鋼結構-----彩鋼板安裝

鋼(gang)結構(gou)中彩鋼(gang)板(ban)安裝：

1、屋面檁(lin)條(tiao)、墻(qiang)梁安(an)裝(zhuang)(zhuang)完畢，就可進行屋面、墻(qiang)面彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)的(de)安(an)裝(zhuang)(zhuang)。一(yi)般是先(xian)安(an)裝(zhuang)(zhuang)墻(qiang)面彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)，后安(an)裝(zhuang)(zhuang)屋面彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)，以便于(yu)檐(yan)口部位(wei)的(de)連接。彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)安(an)裝(zhuang)(zhuang)有隱(yin)藏(zang)(zang)式連接和(he)自攻螺(luo)絲連接兩(liang)種(zhong)。隱(yin)藏(zang)(zang)式連接通(tong)過(guo)支架將(jiang)彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)固(gu)定在檁(lin)條(tiao)上(shang)，彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)橫向(xiang)之間用咬口機(ji)將(jiang)相鄰彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)搭(da)接口咬接，或(huo)以防水粘結膠粘接（這種(zhong)做法僅適用于(yu)屋面）。自攻螺(luo)絲連接是將(jiang)彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)直接通(tong)過(guo)自攻螺(luo)絲固(gu)定在屋面檁(lin)條(tiao)或(huo)墻(qiang)梁上(shang)，在螺(luo)絲處涂防水膠封口，這種(zhong)方法可用于(yu)屋面或(huo)墻(qiang)面彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)連接。彩(cai)(cai)(cai)(cai)(cai)鋼板(ban)在縱向(xiang)需要接長(chang)時(shi)，其搭(da)接長(chang)度滿足設(she)計要求，一(yi)般≥250mm，并用自攻螺(luo)絲連接，防水膠封口。

2、天(tian)溝安裝，內(nei)天(tian)溝多采用(yong)(yong)(yong)(yong)不銹(xiu)鋼(gang)制品用(yong)(yong)(yong)(yong)不銹(xiu)鋼(gang)支(zhi)撐固(gu)定在(zai)檐口(kou)(kou)的邊(bian)梁（檁條）上(shang)，支(zhi)撐架的間距約500mm，用(yong)(yong)(yong)(yong)螺栓連接。另外，內(nei)天(tian)溝也有采用(yong)(yong)(yong)(yong)2－3mm鋼(gang)板壓制水槽的做法，而且在(zai)水槽內(nei)側涂上(shang)瀝青油防腐。外天(tian)溝多采用(yong)(yong)(yong)(yong)彩(cai)板制品，用(yong)(yong)(yong)(yong)支(zhi)撐固(gu)定在(zai)檐口(kou)(kou)的屋(wu)面(mian)板上(shang)。

3、彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)安(an)裝(zhuang)中，應(ying)注意幾個關鍵部(bu)位(wei)的(de)(de)構造做(zuo)法：山墻檐(yan)口(kou)處，用(yong)(yong)檐(yan)口(kou)包角(jiao)板(ban)(ban)連接(jie)屋(wu)面(mian)和(he)(he)墻面(mian)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)；屋(wu)脊蓋板(ban)(ban)，可根(gen)據屋(wu)面(mian)的(de)(de)坡度大小，分(fen)屋(wu)面(mian)坡度大于或等(deng)于10°和(he)(he)小于10°兩種不(bu)同的(de)(de)做(zuo)法；門窗(chuang)(chuang)(chuang)位(wei)置(zhi)，依窗(chuang)(chuang)(chuang)的(de)(de)兩側設立(li)窗(chuang)(chuang)(chuang)邊立(li)柱(zhu)，立(li)柱(zhu)與墻梁(liang)連接(jie)固定，在窗(chuang)(chuang)(chuang)頂(ding)、窗(chuang)(chuang)(chuang) 臺處設墻梁(liang)，安(an)裝(zhuang)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)墻面(mian)時(shi)，在窗(chuang)(chuang)(chuang)頂(ding)、窗(chuang)(chuang)(chuang)臺、窗(chuang)(chuang)(chuang)側分(fen)別用(yong)(yong)不(bu)同規格的(de)(de)連接(jie)板(ban)(ban)包角(jiao)處理；墻面(mian)轉角(jiao)處，用(yong)(yong)包角(jiao)板(ban)(ban)連接(jie)外(wai)墻轉角(jiao)處的(de)(de)接(jie)口(kou)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)。
