China and Germany have completed 36 major sports stadiums, exhibition halls, structural design and construction of the museum film! Air-supported membrane structures (cable and membrane structures) are inflated to the building through a pressure control system that allows indoor maintain a certain pressure difference, the covering membrane by the buoyancy, and have some pre-tensile stress in order to ensure the system stiffness. Indoor Air Set automatic control system to adjust the indoor and outdoor air pressure in a timely manner, in order to adapt to changes in the external load. Because span without any support, therefore suitable for large-span buildings, generally used for large gymnasium. Inflatable membrane structure is inflated to a single film member to maintain adequate internal pressure, a plurality of film members may be combined to form a shape of a whole system by force, such a configuration of the membrane itself tightness requirements high, or the need to keep the inner membrane component inflated. The most typical inflatable membrane structure is water cube, inflatable membrane structures within the facade Water Cube total by 3065 air pillow composition, the maximum reached 70 square meters, covering an area of ??100,000 square meters, expand the area of ??260,000 square meters , is the world's largest inflatable membrane structural engineering, is the only fully-film structure for large public buildings completely closed. www.zdmjg.com www.szjrt.com.cn www.szjrt1.com
