避难间防火门

F8 · 2 门型

避难间防火门是"让人在里面等"与"等的那场火"之间的最后一道界。它必须按整樘成套指定而不是单扇门:要求覆盖整套构造——门框、门扇、密封、闭门器,很多设计还要承担挡烟功能。避难层、无障碍避难区与临时等待空间还要让行动不便的人能用,因此开启力与五金的人机工效和耐火等级同样重要。整套供货并附报审资料,确保到场的门与消防顾问签字确认的一致。

选型要点

  • 与无障碍顾问确认开启力要求:耐火等级达标,人机工效仍可能不合格。
  • 确定这套门是否承担挡烟功能,因为它会改变密封与五金配置。
  • 把整樘作为一个条目报审:门扇、门框、密封与闭门器同列。
  • 把标识与导向纳入配套,让避难路线在应急照明下清晰可读。

常见问题

What is included in a refuge door set?
Leaf, frame, intumescent and smoke seals, closer, and the hardware required by the design. It is quoted as one item so nothing is missed.
Does it need to be self-closing?
Refuge doors are normally self-closing and often tied to the alarm. The exact logic follows the fire strategy.
Can it be a double leaf?
Yes, where the opening width requires it. Double leaf sets need a coordinator so the leaves close in the right order.
Is documentation supplied for approval?
Yes. Drawings and the certificate references for the ordered configuration are provided for the approval process.
