。FIG. 6 shows a state in which the first layer propulsion coil 6a, the second layer propulsion coil 7a, and the side wall floating guide coil 8a are attached to the track 5a. However, some of the side wall levitation guide coils 8a are omitted so that the first layer propulsion coil 6a and second layer propulsion coil 7a installed inside can be seen. These propulsion coils 6a, 7a and side wall levitation guide coil 8a are fixed to bolts that are protrudingly installed at predetermined positions on the track 5a.

６ａ”ｄが配置されるが、これには以下の理由がある。The installation 7a shows a cross section of the part, and the coil installation is the propulsion coil installed protruding from the track 5a.
-12, the mounting hole 1 provided on the first layer propulsion coil 6a
3 and the second layer propulsion coil 7a are installed in hole 1.
4 and tighten the nut 15 with the specified torque,
The propulsion coils 6a, 7a are attached to the track 5a. At this time, the coil is installed on track 5a.
There is an adjustment space 1 between the and the first layer propulsion coil 6a.
6a"d is placed for the following reasons.

距１１１Ｌ）、、 Ｌ２ （第５図参照）を所定の値に
維持できない為である。In other words, since the coil mounting track 5a is made of concrete, its surface accuracy is very poor compared to a machined product, and if the propulsion coil 6a is directly attached to the coil mounting track 5a, the propulsion coil 6a, This is because the distance 111L), L2 (see FIG. 5) between the center of the coil 7a and the center of the coil of the superconducting magnet 2a of the superconducting magnetic levitation vehicle cannot be maintained at a predetermined value.
また、表面に凹凸のあるコイル取付は軌道５ａに直接推
進コイル６ａを取付ける事は取付は時に局部的に大きな
応力が発生し、強度的にも好ましくない。In addition, when installing a coil with an uneven surface, it is not preferable to directly install the propulsion coil 6a on the track 5a because large stress may be generated locally during installation, which is not preferable in terms of strength.
また、調整スペーサ１６ａ−ｄを介して推進コイル６ａ

部に高゛い応力が発生し、最悪の場合には破損に至る。Further, the propulsion coil 6a is connected via the adjustment spacers 16a to 16d.
, 7a, it is necessary to pay sufficient attention to the dimension adjustment. For example, in the case of the example shown in Figure 6,
The propulsion coils 6a and 7a are installed in 4 locations, and the coils are installed on the track 5a.
Although it can be installed at any location, the adjustment spacer 1
．． There must be no gap between 6a=d and the first layer propulsion coil 6a. If the nut 15 is tightened while there is a gap, the propulsion coils 6a, 7a will be deformed by that gap when installed, and a high stress will be generated inside the propulsion coils 6a, 7a. may lead to damage.
この為、推進コイル６ａ。For this reason, the propulsion coil 6a.

所により異なる事になる。In order to adjust the dimensions so that there are no gaps at all the mounting locations of 7a, the thickness of the Ill spacer 16ad will vary depending on the mounting location.

は部で異なる事になる。FIG. 8 shows part B in FIG. 6, that is, the side wall floating guide coil 8.
The mounting a shows a cross section of the part, and the coil mounting is a side wall levitation guide coil installed protruding from the track 5a.The side wall levitation guide coil 8a is mounted with a bolt 17. By tightening 19 with a predetermined 1 torque, the side wall levitation guide coil 8a can be installed on the track 5a.
The structure is such that it can be installed on the At this time, the adjustment space 20a□d is placed between the track 5a and the side wall floating guide coil 8a for installing the coil, but the reason for this is that the side wall floating guide coil 8
The distances 1 and 3 (see Figure 4) between the center of the coil a and the coil center of the superconducting magnet 2a of the superconducting magnetic levitation vehicle are maintained at predetermined values, and the dimensions are carefully selected to prevent high stress from occurring internally during installation. This is to perform fine adjustment. For this reason, the thickness of the adjustment spacer 20a=d differs depending on where the side wall floating guide coil 8a is attached.

が必要になっているが、現在はこれという案はどこから
も提案されていない。(Problem to be Solved by the Invention) As described above, in the conventional method of mounting the ground coil, the coil center of the ground coil and the superconducting magnet 2a of the superconducting magnetic levitation vehicle are
In order to maintain the distance from the center of the coil at a predetermined value, and to make fine adjustments to the dimensions so as not to generate high internal stress during installation, each installation uses adjustment spacers 16 with different thicknesses.
It was necessary to use a-d, 20a-d. The track of the superconducting magnetic levitation vehicle between Tokyo and Osaka, which is currently taking shape, will require millions of ground coils, and the installation of each individual coil will require adjustment spacers 16a-d, 20a according to the Tokyo Metropolitan Ordinance.
Performing fine WR adjustment using -d significantly increases the cost and time of the entire superconducting magnetic levitation vehicle system, and a new method is required to replace the method of installing ground coils using adjustment spacers. This idea has not been proposed anywhere.

、内部に発生する応力を必要最少限とする事ができる。After the hardening resin 22 is completely hardened, the nut 19 is tightened to a predetermined torque. At this time, curable resin 2
Since the coil 2 is completely hardened, its deformation is a minute value within the elastic range, and the side wall floating guide coil 8a is tightened to a predetermined torque and the coil is attached to the track 5a. In addition, when tightening the nut 19 to a predetermined torque, the side wall floating guide coil 8a and the hardening resin 2
2 is maintained at zero, there is no unreasonable deformation of the side wall floating guide coil 8a that would occur if there is a gap, and the stress generated inside can be minimized.
