Description

Technical Field

[0001] The utility model belongs to the technical field of building materials, and in particular relates to a middle rainproof lifting valve plate used in a factory building. Background Art

[0002] The factory roof ventilator, also known as the roof natural ventilator or roof natural ventilator, is a ventilation equipment installed on the roof of a steel structure factory building. It mainly has the functions of ventilation, lighting and smoke exhaust.

[0003] At present, the commonly used structure consists of a bracket, a rain shield and a gutter. The rain shield is an inverted V-shaped rain shield or an umbrella-shaped rain shield. Although these two designs can theoretically guide water to drain downward along the slope, in actual use, due to the influence of various factors such as wind direction and rain intensity, rainwater may not be able to be completely discharged along the predetermined path, resulting in poor drainage efficiency. Especially in strong winds or heavy rain, the inverted V-shaped rain shield may not be able to effectively cope with the discharge of a large amount of accumulated water; the umbrella-shaped design makes the rain shield relatively complex in structure and requires more support and fixing points. If it is improperly installed or the material selection is inappropriate, it may lead to a decrease in structural stability and increase safety risks. In addition, due to the umbrella-shaped design, the roof surface presents a certain curvature, which increases the sensitivity to wind to a certain extent. In strong winds, the umbrella-shaped rain shield may bear greater wind loads, increasing the risk of damage to the roof structure.

[0004] In order to be suitable for strong wind and rainstorm weather, some of them adopt multi-layer staggered rain shields, which have complex structures, high operating costs, and are difficult to repair and maintain. Summary of the invention

[0005] The utility model aims to provide a rainproof lifting valve plate for the middle part of a factory building, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a middle rain shield lifting valve plate for a factory building, comprising an upper rain shield, a middle rain shield, a guide plate and an inclined plate, wherein inclined plates extend downward at the edge positions on both sides of the upper rain shield, the middle rain shield is connected to the lower end of the inclined plate, the lower end of the middle rain shield is connected to the guide plate, the upper rain shield is a horizontally arranged horizontal plate, the angle between the upper rain shield and the inclined plate is: 130-°140°, the angle between the inclined plate and the middle rain shield is 135°-145°, the lower part of the guide plate extends into the guide groove of the ventilator, the connection of the inclined plates can make the overall structure more streamlined and reduce the resistance of the factory building in the wind. This design can reduce the impact of wind on the factory building when encountering strong winds, and improve the stability and safety of the factory building.

[0007] Preferably, the angle between the middle rain shield and the guide plate is 150°. This design can more effectively guide the airflow, reduce wind resistance, and enable the factory building to remain stable even in severe weather conditions.

[0008] Preferably, the upper rain shield, the middle rain shield, the guide plate and the inclined plate are integrally formed, thereby eliminating potential water leakage hazards, greatly simplifying the installation process and improving installation efficiency.

[0009] Technical effects and advantages of the utility model:

[0010] 1. This structure has good load capacity, ventilation and drainage effects, can save a lot of basic materials, simplify the manufacturing and installation of the product, and make it a product that is easy to standardize and popularize.

[0011] 2. This structure can reduce the angle of rainwater entry, thereby greatly enhancing the wind and rain protection effect, and can prevent external airflow backflow and rainwater leakage, solving the problem that the natural ventilation device on the roof of the building needs to be turned on for ventilation but is worried about the weather changes causing rain, snow, sand and dust to flow back with the wind.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1The utility model shows a specific embodiment of a middle rain shield lifting valve plate for a factory building: it includes an upper rain shield plate 1, a middle rain shield plate 2, a guide plate 3 and an inclined plate 4 which are integrally formed. The inclined plates 4 extend downwardly from the edges of both sides of the upper rain shield plate 1. The lower end of the inclined plates 4 is connected to the middle rain shield plate 2. The lower end of the middle rain shield plate 2 is connected to the guide plate 3. The upper rain shield plate 1 is a horizontally arranged horizontal plate. The angle between the upper rain shield plate 1 and the inclined plate 4 is 135°, the angle between the inclined plate 4 and the middle rain shield plate 2 is 140°, and the lower part of the guide plate 3 extends into the guide groove of the ventilator. The connection of the inclined plate 4 can make the overall structure more streamlined, increase the overall strength of the structure, and reduce the resistance of the factory building in the wind. This design can reduce the impact of the wind on the factory building when encountering strong winds, and improve the stability and safety of the factory building. In addition, the existence of the inclined plate 4 can effectively promote air convection and reduce the heat accumulation inside the factory building. The angle between the middle rain shield 2 and the guide plate 3 is 150°. This design can more effectively guide the airflow, reduce wind resistance, and keep the factory building stable under severe weather conditions. This angle design not only takes into account functional requirements, but also takes into account the stability of the structure. A reasonable angle allows the rain shield and the guide plate to be better fixed on the factory building structure, making it easier to guide rainwater away and reducing looseness or damage caused by wind or other external forces.

[0016] The material is PC endurance board with a thickness of 2mm and a light transmittance of 60%-90%. The lifting valve plate is light in weight, which can reduce the wear of the lifting mechanism during operation and extend the service life of the equipment. In addition, due to the light weight of this material, it is easy to carry on the roof, which reduces labor intensity and improves installation efficiency.
