PROBLEM TO BE SOLVED: To reduce a load applied to a segment body even if a pushing pressure applied from a joint to a segment is enlarged in a joint structure of the segments. SOLUTION: A joint through hole 1c is provided between segments opposed in a joining surface 1d, a bolt boxes 1b are provided in its both ends, and the segments 1 are joined to each other by the joint 2 fastening a nut 2b to a through bolt 2a inserted into the joint through hole 1c. A reinforcement 3 and a bow-shaped fixture 4 are provided between the bolt box 1b and the joining surface 1d and the bow-shaped fixture 4 has its end part welded to the reinforcement 3. When the nut 2b is fastened, the pushing pressure is applied to the bow-shaped fixture 4, however, the bow-shaped fixture 4 is reinforced by a tensile reaction of the reinforcement 3, so that the pushing pressure is dispersed via the bow-shaped fixture 4 and transmitted to the segment body 1a.
