With the continuous development of the times, if you want to know the economic level of a city, you must look at the high-rise buildings in the city. According to relevant reports, China's current high-rise buildings account for 53%, and China is also the world's largest distribution of high-rise countries. How tall does it have to be to be called a high-rise building? Civil buildings that do not contain residential buildings, with a height of not more than 24 meters, are single-storey buildings and multi-storey buildings. If the height is higher than 24 meters, it is a high-rise building, and if the height is greater than 100 meters, it is a super high-rise building. Now there is news that the "height limit order" is coming, and many high-rise buildings are about to depreciate, and experts say that there is a lot of trouble this time.
High-rise buildings
The reasons why ordinary people like high-rise buildings are as follows: First, high-rise buildings can now bring very obvious social benefits. Urban planning is to reduce the area of usable land, but also to reduce municipal construction investment and shorten the construction period. The second point is that the view of high-rise buildings is very good, the speed of air circulation is also fast, and the air quality is better the higher, so the price gap between the high and low floors of many houses is very large. Third, the higher the floor, the smaller the incidence of pests such as flies and rats. The lower floors are generally very humid, so the price of the lower floors is also relatively low. Generally speaking, the elderly will choose the first floor, because it is more convenient for the elderly with bad legs and feet to go up and down the stairs, and most young people will not choose.
Less secure
But there are two sides to everything, and there is a good side and a bad side. In addition to the above advantages, the top level must also have shortcomings. Some experts said that in fact, the top level is very troublesome. When building high-rise buildings, some cities do not consider the practicality and rationality of buildings at all, do not build according to the height planned by relevant departments, and blindly compare with other buildings. In recent years, the news of high-rise fires has emerged one after another, and many owners have lost a lot of their property, even involving their personal safety.
Safety has always been the top priority in high-rise buildings, and the higher the height of the building, the more it is necessary to ensure the functional problems of the building. Fireproof materials and safety systems for high-rise buildings are very important, but this has always been a problem for the relevant departments. The internal and external facilities of high-rise buildings are also very important, and once a high-altitude falling object occurs, it can be a concussion or an unimaginable consequence. Although the air in the upper floors is good and there are few mosquitoes, if there is a power outage and water outage, it is very inconvenient for people, not to mention what will happen to the elderly who encounter these problems upstairs.
The ground floor is in high demand
The policy of "height limit order" has been introduced, and the sales of many high-rise buildings have repeatedly declined. High-quality, low-rise dwellings are now popular with the public. The price of low-rise buildings is not too high, and the materials, design costs and urban locations are relatively close to the people, because of the low floors, and the high floors are just the opposite. Even if the power and water on the low floor are cut off, the owner will not be tired on the next trip to the building, which will not bring great trouble to the owner.
Low-rise buildings will be cooler in the summer, because they are closer to the ground and there will be trees outside, so the indoor temperature of some buildings will be lower. Even if there is an earthquake, fire, etc., everyone can evacuate indoors on the ground floor. The chances of escape are much greater than those at the top. If there are children in the house, the upper level is very dangerous, if you forget to close the window, the consequences are unimaginable. The bottom layer is friendly to both children and the elderly. Then again, choosing between the top and the bottom mainly depends on the individual's ideas, after all, nothing in the world is perfect.
