Description

  The present invention relates to a method for installing a body to be fastened to a foundation, and in particular, to secure an adjustment margin almost evenly around a bolt that fastens a body to be fastened (guideway side wall) of a magnetic levitation system to the foundation. It is related with the installation method to the roadbed of the guideway side wall which can do.

  FIG. 6 is a schematic diagram showing a method of arranging a conventional fastened body on the basis.

  First, as shown in FIG. 6A, a hole 102 for fixing an anchor bolt to the foundation 101 is formed.

  Next, as shown in FIG. 6 (b), anchor bolts 103 are implanted in the holes 102.

  Next, as shown in FIG.6 (c), the to-be-fastened body 104 is fixed. That is, the anchor bolt 103 installed is passed through the fastening hole 105 provided in the fastened body 104 and fastened with the nut 106, and the fastened body 104 is fixed to the foundation 101.

  FIG. 7 is a schematic view showing an example of such a conventional magnetically levitated railway guideway, and FIG. 8 is an enlarged cross-sectional view of part A of FIG. 7 (see Patent Document 1 below).

  In these drawings, 201 is a guideway, 202 is a roadbed, 203 is an anchor bolt, 204 is a guideway side wall, 205 is a mounting portion of a leg of the guideway side wall, 206 is a through hole, and 207 is a biased part having a spherical core. A core spacer, 211 is a floating prevention plate, 212 is a thick washer, 213 and 214 are spring washers, 215 is a nut, 221 and 221 'are first eccentric through holes, 222 is a spherical core, and 223 is a second It is an eccentric through hole.

Here, in the conventional method of installing the guideway side wall on the roadbed, the roadbed 202 is previously provided in the through hole 206 of the leg mounting portion 205 of the guideway side wall 204 via the eccentric spacer 207 having the spherical core 222. A guideway side wall 204 as a body to be fastened is fixed to the roadbed 202 by passing through and fixing the anchor bolt 203 implanted in the base.

  However, in the above-described conventional method of installing the guideway side wall on the roadbed, it is very difficult to secure an adjustment margin substantially evenly around the anchor that fastens the guideway side wall to the foundation. That is, as described above, conventionally, before installing the guideway side wall, it is necessary to install (embed) the anchor bolt at the position as designed for the roadbed. However, a construction error occurs at the time of installation of the anchor bolt. Here, a single guideway side wall is fastened with a plurality of anchor bolts.

  Next, the side wall of the guideway is installed at the position as designed, but here too, construction errors occur. As a result, there is a problem that the position of the anchor bolt in the fastening hole on the side wall of the guideway varies.

  Next, another method for attaching the conventional guideway side wall to the roadbed will be described.

  FIG. 9 is a schematic view showing another example of a conventional method for attaching the side wall of the guideway to the roadbed, and FIG. 10 is a plan view showing the position of the anchor bolt as viewed from the fastening hole of the guideway side wall. Here, the case where a single guideway side wall is fastened with six anchor bolts will be described.

  As shown in these drawings, an anchor 302 having a female screw 303 formed therein is implanted in the roadbed 301 by the method described above. After the guideway side wall 304 is installed at the design position, the bolt 306 formed with the male screw 305 to which the washer 308 is attached is inserted from above the fastening hole 305 of the guideway side wall 304, and the anchor formed with the female screw 303 is formed. The guideway side wall 304 is fixed onto the roadbed 301 by being screwed to 302. Also in this case, due to the installation error of the implanted anchor 302 and the installation error of the guideway side wall 304, the center of the fastening hole 305 provided in the guideway side wall 304 and the position of the anchor 302 are shifted as shown in FIG. There was a problem that.

  Particularly, when the position of the guideway side wall 304 is adjusted, as shown in FIG. 10, if the position of the anchor 302 in the fastening hole 305 is varied, the position adjustment of the guideway side wall 304 becomes difficult. was there.

That is, the problem of the present invention is summarized as follows:
(1) An error occurs at the time of anchor installation.

  (2) An error occurs even when the side wall is installed.

  (3) The above two errors compete, and the position of the bolt in the fastening hole varies.

  (4) As a result, the side wall adjustment margin cannot be secured as expected in the design. That is, the adjustment direction and adjustment amount of the side wall are restricted.

  In view of the above situation, the present invention can secure an adjustment margin almost evenly around the bolt that fastens the fastened body (guideway side wall) to the foundation, and can smoothly perform the adjustment work after installation. It aims at providing the installation method to the foundation of the to-be-fastened body which can be done.
