In accordance with the form of curve, the initial geometric logic of saddle hyperboloid roof is naturally formed
. 
After the match, the temporary stands will be removed and the track and field track will be formed in the outer ring of the field
. 
Limited by artificial soil, the height of the mountain is only 48 meters
. 
The ring grandstand and double curved roof completely cover the competition field, forming a happy and warm atmosphere
. 
For example, there is a multi-function hall of similar scale above the water cube warm-up pool hall, which is used as a tennis court everyday
. 
Other reconstructed venues, including water cube (curling), National Stadium (hockey), Wukesong Stadium (hockey), Capital Stadium (short track and flower skating), are precious heritage of 2008 Olympic Games
. 
At the same time, this scheme can effectively control the scale of construction during the games, so as to save investment.
. 
The size of the hall is moderate, and the operating cost is far lower than the large space of the competition hall
. 
The temporary stands are arranged on the east side
. 
Auditorium} biad2 temporary stand / Vice hall according to the bid commitment, the speed skating Hall of the Winter Olympic Games has 12000 seats per hour; the original plan is to keep 6000 seats after the games, and another 6000 seats are temporary stands
. 
About 600 meters to the east of the speed skating hall is Yangshan, the main peak of the forest park
. 
The design goal of the general space competition hall is to provide a multi-functional general space
.
The meaning of “high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain, high mountain
.
The central point of the ceiling is set at about 20 meters away from the ice surface, which can effectively control the volume of the hall
.
After 10 years of wind and rain, it was demolished in March 2017 to prepare for the Winter Olympics
.
The national speed skating hall is a design about “speed”
.
The lower level is for VIP, media, athletes, etc., while the upper level is still for ordinary spectators
.
At the beginning of the design, the conversion of the temporary stands during and after the competition is treated as the core topic
.
The building volume of the speed skating hall is huge, but it should not compete with Yangshan mountain
.
The forest park expands from the east to the base, so that the green space envelops the venues, rather than allowing the urban construction to erode the forest
.
Bird’s nest water cube and ice ribbon the BIAD speed skating hall is located on the west side of the Olympic Forest Park and adjacent to the National Tennis Center in the north
.
Since its completion in 2008, the forest park has become a popular place with beautiful flowers and trees
.
The surrounding forest changes in four seasons, and you can have a panoramic view from the rest hall
.
Only a small number of seats are considered in the deputy hall, which is mainly used as training rink and multi-function hall
.
The plane of the speed skating hall is a complete ellipse, with its long axis in the north-south direction, parallel to the central axis of the Olympic Park, strengthening the symbolic significance of the city’s central axis
.
Ice and speed are combined into “ice ribbon”
.
Source: BIAD guanfangweixin national speed skating hall, the only new ice competition venue for the 2022 Beijing Winter Olympic Games, has been completed, and the venue will be ready for the Winter Olympic test
.
The national speed skating hall is the only newly built ice competition hall in Beijing for the Winter Olympic Games, which is used for road speed skating competition
.
Therefore, the ice rink sinks one floor from the ground, making the building height far lower than Yangshan mountain
.
In addition, a vice hall is planned in the design task
.
It has held all kinds of brand launches, boxing competitions, and even Star Wars new film launches
.
On the one hand, the large-span space after the demolition of the temporary grandstand is suitable for the scale of the auxiliary hall; on the other hand, there is no need to use the auxiliary hall during the games, so the building volume can maintain a single and complete form
.
The outer layer of the core surrounds the audience’s rest hall
.
After the demolition, the space left can form a circular commercial operation space
.
The center of the oval plane of Liu Xinghua, the Organizing Committee of the Winter Olympic Games, is opposite to the center of the arc of West Olin Road, so as to reserve the land on the south side of the site and limit the coverage of the building
.
The top edge of the stand forms a continuous, undulating and coherent spatial curve along the elliptic plane
.
Considering the atmosphere of the venue, a small number of stands are arranged around the venue
.
The design of the speed skating hall integrates key technologies such as general space, super large span structure, free-form surface curtain wall, ice rink energy saving, etc., which provides guarantee for the sustainable operation of the Beijing Winter Olympic Games during and after the games
.
Around the 400 meter speed skating venue, the permanent stands and the temporary stands are arranged in the following three ways: > > > the temporary stands are set in the inner ring around the venue, just like the model of the speed skating Hall of the Salt Lake City Winter Olympic Games
.
It was originally the archery field and hockey field of the 2008 Beijing Olympic Games
.
Through this layout, the speed skating hall also provides a friendly Park interface for the community near lincui Road on the west side, forming a harmonious symbiotic relationship with the National Tennis Center
.
A good atmosphere can not only make the athletes more excited and create a new world record, but also enhance the audience’s good experience of watching the game and fully feel the charm of speed skating
.
But the problem is that the competition hall itself is a simple and clear oval volume
.
During the 2022 Winter Olympic Games, Beijing will undertake all the competition and training tasks of ice sports
.
If the volume of the auxiliary hall is added, the main hall will lose the purity and integrity of a single form
.
The perimeter of the ring is more than 400 meters, it is located on the second floor or higher, and the depth is very short, so it is difficult to form a commercial atmosphere after the demolition of the commercial space; > > > the temporary stands are arranged on one side, and the permanent stands are arranged on the other side
.
The East and south sides of the site are surrounded by the Olympic Forest Park
.
Its basic scale comes from the requirements of the speed skating competition rules
.
Urban public life is increasingly diversified, and with the continuous change of the times, the universality of large space has become a way to deal with the changes of social life
.
After the temporary grandstand is demolished, the use of this space to transform the vice hall and the surrounding ancillary space can provide a very diverse business operation opportunities
.
From the operational function, the vice hall is a good complement to the competition hall
.
The design from the inside out is just like the starting point of the bird’s nest
.
In this way, the space after the demolition of the temporary grandstand is complete and open, and can accommodate large-scale space
.
In the Olympic Park, the bird’s nest, the water cube and the ice ribbon complement each other, making the summer and Winter Olympic legends
.
The concept of universal space was first proposed by Mies
.
This concept attempts to cancel the functional attribute of space, especially refers to a single space with large span and flexible use, which has revolutionary significance for modern large space architecture
.
Around the 400m ice road, the stands are arranged continuously, and the oval plane is used to cut to form 12000 seats
.
Competition hall the competition hall formed by BIAD field, grandstand and roof is like a closed giant refrigerator, providing a precision controlled environment for competition
.
In this way, the permanent stands have to be far away from the venue, so it is difficult to continue to hold speed skating competitions; and the professional and entertainment of the track are insufficient; > > > the temporary stands are arranged in the outer ring of the permanent stands
.
The volume strategy of the building comes from the internal functional characteristics of the stadium
.
The permanent stands are mainly arranged on one side for ordinary ticket holders
.
At that time, the two venues were designed as temporary venues, successfully completing the historical mission of the Olympic and Paralympic Games
.
In 1942, Mies produced a photo collage of the concert hall, which uses the interior of the Glenn Martin aircraft assembly building designed by Albert Kang in 1937 as the background, in which flexible walls and roofs made of wood and steel plate are set, superimposing the concept of universal space
.
In winter, the warm sunshine illuminates the indoor public space; in summer, it can isolate the influence of the external heat on the ice environment of the competition hall
.
It is the north end of Beijing’s central axis from the city to the nature
.
When we combine the challenges of the temporary grandstand and the deputy hall, we find a suitable choice, that is, to form the deputy hall after the temporary grandstand is demolished
.
