The present invention relates to a vinyl greenhouse. The fundamental difference between a vinyl greenhouse design and a general building design is the vinyl material covering the wall surfaces. The vinyl material has economical advantages of excellent sunlight transmittance and low costs. However, the vinyl material has a disadvantage in that it is easily torn by typhoons and heavy snowfall due to weak tensile strength. However, a glass greenhouse substituted for the vinyl greenhouse is too expensive when considering the realities of farming villages and agricultural competitiveness. The vinyl house of the present invention can be easily fabricated within a similar price range as an existing vinyl greenhouse while using various kinds of shaped steels and wires having excellent flexural strength. Further, according to the present invention, a super high-rise vinyl greenhouse having greater structure strength and durability than a glass greenhouse can be fabricated. The larger the vinyl greenhouse, the higher the thermal efficiency, and thus the vinyl greenhouse of the present invention has an energy saving effect. The development of hydroponics makes farming in the super high-rise vinyl greenhouse possible, and will be among one good method for coping with the global food crisis caused by abnormal climates. |
