  • the scaffold 20 is formed symmetrically to a longitudinal plane of symmetry 65 contained in the first longitudinal axis 23 and the second longitudinal axis 43 and also symmetrically to a cross-symmetry plane 67 containing the carrier profile longitudinal center 27 of the round tube carrier profile 21. designed. Accordingly, the U-reinforcement profile 22 and thus also the two lateral profile legs 50.1, 50.2 of the U-reinforcement profile 22 extending substantially parallel to one another are symmetrical to the longitudinal plane of symmetry 65 and also symmetrical to the transverse plane of symmetry 67 trained or designed.
  • the two symmetrical to the longitudinal plane of symmetry 65 designed and arranged profile legs 50.1, 50.2 of the U-reinforcement section 22 of the Gerstriegel 20 extend on either side of the longitudinal plane of symmetry 65 and thus on both sides of a perpendicular to the second longitudinal axis 43 formed profile leg axis 51 of the U-reinforcement profile 22 parallel to each other.
  • the two profile legs 50.1, 50.2 of the U-reinforcement profile 22 are laterally offset with their attachment ends 55.1, 55.2 each with respect to the longitudinal plane of symmetry 65 by an equal distance, which half of the transverse spacing 52 and half of the U-gain profile Width 52 corresponds. Therefore sit the profile legs 50.1, 50.2 of the U-reinforcement profile 22 and thus sits the U-reinforcement profile 22 not at the lowest position in the installed position 30 of the round tube carrier profile 21, but from the center 40 of the round tube carrier profile 21 and the longitudinal plane of symmetry 65 offset to both sides.
  • the framework bar 20 has an overall height 71 which corresponds to the sum of the outer diameter 28 of the round tube carrier profile 21 and the effective reinforcing profile height 68.

  • the effective aperture height 70 is reduced from the aperture height 63 by the amount 69 of about 1.04 mm.
  • the U-reinforcement profile 22 is produced by bending, bending and / or profiling on a roller train of a plate-shaped or band-shaped, preferably planar, steel sheet or semifinished steel sheet, not shown in the figures, about a single bending or bending axis.
  • the scaffold 20 provides an advantageous possibility for attachment of, in particular already existing, not shown in the figures accessory components with, in particular standardized, preferably integrated couplings in a longitudinal region of the round tube carrier profile 21, in which also the U-reinforcement profile 22nd extends, and / or for a backup of at least one resting on or on the round tube support section 21, in particular existing scaffold floor 39 against lifting by means of a at the bottom of or the respective scaffold floor 39 relative to this by a transverse, in particular, perpendicular to the working surface of the scaffold floor 39 arranged pivot axis pivotable, not shown in the figures safety bolt.
  • FIG. 5 a stacking arrangement 75 of two scaffolding bars 20 according to the invention is shown, comprising a first scaffold bar 20.1 and a second scaffolding bar 20.2.
  • the first scaffold bars 20.1 and the second scaffolding bars 20.2 have the same design. In other words, the stack arrangement shows two identical scaffold bars 20.
  • stack assembly 75 is the second scaffold 20.2 opposite the first scaffold bar 20.1 rotated by 180 degrees about the first longitudinal axis 23 of the first scaffold tower 20.1 arranged such that, viewed in a cross section perpendicular to the first and second longitudinal axis 23 and 43 of the first scaffold tower 20.1, with the respective base profile 49 of the respective U-reinforcement profile 22 formed or limited ends 76 of the respective U-reinforcement profile 22 in opposite directions away from each other or that the U-reinforcement profile 22 of the first scaffold 20.1 of the round tube support section 21 and the reinforcing profile 22 of the second scaffold 20.2 of the latter Have circular tube carrier profile 21 in opposite directions away.
  • the round tube carrier profile 21 of the second girder 20.2 is located on or on a profile leg 50.1 of the two substantially parallel profile legs 50.1, 50.2 of the U reinforcement profile 22 of the first girder 20.1 and the U reinforcement profile 22 of the second girder 20.2 is included a profile limb 50.1 of its two substantially parallel profile limbs 50.1, 50.2 on or on the round tube carrier profile 21 of the first structural beam 20.1, so that the profile leg axis 51 of the U reinforcement profile 22 of the second structural beam 20.2 and the profile limbs -Axis 51 of the U-reinforcement profile 22 of the first girder 20.1 run approximately parallel (see FIG. 5 ).
