BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for installing a support post at a position where the support is to be arranged on an installation surface.

2. Description of the Related Art In recent years, installation of so-called mega-solar power plants, in which a large number of solar cell panels are installed in fallow farmland or the like to generate power, has been carried out.

Generally, as a facility for installing a solar cell panel, a prefabricated frame having two or more legs for supporting the solar cell panel is known. The pedestal has a horizontal bottom surface facing the installation surface, and an upper end on which the solar cell panel is mounted is formed at a predetermined inclination angle that enables efficient photovoltaic power generation.

On the other hand, when the solar cell panel is installed on a sloped land such as a forest, a sloped mount may not be necessary. Normally, when installing equipment on a sloping ground, it is necessary to install the equipment after leveling the sloping ground. Therefore, it is not possible to carry out land leveling work using heavy machinery. Moreover, even when a concrete foundation is placed, if the angle of inclination is too large, the concrete mixer truck cannot enter, and the work is not easy.

In such a sloped land, the applicant of the present application has a method of driving a support post into a position where the support is to be arranged, installing a fixture for holding the support with a stake, and driving a pile into the fixture to fix the support. and provides a fixture therefor (Patent Document 1).

With the method and fixtures disclosed in Patent Document 1, even when a support for placing an installation object such as a solar panel is erected on a slope, it is possible to erect it easily and quickly. work can be done.
