The invention provides a large-span concave fish belly type double-slope roof truss and an installation method thereof. The large-span concave fish belly type double-slope roof truss comprises a lighttruss area, reinforced truss units and overhanging truss units. The light truss area is arranged at the middle position of the roof truss and comprises a plurality of concave fish belly type light truss units arranged parallelly, the reinforced truss units are longitudinally arranged on two sides of the light truss area, and the overhanging truss units are arranged on the periphery of the roof truss. Latticed columns are used as a tubular stand column type, a main truss lower chord is molded into an arch-shaped main truss, a lower chord rod is in an arch shape, secondary trusses are monolithic trusses, the main truss and the secondary trusses are distributed reasonably, and the strength is guaranteed. Compared with a general fish belly type truss, the large-span concave fish belly type double-slope roof truss has a close structure and an opposite molding, on the basis of the common main truss, the secondary trusses are connected crosswise through upper and lower connection rods, an integrated fish belly type double-slope roof truss structure is formed, two ends are thick and heavy, and the middle is thin and light. The concave fish belly molding of the whole truss can be controlled according to sizes and lengths of triangular trusses at the two ends of the secondary trusses and middle monochords.

The invention discloses an ancient wood building repairing construction method which comprises the following steps: (a) performing scene investigation; (b) erecting a scaffold; (c) reinforcing a wood structure; (d) performing wood structure preservative treatment; (e) performing fireproof treatment on the wood structure; (f) performing field arrangement; (g) performing wood structure engineering acceptance. According to the method disclosed by the invention, the current situation in which the wood structure is positioned can be comprehensively mastered, the ancient wood building is subjected to reinforcement and protection through overall reinforcement and single wood reinforcement, the stress performance of the wood structure is improved under the condition that the original structure is not damaged, overall design of the ancient wood building is guaranteed, collapse of the ancient building is avoided, the corrosion resistance of the wood structure is improved due to the wood structure preservative treatment, the safety performance of the wood structure is improved due to fireproof treatment of the wood structure, the service life of the ancient building is prolonged, the aesthetic property of the ancient building is improved, and the method has obvious social and economic values.
