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。 With the increase of building scale, the increase of building layers and building functions, and the development of smoke control theory, we think that the past practice of local revision of the norm headache is not enough and needs to be fully revised. On the specification of natural smoke exhaust, mechanical exhaust and its settings, mechanical smoke terms proposed amendments, for discussion and revision of the normative reference.
