Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base structure for a mount of a solar cell array that supports a mount holding a solar cell array.

[0002]

2. Description of the Related Art Conventionally, a structure shown in FIG. 6 is known as a base structure for a mount of a solar cell array installed on the ground. In FIG. 6, 1 is a solar cell array, 2 is a pedestal that holds the solar cell array, 3 is a support column that holds the pedestal 2, 4
Is the foundation body that supports the columns.

By the way, the load applied to the foundation body 4 includes a self-weight load, an earthquake load, and a wind load. Although the directions in which these loads are applied are different, the wind load that lifts the solar cell array 1 is the largest. Become. Therefore, the weight of the base body 4 itself is increased, and further, as shown in FIG. 6, the size of the base body 4 is increased and the base body 4 is embedded in the ground, and the portion within the broken line for supporting the extraction load is increased. There is. This prevents the foundation body 4 from being pulled out by a wind load.

[0004]

As described above, since the conventional base body 4 is made large to support the pulling load due to the wind load, it can be installed in the ground unless the ground is greatly excavated. Therefore, there is a problem that the construction cost is high and the installation work becomes large-scale.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a solar cell array in which the construction cost is easy and the solar cell array can be installed by a simple construction. It is to provide a foundation structure for a gantry.

[0006]

In order to achieve the above object, the present invention is a base structure for a mount of a solar cell array that supports a mount holding a solar cell array, and is provided with a barbed portion having a barb at the tip. The pile is driven into the ground to a predetermined depth, a support portion having a diameter larger than the diameter of the pile is provided at the rear portion of the pile, the support portion is embedded, and a column for holding the mount is provided on the support portion. The pile supports the pulling load due to the wind, and the supporting portion supports the load of the solar cell array or the like.

[0007]

According to the present invention, it is not necessary to excavate the ground because a pile provided with a barbed portion having a barb at its tip is driven into the ground to a predetermined depth and the pulling load by wind is supported by the pile. Further, since a support portion having a diameter larger than the diameter of the pile is provided at the rear portion of the pile and the support portion supports the load of the solar cell array or the like, the support portion may be small.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a base structure for a mount of a solar cell array according to the present invention will be described below with reference to the drawings.

In FIG. 1, 11 is a solar cell array, and 12 is a pedestal holding the solar cell array. 13 is a pedestal 12
The column 13 is a metal column that holds the column, and the column 13 has a pile portion 14 that is driven into the ground to a predetermined depth. Pile 14
As shown in FIG. 2, a barbed portion 16 having four barbs 15 is provided at the tip of the.

The barb 15 widens from the tip toward the rear, and the barb 15 serves to support the withdrawal load.

A support portion 20 is provided on the pillar 13 in a state of being buried in the ground, and the support portion 20 supports the load of the solar cell array 11 or the like.

As shown in FIG. 3, the support portion 20 is composed of a columnar block having a diameter larger than that of the support column 13 and made of concrete or the like. A pillar 13 is provided at the center of the support 20.
A through hole 21 having a diameter larger than the diameter of is provided, the pillar 13 is passed through this through hole 21, and the gap formed between the through hole 21 and the pillar 13 is filled with concrete 23, and the supporting portion 20 is provided. Prop
13 is fixed.

Next, the assembling order of the gantry structure of the above embodiment will be described.

First, as shown in FIG. 4, the support columns 13 and 13 are driven to a predetermined depth, and the holes 30 for the supporting portion 20 are formed.
Are set on the ground (actually four columns 13 are driven in). Next, as shown in FIG. 5, the through holes 2 of the supporting portions 20 and 20 are formed.
1 to be inserted from the upper ends of the columns 13, 13 to bring the supporting portions 20, 20 to the position of the hole 30, and to fill the gap formed between the through hole 21 and the column 13 with concrete 23, Supports 20,20
To the columns 13,13. Then, the supporting portions 20, 20 are buried as shown in FIG. 5, and the upper portion 20a thereof is brought out from the ground. After that, the pedestal 12 is attached to the upper ends of the columns 13 and 13, and the solar cell array 11 is installed on the pedestal 12.

As described above, since the support column 13 is driven into the ground to a predetermined depth and then the support portion 20 is fixed to the support column 13, the work is simple and the work cost is low. Becomes In addition, the pull-out load due to the wind load is supported by the barb 15 of the barbed portion, so
Since 20 only needs to support its own weight, and therefore, it is not necessary to increase the weight of the supporting portion 20 and it is not necessary to increase the weight, so that the excavation in the ground for burying the supporting portion 20 is small. It will be good.

In the above-described embodiment, the pile portion 14 is provided on the single column 13 that holds the gantry 12. However, the pile portion and the column that holds the gantry 12 are composed of different members, and the support portion is formed. They may be connected at 20.

[0017]

According to the present invention, the pile is driven into the ground to a predetermined depth, and then the support portion 20 is fixed to the rear portion of the pile, so that the work is simple and the work cost is low. Will be cheaper. In addition, since the pull-out load due to the wind load is supported by the barb of the barbed portion, the support portion only needs to support its own weight.Therefore, it is not necessary to increase the weight of the support portion, and it is not necessary to increase the weight. Excavation in the ground to bury the part may be small.
