Abstract

Horizontal und diagonal angeordnete Rohre von Fach­ werkskonstruktionen, z. B. für Dächer von Fabrikshallen, werden in Knotenpunkten zusammengeführt, die Zug- und Druckkräfte aufnehmen müssen. Die Enden der Rohre werden dazu meist flachgequetscht, und die der Quetsch­ zone benachbarte Zone des Rohres folgt einem natürli­ chen, gebauchten Verlauf. Erfindungsgemäß wird dieser Verlauf beim Quetschen der Enden durch zwei trapezför­ mig angeordnete Preßbacken annähernd linear (8) ge­ staltet, wodurch die Ausknickfestigkeit und Beulfestigkeit der Knotenverbindung wesentlich steigt. Der Winkel α, den die beiden sich keilförmig verjüngenden Mantelflächen (8a, 8b) miteinander einschließen, beträgt vorzugsweise 20-28 Grad. Besonders zweckmäßig ist die Anordnung eines Knotenstückes zwischen den flachgequetschten En­ den der Gurt- und Diagonalstäbe, wodurch sich die Ach­ sen der Diagonalstäbe in den Achsen der Gurtstäbe (1) in demselben Punkt treffen; dies schließt jede Exzentrizi­ tät aus und läßt keine Drehmomente entstehen. Horizontal and diagonally arranged tubes from compartment factory constructions, e.g. B. for roofs of factory buildings, are merged into nodes, the train and Have to absorb pressure forces. The ends of the pipes are usually squeezed flat, and the squeeze Zone adjacent zone of the pipe follows a natural one chen, bellied course. According to the invention Course when squeezing the ends by two trapezoidal mig arranged press jaws approximately linear (8) ge shapes, which makes the buckling resistance and buckling resistance the node connection increases significantly. The angle α, the the two tapered lateral surfaces (8a, 8b) with each other is preferably 20-28 degrees. The arrangement is particularly expedient a piece of knot between the flat crushed En that of the belt and diagonal bars, which makes the Ach the diagonal bars in the axes of the belt bars (1) meet on the same point; this excludes every eccentric act and does not create any torques.
