Pattern description

The object of the utility model is a scaffolding element used in a scaffolding, the scaffolding element having a scaffolding tube with a node, whereby the node a) of the scaffolding element bed is connected with the scaffolding tube and / or b) a connection point for connecting the bed is formed.

It is known that scaffolding consists of scaffolding elements, where the scaffolding elements always have a tube with at least one node. In the area of the node, the load on the scaffold element is particularly high. Thus, in the prior art, thick scaffold pipes and / or brackets are used in the area of the node. A disadvantage of such known knot reinforcements is the associated heavy weight of the scaffold element. As scaffolding components are handled and assembled by hand, there is a strong need to reduce their weight.

The function of the utility model is therefore to create a scaffolding element which, at least in the area of the node, is particularly stable, but is nevertheless lightweight.

This task is solved by the scaffolding element for the scaffolding, where the scaffolding element has a scaffolding tube with a node, where on the node - the bed of the scaffolding element is connected to the scaffolding tube and / or - a connection point is formed for the connection of the bed, characterized in that the tube the scaffolding in the area of the node has a first stiffening groove which is less than 25 cm in the first axial direction from the node, where the first stiffening groove reduces the inner diameter of the scaffold tube or increases the outer diameter of the scaffold tube.

Preferably, the second stiffening groove extends towards the circumference of the scaffold tube, the second stiffening groove being provided intermittently or along the circumference towards the circumference of the scaffold tube.

Preferably, the scaffold pipe in the area of the node has a further stiffening groove in the second axial direction which extends opposite to the first axial direction at a distance of less than 15 cm from the node, the further stiffening groove reducing the internal diameter of the scaffold pipe or increasing the external diameter of the scaffold pipe .

Preferably, the further stiffening groove extends towards the circumference of the scaffold tube, the further stiffening groove being interrupted or circumferential towards the circumference of the scaffold tube.

Preferably, the further stiffening groove and the first stiffening groove are axially positioned at the same distance from the node.

Another stiffening groove may run parallel to the longitudinal axis of the scaffold tube. Then, at least three grooves are provided which are distributed around the circumference of the scaffold tube. Alternatively, a further stiffening groove may extend towards the periphery of the scaffold tube, the second stiffening groove being interrupted towards the periphery of the scaffold tube or being provided circumferentially.

The method of production of the previously described scaffold element consists in that a first stiffening groove, a second stiffening groove and / or a further stiffening groove are pressed into the scaffold tube. At the same time, it has turned out that it is possible to press in without the support on the other hand provided by the pin in the scaffold tube, the tolerance ranges for the fabrication of the groove or stiffening grooves nevertheless being complied with. Without a mandrel in the scaffold pipe, pressing in is much more economical and less complicated in terms of construction.
