Description

Die Erfindung betrifft ein vertikales Gerüstrohr, an dem mindestens eine Haltevorrichtung angebracht ist, in die horizontale und/oder diagonale Gerüstrohre einhängbar sind.The invention relates to a vertical scaffold tube, on which at least one Holding device is attached in the horizontal and / or diagonal scaffolding tubes are attachable.

Vertikale Gerüstrohre, an denen Haltevorrichtungen für horizontale und/oder diagonale Gerüstrohre angebracht sind, werden im Gerüstbau vielfältig eingesetzt. Zum Verbinden der horizontalen und/oder diagonalen Gerüstrohre mit den vertikalen Gerüstrohren, werden die Auflageköpfe der horizontalen und/oder diagonalen Gerüstrohre in die Haltevorrichtungen der vertikalen Gerüstrohre eingehängt und dann mit einem Keil festgeklemmt. Durch dieses Festklemmen wird die Anlagefläche des Auflagekopfes fest gegen das vertikale Gerüstrohr gedrückt, so daß eine kraft- und formschlüssige Verbindung zwischen dem Auflagekopf und dem Gerüstrohr entsteht, durch die im Zusammenspiel mit der Haltevorrichtung alle Kräfte und Momente von den horizontalen und/oder diagonalen Gerüstrohren in das vertikale Gerüstrohr eingeleitet werden. Dementsprechend treten in dem vertikalen Gerüstrohr um die Haltevorrichtung herum Spannungsspitzen auf, die oftmals dazu führen, daß das vertikale Gerüstrohr an diesen Stellen eingedrückt oder auf eine andere Art beschädigt wird. Um dieses Beschädigungen zu vermeiden, ist die Wandstärke der Gerüstrohre erhöht worden, was ein höheres Gewicht dieser Bauteile und damit ein schlechteres Handling zur Folge hat.Vertical scaffolding tubes on which holding devices for horizontal and / or diagonal scaffold tubes are attached, are used in a wide variety of scaffolding. For connecting the horizontal and / or diagonal scaffold tubes with the vertical ones Scaffold tubes, the support heads are horizontal and / or diagonal Scaffold tubes hooked into the holding devices of the vertical scaffold tubes and then clamped with a wedge. By this clamping the contact surface of the support head pressed firmly against the vertical scaffold tube, so that a force and positive connection between the support head and the scaffold tube arises through which, in interaction with the holding device, all forces and Moments from the horizontal and / or diagonal scaffold tubes into the vertical Scaffold tube to be introduced. Accordingly occur in the vertical scaffold tube voltage peaks around the holding device, which often lead to the fact that the vertical scaffold tube pressed in at these points or in another way is damaged. To avoid this damage, the wall thickness is the Scaffolding tubes have been increased, which means a higher weight of these components and therefore one worse handling results.

Es stellt sich deshalb die Aufgabe, ein Gerüstrohr zur Verfügung zu stellen, das eine bessere Lastaufnahmefähigkeit aufweist. It is therefore the task to provide a scaffold tube, the one has better load-bearing capacity.

Die Aufgabe wird erfindungsgemäß durch die Bereitstellung eines vertikalen Gerüstrohres gelöst, an dem mindestens eine Haltevorrichtung angebracht ist, in die horizontale und/oder diagonale Gerüstrohre einhängbar sind, wobei das Gerüstrohr in dem Bereich, in dem die Haltevorrichtung an dem vertikalen Gerüstrohr angebracht ist, jeweils eine Verstärkung aufweist.The object is achieved by the provision of a vertical Scaffold released, on which at least one holding device is attached, in the horizontal and / or diagonal scaffold tubes can be suspended, the scaffold tube in the area in which the holding device on the vertical scaffold tube is attached, each has a reinforcement.

Die Wandstärke der Manschette beträgt vorzugsweise das 0,5-1,5 fache der Wandstärke des vertikalen Gerüstrohres. Die Länge der Manschette beträgt vorzugsweise das 1-2 fache des Gerüstrohrdurchmessers.In another preferred embodiment, the gain is with a Cuff achieved, which is pushed over the vertical scaffold tube and then outside preferably shrunk, pressed or welded on.

Der Abstand des Rings von der Haltevorrichtung beträgt vorzugsweise das 0,2-1,0 fache des Rohrdurchmessers. Die Wandstärke beträgt vorzugsweise das 0,5-1,5 fache der Wandstärke des vertikalen Gerüstrohres.
