What is the concept of urban air space?

Super city is one of the new concepts of urbanism, which is used to describe high population density urban planning and three-dimensional urban management model. On the one hand, the construction of super-high-rise buildings is conducive to making full use of limited land resources, leaving as much open space for the city as possible under the premise of controlling the total construction, on the other hand, it is conducive to shaping the modern landmark urban landscape and rapidly enhancing the image of the city. Can you imagine the buildings in the air in the future? Now mankind's vision for the future has far exceeded everyone's expectations!

The existing "Sky Stadium" in our reality can be described as a small step towards the future sky architecture. It is the Beijing No.8 Middle School Air Stadium near us.

Limited by the campus area, there is no independent standard playground and no place for students to exercise, which is a difficult problem facing many schools at present. However, this problem was solved in Beijing No.8 Middle School. The school recently built a new gymnasium and put it into use. The special feature of this gymnasium is that it has the first aerial gymnasium in China, which is 5.2 meters above the ground. Sky Stadium is supported by 13 long-span concrete beams and columns, with 1 floor above ground and 2 floors underground. The top floor has been used as a school playground, with a 400-meter standard runway and a standard football field. The underground 1 floor is a parking lot, and there is a track and field training track with a width of 8m and a length of130m. There are four basketball courts and two badminton courts on the second floor underground, which can also be used as temporary stage and audience.

What unexpected aerial buildings will there be in the future? The following are the bold ideas of all countries in the world!

American engineers designed cylindrical offshore houses! According to Wired magazine, if millionaires in Silicon Valley are willing to give generously, in a few years, we will have a brand-new understanding of the concept of world citizens: if possible, a group of new world citizens will live in semi-independent countries floating permanently on the high seas. It sounds like a scene from the video game bioshock, but Ocean Home Research Institute is not playing a game. As the first step to create a deep-sea city-state, it plans to build a prototype in San Francisco Bay in the next two years.

Ocean home may become a utopian community. Mainly for the rich who are eager to live outside the nation-state, Patrick Friedman of Google and Wayne Gramrich, the founder of Ocean Home Research Institute, elaborated on the idea of building an ocean home. Friedman and Gramrich hope to spend millions of dollars to build the first prototype by rebuilding and shrinking the existing offshore oil drilling platform. Their design is called "cylindrical platform". Basically, the marine home consists of a reinforced concrete pipeline, and ballast is hung at the bottom of the pipeline, and air or water is filled in the ballast to make the living platform rise or fall. Because the part of the building exposed to waves is minimized, the cylindrical design can help the offshore platform to resist the impact of large waves to a greater extent. In the future marine home, the basic living space of each resident can reach about 300 square feet (about 27.87 square meters). This living space will be located in the pipeline, and buildings and gardens will be built on the top of the platform, and solar panels, wind turbines and satellites connected to the network will be installed. With the rapid growth of the world population, how to accommodate more people in the same space is a difficult problem faced by major cities in the world. Part of the answer may be found in the following design ideas that symbolize the future of the seven major air cities in the world.

Foster Architects' Crystal Island project has just obtained the preliminary design permission from Moscow authorities, and will be built on the Na Gatinaud Peninsula, which is only 4.5 miles (about 7.2 kilometers) from Klimlin. Crystal Island is 65,438+0,500 feet (about 457 meters) high. It is a self-sufficient city with an area of 0.96 square miles (about 2.5 square kilometers), which is four times that of the Pentagon, where the US Department of Defense is located. It will have many uses. This huge building has 900 apartments and can accommodate 30,000 people. At the same time, it also has 3000 hotel rooms, cinemas, theaters, shopping centers, fitness centers and international schools that can accommodate 500 students. Visitors can see the streets and alleys of Moscow from the observation deck 980 feet (about 300 meters) high. When completed, Crystal Island in Moscow will have one of the largest atriums in the world. This atrium will be opened in summer, when it can adjust the temperature of the public space 500 miles (about 800 kilometers) high in the building.

The height of the pyramids in Tokyo 2004 is 12 times that of great pyramid of giza. The Egyptian great pyramid of giza is 6574 feet (about 2003 meters) high and covers an area of 3 square miles (about 7.8 square kilometers). The whole building * * * has eight floors, overlapping each other, with an estimated total area of 34 square miles (about 88 square kilometers). Each floor consists of several smaller pyramids, each about the size of Luxor Hotel in Las Vegas. The first to fourth floors are dedicated to accommodation and business activities, and the fifth to eighth floors are used for social places such as leisure and entertainment.

Shimizu "Sky City" can accommodate 750,000 people, which is equivalent to the total population of Tokyo120,000116. It is a great challenge to solve the travel problem of so many people. However, a convenient transportation system and a fast-moving network of sidewalks and elevators connect the whole city through 55 transportation hubs, which not only achieves zero carbon emissions, but also effectively solves the problem of residents' travel. The front of this super building is covered with photoelectric coating, which can convert sunlight into electricity, thus contributing to a greener city.

Tokyo x? Seed 4000 skyscraper, as an architectural concept, was first put forward in 1995 with the original intention of attracting the attention of designers who put forward this grand blueprint. Nevertheless, we still think that x? Seed 4000 is an extraordinary architectural design, even though it may stay on the drawing board forever and cannot become a reality. x？ Seed 4000 skyscraper is 13 123 feet (about 4000m), even Mount Fuji is eclipsed by it. The iconic shape of Mount Fuji has always been praised by architects as the source of their creative inspiration.

The cost of this super structure is 1 trillion dollars, and it looks like a tent supported by huge columns, each of which can accommodate people. x？ Seed 4000 skyscraper * * * has 800 floors and covers an area of 26 square miles, which can accommodate 500,000 ~ 1 10,000 people. Of course, we still need to develop various technologies to realize this huge plan that stays on the drawing board. This construction project includes a new generation of convenient transportation network, high-speed elevators and a system that can slow down the huge fluctuations of temperature, wind speed and air pressure in the whole building.

x？ Seed 4000' s energy supply is entirely from solar energy, but it is not clear whether solar energy is generated by photovoltaic panels covering the facade or by a new generation of thin-film solar panels. The interior of the building will indeed follow the architectural principle of harmony between man and nature; As the picture shows, there is no shortage of green plants in the building. The question is who wants to live in the shadow of a huge building 2.5 miles (about 4000 meters) high all the year round? Then I'm afraid we can only put metal.

1000 (Tokyo's Sky City 1000 is a city with a height of 3280 feet (about 1000 meters). The whole city can be self-sufficient. It was first proposed by Takenaka Corporation in 1989 to help restore the green space in the traffic jam area of Tokyo. If Takenaka's plan to solve Tokyo's traffic problems is finally passed, we may see a city that completely conforms to the concept springing up in Tokyo. City in the air 1000 consists of 14 platforms protected by glass, covering an area of 3. 1 square mile, and will have a large area of green space.

The whole building has a variety of uses, which can accommodate 36,000 permanent residents and 654.38+10,000 laborers. There is a vast space for running schools, opening shopping malls and building cinemas. At present, a new generation of three-story elevators is being developed, which will become the backbone of the city in the air 1000 transportation system. It only takes 2 minutes for people to go from bottom to top. Theoretically, the city in the air 1000 can reclaim land and turn it into green space, thus alleviating the high temperature that people often see in Tokyo. At present, this project is still in the proposal stage, but the Tokyo authorities attach great importance to it. City in the air 1000 may become the first eco-city in the world.

The Millennium Tower in Tokyo, Japan is 2755 feet (about 840 meters) high and has a conical appearance. 1989 was first put forward by foster architects to solve the problems of land shortage and overpopulation in Tokyo. According to the plan, the Millennium Tower will be built on the coast of Tokyo Bay 1.2 miles (about 1.9 kilometers), with a height of 1.70 floors and an area of 0.4 square miles, which can be used for business and residence. The Millennium Tower can accommodate 60,000 people and has a high-speed subway network, which can accommodate 160 people at a time, ensuring the normal travel of local residents. There is a transfer station on every 13 floor of Millennium Tower, and the bus system connects these transportation hubs, where passengers can get on and off, or transfer to elevators and moving sidewalks. The wind turbine of Millennium Tower and the solar panels installed on the upper floor can provide sustainable energy for the whole building, which is one of the most environmentally friendly and ideal urban design schemes put forward at present.

Cui Yuejun, a Chinese-American architect and urban and regional planner, is famous for his passion for future giant buildings. The Ultima Tower designed by Cui Yuejun is 2 miles (about 3.2 kilometers) high and can cope with the population explosion in San Francisco where land is scarce. The ultimate tower in the design concept has a base with a diameter of 6,000 feet (about 1 1,830 meters), with a total space of 53 square miles and 500 floors. Seen from a distance, it looks like a huge cone. Cui Yuejun's "Ultimate Tower" shows the design concept of a vertical city with a population of 6.5438+0 million, reaching or even surpassing any previous similar design scheme.

Solar absorption panels and wind turbines are installed on the facade of the ultimate tower, and a technology called "atmospheric energy conversion" is adopted to generate electricity by using the pressure difference between the roof and the bottom of the building, which will provide this futuristic giant building with stable energy all the year round without causing any damage to the environment. Once completed, the tower will eventually have an open green space on the floors from 100 to 165 feet high. The unique laminated design makes people feel open and bright at this height. It is worth mentioning that although the ultimate tower is several kilometers high, guests can climb from the bottom of the building to the top in less than 10 minutes by taking an elevator with a speed of 3 miles per hour.

The design concept of bionic tower as a vertical city has aroused great interest in Hong Kong and Shanghai with high population density. If this design scheme is finally passed, a skyscraper with a height of 3950 feet (about 1 200m) and a total internal area of 0.8 square miles will rise on the land of Hong Kong or Shanghai. Chaoqun Building, with a height of 300 floors, will be built on an artificial island with an area of about 0.4 square miles, which is connected with the inland, so that 654.38+million people can live and work here. Both Hong Kong and Shanghai have the highest population density in the world. How much will it cost if Chaoqun Building is built in this city? The answer is1500 million dollars.
