鋼結構-----彩鋼板安裝

鋼(gang)結構中彩(cai)鋼(gang)板安(an)裝(zhuang)：

1、屋(wu)面(mian)(mian)(mian)(mian)檁(lin)條(tiao)(tiao)、墻(qiang)梁安(an)(an)裝(zhuang)完畢(bi)，就可(ke)(ke)進行屋(wu)面(mian)(mian)(mian)(mian)、墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)(cai)鋼板(ban)(ban)的安(an)(an)裝(zhuang)。一(yi)般(ban)是(shi)先安(an)(an)裝(zhuang)墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)(cai)鋼板(ban)(ban)，后安(an)(an)裝(zhuang)屋(wu)面(mian)(mian)(mian)(mian)彩(cai)(cai)鋼板(ban)(ban)，以便于(yu)檐(yan)口(kou)部位(wei)的連(lian)(lian)(lian)接。彩(cai)(cai)鋼板(ban)(ban)安(an)(an)裝(zhuang)有隱藏式連(lian)(lian)(lian)接和自(zi)攻螺(luo)絲(si)(si)連(lian)(lian)(lian)接兩種(zhong)。隱藏式連(lian)(lian)(lian)接通(tong)過(guo)支架將彩(cai)(cai)鋼板(ban)(ban)固定(ding)在(zai)(zai)檁(lin)條(tiao)(tiao)上，彩(cai)(cai)鋼板(ban)(ban)橫向(xiang)之間用咬(yao)(yao)口(kou)機將相鄰(lin)彩(cai)(cai)鋼板(ban)(ban)搭(da)接口(kou)咬(yao)(yao)接，或(huo)以防水(shui)粘結膠粘接（這種(zhong)做法僅適用于(yu)屋(wu)面(mian)(mian)(mian)(mian)）。自(zi)攻螺(luo)絲(si)(si)連(lian)(lian)(lian)接是(shi)將彩(cai)(cai)鋼板(ban)(ban)直接通(tong)過(guo)自(zi)攻螺(luo)絲(si)(si)固定(ding)在(zai)(zai)屋(wu)面(mian)(mian)(mian)(mian)檁(lin)條(tiao)(tiao)或(huo)墻(qiang)梁上，在(zai)(zai)螺(luo)絲(si)(si)處涂(tu)防水(shui)膠封(feng)口(kou)，這種(zhong)方法可(ke)(ke)用于(yu)屋(wu)面(mian)(mian)(mian)(mian)或(huo)墻(qiang)面(mian)(mian)(mian)(mian)彩(cai)(cai)鋼板(ban)(ban)連(lian)(lian)(lian)接。彩(cai)(cai)鋼板(ban)(ban)在(zai)(zai)縱(zong)向(xiang)需(xu)要(yao)(yao)接長(chang)時，其搭(da)接長(chang)度滿足設計(ji)要(yao)(yao)求，一(yi)般(ban)≥250mm，并用自(zi)攻螺(luo)絲(si)(si)連(lian)(lian)(lian)接，防水(shui)膠封(feng)口(kou)。

2、天溝(gou)(gou)(gou)安裝，內(nei)天溝(gou)(gou)(gou)多采(cai)用(yong)(yong)不銹鋼(gang)(gang)制(zhi)品用(yong)(yong)不銹鋼(gang)(gang)支(zhi)撐固定(ding)在檐口(kou)的(de)邊梁（檁(lin)條）上(shang)，支(zhi)撐架的(de)間距約500mm，用(yong)(yong)螺栓連接。另外(wai)，內(nei)天溝(gou)(gou)(gou)也有采(cai)用(yong)(yong)2－3mm鋼(gang)(gang)板(ban)壓(ya)制(zhi)水(shui)槽的(de)做法，而且(qie)在水(shui)槽內(nei)側涂(tu)上(shang)瀝青油(you)防腐(fu)。外(wai)天溝(gou)(gou)(gou)多采(cai)用(yong)(yong)彩板(ban)制(zhi)品，用(yong)(yong)支(zhi)撐固定(ding)在檐口(kou)的(de)屋面板(ban)上(shang)。

3、彩鋼板(ban)(ban)安(an)裝(zhuang)中，應注意(yi)幾個關鍵部(bu)位的(de)構(gou)造做法：山墻檐(yan)口處(chu)(chu)，用(yong)(yong)檐(yan)口包角(jiao)(jiao)(jiao)板(ban)(ban)連(lian)接(jie)(jie)(jie)屋面(mian)和(he)墻面(mian)彩鋼板(ban)(ban)；屋脊(ji)蓋(gai)板(ban)(ban)，可根據屋面(mian)的(de)坡(po)度大小(xiao)，分(fen)屋面(mian)坡(po)度大于或等于10°和(he)小(xiao)于10°兩(liang)種不同的(de)做法；門窗(chuang)(chuang)(chuang)位置，依窗(chuang)(chuang)(chuang)的(de)兩(liang)側(ce)設立(li)窗(chuang)(chuang)(chuang)邊(bian)立(li)柱(zhu)，立(li)柱(zhu)與墻梁連(lian)接(jie)(jie)(jie)固定，在(zai)窗(chuang)(chuang)(chuang)頂、窗(chuang)(chuang)(chuang) 臺處(chu)(chu)設墻梁，安(an)裝(zhuang)彩鋼板(ban)(ban)墻面(mian)時，在(zai)窗(chuang)(chuang)(chuang)頂、窗(chuang)(chuang)(chuang)臺、窗(chuang)(chuang)(chuang)側(ce)分(fen)別用(yong)(yong)不同規格的(de)連(lian)接(jie)(jie)(jie)板(ban)(ban)包角(jiao)(jiao)(jiao)處(chu)(chu)理；墻面(mian)轉角(jiao)(jiao)(jiao)處(chu)(chu)，用(yong)(yong)包角(jiao)(jiao)(jiao)板(ban)(ban)連(lian)接(jie)(jie)(jie)外墻轉角(jiao)(jiao)(jiao)處(chu)(chu)的(de)接(jie)(jie)(jie)口彩鋼板(ban)(ban)。
