如何发挥防火玻璃隔断的作用

  如何发挥防火玻璃隔断的作用

  

  防火玻璃隔断由单层玻璃组成,多用于大型公共建筑、防火划分、室外幕墙等建筑部位。防火玻璃隔断经过长时间的高温离子交换化学处理过程,具有低热膨胀率的优点,在一段时间内可以保持高温下玻璃软化而不破碎,通过保持玻璃的完整性阻挡迎火面的明火、有毒有害气体等,但不能隔温绝热。接下来小编为大家介绍什么是防火玻璃隔断及防火玻璃隔断特点。

  

  大家都知道防火玻璃隔断有很好的隔热、防火性能等特点,在火灾来临时能很好的保护人员、财产及建筑物,大大减少损失,深受消费者的青睐,还广泛运用于计算机房,高精实验室,学校,党政机关核心部分。

  

  一、明确防火玻璃和防火玻璃隔断是不同的消防产品

  防火玻璃是一种建筑原材料,不能作为建筑构件在建筑工程中使用,而防火玻璃隔断为整体框架系统。因此乌鲁是业主、设计人员,还是施工、监理人员都应明确防火玻璃和防火玻璃隔断是完全不同的消防产品,并在实际应用中学会查看对应产品的型式检验报告。

  

  二、明确防火玻璃隔断的使用范围和设计应用原则

  防火玻璃、防火门、防火窗、将防火玻璃隔断纳入其中的镶玻璃构件耐火试验方法等标准均已提出了隔热、非隔热的概念,但是消防设计规范至今没有做相应的调整。根据现行消防设计规范,目前市场上的非隔热型耐火构件不能使用。

  

  三、合理选型和规范施工

  防火玻璃隔断耐火极限取决于所采用的防火玻璃、框架结构及玻璃与框架的连接固定方式,不同防火玻璃隔断的安装要求不同,如隔热型框架系统因为使用的是符合隔热型防火玻璃,受热时玻璃内胶体会发泡膨胀,所以在安装过程中玻璃与框架之间要留一定的空隙。

  

  四、假期nag消防产品现场一致性检查

  建筑工程的采购、施工、监理人员应明确防火玻璃、防火玻璃隔断、防火门、防火窗是完全不同的消防产品。采购人员应根据设计文件采购相应的消防产品,采购时应查验所需产品是否持有有效的由国家质量监督检验中心出具的检验报告及出厂检验合格证,且规格型号应与设计要求一致。

  

  防火玻璃隔断特点

  

  1、隔烟

  在火灾发生时,能有效防止火灾产生的烟气。这是最基本的要求,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。

  

  2、耐火完整性

  在发生火灾的时候,能在一定的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。

  

  3、耐火隔热性

  防火玻璃隔断能耐火隔热,能在有限的时间内背火面温度上升不至于燃烧背火区物品。可以满足隔烟,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。
