METAL FITTING FOR MOUNTING INSULATOR FOR WIRE SUPPORT DEVICE IN TUNNEL

PROBLEM TO BE SOLVED: To provide a metal fitting for mounting an insulator, capable of being shared in wire support devices in two different methods with the different number of insulators, and capable of flexibly dealing with an anchor bolt causing variation in driven positions such as a lock bolt. SOLUTION: The metal fitting 1 for mounting the insulator includes: a base fitting 2 having an insulator connection part 6; and a pair of anchor bolts 3 fixed on a ceiling surface of a tunnel T on both sides in an extension direction of the wire. The base fitting 2 includes bolt hole rows 4, 5 for inserting the anchor bolts 3 on both sides. The plurality of bolt holes 4a, 5a comprising the respective bolt hole rows 4, 5 are provided at a mutual interval in the extension direction of the wire. The one bolt hole 4a is long in the extension orthogonal direction of the wire. The other bolt hole 5a is long in the extension orthogonal direction of the wire. The base fitting 2 includes three insulator connection parts 6 arranged in parallel with mutual spaces in the extension direction of the wire between the bolt holes 4a, 5a.
