关于《高层民用建筑设计防火规范》防排烟条款的修改意见
Modification suggestion about the items of smoke control and extraction in the Code for fire protection design of tall buildings
摘要：
随着建筑规模的增大、建筑层数和建筑功能的增多，以及防排烟理论的发展，认为以往对规范头疼医头式的局部修订做法先天不足，需要全面修订。对规范的自然排烟、机械排烟及其设置、机械防烟条款提出了修改意见，供规范讨论和修订时参考。

Puts forward some amending suggestions for the items of natural exhaust smoke, the mechanical exhaust smoke and the extractor, and the mechanical fire control in the criterion for further reference and discussion.
