ABSTRACT:
A scaffolding assembly is made up of independent units each of which is fitted with inside and outside shuttering panels. The assembly is particularly suitable for in situ casting of walls in reinforced concrete, in successive layers which may vary in their inclination to the vertical. Each unit includes a support frame which is attached to one surface of the wall in progress and is fitted with one shuttering panel and a first assembly of catwalks. At its upper end it has a cantilever which overhangs the top of the wall, from which is suspended a movable frame substantially parallel to the support frame. The position of the movable frame on the cantilever is adjustable, to vary its distance from the support frame. The movable frame is fitted with the other shuttering panel and with a second catwalk assembly. A lifting system on the support frame co-operates with attachments on the wall to raise the unit. It includes at least two cams on each upright of a support frame which progressively engage the attachments to clamp the support frame in position. This system also includes slidable bearing arms which positively engage the attachments and which are retracted during raising of the unit. The horizontal position of all the catwalks of each catwalk assembly are simultaneously set by a respective levelling system. At least one side of each catwalk assembly is extensible to provide catwalks continuous from one scaffolding unit of the assembly to the next.
