Ridge ventilator is mainly use the aerodynamic wind carrier theory of "wind acting on objects, the windward side is pressure, the leeward side and the side in the downwind direction to expand for suction, then, the editor of Mcwell will explain the rain and snow protection design of the roof ridge vent.

1. The type of ridge ventilator on the roof affects the design of rain and snow protection

Because of the different types of roof smoke vent, the required rain and snow protection designs are different. For example, the streamlined natural ventilator has a circular arc design, which has good rain and snow resistance and is not easy to form a rain and snow accumulation; and the overall design of the font-shaped roof natural ventilator is "one", which is easy to form a rain and snow accumulation and is not suitable for installation in snowy areas.

2. The profile of the roof ridge vent of the factory building affects the design of rain and snow protection

Generally speaking, the wind and snow load of the roof ventilator of the factory building mainly depends on the design of the steel structure, the thickness of the profile and the thickness of the weatherproof plate. The specifications of the steel structure of the ventilator are very important. The first guarantee is to meet the wind and snow load of the workshop to ensure that the ventilator can operate normally under any extreme conditions.

3. Requirements for the installation of roof smoke vent

Steel structure roof smoke vent can achieve ventilation, lighting and smoke exhaust in the workshop. In order to avoid excessive loads, it is necessary to avoid using excessively large profiles. Among them, the standardized installation of the ventilator's outer guard plate, rain plate, and flooding plate is also an important guarantee to ensure the rain and snow resistance of the ventilator, and the installation is carried out in strict accordance with the drawings.
