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.
A climbing scaffolding assembly for in situ casting a reinforced concrete wall in successive superposed layers of variable inclination, said assembly comprising a scaffolding unit of generally inverted U-shaped configuration including a support frame adapted to be disposed to one side of a wall in construction and to bear against the one wall side only, a cantilever member disposed at an end of said support frame for defining headspace above the top of a wall portion previously cast and a movable frame suspended from said cantilever member and generally parallel to and spaced from said support frame, means operatively associated with said movable frame for adjusting the position of said movable frame with respect to said support frame, a first shuttering panel and first set of working catwalks provided on said support frame, a second shuttering panel provided adjacent to said movable frame and a second set of working catwalks provided on said movable frame, said shuttering panels corresonding to opposed sides of a wall portion to be cast, first cooperable means securable to the said one side of a lower portion of a previously cast wall portion and second cooperable means on said support frame cooperable with said first cooperable means and associated with motor means mounted on said support frame for lifting the entire scaffolding unit including said support frame and said movable frame, said cantilever member, said first and second shuttering panels and said first and second sets of catwalks all in unison from a level corresponding to a last-poured layer of concrete to a lever corresponding to the layer of concrete to be poured next.
