Title:
SEGMENT JOINING METAL FITTING, SEGMENT, AND METHOD FOR JOINING SEGMENTS
Document Type and Number:
Japanese Patent JP3462065
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently fill each gap between joining metal fittings with a caulking compound.
SOLUTION: A projection 3c of a joining metal fitting 3 inserted into an insert hole 1c provided in the metal fitting at the time of joining hexagonal segments Sa breaks a capsule 5 and extrudes a caulking compound (c) to gaps (g) between joining metal fittings 1, 2, 3 from the hole 1c. The caulking compound (c) is extruded strongly by the projection 3c to the central part in the segment-thickness direction of the gap (g), so that the compound goes uniformly to the whole area of the gap (g) which is therewith choked certainly. The projection 3c inserted into the hole 1c strengthens the joining force of the mutual segments Sa.
