In the area of infrastructure, Indomitable India always wants to compete with China
But they always get slapped in the face
India's prime minister launched an ambitious program in 2007
It's going to cost 2.1 trillion
To provide 20 million homes for all Indians by 2020
By 2024, that number will reach 60 million
Yet two years on, less than a tenth of the plan is in place
Even the Indian people can't stand it
How can this speed surpass China?
Indeed, in building construction not to mention India, even the United States can do nothing
According to the world high-rise building statistics, in the last year of 2018
A total of 143 new buildings over 200 meters tall, China has 88 buildings
That's seven times the number of Americans in second place
In the construction of skyscrapers, China has maintained a high production position for 23 consecutive years
By 2018, China had 686 tall buildings over 200 meters tall
It's only half of the world, which is a terrible number
But there are objections, despite China's abundance of tall buildings
But most of them are designed by foreign designers
Today we look at designers from China
Personally designed skyscraper- Beijing citic tower
Citic tower is the tallest landmark building in Beijing
Construction started on July 29, 2013, and this year the project officially began to be put into use
It is not as tall as the Shanghai tower
Also less than Shenzhen financial center, only 528 meters
But it set 12 world records and 15 domestic records
The building has a total floor area of 437000 square meters
It has 108 floors above ground and 8 floors below ground
Beijing institute of architectural design personally led the design
The design of the building is inspired by traditional Chinese ritual vessels
The sky is round and the earth is round
So citic tower was also given another domineering name- China Zun
It Show indomitable
China Zun is not from CCTV headquarters
But CCTV building was built by Dutchman Koolhaas
Chinese Zun is the work of a Chinse, Wu Chen
In the CCTV building eight years ago, once the design was announced, Wu Chen criticized it
Don't let China become a laboratory for design architects
Chinese architecture should be dominated by the Chinese themselves
Design the building that accords with Chinese traditional culture
Today, the Chinese statue designed by him has fulfilled this wish
On May 15, 2014, the steel structure project of the Zun building in China officially started construction
Four of the largest steel columns in the world are anchored to huge concrete slabs
These four steel columns and 13000 tons of steel structure parts will become the solid foundation of China Zun
After half a year's foundation construction, December 19, 2014
The building overground project officially started
And three days and a half of the construction speed of the ground
In the building construction, China Zun used by the third bureau of China construction independent research and development
The third-generation integrated jacking steel platform
The platform has a high bearing capacity and strong adaptability
Three characteristics of intelligent comprehensive monitoring
The jacking module is equipped with 12 fulcrums, and the total jacking thrust can reach 4800 tons
And it's this iron knot that's responsible for three and a half days of Chinese speed
Due to the Chinese Zun and the traditional straight or tapered super-high is different
It shows a concave outline in the middle
This design has the advantage of providing more space
But the construction of the upper convex structure brings serious challenges
It can be said that Chinese Zun is an abnormal building
From the outside, it looks very weak, as if a small earthquake could shake it down
This is in the early structure model design
The designers conducted hundreds of tests using wind tunnels and instruments to simulate earthquakes
Finally, the best mechanical properties were selected
China also became the world's tallest building to withstand a magnitude 8 earthquake
Besides, the concept of ecological civilization was fully considered in the design
By adjusting the structural height and orientation of the building
It can make full use of solar and wind energy all year round
It reduces energy consumption for heating in winter and cooling in summer
A regional energy system has also been set up
Achieve centralized cooling and heating, reduce energy consumption to 60-80 percent
In terms of appearance, the building is mainly composed of flexible arcs
In addition to a durable visual aesthetic effect, but also with the soft effect of the strong
This refers to the strong wig in Beijing in spring, autumn and winter
The curved façade and curved corners minimize wind loads
The roof is designed with a breathable sculpture, which not only presents a unique Chinese style
It also can reduce downwind and cross-wing load and acceleration
After a few years of hard construction by engineers
On August 22, 2017, the top of China Zun structure project was officially capped
The building was gradually started on operation in early 2018
The building has eight floors under the ground
It is also the world's largest underground floor number of super high-rise buildings
The world's first 500-meter jumping elevator allows you to go from the negative eight floors to the top of the building
China Zun was also named one of the top ten contemporary Chinese buildings
With the gradual increase of our population
More skyscrapers will be built in China in the future
