Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Befestigen von Verkleidungsplatten in vorbestimmtem Abstand vor einer Wand.The present invention relates to a device for fastening cladding panels at a predetermined distance from a wall.

Es sind die verschiedensten Befestigungssysteme bzw. Befestigungseinrichtungen bekannt, um Verkleidungsplatten vor Fassaden, Tunnelwänden usw. anzubringen.Various fastening systems or fastening devices are known for attaching cladding panels in front of facades, tunnel walls, etc.

Bei Wandverkleidungen werden einerseits bestimmte Anforderungen an die Platten bzw. deren Beschaffenheit und andererseits Anforderungen an die Befestigung der Platten gestellt, wie beispielsweise leichte Montage durch Personen ohne besondere Fachausbildung, Auswechselbarkeit, Dichtigkeit gegen äußere Einflüsse, wie z.B. Flüssigkeiten (Regen, Spritzwasser).In the case of wall cladding, on the one hand, certain requirements are placed on the panels and their properties and, on the other hand, requirements are placed on the attachment of the panels, such as easy assembly by people without special training, interchangeability, tightness against external influences, e.g. Liquids (rain, splash water).

Es hat sich gezeigt, daß bei hohen Anforderungen an die Befestigungsart recht aufwendige und komplizierte Befestigungskonstruktionen entstehen, die nicht nur einen hohen Beschaffungspreis haben, sondern üblicherweise nur durch speziell ausgebildetes Personal eingesetzt werden können. Auch der eventuelle Austausch und Unterhalt von montierten Platten ist kaum von nichtfachmännischem Personal durchführbar.It has been shown that with high demands on the type of fastening, quite complex and complicated fastening structures arise which not only have a high procurement price, but can usually only be used by specially trained personnel. The eventual replacement and maintenance of assembled panels can hardly be carried out by non-specialist personnel.

Die GB-A-2 018 340 zeigt eine Einrichtung, mit welcher die vertikal verlaufenden Seitenränder von aneinanderstossenden Verkleidungsplatten gehalten werden. Diese Einrichtung lässt nicht erkennen, wie die Platten an der Wand selbst gehalten werden. Die vorliegende Erfindung zeigt jedenfalls eine abweichende Konstruktion.GB-A-2 018 340 shows a device with which the vertically extending side edges are held by abutting cladding panels. This facility does not show how the panels are held on the wall itself. In any case, the present invention shows a different construction.

Aus DE-A-30 34 177 ist eine Befestigungseinrichtung für Verkleidungsplatten in vorbestimmtem Abstand vor einer Wand bekannt, bestehend aus wenigstens einer unteren U-Plattentragschiene und einer oberen, eine Tauchnut bildenden U-Plattenabdeckschiene, welche Schienen mit ihren Nuten sich gegenüberliegend in horizontaler Lage und in der Plattenlänge im wesentlichen entsprechendem Abstand an der zu verkleidenden Wand befestigbar sind, wobei die Platten dank der Tauchnut von vorn in die sich gegenüberliegenden Schienennuten einsetzbar sind; bestehend aus weiteren U-Stützschienen, welche in vertikaler Richtung zwischen den Plattentragschienen und Plattenabdeckschienen mit seitlichen Zwischenabständen, die etwas größer sind als die Breite der zu befestigenden Platten, auf an der Wand angebrachten Befestigungsmitteln befestigbar sind.From DE-A-30 34 177 a fastening device for cladding panels at a predetermined distance from a wall is known, consisting of at least a lower U-plate support rail and an upper U-plate cover rail forming a plunge groove, which rails with their grooves opposite each other in a horizontal position and in the plate length can be attached to the wall to be clad in a substantially corresponding distance, the plates being insertable from the front into the opposite rail grooves thanks to the plunge groove; Consisting of further U-support rails, which can be fastened in the vertical direction between the plate support rails and plate cover rails with lateral spacing, which are slightly larger than the width of the plates to be fastened, on fastening means attached to the wall.

Aufgabe der Erfindung war es somit, eine möglichst einfache, leicht anzuwendende Befestigungsmitteleinrichtung zu finden.The object of the invention was therefore to find a simple, easy-to-use fastener device.

Im Rahmen der Entwicklung einer Befestigungseinrichtung für Tunnelwandverkleidungen, insbesondere im Hinblick auf ein Tunnelsanierungsprojekt, hat sich nun eine Lösung ergeben, welche überraschenderweise die meisten der gestellten Anforderungen in außerordentlich einfacher Weise zu erfüllen vermag. Die Befestigungseinrichtung eignet sich dabei nicht nur für Tunnelverkleidungen, sondern für Verkleidungsplatten schlechthin.As part of the development of a fastening device for tunnel wall cladding, in particular with regard to a tunnel renovation project, a solution has now been found which, surprisingly, is able to meet most of the requirements in an extremely simple manner. The fastening device is not only suitable for tunnel cladding, but for cladding panels par excellence.

Die Befestigungseinrichtung basiert auf jener gemäß DE-A-30 34 177 und zeichnet sich erfindungsgemäß dadurch aus, daß die Platten auf in der Wand anzubringenden Befestigungsbolzen aufsetzbar und mittels Schraubenmuttern an der Wand befestigbar sind, wobei die U-Stützschienen an den äusseren Schenkelenden parallel zum zur Anlage an die Wand gelangenden Zwischensteg verlaufende Stützflächen aufweisen, welche den Wandabstand für die daran zur Anlage gelangenden Platten bestimmen; und daß ferner durch von außen auf die genannten, mit Gewinde versehenen Befestigungsbolzen aufsetzbare und mittels weiterer Schraubenmuttern darauf befestigbare Klemmleisten vorgesehen sind, welche unter Ueberbrückung der offenen Nut der Stützschienen die Platten gegen die Stützflächen dieser Schienen anpressen.The fastening device is based on that according to DE-A-30 34 177 and is characterized according to the invention in that the plates can be placed on fastening bolts to be attached to the wall and fastened to the wall by means of screw nuts, the U-support rails on the outer leg ends parallel to have supporting surfaces which run against the intermediate web which lie against the wall and which determine the distance from the wall for the panels which come against it; and that, in addition, are provided by externally placed on said threaded fastening bolts which can be fastened thereon by means of further screw nuts and which, by bridging the open groove of the support rails, press the plates against the support surfaces of these rails.

Vorzugsweise ist die Breite der Nut der U-Plattentragschiene nur unwesentlich größer als die Höhe der U-Stützschiene plus die Dicke der zu befestigenden Platten, während die Breite der Nut der U-Plattenabdeckschiene größer ist als jene der Plattentragschiene, um als Tauchnut zum Einsetzen der Platten zu dienen. Dies gewährleistet, daß die Platten von vorn zuerst leicht schräg nach oben in die Nut der Plattenabdeckschiene eingeführt, dann der untere Plattenrand nach innen gegen die Stützschiene und nach unten in die Nut der Plattentragschiene eingeführt werden kann. Ein relativ großes Spiel zwischen Stützschiene und Nutenrand braucht somit nur in der Plattenabdeckschiene vorhanden zu sein, damit die Platten über einen bestimmten Weg auch schräg eingeführt werden können.Preferably, the width of the groove of the U-plate support rail is only slightly larger than the height of the U-support rail plus the thickness of the plates to be fastened, while the width of the groove of the U-plate cover rail is larger than that of the plate support rail in order to be used as a plunge groove for inserting the Serve plates. This ensures that the panels are slightly slanted from the front can be inserted upwards into the groove of the plate cover rail, then the lower plate edge can be inserted inwards against the support rail and downwards into the groove of the plate support rail. A relatively large play between the support rail and the groove edge therefore only needs to be present in the plate cover rail so that the plates can also be inserted obliquely in a certain way.

Vorzugsweise sind die Befestigungsbolzen derart ausgebildet, daß sie einen nach der Verankerung frei nach außen abstehenden, mit Schraubgewinde versehenen Abschnitt aufweisen, welcher eine Länge aufweist, die das Befestigen der Stützschiene und der Klemmleiste jeweils mittels Schraubenmuttern auf diesem Abschnitt erlaubt.The fastening bolts are preferably designed in such a way that they have a section which projects freely after the anchoring and is provided with a screw thread and which has a length which permits the fastening of the support rail and the terminal strip in each case by means of screw nuts on this section.

Vorzugsweise sind die U-Stützschienen so ausgebildet, daß sie an den freien Enden der Schenkel jeweils eine Stützfläche für die Platten aufweisen, welche über die ganze Länge des Schenkels verläuft und beidseits des Schenkels von diesem absteht, wobei zwischen den sich gegenüberliegenden Innenlängskanten der beiden Stützflächen jeder Schiene ein Spalt von solcher Breite offengelassen ist, daß die zu seiner Befestigung erforderlichen Schraubenmuttern mit Werkzeug und gegebenenfalls der Verankerungsabschnitt der Klemmleisten von außen einführbar sind.Preferably, the U-support rails are designed so that they each have a support surface for the plates at the free ends of the legs, which runs over the entire length of the leg and protrudes from the leg on both sides, between the opposite inner longitudinal edges of the two support surfaces a gap of such a width is left open for each rail that the nuts required for its fastening can be inserted from the outside with tools and, if appropriate, the anchoring section of the terminal strips.

Die äußere Oberfläche der Stützflächen der Stützschienen kann strukturiert sein, beispielsweise einen rauhen Belag aufweisen, oder mit leicht erhöhten feinen Rippen ausgestaltet sein.The outer surface of the support surfaces of the support rails can be structured, for example have a rough covering, or can be designed with slightly raised fine ribs.

Bei einer besonders geeigneten Ausführungsform sind auch die Klemmleisten als U-Profile ausgebildet, wobei deren freie Schenkel nach innen abgewinkelt sind, um Auflageflächen für die Befestigungsmuttern zu bilden, während der Verbindungssteg seitlich über die Schenkel hinaus verlängert ist, um Anpreßflächen für die Platten zu bilden.In a particularly suitable embodiment, the terminal strips are also designed as U-profiles, the free legs of which are angled inwards in order to form contact surfaces for the fastening nuts. while the connecting web is extended laterally beyond the legs to form contact surfaces for the plates.

Die Klemmleiste weist dabei Öffnungen zum Durchführen der Befestigungsbolzen bzw. der Befestigungsmuttern auf, wobei sich diese vorzugsweise im Verbindungssteg der U-förmigen Profile befinden. Diese Öffnungen sind vorzugsweise mit Verschlußkappen verschließbar.The terminal strip has openings for the passage of the fastening bolts or the fastening nuts, these being preferably located in the connecting web of the U-shaped profiles. These openings can preferably be closed with caps.

Dank der beschriebenen und definierten Befestigungseinrichtung lassen sich Platten beliebiger Länge und Breite, beispielsweise solche einer Länge von 3 m und mehr und einer Breite von 1 m und mehr auf einfachste Weise aneinandergereiht montieren, wobei gleichzeitig die Trennfugen auf optimale Weise abgedichtet sind. Dank der besonderen Ausbildung der Stützschienen und der Befestigungsbolzen lassen sich auch diese Teile vollständig hinter den Plattenwänden bzw. den Klemmleisten unterbringen.Thanks to the described and defined fastening device, panels of any length and width, for example those of a length of 3 m and more and a width of 1 m and more, can be assembled in a very simple manner, while at the same time the separating joints are optimally sealed. Thanks to the special design of the support rails and the fastening bolts, these parts can also be accommodated completely behind the panel walls or the terminal strips.

Die Erfindung wird nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen noch etwas näher erläutert. Es zeigt:

  • Fig. 1 rein schematisch eine Ansicht von in einem Tunnel unter Verwendung einer erfindungsgemäßen Einrichtung angeordneten Verkleidungsplatten;
  • Fig. 2 einen Vertikalschnitt durch eine erfindungsgemäß befestigte Verkleidungsplatte, zum Beispiel entlang der Linie A-A von Fig. 1;
  • Fig. 3 eine rein schematische Ansicht einer Plattentragschiene und einer Plattenabdeckschiene;
  • Fig. 4 einen Horizontalschnitt, etwa entlang der Linie B-B von Fig. 1 durch eine erfindungsgemäß befestigte Plattenreihe; und
  • Fig. 5 eine schematische Ansicht eines in der Wand verankerten Befestigungsbolzens.
The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. It shows:
  • Fig. 1 is a purely schematic view of cladding panels arranged in a tunnel using a device according to the invention;
  • 2 shows a vertical section through a cladding panel fastened according to the invention, for example along the line AA from FIG. 1;
  • 3 shows a purely schematic view of a plate support rail and a plate cover rail;
  • 4 shows a horizontal section, approximately along line BB of FIG. 1, through a row of plates fastened according to the invention; and
  • Fig. 5 is a schematic view of a fastening bolt anchored in the wall.

Fig. 1 der Zeichnung zeigt rein schematisch einen Straßentunnel, dessen Seitenwände in den unteren Abschnitten über eine bestimmte Höhe, beispielsweise über eine Höhe von 3,5 m, mittels Verkleidungsplatten 1 aus säurefestem Material abgedeckt sind. Die Platten 1 sind dabei nebeneinander in einer unteren U-Plattentragschiene 2 und einer oberen, eine Tauchnut bildenden U-Plattenabdeckschiene 3 gehalten. Diese Schienen 2,3 sind in der Tunnelwand auf geeignete Weise festgeschraubt, und die Verkleidungsplatten liegen im Abstand vor der Wand. Auf die Vorteile einer solchen Tunnelwandverkleidung wird weiter unten noch näher eingegangen.Fig. 1 of the drawing shows purely schematically a road tunnel, the side walls of which are covered in the lower sections over a certain height, for example over a height of 3.5 m, by means of cladding panels 1 made of acid-resistant material. The plates 1 are held side by side in a lower U-plate support rail 2 and an upper U-plate cover rail 3 forming a plunge groove. These rails 2, 3 are suitably screwed into the tunnel wall and the cladding plates are spaced from the wall. The advantages of such tunnel wall cladding are discussed in more detail below.

Die nachstehend beschriebene Befestigungseinrichtung für Verkleidungsplatten eignet sich selbstverständlich nicht nur für Verkleidungsplatten für Tunnelwände, sondern für Verkleidungsplatten jeglicher Art.The fastening device for cladding panels described below is of course not only suitable for cladding panels for tunnel walls, but for all types of cladding panels.

Fig. 2 der Zeichnung zeigt einen Vertikalschnitt entlang der Linie A-A von Fig. 1 durch eine Verkleidungsplatte und deren Befestigungseinrichtung.Fig. 2 of the drawing shows a vertical section along the line A-A of Fig. 1 through a cladding panel and its fastening device.

Die eigentliche Befestigungseinrichtung besteht aus einer unteren U-Plattentragschiene 2, einer oberen U-Plattenabdeckschiene 3, jeweils einer U-Stützschiene 4 an den Verbindungstellen zwischen zwei Platten 1, und einer Klemmleiste 5 an jeder dieser Verbindungsstellen, um die eingesetzten Platten 1 dicht und zwischen sich abgedichtet gegen die Stützchiene 4 anzudrücken.The actual fastening device consists of a lower U-plate support rail 2, an upper U-plate cover rail 3, in each case a U-support rail 4 at the connection points between two plates 1, and a terminal strip 5 at each of these connection points, in order to seal the inserted plates 1 tightly and between to press sealed against the support rail 4.

Die Ausgestaltung der Plattentragschiene 2 und der Plattenabdeckschiene 3 geht noch deutlicher aus Fig. 3 hervor. Daraus ist ersichtlich, daß im Verbindungssteg 2c der beiden Schenkel 2a und 2b Öffnungen 2d vorgesehen sind, welche eine Hinterlüftung der später einzusetzenden Platten ermöglichen. Dasselbe gilt für die Plattenabdeckschiene 3, bei welcher ebenfalls zwischen den Schenkeln 3a und 3b im Steg 3c Lüftungsöffnungen 3d vorgesehen sind.The configuration of the plate support rail 2 and the plate cover rail 3 can be seen more clearly from FIG. 3. It can be seen from this that openings 2d are provided in the connecting web 2c of the two legs 2a and 2b, which enable ventilation of the plates to be used later. The same applies to the plate cover rail 3, in which also between the legs 3a and 3b in the web 3c ventilation openings 3d are provided.

Die gezeigten beiden Schienen bestehen vorzugsweise aus Leichtmetall, beispielsweise aus Aluminium und werden in an sich bekannter Weise an der zu verkleidenden Wand befestigt, und zwar mit ihren Nuten sich gegenüberliegend, in horizontaler Lage, wobei der gegenseitige Abstand im wesentlichen der Länge der zu befestigenden Platten entspricht, wobei die Schienen bzw. Profile so ausgestaltet sind, daß die Platten dank der gebildeten Tauchnut von vorn in die sich gegenüberliegenden Schienennuten einsetzbar sind. Dies geht insbesondere aus Fig. 2 hervor.The two rails shown are preferably made of light metal, for example aluminum, and are fastened in a manner known per se to the wall to be clad, with their grooves opposite one another, in a horizontal position, the mutual distance essentially being the length of the plates to be fastened corresponds, wherein the rails or profiles are designed so that the plates can be inserted from the front into the opposite rail grooves thanks to the plunge groove formed. This is particularly evident from Fig. 2.

Daraus ist auch ersichtlich, daß die Breite b1 der Nut der Plattentragschiene nur leicht größer ist, als die Höhe der Stützschienen 4 plus die Dicke der zu befestigenden Platten 1, so daß die Platten 1 zwar leicht hinter den Schenkel 2a einschiebbar, dort jedoch mit wenig Spiel festgehalten sind. Anders verhält es sich bei der Nut der Plattenabdeckschiene 3, deren Breite b2 größer ist als jene der Plattentragschiene, damit sie auch als sogenannte Tauchnut zum Einsetzen der Platten von vorn dienen kann.From this it can also be seen that the width b1 of the groove of the plate support rail is only slightly larger than the height of the support rails 4 plus the thickness of the plates 1 to be fastened, so that the plates 1 can be easily inserted behind the legs 2a, but with little Game are recorded. The situation is different with the groove of the plate cover rail 3, the width b2 of which is greater than that of the plate support rail, so that it can also serve as a so-called plunge groove for inserting the plates from the front.

Die Platten werden von vorn zuerst leicht geneigt nach oben in die Nut der Schiene 3 eingeschoben, dann nach hinten gegen die Stützschiene 4 gelegt und nach unten in die Nut der Schiene 2 eingesetzt. Dabei kommt die Platte 1 schließlich hinter die äußeren Schenkel 2a der Schiene 2 und 3a der Schiene 3 zu liegen und ist somit festgehalten. Das Anpressen der Platten 1 gegen die Stützschienen 4 erfolgt durch andere, nachstehend zu beschreibende Befestigungsmittel.The plates are first inserted at a slight incline upwards into the groove of the rail 3, then placed backwards against the support rail 4 and inserted downwards into the groove of the rail 2. The plate 1 finally comes to lie behind the outer legs 2a of the rail 2 and 3a of the rail 3 and is thus retained. The plates 1 are pressed against the support rails 4 by other fastening means to be described below.

Bei dem in Fig. 2 gezeigten Ausführungsbeispiel besitzt die Plattentragschiene eine nach unten führende Verlängerung 2e, welche ihrerseits eine horizontal verlaufende Längsnut bildet, in welcher beispielsweise ein sogenanntes Abschlußprofil 6 aus flexiblem Material, beispielsweise eine Gummischürze einsetzbar ist, um auch den untersten Teil der Wand zu schützen.In the embodiment shown in Fig. 2, the plate support rail has a downward Extension 2e, which in turn forms a horizontally extending longitudinal groove in which, for example, a so-called end profile 6 made of flexible material, for example a rubber apron, can be used to protect the lowest part of the wall.

Fig. 4 der Zeichnung zeigt einen Horizontalschnitt durch eine erfindungsgemäß befestigte Verkleidungsplattenreihe, beispielsweise entlang der Linie B-B von Fig. 1.FIG. 4 of the drawing shows a horizontal section through a row of cladding panels fastened according to the invention, for example along the line B-B of FIG. 1.

In der rechten Bildhälfte ist anstelle einer weiteren Anschlussplatte 1 ein sogenanntes Abschlußprofil 7 eingesetzt, welches sich, wie ersichtlich, leicht anstelle einer Abdeckplatte einsetzen, bzw. einspannen läßt.In the right half of the figure, a so-called end profile 7 is used instead of a further connection plate 1, which, as can be seen, can easily be inserted or clamped in place of a cover plate.

Aus Fig. 4 geht ebenfalls hervor, daß je nach Breite der Platten 1 eine zusätzliche Stützschiene 8 mit Stützfläche 8ʹ eingesetzt wird, deren Höhe ebenfalls dem verlangten Wandabstand für die Platte 1 entspricht, zwischen jeweils zwei Stützschienen 4 ebenfalls vertikal verlaufend eingesetzt wird.From Fig. 4 also shows that depending on the width of the plates 1, an additional support rail 8 with support surface 8, is used, the height of which also corresponds to the required wall distance for the plate 1, between two support rails 4 is also used vertically.

Aus dieser Darstellung geht hervor, daß die U-Stützschienen 4 an den freien Enden der Schenkel 4a jeweils eine Stützfläche 4b aufweisen, welche vorzugsweise über die ganze Länge der Schiene verlaufen und beidseitig jedes Schenkels 4a von diesem abstehen, wobei zwischen den sich gegenüberliegenden Innenlängskanten 4c der beiden Stützflächen 4b jeder Schiene ein Spalt von solcher Breite offen bleibt, daß der Verankerungsteil der Klemmleisten 5 von außen durchgeführt werden kann. Die Stützschienen 4 sind mittels Befestigungsbolzen 9, welche in der Wand 10 verankert sind, und mittels Schraubmuttern 11 befestigt. Der mit Gewinde versehene äußere Abschnitt des Befestigungsbolzens 9 ist dabei noch wesentlich länger ausgebildet und erstreckt sich bis in den Verankerungsteil der Klemmleiste 5 hinein und dient dort der Befestigung der Klemmleiste ebenfalls durch eine Schraubenmutter 12. Die Klemmleiste 5 besteht im Prinzip aus einer U-Schiene bzw. einem U-Profil, vorzugsweise ebenfalls aus Aluminium wie die Stützschiene 4 und die übrigen Schienen, wobei der Verbindungssteg 5b seitliche Verlängerungen bzw. Verbreiterungen 5c aufweist, welche Anpressflächen für die zu befestigenden Platten 1 bilden.From this representation it can be seen that the U-support rails 4 each have a support surface 4b at the free ends of the legs 4a, which preferably extend over the entire length of the rail and project from each leg 4a on both sides thereof, with 4c between the opposing inner longitudinal edges of the two support surfaces 4b of each rail, a gap of such a width remains open that the anchoring part of the terminal strips 5 can be carried out from the outside. The support rails 4 are fastened by means of fastening bolts 9, which are anchored in the wall 10, and by means of screw nuts 11. The threaded outer section of the fastening bolt 9 is designed to be considerably longer and extends into the anchoring part the terminal strip 5 into it and also serves to fasten the terminal strip by means of a screw nut 12. The terminal strip 5 consists in principle of a U-rail or a U-profile, preferably also made of aluminum like the support rail 4 and the other rails, the Connecting web 5b has lateral extensions or widenings 5c, which form pressing surfaces for the plates 1 to be fastened.

Die freien Schenkel 5a des U-Profils der Klemmleiste 5 sind nach innen abgewinkelt, um Auflageflächen für die Befestigungsmuttern 12 zu bilden. Diese Befestigungsmuttern 12 werden durch runde oder gegebenenfalls ovale Oeffnungen 5d im Steg 5b der Klemmleiste 5 eingeführt. Selbstverständlich werden die Befestigungsbolzen 9 so angeordnet, daß die Schienen 5 mit ihren Öffnungen 5d jeweils an den richtigen Stellen über den Bolzen 9 zu liegen kommen.The free legs 5a of the U-profile of the terminal strip 5 are angled inwards to form contact surfaces for the fastening nuts 12. These fastening nuts 12 are inserted through round or possibly oval openings 5d in the web 5b of the terminal strip 5. Of course, the fastening bolts 9 are arranged in such a way that the rails 5 with their openings 5d each come to lie at the correct points over the bolts 9.

Aus der vorstehenden Beschreibung geht hervor, wie mit einfachsten Mitteln eine Befestigungseinrichtung für Verkleidungsplatten erstellt werden kann, welche es auch Personen ohne besondere Fachkenntnisse erlaubt, solche Platten einzusetzen, bzw. auszuwechseln. Das besonders Raffinierte an der Konstruktion liegt zweifelsohne in der besonderen Ausbildung von Stützschiene 4 und Klemmleiste 5, welche zusammen das dichte Festmachen der Platten 1 auf nur wenigen Befestigungsbolzen 9 erlaubt, da diese gleichzeitig zur Befestigung der Stützschienen 4 und der Klemmleisten 5 dienen. Die in den Klemmleisten 5 vorgesehenen Montageöffnungen 5d können durch Pfropfen aus Gummi oder Kunststoff abgedeckt werden, um die dahinter angeordneten Konstruktionsteile, wie beispielsweise Befestigungsbolzen, Schraubenmuttern uzw. vor schädlichen Einflüssen zu schützen.From the above description it can be seen how the simplest means can be used to create a fastening device for cladding panels, which also allows people without special expertise to use or replace such panels. What is particularly refined about the construction is undoubtedly the special design of the support rail 4 and the terminal strip 5, which together allows the plates 1 to be tightly fastened to only a few fastening bolts 9, since these serve at the same time for fastening the support rails 4 and the terminal strips 5. The mounting openings 5d provided in the terminal strips 5 can be covered by rubber or plastic plugs in order to use the structural parts arranged behind them, such as fastening bolts, screw nuts, etc. to protect against harmful influences.

Fig. 5 der Zeichnung zeigt noch ein Detail der Verankerung der Befestigungselemente 9 in der Wand 10. Selbstverständlich sind auch andere Befestigungsbolzen als die gezeigten denkbar.5 of the drawing shows a detail of the anchoring of the fastening elements 9 in the wall 10. Of course, fastening bolts other than those shown are also conceivable.

Wie bereits erwähnt, wurde die beschriebene Befestigungseinrichtung im Rahmen der Suche nach neuen Lösungen zur Befestigung von Verkleidungsplatten in Tunnels gefunden. Es hatte sich gezeigt, daß die vorzugsweise aus Beton oder mit Betonverkleidungen ausgestalteten Tunnelwände durch äußere Einwirkungen, insbesondere durch Einwirkung von Streusalz über eine bestimmte Höhe ab Boden (bis zu einer Höhe von ca. 2,5 m) große Schäden aufwiesen, wie beispielsweise Spannungsrisse infolge Feuchtigkeitseinwirkung etc.As already mentioned, the fastening device described was found in the search for new solutions for fastening cladding panels in tunnels. It had been shown that the tunnel walls, which were preferably made of concrete or with concrete cladding, were severely damaged by external influences, in particular by the action of road salt above a certain height from the ground (up to a height of approximately 2.5 m), such as stress cracks due to exposure to moisture etc.

Eine Lösung des Problems bestand im Anbringen von Verkleidungsplatten, wobei folgende Kriterien zu beachten waren:

  • Reduktion der Salzangriffe auf Wände
  • Lösung muß dauerhaft sein
    (Beachtung der klimatischen Besonderheiten)
  • Schnelle rationnelle Montage durch regionale Firmen
    (Arbeitsbeschaffung)
  • Beschädigungen müssen rasch repariert werden können
    (durch Strassenunterhaltungsdienst, ohne spezielle Kenntnisse)
  • preislich sehr gutes Kosten/Nutzenverhältnis
  • qualitativ hochwertige Produkte und Materialien
  • hinterlüftetes System und dadurch optimaler Betonschutz
  • ästhetische Aufwertung (ev. durch Farbenspiel) von Tunnelwänden
  • Fahrverhalten darf nicht gestört werden
One solution to the problem was to attach cladding panels, taking the following criteria into account:
  • Reduction of salt attacks on walls
  • Solution must be permanent
    (Attention to the climatic peculiarities)
  • Fast, rational installation by regional companies
    (Job creation)
  • Damages must be repaired quickly
    (by street entertainment service, without special knowledge)
  • very good value for money
  • high quality products and materials
  • ventilated system and therefore optimal concrete protection
  • aesthetic enhancement (possibly through play of colors) of tunnel walls
  • Driving behavior must not be disturbed

Die zu verwendenden Materialien müssen gegen folgende Einflußfaktoren geschützt oder resistent sein:

  • Salzangriffe
  • Abgasgemische
  • extreme Temperaturschwankungen
  • Feuchtigkeitsschwankungen
  • Windeinflüsse
  • Feuerangriff
  • mechanische Angriffe
  • unbekannte Faktoren
The materials to be used must be protected or resistant to the following factors:
  • Salt attacks
  • Exhaust mixtures
  • extreme temperature fluctuations
  • Fluctuations in humidity
  • Wind influences
  • Fire attack
  • mechanical attacks
  • unknown factors

Nach Installation der Verkleidungsplatten muß die Funktionstüchtigkeit aufrechterhalten bleiben, was durch Hilfskräfte und Service-Personal möglich sein muß. Einfachheit, Verwendung nur weniger Spezialwerkzeuge und problemloses Auswechseln von beschüdigten Teilen sind die Hauptkriterien für einen optimalen Service.After installing the cladding panels, the functionality must be maintained, which must be possible by assistants and service personnel. Simplicity, the use of only a few special tools and easy replacement of damaged parts are the main criteria for optimal service.

Die erfindungsgemäße Konstruktion einer Befestigungseinrichtung erfüllt im wesentlichen alle diese Kriterien. Von besonderer Wichtigkeit ist, daß die eigentlichen Verkleidungsplatten befestigt bzw. festgeklemmt sind, ohne daß Befestigungsmittel wie Schrauben und dergleichen durch diese Platten selbst führen. Die Platten sind auf äußerst einfache Weise einzusetzen, bzw. auszutauschen.The construction of a fastening device according to the invention essentially meets all of these criteria. It is of particular importance that the actual cladding panels are attached or clamped without fasteners such as screws and the like leading through these panels themselves. The plates are extremely easy to use or replace.

Als Verkleidungsplatten eignen sich insbesondere "Stenex"-Fassadenplatten. Es handelt sich dabei um großflächige Fassadenplatten, bestehend aus glasfaserverstärktem Polyester mit Quarzsandfüllung. Die Oberfläche besteht aus einer qualitativ hochwertigen Deckschicht, welche beliebig einfärbbar ist. Die Platten lassen sich problemlos biegen und sind somit auch im Rundungsbereich von Tunnelwänden anwendbar."Stenex" facade panels are particularly suitable as cladding panels. These are large-scale facade panels consisting of glass fiber reinforced polyester with quartz sand filling. The surface consists of a high quality top layer, which can be colored as desired. The plates can be bent without any problems and can therefore also be used in the rounded area of tunnel walls.

Die Profile hinter den Platten sind nach der Montage an sich geschützt und brauchen nicht besonders behandelt zu werden. Die Platten und Klemmleisten werden auf geeignete Weise beschichtet, falls die äußeren Einflüsse dies erfordern.The profiles behind the panels are protected per se after installation and do not need special treatment. The plates and terminal strips are coated in a suitable manner if the external influences so require.
