Definitions

  • the invention relates to a sound attenuation device on tram rails, which have a rail head, a rail web and a rail foot, between which extend rail chambers, and which are installed in a roadway.
  • EP A 2 088 240 A2 represents prior art under Art. 54 (3) EPC and relates to a system and method for filling a joint between a rail and an adjacent surface. Chamber filling in the Rail chambers form a joint bottom to an outer joint, which is filled with the potting material. When backfilling an insert element is inserted into the joint to prevent cracking in the potting material.
  • a sound absorbing device is made DE 40 04 208 A1 known.
  • Joint pouring compound is based on bitumen, but also of permanently elastic hardening materials, such as polyurethane or polysulfide resin, which have a high elasticity.
  • This Fugenvergussmassen have a strong adhesion to the rail head or on an adjacent road surface and thus allow the good sealing of the soundproofing against water penetration. This is especially important for elastic track constructions.
  • the price per kilogram of sealing, after curing elastic joint grout is high. To achieve a permanent seal, a relatively large amount of joint grout must be used.
  • the joint size is determined by the rail geometry and the chamber filling elements.
  • the invention has for its object to save the installation of soundproof tram rails in roadways, especially in elastic track constructions, Fugenvergussmasse without endangering the seal against the ingress of water into the roadway between the rail head and pavement.
  • the lateral adhesive surface or interface of the Fugenverguss stresses in the vertical direction is in the range between 20 and 40 mm. For this area, permanent adhesion of the grout to the rail head and sound insulation device can be ensured, while at the same time the joint grout is handled relatively sparingly.
  • the invention can be used with any type of tramway rail, in which the rail is incorporated into a roadway. Since the grooved rail is particularly suitable for installation in a roadway, the invention is preferably applied to grooved rails, although the application with Vignol rails is also possible.
  • the grooved rail is asymmetrical, and so different widths of the joints on both sides of the rail to the road surface result. For the groove-close FugenvergussAvem a width in the range of 10 to 30 mm is selected and for the groove-distant Fugenverguss endeavor a width in the range of 30 to 70 mm.
  • This shows a cross section through a roadway in the area of a tram track.
  • Trained as a grooved rail tram 1 rests on a sound-absorbing, elastically yielding bedding layer 2 and is surrounded by moldings 3, 4, which form a sound insulation device.
  • the roadway comprises a base layer 5, for example of reinforced concrete, on which the bedding layer 2 rests, a filling layer 6, for example of concrete, a binder layer 7, for example bituminous, and a wear layer 8, also bituminous, for example.
  • the joints between the rail head and the wear layer 8 are each filled by a Fugenverguss stresses 9 and 10 respectively.
  • the road may consist of concrete or paving of natural or concrete blocks. Also Vignol rails can be used.
  • the grooved rail 1 has a rail head 11 with groove 12, a rail web 13 and a rail foot 14. On both sides of the rail web 13 extend between the rail head and rail foot ever a rail chamber which, as shown, of the mold parts. 3 or 4 are filled, which accordingly represent Kammer Strukturllense, but with their width overhang the rail chambers.
  • the outside of the Kammer hypollelements 3 has a distance from the groove-distant portion of the rail head 11 of about 30 to 70 mm, while the outside of the Kammerchellissellisses 4 from the groove-near rail head portion has a distance of 10 to 30 mm.
  • the general upper side 31 or 41 of the respective chamber filling elements 3 and 4 has a distance from the surface of the wear layer 8 which lies in the range between 20 and 40 mm.
  • a filler 30 or 40 which may be formed as an insert or as a projection on the Kammer hypollelement 3 and 4 and is located above the general top 31 and 41 of the Kammer hypollense 3 and 4 respectively.
  • the filler bodies 30, 40 calculated at their base, extend at a distance of at least 2 mm (preferably in the range of 2 to 12 mm) to the rail head 11. In the case of projections, these have the shape of ribs with rounded cross-section at the immersing Top up.
  • the cross section may be half round or half oval, as shown.
  • the cross-sectional area of the filling body 30 or 40 occupies about 15 to 40% of the cross-sectional area between the rail head, the wear layer 8 and the general upper side 31 and 41 of the chamber filling elements 3 and 4, respectively.
  • joint grout 9 and 10 are saved on joint grout during the production of the joint grout, which can account for up to 40% of the joint grout.
  • Fugenvergussmasse a high-quality elastomeric plastic is preferred, on the basis of polyurethane or polysulfide. There are technical advantages for both grouting types.
