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, we 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 720cmm x 410cm
- 4 external panels 720cm x 410cm
- 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
Formwork for curved walls with relief
For the Mons railway station, Construx supplies a one-off full steel circular shuttering system with round relief
Both 2 main circular cores and their connecting walls need to be poured on-site. Almost all walls are round, some of which are even round in both directions. All formwork is full steel: steel frame with steel sheeting.
Precast moulds · on-site formwork and scaffolding for viaduct piers
All piers have the same cross-sectional base and rectangular top
Seen the height of the piers varies from 4m to 14m, all vertical ribs have a different inclination.
The 1st stage consists of a viaduct with 34 high piers, poured on-site, after which 2 precast 80T heads are positioned on hydraulic scaffolds. The connection is poured afterwards.
The 2nd stage consists of a viaduct with 14 lower piers. The precast heads are positioned onto a hydraulic scaffold under which the piers are poured.
- Adjustable modular pier formwork
- Hydraulically tiltable and moveable pier head moulds
- Transport yokes for truck and barge
- Internal rebar supports
- External modular rebar scaffolds
- Hydraulic support scaffolds
- Connection form
- Hydraulic frames to hold the heads
