SCAFFOLD ARRANGEMENT AND METHOD FOR REPAIRING THE EDGE STRUCTURE OF A CONCRETE BRIDGE

摘要

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. The lower horizontal beam comprises a first beam portion extending from the vertical column to a distance below the bridge so that mold walls can be fitted onto the first beam portion, and a second beam portion extending from the vertical column to an opposite direction relative to the first beam portion and supporting an access bridge. A longitudinally adjustable support bar is pivotally connected at one end to the first beam portion and at the other end is supportable against the lower surface of the bridge.
