Air Dome, featuring a unique architectural form and efficient space utilization, is becoming a popular option for various sports events, commercial activities and public facilities. Among the core technologies of air domes, the anchoring system acts as an anchor to ensure safe and stable operation. I. Core Components: Four Parts Form the Safety Barrier
Reinforced concrete ring beam: An annular load-bearing structure. Combined with steel mesh and concrete, it distributes loads evenly and serves as the basic framework of the anchoring system.
Embedded anchor bolts: Made of high-strength steel. Welded to the ring beam and deeply buried, they connect the membrane fabric to the foundation with strong tensile resistance, acting as key nodes for force transmission.
Waterproof rubber gasket: Elastic material that buffers stress between the membrane and foundation, and forms a sealing barrier to prevent leakage and air pressure loss.
Membrane clamping angle steel: Hot-dip galvanized. It compresses the membrane, gaskets and ring beam via nuts. The anti-slip design ensures no displacement under harsh conditions.
II. Working Principle: Dual Protection for Dynamic Balance
External loads are transmitted step by step along the path of "membrane fabric → angle steel → anchor bolt → ring beam → foundation" to avoid overload at a single point. Meanwhile, mechanical anchoring force forms a dynamic balance with internal air pressure to resist fluctuations of positive and negative wind pressure and maintain the stable shape of the air dome.
III. Core Advantages: Stability and High Efficiency
Resistance to harsh weather: Capable of withstanding Category 12 typhoons and 500mm snow cover, adapting to climatic requirements of different regions.
Long service life and low maintenance: Anti-corrosion treatment for anchor bolts and anti-aging design of gaskets deliver a service life over 15 years. Daily maintenance only requires checking nut tightness.
Green and efficient construction: Modular components shorten the construction period by 40%, reduce construction waste and allow reuse of temporary venues.
IV. Future Trends: Intelligent and Lightweight Upgrade
Integrated sensors monitor stress in real time and give early warnings of abnormalities;
Carbon fiber anchor bolts and nano-coated gaskets are applied to reduce weight while improving corrosion resistance;
Prefabricated components enable rapid industrial assembly.
Though hidden in the foundation, the anchoring system supports the safety and durability of air dome buildings with sophisticated design. Choosing reliable anchoring builds long-term protection for air domes.
