The prefabricated roof panel 2 is a prefabricated pouring part, and the tensioning piece 17 corresponding to the position of the through hole 15 is arranged on the bottom of the prefabricated roof panel 2 and the bottom of the outward bending part 16.

[0039] Reference Figure 4 The schematic diagram of the prefabricated roof steel frame 1 and the prefabricated roof panel 2 connection, one end of the tension member 17 is embedded in the prefabricated roof panel 2, the other end is inserted into the through hole 15, and is locked and fixed through the tension nut 18.

[0040] In the above embodiment, the prefabricated roof steel frame and the roof panel are the basic prefabricated components, the module is uniform, the installation is convenient, and the whole assembly of the roof structure is realized. The structure of the prefabricated roof panel 2 is inspired by the style of traditional Chinese architecture, and the end has an arc-shaped structure similar to the end of a tile. On the one hand, it provides protection for the connection of the prefabricated roof steel frame 1, which is beneficial to the drainage and waterproof function of the roof. On the other hand, the prefabricated roof has more traditional national characteristics, which is suitable for the construction of large-span roof structure, suitable for homestay building, old house reconstruction, garden building, etc., so that the building roof has distinct traditional national characteristics, thus achieving the purpose of the embodiment.

[0041] As a preferred technical solution of the embodiment, the through hole 15 of the prefabricated roof steel frame 1 is a vertical waist-shaped hole, which is convenient for leaving a vertical margin for corresponding adjustment during installation.
