Claims

[Scope of utility model registration request]

Among the segments that are connected to each other through joints on the joint end faces to form an annular wall, this is a key segment that is inserted along the axial direction of the wall at the end of assembly, and is used at one end in the longitudinal direction. Consisting of a segment body whose width between the side surfaces is tapered to the other end side, and joint fittings embedded in both end faces in the longitudinal direction of this segment body, respectively,
Further, steps are formed on both side surfaces of the segment main body, each having a joint surface facing the insertion direction of the segment, and a side surface of the segment facing the joint surface is formed on the joint surface of the step. A key segment characterized by having a protruding load-bearing pin inserted into a fitting hole formed in the key segment.
