PURPOSE: A continuous bridge of a gerber type is provided to secure durability against actuating force by forming joints on the top end of bridge posts. CONSTITUTION: A continuous bridge of a gerber type comprises an intermediate span(120), outer spans(130), and joints(140). The intermediate span is supported by bridge posts(110). The outer spans are respectively located in left and right sides of the intermediate span. The intermediate span is longer than the outer spans. The joints are located in both top ends of the bridge posts, and connect the intermediate span and the outer spans. Steel plates are respectively arranged in the joints to cover end parts of the intermediate span and the outer spans, and integrally coupled with the intermediate span and the outer spans by stud bolts. |
