鋼結構-----彩鋼板安裝

鋼結構(gou)中彩(cai)鋼板安裝：

1、屋(wu)面(mian)(mian)(mian)(mian)檁條(tiao)、墻(qiang)梁安(an)裝(zhuang)完畢，就可進行(xing)屋(wu)面(mian)(mian)(mian)(mian)、墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)的安(an)裝(zhuang)。一般是(shi)先安(an)裝(zhuang)墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)，后安(an)裝(zhuang)屋(wu)面(mian)(mian)(mian)(mian)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)，以(yi)便于(yu)檐(yan)口部(bu)位的連(lian)接(jie)(jie)(jie)。彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)安(an)裝(zhuang)有隱(yin)藏式連(lian)接(jie)(jie)(jie)和自攻螺(luo)絲(si)(si)連(lian)接(jie)(jie)(jie)兩種。隱(yin)藏式連(lian)接(jie)(jie)(jie)通過支架將(jiang)(jiang)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)固(gu)定在檁條(tiao)上(shang)，彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)橫向(xiang)之間用咬口機將(jiang)(jiang)相鄰(lin)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)搭接(jie)(jie)(jie)口咬接(jie)(jie)(jie)，或(huo)以(yi)防水(shui)粘(zhan)結膠(jiao)粘(zhan)接(jie)(jie)(jie)（這種做法僅適用于(yu)屋(wu)面(mian)(mian)(mian)(mian)）。自攻螺(luo)絲(si)(si)連(lian)接(jie)(jie)(jie)是(shi)將(jiang)(jiang)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)直接(jie)(jie)(jie)通過自攻螺(luo)絲(si)(si)固(gu)定在屋(wu)面(mian)(mian)(mian)(mian)檁條(tiao)或(huo)墻(qiang)梁上(shang)，在螺(luo)絲(si)(si)處涂防水(shui)膠(jiao)封口，這種方(fang)法可用于(yu)屋(wu)面(mian)(mian)(mian)(mian)或(huo)墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)連(lian)接(jie)(jie)(jie)。彩(cai)鋼(gang)板(ban)(ban)(ban)(ban)在縱(zong)向(xiang)需要(yao)接(jie)(jie)(jie)長時，其搭接(jie)(jie)(jie)長度(du)滿足設計要(yao)求，一般≥250mm，并(bing)用自攻螺(luo)絲(si)(si)連(lian)接(jie)(jie)(jie)，防水(shui)膠(jiao)封口。

2、天溝(gou)安(an)裝，內(nei)(nei)天溝(gou)多(duo)采用(yong)不銹(xiu)鋼制(zhi)品用(yong)不銹(xiu)鋼支撐(cheng)固定在檐(yan)口的邊(bian)梁（檁條）上，支撐(cheng)架的間距約500mm，用(yong)螺栓(shuan)連接。另外(wai)，內(nei)(nei)天溝(gou)也有采用(yong)2－3mm鋼板壓制(zhi)水槽的做法，而且在水槽內(nei)(nei)側(ce)涂(tu)上瀝青(qing)油防(fang)腐。外(wai)天溝(gou)多(duo)采用(yong)彩板制(zhi)品，用(yong)支撐(cheng)固定在檐(yan)口的屋面板上。

3、彩(cai)鋼(gang)板(ban)安裝中，應注意幾個關鍵部位的(de)(de)(de)構造做法：山墻(qiang)(qiang)(qiang)檐(yan)口處(chu)，用檐(yan)口包(bao)(bao)角(jiao)(jiao)板(ban)連接屋(wu)面(mian)和墻(qiang)(qiang)(qiang)面(mian)彩(cai)鋼(gang)板(ban)；屋(wu)脊蓋(gai)板(ban)，可根據屋(wu)面(mian)的(de)(de)(de)坡(po)(po)度大(da)(da)小(xiao)，分屋(wu)面(mian)坡(po)(po)度大(da)(da)于或等于10°和小(xiao)于10°兩種(zhong)不同的(de)(de)(de)做法；門(men)窗(chuang)(chuang)(chuang)位置，依窗(chuang)(chuang)(chuang)的(de)(de)(de)兩側設立窗(chuang)(chuang)(chuang)邊立柱，立柱與墻(qiang)(qiang)(qiang)梁連接固(gu)定，在窗(chuang)(chuang)(chuang)頂(ding)、窗(chuang)(chuang)(chuang) 臺處(chu)設墻(qiang)(qiang)(qiang)梁，安裝彩(cai)鋼(gang)板(ban)墻(qiang)(qiang)(qiang)面(mian)時，在窗(chuang)(chuang)(chuang)頂(ding)、窗(chuang)(chuang)(chuang)臺、窗(chuang)(chuang)(chuang)側分別用不同規(gui)格(ge)的(de)(de)(de)連接板(ban)包(bao)(bao)角(jiao)(jiao)處(chu)理；墻(qiang)(qiang)(qiang)面(mian)轉角(jiao)(jiao)處(chu)，用包(bao)(bao)角(jiao)(jiao)板(ban)連接外(wai)墻(qiang)(qiang)(qiang)轉角(jiao)(jiao)處(chu)的(de)(de)(de)接口彩(cai)鋼(gang)板(ban)。
