【Expansion Device】Noise issues from the expansion device! What is the cause? What is the inspection method?
A clear explanation of the damage caused by noise and the causes of noise generation! We will also introduce inspection methods.
Have you ever heard a "thud" sound coming from above when passing under a bridge? It might be the sound of a vehicle passing over an expansion joint. When the sound is small, people tend not to pay much attention to it, but when it becomes loud, it can be a significant source of stress for those living nearby. At Expansion Joint Navi, we provide information on "causes of noise generation," "noise countermeasures," and "inspection methods," among other topics.

It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
