Problems of glass curtain wall

In recent years, the glass curtain wall was once known as the "air killer", this is because, for example, Hangzhou and Shanghai in 2011 occurred in Nanjing and other places of the glass and the glass falling rain event, this is a good proof, but the glass curtain wall where exactly is the problem?

"The problem is the glass strictly." director of aluminum door and window curtain wall board Chinese Construction Metal Structure Association Huang Qi said that in the aspect of China's glass indeed made a few detours. Before does not ask for toughened glass, and later forced to use, and early understanding of the toughened glass is also a problem.

The glass blew was also the famous architect Forster called the "glass curtain wall cancer. Tempered glass curtain wall is in under the action of forces rupture, the fundamental reason lies in the tempered glass explode containing nickel sulfide and other impurities in glass, produced by the sun in the expansion temperature change after, resulting in glass explode.

There are many reasons for the glass explode, one of the many reasons. It is a great relationship among the point type glass fittings for use and the use of glass curtain wall glass explode. When the barge and toughened glass joint fittings connection, some glass hole needs to be opened, the glass damage is great. The whole structure the glass caused some impact, coupled with the expansion in the sun shines on the temperature changes, which leads to self destruct. At present, the glass and the glass connecting connector has two kinds, one is opening the curtain wall joint, differentiated countersunk head and floating head, the other one is glass free hole connector, the free hole connector appearance, stainless steel joint shape ratio and openings, is also used for air, high-rise buildings, and use glass rib splint. While using the free hole connector of the glass curtain wall, The glass blew the possibility will be much smaller. Because of the use of this connector only at the edge of the glass clamp glass, no hole, no overall structure of the glass damage. So the use of the free open connector is conducive to the prevention of high-level glass breaking events.
