Description
Geschweißter Fachwerkknoten Die Erfindung betrifft einen geschweißten Knoten in einem Fachwerk mit hohlen Diagonalstäben, bei dem die flachgedrückten Enden der Diagonalen mit ihrer Stirnseite durch Stumpfschweißen angeschlossen sind.Welded truss knot The invention relates to a welded one Knot in a framework with hollow diagonal bars, in which the flattened Ends of the diagonals are connected with their end face by butt welding.
Es ist bereits bekannt, die Enden von Hohlstäben flachzudrücken und mit einer Lochplatte oder mit der Schenkelkante eines Gurtwinkels zu verschweißen. Dabei wird das Anschlußblech doppelt so dick ausgeführt wie die Wandung des Hohlprofils. Die zulässige Spannung der Schweißnaht ist aber geringer als die zulässige Stabspannung. Das hat zur Folge, daß bei den bekannten Schweißverbindungen die Stäbe mit Rücksicht auf die Schweißnaht überdimensioniert werden müssen.It is already known to flatten the ends of hollow rods and to be welded with a perforated plate or with the leg edge of a belt bracket. The connecting plate is made twice as thick as the wall of the hollow profile. However, the permissible stress of the weld seam is lower than the permissible bar stress. This has the consequence that in the known welded connections the bars with consideration must be oversized on the weld seam.
Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß die Stabenden aasgestaucht sind. An Hand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert.This disadvantage is avoided according to the invention in that the rod ends are crumbled. An exemplary embodiment of the invention is illustrated with reference to the drawing explained in more detail.
F i g. 1 zeigt eine Ansicht eines Rohrfachwerkknotens; F i g. 2 zeigt den Schnitt nach der Linie A-B in F i g. 1, und F i g. 3 zeigt den Schnitt nach der Linie C-D in Fig. 1.F i g. 1 shows a view of a tubular framework node; F i g. 2 shows the section along the line A-B in FIG. 1, and F i g. 3 shows the section according to the line C-D in FIG. 1.
Das Knotenblech 1 (F i g. 1 und 2) ist mit dem Mantel des Gurtrohres 2 verschweißt und entsprechend der Anzahl der Anschlußstäbe mit Schweißnahtflächen versehen. Die flachgedrückten Enden 7 und 8 der Diagonalstäbe sind gestaucht, und zwar derart, daß die Schweißnahtflächen 3 und 4 des Knotenbleches in Fläche und Form mit den .Schweißflächen 5 und 6 der Stabenden 7 und 8 übereinstimmen. Der Stabquerschnitt ist somit bei der erfindungsgemäßen Knotenverbindung geringer als der Nahtquerschnitt.The gusset plate 1 (Fig. 1 and 2) is with the jacket of the belt tube 2 welded and corresponding to the number of connecting rods with weld seam surfaces Mistake. The flattened ends 7 and 8 of the diagonal bars are upset, and in such a way that the weld seam surfaces 3 and 4 of the gusset plate in surface and Shape with the .Schweißflächen 5 and 6 of the rod ends 7 and 8 match. The rod cross-section is thus smaller than the seam cross-section in the knot connection according to the invention.
Die Erfindung läßt sich nicht nur bei Stahlrohren anwenden, sie kann auch bei anderen Fachwerk-Leichtbauarten mit Vorteil benutzt werden, bei denen Leichtmetalle, z. B. Aluminium, als Baustoff dienen.The invention is not only applicable to steel pipes, it can can also be used with advantage in other lightweight construction types, in which light metals, z. B. aluminum, serve as a building material.
