Xi'an rooftop air-supported dome: where sporting spaces grow upwardsIn cities woven from steel and concrete, land resources grow ever scarcer. As ground-level space nears saturation, might sports facilities seek possibilities aloft? The answer lies in Xinyuan Air-Supported Structures' new rooftop air-supported dome project in Xi'an's Weiyang District—defying spatial constraints, two air-supported domes stand side by side atop the building with graceful lightness, infusing the city with fresh sporting vitality and leisure inspiration.Safety and comfort are the core considerations for Beijing Xinyuan Yijia Membrane Structure Technology Co., Ltd. in constructing rooftop air-supported membrane structures.From a structural standpoint, air-supported domes are inherently suited to rooftop installations. Comprising high-strength membrane material and air-supported structures, the main body weighs merely 3-5kg/m², significantly lighter than traditional steel or concrete venues. This eliminates the need for extensive rooftop reinforcement, requiring only minor localised anchoring points to mitigate load risks.At the construction level, air-supported structures employ a factory-prefabricated and on-site assembled model, eliminating the need for heavy lifting equipment or concrete pouring. The construction process comprises membrane installation, cable securing, equipment commissioning, and anchor point construction. The entire procedure is vibration-free and dust-free, causing no damage to the existing roof waterproofing, insulation layers, or parapet walls. Upon completion, the structure can be rapidly put into service without disrupting the normal operations of the main building.In terms of spatial utilisation, Xinyuan air-supported structures can be customised to match the dimensions of rooftop sites, accommodating both rectangular and irregularly shaped areas. Moreover, as a self-supporting, enclosed structure without internal columns, the air-supported membrane creates an unobstructed interior space, enabling the full utilisation of unused vertical space on rooftops.In terms of functionality, rooftop air-supported membrane tennis courts deliver an experience identical to ground-level venues, with certain features offering distinct advantages. For natural lighting, the Xinyuan membrane design team incorporates translucent membrane materials in specific areas to ensure even diffusion of daylight, eliminating shadows and glare within the facility. Complemented by anti-glare LED reflector lights specifically engineered for membrane structures, seamless supplementary lighting is provided during night-time or overcast conditions, enabling all-weather usability. Regarding temperature and humidity control, the air-supported structure's sealed design, combined with an integrated air handling system, maintains constant indoor climate conditions throughout the year.When rooftop spaces are revitalised, inflatable domes become bridges connecting urban dwellers with sporting pursuits. Under the dual carbon goals, rooftop inflatable domes emerge as an ideal choice for urban renewal, offering high space utilisation, low energy consumption and recyclability.
