to 20 cm thick, laid out next to the sleepers on the railway superstructure, should sound in the upper Absorb frequency range.
  • DE 32 43 620 A1 shows a sealing material made of reinforced rubber bitumen for ballast beds, bridges, etc., which serves to seal the structure.
  • the sealing membrane has a mineral fiber or organic fiber layer on the top, to prevent damage to the sealing membrane from sharp gravel and the corresponding mechanical stress. There is no reference to structure-borne noise insulation in either document.
  • the problem underlying the invention is an elastic base both for track support systems with a ballast bed and with a ballastless one Propose superstructure with which effective structure-borne noise insulation is achievable.
  • the two materials cannot be mixed; the mat will formed in two layers, the layer of rubber material as that Ballast bed bearing or the concrete body for solid carriageway upper Layer is used. At the same time it serves as a load distribution plate and Protective layer for the mineral wool layer below.
  • Both layers can be prefabricated and with glue or mechanical binders, such as building material needles, coupled together be and be installed as a one-piece plate.
  • the two plates or mats or sheets are preferably offset to each other so that you always achieve an overlap with the neighboring plate and avoiding the two layers colliding in the same plane.
  • Such a duplex arrangement is also assembled in webs possible and known for sub-ballast mats.
  • the layer thickness for the upper layer is approximately 10-35 mm, preferably 15-30 mm, in the standard case for loading by track bodies of trams approximately 25 mm.
  • the thickness of course depends on the statistical preload and the desired stiffness to match the surface. The thickness can be reduced on loose sandy soils, and the thickness is greater on rocky ground due to a lack of self-damping.
  • a manageable mass for the first layer consists of about 25-50% by weight of polyurethane, preferably about 35-40% by weight, 40-55% by weight of rubber granulate obtained from old tires, and rubber powder, preferably about 45% by weight, with additives for adjustment the hardness of the layer so produced.
  • Mineral wool usually available in the building materials trade as a one-sided sheet of glass fiber or rock wool laminated with a vapor barrier, is used in addition to polystyrene panels as impact sound insulation in building construction.
  • the lower layer can also consist of several layers of thin mineral wool.
  • the lamination can also be designed as an integral skin of the rubber material or, in the case of the mineral wool, can be equipped as a cover film in order to obtain a separation from the substrate or an affinity for bonding to the upper layer, depending on which adhesive is used.
  • the support according to the invention can reduce the vibration in the low-frequency range of 10-45 Hz by 4-12 dB and, in the same size, reduce the secondary airborne noise resulting from the component vibration.
  • FIG. 2 shows the base formed as a duplex plate with an upper one Layer 1 made of polyurethane-bonded rubber granulate, under which around 100 mm offset according to the offset 5, a rock wool plate 2 is arranged.
  • the width of the plate is approximately 1000 mm, its length is approximately 3000 mm.
  • the offset 5 can be seen again in FIG. 1; it enables the plates in the overlapping joint to create a secure base for the Obtain track support system.
  • the rock wool plate 3 can with on the bottom be covered with a PE film so that moisture or stones do not get in from below the lower layer 3 can penetrate.
  • Between the upper layer 1 and the lower layer 3 is an adhesive layer 2 with which the Plate layers 1 and 3 are combined to form a unit plate can.
  • a grooved rail 10 for a tram track is inserting one elastic rails underlay 9 stored on a concrete support plate 8 and opposite the lateral paving 12 by chamber stones 11 and one Potting compound 14 isolated from vibration.
  • the the track support system Representing concrete slab 8 is compared to the plan by 7 by one Cleanliness film, e.g. a PE film 6, separated, on which the two-layer duplex plate according to the invention with the upper layer 1 and the lower Layer 3 rests, thus cushioning the concrete slab 8.
  • At the side of the concrete slab 8 is also a compared to the formation or the surrounding structures 15 two-layer plate 1.3 according to the invention arranged to close sound bridges prevent.
  • the resulting joint between the paving and the Surrounding structure is by a potting compound 13 above the elastic Duplex plate closed.
