Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module installation base using tires and a method of manufacturing the same, and more particularly to a solar cell module installation suitable for using a plurality of used tires having a variation in size. TECHNICAL FIELD The present invention relates to a configuration of a tire base for a vehicle and a method of manufacturing the same.

[0002]

2. Description of the Related Art In recent years, due to depletion of fossil fuels and environmental problems caused by using fossil fuels, solar energy has attracted attention as next-generation clean energy.

[0003] The demand for solar cells is increasing year by year, and they are beginning to be used in various places such as roofs of ordinary houses. However, the price of solar power generation systems is still high and is not widely used at present. is there.

[0004] The installation form of the solar cell differs depending on the application and place, but a general method is to provide a mount for installing the solar cell on a structure or the like and form the solar cell on the mount. Metal members are widely used as materials for the gantry, but in order to reduce the cost of the photovoltaic power generation system, it is necessary to form the gantry using members with lower material costs.

[0005] Therefore, if a used tire can be used as a material for the gantry instead of a metal member, the material cost of the gantry can be greatly reduced. At present, it is said that about 4 million used tires are produced annually, and a large amount of used tires can be easily obtained.

[0006]

However, the size of tires (outer diameter, inner diameter (diameter of wheel rim), width, flatness, etc.) differs depending on the type and application of the vehicle, and thus a large amount of used tires is required. If you get, the size will vary. Even if the size of the tire to be obtained is limited to one type, the size of the tire after use usually differs depending on the use condition.

As a method of forming a gantry using used tires, for example, as shown in FIG. 1, used tires 10 are arranged vertically in a hole dug in advance on the ground, a part of which is buried, and an exposed portion is exposed. Member 11 forming a solar cell installation surface on the surface
Is conceivable.

However, when used tires having different sizes are vertically arranged in a line as shown in FIG. 1, the heights of the tires vary, and there is no common circumscribed surface for each tire.
Even if the planar member 11 is provided there, there is a problem that the weight of the solar cell and the planar member 11 is concentrated on some of the used tires, and the inclination angle of the installation surface of the solar cell differs for each mount. I do.

As a solution, it is conceivable to adjust the height of each tire when burying the tire. However, the work of adjusting the position of each tire on site is very inefficient, and the desired operation is not performed. It is extremely difficult to form a solar cell installation surface having a tilt angle.

Further, even if used tires are stacked sideways and a solar cell installation surface is to be formed there, the same problem as in the above-described method occurs.

The present invention has been devised in order to solve the above-mentioned problems. Even when used tires having different sizes are used, the installation surface of the solar cell is supported by all the used tires, It is another object of the present invention to provide a solar cell module installation tire mount having a desired inclination angle of a solar cell installation surface and a method of manufacturing the same.

[0012]

Means for Solving the Problems In order to solve the above-mentioned problems, a tire mount for installing a solar cell module according to the present invention comprises:
The tire comprises a plurality of tires arranged so as to have at least two common circumscribed surfaces, and a concrete member provided on one of the circumscribed surfaces.

According to the solar cell module mounting tire mount of the present invention, the concrete member provided on one common circumscribed surface and the other common circumscribed surface portion are respectively transferred to the solar cell module installation surface or the ground. It can be used as an installation surface. As a result, each tire provided on the gantry is in contact with the concrete member and the ground at the time of construction, so that the weight of the concrete member can be prevented from being concentrated on some tires, and the stability of the gantry is also improved. I do. In addition, the use of heavy concrete members as the installation surface of the solar cell module makes the gantry less susceptible to wind and eliminates the need for foundation work such as burying part of the gantry in the ground. Time is saved.

In the tire frame for installing a solar cell module according to the present invention, if a part of the tire is buried in the concrete member, the tire is mechanically fixed to a contact portion between the tire and the concrete member using a member such as a bolt. It is preferable because there is no need. In addition, it is preferable that at least a part of the tire is cut off and that part is buried in the concrete member because the fixing strength between the tire and the concrete member is improved.

Further, according to the method for manufacturing a tire frame for mounting a solar cell module of the present invention, a plurality of tires are placed in a mold in which a tire holding plate is attached at a desired angle with respect to the bottom. And a first step of arranging the tire holding plate so as to be inscribed therein, a second step of pouring concrete into the form, and a third step of removing the form after the concrete has hardened, And

According to the method of manufacturing a solar cell module mounting tire base of the present invention, a plurality of tires can be formed by using a mold in which a tire holding plate is mounted at a desired angle with respect to a bottom surface. Simply place each tire on the inside and press each tire against the tire holding plate. Even when using tires of different sizes, at least two circumscribed surfaces common to each tire can be easily obtained (one for the tire holding plate and one for the other. Is the bottom of the formwork). In addition, since concrete is poured and hardened in a state having at least two common circumscribed surfaces, there is a problem that the position of the tire is shifted in a later step and the inclination angle of the gantry (the angle formed by the two circumscribed surfaces) is changed. Does not occur. Furthermore, the inclination angle of the gantry can be easily changed only by changing the mounting angle of the tire holding plate with respect to the bottom surface of the mold, and if the same mold is used, the same specifications (size of concrete member and A gantry having a gantry inclination angle) can be manufactured.

In the method of manufacturing a solar cell module-installing tire mount according to the present invention, the tires are arranged in the form while the side of the form opposite to the side on which the tire holding plate is mounted is lifted, and concrete is removed. It is preferable that the tire is poured and solidified, since the stability of the tire is good when the tires are arranged in the mold, and it is not necessary to push the tire from behind so as to hit the tire holding plate.

[0018]
