Das deutsche Patent 40 04 208 zeigt eine Schalldämmvorrichtung an Straßenbahnschienen, bei der stangenartige Formteile vornehmlich aus Polyurethan-gebundenem Altgummi verwendet werden. Diese Formteile sind den sogenannten Kammern der Schiene angepaßt, um den Schall, der in den Schienen entsteht, großflächig aufzunehmen und möglichst zu dämpfen. Der Schienenkopf weist notgedrungen freie Flächen auf, über die die Räder der Schienenfahrzeuge rollen und über die Schall in die Luft abgegeben wird.German patent 40 04 208 shows a sound insulation device on tram rails, at the bar-like Molded parts made primarily from polyurethane-bonded waste rubber be used. These molded parts are the so-called Chamber of the rail adapted to the sound that in the Rails are created to accommodate large areas and, if possible, to dampen. The rail head necessarily has free areas on which the wheels of the rail vehicles roll and through which sound is released into the air.

Straßenbahnschienen und Eisenbahnschienen werden entweder im Schotterbett oder in sogenannter fester Fahrbahn verlegt. Es ist bekannt, daß die Schallabstrahlung bei Schotterbetten geringer ist als bei festen Fahrbahnen. Zur Verringerung der Schallemission hat man auch bereits Absorptionsbeläge an den Gleisen angebracht. Dabei handelt es sich um Altreifengranulat, das vor Ort als Belag aufgeschüttet und mit Kunststoff gebunden wird.Tram tracks and railroad tracks will be either in the ballast bed or in a so-called slab track relocated. It is known that the sound radiation at Ballast beds is less than with solid carriageways. For There is already a reduction in sound emissions due to absorption coatings attached to the tracks. It is about around used tire granulate, which was heaped up on site as a covering and is bound with plastic.

Der Erfindung liegt die Aufgabe zugrunde, die Schallabstrahlung bei Schienengleisen mit festen Fahrbahnen zu verringern.The invention is based, which Sound radiation on rail tracks with fixed carriageways to reduce.

Fig. 1 zeigt einen Querschnitt durch ein Eisenbahn-Schienengleis mit sogenannter fester Fahrbahn. Bei dieser enthält die Gleisunterkonstruktion eine Betonplatte 2, an der die Schienen 10 befestigt sind. An den Flanken der Schienen 10 liegen Ausfüllkörper 30 und 40 aus Polyurethangebundenem Altgummi an, und zwischen den Schienen 10 erstrecken sich Schallschluckmatten 50.Fig. 1 shows a cross section through a railroad track with a so-called slab track. At this the track substructure contains a concrete slab 2 the rails 10 are attached. On the flanks of the Rails 10 are filling bodies 30 and 40 made of polyurethane-bonded Waste rubber, and extend between the rails 10 sound absorption mats 50.

Fig. 2 stellt einen vergrößerten Ausschnitt aus Fig. 1 im Bereich einer Schiene 10 dar. Wie ersichtlich, weist die Schiene 10 einen Schienenkopf 11, einen Schienensteg 12 und einen Schienenfuß 13 unter Bildung von Schienenkammern 14 und 15 auf. Der Schienenfuß 13 ruht unter Zwischenlage einer Gummi- oder Kunststoffschicht 22 auf der Betonplatte 2 auf und wird paarweise mittels Schienenfuß-Klemmeinrichtungen 20 an dieser Platte befestigt.FIG. 2 shows an enlarged detail from FIG. 1 in the area of a rail 10. As can be seen, points the rail 10 has a rail head 11, a rail web 12 and a rail foot 13 to form rail chambers 14 and 15. The rail foot 13 rests with an intermediate layer a rubber or plastic layer 22 on the concrete slab 2 on and is in pairs by means of rail foot clamping devices 20 attached to this plate.

Der Ausfüllkörper 30 weist im großen und ganzen gesehen einen trapezförmigen Querschnitt mit vier Seiten auf, die als Kammeranlageseite 31, Randseite 32, Oberseite 33 und Unterseite 34 bezeichnet werden. Die Breite des Ausfüllkörpers 30 übersteigt seine Höhe. Die Kammeranlageseite 31 schmiegt sich dem Umriß der Schiene 10 im Bereich der Kammer 15 und teilweise auch des Kopfes 11 an und wird beim Einbau eingeklemmt sowie gegebenenfalls auch eingeklebt. Die Randseite 32 ist hier gerade, abgeschnitten dargestellt, kann aber auch Ausbildungen aufweisen, wie sie zu weiterführenden Schallschluckmaßnahmen passen. Die Unterseite 34 ist mit einer Aussparung 35 zur Aufnahme des Klemmenkopfes 21 versehen.The filler body 30 generally has seen a trapezoidal cross-section with four sides on, as the chamber system side 31, edge side 32, top 33 and bottom 34 are referred to. The width of the Filler body 30 exceeds its height. The chamber plant side 31 hugs the outline of the rail 10 in the area the chamber 15 and partly also of the head 11 and will pinched during installation and possibly also glued in. The edge side 32 is cut straight here shown, but can also have training such as fit to further sound absorption measures. The bottom 34 is with a recess 35 for receiving the terminal head 21 provided.

Die Oberseite 33 des Ausfüllkörpers 30 ist im Hinblick auf Absorption von Luftschall gestaltet, der von den freien Flächen des Schienenkopfes 11 ausgeht. Zum Befahren der Schiene wird ein strichpunktiert dargestellter Freiraum am Schienenkopf 11 benötigt, der demgemäß nicht durch die balkenartigen Ausfüllkörper 30 und 40 eingenommen werden darf. Die Oberseite 33 des Ausfüllkörpers 30 führt um diesen Freiraum herum generell nach oben ansteigend und weist Noppen 36 und Vertiefungen 37 auf, die zur Luftschallabsorption dienen. Zusätzlich können schräge Bohrungen 38 vorgesehen sein, um Regenwasser in Richtung der Seite 32 abzuleiten. Die Bohrungen 38 dienen auch der Schallabsorption.The top 33 of the filler body 30 is in the Designed for absorption of airborne sound by the free surfaces of the rail head 11 starts. To drive on the rail is a dash-dotted line Free space on the rail head 11 is required, which accordingly does not taken by the beam-like filler 30 and 40 may be. The top 33 of the filling body 30 leads around this free space generally rising upwards and has knobs 36 and depressions 37 which are used for airborne sound absorption to serve. In addition, oblique bores 38 be provided to rainwater towards page 32 to derive. The holes 38 also serve to absorb sound.

Der obere Bereich 39 des Ausfüllkörpers 30 kann auch durch geschüttetes, grobkörniges, jedoch Polurethan-gebundenes Material gebildet werden, um Lücken zum Abfluß des Regenwassers zu bilden und um den Luftschall in den Lücken aufzunehmen und zu absorbieren. Der restliche Ausfüllkörper besteht aus verdichtetem Material, das auch wasserundurchlässig hergestellt werden kann. Der Bereich 39 stellt einen Luftschallabsorptionsbereich und der verdichtete Bereich des Ausfüllkörpers einen Körperschalldämmbereich dar.The upper region 39 of the filler body 30 can also through poured, coarse-grained, but polyurethane-bound Material formed to fill gaps to drain the To form rainwater and around the airborne sound in the gaps absorb and absorb. The rest of the filler consists of compressed material that is also impermeable to water can be manufactured. The area 39 represents one Airborne sound absorption area and the compressed area of the Filler body represents a structure-borne sound insulation area.

Der balkenartige Ausfüllkörper 40 ist ähnlich gestaltet wie der Ausfüllkörper 30. Diesem entsprechende Teile sind mit Bezugszeichen belegt, deren Endziffer den korrespondierenden Ziffern des Teils 30 entsprechen. Das Element 40 ist aber an der Seite 41 schmäler ausgebildet, weil der Schienenkopf 11 an der Innenseite des Gleises frei bleiben muß, um den Radkranz aufzunehmen. Demgemäß beginnt die Oberseite 43 erst in einem gewissen Abstand von der Schiene zu steigen. Die Unterseite 44 weist entweder eine Aussparung 44a auf oder verläuft insgesamt parallel zur Unterseite 34 des anderen Elements 30, um den Rand der Matte 50 einzuklemmen. Die Oberseite 43 weist wiederum Noppen 46 und Vertiefungen 47 auf, um als Luftschallabsorptionseinrichtung zu wirken. Es sind wiederum entweder durchgehende Bohrungen 48 vorgesehen, oder der Abschnitt 49 enthält genügend Lücken, um Regenwasser abzuführen.The beam-like filler body 40 is similar designed like the filler body 30. Corresponding to this Parts are provided with reference numerals, the final digit of which correspond to corresponding digits of part 30. The However, element 40 is narrower on side 41, because the rail head 11 is free on the inside of the track must remain to accommodate the rim. Accordingly begins the top 43 only at a certain distance from the Rail to rise. The bottom 44 either has one Recess 44a or overall runs parallel to Bottom 34 of the other element 30 to the edge of the mat 50 pinch. The top 43 in turn has knobs 46 and depressions 47 to act as an airborne sound absorption device to act. Again, they are either continuous Bores 48 provided, or section 49 contains enough gaps to drain rainwater.

Die Matte 50 ist aus Altgummigranulat mit Polyurethan-Bindung hergestellt und kann gegebenenfalls eine genoppte Oberfläche aufweisen, um den Luftschall besser absorbieren zu können.The mat 50 is made from waste rubber granulate Made of polyurethane bond and can optionally be a have a nubbed surface to make the airborne sound better to be able to absorb.

Fig. 3 zeigt Ausfüllkörper 30 und 40, die an die Verhältnisse bei Rillenschienen angepaßt sind. Solche Rillenschienen werden vornehmlich als Straßenbahnschienen verwendet, die in eine Fahrbahn einzubinden sind. Deshalb wird ein ebener Freiraum oberhalb des Schienenkopfes 11 vorausgesetzt. Die Rillenschiene umfaßt außer Kopf 10, Steg 12, Fuß 13 noch eine Rille 16 und einen Führungssteg 17. Ferner^ werden Straßenbahnschienen über Spurstangen 18 miteinander verbunden, die am Schienensteg über eine Kopfschraube 19 befestigt werden. Um diese Befestigungsmittel aufzunehmen, sind Aussparungen 31a und 41a an den Seiten 31 und 41 der Ausfüllkörper 30 und 40 vorgesehen. Einige der balkenartigen Ausfüllkörper 40 weisen außerdem an ihren Enden jeweils eine Aussparung 40a auf, um die Spurstange 18 aufzunehmen.Fig. 3 shows filler body 30 and 40, which to the Ratios for grooved rails are adjusted. Such Grooved rails are primarily used as tram rails used, which are to be integrated into a lane. That's why becomes a flat space above the rail head 11 provided. The grooved rail includes head 10, web 12, foot 13, a groove 16 and a guide bar 17. Furthermore ^ tram rails over tie rods 18th connected to each other on the rail web via a cap screw 19 are attached. To these fasteners recesses 31a and 41a on the sides 31 and 41 of the filling bodies 30 and 40 are provided. Some of the beam-like filler body 40 also point to their Each have a cutout 40a around the tie rod 18 to record.

Wie im Ausführungsbeispiel der Fig. 2 sind obere Bereiche 39 und 49 vorgesehen, die im Hinblick auf Luftschallabsorptionen mit Noppen 36, Vertiefungen 37 und Bohrungen 38 versehen sind. Außerdem können diese Bereiche 39, 49 aus grobkörnigem Altgummi hergestellt sein, um trotz Polyurethanbindung genügend Lücken zum Abfluß von Regenwasser zu bilden und um den Luftschall in den Lücken aufzunehmen und zu absorbieren. Der restliche Ausfüllkörper besteht vorzugsweise aus stärker verdichtetem Material und kann wasserundurchlässig sein.As in the embodiment of Fig. 2 are upper Areas 39 and 49 are provided with regard to airborne sound absorption with knobs 36, recesses 37 and Bores 38 are provided. These areas can also 39, 49 made of coarse-grained waste rubber, despite Polyurethane bond enough gaps to drain rainwater to form and to absorb the airborne sound in the gaps and absorb.
