What does the National Speed Skating Hall use?

The National Speed Skating Gymnasium is designed with hyperbolic saddle-shaped single-layer cable net roof, which is the largest single-layer bidirectional orthogonal saddle-shaped cable net roof gymnasium in the world. This structural design can greatly save materials, and the steel consumption is only a quarter of that of the traditional roof.

The construction team of the sliding pavilion called this cable net a canopy. The process of weaving the canopy can be simply understood as a huge badminton racket stretched above the field, but the racket is not resin fiber but a thick steel cable, not flat but saddle-shaped, similar to potato chips. Therefore, the difficulty of its construction can be imagined.

Functional planning of national speed skating hall.

The National Speed Skating Hall is planned to be located in the south of the Tennis Center (formerly the hockey field of the 2008 Beijing Olympic Games) in Beijing Olympic Forest Park. After completion, it can be used for ice hockey, curling and avenue speed skating, and it is a comprehensive venue. As the ice surface area of the National Speed Skating Hall has reached 6.5438+0.2 million square meters, this ice has become the world's largest multifunctional all-ice surface made of carbon dioxide transcritical direct cooling ice-making technology.

After the Winter Olympics, the National Speed Skating Gymnasium will operate continuously for 365 days, becoming a sports and fitness venue with social service function and enterprise operation similar to the Water Cube and Bird's Nest.
