In other words, the support assembly 1 comprises s support bars 101, s being equal to na, where n is equal to 2. The first supporting bar 101 and the third supporting bar 101 of the supporting assembly 1 are connected through the reinforcing rib 102 of one supporting unit 10, the second supporting bar 101 and the fourth supporting bar 101 of the supporting assembly 1 are connected … … through the reinforcing rib 102 of the other supporting unit 10, the s-3 supporting bar 101 and the s-1 supporting bar 101 of the supporting assembly 1 are connected through the reinforcing rib 102 of the first supporting unit 11, and the s-2 supporting bar 101 of the supporting assembly 1 are connected through the reinforcing rib 102 of the second supporting unit 12.
