<p>PURPOSE: A finger joint coupling structure for a bridge in which expansion joint concrete is unnecessary is provided to reduce the working time and cost by conveniently replacing a finger joint and a fastening bolt in the upper part of a slab and to construct the structure without expansion joint concrete. CONSTITUTION: A finger joint coupling structure for a bridge in which expansion joint concrete is unnecessary is composed of a pair of base angles(100,100a), a bolt guide(200), an anchor, a pair of finger joints(400,400a), a fastening bolt(600), a fastening nut(700), and a drain board(800). The base angles are fixed to be corresponded to the corresponding edge between slabs of a bridge. The bolt guide is installed in the base angle. The anchor fixes the base angle to the slab. The finger joints are put on the base angles to be corresponded. Plural fingers(410,420) are projected in the finger joints. The fastening bolt and the fastening nut fix the finger joint. The drain board is installed between the finger joints.</p> |
