Title:
ANCHORING METHOD AND APPARATUS IN A PRESTRESS REINFORCEMENT
Document Type and Number:
WIPO Patent Application WO1999057390
Kind Code:
A3
Abstract:
Anchoring method and apparatus of an end bearing support type in an external prestress reinforcement for repair and reinforcement of a concrete structure which has been severely damaged, for example, a crack generated because a concrete structure such as a bridge or a pier bends or sags is described. A rib plate (60) is provided on an extension line of an end plate (69) and welded to the end plate (69) so that the concrete contacting the end plate (69) located at the end portion of a girder (68) can bear the tension of an external steel wire (67). Thus, since a small number of short anchor bolts (63) are used, damage to the original structure can be avoided. Load bearing capacity increases by securing the length of welding at the end portion. Also, the possibility of damage by the stress concentrated at the corner portion between the anchoring plate (61) and the end plate (69) can be reduced.
