The present invention relates to manufacture of a plastic greenhouse. As a glass greenhouse costs a lot, plastic greenhouses are commonly used. A plastic greenhouse has an economic strength, but the conventional plastic greenhouse mainly relying on cylindrical pipes is weak in the load strength such as accumulated snow on the roof, and has a weak durability problem such as plastic torn by strong wind or typhoon. The present invention is to build a novel building structure for a plastic greenhouse which is stronger than the glass greenhouse by supplementing the weakness in a building structure of a plastic greenhouse, and is designed to have plastics to endure in typhoon or heavy snow while the fabrication cost is similar to the conventional plastic greenhouse contrary to the glass greenhouse in an economic aspect. In order to solve the problems, the present invention uses wires, L-shaped steel or T-shaped steel or H-shaped steel, and straight joints. A high-story plastic greenhouse in a polygonal cone type dome shape is able to be manufactured by using multiple straight joints. Frequent typhoon and heavy snow due to the climate change worldwide impact in agriculture and food production. As such, the importance of greenhouse cultivation is expected to grow. The fabricating method of plastic greenhouse according to the present invention is expected to assist in improving the agricultural productivity. |
