PURPOSE: An improved frame structure for plastic greenhouse is provided to facilitate the attachment of frames without the use of fastening units, and to prevent a plastic material from drooping by snow, rain, and wind. CONSTITUTION: A plurality of arch-shaped longitudinal supports(10) are fixed on the ground. A plurality of transversal supports(20) are vertically fixed to and installed on the arch-shaped longitudinal supports. The ends of the transversal supports include a fixing ring(22) with the same inner diameter as the outer diameter of the arch-shaped longitudinal supports to be inserted into the longitudinal supports. One end of the transversal support is formed as an insertion ring(24) whose inner diameter is the same as the outer diameter of the longitudinal support. |
