建筑防火是设计施工上的一个重点,首先要保证安全,然后才能更多的建筑装饰。现在的大型场馆,建筑基本上都是采用防火玻璃幕墙和防火隔断组成,作为防火玻璃隔断,根据建筑物火灾蔓延的方式,其应有如下基本特性:

Building fire protection is a key point in design and construction. First, we must ensure safety, and then more buildings can be decorated. Today's large stadiums and stadiums are basically a fireproof glass curtain wall and a fireproof partition. As a fireproof glass partition, it should have the following basic characteristics according to the way of building fire spread.

(1)隔烟:在火灾发生时,能阻挡火灾产生的烟气从受火的一面传到背火的一面。这是比较基本的要求,合理有效地阻挡是火灾产生的烟气,避免形成烟囱效应,是控制火势蔓延,保证疏散通道畅通或避难有效的根本。

(1) smoke separation: when a fire occurs, it can block the smoke generated by the fire from the side of fire to the side of the back fire. It is the basic requirement to prevent the smoke from the fire reasonably and effectively, to avoid the chimney effect, to control the spread of the fire, to ensure the smooth passage of the evacuation passages or to avoid the effectiveness of the refuge.

(2)耐火完整性:在火灾发生时,其一面受火时,能在一定时间内防止火焰穿透或防止火焰在背火面出现。根据建筑防火的设计要求,防火隔断应具有良好的完整性。如出现一烧即倒,一烧即垮或达不到防火时限的要求,火灾也会蔓延,起不到减少火灾损失的目的。

(2) integrity of fire: when a fire occurs, when one side is exposed to fire, it can prevent flames from penetrating or prevent flames from appearing on the back fire surface for a certain time. According to the design requirements of building fire protection, fire isolation should have good integrity. If a fire occurs, or if a fire fails or fails to meet the requirements of the time limit for fire protection, the fire will also spread, and there will be no way to reduce the loss of fire.

(3)耐火隔热性:在火灾发生,其一面受火时,能在一定时间内其背火面温度上升不至于引燃背火区物品。如满足了隔烟,保证了完整,但由于火灾产生的热量通过防火玻璃后大量的热辐射导致背火面的易燃物燃烧,也没有起到防火的作用。

(3) fire resistance and heat insulation: when the fire is on the side of fire, it will increase the temperature of the back fire surface within a certain time, and it will not ignite the goods in the back fire area. If the smoke is satisfied, it ensures the integrity, but the fire caused by the heat of fire through the fire glass after a large amount of heat radiation causes flammable flammability of the back fire, and does not play the role of fire protection.
