Description

Die Erfindung betrifft eine Tragschiene für Unterdecken mit von einem Schienenmittelteil nach außen abstehenden Schienenrändern zum Verankern von Clipsen, mit welchen Profilbretter oder -platten an der Tragschiene verankerbar sind.The invention relates to a mounting rail for suspended ceilings with rail edges projecting outwards from a central rail part for anchoring clips with which profile boards or plates can be anchored to the mounting rail.

Tragschienen dieser Art sind in Abhängekonstruktionen für die Unterdecken über Hänger an einer Gebäudedecke ver­ankert. Bei den bisher bekannten Abhängekonstruktionen werden nur geradlinig verlaufende Tragschienen verwendet.Supporting rails of this type are anchored in suspension structures for the suspended ceilings via hangers on a building ceiling. In the previously known suspension constructions, only linear support rails are used.

Der Erfindung liegt die Aufgabe zugrunde, eine Tragschiene zu schaffen, welche die Herstellung gewölbter Unterdecken erlaubt.The invention has for its object to provide a mounting rail which allows the production of curved ceilings.

Die gestellte Aufgabe wird mit einer eingangs genannten Tragschiene erfindungsgemäß dadurch gelöst, daß sie für gewölbte Unterdecken zum Krümmen in ihrem Schienenmittel­ teil in gleichmäßigen Abständen gleich dimensionierte, jeweils mit Abstand von einem der Schienenränder endende Einschnitte zum Ansetzen eines Spreizwerkzeuges und/oder eine Stauchung in Längsrichtung bewirkende Riffelungen aufweist und zusätzlich zwischen benachbarten Einschnit­ten, zwischen Einschnitten und den Schienenenden und/oder neben Riffelungen jeweils mit mindestens einer parallel zu den Einschnitten gerichteten Durchgangsöffnung zum Verankern von Kupplungsorganen, Sicherungsorganen oder Hänger-Elementen versehen ist.The stated object is achieved according to the invention with a mounting rail mentioned at the outset in that it is used for curved suspended ceilings to bend in its rail means partly has uniformly dimensioned, equally spaced incisions at a distance from one of the rail edges for attaching a spreading tool and / or corrugations causing compression in the longitudinal direction and additionally between adjacent incisions, between incisions and the rail ends and / or in addition to corrugations each with at least one is provided parallel to the incisions through opening for anchoring coupling elements, securing elements or hanger elements.

Tragschienen der einschlägigen Art sind aus dünnem Blech gefertigt und erhalten ihre Stabilität weitgehend durch ihre Profilierung und Ausbildung als U-Schiene oder T-Schiene. Die geringe Wandungsstärke der Tragschienen erlaubt kein Biegen der Schienen im Walzvorgang, wie dies beispielsweise bei Metallrohren mit größerer Wandungs­stärke vorgenommen wird, sondern es müssen zum Vermeiden eines Aufreißens der Schienen beim Biegevorgang Ein­schnitte in Aufweitungszonen und/oder eine Schienenkürzung bewirkende Riffelungen in Stauchzonen der zu biegenden Schienen vorgesehen werden. Durch die genau gleiche Dimen­sionierung der Einschnitte und/oder der Riffelungen wird erreicht, daß beim Einsatz von Spreizwerkzeugen oder auch beim jetzt möglichen Einsatz von Biegewalzen vorherbe­stimmbare Biegeradien eingehalten werden können. Die Durchgangsöffnungen in den Tragschienen erlauben u. a. auch die Anordnung von Sicherungsschienen und anderen Sicherungsorganen, mit welchen erreicht wird, daß die Tragschiene auch unter erhöhter Belastung die ihr vorge­gebene Biegung behält und sich nicht weiterverformt oder rückverformt.Support rails of the relevant type are made of thin sheet metal and largely maintain their stability through their profiling and design as a U-rail or T-rail. The low wall thickness of the mounting rails does not allow the rails to be bent in the rolling process, as is the case, for example, with metal pipes with a larger wall thickness, but rather to avoid tearing of the rails during the bending process, incisions in widening zones and / or corrugations causing a shortening of the rails in compression zones of the bends Rails are provided. The exact same dimensioning of the incisions and / or the corrugations ensures that predeterminable bending radii can be maintained when using spreading tools or also when using bending rollers. The through openings in the mounting rails allow, inter alia, the arrangement of securing rails and other securing devices, with which it is achieved that the mounting rail retains its predetermined bend even under increased load and does not deform or reshape.

Die erfindungsgemäß ausgebildete Tragschiene hat den Vor­teil, daß ihr an Ort und Stelle eine individuell gewünsch­te Krümmung erteilt werden kann. Die Tragschienen können aber auch mit einer vorgegebenen Krümmung vorgefertigt werden und beispielsweise aus einzelnen kürzeren und vor­gekrümmten oder einzeln krümmbaren Abschnitten zusammen­setzbar sein, wobei dann jeder Abschnitt im Schienenmit­telteil am einen Ende mit einem Steckvorsprung und am anderen Ende mit einer für den Steckvorsprung passenden Stecköffnung versehen ist und Durchgangsöffnungen im Zu­sammensteckbereich das Einbringen von Kupplungsorganen, insbesondere Kupplungsstiften, ermöglichen.The support rail designed according to the invention has the advantage that it can be given an individually desired curvature on the spot. However, the mounting rails can also be prefabricated with a predetermined curvature and, for example, be assembled from individual shorter and pre-curved or individually curvable sections, each section in the middle part of the rail then being provided with a plug-in projection at one end and with a plug-in opening suitable for the plug-in projection at the other end and through openings in the plug-in area enable the introduction of coupling members, in particular coupling pins.

Bei den vorzugsweise mit Biege-Einschnitten versehenen Tragschienen können die Biege-Einschnitte auch abschnitts­weise aus einzelnen Teileinschnitten bestehen, die beim Spreizen mittels eines Spreizwerkzeuges eine streckmetall­artige Verformung der betreffenden Wandungsbereiche erlau­ben, wobei durch diese Verformung gleichzeitig eine Siche­rung der Spreizlage der Tragschiene erzielbar ist. Bei U-förmigen Tragschienen kann durch eine Schrägführung der Biege-Einschnitte in der U-Basis sichergestellt werden, daß diese Tragschienen auch eine Biegewalzvorrichtung durchlaufen können, ohne daß die Walzen an den Einschnitt­stellen die Schienen verstärkt aufspreizen.In the case of the support rails, which are preferably provided with bend incisions, the bend incisions can also consist, in sections, of individual partial incisions which, when spreading by means of a spreading tool, permit an expanded metal-like deformation of the relevant wall areas, with this deformation at the same time securing the spreading position of the support rail. In the case of U-shaped support rails, an inclined guide of the bending incisions in the U-base can ensure that these support rails can also pass through a bending roller device without the rollers spreading apart the rails at the incision points.

Das Selbstbiegen der Tragschienen durch den Heimwerker läßt sich durch spezielle Spreizwerkzeuge erleichtern, die erfindungsgemäß ein in einen Biege-Einschnitt einsteck­bares Spreizende vorgegebener Breite und/oder vorgegebener Winkelstellung zu einem anschließenden Werkzeugschaft aufweisen, so daß die erzielbare Spreizwirkung auf einen vorbestimmten Spreizwinkel festgelegt wird. Ein solches Spreizwerkzeug kann einen beidseitig mit einem Spreizende ausgebildeten Schaft aufweisen, wobei die Spreizenden unterschiedliche Breite und/oder unterschiedliche Winkel­stellung aufweisen können. Auch kann ein bestimmter Spreizwinkel durch eine Begrenzung der Angriffsbewegung eines solchen Spreizwerkzeuges mittels eines vorzugsweise verstellbaren und lösbaren Anschlages erreicht werden.The self-bending of the mounting rails by the handyman can be facilitated by special spreading tools which, according to the invention, have a spreading end which can be inserted into a bending incision and have a predetermined width and / or predetermined angular position with respect to a subsequent tool shank, so that the achievable spreading effect is fixed at a predetermined spreading angle. Such one The expanding tool can have a shaft formed on both sides with an expanding end, wherein the expanding ends can have different widths and / or different angular positions. A certain spreading angle can also be achieved by limiting the attack movement of such a spreading tool by means of a preferably adjustable and releasable stop.

Die Verankerung der gekrümmten Tragschienen gemäß der Erfindung an einer Gebäudedecke kann nach wie vor mittels Hänger-Elementen in einer zusätzlich eine Versteifungswir­kung auf die gekrümmten Tragschienen ausübenden Abhänge­konstruktion erfolgen. Hierbei können erfindungsgemäß die Hänger-Elemente als an sich bekannte Hängeschienen ausge­bildet sein, die aber mindestens an ihrem einen Ende mit einem breiten, zur Anlage gegen die Tragschiene vorgesehe­nen Kupplungsteil versehen sind, das mindestens eine Loch­reihe aufweist, die auf einem Kreisbogen angeordnet ist. Diese Hänger-Elemente lassen sich unter einer vorgegebenen Winkelstellung mit der Tragschiene und/oder auch mit ande­ren Hänger-Elementen verbinden, indem an den Kupplungs­stellen mehrere, mindestens zwei Kupplungsstifte in mit­einander fluchtende Öffnungen von Hänger-Element und Trag­schiene eingebracht werden, eine gelenkige Kupplungsstelle also vermieden wird. Als Sicherungs- oder kombinierte Sicherungs- und Kupplungsorgane können auch U-förmige Klammern Verwendung finden, deren Schenkel in Öffnungen der Tragschiene einsteckbar sind. Eine eingestellte Spreizstellung einer Tragschiene kann auch mittels in die Biege-Einschnitte einbringbare Steckkeile vorgegebener Steigung gesichert werden.The curved support rails according to the invention can still be anchored to a building ceiling by means of hanger elements in an additional stiffening effect on the curved support rails. According to the invention, the hanger elements can be designed as hanging rails which are known per se, but which, at least at one end, are provided with a wide coupling part which is intended to bear against the mounting rail and which has at least one row of holes which is arranged on an arc of a circle. These hanger elements can be connected to the support rail and / or also to other hanger elements at a predetermined angular position by inserting several, at least two coupling pins into aligned openings of the hanger element and support rail at the coupling points, i.e. an articulated coupling point is avoided. U-shaped clips can also be used as securing or combined securing and coupling elements, the legs of which can be inserted into openings in the mounting rail. A set spread position of a mounting rail can also be secured by means of plug-in wedges of a predetermined pitch that can be inserted into the bending incisions.

Fig. 1 zeigt eine aus aneinandergereihten und miteinander verfugten Profilbrettern 11 zusammengesetzte gewölbte Unterdecke 10 mit ihrer Tragkonstruktion, die mit Abstand voneinander angeordnete gewölbte Tragschienen 15 aufweist, die über Hänger-Elemente 12, 13 und 14 an der Decke 16 und an den Seitenwandungen 17 eines Raumes verankert sind. Die Profilbretter 11 sind an den Tragschienen 15 in bekannter Weise mittels Clipsen 18 befestigt, von denen einer aus Fig. 3 ersichtlich ist.Fig. 1 shows an assembled from lined up and mutually jointed profile boards 11 curved ceiling 10 with its supporting structure, which has spaced-apart curved supporting rails 15, the hanging elements 12, 13 and 14 on the ceiling 16 and on the side walls 17 one Are anchored in the room. The profile boards 11 are fastened to the mounting rails 15 in a known manner by means of clips 18, one of which can be seen in FIG. 3.

Die Fig. 2 bis 7 zeigen verschiedene Ausführungsformen von Tragschienen, die zur Verankerung der Clipse 18 alle mit nach außen abstehenden Schienenrändern 19 versehen sind.2 to 7 show different embodiments of mounting rails, all of which are provided with rail edges 19 projecting outwards for anchoring the clips 18.

Fig. 2 zeigt einen Abschnitt der in Fig. 1 dargestellten, U-förmigen Tragschiene 15. Sie ist in regelmäßigen Abstän­den mit quer zu ihrer Längsrichtung verlaufenden Biege-­Einschnitten 20 versehen, die sich über die U-Basis 15.1 und über einen Teil der beiden U-Schenkel 15.2 der Trag­schiene 15 erstrecken. An diesen Biege-Einschnitten 20 läßt sich die Tragschiene 15 gemäß Fig. 3 zur Erzielung einer gewölbten Tragschiene aufspreizen. Zwischen den mit gleichmäßigen Abständen angeordneten Biege-Einschnitten 20 ist die Tragschiene 15 im Bereich der U-Basis 15.1 und im Bereich der U-Schenkel 15.2 mit Durchgangsöffnungen 21 und 22 versehen.FIG. 2 shows a section of the U-shaped support rail 15 shown in FIG. 1. It is provided at regular intervals with bending incisions 20 which run transversely to its longitudinal direction and extend over the U base 15.1 and over part of the two U-legs 15.2 of the mounting rail 15 extend. The carrier rail 15 according to FIG. 3 can be spread out at these bending incisions 20 in order to achieve a curved carrier rail. The support rail 15 is provided with through-openings 21 and 22 in the area of the U base 15.1 and in the area of the U legs 15.2 between the bending incisions 20 arranged at uniform intervals.

Fig. 4 zeigt eine Tragschiene 25 mit einem an sich bekann­ten T-Profil, die aus einem Metallblechstreifen gebogen ist und bei welcher der das Tragschienenmittelteil bilden­den T-Steg 25.1 durch zwei weitgehend gegeneinanderlie­gende Blechzuschnittsteile gebildet ist. Hier sind die Biege-Einschnitte 20 im T-Steg 25.1 ausgebildet, der eben­falls mit Durchgangsöffnungen 22 zwischen den einzelnen Biege-Einschnitten 20 versehen ist. In unmittelbarer Nach­barschaft der Biege-Einschnitte sind weitere Durchgangs­öffnungen 23 zum Einstecken von Sicherungsklammern vorge­sehen, die in Verbindung mit Fig. 7 beschrieben werden.Fig. 4 shows a mounting rail 25 with a known T-profile, which is bent from a sheet metal strip and in which the T-web 25.1 forming the mounting rail middle part is formed by two sheet metal parts which are largely opposite one another. Here, the bend incisions 20 are formed in the T-web 25.1, which is also provided with through openings 22 between the individual bend incisions 20. In the immediate vicinity of the bending incisions, further through openings 23 are provided for inserting securing clips, which are described in connection with FIG. 7.

Fig. 5 zeigt eine U-förmige Tragschiene 15 mit verschiede­nen Ausführungsformen der Biege-Einschnitte 20. Am linken Ende des Tragschienenabschnittes ist ein kleiner Biege-­Einschnitt 20, wie beim Ausführungsbeispiel nach Fig. 2 und 3 beidseitig mit in den U-Schenkeln 15.2 ausgebildeten Durchgangsöffnungen 23 versehen, dargestellt. In der Mitte und am rechten Ende des Tragschienenabschnittes sind da­gegen Biege-Einschnitte 20.1 und 20.2 dargestellt, die in den U-Schenkeln 15.2 der Tragschiene 15 in einzelne Ein­schnittabschnitte 24 unterteilt sind. Diese einzelnen Ein­schnittabschnitte 24 ergeben beim Aufspreizen der Ein­schnitte 20.1 und 20.2 eine Verformung der zwischen ihnen liegenden Wandungsbereiche, ähnlich wie bei der Herstel­lung von Streckmetall, und die auftretende Wandungsverfor­mung bewirkt wiederum eine Stabilisierung der Tragschiene 15 an den Aufspreizstellen zur Sicherung der durchgeführ­ten Aufspreizung.FIG. 5 shows a U-shaped mounting rail 15 with different embodiments of the bending incisions 20. At the left end of the mounting rail section is a small bending incision 20, as in the embodiment according to FIGS. 2 and 3, formed on both sides in the U-legs 15.2 Through openings 23 provided, shown. In the middle and at the right end of the mounting rail section, however, bending incisions 20.1 and 20.2 are shown, which are shown in the U-legs 15.2 of the mounting rail 15 are divided into individual incision sections 24. During the spreading of the incisions 20.1 and 20.2, these individual incision sections 24 result in a deformation of the wall areas lying between them, similar to the production of expanded metal, and the resulting wall deformation in turn causes a stabilization of the mounting rail 15 at the spreading points to secure the spreading.

Um eine genau bestimmte Aufspreizung und damit eine ge­wünschte vorgegebene Krümmung der Tragschiene 15 zu er­reichen, werden aus den Fig. 6, 8, 9 und 10 ersichtliche Spreizwerkzeuge verwendet. Fig. 6 zeigt ein Spreizwerkzeug 26 mit einem stegartigen Schaft 27, der an beiden Enden rechtwinklig abgebogen und im abgebogenen Teil als Spreiz­ende 28 und 29 mit genau vorgegebener Breitenabmessung ausgebildet ist. Das Spreizende 28 ist relativ schmal gehalten. Es läßt sich in einen verbreiterten Mittelteil 30 der Biege-Einschnitte 20, 20.1 oder 20.2 einsetzen. Durch eine Drehung des Schaftes 27 des Spreizwerkzeuges 26 um 90° wird eine Aufspreizung um einen durch die Breite des Spreizendes 28 genau vorgegebenen Spreizwinkel er­zielt. Das Spreizende 29 des Spreizwerkzeuges 26 ist brei­ter gehalten. Mit diesem Spreizende wird beim Drehen des angesetzten Spreizwerkzeuges 26 ein größerer Spreizwinkel erzielt, wie in Fig. 6 am Biege-Einschnitt 20.2 darge­stellt ist.In order to achieve a precisely determined spreading and thus a desired predetermined curvature of the mounting rail 15, spreading tools shown in FIGS. 6, 8, 9 and 10 are used. 6 shows a spreading tool 26 with a web-like shank 27 which is bent at right angles at both ends and is formed in the bent part as a spreading end 28 and 29 with a precisely predetermined width dimension. The spreading end 28 is kept relatively narrow. It can be inserted into a widened middle part 30 of the bending incisions 20, 20.1 or 20.2. By rotating the shaft 27 of the spreading tool 26 by 90 °, a spreading is achieved by a spreading angle which is precisely predetermined by the width of the spreading end 28. The spreading end 29 of the spreading tool 26 is kept wider. With this spreading end, a larger spreading angle is achieved when the attached spreading tool 26 is rotated, as shown in FIG. 6 on the bending incision 20.2.

Die an den Biege-Einschnitten 20 eingestellten Spreiz­winkel können mittels aus Fig. 7 ersichtlicher Organe gesichert werden. Es können dies aus Blechabschnitten gebogene Keile 31 oder 32 mit passenden Keilwinkeln sein, oder aber Klammern 33 und 34 oder Bügel 35, 36 unter­schiedlicher Breite bzw. Länge. Die Klammern 33 und 34 können in aus Fig. 7 ersichtliche schlitzförmige Durch­gangsöffnungen 23.1 eingesetzt werden, die zu beiden Sei­ten eines Biege-Einschnittes in den U-Schenkeln 15.2 der U-förmigen Tragschiene ausgebildet sind. Die Klammern 35 und 36 können nach dem Aufspreizen der Biege-Einschnitte 20 in schlitzförmige Ausnehmungen 37 eingesetzt werden, die in der U-Basis 15.1 der Tragschiene 15 ausgebildet sind. Fig. 7 zeigt weitere mögliche Ausbildungsformen der Biege-Einschnitte 20.The spreading angles set on the bending incisions 20 can be secured by means of organs shown in FIG. 7. These can be wedges 31 or 32 bent from sheet metal sections with suitable wedge angles, or clips 33 and 34 or brackets 35, 36 of different widths or lengths. The clamps 33 and 34 can be inserted into the slot-shaped through openings 23.1 shown in FIG. 7, which are formed on both sides of a bending incision in the U-legs 15.2 of the U-shaped mounting rail. After the bending incisions 20 have been spread open, the clamps 35 and 36 can be inserted into slot-shaped recesses 37 which are formed in the U-base 15.1 of the mounting rail 15. 7 shows further possible forms of formation of the bending incisions 20.

Fig. 8 zeigt ein an einer Tragschiene 15 angesetztes Spreizwerkzeug 38. Die beiden Spreizenden 39 und 40 sind mit unterschiedlichen Winkeln zum Schaft 41 des Spreiz­werkzeuges 38 angeordnet und ergeben somit beim Nieder­drücken des Schaftes 41 gegen die U-Basis der Tragschiene 15 unterschiedlich starke Aufspreizungen der Einschnitte 20. Auf dem Schaft 41 ist ein Anschlag 42 verschiebbar ge­lagert, der - je nach seiner Stellung auf dem Schaft 41 - den Hebelweg des Spreizwerkzeuges 38 mehr oder weniger stark begrenzt und damit unterschiedliche Spreizwinkel an den Stellen der Biege-Einschnitte 20 ergibt. Anstelle eines verschiebbaren Anschlages 42 kann ein Spreizwerkzeug 38.1 an festgelegten Stellen seines Schaftes 41 mit Ge­windebohrungen 43 versehen sein, in welche als Anschläge wirkende Schrauben 44 einsetzbar sind, die den Hebelweg des Spreizwerkzeuges 38.1 unterschiedlich stark begrenzen. Eine solche Ausführungsform eines Biegewerkzeuges ist in Fig. 9 dargestellt.8 shows an expansion tool 38 attached to a support rail 15. The two expansion ends 39 and 40 are arranged at different angles to the shaft 41 of the expansion tool 38 and thus, when the shaft 41 is pressed down against the U-base of the support rail 15, spreads of different strengths Incisions 20. On the shaft 41 a stop 42 is slidably mounted, which - depending on its position on the shaft 41 - limits the leverage of the expanding tool 38 to a greater or lesser extent and thus results in different spreading angles at the locations of the bending incisions 20. Instead of a displaceable stop 42, an expanding tool 38.1 can be provided at fixed points on its shaft 41 with threaded bores 43, into which screws 44 acting as stops can be used, which limit the leverage of the expanding tool 38.1 to different extents. Such an embodiment of a bending tool is shown in FIG. 9.

Fig. 10 zeigt ein zangenförmiges Spreizwerkzeug 45 mit zwei gelenkig miteinander verbundenen Hebeln 46 und 47, deren eines Ende jeweils als Spreizende 48 ausgebildet ist, die beim Gegeneinanderbewegen der beiden Schenkel 46 und 47 ein Aufspreizen einer Tragschiene 15 bei in einen Biege-Einschnitt 20 eingesetzten Spreizenden 48 bewirkt. Hier läßt sich der erzielbare Spreizwinkel mittels einer Stellschraube 49 einstellen.Fig. 10 shows a pliers-shaped expanding tool 45 with two articulated levers 46 and 47, one end of which is designed as an expanding end 48, which when the two legs 46 and 47 move against one another, a support rail 15 is spread open when inserted into a bending incision 20 Spreading ends 48 causes. Here the achievable spreading angle can be set by means of an adjusting screw 49.

Die Fig. 11 und 12 zeigen ein mit einer Tragschiene 15 verbundenes Hänger-Element 12 mit U-förmigem Querschnitt, mit welchem die Tragschiene 15 mit einer Hängerschiene 13 gekoppelt ist. Das Hänger-Element 12 und die Hängerschiene 13 sind in ihren U-Schenkeln jeweils mit einer Reihe von Löchern 52 und 53 versehen, die in Fluchtstellung mitein­ander bringbar sind und durch welche einfache Nägel 54 als Verbindungsorgane einsteckbar sind. Das Hänger-Element 12 ist zusätzlich an mindestens einem seiner beiden Enden in den U-Schenkeln mit einer auf einem Kreisbogen angeordne­ten Lochreihe 51 versehen, wobei die Abstände der Löcher der Lochreihe 51 von einem Loch der Lochreihe 52 auf den gegenseitigen Abstand von Durchgangsöffnungen 22 der Trag­schiene 15 abgestimmt sind. Die Befestigung der Trag­schiene 15 am Hänger-Element 12 erfolgt mittels zweier Nägel 54.1, von denen einer durch ein Loch der Lochreihe 52 des Hänger-Elementes 12 und durch eine Durchgangsöff­nung 22 eingesteckt ist, während der andere Nagel 54.1 in ein Loch der bogenförmig verlaufenden Lochreihe 51 und eine Durchgangsöffnung 22 der Tragschiene 15 eingesteckt ist. Durch die Koppelung mittels zweier Nägel 54.1 kann eine bestimmte Winkelstellung der Hänger-Elemente 12 zur Tragschiene 15 festgelegt werden, wie dies aus Fig. 17 ersichtlich ist.11 and 12 show a hanger element 12 connected to a support rail 15 with a U-shaped cross section, with which the support rail 15 is coupled to a hanger rail 13. The hanger element 12 and the hanger rail 13 are each provided in their U-legs with a series of holes 52 and 53 which can be brought into alignment with one another and through which simple nails 54 can be inserted as connecting elements. The hanger element 12 is additionally provided on at least one of its two ends in the U-legs with a row of holes 51 arranged on a circular arc, the distances of the holes of the row of holes 51 from a hole of the row of holes 52 to the mutual distance from through openings 22 Support rail 15 are matched. The mounting rail 15 is fastened to the hanger element 12 by means of two nails 54.1, one of which is inserted through a hole in the row of holes 52 of the hanger element 12 and through a passage opening 22, while the other nail 54.1 is inserted in a hole in the arched row of holes 51 and a through opening 22 of the mounting rail 15 is inserted. By coupling by means of two nails 54.1 can a certain angular position of the hanger elements 12 relative to the mounting rail 15 can be determined, as can be seen from FIG. 17.

Fig. 13 zeigt von einer aus mehreren gekrümmten Abschnit­ten 55 zusammengesetzten Tragschiene 56 die Verbindungs­stelle zwischen zwei Abschnitten 55. Es kann sich hier um U-förmige oder aber T-förmige Tragschienen handeln. Am einen Ende der Tragschienenabschnitte 55 ist ihr Mittel­teil mit einem ohne seitliche abstehende Ränder 19 ver­sehenen Steckvorsprung 57 versehen, der in eine am anderen Ende des Abschnittes 55 ausgebildete Stecköffnung paßt. Nach dem Einstecken des Vorsprunges 57 in die nicht be­zeichnete passende Stecköffnung des anschließenden Trag­schienenabschnittes 55 werden U-förmige Brückenteile 58 über die Verbindungsstelle geschoben, die mit Durchgangs­öffnungen 59 versehen sind, die mit Durchgangsöffnungen 22 der Tragschienenabschnitte 55 zur Deckung gebracht werden können, so daß Kupplungsstifte 60 einsteckbar sind. Die Brückenteile 58 können gemäß Fig. 14 auch als mit einem Einschnitt 20.3 versehene Brückenteile 58.1 ausgebildet sein, die an den Einschnittstellen 20 auf eine Tragschiene 15 zur Verstärkung oder Biegungssicherung anordenbar sind. Fig. 14 zeigt auch ein Hänger-Element 12, das unter einer festgelegten Winkelstellung mit der Tragschiene 56 verbun­den und durch die Kupplungsstifte 54.1 in dieser Stellung gesichert ist.FIG. 13 shows the connection point between two sections 55 of a support rail 56 composed of a plurality of curved sections 55. These can be U-shaped or T-shaped support rails. At one end of the mounting rail sections 55, its middle part is provided with a plug-in projection 57 which has no laterally projecting edges 19 and which fits into a plug-in opening formed at the other end of section 55. After the projection 57 has been inserted into the matching plug-in opening (not designated) of the subsequent mounting rail section 55, U-shaped bridge parts 58 are pushed over the connection point, which are provided with through openings 59 which can be brought into alignment with through openings 22 of the mounting rail sections 55, so that coupling pins 60 can be inserted. 14 can also be designed as bridge parts 58.1 provided with an incision 20.3, which can be arranged at the incision points 20 on a support rail 15 for reinforcement or bending protection. 14 also shows a hanger element 12 which is connected to the mounting rail 56 at a fixed angular position and is secured in this position by the coupling pins 54.1.

Fig. 15 zeigt ein anderes Hänger-Element 61 in Form einer Verbindungsplatte, an deren Ende auf einem Kreis eine Lochreihe 62 um ein Mittelpunktsloch 63 herum ausgebildet ist, während das andere Ende des Hänger-Elementes 61 in bekannter Weise U-förmig zum Umfangen einer Hängerschiene 13 ausgebildet ist. Die kreisbogenförmig angeordnete Loch­reihe 62 erlaubt wiederum die bereits in Verbindung mit den Fig. 11 und 14 beschriebene Festlegung einer gewünsch­ten oder erforderlichen Winkelstellung des Hänger-Elemen­tes 61 zu einer Tragschiene 15, 25 oder 56.Fig. 15 shows another hanger element 61 in the form of a connecting plate, at the end of which a row of holes 62 is formed on a circle around a center hole 63, while the other end of the hanger element 61 is U-shaped in a known manner to encircle one Hanger rail 13 is formed. The row of holes 62 arranged in a circular arc in turn allows the desired or required angular position of the hanger element 61 with respect to a mounting rail 15, 25 or 56, which has already been described in connection with FIGS. 11 and 14.

Fig. 16 zeigt ein Hänger-Element 12.1, das ähnlich wie das aus Fig. 11 und Fig. 14 ersichtliche Hänger-Element 12 ausgebildet ist. Es weist an beiden, einseitig abgerunde­ten Enden seiner U-Schenkel auf einem Kreisbogen angeord­nete Löcher 55 und jeweils ein zugehöriges Mittelpunkts­loch 63 auf. Auch in seiner U-Basis 64 sind Löcher 65 aus­gebildet.FIG. 16 shows a hanger element 12.1, which is designed similarly to the hanger element 12 shown in FIGS. 11 and 14. It has holes 55 arranged on a circular arc at both ends of its U-legs which are rounded on one side and each has an associated center hole 63. Holes 65 are also formed in its U-base 64.

Fig. 17 zeigt an einer gekrümmten Tragschiene 15 angrei­fende Hänger-Elemente 12, von denen eines als Querverstei­fungssteg zwischen einer Hängerschiene 13 und der gekrümm­ten Tragschiene 15 in Querlage angeordnet und in dieser Relativstellung zur Tragschiene wiederum mit zwei Kupp­lungsstiften 54.1 gesichert ist. Anstelle von Hänger-Ele­menten 12 könnten hier auch Hänger-Elemente 61 gemäß Fig. 15 eingesetzt werden.Fig. 17 shows on a curved support rail 15 engaging hanger elements 12, one of which is arranged as a transverse stiffening web between a suspension rail 13 and the curved support rail 15 in the transverse position and in this position relative to the support rail is in turn secured with two coupling pins 54.1. Instead of hanger elements 12, hanger elements 61 according to FIG. 15 could also be used here.

Fig. 18 zeigt einen Abschnitt einer Tragschiene 15, deren Biege-Einschnitte 66 in der U-Basis 15.1 pfeilförmig und damit schräg zur Schienenlängsrichtung verlaufen, wodurch die Tragschiene 15 bevorzugt in einer mit Biegewalzen ver­sehenen Biegeeinrichtung bearbeitet werden kann, wie auch die in Fig. 19 dargestellte Tragschiene 70. Die Trag­schiene 70 weist keine Biege-Einschnitte, sondern Riffe­lungen 67 in den Schienenrändern 19 und eine Riffelung 68 in den U-Schenkeln 70.2 der U-Schiene auf. Die einzelnen Sicken der Riffelung 68 erstrecken sich von den Schienen­ rändern 19 aus unterschiedlich weit in die U-Schenkel 70.2 hinein. Die Riffelungen 67, 68 erlauben ein Stauchen der Tragschiene 70 und dadurch eine genaue und kontinuierliche Biegung der Tragschiene 70.18 shows a section of a mounting rail 15, the bending incisions 66 of which are arrow-shaped in the U-base 15.1 and thus run obliquely to the longitudinal direction of the rail, as a result of which the mounting rail 15 can preferably be processed in a bending device provided with bending rollers, as is also the case in FIG. 19 support rail 70 shown. The support rail 70 has no bending incisions, but corrugations 67 in the rail edges 19 and a corrugation 68 in the U-legs 70.2 of the U-rail. The individual beads of the corrugation 68 extend from the rails edges 19 from different distances into the U-leg 70.2. The corrugations 67, 68 allow the mounting rail 70 to be compressed and thereby an exact and continuous bending of the mounting rail 70.
