Figure 1 The greenhouse shown has a main frame consisting of columns A, beams B, arches C, and longitudinal bars D. In the longitudinal direction, columns A of the same height are arranged in rows from front to back. The two ends of the longitudinal bar D are connected to the tops of two adjacent columns A. In the transverse direction, the two ends of the beams B are connected to the tops of two columns A in the same row.

[0030] The use process of the greenhouse arch support device provided in the embodiment is as follows:

[0031] According to the size of the arch 01, the length of the required beam 1 is calculated (when the beam 1 is installed on the upper part of the arch 01, the first end of the beam 1 and the chord midpoint between the two ends of the circular arch top of the arch 01 are connected, and the second end of the beam 1 and the chord midpoint between the two ends of the circular arch top of the arch 01 are connected, the included angle between the two is 85°-95°, the length of the beam 1 in this position is the length of the required beam 1), and the installation height of the beam 1 is determined, then the length of the second support pipe 102 inserted into the first support pipe 101 is adjusted to the appropriate length, and the first support pipe 101 and the second support pipe 102 are fixed by the locking bolt 103, that is, the length of the beam 1 is adjusted, then the first end of the first support pipe 101 is fixed on the first side of the arch 01 by the first clamp 201, and the second end of the second support pipe 102 is fixed on the second side of the arch 01 by the second clamp 301, that is, the installation of the beam 1 is completed, as shown in Figure 3 Each arch 01 of the circular-arch-shaped greenhouse 02 is provided with a beam 1, which ensures the stability of the overall structure of the greenhouse.
