<p>PROBLEM TO BE SOLVED: To improve the mechanical strength by a method, wherein spacers are made of continuous glass fiber reinforced resin. SOLUTION: A propulsive coil 8 which is fixed to the inner side of the side wall of a concrete track 7 by spacers 9 consists of a conductor 8a, and its covering 8b which is a molding of epoxy. The spacers 9, made of continuous glass fiber reinforced resin L-SMC, press a propulsive coil 8 against the side wall of a concrete track 7 with fixing means 14 to fix the coil 8. The spacers 9 are fixed to the side wall by inserts 10, buried in the side wall, bolts 11 screwed into the insertes 10, washers 12 and units 13 screwed onto the bolts 11, and the propulsive coil 8 is fixed to the side wall by then with the spacers 9 there between. The continuous glass fiber reinforced resin L-SMC is composed of thermosetting polyester resin and continuous glass fibers which are provided in the polyester resin in whirlpool shapes, so as to be distributed with uniform density and formed into a sheet. The glass fibers are entangled with each other, and the movement at the time of the pressure-heating molding can be blocked.</p> |
