PURPOSE:To enhance workability in the fixing work of coil while protecting a coil against damage due to thermal expansion after fixing by inserting a guide pin into an insert and then into a hole of the coil thereby confirming that the insert and the hole of the coil are located at predetermined corresponding positions. CONSTITUTION:Guide pins 20 are inserted into inserts 11 embedded in a concrete panel 3 only at selected points. A levitation coil 7 is then lifted by means of a crane and each guide pin 20 is inserted, while being fitted to a spacer, into a selected hole 9 of the levitation coil 7. Correct location of the insert 11 and the hole of the levitation coil can be checked using the spacer. After checking the correct location, bolts 10 are inserted into the holes 9 inserted with no guide pin 20 and screwed to the insert 11 thus fixing the levitation coil 7 temporarily to the concrete panel 3. |
