Description

A kind of rainproof and ventilation louver suitable for high-rise buildings

technical field

The utility model relates to the construction field, in particular to a rainproof and ventilated louver suitable for high-rise buildings.

Background technique

Shutters are a style of windows that originated in China. Shutters can be used not only as a decoration, but also as a ventilation and light transmission, which are often used in modern buildings. With the development of society, high-rise buildings are increasing day by day, and their height is also increasing day by day. When designing high-rise buildings, special consideration should be given to safety issues under strong wind and rain. Therefore, the structural design of high-rise buildings is usually closely related to wind loads. The strength of wind loads depends not only on natural characteristics, but also on the height and shape of buildings. At present, the shape and structure of high-rise buildings will be designed with a small shape factor, so as to reduce the destructive influence of wind load on high-rise buildings. At the same time, when the arc-shaped or broken-line plane of a high-rise building is concave to the wind, there will be a large transverse wind force and resonance to cause the fluid vortex to fall off the structure. Designers will use the building body to vent the wind, that is, set vent openings at a reasonable height of the building body, or replace it with high-performance rainproof and ventilated louvers.

The shutters currently on the market have a simple blade structure and a single installation form of the blades, which cannot meet the situation of high-rise buildings running into strong wind and rain. On the other hand, since the blades of the existing shutters are usually fixed on the side frame by self-tapping screws, they will loosen or fall off under the influence of strong wind load for a long time, which will cause the shutters to leak and the shutters to fall off. the result of.

Therefore, the applicant is committed to providing a rainproof ventilation louver suitable for high-rise buildings, which has good ventilation and air permeability, and the design and installation form of the louvers are reasonable and stable, and can effectively reduce the Wind pressure, and can well block the rain.
