管井防火门

F9 · 2 门型

管井防火门是服务核心筒上那些尺寸小、使用频次高的检修门。它们封闭水管井、电气井、表箱与风管井,因为物业每周都要进出,开启频率远高于普通走廊门。所以真正的工程问题不是尺寸而是耐久:门扇下垂、锁舌咬不上、闭门器失去调节,都会让一个本来合规的管井变成防火分区上的一个洞。整樘以钢质制作,覆盖小规格单扇与双扇,闭合与锁闭五金按频繁检修的工况选型。

选型要点

  • 五金按频繁检修选型,不要照搬走廊门的工况。
  • 门扇控制在一个人拿着工具也能操作的重量。
  • 确认管井墙体构造:砌体井与轻钢龙骨井的门框固定方式不同。
  • 门上标注所服务的管井编号;在繁忙楼层,标错门是真实的运维问题。

Access control depends on the building's security regime; it is specified with the door so the hardware is compatible.
