Definitions

• the invention relates to a sound attenuation device on tram rails, which have a rail head, a rail web, a rail foot and both sides of the rail web rail chambers.
• Sound attenuation devices on tram rails are widely known and have chamber filling elements of sound-insulating material, which partially surround the rails and thereby engage in the so-called rail chambers.
• a sound-insulating material recycled old rubber can be used, which is bound with polyurethane (DE 40 04 208 A).
• Moldings made of rubber or rubber-like materials are also used for railroad level crossings (DE-U 63 04 909, EP-B 0 281 013, EP-A 0 590 342). In this case, lower and upper, elongated moldings are used, which engage with a partial area in the rail chambers.
• the Kammer loungelletti are to be applied for sound insulation on tram rails, which extend along the entire rail.
• thermal expansion and shrinkage can cause the gaps between the shaped bodies to widen. Namely, if the moldings are installed during the summer at summer temperatures, so are elongated by thermal expansion, they are in wintry Temperatures shrink, resulting in gaping gaps between the moldings.
• the invention has for its object to provide a sound attenuation device on tram rails, in which there is essentially no widening of gaps and loosening the Kammerhellimplantation or the moldings in the composite, even if the sound attenuation device is subject to large temperature fluctuations.
• connection shaped bodies can likewise be produced from sound-insulating material, which are preferably produced at a higher pressure than the elongate shaped bodies.
• the engagement recesses can be attached to the outside of the moldings and then consist of a blind hole and a longitudinal recess.
• the lower elongated moldings be shorter, corresponding to the distance of the

• the tramway rail 1 has a rail head 10 with groove 11, a rail web 12 and a rail foot 13. Between the rail head, rail bridge and rail foot extend the outer rail chamber 14 and the inner rail chamber 15. The lower left mold body 2 and the upper mold body 3 are in the rail chamber 14 and the lower right mold body 2 and the upper mold body 4 are clamped in the rail chamber 15 , The moldings 2/3 and 2/4 each form a Kammerglallelement, but the respective lower moldings 2 bridge or interrupt the gaps between adjacent upper moldings 3 and 4 respectively.
• the molded body 2 shows a slot-shaped recess 20 to engage around the rail web 13 and to clamp on this.
• the molded body 2 further shows a roof 21 with which it extends into the rail chamber 15. Below the roof 21 are recesses 22 for saving material, which form a series of downwardly open niches, as indicated in the phantom in Fig. 4.
• a web 23 is also formed.
• the end surface 24 is "cut" by a niche partition, with even shorter moldings 2, the "cut” can also be made through a niche.
• the side surface parallel to the rail web 12 is denoted by 26.
• the cover 6 (FIG. 3) has an edge seam 61, which can be used for fastening purposes on the adjacent molded bodies 2.
• FIG. 6 and 7 show the upper outer molded body 3. It has a region 30 adapted to the upper region of the rail chamber 14 and extends with its upper side 31 to near the upper end of the rail head 10.
• the molded body 3 also has material-saving recesses 32, which are niche-shaped and open down.
• the lower left edge of the molding 3 is replaced by a longitudinal recess 37.
• an engagement recess 33 for cooperation with the connecting body 5 is provided in each case, which is described in more detail with Fig. 12.
• the molded body 4 has a region adapted to the rail contour region 40 and an upper side 41, which extends to near the plane of the top of the rail head 10.
• Materialersparnisaussparungen 42 are provided, which are niche-like separated by web walls. The lower left edge of the molding 4 is through a
• Engagement recesses 43 are provided, which are designed to cooperate with the connecting body 5.
• the bracket-shaped connecting body 5 has a U-shaped cross section on with a connecting leg 50 and two U-legs 51, 52, which form staple extensions. On their inside, the legs 51, 52 each have a locking rib 53.
• the connecting body 5 is designed to engage in adjacent engaging recesses 33 and 43 of adjacent upper moldings 3 or 4, ie they take a negative mold to the connecting body 5 a.
• the engagement recesses 33 and 43 thus consist of a blind hole with a detent groove for receiving the legs or clip extensions 51, 52, and a longitudinal recess for receiving the connecting leg 50 of the molded body 5. This is shown in Fig. 12, where two continuous moldings 3 clamped together become.
• the moldings 4 are similarly clamped together by means of the connecting body 5. The result is a bond between continuous upper moldings 3 and 4, which ensures that the upper moldings can not loosen, even if they are exposed to strong temperature differences.
• 13 and 14 show a modified embodiment of the upper outer molded body 3.
• the top 31 also extends an edge groove 35 which can be used to introduce potting compound between the sound insulation and the adjacent street level.

• an integral chamber filling element 100 is shown mounted on a rail 1, which, so to speak, has grown together integrally from the moldings 2 and 3.
• the foot below the recess 20 has been omitted.
• the Kammer Schollele ⁇ tente Operaend lake 134 and 124a, 124b are formed, which correspond to the end surfaces 34 and 24 of the moldings 3 and 2 and which are arranged offset from each other at a certain distance.
• Fig. 18 shows the joint 110 between adjacent Kammer hypollmaschinen 100 in a modified Embodiment.
• the joint 110 is formed by partial end surfaces of the chamber filling members, which are shown externally in gap portions 110a-110f.
• the mutual offset of the partial end faces is smaller and lies within the length of the connecting legs 50 of the connecting body 5.
• the installation of the soundproofing device is carried out as follows.
• the lower moldings 2 are placed on the rail foot 2, and the rail is mounted on a concrete slab or over railway sleepers.
• the upper moldings 3 or 4 are displaced obliquely from above into the remaining space of the rail chambers offset from the lower moldings 2 until they engage with their longitudinal recesses 34 and 44 on the webs 23. Then, adjacent ends of the molded bodies are connected to each other by means of the connecting bodies 5 and clamped. This results in a sufficiently strong bond between the moldings and the tram track.
• the cover hoods 6 for the rail mounting heads can be mounted by tacking the edge seam 61 to the adjacent moldings 2.
• the brackets 5 are inserted into the engagement recesses to provide a tight bond of the Kammer hypollemia.
