a bridge equipment for the bridge wich elasticity supporter

摘要

The present invention relates to a bridge device of a bridge with high absorption rate of shock vibration and seismic efficiency against earthquakes. In particular, the structure of the elastic bearing is improved so that the elastic bearing breaks when deformation (displacement) occurs during expansion and rotation load. It relates to a bridge scaffolding device having an elastic support that can prevent the thing.;The present invention forms a steel plate 103 installed below the rubber pad 101 of the elastic support 100 to a thickness thicker than the depth of the recess 121 of the lower leg 120, so that the rubber pad is recessed when displacement occurs. It is to provide a bridge device for a bridge having an elastic support that can be prevented from being damaged by interference.
