Abstract
Die Erfindung betrifft eine Lärmschutzwand mit einem tragenden Wandteil aus Tragbeton und einer keramischen Vorsatzschale oder dergleichen als Schallabsorptions-Schicht, bei der die Schallabsorptions-Schicht aus gebrannten Blähton-Körpern und einem Bindemittel besteht. DOLLAR A Die Erfindung ist dadurch gekennzeichnet, dass der überwiegende Teil der Blähton-Körper (7) eine einheitliche Körnung besitzt.The invention relates to a noise barrier with a supporting wall portion of supporting concrete and a ceramic facing shell or the like as a sound absorption layer in which the sound absorption layer consists of fired expanded clay bodies and a binder. DOLLAR A The invention is characterized in that the majority of the expanded clay body (7) has a uniform grain size.
Description
Die Erfindung betrifft eine Lärmschutzwand mit einem tragenden Wandteil aus Tragbeton und einer keramischen Vorsatzschale oder dergleichen als Schallabsorptions-Schicht.The The invention relates to a noise barrier with a load-bearing wall section made of supporting concrete and a ceramic facing shell or the like as a sound absorption layer.
Es sind Lärmschutzwände bekannt, bei denen die Schallabsorptions-Schicht aus zementgebundenen Holzspänen besteht.It are noise barriers known in which the sound absorption layer consists of cement-bound wood chips.
Nachteilig bei diesen bekannten Lärmschutzwänden ist, dass die Langzeit-Festigkeit der Schallabsorptions-Schicht durch den ständigen Feuchtigkeitswechsel der zementgebundenen Holzspäne leidet. Außerdem sind die Zwischenräume zwischen den Holzspänen sehr unterschiedlich groß, so dass die von diesen Zwischenräumen gebildeten Schallkanäle nicht – oder nur sehr gering – dem zu absorbierenden Schall angepasst werden können.adversely in these known noise barriers, that the long-term strength of the sound absorption layer through the constant change of humidity the cement-bound wood chips suffers. Furthermore are the spaces between the wood chips very different sizes, so that of these spaces formed sound channels Not or only very low - the can be adapted to absorb sound.
Die Aufgabe der Erfindung ist, diese bekannten Nachteile zu vermeiden, und eine Lärmschutzwand zu offenbaren, bei der die Langzeit-Festigkeit der Schallabsorptions-Schicht praktisch unbegrenzt konstant bleibt.The The object of the invention is to avoid these known disadvantages, and a noise barrier reveal the long-term strength of the sound absorption layer practically unlimited remains constant.
Außerdem sollen die Schallkanäle der Schallabsorptions-Schicht sehr genau dem zu absorbierenden Schall angepasst werden können.In addition, should the sound channels the sound absorption layer very exactly the sound to be absorbed can be adjusted.
Zu diesem Zweck ist die Erfindung durch die in den Ansprüchen genannten Merkmale gekennzeichnet.To For this purpose the invention is characterized by what is stated in the claims Characteristics marked.
Mehrere Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt.Several embodiments The invention are shown schematically in the drawings.
