Description
Die Erfindung bezieht sich auf ein Knotenelement für eine Fachwerkskonstruktion, insbesondere für ein Dachtragwerk eines Gebäudes, wobei das Knotenelement zur Befestigung von Obergurten einen ersten und einen zweiten Gurtflansch aufweist, wobei zum Anschluss mindestens einer Diagonalstrebe ein Strebenflansch vorgesehen ist, welcher von dem zugeordneten Gurtflansch absteht und mit diesem fest verbunden ist, wobei die Obergurte und die Diagonalstreben durch Schraubelemente mit den Gurtflanschen bzw. den Strebenflanschen verbunden sind, wobei an dem ersten Gurtflansch ein Verbindungsdorn befestigt ist, welcher sich etwa rechtwinkelig in Richtung auf den zweiten Gurtflansch zu erstreckt, und wobei der freie Endbereich des Verbindungsdorns in eine dem Querschnitt des Verbindungsdorns angepasste Aufnahmeöffnung des zweiten Gurtflansches längsverschieblich eingreift.The invention relates to a node element for a truss structure, in particular for a roof structure of a building, wherein the node element for attachment of upper straps has a first and a second Gurtflansch, wherein for connecting at least one diagonal strut a Strebenflansch is provided which protrudes from the associated Gurtflansch and is firmly connected thereto, wherein the upper and the diagonal struts are connected by screw elements with the belt flanges or the struts flanges, wherein on the first Gurtflansch a connecting mandrel is fixed, which extends approximately at right angles to the second Gurtflansch, and wherein the free end portion of the connecting pin engages in a cross-section of the connecting mandrel adapted receiving opening of the second Gurtflansches longitudinally displaceable.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Knotenelement für eine Fachwerkskonstruktion nach dem Oberbegriff des Patentanspruches 1 gemäß der
Die Aufgabe wird mit dem Knotenelement gemäß Anspruch 1 gelöst. Das erfindungsgemäße Knotenelement ermöglicht es, herstellungsbedingte Toleranzen der Profilhöhen der Obergurte ohne zusätzliche Maßnahmen aufzunehmen.The object is achieved with the node element according to claim 1. The node element according to the invention makes it possible to record production-related tolerances of the profile heights of the upper belts without additional measures.
Der erste und/oder der zweite Gurtflansch weisen zum Anschluss von Obergurten mit einem T-förmigen oder I-förmigen Querschnitt an die Stege der Obergurte angepasste Schlitze auf. Eine derartige Ausbildung ist an sich bekannt und erhöht bei dem erfindungsgemäßen Knotenelement die Festigkeit und erleichtert die Montage.The first and / or the second Gurtflansch have for connecting upper straps with a T-shaped or I-shaped cross section on the webs of the upper straps adapted slots. Such a design is known per se and increases in the node element according to the invention, the strength and ease of assembly.
Dadurch, dass der zweite Gurtflansch relativ zu dem ersten Gurtflansch über den Verbindungsdorn verschiebbar ist, können selbst große Toleranzen ausgeglichen werden. Außerdem ist sichergestellt, dass die Gurtflansche stets vollflächig an den zugeordneten Obergurten anliegen. Dies erhöht die Stabilität, entlastet die Schraubverbindungen und erleichtert die Montage.The fact that the second belt flange is displaceable relative to the first belt flange via the connecting mandrel, even large tolerances can be compensated. In addition, it is ensured that the belt flanges always rest fully on the associated upper belts. This increases stability, relieves the screw connections and facilitates assembly.
Erfindungsgemäß weist der Verbindungsdorn und die korrespondierende Aufnahmeöffnung in dem zweiten Gurtflansch einen vom runden Querschnitt abweidenden Querschnitt auf. Es versteht sich von selbst, dass die Querschnitte des Verbindungsdorns und der Aufnahmeöffnung mit geringen Toleranzen auszuführen sind, so dass darüber zuverlässige Kräfte übertragen werden können.According to the invention, the connecting mandrel and the corresponding receiving opening in the second belt flange have a cross-section which is different from the circular cross-section. It goes without saying that the cross-sections of the connecting mandrel and the receiving opening are to be designed with small tolerances so that reliable forces can be transmitted via it.
Bevorzugt kann an dem Verbindungsdorn mindestens ein Anschlussflansch für einen Zuggurt angeordnet sein. Solche Zuggurte werden bei Fachwerkskonstruktionen eingesetzt, um bestimmte Abschnitte zu versteifen und/oder Kräfte auf andere Knotenelemente zu übertragen.Preferably, at least one connecting flange for a tension belt can be arranged on the connecting pin. Such Zuggurte be used in truss structures to stiffen certain sections and / or to transfer forces to other node elements.
Es ist auch möglich, den Verbindungsdorn durch den ersten Gurtflansch hindurch zu führen und an dem hindurchgeführten Abschnitt mindestens einen Anschlussflansch für einen Zuggurt anzuordnen.It is also possible to guide the connecting mandrel through the first belt flange and to arrange at least one connecting flange for a tension belt on the section passed through.
Das erfindungsgemäße Knotenelement für eine Fachwerkskonstruktion ist nicht darauf beschränkt, nur die Obergurte und gegebenenfalls daran anschließende Diagonalstreben oder Zuggurte eines Tragwerks zu verbinden. Das vorgeschlagene neue Knotenelement ist vielmehr geeignet, auch an anderen Stellen einer Fachwerkskonstruktion Verwendung zu finden, beispielsweise bei der Verbindung von Untergurten oder sonstigen Trägern.The node element according to the invention for a truss structure is not limited to connecting only the upper chords and optionally adjoining diagonal struts or Zuggurte a supporting structure. The proposed new node element is more suitable to find use in other places of a truss construction, for example, in the connection of lower straps or other straps.
