The membrane area of Hebei Cangzhou ice rink air dome is 2800 square meters, and the completion speed is very fast. It only took 45 days to complete.

It has the ability to undertake individual events above the national level and can meet the needs of public fitness.

Its appearance looks like a tent, soft and powerful, but inside it is unique. According to the introduction of the previous article, we know that the air film building is a building structure system that supports the main body of the building by the pressure difference between inside and outside. With its increasing popularity, the many advantages of air film venues have gradually become known to people.

It has the following characteristics:

1. Low construction cost. Compared with traditional stadiums, the construction cost of air film stadiums has been reduced by 50%-70%.

2. Easy to maintain and use. Air-film buildings only need an uninterrupted power supply to maintain air pressure.

3. Short construction period. Generally, it takes about 4 to 6 months from construction to completion of air film stadiums, which is much shorter than the construction time of traditional stadiums.

4. Flexible disassembly and assembly. The modular building model enables the prefabricated stadiums to be replicated and relocated. The use rate of repeated relocation is as high as 50%-90%, but the service life is as long as 20 to 30 years.

5. Isolate the haze. In winter, especially in the severe season of haze, the completely airtight air-film building combined with the air purification system can effectively isolate PM2.5.
