The present invention relates to a plastic greenhouse including a truss assembly (1000) and a windbreak wall assembly (2000). The truss assembly (1000) comprises a top chord (1100), a lower chord (1200), a bracing member (1300) and a first fastening unit (1400), wherein the first fastening unit (1400) connects the top chord (1100) and the bracing member (1300), and the lower chord (1200) and the bracing member (1300) to form a truss structure. The windbreak wall assembly (2000) comprises a vertical member (2100), a windbreak wall member (2200), a diagonal member (2300) and a second fastening unit (2400), wherein the second fastening unit (2400) connects the lower part of the vertical member (2100) and the diagonal member (2300), and the windbreak wall member (2200) and the diagonal member (2300) to reinforce the windbreak wall assembly (2000) structure. The present invention improves the convenience in installation of a truss assembly (1000) and a windbreak wall assembly (2000) of a plastic greenhouse.본 발명은 트러스조립체(1000) 및 방풍벽조립체(2000)를 포함하는 비닐하우스에 있어서, 트러스조립체(1000)는, 상현재(1100), 하현재(1200), 사재(1300), 및 제 1 체결부(1400)를 포함하며, 제 1 체결부(1400)는 상현재(1100)와 사재(1300), 및 하현재(1200)와 사재(1300)를 연결하여 트러스 구조를 형성하며, 방풍벽조립체(2000)는, 수직재(2100), 방풍벽 부재(2200), 경사재(2300), 및 제 2 체결부(2400)를 포함하며, 제 2 체결부(2400)는 수직재(2100)의 하부와 경사재(2300), 및 방풍벽 부재(2200)와 경사재(2300)를 연결하여, 방풍벽조립체(2000) 구조를 보강하는 것을 특징으로 하는 비닐하우스에 관한 것이다.본 발명을 통해, 비닐하우스의 트러스조립체(1000) 및 방풍벽조립체(2000) 설치의 용이성을 높인다.
