2. Main Structural Components of Air-supported Structures
2.1 Membrane Materials
The primary materials used are PVC-based composites. Qi Li Fang typically uses PVDF membrane for its superior durability.
| Material Type | Composition & Features | Lifespan & Performance |
|---|---|---|
| PVC Membrane | Polyester fiber fabric + PVC (Polyvinyl Chloride) coating. Often treated with Acrylic resin for anti-dirt properties. | Lower performance. Prone to discoloration, staining, and deterioration over time. Shorter service life compared to PVDF. |
| PVDF Membrane | PVC membrane with an additional PVDF (Polyvinylidene Fluoride) resin coating applied to the surface. | Enhanced durability. Service life improved to approximately 10-20 years. Offers better weather resistance and self-cleaning properties. |
| Structural Longevity | While specific codes for air-structure lifespan are not detailed in current domestic regulations, the structural design follows a 50-year load statistical cycle. With proper maintenance, the building structure can last up to 30 years. |
2.2 Foundation & Base System
- Foundation: The load-bearing base layer in contact with the ground. Designs consider bearing capacity, stability, and drainage. Options include Shallow Foundations (spread footings, raft foundations) and Deep Foundations (pile foundations).
- Ground Treatment Layer: Includes cushion layers and geological treatments to ensure uniform support and anti-settlement capacity.
- Base Frame: Steel structure used to fix and support the inflatable building components. Must have sufficient strength to withstand loads.
- Fixing Methods: Utilizes ground anchors, ground nails, or anchor bolts to securely fasten the membrane edges to the base structure.
2.3 Fresh Air & Ventilation System
- Natural Ventilation: Utilizes airflow differences through openings on sides or the top.
- Mechanical Ventilation (Fresh Air System):
- Fans: Provide airflow and maintain internal air pressure (via air pumps, airbags, pipes, and valves) to keep the membrane inflated.
- Filters: Remove particulates and pollutants from incoming air.
- Climate Control: Devices to regulate humidity and temperature.
- Ducts & Vents: Distribute air flow.
- Exhaust System: Includes exhaust fans and ducts to remove stale air and odors.
- Auxiliary Equipment: Additional fans for stronger airflow if required.
- Automatic Control: Sensors monitor CO2, temperature, and humidity to automate the system.
2.4 HVAC Systems (Heating, Ventilation, and Air Conditioning)
Flexible configuration based on needs and building size:
- Central Air Conditioning: For large areas.
- Split Units: For smaller or specific zones.
- Heating Options: Boilers or geothermal heating (common in Northern regions).
2.5 Backup Power System
- A matching diesel generator set is标配 (standard配备) to ensure 24/7 operation. It automatically starts in case of a power outage or during maintenance.
2.6 Airlock Entry System
- Personnel Entry: Rotation doors or Airlock doors.
- Equipment Entry: Airlock doors (double-layer doors with a pressure balance chamber and automatic electromagnetic closure to prevent air leakage).
- Emergency Exits: 1-3 emergency evacuation doors are installed.
2.7 Lighting System
- Ceiling Lighting: Recessed or suspended LED/fluorescent lights for uniform illumination.
- Wall Washing: Lights mounted on walls for ambient effects.
- Floor/Ground Lighting: For landscape/path guidance.
- Light Strips: Flexible LED strips for indirect lighting on curves.
- Emergency Lighting: Essential for power failures.
2.8 Intelligent Control System
An integrated system that manages ventilation, HVAC, generators, and environmental monitoring. It allows for unattended operation and remote control via PC, adjusting fan speeds and temperatures based on internal and external conditions (wind speed, etc.).
3. Key Features & Advantages
- Durable Materials: High-strength composite materials with high reflectivity (SR) and emissivity (IE). Features flame retardancy, self-cleaning, and waterproofing.
- Aesthetic Freedom: Flexible membrane allows for diverse, novel, and iconic architectural forms with rich color options.
- Economic Efficiency: The roof weight is only 1/30th of a conventional steel roof, reducing costs for walls and foundations. Offers high commercial visibility.
- Rapid Construction: All fabrication is done in the factory; on-site work is purely installation. Construction speed is nearly double that of traditional buildings.
- Energy Conservation: High solar reflectivity and low thermal conductivity minimize heat gain. The semi-transparency allows for natural diffused lighting, reducing electricity costs.
- Large Span Capability: Due to its light weight, it can span large areas without internal support columns, allowing for flexible space utilization.
