Firestop

产品概念(Product Concept)

防火封堵系统,阻火或防火,一种被动防火形式。用于密封防火等级的墙壁或地板组件中的开口周围和接缝之间。

防火封堵指对防火建筑之间的缝隙进行四周封闭,如墙体与上面楼层之间的线形缝隙,使建筑形成一个完整的屏障,阻止火灾和烟雾的蔓延。 

用于密封防火等级的墙壁或地板组件中的开口周围和接缝之间。

Firestop or fireproofing is a form of passive fire protection. It is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. 

Fire stopping is to seal around gaps between fire resisting constructions, e.g. the linear gap between a wall and the floor above, in order for construction to form a complete barrier to fire and smoke spread.


开口类型(Opening Types)

阻火材料用于 Firestops are used in:


电气、机械和结构穿透

Electrical, mechanical, and structural penetrations


未穿透的开口(例如供将来使用的开口)

Unpenetrated openings (such as openings for future use)


重新进入现有的防火板

Re-entries of existing firestops


在防火等级的墙壁或地板组件中控制或摆动接头

Control or sway joints in fire-resistance-rated wall or floor assemblies


防火等级的墙壁或地板组件之间的连接

Junctions between fire-resistance-rated wall or floor assemblies


墙头(HOW) 接头,非承重墙组件与地板组件相遇的地方

Head-of-wall (HOW) joints, where non-load-bearing wall assemblies meet floor assemblies


数字字符用于识别在本系统中可以找到什么渗透剂(如果有的话),并帮助识别所使用的 UL 测试系统。

Numeric characters are used to identify what penetrant, if any, can be found within the present system and help identify what UL-tested system was used.


穿透分类及其穿透的屏障,按照所有防火产品制造商采用的标准化字母数字系统进行分类。 一个典型的系统由几个字母组成,后跟一系列数字,表示通过特定屏障的渗透剂类型,例如:(FB-5533。)

Classification for penetrations and the barriers they penetrate, are categorized by a standardized letter-number system that has been adopted by all firestop products manufacturers. A typical system would consist of several letters, followed by a series of numbers indicating the type of penetrant that is passing through the particular barrier ex: (FB-5533.)
