The present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0034] As Figures 1 to 3 shown, the present invention provides a ventilated roof structure. The overall ventilated roof structure is a hyperbolic structure that is high in the middle and low on both sides. Any one of the curved surfaces includes a plurality of roof unit structures 110 and a plurality of aluminum strip ceilings 130 installed in cooperation with the roof unit structures 110;

[0035] Any one of the roof unit structures 110 is in an overall four-point structure, including corner point A, corner point B, corner point C, and corner point D. Among them, corner point A and corner point B are the same-side points close to the middle of the overall ventilated roof structure 110;

[0036] Corner point A is higher than corner point B, corner point C, and corner point D;

[0037] The roof unit structure 110 and another adjacent roof unit structure 110 form a triangular skylight.

[0038] Based on the above characteristics, on a summer night with the air conditioner turned off, open the ventilation structure in the building (such as Figure 4 , the elevation window shown in Figure 5) and the triangular skylight, so that the cold air coming down from the mountain can enter from the ventilation structure (such as Figure 4, the hot air inside the building enters the building through the elevation window shown in Figure 5 and is discharged through the triangular skylight, achieving the effect of quickly cooling the building interior.

[0039] During the day, the eaves formed by the highest corner point A can block sunlight, avoiding the problem of indoor exposure to the sun, thus preventing the indoor temperature from rising due to sun exposure and improving indoor comfort.

[0040] As Figure 1 shown, the figure includes two curved surfaces, each curved surface includes 3×4 roof unit structures 110, combined with Figure 2 , point A of each tree-shaped support unit 112 is connected to points B, C, and D of adjacent tree-shaped support units 112 through a vertical connecting rod 140.

By changing the size of the steel column 120 to adjust the height, the modular design of the roof unit cover 111 and the tree-shaped support unit 112 is convenient for installation and replacement, reducing the maintenance cost.

[0043] Any one roof unit cover 111 covers the corresponding tree-shaped support unit 112, and the aluminum strip ceiling 130 is arranged below the tree-shaped support unit 112.

[0044] In this embodiment, the tree-shaped support unit 112 provides a stable support for the roof unit cover 111, enhancing the overall stability and load-bearing capacity of the roof; the tree-shaped support unit 112 has a unique design combined with the roof unit cover 111 to form an aesthetic visual effect; the aluminum strip ceiling 130 is arranged below the tree-shaped support unit 112, having heat insulation and heat preservation functions, which helps to adjust the indoor temperature during the day and improve the energy efficiency of the air conditioner.

[0047] In an embodiment of the present invention, preferably, the tree-shaped support unit 112 includes 8 frames of "rice"-shaped triangular planar trusses.

[0048] Among them, the "rice"-shaped triangular plane truss provides high structural stability and strength, helps to evenly transfer the roof load to the lower structure, and reduces local force concentration; through the "rice"-shaped layout, space can be preferentially utilized to provide a larger open area and fewer support structures for the building.

[0054] In this embodiment, the triangular stable structure formed by the main truss 160 and the secondary truss 180 can significantly improve the stability of the entire structure by utilizing the inherent stability of the triangle; the main truss 160 can effectively transfer the load from the upper structure to the lower support structure, and the secondary truss 180 further disperses the load to improve the overall load-bearing capacity of the structure.

[0055] In an embodiment of the present utility model, any vertical connecting rod 140 is parallel to the steel column 120;

[0056] Any vertical connecting rod 140 connects the edge sealing beams 150 of four adjacent tree-shaped support units 112.

[0057] Figure 4, Figure 5 shows an application example of the present invention. Since Bazhong is located south of the Qinling - Huaihe River north - south dividing line in China, it neighbors Dazhou in the east, Nanchong in the south, Guangyuan in the west, and Hanzhong in Shaanxi in the north. It belongs to a typical mountainous area around the basin. The terrain is high in the north and low in the south, sloping from north to south. The highest altitude is 2507.0 meters at Guangwu Mountain in Nanjiang County in the northwest; the lowest altitude is 268.3 meters at Huangmeixi in Pingchang County in the south, with a height difference of 2238.7 meters. It has a humid subtropical climate with distinct seasons, and its climate characteristics are greatly affected by the terrain. Summer is the season with the highest energy consumption in Bazhong City. By taking advantage of the environmental conditions and through ventilation design, we can utilize the cool terrain wind on the north side of the mountain at night in summer to cool down Bazhong East Station located in the valley.

[0058] As Figure 4 shown, during the day in summer, by using the deep overhang on the south side and the overhang of the triangular skylight, the direct sunlight during the day can be blocked. Close the ventilation structure (such as the elevation window shown in Figure 4 , Figure 5) and the triangular skylight, and cool down through the indoor air - conditioning cycle; as Figure 5 shown, at night in summer, open the ventilation structure (such as the elevation window shown in Figure 4 , Figure 5) and the triangular skylight. Utilize the cool downhill wind on the north side of the mountain to enter the room through the north - side ventilation structure (such as the elevation window shown in Figure 4 , Figure 5), and take the hot air in the room out through the triangular skylight, so that the air circulates to achieve the purpose of reducing the indoor temperature.

[0059] The above - mentioned is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
