Description

  The present invention relates to a support leg for a structure that can be firmly fixed to the ground.

  When installing a structure on the ground, it is necessary to fix the structure to the ground. In particular, a structure in which support legs such as pillars and poles are fixed to the ground is liable to fall down due to wind and vibration, and therefore needs to be fixed more firmly to the ground. As a method of making the foundation of the support leg, for example, as shown in Patent Document 1, there is known a method of laying concrete around a foundation pipe of a structure, or fixing the foundation pipe by compressing earth or sand or gravel. It has been. Further, as shown in Patent Document 2, a mandrel is inserted through cement milk into a pile hole drilled in the ground, and a grout is injected into the mandrel along the support leg of the gantry to thereby fix the leg fixing part. It is known to form.

By the way, in recent years, a solar power generation facility (farming power generation facility) of a type in which a column is continued and farming is newly developed and is in a practical stage. When a farm-type power generation facility is installed, it is possible to achieve both agriculture and solar power generation on one farm ground.
On April 1, 2013, the Ministry of Agriculture, Forestry and Fisheries issued a notice entitled “Regarding the handling of the farmland diversion permit system for solar power generation facilities etc. that continue to operate with props” (March 31, 2013). Date). By this notice, if you set up a prop on the farmland and install power generation equipment such as solar power generation equipment in the upper space while continuing farming, you need a temporary diversion permission under the Farmland Law for the prop Was revealed.
As a requirement for this temporary diversion permission, it is required that the column is “a column that can be easily removed with a simple structure”.

Since the above-described method includes a step of fixing the support legs to the ground using concrete, the operation becomes complicated. In particular, the method described in Patent Document 2 is useful when constructing a large-scale facility on soft ground, but it is expensive and complicated.
And depending on the nature and purpose of the structure, and the installation location, it may not be desirable to perform foundation work that is costly and complicated. For example, there are cases where small-scale solar power generation is performed using idle land such as abandoned farmland with a small area, or farm-type power generation facilities are installed. If the above-mentioned method is used to install a support frame for a small-scale solar cell module, the cost is high, and it does not necessarily lead to the expansion of the use of renewable energy using the power generation electricity acquisition system.

  This invention is made in view of such a problem, and makes it a subject to provide the support leg which can be fixed to a ground strongly, does not cost at the time of installation, and can be built easily. Another problem to be solved by the present invention is to provide a support leg that makes it possible to construct a structure at a set height regardless of the hardness of the ground.

  In addition, the problem to be solved by the present invention is a “support that can be easily removed with a simple structure” that can be used as a support for the above-described farm-type power generation facility, and is not affected by the hardness of the ground. It is also possible to provide a support leg that makes it possible to build at a set height.

This invention which solves the above-mentioned subject is provided with a cylindrical leg which has an opening for inserting a foundation pile in a lower end, and a fixed body provided at the lower end of the leg, and the fixed body inserts an anchor. It is a support leg characterized by having the insertion port for doing.
According to the support leg of the present invention, the depth of the foundation pile can be freely set according to the hardness of the ground, and the height of the structure depends on the depth of the foundation pile. No.
Moreover, since the support leg of this invention has a fixing body, it can be firmly fixed to the ground.

Moreover, with the preferable form of this invention, the said fixed body is provided so that it may go around the said leg.
According to this form of the present invention, it is possible to more firmly fix the support leg by the fixed body to the ground.

In a more preferred form of the present invention, the fixed body is composed of a plurality of plate-like members, the plate-like members are provided at a predetermined interval, and are set with respect to a horizontal plane whose vertical line is the central axis of the leg. It has a lead angle.
According to this aspect of the present invention, the support legs are less likely to come off the ground due to the upward force in the vertical direction, and therefore the support legs can be more firmly fixed to the ground.

In a preferred embodiment of the present invention, a fixing means for fixing the foundation pile inserted through the leg and the support leg is provided.
According to this form of the present invention, it is possible to prevent the support legs from coming off the foundation pile.

The present invention also relates to a structure having two or more support legs, wherein the two or more support legs are connected to each other by a beam member.
2. Description of the Related Art Conventionally, a structure that includes a plurality of support legs and is installed by driving each support leg into the ground is known. However, in this conventional structure, the height of the structure changes according to the depth at which the support leg is driven. That is, since it is necessary to drive the support leg deeply in the soft ground, the height of the structure becomes low and it is difficult to achieve the intended height. Moreover, when the hardness of the ground differs depending on the place where each support leg is driven, the depth at which each support leg is driven becomes uneven, and as a result, the structure is inclined obliquely.
According to the structure of the present invention, the depth of the foundation pile can be freely set according to the hardness of the ground, but the height of the structure does not depend on the depth of driving of the foundation pile. Therefore, the height of the structure can be set to a predetermined height regardless of the ground on which the structure of the present invention is installed.
Moreover, since the foundation pile can be driven in first and the leg body can be put on the foundation pile, it is easy to construct and finish with high accuracy.

  According to the present invention, it is possible to provide a support leg that can be strongly fixed to the ground, is not costly for installation, and can be easily constructed. Further, it is possible to provide a support leg and a structure whose height does not change depending on the hardness of the ground (depth at which the foundation pile is driven).

In addition, according to the present invention, it is a “support that can be easily removed with a simple structure” that can be used as a support for a farm-type power generation facility, and the height of the leg can be freely controlled regardless of the hardness of the ground. It is possible to provide a support leg that can be set and a platform for a solar module in an agricultural power generation facility.
Since the support leg of the present invention is low in installation cost, it is possible to easily recover the cost of installation using an electricity purchase system generated by a farm-type power generation facility. That is, the present invention can contribute to the expansion of the use of renewable energy.

Hereinafter, each structure of the support leg of this invention is demonstrated in detail.

(1) Leg body The leg body in the support leg of this invention takes the cylindrical structure which has an opening part for inserting a foundation pile in a lower end. Here, the foundation pile means a pile serving as a foundation for fixing the structure to the ground, and the shape thereof may be a prismatic type or a cylindrical type.
If the shape of a leg can penetrate a foundation pile, the shape will not be specifically limited, A prismatic type or a column type may be sufficient.
The leg material is not particularly limited, but is preferably made of metal.

In preferable embodiment of this invention, the fixing means for fixing the foundation pile penetrated to the leg body and the said support leg is provided.
The fixing means is not particularly limited as long as it can fix the foundation pile and the leg. Particularly preferably, the fixing means includes a screw hole penetrating the inside and outside of the leg and a bolt corresponding to the screw hole. In such an embodiment, after the foundation pile is inserted into the leg, the bolt presses against the foundation pile in the leg, and the leg and the foundation pile are fixed.

(2) Fixed body The fixed body in this invention has the insertion port for inserting an anchor, and is provided in the lower end of a leg.
The leg material is not particularly limited, but is preferably made of metal. Preferably, the leg body and the fixed body are made of metal and fixed by welding each.

The fixed body has an insertion port for inserting the anchor, and the form is not particularly limited as long as the support leg can be fixed to the ground by inserting the anchor into the insertion port and driving the anchor into the ground. .
Preferably, the fixed body only needs to have a structure extending from the lower end of the leg body in a substantially plane direction with the center line of the leg body as a vertical line, and more preferably, a plurality of insertion openings are provided. A structure that can be fixed to the ground with an anchor.

In a preferred embodiment of the present invention, the fixed body is provided so as to go around the leg. More preferably, the fixed body is provided so as to extend radially from the center line of the leg.
Specifically, it is preferable that the fixed body has a flange shape protruding outward from the leg body, and a plurality of insertion holes are provided at predetermined intervals.

More preferably, a plurality of plate-like members are provided on the leg at predetermined intervals, and an insertion port is provided in each plate-like member. In this embodiment, more preferably, the plate-like member is provided so as to have a lead angle set with respect to a horizontal plane in which the central axis of the leg is a vertical line.
In such an embodiment, the support leg is unlikely to come off the ground due to the upward force in the vertical direction.
In this case, the lead angle may be any as long as it can fix the support leg to the ground by driving an anchor and can counter the upward force in the vertical direction.

<2> Structure The present invention also relates to a structure including two or more support legs, and the two or more support legs are connected to each other by a beam member.
Here, the structure in the present invention is supported by two or more support legs (pillars, poles, etc.), specifically, a vegetable support, a wisteria shelf, a bird net, an agricultural net, an agricultural house, etc. Preferred examples include agricultural structures, gardening structures such as gardening, light construction architectural structures such as house fences, nets such as volleyball, tennis, and badminton, and platforms that support solar cell modules.

In particular, when the present invention is implemented as a stand for a solar cell module, the merit is great.
In recent years, attempts have been made to perform small-scale solar power generation using idle land such as abandoned farmland with a small area. In this case, it is necessary to fix the mount for installing the solar cell module to the ground. Conventionally, when installing a pedestal, there is a method in which a foundation is fixed with concrete or the like and a support leg is installed, but this method is complicated and expensive. For this reason, when power is generated in a small area, the expenditure due to installation costs may exceed the income from power generation, which is not an appropriate method.
On the other hand, there is a method of driving the support leg of the gantry as a foundation pile to the ground as it is, but although it does not cost, it is difficult to set the gantry to the set height because the depth of driving depends on the hardness of the ground There is a problem that it is.
According to the present invention, no matter how deep the foundation pile is driven, since the support legs are used covering the foundation pile protruding from the ground, the height of the gantry can always be set to the set value.
And since installation cost is cheap, installation expense can be easily collect | recovered with the income by electric power generation. That is, the structure of the present invention contributes to the expansion of the use of recycled energy.

Further, when the structure of the present invention is implemented as a solar module mount in a farm-type power generation facility, the merit is particularly great.
The support legs constituting the present invention correspond to the “posts that can be easily removed with a simple structure”, which is a requirement of the post in the farm-type power generation facility.
Moreover, since the structure of the present invention can freely set its height, the farming-type power generation has a height that allows the farmer to farm without inconvenience under the upper solar panel. Facilities can be provided.

Furthermore, there is a great merit when the structure of the present invention is implemented as an agricultural structure.
Agricultural structures such as bird damage nets and agricultural houses using the structure of the present invention can be easily set to a height at which a farmer can work without inconvenience.

In the present invention, the beam member refers to a member that bridges a plurality of support legs.
The material of the beam member is not particularly limited, but when the leg body is made of metal, it is preferable that the beam member is also made of metal and fixed to each other by welding.

The number of beam members is not limited to one for the two support legs, and two or more beam members may be provided.
Further, the beam member does not need to be orthogonal to the support leg.
For example, two support legs may be coupled by two beam members intersecting in an X shape.

  In the structure of the present invention, the setting heights of the plurality of support legs need not be the same, and can be set as appropriate according to the shape of the structure.

Example 1
A support leg of the present invention of Example 1 will be described with reference to FIGS.
The support leg of Example 1 includes a prismatic leg 10 and four plate-like members 20 extending radially from four side surfaces of the leg 10 (FIG. 1).
The leg 10 has a cylindrical structure having an opening 12 at the lower end, and the foundation pile 3 can be inserted through the opening 12 (FIGS. 1 and 2).
Further, the leg 10 includes a screw hole 112 on the side surface and a bolt 111 corresponding to the screw hole 112. After inserting the foundation pile 3 into the leg body 10, the leg body 10 and the foundation pile 3 can be fixed by tightening the bolt 111 (FIG. 2).

The plate-like member 20 is provided with an insertion port 22 for inserting the anchor 4.
The plate-like member 20 is provided on the leg body 10 so as to have a lead angle with respect to a horizontal plane having the central axis of the leg body 10 as a vertical line.
Further, the plate-like member 20 is provided at a right angle to the side surface of the leg 10.
The leg 10 and the plate member 20 are both made of metal, and the plate member 20 is fixed to the leg 10 by welding.

Next, the usage method of the support leg of Example 1 is demonstrated.
First, the foundation pile 3 is driven into the ground. The depth at which the foundation pile 3 is driven is changed as appropriate according to the hardness of the ground. In other words, it should be driven deeply on soft ground.
Next, the foundation pile 3 is inserted from the opening 12 of the leg 10, and the foundation pile 3 is inserted through the leg 10.
Then, the anchor 4 is inserted from the insertion port 22 of the plate-like member 20, the anchor 4 is driven into the ground, and the plate-like member 20 is fixed to the ground.
And the foundation pile 3 and the leg 10 are fixed by squeezing the bolt 111.
In addition, although the column-shaped foundation pile 3 is represented in FIG. 1, the shape of a foundation pile may be a prism.

Thus, the support leg of Example 1 installed in the ground is fixed to the ground by the foundation pile 3 and the four anchors 4, and is fixed to the ground very firmly.
Further, since the plate-like member 20 has a lead angle, the four anchors 4 are driven into the ground obliquely in different directions. Therefore, the support leg of Example 1 has a structure that is not easily removed from the ground by a force in one direction.

(Example 2)
The configuration of the support leg of the second embodiment of the present invention is almost the same as the configuration of the support leg of the first embodiment.
However, in the support leg of Example 1, the plate-like member 20 is provided at a right angle to the side surface of the leg 10, whereas in the support leg of Example 2, the plate-like member 20 is inclined downward. It is attached to the side surface of the leg body 10 at an angle (see FIG. 4).
In the support leg of the second embodiment, the anchor 4 driven through the insertion opening 22 is driven into the ground along a straight line having a twisted relationship with the center line of the leg 10 (see FIG. 4).
Therefore, the support leg of Example 2 is strongly fixed to the ground, and has a structure that is not easily removed from the ground by wind or vibration.

(Example 3)
The support leg of Example 3 is demonstrated with reference to FIG.
The support leg of Example 3 has the column-shaped leg 10 and the flange part 21 as a fixed body.
The side surface of the leg 10 is provided with two screw holes 112 and two bolts 111 as fixing means.
The flange portion 21 is provided with insertion openings 22 at regular intervals so as to go around the leg 10.
Except for the configuration described above, the support legs of the third embodiment are the same as the support legs of the first embodiment.

(Example 4)
The fourth embodiment is a gantry in which the two support legs 10 of the second embodiment are provided and each support leg 10 is connected to each other by a beam member 6.
The beam members 6 are made of the same metal as the legs 10 and are connected to each other by welding.

Next, the installation method of the mount frame of Example 4 is demonstrated.
First, the two foundation piles 3 are driven into the ground at the same interval as the interval between the two legs 10 in the gantry of the fourth embodiment. At this time, the two foundation piles do not need to be driven to the same depth. What is necessary is just to change suitably the depth to drive in according to the hardness of the ground of the point which drives each foundation pile 3. FIG.
Next, the foundation pile 3 is inserted from the opening 12 of the leg body 10, and the foundation pile 3 is inserted through each of the two leg bodies 10.
Then, the anchor 4 is inserted from the insertion port 22 of the plate-like member 20, the anchor 4 is driven into the ground, and the plate-like member 20 is fixed to the ground.
And the foundation pile 3 and the leg 10 are fixed by squeezing the bolt 111.

The gantry of Example 3 fixed to the ground by the support legs of Example 1 is very strongly fixed to the ground. Therefore, even if a solar cell module that is easily affected by wind is installed on the gantry of Example 3, the fixing between the support leg and the ground is difficult to loosen.
That is, the present invention can provide a very stable frame.

  Further, as described above, the gantry of the fourth embodiment does not depend on the hardness of the ground, and can always be installed with the set value height.

  The present invention can be applied to installation of a support leg and a structure using the support leg. In particular, it can be widely applied as a frame for solar modules to be installed on farmland and structures for agriculture.
