JOINT STRUCTURE OF SEGMENT
To provide a joint structure of a segment capable of suppressing a partial opening of a joint surface.SOLUTION: A concave part 11, 11 is respectively formed on each surface of the adjacent cylinder bodies 2, 2, a through hole 17 is formed through end surfaces 4, 3 between bearing surfaces 12, 12 at the end surface 4, 3 side of the concave part 11, 11 respectively, a bolt 21 is inserted in the through hole 17, a nut 22 is provided at an end 21T of the bolt 21 in each of the concave parts 11, 11, and an elastic washer 26 is arranged between the bearing surface 12 and the nut 22. When an opening is created at the upper and lower end surfaces 4, 3, the elastic washer 26 with a low elastic coefficient contracts, and when the opening reaches a predetermined amount, the bolt 21 with a high elastic coefficient deforms, suppressing the opening and creating an opening between other upper and lower end surfaces 4, 3. A sheath pipe 36 preventing entry of a filling material 37 is provided in a periphery of the elastic washer 26, and the periphery of the elastic washer 26 is not restricted by the filling material 37 and can contract.SELECTED DRAWING: Figure 1
【課題】接合面の部分的な目開きを抑制することができるセグメントの継手構造を提供する。【解決手段】隣り合う筒体２，２の表面に凹部１１，１１を形成すると共に、これら凹部１１，１１の端面４，３側の支圧面部１２，１２間に、端面４，３を貫通する貫通孔１７を形成し、貫通孔１７にボルト２１を挿通すると共に、凹部１１，１１内においてボルト２１の端部２１Ｔにナット２２を設け、支圧面部１２とナット２２の間に弾性ワッシャ２６を配置する。上，下端面４，３に目開きが生じると、弾性係数の小さい弾性ワッシャ２６が収縮し、目開きが所定量に達すると、弾性係数の大きなボルト２１に変形が起き、目開きが押えられ、他の上，下端面４，３間において目開きが発生する。また、弾性ワッシャ２６の周囲に充填材３７の侵入を防止する鞘管３６を設けることで、弾性ワッシャ２６の周囲が充填材３７により規制されることがなく、収縮することが可能となる。【選択図】図１
