Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a greenhouse skeleton main structure. Background Art

[0002] Greenhouses are common equipment in agricultural planting. They use film to cover the outside to maintain the internal temperature, promote long-term stable growth of crops, and thus achieve the goal of off-season planting. When building a greenhouse, a skeleton structure is needed to effectively support the film. Since the film is made of plastic material, it has the characteristics of thermal expansion and contraction. When the temperature is high during the day, the film will stretch and wrinkle due to thermal expansion, affecting sunlight exposure and being unfavorable for plant growth. At night, the film will shrink due to cold contraction and produce a large force, which may cause the film to break. For this reason, we propose a greenhouse skeleton main structure.
