Abstract

The bracket (5) can form one or both sides of the rail (1) and has a horizontal base and one, or two parallel, vertical sides. The base is anchored underneath the rail foot, and the side rises vertically at a distance from the rail. Welded to the top of the vertical member is a holder (3) to which is fixed the sound proof material (4) at a height which masks the line of contact between the rail and wheel (2). Alternatively ,the holder can be an individual raking bracket anchored to the sleeper or to a concrete pad. ADVANTAGE - Physically and optically inconspicuous.

Description

Die Erfindung betrifft eine luftschalldämmende Vorrichtung für Eisenbahnschienen, zur Verhinderung der Luftschallaus­ breitung, bestehend aus einem Metall- oder Kunststoffträger, der ein- oder beidseitig der Schiene befestigt wird, vertikal neben Schienenkopf und Rad aufragt und an seiner schienenzuge­ wandten Seite mit einem luftschallabsorbierenden Material be­ schichtet ist.The invention relates to an airborne soundproofing device for railroad tracks, to prevent airborne noise spread, consisting of a metal or plastic carrier, which is attached to one or both sides of the rail, vertically rises next to the rail head and wheel and on its rail train side with an airborne sound absorbing material is layered.

Als Schallschutzmaßnahmen werden im Bereich des Schienenver­ kehrs bisher körperschalldämmende Vorrichtungen an der Schiene selbst bzw. der Schienenanlage an- oder eingebaut, z. B. Pa­ tentschrift DE 37 22 439 C 2. Gegen den von Schienenfahrzeu­ gen im Betrieb ausgehenden Luftschall werden in der Regel Schallschutzwände aufgestellt, die aufgrund des notwendigen Abstandes von der Schallquelle eine bestimmte Höhe und damit auch Konstruktionsstärke benötigen. Die Aufstellung dieser raumbeanspruchenden und optisch auffälligen Luftschall­ schutzvorrichtungen ist aus baulichen, planerischen oder ge­ stalterischen Gründen häufig nicht möglich.As noise protection measures in the area of rail Kehrs previously structure-borne noise-reducing devices on the rail itself or the rail system attached or installed, e.g. B. Pa tentschrift DE 37 22 439 C 2. Against that of rail vehicles Airborne noise emitted during operation is usually reduced Soundproof walls erected due to the necessary Distance from the sound source a certain height and thus also need construction strength. The listing of this space-consuming and visually striking airborne sound Protective devices are of structural, planning or ge design reasons often not possible.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, den beim Betrieb von Schienenfahrzeugen ausgehenden Luftschall durch räumlich und optisch weniger auffällige Maßnahmen in unmittelbarer Nähe der Schallquelle zu verringern und an ei­ ner Ausbreitung in die Umgebung des Gleiskörpers zu hindern.In contrast, the invention is based on the object Airborne sound emitted when operating rail vehicles through spatially and optically less noticeable measures in close proximity to the sound source and to egg prevent spreading into the vicinity of the track body.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein- oder beidseitig der Schiene, unmittelbar neben der Kontaktflä­ che zwischen Rad und Schiene als wesentlicher Geräuschquelle, ein Metall- oder Kunststoffträger (Luftschallschürze) an­ geordnet wird, der über die Schienenoberkante hinausragt. Durch diese Anordnung wird der Luftschall bereits in direkter Nähe beim Emissionsort an seiner Ausbreitung in die Umgebung gehindert. Das Trägerelement ist außerhalb des vom bewegten Rad in Anspruch genommenen Raumes befestigt und wird auf der schienenzugewandten Seite mit einem aufgeklebten oder aufvul­ kanisierten Absorptionsmaterial beschichtet. Hierdurch wird eine effektive luftschalldämmende Wirkung erreicht. Die schallpegelmindernde Wirkung ist von den geometrischen Ab­ ständen zwischen Emissionsort und Beugungskante des Träger­ elementes und dessen höhenmäßiger Ausdehnung in den Bereich des Rades abhängig.This object is achieved in that or on both sides of the rail, directly next to the contact surface surface between wheel and rail as an essential source of noise, a metal or plastic support (airborne sound apron) is arranged, which protrudes beyond the top edge of the rail. With this arrangement, the airborne sound is already more direct Proximity to the point of emission at its spread into the environment hindered. The carrier element is outside of the moving Wheel attached takes up space and is on the rail-facing side with a glued or bulged coated absorbent material. This will  achieves an effective airborne sound insulation effect. The sound level reducing effect is from the geometric Ab between the emission location and the diffraction edge of the beam element and its height expansion in the area dependent on the wheel.

Die Befestigung der Trägerelemente an der Schiene erfolgt über entsprechend ausgebildete Halterungen. Zur Erzielung ei­ nes optimalen Lärmschutzes kann die Schallschürze als gemein­ sames Bauteil mit bereits bestehenden Absorptionskörpern, die mittels Federelementen in die Laschenkammern der Schiene ein­ gespannt werden, hergestellt werden.The support elements are attached to the rail via appropriately trained brackets. To achieve ei For optimal noise protection, the acoustic apron can be considered common same component with existing absorption bodies, the by means of spring elements in the tab chambers of the rail be excited, manufactured.

Konstruktion und Ausführung sind in den Zeichnungen darge­ stellt und werden unter Bezugnahme auf diese wie folgt näher beschrieben. Es zeigt:Construction and execution are shown in the drawings provides and will be described with reference to these as follows described. It shows:
