In the first alternative, each extension piece has two projections extending away from one another on its upper and lower sides, offset from one another.
  • Each handrail has two equal handrail ends extending in opposite directions away from one another.
  • Each end of the handrail is designed as a continuously circumferential tab which has a rectangular opening.
  • the opening is designed as an elongated hole which, viewed in a direction parallel to the longitudinal axis of the balusters, has a length and a width perpendicular thereto with a transverse dimension that is smaller than the length of the opening.
  • the transverse dimension of the opening is chosen so that the handrail can be threaded onto the respective extension piece with alternating pivoting movements.

However, this vertical frame is not able to prevent the scaffold builder from entering the scaffolding floor of a scaffolding bay that has not yet been provided with fall protection. In this respect, the method used there for an early installation of the fall protection does not meet the high safety requirements. Incidentally, the method already described there for the early installation of the fall protection devices is correspondingly complex and impractical. Although this vertical frame also contains vertical supports, neither of these supports is a single support. Viewed in a detached form from the H-shaped vertical frame, one of the supports has the features a), b), partially d), e), partially h), i), k), m), and o) of claim 1 .

  • the scaffold erector To set up a leading railing, the scaffold erector must manually set the H-shaped scaffolding frame together with a railing device detachably attached to it upwards. It has been shown, however, that this is not possible for the scaffold builder or only with great effort and is associated with corresponding safety risks.
  • one of the two supports has features a) to v).
