T he use of a falsework tower does not stop with the assembly of its adjustable heads. By definition, it supports a load, most often prefabricated concrete or cast in place which requires creating a working platform at the top part in order to lay the formwork in collective protection. The “ TOURECHAF ” was desi- gned to respond to this dual function:“Falsework TOWER ” for the load take-up and“ SCAF folding” to allow for the formwork ope- rations and the installation of prefabricated components in collective safety. The CRAB connection fi xed at the head of the standards of the Touréchaf frames is unique. It alone allows a ledger to have a single centre distance, irrespective of standard diameter: 49 mm for scaffolding or 60 mm for the Touréchaf.This technical advantage without equal allows us to use our scaffolding equipment on the Touréchaf and thus simply transform the top of our falsework into a secure working platform. The length of the stirrups welded on the Touréchaf standards with a diameter of 60mm are shorter than those welded on the scaffolding standards with a diameter of 49mm in order to offset the difference in section. The centre distance is retained . The ledgers, diagonal braces and decks of our scaffolding equipment are thus compatible withTouréchaf. It becomes simple to make the connections, the “Z” wind bracings and the decking between towers. Mainly two decking heights between towers are distinguished: In the lower part of the top frame for the fi tting and removal of the conventional formwork: In the highest part of the top frame for the fi tting of prefabricated parts. There is no stirrup at mid-height of the standards of the frames. Indeed, they could generate horizontal forces brought by a diagonal brace for example, which would increase the risks of buckling. This chapter "Scaffolding compatibility" presents: - Towers with more than 4 feet. -Wind bracing. - Towers with extension. - Runs and blocks. - The decking between towers. - Cantilevering. - Different heights and mobile towers.
