Outer cables disposed in a box girder in the longitudinal direction of a box girder bridge to prestress the box girder each have a transparent sheath made of a transparent polyethylene resin, vinyl chloride resin, polypropylene resin or the like, thereby allowing the grouting condition in the sheath to be inspected reliably and easily. If a colored grout is filled, the filling condition can be inspected even more reliably and easily. In addition, it is possible to readily find a portion left unfilled after the grout has hardened and to refill it for repairing by using openings for injection and ejection made at each side of the void left.

Transparent protective tube for external cable

PC steel stranded wire connection structure and construction method thereof

A bridge cable fixing structure, including a fixing plate having multiple cylindrical insertion holes and cylindrical fixing grips corresponding to the insertion holes, each fixing grip being attached to an end of a twisted steel wire. The fixing grips are positioned in the insertion holes on a compression side of the fixing structure, such that the twisted steel wires extend from a tensile side of the fixing structure. When a load is applied to the twisted steel wires attached to the fixing grips, the fixing plate deforms toward the tensile side, compressing the insertion holes against the fixing grips.
