Disclosed is a plastic film fixing pad-integrated rafter for a plastic film greenhouse, in which a plastic film fixing pad that fixes a plastic film of the plastic film greenhouse is integrally formed with a rafter frame to facilitate the construction of rafters, and it is possible to maintain rigidity of the rafter without being crushed even when the same is bent roundly. The present invention comprises: the plastic film fixing pad in which vertical walls are erected on both sides to form a plastic film accommodating space therein, the lower ends of the vertical walls are connected by horizontal plates, a first bent part bent inward is formed on the upper side of the vertical walls so that a step protruding inward is formed at the upper ends of the vertical walls, and a second bent part bent outward is formed to face the first bent part; the rafter frame in which a support plate is formed by extending an outer wall downward from the second bent part of the plastic film fixing pad part to face the outer surface of the vertical walls and then horizontally bending the same inward from the lower end of the vertical walls, locking plates are formed by bending vertically upward from the end of the support plate so that an insertion space is formed between the locking plates, wherein the outer wall is formed with a concave part having an upper concave ridge and a lower concave ridge in the middle, and the upper concave ridge is formed to support a part of the bottom surface of the horizontal plates of the plastic film fixing pad; and a clamping member which binds a transverse pipe installed below the rafter frame in a direction orthogonal to the rafter frame with the rafter frame.
비닐하우스의 비닐을 고정하는 비닐고정패드를 서까래프레임에 일체로 형성하여 서까래 시공을 용이하게 하되, 라운드지게 벤딩하더라도 찌그러지지 않고 강성을 유지할 수 있는 비닐고정패드 일체형 비닐하우스용 서까래가 개시된다.
