Description

Die vorliegende Erfindung betrifft einen Stabknoten zum Verbinden mehrerer Stäbe einer Tragkonstruktion zur Abstützung einer Verglasung, wobei die Endbereiche der Stäbe in dem Stabknoten zwischen zwei miteinander verschraubten Abdeckplatten gehalten sind und die Stäbe mit ihren Endbereichen über jeweils zumindest einen Stirnflächenbereich drückend aneinanderliegen.The present invention relates to a rod knot Connecting several rods of a supporting structure for Supporting a glazing, the end regions of the Bars in the bar knot between two with each other screwed cover plates are held and the rods with their end regions over at least one each Press the end face area together.

Die Verglasung kann als Glaswand oder Glasdach ausgeführt sein. Die Glaswand bzw. das Glasdach setzen sich aus einer Vielzahl von einzelnen Glasscheiben zusammen, die in einem Abstand zueinander auf der Tragkonstruktion befestigt sind. Unter jedem Rand der Glasscheiben verlaufen stets Stäbe der Tragkonstruktion.The glazing can be designed as a glass wall or glass roof be. The glass wall or the glass roof consist of one Variety of individual panes of glass put together in one Distance to each other are attached to the support structure. Rods always run under each edge of the glass panes Supporting structure.

Ein derartiger Stabknoten ist beispielsweise aus der WO 96/25568 bekannt. Bei dem dort offenbarten Stabknoten werden innerhalb des Stabknotens auftretende Druckkräfte über die Flächenkontakte zwischen den aneinanderstoßenden Stäben übertragen. Zugkräfte dagegen werden über die den Stoßbereich beidseitig überdeckenden, miteinander verschraubten Abdeckplatten übertragen. Biegekräfte werden in Druck- und Zugkräften zerlegt und in der oben genannten Weise zwischen den Stäben übertragen.Such a rod node is, for example, from the WO 96/25568 known. At the staff node disclosed there compressive forces occurring within the member node over the surface contacts between the abutting ones Beams transferred. Tractive forces, however, are over the Joint area overlapping on both sides, with each other screwed cover plates transferred. Bending forces broken down into compressive and tensile forces and in the above Transfer way between bars.

Wenn bei dem vorbekannten Stabknoten die Verbindungsschrauben durch die beiden Abdeckplatten und durch die dazwischenliegenden Endbereiche der Stäbe verlaufen, lasten insbesondere bei der Übertragung von Zugkräften nahezu die gesamten Kräfte auf den Verbindungsschrauben. Die Übertragung der Zugkräfte zwischen den Stäben im Bereich der Stabknoten erfolgt mittelbar über die Verbindungsschrauben. Die Größe der übertragbaren Kräfte und damit auch die durch die Tragkonstruktion überspannbaren Weiten werden also im wesentlichen durch die Stabilität der Verbindungsschrauben begrenzt.If at the previously known staff node Connection screws through the two cover plates and through the intermediate end areas of the rods run, especially when transferring Tractive forces almost the entire forces on the Connecting screws. The transmission of tractive forces between the bars in the area of the bar nodes indirectly via the connecting screws. The size of the transferable forces and thus also by the Supporting structure spans widths are therefore in essentially due to the stability of the connecting screws limited.

Die Aufgabe der Erfindung besteht deshalb darin, einen Stabknoten der eingangs genannten Art dahingehend weiterzubilden, dass die Verbindungsschrauben bei der Übertragung von Kräften über den Stabknoten entlastet werden und dadurch wesentlich größere Kräfte über den Stabknoten zwischen den Stäben übertragen werden können.The object of the invention is therefore one Rod nodes of the type mentioned in this regard to further develop that the connecting screws at the Transfer of forces via the staff node relieved be and thus much larger forces over the Rod nodes between the rods can be transferred.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass die Wirkflächen zwischen den Abdeckplatten und den Endbereichen der Stäbe formschlüssig miteinander im Eingriff stehen.To achieve this object, the invention proposes that the effective areas between the cover plates and the End areas of the rods form-fitting with each other in the Stand by.

Als Wirkflächen werden nachfolgenden diejenigen Oberflächen der Abdeckplatten bzw. der Endbereiche der Stäbe verstanden, die sich gegenseitig berühren. Die Wirkflächen können beispielsweise jeweils mit einer Verzahnung versehen werden, wobei die Zähne einer ersten Wirkfläche in die Zahnzwischenräume einer die erste Wirkfläche berührenden zweiten Wirkfläche eingreifen, und umgekehrt die Zähne der zweiten Wirkfläche in die Zahnzwischenräume der ersten Wirkfläche eingreifen. The following surfaces are the effective surfaces the cover plates or the end areas of the rods understood that touch each other. The effective areas can, for example, each have a toothing be, the teeth of a first active surface in the Interdental spaces of a tooth touching the first active surface engage second effective area, and vice versa the teeth of the second effective area in the interdental spaces of the first Intervene effective area.

Dadurch, dass die Wirkflächen erfindungsgemäß über eine Formschlussverbindung miteinander verbunden sind, werden die Druck- und Zugkräfte im wesentlichen unmittelbar über die Abdeckplatten zwischen den Stäben übertragen. Folglich werden die Verbindungsschrauben von Druck- und Zugkräften entlastet. Dies erhöht die Tragfähigkeit des Stabknotens in erheblichem Maße. Dadurch können die durch die Tragkonstruktion überspannbaren Weiten erheblich vergrößert werden. Sollen die Spannweiten jedoch nicht vergrößert werden, können statt dessen die Verbindungsschrauben entsprechend schwächer dimensioniert werden. Dies kann beispielsweise durch den Einsatz eines preisgünstigeren Schraubenmaterials erfolgen, was zu vorteilhaften Kosteneinsparungen führt. Die Stärke der Verbindungsschrauben kann aber auch durch eine Verringerung der Abmessungen der Schrauben reduziert werden, wodurch vorteilhafterweise kleinbauendere Stabknoten realisiert werden können.The fact that the active surfaces according to the invention over a Form-fit connection are interconnected the compressive and tensile forces essentially directly above transfer the cover plates between the bars. Hence are the connecting screws of compressive and tensile forces relieved. This increases the load capacity of the bar knot in considerable measure. This allows the through the Supporting structure spans wide extended considerably become. However, the spans should not be enlarged the connecting screws can be used instead be dimensioned correspondingly weaker. This can for example by using a cheaper one Screw material done, which is beneficial Cost savings leads. The strength of the Connecting screws can also be reduced the dimensions of the screws can be reduced, whereby advantageously smaller rod nodes realized can be.

In einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass an den Wirkflächen der Abdeckplatten Vertiefungen und an den Wirkflächen der Endbereiche der Stäbe Vorsprünge ausgebildet sind, die in die Vertiefungen formschlüssig eingreifen. Dies ist eine einfache und zugleich sehr wirkungsvolle Ausgestaltungsform der Wirkflächen mit einer Formschlussverbindung zwischen den Abdeckplatten und den Endbereichen der Stäbe. Die Vertiefungen können beispielsweise als Öffnungen und die Vorsprünge als Stifte ausgebildet sein, die in die Öffnungen formschlüssig eingreifen.In an advantageous development of the invention suggested that on the active surfaces of the cover plates Depressions and on the active surfaces of the end regions of the Rods projections are formed in the recesses intervene positively. This is a simple one at the same time very effective design of the Active surfaces with a positive connection between the Cover plates and the end areas of the rods. The Wells can, for example, as openings and the Projections can be designed as pins which in the Intervene in openings.

Es hat sich als besonders vorteilhaft erwiesen, die Vertiefungen als in die Wirkflächen der Abdeckplatten eingelassene kreisringförmige Nuten und die Vorsprünge als von den Wirkflächen der Endbereiche der Stäbe vorspringende Ringabschnitte auszubilden, die in die Nuten formschlüssig eingreifen. Die Stäbe und die Abdeckplatten stehen nach dem Nut- und Federprinzip miteinander formschlüssig im Eingriff. Auf diese Weise können die Kräfte, die im Bereich des Stabknotens wirken, besonders großflächig von den Stäben auf die Abdeckplatten und umgekehrt übertragen werden. Dadurch werden die Verbindungsschrauben besonders stark entlastet.It has proven to be particularly advantageous that Indentations than in the active surfaces of the cover plates recessed circular grooves and the projections as protruding from the active surfaces of the end regions of the rods Form ring sections that fit into the grooves intervention. The rods and the cover plates are after the Tongue and groove principle with each other in a form-fitting manner Intervention. This allows the forces in the area of the staff knot, especially large areas of the Transfer rods to the cover plates and vice versa become. This makes the connecting screws special greatly relieved.

In einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass die Stäbe in ihren jeweiligen Endbereichen sich verjüngende Stirnflächenbereiche aufweisen, an denen die benachbarten Stäbe flächig und drückend aneinanderliegen. Über diese aneinanderstoßende Stirnflächenbereiche können die Druckkräfte von einem Stab gleichmäßig auf die benachbarten Stäbe übertragen werden. In an advantageous development of the invention suggested that the bars in their respective End areas tapered end face areas have, on which the adjacent rods are flat and press against each other. About this abutting Face areas can take the compressive forces from a rod be transferred evenly to the neighboring bars.

Um eine besonders geringe Bauhöhe des Stabknotens realisieren zu können, hat es sich als vorteilhaft erwiesen, eine oder beide Abdeckplatten in etwa parallel zu den Wirkflächen mehr oder weniger tief versenkt in den Endbereichen der Stäbe anzuordnen. Durch das vollständige Versenken der Abdeckplatte, die der Verglasung zugewandt ist, weist die Tragkonstruktion auch im Bereich der Stabknoten einen im wesentlichen ebenen Auflagerahmen für die Verglasung auf. Durch eine geringe Bauhöhe der Stabknoten fügen sich diese unauffällig in das Gesamtbild einer möglichst schlanken Tragkonstruktion ein.To a particularly low overall height of the rod node To be able to realize it has proven to be advantageous proven to be approximately parallel to one or both cover plates the effective areas more or less deeply sunk into the Arrange end areas of the rods. Through the full Countersinking the cover plate facing the glazing is, the supporting structure also in the area of Rod knot an essentially flat support frame for the glazing on. Due to a low height of the Bar knots blend into the overall picture unobtrusively the slimmest possible supporting structure.

In einer weiteren vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass die Verbindungsschrauben auf der der Verglasung zugewandten Seite in der Abdeckplatte versenkt angeordnet sind. Dadurch weist die Tragkonstruktion im Bereich der Stabknoten eine ebene Auflagefläche für die Verglasung auf.In a further advantageous development of the invention it is suggested that the connecting screws on the the side facing the glazing in the cover plate are sunk. As a result, the Supporting structure in the area of the bar knot one level Contact surface for the glazing.

Vorteilhafterweise sind die Abdeckplatten als kreisförmige Abdeckscheiben ausgebildet. Diese sind besonders einfach herzustellen und genügen unabhängig von der Anzahl der zwischen den miteinander verschraubten Abdeckplatten gehaltenen Stäbe immer den Symmetrieanforderungen. The cover plates are advantageously circular Cover plates formed. These are particularly simple manufacture and suffice regardless of the number of between the cover plates screwed together bars always meet the symmetry requirements.

In dem Stabknoten sind vorteilhafterweise vier oder sechs Stäbe miteinander verbunden. Bei vier Stäben pro Stabknoten ergeben sich viereckige, mit Glasscheiben der Verglasung zu überdeckende Flächen zwischen den Stabknoten. Die Tragkonstruktion kann, beispielsweise durch sechs Stäbe pro Stabknoten, auch so ausgebildet werden, dass die Stabknoten dreieckige mit Glasscheiben zu überdeckende Flächen einschließen.There are advantageously four or six in the rod node Rods connected together. With four members per member node result in quadrangular, with glass panes of the glazing overlapping areas between the staff nodes. The Support structure can, for example, by six bars per Rod knots, also be designed so that the rod knots triangular surfaces to be covered with glass panes lock in.

Entsprechend den jeweiligen Anforderungen liegen die Winkel zwischen benachbarten Stäben eines Stabknotens vorzugsweise im Bereich zwischen 0° und 180°. Bei einer derartig ausgebildeten Tragkonstruktion lassen sich die zu übertragenden Kräfte noch gut auf die jeweils angeschlossenen anderen Stäbe übertragen. Bei vier Stäben pro Stabknoten sind die Stäbe eines Stabknotens vorzugsweise in einem Winkel von etwa 90° zueinander angeordnet, bei sechs Stäben pro Stabknoten beträgt dieser Winkel etwa 60°.The angles are in accordance with the respective requirements preferably between adjacent bars of a bar node in the range between 0 ° and 180 °. With one like that trained support structure can be transmitting forces are still good on each connected other rods transferred. With four bars per staff node are the staffs of a staff node preferably at an angle of approximately 90 ° to one another arranged, with six members per member node this is Angle about 60 °.

2 shows a plan view of the rod node according to the invention from FIG. 1.

In den Fig. 1 und 2 ist ein erfindungsgemäßer Stabknoten in seiner Gesamtheit mit dem Bezugszeichen 1 bezeichnet. Der Stabknoten 1 dient zum Verbinden mehrerer Stäbe 2 bis 5 einer Tragkonstruktion zur Abstützung einer Verglasung (nicht dargestellt). Die Stäbe 2 bis 5 können als Vollmaterialrechteckprofile mit einer Breite von 40 mm und einer Höhe von 60 mm als unter Profilgrenze bis hin zu Rechteckhohlprofilen mit einer Breite von 60 mm, einer Höhe von 120 mm und einer Wandstärke von 12 mm ausgebildet sein. In dem hier dargestellten Ausführungsbeispiel werden Vollmaterialrechteckprofile verwendet. Der Stabknoten 1 weist eine obere kreisförmige Abdeckscheibe 6 und eine untere kreisförmige Abdeckscheibe 7 auf. Die Abdeckscheiben 6, 7 sind mittels Verbindungsschrauben 8 bis 11 miteinander verschraubt. Zwischen den miteinander verschraubten Abdeckscheiben 6, 7 sind die Endbereiche 2a bis 5a der Stäbe 2 bis 5 gehalten.1 and 2 is a rod node according to the invention in designated in its entirety with reference number 1. Of the Member node 1 is used to connect several members 2 to 5 a supporting structure for supporting glazing (not shown). Bars 2 to 5 can be used as Solid material rectangular profiles with a width of 40 mm and a height of 60 mm as below the profile limit up to Rectangular hollow profiles with a width of 60 mm, a height of 120 mm and a wall thickness of 12 mm. In the embodiment shown here Solid material rectangular profiles used. The staff node 1 has an upper circular cover plate 6 and one lower circular cover plate 7. The cover plates 6, 7 are connected to each other by means of connecting screws 8 to 11 screwed. Between the screwed together Cover plates 6, 7 are the end regions 2a to 5a of the Bars 2 to 5 held.

An den Oberflächen der Abdeckscheiben 6, 7, die die Endbereiche 2a bis 5a der Stäbe 2 bis 5 flächig berühren, den sog. Wirkflächen, sind kreisringförmige Nuten 6a, 7a eingelassen. An den Oberflächen der Endbereiche 2a bis 5a der Stäbe 2 bis 5, die die Abdeckscheiben flächig berühren, die ebenfalls als Wirkflächen bezeichnet werden, sind von den Wirkflächen vorspringende Ringabschnitte 2b bis 5b ausgebildet, die in die Nuten 6a, 7a formschlüssig eingreifen. Die Stäbe 2 bis 5 und die Abdeckscheiben stehen somit nach dem Nut- und Federprinzip miteinander formschlüssig im Eingriff. Auf diese Weise werden die Druck- und Zugkräfte, die im Bereich des Stabknotens 1 wirken, besonders großflächig von den Stäben 2 bis 5 unmittelbar auf die Abdeckscheiben 6, 7 und umgekehrt übertragen. Dies führt zu einer erheblichen Entlastung der Verbindungsschrauben 8 bis 11, wodurch wesentlich größere Kräfte über den Stabknoten 1 zwischen den Stäben 2 bis 5 übertragen werden können. Dadurch können durch die Tragkonstruktion wesentlich größere Weiten überspannt werden, als dies mit den Stabknoten nach dem Stand der Technik bisher möglich war.On the surfaces of the cover plates 6, 7, the Touch end areas 2a to 5a of rods 2 to 5 flat, the so-called active surfaces are circular grooves 6a, 7a let in. On the surfaces of the end regions 2a to 5a of rods 2 to 5, which touch the cover disks flatly, which are also referred to as active surfaces are from ring sections 2b to 5b projecting from the active surfaces formed in the grooves 6a, 7a intervention. The rods 2 to 5 and the cover plates are in place thus together according to the tongue and groove principle positive engagement. In this way, the Compression and tensile forces in the area of the rod node 1 act, especially over large areas of bars 2 to 5 directly on the cover plates 6, 7 and vice versa transfer. This leads to a considerable relief of the Connecting screws 8 to 11, which means much larger Forces via the rod node 1 between rods 2 to 5 can be transferred. This allows through the Supporting structure spans much larger widths when this is done with the staff nodes according to the state of the Technology was previously possible.

Die Stäbe 2 bis 5 weisen in ihren jeweiligen Endbereichen 2a bis 5a sich verjüngende Stirnflächenbereiche 2c bis 5c auf, an denen die benachbarten Stäbe 2 bis 5 flächig und drückend aneinanderliegen. Über diese aneinanderstoßende Stirnflächenbereiche 2c bis 5c können die Druckkräfte von einem Stab 2 bis 5 gleichmäßig auf die benachbarten Stäbe 2 bis 5 übertragen werden. The rods 2 to 5 have in their respective end regions 2a to 5a tapered end face areas 2c to 5c on which the adjacent rods 2 to 5 flat and press against each other. About this abutting End face areas 2c to 5c can the compressive forces of a rod 2 to 5 evenly on the neighboring rods 2 to 5 are transmitted.

Um eine besonders geringe Bauhöhe des Stabknotens realisieren zu können, sind die Abdeckscheiben 6, 7 in etwa parallel zu den Wirkflächen versenkt in den Endbereichen 2a bis 5a der Stäbe 2 bis 5 angeordnet. Die Verschraubungen 8 bis 11 sind auf der der Verglasung zugewandten Seite in der Abdeckscheibe 6 versenkt. Durch das Versenken der Abdeckscheibe 6 in den Endbereichen 2a bis 5a der Stäbe 2 bis 5 und das Versenken der Verschraubungen 8 bis 11 in der Abdeckscheibe 6 bildet die Tragkonstruktion auch im Bereich der Stabknoten 1 einen ebenflächigen Auflagerahmen für die Verglasung.To a particularly low overall height of the rod node To be able to realize the cover plates 6, 7 are approximately sunk parallel to the active surfaces in the end regions 2a to 5a of the rods 2 to 5 arranged. The screw connections 8 to 11 are on the side facing the glazing in the Cover plate 6 sunk. By sinking the Cover plate 6 in the end regions 2a to 5a of the rods 2 to 5 and the sinking of the screw connections 8 to 11 in the Cover plate 6 also forms the supporting structure in the area the rod node 1 a flat support frame for the Glazing.
