摘要
结合现场的实际情况,介绍了在哪些场所敷设的电缆应采取防火封堵措施;国内常用的三种电缆防火封堵的材料;各种环境下(包括电气室盘柜底部、电缆桥架穿墙洞、电缆桥架穿防火门、电缆竖井内电缆桥架穿楼板孔洞、电缆保护管穿楼板、电缆穿越建筑物的外墙处)的电缆封堵设计。提出了设计和施工过程中切实可行的措施。
Incorporated with the actual situation on-site, that the fire proof clogging measures should be taken for cables laid in what kind of locations and 3 kinds of fire proof clogging materials for cables are introduced. Moreover the cable fire proof clogging design for various environments have been explained, including: for the bottom of cabinet box in the electrical room; the through-opening holes of wall for cable bridge tray; cable bridge tray passing through the fire-proof door; floor through-holes for cable bridge tray in the cable silo, floor through-holes for cable protection pipes; at the external wall for cables to pass through the building. And the feasible measures for design and construction process have been put forward.
