Definitions

  • the invention relates to a scaffold element with parallel spaced tubes and connected by transverse tube struts, the tube struts are equipped with holding devices for fastening or fixing planks, planks or other supplementary elements.
  • the tubes are usually provided at one end with plug-in bolts for plugging together with other scaffolding elements, their tube struts attached near the tube ends.
  • scaffolding for several levels can be built one above the other and for larger form lengths by simply plugging these individual elements together and connecting them together.
  • Auxiliary or holding devices are provided in order to attach railings and other protective devices in addition to the planks or planks for accessing the individual scaffolding levels.
  • upwardly directed retaining pins are welded to the transverse pipe struts - round or angular cross-section, but preferably only to the upper transverse pipe strut. These engage when the planks are placed in the prepared holes provided there, so that these planks or planks are displaceably fixed both in the longitudinal and in the transverse direction.
  • 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 demolition.
  • the transverse tube struts are provided with at least two retaining pins forming a common shaped piece, which fits the tube strut in question at least on its upper side and then on both sides and with it - possibly unsolvable by a weld seam - connected is.
  • the shaped piece - for whose design protection is claimed independently - consists of the parallel retaining pin and a cross-sectionally gutter-like base piece, the gutter opening facing the tubular strut.
  • the transverse tube strut can have a rectangular or round cross-section and the shaped piece with the holding pins has a correspondingly shaped cutout which closely surrounds the tube strut.
  • the molded part completely or partially surrounding the tubular strut is 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 retaining pins of the shaped piece are - at least partially - of round cross-section and have a diameter between 15 and 20 mm and a free length between 30 and 60 mm, and further that the retaining pins on both sides of the Pipe brace are arranged at a distance between 30 and 60 mm from each other.
  • 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 screed.
  • the planks lie on a web of the shaped piece and over this the transverse tube strut.
  • four holding pins connected to a single or two separate shaped pieces are fastened to a tubular 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 shaped piece. It has also proven to be advantageous to attach two pairs of retaining pins 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 screed plane or into the cross-section of the transverse pipe strut via the coherent and form-fitting unit shaped part / 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 placing planks 10 on the pipe strut 3, engage in holes prepared there - for reasons of clarity in the drawing - not recognizable - so that the planks 10 both in transverse and are set in the longitudinal direction.
  • 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 or Planek 10.
  • FIG. 3 A fitting 4 with two holding pins 5 and a cross-sectionally C-shaped base piece 7 can be seen in FIG. 3.
  • This shaped piece 4 lies with its fuselage piece 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 piece 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 shaped piece 4, 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.
