  • Patent number: 8136191
    Abstract: A scaffold arrangement for repairing the edge structure of a concrete bridge. A steel-structured bent comprises a vertical beam that can be anchored by support members to the upper surface of the bridge. The vertical beam extends to a distance above the upper surface of the bridge. An upper horizontal beam is rigidly secured to the upper end of the vertical beam and the horizontal beam extends substantially transversely relative to the longitudinal direction of the bridge and over the edge of the bridge. A vertical column is secured to the end of the upper horizontal beam. The lower end of the vertical column extends down from the edge of the bridge. A lower horizontal beam is secured to the vertical column and extends in alignment with the upper horizontal beam.
