Abstract
Description
Die Erfindung betrifft einen Stabknoten als Konstruktionselement einer Tragkonstruktion. Die Tragkonstruktion dient zur Abstützung einer Glaswand oder eines Glasdaches. Die Glaswand bzw. das Glasdach setzen sich aus einer Vielzahl von einzelnen Glasscheiben zusammen, die mit gegenseitigem Abstand auf der Tragkonstruktion befestigt sind. Derartige Glaswände oder Glasdächer dienen zur großflächigen Verglasung von Bauteilen.The invention relates to a rod node as a construction element a supporting structure. The supporting structure serves to support a glass wall or a glass roof. The Glass wall or the glass roof consist of a variety of individual panes of glass put together with each other Distance are fixed on the supporting structure. Such Glass walls or glass roofs are used for large-scale glazing of components.
Bekannte Stabknoten der eingangs genannten Art (vgl. FR-A-682 854) sind in Form von zwei sich rechtwinklig oder schiefwinklig kreuzenden Stäben bekannt. Die auf einer derartigen Grundkonstruktion zu befestigenden Glasscheiben haben im Grundriß eine entsprechend viereckige, rautenförmige, quadratische oder rechteckförmige Form. Bei ebenflächigen Tragkonstruktionen bzw. Verglasungsflächen oder bei in lediglich einer Richtung gekrümmter Tragkonstruktion ergeben sich konstruktiv keine Schwierigkeiten; die einzelnen Glasscheiben können entsprechend winkelig aneinanderstoßend auf der entsprechend im Raum einachsig gewölbten Tragkonstruktion aufgelagert und befestigt werden. Probleme ergeben sich aber bei im Raum zweiachsig gekrümmten Verglasungsflächen, da die in sich ebenflächigen Verglasungsscheiben dann nicht mit ihren Eckpunkten gleichzeitig auf allen vier Knoten aufliegen können. Bei geringen Verwölbungen wird versucht, die Glasscheiben elastisch verformt einzubauen. Bei größeren Krümmungsproblemen können entsprechend vorverformte Scheiben oder längs einer Rißlinie gebrochene Scheiben verwendet werden. Known staff nodes of the type mentioned at the beginning (cf. FR-A-682 854) are in shape of two bars crossing at right angles or oblique angles known. The on such a basic construction too fixing glass panes have a corresponding layout square, diamond-shaped, square or rectangular Shape. For flat support structures or glazing areas or when curved in only one direction There are no structural problems with the supporting structure; the individual glass panes can accordingly angularly butting on the corresponding uniaxial in space arched support structure supported and fastened will. However, problems arise with biaxially curved in space Glazing areas, since they are flat in themselves Glazing panes do not have their corner points at the same time can rest on all four nodes. At low Warping is attempted, the glass panes are deformed elastically to install. With larger curvature problems you can do the same preformed disks or broken along a crack line Discs are used.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit anzugeben, um großflächige, im Raum beliebig gekrümmte Tragkonstruktionen problemlos verglasen zu können.The invention is based on this prior art based on the task of specifying a possibility for large-scale, Support structures that are curved in the room without any problems to be able to glaze.
Diese Erfindung ist durch die Merkmale des Anspruchs 1 gegeben.
Ausgehend von dem im Stand der Technik bekannten Stabknoten,
bei dem jeweils mehrere Stäbe durch eine geschraubte
Laschenverbindung zusammengefügt werden können, zeichnet sich
der erfindungsgemäße Stabknoten dadurch aus, daß die Stäbe
mit ihren Endbereichen über jeweils zumindest einen Stirnflächenbereich
kraftschlüssig drückend gegenseitig aneinanderliegen
und in ihren Endbereichen und damit im Bereich des
Stabknotens zwischen zwei Laschenscheiben zusammengeschraubt
gehalten sind. Bei dieser Ausbildung werden die Druckkräfte
durch Flächenkontakt zwischen gestoßenen Stäben übertragen.
Zugkräfte dagegen werden über die beidseitig den Stoßbereich
überdeckenden, miteinander verschraubten Laschenscheiben
übertragen. Auch Biegekräfte können gut übertragen werden. So
können die bei der Zerlegung eines Biegemoments entstehenden
Zug- und Druckkräfte in der oben genannten Weise in dem Stabknoten
entweder - beim Auftreten von Zugkräften - durch die
eine oder andere Laschenscheibe oder - beim Auftreten von
Druckkräften - durch die Stirnflächenbereiche der aneinanderstoßenden
mehreren Stäbe übertragen werden.This invention is given by the features of
Als vorteilhaft hat sich herausgestellt, die Endbereiche der in einem Knoten sich stoßenden Stäbe mit sich zum Ende hin verjüngenden Stirnflächenbereichen auszubilden. Mit diesen Stirnflächenbereichen stoßen dann benachbarte Stäbe aneinander. Dadurch kann die Bauhöhe im Bereich der Knoten niedrig gehalten werden. Je weniger Stäbe in einem Knoten aufeinandertreffen, desto schlanker erweist sich die Tragkonstruktion. Bei vier-stäbigen Knoten ergeben sich viereckige, von Glasscheiben abzudeckende Flächen zwischen den Knoten. Da die Stäbe im Bereich eines Knotens mit unterschiedlichen Neigungen aufeinandertreffen können, können die Glasscheiben ebenflächig sein.The end regions of the in a knot pushing rods with each other towards the end form tapered end face areas. With these End face areas then abut adjacent bars. As a result, the overall height in the area of the nodes can be low being held. The fewer rods meet in a knot, the slimmer the supporting structure turns out to be. Four-knot knots result in square, from Areas of glass to be covered between the nodes. Since the Bars in the area of a node with different inclinations can meet, the glass panes can be flat be.
Die Fachwerkkonstruktion kann auch so ausgebildet werden, daß die Stabknoten dreieckige Flächen einschließen. Dann können in ihrer Grundfläche dreieckige Glasscheiben bei der Verglasung verwendet werden. Immer ist unter jedem freien Rand der Glasscheibe ein Stab der Tragkonstruktion vorhanden. Damit können beliebig gekrümmte Tragkonstruktionen ausgebildet und verglast werden. Entsprechend den jeweiligen Anforderungen sind die Winkel zwischen benachbarten Stäben vorzugsweise im Bereich größer als Null Grad und kleiner als 180 Grad. Bei einer derartigen Konstruktion lassen sich die übertragenden Lasten noch gut auf die jeweils angeschlossenen anderen Stäbe übertragen.The truss structure can also be designed so that the rod nodes include triangular faces. Then can in its base triangular glass panes in the glazing be used. There is always the under each free edge Glass pane a rod of the supporting structure available. In order to can arbitrarily curved support structures and be glazed. According to the respective requirements are the angles between adjacent bars preferably in Range greater than zero degrees and less than 180 degrees. At Such a construction can be the transmitting Loads well on the other rods connected transfer.
Um die Tragkonstrukion konstruktiv nicht zu hoch ausbilden zu müssen, hat es sich als sinnvoll herausgestellt, eine oder beide Laschenscheiben mehr oder weniger stark versenkt in den Endbereichen der Stäbe vorzusehen. Dadurch geraten die durch sie hindurchgehenden Schraubenköpfe nicht in Kollision mit den die Stäbe und Stabknoten von oben abdeckenden Glasscheiben.In order not to construct the supporting structure too high , it turned out to be useful, one or both plate washers more or less sunk into the Provide end areas of the rods. This will get them through screw heads passing through them do not collide with the glass panes covering the rods and rod nodes from above.
Die Endbereiche der Stäbe können in einem Knoten unter beliebigen Winkeln zusammentreffen. Die Knoten einer Tragkonstruktion werden daher untereinander oftmals konstruktiv nicht identisch ausgebildet sein. Die fertigungsmäßigen Anforderungen an die Ausbildung der an einem Knoten vorhandenen Bauteile ist daher extrem hoch. Dieser Aufwand läßt sich praktisch nur mit rechnergestützter Konstruktionsarbeit bewältigen. Um das dem Rechner zugrundeliegende Linienraster konstruktiv in ein Stabknoten-Raster korrekt und einfach umsetzen zu können, hat es sich als sinnvoll herausgestellt, das Linienraster in der Mitte der oberen Fläche der einzelnen Stäbe anzuordnen. Diese Rasterlinien oder Systemlinien stoßen sich dann jeweils in einem Punkt eines jeden Knotens. Von diesem theoretischen Knotenpunkt wird dann nach "unten" der Knoten konstruiert. Um den statischen Anforderungen gerecht zu werden, werden dabei die Laschenscheiben gegebenenfalls soweit in die Stabenden versenkt, daß zwischen ihnen immer ein vorgegebener Abstand vorhanden ist. Da auch die Laschenscheiben eine konstante Dicke und Ausbildung in jedem Knoten haben, können für alle Knoten daher vergleichbare Rechenvoraussetzungen zugrundegelegt werden.The end areas of the bars can be in any node under any Angles meet. The nodes of a supporting structure are therefore often not constructive with each other be identical. The manufacturing requirements the formation of the components present at a node is therefore extremely high. This effort can be practically only cope with computer-aided design work. Constructively around the line grid on which the computer is based implement it correctly and easily in a bar knot grid To be able to, it has proven to make sense that Line grid in the middle of the top surface of each Arrange bars. These grid lines or system lines meet then in a point of each node. From this theoretical node is then "down" the Knot constructed. To meet the static requirements to be, the tab plates if necessary sunk so far into the rod ends that always between them there is a predetermined distance. Since the tab washers a constant thickness and formation in every knot have comparable computing requirements for all nodes be taken as a basis.
Die Verglasung für eine derartige Tragkonstruktion kann aus einer einzelnen Scheibe oder aus einer mehrere Scheiben umfassenden Einfach- oder Isolierglasscheibe bestehen. Die Glasscheiben können auch durch nicht durchsichtige Platten ersetzt werden. Als konstruktiv einfach und technisch voll zufriedenstellende Lösung hat sich eine Verglasung erwiesen, bei der eine von außen zusätzlich einwirkende Abdeckplatte auf die obere Laschenscheibe gepreßt wird. Die Ränder der Glasscheibe sind damit im Bereich der Knoten zwischen zwei Scheiben eingepreßt. Eine der Scheiben ist die bei der konstruktiven Ausbildung des Knotens vorhandene Abdeckscheibe. Die andere Scheibe ist auf der Außenseite der Verglasung zusätzlich vorhanden. Diese zusätzliche Scheibe kann auf konstruktiv einfache Weise über eine Verschraubung an der äußeren Laschenscheibe befestigt werden.The glazing for such a supporting structure can be made of a single disk or a disk comprising several disks Single or insulating glass pane exist. The Panes of glass can also be seen through opaque panels be replaced. As structurally simple and technically full satisfactory solution has been glazing, with an additional cover plate acting from the outside is pressed onto the upper plate. The edges of the Glass pane are thus in the area of the nodes between two Pressed discs. One of the disks is that of the constructive one Formation of the existing cover plate knot. The other pane is on the outside of the glazing available. This additional disc can be constructive on simple way via a screw on the outer Tab plate can be attached.

In einem in Fig. 1 dargestellten Stabknoten 10 treffen im
vorliegenden Beispielsfall sechs Stäbe 12, 14, 16, 18, 20, 22
aufeinander. Die Stäbe sind Teil einer Tragkonstruktion. Die
Knoten können dann derart innerhalb der Tragkonstruktion vorhanden
sein, daß die die Knoten verbindenden Stäbe dreieckige
Flächen einrahmen. Diese Flächen können auch viereckig, und
damit beispielsweise Trapezflächen sein.In a
Jeder der Stäbe 12 bis 18 besteht aus einem Rechteckprofil
von im vorliegenden Beispielsfall 40 mm (Millimeter) Breite
13 und 60 mm Höhe 15. Die beiden Seitenflächen 24, 26 laufen
im jeweiligen Endbereich 28 des betreffenden Stabes spitz
aufeinander zu. Jeder Stab 12 bis 22 besitzt dadurch zwei
spitz zulaufende, schräge Stirnflächenbereiche 30, 32. Benachbarte
Stäbe, beispielsweise die Stäbe 18 und 16, liegen
mit ihren benachbarten Stirnflächenbereichen 30, 32 flächig
aneinander. Dies trifft für alle Stäbe und alle Stirnflächenbereiche
der verschiedenen Stäbe in einem Stabknoten zu.
Druckkräfte können auf diese Weise durch Kontakt über die
Stirnflächenbereiche 30, 32 auf benachbarte Stäbe eines Stabknotens
10 übertragen werden.Each of the
Die Endbereiche 28 der Stäbe 12 bis 22 weisen innerhalb des
Stabknotens 10 eine gegenüber dem übrigen Stabbereich verringerte
Stabhöhe 17 von im Beispielsfall 40 mm auf. In die dadurch
ausgebildeten beiden verjüngten Höhenbereiche 19, 21
ragen von oben und von unten eine Abdeckscheibe 34 bzw. 36.
Diese beiden Abdeckscheiben 34, 36 werden im Bereich eines
jeden Endbereichs 28 der gestoßenen Stäbe von einem Gewindebolzen
40 miteinander verschraubt zusammengehalten. Die Gewindebolzen
können dabei unter Vorspannung stehen. Die Köpfe
42 der Bolzen 40 sind in der oberen Abdeckscheibe 34 versenkt
angeordnet. Der Bolzen 40 ragt unten aus der unteren Abdeckscheibe
36 heraus. Auf das dort sichtbare Außengewinde 44 ist
eine Mutter 46 geschraubt. Diese Mutter 46 liegt über eine
Scheibe 48 fest an der Abdeckscheibe 36 an. Das Außengewinde
44 ist am Gewindebolzen 40 derart vorhanden, daß es innerhalb
der unteren Abdeckscheibe 36 endet und nicht in den Bereich
der Stirnflächenbereiche 30, 32 hineingreift. Die Abdeckscheiben
34, 36 sind so paßgenau in die beiden verjüngten
Höhenbereiche 19, 21 eingesetzt, daß eine Übertragung von
Druckkräften auch in diesen beiden Höhenbereichen möglich
ist. Für die Übertragung von Druckkräften steht daher auch im
stabmäßig geschwächten Endbereich 28 eines jeden Stabes ein
dem ungeschwächten Stabquerschnitt vergleichbarer Querschnitt
zur Verfügung. Die versenkte Anordnung der insbesondere oberen
Abdeckscheibe 34 in den Stäben sowie die versenkte Anordnung
der Schraubenköpfe 42 in den Abdeckscheiben 34 ermöglicht
es, die obere Seite der Stäbe im Bereich eines Knotens
10 höhenmäßig praktisch durchlaufen zu lassen.The
In der oberen Abdeckscheibe 34 ist eine zentrische Bohrung 50
mit einem Innengewinde 52 vorhanden. In dieses Innengewinde
52 kann eine Schraube 78 von oben eingeschraubt werden, wie
nachstehend noch näher beschrieben wird. A
Auf dem in Fig. 1 und 2 dargestellten Stabknoten 10 liegt
eine Verglasung 56. Diese Verglasung besteht im vorliegenden
Beispielsfall aus einer Isolierverglasung 56, die aus einer
unteren Scheibe 58 und einer dazu im Abstand angeordneten
oberen Scheibe 60 in üblicher Weise zusammengesetzt ist. Diese
Verglasung 56 liegt auf Dichtungsprofilen 62, 64 auf. Diese
Dichtungsprofile 62, 64 bedecken die oberen Seiten der
Stäbe 12 bis 22 und umgreifen die oberen beiden Längskanten
der Stäbe mit nach unten auskragenden Lappen 66, 68. Die
Dichtungsprofile 62, 64 besitzen einen mittig nach oben auskragenden
Steg 70. Dieser Steg 70 ragt zwischen den Stirnbeziehungsweise
Seitenflächen der Verglasung 56 nach oben
hindurch. Auf dem Steg 70 sitzt von oben eine Dichtungsmasse
72, die in der Ebene der oberen Scheibe 60 eine wasserdichte
Verbindung zwischen den oberen Scheiben 60 darstellt.Is on the
Im Bereich eines jeden Knotens und damit auch des Knotens 10
wird die Verglasung 56 und damit die obere Scheibe 60 von
oben durch eine Silikon-Scheibe 74 abgedeckt. Auf dieser
Scheibe 74 liegt von oben eine äußere Scheibe 76 auf. Die
Scheiben 74, 76 besitzen eine zentrische Aussparung, durch
die von außen eine Schraube 78 hindurchgreift, die in einem
