Description
Keramische Raumauskleidung Die Erfindung betrifft eine keramische Raumauskleidung, insbesondere Tunnelauskleidung, gebildet von Keramikplatten. Ceramic Room Lining The invention relates to a ceramic Room lining, in particular tunnel lining, formed from ceramic plates.
Keramische Raumauskleidungen, insbesondere von Naßräumen und auch von Tunnels sind boannt. Es ist auch bekannt, zur Raumauskleidung keramische Hohlplatten mit inneren Hohlräumen zu verwenden, von deren freiliegenden Flächen ausgehend Durchbrüche zu den Hohlräumen führen. Mit diesen Durchbrüchen wird, insbesondere, wenn diese mit porösem Material hinterkleidet sind, eine Schallabsorption erreicht, z.B. in Schwimmhallen. Die Schallabsorption besitzt ihr Maximum bei einer bestimmten Frequenz, dia vor. der Zahlt, Größe und Anordnung der Durchbrüche abhängig ist.Ceramic room linings, especially of wet rooms and also of tunnels are blown. It is also known to use hollow ceramic panels for lining rooms to be used with internal cavities with openings starting from their exposed surfaces lead to the cavities. With these breakthroughs, especially if this one are covered with porous material, a sound absorption is achieved, e.g. in Swimming pools. The sound absorption has its maximum at a certain frequency, slide before. depends on the number, size and arrangement of the openings.
Es hat sich gezeigt, daß eine Absorption nit größerer Frequenzbandbreite dadurch erzielt werden kann, daß unterschiedliche Platten gemischt werden, welche sich durch die Zahl und/oder den Querschnitt der Durchbrüche voneinander unterscheiden.It has been shown that an absorption with a larger frequency bandwidth can be achieved by mixing different plates, which through the number and / or the Cross-section of the breakthroughs from each other differentiate.
Demgemäß wird erfindungsgemäß vorgeschlagen, daß die Keramikplatten Hohlplatten mit inneren Itohlrätimen sind, von deren freiliegenden Flächen ausgehend Durchbrüche zu den Hohlraumen führen, und daß unterschiedliche Platten gemischt angeordnet siad, welche sich durch die Zahl und/oder den Querschnitt der Durchbrüche voneinander unterscheiden.Accordingly, the invention proposes that the ceramic plates Hollow slabs with inner planes are based on their exposed surfaces Breakthroughs lead to the cavities, and that different plates mixed arranged siad, which is characterized by the number and / or the cross-section of the openings differ from each other.
Die Hohlplatten können, wie an sich bekannt, Strangpressplatten mit zur St:irangpreasrichtung parallel verlaufenden prismatischen oder zylindrischen Hohlräumen sein.As is known per se, the hollow sheets can also have extruded sheets prismatic or cylindrical running parallel to the direction of the irangpreas Be cavities.
Die vergrößerte Bandbreite der Schallabsorption wird erreicht, gleichgültig, ob die Durchbrüche hinterfllilt sind oder nicht.The increased bandwidth of sound absorption is achieved, no matter whether or not the breakthroughs are backfilled.
Ui ein großes Maß an Schallabsorption zu erreichen, ist es auch bei erfindungsgemäßer Anordnung von Vofteil, wenn die Durchbrüche mit schallabsorbierendem, porösem Material hinterfüllt sind, beispielsweise mit Mineralwolle.In order to achieve a high level of sound absorption, it is also necessary inventive arrangement of Vofteil, if the openings with sound-absorbing, porous material are backfilled, for example with mineral wool.
Die Füllung von Hohlplatten mit porösem Material führt zu Feuchtigkeitsansammlungen in dem porösen Material wenn die Platten DurchbrUche aufweisen. Um ein Ansaugen des porösen Materials mit Feuchtigkeit, insbesondere in Naßräumen zu verhindern wird erfindungsgomaß weiter vorgeschlagen, daß das schallabsorbierende, poröse Material in wasserdichtem Kunststoffoliennateial verpackt ist. Es hat sich gezeigt, daß durch Einschluß des porösen Materials in Kunststoffolien die Schallabsorptionseigenschaften nicht wesentlich verschlechtert werden.The filling of hollow sheets with porous material leads to the accumulation of moisture in the porous material if the plates have breakthroughs. To a suction of the porous material to prevent moisture, especially in wet rooms Invention is further proposed that the sound-absorbing, porous material is packed in waterproof plastic film. It has been shown that through Inclusion of the porous material in plastic films increases the sound absorption properties will not be significantly degraded.
Um die Bildung von Feuchtigkeitsansammlungen in den nicht ausgefüllten Teilen der Hohlräume zu verhindern, kann man die Unterkanten der Durchbrüche in der Einbaustellung der Platten betrachtet bündig mit den tiefstliegenden Begrenzungsflächen 9er Hohlräume legen, so daß das Wasser stets aus den Hohlräumen durch die DurchbrUche herauslaufen kann.To avoid the formation of moisture build-up in the unfilled To prevent the cavities from splitting, you can cut in the bottom edges of the openings the installation position of the panels is flush with the lowest lying boundary surfaces 9 series Lay cavities so that the water always comes out of the cavities through the breakthroughs can run out.
Die Durchbrüche können in Reihen angeordnet sein, wobei Zwischen einander benachbarten Reihen von Durchbrüchen Rippen angeordnet sind, welche über die freiliegende Fläche der Platten vorspringen. Die Rippen tragen ein weiteres bezüglioh des Schallverhaltens der ausgekleideten Räume bei.The openings can be arranged in rows, with between each other adjacent rows of breakthroughs ribs are arranged, which over the exposed Protruding surface of the plates. The ribs bear another aspect of the sound behavior of the lined rooms.
Vorzugsweise wird man die Platten so anordnen, daß die Rippap parallel zum Boden der ausgekleideten Räume verlaufen.The plates will preferably be arranged in such a way that the Rippap is parallel run to the floor of the lined rooms.
Wenn die Hohlplatte von mehreren, parallel verlaufenden, durch Stege voneinander getrennten Hohlräumen durchsetzt ist, so mag die Unterbringung einer gewünschten Gesamtdurchbruchsfläche in der freiliegenden Plattenfläche Schwierigkeiten bereiten. Diese Schwierigkeiten lassen sich dadurch lösen, daß die Durchbrüche länglich oval sind und mit ihren Eauptachsen parallel zur Strangpreßrichtung liegen.If the hollow slab is made up of several, parallel, webs separated cavities is interspersed, so may the accommodation of a desired total breakthrough area in the exposed plate surface difficulties prepare. These difficulties can be solved by making the openings elongated are oval and their main axes are parallel to the extrusion direction.
Es hat sich gezeigt, daß durch Mischung eines ersten Typs von Platten, bei denen die Gesamtdurchbruchsfläche 9 bis 8 der gesamten, freiliegenden Fläche der Platte ausmacht, und eines zweiten Plattentyps, bei denen die Gesamtdurchbruchsfläche 15 bis 30 % der gesamten, freiliegenden Plattenfläche ausmacht, eine Breitbandschallabsorption für die in Fahr-und 3egeh-TunneIs am häufigsten zu erwartenden Schalifrequenzen erreicht wird. Durch Wahl des Mischungsverhältnisses des einen und des anderen Plattentyps kann eine Anpassung an ate Jeweiligen Schallverhältnisse vorgenommen werden.It has been shown that by mixing a first type of plates, where the total breakthrough area 9 to 8 of the total exposed area of the plate, and a second type of plate in which the total opening area 15 to 30% of the total exposed panel surface, broadband sound absorption for the sound frequencies to be expected most frequently in driving and 3-way tunnels is achieved. By choosing the mixing ratio of one and the other type of plate an adaptation to the respective sound conditions can be made.
Optimale Ergebnisse lassen sich erzielen, wonn die Durchbrüche einen Querschnitt von 1 bis 4 cm², vorzugsweise ca.Optimal results can be achieved if the breakthroughs win you Cross-section from 1 to 4 cm², preferably approx.
3 cm² besitzen und gleicbmäßig über die freiliegende Fläche der Platte verteilt aageordnet sind. 3 cm² and the same across the exposed area of the plate are arranged in a distributed manner.

Es stellen dar: Fig. al eine erfindungsgemäße Keramik-Platte, Fig. 2 bis + den Verlauf des Schallabsorptionsgrades in Abhängigkeit von der Frequenz für verschiedene Auskleidungen.The attached figures explain the invention.
