On December 25, the national speed skating pavilion, a landmark building of the Beijing 2022 Winter Olympics, was completed. The “Ice Ribbon” has really managed to fly, the “curtain of heaven” has been woven and the ” faster ice “and the” pavilion of wisdom “will also be on stage.” During the Winter Olympics, the National Speed Skating Stadium will host speed skating competitions and 14 gold medals will be awarded.
3360 pieces of glass are assembled into “ice tape”
The main stadium of the National Speed Skating Stadium has a construction area of about 80,000 square meters, a height of 33 meters and has a capacity for about 12,000 spectators. In appearance, the National Speed Skating Stadium is surrounded by 22 curved glass “ribbon” glass curtain walls, which is why it is also called “ice ribbon”. Ding Jianming, deputy director of the Municipal Office of Major Projects, introduced that the finished “Ice Ribbon”, the majestic steel structure “Bird’s Nest” and the flexible membrane structure “Water Cube” complement each other, forming the world’s first “Double Olympic City” in Beijing. The iconic building complex.
It was seen at the scene that staff were debugging and cleaning equipment on and off the premises. After the completion of the speed skating hall, the façade will also be illuminated at night, when citizens can see the magnificent scene of the “ribbon dance”.
According to Li Shaohua, project manager of the National Speed Skating Hall General Recruitment Department of Beijing Urban Construction Group, to create a light and elegant tape effect, the facade of the National Speed Skating Hall is assembled by 3360 curved glass units. Each piece of glass used in the curved curtain wall is a different size, all of which are customized at the factory and installed on-site through BIM building information modeling technology.
The hyperboloid saddle-shaped single-layer cable net structure roof design adopted by the National Speed Skating Stadium can greatly save materials, and the consumption of steel is only a quarter of the traditional roof . Li Shaohua said that they called this cable network “the curtain of heaven”, and the process of building the ceiling cable network is like “weaving the curtain of heaven.”
“Fastest Ice” is open to citizens after the game
As you enter the National Speed Skating Hall, the blue wall echoes the alternating dark blue and light blue seats, and a concrete floor of approximately 12,000 square meters is laid out flat in front of you. It is reported that in January 2021, the stadium will begin the first ice-making works.
The National Speed Skating Stadium adopts an all-ice design and is currently the largest ice surface in Asia. It is also the largest ice area in the world using a direct transcritical carbon dioxide cooling system. “The carbon dioxide cooling is very uniform, and there will be no different temperatures or uneven hardness of the ice surface. It is a key factor for high-level competitions like speed skating.” Deputy General Manager, National Speed Skating Stadium, Chief Engineer Li Jiulin announced that in 2021, the stadium will adopt a sub-module control unit, which can divide the ice surface into various areas. According to different projects, the ice is made according to different areas and standards. The “faster ice” will also be made.
The reason for adopting the ice design is to fully consider post-game use to provide hardware support for a massive fitness meeting various needs. Li Jiulin said that the stadium can host more than 2,000 citizens at the same time to perform all ice sports such as ice hockey, speed skating, figure skating, curling, etc., and achieve sustainable use after the match.
Create smart places to watch AR games
The National Speed Skating Stadium is still a completely smart stadium. Li Jiulin explained that, based on the construction of the 5G network, the stadium has introduced technologies such as “integrated interior and exterior positioning and navigation systems”, which is like equipping the stadium with a “brain”. With a “smart brain”, the National Speed Skating Stadium will provide spectators, event organizations and participants with a high quality visual experience and full service guarantee in the future.
“For example, public-facing services will all be built into one APP in the future. The public can route and guide the seat from outside the venue to the venue on their mobile phones, and clearly see the catering and services. to the consumer on and off the venue. The APP can also provide AR to watch games. Experience, present the historical performance of athletes in the competition field, etc. “Li Jiulin introduced, in a fixed seat, the audience can only watch a sports scene within a visual range, but through advanced information technology such as AR, the audience can see the whole scene The effects of sports and events.
Li Jiulin revealed that current laboratory research work related to smart places has been completed in order, and related equipment and systems have started to be implemented at the places. In the future, the National Speed Skating Stadium will become a smart place and a multifunctional venue that integrates sporting events, mass fitness, cultural entertainment, exhibitions and social well-being.
