Definitions
- the invention relates to a hanger for suspended ceilings, which have a supporting frame made of profiled rails and a layer of insulating plates supported by them; with a vertical hanging part extending through the position of insulating plates, which has a widened holding part at its lower end, on which at least one recess is recessed for connection to the profile rail.
- Such hangers are usually made of sheet metal and are used to hang the profile rails belonging to the supporting structure of a suspended suspended ceiling from the bare ceiling or another ceiling construction, for example ceiling beams.
- connection between the hanger and the profile rail is made by positive engagement. If - as in most cases - the profile rails are C-profile rails, then there are recesses on the two opposite edges of the usually flat, sheet-metal holding part, in which the mutually facing flanges of the C-profile rail engage.
- profile rails are T-rails, the one after them have a bead, then this bead is received and carried in an upwardly widening incision of the holding part.
- the supporting structure of the suspended ceiling can be covered, for example, with plasterboard, which form the lower surface of the ceiling.
- plasterboard which form the lower surface of the ceiling.
- a layer of insulating panels for example mineral fiber panels, is provided, which lies on the supporting frame. The hangers for the supporting frame must therefore extend through this layer of insulating plates.
- the false ceiling is usually installed from below because the space between the false ceiling and the bare ceiling is not accessible or is difficult to access.
- the individual or several hangers must first be pushed through the position of insulating plates before the profile rails are connected to the holding parts of the hangers.
- a particular difficulty for the fitter is that the insulating plates must be held up until the connection between the holding parts of the hangers and the profile rails is established. Since the fitter needs both hands for this connection, he has to support the insulating plates with his shoulder, for example, to prevent it from sinking before the profile rail is attached. This process is exhausting and labor intensive.
- the object of the invention is therefore to provide a hanger of the type mentioned, with which the insulating plates can be preassembled in a simple manner and with little effort, so that they are already held in their predetermined position when the mounting rails are mounted.
- the holding part protrudes through a central opening of a horizontal support plate, that after a rotation about the longitudinal axis of the hanger part with two opposite edge sections of its central opening, the support plate engages in opposite edge recesses of the holding part and in that the edge recesses of the Retaining part engaging edge portions of the support plate each have a rising inclined surface, preferably in both directions of rotation.
- the insulating plate After the holding part of the hanger has been inserted through the insulating plate, the insulating plate is held by the supporting plate, so that the insulating plate cannot sink while the profile rail is being attached.
- the attachment of the support plate is carried out in a simple and quick manner in that the holding part of the hanger is inserted into the central opening of the support plate and the support plate is then rotated, whereby it engages with edge sections of its central opening in the edge recesses provided for this purpose in the holding part, so that a positive connection is established.
- the support plate By running onto the inclined surfaces, the support plate is secured against the holding part of the suspension.
- the inclined surface ends at an angular distance from a rotary stop, which limits the possible rotational movement of the support plate with respect to the holding part.
- the support plate is rotated until the edge recesses of the holding part are the inclined surface have overcome and click into place.
- the rotation stop prevents further rotation.
- the support plate is positively locked in its outermost rotational position on the holding part of the suspension.
- the suspended ceiling shown in FIG. 1 has a supporting structure with profile rails 1, which in the exemplary embodiment shown are designed as C-profile rails.
- Gypsum plasterboards 2 are attached to the profile rails 1 and cover the underside of the ceiling form.
- the profile rails 1 are suspended from a ceiling structure by a plurality of hangers 3 (only one hanger 3 of which is shown in FIG. 1), of which a wooden truss 4 is shown in FIG. 1, to which the hanger 3 is screwed.
- insulating plates 5 for example mineral fiber plates, which bring about thermal and acoustic insulation of the suspended ceiling.
- the hanger 3 (Fig. 2) has a substantially flat, vertical, elongated hanger part 6, which is provided at its lower end with a widened, also substantially flat holding part 7, which are made in one piece.
- the holding part 7 each has a latching recess 9.
- the two mutually facing flanges 1 a of the profile rail 1 engage in the two latching recesses 9.
- lateral edge recesses 10 in the form of incisions or notches are provided on the two edges 8 of the holding part 7.
- the holding part 7 protrudes through a central opening 11 of a substantially flat, horizontal support plate 12 made of sheet metal provided radially outwardly extending notches or slots 13.
- edge sections 14 of the opening 11 which, after the support plate 12 has been rotated about the longitudinal axis of the hanging part 6, into the two opposite ones Engage edge recesses 10 of the holding part 7 in a form-fitting manner.
- edge sections 14 each have an increasing inclined surface 15 in both directions of rotation.
- Each inclined surface 15 forms a ramp on which the upper edge of the edge recess 10 runs.
- Opposing edge projections 16 projecting into the central opening 11 form rotary stops for the section of the holding part 7 projecting into the central opening 11. After a rotation of approximately 45 ° relative to the insertion position, the section of the holding part 7 projecting into the opening 11 comes to rest the two edge projections 16 so that further rotation is prevented. Since the inclined surfaces 15 each end at a small angular distance from the edge projections 16, which limit the possible rotational movement of the support plate 12 relative to the holding part 7 as a rotary stop, these two parts are fixed in their relative position to one another.
- the support plate 12 thus attached to the hanger 3 carries the insulating plate 5, so that the profile rail 1 can then be attached to the holding part 7 without hindrance.
- the support plate 12 made of sheet metal is reinforced in the area of the greatest radial expansion of the central opening 11, namely in the area of the slots 13, by beads 17 approximately parallel to the edge.
- the hanger part 6 made of sheet metal is also reinforced by beads 18 approximately parallel to the edge.
- both the beads 17 of the support plate 12 and the beads 18 of the suspension part 3 are designed as double beads, each consisting of two individual beads deformed in opposite directions from the plane of the sheet metal, the one bead directly in a transition section rising to the other bead merges into the other bead. This results in a particularly effective stiffening, in particular in the edge region, of the parts made of relatively thin sheet metal, namely the support plate 12 and the hanger part 6.
- FIGS. 1 and 2 show an embodiment of the hanger 3 which is modified compared to FIGS. 1 and 2.
- a hanger rail 19 with a U-shaped cross section is attached to the hanger part 6, which is shorter than the previously described hanger part, but otherwise in the same way , preferably riveted, which has rows of holes 20.
- a height-adjustable vernier connection is created.
- the modified hanger part shown in FIG. 5 differs from the hanger part 3 according to FIG. 2 essentially only in that the holding part 7 has an incision 22 starting from its lower edge 21 and widening in its upper region. This incision 22 is intended for receiving a bead 23 of a T-profile rail 24, which is only indicated with dash-dotted lines in FIG. 5.
Abstract
Description
Die Erfindung betrifft einen Abhänger für Unterdecken, die ein Traggerippe aus Profilschienen und eine von diesen getragene Lage von Isolierplatten aufweisen; mit einem senkrechten, sich durch die Lage von Isolierplatten erstreckenden Abhängerteil, das an seinem unteren Ende ein verbreitertes Halteteil aufweist, an dem mindestens eine Rastausnehmung zur Verbindung mit der Profilschiene ausgespart ist.The invention relates to a hanger for suspended ceilings, which have a supporting frame made of profiled rails and a layer of insulating plates supported by them; with a vertical hanging part extending through the position of insulating plates, which has a widened holding part at its lower end, on which at least one recess is recessed for connection to the profile rail.
Derartige Abhänger werden üblicherweise aus Blech hergestellt und dienen dazu, die zum Traggerippe einer abhängten Unterdecke gehörenden Profilschienen von der Rohdecke oder einer sonstigen Deckenkonstruktion, beispielsweise Deckenbalken, abzuhängen.Such hangers are usually made of sheet metal and are used to hang the profile rails belonging to the supporting structure of a suspended suspended ceiling from the bare ceiling or another ceiling construction, for example ceiling beams.
Die Verbindung zwischen dem Abhänger und der Profilschiene erfolgt durch formschlüssigen Eingriff. Wenn es sich - wie in den meisten Fällen - bei den Profilschienen um C-Profilschienen handelt, so sind an den beiden gegenüberliegenden Rändern des üblicherweise flachen, aus Blech bestehenden Halteteils Rastausnehmungen ausgespart, in die die gegeneinander gerichteten Flansche der C-Profilschiene eingreifen.The connection between the hanger and the profile rail is made by positive engagement. If - as in most cases - the profile rails are C-profile rails, then there are recesses on the two opposite edges of the usually flat, sheet-metal holding part, in which the mutually facing flanges of the C-profile rail engage.
Wenn die Profilschienen T-Schienen sind, die an ihrem nach oben ragenden Steg einen Wulst aufweisen, dann wird dieser Wulst in einem sich nach oben verbreiternden Einschnitt des Halteteils aufgenommen und getragen.If the profile rails are T-rails, the one after them have a bead, then this bead is received and carried in an upwardly widening incision of the holding part.
Das Traggerippe der Unterdecke kann beispielsweise mit Gipskartonplatten beplankt sein, die die untere Deckenfläche bilden. Zur Wärme- und/oder Schalldämmung ist eine Lage von Isolierplatten, beispielsweise Minderalfaserplatten, vorgesehen, die auf dem Traggerippe liegt. Die Abhänger für das Traggerippe müssen sich daher durch diese Lage von Isolierplatten hindurcherstrecken.The supporting structure of the suspended ceiling can be covered, for example, with plasterboard, which form the lower surface of the ceiling. For thermal and / or sound insulation, a layer of insulating panels, for example mineral fiber panels, is provided, which lies on the supporting frame. The hangers for the supporting frame must therefore extend through this layer of insulating plates.
Die Montage der Unterdecke erfolgt üblicherweise von unten, weil der zwischen der Unterdecke und der Rohdecke liegende Raum nicht oder nur schwierig zugänglich ist. Hierbei müssen die einzelnen oder mehrere Abhänger zunächst durch die Lage von Isolierplatten hindurchgesteckt werden, bevor die Profilschienen mit den Halteteilen der Abhänger verbunden werden. Für den Monteur besteht eine besondere Schwierigkeit darin, daß die Isolierplatten hochgehalten werden müssen, bis die Verbindung zwischen den Halteteilen der Abhänger und den Profilschienen hergestellt ist. Da der Monteur für diese Verbindung beide Hände braucht, muß er die Isolierplatten beispielsweise mit der Schulter abstützen, um ein Absinken zu verhindern, bevor die Profilschiene angebracht ist. Dieser Arbeitsvorgang ist anstrengend und arbeitsaufwendig.The false ceiling is usually installed from below because the space between the false ceiling and the bare ceiling is not accessible or is difficult to access. The individual or several hangers must first be pushed through the position of insulating plates before the profile rails are connected to the holding parts of the hangers. A particular difficulty for the fitter is that the insulating plates must be held up until the connection between the holding parts of the hangers and the profile rails is established. Since the fitter needs both hands for this connection, he has to support the insulating plates with his shoulder, for example, to prevent it from sinking before the profile rail is attached. This process is exhausting and labor intensive.
Bei einem bekannten Abhänger der eingangs genannten Gattung (EP-A-0 319 390) sind seitlich neben dem zur Verbindung mit den Profilschienen bestimmten Halteteil zwei Flügel hochbiegbar angeordnet, um die Isolierplatten bei der Montage zu tragen. Die Tragkraft dieser Flügel ist jedoch sehr gering und hängt von der Dicke des verwendeten Blechs ab. Wenn die abgewinkelten Flügel eine höhere Tragkraft haben sollen, ist auch die zum Umbiegen erforderliche Kraft erhöht, wodurch der Arbeitsaufwand bei der Montage vergrößert wird. Bei einer nachträglichen Demontage der Isolierplatten besteht die Gefahr einer Beschädigung der Isolierplatten, weil die Flügel nicht wieder vollständig in ihre ursprüngliche gestreckte glatte Lage zurückgebogen werden können.In a known hanger of the type mentioned at the beginning (EP-A-0 319 390), two wings are arranged laterally next to the holding part intended for connection to the profiled rails, so as to be able to bend the insulating plates during assembly. However, the load capacity of these wings is very low and depends on the thickness of the sheet used. If the angled wings are higher Should have load capacity, the force required for bending is increased, which increases the amount of work involved in assembly. If the insulating plates are subsequently removed, there is a risk of damage to the insulating plates because the wings cannot be completely bent back into their original, straight, smooth position.
Bei einem anderen bekannten Abhänger (DE-B-10 56 349), der zur Befestigung an einer Rohbaudecke bestimmt ist, sind entlang dem Abhängerteil mehrere gegenüberliegende Kantenausnehmungen vorgesehen, in die eine waagerechte Tragplatte mit Randabschnitten ihrer zentralen Öffnungen eingreift. Das untere Ende des Halteteils ist längsgeschlitzt. Die dadurch gebildeten beiden Schenkel können in entgegengesetzten Richtungen umgebogen werden, um ebenfalls ein Halteteil für eine Isolierplatte zu bilden. Dieser bekannte Abhänger ist dazu bestimmt, mehrere Isolierplatten übereinander zu tragen, ohne daß ein Traggerippe aus Profilschienen angebracht wird. Die waagerechten Tragplatten dienen hierbei zur endgültigen Aufnahme der Isolierplatten.In another known hanger (DE-B-10 56 349), which is intended for fastening to a structural ceiling, several opposite edge recesses are provided along the hanger part, into which a horizontal support plate engages with edge sections of its central openings. The lower end of the holding part is slotted lengthways. The two legs formed in this way can be bent in opposite directions in order to likewise form a holding part for an insulating plate. This known hanger is intended to carry several insulating plates one above the other without a supporting frame made of profiled rails being attached. The horizontal support plates serve to finally hold the insulation plates.
Aufgabe der Erfindung ist es daher, einen Abhänger der eingangs genannten Gattung zu schaffen, mit dem in einfacher Weise und mit geringem Aufwand eine Vormontage der Isolierplatten ermöglicht wird, so daß diese schon in ihrer vorgegebenen Lage gehalten werden, wenn die Profilschienen montiert werden.The object of the invention is therefore to provide a hanger of the type mentioned, with which the insulating plates can be preassembled in a simple manner and with little effort, so that they are already held in their predetermined position when the mounting rails are mounted.
Diese Aufgabe wird erfindugnsgemäß dadurch gelöst, daß das Halteteil durch eine zentrale Öffnung einer waagerechten Tragplatte ragt, daß die Tragplatte nach einer Verdrehung um die Längsachse des Abhängerteils mit zwei gegenüberliegenden Randabschnitten seiner zentrale Öffnung in gegenüberliegende Kantenausnehmungen des Halteteils eingreift und daß die in die Kantenausnebmungen des Halteteils eingreifenden Randabschnitte der Tragplatte jeweils eine ansteigende Schrägfläche aufweisen, und zwar vorzugsweise nach beiden Drehrichtungen.This object is achieved in accordance with the invention in that the holding part protrudes through a central opening of a horizontal support plate, that after a rotation about the longitudinal axis of the hanger part with two opposite edge sections of its central opening, the support plate engages in opposite edge recesses of the holding part and in that the edge recesses of the Retaining part engaging edge portions of the support plate each have a rising inclined surface, preferably in both directions of rotation.
Nachdem das Halteteil des Abhängers durch die Isolierplatte gesteckt wurde, wird die Isolierplatte durch die Tragplatte gehalten, so daß die Isolierplatte während des Anbringens der Profilschiene nicht absinken kann.After the holding part of the hanger has been inserted through the insulating plate, the insulating plate is held by the supporting plate, so that the insulating plate cannot sink while the profile rail is being attached.
Die Anbringung der Tragplatte erfolgt in einfacher und schneller Weise dadurch, daß das Halteteil des Abhängers in die zentrale Öffnung der Tragplatte eingeführt und die Tragplatte anschließend verdreht wird, wobei sie mit Randabschnitten ihrer zentralen Öffnung in die hierfür vorgesehenen Kantenausnehmungen des Halteteils eingreift, so daß eine formschlüssige Verbindung hergestellt wird.The attachment of the support plate is carried out in a simple and quick manner in that the holding part of the hanger is inserted into the central opening of the support plate and the support plate is then rotated, whereby it engages with edge sections of its central opening in the edge recesses provided for this purpose in the holding part, so that a positive connection is established.
Durch das Auflaufen auf die Schrägflächen erfolgt eine Klemmsicherung der Tragplatte am Halteteil des Abhängers.By running onto the inclined surfaces, the support plate is secured against the holding part of the suspension.
Dadurch erfolgt eine Verriegelung der Tragplatte in ihrer gedrehten Stellung.This locks the support plate in its rotated position.
Vorzugsweise ist vorgesehen daß die Schrägfläche jeweils in einem Winkelabstand vor einem Drehanschlag endet, der die nögliche Drehbewegung der Tragplatte gegenüber dem Halteteil begrenzt. Hierbei wird die Tragplatte so weit gedreht, bis die Kantenausnehmungen des Halteteils die Schrägfläche überwunden haben und dahinter einrasten. Eine weitere Drehung wird durch den Drehanschlag verhindert. Im Gegensatz zu einer bloßen Verklemmung der Kantenausnehmungen an den Schrägflächen wird hierbei eine formschlüssige Verrastung der Tragplatte in ihrer äußersten Drehstellung am Halteteil des Abhängers bewirkt.It is preferably provided that the inclined surface ends at an angular distance from a rotary stop, which limits the possible rotational movement of the support plate with respect to the holding part. Here, the support plate is rotated until the edge recesses of the holding part are the inclined surface have overcome and click into place. The rotation stop prevents further rotation. In contrast to a mere jamming of the edge recesses on the inclined surfaces, the support plate is positively locked in its outermost rotational position on the holding part of the suspension.
Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments of the inventive concept are the subject of further dependent claims.

Die in Fig. 1 in einem Ausschnitt dargestellte Unterdecke weist ein Traggerippe mit Profilschienen 1 auf, die bei dem dargestellten Ausführungsbeispiel als C-Profilschienen ausgeführt sind. An den Profilschienen 1 sind Gipskartonplatten 2 angebracht, die die Deckenunterseite bilden. Die Profilschienen 1 sind durch mehrere Abhänger 3 (von denen in Fig. 1 nur ein Abhänger 3 dargestellt ist) von einer Deckenkonstruktion abgehängt, von der in Fig. 1 beispielsweise ein Holzbinder 4 dargestellt ist, an dem der Abhänger 3 angeschraubt ist.The suspended ceiling shown in FIG. 1 has a supporting structure with profile rails 1, which in the exemplary embodiment shown are designed as C-profile rails.
Auf dem aus den Profilschienen 1 bestehenden Traggerippe ruht eine Lage von Isolierplatten 5, beispielsweise Mineralfaserplatten, die eine Wärme- und Schallisolierung der Unterdecke bewirken.On the support structure consisting of the profiled rails 1 there is a layer of
Der Abhänger 3 (Fig. 2) weist ein im wesentlichen flaches, senkrechtes, längliches Abhängerteil 6 auf, das an seinem unteren Ende mit einem verbreiterten, ebenfalls im wesentlichen flachen Halteteil 7 versehen ist, die einstückig ausgeführt sind.The hanger 3 (Fig. 2) has a substantially flat, vertical,
An seinen beiden gegenüberliegenden Rändern 8 hat das Halteteil 7 jeweils eine Rastausnehmung 9. In die beiden Rastausnehmungen 9 greifen die beiden gegeneinander gerichteten Flansche 1a der Profilschiene 1 ein.At its two
Oberhalb der beiden Rastausnehmungen 9 sind an den beiden Rändern 8 des Halteteils 7 seitliche Kantenausnehmungen 10 in Form von Einschnitten oder Kerben vorgesehen.Above the two
Im montierten Zustand (Fig. 1) ragt das Halteteil 7 durch eine zentrale Öffnung 11 einer aus Blech bestehenden, im wesentlichen flachen, waagerechten Tragplatte 12. Um das Einführen des Halteteils 7 zu ermöglichen, ist die zentrale Öffnung 11 an zwei gegenüberliegenden Stellen mit sich radial nach außen erstreckenden Kerben oder Schlitzen 13 versehen. Beiderseits davon liegen jeweils Randabschnitte 14 der Öffnung 11, die nach einer Verdrehung der Tragplatte 12 um die Längsachse des Abhängerteils 6 in die beiden gegenüberliegenden Kantenausnehmungen 10 des Halteteils 7 formschlüssig eingreifen. Diese Randabschnitte 14 weisen ausgehend von den Schlitzen 13 nach beiden Drehrichtungen jeweils eine ansteigende Schrägfläche 15 auf. Jede Schrägfläche 15 bildet eine Rampe, auf die die Oberkante der Kantenausnehmung 10 aufläuft.In the assembled state (FIG. 1), the
In die zentrale Öffnung 11 ragende, einander gegenüberliegende Randvorsprünge 16 bilden Drehanschläge für den in die zentrale Öffnung 11 ragenden Abschnitt des Halteteils 7. Nach einer Drehung von ungefähr 45° gegenüber der Einführungsstellung kommt der in die Öffnung 11 ragende Abschnitt des Halteteils 7 zur Anlage an den beiden Randvorsprüngen 16, so daß eine weitere Drehung verhindert wird. Da die Schrägflächen 15 jeweils in einem geringen Winkelabstand vor den Randvorsprüngen 16 enden, die als Drehanschlag die mögliche Drehbewegung der Tragplatte 12 gegenüber dem Halteteil 7 begrenzen, sind diese beiden Teile in ihrer Relativstellung zueinander festgelegt.
Die so am Abhänger 3 angebrachte Tragplatte 12 trägt die Isolierplatte 5, so daß die Profilschiene 1 anschließend unbehindert am Halteteil 7 angebracht werden kann.The
Die aus Blech bestehende Tragplatte 12 ist im Bereich der größten radialen Ausdehnung der zentralen Öffnung 11, nämlich im Bereich der Schlitze 13, durch angenähert randparallele Sicken 17 verstärkt. Auch das aus Blech bestehende Abhängerteil 6 ist durch angenähert randparallele Sicken 18 verstärkt. Bei dem dargestellten Ausführungsbeispiel sind sowohl die Sicken 17 der Tragplatte 12 als auch die Sicken 18 des Abhängerteils 3 als Doppelsicken ausgeführt, die jeweils aus zwei in entgegengesetzten Richtungen aus der Blechebene verformte einzelne Sicken bestehen, wobei die eine Sicke unmittelbar in einem zur anderen Sicke ansteigenden Übergangsabschnitt in die andere Sicke übergeht. Dadurch wird eine besonders wirksame Versteifung, insbesondere im Randbereich, der aus verhältnismäßig dünnem Blech hergestellten Teile, nämlich der Tragplatte 12 und des Abhängerteils 6 erreicht.The
Fig. 4 zeigt eine gegenüber den Fig. 1 und 2 abgewandelte Ausführungsform des Abhängers 3. Hierbei ist an dem Abhängerteil 6, das kürzer als das vorher beschriebene Abhängerteil, jedoch sonst in gleicher Weise ausgeführt ist, eine im Querschnitt U-förmige Abhängerschiene 19 angebracht, vorzugsweise angenietet, die Lochreihen 20 aufweist. Mit einem entsprechend gelochten (nicht dargestellten) oberen Abhängerteil wird damit eine höhenverstellbare Nonius-Verbindung geschaffen.4 shows an embodiment of the
Das in Fig. 5 gezeigte abgewandelte Abhängerteil unterscheidet sich vom Abhängerteil 3 nach Fig. 2 im wesentlichen nur dadurch, daß das Halteteil 7 einen von seiner Unterkante 21 ausgehenden, in seinem oberen Bereich verbreiterten Einschnitt 22 aufweist. Dieser Einschnitt 22 ist zur Aufnahme eines Wulstes 23 einer T-Profilschiene 24 bestimmt, die in Fig. 5 mit strichpunktierten Linien nur angedeutet ist.The modified hanger part shown in FIG. 5 differs from the
Man erkennt aus Fig. 5, daß die beiden die Tragplatte 12 aufnehmenden Kantenausnehmungen 10 oberhalb des Einschnitts 22 angeordnet sind, so daß auch hier - ebenso wie beim vorher beschriebenen Ausführungsbeispiel - die Tragplatte 12 jeweils oberhalb der Profilschiene 1 bzw. 24 liegt und deshalb deren Montage nicht behindert.It can be seen from FIG. 5 that the two edge recesses 10 receiving the
