[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 In this embodiment of the utility model, a silicon-based polystyrene composite antique-style flying rafter eaves system includes a support frame. Multiple sets of eaves 1 are installed on the top of the support frame. A bottom sheath 2 is laid on the top of the multiple sets of eaves 1. Multiple sets of flying eaves 3 extending to the outside are installed at the bottom eaves of the bottom sheath 2 by fasteners. A layer of heat insulation and fireproof layer 4 is laid on the multiple sets of flying eaves 3 and the bottom sheath 2. A layer of waterproof layer 5 is coated on the top of the heat insulation and fireproof layer 4. Drip tiles 6 are stacked on the top of the waterproof layer 5. A large connecting eave 7 supporting the bottom drip tiles 6 is provided at the bottom of the flying eaves 3.

[0016] When assembling the antique-style flying rafter eaves system, the components are assembled one by one from the bottom structure of the building upwards. Multiple sets of eaves rafters 1, bottom sheathing 2, multiple sets of flying eaves 3, and drip tiles 6 are assembled to achieve an antique-style appearance. The traditional wooden building structure enhances the aesthetics and provides good roof drainage. Furthermore, the top of the antique-style flying rafter eaves system is equipped with a thermal insulation and fireproof layer 4 and a waterproof layer 5, which further enhances the external waterproof and fireproof performance of the antique-style flying rafter eaves system.

[0017] In one embodiment, the supporting frame includes a main column 8 and an eaves column 9 serving as bottom support. A crossbeam 10 is installed between the main column 8 and the eaves column 9. A frame beam 11 supporting multiple sets of eaves rafters 1 is installed on the top of the main column 8. A head beam 12 supporting multiple sets of eaves rafters 1 is installed on the top of the eaves column 9. One end of the head beam 12 is connected to the main column 8. The multiple sets of beams and columns can provide high-strength and stable support for the roof.

[0018] Among them, the main column 8 and the frame beam 11 are connected by mortise and tenon structure, and the head beam 12 and the eaves column 9 are connected by mortise and tenon structure, which facilitates a highly stable connection between wooden structures and does not easily damage the structural strength of the wood itself.

[0019] Correspondingly, the top of the beam 11 is connected to the first truss 18 via the inserted first rafter plate 13, and the top of the end beam 12 is connected to the second truss 15 via the inserted second rafter plate 14. This provides a stable positioning support for the top eaves rafters 1. The tops of the end beam 12 and the beam 11 are provided with grooves for accommodating the trusses, which can be used to improve the stability of the assembly between the end beam 12, the beam 11 and the trusses, and help improve the overall seismic resistance of the building structure. The first rafter plate 13 and the second rafter plate 14 are both inserted into the bottom sheath 2, which facilitates high-strength connection between the wooden structures.

[0020] In one embodiment, the fastener includes a small connecting rafter 17 installed at the bottom top of the bottom sheath 2, which can provide lifting support for the eaves rafter 1. The small connecting rafter 17 is provided with a gate baffle 16 for the eaves 3 to be snapped and positioned. The bottom of the eaves 3 is provided with a slot for the gate baffle 16 to be inserted. The gate baffle 16 facilitates the assembly between wooden building components.

[0021] Among them, the thermal insulation and fireproof layer 4 is a silicon polystyrene board. The silicon polystyrene board has good thermal insulation, fire resistance, water resistance and moisture resistance. At the same time, the silicon polystyrene board has high tensile and compressive strength and is relatively light in weight. Its performance in all aspects is superior. The waterproof layer 5 is a polymer modified bitumen waterproof coating. The polymer modified bitumen waterproof coating is applied to the thermal insulation and fireproof layer 4, which can easily further improve the waterproof effect of the building roof.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
