Definitions

  • the invention relates to a rod-shaped scaffolding element for connection to a first projection recess of a scaffolding part.
  • the invention further relates to a scaffolding part with such a scaffolding element and a method for assembling such a scaffolding element.
  • the rod-shaped scaffolding element can be designed in particular in the form of a railing rod or a scaffolding diagonal.
  • the scaffolding component can be designed, for example, in the form of a horizontal bar.
  • connection mechanism typically has a recess on the rod-shaped framework element, which is guided onto a projection on the framework component.
  • a connection mechanism is, for example, from DE 20 2008 001 019 U1 , the US 6,006,862A , the DE 196 33 092 A1 , the DE 10 2004 005 636 A1 , the DE 10 2008 005 814 B4 , the DE 10 2011 014 614 A1 , the EP 0 234 657 A2 , the EP 1 262 611 A2 , the EP 1 589 162 A1 , the GB 901.351A , the GB 1 242 224 A , the JP 2004-076468 A , the JP 2006-226001 A , the U.S.
  • a connection mechanism has become known in which a rod-shaped framework element has a wedge-shaped opening on its end face has, in which a wedge-shaped projection on a scaffolding component in the form of a scaffolding post can be inserted.
  • the WO 2017/013289 A1 discloses a scaffold diagonal with a connecting element having a projection. The connecting element can be inserted into an opening of a further frame part by a pivoting movement.
  • connection mechanisms have the disadvantage that they have complex mechanics with movable components, can only be manufactured at high cost and/or have to be moved during assembly, taking up so much space that assembly in cramped conditions is often impossible. Scaffolding diagonals in particular often have to be swung out over a wide area for assembly. In many cases, however, this swinging out is not possible due to other scaffolding components or building walls.
  • the object of the invention is therefore to provide a rod-shaped scaffolding element that is both structurally simple and can therefore be manufactured inexpensively and can also be easily assembled in a confined space.
  • the object of the invention is also to provide a scaffolding part with such a scaffolding element and a method for assembling such a scaffolding part.
  • top In the context of the present invention, the designations “top”, “bottom”, “horizontal”, “vertical”, etc. refer to the assembled state of the respective component. Furthermore, the term “transverse” means any non-parallel or congruent orientation.
  • the object according to the invention is thus achieved by an elongate scaffolding element in the form of a scaffolding diagonal.
  • the scaffolding element has a scaffolding element body, preferably tubular, on which a first connecting element is attached in the region of a first end of the scaffolding element is arranged or formed.
  • the first connecting element has a projection which can be inserted into a first projection recess of a scaffolding component in order to engage behind an edge of the projection recess.
  • the projection extends transversely to the longitudinal axis of the scaffolding element body.
  • the framework element to be assembled by pivoting the framework element about the longitudinal axis of the framework element body or by pivoting the framework element about an axis which runs parallel to the longitudinal axis of the framework element body.
  • the space required for assembling the scaffolding element is therefore minimal.
  • the scaffolding element is structurally surprisingly simple in design and can therefore be manufactured inexpensively.
  • the projection is preferably formed at a distance from the skeletal element body by a spacing portion of the first connecting element.
  • the longitudinal axis of the projection can extend offset to the longitudinal axis of the framework element body.
  • the longitudinal axis of the projection can be 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 scaffolding member body.

  • the longitudinal axis of the projection can enclose 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.
  • the projection is rigid relative to the framework element body.
  • the first connecting element can be solid and/or designed in one piece.
  • the first connecting element is preferably flattened or rounded on its side facing away from the body of the scaffolding element in order to facilitate pivoting of the scaffolding element.
  • the spacer section can be designed in the shape of a bolt to further simplify production while at the same time providing high stability of the framework element. Manufacture is further simplified if the first connecting element has a U-shaped section molded onto the spacing section.
  • the first connecting element preferably has a cuboid outer contour which prevents twisting of the first connecting element.
  • the U-shaped section of the first connecting element is preferably accommodated in a U-shaped section of the skeletal element body.
  • the framework element has a second connection element on the body of the framework element in the region of the first connection element.
  • the manufacture of the scaffolding element is made significantly easier because, according to the invention, the second connecting element and the first connecting element are of identical design.
  • a securing element for connecting the framework element to a second projection recess can be arranged or formed on the body of the framework element.
  • the securing element is preferably designed to be movable relative to the framework element body.
  • the framework element can also have a safety bolt, in particular in the form of a socket bolt, on which the safety element is preferably arranged, in particular in a pivotable manner.
  • the safety bolt can be designed for at least partial insertion into a second projection recess of a scaffolding component in order to keep the scaffolding element mounted in a torsion-proof manner.
  • the scaffolding element can have a further safety bolt, on which another safety element is preferably arranged, in particular pivotably.
  • the additional safety bolt can be designed for at least partial introduction into a second projection recess of a scaffolding component. Using the second safety bolt, even more different distances or lengths can be covered with one scaffolding element.
