Abstract

Bei einer als Unterlage für eine Schotterbettung dienenden Matte (1) aus elastischem Werkstoff, deren Oberseite mit einer Schicht (2) versehen ist, die aus einem anderen Werkstoff als die Matte (1) besteht, ist die Schicht (2) an der Oberseite der Matte (1) aus einem Vlies gebildet.In the case of a mat (1) made of elastic material, which serves as a base for ballast bedding, the upper side of which is provided with a layer (2) made of a different material than the mat (1), the layer (2) is on the upper side of the Mat (1) formed from a fleece.

Description

Die Erfindung betrifft eine als Unterlage für eine Schotterbettung dienende Matte aus elastischem Werkstoff, deren Oberseite eine Schicht aufweist, .die aus einem anderen Werkstoff als die Matte besteht. Derartige Matten dienen dazu, die Schotterbettung und die darauf verlegten Geleise gegen den Untergrund und gegen Tunnel- oder Trogwände elastisch.zu lagern, um eine Dämmung des Körperschalls zu bewirken.The invention relates to a mat of elastic material which serves as a base for ballast bedding, the upper side of which has a layer which consists of a different material than the mat. Such mats are used to elastically store the ballast bedding and the tracks laid thereon against the ground and against tunnel or trough walls in order to insulate structure-borne noise.

Bei einer bekannten Matte der vorgenannten Art ist an der Oberseite eine Schicht aus einem plastisch verformbaren Werkstoff vorgesehen (DE-GM 80 13 779), z. B. eine Bitumenschicht. In diese Schicht können sich die Schottersteine in gewissem Umfang eindrücken, so daß eine weitgehend rutschfeste-Ablagerung erreicht wird. Der wesentliche Nachteil dieser bekannten Matte besteht darin, daß der scharfkantige Schotter in kurzer Zeit auch in die Matte selbst eindringt, wodurch die Matte derart zerstört wird, daß sie schließlich nur noch in granulierter Form vorhanden ist. Eine granulierte Matte vermag aber keinen Körperschall mehr zu dämmen.In a known mat of the aforementioned type, a layer of a plastically deformable material is provided on the top (DE-GM 80 13 779), for. B. a bitumen layer. The gravel stones can be pressed into this layer to a certain extent, so that a largely non-slip deposit is achieved. The main disadvantage of this known mat is that the sharp-edged ballast also penetrates into the mat itself in a short time, as a result of which the mat is destroyed in such a way that it is finally only present in granular form. A granulated mat is no longer able to insulate structure-borne noise.

Eine andere bekannte Matte weist an der Oberseite ein Blech auf (DE-OS 31 21 946), das dazu dient, ein Eindringen des Schotters in die Matte zu verhindern. Diese Matte gewährleistet zwar eine besonders hohe Körperschalldämmung; sie ist aber wenig biegsam, so daß sie nur in verhältnismäßig kurzen Längen an den Einsatzort gebracht werden kann.Another known mat has a sheet on the top (DE-OS 31 21 946), which serves to prevent the ballast from penetrating into the mat. This mat ensures a particularly high structure-borne sound insulation; but it is not very flexible, so that it can only be brought to the place of use in relatively short lengths.

Der Erfindung liegt die Aufgabe zugrunde, die Matte der eingangs genannten Art so auszubilden, daß sie eine ausreichende Körperschalldämmung=gewährleistet, daß sie das Eindringen von Schottersteienen verhindert und daß sie aufwickelbar ist, so daß sie in großen Längen auch an enge Einsatzorte gebracht werden kann. Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst.The invention has for its object to design the mat of the type mentioned so that it = adequate structure-borne sound insulation = ensures that it prevents the penetration of gravel stones and that it can be wound up so that it can be brought in great lengths to narrow locations . This object is achieved by the invention specified in claim 1.

Das an der Oberseite der Matte vorgesehene Vlies erlaubt darüber hinaus eine Einstellung des Überhöhungsgrades der Resonanzfrequenz, und zwar durch die Art des Vlieses und deren Anordnung in der Matte. Dadurch kann eine den jeweiligen Erfordernissen entsprechende Dämmung des Körperschalls durch die Matte herbeigeführt werden.The fleece provided on the top of the mat also allows the degree of exaggeration of the resonance frequency to be adjusted, specifically by the type of fleece and its arrangement in the mat. As a result, the structure-borne noise can be insulated through the mat in accordance with the respective requirements.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous embodiments of the invention are described in the subclaims.

Die Erfindung ist anhand der Zeichnung näher erläutert, in der ein Ausschnitt aus einer Matte im Querschnitt dargestellt ist.The invention is explained in more detail with reference to the drawing, in which a section of a mat is shown in cross section.

Die in der Zeichnung dargestellte Matte 1 ist an ihrer Oberseite mit einer aus einem zweilagigen Vlies gebildeten Schicht 2 versehen, wobei zwischen den einzelnen Lagen des die Schicht 2 bildenden Vlieses eine Einlage 3 aus elastischem Werkstoff vorgesehen ist. Oberhalb der aus einem zweilagigen Vlies gebildeten Schicht 2 ist eine Deckplatte 4 aus elastischem Werkststoff vorgesehen, deren Dicke d etwa halb so groß ist wie die Dicke D der Einlage 3.The mat 1 shown in the drawing is provided on its top with a layer 2 formed from a two-layer fleece, an insert 3 made of elastic material being provided between the individual layers of the fleece forming the layer 2. Above the layer 2 formed from a two-layer fleece, a cover plate 4 made of elastic material is provided, the thickness d of which is approximately half the thickness D of the insert 3.
