Adjustable formwork and climbing system for twisted walls
The new County Hall in Antwerp is a building with 8 completely twisted levels.
The outside walls of these floors lean back- or forwards. All concrete used is white and the inside of the building needs to be fair-faced. For this purpose, Construx designed and manufactured a full steel adjustable and twistable formwork without tie-bars through the wall and of which the inside panels have a stainless steel facing, in order to avoid rust stains.
Technical specifications:
- 12 internal panels 7200mm x 4100mm
- 4 external panels 7200mm x 4100mm
- 12 pneumatic vibrators per internal panel
- 3 straight corners
- 4 adjustable twisted corners
- 16 adjustable window forms
- All cut to measure plywood for the windows of the 8 twisted levels
- 2 set-up frames for the window forms
- Crane lifting hook for the panels
- Crane lifting hook for the window forms
- Adjustable climbing frames, 3m and 3,5m wide
