Here, the box is formed with an outlet for discharging internal air to the outside and an inlet for introducing external air to the inside, and a plant seedling can be mounted therein. In addition, the light source means is provided with a light source installed in the upper part of the plant seedling in order to supply light to the plants of the plant seedling, and the height of the light source can be adjusted as the plant grows. In addition, the carbon dioxide supply means supplies carbon dioxide. In addition, the air conditioning means sucks the air inside the box discharged from the discharge port and the carbon dioxide and external air supplied from the carbon dioxide supply means to make mixed air, and after making the temperature and humidity of the mixed air and the concentration of carbon dioxide constant, It has a configuration to supply mixed air into the box through the inlet.

However, the conventional prefabricated greenhouse simply has a structure that provides light to plant seedlings by irradiating a light source inside a box having a cylindrical or closed structure, that is, it can provide an environment for plants to grow by sunlight. Because there is no sterilization of bacteria or bacteria in the soil, there is a problem that plants have weak properties to diseases and pests.

In addition, in the conventional prefabricated greenhouse, since the internal space of the box does not have a temperature at which plants can grow by sunlight, an appropriate temperature must be maintained by separately configured heating and cooling means even during the daytime when sunlight is irradiated, so the temperature There is a problem that a lot of cost is required for maintenance.

1 to 3 are a perspective view, a front view and a side view showing the appearance of a prefabricated greenhouse according to a preferred embodiment of the present invention;
4 is a photograph showing a state in which the prefabricated greenhouse of FIG. 1 is installed and constructed while covering the upper space of the base structure.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the prefabricated greenhouse according to a preferred embodiment of the present invention is installed while covering one side of the building, and a space for enabling plant cultivation and research in the building is provided integrally. In order to do this, the roof frame 110 has a grid structure and provides a sloping roof function on one side of the upper part of the building, has a trapezoidal grid structure and is configured while supporting the lower portions of both sides of the roof frame 110 and has a side function A three-dimensional structure 100 including a side frame 120 and a lattice structure that provides ) and a plurality of light-transmitting panels 200 that are installed and fixed at the grid positions of the roof frame 110, the side frame 120 and the front frame 130 to cover the interior space and transmit sunlight into the interior space, etc. include

Here, the prefabricated greenhouse may be installed by seating and fixing the three-dimensional structure 100 to the basic structure 10 made of concrete or sandwich panel material installed on one side and the floor of the building more preferably.

The three-dimensional structure 100 is installed while covering one side of the building so that a space for enabling the cultivation and research of plants in the building is provided integrally, and one side of the building through the roof frame 110 By providing a slope at the top, it is possible to facilitate rainwater dripping and maximize the amount of sunlight transmitted.

Here, the roof frame 110 , the side frame 120 , and the front frame 130 are preferably, for example, angular pipes having a cross section of a rectangular cylindrical body, and are first A gasket is positioned, a pair of light-transmitting panels 200 are seated at a predetermined distance on the upper portion of the first gasket, a spacer is filled between the pair of light-transmitting panels 200, and a pair of light transmitting panels ( 200) The second gasket is positioned on the upper surface, and after the clamping bar is positioned on the upper surface of the second gasket, it may have a structure in which the light-transmitting panel 200 is fixedly coupled by bolting to the roof frame.

Therefore, according to the three-dimensional structure 100, through the three-dimensional structure in which the lattice structure and the roof have a slope, the transmission amount of sunlight can be maximized to optimally provide a growth environment for plant cultivation, and a stable structure of the greenhouse is provided. can do.

The light transmitting panel 200 is preferably made of plexiglass having a transparent color and an acrylic material, and when sunlight is transmitted through the outer and inner surfaces, the visible light that promotes the growth of the plant is transmitted more than other visible light. A multi-functional coating layer with a multi-functional coating agent that promotes growth and at the same time emits far-infrared rays that help plants grow to promote plant growth and at the same time absorbs the heat of transmitted sunlight to improve thermal insulation It is preferred that this is configured.

Here, the multi-functional coating agent includes an inorganic binder, a selective sunlight transmitting agent, a polarizing transmitting agent, a far-infrared material emitter, a heat absorber, an anti-degradation agent, and a foreign material remover.

The multifunctional coating agent, more preferably, 50 to 70 parts by weight of the selective sunlight transmitting agent, 30 to 50 parts by weight of the far-infrared material emitter, 30 to 50 parts by weight of the heat absorber, 5 to 15 parts by weight of the deterioration inhibitor to 100 parts by weight of the inorganic binder and 10 to 20 parts by weight of a foreign material remover.

The inorganic binder provides an adhesive function so that a mixture of a selective sunlight transmitting agent, a far-infrared material emitter, a heat absorber, an anti-degradation agent and a foreign substance remover is applied and coated to a predetermined thickness on the transparent panel 200, and is transparent Or it may be a known composition having a translucent color.

Here, 100 parts by weight of the inorganic binder is mixed, and when it is less than the above weight part, it is difficult to secure a thickness for exhibiting a function such as a selective light transmitting agent, and when it exceeds the above weight part, it is discolored when exposed to sunlight for a long time. Since there is a problem in that the appearance is deteriorated due to this occurrence, it is preferable to have a limited weight portion as described above.

The sunlight selective transmitting agent is a material that selectively transmits RGB-based light in sunlight, and may be any one of polymers that transmit only red, green, and blue-based light, respectively, for example, red, green, and blue-based light. In the case of transmitting all of the light, a polymer that selectively transmits visible light at a specific incident angle is included, the polymer has a birefringence property, and the wavelength band of transmitted light may have a wavelength of 400 nm to 800 nm.

Here, the selective sunlight transmitting agent may further include a near-infrared absorbing dye or a fluorescent dye for light conversion, and the like. At least one kind may be selected from the group consisting of azo dyes, anthraquinone dyes, cyanine dyes, and inorganic absorbers, and the fluorescent dye for light conversion is a red dye having fluorescence, and is a yipium compound, 1,10-phenan At least one or more may be selected from the group consisting of tronline and perinene-based compounds.

Therefore, according to the sunlight selective transmittance agent, the light of the RGB wavelength band is intensively transmitted through the plant as described above through the multi-functional coating layer, so that the effect of promoting plant flowering and growth and photosynthesis by the light of the 650 nm wavelength band, which is a red series, is achieved. The effect of accelerating the germination of plant seeds and the growth of roots is provided by the light of the 530 nm wavelength band, which is a green series, and the morphology of the leaves of the plant is promoted by the light of the 420 nm wavelength band, which is the blue series, and leaves are damaged. The effect of growing wide and thick can be provided.

Here, the selective sunlight transmitting agent is mixed with 50 to 70 parts by weight based on 100 parts by weight of the inorganic binder. When it exceeds 70 parts by weight, the light transmittance of the remaining wavelength band of sunlight is lowered, so that the function to sterilize bacteria or bacteria in the soil box where plants are planted is inhibited, and the space inside the greenhouse may have a dark feeling, It is preferable to have a limited part by weight, such as

The far-infrared material emitter is a material that emits far-infrared rays when the light-transmitting panel 200 is heated to a predetermined temperature by sunlight to promote plant growth. For example, manganese dioxide (MnO2) 15-19 wt%, oxidation Chromium (CrO3) 11-18 wt%, cobalt oxide (CoO) 10-15 wt%, cupric oxide (CuO) 3-8 wt%, alumina sol (Al2O3-Sal) 32-45 wt%, and aluminum phosphate (AlPO4) It may be a mixture such as 10 to 20% by weight.

Therefore, according to the far-infrared radiation material, far-infrared radiation is emitted by radiant heat transmitted to the light-transmitting panel 200 to promote plant growth.

Here, with respect to 100 parts by weight of the inorganic binder, 30 to 50 parts by weight are mixed, and when it is less than 30 parts by weight, the amount of far-infrared radiation emitted is lowered to reduce plant growth promotion, and 50 parts by weight In the case of exceeding the part, the amount of far-infrared radiation emitted is sufficient, but the possibility of discoloration of the transparent panel 200 increases, so it is preferable to have the limited weight part as described above.

The heat absorber is a material that absorbs the heat of sunlight transmitted to the light transmitting panel 200 to provide insulation and heat retention, for example, 10 to 15% by weight of silica, 5 to 10% by weight of graphite powder, and isopropyl alcohol ( IPA) may be a mixture of 75 to 85% by weight or the like.

Therefore, according to the heat absorber, heat or radiant heat of sunlight transmitted to the surface of the light transmitting panel 200 can be absorbed to provide insulation and heat retention functions, and thus energy for maintaining temperature conditions for plant growth is saved. can do.

Here, 30 to 50 parts by weight of the heat absorber are mixed with respect to 100 parts by weight of the inorganic binder. When the amount is less than 30 parts by weight, the heat insulation and heat preservation function cannot be maximized, and when it exceeds 50 parts by weight, the light-transmitting panel 200 Since the transparency is lowered, the aesthetic feeling is lowered, and the possibility of discoloration is increased, it is preferable to have a limited weight part as described above.

The anti-degradation agent is a material that inhibits deterioration or discoloration of the multi-functional coating layer composition coated on the surface of the light-transmitting panel 200 by radiant heat of sunlight. For example, it includes rosmarinic acid, carnosol and carnojic acid, And the total content of carnojic acid is 4% by weight or more, and the weight ratio of rosmarinic acid to the total content of carnosol and carnojic acid may be a mixture of 1/2 to 1/30.

Therefore, according to the deterioration inhibitor, the multifunctional coating layer composition coated on the surface of the light-transmitting panel 200 is inhibited from being deteriorated or discolored by the radiant heat of sunlight, thereby preventing the deterioration of aesthetics due to discoloration of the light-transmitting panel 200. .

Here, 5 to 15 parts by weight of the deterioration inhibitor are mixed with respect to 100 parts by weight of the inorganic binder. When the amount is less than 5 parts by weight, the deterioration prevention function is reduced, and when it exceeds 15 parts by weight, the elasticity of the light transmitting panel 200 is increased. Since the degree is lowered and the possibility of being easily damaged by an external impact increases, it is preferable to have a limited weight portion as described above.

The foreign material remover is a material that prevents the deterioration of each function of the multi-functional coating layer composition by inhibiting the adsorption of traces such as rainwater or snow or external dust on the surface of the light-transmitting panel 200, for example, an alkali metal 40% by weight of silicate, 35% by weight of phosphoric acid and 35% by weight of a strong base.

Here, the alkali metal silicate is a material that provides durability against external impacts and the like when coated on the light-transmitting panel 200, and prevents a decrease in elasticity of the light-transmitting panel 200 through the same weight% as above, and prevents cleaning or maintenance It is good to provide a certain durability.

In addition, phosphoric acid is an adsorption prevention material that prevents the adsorption of dust in the air when the light-transmitting panel 200 is coated. The above-described weight% ensures the dust-adsorption prevention function of the light-transmitting panel 200 and prevents the absorption of the mixture. It is good to secure a coating layer of a predetermined thickness by improving the stirrability and bonding properties.

In addition, the strong base is a material that allows the dust, etc. adsorbed upon coating on the light-transmitting panel 200 to be easily removed when it comes into contact with air or a rag in the washing process. It is good to suppress discoloration by preventing decay by the protein component in the foreign material.

Therefore, according to the foreign material remover, it suppresses the adsorption of traces such as rain water or snow or external dust on the surface of the light transmitting panel 200, thereby preventing deterioration of each function of the multi-functional coating layer composition, and lowering of aesthetics due to discoloration can also be suppressed.

Here, 10 to 20 parts by weight of the foreign material remover is mixed based on 100 parts by weight of the inorganic binder. When the amount is less than 10 parts by weight, the function of preventing and removing foreign substances is not maximized, and when it exceeds 20 parts by weight, the transparent panel ( 200), since it is highly likely that the thermal insulation and heat insulation function will be lowered, it is preferable to have a limited weight portion as described above.
