The invention discloses a Buddha ceremonial canopy and a manufacturing method thereof. The Buddha ceremonial canopy comprises two column legs and a steel structural triple-bent arch frame. The steel structural triple-bent arch frame successively comprises a front main arch frame, a middle arch frame and a rear main arch frame from front to back, both the front main arch frame and the rear main arch frame are double-bent arch frames, the middle arch frame comprises five vertical double-bent secondary arch frames, three-dimensional diagonal web members are connected between each two adjacent arch frames, and two ends of each arch frame are respectively connected with the two column legs. The manufacturing method of the Buddha ceremonial canopy includes scientifically distributing resources, performing segment processing on members manufacturedby factories, reasonably arranging feeding of components, successively assembling the components in different areas in a field, adopting a mounting scheme of matching of crane tower blocks and high-altitude embedding scattering hanging, and adopting advanced construction technology, technological measures and an improved safety quality management system. The method can effectively resolve problems relevant to construction progress, quality, safety and the like, accurate positioning can be realized, risks during field assembly are reduced, and construction period can be shortened.
