  • Patent number: 4615063
    Abstract: An anchoring rod extends vertically through a hollow box girder underlying a suspension bridge or suspended walkway. The anchoring rod is connected at its upper end to a suspension cable and is provided at its lower end with a stop member which can be tightened against the lower wall of the girder. The opening in the lower wall of the girder through which the anchoring rod extends is larger than the opening in the upper wall of the girder, and a tubular, load-bearing sleeve is carried on the anchoring rod through the lower wall opening. The tubular sleeve is sized so that the upper end abuts against the inner surface of the upper wall of the girder and the lower end abuts against the stop member when the stop member is tightened against the lower wall of the girder.
