Is the ice ribbon newly built?

The ice ribbon is newly built. The Ice Ribbon of the National Speed Skating Pavilion is the only newly-built ice competition venue for the Beijing 222 Winter Olympics. Once it came out, it attracted a lot of attention.

The only newly-built competition venue in Beijing for the p>222 Winter Olympics is the National Speed Skating Hall. The National Speed Skating Hall, also known as the Ice Ribbon, is the landmark venue of the main competition area of the 222 Winter Olympics. Its total area is about 12, square meters, which can accommodate 12, tourists. It is very spectacular.

Introduction of Ice Ribbon

The ice ribbon of National Speed Skating Hall adopts the world's largest single-layer bidirectional orthogonal saddle-shaped cable net roof, and the steel consumption is only a quarter of that of the traditional roof.

The National Speed Skating Gymnasium is the world's first Winter Olympic Speed Skating Gymnasium adopting the technology of transcritical direct cooling of carbon dioxide. This technology is an advanced and environmentally friendly ice-making technology in the world, with carbon emission value approaching zero and ice-making energy efficiency greatly improved.

after the games, the ice surface can be refrigerated in different zones, and the temperature of each ice can be controlled separately, so that the venues can be operated at the same time and used differently. Two key design schemes, the integrated design of ice-making system and the structural design of ice plate, have been patented.

In order to build the fastest ice, the National Speed Skating Hall strives for perfection in ice slab construction, and it takes more than 6 days to complete 8574 welds of ice-making steel pipes. The horizontal height difference of the concrete ice slab is about 4 mm, which is very smooth, and the temperature difference of the ice surface is controlled within .5 degrees Celsius, which is beneficial for athletes to create good results.
