Definitions

  • the present invention relates to a tubular scaffolding system, in particular for scaffolding, with vertical tubular scaffolding stems which are provided at regular intervals with disk-shaped metal rosettes arranged concentrically to them and firmly connected to them, which surround the tubular scaffolding stems in a flange-like manner and are provided with openings, four of which first openings provided in the flange-like rosette have a longitudinal oval shape and are arranged such that their longitudinal planes intersect at a right angle in the longitudinal central axis of the scaffold post, a second opening is arranged between two of the longitudinal oval first openings, the horizontal or diagonal Scaffolding elements in each of their frontal areas
  • a wedge-head element which has an outwardly opening slot which corresponds at least to the thickness of the flange-like rosettes of the vertical scaffolding stems and is in each case provided with a continuous opening which extends perpendicularly to the central plane of the slot.
  • the present invention is based on the object or the technical problem of specifying an improved tubular scaffold system which ensures the previous advantages of easy assembly or disassembly of an economical manufacture and a high load capacity, the economic use of which is increased and in which the ease of handling during assembly continues is improved.
  • tubular scaffolding system according to the invention is given by the features of dependent claim 1.
  • Advantageous refinements and developments are the subject of the dependent claims.
  • the tubular scaffold system according to the invention is accordingly characterized in that an expanding recess is provided on each of the essentially radial side edges of the first opening, as a result of which the web width between the recess and the second opening is reduced, such that the originally minimal web width between the first Breakthrough and the second breakthrough is not fallen below.
  • a particularly advantageous embodiment is characterized in that the wedge, as a protection against loss, has protrusion units arranged transversely to the longitudinal planes in its end region guided through the opening, and the recesses are arranged at the level of these protrusion units when viewed in a plan view.
  • the embodiment according to the invention ensures more uniform utilization of the rosette with regard to the loads to be removed.
  • a particularly preferred embodiment is characterized in that the recess has a part-circular contour.
  • the rosette is preferably made of a steel, for example S 235 or S 355, with a defined increased yield strength.
  • FIG. 1 schematic side view of a tubular scaffold system in the connection area of a rosette with a horizontal scaffold element with a wedge lock connection
  • FIG. 2 shows a schematic section through the arrangement of FIG. 1 along section A - A and
  • a flange-like rosette 14 is shown in a top view with connection of a horizontal scaffold element 22 with a wedge head 30.
  • the inner diameter of the rosette 14 is selected such that it can be connected to the tubular vertical scaffold stem 12 without difficulty, for example by welding.
  • Scaffold element 12 attached rosette 14 are provided with oval first openings 18. These are arranged in such a way that their longitudinal planes, the sections of which are represented by the dash-dotted lines x and y with the plane of the drawing, intersect in the longitudinal central axis A of the vertical scaffold post 12.
  • the longitudinal oval first openings 18 are blunted at their ends pointing away from the central axis A and pointing towards the central axis A and delimited by flat surfaces, the ovalization increasing towards the central axis A. It is also possible to provide other surfaces curved in the manner of a cylinder jacket, the cylinder axis of which coincides with the longitudinal axis 16 of the framework element 12.
  • Breakthroughs 20 arranged. These are each bounded in the direction towards the longitudinal oval first openings 18 by flat surfaces, while their boundary surfaces running parallel to the edge of the flange-like rosette 14 are formed by cylinder jacket cutouts, the cylinder axis of which is also identical to the longitudinal axis 16 of the framework element 12.
  • the dimensions u of the first openings 18 of the second openings 20 in radial Direction are the same.
  • the dimensions V of the second openings 20 are kept significantly larger than those of the first openings.
  • a Keilkop element 30 connected in the respective end area of the elements 22, which has a slot 24 open towards the rosette 14, the thickness of which is slightly larger than the thickness of the rosette 14, so that the wedge head element 30 can be easily pushed onto the rosette 14.
  • a wedge 34 is present in a through opening 32 arranged vertically to the slot 24, which is thereby captively arranged on the wedge head element 30, in which in its lower end region in the exemplary embodiment it has projection elements 26 which are designed as blind rivets and which extend perpendicular to extend the planes x, y.
  • the security against loss is ensured by the continuous opening 32 having an inwardly projecting stop 36 on both sides, so that the opening 32 narrows to a dimension that is smaller than the outer dimension of the wedge 34 with protrusion elements 26.
  • the wedge head element 30 is pushed onto the rosette 14 in such a way that the through opening 32 of the wedge head unit 30 coincides with the first opening 18 of the rosette 14. In this state, the wedge 34 is pulled out upwards, limited by the stop 36. As soon as the wedge head unit is pushed onto the rosette 14, the wedge 34 is simply knocked down by means of a hammer blow, whereby the wedge head element 30 and thus also the scaffold element 22 is supported in a clamped manner on the rosette 14 or the scaffold element 22 - via the end faces of the wedge head 30.
  • the first breakthroughs 18 now have a special feature according to the invention, in that they have recesses 38 with a part-circular outer contour in the essentially radially extending longitudinal oval side edge region of the first breakthroughs 18.
  • the recesses 38 are formed in the first openings 18 such that the distance A from the respective second opening 20 is kept such that it does not fall below the previous smallest distance AI between the first opening 18 and the second opening 20.
  • the geometry of the first opening 18 in connection with the recesses 38 is shown in more detail in FIG. 3.
  • FIG. 3 also shows a projection unit 26 designed as a blind rivet, the blind rivet formation on the opposite head side of the blind rivet 26 having not yet been completed.
  • the wedge 34 is already inserted into the through opening 32 of the wedge head element 30. Then the blind rivet is struck and as a result the wedge 34 is captively present on the wedge head element 30.
  • the geometric changes made to the first opening 18 by the recesses 38 on both sides can be represented as follows.
  • the maximum width B of the first opening 18 in connection with the additional recesses 38 is in the present Embodiment increased to approximately 18 mm (millimeters).
  • the point of the maximum width B is offset from the inner edge contour 40 of the first opening 18 by the dimension C, with the dimension C assuming the value of approximately 8 mm (millimeters) in the specific exemplary embodiment.

Abstract

L'invention concerne un système d'échafaudage tubulaire (10), notamment pour échafaudages, comportant des montants (12) tubulaires verticaux, munis d'éléments d'ancrage ronds (14) métalliques sous forme de disques, disposés de manière concentrique à intervalles réguliers par rapport auxdits montants et solidarisés de manière fixe avec eux. Ces disques entourent les montants (12) tubulaires à la manière de collets et sont munis de passages (18,20). Ce système d'échafaudage tubulaire se caractérise en ce qu'il est prévu à chacune des arêtes latérales s'étendant sensiblement dans le sens radial du premier passage (18), une cavité (38) s'élargissant. La largeur d'entretoise entre ladite cavité (38) et le second passage (20) est réduite, de manière que la largeur d'entretoise minimale initiale ne soit pas dépassée entre le premier passage (18) et le second passage (20).
