We live in a cutting-edge society that is changing day by day.

As a result, the quality of life is improving day by day, but problems such as environmental pollution, climate change and energy depletion are occurring due to the indiscriminate use of resources.

Due to various problems, new and renewable energy is being researched and developed worldwide. Renewable energy is a combination of new and renewable energy, which is the main cause of existing environmental pollution. It can refer to energy that is converted into renewable and eco-friendly energy, including hydropower, wind power, and biological organisms, and used. Representatively, there are solar power, solar heat, bio, hydroelectric power, and wind power, and new energy includes fuel cells and hydrogen energy. there is

Among these renewable energies, the energy we use most easily is solar energy, which refers to the energy using a photovoltaic cell that converts the light energy of the sun into electrical energy using the photoelectric effect. A solar panel equipped with a photovoltaic cell that converts electricity is essential.

Solar energy is developing rapidly, and the use of solar energy is legally enforced along with the current nuclear power plant policy of the Korean government, and accordingly, the use of solar energy is rapidly increasing.

As usage increases, installation methods of solar panels, which are essential, are also being developed and developed, and are installed in various places and locations.

Representatively, it can be installed on the roof of a house, and the roof of a house is composed of various shapes and materials such as a sloped roof, an outside sloped roof, and a flat roof.

Conventionally, when installing solar panels, various roof shapes and perforated brackets cannot be moved, so it takes a lot of people and a long time to install multiple structures in parallel, and the problem of exposure to worker safety accidents After installation, there is a risk of corrosion and damage due to external environments such as wind and rain, and there is a problem that human damage occurs when damaged.

The present invention according to the above configuration can expect the following effects.

The bracket of the present invention can move horizontally when installing a solar panel structure and adjust the distance between the solar panel structures, making it easier to install than the method of fixing the bracket through a perforation on the upper part of the roof of the prior art. do.

In addition, in the case of the prior art, the fixing bolts fixed to the roof support the external force transmitted through the solar panel structure in a cantilevered state, so that the bending deformation of the fixing bolts increases and the bracket is fixed by repetition of these bending deformations. In order to do this, deformation may occur in the perforated hole, and rainwater and foreign substances may flow in, and damage to the entire solar panel may be concerned due to damage of the bolt.

Due to this problem, the present invention makes it possible to arrange the fixing part attached to the two protrusions of the steel frame and the fastening part to which the solar panel structure is installed spaced apart from each other.

Due to the mutual separation between the fixing part and the fastening part, the load of the solar panel structure installed on the fastening part is transmitted vertically to the fastening part, and the load transmitted to the fastening part can be distributed to the fixed part attached to the two protruding parts, and distributed. It is possible to prevent the risk of deformation and damage in advance by reducing the external force applied to the fixing bolt due to the applied load.

As the deformation of the fixing bolt is lowered, the deformation of the fixing hole of the attachment part is suppressed, rainwater and foreign substances do not flow into the fixing hole where the deformation does not occur, and there is no concern about damage to the entire solar panel due to damage of the bolt. The period of use of the solar panel may be increased, which may ultimately lead to product quality improvement.

In addition, the inner surface of the fastening portion is provided with an inner projection to which the bolt is fixed, so that the bolt may not rotate when the solar panel structure is installed, and the nut can be easily fastened due to the non-rotating bolt.

Additionally, as the material of the present invention, it may be possible to use Posmac steel, hot-dip galvanized steel, and stainless steel as main materials.

First of all, PosMAC is a corrosion-resistant steel developed and produced by POSCO that does not rust easily. Corrosion resistance can be 5 to 10 times higher than that of hot-dip galvanized steel (GI) with coating adhesion, and corrosion of cut surfaces can be prevented by magnesium promoting the formation of a dense corrosion product (Simonklite) film, and conventional hot-dip galvanized steel The same level of workability, paintability and weldability of the steel sheet (GI) may be possible.

PosMAC has better corrosion resistance than stainless steel, which is stronger than carbon steel, so it can be used in high temperature and high humidity environments and areas with a lot of fine dust.

Next, the hot-rolled steel sheet is pickled and rolled as a hot-dip galvanized steel sheet, and the unannealed steel sheet is passed through a zinc bath in a molten state, and the plated steel sheet enables thicker plating than the electro-galvanized steel sheet, resulting in more zinc (Zn) self-sacrifice. As a method, it may have excellent corrosion resistance, excellent paintability and workability, and may be produced by selecting various coating amounts.

Hot-dip galvanized steel sheet has the advantage of being cheaper than other materials, but there is a risk of peeling of the film due to physical impact, etc., and the peeled part is vulnerable to corrosion, so it may be possible to be careful during transportation and construction.

Lastly, stainless steel is an alloy steel in which about 10% or more of chromium (Cr) is added and nickel, etc. is added to secure corrosion resistance. The added chromium (Cr) forms a passive film of Cr2O3 on the steel surface to block oxygen. and, as a result, it may be possible to prevent corrosion.

Stainless steel has excellent heat resistance, low thermal conductivity, excellent corrosion resistance due to the mixture of nickel and chromium, and excellent strength, but once hardened, stainless steel has the disadvantage of being difficult to further process It may be possible to be careful during processing.

Based on the above configuration, a method of using the present invention will be described.
