This leads to an increased installation effort and a large depth of concrete wall formwork, which is a hindrance in particular in a small space.
  • the EP 1 321 601 A1 discloses a generic cross bar. In one end region of the transverse bar, the transverse bar is fastened with a bolt passed through a slot on a longitudinal bar of the concrete circular formwork, and in another end area the transverse bar is fastened with a further bolt passed through a round hole on a second longitudinal bar.
