In be widely used.With continuing to develop for China's economy, glass curtain wall application under construction is also more and more.
At the beginning of eighties of last century, people start to use double-layered glass facade in some are built.During double-layered glass facade is added by layer glass
Between air layer and solar protection devices composition.The glass curtain wall that the air layer between layer glass is aerated can be utilized to be referred to as breathing
Curtain wall.This curtain wall can obtain a large amount of sunshines, there is provided good gravity-flow ventilation, and energy energy saving, and for indoor offer is relaxed
Suitable environment.Because the unique construction of curtain wall, breathing-type glass curtain wall improve efficiently many problems of conventional curtain wall presence,
But just because of this kind of double-decker, new test is proposed in terms of fire safety problem to fire-fighting work person again.
Due to there is narrow space at interlayer in breathing-type glass curtain wall, when fire occurs, it is perpendicular that fire smoke flows
To the glass curtain wall of distance, particularly skyscraper, this hot stack effect is more significantly.In addition, bound on curtain wall and under
Back cover will leave certain gap with agent structure, the deformation of building body during absorbing sedimentation, flexible and earthquake.These deformations
Gap, expansion joint are also likely to be the approach of fire-propagation.Therefore, compared with common building beyond the region of objective existence wall, building breathing curtain wall support
And the fire resistance of glass is not high, when there is fire, if do not taken certain measure, flame and flue gas can be caused to be ruptured along curtain wall
Hole or the gap of the connecting portion such as curtain wall and floor, partition wall spread to contiguous floors or fire compartment, form three-dimensional fire,
Easily jeopardize the safety of whole building thing.
The main promising Plastic of the material therefor of " flame screen " so-called on existing market and wire netting class flame screen.It is domestic
In the market is most " flame screen ", the network structure that substantially flame retardant plastics is made.This kind of flame retardant plastics softening temperature one
