[0002] The roof structure of a light steel structure house is mainly composed of a steel frame and tiles laid on the frame.
[0003] The prior art discloses a low-energy light steel structure house roof system (publication number: CN220954124U), which includes walls, steel roof trusses, roof components, roof components, reinforcement rods, rain gutters, air inlets and dust nets; the air inlets and roof components are arranged in such a way that air inlets are opened below both ends of the steel roof trusses, and a gap is set between the ends of the roof steel frames that are close to each other for ventilation. Natural ventilation is adopted for ventilation, and no additional ventilation equipment is required, thereby reducing the operating cost of the roof system.
[0004] In the existing technology, a rainproof roof is formed by laying sandwich tiles on a steel structure. However, the use of large-area composite panels increases the overall structural weight of the roof, which goes against the original intention of lightweighting the steel structure. The use of tiles rolled from single-layer plates has good thermal conductivity, which increases the heat exchange between the inside and outside of the house and has poor thermal insulation effect. Therefore, it is difficult to strike a balance between thermal insulation and lightweighting, and there is a certain room for optimization.
[0005] To this end, we propose an environmentally friendly lightweight steel roof structure. Utility Model Content
[0006] The utility model mainly solves the technical problem of the large weight of the composite insulation board when it is laid over a large area, and provides an environmentally friendly lightweight steel roof structure.
[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions: an environmentally friendly lightweight steel roof structure, comprising:
[0008] girder, a triangular frame used for support;
[0009] Crossarm, fixedly connected to the beam for lateral limitation;

[0011] The heat insulation board is arranged under the tile and fixedly connected to the cross arm, and a heat insulation interlayer for heat insulation is formed between the tile and the heat insulation board. The top of the tile is provided with a ventilating hole for ventilation of the heat insulation interlayer;
[0012] The shielding component is arranged in the vent hole and is used to form a barrier above the vent hole.
[0013] As a preferred embodiment of the present invention, the shielding assembly includes an exhaust pipe and a rain shield. The exhaust pipe is located in the air vent and fixedly connected to the tile. The rain shield is arranged above the exhaust pipe.
[0014] As a preferred embodiment of the present invention, the exhaust pipe forms a tubular structure with two ends open, the lower end of the exhaust pipe extends into the thermal insulation interlayer, and the upper end of the exhaust pipe extends above the tile.
[0015] As a preferred embodiment of the present invention, the shielding assembly further includes a horizontal rod and a support column, the horizontal rod is fixedly connected to the exhaust pipe, and the rain shield is connected to the rain shield via the support column.
[0016] As a preferred embodiment of the present invention, the horizontal rod forms a rectangular rod structure, the horizontal rod is fixedly connected to the upper end face of the exhaust pipe, the support column is fixedly connected to the top of the horizontal rod, the lower end face of the rain shield is fixedly connected to the top face of the support column, and a gap is left between the rain shield and the exhaust pipe port.
[0017] As a preferred embodiment of the present invention, the rain shield forms a truncated cone structure, the end face of the rain shield with a larger diameter faces the exhaust pipe, and a notch is provided at the bottom of the rain shield to form a hollow structure.
[0018] As a preferred embodiment of the present invention, the bottom of the insulation board is flush with the bottom of the cross arm, and an insulation board is arranged between two adjacent cross arms to form a thermal insulation interlayer between the top surface of the insulation board and the bottom surface of the tile.
[0019] The utility model provides an environmentally friendly lightweight steel roof structure. It has the following beneficial effects:
[0020] 1. This environmentally friendly lightweight steel roof structure forms an insulation interlayer by arranging tiles and insulation boards. The air between the insulation interlayer is used to suppress heat from being directly conducted to the indoor space below the insulation board. The tin foil adhered to the bottom of the tiles serves as a reflective layer to suppress heat transfer after the insulation board is heated by the sun. With the ventilation holes opened, when the air in the insulation interlayer is heated, the hot air will rise due to its density. By discharging the hot air in the insulation interlayer into the outside air through the ventilation holes, the heat accumulation in the insulation interlayer is suppressed, thereby achieving insulation. Compared with the thick insulation filling layer in the prior art, this solution has the characteristics of simple structure and small weight, which is more in line with the needs of energy saving and environmental protection.
[0021] 2. This environmentally friendly lightweight steel roof structure is equipped with an exhaust pipe, which is locked to the tiles by bolts, and the air vents are opened at the ridge line position on the top of the tiles. By coating the outer wall of the exhaust pipe with waterproof glue, the inverted bowl-shaped rain shield can prevent rainwater from entering the thermal insulation interlayer through the air vents. At the same time, the exhaust pipe extending above the tiles can increase the pressure difference between the thermal insulation interlayer and the outside air, promote the discharge of hot air in the thermal insulation interlayer to achieve the purpose of ventilation.
[0022] 3. This environmentally friendly lightweight steel roof structure is supported and fixed by setting horizontal rods and support columns, so that an open space for air flow is formed between the rain shield and the upper port of the exhaust pipe, which promotes the flow and diffusion of hot air discharged from the exhaust pipe into the outside atmosphere. On the basis of realizing that the rain shield shields the exhaust pipe port from rain, it will not affect the discharge of hot air in the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] An environmentally friendly lightweight steel roof structure, such as Figure 1 、 Figure 2 and Figure 3 as well as Figure 4 As shown, including:
[0030] Girder 10, a triangular frame for support;
[0031] Cross arms 11 are fixedly connected to the beams 10 for lateral positioning. A plurality of beams 10 and cross arms 11 are provided and mutually locked by bolts to form a roof frame.
[0032] Tiles 12 are laid on top of the crossarms 11 to prevent rain. Multiple tiles 12 are laid on the crossarms 11 to form a rainproof top surface. The tiles 12 are locked to the crossarms by bolts.
[0033] The heat insulation board 13 is arranged below the tile 12 and fixedly connected to the cross arm 11. A heat insulation interlayer 20 for heat insulation is formed between the tile 12 and the heat insulation board 13. The top of the tile 12 is provided with a ventilating hole 21 for ventilation of the heat insulation interlayer 20. The bottom of the heat insulation board 13 is flush with the bottom of the cross arm 11. An heat insulation board 13 is arranged between two adjacent cross arms 11. The heat insulation interlayer 20 is formed between the top surface of the heat insulation board 13 and the bottom surface of the tile 12;
[0034] In this solution, a thermal insulation interlayer 20 is formed by arranging tiles 12 and insulation boards 13, and the air between the thermal insulation interlayer 20 is used to suppress heat from being directly conducted to the indoor space below the insulation board 13, and the tin foil glued to the bottom of the tile 12 serves as a reflective layer to suppress the heat transfer after the insulation board 13 is heated. In conjunction with the air vents 21 opened, when the air in the thermal insulation interlayer 20 is heated, the hot air will rise due to its density. By discharging the hot air in the thermal insulation interlayer 20 into the outside air through the air vents 21, the heat accumulation in the thermal insulation interlayer 20 is suppressed, thereby achieving insulation. Compared with the thick insulation filling layer in the prior art, this solution has the characteristics of simple structure and small weight, which is more in line with the needs of energy saving and environmental protection.
[0035] like Figure 3 and Figure 5 As shown, the shielding component is arranged in the vent hole 21 to form a barrier above the vent hole 21;
[0036] The shielding assembly includes an exhaust pipe 30 and a rain shield 31. The exhaust pipe 30 is located in the air vent 21 and is fixedly connected to the tile 12. The rain shield 31 is arranged above the exhaust pipe 30. The exhaust pipe 30 forms a tubular structure with both ends open. The lower end of the exhaust pipe 30 extends into the thermal insulation interlayer 20, and the upper end of the exhaust pipe 30 extends above the tile 12. The rain shield 31 forms a frustum structure, with the larger diameter end surface of the rain shield 31 facing the exhaust pipe 30. The bottom of the rain shield 31 is provided with a notch to form a hollow structure.
[0037] Due to the provision of the air vents 21, rainwater will enter the thermal insulation interlayer 20 from the air vents 21 during rainfall. In order to solve this problem, an exhaust pipe 30 is provided, and the exhaust pipe 30 is locked to the tile 12 by bolts, and the air vent 21 is opened at the ridge position of the top of the tile 12. By coating waterproof glue on the outer wall of the exhaust pipe 30, the inverted bowl-shaped rain shield 31 can inhibit rainwater from entering the thermal insulation interlayer 20 from the air vents 21. At the same time, the exhaust pipe 30 extending above the tile 12 can increase the pressure difference between the thermal insulation interlayer 20 and the outside air, thereby promoting the discharge of hot air in the thermal insulation interlayer 20 to achieve the purpose of ventilation.
[0038] like Figure 5 As shown, the shielding assembly also includes a horizontal rod 32 and a support column 33. The horizontal rod 32 is fixedly connected to the exhaust pipe 30. The rain shield 31 is connected to the rain shield 31 through the support column 33. The horizontal rod 32 forms a rectangular rod structure. The horizontal rod 32 is fixedly connected to the upper end surface of the exhaust pipe 30. The support column 33 is fixedly connected to the top of the horizontal rod 32. The lower end surface of the rain shield 31 is fixedly connected to the top surface of the support column 33. A gap is left between the rain shield 31 and the end of the exhaust pipe 30.
[0039] As a supplement to the above solution, by setting a horizontal rod 32 and a support column 33, the rain shield 31 is supported and fixed by the support column 33, so that an open space for air flow is formed between the rain shield 31 and the upper end of the exhaust pipe 30, thereby promoting the hot air discharged from the exhaust pipe 30 to flow and diffuse into the outside atmosphere. On the basis of achieving the rain shield 31 to shield the end of the exhaust pipe 30 from rain, it will not affect the discharge of hot air in the exhaust pipe 30.
[0040] The working principle of the present invention is as follows: a thermal insulation interlayer 20 is formed by arranging tiles 12 and thermal insulation boards 13. The air between the thermal insulation interlayer 20 is used to suppress the heat from being directly transferred to the indoor space below the thermal insulation board 13. The tin foil adhered to the bottom of the tile 12 acts as a reflective layer to suppress the heat transfer from the thermal insulation board 13 after being heated by the sun. In conjunction with the ventilation holes 21 provided, when the air in the thermal insulation interlayer 20 is heated, the hot air will rise due to its density. The hot air in the thermal insulation interlayer 20 is discharged into the outside air through the ventilation holes 21.
[0041] Due to the provision of the air vents 21, rainwater will enter the thermal insulation interlayer 20 from the air vents 21 during rainfall. In order to solve this problem, an exhaust pipe 30 is provided, and the exhaust pipe 30 is locked to the tile 12 by bolts, and the air vents 21 are opened at the ridge position of the top of the tile 12. By coating waterproof glue on the outer wall of the exhaust pipe 30, the inverted bowl-shaped rain shield 31 can inhibit rainwater from entering the thermal insulation interlayer 20 from the air vents 21. The rain shield 31 is supported and fixed by the support column 33, so that an open space for air flow is formed between the rain shield 31 and the upper end of the exhaust pipe 30, thereby promoting the hot air discharged from the exhaust pipe 30 to flow and diffuse into the outside atmosphere.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
