Shenzhen glass curtain wall crashed and injured four workers

At 5 pm on June 27th, 2016, a glass wall of about 5 square meters on the 5th floor of the northwestern side of the Ping’an Mansion, the tallest building in Shenzhen, will be completed. It will suddenly bruise and injure four workers on the scaffold on the first floor, causing two serious injuries. Minor injuries.

Why did the glass curtain suddenly burst? Mr. Dong, an injured worker, said: The sudden explosion of the glass curtain wall was due to the fact that the sun was very strong at that time. The sun was shining on the glass curtain wall and the temperature of the glass surface continued to rise, causing the glass to burst. In addition to the glass cracking due to high temperature factors, several other workers suspected that there is a safety issue in the glass material at the bottom of the Ping'an Building. With regard to this issue, Shenzhen's safety supervision department has been involved in the investigation.

So how can we buy safe and reliable decoration materials? Reporters visited the nearby decoration materials market and found that the price and quality of decorative materials on the market were uneven. When reporters distressed about how to identify the quality of materials, Mr. Wang, who was buying decorative materials, told reporters that he was a decoration company. The operator, who deals with decoration materials all the year round, generally fixes on several decoration materials companies to purchase materials, one of which is Zhongshan Youwei Site Decoration Materials Co., Ltd. Mr. Wang said that the company’s service and product quality are all First-rate, he has already purchased materials at the company several times.

Glass curtain wall material selection should pay attention to the following points:

1. Choose a formal qualified decoration material company. It is best to choose products that have passed the US ASTM E84, SGS fire detection and gradually be recognized by domestic customers. Products are widely used in star-rated hotels.

2. Glass curtain wall materials should be made of materials with high safety factor, high temperature resistance, and shockproof properties. In addition, the material can be arbitrarily shaped, breaking through the two-dimensional limit, not rebound without deformation, bending position is not white even better.

3, glass curtain wall materials to choose aging, anti-aging decorative materials, in order to effectively improve the service life of translucent panels.

4. In addition, according to relevant investigations and studies, the self-explosion of tempered glass mainly depends on the thickness of the glass. The thicker the glass, the greater the potential for potential defects. At present, the thickness of tempered glass on the market is 8mm, and the probability of glass blew within one year is about 1%, and the risk factor is quite high, so a slightly thinner tempered glass can be selected.
