[0034] Please refer to Figures 1 to 8 The present application provides a purlin reinforcing structure and a steel structure roof with the same.

[0035] Specifically, please refer to Figure 1 and Figure 2, the steel structure roof comprises steel beams 60, the steel beams 60 are arranged in a plurality of rows in the longitudinal direction. A purlin reinforcing structure is arranged on the upper side of the plurality of steel beams 60, and specifically comprises a plurality of first purlins 10 and second purlins 20 and a plurality of tie rods 30 arranged between the first purlins 10 and the second purlins 20.
