Description

The invention relates to a rod-shaped framework element for connection to a first projection recess of a framework part. The invention further relates to a scaffolding part with such a scaffolding element and a method for mounting such a scaffolding element.

It is known to provide a simple connection mechanism for connecting a rod-shaped frame element to a frame component. The rod-shaped framework element can be designed in particular in the form of a railing rod or a framework diagonal. The scaffold component can be designed, for example, in the form of a horizontal bar.

The attachment mechanism typically has a recess on the rod-shaped frame element, which is guided on a projection on the frame component. Such a connection mechanism is for example from the DE 20 2008 001 019 U1 , of the US 6,006,862 A , of the DE 196 33 092 A1 , of the DE 10 2004 005 636 A1 , of the DE 10 2008 005 814 B4 , of the DE 10 2011 014 614 A1 , of the EP 0 234 657 A2 , of the EP 1 262 611 A2 , of the EP 1 589 162 A1 , of the GB 901,351 A , of the GB 1 242 224 A , of the JP 2004-076468 A , of the JP 2006-226001 A , of the US 2,681,834 A , of the US 2,845,307 A. and the US 3,323,271 A known. Furthermore, from the DE 1 559 069 A a connection mechanism has become known in which a rod-shaped frame element has on its end face a wedge-shaped opening into which a wedge-shaped projection on a frame component in the form of a scaffolding handle can be inserted.

The known connection mechanisms have the disadvantage that they have a complex mechanism with moving components, can only be produced at high costs and / or must be moved during installation with so much space that an assembly in cramped conditions is often impossible.

In particular, scaffolding diagonals often have to be swung out over a wide area to assemble them. However, this swinging is not possible in many cases due to other scaffolding components or building walls.

The object of the invention is therefore to provide a rod-shaped scaffolding element, which is both structurally simple and therefore cost-manufacturable as well as in a simple manner in a small space can be mounted. The object of the invention is further to provide a scaffolding part with such a scaffolding element and a method for assembling such a scaffold part.

This object is achieved by a scaffold element having the features of claim 1, a scaffold part having the features of claim 12 and a method for assembling a scaffold element according to claim 14. The dependent claims give preferred developments again.

In the context of the present invention, the terms "top", "bottom", "horizontal", "vertical", etc. refer to the mounted state of the respective component. Furthermore, the term "transverse" is understood to mean any non-parallel or congruent alignment.

The object of the invention is thus achieved by a longitudinally extending framework element in the form of a framework diagonal. The scaffold element has a, preferably tubular, scaffold element body on which a first connecting element is arranged or formed in the region of a first end of the scaffold element. The first connection element has a projection which can be inserted into a first projection recess of a frame component in order to engage behind an edge of the projection recess. The projection extends transversely to the longitudinal axis of the framework element body.

This makes it possible to mount the scaffold element by pivoting the scaffold element about the longitudinal axis of the scaffold element body or by pivoting the scaffold element about an axis that runs parallel to the longitudinal axis of the scaffold element body. The space required for mounting the scaffolding element is minimal. In addition, the framework element is structurally surprisingly simple and thus cost manufacturable.

The protrusion is preferably formed by a spacing section of the first connecting element distanced from the skeleton body. The longitudinal axis of the projection may extend offset relative to the longitudinal axis of the skeleton body. The scaffold element is characterized particularly easy to pivot for mounting it to the scaffold component.

In addition to the offset orientation of the longitudinal axis of the projection to the longitudinal axis of the framework element body, the longitudinal axis of the projection at an angle of 90 ° ± 30 °, in particular at an angle of 90 ° ± 20 °, preferably at an angle of 90 ° ± 10 °, extend to the longitudinal axis of the scaffold element body.

The spacing section is preferably formed together with the projection L-shaped. The longitudinal axis of the spacer section may be an angle of 90 ° ± 30 °, in particular a Angle of 90 ° ± 20 °, preferably an angle of 90 ° ± 10 °, with the longitudinal axis of the framework element body include. The longitudinal axis of the projection may include an angle of 90 ° ± 30 °, in particular an angle of 90 ° ± 20 °, preferably an angle of 90 ° ± 10 °, with the longitudinal axis of the spacer section.

In a particularly preferred embodiment of the scaffold element of the projection is rigidly formed relative to the scaffold element body.

The first connection element can be solid and / or integral.

The first connecting element is preferably flattened or rounded on its side facing away from the framework element body in order to facilitate the pivoting of the framework element.

The spacing section can be designed to be bolt-shaped for further facilitated production while maintaining high stability of the framework element.

The production is further simplified if the first connecting element has a U-shaped portion formed on the spacer section.

The first connecting element preferably has a cuboid outer contour, which prevents a rotation of the first connecting element.

The U-shaped section of the first connection element is preferably accommodated in a U-shaped section of the framework element body.

The scaffold element may have a second connecting element on the scaffold element body in the region of the first connecting element. As a result, different distances from each other spaced portions of the frame part can be connected by means of the scaffolding element.

The manufacture of the framework element is significantly facilitated if the second connection element and the first connection element are of the same design.

At the second end of the scaffold element, a securing element for connecting the scaffold element to a second protrusion recess can be arranged or formed on the scaffold element body. The securing element is preferably designed to be movable relative to the framework element body.

The scaffolding element can furthermore have a securing bolt, in particular in the form of a plug-in bolt, on which the securing element, in particular pivotable, is preferably arranged. The securing bolt can be designed for at least partial introduction into a second projection recess of a scaffold component in order to hold the scaffold element mounted secured against rotation.

The scaffolding element may have in the region of the securing bolt a further securing bolt on which preferably a further securing element, in particular pivotable, is arranged. The further securing bolt can be designed for at least partial introduction into a second projection recess of a framework component. By means of the second securing bolt even more different distances or lengths can be covered with a scaffolding element.

The object of the invention is further achieved by a scaffold part with a scaffold component, a first protrusion recess and a scaffold element described above, wherein the scaffold element is mounted on the first protrusion recess, that the projection of the first connecting element, the edge of the first protrusion -Easnehmung engages behind.

In a further preferred embodiment of the framework part, the first projection recess is provided in a frame component which is in the form of a horizontal connector, i. a horizontally arranged or arranged Gerstriegel, is formed.

The invention further relates to a scaffold with a scaffold part described above.

1. A) inserting a first projection of the framework element into a first projection recess of the framework component;
2. B) pivoting of the scaffold element about the longitudinal axis of the scaffold element body or about an axis parallel to the scaffold element body, so that the first projection at least partially engages behind the edge of the first protrusion recess.
