By the way, in the recent mega solar system, the improvement of the solar panel mount has progressed, the structure has been simplified and the weight has been reduced, and the mounting of the mount to the foundation pile has also been driven into the ground. A strut construction structure is adopted in which a pillar is formed on the ground using a pile, and the support point part of the gantry is integrated with this strut. Also, in order to reduce the foundation pile and strut, the gantry is composed of two pillars. The mounting of the gantry is simplified, such as the form of supporting with a single column from the supporting form.
A construction example of such a gantry has been proposed in Patent Document 2 (Note that since this Document 2 was filed on May 28, 2012, it has not been published yet at the time of filing this application). The construction method of the mount of this literature 2 is shown in FIG. As shown in FIG. 3, the gantry 3 includes a crosspiece 31 including a vertical crosspiece and a horizontal crosspiece, first and second arms 32 and 33 each having one end connected to the vertical crosspiece, and the first and second arms. The other end of the arms 32 and 33 is connected, and a support member 34 that serves as a support point for the gantry 3 is provided. There is no conventional support column or support column base, and the structure is simplified. In attaching the gantry 3, first, as shown in FIG. 3 (1), the hole 10 is excavated in the ground, the core material 11 is inserted into the hole 10, and the upper portion of the core material 11 is protruded above the ground, so that the hole 10 The foundation pile 1 is embedded and formed in the ground by filling and solidifying the filling solidified material 12 having expandability. Next, as shown in FIG. 3 (2), a fixing member 35 for the gantry 3 is attached to the upper part of the core material 11 of the foundation pile 1, and a cylindrical frame body around the upper part of the core material 11 of the foundation pile 1 on the ground. 20 is installed, the support member 34 of the gantry 3 is arranged in the cylindrical frame 20 from the upper part of the cylindrical frame 20, and is fixed to the fixing member 35 on the upper part of the core material 11 via a bolt (not shown). Then, as shown in FIG. 3 (3), concrete 22 is placed in the cylindrical frame 20, and a support column 2 is formed in connection with the upper portion of the foundation pile 1. 34 is fixed.
In this way, the gantry 3 is improved, and the gantry 3 is integrated with the support column 2 provided on the foundation pile 1, so that the gantry 3 and the foundation are compared with the conventional foundation pile structure described above (Patent Document 1). The mounting of the gantry 3 is simplified in that an anchor is not required for coupling with the pile 1.

However, in the case of mounting the gantry 3, the support point of the gantry 3, that is, the support member 34 of the gantry 3 is arranged from the upper part of the cylindrical frame body 20 into the cylindrical frame body 20, and the fixing member 35 above the core material 11. In order to fix the lightweight base 3 in a predetermined direction and angle in order to place the concrete 22 in the cylindrical frame 20 with a bolt, and to fix it to the column 2 with high precision, As shown in FIGS. 3 (2) and 3 (3), it is necessary to support the gantry 3 with many temporary materials 41 such as a temporary scaffolding so that the gantry 3 does not wobble. Unnecessary temporary material 41 is indispensable at the time of construction of the mega solar system. In particular, in the type that supports the gantry 3 with one pillar, the gantry 3 is not supported. Can not be installed
Therefore, a lot of temporary materials 41 are indispensable for the attachment of the gantry 3, and the cost required for the temporary materials 41 themselves, the loading and assembly of the temporary materials 41, and the removal of the temporary materials 41 after the gantry 3 is installed. The cost required for carrying out must be increased.
As described above, by improving the solar panel mount 4 and simplifying the structure of the solar panel mount 4 and reducing the weight, the cost required as a solar power generation facility is reduced. The result is a trade-off that the construction cost required to install the equipment increases.

  The present invention focuses on and solves the technical problem of such a trade-off.
