建築防火是設計施工上的一個重點,首先要保證安全,然後才能更多的建築裝飾。現在的大型場館,建築基本上都是采用防火玻璃幕牆和防火隔斷組成,作為防火玻璃隔斷,根據建築物火災蔓延的方式,其應有如下基本特性:

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)隔煙:在火災發生時,能阻擋火災產生的煙氣從受火的一麵傳到背火的一麵。這是比較基本的要求,合理有效地阻擋是火災產生的煙氣,避免形成煙囪效應,是控製火勢蔓延,保證疏散通道暢通或避難有效的根本。

(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:在火災發生時,其一麵受火時,能在一定時間內防止火焰穿透或防止火焰在背火麵出現。根據建築防火的設計要求,防火隔斷應具有良好的完整性。如出現一燒即倒,一燒即垮或達不到防火時限的要求,火災也會蔓延,起不到減少火災損失的目的。

(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)耐火隔熱性:在火災發生,其一麵受火時,能在一定時間內其背火麵溫度上升不至於引燃背火區物品。如滿足了隔煙,保證了完整,但由於火災產生的熱量通過防火玻璃後大量的熱輻射導致背火麵的易燃物燃燒,也沒有起到防火的作用。

(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.
