Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Abhängen C-förmiger Tragschienen, mit einem bei be­stimmungsgemäßer Verwendung in Querstellung zur Längs­richtung einer Tragschiene zwischen deren sich in Parallellage vom Tragschienen-Profilsteg forterstrek­kende Profilschenkel einsetzbaren Ankerkopf, der zwei seitliche Halteabschnitte besitzt, die in der Montage­lage die an den von dem genannten Profilsteg entfernten Längskanten der Profilschenkel längsverlaufend einwärts abgekanteten Randflanschen der Tragschiene hinter­greifen, und mit einem sich auf einer Seite (der Offen­seite der Tragschienen) vom Ankerkopf forterstrecken­den Ankersteg. Insbesondere bezieht sich die Erfindung auf einen Ankerhänger, Winkelanker oder dergleichen.The invention relates to a device for hanging C-shaped mounting rails, with an intended use in the transverse position to the longitudinal direction of a mounting rail between which in parallel position of the mounting rail profile web forward extending profile arm anchor head, which has two lateral holding sections, which in the mounting position reach behind the edge flanges of the mounting rail, which are bent inwards and longitudinally, from the longitudinal edges of the profile legs that are distant from the said profile web, and with an anchor web extending on one side (the open side of the mounting rails) from the anchor head. In particular, the invention relates to an anchor hanger, angle anchor or the like.

Vorrichtungen dieser Art sind bekannt. Sogenannte Ankerhänger werden beim Aufbau von Unterkonstruktionen für abgehängte Unterdecken zum Abhängen von Decken­ tragschienen verwendet, sogenannte Winkelanker hin­gegen. zum Verbinden einander im wesentlichen recht­winklig kreuzender Tragschienen.Devices of this type are known. So-called anchor hangers are used in the construction of substructures for suspended ceilings for hanging ceilings DIN rails used, so-called angle anchors, however. for connecting support rails which cross one another essentially at right angles.

Bei den Tragschienen handelt es sich um leichte Blech­profile mit einem in der Montagelage nach unten wei­senden Profilsteg und sich von diesem im Abstand von­einander erstreckenden, nach oben gerichteten Profil­schenkeln, längs deren Oberkanten nach einwärts gerich­tete Flanschen abgekantet sind.The mounting rails are lightweight sheet metal profiles with a profile web pointing downwards in the assembly position and extending upwards from this at a distance from each other, upwardly directed profile legs, along the upper edges of which inwardly directed flanges are folded.

Bei den Ankerhängern handelt es sich in der Regel um aus Blechen ausgeschnittene flache Stanzteile, die in einer Stellung ihres Ankerkopfs quer zur Längserstrek­kung der C-förmigen Tragschienen mit ihren seitlichen Halteabschnitten derart in die Tragschienen eingreifen, daß eine formschlüssige Verbindung zwischen den seit­lichen Halteabschnitten und den nach einwärts gerich­teten Flanschen der Tragschienen zustandekommt. Die Breite des Ankerstegs mit den Halteabschnitten ist dabei annähernd gleich dem Innenmaß zwischen den Profil­schenkeln der Tragschienen und die dazu rechtwinklig verlaufende Erstreckung ist so bemessen, daß die Halte­abschnitte die erwähnten Halteflanschen der Tragschie­nen hintergreifen, während die vom Ankersteg entfernte Seite des Ankerkopfs sich auf dem Profilsteg der Trag­schiene abstützt.The anchor hangers are usually flat stamped parts cut from sheet metal, which in one position of their anchor head transversely to the longitudinal extension of the C-shaped support rails engage with their lateral holding sections in the support rails such that a positive connection between the lateral holding sections and the after inward flanges of the mounting rails. The width of the anchor bar with the holding sections is approximately equal to the internal dimension between the profile legs of the mounting rails and the extension extending at right angles thereto is such that the holding sections engage behind the holding flanges of the mounting rails mentioned, while the side of the anchor head remote from the anchor bar is on the profile bar supports the mounting rail.

Beim Aufbau einer Unterkonstruktion werden an den für letztere bestimmten Tragschienen die Ankerhänger in vorbestimmten Abständen voneinander montiert und dann beispielsweise an Abhängemittel angehängt, die an der mit einer derartigen Unterkonstruktion zu ver­sehenden Baukörperdecke vormontiert sind. Häufig han­delt es sich dabei um an der Bauwerksdecke lagerichtig angebrachte Hängedrähte, die dann in an den Anker­stegen der Ankerhänger befestigte Klemmhalterungen eingeführt werden. Dadurch kommt in hier im einzelnen nicht interessierender Weise eine zugfeste Verbindung zwischen den Klemmhalterungen und den genannten Hänge­drähten zustande.When building a substructure, the anchor hangers are mounted at predetermined distances from one another on the support rails intended for the latter and then for example attached to suspension means, which are pre-assembled on the structural ceiling to be provided with such a substructure. Often, these are hanging wires that are correctly positioned on the ceiling of the building and are then inserted into clamping brackets attached to the anchor bars of the anchor hangers. As a result, a tensile connection between the clamping brackets and the suspension wires mentioned is achieved in a manner of no particular interest here.

Auch bei den Winkelankern handelt es sich in aller Regel um aus Blechen ausgeschnittene flache Stanzteile mit einem zwei seitliche Halteabschnitte aufweisenden Ankerkopf, der in der Montagelage in gleicher Weise wie der Ankerkopf eines Ankerhängers von der Offen­seite aus in eine Tragschiene eingesetzt ist und mit den seitlichen Halteabschnitten die einwärts abgekanteten Randflanschen an den freien Längskanten der Tragschie­nenschenkel hintergreift.The angled anchors are generally flat stamped parts cut out of sheet metal with an anchor head that has two lateral holding sections, which is installed in the mounting position in the same way as the anchor head of an anchor hanger from the open side into a mounting rail and with the lateral holding sections engages behind the inwardly folded edge flanges on the free longitudinal edges of the mounting rail legs.

Winkelanker dienen beispielsweise der unterseitigen Anbringung von C-förmigen Deckenprofilen an im Abstand voneinander in einer Ebene in Parallellage verlaufenden Tragschienen mit C- oder U-förmigem Querschnitt, die ihrerseits beispielsweise mittels der oben erwähnten Ankerhänger an einer Rohbaudecke abgehängt sind. Der­artige Winkelanker finden aber auch beim Aufbau doppel­schaliger Unterdecken Verwendung, etwa bei Unterdecken mit einer oberseitigen und auf einer an einer Rohbau­decke abgehängten Unterkonstruktion aufgenommenen Feuerschutzabdeckung und einer unterseitigen Sicht­decke, deren Platten oder Paneele an einer unter der die Feuerschutzabdeckung tragenden Unterkonstruktion abgehängten Unterkonstruktion befestigt sind, die ihrerseits aus unter Verwendung von Winkelankern an der die Feuerschutzabdeckung tragenden Unterkonstruktion angebrachten C-förmigen Tragschienen besteht.Angle anchors are used, for example, to attach C-shaped ceiling profiles on the underside to support rails with a C or U-shaped cross-section which are spaced apart from one another in a plane and are in turn suspended from a structural ceiling, for example by means of the anchor hangers mentioned above. Such angle anchors are also used in the construction of double-skin suspended ceilings, for example in suspended ceilings with a top structure and a substructure suspended from a structural ceiling Fire protection cover and an underside visible ceiling, the plates or panels of which are attached to a substructure suspended under the substructure carrying the fire protection cover, which in turn consists of C-shaped support rails attached to the substructure carrying the fire protection cover using angle anchors.

Während bei den Ankerhängern der sich in der Montage­lage auf der Offenseite der Tragschienen vom Ankerkopf forterstreckende Mittelsteg mit Mitteln zum Befestigen an einer Rohbaudecke, wie Klemmhalterungen für die Aufnahme eines vormontierten Hängedrahtes, ausgerüstet ist, sind bei den Winkelankern die jeweils vom Ankerkopf entfernten Enden der Ankerstege als abbiegbare Halte­laschen ausgebildet. Bei bestimmungsgemäßer Verwen­dung werden die Winkelanker in gleicher Weise wie die Ankerhänger so an unter einer bereits abgehängten Unterkonstruktion anzubringenden Tragschienen mon­tiert, daß die Ankerstege in Querstellung zur Längs­erstreckung der Tragschienen sich auf deren Offen­seite forterstrecken. Die so mit vormontierten Winkel­ankern ausgerüsteten Tragschienen werden dann unter­seitig an bereits montierten U- oder C-förmigen Trag­schienen angelegt, daß die hochstehenden Ankerstege sich seitlich jeweils an einem hochstehenden Profilsteg einer Tragschiene der bereits montierten Unterkonstruktion entlang erstrecken. Die formschlüssig feste Verbindung einer unteren Tragschiene mit einer sich rechtwinklig zu dieser erstreckenden oberen Tragschiene erfolgt dann in der Weise, daß die hochstehenden Enden der Ankerstege um die Oberkante der hochstehenden Profilstege eines oberen Tragprofils herumgebogen werden, wodurch die unteren Tragschienen mit den oberen Tragschienen mehr oder weniger verspannt und an letzteren klapperfrei festgelegt werden.While in the case of the anchor hangers, the center bar, which extends from the anchor head on the open side of the mounting rails, is equipped with means for fastening to an unfinished ceiling, such as clamp brackets for receiving a preassembled hanging wire, the ends of the anchor bars are removed from the anchor head for the angle anchors formed as a bendable holding tabs. When used as intended, the angle anchors are mounted in the same way as the anchor hangers on support rails to be attached under an already suspended substructure in such a way that the anchor bars extend in the transverse position to the longitudinal extension of the support rails on their open side. The support rails equipped with pre-assembled angle anchors are then placed on the underside of already installed U- or C-shaped support rails, so that the upstanding anchor webs extend laterally along a raised profile web of a support rail along the already assembled substructure. The form-fitting, firm connection of a lower mounting rail with an upper mounting rail extending at right angles to this then takes place in such a way that the upstanding ends of the Anchor webs are bent around the upper edge of the upstanding profile webs of an upper support profile, whereby the lower support rails are more or less braced with the upper support rails and fixed to the latter without rattling.

Sowohl bei den Tragschienen als auch bei den Anker­hängern und Winkelankern handelt es sich um Massen­teile, bei denen unvermeidbar auftretende Maßabwei­chungen dazu führen können, daß vormontierte Anker­hänger nicht lagesicher in den Tragschienen gehalten sind. Demgemäß gestaltet sich das Anhängen der mit vormontierten Ankerhängern ausgerüsteten Tragschienen an die an einer Bauwerksdecke vormontierten Abhänge­mittel häufig als schwierig und zeitaufwendig. Sinn­gemäß gleiches gilt beim Verbinden einander kreuzender Tragschienen, weil die vormontierten Winkelanker leicht aus ihrer Montagelage abkippen, bevor die oberen Enden der als Haltelasche ausgebildeten Ankerstege in eine die hochstehenden Schenkel der jeweils oberen Trag­schiene übergreifende Haltelage abgebogen werden können.Both the mounting rails as well as the anchor hangers and angle anchors are mass parts in which inevitable dimensional deviations can lead to pre-assembled anchor hangers not being held securely in the mounting rails. Accordingly, the attachment of the mounting rails equipped with preassembled anchor hangers to the suspension means preassembled on a building ceiling is often difficult and time-consuming. The same applies mutatis mutandis when connecting support rails that cross each other, because the pre-assembled angle anchors easily tip out of their mounting position before the upper ends of the anchor webs designed as holding tabs can be bent into a holding position that overlaps the upstanding legs of the respective upper mounting rail.

Eine weitere Unzulänglichkeit der vorbekannten Anker­hänger und Winkelanker besteht darin, daß beim Auf­treten größerer Lasten sowohl Deformationen an den seitlichen Halteabschnitten der Ankerköpfe als auch an den von den Halteabschnitten hintergriffenen Rand­flanschen der Tragschienen auftreten können. Insbe­sondere bei doppelschaligen Unterdecken besteht die Gefahr derartiger Deformationen an den die obere Unter­konstruktion bildenden Tragschienen und den zugeordneten Ankerhängern.Another inadequacy of the known anchor hangers and angle anchors is that when larger loads occur, deformations can occur both on the lateral holding sections of the anchor heads and on the edge flanges of the mounting rails which are gripped by the holding sections. In the case of double-shell suspended ceilings in particular, there is a risk of such deformations on the support rails forming the upper substructure and the associated anchor hangers.

Demgemäß soll durch die Erfindung eine verbesserte, insbesondere einfach montierbare Vorrichtung zum Ab­hängen C-förmiger Tragschienen geschaffen werden, die einerseits im vormontierten Zustand lagesicher in der jeweiligen Tragschiene aufgenommen ist und anderer­seits auch die Aufnahme größerer Lasten ohne die Gefahr von Deformationen im Bereich der seitlichen Halteab­schnitte und der von diesen in der Montagelage hinter­griffenen Randflanschen der Tragschienen ermöglicht.Accordingly, the invention is intended to provide an improved, in particular easy-to-assemble, device for suspending C-shaped mounting rails, which on the one hand is securely received in the respective mounting rail in the preassembled state and on the other hand also accepts larger loads without the risk of deformation in the region of the lateral holding sections and the edge flanges of the mounting rails gripped by these in the mounting position.

Gelöst ist diese Aufgabe dadurch, daß bei der Vorrich­tung nach dem Oberbegriff des Patentanspruchs 1 die seitlichen Halteabschnitte aus der vom Mittelteil des Ankerkopfs aufgespannten Ebene herausgeformt sind und in der Montagelage die Randflanschen einer Tragschiene jeweils an wenigstens zwei in Tragschienenlängsrichtung beabstandeten Angriffspunkten hintergreifen.This object is achieved in that, in the device according to the preamble of claim 1, the lateral holding sections are formed out of the plane spanned by the central part of the anchor head and in the mounting position the edge flanges of a mounting rail each engage behind at least two points of attack spaced apart in the longitudinal direction of the mounting rail.

Während bei bekannten Vorrichtungen die Breite der Halte­abschnitte gleich der gewählten Blechstärke war, besitzen die Halteabschnitte der erfindungsgemäßen Vorrichtung je­weils zwei Angriffsbereiche, mit denen sie die Tragschienen­Randflanschen hintergreifen. Sie haben daher eine wesentlich verbesserte Tragfähigkeit und im vormontierten Zustand ist die Gefahr des Kippens um eine quer zur Tragschienenlängs­richtung verlaufende Achse praktisch ausgeschaltet, weil jeder Halteabschnitt in wenigstens zwei in Tragschienen­längsrichtung im Abstand voneinander liegenden Punkten an den Randflanschen angreift. Insbesondere ist dies der Fall, wenn gemäß einer Weiterbildung die seitlichen Halteabschnitte mit - in der Montagelage - in Tragschienenlängsrichtung ver­ laufenden Halteflächen versehen sind und über ihre gesamte Längenerstreckung die von den Profilstegen einwärts abgekanteten Randflanschen hintergreifen.While in known devices the width of the holding sections was equal to the selected sheet thickness, the holding sections of the device according to the invention each have two engagement areas with which they engage behind the mounting rail edge flanges. They therefore have a significantly improved load-bearing capacity and, in the preassembled state, the risk of tipping over an axis running transversely to the longitudinal direction of the mounting rail is practically eliminated because each holding section acts on the edge flanges in at least two points spaced apart in the longitudinal direction of the mounting rail. In particular, this is the case if, according to a further development, the lateral holding sections ver - in the mounting position - in the longitudinal direction of the mounting rail running holding surfaces are provided and over their entire length extend behind the edge flanges bent inwards from the profile webs.

Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß die seitlichen Halteabschnitte aus der Ebene des Ankerkopf-Mittelteils nach der gleichen Seite etwa halbkreisbogenförmig herausgeformt sind. Dabei können die in der Montagelage die Tragschienen-­Randflanschen hintergreifenden Bereiche der Halteab­schnitte nach der zum Ankersteg hinweisenden Seite mit Vorteil derart gekrümmt ausgebildet sein, daß die hinter die Randflanschen greifenden Bereiche auf praktisch ihrer gesamten in Tragschienenlängsrichtung weisenden Länge an den Randflanschen angreifen.Another advantageous development of the invention provides that the lateral holding sections are shaped approximately semicircularly out of the plane of the anchor head middle part on the same side. In this case, the areas of the holding sections that engage behind the mounting rail edge flanges in the mounting position can advantageously be curved on the side pointing toward the anchor web in such a way that the areas reaching behind the edge flanges engage the edge flanges over practically their entire length pointing in the longitudinal direction of the mounting rail.

Eine andere vorteilhafte Weiterbildung sieht vor, daß die Erstreckung der Halteabschnitte in Richtung des Ankerstegs größer ist als die Höhe der Profilschenkel der abzuhängenden Tragschienen und daß die Halteab­schnitte mit seitlichen Ausklinkungen versehen sind, deren vom Ankersteg entfernte Begrenzungen die Trag­schienen-Randflanschen in der Montagelage hintergreifen. Wenn die Erstreckung der Ausklinkungen in den seitlichen Halteabschnitten entsprechend der Erstreckung der Trag­schienen-Randflanschen in Richtung der Höhe der Profil­schenkel bemessen ist, vermitteln die in der Montage­lage in die Ausklinkungen hineinragenden und von den unteren Begrenzungen der Ausklinkungen hintergriffenen Randflanschen eine weitere Sicherung gegen unerwünsch­tes Kippen im Vormontagezustand.Another advantageous further development provides that the extension of the holding sections in the direction of the anchor web is greater than the height of the profile legs of the mounting rails to be suspended and that the holding sections are provided with lateral notches, the limits of which are removed from the anchor web and engage behind the mounting rail edge flanges in the installed position. If the extent of the notches in the lateral holding sections is dimensioned in accordance with the extent of the mounting rail edge flanges in the direction of the height of the profile legs, the edge flanges which protrude into the notches in the mounting position and are gripped by the lower boundaries of the notches provide further protection against undesired tipping in the Pre-assembled condition.

Gleichfalls im Sinne einer verbesserten Festlegung im Vormontagezustand dient eine Ausgestaltung der erfindungsgemäßen Vorrichtung dergestalt, daß der Ankerkopf und/oder die Halteabschnitte auf der vom Ankersteg entfernten Seite mit Füßchen versehen sind, die in der Montagelage auf dem Tragschienen-Profil­steg aufstehen, so daß der Ankerkopf mit den Halte­abschnitten zwischen dem Profilsteg der jeweiligen Tragschiene und deren einwärts abgekanteten Randflan­schen verspannt ist.Likewise in the sense of an improved definition in the pre-assembly state, an embodiment of the device according to the invention is used such that the anchor head and / or the holding sections on the side remote from the anchor web are provided with feet which stand up on the mounting rail profile web in the assembly position, so that the anchor head is braced with the holding sections between the profile web of the respective mounting rail and its inwardly bent edge flanges.

Bei der Ausbildung der Vorrichtung als Winkelanker sieht eine weitere erfindungsgemäße Ausgestaltung vor, daß der vom Ankerkopf entfernte Endabschnitt des Ankerstegs als abbiegbare Haltelasche ausgebildet und in einem der Höhe der Tragschienen-Profilschenkel entsprechenden Abstand von den seitlichen Halteabschnitten mit einer quer zur Ankerstegerstreckung nach der Seite der Halteabschnitte herausgeformten Federzunge versehen ist, die beim Anhängen einer mit vormontierten Winkel­ankern ausgerüsteten Tragschiene an eine Tragschiene einer bereits abgehängten Unterkonstruktion in ein­facher Weise auf die Oberkante der zu der bereits abgehängten Unterkonstruktion gehörenden Tragschiene aufgeclipt werden kann, bevor die abbiegbare Halte­lasche um die Oberkante der erwähnten oberen Trag­schiene herumgebogen wird.When designing the device as an angle anchor, a further embodiment according to the invention provides that the end section of the anchor web, which is removed from the anchor head, is designed as a bendable holding tab and at a distance corresponding to the height of the mounting rail profile leg from the lateral holding sections with a transverse to the anchor web extension on the side of Holding sections molded spring tongue is provided, which can be easily clipped onto the upper edge of the support rail belonging to the already suspended substructure when attaching a support rail equipped with preassembled angle anchors to a support rail of a previously suspended substructure, before the bendable retaining tab around the upper edge of the above-mentioned upper Carrier rail is bent around.

Bei der in den Fig. 1 bis 4 strichpunktiert angedeuteten Tragschiene 10 handelt es sich um ein C-förmiges Blech­profil mit einem in der Montagelage untenliegenden Profil­steg 11 und sich im Abstand voneinander vom Profilsteg nach oben erstreckenden Profilschenkeln 12, von deren jeweils vom Profilsteg 11 entfernten Längskanten 13 Randflanschen 14 nach innen abgekantet sind.1 to 4 indicated by dash-dotted lines, it is a C-shaped sheet metal profile with a profile web 11 lying in the mounting position and extending at a distance from the profile web upward profile legs 12, each of which removed from the profile web 11 Longitudinal edges 13 edge flanges 14 are folded inwards.

In Fig. 2 sind längs der Tragschiene im Abstand von­einander zwei Ankerhänger 18 angeordnet, die in unten noch zu beschreibender Weise formschlüssig zwischen die in der Montagelage hochstehenden Profilschenkel 12 der Tragschiene 10 eingreifen und ihrerseits mittels mit an einer nichtgezeigten Baukörperdecke befestigten Hängedrähten 15 zusammenwirkender Klemmfedern 16 an den genannten Hängedrähten abgehängt sind.In FIG. 2, two anchor hangers 18 are arranged along the support rail at a distance from one another, which engage in a form-fitting manner between the upright profile legs 12 of the support rail 10 in the manner to be described below and in turn by means of clamping springs 16 which cooperate with hanging wires 15 fastened to a structural ceiling (not shown) are suspended from the suspension wires mentioned.

Bei dem Ankerhänger 18 handelt es sich um ein Blechform­teil mit einem symmetrisch zu einer Mittelachse 19 ausge­bildeten Ankerkopf 20, der zwei seitliche Halteabschnitte 21 besitzt, und mit einem sich auf einer Seite vom Anker­kopf forterstreckenden und mit diesem einstückig ausgebil­deten Ankersteg 22. Die seitlichen Halteabschnitte 21 des Ankerkopfs 20 sind ebenfalls einstückig mit diesem aus­gebildet und aus der vom Ankersteg 22 und dem Mittel­teil des Ankerkopfs aufgespannten Ebene jeweils nach einer Seite halbkreisförmig abgebogen. In beiden Halteabschnitten 21 befinden sich, wie insbesondere Fig. 6 anhand einer Abwicklung zeigt, in der Nähe ihrer zum Ankersteg 22 hinweisenden Enden Ausklinkungen 24, deren Erstreckung in Richtung des Ankerstegs 22 so bemessen ist, daß sie zwanglos die einwärts gerichteten Randflanschen 14 an den vom Profilsteg 11 entfernten Enden der Profilschen­kel 12 der Tragschienen zu übergreifen vermögen. Auf der vom Ankersteg 22 entfernten Seite sind die Begrenzun­gen 25 der Ausklinkungen 24 in den Halteabschnitten 21 bogenförmig ausgebildet und in der Mitte des Ankerkopfs 20 und an den Enden der kreisbogenförmig ausgebildeten Halteabschnitte 21 sind unterseitig Füßchen 26, 27 ange­formt. Das Außenmaß der kreisbogenförmigen Halteab­schnitte 21 ist etwas kleiner als das Innenmaß zwischen den Profilschenkeln 12 der mittels des Ankerhängers abzu­hängenden Tragschienen 10 und die Erstreckung zwischen den unterseitigen Füßchen 26, 27 des Ankerkopfs 20 und der Halteabschnitte 21 und den vom Ankersteg entfernten bogen­förmigen Begrenzungen 25 der Ausklinkungen 24 ist annähernd gleich dem Abstandsmaß zwischen dem Profilsteg 11 und den von den Profilschenkeln 12 einwärts abgekanteten Randflanschen 14. Im übrigen sind im Ankersteg hier nicht weiter interessierende Verstärkungssicken und Lochungen zum Befestigen beispielsweise der Klemmfeder 16 - oder anderer geeigneter Anhängemittel - vorgesehen.The anchor hanger 18 is a molded sheet metal part with an anchor head 20 formed symmetrically to a central axis 19, which has two lateral holding sections 21, and with an anchor web 22 which extends on one side from the anchor head and is integrally formed therewith. The lateral holding sections 21 of the anchor head 20 are also formed integrally therewith and are bent semicircularly to one side in each case from the plane spanned by the anchor web 22 and the central part of the anchor head. In both holding sections 21 there are, as shown in particular in FIG Development shows, in the vicinity of their ends pointing toward the anchor web 22 notches 24, the extent of which in the direction of the anchor web 22 is dimensioned such that they are able to encompass the inward-facing edge flanges 14 at the ends of the profile leg 12 of the mounting rails remote from the profile web 11. On the side distant from the anchor web 22, the boundaries 25 of the notches 24 in the holding sections 21 are arcuate and in the middle of the anchor head 20 and at the ends of the circular arc-shaped holding sections 21 feet 26, 27 are formed on the underside. The outer dimension of the circular arc-shaped holding sections 21 is somewhat smaller than the inner dimension between the profile legs 12 of the support rails 10 to be suspended by means of the anchor hanger and the extent between the feet 26, 27 of the anchor head 20 and the holding sections 21 on the underside and the arcuate boundaries 25 of the notches removed from the anchor web 24 is approximately the same as the distance between the profile web 11 and the edge flanges 14 bent inwards from the profile legs 12. In addition, reinforcing beads and perforations for attaching, for example, the clamping spring 16 - or other suitable attachments - are not provided here in the anchor web.

Die Fig. 3 und 4 zeigen in Verbindung mit einer strich­punktiert angedeuteten Tragschiene 10 die Montagelage des Ankerhängers 18, in der die vom Ankersteg 22 und vom Mittelteil des Ankerkopfs 20 aufgespannte Ebene sich quer zur Längsrichtung der Tragschiene erstreckt. Die unterseitigen Füßchen 26, 27 des Ankerkopfs 20 und der daran halbkreisbogenförmig angeformten Halteab­schnitte 21 stehen auf dem Profilsteg 11 der Trag­schiene 10 auf, während die nach einwärts von den Profilschenkel 12 abgekanteten Randflanschen 14 in die seitlichen Ausklinkungen 24 der Halteabschnitte 21 eingreifen und ihrerseits von den kreisbogenför­migen unterseitigen Begrenzungen 25 der Ausklinkungen untergriffen werden. Der Ankerkopf mit den Halteab­schnitten 21 ist somit zwischen dem Profilsteg 11 und den Randflanschen 14 der Tragschiene 10 verspannt und angesichts der in Tragschienenlängsrichtung im Abstand voneinander angeordneten Füßchen 26, 27 an der Unterseite des Ankerkopfs und an den Enden der kreisbogenförmigen Halteabschnitte stehen die Anker­hänger auf dem Profilsteg der Tragschiene auf. Da­durch ist die Gefahr eines Kippens der vormontierten Ankerhänger weitestgehend ausgeschlossen.3 and 4 show in connection with a carrier rail 10 indicated by dash-dotted lines the mounting position of the anchor hanger 18, in which the plane spanned by the anchor web 22 and by the central part of the anchor head 20 extends transversely to the longitudinal direction of the carrier rail. The bottom feet 26, 27 of the anchor head 20 and The holding sections 21 formed thereon in a semicircular arc stand on the profile web 11 of the mounting rail 10, while the edge flanges 14 bent inwards from the profile legs 12 engage in the lateral notches 24 of the holding sections 21 and in turn are undercut by the circular-shaped undersides 25 of the notches. The anchor head with the holding sections 21 is thus clamped between the profile web 11 and the edge flanges 14 of the mounting rail 10 and in view of the feet 26, 27 spaced apart in the longitudinal direction of the mounting rail on the underside of the anchor head and at the ends of the circular-shaped holding sections, the anchor hangers are on the Profile web of the mounting rail. This largely eliminates the risk of the preassembled anchor hanger tipping over.

Die lagerichtige Halterung der Ankerhänger im vor­montierten Zustand wird auch noch dadurch verstärkt, daß die bogenförmig ausgebildeten unteren Begrenzun­gen 25 der Ausklinkungen 24 in den Halteabschnitten 21 die einwärts abgekanteten Tragschienen-Randflan­schen 14 über eine vorbestimmte Erstreckung in Trag­schienenlängsrichtung hintergreifen. Letzteres führt auch zu einer Lastverteilung über einen vorbestimmten Längenabschnitt der Randflanschen der Tragschiene, so daß selbst beim Auftreten größerer Lasten Deformationen der Randflanschen praktisch ausgeschlossen sind. Defor­mationen an den Halteabschnitten selbst können ange­sichts deren halbkreisbogenförmiger Gestaltung und des Eingreifens der Tragschienen-Randflanschen in die erwähnten Ausklinkungen ohnehin nicht auftreten.The correct mounting of the anchor hangers in the preassembled state is also reinforced by the fact that the curved lower boundaries 25 of the notches 24 in the holding sections 21 engage behind the inwardly bent support rail edge flanges 14 over a predetermined extent in the longitudinal direction of the support rail. The latter also leads to a load distribution over a predetermined length section of the edge flanges of the mounting rail, so that deformations of the edge flanges are practically excluded even when larger loads occur. Deformations on the holding sections themselves, given their semicircular shape and shape the engagement of the mounting rail edge flanges in the notches mentioned do not occur anyway.

Die Montage des erfindungsgemäßen Ankerhängers 18 an den Tragschienen 10 gelingt in einfacher Weise, indem der Ankerkopf 20 des Ankerhängers zwischen den nach oben weisenden Profilschenkeln 12 der Tragschienen und den von den freien Längskanten der Profilschenkel nach einwärts gerichteten Randflanschen 14 in einer Schrägstellung zur Längserstreckung der Tragschienen eingeführt und dann um die Mittelachse 19 so gedreht wird, daß die vom Ankersteg 22 und vom Mittelteil des Ankerkopfs 20 aufgespannte Ebene sich rechtwinklig zur Längsrichtung der Tragschienen erstreckt. Bei dieser Drehung gelangen die Randflanschen 14 der Trag­schiene in die Ausklinkungen 24 der seitlichen Halte­abschnitte 21 und werden von den bogenförmig ausge­bildeten unteren Begrenzungen 25 dieser Ausklinkungen hintergriffen. Die unterseitig an den Ankerkopf und die Halteabschnitte angeformten Füßchen 26, 27 stehen dann auf dem Profilsteg 11 der Tragschiene auf und der Ankerkopf ist zwischen dem genannten Profilsteg und den Tragschienen-Randflanschen 14 verspannt.The assembly of the anchor hanger 18 according to the invention on the support rails 10 is achieved in a simple manner by the anchor head 20 of the anchor hanger between the upwardly directed profile legs 12 of the support rails and the edge flanges 14 directed inwards from the free longitudinal edges of the profile legs in an oblique position to the longitudinal extension of the support rails introduced and then rotated about the central axis 19 such that the plane spanned by the anchor web 22 and by the central part of the anchor head 20 extends at right angles to the longitudinal direction of the mounting rails. During this rotation, the edge flanges 14 of the mounting rail come into the notches 24 of the lateral holding sections 21 and are engaged behind by the arched lower boundaries 25 of these notches. The feet 26, 27 formed on the underside of the anchor head and the holding sections then stand on the profile web 11 of the mounting rail and the anchor head is clamped between the said profile web and the mounting rail edge flanges 14.

Angesichts der oben beschriebenen Ausbildung des Anker­kopfs 20 mit den seitlichen Halteabschnitten 21 sind die in der vorstehend erläuterten Weise vormontierten Ankerhänger 18 lagerichtig in der jeweiligen Trag­schiene gehalten und der Anschluß der vormontierten Ankerhänger an ihrerseits an einer Rohbaudecke vor­montierten Mitteln zum Abhängen gelingt in einfacher Weise. Bei dem als Ausführungsbeispiel veranschau­lichten Ankerhänger ist mit dem Ankersteg 22 eine Klemmfeder 16 mittels Nieten 30 befestigt, die zwei sich nach der gleichen Seite vom Ankersteg divergierend zueinander forterstreckende Federschenkel 31 aufweist. Im Abstand von dem mit dem Ankersteg verbundenen Klemm­federsteg befinden sich fluchtend zueinander in den Klemmfederschenkeln 31 quer zu deren Längserstreckung verlaufende einseitig offene Querschlitze 32, die sich von gleichen Seiten aus in die Federschenkel hineinerstrecken. Durch diese Querschlitze werden beim Abhängen einer mit Ankerhängern ausgerüsteten Trag­schiene die an einer Rohbaudecke vormontierten Hänge­drähte 15 bei zusammengedrückten Federschenkeln ein­geführt und gelangen dann infolge der durch Loslassen der Federschenkel wirksam werdenden Federspannung mit den Schlitzrändern in Klemmlage. Dies bedarf im einzelnen keiner Erläuterung, weil derartige Klemm­halterungen bekannt sind.In view of the above-described design of the anchor head 20 with the lateral holding sections 21, the anchor hangers 18 preassembled in the manner described above are held in the correct position in the respective mounting rail and the connection of the preassembled anchor hangers to a preassembled ceiling means for hanging is easier Wise. In the anchor hanger illustrated as an exemplary embodiment, a clamping spring 16 is fastened to the anchor web 22 by means of rivets 30, which has two spring legs 31 which extend divergently towards one another from the anchor web. At a distance from the clamping spring web connected to the anchor web there are transverse slots 32 which are open on one side and are aligned with one another in the clamping spring legs 31 and extend transversely to their longitudinal extension and extend into the spring legs from the same sides. Through these transverse slots when hanging a support rail equipped with anchor hangers, the pre-assembled hanging wires 15 on a structural ceiling are inserted when the spring legs are compressed and then come into clamping position as a result of the spring tension that becomes effective when the spring legs are released. This requires no explanation in detail because such clamps are known.

Auch bei dem anhand der Fig. 7 bis 10 veranschaulich­ten Winkelanker 18′ handelt es sich um ein Blechformteil mit einem symmetrisch zu einer Mittellinie 19′ aus­gebildeten Ankerkopf 20′, der zwei seitliche Halte­abschnitte 21′ besitzt, und mit einem sich auf einer Seite vom Ankerkopf forterstreckenden Ankersteg 22′. Im Unterschied zu dem Ankerhänger nach den Fig. 1 bis 6 sind die sich aus der Ebene des Mittelteils des Ankerkopfs halbkreisbogenförmig forterstreckenden Halteabschnitte 21′ jedoch nicht mit seitlichen Aus­klinkungen versehen, sondern die zum Ankersteg 22′ hinweisenden Oberkanten 25′ sind in gleicher Weise wie die vom Ankersteg entfernten Begrenzungen 25 der Ausklinkungen 24 bei dem Ankerhänger 18 bogenförmig ausgebildet und untergreifen bei bestimmungsgemäßer Verwendung die nach einwärts abgekanteten Tragschienen-­Randflanschen 14. Auch bei dieser Ausführungsform sind auf der vom Ankersteg 22′ entfernten Seite Füßchen 27′ angeordnet, die sich bei bestimmungsgemäßer Ver­wendung am Tragschienen-Profilsteg 11 abstützen, so daß der Ankerkopf dann zwischen dem Profilsteg und den einwärts abgekanteten Randflanschen verspannt ist.7 to 10 illustrated angled anchor 18 'is a sheet metal part with a symmetrical to a center line 19' formed anchor head 20 ', which has two lateral holding portions 21', and with one on one side of the anchor head extending anchor bar 22 '. In contrast to the anchor hanger according to FIGS. 1 to 6, the holding sections 21 'extending from the level of the central part of the anchor head in a semicircular arc are not provided with lateral notches, but rather to the anchor web 22'. indicative upper edges 25 'are formed in the same way as the limits 25 of the notches 24 of the notches 24 in the anchor hanger 18 are arch-shaped and, when used as intended, engage under the inwardly bent support rail edge flanges 14. Also in this embodiment, the distance from the anchor web 22' Side feet 27 'arranged, which are supported when used as intended on the mounting rail profile web 11, so that the anchor head is then clamped between the profile web and the inwardly bent edge flanges.

Ebenfalls im Unterschied zu dem Ankerhänger 18 ist bei dem Winkelanker 18′ das vom Ankerkopf 20′ entfernte Ende des Ankerstegs 22′ als in der Montagelage abbieg­bare Haltelasche 35 ausgebildet und im Abstand vom Ankerkopf mit einer nach der gleichen Seite wie die halbkreisbogenförmigen Halteabschnitte 21′ ausgestellten Zunge 36 ausgerüstet, die etwa in einem der zweifachen Höhe der Profilschenkel 12 der Tragschienen entsprechen­den Abstand von der Unterseite des Ankerkopfs ange­ordnet ist. Im Bereich der ausgestellten Zunge ist das als abbiegbare Haltelasche ausgebildete freie Ende des Ankerstegs 22′ um etwa 45° gegenüber der vom übri­gen Ankersteg aufgespannten Ebene abgekantet.Also in contrast to the anchor hanger 18 is at the angled anchor 18 'from the anchor head 20' distant end of the anchor web 22 'formed as a bendable mounting bracket 35 and spaced from the anchor head with one on the same side as the semicircular holding sections 21' issued Tongue 36 equipped, which is arranged approximately at a distance twice the height of the profile legs 12 of the mounting rails from the underside of the anchor head. In the area of the flared tongue, the free end of the anchor web 22 ', which is designed as a bendable retaining tab, is bent by approximately 45 ° with respect to the plane spanned by the remaining anchor web.

Der Winkelanker 18′ nach den Fig. 7 bis 9 dient zum An­hängen C-förmiger Tragschienen 10′ an die Tragschienen 10 einer bereits abgehängten Unterkonstruktion, die aus den gleichen Tragschienen aufgebaut sein kann. Im Anwen­ dungsfall, der aus Fig. 10 ersichtlich ist, sind zwei Winkelanker mit ihren seitliche Halteabschnitte 21′ aufweisenden Ankerköpfen 20′ innerhalb des an eine Unterkonstruktion anzuhängenden C-förmigen Tragpro­fils 10′ aufgenommen, wobei die Oberkanten 25′ der seitlichen Halteabschnitte 21′ die nach einwärts abge­kanteten Randflanschen 14′ der Tragschiene untergreifen und die unterseitigen Füßchen 26′, 27′ auf dem Profilsteg 11′ der Tragschiene aufstehen. Dadurch ist eine sichere Halterung eines so montierten Winkelankers gewährleistet.The angle anchor 18 'according to FIGS. 7 to 9 is used for attaching C-shaped mounting rails 10' to the mounting rails 10 of an already suspended substructure, which can be constructed from the same mounting rails. In the application Example, which can be seen from Fig. 10, two angle anchors with their lateral holding sections 21 'having anchor heads 20' within the to be attached to a substructure C-shaped support profile 10 ', the upper edges 25' of the lateral holding sections 21 'the inwards reach under the folded edge flanges 14 'of the mounting rail and the feet 26', 27 'on the underside stand up on the profile web 11' of the mounting rail. This ensures a secure mounting of an angle anchor assembled in this way.

Die in der vorstehend erläuterten Weise mit vormontier­ten Winkelankern 18′ lagerichtig bestückte Tragschiene 10′ wird dann unterseitig derart zur Anlage an den Trag­schienen 10 einer bereits montierten Unterkonstruktion gebracht, daß die Ankerstege der beiden jeweils in einem der Breite der Tragschienen 10 der bereits mon­tierten Unterkonstruktion entsprechenden Abstand vonei­nander montierten Winkelanker 18′ sich beidseitig der Profilschenkel der zuletzt genannten Tragschiene hoch­erstrecken. In dieser Lage befinden sich die aus der Ebene der Ankerstege 22′ herausgeformten Zungen 36 auf der Höhe der Oberkanten 13 der bereits abgehängten Trag­schienen 10 und eine Festlegung der an dieser Unter­konstruktion abzuhängenden Tragschiene 10′ gelingt in einfacher Weise dadurch, daß die ausgestellten Zun­gen 36 der Ankerstege 22 auf die Oberkanten 13 der bereits abgehängten Tragschienen 10 aufgeclipt werden. Danach müssen lediglich noch die als abbiegbare Halte­laschen 35 ausgebildeten freien Enden der Ankerstege um die Oberkanten 13 der Tragschiene 10 der Unter­ konstruktion herumgebogen werden, um die mit den Win­kelankern ausgerüstete C-förmige Tragschiene 10′ lage­sicher an den Tragschienen der bereits abgehängten Unterkonstruktion anzuhängen. In Fig. 10 sind die Haltelaschen in gestrichelten Linien vor dem Abbiegen und in vollen Linien nach dem Abbiegen in ihre die Oberkanten der Profilschenkel der Tragschiene 10 über­greifende Haltelage gezeigt.The in the manner explained above with preassembled angle anchors 18 'correctly assembled support rail 10' is then brought on the underside to bear against the support rails 10 of an already assembled substructure that the anchor webs of the two corresponding to the width of the support rails 10 of the already assembled substructure Distance from each other angled anchor 18 'extend on both sides of the profile leg of the last-mentioned mounting rail. In this position, the tongues 36 are formed out of the plane of the anchor webs 22 'at the height of the upper edges 13 of the already suspended support rails 10 and a fixing of the support rail 10 to be suspended on this substructure is achieved in a simple manner by the tongues 36 being issued Anchor webs 22 are clipped onto the upper edges 13 of the already suspended support rails 10. Thereafter, only the free ends of the anchor webs, which are designed as bendable holding tabs 35, have to be around the upper edges 13 of the mounting rail 10 of the lower part construction are bent around to attach the C-shaped mounting rail 10 'equipped with the angled anchors securely to the mounting rails of the already suspended substructure. In Fig. 10, the holding tabs are shown in dashed lines before the turn and in full lines after the turn in their holding position overlapping the upper edges of the profile legs of the mounting rail 10.
