Dangerous buildings are high and 100 feet high

In 1995, the Mitutoyo Department Store in South Korea collapsed, and more than 1,500 people were buried. After decades of investigation, the reason is finally clear.

First of all, the construction is careless. The "backbone" of the whole building - the force column was changed from the 80cm diameter on the drawing to 60cm, and the load capacity of the column was reduced by several tons. What makes people even more laughable is the steel bars in the columns, which have been artificially reduced from 16 to 8. This "stolen beam" is very capable! The burial depth of the steel bars in the floor is changed from 5cm to 10cm. This series of technical errors has caused the building load factor to be reduced by half. The building is for people to use. It carries the happiness of countless families. The building problem is not a child's play. Instead of letting it become a hidden danger from the beginning, it will kill it in the cradle!

Secondly, the management executives are interested in their hearts. When the building is about to be completed, in order to increase market competitiveness and expand profits, the fifth floor of the original four-storey building will be added as a restaurant. Because Koreans like to sit on the ground, the floor heating in the restaurant has further thickened the thickness of the floor of the fifth floor, making the originally fragile building even more precarious. The development of the commodity economy, the sinful desires, the money can shake everything. "There is money to make the ghosts push." ​​The executives of the department store, with their blindfolds, glaring at the point of change in their hearts, are willing to do the ghosts.

Again, careless air conditioning transfer machine. As three large air conditioners were accused of disturbing the people, Sanfeng Department Store decided to remove the three air conditioners. However, in order to hurry, the three air conditioners were not lifted to the correct position, but simply mounted on the pulley and pushed over. When the air conditioner of 15 tons is moving, it is forced by the support column to crack the support column and the building body. Since then, the air conditioner has been running continuously for a long time, causing the crack to become bigger and bigger. Finally, the last straw overwhelmed the camel and the disaster occurred.

After the disaster, the South Korean government immediately carried out the rescue, but the loss could not be remedied, and the lost life could not be reproduced. Although the South Korean government used the legal guidelines to take responsibility for the responsible persons of the collapse of the building, everything was late. Subsequently, the South Korean government conducted a census of high-rise buildings across the country. But the results are shocking: one-seventh of the high-rises need to be rebuilt, 80% of the high-rises need to be overhauled, and only 2% of the high-rise buildings are qualified. Can China's high-rise buildings also qualify for China? Can we have the ability to complete this census rescue work and have the power to make this result public? Can you chase after descaling?

Today, in the high-rise buildings, we have to strengthen our awareness of self-protection and improve our self-protection ability.

If a country wants to continue to develop and the people live and work in peace and contentment, they must adhere to integrity, know the law and abide by the law, and seek truth from facts.
