The present invention relates to a structure which is more quickly and simply installed, secures strong binding power, and can perform a safe support function during the installation of a high bed (a culture medium for plant cultivation) allowing the cultivation in a place higher than the ground in a plastic greenhouse. According to the present invention, a vertical support (10) and a horizontal support (20), which constitute the structure used for installing the high bed in the plastic greenhouse, are composed of a rail-type high strength square frame (P). The frame is bent in multiple steps in a square shape and has a fixed size of hollow groove (P-1) formed on the inner part. A rail groove (P-3) cut long in a longitudinal direction is formed on one side of the outer circumferential surface of the frame. Furthermore, binding support parts (P-4) are bent inwards from both sides of the rail groove (P-3). The other three sides of the outer circumferential surface of the frame comprise at least one reinforcing bent part (P-2) compression-molded in a concave or convex shape. A slide control-type binding means (100) which has a binding structure linked to the binding support parts (P-4) is bound inwards from both sides of the rail groove (P-3) in a 90º counterclockwise or clockwise rotated T-shaped binding requirement part (K), where the vertical support (10) and the horizontal support (20) touch each other. |
