Air-film building refers to a kind of building structure system that uses building membrane material as the shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-film building, supporting the main body of the building.

working principle

Working principle of air film A complete air film building system also includes lighting system and access control system.

1. The air film supports the whole building by the pressure difference between inside and outside. Because of the flexibility of materials and the inherent effectiveness of the structure and the arc-shaped shape, there are no members under bending, torsion and compression;

2. No frame or beam column support is required inside, and the span can reach 110 meters;

3. It can be seen from the figure below that with the increase of atmospheric pressure, the environmental oxygen content is increasing, so the pressure difference inside and outside the gas film will not have any adverse impact on the human body, but will help people to engage in sports or physical work; Generally, the pressure difference between inside and outside is 250Pa, about 0.0025 atmospheres (equivalent to the pressure difference between the first and ninth floors of normal buildings)
