The present invention relates to a plastic greenhouse to prevent snow accumulation, which includes an inclined surface of a roof of a plastic greenhouse formed in a prescribed angle range to prevent snow accumulation on the upper surface of the plastic greenhouse, to prevent the collapse of the plastic greenhouse by heavy snow in a winter season and harm to human life and property stemming from the collapse of the plastic greenhouse. More specifically, the plastic greenhouse to prevent snow accumulation comprises: a frame (10) comprising a vertical pipe (11), a first horizontal pipe (12), a second horizontal pipe (13), a first inclined pipe (14), a second inclined pipe (15), and a middle pipe (16) a binding member (20) having a plurality of branching portions formed thereon and binding the pipes of the frame (10) to each other and a fixing member (30) to fix the vertical pipe (11) on the ground. A plastic film covers the outer surface of the plastic greenhouse. The binding member (20) comprises first to fourth binding members (21, 22, 23, 24) corresponding to branching locations branching from the frame (10) and branching off into a fixing branching portion (25) and a variable branching portion (26). The fixing branching portion (25) is formed in a cylindrical shape, and the vertical pipe (11), the first horizontal pipe (12), the second horizontal pipe (13), and the middle pipe (16) are mounted and fixed on the fixing branching portion (25). The variable branching portion (26) is formed in a fan shape having an elliptic cross section, and the first inclined pipe (14) and the second inclined pipe (15) are mounted on the variable branching portion (26) to be able to change an angle to change an inclination angle.COPYRIGHT KIPO 2016본 발명은 적설 방지 비닐하우스에 관한 것으로, 비닐하우스의 상면에 눈이 적층되지 않도록 일정 각도 범위에서 형성되는 경사면의 지붕이 구비된 비닐하우스를 구성함으로써 겨울철 폭설에 의한 비닐하우스의 붕괴와 그로 인해 파생되는 인명 및 재산 피해를 예방하도록 하는 적설 방지 비닐하우스에 관한 것이다.보다 상세하게는 수직관(11), 제1수평관(12), 제2수평관(13), 제1경사관(14), 제2경사관(15), 중심관(16)으로 이루
