Title:
SEGMENT CLAMPING MECHANISM
Document Type and Number:
Japanese Patent JP3849188
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the accompanying turn of a bolt surely by simple structure.
SOLUTION: The segment clamping mechanism has fixtures connecting three nuts 4 for clamping housed in the box holes of a segment, and notched holes for housing the fixtures are formed to wall surfaces oppositely faced to a wall surface, to which the boltholes of the box holes are shaped. A pair of approximately rectangular parallelopipeds 8, 8 rotatably bound at one end in the longitudinal direction are used as the fixtures, a connecting means 9 mutually coupling the approximately rectangular parallelopipeds is formed at the other end, recessed sections 10 fast stuck on the half side sections of the nuts 4 for clamping are formed to the mutually faced surfaces 8a, 8a respectively, and rubbers 11 are stuck into the recessed sections 10.
