Description

Die Erfindung betrifft ein Material zum Einbau von Schienen von schienengebundenen Fahrzeugen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a material for installing rails of rail-bound vehicles, according to the preamble of claim 1.

Eingebettete Straßenbahnschienen sind z. B. durch die DE-C-6 36 589 bekanntgeworden. Hier sind zwischen einer Unterbettung und einem Schienenfuß elastische Schichten unterschiedlicher Elastizität vorgesehen. Als Zuschlagstoffe für das elastische Material sind Sand, Zement und Kies vorgesehen. Das gleiche elastische Material wurde vorgeschlagen um die Schiene seitlich gegen das angrenzende Pflaster im Hinblick auf Erschütterungs- und damit Lärmemission zu isolieren.Embedded tram rails are e.g. B. become known from DE-C-6 36 589. Here elastic layers of different elasticity are provided between an underbedding and a rail foot. Sand, cement and gravel are provided as additives for the elastic material. The same elastic material has been proposed to isolate the rail laterally from the adjacent pavement with regard to vibration and thus noise emissions.

Aus der DE-C-8 15 046 ist ein Verfahren zum Einbau einer Staßenbahnschiene und eine eingebaute Straßenbahnschiene bekanntgeworden, bei dem zwischen dem Schienenfuß und dem Unterbau eine Zwischenschicht aus sog. plastischem Beton aufgetragen wird. Dieser plastische Beton besteht dabei aus bituminösen Bindemitteln höherer Viskosität und Mineralmassen, die aus Split, Sand und Füllern bestehen.From DE-C-8 15 046 a method for installing a tram rail and a built-in tram rail has become known, in which an intermediate layer of so-called plastic concrete is applied between the rail foot and the substructure. This plastic concrete consists of bituminous binders of higher viscosity and mineral masses, which consist of split, sand and fillers.

Die CH-A-4 98 979 zeigt eine in ein Elastomer eingegossene Schiene. Um die Elastizität des Elastomeres zu erhöhen wird es aufgeschäumt oder mit feinverteiltem Kork versehen.CH-A-4 98 979 shows a rail cast in an elastomer. To increase the elasticity of the elastomer, it is foamed or provided with finely divided cork.

Aus der FR-A-2125 747 kann ein Material zum Vermindern von Lärmemission entnommen werden, welches aus einem Polyurethan und Kautschukpulver besteht.From FR-A-2125 747 a material for reducing noise emission can be taken, which consists of a polyurethane and rubber powder.

In neuerer Zeit wird zur Herstellung von elastischen Unterfütterungen mit schwingungsdämpfenden Eigenschaften ein lösungsmittelfreies, elastisch aushärtendes 2-Komponenten-System auf Polyurethanbasis, z. B. ICOSIT (eingetragenes Warenzeichen) verwendet, dem Sand zugegeben wird ; vgl. Prospekt der Lechler Chemie « Icosit KC 330/U vom Januar 1984, in dem ein Material zum Einbau von Schienen gemäß dem Oberbegriff des Anspruchs 1 beschrieben ist.In recent times, a solvent-free, elastically curing, two-component system based on polyurethane, for example, has been used to produce elastic relines with vibration-damping properties. B. ICOSIT (registered trademark) to which sand is added; see. Brochure of Lechler Chemie «Icosit KC 330 / U from January 1984, in which a material for installing rails according to the preamble of claim 1 is described.

Um eine weitere Senkung der Schnellepegel bei Straßenbahnfahrbetrieb, - die sich in Luftschallpegel innerhalb von Gebäuden ausdrücken -zu erreichen, können die Straßenbahnschienen auf federnd gelagerten Betonplatten befestigt werden. Auch ist eine Abschirmung der Gebäude durch sog. Erdschlitze möglich. Hierbei werden in einem Abstand von einem zu schützenden Gebäude doppelte Schlitzwände angeordnet, wobei der Zwischenraum mit einem weichen Material aufgefüllt werden muß. Die doppelten Schlitzwände müssen dabei mehrere Meter unter die Fundamentunterkante reichen. Weiter ist eine Maßnahme zur Dämpfung des Schnellepegels bekanntgeworden, bei denen der gesamte Bereich des zu schützenden Gebäudes unterhalb der Erdoberfläche mit einer weichen Außenhaut verkleidet wird. Mit den eben beschriebenen Maßnahmen lassen sich Pegelsenkungen zwischen 7 und 10 dB erreichen.In order to further reduce the speed level during tram operation - which are expressed in airborne noise levels inside buildings - the tram rails can be attached to spring-loaded concrete slabs. Shielding of the buildings by so-called earth slots is also possible. In this case, double diaphragm walls are arranged at a distance from a building to be protected, the interspace having to be filled with a soft material. The double diaphragm walls must reach several meters below the bottom edge of the foundation. Furthermore, a measure for damping the rapid level has become known, in which the entire area of the building to be protected is covered with a soft outer skin below the earth's surface. With the measures just described, level reductions between 7 and 10 dB can be achieved.

Der Erfindung liegt die Aufgabe zugrunde, ein Material zum Einbau von Schienen für schienengebundene Fahrzeuge zu schaffen, mit dem es möglich ist, eine Verminderung der Übertragung von Körperschall, - und damit des Störpegels -, der von diesen Fahrzeugen ausgeht, zu erreichen und die Zerstörungsanfälligkeit des Dämm-Materials beim Reparaturschweißen zu vermindern.The invention has for its object to provide a material for installing rails for rail-bound vehicles, with which it is possible to achieve a reduction in the transmission of structure-borne noise, and thus the level of interference, which emanates from these vehicles, and the susceptibility to destruction to reduce the insulation material during repair welding.

Diese Aufgabestellung wird durch den Gegenstand des kennzeichnenden Teils des Anspruchs 1 gelöst.This task is solved by the subject matter of the characterizing part of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß auf einfache Weise eine gegenüber dem Stand der Technik weitere Verminderung der Übertragung von Erschütterungsemissionen erreicht wird, die von schienengebundenen Fahrzeugen ausgeht. Der Materialkostenaufwand wird dabei verkleinert. Die Zerstörungsanfälligkeit des Dämm-Materials beim Reparaturschweißen der Schienen wird weitgehend verhindert weiter vermindert. Der Aufwand zur Verminderung der Erschütterungsimmission, z. B. in Gebäuden, im Boden, kann wesentlich vermindert werden bzw. ganz entfallen.The advantages that can be achieved with the invention are, in particular, that a further reduction in the transmission of vibration emissions compared to the prior art is achieved in a simple manner, which emanates from rail-bound vehicles. The cost of materials is reduced. The susceptibility to destruction of the insulation material during repair welding of the rails is largely prevented. The effort to reduce the vibration immission, e.g. B. in buildings, in the ground, can be significantly reduced or completely eliminated.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Sie zeigt im Querschnitt eine fertig eingegossene Schiene.An embodiment is shown in the drawing. In cross section it shows a cast rail.

Zwischen einem Betonbett 1 und einem Fuß 2, z. B. einer Straßenbahnschiene 3, wird auf bekannte Weise ein Zwischenraum 4 eingestellt. Links und rechts von der Schiene 3 werden in einem Abstand und parallel zu der Schiene 3 vertikale, wieder entfernbare Verschalungen 6, 7 auf das Betonbett 1 aufgesetzt.Between a concrete bed 1 and a foot 2, e.g. B. a tram rail 3, a space 4 is set in a known manner.
