An air-supported sports hall is a fully enclosed facility whose exterior is constructed using high-strength, highly flexible membrane materials—commonly classified as tensile membranes or structure membranes—that form a key part of modern fabric structure systems. This building is entirely supported by air; it utilizes the differential between internal and external air pressures to create a unique pneumatically stressed membrane system, maintaining overall stability without any traditional external supports. In some designs, prestressed membranes techniques are applied to pre-tension the membrane prior to installation, further enhancing wind resistance and safety.
The structure is secured to the ground using specialized anchoring methods, and advanced intelligent control systems are employed to regulate interior air pressure, resulting in a column-free space. This design not only ensures that the air-supported sports hall can effectively withstand natural hazards such as wind, sand, rain, snow, and fire, but also makes the installation and dismantling processes simple and flexible.
Moreover, without beams or columns interrupting the interior, space utilization is maximized, making the facility ideal for hosting large-scale sporting events, exhibitions, and various other activities. Combined with an air-cushioned insulation system and membranes with high light transmittance and low thermal absorption (typically referred to as structure membranes), the building is highly energy-efficient and environmentally friendly. With low construction costs, fast build times, and short construction cycles, it is an excellent choice for schools, medium-to-large enterprises, and other permanent sports venues.
In summary, an air-supported sports hall—constructed with tensile membranes, structure membranes, prestressed membranes, and pneumatically stressed membranes as part of a modern fabric structure—offers outstanding safety, flexibility, and aesthetic appeal while adhering to green, energy-saving design principles. Its innovative design and sustainable features provide extensive potential for a wide range of applications.
