Definitions

  • the invention relates to a vertical frame made of metal according to the preamble of claim 1.
  • system scaffolds such as the Layher flash scaffolding system, which has been known for many decades and has proven itself in practice.
  • This comprises two vertical stems and two at a height corresponding to the passage height to each other at this permanently fixed cross bar, which are respectively arranged perpendicular to the stems and form together with this a rectangular, closed, vertical frame-setting frame.
  • the upper crossbars are designed as upwardly open U-profiles, can be mounted in the scaffold floor elements via claw units.
  • the lower crossbar may be formed as Heileckholmprofil.
  • the adjusting frames are designed to be pluggable on each other, so that it is possible to build up several scaffoldings.
  • Such system frameworks are for example from the DE 38 07 631 A , of the DE 198 27 284 A1 or the WO 02/066768 A1 of the Applicant become known.
  • Similar, constructed from closed rectangular frame system scaffolds are for example from the DE 31 39 980 C2 , of the CH-PS 439 679 or the DE 87 11 664 U1 known.
  • Other scaffolds that can be built with frames have U-shaped vertical frames that are designed to be open at the bottom.
  • Such frames or frames are for example from the DE-PS 1 434 369 , of the DE 1 677 836 U , of the DE 200 02 371 U1 , of the DE 196 48 488 A1 , of the CH-PS 439 679 , of the CH-PS 457 803 , of the FR-A-2 448 013 , of the DE 100 09 885 A1 (forms the closest prior art) and the U.S. Patent 2,305,563 known.
