Description

Technical Field

[0001] This invention belongs to the field of steel structure technology and relates to a louver, particularly a roof louver suitable for typhoon areas. Background Technology

[0002] Currently, most industrial plants, warehouses, and airport terminals are constructed using steel frame structures. For ventilation and heat dissipation, ventilation louvers are typically installed on the roofs. However, existing ventilation louvers have fixed ventilation mechanisms, meaning their vents are always open. This makes it impossible to control their opening and closing or adjust the size of the vents, resulting in poor ventilation and heat dissipation, especially in winter or during inclement weather such as rain or typhoons. The inability to close the vents allows cold air or rainwater to enter, potentially causing a drop in factory temperature or damage to equipment, raw materials, or finished products, leading to significant losses.

[0003] For example, a steel structure factory roof ridge ventilation duct disclosed in Chinese patent literature (application number: 201711488933.X) includes steel beams, a first support plate, a second support plate, a cover plate, a first drive mechanism, a second drive mechanism, multiple first support beams, multiple second support beams, a first duct frame, a second duct frame, and a gable-shaped top frame. This invention provides a first ventilation opening and a second ventilation opening on the cover plate, and provides a first windbreak plate and a second windbreak plate to close the first and second ventilation openings respectively. However, this ventilation duct has a small span, poor ventilation, and low strength, making it unsuitable for use on steel frame structures in typhoon-prone areas. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems with existing technologies by proposing a roof louver that is suitable for typhoon-prone areas, has a wider span, better ventilation, and stronger strength.

[0005] The objective of this invention can be achieved through the following technical solution: A roof ventilator suitable for typhoon-prone areas. This roof ventilator is installed above the ventilation opening on the roof. The roof ventilator includes a symmetrical truss, which includes two rows of parallel columns fixed to the roof. A top frame is fixed to the upper end of each column, and a top plate is fixed to the upper end of each top frame. The ventilator is characterized by having ventilator frames fixed to both sides of the top frame, with ventilation openings formed at the inner ends of the two ventilator frames, and a water outlet formed at the lower end of each ventilator frame and the roof. A vertically arranged support column is provided between the ventilator frame and the corresponding top frame. A second support column is provided between the lower side of the ventilator frame and the corresponding column, with both ends of the second support column fixed to the corresponding column and the inner middle of the corresponding ventilator frame. The upper end of the ventilator frame is arc-shaped, and a color steel panel is fixed to the outer wall of the ventilator frame. The color steel panel is arranged along the edge of the ventilator frame, and the upper end of the ventilator frame is located inside the outer end of the top plate.

[0006] This roof ventilator comprises symmetrical trusses constructed from welded square tubing, effectively increasing its width and providing advantages such as wider span and better typhoon resistance. Ventilation openings are formed at the inner ends of the two ventilator frames. Indoor air is ventilated through these openings, while rainwater falls from the openings onto the roof slab and is discharged through outlets, offering excellent ventilation and drainage.

[0007] In the aforementioned roof louver suitable for typhoon-prone areas, a diagonal support rod is provided between the column and the roof frame, with both ends of the diagonal support rod welded and fixedly connected to the column and the roof frame, respectively. This design improves the connection strength between the column and the roof frame, thus enhancing typhoon resistance.

[0008] In the aforementioned type of roof louver suitable for typhoon-prone areas, the top panel is a skylight panel. Using a skylight panel for the top panel has the advantage of good lighting performance.

[0009] In the aforementioned roof louver suitable for typhoon-prone areas, louvers are installed between adjacent support columns, and the louvers are fixed to the outside of the support columns. By installing these louvers, the wind and rain in typhoon-prone areas can be effectively filtered without affecting air convection, providing secondary rain protection against typhoon rain.

[0010] In the aforementioned roof louver suitable for typhoon-prone areas, the cross-section of the color steel panel is serrated. The serrated cross-section of the color steel panel provides the advantage of high strength.

[0011] In the aforementioned rooftop louver suitable for typhoon-prone areas, a sealing plate is provided on the roof. One end of the sealing plate is hinged to the roof. A cylinder is provided on the roof to drive the sealing plate to rotate, and the cylinder body is hinged to the roof. The piston rod of the cylinder is hinged to the other end of the sealing plate. The cylinder can push the sealing plate to block the water outlet. By using the cylinder to drive the sealing plate to rotate and block the water outlet, the typhoon resistance is improved.

[0012] In the aforementioned roof louver suitable for typhoon-prone areas, a sealing plate two is provided on the upper side of the roof panel, and a cylinder two is provided on the roof frame. The cylinder two pushes the sealing plate two upward to block the vent. By having the cylinder two drive the sealing plate two upward to block the vent, the roof louver can be sealed, thus improving its typhoon resistance.

[0013] In the aforementioned roof louver suitable for typhoon-prone areas, a second cylinder is provided in the middle of the top frame, and the piston rod of the second cylinder is fixedly connected to the middle of the second sealing plate. The second cylinder in the middle of the top frame provides better support for the middle of the second sealing plate, thereby improving the strength of the roof louver.

[0014] In the aforementioned roof ventilator suitable for typhoon-prone areas, the cylinders are arranged in two rows on the left and right sides, respectively, and the two rows of cylinders are fixedly connected to both sides of the sealing plate. This arrangement allows the sealing plate to firmly seal the vent, providing good support and improving typhoon resistance.

[0015] In the aforementioned rooftop louver suitable for typhoon-prone areas, cylinders one and two are replaced by hydraulic cylinders. Replacing cylinders one and two with hydraulic cylinders results in greater force, improving the strength of the rooftop louver and providing better typhoon resistance.

[0016] In the aforementioned rooftop louver suitable for typhoon-prone areas, a louver bracket is fixedly connected to the lower end of the supporting column, and the louver bracket is fixedly connected to the roof. The louver bracket is made of I-beams, which has the advantages of high strength and good support effect.

[0017] Compared with existing technologies, this roof ventilator suitable for typhoon-prone areas has the following advantages: 1. This roof ventilator includes symmetrical trusses, which are welded from square tubes. This effectively increases the width of the roof ventilator and has the advantages of a wider span and better typhoon resistance. 2. The inner ends of the two air vents form ventilation openings. The indoor air is ventilated and exchanged through the ventilation openings and air vents. Rainwater falls from the ventilation openings to the top plate and flows out through the drain outlet, which has the advantages of good ventilation and drainage. 3. The two ends of the diagonal support rod are welded and fixed to the column and the top frame respectively, which has high connection strength and improves the typhoon resistance effect; 4. The cross-section of the color steel panel is serrated, which has the advantage of high strength. Attached Figure Description
