Want to know about fireproof glass curtain wall?Then Jingwan professional glass curtain wall manufacturers to tell you.
Glass curtain wall has obvious advantages in exterior wall decoration and can reduce the structural load of the building.At the same time, the glass curtain wall combines architecture and aesthetic structure design, which perfectly reflects the various functions of glass.Such as glass curtain wall permeability, through the glass line of sight to reach the best, the field of vision to reach the maximum, so that the building inside and outside the environment is interlinked, integration, so that the building facade more aesthetic feeling.
The country is more and more strict with building fire protection requirements, now a large number of fireproof glass instead of ordinary building glass and used in the glass curtain wall, that is, we now say that the fireproof glass curtain wall.The so-called fireproof glass curtain wall is composed of fireproof glass, fireproof steel frame, fireproof hardware and fireproof sealing materials, which can effectively control the time when building fire spreads to adjacent areas, and the fireproof time is not lower than the requirements of fire codes.
Requirements for fireproof glass curtain wall:
1. The smoke.In the event of a fire, the smoke generated by the fire can be prevented from spreading from the fire side to the back fire side.This is the most basic requirement, reasonably and effectively block the smoke produced by the fire, avoid the formation of chimney effect, effectively control the spread of the fire, ensure the safety of evacuation passage and refuge.
2. Fire-resistant integrity.In the event of a fire, when the fire is on one side, the flame can be prevented from penetrating or from appearing on the back fire surface for a certain period of time.According to the design requirements of building fire protection, fireproof glass curtain wall should have good integrity.If there is a burn or fail to meet the requirements of the fire protection time limit, the fire will spread, not to reduce the purpose of fire loss.
3. Fire resistance and heat insulation.In the event of a fire, when one side is exposed to fire, the temperature of the back fire surface can rise within a certain period of time so as not to ignite the goods in the cargo storage area.If the smoke isolation is satisfied, the integrity is guaranteed, but due to the heat generated by the fire through the fireproof glass after a large number of thermal radiation resulting in the back fire surface of the combustible combustion, also did not play the role of fire prevention.
According to the national standard of fireproof glass GB15763.1-2009, fireproof glass is divided into two categories:
A and C according to the fireproof performance.
Class A fireproof glass: fireproof glass that meets the requirements of fire integrity and fire insulation at the same time.
Class C fireproof glass: fireproof glass that meets the requirements of fireproof integrity.
According to the structure of fireproof glass is divided into single fireproof glass and composite fireproof glass:
Monolithic fireproof glass is made of single layer glass, and can meet the corresponding fire resistance requirements of the grade of special glass.
Composite transparent fireproof glass is made of two or more layers of glass or by a layer of glass and organic materials, and meet the corresponding fire resistance requirements of the grade of special glass.
The above is a brief introduction of fireproof glass curtain wall, I hope to help you, we are from China's professional glass curtain wall manufacturers - Jingwan Engineering, welcome to consult!
