泄爆墻的(de)(de)主要作用是防止爆(bao)用于泄(xie)(xie)爆(bao)的(de)(de)墻(qiang)，這樣能(neng)減少事故(gu)發生的(de)(de)可能(neng)性(xing)，就是當室內壓力達到一定(ding)值時，壓力通(tong)過(guo)泄(xie)(xie)爆(bao)墻(qiang)泄(xie)(xie)散(san)出去，材質不一樣泄(xie)(xie)散(san)的(de)(de)方(fang)法就會不同(tong)。泄(xie)(xie)爆(bao)墻(qiang)分為(wei)輕(qing)質易碎泄(xie)(xie)爆(bao)墻(qiang)和輕(qing)質泄(xie)(xie)爆(bao)墻(qiang)兩種(zhong)。
輕質(zhi)易碎泄(xie)爆(bao)墻和輕質(zhi)泄(xie)爆(bao)墻的安(an)裝方(fang)法：
1定位放線：在工(gong)程方案(an)設計中，泄(xie)爆墻(qiang)(qiang)板將充分考慮外墻(qiang)(qiang)風(feng)壓要求和墻(qiang)(qiang)體高度(du)等因素，制作和安裝檀香(xiang)（檁條）條。防爆減(jian)壓屋面清潔(jie)后，由專門廠(chang)家進行(xing)表面施(shi)工(gong)。
2.泄爆板龍骨安裝：方管在(zai)已完(wan)成的屋頂檁條上焊接并保持水(shui)平，方管間搭接采(cai)用全焊。
3.減壓板(ban)安(an)裝(zhuang):防(fang)爆減壓板(ban)規格(ge)240x1220x9mm，防(fang)爆減壓屋面雙層板(ban)結構。層板(ban)與(yu)(yu)龍骨連接后，第(di)二層板(ban)與(yu)(yu)層板(ban)錯(cuo)縫，用自(zi)攻螺(luo)釘(ding)與(yu)(yu)方管連接。自(zi)攻螺(luo)釘(ding)間(jian)距(ju)為:板(ban)邊間(jian)距(ju)200mm，板(ban)中間(jian)距(ju)300mm。
巖棉雙面泄爆墻與梁柱的(de)(de)連(lian)接節(jie)點(dian)采用M3.5自攻(gong)螺釘(ding)固定間距(ju)250mm。雙面泄爆(bao)墻(qiang)與外(wai)墻(qiang)梁柱的(de)(de)平連(lian)接節(jie)點(dian)采用M3.5自攻(gong)螺釘(ding)@250mm。M3.5自攻(gong)螺釘(ding)固定間距(ju)250mm。
室(shi)內側(ce)泄壓(ya)(ya)板(ban)采(cai)用單層(ceng)(ceng)2440*120*9纖維(wei)增(zeng)強水泥泄壓(ya)(ya)板(ban)，M2.5自(zi)攻(gong)鎖尾(wei)螺釘固(gu)定(ding)(ding)(ding)在龍骨(gu)上，固(gu)定(ding)(ding)(ding)間距250mm，固(gu)定(ding)(ding)(ding)在板(ban)與龍骨(gu)的(de)接(jie)縫處。室(shi)外側(ce)泄壓(ya)(ya)板(ban)采(cai)用雙(shuang)層(ceng)(ceng)2440*120*9纖維(wei)增(zeng)強水泥泄壓(ya)(ya)板(ban)，錯縫敷設，M3.5自(zi)攻(gong)鎖尾(wei)螺釘與龍骨(gu)固(gu)定(ding)(ding)(ding)間距250mm。
輕質泄(xie)壓墻(qiang)由(you)(you)雙(shuang)面纖維(wei)增(zeng)強(qiang)水泥減壓板(ban)(ban)(ban)和鍍鋅輕鋼龍骨系統(tong)填充巖棉組成(cheng)。室內單(dan)層纖維(wei)增(zeng)強(qiang)水泥板(ban)(ban)(ban)厚度(du)為9mm，室外雙(shuang)層纖維(wei)增(zeng)強(qiang)水泥板(ban)(ban)(ban)厚度(du)為18mm。鍍鋅輕鋼龍骨系統(tong)由(you)(you)水平龍骨和垂直(zhi)龍骨組成(cheng)。兩層纖維(wei)增(zeng)強(qiang)水泥減壓板(ban)(ban)(ban)中間填充85kg/m3巖棉，均勻布置在減壓墻(qiang)內。
