[0007] The roof structure according to embodiments of the present invention has at least the following beneficial effects:

[0008] After rain or snow, snow may accumulate on the sloping roof panels of steel structure factory buildings using the aforementioned roof structure. By controlling the rotation of the sloping roof panels, the tilt angle of the panels can be increased, facilitating the sliding of snow and reducing the risk of the sloping roof panels collapsing, thereby reducing the risk of the entire roof structure collapsing. In addition, during rain or snow, due to the low temperature, ice may form at the junction of the sloping and horizontal roof panels, making it difficult to rotate the sloping roof panels. Before rotating the sloping roof panels, exhaust fans and heating elements can be turned on to blow hot air onto the junction of the sloping and horizontal roof panels, achieving the purpose of thawing and improving the problem of the sloping roof panels being difficult to rotate.

[0009] According to some embodiments of the present invention, a sealing strip is provided on the side of the sloping roof panel near the horizontal roof panel, the sealing strip being used to abut against the side of the horizontal roof panel near the sloping roof panel.

[0010] According to some embodiments of the present invention, a temporary storage groove is formed on the top of the sealing strip.

[0011] According to some embodiments of the present invention, the inclined roof panel is provided with a mounting groove on the side near the horizontal roof panel, and the sealing strip passes through the mounting groove.

[0012] According to some embodiments of the present invention, the air duct is arranged side by side with the horizontal roof panel on the side near the inclined roof panel, and the air duct is provided with a plurality of air outlets, which are spaced apart along the length of the air duct.

[0013] According to some embodiments of the present invention, the exhaust pipe includes an exhaust pipe body passing through the exhaust hole and a branch pipe communicating with the exhaust pipe body. The top end of the exhaust pipe body is sealed, and the outlet of the branch pipe is arranged horizontally or downward.

[0014] According to some embodiments of the present invention, the outlet of the branch pipe is disposed toward the upper surface of the inclined roof panel.

[0015] According to some embodiments of the present invention, the exhaust assembly further includes a connecting pipe, the top end of which is connected to the branch pipe and the bottom end of which is connected to the air guide pipe.

[0016] According to some embodiments of the present invention, the roof structure further includes a drive mechanism disposed on the roof truss and drivenly connected to the inclined roof panel, the drive mechanism being used to drive the inclined roof panel to flip upward or downward.

[0017] According to a second aspect of the present invention, the steel structure factory building includes the roof structure described above.

[0018] The steel structure workshop according to embodiments of the present invention has at least the following beneficial effects:

[0019] After rain or snow, snow may accumulate on the sloping roof panels of the steel structure factory building of this invention. By controlling the rotation of the sloping roof panels, the tilt angle of the sloping roof panels can be increased, which facilitates the sliding of snow and reduces the risk of the sloping roof panels collapsing, thereby reducing the risk of the entire roof structure collapsing. In addition, during rain or snow, due to the low temperature, ice may form at the joint between the sloping roof panels and the horizontal roof panels, making it difficult to rotate the sloping roof panels. Before rotating the sloping roof panels, exhaust fans and heating elements can be turned on to blow hot air onto the joint between the sloping roof panels and the horizontal roof panels to thaw the ice and improve the problem of the sloping roof panels being difficult to rotate.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figure 1 , Figure 2 As shown, an embodiment of the present invention relates to a roof structure including a roof truss 100, a roof panel assembly 200, and an exhaust assembly 300.

[0035] The roof truss 100 is one of the components of a building, serving as a truss for the roof structure. Specifically, in this embodiment, the roof truss 100 is a steel roof truss 100.

[0036] The roof panel assembly 200 is disposed on the roof truss 100, and the roof panel assembly 200 includes a horizontal roof panel 210 and a sloping roof panel 220 disposed on the side of the horizontal roof panel 210.

[0037] Specifically, the horizontal roof panel 210 is mounted on the roof truss 100 and is horizontally positioned, while the inclined roof panel 220 is mounted on the roof truss 100 and is inclined, with the inclined roof panel 220 positioned to the side of the horizontal roof panel 210. The side of the inclined roof panel 220 furthest from the horizontal roof panel 210 is lower than the side of the inclined roof panel 220 closest to the horizontal roof panel 210; in other words, the inclined roof panel 220 gradually rises from its side furthest from the horizontal roof panel 210 to its side closest to the horizontal roof panel 210.

[0038] Furthermore, the side of the inclined roof panel 220 away from the horizontal roof panel 210 is rotatably connected to the roof truss 100, and the side of the inclined roof panel 220 near the horizontal roof panel 210 can be flipped upwards and connected to the side of the horizontal roof panel 210 near the inclined roof panel 220.

[0039] Specifically, the sloping roof panel 220 includes a sealed state. When the sloping roof panel 220 is in the sealed state, the side of the sloping roof panel 220 near the horizontal roof panel 210 is aligned with the side of the horizontal roof panel 210 near the sloping roof panel 220, and the side of the sloping roof panel 220 near the horizontal roof panel 210 is in a sealed fit with the side of the horizontal roof panel 210 near the sloping roof panel 220. The sloping roof panel 220 can be rotated in a controlled manner, thereby causing the side of the sloping roof panel 220 near the horizontal roof panel 210 to flip upward, thereby increasing the tilt angle of the sloping roof panel 220.

[0040] The inclined roof panel 220 is connected to the roof truss 100 via a pivot on the side away from the horizontal roof panel 210.

[0041] It should be noted that the rotation of the tilted roof panel 220 can be controlled manually or electrically.

[0042] In some embodiments, an operator can hold a support pole to lift the inclined roof panel 220, thereby causing the inclined roof panel 220 to rotate.

[0043] In other embodiments, a drive mechanism (not shown) is provided on the roof truss 100, which is drivenly connected to the inclined roof panel 220. The drive mechanism is used to drive the inclined roof panel 220 to flip upward or downward.

[0044] The drive mechanism can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. One end of the drive mechanism is hinged to the roof truss 100, and the other end is hinged to the inclined roof panel 220.

[0045] like Figure 3As shown, the horizontal roof panel 210 is provided with an exhaust hole, and the exhaust assembly 300 includes an exhaust pipe 310 passing through the exhaust hole, an exhaust fan (not shown) disposed in the exhaust pipe 310, and a heating element (not shown) disposed in the exhaust pipe 310.

[0046] Specifically, the exhaust vents are opened on the horizontal roof panel 210 and pass through the upper and lower sides of the horizontal roof panel 210. The exhaust pipe 310 is fixedly installed in the exhaust vents. The steel structure factory building using the above-mentioned roof structure can exchange airflow with the outside through the exhaust pipe 310.

[0047] It should be noted that the exhaust fan is configured to be able to be turned on or off. When the exhaust fan is turned on, it can accelerate the airflow inside the steel structure factory building that uses the roof structure to be discharged to the outside. The heating element is configured to be able to be turned on or off. When the heating element is turned on, it can heat the airflow, so that the airflow discharged to the outside is hot airflow.

[0048] It is understandable that the heating element is a heater, which can be placed on the side of the exhaust fan closer to the outside or on the side of the exhaust fan farther away from the outside.

[0049] Combination Figure 3 and Figure 4 Furthermore, the exhaust assembly 300 also includes an air guide duct 320 connected to the exhaust duct 310, with the air outlet of the air guide duct 320 facing the junction of the inclined roof panel 220 and the horizontal roof panel 210.

[0050] It is understandable that at least a portion of the airflow entering the exhaust duct 310 from the interior of the steel structure factory building with the aforementioned roof structure will enter the guide duct 320, and then be blown towards the junction of the sloping roof panel 220 and the horizontal roof panel 210 through the guide duct 320. When both the exhaust fan and the heating element are on, the airflow blown towards the junction of the sloping roof panel 220 and the horizontal roof panel 210 through the exhaust duct 310 is hot air.

[0051] It should be noted that after rain or snow, snow may accumulate on the sloping roof panels 220 of the steel structure factory building using the above-mentioned roof structure. By controlling the rotation of the sloping roof panels 220, the tilt angle of the sloping roof panels 220 can be increased, which facilitates the sliding of snow and reduces the risk of the sloping roof panels 220 collapsing, thereby reducing the risk of the entire roof structure collapsing. In addition, during rain or snow, due to the low temperature, ice may form at the joint between the sloping roof panels 220 and the horizontal roof panels 210, making it difficult to rotate the sloping roof panels 220. Before rotating the sloping roof panels 220, the exhaust fan and heating element can be turned on to blow hot air towards the joint between the sloping roof panels 220 and the horizontal roof panels 210 to thaw the ice and improve the problem of the sloping roof panels 220 being difficult to rotate.

[0052] like Figure 4 , Figure 5 As shown, in some embodiments, a sealing strip 222 is provided on the side of the sloping roof panel 220 near the horizontal roof panel 210, and the sealing strip 222 is used to abut against the side of the horizontal roof panel 210 near the sloping roof panel 220.

[0053] Understandably, when the sloping roof panel 220 is in a sealed state, the sealing strip 222 abuts against the side of the horizontal roof panel 210 near the sloping roof panel 220, and the sealing strip 222 plays a sealing role, which can prevent rainwater from falling into the steel structure factory building through the gap between the sloping roof panel 220 and the horizontal roof panel 210.

[0054] Furthermore, the inclined roof panel 220 has an installation groove 221 on the side near the horizontal roof panel 210, and the sealing strip 222 passes through the installation groove 221.

[0055] Specifically, a portion of the sealing strip 222 passes through the mounting groove 221, and a portion protrudes from the mounting groove 221. The portion of the sealing strip 222 protruding from the mounting groove 221 is used to abut against the side of the horizontal roof panel 210 that is close to the inclined roof panel 220.

[0056] Furthermore, the sealing strip 222 is detachably connected to the sloping roof panel 220, so that the sealing strip 222 can be replaced when it wears out.

[0057] like Figure 5 As shown, in some embodiments, a temporary storage groove 2223 is formed on the top of the sealing strip 222.

[0058] Understandably, when the exhaust fan and heating element are turned on, the hot airflow blows towards the joint between the sloping roof panel 220 and the horizontal roof panel 210 to achieve the purpose of thawing. The water that turns from the ice can then flow into the temporary storage tank 2223. In this way, after the sloping roof panel 220 is flipped, the risk of water dripping into the interior of the steel structure factory building can be reduced.

[0059] Specifically, the sealing strip 222 includes a first sealing part 2221 and a second sealing part 2222. The first sealing part 2221 is disposed on the side of the inclined roof panel 220 near the horizontal roof panel 210, and the first sealing part 2221 is in contact with the side of the inclined roof panel 220 near the horizontal roof panel 210. The second sealing part 2222 cooperates with the first sealing part 2221 to form a temporary storage groove 2223. The second sealing part 2222 is used to be in contact with the side of the horizontal roof panel 210 near the inclined roof panel 220. When the ice at the joint between the inclined roof panel 220 and the horizontal roof panel 210 melts into water, some of the water can flow into the temporary storage groove 2223. In this way, after the inclined roof panel 220 is flipped, the risk of water dripping into the interior of the steel structure factory building can be reduced.

[0060] Understandably, if the second sealing part 2222 is not provided to form a temporary storage groove 2223 at the top of the sealing strip 222, the water from the melting ice will accumulate in the pit between the sealing strip 222 and the horizontal roof panel 210. After the inclined roof panel 220 is flipped upwards, the water in the pit will fall into the steel structure factory building. However, by providing the second sealing part 2222 to form a temporary storage groove 2223 at the top of the sealing strip 222, when the ice at the joint between the inclined roof panel 220 and the horizontal roof panel 210 melts into water, some of the water can flow into the temporary storage groove 2223. In this way, after the inclined roof panel 220 is flipped, the risk of water dripping into the interior of the steel structure factory building can be reduced.

[0061] like Figure 3 , Figure 4 As shown, in some embodiments, the air duct 320 is arranged side by side with the horizontal roof panel 210 near the side of the inclined roof panel 220, and the air duct 320 is provided with multiple air outlets, which are spaced apart along the length of the air duct 320.

[0062] Understandably, the air duct 320 is positioned above the horizontal roof panel 210, and the air duct 320 and the horizontal roof panel 210 are arranged side by side with the horizontal roof panel 210 near the inclined roof panel 220. By arranging multiple air outlets at intervals along the length of the air duct 320, the hot air discharged through the air outlets can be blown to various positions at the joint between the inclined roof panel 220 and the horizontal roof panel 210, thereby facilitating the thawing of the joint between the inclined roof panel 220 and the horizontal roof panel 210.

[0063] like Figure 3 , Figure 4 As shown, in some embodiments, the exhaust pipe 310 includes an exhaust pipe body 311 passing through an exhaust hole and a branch pipe 312 communicating with the exhaust pipe body 311. The top of the exhaust pipe body 311 is sealed, and the outlet of the branch pipe 312 is set horizontally or downward.

[0064] Understandably, when the steel structure workshop is ventilated, the airflow can pass through the main body of the exhaust pipe 311 and the branch pipe 312 in sequence to the outside. The top of the main body of the exhaust pipe 311 is sealed, and the outlet of the branch pipe 312 is set horizontally or downwards, which can prevent rain and snow from entering the interior of the steel structure workshop through the exhaust pipe 310 during rainy or snowy weather.

[0065] Furthermore, the outlet of the branch pipe 312 is positioned towards the upper surface of the sloping roof panel 220. In this way, the airflow from the branch pipe 312 can also blow onto the snow on the sloping roof panel 220, achieving the purpose of thawing or blowing the snow off the sloping roof panel 220, thereby reducing the risk of the sloping roof panel 220 collapsing.

[0066] Furthermore, the exhaust assembly 300 also includes a connecting pipe 330, the top end of which is connected to the branch pipe 312, and the bottom end of which is connected to the air guide pipe 320.

[0067] The present invention also relates to a steel structure factory building, including the roof structure described above.

[0068] After rain or snow, snow may accumulate on the sloping roof panel 220 of the steel structure factory building of this invention. By controlling the rotation of the sloping roof panel 220, the tilt angle of the sloping roof panel 220 can be increased, which facilitates the sliding of snow and reduces the risk of the sloping roof panel 220 being crushed, thereby reducing the risk of the entire roof structure being crushed. In addition, during rain or snow, due to the low temperature, ice may form at the joint between the sloping roof panel 220 and the horizontal roof panel 210, making it difficult to rotate the sloping roof panel 220. Before rotating the sloping roof panel 220, the exhaust fan and heating element can be turned on to blow hot air towards the joint between the sloping roof panel 220 and the horizontal roof panel 210 to thaw the ice and improve the problem of the sloping roof panel 220 being difficult to rotate.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0070] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
