Theoretical discussion on the mechanism of self explosion of tempered glass
1, self tempering of tempered glass is an important problem for the safety of glass curtain wall. But for the concept of safety glass, the traditional concept is that (all) toughened glass belongs to safety glass. In addition to its high strength, the main reason is that all glass blocks are broken into honeycomb shaped obtuse grains when broken. Through the investigation and the practice of many accidents, this concept has been questioned. It is necessary to discuss the use of safe glass in the glass curtain wall of high-rise buildings. For high-rise building glass curtain wall using safety glass, the main concern of its safety is broken glass falling and hurting people. There should be three requirements here:
The first is that the glass has enough strength to withstand the design load.
The two is that if the glass breaks down, it has to be shattered and shattered so that it will not fall down when it is in a broken state.
The three is enough fracture toughness K1C.
2, (toughened glass) has two safety factors: high strength and its failure shape as obtuse small particles. But it does not have the key safety factors for the glass curtain wall of high building, which is not safe and scattered, and the unsafe consequences of it. The leading cause of this is the gravity acceleration of free falling bodies. The glass of tall building glass curtain wall, no matter what kind of glass fragment, such as falling down on high-rise buildings, is dangerous or even fatal. In addition, there is no premonitory damage to the self blasting of the tempered glass. At present, there is no effective method to prevent the glass from being completely prevented. It is a cancer of glass curtain wall, broken glass self blasting and high altitude, and the glass curtain wall of high building is not safe to use (full) steel glass.
Safety is a relative concept, conditional, not absolute and unconditional. Out of use conditions, it is not comprehensive to define glass curtain wall safety glass only from its debris form. The tempered glass is not unbroken, only the glass is smaller, but the debris is easy to fall and spatter, causing accidents. Therefore, the glass curtain is clearly defined in many technical standards and specifications of the glass curtain wall abroad. Monolithic steel glass should not be used in the wall. The anti flying glass should be used. The glass curtain wall of the Japanese high-rise building is used (full) of steel glass. A layer of anti flying film must be added to ensure safety.
"Strong but not broken, broken, not scattered", anti fly glass is the safety glass used for glass curtain wall.
