Bridge expansion device "N-FC Finger Joint"

Bridge expansion device "N-FC Finger Joint"

A structure designed with consideration for workability during regular inspections from below the bridge and when replacing water-stopping materials after it has been put into service!

The "N-FC Finger Joint" is a bridge expansion device that protects the water-stopping material, which is essential for non-drainage functionality, and prevents early deterioration of bridge girder ends in snowy and cold regions. By adding a fin cover to the underside of the face plate and narrowing the gaps of the comb teeth, the proportion of soil, snow, and ice that enters the gaps and reaches the water-stopping material can be reduced to below 15% even at the lowest temperatures (-20°C), thereby preventing the deterioration of the water-stopping material. Additionally, by using water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures, water-stopping performance is ensured. 【Features】 ■ Added fin cover to the underside of the face plate to narrow the gaps of the comb teeth ■ Resists constant wheel loads with only the face plate ■ Confirmed fatigue durability of over 50 years through fatigue tests using full-scale specimens ■ Utilizes water-stopping materials that have passed tests based on NEXCO's construction management guidelines for structures ■ Dry water-stopping materials, support brackets, and water-stopping rubber are designed to be detachable from below the girder *For more details, please refer to the PDF document or feel free to contact us.
