As the base rail B5 having the opening B6 on one surface, a U-shaped grooved steel (C-type channel) or an H-shaped section steel having an opening B6 formed on the one side surface over the entire length in the longitudinal direction. Alternatively, a square pipe in which the opening B6 is formed at both ends thereof, a square member in which the opening B6 is partially formed only in a part in the longitudinal direction, or the like is used.
As the spacer 33d, a cylindrical spacer having a C-shaped cross section is preferably used so that the spacer 33d can be attached to the screw portion 32b of the support portion 32 after the auxiliary nut 33c is tightened.
In the example shown in FIG. 6, as a base rail B5 having an opening B6 on one surface, a U-shaped grooved steel (C-type channel) in which the opening B6 is formed over the entire length in the longitudinal direction, A square pipe in which the opening B6 is formed is used. A through-hole B7 that is larger than the outer diameter of the threaded portion 32b of the support portion 32 but smaller than the outer diameter of the nut 33b and the auxiliary nut 33c is opened in the upper body of the grooved steel or the square pipe serving as the base rail B5. In addition, a through hole B8 that is slightly larger than the outer diameter of the auxiliary nut 33c but smaller than the outer diameter of the spacer 33d is opened in the lower body of the grooved steel or the square pipe that becomes the base rail B5.
Although not shown as an example of another example, as the base rail B5, it is possible to use a section steel having a H-shaped cross section, a square member, or the like instead of the grooved steel (C-type channel) or the square pipe.

And the structure installation construction method of the example shown by FIG. 6 is demonstrated.
Similarly to the second embodiment shown in FIG. 5, after the base portion 31 and the support portion 32 of the fixture 3 are fixed on the waterproof layer 2, the auxiliary nut 33 c is attached to the screw portion 32 b of the support portion 32 in the third embodiment. Screw together.
Following this, the base rail B5 to be the structure B is installed, and the threaded portion 32b and the auxiliary nut 33c of the support portion 32 are passed through the through hole B8 opened in the lower main body of the base rail B5. Then, the nut 33 b is screwed into the screw portion 32 b of the support portion 32.
Thereafter, the auxiliary nut 33c is tightened from the opening B6 of the base rail B5 toward the upper main body of the base rail B5, and the nut 33b is tightened and sandwiched in the opposite direction.
Finally, a spacer 33d is mounted between the auxiliary nut 33c and the lower main body of the base rail B5 so that the auxiliary nut 33c does not loosen and rotate.

According to the structure installation structure A and the structure installation method according to the third embodiment of the present invention, since the base rail B5 is sandwiched between the nut 33b and the auxiliary nut 33c, the base rail B5 is more stably fixed. Can do. Furthermore, even if the nut 33c is tightened, it is possible to prevent the pedestal 31 from being lifted by the reaction force, and to restrict the lateral movement of the pedestal 31.
Further, since the auxiliary nut 33c is disposed in the opening B6 of the base rail B5, it may be difficult to perform further tightening from above. Therefore, by providing a spacer 33d for preventing loosening so as to come into pressure contact with the auxiliary nut 33c, it becomes possible to prevent the auxiliary nut 33c from loosening, and there is no need for additional tightening, so the base rail B5 can be stably installed over a long period of time. can do.

  In the illustrated examples in Example 2 and Example 3, the concrete base 14 is provided as the base 1, but the present invention is not limited to this, and can also be used as a metal base or an ALC base, and a heat insulating material is provided on these. May be laid.
