Description

Technisches GebietTechnical field

Die Erfindung betrifft Tunnelverkleidungen, die sowohl feuerbeständig als auch schallabsorbierend sind.The invention relates to tunnel cladding that is both fire resistant are also sound absorbing.

Verkehrstunnelbauwerke müssen an den Innenflächen mit schallabsorbierenden Materialien verkleidet werden, um ein Aufschaukeln des Verkehrslärms im Tunnel zu einem unerträglichen Schallpegel zu verhindern. Bei Tunnelbauwerken, die nicht für den Personenverkehr genutzt werden, sind Schallschutzmaßnahmen zwar nicht im gesamten Tunnel erforderlich, jedoch müssen die Aus- und Einfahrrampen zur Eindämmung der Schallemissionen mit schallabsorbierendem Material verkleidet werden.Traffic tunnel structures must be sound-absorbing on the inner surfaces Materials are disguised to increase the traffic noise in the To prevent tunnels from becoming unbearable. For tunnel structures, that are not used for passenger traffic are noise protection measures not required in the entire tunnel, but must the entry and exit ramps to contain noise emissions sound absorbing material.

Gerade Brandkatastrophen in Tunnelbauwerken haben gezeigt, daß in Tunnelröhren, abgesehen von verstärktem aktiven Brandschutz für die Benutzer zukünftig auch der passive Brandschutz des Tunnelbauwerks selbst von allergrößter Bedeutung ist. Nur so können nach einem Brand in einem Tunnel irgendwelche Brandschutzverkleidungen bei Erfordernis sehr kurzfristig ausgetauscht und der Tunnel nach einer solchen Katastrophe schnell wieder in Betrieb genommen werden.Fire disasters in tunnel structures in particular have shown that in tunnel tubes, apart from increased active fire protection for the users In the future, passive fire protection of the tunnel structure itself will also be of the greatest size Meaning is. This is the only way any can after a fire in a tunnel Fire protection cladding can be replaced at very short notice if required and the tunnel quickly back in after such a disaster Be put into operation.

Stand der TechnikState of the art

Es ist bekannt, Verkleidungsplatten als gelochte und gefalzte Aluminiumbleche auszuführen, die mit einer im Brandfall selbstaufschäumenden Beschichtung ausgerüstet sind.It is known to have cladding panels as perforated and folded aluminum sheets to be carried out with a self-foaming coating in the event of fire are equipped.

Aus der DE 32 38 640 C2, der DE 41 02 266 C1 und der DE 196 29 849 A1 ist es bekannt, in Gruben oder Tunneln mattenförmige Bewehrungen auf den Wänden anzubringen und darauf Spritzbeton aufzubringen.From DE 32 38 640 C2, DE 41 02 266 C1 and DE 196 29 849 A1 It is known to use mat-like reinforcements in pits or tunnels Attach walls and spray concrete on them.

Aus der DE 85 21 802 U1 ist ein Glasfaserbetonelement für eine Lärmschutzwand bekannt, daß aus zwei U-förmigen mit Löchern versehenen Schalen besteht, die einen Hohlkasten bilden in dem sich schalldämmende Materialien befinden. Die Herstellung und Aufstellung eines solchen Lärmschutzwandelementes ist aufwendig und schränkt das Lichtraumprofil des Tunnels erheblich ein. DE 85 21 802 U1 describes a glass fiber concrete element for a noise barrier known that from two U-shaped holes Shells exist that form a hollow box in the sound-absorbing Materials. The manufacture and installation of such a noise barrier element is complex and limits the clearance profile of the Tunnels significantly.

Aufgabe der Erfindung ist es, eine platzsparende, leicht austauschbare feuerbeständige und schallabsorbierende Tunnelverkleidung anzugeben.The object of the invention is a space-saving, easily replaceable fire-resistant and sound-absorbing tunnel cladding.

Darstellung der ErfindungPresentation of the invention

Die Erfindung wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.The invention is indicated by the characterizing part of claim 1 Features resolved.

Wesentliches Merkmal hierbei ist die Verwendung einer feuerbeständigen textilbewehrten Betonschale. (Bewehrung bevorzugt aus Textilmatten, nicht aus einzelnen Fasern.)An essential feature here is the use of fire-resistant textile-reinforced Concrete shell. (Reinforcement preferably made of textile mats, not made of individual fibers.)

Diese Schale weist Lochungen auf, durch die der auftreffende Schall in eine dahinterliegende schallabsorbierende Matte, bevorzugt Steinwolle, hindurchtreten kann.This bowl has perforations through which the incident sound into one step behind the sound-absorbing mat, preferably rock wool can.

Die dünne Betonlochschale, die z. B. auch aus Spritzbeton bestehen kann, weist aussteifende Rippenaufkantungen auf, die bevorzugt ebenfalls textilmattenbewehrt sind.The thin concrete perforated shell, the z. B. can also consist of shotcrete, has stiffening rib edging, which is also preferably reinforced with textile mats are.

Bevorzugt sind in diese Rippenaufkantungen bereits die feuerbeständigen Aufhängevorrichtungen zur Aufhängung an den Tunnelwänden und -decken mit eingegossen. Die Aufhängungen können z. B. als feuerbeständige Textilbewehrungsschlaufen ausgestaltet sein, die an der Tunneldecke oder der Tunnelwand in vorgedübelte Edelstahlbefestigungen mit feuerfester Abdekkung eingehängt werden.The fire-resistant are already preferred in these ribs upstands Hanging devices for hanging on the tunnel walls and ceilings poured in. The suspensions can e.g. B. as fire-resistant textile reinforcement loops be designed on the tunnel ceiling or the Tunnel wall in pre-dowelled stainless steel fastenings with fire-proof cover be hung up.

Die hinter den Lochungen befindliche schallabsorbierende feuerbeständige Matte weist bevorzugt einen Verbund zum Beton auf. Entweder sie wird mit einem bevorzugt nicht brennbaren Kleber auf die schon feste Schale aufgeklebt, oder sie wird in den noch frischen Beton eingedrückt. Der Verbund zwischen Betonschale und schallabsorbierender Matte erleichtert die Montage der Tunnelverkleidung.The sound-absorbing fire-resistant behind the perforations Mat preferably has a bond to the concrete. Either she will join a preferably non-flammable adhesive is glued to the already solid shell, or it is pressed into the still fresh concrete. The bond between Concrete shell and sound absorbing mat make assembly easier the tunnel cladding.

Um die Hitzebelastung der zu schützenden Tunnelwandung weiter zu verringern, kann auf der Rückseite der schallabsorbierenden Matte eine ungelochte Schale angebracht sein, die den Durchzug heißer Gase bis zur Tunnelwandung behindert. Diese Schale ist gleichzeitig auch ein Temperaturschutz für die Aufhängung der Tunnelverkleidung.To further reduce the heat load on the tunnel wall to be protected, can be an unperforated on the back of the sound absorbing mat Shell be attached, the passage of hot gases to the tunnel wall with special needs. This bowl is also a temperature protection for the suspension of the tunnel cladding.

Im Gegensatz zum gelochten Aluminiumblech ist die erfindungsgemäße Konstruktion absolut unbrennbar, da die Teile, aus denen sie besteht, bereits voll durchoxidiert sind (alles Oxide von Elementen in ihrer höchsten beständigen Oxidationsstufe) oder durch die Ummantelung mit Beton vom Sauerstoffzufluß abgeschnitten sind. In contrast to the perforated aluminum sheet, the construction according to the invention is absolutely non-flammable since the parts that make it up are already full are fully oxidized (all oxides of elements in their highest resistance Oxidation level) or by covering with concrete from the oxygen inflow are cut off.

Freiliegendes Aluminium kann hingegen ab einer bestimmten Temperatur bei Gegenwart von Sauerstoff extrem exotherm abbrennen (ähnlich wie Magnesium)!Exposed aluminum, on the other hand, can start at a certain temperature Burn off the presence of oxygen extremely exothermally (similar to magnesium)!

Die Textilmatten können als Gewebe, aber auch als Vlies eingesetzt werden. Bevorzugtes Material für die Textilmatten sind nicht brennbare Fasern (Glasfasern, Aluminiumoxidfasern, oder zugfeste Fasern aus anderen Oxiden oder Mischungen von Oxiden per Elemente der 2., 3., 4. oder 5. Haupt- oder Nebengruppe des Periodensystems der Elemente),
aber auch schwer entflammbare Fasern (Kohlenstofffasern, Aramidfasern, Fasern aus den Nitriden oder Mischungen von Nitriden der Elemente der 3., 4. oder 5. Haupt- oder Nebengruppe,).The textile mats can be used as fabrics, but also as fleece. Preferred materials for the textile mats are non-combustible fibers (glass fibers, aluminum oxide fibers, or tensile fibers from other oxides or mixtures of oxides per elements of the 2nd, 3rd, 4th or 5th main or sub-group of the periodic table of the elements),
but also flame-retardant fibers (carbon fibers, aramid fibers, fibers from the nitrides or mixtures of nitrides of the elements of the 3rd, 4th or 5th main or subgroup,).

Auch Fasern, die sich bei Erhitzen unter Luftabschluß (im Inneren des Betons) in schwer entflammbare oder unbrennbare zugfeste Fasern umwandeln, wie z. B. Polyacrylnitrilfasern (Endstufe ist die Kohlenstofffaser), sind als Bewehrung prinzipiell verwendbar.Also fibers that are exposed to heat when sealed in the absence of air (inside the concrete) convert into flame-retardant or non-flammable tensile fibers, such as e.g. B. polyacrylonitrile fibers (the final stage is the carbon fiber) are used as reinforcement usable in principle.

Auswahlkriterium ist auch ein möglichst hoher Schmelz- oder Erweichungspunkt der Fasern, bzw. dessen,was durch Hitzeeinwirkung erst entsteht (mehr als 500 Grad Celsius, bevorzugt mehr als 800 Grad Celsius, noch besser sind mehr als 1000 Grad Celsius).The selection criterion is also the highest possible melting or softening point the fibers, or what is only created by exposure to heat (more than 500 degrees Celsius, preferably more than 800 degrees Celsius, are even better more than 1000 degrees Celsius).

Im folgenden wird ein bevorzugtes Verfahren zur Herstellung der Tunnelverkleidung beschrieben:

  • 1. Auf langen Herstellbahnen in Endlosausführung werden ca. 33 oder 50 cm breite doppellagige Schalbleche aufgelegt. Auf das untere Schalblech sind spitze Dorne aufgeschweißt, über die dann beliebig strukturierte, gelochte Schalbleche in zweiter Lage gestülpt werden.
  • 2. Auf diese Bodenschalungen wird dann die Textilbewehrung aufgelegt und die Betonschale bevorzugt in Spritzbetonbauweise in einer Stärke von ca. 10 Millimetern mit Spritzautomaten darüber gezogen.
  • 3. Die Mineralwollmatten werden auf diese Lochkegel aufgespießt und in den frischen Beton eingedrückt.
  • 4. Nun kann man gegebenenfalls Seitenschalungen für längsverlaufende Aussteifungsrippen aufklappen. Die Aussteifungsrippen können aber auch schon beim ersten Arbeitsgang aufgesetzt werden.
    Die Seitenschalungen sind mit Nut und Feder und gegebenenfalls mit Verbindungsnoppen zu den Nachbarelementen hin ausgeformt, die dann entsprechende gegensinnige Vertiefungen erhalten müssen.
  • 5. Diese Randschalungen der Aussteifungsrippe bilden zusammen mit der dazwischen eingelegten Mineralwollmatte die Gießrinne für die am Außenrand sehr exakt in Nut-, Feder- und Noppenverbindungen geformten Aussteifungsrippen. Vor dem Vergießen dieser Rinnen mit Beton wird auch dort die Textilbewehrung hochgezogen und entsprechende, beliebig lang gewählte Aufhängeschlaufen, ebenfalls in Form der feuerbeständigen Textilbewehrung, eingelegt. Für die direkte Befestigung können auch Z-förmige Edelstahllaschen eingegossen werden, die einen schuppenförmigen Aufbau der Wand- und Dekkenverkleidung, die untereinander mit den Noppenverbindungen gehalten wird, bei gleichzeitiger verdeckter und damit feuerbeständiger Befestigung mit Edelstahldübeln ermöglichen.
  • 6. Nach dem Erhärten dieser Elemente kann die doppelschalige Unterschalung abgenommen und der"Endlos"strang auf verbaubare Längen (z. B. bis etwa sechs Meter) zersägt und in Kommissionseinheiten, die von gängigen Gabelstaplern hantiert werden können, zusammengestellt werden.
    • A preferred method for producing the tunnel cladding is described below:
  • 1. Approx. 33 or 50 cm wide double-layer formwork sheets are placed on long, continuous production lines. Pointed mandrels are welded onto the lower formwork sheet, over which any structured, perforated formwork sheets are then placed in a second position.
  • 2. The textile reinforcement is then placed on these floor formworks and the concrete shell is preferably drawn in spray concrete construction in a thickness of approx. 10 millimeters with automatic sprayers.
  • 3. The mineral wool mats are impaled on these perforated cones and pressed into the fresh concrete.
  • 4. If necessary, you can now open up side formwork for longitudinal stiffening ribs. The stiffening ribs can also be put on during the first work step.
    The side formwork is formed with tongue and groove and, if necessary, with connecting knobs to the neighboring elements, which must then have corresponding recesses in opposite directions.
  • 5. These edge formwork of the stiffening rib, together with the mineral wool mat inserted in between, form the pouring channel for the stiffening ribs, which are formed on the outer edge very precisely in tongue, groove and stud connections. Before these channels are poured with concrete, the textile reinforcement is also pulled up there and appropriate suspension loops of any length inserted, also in the form of fire-resistant textile reinforcement. For direct fastening, Z-shaped stainless steel brackets can also be cast in, which enable a scale-like structure of the wall and ceiling cladding, which is held together with the stud connections, with concealed and thus fire-resistant fastening with stainless steel dowels.
  • 6. After these elements have hardened, the double-shell formwork can be removed and the "endless" strand can be sawn to installable lengths (eg up to about six meters) and assembled in commission units that can be handled by standard forklift trucks.

    • In einer bevorzugten Ausführungsform soll die textilbewehrte Betonschale mit ihren rückseitig aufgesetzten Aussteifungsrippen ein Flächengewicht von 50 Kilogramm pro Quadratmeter möglichst nicht überschreiten. Dies ist auch erreichbar, wenn die Spritzbetonschale mit einer Stärke von ca. 10 Millimetern ausgeführt wird.In a preferred embodiment, the textile-reinforced concrete shell is also to be used the stiffening ribs on the back have a basis weight of 50 If possible, do not exceed kilograms per square meter. This is also achievable if the shotcrete shell with a thickness of about 10 millimeters is performed.

    Die Fig. 1 zeigt im Schnitt ein Ausführungsbeispiel der erfindungsgemäßen Tunnelverkleidung, in diesem Beispiel ohne rückwärtige, geschlossene Platte. Fig. 1 shows in section an embodiment of the invention Tunnel cladding, in this example without a closed rear panel.
