Description

The present invention relates to an installation structure of a support column, and more particularly, to an improvement of an installation structure of a support column for a solar power generation device.

In recent years, photovoltaic power generation devices have attracted attention as alternative energy sources that do not cause environmental destruction, and for example, many scenes installed on the roofs of buildings have been seen.
As a mode of installing this solar power generation device outdoors such as idle land, solar cell panels are often installed directly on the ground.
However, in this case, there is a disadvantage that the installation area of the solar cell panel narrows the effective use of land. Such inconvenience can be solved, for example, by setting up a support column on the ground and supporting the solar cell panel on top of the support column as shown in Patent Documents 1 and 2.

The solar power generation device described in Patent Document 1 has a structure in which a block is provided at a lower end portion of a support column that supports a solar cell panel, and the block is embedded in the ground.
However, the installation structure in the solar power generation device described in Patent Document 1 is a structure that only embeds the block in the ground, and is not configured to make the embedding strength of the block itself robust.

Moreover, the installation structure and installation method of the solar power generation device described in Patent Document 2 are a column, an embedded structure located at a lower portion of the column, and a fastening for connecting the upper portion of the embedded structure and the lower portion of the column. The embedded structure is one in which at least the outer peripheral side is embedded in the ground via concrete.
Therefore, since the strut and the embedded structure are separate bodies and both are connected via a connecting fixture, the size of each can be made smaller than the integrated type, and handling during transportation and installation is possible. Can reduce the work burden associated with.
However, although the outer peripheral side is buried in the ground via concrete, the connection with the lot number is performed only with concrete and lacks stability. If the buried structure is not lengthened, the ground can be stably grounded. It cannot be installed inside.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the column installation structure of the present invention will be described below in detail with reference to the drawings.

In FIG. 1 to FIG. 3, reference numeral 11 denotes a cylindrical column that is erected on the ground while supporting various devices (not shown) such as a solar cell panel on its upper part.
The cylindrical support column 11 includes a plurality of slits 12 in the lower portion, and is configured to be bent in a direction in which a strip 13 between the slits is opened at a start end portion of the slit 12.

The cylindrical support column 11 is provided with a small circular hole (expanded diameter portion) 14 having a size larger than the width of the slit 12 at the start end portion of the slit 12.
Therefore, even if the concrete poured from the upper part of the cylindrical column 11 loses its place, it flows out from the small hole 14 into a vertical hole 31 (described later) formed on the installation surface and easily enters the vertical hole 31. Concrete can be placed.

The cylindrical column 11 is provided with through holes 15 at appropriate intervals above the column 11. Therefore, the concrete can be easily placed inside the vertical hole 31 through the through hole.
In addition, various apparatuses, such as a solar cell panel, are comprised so that the leg part can be attached to the said support | pillar 11 simply and rapidly. At the time of attachment, it is desirable to connect and fix the flange portion provided at the lower end of the leg portion of various devices to the flange portion 16 provided at the upper end of the column 11 using a bolt nut or the like.

A cylindrical and flat bottom embedded structure 21 is disposed below the cylindrical support 11. In addition, an inclined surface 22 is formed around the upper end opening of the embedded structure 21 so as to swell upward.
That is, the embedded structure 21 is a container structure with a closed bottom, and the interior of the embedded structure 21 is also filled with concrete. After filling the concrete, Thus, the column 11 can be reliably supported.

In the column installation structure in which each part is configured as described above, the installation work at the installation site proceeds as follows.
a) As shown in FIG. 1, a vertical hole 31 having a predetermined diameter is provided in the ground, and the embedded structure 21 is accommodated in the vertical hole 31.

The strip 13 provided at the lower portion of the column 11 is pushed and expanded along the inclined surface 22.

This operation can be performed without requiring a relatively large force due to the presence of the slit 12 and the small hole (expanded diameter portion) 14 provided in the starting end portion of the slit 12.
Further, as shown in FIG. 2, the strip 13 provided at the lower portion of the column 11 is pushed and expanded along the inclined surface 22, and at the same time, the tip thereof is pushed toward the wall surface of the vertical hole 31. .

At that time, the embedded structure 21 has a container structure with a closed bottom, and initially the concrete C is filled into the embedded structure 21. Even if the embedded structure 21 is completely filled with concrete C, and the concrete C loses its place, the concrete 12 flows out of the small hole 14 at the upper end of the slit 12 into the vertical hole 31 and easily enters the vertical hole 31. C is placed.
Similarly, concrete C can be placed inside the vertical hole 31 through the through holes 15 provided at appropriate intervals in the upper part of the support column 11.

d) Finally, in various devices such as solar cell panels, a flange portion provided at the lower end of the leg portion is connected and fixed to a flange portion 16 provided at the upper end of the column 11 using a bolt nut or the like.
Of course, the present invention is configured as disclosed above, but the present invention is not limited to the above embodiments.

Next, FIG. 4 shows another embodiment of the column installation structure of the present invention. In the lower part of the cylindrical column 41, a cylindrical shape with a tip-like cross section 53 having a tip of, for example, 45 ° is shown. The formed embedded structure 51 is arranged. And the inclined surface 52 which swells upwards is formed in the circumference | surroundings of the upper end opening part of the said embedded structure 51, and the cylindrical support | pillar 41 can be attached similarly to the said Example.
The embedded structure 51 is a container structure having a pointed cross section 53 having a bottom of 45 °, and can be driven into a vertical hole 31 provided in the ground, and can be more firmly installed in the ground. .
Of course, concrete C is also filled into the embedded structure 51 from the cylindrical support column 41, and after the concrete C is filled, the support column 41 is surely used as a foundation for a very heavy support column. Can be supported.

Although the present invention is configured as described above, the shape, material, quantity, and other detailed configurations of the above-described embodiment can be made without departing from the scope of the technical idea and object of the present invention. Needless to say, those skilled in the art can make various modifications.

Furthermore, in the above description, installation of solar cell panels is described, but other various devices. Needless to say, it can be used as appropriate in scenes requiring instructions for heavy objects.
