Die Erfindung betrifft eine metallische Deckenunterkonstruktion für Deckenelemente, die aus sich kreuzenden, von der Decke beabstandeten Metallträgern besteht. Die Metallträger bilden dabei ein Raster und sind in Form von Haupt- und Querträgern ausgebildet. Die Verbindung der Metallträger untereinander wird dabei durch speziell ausgebildete Konnektoren realisiert, die in Öffnungen, die im Stegbereich der Metallträger angeordnet sind, eingreifen und die einzelnen Metallträger untereinander verrasten.The invention relates to a metallic ceiling substructure for ceiling elements, which consists of intersecting, spaced from the ceiling metal beams.

In der US 6,199,343 B1 ist eine derartige metallische Deckenunterkonstruktion beschrieben. Bei dieser aus dem Stand der Technik vorbekannten Unterkonstruktion wird ebenfalls ein Raster durch Verrastung von Haupt-und Querträgern gebildet. Die dort beschriebenen Haupt- und Querträger sind dabei in Form eines T-Profils ausgebildet. Die Verrastung erfolgt hierbei bereits durch Konnektoren, die an den Stirnseiten der Metallträger angeordnet sind und durch eine Öffnung, die im Stegbereich der Metallträger angeordnet ist, greifen. Die Öffnung in den T-Trägern ist dabei in einer speziellen Rechteckform ausgebildet. Es hat sich nun aber gezeigt, dass die Verrastung der Konnektoren durch die in der US 6,199,343 B1 beschriebene Öffnung zeitaufwändig ist. Auch ist es schwierig, die Verrastung, dann, wenn es gewünscht ist, wieder zu lösen.In the US 6,199,343 B1 Such a metallic ceiling substructure is described. At this off The prior art prior art substructure is also a grid formed by locking of main and cross members. The main and transverse beams described therein are designed in the form of a T-profile.

Ein weiteres vergleichbares System ist in der US 4,779,394 offenbart. Auch gemäß diesem US-Patent wird vorgeschlagen, eine metallische Deckenunterkonstruktion dadurch zu bilden, dass Haupt- und Querträger über Konnektoren verrastet werden. In dem US-Patent US 4,779,394 ist zwar eine spezielle Ausbildung der Öffnung im Stegbereich der Metallträger vorgesehen, jedoch ist auch die gegenseitige Verrastung der beiden Querträger mit dem Hauptträger umständlich und zeitaufwändig. Auch ist nicht ohne weiteres ein Lösen der verrasteten Verbindung möglich.Another comparable system is in the US 4,779,394 disclosed. It is also proposed according to this US patent to form a metallic ceiling substructure in that the main and transverse beams are latched via connectors.

The crossing points of the grid are formed by connectors which are arranged at the front ends of the cross members and which are latched to one another via openings in the web region of the metal carriers.

Wesentlich bei der erfindungsgemäßen Deckenunterkonstruktion ist, dass die Metallträger eine Öffnung mit einer rechteckigen Grundform aufweisen, wobei jeweils mittig an den kurzen Seiten des Rechtecks und jeweils an den Längsseiten des Rechtecks in der gleichen Höhe Vorsprünge in Richtung des Inneren der Öffnung ausgebildet sind. Diese speziell ausgebildeten Öffnungen wirken dann mit den Konnektoren, wie sie erfindungsgemäß vorgeschlagen werden, nämlich mit Konnektoren, die an ihren Längsseiten jeweils Abkantungen aufweisen, zusammen.
Durch eine derartige Konstruktion wird nun erreicht, dass ein sicheres und einfaches Verrasten der Metallträger untereinander gewährleistet ist. Es hat sich auch gezeigt, dass durch die spezifische Ausbildung der Öffnung und der Konnektoren auch ein leichtes und problemloses Trennen der Träger untereinander ermöglicht wird. Es hat sich weiterhin gezeigt, dass durch die spezifische Ausbildung der Konnektoren mit den Abkantungen, die eine Omega-Form bilden, dann, wenn die Metallträger miteinander verrastet sind, eine deutlich bessere Stabilität und Festigkeit erreicht wird. Auch hat es sich gezeigt, dass die Verwindungssteifigkeit mit derartigen "Omega-Konnektoren" deutlich verbessert wird.
Vorteilhaft ist weiterhin bei der erfindungsgemäßen Lösung, dass die Vorsprünge, d.h. die Vorsprünge sowohl an der kurzen Seite des Rechtecks als auch diejenigen, die an den Längsseiten angeordnet sind, aus dem Material der metallischen Träger selbst herausgearbeitet sind. Dadurch können in einem einfachen Produktionsgang bei der Herstellung der metallischen Träger gleichzeitig die Vorsprünge mit ausgebildet werden. Die Vorsprünge sind an der Längsseite im oberen von der Flanschseite abgewandten Bereich ausgebildet. Diese Vorsprünge sind an den Längsseiten im oberen Drittel. Ganz besonders bevorzugt im oberen Viertel, besonders bevorzugt im oberen Fünftel, angeordnet. Die Vorsprünge und die Öffnung selbst sind dabei dann so dimensioniert, dass sie zur Führung der durch die Öffnung hindurch führenden Konnektoren geeignet sind. Erfindungsgemäß sind somit die Größenverhältnisse des Rechtecks direkt auf den Konnektor abgestimmt.
Die Konnektoren selbst sind dabei, wie an und für sich bekannt, an den stirnseitigen Enden der Querträger über mindestens eine Verbindungseinrichtung, bevorzugt eine Verpressung und/oder Niete, befestigt. Die Konnektoren, die an den stirnseitigen Enden der Querträger befestigt sind, ragen dann selbstverständlich über das stirnseitige Ende der Querträger hinaus. Die Konnektoren sind dabei in ihrer Dimensionierung und Ausgestaltung so aufeinander abgestimmt, dass sie in Kombination mit den Öffnungen im Stegbereich der Metallträger zusammen wirken. Wesentlich dabei ist, dass jeder Konnektor jeweils beidseitig an den Längsseiten eine Abkantung aufweist, die mit den Vorsprüngen zusammenwirkt.
Grundsätzlich ist die spezifische Form des Konnektors im Sinne der Erfindung nicht begrenzt. Gemäß der vorliegenden Erfindung können dabei die Konnektoren, sofern sie die vorstehend beschriebenen Abkantungen in Omega-Form aufweisen, sowohl als Haken-Konnektoren als auch als Klick-Konnektoren ausgebildet sein.
Die Haken-Konnektoren, die gemäß der Erfindung eingesetzt werden können, sind dabei so aufgebaut, dass der Konnektor selbst zwei Öffnungen aufweist, die beide in dem das stirnseitige Ende des Stegbereiches überragenden Teil ausgebildet sind. Die beiden Öffnungen können dabei entweder plan, oder, was bevorzugt ist, so ausgebildet sein, dass die erste Öffnung, und zwar diejenige, die dem stirnseitigen Ende des Steges zugewandt ist, in etwa Rechteckform besitzt und nach außen aufgewölbt ist. Die zweite Öffnung ist dabei so ausgebildet, dass jeweils die aufgewölbte Öffnung des anderen Konnektors des Querträgers in die zweite Öffnung eingreifen kann. Dadurch wird eine nochmalige Stabilisierung der Verrastverbindung bewerkstelligt.It is essential in the case of the ceiling substructure according to the invention that the metal supports have an opening with a rectangular basic shape, with projections in the direction of the interior of the opening being formed centrally on the short sides of the rectangle and on the longitudinal sides of the rectangle at the same height are. These specially designed openings then act together with the connectors as they are proposed according to the invention, namely with connectors which have respective bends on their longitudinal sides.
By such a construction is now achieved that a secure and easy locking of the metal support is ensured with each other. It has also been shown that the specific design of the opening and the connectors also enables easy and problem-free separation of the carriers from one another. It has also been found that by the specific design of the connectors with the bends forming an omega shape, when the metal beams are locked together, a significantly better stability and strength is achieved. It has also been shown that the torsional stiffness is significantly improved with such "omega connectors".
A further advantage of the solution according to the invention is that the projections, ie the projections both on the short side of the rectangle and those which are arranged on the longitudinal sides, are machined out of the material of the metallic carrier itself. As a result, in a simple production process, the protrusions can be formed simultaneously with the manufacture of the metallic supports. The projections are formed on the longitudinal side in the upper region facing away from the flange side. These projections are on the long sides in the upper third. Most preferably arranged in the upper quarter, particularly preferably in the upper fifth. The projections and the opening itself are then dimensioned so that they are suitable for guiding the connectors passing through the opening. According to the invention, the size ratios of the rectangle are thus matched directly to the connector.
The connectors themselves are, as known per se, attached to the front ends of the cross member via at least one connecting device, preferably a compression and / or rivets. The connectors, which are attached to the front ends of the cross member, then protrude beyond the front end of the cross member, of course. The connectors are matched in their dimensioning and design so that they work together in combination with the openings in the web area of the metal support. It is essential that each connector has a fold on both sides of the long sides, which cooperates with the projections.
In principle, the specific form of the connector is not limited in the sense of the invention. According to the present invention, the connectors, if they have the above-described folds in omega form, can be designed both as hook connectors and as click connectors.
The hook connectors, which can be used according to the invention, are constructed so that the connector itself has two openings, both in the front end of the web area superior part are formed. The two openings can either be flat, or, which is preferred, be formed so that the first opening, namely the one which faces the front end of the web, has approximately rectangular shape and is arched outwardly. The second opening is designed so that in each case the bulged opening of the other connector of the cross member can engage in the second opening. As a result, a further stabilization of the Verrastverbindung is accomplished.

Der wie vorstehend beschriebene Haken-Konnektor zeichnet sich weiterhin dadurch aus, dass er im abgekanteten Bereich, und zwar auf der der Flanschseite abgewandten Seite eine bogenförmige Vertiefung und eine zusätzliche Nase aufweist. Durch diese spezifische Ausbildung der bogenförmigen Vertiefung mit der Nase wird gewährleistet, dass dann im verrasteten Zustand ein leichtes Lösen der Rastverbindung möglich wird. Wenn nämlich dann eine der Schienen, bevorzugt der Hauptträger, zur Seite gedrückt wird, löst sich die Nase von ihrem Auflagepunkt und der Querträger kann dann über ihre Öffnung herausgezogen werden. Der erfindungsgemäß vorgeschlagene Haken-Konnektor, der an seinem freien Ende einen Haken aufweist, zeichnet sich somit dadurch aus, dass er ebenfalls Omega-Form besitzt und dass er neben der Nase eine bogenförmige Vertiefung im abgekanteten Bereich aufweist.The hook connector as described above is further characterized in that it has an arcuate recess and an additional nose in the folded portion, on the side facing away from the flange side. This specific design of the arcuate recess with the nose ensures that then in the locked state easy release of the locking connection is possible. Namely, when one of the rails, preferably the main carrier is pushed aside, the nose releases from its support point and the cross member can then be pulled out through its opening. The inventively proposed hook connector, which has a hook at its free end, thus characterized by the fact that he also has omega shape and that he next to the nose has an arcuate recess in the folded portion.

Wie vorstehend bereits erläutert, umfasst die Erfindung dabei aber auch andere Ausgestaltungen, nämlich mittels einer Öffnung im Konnektor oder auch zwei, die jeweils auch plan sein können. Auch umfasst die Erfindung Ausführungsformen, die ohne Öffnung im Konnektor ausgebildet sind.However, as already explained above, the invention also encompasses other embodiments, namely by means of an opening in the connector or else two, which can each also be planar. Also, the invention includes embodiments that are formed without opening in the connector.

Erfindungsgemäß können aber zur Verrastung von Querträgern mit dem Hauptträger oder den Querträgern untereinander nicht nur die vorstehend beschriebenen Haken-Konnektoren eingesetzt werden, sondern die Verrastung kann auch mittels sog. Klick-Konnektoren erfolgen. Derartige Klick-Konnektoren sind im Prinzip im Stand der Technik bekannt. Gemäß der vorliegenden Erfindung wird aber nun vorgeschlagen, einen Klick-Konnektor zu verwenden, der ebenfalls wiederrum die vorstehend schon beim Haken-Konnektor beschriebene Omega-Form besitzt. Der Klick-Konnektor gemäß der Erfindung zeichnet sich somit auch dadurch aus, dass er die vorstehend beschriebenen Abkantungen aufweist, so dass eine Omega-Form des Klick-Konnektors entsteht und wobei dann in dem zwischen den beiden Abkantungen aufgespannten Bereich eine Feder angeordnet ist. Die Ausbildung der Feder ist an und für sich im Stand der Technik bekannt. Unterschiedlich zum Stand der Technik ist allerdings, wie vorstehend bereits beschrieben, dass auch der Klick-Konnektor durch die Abkantungen Omega-Form besitzt.According to the invention but not only the hook connectors described above can be used for latching cross members to the main carrier or the cross members with each other, but the locking can also be done by means of so-called. Click connectors. Such click connectors are known in the art in principle. However, according to the present invention, it is now proposed to use a click connector, which in turn also has the omega shape already described above for the hook connector. The click connector according to the invention is therefore also characterized in that it has the above-described folds, so that an omega-shape of the click connector is formed and in which case a spring is arranged in the area between the two folds. The design of the spring is in and of itself known in the art. However, unlike the prior art, as already described above, the click connector also has an omega shape due to the folds.

Durch die nun erfindungsgemäß vorgeschlagene spezifische Ausbildung des Konnektors in Omega-Form in Zusammenwirken mit den Vorsprüngen der Öffnung kann nun auch erreicht werden, dass nicht nur identische Konnektoren untereinander, d.h. Klick-Konnektoren oder Haken-Konnektoren, zur Verrastung benutzt werden, sondern es ist auch eine Verrastung möglich, in der Weise, dass an einem Querträger im stirnseitigen Ende ein Klick-Konnektor und am anderen stirnseitigen Ende des zweiten Querträgers z.B. ein Haken-Konnektor angeordnet ist. Durch die Omega-Form ist auch eine Verrastung dieser beiden unterschiedlichen Konnektortypen gewährleistet.By now proposed according to the invention specific design of the connector in omega shape in cooperation with the projections of the opening can now be achieved that not only identical connectors with each other, ie click connectors or hook connectors, are used for locking, but it is Also, a latching possible, in such a way that on a cross member in the front end of a click connector and at the other end face of the second cross member, for example, a hook connector is arranged. The omega shape also ensures locking of these two different connector types.

Bei der erfindungsgemäßen metallischen Deckenunterkonstruktion erfolgt dabei wie vorstehend beschrieben eine Verrastung mittels der vorstehend beschriebenen Konnektoren zwischen zwei Querträgern und dem Hauptträger. Bei der metallischen Deckenunterkonstruktion gemäß der Erfindung ist dabei dann auch noch, wie es auch schon aus dem Stand der Technik bekannt ist, vorgesehen, dass die Querträger wiederrum untereinander verrastet sein können. In diesem Fall weisen dann auch die Querträger im Stegbereich die zuvor beschriebene Öffnung auf. Eine Verrastung erfolgt dann mit zwei weiteren Querträgern mit den zuvor beschriebenen Konnektoren. Durch ein derartiges System kann dann ein Raster aufgebaut werden, wie es sich bereits bisher im Stand der Technik als bekannt durchgesetzt hat. Bei derartigen Rastern ist wesentlich, dass die von der Industrie hergestellten Deckenplatten, die ein Normmaß besitzen, in das entsprechende Raster eingehängt werden können. Dazu ist gemäß der Erfindung der Hauptträger 3 bis 4 m lang, bevorzugt 3,6 m bzw. 3,75 m, und der Querträger besitzt eine Länge von 0,5 m bis 2,0 m, bevorzugt 0,6 m bis 0,625 m und 1,2 m bzw. 1,25 m.As described above, in the case of the metallic ceiling substructure according to the invention, latching takes place by means of the above-described connectors between two transverse beams and the main beam. In the case of the metallic ceiling substructure according to the invention, it is then also provided, as is already known from the prior art, that the transverse beams may in turn be latched to one another. In this case, then also have the cross member in the web area on the opening described above. A latching then takes place with two other cross members with the connectors described above. By such a system can then be built a grid, as it has already prevailed as known in the prior art. In such grids is essential that the ceiling panels manufactured by the industry, which have a standard size, can be hung in the appropriate grid. For this purpose, according to the invention, the main carrier 3 to 4 m long, preferably 3.6 m and 3.75 m, and the cross member has a length of 0.5 m to 2.0 m, preferably 0.6 m to 0.625 m and 1.2 m and 1.25 m, respectively.

Die erfindungsgemäße metallische Deckenunterkonstruktion zeichnet sich noch weiterhin dadurch aus, dass die Verbindung der Querträger mit dem Hauptträger bzw. die Verbindung zweier Querträger mit einem weiteren Querträger durch die im Stegbereich angeordnete Öffnung so ausgebildet sein kann, dass Metallträger über Stoß an den Kreuzungspunkten miteinander verbunden sind. In diesem Fall stößt somit das stirnseitige Ende des Flansches der Querträger an die Längskante des Flansches an. Dadurch wird ein in Richtung Raumseite bündiger Übergang erreicht.The metallic ceiling substructure according to the invention is further distinguished by the fact that the connection of the cross members to the main carrier or the connection of two cross members with another cross member through the arranged in the web portion opening can be formed so that metal carriers are connected to each other via impact at the intersection points , In this case, thus abuts the front end of the flange of the cross member to the longitudinal edge of the flange. This achieves a flush transition towards the room side.

Die erfindungsgemäße Deckenunterkonstruktion kann aber auch so ausgestaltet sein, dass die stirnseitigen Enden der Querträger eine Kröpfung aufweisen, so dass diese Kröpfung dann über den Flansch des Hauptträgers bzw. auch des Querträgers greifen, so dass dann ein sicherer Halt gewährleistet wird.However, the ceiling substructure according to the invention can also be designed so that the front ends of the cross member have a crank, so that this offset then engage over the flange of the main carrier or the cross member, so that then a secure grip is ensured.

Eine weitere besonders bevorzugte Ausführungsform schlägt nun vor, dass zur sicheren Verbindung der Querträger mit dem Hauptträger bzw. der Querträger untereinander jeweils an den stirnseitigen Enden der Querträger ein aus dem Material des Querträgers herausgearbeiteter Vorsprung vorhanden ist. Dieser Vorsprung greift dann im verrasteten Zustand über den Flansch des Hauptträgers bzw. des Querträgers und sorgt für eine zusätzliche Stabilisierung.Another particularly preferred embodiment now proposes that for safe connection of the cross member with the main carrier or the cross member with each other at the front ends of the cross member a herausgearbeiteter from the material of the cross member projection is present. This projection then engages in the locked state on the flange of the main carrier or the cross member and provides additional stabilization.

Der Vorteil dieser Lösung besteht nun darin, dass dieser Vorsprung bei der Herstellung des Querträgers mit aus dem Material des Querträgers in einem Arbeitsgang herausgearbeitet werden kann. Der Vorsprung, der aus dem Steg des Querträgers herausragt, ist somit integraler Bestandteil des Querträgers selbst. Die Länge und Dimensionierung des Vorsprungs des Querträgers ist so abgestimmt, dass ein sicheres Übergreifen des Vorsprungs über die Oberseite des Flansches der Hauptträger bzw. eines weiteren Querträgers erreicht wird. Es hat sich gezeigt, dass besonders diese Variante bevorzugt ist, da sie zum einen kostengünstig herzustellen ist und zudem ein sicheres und stabiles Verrasten ermöglicht. Auch hat diese Lösung mit dem Vorsprung den Vorteil, dass beim Lösen der Rastverbindung kein Verklemmen stattfindet, so dass sich die Rastverbindung in einfacher Weise wieder löst.The advantage of this solution consists in the fact that this projection can be worked out in the manufacture of the cross member with the material of the cross member in one operation. The projection, which protrudes from the web of the cross member is thus an integral part of the cross member itself. The length and dimensioning of the projection of the cross member is adjusted so that a secure overlap of the projection on the top of the flange of the main carrier or another cross member achieved becomes. It has been found that especially this variant is preferred because it is inexpensive to manufacture on the one hand and also allows a secure and stable locking. Also, this solution has the advantage that there is no jamming when releasing the locking connection, so that the locking connection in a simple manner dissolves again.

Bei der erfindungsgemäßen Konstruktion ist der T-Träger bevorzugt aus einem Doppelblech gebildet. Die Herstellung eines derartigen T-Trägers erfolgt somit aus einem planen Blech, das durch bestimmte Umformvorgänge so umgeformt wird, dass ein T mit einer Steglänge bevorzugt im Bereich von 20 bis 80 mm und einer Flanschbreite von 10 bis 70 mm entsteht. Wie bisher bereits im Stand der Technik schon bekannt, ist es auch bei der erfindungsgemäßen Deckenunterkonstruktion bevorzugt, dass das stegseitige Ende des T-Trägers ein Hohlprofil, bevorzugt in Rechteckform, aufweist. Auch kann bei der erfindungsgemäßen Deckenunterkonstruktion vorgesehen sein, dass das Doppelblech am flanschseitigen Ende des T-Trägers über ein zusätzliches metallisches Abschlussblech verbunden ist. Dieses metallische Abschlussblech, das dann raumseitig optisch zur Wirkung kommt, kann entsprechend der gewünschten Gestaltung ausgebildet sein. Neben den optischen Effekten hat dieses metallische Abschlussblech auch noch den Vorteil, dass es für eine zusätzliche Stabilisierung des flanschseitigen Endes des T-Profils sorgt.In the construction according to the invention, the T-beam is preferably formed from a double sheet. The production of such a T-beam thus takes place from a flat sheet, which is formed by certain forming operations so that a T with a web length preferably in the range of 20 to 80 mm and a flange width of 10 to 70 mm is formed. As already known in the prior art, it is also preferred in the ceiling substructure according to the invention that the web-side end of the T-beam has a hollow profile, preferably in a rectangular shape. It can also be provided in the ceiling substructure according to the invention that the double sheet is connected to the flange-side end of the T-beam via an additional metallic end plate. This metallic end plate, which then visually comes into effect on the room side, can be designed according to the desired design. In addition to the optical effects, this metallic end plate also has the advantage that it provides additional stabilization of the flange end of the T-profile.

Der erfindungsgemäß eingesetzte T-Träger für die Hauptträger und die Querträger kann dabei im Stegbereich noch dadurch weiter gebildet werden, dass bevorzugt über die gesamte Länge des Stegbereiches mindestens ein linienförmiges Verstärkungsprofil vorhanden ist. Dieses Verstärkungsprofil kann z.B. in Form eines Rechtecks in das Metall eingeprägt sein. Die Erfindung umfasst dabei auch Ausführungsformen, bei denen mehr als ein Verstärkungsprofil, z.B. zwei oder drei Verstärkungsprofile, in Parallelform im Stegbereich eingearbeitet sind.The T-beam used according to the invention for the main beams and the cross beams can be further formed in the web area by providing at least one line-shaped reinforcing profile over the entire length of the web area. This reinforcing profile may for example be embossed in the form of a rectangle in the metal. The invention also encompasses embodiments in which more than one reinforcing profile, for example two or three reinforcing profiles, are incorporated in the web area in parallel form.

Zur weiteren Verbesserung der Steifigkeit des Trägersystems können zusätzlich noch im Stegbereich der Hauptträger und Querträger im Bereich des flanschseitigen Endes Verstärkungsrippen eingepresst sein. Diese Verstärkungsrippen können punktuell oder in Form von kurzen Linien im Stegbereich im Bereich des flanschseitigen Endes eingearbeitet sein. Diese Verstärkungsrippen sind gewöhnlicherweise ebenfalls in Linienform ausgebildet und verlaufen parallel zum Flansch. Bevorzugt werden dabei die Verstärkungsrippen durch einen zweistufigen Prozess in den Steg eingebracht. Im ersten Prozessschritt wird dabei eine Lasche aus dem Material freigeschnitten. Im zweiten Prozessschritt erfolgt dann durch einen Stempel ein Verpressen, so dass ein Fließen des Materials der Lasche erfolgt. Durch dieses Verpressen wird dann sichergestellt, dass die Lasche nicht wieder zurück in die Aussparung gedrückt werden kann. Erfindungsgemäß ist eine derartige Ausbildung der Verstärkungsrippen gemäß der vorliegenden Erfindung bevorzugt, da insbesondere mit einer derartigen Ausbildung der Verstärkungsrippen eine hohe Verbesserung der Verwindungssteifigkeit erreicht werden kann.In order to further improve the rigidity of the carrier system, reinforcing ribs may additionally be pressed in the web region of the main carrier and cross member in the region of the flange-side end. These reinforcing ribs can be incorporated selectively or in the form of short lines in the web area in the region of the flange-side end. These reinforcing ribs are usually also formed in a line shape and parallel to the flange. Preferably, the reinforcing ribs are introduced by a two-stage process in the web. In the first process step, a tab is cut free from the material. In the second process step is then carried out by a stamp pressing, so that a flow of the material of the tab takes place. By this pressing is then ensured that the tab can not be pushed back into the recess. According to the invention, such a configuration of the reinforcing ribs according to the present invention is preferred, since a high improvement of the torsional stiffness can be achieved, in particular, with such a configuration of the reinforcing ribs.

Mit dem vorstehend beschriebenen Verfahren zum Einpressen der Verstärkungsrippen wird somit eine Einpressung von einer Seite der Seitenfläche des Stegbereichs in Richtung der anderen erzeugt. Es hat sich nun herausgestellt, dass es weiterhin bevorzugt ist, wenn diese Verstärkungsrippen nicht nur von einer Seite in Richtung der anderen Seite der Seitenfläche des Stegbereiches eingepresst werden, sondern wenn hier ein Teil der Verstärkungsrippen von der gegenüber liegenden Seite aus eingepresst wird. Bevorzugt ist es dabei, wenn die Verstärkungsrippen die bevorzugt in Linienform angeordnet sind, abwechselnd jeweils von einer Seite in Richtung der anderen eingepresst werden. Es hat sich gezeigt, dass insbesondere durch diese Ausführungsform eine nochmalige Verbesserung der Versteifung und der Verwindungssicherheit der Metallträger, die eine Länge von 2 m erreichen können, realisiert wird. Diese Ausführungsform kann dann selbstverständlich kombiniert werden mit der weiteren Möglichkeit, dass zusätzlich noch eine linienförmige Verstärkung wie vorstehend beschrieben vorhanden ist. Weiterhin ist eine Ausführungsform bevorzugt, bei der am flanschseitigen Ende jeweils abwechselnd die Verstärkungsrippen von einer Richtung in die andere eingepresst worden sind, und dass dann zusätzlich parallel hierzu am stegseitigen Ende in Richtung des Hohlprofils weitere Verstärkungsrippen eingepresst sind, die wiederum abwechselnd von einer Richtung in die andere eingearbeitet sind. Die am stegseitigen Ende angeordneten Verstärkungsrippen können dabei einen größeren Abstand zueinander aufweisen.Thus, with the above-described method of pressing in the reinforcing ribs, a press-fitting is generated from one side of the side surface of the land portion toward the other. It has now been found that it is further preferred if these reinforcing ribs are pressed not only from one side towards the other side of the side surface of the web region, but when a part of the reinforcing ribs is pressed in from the opposite side. It is preferred, when the reinforcing ribs are preferably arranged in line form, alternately each be pressed in from one side towards the other. It has been found that, in particular, by this embodiment, a further improvement in the stiffening and torsional security of the metal support, which can reach a length of 2 m, is realized. Of course, this embodiment can then be combined with the further possibility that there is additionally a linear reinforcement as described above. Furthermore, an embodiment is preferred in which the reinforcing ribs have been alternately pressed from one direction into the other at the flange end, and that then further reinforcing ribs are additionally pressed parallel thereto at the web-side end in the direction of the hollow profile, which in turn alternately from one direction the other are incorporated. The arranged at the web-side end reinforcing ribs may have a greater distance from each other.

Die Erfindung umfasst selbstverständlich auch Ausführungsformen, bei denen z.B. zwei Verstärkungsrippen in Linienform parallel zum Flansch angeordnet sind und zusätzlich dann auch noch die wie vorstehend beschriebenen Verstärkungsprofile in Linienform vorhanden sind.Of course, the invention also includes embodiments in which e.g. two reinforcing ribs are arranged in line parallel to the flange and in addition then also the reinforcing profiles in line form as described above are present.

Zur Verbindung der Hauptträger untereinander ist es bei der Erfindung, wie auch im Stand der Technik schon bekannt, vorgesehen, dass dies über sog. Bajonett-Verschlüsse erfolgt. Die Verbindung der Hauptträger untereinander erfolgt somit anders als bei denjenigen an den zuvor genannten Kreuzungspunkten, d.h. an den Punkten, an denen das Raster durch Hauptträger und zwei Querträger bzw. aus einem Querträger und zwei Hauptträgern gebildet ist. Diese Kreuzungspunkte sind ausschließlich wie vorstehend beschrieben mittels der speziellen Konnektoren realisiert.To connect the main carrier with each other, it is provided in the invention, as already known in the prior art, that this is done via so-called. Bayonet closures. The connection of the main carrier to each other thus takes place differently than in those at the aforementioned crossing points, ie at the points where the grid by main carrier and two cross members or from a cross member and two main carriers is formed. These crossing points are realized exclusively as described above by means of the special connectors.

Das Material der metallischen Träger ist ein Stahlfeinblech aus einem kaltgewalzten Band. Die Stahlsorten umfassen integrierte C-Stähle mit Kohlenstoff-Masseanteilen bis zu 1 %, ein bevorzugtes Stahlfeinblech ist DX 51 Z 100.The material of the metallic carrier is a steel sheet of cold rolled strip. The steel grades include integrated C-steels with carbon mass fractions up to 1%, a preferred steel sheet is DX 51 Z 100.

Das Material für die Konnektoren ist ein Edelstahl, wie z.B. Chrom-Nickel-legierte Stähle, wie z.B. X10CrNi18-8 (AISI 301).The material for the connectors is a stainless steel, e.g. Chromium-nickel alloyed steels, such as e.g. X10CrNi18-8 (AISI 301).

Bei der Erfindung ist besonders hervorzuheben, dass durch die Materialwahl Edelstahl in Kombination mit der Omega-Form eine herausragende mechanische Stabilität erreicht wird.In the invention, it should be emphasized that the choice of material stainless steel in combination with the omega shape outstanding mechanical stability is achieved.

Die Erfindung umfasst dabei selbstverständlich Ausführungsformen, bei denen nur Verstärkungsrippen in Linienform angeordnet sind oder dass nur Verstärkungsprofile in Linienform vorgesehen sind. FIG. 1 shows in plan view the formation of the opening 1, as provided according to the invention in the metal supports, ie both in the main carrier and in the cross member. The opening 1 is formed in a rectangular shape and has two projections 2, 3 on the two short sides and two projections 4 and 5 on the longitudinal sides. The projections are be worked out of the material of the double sheet metal carrier or they can be applied separately in one operation. These reinforcing ribs, which are likewise likewise arranged linearly in the vicinity of the flange 32 close to the flange, again increase the rigidity, in order then to produce sufficient stability for the ceiling substructure when the corresponding ceiling elements are suspended. The invention includes, of course, embodiments in which only reinforcing ribs are arranged in line form or that only reinforcing profiles are provided in line form.

Wie aus dem Ausführungsbeispiel nach Figur 2 hervorgeht, weist der dort gezeigte Metallträger zusätzlich noch ein metallisches Abschlussblech 10 auf, das über die Enden des Flansches 31 der Metallträger gefalzt ist. Mittels dieses Abschlussbleches kann eine gewünschte optische Wirkung raumseitig hergestellt werden. Weiterhin sorgt das Abschlussblech auch für einen bündigen Abschluss raumseitig.As in the embodiment according to FIG. 2 shows, the metal support shown there additionally has a metallic end plate 10 which is folded over the ends of the flange 31 of the metal support. By means of this end plate, a desired optical effect can be produced on the room side. Furthermore, the end plate also ensures a flush conclusion room side.

Figur 3 zeigt nun ausschnittsweise die Ausbildung eines erfindungsgemäßen Haken-Konnektors 11 und dessen Befestigung an einem Querträger 12. Der Konnektor 11, wie aus Figur 3 zu entnehmen ist, ist über zwei Verpressungen 13, 14 am stirnseitigen Ende des Querträgers 12 befestigt. Der Konnektor 11 zeichnet sich dadurch aus, dass er an seinem freien Ende einen Haken 15 besitzt. Wie nachfolgend bei der Figur 4 näher erläutert, dient dieser Haken 15 zur Verrastung mit dem Hauptträger bzw. Querträger. Die Ausführungsform des Konnektors, wie er Figur 3 gezeigt ist, besitzt zudem zwei Öffnungen 16 und 17. Wie aus der Figur hervorgeht, ist dabei die erste Öffnung 17, d.h. diejenige, die dem stirnseitigen Ende des Steges zugewandt ist, in Rechteckform ausgebildet und besitzt nach außen aufgewölbte Längsseiten. Die zweite Öffnung 16 ist nun plan ausgebildet und so gestaltet, dass beim Ineinandergreifen der Konnektoren 11 an den Kreuzungspunkten die Auswölbung des anderen Konnektors 17 in die Öffnung 16 eingreifen kann. Dadurch wird eine sichere und unverrückbare Stabilisierung der beiden Querträger zueinander erreicht. Der Konnektor 11, so wie er in Figur 3 dargestellt ist, zeichnet sich weiterhin noch dadurch aus, dass er zwei Abkantungen 18, 19 aufweist, so dass eine Omega-Form entsteht. Diese Abkantungen 18, 19 sind in ihrer Ausformung so ausgebildet, dass sie mit den Vorsprüngen 4 und 5, wie in Figur 1 gezeigt, zusammen wirken. FIG. 3 shows a detail of the formation of a hook connector 11 according to the invention and its attachment to a cross member 12. The connector 11, as shown FIG. 3 can be seen, is attached via two pressings 13, 14 at the front end of the cross member 12. The connector 11 is characterized in that it has a hook 15 at its free end. As below in the FIG. 4 explained in more detail, this hook 15 is used for locking with the main beam or cross member. The embodiment of the connector, as he FIG. 3 is shown also has two openings 16 and 17. As is apparent from the figure, is the first opening 17, ie the one which faces the front end of the web, formed in a rectangular shape and has outwardly bulging longitudinal sides. The second opening 16 is now flat and designed so that when interlocking the connectors 11 at the crossing points, the bulge of the other connector 17 can engage in the opening 16. As a result, a secure and immovable stabilization of the two cross members is achieved to each other. The connector 11, as in FIG. 3 is still characterized by the fact that it has two folds 18, 19, so that an omega shape is formed. These bends 18, 19 are formed in their shape, that they with the projections 4 and 5, as in FIG. 1 shown, work together.

Ein weiteres wesentliches Element des erfindungsgemäßen Haken-Konnektors ist es, dass dieser im abgekanteten Bereich, und zwar auf der Seite, die der Flanschseite abgewandt ist, eine bogenförmige Vertiefung 41 mit einer Nase 40 aufweist. Durch diese Ausbildung in Bogenform 41 mit einer Nase 40 wird gewährleistet, dass auch der Haken-Konnektor im verrasteten Zustand in der Öffnung an der von der Flanschseite abgewandten oberen kurzen Seite der rechteckförmigen Öffnung anschlägt, durch Verdrehen der Verrastverbindung dieser Anschlag gelöst werden und der Querträger über die bogenförmige Vertiefung wieder herausgezogen werden kann.Another essential element of the hook connector according to the invention is that this has an arcuate recess 41 with a nose 40 in the folded portion, on the side facing away from the flange side. By this training in the form of an arc 41 with a nose 40 ensures that the hook connector in the locked state in the opening abuts on the side facing away from the flange upper short side of the rectangular opening to be solved by turning the Verrastverbindung this stop and the cross member can be pulled out over the arcuate recess again.

Die in Figur 3 dargestellte Ausführungsform zeichnet sich noch weiterhin dadurch aus, dass der Querträger 12 mit einem Vorsprung 20 versehen ist. Dieser Vorsprung 20, der integraler Bestandteil des Querträgers 12 ist, ist aus demselben Material wie der Querträger 12 herausgearbeitet und dient zur Stabilisierung der Wirkverbindung der beiden zu verbindenden Querträger 12 mit einem Hauptträger bzw. mit einem anderen Querträger. Die Ausbildung und Form des Vorsprunges 20 ist dabei so gewählt, dass er im verrasteten Zustand über den Flansch des Hauptträgers bzw. des Querträgers greift und somit zu einer Stabilisierung beiträgt (siehe u.a. Figur 4).In the FIG. 3 illustrated embodiment is still characterized by the fact that the cross member 12 is provided with a projection 20. This projection 20, which is an integral part of the cross member 12 is machined out of the same material as the cross member 12 and serves to stabilize the Operative connection of the two transverse beams 12 to be connected to a main beam or to another cross beam. The design and shape of the projection 20 is chosen so that it engages in the locked state on the flange of the main carrier or the cross member and thus contributes to a stabilization (see, inter alia FIG. 4 ).

Die Ausführungsform nach Figur 3 zeigt gleichfalls noch die im Querträger 12 eingebrachten Verstärkungsrippen 8 in Linienform.The embodiment according to FIG. 3 also shows the introduced in the cross member 12 reinforcing ribs 8 in line form.

Figur 4 zeigt nun die erfindungsgemäße Ausbildung eines Klick-Konnektors. Der Klick-Konnektor nach der Erfindung besitzt ebenfalls, was als erfindungswesentlich angesehen wird, zwei Abkantungen 18, 19, so dass auch hier wiederrum eine Omega-Form entsteht. Der Klick-Konnektor nach der Erfindung besitzt dann, wie an und für sich aus dem Stand der Technik bekannt ist, ein federndes Element 50. Die Ausbildung dieses federnden Elementes 50 ist an und für sich bei vergleichbaren Klick-Konnektoren im Stand der Technik bekannt. FIG. 4 now shows the inventive design of a click connector. The click-connector according to the invention also has, what is considered essential to the invention, two folds 18, 19, so that in turn here an omega-shape is formed. The click connector according to the invention then has, as is well known in the art, a resilient element 50. The formation of this resilient element 50 is in and of itself known in comparable click connectors in the prior art.

In Figur 5 ist nun in zwei verschiedenen Schnitten a)und b) dargestellt, wie die beiden Querträger 12 über die Haken-Konnektoren und dem Hauptträger 21 verrastet sind.In FIG. 5 is now shown in two different sections a) and b), as the two cross members 12 are latched on the hook connectors and the main carrier 21.

Im Schnitt in der Figur 5a ist im linken Teil ausschnittsweise der Querträger 12 mit einem Haken-Konnektor 11 dargestellt, wie er vorstehend in der Figur 3 ausführlich beschrieben worden ist. Ein identischer Querträger 12 mit einem identischen Konnektor 11 ist im rechten Teil der Figur 5a dargestellt. Der Hauptträger 21, der nun hier nur im Schnitt zu sehen ist, ist analog wie in Figur 2 aufgebaut und besteht aus einem Steg mit einer rechteckförmigen Verstärkung 9 und einem Flansch. Die Öffnung ist mit 1 bezeichnet. Wie nun aus dem Schnitt in Figur 5a hervorgeht, greift der Haken 15 durch die Öffnung 1 hindurch. Die beiden Konnektoren 11 untereinander sind dann über die Öffnungen 16 und 17 miteinander verrastet. Dadurch, dass die Öffnung 17 eine Auswölbung nach außen aufweist, kann diese Aufwölbung der Öffnung 17 des einen Konnektors 11 in die plane Öffnung 16 des anderen Konnektors 11 eingreifen, um so eine sichere Verrastung zu bewerkstelligen.On average in the FIG. 5a is partially shown in the left part of the cross member 12 with a hook connector 11, as described above in the FIG. 3 has been described in detail. An identical cross member 12 with an identical connector 11 is in the right part of FIG. 5a shown. The main carrier 21, which now only seen in section here is, is analogous to in FIG. 2 constructed and consists of a web with a rectangular reinforcement 9 and a flange. The opening is designated 1. Like now from the cut in FIG. 5a shows, the hook 15 engages through the opening 1 therethrough. The two connectors 11 are then locked together via the openings 16 and 17 with each other. Characterized in that the opening 17 has a bulge to the outside, this bulge of the opening 17 of a connector 11 can engage in the planar opening 16 of the other connector 11, so as to accomplish a secure locking.

In Figur 5b ist die Verrastung in der Draufsicht dargestellt. Der Hauptträger 21 ist dabei, wie vorstehend bei Figur 5a beschrieben, mit den beiden Querträgern 12 und den identischen Konnektoren 11 verrastet. Die Verrastung wird über die Konnektoren 11 der jeweiligen Querträger 12, die mittels Nieten 13, 14 am stirnseitigen Ende der Querträger befestigt sind, erreicht (Kreuzungspunkt).In FIG. 5b the latch is shown in plan view. The main carrier 21 is, as in the above FIG. 5a described, with the two cross beams 12 and the identical connectors 11 locked. The locking is achieved via the connectors 11 of the respective cross members 12, which are fastened by means of rivets 13, 14 at the front end of the cross member (crossing point).

In Figur 6 ist nun in einem dritten Schnitt in vergrößerter Darstellung die Verrastung der beiden Haken-Konnektoren in der Öffnung 1 dargestellt. Figur 6 zeigt dabei das Zusammenwirken der Öffnung 1 mit den speziell ausgebildeten Konnektoren 11. In Figur 6 ist die Omega-Form (gestrichelt) der Konnektoren 11 zu sehen.In FIG. 6 is now shown in a third section in an enlarged view the locking of the two hook connectors in the opening 1. FIG. 6 shows the interaction of the opening 1 with the specially designed connectors 11. In FIG. 6 is the omega shape (dashed) of the connectors 11 to see.

Wie in Figur 6 verdeutlicht wird, dienen die Vorsprünge 2, 3, 4 und 5 zur Führung des Konnektors 11. Der Konnektor 11 weist Abkantungen 18, 19 auf, die so ausgebildet sind, dass sie die Vorsprünge 2, 3, 4 und 5 umgreifen. Dazu ist der Konnektor 11 mit Abkantungen 18, 19 versehen, die die genannten Längsseiten durchziehen, ausgebildet, wobei diese Abkantungen 18, 19 so ausgeformt sind, dass sie genau mit den Vorsprüngen 2, 3, 4 und 5 zusammenwirken und so einen sicheren Halt der Verrastverbindung gewährleisten.As in FIG. 6 is illustrated, the projections 2, 3, 4 and 5 serve to guide the connector 11. The connector 11 has folds 18, 19 which are formed so that they engage around the projections 2, 3, 4 and 5. For this purpose, the connector 11 is provided with folds 18, 19, the said longitudinal sides pulled through, formed, these folds 18, 19 are formed so that they interact exactly with the projections 2, 3, 4 and 5, thus ensuring a secure fit of Verrastverbindung.

Letztlich zeigt Figur 7 den Hauptträger 21 mit der Öffnung 1 und einem Bajonett-Verschluss 30. Zur Verbindung der Hauptträger untereinander wird somit erfindungsgemäß nicht ein Konnektor wie vorstehend beschrieben vorgeschlagen, sondern diese Verbindung wird mit an und für sich aus dem Stand der Technik bekannten Bajonett-Verschlüssen gewährleistet.Ultimately shows FIG. 7 The main carrier 21 with the opening 1 and a bayonet closure 30. Thus, according to the invention, a connector as described above is not proposed for connecting the main carriers to one another, but this connection is ensured with bayonet closures known per se from the prior art.

Figur 8 zeigt nun in drei verschiedenen Ansichten den bereits bei Figur 3 näher beschriebenen Haken-Konnektor 11. In der Figur 8a ist der Haken-Konnektor 11 in der Draufsicht dargestellt und entspricht vollständig dem Haken-Konnektor, wie er in Figur 3 bereits im Detail beschrieben worden ist. In Figur 8b ist nun im Schnitt der Haken-Konnektor 11 dargestellt. Wie aus dem Querschnitt b) hervorgeht, besitzt der Haken-Konnektor 11 eine Omega-Form mit zwei Abkantungen 18 und 19. Letztlich zeigt Figur 8 dann noch den Haken-Konnektor 11 in der Seitenansicht. FIG. 8 shows now in three different views already at FIG. 3 closer described hook connector 11.

Die obige Ausführungsform bringt den Vorteil mit sich, dass sich noch ein leichteres und eindeutigeres Einrasten und Lösen bei gleichzei tig sicherem Halt der Rastverbindung ergibt.The above embodiment has the advantage that even easier and clearer locking and releasing at the same time tig sure Hold the locking connection results.

Es wird nun eine weitere Ausführungsform der Metallträger, d.h. sowohl der Hauptträger als auch der Querträger beschrieben. Im Wesentlichen entspricht die Ausführungsform derjenigen, wie sie bereits ausführlich bei Figur 2 beschrieben worden ist. Unterschiedlich zu der Ausführungsform nach Figur 2 ist nun, dass neben den Verstärkungsrippen 8, die im flanschnahen Bereich ausgebildet sind, und dem linienförmigen Verstärkungsprofil, noch zusätzlich weitere Verstärkungsrippen vorgesehen sind. Diese zusätzlichen Verstärkungsrippen sind ebenfalls wie die Verstärkungsrippen 8 in den metallischen Träger eingearbeitet, z.B. auch eingepresst, weisen jedoch bevorzugt einen größeren Abstand zueinander auf wie die Verstärkungsrippen 8 im flanschnahen Bereich. Die Erfindung umfasst dabei selbstverständlich auch Ausführungsformen, bei denen mehr zusätzliche Verstärkungsrippen eingebracht sind. Wesentlich ist jedoch, dass diese zusätzlichen Verstärkungsrippen im Stegbereich zwischen der linienförmigen Verstärkung 7 und dem rechteckigen Hohlprofil 9 ausgebildet sind.There will now be described another embodiment of the metal carrier, ie both the main carrier and the cross member. In essence, the embodiment corresponds to those already detailed in FIG. 2 has been described. Different from the embodiment according to FIG. 2 is now that in addition to the reinforcing ribs 8, which are formed in the region near the flange, and the linear reinforcing profile, further reinforcing ribs are additionally provided. These additional reinforcing ribs are also incorporated as the reinforcing ribs 8 in the metallic carrier, for example, also pressed, but preferably have a greater distance from each other as the reinforcing ribs 8 in the vicinity of the flange. Of course, the invention also includes embodiments in which more additional reinforcing ribs are introduced. It is essential, however, that these additional reinforcing ribs are formed in the web region between the linear reinforcement 7 and the rectangular hollow profile 9.

Es werden nun Ausführungsformen des Metallträgers beschrieben, bei denen zusätzlich Verstärkungsrippen jeweils abwechselnd von einer Seite in Richtung der anderen eingebracht sind. Bei einer Ausführungsform sind linienförmig Verstärkungsrippen am flanschseitigen Ende eingebracht. Bei dieser Ausführungsform sind jeweils die Verstärkungsrippen abwechselnd von einer Seite in Richtung der anderen eingearbeitet worden.Embodiments of the metal carrier will now be described, in which additionally reinforcing ribs are alternately introduced from one side in the direction of the other. In one embodiment, reinforcing ribs are linearly introduced at the flange end. In this embodiment, each of the reinforcing ribs has been alternately worked from one side toward the other.

Bei dieser Ausführungsform sind somit zum einen parallel zum Flansch in Linienform in gleichmäßigen Abständen Verstärkungsrippen jeweils abwechselnd von einer Seite in Richtung der anderen eingepresst worden und weiterhin parallel zum stegseitigen Ende in der Nähe des Hohlprofils 9 wiederum abwechselnd Verstärkungsrippen eingepresst, jedoch sind die in Richtung des stegseitigen Endes angeordneten Verstärkungsrippen in einem größeren Abstand vorgesehen. Es hat sich gezeigt, dass insbesondere diese Ausführungsform eine ausgezeichnete Verwindungssicherheit und Stabilität des Metallträgers realisiert.In this embodiment, parallel to the flange in line shape at regular intervals reinforcing ribs have been alternately pressed in each case from one side in the direction of the other and continue parallel to the web-side end in the vicinity of the hollow section 9 alternately pressed reinforcing ribs, but are in the direction of web-side end arranged reinforcing ribs provided at a greater distance. It has been found that, in particular, this embodiment realizes an excellent torsional security and stability of the metal carrier.

Bei einer anderen Ausführungsform sind dabei im Metallträger 21 nur abwechselnd am flanschseitigen Ende des Steges 32 Verstärkungsrippen jeweils abwechselnd von einer Richtung in die andere eingebracht worden.In another embodiment, reinforcing ribs 32 are alternately introduced alternately from one direction to the other in the metal carrier 21 only alternately at the flange-side end of the web.
