鋼結構-----彩鋼板安裝

鋼(gang)結(jie)構中彩鋼(gang)板安(an)裝：

1、屋(wu)(wu)面檁條、墻梁安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)，就可進行屋(wu)(wu)面、墻面彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)的安(an)裝(zhuang)(zhuang)(zhuang)。一般是先(xian)安(an)裝(zhuang)(zhuang)(zhuang)墻面彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)，后安(an)裝(zhuang)(zhuang)(zhuang)屋(wu)(wu)面彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)，以便于檐口(kou)(kou)(kou)部位的連(lian)接(jie)(jie)。彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)安(an)裝(zhuang)(zhuang)(zhuang)有隱藏(zang)式(shi)連(lian)接(jie)(jie)和自(zi)攻(gong)(gong)螺絲(si)連(lian)接(jie)(jie)兩種。隱藏(zang)式(shi)連(lian)接(jie)(jie)通過支架將彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)固(gu)定(ding)在檁條上(shang)，彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)橫(heng)向之間用(yong)(yong)咬(yao)口(kou)(kou)(kou)機將相(xiang)鄰(lin)彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)搭(da)接(jie)(jie)口(kou)(kou)(kou)咬(yao)接(jie)(jie)，或(huo)以防水粘結膠粘接(jie)(jie)（這(zhe)種做法僅(jin)適用(yong)(yong)于屋(wu)(wu)面）。自(zi)攻(gong)(gong)螺絲(si)連(lian)接(jie)(jie)是將彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)直接(jie)(jie)通過自(zi)攻(gong)(gong)螺絲(si)固(gu)定(ding)在屋(wu)(wu)面檁條或(huo)墻梁上(shang)，在螺絲(si)處涂(tu)防水膠封口(kou)(kou)(kou)，這(zhe)種方法可用(yong)(yong)于屋(wu)(wu)面或(huo)墻面彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連(lian)接(jie)(jie)。彩(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)在縱向需要(yao)接(jie)(jie)長(chang)時(shi)，其搭(da)接(jie)(jie)長(chang)度滿足設計要(yao)求，一般≥250mm，并用(yong)(yong)自(zi)攻(gong)(gong)螺絲(si)連(lian)接(jie)(jie)，防水膠封口(kou)(kou)(kou)。

2、天溝(gou)安(an)裝，內(nei)(nei)天溝(gou)多采用(yong)不銹鋼(gang)制品(pin)(pin)用(yong)不銹鋼(gang)支撐(cheng)(cheng)(cheng)固(gu)定在檐(yan)口的邊梁（檁條）上(shang)，支撐(cheng)(cheng)(cheng)架的間距約500mm，用(yong)螺栓連接。另外，內(nei)(nei)天溝(gou)也有(you)采用(yong)2－3mm鋼(gang)板壓制水槽的做法(fa)，而且在水槽內(nei)(nei)側涂上(shang)瀝青油防腐。外天溝(gou)多采用(yong)彩板制品(pin)(pin)，用(yong)支撐(cheng)(cheng)(cheng)固(gu)定在檐(yan)口的屋面(mian)板上(shang)。

3、彩鋼(gang)板(ban)(ban)安裝中，應注意幾個關(guan)鍵部位(wei)的(de)(de)(de)構造做法(fa)：山墻(qiang)(qiang)檐口處，用檐口包(bao)角(jiao)(jiao)板(ban)(ban)連接(jie)屋(wu)面(mian)和墻(qiang)(qiang)面(mian)彩鋼(gang)板(ban)(ban)；屋(wu)脊蓋板(ban)(ban)，可根據屋(wu)面(mian)的(de)(de)(de)坡(po)度大小，分(fen)屋(wu)面(mian)坡(po)度大于(yu)或等于(yu)10°和小于(yu)10°兩種(zhong)不(bu)同(tong)的(de)(de)(de)做法(fa)；門窗位(wei)置，依窗的(de)(de)(de)兩側設(she)立(li)窗邊(bian)立(li)柱，立(li)柱與墻(qiang)(qiang)梁連接(jie)固定(ding)，在窗頂、窗 臺(tai)處設(she)墻(qiang)(qiang)梁，安裝彩鋼(gang)板(ban)(ban)墻(qiang)(qiang)面(mian)時，在窗頂、窗臺(tai)、窗側分(fen)別用不(bu)同(tong)規格的(de)(de)(de)連接(jie)板(ban)(ban)包(bao)角(jiao)(jiao)處理；墻(qiang)(qiang)面(mian)轉(zhuan)角(jiao)(jiao)處，用包(bao)角(jiao)(jiao)板(ban)(ban)連接(jie)外墻(qiang)(qiang)轉(zhuan)角(jiao)(jiao)處的(de)(de)(de)接(jie)口彩鋼(gang)板(ban)(ban)。
