Description

Die Erfindung betrifft eine Vorrichtung zur abgehängten Befestigung einer Zwischendecke an einer Firste eines Tunnels, umfassend eine Kopfplatte, die mit Befestigungsmitteln an der Firste befestigbar ist, eine Stange und eine Ankerplatte für die Befestigung der Zwischendecke, wobei die Kopfplatte und die Ankerplatte über die Stange in Verbindung stehen.The invention relates to a device for suspended attachment of an intermediate ceiling to a roof of a tunnel, comprising a head plate fastened to the ridge by means of fasteners, a rod and an anchor plate for fixing the false ceiling, the head plate and the anchor plate passing over the rod Connection stand.

Im Tunnelbau wird in neuerer Bauweise unterhalb einer Firste eine Zwischendecke eingezogen. Im Hohlraum zwischen der Zwischendecke und der Firste können die erforderlichen Einrichtungen für eine Belüftung, aber auch andere erforderliche Einrichtungen sichtfrei verbaut werden.In tunnel construction, a false ceiling is lowered below a ridge. In the cavity between the false ceiling and the roof, the necessary facilities for ventilation, but also other required facilities can be installed without visible sight.

Um statischen Erfordernissen zu genügen, kann die Zwischendecke bei reiner Randlagerung bzw. ohne Zwischenabhängung mit einer vergleichsweise großen Stärke ausgeführt werden, was allerdings einen hohen Materialaufwand erfordert und daher auch entsprechende Kosten nach sich zieht. Wesentlich kostensparender ist es, die Zwischendecke durch geeignete Verbindungsmittel an der Firste abgehängt zu befestigen. Dadurch kann die Zwischendecke wesentlich dünner und damit materialsparender gestaltet werden. Sind die Verbindungsmittel zudem flexibel, können auch dynamische Belastungen relativ gut aufgenommen werden.In order to meet static requirements, the false ceiling can be performed with pure edge storage or without Zwischenhängung with a comparatively large strength, but this requires a high cost of materials and therefore also entails corresponding costs. It is much more cost-effective to fasten the false ceiling suspended from the roof by means of suitable connecting means. As a result, the false ceiling can be much thinner and thus made more material-saving. If the connection means are also flexible, dynamic loads can also be absorbed relatively well.

Aus dem Stand der Technik bekannte Vorrichtungen zur abgehängten Befestigung einer Zwischendecke umfassen eine Kopfplatte, die mit Befestigungsmitteln in einer Firste fixiert werden kann. An die Kopfplatte schließt ein Zwischenkörper mit einem Gelenk an, der eine (Anker-)Stange aufnimmt. Die (Anker-)Stange wiederum trägt an einem der Kopfplatte gegenüberliegenden Ende eine Ankerplatte, welche in die Zwischendecke einbetoniert wird. Aufgrund des im Zwischenkörper vorgesehenen Gelenks sind entsprechende Vorrichtungen flexibel. Wie im Rahmen der Erfindung erkannt wurde, stellt allerdings eine Verbindung des Zwischenkörpers mit der Kopfplatte ein Problem dar. Der Zwischenkörper ist an der Kopfplatte angeschweißt. Insbesondere bei gegebenen dynamischen Belastungen sind daher sehr hohe Anforderungen an die Schweißnähte zu stellen. Diese betrifft einerseits die Herstellung und die anschließende Prüfung der Vorrichtung auf Einsatztauglichkeit. Andererseits können dennoch bereits Kerben bekannterweise bei Schweißnähten dazu führen, dass diese einer Belastung nicht mehr standhalten.Prior art suspended ceiling fixture devices include a top plate that can be fixed in a ridge with fasteners. To the top plate connects an intermediate body with a joint which receives an (anchor) rod. The (anchor) rod in turn carries on an opposite end of the head plate an anchor plate, which is embedded in the false ceiling. Due to the provided in the intermediate body joint corresponding devices are flexible. As has been recognized within the scope of the invention, however, a connection of the intermediate body with the top plate is a problem. The intermediate body is welded to the top plate. Especially with given dynamic loads therefore very high demands are placed on the welds. On the one hand, this relates to the manufacture and the subsequent testing of the device for suitability for use. On the other hand, however, can already scores As is known, in welding seams, they can no longer withstand a load.

Bekannt sind auch Vorrichtungen, die kopfseitig in eine Firste einbetoniert werden, was aber einen hohen konstruktiven Aufwand mit sich bringt. Darüber hinaus können solche Vorrichtungen nicht für Sanierungen eingesetzt werden, da in diesem Fall die Firste bereits vorhanden ist.Also known are devices that are concreted into a ridge on the head, but this involves a high design effort. In addition, such devices can not be used for renovations, since in this case the ridge already exists.

Davon ausgehend ist es Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art anzugeben, mit welcher diese Nachteile vermieden werden können.On this basis, it is an object of the invention to provide a device of the type mentioned, with which these disadvantages can be avoided.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art gelöst, wenn die Stange an der Kopfplatte schweißnahtfrei gelagert ist.This object is achieved in a device of the type mentioned, when the rod is mounted free of welding seams on the top plate.

Erfindungsgemäß wird die Stange schweißnahtfrei mit der Kopfplatte mittelbar oder unmittelbar verbunden. Durch die vorgesehene lösbare Befestigung der Stange an der Kopfplatte ergibt sich zum einen eine einfache Herstellung. Zum anderen kann auch eine aufwendige Funktionsprüfung entfallen. Schließlich kann eine erfindungsgemäße Vorrichtung auch den gegebenen Belastungen im Einsatz standhalten.According to the invention, the rod is connected without welding seams directly or indirectly to the top plate. The intended releasable attachment of the rod to the top plate results in a simple production. On the other hand, a complex function test can be omitted. Finally, a device according to the invention can withstand the given loads during use.

Eine erfindungsgemäße Vorrichtung bietet zudem den Vorteil, dass diese bei der Sanierung von Tunneln eingesetzt werden kann. Der einfache Aufbau der Vorrichtung erlaubt es insbesondere, die Kopfplatte an einer vorhandenen Firste zu befestigen. Danach kann die Verbindung mit einer Zwischendecke erfolgen. Auch bei Neubauten wird zunächst die Firste erstellt, bevor die Kopfplatte an dieser befestigt wird. Dies erlaubt eine wesentlich einfachere Ausbildung der Vorrichtung als dies beispielsweise aus der EP 0 465 413 A1 oder der EP 0 541 487 A1 bekannt ist. Insbesondere kann die erfindungsgemäße Vorrichtung komplett schweißnahtfrei ausgebildet sein.A device according to the invention also has the advantage that it can be used in the rehabilitation of tunnels. The simple construction of the device allows in particular to attach the top plate to an existing ridge. Thereafter, the connection can be made with a false ceiling. Even with new buildings, the ridge is first created before the top plate is attached to this. This allows a much simpler design of the device than this, for example, from EP 0 465 413 A1 or the EP 0 541 487 A1 is known. In particular, the device according to the invention can be designed completely free of welding seams.

Die Stange kann mit der Kopfplatte insbesondere durch eine Schraubverbindung verbunden sein. Hierfür ist es zweckmäßig, dass die Stange an einem ersten Ende, das der Kopfplatte zugewendet ist, ein Außengewinde aufweist. In einer besonders einfachen Variante weist die Kopfplatte eine Bohrung mit einem Innengewinde auf, in welches ein Außengewinde der Stange eingreift. Hierfür weist die Stange zweckmäßigerweise an einem freien ersten Ende ein entsprechendes Außengewinde auf, das mit dem Innengewinde der Kopfplatte zusammenwirkt.The rod may be connected to the top plate in particular by a screw connection. For this purpose, it is expedient that the rod has a male thread at a first end facing the top plate. In a particularly simple variant, the top plate has a bore with an internal thread into which an external thread of the rod engages. For this purpose, the rod expediently a free first end to a corresponding external thread which cooperates with the internal thread of the top plate.

Besonders bevorzugt ist es, dass die Kopfplatte mit einer Bohrung und einer daran anschließenden Kugelpfanne ausgebildet ist. In diesem Fall ist es insbesondere möglich, dass eine Mutter mit einem verbreiterten Kugelkopf und einem Innengewinde vorgesehen ist, in welches ein Außengewinde der Stange einschraubbar ist, wobei der Kugelkopf in der Kugelpfanne der Kopfplatte gelagert ist. Durch diese konstruktiven Maßnahmen ergibt sich eine Vorrichtung, die auf einfache Weise herstellbar ist, zugleich aber bei geeigneter Auslegung auch ähnlich einem Gelenk eine Flexibilität und damit einen zwängungsfreien Ausgleich situationsbedingter Abweichungen von einer Lotlage sowie die Aufnahme dynamischer Belastungen ermöglicht. Die Kopfplatte lässt sich einfach herstellen, indem zunächst eine Bohrung eingebracht wird und dann die Kugelpfanne ausgefräst wird. In diese Kugelpfanne wird von oben die Mutter mit dem Kugelkopf durchgeführt, der verbreitert ausgeführt ist und in der Kugelpfanne beweglich zu liegen kommt. In das Innengewinde der Mutter wird anschließend ein Außengewinde der Stange eingeschraubt, sodass die Verbindung rasch, aber dennoch dauerhaft stabil hergestellt ist. Durch die Ausbildung einer Kugelpfanne und eines hierzu korrespondierenden verbreiterten Kugelkopfes an der Mutter ergibt sich eine Lagerung, welche eine Auslenkung der Mutter ermöglicht. Hierfür ist vorgesehen, dass die Mutter einen Abstand zur Bohrung aufweist. Über diesen Abstand, der durch einen inneren Durchmesser der Bohrung vorbestimmt wird, lässt sich ein maximaler Auslenkungswinkel einstellen, der in der Regel mit maximal 10° und üblicherweise von 3° bis 7° bemessen ist.It is particularly preferred that the top plate is formed with a bore and an adjoining ball socket. In this case, it is particularly possible that a nut is provided with a widened ball head and an internal thread into which an external thread of the rod is screwed, wherein the ball head is mounted in the ball socket of the top plate. These constructive measures results in a device that can be produced in a simple manner, but at the same time with a suitable design also similar to a joint flexibility and thus a constraint-free compensation situation-related deviations from a solder layer and the inclusion of dynamic loads. The headstock is easy to make by first inserting a hole and then milling out the ball socket. In this ball socket, the mother is performed with the ball head from above, which is widened and comes to rest in the ball socket movable. In the internal thread of the nut, an external thread of the rod is then screwed in, so that the connection is made quickly but permanently stable. The formation of a ball socket and a widened ball head corresponding thereto to the nut results in a bearing which allows a deflection of the nut. For this purpose, it is provided that the nut has a distance from the bore. About this distance, which is predetermined by an inner diameter of the bore, a maximum deflection angle can be adjusted, which is usually measured with a maximum of 10 ° and usually from 3 ° to 7 °.

An einem zweiten Ende, das der Kopfplatte gegenüberliegt, nimmt die Stange eine Ankerplatte auf. Die Befestigung der Ankerplatte an der Stange kann auf beliebige Art erfolgen. Besonders einfach ist es, dass die Ankerplatte mit der Stange verschraubt ist. Hierfür ist an der Stange am zweiten Ende ein entsprechendes Außengewinde vorgesehen, wohingegen die Ankerplatte ein korrespondierendes Innengewinde aufweist. Möglich ist es, dass auch die Ankerplatte mit einer Bohrung und einer anschließenden Kugelpfanne sowie einer Mutter ausgebildet ist, und zwar analog, wie dies vorstehend für die Kopfplatte beschrieben wurde, wobei die Ausrichtung der Mutter aber nach oben bzw. zur Firste hin erfolgt. Je nach Einbausituation kann dann die Ankerplatte anstelle der Kopfplatte mit entsprechender Ausbildung vorgesehen sein, um Auslenkungen zu ermöglichen. Möglich ist es auch, dass sowohl die Kopfplatte als auch die Ankerplatte bzw. Fußplatte mit einer Bohrung und Kugelpfanne ausgebildet und mit einer eingesetzten Mutter versehen sind. Dies erlaubt die größte Flexibilität.At a second end opposite the head plate, the rod receives an anchor plate. The attachment of the anchor plate to the rod can be done in any way. It is particularly easy that the anchor plate is bolted to the rod. For this purpose, a corresponding external thread is provided on the rod at the second end, whereas the anchor plate has a corresponding internal thread. It is possible that the anchor plate is formed with a bore and a subsequent ball socket and a nut, and analogously, as described above for the top plate, the alignment of the nut but up or to the ridge out. Depending on the installation situation, the anchor plate can then be provided instead of the top plate with appropriate training to deflections enable. It is also possible that both the top plate and the anchor plate or base plate are formed with a bore and ball socket and provided with an inserted nut. This allows the greatest flexibility.

In einer besonders einfachen Ausführungsvariante besteht die Vorrichtung aus der Kopfplatte, der Stange und der Ankerplatte sowie optional der Mutter, wobei gegebenenfalls die Stange mit einer Spannhülse ausgebildet sein kann, wenn die Kopfplatte an einer Firste und die Ankerplatte an einer bereits bestehenden Zwischendecke befestigt werden soll, wie dies bei Sanierungen häufig der Fall ist.In a particularly simple embodiment, the device consists of the top plate, the rod and the anchor plate and optionally the mother, where appropriate, the rod may be formed with a clamping sleeve when the top plate to a roof and the anchor plate to be attached to an existing false ceiling as is often the case with refurbishments.

Entsprechend den vorstehend dargelegten Vorteilen findet eine erfindungsgemäße Vorrichtung bevorzugt Verwendung zur abgehängten Befestigung einer Zwischendecke an einer Firste eines Tunnels.In accordance with the advantages set out above, a device according to the invention is preferably used for the suspended attachment of an intermediate ceiling to a roof of a tunnel.

Aufgrund der dargestellten Vorteile ergibt sich des Weiteren, dass eine abgehängte Zwischendecke eines Tunnels mit Vorteil eine erfindungsgemäße Vorrichtung umfasst, wobei die Ankerplatte von der Zwischendecke eingeschlossen oder an dieser befestigt ist. Demgemäß kann nach der Erfindung ein Tunnel mit einer Firste und einer Zwischendecke, die mit Verbindungsmitteln an der Firste gehalten ist, mit Verbindungsmitteln ausgebildet sein, die zumindest teilweise als erfindungsgemäße Vorrichtung ausgebildet sind.Due to the advantages shown, it is also clear that a suspended false ceiling of a tunnel advantageously comprises a device according to the invention, wherein the anchor plate is enclosed by or secured to the false ceiling. Accordingly, according to the invention, a tunnel with a roof and a false ceiling, which is held with connecting means on the roof, be formed with connecting means, which are at least partially formed as a device according to the invention.

Correspondingly, a nut 14 is provided with a widened executed ball head 15. After preparation of the bore 12 and the ball socket 13 in the top plate 5, the nut 14 is inserted with the ball head 15 from above into the top plate 5, so that the ball head 15, the in Fig. 2 can be seen in detail, in the ball socket 13, the in Fig. 3 can be seen in detail, comes to rest. Subsequently, the rod 8, which has an external thread 11 at a first end 9, in an in Fig. 2 indicated internal thread 16 of the nut 14 is screwed. At a second end 10, the anchor plate 7 is attached. This attachment can be done in any way, but preferably this is the rod 8 at the second end 10 also formed with an external thread, so that a trained with a corresponding internal thread anchor plate 7 can be screwed.

Bei der Montage bzw. Verbauung der Vorrichtung 1 wird diese zunächst wie vorstehend beschrieben zusammengestellt. Anschließend wird die Kopfplatte 5 mit Befestigungsmitteln 6 an der Firste 3 befestigt. Dies erfolgt vorzugsweise so, dass die Kopfplatte 5 an der Firste 3 zur Anlage kommt. Nach Montage einer Vielzahl von entsprechenden Vorrichtungen 1 in einem Bereich einer einzuziehenden Zwischendecke 4 kann diese schließlich um die Ankerplatten 7 herum betoniert werden. Ist eine Vielzahl von Vorrichtungen 1 vorgesehen, so kann die Zwischendecke 4 entsprechend dünn und damit materialsparend betoniert werden, ohne Einschränkungen in Bezug auf eine Belastbarkeit hinnehmen zu müssen.During assembly or obstruction of the device 1, this is first assembled as described above. Subsequently, the top plate 5 is fastened with fastening means 6 on the ridge 3. This is preferably done so that the top plate 5 comes to the ridges 3 to the plant. After mounting a plurality of corresponding devices 1 in a region of an intermediate ceiling 4 to be recovered, this can finally be concreted around the anchor plates 7 around. If a plurality of devices 1 are provided, the intermediate ceiling 4 can be correspondingly thin and thus concreted in a material-saving manner, without having to accept any restrictions with respect to a load capacity.

Wie aus Fig. 1 ersichtlich ist, ist ein innerer Durchmesser der Bohrung 12 größer dimensioniert als ein äußerer Durchmesser der Mutter 14. Dadurch ist ein Spiel zwischen den Rändern der Bohrung 12 und einer äußeren Oberfläche der Mutter 14 gegeben, sodass die Mutter 14 im Zusammenspiel mit der Lagerung des Kugelkopfes 15 in der Kugelpfanne 13 in vorbestimmter Weise auslenkbar ist. Die maximale Auslenkbarkeit ergibt sich dabei durch das vorgegebene Spiel. Es ist somit möglich, die maximale Auslenkbarkeit in Bezug auf erwartete dynamische Belastungen, primär aber zum Ausgleich von Einbauungenauigkeiten ohne Zwängungen auszulegen, wie dies in Fig. 4 für einen Winkel von 6° dargestellt ist. Üblicherweise wird ein maximaler Auslenkungswinkel mit weniger als 10° festgelegt, obwohl grundsätzlich auch größere Winkel möglich wären. Übliche Winkelbereiche liegen im Bereich von 3° bis 7°. Selbst bei kaum vermeidbaren Einbauungenauigkeiten kann dadurch erreicht werden, dass die Stange 8 zumindest überwiegend nur auf Zug, aber nicht oder zumindest weniger auf Biegung beansprucht wird.How out Fig. 1 As can be seen, an inner diameter of the bore 12 is larger than an outer diameter of the nut 14. Thereby a clearance between the edges of the bore 12 and an outer surface of the nut 14 is given, so that the nut 14 in conjunction with the bearing of the ball head 15 in the ball socket 13 is deflected in a predetermined manner. The maximum deflectability results from the given game. It is thus possible the maximum Deflectability in relation to expected dynamic loads, but primarily to compensate for installation inaccuracies without constraints, as in Fig. 4 is shown for an angle of 6 °. Typically, a maximum deflection angle is set to less than 10 °, although in principle larger angles would be possible. Usual angular ranges are in the range of 3 ° to 7 °. Even with hardly avoidable installation inaccuracies can be achieved that the rod 8 is at least predominantly only on train, but not or at least less subject to bending.

Die in Fig. 1 und 4 dargestellte Einbausituation der Vorrichtungen 1 entspricht jenen Bereichen, in denen die Firste 3 horizontal oder zumindest annähernd horizontal verläuft. Vor allem bei stärkerer Neigung der Firste 3 in einem seitlichen Bereich kann es aber erforderlich sein, die Vorrichtung 1 geneigt zu befestigen. Entsprechende Einbausituationen sind in Fig. 5 und 6 dargestellt, wobei bei Bedarf wiederum ein Spiel zwischen einem inneren Durchmesser der Bohrung 12 und einem äußeren Durchmesser der Mutter 14 vorgesehen sein kann, sodass die Vorrichtung 1 gemäß Fig. 5 auslenkbar ist, wie dies in Fig. 6 ersichtlich ist. Dies kann auf einfache Weise erreicht werden, wenn die Kugelpfanne 13 mit der daran anschließenden Bohrung 12 in der Kopfplatte 5 geneigt angeordnet ist. Ein Neigungswinkel wird dabei auf die Einbausituation angepasst.In the Fig. 1 and 4 illustrated installation situation of the devices 1 corresponds to those areas in which the ridges 3 is horizontal or at least approximately horizontal. Especially with a stronger inclination of the roofs 3 in a lateral area, it may be necessary to fasten the device 1 inclined. Corresponding installation situations are in Fig. 5 and 6 represented, where necessary, in turn, a clearance between an inner diameter of the bore 12 and an outer diameter of the nut 14 may be provided, so that the device 1 according to Fig. 5 is deflectable, as is in Fig. 6 is apparent. This can be achieved in a simple manner when the ball socket 13 is arranged inclined with the adjoining bore 12 in the top plate 5. An inclination angle is adapted to the installation situation.

Im Rahmen der Erfindung sind auch noch einfachere Ausbildungen einer Vorrichtung 1 möglich. Für besonders einfache Systeme kann vorgesehen sein, dass die Kopfplatte 5 im Bereich der Bohrung 12 bloß ein Innengewinde aufweist, auf eine Kugelpfanne 13 allerdings verzichtet wird. In diesem Fall wird die Stange 8 mit dem Außengewinde 11 im Bereich des ersten Endes 9 der Stange 8 unmittelbar in der Kopfplatte 5 fixiert. Eine derartige Ausführungsvariante eignet sich dann, wenn auf eine gelenkige Lagerung mit der Kugelpfanne 13 und dem Kugelkopf 15 verzichtet werden kann.In the context of the invention even simpler embodiments of a device 1 are possible. For particularly simple systems can be provided that the top plate 5 in the region of the bore 12 has only an internal thread, however, a ball socket 13 is dispensed with. In this case, the rod 8 is fixed with the external thread 11 in the region of the first end 9 of the rod 8 directly in the top plate 5. Such a variant is suitable when it can be dispensed with an articulated mounting with the ball socket 13 and the ball head 15.

In anderen Varianten kann anstelle der Kopfplatte 5 die Ankerplatte 7 zur gelenkigen Aufnahme ausgebildet sein. Möglich ist es auch, dass sowohl die Kopfplatte 5 als auch die Ankerplatte 7 entsprechend ausgebildet sind.In other variants, instead of the top plate 5, the anchor plate 7 may be formed for articulated reception. It is also possible that both the top plate 5 and the anchor plate 7 are formed accordingly.

Möglich ist es für bestimmte Anwendungsfälle auch, dass die Kopfplatte 5 durch eine Ankerstange ersetzt wird, die über einem Dübel in der Firste 3 gehalten wird.It is also possible for certain applications that the top plate 5 is replaced by an anchor rod which is held over a dowel in the roof 3.
