发明名称 Covering structure for agricultural greenhouse, has set of poles defining body formed of six longitudinal and transversally traversed naves and dual front transversal cables connecting top of each of poles to nearby poles
摘要 <p>The structure has a set of poles (2, 3, 4, 5, 6, 7) defining a body formed of six longitudinal and transversally traversed naves (A, B, C, D, E) and dual front transversal cables connecting the top of each of the poles to nearby poles. The cables form a supporting frame for a thread or sheet cover, where the slope of the frame is larger then the slope of a nave which is spaced away from a longitudinal median plane (M) of the body.</p>
