BRIDGE GIRDER, BRIDGE GIRDER STRUCTURAL BODY, AND METHOD FOR CONSTRUCTING BRIDGE GIRDER

PROBLEM TO BE SOLVED: To provide a bridge girder, a bridge girder structural body and a method for constructing the bridge girder facilitating transportation and execution work, shortening a construction period, reducing manufacturing and execution cost and having high rigidity and high durability. SOLUTION: This bridge girder structural body is a hollow bridge girder structural body 9 with an outer peripheral edge part 34 formed of a double wall part 32 composed of a hollow external wall body part 30 and an internal wall body part 31 positioned inside the external wall body part 30, and with a hollow part 35 formed at the center part. A skeleton body 37 is inserted in a space area 36 formed by the external wall body part 30 and internal wall body part 31 of the bridge girder structural body 9.
