All of the suggestions I've seen in this thread (Fig. 103, Unistrut clamps, etc.) are good offerings, but don't forget, those things are not listed, so to use them legitimately they need an engineer's certification, as per Section 9.1.1.2 of NFPA 13-2013.
Unless you can get an Eng. Cert. for it, I would avoid the riser clamp idea. A deluge system will develop some healthy thrust forces up and down the length of the main, which could bend the vertical support rods.
