Claims

[Scope of utility model registration request]

The ends of the bridge girder or the ends of the bridge girder and the abutment are installed at intervals, and between these ends, a pair of steel joint members having tips that can be engaged with each other are installed with a gap between them. A bridge surface expansion/contraction characterized in that a stretchable elastic body is attached to the steel joint member to cover between the ends, and this elastic body is formed with at least one stretchable part capable of absorbing deformation due to expansion and contraction.
