- a formwork reinforcement is used in particular a reinforcing cage made of reinforcing bars.
- concrete is poured into the volume of the formwork. After hardening of the concrete, the formwork side walls are folded away and the precast concrete part of the formwork removed. Then the formwork is cleaned and the next precast concrete part is produced.
- a formwork and a method for producing precise precast concrete parts are known.
- Such precise precast concrete elements are in particular segments that are needed in tunnel construction.
- This formwork is used to produce tubbing in circulation production, wherein the formwork is arranged on a chassis for transporting the formwork on a roadway. Between the formwork and the chassis, a device for compensating for unevenness of the road, in particular a three-point bearing is arranged.
- the formwork a body, on the side walls of the tubbing formwork are movably mounted, comprises, wherein the base body is supported on a support assembly.
- the base body is supported on exactly three support points on the support assembly.
