To provide a reinforcing structure of a part for connecting a joint plate of a steel or composite segment and a main girder, wherein the joint plate and the main girder uniformly resist a load by restraining the joint plate and the main girder from being subjected to out-of-plane deformation due to a tensile or bending load acting on a joint part, in an iron-based segment structure as a structure for connecting segments or rings together by means of a bolt or a wedge-shaped joint.
The C-shaped cross-section reinforcing member 5 is longitudinally mounted on the inside of a steel shell of the joint plate 2 or the main girder 1 in such a manner as to cover a connecting member for connecting the joint plates 2 or the main girders 1 together. Channel steel is used for the reinforcing member 5.
