Definitions

  • the previously described carrier head of the scaffolding element is generally used to transfer a vertical load into a scaffolding.
  • concrete formwork can be placed or mounted on the carrier head.
  • the girder head can also be used as a temporary support for renovations.
  • the document DE4027739 discloses such a scaffolding element.
  • the object of the present invention is now to provide a framework element which can transfer significantly more vertical load via the girder head without being made significantly more massive and heavier.
  • the object of the present invention is also to provide a scaffolding with such a scaffolding element.
  • the object according to the invention is thus achieved by a scaffolding element for a scaffolding.
  • the framework element has a carrier head with a threaded spindle.
  • the scaffolding element also has a scaffolding tube with a spindle receiving section.
  • the threaded spindle is partially inserted into the spindle receiving section.
  • the spindle receiving section is located at a first axial end of the scaffold tube.
  • a spindle nut is mounted on the threaded spindle in such a way that the carrier head, when the scaffolding element is mounted vertically, introduces its load into the scaffolding tube via the threaded spindle.
  • the spindle receiving section has a first spindle positioning groove which reduces the inside diameter of the scaffold tube.
  • the first spindle positioning groove significantly improves the vertical load-bearing capacity of the framework element without significantly increasing the weight of the framework element.
  • the first spindle positioning groove increases the load-bearing capacity of the scaffolding element in two ways: On the one hand, the strength of the scaffolding tube in the area of the first spindle positioning groove is increased due to the shape of the first spindle positioning groove. On the other hand, the threaded spindle is better aligned in the scaffold tube due to the reduced inner diameter of the scaffold tube at the first spindle positioning groove. Overall, this results in a considerably improved suitability of the scaffold element for vertical load transfer.
  • the threaded spindle is aligned as centered as possible in the scaffolding tube by the first spindle positioning groove, with a clearance fit between the threaded spindle and the scaffolding tube for inserting the threaded spindle into the scaffolding tube.
  • the longitudinal axis of the threaded spindle has the angle ⁇ with respect to the longitudinal axis of the scaffolding tube, the angle ⁇ being less than 1 °, in particular less than 0.8 °, preferably less than 0.7 °.
  • the vertical load is thereby introduced as centrally as possible into the scaffolding tube in order to keep the moments occurring in the scaffolding small.
  • the first spindle positioning groove can extend parallel to the longitudinal axis of the scaffold tube. At least three grooves distributed over the circumference of the scaffolding tube are preferably provided for aligning the threaded spindle. In a preferred embodiment of the first spindle positioning groove, however, it extends in the circumferential direction of the scaffolding tube.
  • the first spindle positioning groove can be interrupted in the circumferential direction of the scaffolding tube or formed circumferentially.
  • a particularly effective centering of the threaded spindle in the scaffold tube takes place when the axial distance of the first spindle positioning groove from first axial scaffold tube end is smaller than the inner diameter of the spindle receiving portion.
  • the spindle receiving section also has a second spindle positioning groove.
  • the second spindle positioning groove is axially spaced from the first spindle positioning groove and reduces the inside diameter of the scaffold tube.
  • the second spindle positioning groove defines the alignment of the threaded spindle in the scaffolding tube by at least two axially spaced spindle positioning grooves, whereby the alignment, in particular the centering, of the threaded spindle is particularly precise.
  • the second spindle positioning groove can extend parallel to the longitudinal axis of the scaffold tube. At least three grooves distributed over the circumference of the scaffolding tube are preferably provided for aligning the threaded spindle.
  • the second spindle positioning groove can extend in the circumferential direction of the scaffold tube. In this case, the second spindle positioning groove can be interrupted in the circumferential direction of the scaffolding tube or formed circumferentially.
  • the spindle receiving section has a third spindle positioning groove.
  • the third spindle positioning groove is axially further spaced from the first spindle positioning groove than the second spindle positioning groove.
  • the third spindle positioning groove reduces the inner diameter of the scaffold tube. The alignment, in particular the centering, of the threaded spindle in the scaffolding tube is further improved by the third spindle positioning groove.
  • the third spindle positioning groove can extend parallel to the longitudinal axis of the scaffold tube. There are preferably at least three over the Grooves distributed around the scaffold tube are provided for aligning the threaded spindle. Alternatively, the third spindle positioning groove can extend in the circumferential direction of the scaffold tube. The third spindle positioning groove can be interrupted in the circumferential direction of the scaffolding tube or formed circumferentially. The third spindle positioning groove is preferably less spaced axially from the second spindle positioning groove than the second spindle positioning groove is spaced from the first spindle positioning groove.
  • the second spindle positioning groove reduces the inner diameter of the scaffolding tube just as much as the first spindle positioning groove.
  • the third spindle positioning groove can also reduce the inner diameter of the scaffold tube. The radial play of the threaded spindle in the scaffold tube is thereby significantly reduced, the threaded spindle nevertheless remaining easy to insert into the scaffold tube.
  • the scaffold tube can have a pin receiving section at its second axial scaffold tube end, which is opposite the first axial scaffold tube end, into which a pin of a further scaffold element can be inserted.
  • the pin receiving section can have a first pin positioning groove which reduces the inner diameter of the scaffold tube.
  • the scaffold tube is mechanically reinforced in the area of the pin receiving section by the first pin positioning groove.
  • the first pin positioning groove can extend parallel to the longitudinal axis of the scaffold tube. At least three grooves distributed over the circumference of the scaffolding tube are preferably provided for aligning the threaded spindle. Alternatively, the first pin positioning groove can extend in the circumferential direction of the scaffold tube. The The first pin positioning groove can be interrupted in the circumferential direction of the scaffolding tube or formed circumferentially.
  • the axial distance between the first pin positioning groove and the second axial scaffold tube end is preferably smaller than the inner diameter of the first pin positioning groove.
  • the pin receiving section has a second pin positioning groove which is axially spaced from the first pin positioning groove and which reduces the inside diameter of the scaffold tube.
  • the pin of a further framework element is thereby centered on two pin positioning grooves that are axially spaced from one another in the pin receiving section.
  • the second pin positioning groove can extend parallel to the longitudinal axis of the scaffold tube. At least three grooves distributed over the circumference of the scaffolding tube are preferably provided for aligning the threaded spindle. Alternatively, the second pin positioning groove can extend in the circumferential direction of the scaffold tube. The second pin positioning groove can be interrupted in the circumferential direction of the scaffolding tube or formed circumferentially.
  • the scaffold tube has a further stiffening groove in the area of the junction, which is spaced less than 15 cm from the junction in a second axial direction and reduces the inner diameter of the scaffold tube or increases the outer diameter of the scaffold tube.
  • the second axial direction is opposite to the first axial direction.
  • the nodal point is reinforced by a further stiffening groove in both axial directions by a stiffening groove in each case.
  • the spindle positioning groove (s) and the stiffening groove (s) preferably reduce the inside diameter of the scaffold tube to the same extent.
