강핑거조인트 (FJ-B Type)

Finger Joint (FJ-B Type)

It is mainly used for medium and large scale bridges with an extension of 120mm or more, and the running surface is composed of a finger-type steel with no discontinuity, which is excellent in running and noise reduction effect.
In addition, finger plate is fixed to the block-out part in the form of a tie-bar, which is economically superior to general hoop type.

Finger Joint (FJ-H Type)

It is mainly used for medium and large scale bridges with an extension of 120mm or more, and the running surface is composed of a finger-type steel with no discontinuity, which is excellent in running and noise reduction effect.
When applied to skew bridges, curved bridges and bridges with a big slope, a sufficient consideration should be given to the interference of finger plates.
