The present invention relates to a vinyl greenhouse structure. The vinyl greenhouse is formed by covering, with a vinyl sheet, a frame structure formed by a horizontal joining frame (200) which joins, in a horizontal direction, a plurality of arch-type frames (100) in the shapes of arcs arranged at intervals to be separated along both sides of the arch-type frames (100). An arrangement area of the arch-type frames (100) forming the total length of the vinyl greenhouse (10) is divided into first (S1), second (S2) to N (SN) areas. The vinyl greenhouse is installed to have the same height of the arch-type frames (100) installed in the same area (the first, second, or N area) forming each area. Ventilation holes (20-1, 20-2 to 20-N) are formed as a step (h) for each area is formed in the first (S1) area to the N (SN) area. Air from the outside enters through the ventilation holes (20-1, 20-2 to 20-N) formed by the steps (h), passes through an upper end portion of the inside of the vinyl greenhouse (10), and induces air at high temperatures in the vinyl greenhouse (10) to be discharged to the outside. An effect of significantly reducing installation costs can be expected as the vinyl greenhouse frame structure with a comparatively simple structure is provided. The present invention relates to the vinyl greenhouse having a multi-stage ventilation structure frame which inserts external air into the vinyl greenhouse and discharges internal air in a smooth manner and thus increases efficiency of ventilation and is expected to have an effect of preventing excessive maintenance and repair work and reducing costs for maintenance and repair after installation.COPYRIGHT KIPO 2018본 발명은 다수개 등간격 이격 배치되는 원호상의 아치형골조프레임(100)들의 양측면을 따라 수평상 연결하는 수평연결프레임(200)에 의해 이루어지는 골격 구조물에 비닐을 커버하여서 되는 비닐하우스 구조에 있어서, 비닐하우스(10)의 전체 길이를 이루는 상기 아치형골조프레임(100)들의 배치 영역을 제1(S1),제2(S2)..제N(SN) 영역으로 구분하고, 상기 각 영역을 이루는 동일 영역(제1영역 또는 제2영역 또는 제N영역)내에 설치되는 아치형골조프레임(100)들의 높이(H)는 동일하게 이루어지며 설치되어지되, 상기 제1영역(S1)으로 부터
