Abstract
Description
Die vorliegende Erfindung betrifft eine Tragkonstruktion zur Abstützung einer Verglasung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a supporting structure for supporting a glazing with the features of the preamble of claim 1.
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. The glass wall or the glass roof are composed of a plurality of individual glass panes, which are attached at a distance from each other on the support structure. Under each edge of the glass panes always run rods of the supporting structure.
Eine derartige Tragkonstruktion zur Abstützung einer Verglasung ist beispielsweise aus der WO-A-96 25 568 bekannt. Bei dem dort offenbarten Stabknoten werden die innerhalb des Stabknotens auftretenden 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 support structure for supporting a glazing is known for example from WO-A-96 25 568. In the rod node disclosed therein, the compressive forces occurring within the rod node are transmitted via the surface contacts between the abutting rods. Tensile forces, however, are transmitted over the cover area covering the joint area on both sides, screwed together cover plates. Bending forces are broken down into compressive and tensile forces and transmitted in the above manner between the 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. Außerdem kann der Knotenbereich von keiner Glasplatte überdeckt werden, da diese an den Schraubenköpfen oder Muttern anstoßen würde.In the case of the previously known bar knot, when the connecting screws extend through the two cover plates and through the intermediate end regions of the bars, they are particularly troublesome the transmission of tensile forces almost all the forces on the connecting screws. The transmission of the tensile forces between the bars in the area of the bar knots takes place indirectly via the connecting screws. The size of the transferable forces and thus also the over-stretched by the supporting structure widths are therefore essentially limited by the stability of the connecting screws. In addition, the node area can not be covered by any glass plate, as this would abut the screw heads or nuts.
Aus der DE-A-38 41 281 ist eine Verbindungsvorrichtung bekannt, bei welcher die Enden von Fachwerkstäben formschlüssig mittels zweier Scheiben miteinander verbunden sind. Jedoch legen die Stabenden nicht aneinander an, so dass sowohl Zug- als auch Druckkräfte über den Formschluss der Verbindungsscheiben übertragen werden muss. Außerdem kann die Seite, auf welcher die Schraube eingesteckt wird, nicht als Auflagefläche für eine Glasscheibe dienen.From DE-A-38 41 281 a connecting device is known in which the ends of truss rods are positively connected to each other by means of two discs. However, the bar ends do not abut one another, so that both tensile and compressive forces must be transmitted via the positive locking of the connecting discs. In addition, the side on which the screw is inserted, not serve as a support surface for a glass.
Die Aufgabe der Erfindung besteht deshalb darin, eine Tragkonstruktion 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 und dass die Einsteckseite auch als Auflagefläche dienen kann.The object of the invention is therefore to develop a support structure of the type mentioned in such a way that the connecting screws are relieved in the transmission of forces through the rod node and thereby significantly larger forces on the rod node can be transmitted between the bars and that the Einsteckseite can also serve as a support surface.
Diese Aufgabe wird erfindungsgemäß mit einer Tragkonstruktion zur Abstützung einer Verglasung gelöst, die die Merkmale des Anspruchs 1 aufweist.This object is achieved with a support structure for supporting a glazing having the features of claim 1.
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. Außerdem sind die Verbindungsschrauben auf der der Verglasung zugewandten Seite in der Abdeckplatte versenkt angeordnet. Dadurch weist die Tragkonstruktion im Bereich der Stabknoten eine ebene Auflagefläche für die Verglasung auf.As the effective surfaces are hereinafter understood those surfaces of the cover plates or the end portions of the rods, which touch each other. For example, the active surfaces can each be provided with a toothing, wherein the teeth of a first active surface engage in the interdental spaces of a second active surface contacting the first active surface, and conversely the teeth of the second active surface engage in the interdental spaces of the first active surface. In addition, the connecting screws on the glazing side facing in the cover plate are sunk. As a result, the support structure in the region of the rod nodes on a flat bearing surface for the glazing.
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.Characterized in that the active surfaces are connected to each other via a positive connection, the compressive and tensile forces are transmitted substantially directly over the cover plates between the rods. Consequently Relieves the connecting screws of compressive and tensile forces. This increases the carrying capacity of the rod node to a considerable extent. As a result, the spanned by the support structure widths can be significantly increased. However, if the spans are not to be increased, the connecting screws can instead be dimensioned correspondingly weaker. This can be done for example by the use of a cheaper screw material, which leads to advantageous cost savings. But the strength of the connecting screws can also be reduced by reducing the dimensions of the screws, which can be realized advantageously smaller-sized rod node.
Dabei sind an den Wirkflächen der Abdeckplatten Vertiefungen und an den Wirkflächen der Endbereiche der Stäbe Vorsprünge ausgebildet, 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 this case, recesses are formed on the active surfaces of the cover plates and projections on the active surfaces of the end regions of the rods, which engage positively in the recesses. This is a simple and at the same time very effective embodiment of the active surfaces with a positive connection between the cover plates and the end portions of the rods. The depressions may be formed, for example, as openings and the projections as pins, which engage positively in the 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 to form the recesses as in the active surfaces of the cover plates recessed annular grooves and the projections as protruding from the active surfaces of the end portions of the rods ring sections which engage positively in the grooves. The rods and the cover plates are according to the tongue and groove principle with each other form-fitting engagement. In this way, the forces acting in the region of the rod node can be transmitted over a large area from the rods to the cover plates and vice versa. As a result, the connecting screws are particularly 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, it is proposed that the rods have in their respective end regions tapering end face regions against which the adjacent rods abut one another in a flat and pressing manner. About these abutting end face areas, the pressure forces can be transmitted from a rod evenly on the adjacent 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.In order to realize a particularly low height of the rod node, it has proved to be advantageous, one or both cover plates in approximately parallel to the active surfaces more or less deeply buried in the end regions of the rods to arrange. Due to the complete countersinking of the cover plate, which faces the glazing, the support structure also has a substantially planar support frame for the glazing in the region of the rod nodes. By a low height of the rod knot, these unobtrusively fit into the overall picture of a slender support structure as possible.
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.Advantageously, the cover plates are designed as circular cover plates. These are particularly easy to manufacture and always meet the symmetry requirements regardless of the number of rods held between the screwed together cover plates.
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.In the rod node advantageously four or six rods are connected to each other. With four bars per bar knot, there are quadrangular areas to be covered with glass panes of the glazing between the bar knots. The support structure may also be formed, for example, by six rods per rod node, such that the rod nodes enclose triangular surfaces to be covered with glass panes.
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°.According to the respective requirements, the angles between adjacent bars of a bar node are preferably in the range between 0 ° and 180 °. In a support structure designed in this way, the forces to be transmitted can still be transferred well to the respectively connected other rods. With four bars per bar knot, the bars of a bar knot are preferably arranged at an angle of approximately 90 ° to each other, with six bars per bar knot, this angle is approximately 60 °.

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.In FIGS. 1 and 2, a rod node according to the invention is designated in its entirety by the reference numeral 1. The bar node 1 is used to connect a plurality of
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
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
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.In order to realize a particularly low height of the rod node, the
