What is a Large-span Steel Structure Airport Terminal?
A large-span steel structure airport terminal is a core public transportation building that uses high-strength steel as the main load-bearing structure, with a span of more than 30 meters (the steel structure standard defines a span of more than 60 meters as a large-span structure). It integrates advanced steel structure design, modular prefabrication and intelligent construction technology, and the main components such as roof grid, steel frame, support column and curtain wall are prefabricated in the factory, then transported to the construction site for hoisting and assembly. As the core hub of airport operation, it undertakes the functions of passenger check-in, security inspection, waiting, boarding, luggage handling and logistics services, and can accommodate thousands to tens of thousands of passengers per hour. With the characteristics of large space, light weight, high strength, beautiful appearance and efficient construction, it has become the mainstream choice of modern airport terminal construction around the world, and is an important symbol of a city's internationalization level and transportation hub capacity. Our large-span steel structure airport terminals fully comply with international standards such as CE, ASTM, ISO, and can be customized according to the air traffic volume, geographical environment and local building codes of different countries and regions.
Product Characteristics
Super Large Span & Unobstructed Space
The span can reach 30-300 meters, and the roof adopts spatial structure forms such as grid structure, truss structure and cable dome structure, which can realize a large-area column-free space. It can flexibly layout check-in areas, security inspection channels, waiting halls and boarding gates, ensuring smooth passenger flow and unobstructed space, and fully meeting the functional needs of large passenger flow and efficient operation of the airport. The maximum span of some large-scale terminal roof structures can even reach more than 270 meters, realizing a seamless and open space experience.
Light Weight & High Structural Strength
The main structure is made of high-quality high-strength steel (Q355B, ASTM A36, etc.), which has excellent tensile and compressive strength. The weight of the steel structure is only 1/3-1/5 of that of the traditional reinforced concrete structure, which can effectively reduce the load of the foundation project, save the cost of foundation construction, and adapt to the complex geological conditions of airport construction sites. At the same time, it has strong wind resistance, seismic resistance and snow load resistance, and can adapt to various harsh natural environments such as coastal typhoons, plateau cold and earthquake-prone areas.
Flexible and Beautiful Appearance & Cultural Integration
The steel structure has strong plasticity, and can be designed into various shapes such as curved surface, streamline and special shape according to the urban cultural characteristics and architectural aesthetics, such as the "flying fish" shape and the shape simulating mountain ranges, which can not only meet the functional needs, but also become a landmark building of the city and the airport. The roof can be equipped with light-transmitting membrane materials or glass curtain walls to achieve good lighting effects, reduce energy consumption, and integrate the regional cultural connotation into the architectural design, showing the unique charm of the region.
High Prefabrication Degree & Efficient Construction
The main components (steel grid, steel columns, curtain walls, etc.) are prefabricated in the factory with standardized production, which ensures the precision and quality of the components. The on-site construction only needs hoisting and assembly, and advanced technologies such as hydraulic synchronous lifting and BIM digital pre-assembly are adopted to greatly reduce on-site wet work, shorten the construction period, and the construction efficiency is 50%-70% higher than that of traditional concrete terminals. It can realize rapid delivery and put into use earlier, reducing the impact on airport normal operation.
Green Environmental Protection & Energy Saving
Steel materials can be 100% recycled and reused, which conforms to the global low-carbon and environmental protection development trend. No a large amount of construction waste is generated during the construction process, which reduces environmental pollution. At the same time, the building adopts energy-saving design, such as light-transmitting roof, natural ventilation system, rainwater collection system and solar energy utilization, which can effectively reduce the later operation energy consumption. Some projects even use carbon fiber cables to further reduce energy consumption and realize green and sustainable development .
Intelligent & Multi-functional Integration
It can be integrated with intelligent airport systems, such as intelligent check-in, security inspection, luggage sorting, passenger flow monitoring and intelligent operation and maintenance systems, to improve the efficiency of airport operation and passenger travel experience. The internal space can be flexibly divided, which can not only meet the basic functions of passenger transportation, but also set up commercial areas, catering areas, VIP lounges and other supporting spaces to realize multi-functional integration and improve the comprehensive utilization rate of the space.
Product Advantages
Superior Safety Performance
Strictly in accordance with international building codes, aviation industry standards and seismic standards, the seismic grade can reach 8-9 degrees, and the wind resistance grade can reach 12 levels. It can effectively resist natural disasters such as earthquakes, strong winds, heavy snow and typhoons. The structure is stable and reliable, and the service life can reach 50-100 years. The fire rating reaches Grade A1, equipped with advanced fire protection systems (intelligent fire detection, fire-fighting robot, fire-fighting sprinkler system), which can effectively ensure the safety of passengers, staff and the terminal during use.
Cost-effective & Low Comprehensive Cost
Although the initial investment of steel structure is slightly higher, the prefabricated production reduces the on-site labor cost and construction period cost. The steel structure has low later maintenance cost, long service life and high recyclability, which can effectively reduce the comprehensive cost of the project. At the same time, the optimized structural design and new material application (such as carbon fiber cable) can reduce the steel consumption by 10%-15%, further saving the cost of materials.
Strong Customization & Wide Adaptability
We can customize the span, area, passenger flow capacity, appearance shape, interior layout and supporting facilities according to the customer's needs, airport scale, regional climate, geological conditions and local building standards.
