In general, energy consumption in each country is increasing every year, and greenhouse gas emissions from energy use are also increasing rapidly in proportion to energy consumption. Therefore, the development of eco-friendly alternative energy has become a major concern in the energy conservation policy of each country, and the need and importance of alternative energy development is gaining weight as the year progresses.

In recent years, development of energy technology using solar energy, which is pollution-free and relatively easy to secure the energy source, has been actively researched and used among the alternative energy. This solar energy is a technology (photoelectric effect) that converts sunlight directly into electric energy, and consists of a module type solar cell, a battery, and a power inverter. In other words, through this configuration, a clean energy source using sunlight can be used indefinitely.

As a result, solar cell structures are being installed in outdoor areas as well as outdoor areas in general houses and buildings to reduce greenhouse gas emissions.

In order to install such a solar cell structure, a supporting frame for installing a solar cell and a supporting frame for fixing the supporting frame to the ground are essential. That is, the solar cell structure is installed in such a manner that a plurality of support frames are coupled to each other to form a structure, the solar cell module is fixed on the support frame through the support frame, and then the solar cell module is fixed on the support frame.

However, when the supporting frames are coupled to each other to fix the solar cell structure, it is difficult to construct the solar cell due to welding, so that the construction time is long and the labor cost is increased and the overall construction cost is increased. In addition, the welding is permanently fixed and can not be reassembled, and it is not only difficult to repair in the event of breakage, but also has a disadvantage that the welding part is not clean.

On the other hand, Korean Patent No. 10-1037207 discloses an example of a solar cell structure in which a structure is formed using bolts and nuts. However, this patent discloses a solar cell structure in which when a support frame having a C- It is not easy to fasten the nut with a bolt in a narrow space in the interior of the apparatus. Therefore, even when the specialist installs the apparatus, the construction time is long and the workability is deteriorated.

Korean Patent No. 10-1302311 discloses a method of improving the structure of the profile constituting the support frame so that the support frame and the support frame can be easily joined to each other with a bolt and a nut by using a bonding material. There is no structure in which a solar cell can be installed on a support frame. Therefore, in order to install a solar cell on a support frame, a separate C-shaped pipe or another member must be used. Therefore, the installation cost and construction cost increase, have. In addition, since there is no structure for holding the bolt head when the bolt head is inserted into the open part and the bolt head is fixed by the nut, it is necessary to tighten the nut while pulling the screw part of the bolt. There is a problem.

Here, the connection fixing member 300 may be referred to above.

Now, an installation method for installing a solar cell structure by applying a solar cell structure support according to the present invention will be described.

When the solar cells 10 configured in a module form are inclined, a plurality of support frames 100 are first prepared, and then arranged so as to cross each other in the horizontal direction and the vertical direction at predetermined intervals. In this state, after the connecting member 200 and the connecting fixing member 300 are prepared, the connecting member 200 is placed on the orthogonal face of the supporting frame 100 disposed at an intersection with each other, The vertical surface 202 is fixed through a connection fixing member 300 which is inserted into the coupling groove 120 of the support frame 100 located at the upper portion through the assembly hole 210, Are fixed to each other through a connection fixing member 300 which is inserted into the coupling groove 120 of the lower support frame 100 through the assembly hole 210, Thereby forming a support frame structure.
