Kind Code:
A
Abstract:
To provide a fitting structure of a bridge-suspending cable which can be easily installed with a conventional simple structure.SOLUTION: In a cable 10 for a power or a communication, linked to a road bridge 2, an excess length part 11 bent like a lateral 8-shape in an end part of a first bridge girder 3. Upper end parts 11a and 11b of the excess length part 11 are supported by excess part holding members 12 and 12. Each excess part holding member 12 includes: a cylinder member 15 inserted into the cable 10; and a plurality of connection ropes 16 and 16 for coupling a part of the cylinder member 15 to a support member 14. An annular part 18a on a tip side of a release liner member 18 as a holding release mechanism is engaged to the connection ropes 16 and 16 of each excess part holding member 12, and the annular part on a base side is coupled to a lateral girder 20 on a second bridge girder 4 side. When displacement exceeding a reference value occurs between the first bridge girder 3 and the second bridge girder, a tension occurs in the release liner member 18 to cut each connection rope 16, and holding of the excess part 11 by each excess part holding member 12 is released.SELECTED DRAWING: Figure 1
