Plastic greenhouse support structures having excellent structural stability are provided to prevent snow accumulation, withstand strong winds and to ensure excellent heat conserving effect by covering with plastic films in an overlapped manner. Plastic greenhouse support structures(1) comprise: a pair of support frames(10) fixed to the ground in an upright state and connected to an outside support rod(11) and an inside support rod(17); steel wire(20) inserted into wood of the support frames on both ends and connecting the support frames; a mesh net(30) fixed to the steel wire; and a plurality of strings(40) connected to the support frames on one end and fixed to the ground on another end. The lower part of the support frames is formed at an obtuse angle wider than an arch type. |
