Definitions

  • the invention relates to a scaffold tube according to the preamble of claim 1.
  • Scaffolding tubes especially standpipes or railing posts for Scaffolding is usually used when setting up the scaffolding plugged onto each other, the stanchions often also in so-called scaffold frames are integrated.
  • the outer diameter in Essentially the inside diameter of the scaffold tube corresponds, so that the scaffold tube to be arranged above this extension can be plugged on.
  • This extension will for example, by a pressed-in pipe connector Round tube formed.
  • scaffolding with such scaffolding tubes always pipes of the same wall thickness are used to the To ensure a precise fit of the plug connection.
  • the object of the invention is therefore a scaffold tube to propose lighter, thinner walled tubes in Combination with previous scaffold tubes or standpipes can be used while avoiding the disadvantages mentioned above are.
  • one according to the invention is distinguished Scaffold tube characterized in that in which to attach usable end area of the tube one Cross-sectional taper is provided.
  • the Cross-sectional taper made by embossing.
  • the cross-sectional taper is advantageously annular educated.
  • An annular formation of the Cross-sectional tapering results in uniform embossing forces acting on the circumference, so that the impression by means of appropriate stamps from the outside without any further Measures must be taken inside the pipe.
  • the cross-sectional taper is advantageously from the edge of the scaffold tube attached spaced. The remains Outer circumference of the tube in the front contact area receive. In addition, the stamping process itself with one certain distance from the edge of the pipe easier accomplish.
  • the distance of the cross-sectional taper or Guide length, which is the distance of the cross-sectional taper corresponds, is preferably to the desired Tilt stability and / or the desired quality of alignment adapted to the connector.
  • Cross-sectional rejuvenation is conceivable, which extends beyond a certain Distance extends in the axial direction, which in turn extends from the desired tilt stability and / or the desired quality the orientation of the connector results.
  • Basically is such a longitudinally extending cross-sectional taper also conceivable in a ring, but it would also be for this Embodiment in particular rib-shaped impressions that are distributed around the circumference of the scaffold tube, an advantage. Longitudinal ribs, for example, can simultaneously Bending stiffness of the pipe in the area of the plug connection be improved.
  • Such one Insert can, for example, be pressed or fixed be welded.
  • Such an insert causes a certain additional effort in production, it is suitable however, particularly in the use cases where a Increased rigidity in the area of the plug connection it is asked for.
  • Figures 1 and 2 show the lower end of a scaffold tube 1 with an outer diameter A and an inner diameter I.
  • the inner diameter I is due to a Thin-walled embodiment of the scaffold tube 1 larger than the inside diameter of a conventional, thick-walled one Scaffold tube (not shown). This The inside diameter corresponds essentially to that Outside diameter a of a pipe connector 4 (see FIG. 3).
  • annular cross-sectional tapering 2, 3 in the lower Embossed area of the scaffold tube 1.
  • the Cross-sectional tapering 2, 3 are shaped such that their inner diameter i essentially the outer diameter a correspond to the pipe connector 4. This results in First attach the scaffold tube 1 to the tube connector 4 good centering of the attached scaffold tube 1, so that a circumferential contact surface of the front of the Scaffold tube 1 on the scaffold tube underneath is ensured.
  • both cross-sectional tapers 2, 3 are over a distance F apart.
  • This distance F thus defines the guide length from which the quality of the Alignment of the plug connection as well as the tilt stability depends.
  • the appropriate selection of the guide length F can in connection with the manufacturing tolerances of the Inner diameter i of the cross-sectional taper 2, 3 or of the outer diameter a of the connector 4 thus the desired property of the connector with respect to Alignment and tilt stability can be produced.
  • the lowest cross-sectional taper 2 has a height H spaced from the lower edge of the scaffold tube 1. hereby the embossing of the cross-sectional taper 2 becomes essential facilitated. In particular, this can be used in conjunction with the ring-shaped and therefore evenly over the circumference distributed training of cross-sectional tapering Embossing only from the outside of the scaffold tube 1 be made. In particular, here are those for Embossing required forces equally distributed around the circumference.
  • FIG 3 is the use of an inventive Scaffold tube 1 or 1 'in a scaffold frame 5 illustrated.
  • Such scaffolding frames 5 are preferred for used the construction of the narrow side of scaffolding.
  • the Scaffold frame 5 is composed of two standpipes 1, 1 'and two crossbars 6, 6 'together.
  • the two stanchions 1, 1 ' are provided on their top with pipe connectors 4, 4 ', so that, for example, another identical and not closer shown scaffold frame can be plugged on top.
  • the shape according to the invention is not only on standpipes limited by scaffolding. It can be used in all types of Scaffolding elements are used, the use of Pipes of different wall thickness with plug connections Pipe connectors 4 provides, especially for vertical Scaffolding elements, such as vertical frames, vertical supports, etc.
  • vertical Scaffolding elements such as vertical frames, vertical supports, etc.
  • Railing posts on the top level of a Scaffold attached as part of the side protection and attached to the pipe connector 4 of standpipes 1 become.
  • the scaffold tube 7 represents an embodiment with four upper ones Cross-sectional tapering in the form of nose-shaped Imprints 8, 9, 10 and four lower also in the form of nose-shaped impressions 11, 12, 13 present Cross-sectional tapers.
  • the corresponding impressions on the invisible back are in the illustration not recognizable according to FIG. 5.
  • the cross-sectional drawing 6 on the other hand, is the fourth lower impression 14 clearly.
  • the upper impressions 8, 9, 10 and the lower ones Impressions 11, 12, 13, 14 are at a distance F with respect the longitudinal direction of the scaffold tube 7 attached, whereby a corresponding guide length F when plugging on Scaffold tube with a smaller cross section results.
  • the Outside diameter of the pipe to be inserted is given in this embodiment from the distance d opposite nose-shaped impressions, e.g. the Distance between the impressions 11, 13 according to FIG. 6.
  • This embodiment also makes the invention Advantages, i.e. the usability lighter, thinner walled Tubes in combination with previous scaffold tubes or Standpipes avoiding the above Disadvantages achieved.
