Fire-resistant glass systems technology - fire-resistant glass walls and partitions

Glass curtain wall permeability increases the way the spread of fire, smoke and fire when the fire spread to the adjacent floor along the outer wall and the inner walls, having the fire spread quickly, the smoke flow rapid evacuation fighting difficulties and so on. Fire and fire-resistant glass curtain wall design requirements, should follow GB12513 a 2006 "glazing element fire test method", GB15763.1 a 2009 "architectural safety glass - Part I: fire-resistant glass", GA97 1995 a "non-load-bearing fire glass partition relevant provisions of the wall general technical conditions ", etc., curtain wall structure must have the same fire resistance and fire-resistant glass, also has good smoke sealing performance. It should form on exposed frame glass curtain wall structure fire. Its fire protection design shall not affect the permeability and ornamental on the basis of using fire-resistant glass and fire-resistant steel frame. Precision steel sections have a high quality appearance and texture, can constitute an independent fire-resistant glass curtain walls; high temperature properties of the steel profile, high strength advantage, is the best choice for fire walls.

Fire-resistant glass and steel curtain wall construction has an excellent effect and high economy. Aluminum (6063-T5) strength design value of 85.5MPa, the elastic modulus E = quadrillion MPa 0.7 × 10, and steel (Q235B) strength design value 215MPa, 2.5 times the aluminum alloy; elastic modulus E = 2. l × M Pa 10 quadrillion is 3.0 times that of aluminum, while hot-dip galvanized steel surface as a load-bearing structure, a smaller cross-sectional dimensions of the steel walls can form a larger sub-grid, increasing the glass curtain wall permeability; such architecture indoor obtain a broader perspective, more natural light and more effective use of space; better architectural effect; and a combination of a continuous cascade of overlapping seal drainage on all directions and with drainage channels to ensure that the walls of the water-tightness.
