PURPOSE: A construction method for a plastic greenhouse using an artificial rafter is provided to prevent damage to the plastic greenhouse due to a power, which stands against an external shock, and a strong loading force, by giving elasticity.CONSTITUTION: A big stone or an obstacle is cleared away and a place is evenly hardened. In the evenly hardened place, every one meter interval is indicated using a line on four edges of a whole area, and a farmland is blasted in 30 cm from the ground floor as an area of an element part. The farmland is blasted in a region of the front gateway and the rear gateway of the plastic greenhouse. A fixing pillar is immediately installed in the region of the front gateway and the rear gateway. In the fixing pillar, a standing line is connected to the fixing pillar which is installed in a region of a rear door by passing from a front rafter to a rear rafter. The rafter is installed in the element part which is installed firstly in a zigzag shape. The rafter is fixed in a standing line using a steel wire after confirming levelness with a horizontal machine. A plastic film fixing pad is installed in left and right sides and front and rear sides of a place where the rafter has installed. A gate door is installed in the region of the front gateway and the back gateway. A plastic film is fixed by the plastic film fixing pad. A light-shielding layer is installed as a heat insulating cover.COPYRIGHT KIPO 2013[Reference numerals] (AA) Implement bed excavation which clears away big stones or obstacles and evenly hardens a place (BB) Step (a) (CC) Implement excavation of an element part installation area which marks 1m intervals using lines on an edge of a rectangular in the whole area of the evenly hardened place and excavates the ground amounting to the area of element parts down to 30cm from the ground surface (DD) Step (b) (EE) Implement rafter fixing pillar and rafter fixing line installation which excavates the ground in front and rear ga
