16、圍第7.6.2條的理解是把住宅排除在外的。高層商住樓消防設(shè)計(jì)的常規(guī)做法一般采用全樓設(shè)消火栓滅火系統(tǒng)，裙樓和地下室增設(shè)自動(dòng)噴水滅火系統(tǒng)。因此，噴淋泵的揚(yáng)程選擇是較低的，功率也較小。在實(shí)際工程中曾遇到這樣的例子：某幢28層的商住樓在消防驗(yàn)收時(shí)，公安消防部門要求住宅層的電梯和走道增加噴淋系統(tǒng)。為此業(yè)主不得不增加消防噴淋泵，在梯間安裝消防噴淋管道和噴頭。結(jié)果不但增加了工程造價(jià)，也影響了電梯廳的美觀及工程進(jìn)度?！　「鶕?jù)“高規(guī)”第七章第二節(jié)對(duì)消防

17、用水量的規(guī)定可知，一類高層住宅樓的室內(nèi)消火栓用水量為20 L/s，而一類高層商住樓的室內(nèi)消火栓用水量為40L/s，二者相差了一倍。以一幢30層 的住宅樓和一幢相同高度的商住樓（24m以下裙樓為商業(yè)用途，其上為住宅）為例，來分析一下它們的火災(zāi)危險(xiǎn)性。對(duì)于商住樓的裙樓，如作為商場(chǎng)、餐廳等用途時(shí)，由于其裝修豪華，</p><p>　　參考文獻(xiàn)：　　［1］ GB 50045—1995，高層民用建筑設(shè)計(jì)防火規(guī)范［S］.&
