Lateral carrying portions (13), which are arranged at a distance from the cross-piece portions (8), carry the edge strips (4) of the C-shaped profile (1). The hanger (5) is, in the mounted, vertical state, positively connected to the C-shaped profile (1) and lies flat on its outside, so that it does not hinder the introduction of insulating material next to and above the carrying rail (1). <IMAGE>

Description

Die Erfindung betrifft einen Abhänger für C-Profilschienen für Unterdecken, bei denen die obenliegende Öffnung der C-Profilschiene durch zwei nach innen gerichtete Randstreifen begrenzt wird, mit einem nach oben ragenden Abhängeroberteil und einem damit verbundenen, unter die Randstreifen des C-Profils greifenden Abhängerunterteil, das ein sich quer über die C-Profilschiene erstreckendes und deren obere Ränder übergreifendes Querstück aufweist, gegenüber dem untere, seitliche Traglaschen in Längsrichtung der C-Profilschiene versetzt angeordnet sind, die unter die Randstreifen der C-Profilschiene greifen, wobei das Querstück zwei an der Oberseite der C-Profilschiene liegende Querstückabschnitte mit jeweils einer nach unten abgewinkelten Endlasche aufweist, die jeweils den oberen Rand der C-Profilschiene übergreift und an der Außenseite der C-Profilschiene liegt.The invention relates to a hanger for C-profile rails for suspended ceilings, in which the overhead opening of the C-profile rail is delimited by two inwardly directed edge strips, with an upwardly hanging upper part of the hanger and an associated lower part which reaches under the edge strips of the C-profile , which has a cross piece extending across the C-profile rail and overlapping its upper edges, with respect to which the lower, lateral support straps are staggered in the longitudinal direction of the C-profile rail, which engage under the edge strips of the C-profile rail, with the cross piece at two the cross-piece sections lying on the top of the C-profile rail, each with an end tab angled downwards, which in each case overlaps the upper edge of the C-profile rail and lies on the outside of the C-profile rail.

Aus Blech bestehende C-Profilschienen werden in großem Umfang als Tragschienen von abgehängten Unterdecken verwendet. Die nach innen gerichteten Randstreifen sind im Querschnitt beispielsweise halbkreisförmig gekrümmt. Es ist bekannt (DE-GM 81 09 075), die für diese C-Profilschienen bestimmten Abhänger als umgekehrt T-förmige, im wesentlichen flache Blechteile auszubilden, die sich mit abgewinkelten horizontalen Laschen am Boden der C-Profilschiene abstützen. Dadurch wird zwar eine gewisse Drucksteifigkeit der Verbindung zwischen dem Abhänger und der C-Profilschiene erreicht; da die C-Profilschienen aber üblicherweise aus verhältnismäßig dünnem Blech hergestellt sind, besteht die Gefahr, daß sich die unteren Abhängeteile durch die Stegfläche der C-Profilschiene hindurch abzeichnen, was besonders unerwünscht ist, wenn die Unterseite der Stegfläche der C-Profilschiene an der Deckenunterseite sichtbar bleibt, wie dies bei vielen abgehängten Decken der Fall ist.C profile rails made of sheet metal are widely used as support rails for suspended ceilings. The inward-facing edge strips are curved, for example, in a semicircular cross section. It is known (DE-GM 81 09 075) to design the hangers intended for these C profile rails as an inverted T-shaped, essentially flat sheet metal parts which are supported with angled horizontal tabs on the bottom of the C profile rail. This does make one certain pressure rigidity of the connection between the hanger and the C-profile rail achieved; but since the C-profile rails are usually made of relatively thin sheet metal, there is a risk that the lower suspension parts will show through the land surface of the C-profile rail, which is particularly undesirable if the underside of the land surface of the C-profile rail is on the underside of the ceiling remains visible, as is the case with many suspended ceilings.

Bei einem Abhänger der eingangs genannten Gattung (DE-A 21 09 596) ist deshalb ein sich quer über die C-Profilschiene erstreckendes Querstück mit zwei Querstückabschnitten vorgesehen, das als senkrechte Platte ausgeführt ist, die in ihrer unteren Kante zwei Ausnehmungen aufweist, in die die oberen Ränder der C-Profilschiene ragen. Auch die an die Querstückabschnitte anschließenden Endlaschen an der Außenseite der C-Profilschiene liegen in der gleichen senkrechten Ebene wie das Querstück. Bei einer etwaigen Druckbelastung von unten stützt sich die C-Profilschiene mit ihren oberen Rändern in diesen Ausnehmungen des Querstücks ab. Das Querstück dieses bekannten Abhängers ragt aber nach oben und insbesondere zu den beiden Seiten hin über die C-Profilschiene hinaus. Dies kann sich insbesondere dann störend auswirken, wenn der Raum neben und über den C-Profilschienen des Traggerippes einer abgehängten Unterdecke Isoliermaterial zum Brand- und Schallschutz aufnehmen soll.In a hanger of the type mentioned (DE-A 21 09 596), therefore, a cross piece extending across the C-profile rail is provided with two cross-piece sections, which is designed as a vertical plate, which has two recesses in its lower edge into which the upper edges of the C profile rail protrude. The end flaps on the outside of the C-profile rail adjoining the crosspiece sections also lie in the same vertical plane as the crosspiece. In the event of a pressure load from below, the C-shaped rail is supported with its upper edges in these recesses in the crosspiece. The crosspiece of this known hanger protrudes upwards and in particular on both sides beyond the C-profile rail. This can have a disruptive effect, in particular, if the room next to and above the C-profile rails of the supporting structure of a suspended suspended ceiling is to accommodate insulating material for fire and noise protection.

Aufgabe der Erfindung ist es daher, einen Abhänger der eingangs genannten Gattung so auszubilden, daß er das Einbringen von Isoliermaterial od.dgl. nicht stört oder behindert.The object of the invention is therefore to design a hanger of the type mentioned in such a way that it or the like introducing insulating material. does not interfere or hinder.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden sich in Längsrichtung der C-Profilschiene erstreckenden Querstückabschnitte in einer horizontalen Ebene an der Oberseite der C-Profilschiene liegen und daß die Endlasche flach an der Außenseite entlang der C-Profilschiene liegt.This object is achieved in that the two crosspiece sections extending in the longitudinal direction of the C-profile rail lie in a horizontal plane on the top of the C-profile rail and that the end flap lies flat on the outside along the C-profile rail.

Das Querstück, das eine von unten wirkende Druckbelastung der C-Profilschiene aufnimmt und beispielsweise im Brandfall ein Aufweiten der oberen Ränder der C-Profilschiene verhindert, liegt flächig sowohl an der Oberseite wie an den Seitenflächen der C-Profilschiene und stört daher beim Einbringen von Isoliermaterial nicht. Insbesondere besteht keine Gefahr, daß die Isoliermatten an vorstehenden Kanten des Abhängers hängenbleiben oder daß durch vorstehende Teile des Abhängerunterteils eine glattflächige Anlage des Isoliermaterials an den C-Profilschienen verhindert wird. Eine solche glattflächige Anlage ist vor allem für einen wirksamen Brandschutz und Schallschutz wichtig.The crosspiece, which absorbs a pressure load from below of the C-profile rail and prevents the upper edges of the C-profile rail from expanding in the event of a fire, lies flat on both the top and the side surfaces of the C-profile rail and therefore interferes with the insertion of insulating material Not. In particular, there is no risk that the insulating mats get caught on protruding edges of the hanger or that a protruding part of the lower part of the hanger will prevent the insulating material from coming into contact with the C-profile rails. Such a smooth system is particularly important for effective fire protection and sound insulation.

Gemäß einer bevorzugten Ausführung der Erfindung ist vorgesehen, daß bei einem Abhänger der genannten Gattung mit einem im horizontalen Querschnitt U-förmigen Abhängeroberteil mit einer Stegfläche und zwei Flanschen diese beiden Flansche des Abhängeroberteils jeweils zur Seite hin in einen der horizontalen Querstückabschnitte übergehen. Dadurch wird nicht nur eine sehr günstige Krafteinleitung im Übergangsbereich, sondern auch eine glatte äußere Gestaltung erreicht, die eine dichte Anlage des Isoliermaterials ermöglicht. Vorzugsweise verläuft der Übergang vom Flansch des Abhängeroberteils in den Querstückabschnitt in einem Bogen.According to a preferred embodiment of the invention it is provided that in a hanger of the type mentioned with a U-shaped hanger in horizontal cross section with a web surface and two flanges, these two flanges of the hanger top each pass to the side in one of the horizontal cross-section sections. This not only achieves a very favorable introduction of force in the transition area, but also a smooth outer design, which enables the insulating material to fit tightly. The transition from the flange of the upper hanger part into the crosspiece section preferably runs in an arc.

Im Gegensatz zu dem bekannten Abhänger, der ein bloßes Biegeteil ist, stellt der erfindungsgemäße Abhänger ein Formteil dar, bei dessen Formgebung ein Fließen des Blechmaterials nach Art eines Tiefziehvorgangs erfolgt. Ein solches Blechformteil ist gegenüber einem bloßen Biegeteil wesentlich formsteifer, auch wenn verhältnismäßig dünnes Blechmaterial verwendet wird.In contrast to the known hanger, which is a mere bent part, the hanger according to the invention adjusts Shaped part, in the shaping of which the sheet metal material flows in the manner of a deep-drawing process. Such a sheet metal part is substantially more rigid than a bend part, even if relatively thin sheet material is used.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Abhängerunterteil ein in der Ebene der Stegfläche des Abhängeroberteils liegendes Flächenstück aufweist, von dessen beiden Seitenrändern jeweils senkrecht dazu ein Steg abgewinkelt ist, und daß vom Ende des Stegs jeweils eine seitliche Traglasche abgewinkelt ist, die parallel und im Abstand zur Ebene des Flächenstücks liegt.According to a particularly preferred embodiment of the invention, it is provided that the lower hanger part has a surface piece lying in the plane of the web surface of the upper hanger part, from the two side edges of which a web is angled perpendicularly thereto, and that a lateral carrying strap is angled from the end of the web. which is parallel and at a distance from the plane of the patch.

Im Gegensatz zu dem gattungsbildenden Stand der Technik wird hierbei der Steg, der den Abstand zwischen den seitlichen Traglaschen einerseits und der Ebene der Stegfläche des Abhängers überbrückt, aus demjenigen Bereich des Zuschnitts gewonnen, der sich nach den beiden Seiten hin erstreckt, so daß der Zuschnitt nur so lang gewählt werden muß wie der fertige Abhänger. Dadurch wird eine besondere günstige Materialausnutzung erreicht.In contrast to the generic state of the art, the web, which bridges the distance between the lateral support straps on the one hand and the level of the web surface of the suspension, is obtained from that area of the blank that extends to the two sides, so that the blank only have to be chosen as long as the finished hanger. This results in a particularly favorable use of materials.

Vorzugsweise ist das Abhängerunterteil mit einem senkrechten Flächenstück versehen, an dessen beiden Seitenrändern ein unter den Randstreifen greifender Tragabschnitt ausgebildet ist, in dem eine senkrechte Sicke verläuft. Dadurch wird erreicht, daß dieser Tragabschnitt vor allem in senkrechter Richtung eine hohe Tragfestigkeit erhält. Außerdem ist die Fläche, mit der der durch die Sicke gekrümmte Tragabschnitt den Randstreifen der aufgenommenen C-Profilschiene untergreift, verhältnismäßig groß, so daß auch bei einer hohen Belastung die Gefahr eines Durchschneidens vermieden wird.The lower part of the hanger is preferably provided with a vertical surface piece, on the two side edges of which a support section is formed which extends under the edge strips and in which a vertical bead runs. This ensures that this support section receives a high load-bearing capacity, especially in the vertical direction. In addition, the area with which the support section curved by the bead is the edge strip of the accommodated C profile rail engages, relatively large, so that the risk of cutting through is avoided even at high loads.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, daß die beiden senkrechten Sicken der beiden Tragabschnitte durch eine waagerechte Sicke mit einer mittleren senkrechten Sicke verbunden sind. Dadurch wird insgesamt eine wesentliche Erhöhung der Tragfähigkeit auch bei Verwendung von verhältnismäßig dünnem Blech erreicht.According to a preferred embodiment, it is provided that the two vertical beads of the two support sections are connected by a horizontal bead to a central vertical bead. As a result, a substantial increase in the load-bearing capacity is achieved even when using relatively thin sheet metal.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawing. It shows:
  • 1 is a hanger for C-profile rails of a suspended ceiling in a view in the longitudinal direction of the C-profile rail,
  • 2 is a view in the direction of arrow II in Fig. 1,

Der in der Zeichnung dargestellte Abhänger dient dazu, eine C-Profilschiene 1, die in der Zeichnung jeweils mit strichpunktierten Linien nur angedeutet ist, von einer Rohbaudecke abzuhängen. Die C-Profilschiene 1 ist eine Tragschiene eines Traggerippes einer abhängten Unterdecke.The hanger shown in the drawing is used to hang a C-shaped rail 1, which is only indicated in the drawing with dash-dotted lines, from a structural ceiling. The C-profile rail 1 is a mounting rail of a supporting frame of a suspended false ceiling.

Die C-Profilschiene 1 weist eine untenliegende flache Stegfläche 2 auf, von der zwei Flanschflächen 3 senkrecht nach oben abgewinkelt sind. Von den Oberkanten der beiden beiden Flanschflächen 3 erstreckt sich jeweils ein im Querschnitt beispielsweise halbkreisförmiger Randstreifen 4 nach innen. Die C-Profilschiene 1 wird von mehreren, über ihre Länge verteilten Abhängern 5 getragen, die jeweils über ein (nicht dargestelltes) Abhängerteil an der Rohbaudecke höhenverstellbar angebracht sind.The C-profile rail 1 has a flat web surface 2 lying below, from which two flange surfaces 3 are angled vertically upwards. From the upper edges of the two flange surfaces 3, an edge strip 4, for example semicircular in cross section, extends inwards. The C-profile rail 1 is supported by a plurality of hangers 5 distributed over its length, each of which is attached to the structural ceiling by means of a hanging part (not shown).

Der Abhänger 5 weist ein nach oben ragendes, im horizontalen Querschnitt U-förmiges Abhängeroberteil 6 auf, das nach unten in ein Abhängerunterteil 7 übergeht, das der Verbindung mit der C-Profilschiene 1 dient.The hanger 5 has an upwardly projecting, upper cross-sectionally U-shaped upper hanger part 6, which merges downwards into a lower hanger part 7, which is used for connection to the C-profile rail 1.

Das Abhängerunterteil 7 weist ein Querstück auf, das aus zwei in einer horizontalen Ebene liegenden Querstückabschnitten 8 besteht. Diese Querstückabschnitte 8 liegen an der Oberseite der Randstreifen 4 der C-Profilschiene 1 an und stützen diese nach oben ab.The lower hanger part 7 has a cross piece, which consists of two cross piece sections 8 lying in a horizontal plane. These cross-piece sections 8 rest on the top of the edge strips 4 of the C-profile rail 1 and support them upwards.

Jeweils die äußeren Enden der Querstückabschnitte 8 sind als Endlaschen 9 nach unten abgewinkelt, die an der Außenseite der oberen Ränder der C-Profilschiene 1 flach anliegen.In each case, the outer ends of the crosspiece sections 8 are angled downward as end plates 9, which lie flat on the outside of the upper edges of the C-profile rail 1.

Das U-förmige Abhängeroberteil 6 weist eine Stegfläche 10 auf, die nach unten in ein in der gleichen senkrechten Ebene liegendes Flächenstück 11 des Abhängerunterteils 7 übergeht. Dieses Flächenstück 11 ist in der Mitte durch eine senkrechte Sicke 12 versteift. Das Flächenstück 11 weist eine nach unten ragende Verlängerung auf, die den Boden 2 der C-Profilschiene 1 gegen ein unbeabsichtigtes Anheben sichert.The U-shaped upper hanger part 6 has a web surface 10 which merges downward into a surface piece 11 of the lower hanger part 7 lying in the same vertical plane. This area piece 11 is stiffened in the middle by a vertical bead 12. The surface piece 11 has a downwardly projecting extension, which secures the bottom 2 of the C profile rail 1 against unintentional lifting.

An den beiden Seitenrändern des Flächenstücks 11 ist jeweils ein Tragabschnitt 13 ausgebildet, in dem eine senkrechte Sicke 14 verläuft. Dadurch erhält der Tragabschnitt 13 in der Draufsicht (Fig. 3) im wesentlichen die Querschnittsgestalt eines Halbzylinders, dessen äußerer, senkrechter Wandabschnitt 13a innen parallel zur Flanschfläche 3 der C-Profilschiene 1 verläuft.A support section 13 is formed on each of the two side edges of the surface piece 11, in which a vertical bead 14 extends. As a result, the top view of the support section 13 (FIG. 3) essentially has the cross-sectional shape of a half cylinder, the outer, vertical wall section 13a of which runs on the inside parallel to the flange surface 3 of the C profile rail 1.

Fig. 5 läßt erkennen, daß der Tragabschnitt 13 und insbesondere der Wandabschnitt 13a nach oben vorspringen und eine unter den Randstreifen 4 greifende Haltenase 13b bilden, die so gestaltet ist, daß außer einem halbkreisförmig gekrümmten Randstreifen 4 auch ein schärfer abgewinkelter Randstreifen aufgenommen werden kann, wie in Fig. 5 angedeutet.5 shows that the support section 13 and in particular the wall section 13a protrude upwards and form a retaining lug 13b which engages under the edge strips 4 and which is designed such that, in addition to a semicircularly curved edge strip 4, a sharply angled edge strip can also be accommodated, as indicated in Fig. 5.

Der in Längsrichtung der C-Profilschiene 1 gemessene lichte Abstand a (Fig. 3) zwischen dem Tragabschnitt 13 und dem ihm zugewandten Rand des Querstückabschnitts 8 ist aus Gründen der Montage, wie später noch erläutert wird, mindestens so groß wie die Höhe h des gewölbten Randstreifens 4 der C-Profilschiene 1 (Fig. 4).The clear distance a (FIG. 3) measured in the longitudinal direction of the C-shaped rail 1 between the support section 13 and the edge of the cross-section section 8 facing it is, for reasons of assembly, as will be explained later, at least as large as the height h of the curved one Edge strip 4 of the C-profile rail 1 (Fig. 4).

Eine waagerechte Sicke 12a verbindet die mittlere Sicke 12 mit den beiden senkrechten Sicken 14 am Rand, so daß ein zusammenhängendes System von Versteifungssicken gebildet wird.A horizontal bead 12a connects the middle bead 12 to the two vertical beads 14 at the edge, so that a coherent system of stiffening beads is formed.

Wie man aus Fig. 1 erkennt, gehen seitliche Flansche 15 des Abhängeroberteils 6 jeweils in einem Bogen 16 in die beiden seitlichen Querstückabschnitte 8 über. Der Abhänger 5 bildet in diesem Übergangsbereich ein in sich formsteifes Formteil. Man erkennt aus Fig. 1 besonders deutlich, daß die seitlichen Querstückabschnitte 8 und deren Endlaschen 9 nahe an der C-Profilschiene anliegen und daher nur sehr wenig über deren Außenkontur vorragen. Wenn neben und über der C-Profilschiene 1 Isoliermaterial, insbesondere für den Brand- und Schallschutz eingebracht wird, stört das Abhängerunterteil 7 deshalb nicht.As can be seen from FIG. 1, lateral flanges 15 of the upper hanger part 6 each pass in an arc 16 into the two lateral cross-section sections 8. The hanger 5 forms in itself in this transition area dimensionally stable molded part. It can be seen particularly clearly from FIG. 1 that the lateral cross-piece sections 8 and their end plates 9 lie close to the C-profile rail and therefore protrude very little beyond their outer contour. If, next to and above the C-profile rail 1, insulating material is introduced, especially for fire and sound insulation, the lower hanger part 7 does not interfere.

Die Montage erfolgt in der in Fig. 4 angedeuteten Weise. Der Abhänger 5 wird so auf die C-Profilschiene 1 gelegt, daß er schräg zur Längsrichtung der C-Profilschiene 1 verläuft. In dieser Stellung können die Tragabschnitte 13 zwischen die Randstreifen 4 eingeführt werden. Anschließend wird der Abhänger 5 angenähert in Längsrichtung der C-Profilschiene 1 ausgerichtet und aus dieser Stellung in Richtung des Pfeiles 17 bis in die senkrechte Stellung gemäß Fig. 2 hochgeklappt. In dieser senkrechten Stellung, die durch die Verbindung zur Rohbaudecke gesichert ist, ist der Abhänger 5 formschlüssig mit der C-Profilschiene 1 verbunden und kann weder durch ein Anheben der C-Profilschiene 1 noch durch eine Drehung des Abhängers 5 gelöst werden. Die seitlich an den Flanschflächen 3 der C-Profilschiene 1 anliegenden Endlaschen 9 verhindern ein seitliches Aufbiegen der C-Profilschiene 1 insbesondere im Brandfall. Damit wird zugleich verhindert, daß sich die C-Profilschiene 1 im Brandfall vom Abhänger 5 lösen könnte.The assembly is carried out in the manner indicated in FIG. 4. The hanger 5 is placed on the C-profile rail 1 so that it runs obliquely to the longitudinal direction of the C-profile rail 1. In this position, the support sections 13 can be inserted between the edge strips 4. Then the hanger 5 is aligned approximately in the longitudinal direction of the C-profile rail 1 and folded up from this position in the direction of the arrow 17 into the vertical position according to FIG. 2. In this vertical position, which is secured by the connection to the structural ceiling, the hanger 5 is positively connected to the C-profile rail 1 and can neither be released by lifting the C-profile rail 1 nor by rotating the hanger 5. The end flaps 9 lying laterally on the flange surfaces 3 of the C-profile rail 1 prevent the C-profile rail 1 from bending open laterally, in particular in the event of a fire. This also prevents the C-profile rail 1 from detaching from the hanger 5 in the event of a fire.
