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 (1). A steel-structured bent (2) comprises a vertical beam (9) that can be anchored by support members (3, 4) to the upper surface of the bridge. The vertical beam (9) extends to a distance above the upper surface (11) of the bridge. An upper horizontal beam (12) is rigidly secured to the upper end of the vertical beam (9) and the horizontal beam (12) extends substantially transversely relative to the longitudinal direction of the bridge and over the edge of the bridge. A vertical column (15) is secured to the end of the upper horizontal beam (12). The lowerend of the vertical column (15) extends down from the edge of the bridge. A lower horizontal beam (16) is secured to the vertical column (15) and extends in alignment with the upper horizontal beam. The lower horizontal beam (16) comprises a first beam portion (17) extending from the vertical column (15) to a distance below the bridge so that mould walls (5, 6) can be fitted onto the first beam portion (17), and a second beam portion (18) extending from the vertical column (15) to an opposite direction relative to the first beam portion (17) and supporting an access bridge (8). A longitudinally adjustable support bar (19) is pivotally connected at one end to the first beam portion (17) and at the other end is supportable against the lower surface of the bridge.
