Abstract

A metallic ceiling lining consists of a supporting grid of longitudinal struts (2) and transverse struts (4) and cassettes (6) arranged in the grid compartments. The longitudinal struts (2) and transverse struts (4) have longitudinal projections (26) with a seal (44) arranged on either side at their lower ends. The cassettes () rest in a gastight manner on the projections and the longitudinal struts (2) are designed as essentially rectangular hollow profiles. To permit the attachment of ancillary devices such as lights or partitions without impairing the gastightness of the ceiling lining, the hollow profile is designed as a closed duct (124) and the longitudinal strut (2) also has a region of tubular cross-section (128) for mounting suspended elements (14). The invention is applicable to all types of gastight ceiling linings.

Gas- und staubdichte Deckenverkleidungen aus Metall werden vorzugsweise verwendet, um Räume im klinischen Bereich, im Laborbereich oder Reinsträume von Fertigungsstätten im Deckenbereich gasdicht abzudichten. Da es sich hierbei vielfach um sehr große Deckenflächen handelt, ist es zum einen erforderlich, daß eine ausreichende Gasdichtigkeit gewährleistet ist, zum anderen muß die Deckenverkleidung hohen optischen Anforderungen gerecht werden können.Gas- and dust-tight metal ceiling claddings are preferably used to seal rooms in the clinical area, in the laboratory area or clean rooms of manufacturing facilities in the ceiling area.

A possibility, It is not possible to add attachments to these mounting rails without affecting the tightness.

Aus dem deutschen Gebrauchsmuster DE-U-85 07 324 ist ferner eine Unterdeckenkonstruktion bekannt, die aus sich kreuzenden Tragschienen mit im wesentlichen U-förmigem Profil besteht, daß nach unten offen ist und am unteren Ende der offenen Schenkel horizontal nach außen stehende Vorsprünge für die Auflagerung der Deckenelemente aufweist.
Bei dieser Unterdeckenkonstruktion erweist es sich als nachteilig, daß beim Aufbau eine Reihe von speziellen Anpassungsarbeiten vorgenommen werden müssen, um eine mit den Tragschienen bündige geschlossene Deckenfläche zu erzielen. Durch die nach unten offenen U-Profile ist es z. B. notwendig, spezielle Abdeckschienen einzubringen. Die Dichtungsstreifen für die Deckenelemente müssen mit den seitlichen Vorsprüngen der Tragschienen verklebt werden. Dies alles bedeutet, daß der Aufbau der Unterdeckenkonstruktion relativ kompliziert und nur für einmalige Dauereinbauten, nicht aber für häufigere Umbauten und Reparaturen geeignet ist.From the German utility model DE-U-85 07 324 a lower ceiling construction is also known, which consists of intersecting support rails with a substantially U-shaped profile that is open at the bottom and at the lower end of the open leg horizontally outward projections for the Bearing of the ceiling elements.
With this ceiling construction, it proves to be disadvantageous that a number of special adaptations have to be carried out during construction in order to achieve a closed ceiling surface which is flush with the mounting rails. Due to the U-profiles open at the bottom, it is e.g. B. necessary to insert special cover rails. The sealing strips for the ceiling elements must be glued to the side projections of the mounting rails. All of this means that the construction of the suspended ceiling construction is relatively complicated and is only suitable for one-time permanent installations, but not for more frequent conversions and repairs.

Der Erfindung liegt die Aufgabe zugrunde, eine Deckenverkleidung der eingangs genannten Art zu schaffen, welche bei unkompliziertem Aufbau eine optisch ansprechende Ausgestaltung und eine sichere Abdeckung'gewährleistet und bei der Umbauten und die Befestigung zusätzlicher Anbauten oder Einbauten problemlos möglich sind.The invention has for its object to provide a ceiling cladding of the type mentioned, which ensures a visually appealing design and a secure cover 'with uncomplicated construction and are easily possible in the conversions and the attachment of additional attachments or internals.

Die Aufgabe wird erfindungsgemäß gelöst, indem die Längsstreben und die Querstreben oder die seitlichen Vorsprünge der Längsstreben und der Querstreben des Trägerrasters jeweils von einstückigen, verwindungssteifen Profilen gebildet sind, wobei die Vorsprünge oder die Streben zur Aufnahme von Leitungen oder dgl. als allseitig geschlossene, kastenförmige Profilquerschnitte ausgebildet sind, indem weiterhin die seitlichen Vorsprünge an der Oberseite wenigstens einen sich längs des jeweiligen Vorsprungs nach oben erstreckenden Steg aufweisen und die Dichtungen zwischen dem Steg und der Seitenwand der Streben bzw. zwischen den Stegen aufgenommen sind und indem schließlich die Kassetten mittels sich an den Seitenwänden der Streben abstützenden Federelementen auf die Stege gedrückt werden und in ihrer Tiefe und Kontur derart ausgestaltet sind, daß ihre geschlossenen Bodenflächen mit den Streben flächenbündig angeordnet sind.The object is achieved in that the longitudinal struts and the cross struts or the lateral projections of the longitudinal struts and the cross struts of the support grid are each formed by one-piece, torsion-resistant profiles, the projections or struts for receiving lines or the like being closed on all sides, box-shaped Profile cross-sections are formed by the lateral projections on the top at least one web extending along the respective projection upwards have and the seals between the web and the side wall of the struts or between the webs are received and by finally the cassettes are pressed by means of spring elements supported on the side walls of the struts on the webs and are designed in depth and contour such that their closed floor surfaces are arranged flush with the struts.

Einbauten, beispielsweise Trennwände nur über einem bestimmten Zeitraum eingebaut werden sollen. Bei der nachfolgenden Demontage beeinflussen die möglicherweise in den Längsstreben verbleibenden Bohrungen nicht die Dichtigkeit der Deckenverkleidung. Da die Längsstreben über eine ausreichende Festigkeit verfügen, ist es erfindungsgemäß somit möglich, an diesen weitere Anbauten, auch größeren Gewichts zu befestigen, beispielsweise Leuchten im medizinischen Bereich, Aufhängungen für Laborgeräte oder ähnliches. In günstiger Weise können Vorsprünge als Leitungskanäle ausgebildet sein. Bei dieser Ausgestaltungform stehen somit zwei Leitungskanäle bei jeder Längsstrebe zur Verfügung, so daß sich die Applikationsmöglichkeiten für Anbaugeräte wesentlich erhöhen.Fixtures, for example partitions, should only be installed over a certain period of time. During the subsequent dismantling, the holes that may remain in the longitudinal struts do not affect the tightness of the ceiling cladding. Since the longitudinal struts have sufficient strength, it is thus possible according to the invention to attach further attachments, also of greater weight, to these, for example lamps in the medical field, suspensions for laboratory devices or the like. Protrusions can advantageously be designed as conduit channels. In this embodiment, two conduit channels are thus available for each longitudinal strut, so that the application options for attachments are significantly increased.

In einer besonders günstigen Ausgestaltungsform ist die Längsstrebe so ausgebildet, daß diese in ihrem mittleren Bereich den Leitungskanal und darüber angeordnet den rohrförmigen Querschnittsbereich aufweist. Diese Ausgestaltungsform kann eine schmälere Ausgestaltung der Längsstrebe ermöglichen und stellt zudem sicher, daß nicht in unbeabsichtigter Weise doch Durchbohrungen durch Teile der Längs-. strebe erfolgen, welche zu einer Undichtigkeit führen können.In a particularly favorable embodiment, the longitudinal strut is designed such that it has the conduit channel in its central region and, above it, the tubular cross-sectional region. This embodiment can enable a narrower configuration of the longitudinal strut and also ensures that through-drilling through parts of the longitudinal struts is not inadvertently. strive, which can lead to a leak.

Um eine einfache Aufhängungsmöglichkeit für die Längsstreben zu schaffen, kann in günstiger Weise vorgesehen sein, daß der rohrförmige Querschnittsbereich einen U-förmigen Querschnitt aufweist, in welchen Aufhängungselemente einhängbar sind. Bei dieser Ausgestaltungsform ist es nicht erforderlich, die Aufhängungselemente über zusätzliche Verbindungselemente, beispielsweise Schrauben zu befestigen, vielmehr können die Aufhängungselemente direkt in die Längsstreben eingehängt werden.In order to provide a simple suspension option for the longitudinal struts, it can advantageously be provided that the tubular cross-sectional area has a U-shaped cross section, in which suspension elements can be suspended. In this embodiment, it is not necessary to fasten the suspension elements via additional connecting elements, for example screws, but rather the suspension elements can be hung directly into the longitudinal struts.

In einer besonders günstigen Ausgestaltungsform ist die Längsstrebe im wesentlichen rechteckig ausgebildet und weist einen horizontalen Trennsteg zur Trennung des Leitungskanals von dem rohrförmigen Querschnittsbereich auf. Diese Ausgestaltungsform bringt hinsichtlich der Festigkeitseigenschaften der Länggstrebe wesentliche Vorteile. Weiterhin ist es möglich, die Ausgestaltung des Leitungskanals so vorzunehmen, daß eine Beschädigung des horizontalen Trennstegs während der Montage von Anbauten, beispielsweise durch Bohrwerkzeuge oder ähnliches in sicherer Weise ausgeschlossen ist.In a particularly favorable embodiment, the longitudinal strut is essentially rectangular and has a horizontal separating web for separating the conduit from the tubular cross-sectional area. This embodiment brings significant advantages in terms of the strength properties of the longitudinal strut. Furthermore, it is possible to design the conduit in such a way that damage to the horizontal separating web during the installation of attachments, for example by drilling tools or the like, is prevented in a safe manner.

Um eine besonders gute Anlage der Kassette an den Längsstreben und Querstreben zu ermöglichen, kann erfindungsgemäß weiterhin vorgesehen sein, daß die Kassette an ihrem äußeren, unteren Randbereich einen umlaufenden Stufenfalz aufweist und mit der horizontalen Fläche des Stufenfalz auf den Vorsprüngen so aufliegt, daß die Unterseite der Kassette, der Längsstreben und der Querstreben in einer Ebene angeordnet sind.In order to allow a particularly good contact of the cassette with the longitudinal struts and transverse struts, it can further be provided according to the invention that the cassette has a circumferential step fold on its outer, lower edge region and rests on the projections with the horizontal surface of the step fold so that the underside the cassette, the longitudinal struts and the cross struts are arranged in one plane.

Zur Fixierung der Kassetten und um diese mit einer ausreichenden Kraft gegen die Dichtungen zu drücken, kann erfindungsgemäß vorgesehen sein, daß an den Längsstreben oder an den Querstreben die Kassetten in ihrer Position fixierende Federelemente gehalten sind. Die Federelemente können in günstiger Weise als Blattfedern ausgebildet sein, wobei die Enden dieser Blattfedern in an den Seitenwänden der Längs- bzw. Querstreben ausgebildeten, sich gegenüberliegenden Nuten gehalten sind. In einer weiteren Entwicklung der Erfindung kann weiterhin vorgesehen sein, daß die Nuten von der jeweiligen Seitenwand und einer hierzu parallel verlaufenden, vom oberen Ende der Seitenwand nach unten verlaufenden Leiste einerseits und einer auf der Oberseite des Vorsprungs ausgebildeten, nach oben parallel zur Seitenwand verlaufenden Leiste andererseits gebildet sind.To fix the cassettes and to press them against the seals with sufficient force, it can be provided according to the invention that the cassettes are held in their position on the longitudinal struts or on the transverse struts. The spring elements can advantageously be designed as leaf springs, the ends of these leaf springs being held in opposing grooves formed on the side walls of the longitudinal or transverse struts. In a further development of the invention it can further be provided that the grooves of the respective side wall and a parallel to it, running from the upper end of the side wall down bar on the one hand and a formed on the top of the projection, upward parallel to Sidewall extending bar are formed on the other hand.

Um sicherzustellen, daß die Kassetten in einfacher Weise eingesetzt bzw. demontiert werden können, wenn die Federelemente zwischen den beiden Enden einen abgewinkelten Abschnitt aufweisen, dessen einer Schenkel im wesentlichen vertikal veläuft, sich an der Seitenfläche der Kassette federnd abstützt und etwa bis zur Höhe der oberen Kante der Kassette verläuft und dessen anderer Schenkel oberhalb der oberen Kante der Kassette verläuft und bezüglich der Seitenwand der Strebe schräg nach außen oben abgewinkelt ist. Weiterhin kann es günstig sein, wenn sich an den einen Schenkel ein sich vorzugsweise gradlinig zur unteren Nut hin erstreckender Schenkel und an den anderen Schenkel ein sich vorzugsweise gradlinig zur oberen Nut hin erstreckender Schenkel anschließt.To ensure that the cassettes can be inserted or removed in a simple manner if the spring elements have an angled section between the two ends, one leg of which runs essentially vertically, is resiliently supported on the side surface of the cassette and approximately up to the height of the the upper edge of the cassette and the other leg of which runs above the upper edge of the cassette and is angled obliquely outwards with respect to the side wall of the strut. Furthermore, it can be expedient if one leg adjoins a leg which preferably extends in a straight line towards the lower groove and on the other leg a leg which preferably extends in a straight line towards the upper groove.

Die erfindungsgemäße Deckenverkleidung besteht im wesentlichen aus horizontal angeordneten, zueinander parallen Längsstreben 2, aus Querstreben 4, die zwischen den Längsstreben 2 angeordnet sind und mit ihren Enden jeweils an den Längsstreben befestigt sind, sowie aus Kassetten 6, die in den von den Längsstreben 2 und den Querstreben 4 getragen sind. Wie aus Fig. 3 ersichtlich, sind die Längsstreben 2 über sich von der Oberseite 12 der Längsstreben 2 nach oben erstreckende Traglaschen 14 an Trägern 8 befestigt, die ihrerseits beispielsweise mittels Gewindestäben 16 relativ zur nicht dargestellten Raumdecke höhenverstellbar sind. Die Traglaschen 14 der Längsstreben 2 sind an ihrem oberen Ende abgewinkelt, so daß die Längsstreben über den sich horizontal erstreckenden Winkelschenkel 18 der Traglasche 14 an den Trägern 8 aufgehängt werden können. Zusätzlich werden die Traglaschen 14 mittels Schrauben 20 an den Trägern 8 gesichert.The ceiling cladding according to the invention consists essentially of horizontally arranged, parallel longitudinal struts 2, of cross struts 4, which are arranged between the longitudinal struts 2 and are each fastened with their ends to the longitudinal struts, and from cassettes 6, which in the of the longitudinal struts 2 and the cross struts 4 are worn. As can be seen from FIG. 3, the longitudinal struts 2 are above one another from the upper side 12 of the longitudinal struts 2 supporting straps 14 extending at the top are fastened to supports 8, which in turn are height-adjustable, for example by means of threaded rods 16, relative to the ceiling, not shown. The support straps 14 of the longitudinal struts 2 are angled at their upper end, so that the longitudinal struts can be suspended from the supports 8 via the horizontally extending angle leg 18 of the support strap 14. In addition, the support straps 14 are secured to the supports 8 by means of screws 20.

Die Längsstreben 2 und die Querstreben 4 sind als Aluminium-Profile ausgebildet. Die von den Längsstreben 2 und den Querstreben 4 getragenen Kassetten 6 sind aus elektrolytisch verzinktem Stahlblech hergestellt, wobei die Sichtseiten sowohl der Kassetten 6 als auch der Längsstreben 2 und der Querstreben 4 mit thermogehärtetem Lack beispielsweise im Farbton RAL 9010 beschichtet sind.The longitudinal struts 2 and the cross struts 4 are designed as aluminum profiles. The cassettes 6 carried by the longitudinal struts 2 and the cross struts 4 are made of electrolytically galvanized sheet steel, the visible sides of both the cassettes 6 and the longitudinal struts 2 and the cross struts 4 being coated with thermally hardened paint, for example in the color RAL 9010.

Die Form der Längsstreben 2 ist insbesondere aus Fig. 3 ersichtlich. Die Längsstreben 2 sind im wesentlichen als rechteckförmiges Kastenprofil ausgebildet, wobei die Oberseite 12 des Kastenprofils zum größten Teil geöffnet ist, damit das Innere des Kastenprofils zugänglich ist. An den beiden Längsseiten 22, 24 des Kastenprofils sind in Längsrichtung der Längsstreben verlaufende, durchgehende, seitlich vorspringende Auflager 26 angeformt. Diese Auflager 26 sind ebenfalls kastenprofilartig ausgebildet, wobei die Unterseite 28 der Auflager 26 in einer Ebene mit der Unterseite 30 der kastenprofilartigen Längsstrebe 2 liegt.The shape of the longitudinal struts 2 can be seen in particular from FIG. 3. The longitudinal struts 2 are designed essentially as a rectangular box section, the upper side 12 of the box section being largely open so that the inside of the box section is accessible. Continuous, laterally projecting supports 26 are formed on the two longitudinal sides 22, 24 of the box section in the longitudinal direction of the longitudinal struts. These supports 26 are also designed in the manner of a box profile, the underside 28 of the supports 26 being in one plane with the underside 30 of the longitudinal strut 2 in the manner of a box profile.

An der nach oben weisenden Oberseite 32 eines jeden Auflagers 26 sind jeweils drei sich in Längsrichtung der Längsstrebe 2 erstreckende, vertikale Stege 34, 36, 38 ausgebildet, wobei der äußere Steg 34 eine Verlängerung der Seitenwand 40 des kastenprofilförmigen Auflagers 26 dar stellt, der Steg 38 nahe der Längsseite 22 der Längsstrebe 2 angeordnet ist und mit dieser eine Nut 42 definiert und der Steg 36 zwischen dem Steg 34 und dem Steg 38 angeordnet ist.On the upward-facing upper side 32 of each support 26, three vertical webs 34, 36, 38 are formed, each extending in the longitudinal direction of the longitudinal strut 2, the outer web 34 being an extension of the side wall 40 of the box-shaped support 26 the web 38 is arranged near the longitudinal side 22 of the longitudinal strut 2 and defines a groove 42 therewith and the web 36 is arranged between the web 34 and the web 38.

Zwischen den Steg 34 und den Steg 36 ist ein Dichtungsstreifen 44 eingelegt, der beispielsweise aus Gummi bestehen kann, sich über die gesamte Länge der Längsstrebe erstreckt und im nicht komprimierten Zustand geringfügig über die Oberkanten der Stege 34, 36 hinausragt.Between the web 34 and the web 36, a sealing strip 44 is inserted, which can be made of rubber, for example, extends over the entire length of the longitudinal strut and, in the non-compressed state, projects slightly beyond the upper edges of the webs 34, 36.

Am oberen Bereich der beiden Längsseiten 22, 24 ist jeweils ein parallel zu den Längsseiten und über die gesamte Länge der Längsseiten verlaufender, nach unten gerichteter Steg 46 angeformt, der zwischen sich und der benachbarten Seitenwand 22 bzw. 24 jeweils eine Nut 48 definiert. Die sich gegenüberliegenden Nuten 42, 48 dienen zur Aufnahme von weiter unten noch näher zu beschreibenden Federn 50.On the upper area of the two long sides 22, 24, a web 46 is formed, which runs parallel to the long sides and over the entire length of the long sides and defines a groove 48 between them and the adjacent side wall 22 or 24. The opposing grooves 42, 48 serve to receive springs 50 to be described in more detail below.

In den Längsseiten 22, 24 der Längsstreben 2 sind, wie aus Fig. 5 ersichtlich, etwa in halber Höhe unter einem jeweils vorgegebenen Rasterabstand von beispielsweise 60 cm Durchgangsbohrungen 52 zur Aufnahme von Schrauben 54 vorgesehen, welche zur kraftschlüssigen Befestigung der Querstreben 4 an den Längsstreben 2 dienen. Die Gesamtbreite der Längsstreben 2 einschließlich deren Auflager 26 kann etwa 10 cm betragen, bei einer Höhe von etwa 7,2 cm.In the longitudinal sides 22, 24 of the longitudinal struts 2, as can be seen from FIG. 5, approximately half a height under a predetermined grid spacing of, for example, 60 cm, through holes 52 are provided for receiving screws 54, which are used for the non-positive fastening of the cross struts 4 to the longitudinal struts 2 serve. The total width of the longitudinal struts 2, including their supports 26, can be approximately 10 cm, with a height of approximately 7.2 cm.

Zur Queraussteifung der Längsstreben sind im Abstand von beispielsweise 100 cm verzinkte Rostwinkel mit zusätzlichen Diagonalstreben als Schubtraversen vorgesehen.For the transverse stiffening of the longitudinal struts, galvanized grate angles with additional diagonal struts are provided as thrust beams at a distance of, for example, 100 cm.

Der Aufbau der Querstreben 4 ist insbesondere aus Fig. 2 ersichtlich. Die Querstreben 4 sind ebenfalls als Aluminiumprofil ausgebildet und umfassen eine hochkant stehende Leiste 80, längs deren unterem Ende beidseitig in Längsrichtung der Leiste 80 verlaufende Auflager 56 ausgebildet sind, die sich zu beiden Seiten der Leite 80 erstrecken und deren Unterseiten 58 die Unterseite der Querstreben bilden. Die Auflager 56 weisen den gleichen Querschnitt wie die Auflager 26 der Längsstreben 2 auf und sind demnach kastenprofilartig ausgebildet mit Seitenwänden 70 und Oberseiten 62, von denen sich in Längsrichtung verlaufende Stege 64, 66, 68 nach oben erstrecken, wobei zwischen den Stegen 64, 66 Dichtungsstreifen 74 angeordnet sind und wobei zwischen den Stegen 68 und der benachbarten Seitenfläche der Leiste 80 Nuten 72 ausgebildet sind.The structure of the cross struts 4 can be seen in particular from FIG. 2. The cross struts 4 are also designed as an aluminum profile and comprise an upright ledge 80, along the lower end of which on both sides in the longitudinal direction of the bar 80 extending supports 56 are formed, which extend to both sides of the line 80 and whose undersides 58 form the underside of the cross struts. The supports 56 have the same cross-section as the supports 26 of the longitudinal struts 2 and are therefore designed in the manner of a box profile with side walls 70 and top sides 62, from which webs 64, 66, 68 extending in the longitudinal direction extend upwards, between the webs 64, 66 Sealing strips 74 are arranged and 80 grooves 72 are formed between the webs 68 and the adjacent side surface of the strip.

Längs des oberen Endes der Leiste 80 sind ähnlich wie im Falle der Längsstreben 2 in Längsrichtung verlaufende, nach unten weisende Stege 76 ausgebildet, die zwischen sich und den benachbarten Seitenflächen der Leiste 80 Nuten 78 definieren. Die sich gegenüberliegenden Nuten 72, 78 dienen, wie im Falle der Längsstreben 2, zur Aufnahme der Enden von Federn 50. Längs der oberen Kante der Querstreben 4 ist eine rechtwinklig zur Ebene der Leiste 80 verlaufende Versteifungsleiste 60 ausgebildet.Along the upper end of the strip 80, in the same way as in the case of the longitudinal struts 2, longitudinally extending, downwardly pointing webs 76 are formed which define grooves 78 between themselves and the adjacent side faces of the strip 80. The opposing grooves 72, 78 serve, as in the case of the longitudinal struts 2, for receiving the ends of springs 50. A stiffening bar 60 running at right angles to the level of the bar 80 is formed along the upper edge of the cross bars 4.

Die Leiste 80 weist in etwa mittig eine in deren Längsrichtung verlaufende Verdickung 82 auf, in der mittig eine in Längsrichtung der Querstrebe 4 verlaufende Gewindebohrung 84 ausgebildet ist. Wie aus Fig. 3 ersichtlich, sind die Querstreben 4 in ihren unteren Endkanten mit einer stufenförmigen, rechtwinkligen Ausnehmung 86 versehen, die so dimensioniert ist, daß die Querstreben 4 beim Ansetzen an die Längsstreben 2 mit der oberen, horizontalen Fläche der Ausnehmung 86 auf den Auflagern 26 aufliegen und mit ihrer Stirnfläche 87 gleichzeitig an den Außenseiten der Stege 46 der Längsstreben 2 anliegen. Die Breite der Querstreben 4 kann im Falle des hier beschriebenen Ausführungsbeispiels etwa 4 cm betragen und die Höhe der Querstreben 4 entspricht der Höhe der Längsstreben 2 und beträgt somit 7,2 cm.The strip 80 has a thickening 82 extending approximately in the center in the longitudinal direction, in which a threaded bore 84 extending in the longitudinal direction of the cross strut 4 is formed in the center. 3, the cross struts 4 are provided in their lower end edges with a step-shaped, rectangular recess 86 which is dimensioned so that the cross struts 4 when attached to the longitudinal struts 2 with the upper, horizontal surface of the recess 86 on the Support 26 and at the same time rest with their end face 87 on the outer sides of the webs 46 of the longitudinal struts 2. In the case of the exemplary embodiment described here, the width of the cross struts 4 can be approximately 4 cm and the height of the cross struts 4 corresponds the height of the longitudinal struts 2 and is thus 7.2 cm.

Zum Befestigen der Querstreben 4 an den Längsstreben 2 werden die Schrauben 54 vom Inneren der Längsstreben 2 durch die Durchgangsbohrungen 52 der Längsseiten 22, 24 der Längsstreben 2 hindurchgeführt und in die den Durchgangsbohrungen 52 gegenüberliegenden Gewindebohrungen 84 der Querstreben 4 eingedreht.To fasten the cross struts 4 to the longitudinal struts 2, the screws 54 are guided from the inside of the longitudinal struts 2 through the through bores 52 of the longitudinal sides 22, 24 of the longitudinal struts 2 and screwed into the threaded bores 84 of the cross struts 4 opposite the through bores 52.

Die Abmessungen der Kassetten 6 sind etwas kleiner als die durch die Längsseiten 22, 24 der Längsstreben und die Außenseiten der Leiste 80 der Querstreben definierten Rastermaße, jedoch größer als die durch die Seitenwände 40, 70 der Auflager 26, 56 definierten Rastermaße. Längs ihrer Außenseiten sind die Kassetten 6 unten mit einem umlaufenden Stufenfalz 88 versehen. Wenn die Kassetten 6 in die durch die Längsstreben 2 und die Querstreben 4 definierten Rasterfelder 10 eingelegt sind, so liegen sie mit den horizontalen Flächen 90 des Stufenfalzes 88 auf den von den Auflagern 26, 56 getragenen Dichtungsstreifen 44, 74 dichtend auf. Die Höhe des Stufenfalzes 88 ist hierbei so ausgebildet, daß die Unterseiten 92 mit den Unterseiten der Längsstreben 2 und der Querstreben 4 bündig sind.The dimensions of the cassettes 6 are somewhat smaller than the grid dimensions defined by the long sides 22, 24 of the longitudinal struts and the outer sides of the strip 80 of the cross struts, but larger than the grid dimensions defined by the side walls 40, 70 of the supports 26, 56. Along their outer sides, the cassettes 6 are provided with a circumferential step fold 88 at the bottom. When the cassettes 6 are inserted into the grid fields 10 defined by the longitudinal struts 2 and the cross struts 4, they lie with the horizontal surfaces 90 of the step fold 88 in a sealing manner on the sealing strips 44, 74 carried by the supports 26, 56. The height of the step fold 88 is designed so that the undersides 92 are flush with the undersides of the longitudinal struts 2 and the cross struts 4.

Zur Fixierung der Position der Kassetten 6 sind die an den Längsstreben 2 und den Querstreben 4 getragenen Federn 50 vorgesehen. Die Federn 50 weisen an ihren beiden Enden jeweils einen parallel zu den Längsseiten 22, 24 bzw. der Leiste 80 verlaufenden Schenkel auf, wobei der untere Schenkel der Feder 50 in der Nut 42 bzw. 72 und der obere Schenkel der Feder 50 in der oberen Nut 48 bzw. 78 geführt ist. In ihrem mittleren Bereich ist an den Federn 50 ein vertikaler Schenkel 94 ausgebildet, der an der Seitenwand der Kassette 6 im Bereich deren oberen Kante anliegt, sich nach oben bis zum Bereich der oberen Kante 96 der Kassette er streckt und unter Vorspannung an der Kassette anliegt. An diesen vertikalen Schenkel der Feder 50 schließt sich ein kurzer, schräg nach oben außen verlaufender Schenkel 98 an. Vom äußeren Ende dieses Schenkels 98 führt ein geradlinig verlaufender Schenkel 100 zum oberen, in der Nut 48 bzw. 78 geführten Endbereich der Feder 50. Vom unteren Ende des vertikalen Schenkels 94 führt ein geradlinig verlaufender, weiterer Schenkel 102 der Feder 50 zum unteren, in der Nut 42 bzw. 72 geführten Endabschnitt der Feder 50.The springs 50 carried on the longitudinal struts 2 and the cross struts 4 are provided to fix the position of the cassettes 6. The springs 50 each have a leg running parallel to the longitudinal sides 22, 24 or the strip 80 at their two ends, the lower leg of the spring 50 in the groove 42 or 72 and the upper leg of the spring 50 in the upper Groove 48 and 78 is guided. In its central region, a vertical leg 94 is formed on the springs 50, which bears against the side wall of the cassette 6 in the region of its upper edge, and extends up to the region of the upper edge 96 of the cassette stretches and is under tension against the cassette. This vertical leg of the spring 50 is adjoined by a short leg 98, which extends obliquely upward on the outside. From the outer end of this leg 98, a straight leg 100 leads to the upper end region of the tongue 50, which is guided in the groove 48 or 78. From the lower end of the vertical leg 94, a straight leg 102 of the tongue 50 leads to the lower, in of the groove 42 and 72 guided end portion of the spring 50th

Für jede Kassette 6 sind im Falle des hier beschriebenen Ausführungsbeispiels sechs Federn 50 an den Längsstreben 2 und den Querstreben 4 verteilt angeordnet. Die Federn 50 können in einfacher Weise durch Zusammendrücken der Schenkel 100, 102 an der gewünschten Stelle in die Führungsnuten eingesetzt werden. Auch können die Federn 50 bei Bedarf innerhalb der Führungsnuten verschoben werden. Beim Einsetzen der Kassetten 6 in die Rasterfelder 10 laufen die Unterkanten der Kassetten 6 auf den Schenkeln 100 der Federn 50 auf und drücken diese zur Seite. Sobald die Kassetten 6 ihre in den Figuren dargestellte Sollposition erreicht haben, schnappen die Federn mit ihren Schenkeln 98, 100 über der oberen Kante der Kassetten 6 nach außen bei gleichzeitiger Anlage der vertikalen Schenkel 94 an den Seitenflächen der Kassette 6. Auf diese Weise werden die Kassetten 6 sicher in ihrer Sollposition gehalten.In the case of the exemplary embodiment described here, six springs 50 are distributed on the longitudinal struts 2 and the transverse struts 4 for each cassette 6. The springs 50 can be inserted into the guide grooves in a simple manner by compressing the legs 100, 102 at the desired location. The springs 50 can also be moved within the guide grooves if necessary. When the cassettes 6 are inserted into the grid fields 10, the lower edges of the cassettes 6 run onto the legs 100 of the springs 50 and push them to the side. As soon as the cassettes 6 have reached their desired position shown in the figures, the springs snap with their legs 98, 100 to the outside over the upper edge of the cassettes 6 while at the same time the vertical legs 94 rest against the side surfaces of the cassette 6. In this way, the Cassettes 6 held securely in their target position.

In Fig. 6 ist eine Schnittansicht, ähnlich Fig. 3, durch eine Längsstrebe des erfindungsgemäßen Trägerrasters dargestellt, welche im wesentlichen im Aufbau der in Fig. 3 gezeigten Längsstrebe entspricht. Gleiche Teile wurden mit gleichen Bezugsziffern versehen. Die in Fig. 6 gezeigte Längsstrebe weist an den Vorsprüngen 26 jeweils sich nach oben erstreckende Stege 34 auf, auf welchen, wie dargestellt, die Kassetten 6 mit einer horizontalen Fläche des Stufenfalzes 88 aufliegen. Es ist somit sichergestellt, daß die Kassetten sich stets in Anlage mit den Stegen 34 befinden, so daß eine exakte Zuordnung und Fluchten der Anordnung der Unterseiten 30 der Längsstreben und der Unterseiten der Kassetten 6 gewährleistet ist. In dem zwischen der Längsseite 24 der Längsstrebe und dem Steg 34 ausgebildeten Zwischenraum ist eine Dichtung 44 angeordnet, welche eine ebene untere Auflagefläche 104 aufweist, die mit einem horizontalen Bereich des Vorsprungs 26 verbindbar ist. Beispielsweise mittels einer Klebverbindung. Die Dichtung 34 ist im wesentlichen schlauchförmig ausgebildet und weist im unbelasteten Zustand eine Höhe auf, welche größer ist, als die entsprechende Höhe des Steges 34. Auf diese Weise wird sichergestellt, daß beim Auflegen der Kassetten 6 die Dichtung 44 stets in vorgegebenem Maße zusammengedrückt wird.FIG. 6 shows a sectional view, similar to FIG. 3, through a longitudinal strut of the support grid according to the invention, which essentially corresponds in structure to the longitudinal strut shown in FIG. 3. The same parts have been given the same reference numbers. The longitudinal strut shown in Fig. 6 has on the projections 26 each upwardly extending webs 34 on which, as shown, the cassettes 6 with a horizontal surface of the Step fold 88 rest. It is thus ensured that the cassettes are always in contact with the webs 34, so that an exact assignment and alignment of the arrangement of the undersides 30 of the longitudinal struts and the undersides of the cassettes 6 is ensured. In the space formed between the longitudinal side 24 of the longitudinal strut and the web 34, a seal 44 is arranged which has a flat lower contact surface 104 which can be connected to a horizontal region of the projection 26. For example by means of an adhesive connection. The seal 34 is essentially tubular and has a height in the unloaded state which is greater than the corresponding height of the web 34. In this way it is ensured that the seal 44 is always compressed to a predetermined extent when the cassettes 6 are placed on top .

Die in Fig. 6 gezeigte Längsstrebe ist in Form eines Hohlprofiles ausgebildet und weist einen im wesentlichen rechteckigen, geschlossenen Leitungskanal 124 auf, welcher von der Unterseite 30, den Längsseiten 24 und einem horizontal verlaufenden Trennsteg 126 gebildet wird. Der Leitungskanal 124 ist somit in sich geschlossen und gegenüber einem über ihm angeordneten rohrförmigen Querschnittsbereich 128 abgedichtet. Der rohrförmige Querschnittsbereich weist im wesentlichen eine U-förmig Ausgestaltung auf, so daß in diesem die Traglasche 14 einführbar ist, so wie dies in Fig. 6 gezeigt ist.The longitudinal strut shown in FIG. 6 is designed in the form of a hollow profile and has an essentially rectangular, closed conduit channel 124, which is formed by the underside 30, the longitudinal sides 24 and a horizontally running separating web 126. The conduit 124 is thus self-contained and sealed against a tubular cross-sectional area 128 arranged above it. The tubular cross-sectional area essentially has a U-shaped configuration, so that the mounting bracket 14 can be inserted therein, as shown in FIG. 6.

Der Leitungskanal 124 kann zur Durchführung elektrischer Kabel oder von Rohren, beispielsweise für eine Sprinkleranlage verwendet werden. Durch seine Abdichtung mittels des Trennsteges 126 ist es weiterhin möglich, an der Unterseite 30 der Längsstrebe 2 Anbauten anzubringen, beispielsweise Trennwände, zusätzliche Leuchten oder ähnliches, ohne daß dadurch die Dichtigkeit der Deckenverkleidung beeinträchtigt würde.The conduit 124 can be used to pass electrical cables or pipes, for example for a sprinkler system. Due to its sealing by means of the separating web 126, it is also possible to add attachments to the underside 30 of the longitudinal strut 2, for example dividing walls, additional lights or the like, without this affecting the tightness of the ceiling cladding would.

Die Traglasche 14 ist bei dem in Fig. 6 gezeigten Ausführungsbeispiel mit einem Aufhänger 130 verbunden, wobei die Verbindung mittels nur schematisch angedeuteter Bolzen oder Schrauben 132 erfolgen kann.In the exemplary embodiment shown in FIG. 6, the carrying strap 14 is connected to a hanger 130, it being possible for the connection to be made by means of bolts or screws 132 which are only indicated schematically.

An der Längsstrebe sind, ebenso wie in dem in Fig. 3 gezeigten Ausführungsbeispiel obere und untere Nuten 48, 42 ausgebildet, welche zur Halterung einer Feder 50 oder eines Federelementes dienen. Auf der rechten Bildhälfte von Fig. 6 ist ein Ausführungsbeispiel eines derartigen Federelementes 50 dargestellt.On the longitudinal strut, as in the exemplary embodiment shown in FIG. 3, upper and lower grooves 48, 42 are formed, which are used to hold a spring 50 or a spring element. An embodiment of such a spring element 50 is shown on the right half of FIG. 6.

Um eine sichere Befestigung an der Traglasche 14 sicherzustellen, weist diese einen unteren Querbereich auf, von dessen äußeren oberen Kantenaussicht Haltelaschen 136 nach oben erstrecken, welche in U-förmigen Nuten einbringbar sind, die von Rändern 138 der Oberseiten 12 gebildet werden. Somit ist auch bei Auftreten von Schwingungen ein Lösen der Traglasche 14 sicher verhindert.In order to ensure secure attachment to the support bracket 14, the latter has a lower transverse region, from the outer upper edge view of which retaining tabs 136 extend upwards, which can be introduced in U-shaped grooves which are formed by edges 138 of the top sides 12. Thus, loosening of the support bracket 14 is reliably prevented even when vibrations occur.

Eine Verbindung zwischen der Längsstrebe 2 und einer Querstrebe 4 kann mittels eines Winkels 140 erfolgen, welcher in einer Längsnut 142 der Längsseite 24 der Längsstrebe 2 ausgebildet ist. Der Winkel 140 kann beispielsweise mit der Längsstrebe 2 verschraubt werden.A connection between the longitudinal strut 2 and a cross strut 4 can take place by means of an angle 140, which is formed in a longitudinal groove 142 of the longitudinal side 24 of the longitudinal strut 2. The angle 140 can be screwed to the longitudinal strut 2, for example.

In Fig. 7 ist ein Ausführungsbeispiel, ähnlich Fig. 2, einer erfindungsgemäßen Querstrebe dargestellt, welche hinsichtlich ihres seitlichen Aufbaus der in Fig. 6 gezeigten Längsstrebe entspricht. Auch bei dieser Querstrebe sind die Stege 64 so ausgebildet, daß die Kassetten mit ihrem Stufenfalz 88 direkt auf den Stegen 64, nicht jedoch auf den Dichtungen 44 aufliegen. Die Dichtung 44 ist in gleicher Weise ausgebildet, wie bei dem in Fig. 6 gezeigten Ausführungsbeispiel. Ebenso sind die oberen und unteren Nuten 78, 72 zur Aufnahme der Federelemente 50 in gleicher Weise ausgebildet.FIG. 7 shows an embodiment, similar to FIG. 2, of a cross strut according to the invention, which corresponds in terms of its lateral structure to the longitudinal strut shown in FIG. 6. Also in this cross strut, the webs 64 are designed such that the cassettes with their step fold 88 rest directly on the webs 64, but not on the seals 44. The seal 44 is the same Formed as in the embodiment shown in Fig. 6. Likewise, the upper and lower grooves 78, 72 for receiving the spring elements 50 are formed in the same way.

Die in Fig. 7 gezeigte Querstrebe ist mittels einer Traglasche 14′ aufhängbar, welche an ihrem unteren Ende ein Halteelement 144 aufweist, welches einen im wesentlichen U-förmigen Querschnitt aufweist, mittels dessen ein Umgreifen des oberen Bereiches der Querstrebe möglich ist. Die freien Enden des Halteelementes 144 sind, wie in Fig. 7 gezeigt, nach innen umgebogen, um die Stege 76 zu hintergreifen. Da sich sowohl die Feder 50 als auch die Traglaschen 14′ jeweils nur über eine beschränkte Länge der Querstrebe erstrecken, tritt zwischen diesen keine unerwünschte Wechselwirkung ein.The cross strut shown in Fig. 7 can be suspended by means of a support bracket 14 ', which has at its lower end a holding element 144 which has a substantially U-shaped cross section, by means of which a gripping of the upper region of the cross strut is possible. As shown in FIG. 7, the free ends of the holding element 144 are bent inwards in order to engage behind the webs 76. Since both the spring 50 and the support straps 14 'each extend only over a limited length of the cross strut, no undesirable interaction occurs between them.

In den Fig. 8 und 9 sind Ausführungsbeispiele einer erfindungsgemäßen Wandabschlußstrebe dargestellt, mittels derer ein Wandanschluß einer Kassette 6 passend zu den örtlichen Gegebenheiten ausgebildet sein kann. Die Kassette 6 ist mit einem horizontalen Bereich 116 versehen, welcher beispielsweise in Form eines Teils der Unterseite der Kassette 6 ausgebildet sein kann.8 and 9 show exemplary embodiments of a wall end strut according to the invention, by means of which a wall connection of a cassette 6 can be designed to suit the local conditions. The cassette 6 is provided with a horizontal region 116, which can be designed, for example, in the form of part of the underside of the cassette 6.

Die Wandanschlußstrebe 106 weist einen ersten horizontalen Vorsprung 110 auf, auf welchen der horizontale Breich 116 der Kassette 6 auflegbar ist. Durch diese Ausgestaltung wird eine sichere Lagerung der Kassette 6 gewährleistet. Im wesentlichen parallel zu dem ersten Vorsprung 110 ist ein zweiter Vorsprung 114 einstückig mit der Wandanschlußstrebe 106 ausgebildet, dessen freien Ende eine Dichtung 112 angeordnet ist, welche den zweiten Vorsprung 114 umgreift und an ihrer Unterseite zumindest eine Dichtungslippe 118 aufweist, welche gegen den ersten Vorsprung 110 vorgespannt ist. Beim Einführen des horizontalen Bereichs 116 erfolgt somit in zuverlässiger Weise eine Abdichtung.The wall connection strut 106 has a first horizontal projection 110, on which the horizontal region 116 of the cassette 6 can be placed. This configuration ensures secure storage of the cassette 6. Essentially parallel to the first projection 110, a second projection 114 is formed in one piece with the wall connection strut 106, the free end of which is arranged a seal 112 which surrounds the second projection 114 and has at least one sealing lip 118 on its underside, which seals against the first projection 110 biased is. When the horizontal region 116 is inserted, a seal is thus made in a reliable manner.

Die Wandanschlußstrebe 106 kann, wie in Fig. 9 gezeigt, in Form eines Winkelprofiles ausgebildet sein, welches mit einer Wand 108 verschraubbar ist. Es ist jedoch auch möglich, die Wandanschlußstrebe 106, wie in Fig. 8 gezeigt, in Form eines Doppelwinkelprofiles auszugestalten, um auf diese Weise eine Schattennut 146 auszubilden.As shown in FIG. 9, the wall connection strut 106 can be designed in the form of an angle profile which can be screwed to a wall 108. However, it is also possible to design the wall connection strut 106 in the form of a double-angle profile, as shown in FIG. 8, in order to form a shadow groove 146 in this way.
