為了保證(zheng)鋁塑(su)板(ban)(ban)安(an)裝(zhuang)(zhuang)完(wan)(wan)畢(bi)后分(fen)格水(shui)平(ping)縫一條線(xian)和分(fen)格垂直縫的垂直度,在外墻(qiang)實體放線(xian)時(shi),必須要(yao)精(jing)確到允(yun)許誤差范圍(wei)內。龍骨(gu)焊(han)接處(chu)的防(fang)腐是(shi)一項非常(chang)重要(yao)工序,焊(han)接厚度不小(xiao)于5mm,這項指標涉(she)及到鋁塑(su)板(ban)(ban)幕(mu)墻(qiang)整體使(shi)用壽(shou)命的周期。龍骨(gu)在組裝(zhuang)(zhuang)完(wan)(wan)畢(bi)后,及時(shi)在焊(han)縫處(chu)刷防(fang)腐漆兩(liang)遍(bian),當外墻(qiang)龍骨(gu)安(an)裝(zhuang)(zhuang)完(wan)(wan)畢(bi)時(shi)再檢查一遍(bian),是(shi)否有(you)漏刷防(fang)腐漆處(chu)。
外墻與(yu)(yu)龍(long)(long)(long)骨(gu)(gu)的(de)(de)連(lian)接(jie)是靠外墻上(shang)安裝的(de)(de)膨脹(zhang)螺(luo)栓(shuan)連(lian)接(jie),因此鋁(lv)塑板幕墻整體的(de)(de)牢(lao)固性就取決于(yu)外墻膨脹(zhang)螺(luo)栓(shuan)的(de)(de)抗拉強度(du)(du),膨脹(zhang)螺(luo)栓(shuan)的(de)(de)抗拉強度(du)(du)。龍(long)(long)(long)骨(gu)(gu)與(yu)(yu)膨脹(zhang)螺(luo)栓(shuan)的(de)(de)連(lian)接(jie)采用角(jiao)(jiao)碼(ma)連(lian)接(jie),角(jiao)(jiao)碼(ma)型號根據龍(long)(long)(long)骨(gu)(gu)大(da)小(xiao)而定,當龍(long)(long)(long)骨(gu)(gu)沿墻壁(bi)送到適當位置時(shi),先把(ba)角(jiao)(jiao)碼(ma)與(yu)(yu)膨脹(zhang)螺(luo)栓(shuan)連(lian)接(jie)好,待龍(long)(long)(long)骨(gu)(gu)到位時(shi),在(zai)把(ba)角(jiao)(jiao)碼(ma)的(de)(de)另一端(duan)與(yu)(yu)龍(long)(long)(long)骨(gu)(gu)連(lian)接(jie),然后套上(shang)彈簧墊用螺(luo)母緊好。
鋁(lv)塑(su)板幕墻工(gong)程(cheng)質(zhi)量(liang)應遵照(zhao)國家標準《鋁(lv)塑(su)復合(he)板幕墻工(gong)程(cheng)施工(gong)及(ji)驗收規程(cheng)》及(ji)其他有關規范規定。外龍骨支撐系(xi)統及(ji)附件要(yao)安裝牢固,不(bu)要(yao)有松動現(xian)象。焊(han)接處要(yao)保(bao)(bao)證防腐漆涂刷。分(fen)格(ge)縫(feng)寬度要(yao)均勻一致。分(fen)格(ge)縫(feng)打膠時(shi),要(yao)保(bao)(bao)證其飽滿程(cheng)度及(ji)膠面的(de)平整度。撕(si)鋁(lv)塑(su)板保(bao)(bao)護(hu)膜(mo)時(shi),應小心(xin)謹慎(shen),愛護(hu)成品。
