China no longer builds new high rise buildings above 500 meters, so why restrict the construction of

Nowadays, there are some high-rise buildings in the metropolis, so that they can represent the prosperity of a city. And many cities will have even hundreds of floors of landmark buildings, so there will be a lot of super tall buildings. And in 2022***.

A policy has also been announced, that is, an explicit decree has been issued prohibiting buildings in our country from being built above 500 meters. Even if there is a design, it will not pass, which means that there will be no more supertall buildings in the future. And for those super-tall buildings that have already been built, they have really become landmarks.

China not only prohibits the construction of buildings above 500 meters, but also strictly reviews and restricts some buildings at a height of about 250 meters. In fact, in China, if the building exceeds 40 floors and the building reaches more than 100 meters, then it is a super high-rise building.

China controls super high-rise buildings very strictly, because it is responsible for the safety of high-rise buildings, so that there will be no buildings in China to climb the heat. While tall buildings are a symbol of prosperity in the metropolis, supertall buildings are almost in the clouds. <

It also makes people look down on the whole city from mid-air, but in fact, the state does this on the one hand to save money, which can also play a role in avoiding overconstruction. Because many super high-rise buildings, the proportion of utilization rate has not been reached, so there is no need at all. And after the construction, there will be some areas that will be vacant, which is very wasteful.

Moreover, the difficulty of super high-rise buildings will be greater than that of ordinary buildings, so the state will also consider the safety and service life of buildings. <>

Not only that, but if you want to build a super high-rise building, then the cost is also very high, especially as a landmark building cost is very surprising. Moreover, super-tall buildings generally need to use elevators, and there is no way to climb so many high-rise buildings by relying on manpower. If there is a power outage, you need to go downstairs, which takes a lot of time and is dangerous.

There will also be many problems in daily maintenance, fire safety, escape routes, which will increase the difficulty, so this behavior of the state is also very correct.

First of all, excessively high buildings have certain standards for construction requirements, which can easily cause waste to some extent; Secondly, ultra-tall buildings are prone to safety accidents; Finally, in the case of changes in urban development, supertall buildings will hinder municipal construction.

It should be that there is a fear that if the floor is built too high, the safety problems caused by it will also increase, in order to further ensure the safety of the high floor.

The reason why the state wants to prohibit the construction of super-tall buildings is to save money and avoid excessive construction. The utilization rate of many super high-rise buildings cannot reach a certain proportion, and if it is not necessary, after the completion of construction, it is easy to have a large area of vacancy, resulting in waste. Moreover, it is very difficult to build, and the state also has to consider the safety and service life of the building.

It is because a building that is too tall will affect the flight of an airplane in the sky, because an airplane has a normal altitude for flying, and if there is a building that is too tall in a city, then the plane will accidentally hit the building when it lands.

This is because if the building is particularly high, it may cause the building to collapse when it encounters some dangers, and secondly, if the building is too high, it is also particularly dangerous.

First, the cost of construction will increase as the number of floors increases; Second, the high-rise building itself is more cumbersome to maintain; Third, high-rise buildings must use elevators, which are prone to accidents.

As we all know, there was a recent news announcement that no new buildings of more than 500 meters were allowed to be built in various places, and everyone was very curious about this news. Many places are very obsessed with high-rise buildings, and the high-rise fever that is all the rage has finally cooled down.

1. It is very dangerous to build these super-tall buildings of more than 500 meters. In fact, it is very dangerous to build these super-tall buildings of more than 500 meters. First of all, we know that the higher it is, the higher the center of gravity, which means that the building will become more and more unstable.

If there is a fire or something, the firefighters will not be able to reach such a height, so it is completely unnecessary to build a high-rise building, and there is no need to pursue this height.

Second, many places regard the construction of high-rise buildings as a manifestation of urban economic development. There are many places where the construction of high-rise buildings is regarded as a manifestation of the economic development of a city. Like many developed countries, they are very fond of building high-rise buildings, giving people a sense of grandeur.

The safety of high-rise buildings is very tricky in the first place, especially fire safety, the height of these high-rise buildings is the height that the fire ladder can not reach, once there is any accident, there is really no way to rescue.

Third, we don't need to build such a tall building. It is also very unsafe to build a high-rise building, and in the event of a natural disaster, the scope of such a huge high-rise building is very large. We also know that some time ago there was a building in Shenzhen that shook the phenomenon, it really makes people feel very terrible, such a high building has appeared such a scene, if the floor is higher, it is likely that the top floor will sway from side to side, it really makes people feel very terrible.

We can't fully improve the stability of tall buildings, so we don't need to build such tall buildings.

First of all, it is forbidden to set up shopping malls on the third basement floor of high-rise buildings, secondly, no shops are allowed to be set up in the atriums of high-rise buildings, and then children's activity areas should be set up on the first to third floors.

It is forbidden to set up shopping malls on the third basement floor or below of high-rise buildings, and it is forbidden to set up public entertainment venues on the second basement floor or below of high-rise buildings. Children's activity venues in high-rise buildings shall be set up on the first to third floors, and independent evacuation stairs and safety exits shall be set up. High-rise residential buildings shall not illegally set up business premises.

The first stipulation is that new buildings of more than 500 meters are generally not allowed, and the second is to strictly strengthen the approval procedures and approval standards for buildings of more than 100 meters, and to qualify and standardize the construction of urban land!

The reason is that it has a bad impact on the environment and the economy, and high-rise buildings will interfere and pollute the microclimate.

The higher the distance the building is built, the more wind loads and the amount of steel used, resulting in an increase in the cost of the overall structure, which to some extent increases the additional expenditure and economic cost in some urban areas.

The main reason is that there are too many hazards caused by high-rise buildings, and in recent years, there have been many accidents caused by high-rise buildings.

If we continue to build super-tall buildings of more than 500 meters, I think there will be a great danger, and the higher the buildings now, not only will the image of the city be affected, but more importantly, it will also cause some damage to the ecosystem. Therefore, in order to comprehensively consider and ensure the stable development of China's real estate industry, this policy will be introduced. If the government does not impose strict restrictions in this regard, I believe that future buildings will gradually collapse as they age, and if such a dangerous accident occurs, it will definitely have a big impact.

As human industrial civilization is constantly improving, the country's infrastructure level is also improving. Many cities have built skyscrapers in pursuit of high efficiency and economy, and even in first-tier cities such as Shenzhen, Shanghai, and Beijing, many buildings even exceed 100 meters. Because these buildings not only effectively promote the development of the city's economy, but also can better help people solve a dilemma of land shortage.

As the population increases, the land area in the city is decreasing, which exposes the serious contradiction between people and land, which is why many buildings are getting taller and taller.

If you look at it from a security and long-term perspective, I think this decision by the NDRC is a very correct thing. Because restricting the construction of super-tall buildings above 500 meters is not only responsible for the safety of more people's lives, but more importantly, for the sake of the city's economic development, because once such super-tall buildings are built. Not only does it have to invest a huge amount of money, but the entire project is invested for too long, which may directly affect the revenue of the project.

Therefore, this order will be issued after comprehensive consideration.

Summary: The emergence of super high-rise buildings effectively solves the tension between people and land, and also reflects the level of infrastructure in a country. While ensuring the economic operation of the city, we must also carry out coordinated development, so that there will be no problems.

The higher the height of the building, the more difficult it is to build, the higher the maintenance and management requirements, and the greater the risk of safety and fire protection, which brings great difficulty to accident rescue.

This is because super high-rise buildings are not very safe, there are many safety hazards, and it is particularly troublesome if you escape, so such a regulation will be issued.

This is because the ultra-high buildings above 500 meters are very unsafe, and lightning rods need to be installed on them, which is very dangerous in windy weather, so they are not allowed to be built.

China is very keen to build super high-rise buildings, and on the surface, high-rise buildings have greatly increased the land utilization rate. Construction insurance, high, collar. Why is it proposed to limit the height of buildings?

First, there are too many security risks. Because of the blessing of elevators, the number of floors in residential buildings has been rising over the years, and it is not uncommon for residential buildings with three or four floors to be built. And with higher and taller buildings comes more and more hidden dangers.

Yes, the first is the safety issue, usually the higher the building, the higher the requirements for materials and construction, the seismic technology, the technology of fire-fighting facilities is more complex, the project cost and operation and maintenance costs are also higher, the slightest mistake in the whole project will cause irreparable consequences, and once there is a fire, ** and other accidents, it is difficult for residents of high-rise buildings to obtain an effective escape route to escape, and the evacuation time is too long.

Second, it increases the difficulty of follow-up rescue. At present, the highest operating height of fire trucks in the world is 100 cm, and in fire fighting and rescue, the actual effective fighting height of fire trucks is generally less than 50 meters. In addition to safety factors, the construction of ultra-tall buildings is difficult to avoid losses and unfinished dramas because of the difficulty of construction and the need for a huge capital chain.

Third, dense high-rise buildings will bring a sense of psychological oppression to people. As far as the eye can see, the whole city has become a concrete forest, and it seems to have entered the imaginary space of cyberpunk, which is suffocating, and everyone should feel the same way.

Fourth, polluting the environment. Supertall buildings also have problems such as increased traffic congestion, light pollution and heat island effects, unfavorable wind conditions, and land subsidence, although we can't break the record for the tallest building.

Fifth, save construction costs. In order to live a better life in the future, it is still necessary to limit the height of buildings, and this policy allows developers to start from the perspective of actual building utilization rate, thereby reducing energy consumption and construction costs, and saving money for infrastructure construction, which is in line with urban development.

Because there are hidden dangers in fire protection, it cannot meet fire protection standards at all, and light pollution is very serious.

Because there are hidden dangers in fire safety, it cannot meet the safety fire protection standards at all, and there will be serious light pollution.

Because this situation is very dangerous, once there is a problem, then the fire ladder can not reach, this height, it is also difficult to rescue.

Because if the floor is too high, there is a high risk that will put people's lives at risk.

Reporter Pang Wuji) China plans to strictly control the height of buildings, and super high-rise buildings above 500 meters may be banned.

China's Ministry of Housing and Urban-Rural Development solicited public opinions on the "Notice on Strengthening the Planning and Construction Management of Super High-rise Buildings (Draft for Comments)" on the 10th.

The draft proposes to strictly control the height of buildings. All localities should strictly control the construction of new super high-rise buildings. Generally, no new super high-rise residential buildings are allowed.

Specifically, cities with a permanent population of less than 3 million in urban areas are strictly restricted from building new super high-rise buildings of more than 150 meters, and no new super high-rise buildings of more than 250 meters are allowed.

Cities with a permanent population of more than 3 million in urban areas strictly restrict the construction of new super high-rise buildings of more than 250 meters, and no new super high-rise buildings of more than 500 meters are allowed.

The draft proposes that when relevant local departments approve construction projects of residential buildings of more than 80 meters and public buildings of more than 100 meters, they should send them to local fire and rescue agencies for comments to ensure that the local fire and rescue capabilities are matched.

This is not the first time that China has taken a stance on strict control over new supertall buildings. The Ministry of Natural Resources previously issued the "Guidelines for the Preparation of Municipal Land and Space Master Planning (Trial)", which also proposed to strictly control the construction of new super high-rise buildings.

In recent years, the "height" of China's urban buildings has also "grown" upwards with the rapid development of the economy, with more and more super high-rise buildings emerging and the height of the city skyline increasing.

But there are risks involved. The draft for comments points out that some cities are building super high-rise buildings and blindly pursuing height.

First, the form is peculiar, detached from actual demand, raising the cost of input, aggravating energy consumption, and increasing the difficulty of safety management. Industry experts also pointed out that super high-rise buildings not only cause a waste of resources and great safety hazards, but also cause a thousand cities and the same urban style.

In this draft for comments, it is clear that the lifelong decision-making responsibility system for super high-rise buildings will be implemented. New super high-rise buildings of more than 150 meters in cities with a permanent population of less than 3 million in urban areas, and new super high-rise buildings of more than 250 meters in cities with a permanent population of more than 3 million in urban areas, shall be reported to the city party committee for examination and approval as a major public construction project, and the responsibility shall be investigated for life.
