Analysis: prevention and control of self - explosion and fall of building glass curtain wall
It is reported that China's existing glass curtain wall reaches 200 million m2, and most of the buildings above 400m have chosen curtain wall structure system. However, the glass curtain wall implodes from time to time, fall accident happens frequently, below and small make up look at the prevention and control measure of glass curtain wall from time to time explosion and fall together, reduce the occurrence of quality accident as far as possible.
Design and construction factors
(1) the specification of the glass curtain wall stipulates the size of the groove at the edge of the glass, which is to ensure the free expansion of the glass under the influence of temperature change and other factors. In case of any factor that hinders the free expansion of the glass, even small diameter solids such as nails will break the glass.
(2) both sides and bottom of the groove of the glass cannot be filled with hard materials. The volume change of these materials will crush the glass and break the glass.
(3) under the action of plane external force, the glass will be warped under the influence of wind load, and the glass will be broken if the sealing material hinders the warping change of the glass.
