A kind of greenhouse activity shading web frame,It includes: a greenhouse structure,Several shading nets,One driving device and several gearing wireropes,Wherein,When several shading net configuration what greenhouse structures,System respectively sequentially across set on what,Lower limit wirerope,And it is surround being connected by power for concatenation and driving device by wirerope is interlocked,With reach shading net unfolding,The actuation folded,And those shading net systems sequentially respectively across set on what,Lower limit wirerope,Make shading net system mutually stagger present it is one high and one low on,Lower layer's state,And make the ventilation space with interval between each shading net,To increase ventilation effect when shading net unfolding shading,Greenhouse structure person with preferable planting environment.一種溫室活動遮光網結構，其包含：一溫室結構、若干遮光網、一帶動裝置以及若干連動鋼纜，其中，若干遮光網配置於溫室結構時，係分別依序跨設於上、下限位鋼纜，並受連動鋼纜的環繞串接以及帶動裝置之動力連接，以達到遮光網展開、收合之作動，而該些遮光網係依序分別跨設於上、下限位鋼纜，使遮光網係相互錯開呈現一高一低之上、下層狀態，並使各遮光網間具有間隔之透氣空間，以增添遮光網展開遮光時的通風效果，具有較佳栽培環境之溫室結構者。
