"ice ribbon". It is named "Ice Ribbon" because the exterior of the venue is surrounded by 22 ribbon shapes and curved glass curtain walls, which is like the sliding trace of speed skaters' skates. At the same time, 22 also represents the time of the 222 Beijing Winter Olympics.
Jia speed skating hall covers an area of about 17 hectares. In addition to the underground parking lot, the construction area is about 8, square meters. The venue is surrounded by 22 light belts like "ice ribbons". There are 12, seats in the venue. The venue is about 18 meters from east to west and 24 meters from north to south, with 3 floors above ground and 2 floors underground. The height of the building is 33.8 meters. There is a standard 4-meter speed skating track.
The "Ice Ribbon" of the National Speed Skating Hall adopts the single-layer bidirectional orthogonal saddle-shaped cable net roof with the largest span in the world, 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 as to realize the "simultaneous operation and different use" of the venues. 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 kept improving its ice slab construction. It took more than 6 days to complete 8574 welds of ice-making steel pipes, and the horizontal height difference of the concrete ice slab was about 4 mm, which was very smooth. The temperature difference of the ice surface is controlled within .5 degrees Celsius, which is beneficial for athletes to create good results. ?
The venue lighting system of the National Speed Skating Hall is tailored according to the functions of the venue, and consists of 1,88 sets of LED lamps. Its optical parameters meet the requirements of holding top-level events and high-definition broadcasting, with outstanding energy-saving and environmental protection performance. Each set of lamps can be intelligently and independently controlled, which can meet the rich lighting needs of venues for multi-functional use during and after the games.
History
The original site of the National Speed Skating Hall was the hockey field and archery field of the 28 Summer Olympic Games, both of which were built as temporary venues. In 217, in order to build the National Speed Skating Hall, two venues were demolished.
The National Speed Skating Gymnasium is the only newly-built competition venue in the Beijing Division of the 222 Winter Olympic Games, and will undertake speed skating competition and training during the Games. Located in the west of the Olympic Forest Park and south of the National Tennis Center, the original site was the archery field and hockey field, which were temporary venues for the 28 Beijing Olympic Games.
On June 6th, 216, BOCOG coordinated the Beijing Municipal Planning and Land Resources Management Committee as the owner of the National Speed Skating Hall to launch the international competition on the architectural concept scheme of the National Speed Skating Hall.
on July 6th, 216, 12 design institutions were formally qualified for the competition after pre-qualification. In the end, the design scheme A4 with the concept of "Ice Ribbon" won, and this competition scheme was created by China architect Zheng Fang. On April 25, 217, the design scheme began to be exhibited in the Olympic Engineering Construction Hall of Beijing Planning Exhibition Hall. In order to solve the problem of post-game utilization, the project also reserved a sub-pavilion in the southwest corner of the venue.
After the Beijing Winter Olympics, the National Speed Skating Hall will become a multi-functional venue for international events such as skating, ice hockey and curling, as well as mass ice activities.
On July 14th, 217, the Press Office of Beijing Municipal People's Government held a press conference on the promotion of the PPP project of the National Speed Skating Hall of Beijing 222 Winter Olympics. The National Speed Skating Hall began to recruit social capital partners to build and operate the venue. The implementation agency of the PPP model of the National Speed Skating Hall project is the Beijing Major Project Construction Command Office, and the government-funded representative is Beijing State-owned Assets Management Co., Ltd..
at the beginning of January, 221, the National Speed Skating Hall started making ice for the first time. On January 22nd, the National Speed Skating Hall successfully made ice for the first time, and successfully made a speed skating track. From October 8 to 1, the National Speed Skating Museum held the "Meet Beijing" Speed Skating China Open, which was the first international competition held by the venue.
