Description

  The present invention relates to a method for installing a gantry.

  In recent years, so-called mega solar installations have been performed in which a large number of solar battery panels are installed on fallow farmland or the like to generate power. In general, as a facility for installing the solar cell panel, an assembly-type gantry including two or more legs for supporting the solar cell panel is known (see, for example, Patent Document 1).

  As a method of fixing the gantry to the installation surface using a fixture, conventionally, after fixing the fixture to the installation surface, fixing each leg of the gantry to each fixture and assembling the gantry Has been done. At this time, if the fixing positions of the fixtures with respect to the installation surface are inappropriate, the assembly accuracy of the frame cannot be ensured when the frame is assembled, and the frame is not supported by the supported object. Can not be supported well.

  Therefore, in order to secure the assembly accuracy of the gantry, when fixing the fixture to the installation surface, surveying is performed in advance to accurately align not only the horizontal position but also the height direction position with respect to the installation surface. doing.

  However, in the conventional method, since it is necessary to accurately position and fix the fixture to the installation surface, complicated construction is required, and work time and work cost are increased. In particular, in a mega solar that requires a large amount of solar cell panels, a large amount of frames are installed, which further increases work time and work cost.

  An object of this invention is to provide the installation method of the mount which eliminates this inconvenience and can be constructed quickly and easily.

In order to achieve the above object, the present invention provides a method of fixing an assembling-type gantry comprising two or more legs to an installation surface using a fixture fixed to the legs, the fixture comprising: A leg holder attached to the leg and holding the leg movably in the axial direction; and a pile holder connected to the leg holder and holding a driving pile driven into the ground, Attaching each leg holding part to each leg, grounding each leg to the installation surface or embedding in the installation surface so that each leg matches the assembly position of the gantry , A step of performing assembly of the gantry in parallel, a step of fixing the fixture to the installation surface by driving the driven pile into the ground and holding the pile in the ground, and the leg portion and the leg holding portion And a step of fixing the two.

  In the present invention, first, the leg holding portion of the fixture is attached to each leg portion of the gantry before assembly. At this time, the leg holding part holds the leg part so as to be movable in the axial direction.

  Next, each leg of the gantry before assembly is grounded on the installation surface or embedded in the installation surface so that each leg matches the assembly position of the gantry, and the gantry is assembled.

  Normally, assembly-type mounts are manufactured under quality control at factories, etc., so that if the legs are not fixed to the installation surface, each leg must match the assembly position of the mount. Thus, the gantry can be assembled with high accuracy. In the present invention, since the grounding or embedding of the legs on the installation surface and the assembly of the mount are performed in parallel, the assembled mount can ensure the assembly accuracy.

  At this time, when the installation surface is horizontal, each leg can be matched to the assembly position of the gantry by grounding each leg to the installation surface.

  On the other hand, when the installation surface has irregularities and the height of the installation surface on which one leg is grounded and the installation surface on which the other leg is grounded are different from each other, If it is made to contact with, both leg parts will shift from the assembly position of the above-mentioned frame.

  Therefore, when the installation surface has unevenness, either one or both of the one leg portion and the other leg portion are embedded in the installation surface, so that each leg portion is assembled to the mounting position of the gantry. Can be matched. At this time, since the leg holding part holds the leg part so as to be movable in the axial direction, when the leg part is embedded in the installation surface, the entire fixture is moved upward with respect to the leg part. Thus, the pile holding part can be prevented from being embedded in the installation surface.

  Next, the fixing tool is fixed to the installation surface by driving the driven pile into the ground and holding it in the pile holding portion. At this time, by moving the entire fixture upward with respect to the leg portion, the pile holding portion is located above the installation surface, so that the driven pile can be driven easily.

  Next, each leg part of the said base and the leg holding | maintenance part of each said fixing tool are fixed. As described above, the gantry can be fixed to the installation surface using the fixing tool.

  According to the present invention, it is not necessary to perform an accurate survey in advance when the legs of the gantry are grounded on the installation surface or embedded in the installation surface, so that the construction can be performed quickly and easily. In addition, since the gantry can be assembled with high accuracy, the gantry can hold the object to be supported well.

Moreover, in this invention, it is preferable that the leg holding | maintenance part of the said fixing tool hold | maintains the said leg part so that a movement is possible to an axial direction, and is movable so that a horizontal direction is possible.
In the present invention, it is preferable to inspect that the gantry can support the supported object after the step of assembling the gantry and before the step of fixing the leg portion and the leg holding portion. . By inspecting that the gantry is assembled so as to be able to support the supported object, the gantry in which the leg part and the leg holding part are fixed and installed on the installation surface more reliably supports the supported object. Can be supported well.
