In the present embodiment, as shown in FIGS. 1 and 2, each base block 150 has a hole portion 157 that penetrates from the outer side surface 155 to the inner side surface 156.

  The anchor bolt 170 has a J-shaped embedded portion embedded in the base portion 159 and a screw portion protruding linearly from the base portion 159. In the present embodiment, in each foundation block 150, the anchor bolts 170 are arranged in a pair with a predetermined interval in the left-right direction. However, the arrangement of the anchor bolts 170 is not limited to this, and it is sufficient that at least one anchor bolt 170 is provided in each foundation block 150.

In the cross section of each foundation block 150, the shortest distance L ₂ between the inner wall surface 154 of the groove 151 and the anchor bolt 170 is larger than the shortest distance L ₁ between the outer wall surface 152 of the groove 151 and the anchor bolt 170. That is, the rail 160 is located in the groove portion 151 so as to be biased toward the outer wall surface 152 side.

  The rail 160 includes a support part 161 that supports the movable structure 140 by rolling contact with a wheel 191 of a wheel part 190 described later, and a flat base 162 that protrudes from the upper surface of the support part 161.

As shown in FIGS. 1 and 2, the length of the seat portion 122 is adjusted so that the lower end of the seat portion 122 reaches the upper surface of the foundation block 150.

  With the configuration described above, the movable structure 140 expands and contracts when the wheel portion 190 travels on the rail 160 in the front-rear direction indicated by the arrow 10 in FIG.

  When the electric device is assembled in the local assembly house 100 of the electric device, the movable structure 140 is in an extended state as shown in FIG. That is, the space | interval between the frame parts 121 becomes the widest, and it is the state which the sheet | seat part 122 stretched out.

  In this state, the interior of the electric equipment local assembly house 100 is enclosed by the front fixed wall 110, the rear fixed wall 111, the plurality of foundation blocks 150, and the movable structure 140, thereby forming a closed space.

  In addition, in FIG. 1, although it has shown so that the groove part of the foundation block 150 located adjacent to the opening-and-closing door 113 may be exposed, when assembling an electric equipment in the local assembly house 100 of an electric equipment, This portion is blocked by a sheet member or the like. In addition, the sheet | seat part 122 may be provided so that the front surface and the rear surface of the movable structure 140 may also be covered so that the groove part of the foundation block 150 may not be exposed.

  The hole 157 provided in the foundation block 150 is used as an air-conditioning duct or a wiring duct such as a power cable in the on-site assembly house 100 of the electric equipment. Therefore, the hole 157 that is not used is closed by a sheet member or the like.

  Thus, by making the inside of the local assembly house 100 of electrical equipment a closed space, it is possible to prevent the entry of foreign substances such as dust while maintaining the inside of the local assembly house 100 of the electrical equipment at a predetermined temperature and a predetermined humidity. It can be maintained in a clean state.

  On the other hand, large parts that cannot pass through the open / close door 113 and large machines for assembling the electric equipment among the parts constituting the electric equipment are brought into the local assembly house 100 of the electric equipment, or on the local site of the electric equipment. When unloading from the assembly house 100, the movable structure 140 is in a contracted state as shown in FIG. That is, the space | interval between frame parts 121 becomes narrow, and it has been in the state where sheet part 122 was folded up.

  In this state, the front side fixed wall 110 and the movable structure 140 are separated from each other, and the side and upper side are opened on the front side in the field assembly house 100 of the electric equipment. Through this open portion, a large structure is conveyed by a crane or the like.

As described above, the plurality of foundation blocks 150 are placed on an iron plate spread on the surface of land that is not leveled.

  Therefore, as shown in FIG. 6, variations occur in the positions in the height direction of the respective basic blocks 150. Specifically, the unevenness of the land surface, the variation in the thickness of the iron plate 20, the manufacturing error of the foundation block 150 itself, and the like are combined to cause variations in the position of each foundation block 150 in the height direction. In addition, in FIG. 6, the boundary of each iron plate 20 is not illustrated for simplicity.

  In the on-site assembly house 100 of the electric equipment according to the present embodiment, the position in the height direction of the rail 160 is adjusted by the lower nut 180. Therefore, first, as shown in FIGS. 6 and 7, the lower nut 180 is assembled to all the anchor bolts 170. Next, the height of the upper surface of each lower nut 180 is adjusted to be substantially the same.

  Thereafter, the rail 160 is disposed. Specifically, the anchor bolt 170 is inserted into each of the plurality of through holes 162 h provided in the base 162 of the rail 160. Thereafter, the upper nut 181 is assembled to all the anchor bolts 170. By tightening the upper nut 181, the base 162 of the rail 160 is sandwiched between the upper nut 181 and the lower nut 180, and the rail 160 is fixed to the base 159 via the anchor bolt 170.

  FIG. 8 is a plan view showing a state in which the rail is fixed to the foundation block when assembling the on-site assembly house for the electric equipment according to the present embodiment.
