Description

Knotenpunktverbindung für eiserne Fachwerke aus Rohrstäben Es sind Knotenpunktverbindungen für eiserne Fachwerke aus Rohrstäben bekannt, bei welchen die Rohrstäbe in der gleichen Ebene liegen und mit zwei durch ,einen Längsschlitz voneinander getrennten flach-;epreßten Endlappen das Knotenblech umfassen.Junction point connection for iron trusses made of tubular rods There are Known node connections for iron trusses made of tubular rods, in which the pipe rods lie in the same plane and with two through, a longitudinal slot Flat-pressed end tabs separated from one another encompass the gusset plate.

Die Erfindung betrifft eine Verbesserung einer solchen Knotenpunktverbindung, indem durch die neue Ausführung der Knotenpunktverbindung eine größere Festigkeit gegeben wird, ohne daß die Herstellung selbst zusätzliche Arbeitsgänge erfordert.The invention relates to an improvement of such a node connection, by the new design of the node connection a greater strength is given without the production itself requiring additional operations.

Ohne zusätzliche Versteifungsbauteile lassen sich ferner hierdurch auch bei Verwendung einfacher ebener Knotenbleche allseitig steife Knoten schaffen und somit Rohrfachiverkträger in einfacher Weise und mit geringen Kosten herstellen.Without additional stiffening components, this also allows Create stiff knots on all sides even when using simple flat gusset plates and thus produce tube compartment carriers in a simple manner and at low cost.

Gemäß der Erfindung werden die geschlitzten Endlappen des Rohrstabes durch einen Querflansch miteinander verbunden, der aus dem Rohrstabmaterial gepreßt ist und sowohl den Schlitz überbrückt als auch über die Endlappen lünwegsteht. Eine solche Profilgebung ist in einem Arbeitsgang durch Anwendung geeigneter Preßwerkzeuge möglich. Der Rohrstab, der mit dem Querflansch an dem Knotenblech anliegt, verbindet sich unter Entlastung der Nieten oder Schrauben mit dem Knotenblech in einer auch gegen Biegungsbeanspruchungen genügenden Festigkeit, was z. B. auch bei rahmenartigen Fachwerken vorteilhaft ist.According to the invention, the slotted end tabs of the tubular rod connected to one another by a transverse flange which is pressed from the pipe rod material is and both the slot bridged and lünweg ist over the end tabs. One Such profiling is in one operation by using suitable pressing tools possible. The tubular bar, which rests against the gusset plate with the transverse flange, connects to relieve the rivets or screws with the gusset plate in one too against bending stresses sufficient strength, which z. B. also with frame-like Trusses is beneficial.

Auf der Zeichnung ist eine beispielsweise Verwirklichung der Erfindung wiedergegeben. Abb. i zeigt eine Seitenansicht, Abb. 2 einen Schnitt nach der Linie IV-IV der Abb. i.The drawing shows an example implementation of the invention reproduced. Fig. I shows a side view, Fig. 2 shows a section along the line IV-IV of Fig. I.

i ist das Knotenblech, an dem verschiedene Rohrstäbe 5 und 6 angeschlossen sind. Die Rohrstäbe 6 besitzen in bekannter Weise einfache abgeflachte Endlappen q., mit denen sie das Knotenblech beiderseitig übergreifen. Die Endlappen 3 der Rohrstäbe 5 werden durch Nieten oder Schrauben 7 am Knotenblech befestigt. 8 ist eine aus Festigkeitsgründen angewendete Anschlagkante.i is the gusset plate to which various tubular bars 5 and 6 are connected are. The tubular rods 6 have simple flattened end tabs in a known manner q., with which they overlap the gusset plate on both sides. The end tabs 3 of the Pipe rods 5 are attached to the gusset plate by rivets or screws 7. 8 is a stop edge used for reasons of strength.

Gemäß, der Erfindung wird der Spalt zwischen den Endlappen durch einen Flansch io überbrückt, der auch über die Endlappen hinüberragt, Flansch io und Endlappen sind dabei zweckmäßig iii einem Arbeitsgang aus dem Rohrstabmaterial hergestellt. Wie aus Abb. i und z ersichtlich, findet das Knotenblech i an dem Querflansch io eine- Anlage. Dadurch tritt eine Entlastung der -Verbindungsmittel? ein, was besonders bei dünnwandigen Rohr- und Blechprofilen und leichten Bauwerken zwecks Erhöhung der Festigkeit wichtig ist. Die Erhöhung der Festigkeit bedingt wiederum Material und damit Preisersparnis. Die neue Knotenpunktverbindung läßt sich finit einer einfachen Druck-oder Preßvorrichtung -ebenso leicht herstellen, wie dies etwa für die Herstellung der an sich bekannten Rohrstäbe 6 der Fall ist.According to the invention, the gap between the end tabs is through a Flange io bridged, which also protrudes over the end tabs, flange io and end tabs are expediently made from the tubular rod material in one operation. As can be seen from Fig. I and z, the gusset plate i is located on the transverse flange io a-plant. This results in a relief of the connecting means? a thing special for thin-walled pipe and sheet metal profiles and light structures for the purpose of elevation strength is important. The increase in strength, in turn, requires material and thus price savings. The new node connection can be finitely a simple one Printing or pressing device -just as easy to produce, as is for example for production the known tube rods 6 is the case.

Selbstverständlich ist es nicht unbedingt notwendig, daß die Knotenpunktverbindung im äußersten Ende der Rohrstäbe durchgeführt wird.Of course, it is not absolutely necessary that the node connection is carried out in the extreme end of the pipe rods.
