A connecting structure of a special-shaped large-span aluminum alloy grating for a roof is characterized in that the aluminum alloy grating is formed by connecting a plurality of special-shaped profiles between structural main bodies in a crossed mode, the structural main bodies comprise steel structural beams, the special-shaped profiles are fishbone profiles, at most five closed cavities are formed in the fishbone profiles, and the closed cavities are communicated with the steel structural beams. The closed cavity comprises a large circular tube limiting cavity located at the fish head part and a small circular tube limiting cavity located at the fish tail part, the large circular tube limiting cavity and the small circular tube limiting cavity are each internally provided with an arc-shaped clamping groove and a T-shaped abutting plate which are used for being connected with a circular tube in a clamping mode, and the T-shaped transverse part of each T-shaped abutting plate abuts against the outer wall of
