【正文】 xxxx 大學(xué)本科生畢業(yè)設(shè)計(jì) 某高層綜合樓防排煙設(shè)計(jì) 摘 要 本次設(shè)計(jì)的項(xiàng)目是某商住綜合樓，地下一層，地上十二層。其中地下一層為庫房和設(shè)備用房，一層為商場(chǎng)大廳及車庫，二～三層為商場(chǎng)，四～十層為辦公室、酒店套房及居民住房，十一層為居民住房，十二層為居民住房和設(shè)備用房。根據(jù)平面布置圖完成防排煙系統(tǒng)及加壓送風(fēng)系統(tǒng)的設(shè)計(jì)。根據(jù)建筑的功能和結(jié)構(gòu)要求，將其劃分成不同的防火和防煙分區(qū)，分別對(duì)各個(gè)防煙分區(qū)、前室、合用前室及樓梯間的排煙和加壓送風(fēng)系統(tǒng)進(jìn)行布置、設(shè)計(jì)并設(shè)置排煙口和加壓送風(fēng)口。選擇合適的機(jī)械防排煙和加壓送風(fēng)方式，并進(jìn)行管網(wǎng)的布置、計(jì)算、校核 以及風(fēng)機(jī)的選型。 關(guān)鍵詞 ：防排煙 加壓送風(fēng) 系統(tǒng)設(shè)計(jì) 排煙口 送風(fēng)口 The smoke management systems of a multipleuse building ABSTRACT The project designed is a multipleuse building with one floor under the ground and 12 floors on the ground. The underground floor is treasuries and the equipment room. The first floor on the ground is the shopping hall and garage, the second to third floor on the ground are malls, the forth floor to tenth floors are offices, hotel suites and residential housing, the eleventh floor is housing for the residents, the twelfth floor is residential housing and equipment rooms. In the thesis the Smoke Management Systems and the Pressurized air supply Systems were designed. According to the functional and structural requirements of the building， The building was divided into diffent firezones and smokezones. The venting system and the pressuried air supply system are designed for the building. Key Words： Smoke Management。 Pressurized air supply。 design of systems。 exhaust port。 supply outlet xxxx 大學(xué)本科生畢業(yè)設(shè)計(jì) 目 錄 第 1 章 概述 ................................................................................................................................. 1 設(shè)計(jì)項(xiàng)目 .......................................................................................................................... 1 設(shè)計(jì)內(nèi)容 .......................................................................................................................... 1 第 2 章 防排煙概述 ..................................................................................................................... 2 火災(zāi)煙氣 .......................................................................................................................... 2 煙氣 的組成 ........................................................................................................... 2 燃燒產(chǎn)物的分類 ................................................................................................... 2 火災(zāi)煙氣的危害性 ............................................................................................... 2 防排煙區(qū)域的劃分 .......................................................................................................... 3 防排煙方式 ...................................................................................................................... 4 防煙方式 ............................................................................................................... 4 擋煙設(shè)施 ............................................................................................................... 5 排煙方式 ............................................................................................................... 5 防排煙設(shè)備 ...................................................................................................................... 6 排煙口 ................................................................................................................... 6 正壓送風(fēng)口 ........................................................................................................... 7 排煙風(fēng)道 ............................................................................................................... 8 防火閥 ................................................................................................................... 9 風(fēng)機(jī) ....................................................................................................................... 9 第 3 章 高層建筑防排煙系統(tǒng)設(shè)計(jì) ........................................................................................... 11 設(shè)計(jì)步驟 ........................................................................................................................ 11 設(shè)計(jì)任務(wù) ........................................................................................................................ 11 高層建筑防排煙系統(tǒng)概述 ............................................................................................. 11 高層建筑防火排煙基本概念 ............................................................................. 12 高層建筑的防火分區(qū)和防煙分區(qū) ..................................................................... 12 防排煙方式的選擇 ......................................................................................................... 12 第 4 章 管路水力計(jì)算 ............................................................................................................... 14 防煙分區(qū)的劃分 ............................................................................................................ 14 排煙系統(tǒng)的布置 ............................................................................................................ 21 管道水力計(jì)算 ................................................................................................................ 22 風(fēng)機(jī)及配套電動(dòng)機(jī)的選擇 ............................................................................................ 30 風(fēng)量、風(fēng)壓、電動(dòng)機(jī)功率的計(jì)算 ..................................................................... 31 風(fēng)機(jī)及其配套電動(dòng)機(jī)的選型 ............................................................................. 32 第 5 章 正壓送風(fēng)的布置及計(jì)算 ............................................................................................... 33 概述 ................................................................................................................................ 33 加壓送風(fēng)防煙設(shè)施設(shè)置部位 ........................................................................................ 33 加壓送風(fēng)量的確定 ........................................................................................................ 33 正壓送風(fēng)系統(tǒng)的設(shè)置 ..............................................................
