[0024] A hook is installed on the top, when the support rod 4 does not need to be reinforced, the support rod 4 can be separated from the support seat 5, the support rod 4 is rotated upward and fixed on the hook. The support rod 4 is a metal rod.

[0025] The top frame assembly further comprises a plurality of top keels 3, and the top beam 2 is connected to the top keels 3 in the middle part. The plurality of top keels 3 are distributed at intervals along the width direction of the roof of the greenhouse, and the length direction of the top keels 3 is consistent with the length direction of the greenhouse. Adjacent two top keels 3 are fixed through a transverse beam or a keel structure at the end of the greenhouse, and the top keels 3 form a support framework at the top of the greenhouse, and the film cloth 1 is laid on the upper end of the support framework.

[0026] The top beam 2 is located on the center line of the greenhouse, and is flush with the top keel 3 or located below the top keel 3. When the top beam 2 is located below the top keel 3, the top beam 2 and the top keel 3 are fixed by a longitudinal connecting beam. The support assembly is used to strengthen the support performance of the top beam 2, so as to avoid the greenhouse from being collapsed by accumulated snow. When the top beam 2 is flush with the top keel 3, the top beam 2 is in contact with the tarpaulin of the greenhouse roof, and the connecting point of the support assembly needs to avoid the fixing point of the tarpaulin and the top beam 2. The position where the support rod 4 is hinged to the top beam 2 is located at the lower end of the top beam 2, and the support rod 4 does not contact the film cloth in the process of rotation, so as to avoid that the support rod 4 scratches the film cloth.
