Definitions

  • the invention relates to a scaffolding element with parallel spaced tubes and connected by transverse tube struts, according to the preamble of claim 1.
  • the tubes are usually provided at one end with pins for plugging together with other scaffolding elements, their tube struts near the Pipe ends attached.
  • scaffolding for several floors can be built one above the other and for longer front lengths by simply plugging these individual elements together and connecting them together.
  • auxiliary or holding devices are provided in order to save the. Planks for accessing the individual scaffolding levels must also be fitted with railings and other protective devices.
  • upwardly directed retaining pins are welded to the transverse tube struts - round or angular cross-section, but preferably only to the upper transverse tube strut. These engage when the planks are placed in the holes provided there, so that these planks are fixed un displaceably in both the longitudinal and transverse directions.
  • a molded part fixed to a pipe strut for fastening planks is known, which partially encompasses the pipe strut from above by means of a bow-shaped connecting web, the ends of the bow-shaped connecting web forming laterally projecting webs having retaining pins are shaped to support planks.
  • the inventor has set itself the goal of eliminating the identified shortcomings and improving the above-mentioned component, simplifying the attachment of these retaining pins in that less working time and at the same time higher accuracy is achieved, in particular also the transmission of the horizontal forces to make it cheaper and to avoid tearing.
  • the fitting which partially surrounds the tubular strut is preferably connected to it by welding.
  • the shaped part according to the invention preferably consists of extruded aluminum parts, but can also be made of another material, such as steel.
  • the holding pins of the shaped piece have a diameter between 15 and 20 mm and a free length between 30 and 60 mm, and further that the holding pins are arranged on both sides of the tubular strut at a distance between 30 and 60 mm from each other are.
  • the retaining pins are therefore attached in pairs on both sides of the tubular strut, and each of the retaining pins engages in one of the holes in each successively adjacent plank.
  • the planks lie on the web of the fitting and over this the transverse tube strut.
  • four holding pins connected to a single base or two separate bases, which form the shaped piece are fastened to a tube strut. It is particularly expedient if eight holding pins are arranged on a tubular strut, two or four of which are optionally connected to a base. It has also proven to be advantageous to attach two pairs of retaining pins each at a distance of approximately 220 to 280 mm from one another on a tubular strut and to select the distance between adjacent pairs of retaining pins in the central region at approximately 40 to 80 mm.
  • the horizontal forces introduced - for example also influenced by wind forces - no longer act on lateral weld seams.
  • weld seams occur in the subject matter of the invention, they only serve to fix the parts; the forces are introduced directly into the nearest plank plane or into the cross-section of the transverse pipe strut via the coherent and form-fitting unit fitting / pipe strut.
  • two scaffolding elements 1 are set up by means of indicated foot elements 8.
  • the scaffolding elements 1 each consist of tubes 2 running in parallel at a distance, which are connected to one another at their end regions by means of two transverse tube struts 3.
  • plug pins 9 are provided on the upper ends of the tubes for plugging together with other scaffolding elements or other supplementary parts.
  • Diagonal struts 13 run between the two scaffolding elements 1.
  • the upper transverse pipe strut 3 is provided with holding pins 5 which, when laying planks 10 on the pipe strut 3, engage in holes prepared there - for reasons of clarity not recognizable in the drawing - so that the planks 10 both in the transverse and in the longitudinal direction are set.
  • a plug-on element 11 is also shown in FIG. 1, which serves to hold the planks 10 in their resting position on the tubular strut 3, so that they cannot jump upwards out of the fixing by means of the holding pins 5.
  • a further scaffolding element 1 can also be attached.
  • FIG. 2 shows a scaffold element 1 according to the invention in detail.
  • the two parallel tubes 2 are connected below and above by means of the transverse tube struts 3.
  • the upper tubular strut 3 is provided with the holding pin 5 for fastening the planks 10.
  • a fitting 4 consisting of two holding pins 5 and a cross-sectionally U-shaped base 7 can be seen in FIG. 3.
  • This fitting 4 rests with its base 7 on the top and the sides of the tubular strut 3, which here has a rectangular cross section.
  • the shaped piece 4 can completely enclose three sides of the tubular strut 3 or - as illustrated in FIG. 3 - can be equipped with only short legs 30 on the sides.
  • the molded piece 4 can either be welded to the tubular strut (right half of the figure), or it can be fastened by means of screwing or riveting 14 (left half of the figure).
  • the diameter d of the holding pin 5 here is approximately 17 mm with a total height of the shaped piece 4 of 80 mm and a width e of the plate-like web 31 of that base 7 of likewise approximately 17 mm.
  • each holding pin 5 is provided with an insertion cone 6.
  • four holding pins 5 are fastened to a base 7, two holding pins each lying one behind the other in the viewing direction.
  • the four four holding pins 5 present in the central region of the tubular strut 3 (see FIG. 1) are combined in a molding unit. This enables an even faster assembly.
