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.

Bridge expansion device "MM-JOINT・DSII type"

The construction time is short due to the simple structure! A joint that does not damage the floor slab.

The "MM-JOINT・DSII type" is a simple and highly durable bridge expansion joint composed of a special binder, DS aggregate as the main material, secondary water stop devices, gap plates, and pins. Since it is an asphalt-based expansion joint similar to the existing coating, it provides a comfortable experience during passage, suppressing noise and vibration for good drivability. Compared to conventional butt joints, the construction cost is lower, and partial repairs with the same material can be easily performed regardless of the extent of damage, resulting in significantly reduced running costs. 【Features】 ■ Excellent economy and durability ■ Comfortable drivability ■ High waterproofing performance ■ Easy construction *For more details, please refer to the PDF document or feel free to contact us.
