1、外墻保(bao)溫(wen)板的(de)粘貼應從門窗邊上(shang)以及墻角等(deng)部(bu)位開始,逐(zhu)步向(xiang)著中間進(jin)行(xing)(xing)。一個區段內的(de)鋪貼要(yao)由下向(xiang)上(shang)進(jin)行(xing)(xing)。聚氨酯保(bao)溫(wen)板應以長(chang)向(xiang)水平鋪貼,保(bao)證連續結合(he),而且上(shang)下兩(liang)排保(bao)溫(wen)板豎(shu)向(xiang)上(shang)應該錯(cuo)縫粘鋪,錯(cuo)縫一般為1/2板長(chang),有些(xie)局部(bu) 小錯(cuo)縫不(bu)得小于200mm。
2、在粘(zhan)貼外墻陽(yang)角和門窗框(kuang)四(si)周(zhou)的陽(yang)角時,按照預先(xian)彈出(chu)的基準線施工(gong),同(tong)時門窗洞(dong)口(kou)角部的聚(ju)氨酯保(bao)溫板要整板粘(zhan)結,不(bu)應在此處出(chu)現保(bao)溫板拼縫。
3、在拐角處,按照預先排好的尺寸(cun)粘貼,垂(chui)直(zhi)粘結交(jiao)錯連接,拐角處要保證順直(zhi)且完(wan)整。
4、在(zai)保(bao)溫板上(shang)涂抹(mo)粘結灰漿(jiang),涂抹(mo)的灰漿(jiang)面積要大于40%。涂抹(mo)好后立即(ji)將(jiang)保(bao)溫板輕柔擠壓貼在(zai)墻上(shang)。
5、將保溫(wen)板(ban)(ban)(ban)貼(tie)(tie)在墻上(shang)時(shi),要隨時(shi)使用(yong)2米靠尺進行反復壓平操作,并與相(xiang)鄰板(ban)(ban)(ban)面拍平,保證板(ban)(ban)(ban)與板(ban)(ban)(ban)間高差不(bu)(bu)得(de)大于1.5mm,保證保溫(wen)板(ban)(ban)(ban)的(de)平整度(du)并能粘(zhan)結牢固(gu)。每貼(tie)(tie)完一塊我(wo)們要及時(shi)將保溫(wen)板(ban)(ban)(ban)四邊擠出的(de)粘(zhan)接砂(sha)漿清除掉,以免板(ban)(ban)(ban)縫(feng)間有粘(zhan)接砂(sha)漿;板(ban)(ban)(ban)與板(ban)(ban)(ban)之(zhi)間要擠緊(jin),縫(feng)隙(xi)(xi)(xi)不(bu)(bu)得(de)大于2mm,如不(bu)(bu)得(de)已縫(feng)隙(xi)(xi)(xi)大于2毫米時(shi),縫(feng)隙(xi)(xi)(xi)要使用(yong)保溫(wen)板(ban)(ban)(ban)條(tiao)塞滿或使用(yong)發泡聚氨酯填(tian)塞,切記(ji)不(bu)(bu)要用(yong)粘(zhan)結砂(sha)漿或其它膠粘(zhan)劑粘(zhan)結板(ban)(ban)(ban)條(tiao),否則該部位(wei)會形成冷(leng)、熱橋;如果(guo)是因為保溫(wen)板(ban)(ban)(ban)裁切不(bu)(bu)直而引(yin)起的(de)縫(feng)隙(xi)(xi)(xi),要用(yong)木銼(cuo)(cuo)銼(cuo)(cuo)直后再(zai)粘(zhan)貼(tie)(tie)。
6、遇(yu)到(dao)腳手架連接墻體以(yi)及其它有(you)突出(chu)墻面但(dan)以(yi)后需要(yao)拆(chai)(chai)除(chu)的地方,要(yao)預(yu)留整幅聚氨酯(zhi)保(bao)溫板(ban), 后邊拆(chai)(chai)除(chu)邊收(shou)尾施(shi)工。(來(lai)源:中國保(bao)溫網)
