Description

Explosion-proof sealed fireproof window

Technical Field

The utility model relates to a building protection window technical field, in particular to explosion-proof sealed fire window.

Background

With the advance of the urbanization process of China, the number and the scale of towns are rapidly enlarged, high-rise buildings are gradually increased, and the buildings are more and more dense. With the increasing use of electricity, fire and other equipment and processes with fire hazard in production and life, the fire hazard is increased correspondingly, especially in densely populated places such as residential districts, shopping malls or commercial office buildings, once a fire occurs in one room, the fire easily spreads to adjacent rooms or even the whole building, and serious property loss and even casualties are caused. The fire window is one of important means for building fire prevention, and is widely applied to openings of fire walls, entrance and exit of stairways, dispersion passages, outer walls of buildings and the like of fire partitions of buildings to prevent fire from rapidly spreading to a wider area when a fire occurs.

The existing fireproof window generally adopts a steel frame or an aluminum alloy frame, and fireproof glass is embedded in the steel frame or the aluminum alloy frame so as to achieve the fireproof purpose. The steel fireproof window is not corrosion-resistant, and the sound insulation effect is poor, and the aluminum alloy fireproof window is light in weight, corrosion-resistant and high in strength, so that the market acceptance of the aluminum alloy fireproof window is high. But the melting point of aluminum alloy is lower, and when the conflagration took place, the scene of a fire temperature can reach more than 500 ℃ in the short time, and the aluminum alloy fire prevention window frame at this moment has softened, can't support fire prevention glass, and once fire prevention glass shifted and appears the gap, fire prevention window loses the fire prevention function promptly. In addition, a small explosion may accompany a fire, and if the fire window cannot resist the shock wave generated by the explosion, the overall structure is damaged or destroyed, and the fire-proof performance is correspondingly reduced or lost.
