SEGMENT ASSEMBLY STRUCTURE

To provide a segment assembly structure which can lighten the work load of a constructor in the work for assembling hexagonal segments.SOLUTION: A segment assembly structure 10 comprises a plurality of hexagonal segments 1 and couplers 5, 6 that connect multiple segments 1 with each other. Each of the segments 1 comprises a pair of mutually opposing side faces 1a, and a pair of V-shaped oblique end face couples 1c formed at both ends of the side end faces 1a. Each of the oblique end face couples 1c comprises two oblique end faces 1b that incline from each other. The couplers 5, 6 consist of a first coupler 5 which connects segments 1 that are adjacently arranged in the peripheral direction of a cylindrical wall body with their oblique end faces 1b butting against each other, and a second coupler 6 which connects segments 1 that are adjacently arranged in the axial direction of the cylindrical wall body with their side end faces 1a butting against each other.SELECTED DRAWING: Figure 1 【課題】六角形状のセグメントを組み付ける作業における施工者の負担を軽減できるセグメントの組立構造を提供する。【解決手段】セグメントの組立構造１０は、複数の六角形状のセグメント１と、セグメント１どうしを連結する継手５，６と、を備える。セグメント１は、対向する一対の側端面１ａと、側端面１ａの両端に形成された一対のＶ字形状の傾斜端面対１ｃとを備える。傾斜端面対１ｃは、互いに傾斜する２つの傾斜端面１ｂを有する。継手５，６は、筒状壁体の周方向に隣り合うセグメント１を、傾斜端面１ｂどうしを突き合わせて連結する第１継手５と、筒状壁体の軸線方向に隣り合うセグメント１を、側端面１ａどうしを突き合わせて連結する第２継手６と、を含む。【選択図】図１
