Double-membrane dense rib hollow arched shed plate and arched shed for vegetable greenhouse

Abstract

The utility model discloses a double membrane dense rib hollow arched shed board for vegetable greenhouse, including the hollow arched shed board main body of intermediate layer longitudinal bending, be provided with the outer layer light transmission film on the outer circle of hollow arched shed board main body and be provided with the inner layer light transmission film on the inner circle. The utility model adopts the arched shed board replacement steel reinforced keel, thereby makes the whole to light transmission film supporting capacity better, makes the vegetable greenhouse in bending -resistant, compression -resistant and deformation -resistant ability has obtained the great enhancement, can effectively resist strong wind, heavy rain and snow load simultaneously, avoids the problem that traditional plastic film because of ponding snow and subsides, deforms even leads to the shed body collapse, adopts the design of dense rib type structure and hollow block simultaneously, greatly alleviates the overall weight and reduces the material cost.
