The present invention relates to a structure of a support body of a structure, and more specifically, to an external pipe so that the wind power generator installed higher than the ground of the structure can be firmly supported while absorbing and buffering vibration caused by wind direction, wind speed, and air pressure. The inner space of the inner pipe is inserted to improve durability, and the space between the inner and outer pipes is characterized by a non-contraction mortar or epoxy-filled structure.

Therefore, since the appearance of the body itself is thin, it is related to a body structure that can be harmonized with each other without harming the city view even if installed like a street lamp installed in the city center.

Petroleum, the largest energy source of humanity in the 20th century, is depleted by 2040 and coal by 2100.

This is a warning from the International Energy Agency in 1998. Not only is there a lack of reserves, but oil and coal, represented by fossil fuels, emit carbon dioxide and sulfur dioxide, and are considered as the main culprit of environmental problems such as global warming and extreme weather.

Accordingly, in the United States and Europe, the focus is on developing alternative energy, and among them, it is pollution-free wind energy that is considered to be economical and efficient.

Therefore, in Korea, where there is not enough resources, the maximum use of energy sources existing in Korea is very important. Among them, the use of abundant wind energy in coastal and mountainous areas or breakwaters is a huge amount of energy every year. Considering the fact that imports have been imported, energy self-sufficiency can be contributed to.

Wind power generation is pollution-free natural energy, and the amount of pollutant reduction in the operation of wind power generators is 9g / ㎾h for sulfur and nitrogen oxides, 0.1g / ㎾h for heavy metals, 0.5 ~ 1.0kg / ㎾h for carbon dioxide, and 200g / ㎾h for particulate matter. To this extent, it can greatly contribute to the preservation of clean environment, and is expected to be a means to proactively cope with the atmosphere of suppressing the emission of greenhouse gases caused by the climate change convention recently discussed.

Therefore, the wind power generator is an environmentally friendly device that can be used for tourism resources.

Indeed, large-scale wind farms in the US, Europe, and offshore regions serve as tourist destinations for many tourists every year, making them well suited for large-scale demonstrations and promotions.

Korea also can fully expect side effects of Jeju Island, coastal areas and breakwaters.

On the other hand, a wind power generator is generally composed of a rotor or propeller, a speed increaser (power train), and a generator, and is combined with a rigidly supporting body that provides a height above ground in comparison to the diameter of the turbine or propeller. do.

Therefore, the optimum height of the body varies according to the wind characteristics by altitude / region, so if the wind speed increases according to the shape of the terrain or the direction of the wind, the height of the body changes and the diameter increases.

Therefore, in order to firmly support the wind power generator, the body is externally walled with concrete to a predetermined height from the ground and installed in coastal and mountain areas or breakwaters.

However, the concrete outer wall can firmly support the wind turbine, but because the exterior itself is not beautiful, there is a limit to be installed only in rare places.

In addition, as a method of firmly supporting the wind power generators other than the concrete outer wall, a method of fastening a large pipe or an iron beam to each other was used.

However, in order to guarantee the robustness and stability in the wind power generation system, when only the large pipe or the steel beam is used, the diameter of the pipe connecting the body is increased, requiring much installation space, and using only the expensive large pipe or the steel beam. Because there is a problem that takes a lot of initial installation cost.

Therefore, the wind power generator is generally installed in a place where the wind direction is strong and rarely because the body itself is enlarged and it is difficult to install in the urban area.

In addition, since the pipe constituting the conventional body is thick and simply forms an empty hollow inside, the pipe is not seismically designed to absorb and absorb vibrations transmitted from the outside. there was.

Therefore, the body, a large pipe that supports wind turbines installed in coastal, mountainous areas, and breakwaters, can be damaged during storms or wind speeds. It is difficult to reduce the installation cost, production cost, management cost, expensive production, there is a problem that is difficult to achieve a stable power generation of a constant voltage electricity.

Therefore, an object of the present invention for solving the above problems is to make the body that supports the wind power generator on the ground firmly on the ground, unlike the conventional pipe, while at the same time to reduce the diameter and to produce a beautiful appearance with stable durability It is to use the structure of the supporting body of large structure that can be installed in the coastal and mountain area or the breakwater, which is rare in humans, as well as in the park around the city or in the city.

In order to achieve the above object, the present invention is a body for firmly supporting a building structure located at a predetermined height on the ground and the inner pipe having a predetermined length; A plurality of wings which are arranged along the circumference of the inner pipe in the same length and welded so as to closely support the outer pipe and the inner pipe; An outer pipe which is covered with the same length on the outer circumferential surface of the inner pipe to have a space between the inner pipe and the wing and is in close contact with the wing; A lower flange having a central hole and a plurality of bolt holes formed at an edge thereof to seal the lower part of the inner pipe and the outer pipe into which the wing is inserted; Connection holes in the center to seal the upper pipe and the upper pipe is inserted, and the plurality of injection holes and edges respectively located in the space between the wing and partitioned by arranging between the outer pipe and the inner pipe around the connection hole A lower flange having a hole formed therein; A base arranged between the plurality of bolt holes about the outer circumferential surface of the outer pipe and attached symmetrically upward and downward to reinforce and fasten the outer pipe and the upper and lower flanges; It is characterized by consisting of epoxy or non-shrink mortar filled in the space through a plurality of injection holes to absorb and cushion the shock and shock between the inner pipe and the wing inserted into the outer pipe.
