煙囪刷油漆防腐施工方(fang)案
(一(yi))、施工(gong)順(shun)序:下料→防(fang)腐處理→焊(han)接安裝→焊(han)接處防(fang)腐處理
(二)下料(liao)(liao) 根據業主方提供的100米煙囪圖紙,由技術人員(yuan)計算出整個(ge)囪身(shen)旋轉爬梯所需的材料(liao)(liao),并結合圖紙上尺寸,由操(cao)作(zuo)工切(qie)(qie)割(ge)下料(liao)(liao),技術員(yuan)全程指導。材料(liao)(liao)全部切(qie)(qie)割(ge)好后進行熱浸鋅(xin)防腐處理。
(三)平臺(tai)(tai)焊(han)(han)接(jie)安裝結合我施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)隊(dui)多年的旋(xuan)轉爬梯及平臺(tai)(tai)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)經驗(yan)及貴公司的實(shi)際(ji)情況,我公司擬定(ding)以下施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)方(fang)案: 1、本工(gong)(gong)(gong)(gong)(gong)(gong)程采(cai)用不(bu)搭腳(jiao)手架(jia)、懸吊(diao)作(zuo)業新(xin)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)、新(xin)技術(shu)進行施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)。主要(yao)采(cai)用“人工(gong)(gong)(gong)(gong)(gong)(gong)登(deng)高法”結合帶、白棕繩(sheng)等必要(yao)的工(gong)(gong)(gong)(gong)(gong)(gong)具進行施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)。2、對100米煙囪身(shen)從下向上依(yi)次(ci)(ci)焊(han)(han)接(jie)安裝,將(jiang)塊踏(ta)步(bu)板焊(han)(han)接(jie)在(zai)(zai)囪身(shen)后,就依(yi)塊板為作(zuo)業平臺(tai)(tai)依(yi)次(ci)(ci)向上逐步(bu)焊(han)(han)接(jie)安裝。同時(shi)準備(bei)兩臺(tai)(tai)焊(han)(han)機,一(yi)臺(tai)(tai)焊(han)(han)接(jie)負(fu)責焊(han)(han)接(jie)安裝踏(ta)步(bu)板,另一(yi)臺(tai)(tai)負(fu)責焊(han)(han)接(jie)欄桿(gan)及加(jia)固(gu)用。3、在(zai)(zai)焊(han)(han)接(jie)安裝平臺(tai)(tai)時(shi),先將(jiang)平臺(tai)(tai)三角支(zhi)撐焊(han)(han)接(jie)固(gu)定(ding)在(zai)(zai)囪身(shen),后再(zai)鋪焊(han)(han)平臺(tai)(tai)板。4、對踏(ta)步(bu)板、平臺(tai)(tai)及欄桿(gan)等焊(han)(han)接(jie)處進行油漆防腐。
(四)、平臺(tai)基(ji)材刷(shua)防銹漆
1、基層(ceng)表(biao)(biao)面(mian)(mian)(mian)(mian)處(chu)(chu)理(li) 根據我公司鋼(gang)結構(gou)防腐長期施工(gong)總結,基層(ceng)表(biao)(biao)面(mian)(mian)(mian)(mian)處(chu)(chu)理(li)的(de)(de)(de)(de)(de)質量好壞(huai)直(zhi)接影響(xiang)防腐涂(tu)(tu)料的(de)(de)(de)(de)(de)附著力,所以(yi)必須采(cai)用(yong)電動打(da)磨(mo)機、鋼(gang)絲(si)刷(shua)等(deng)(deng)對鋼(gang)結構(gou)表(biao)(biao)面(mian)(mian)(mian)(mian)進行打(da)磨(mo)處(chu)(chu)理(li)。除(chu)銹后(hou)的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)在(zai)涂(tu)(tu)裝(zhuang)前清理(li)干(gan)凈鋼(gang)結構(gou)表(biao)(biao)面(mian)(mian)(mian)(mian)無氧化(hua)皮(pi)(pi)、灰塵等(deng)(deng),并(bing)立即(ji)涂(tu)(tu)裝(zhuang),以(yi)免引起(qi)二次生銹。 表(biao)(biao)面(mian)(mian)(mian)(mian)預(yu)處(chu)(chu)理(li):鋼(gang)材在(zai)進入除(chu)銹前,確認表(biao)(biao)面(mian)(mian)(mian)(mian)無油脂、其它污(wu)(wu)染物等(deng)(deng),如有(you),使(shi)用(yong)堿性清潔劑或淡水以(yi)去除(chu)結構(gou)表(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)(de)(de)油脂、污(wu)(wu)物、可(ke)溶性鹽份和(he)其它污(wu)(wu)染物。清洗完畢后(hou),自(zi)然晾干(gan)后(hou),才可(ke)進行后(hou)續處(chu)(chu)理(li)。 鋼(gang)材表(biao)(biao)面(mian)(mian)(mian)(mian)清理(li)干(gan)凈后(hou)檢驗結構(gou)的(de)(de)(de)(de)(de)焊接和(he)外觀(guan),以(yi)發(fa)現存在(zai)的(de)(de)(de)(de)(de)結構(gou)缺(que)陷并(bing)及時(shi)處(chu)(chu)理(li)。 用(yong)電動鋼(gang)絲(si)刷(shua)、磨(mo)光機等(deng)(deng)動力工(gong)具清除(chu)鋼(gang)材表(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)(de)(de)氧化(hua)皮(pi)(pi)。有(you)的(de)(de)(de)(de)(de)自(zi)由邊(bian)、角使(shi)用(yong)磨(mo)機處(chu)(chu)理(li)至R≥2mm。清除(chu)所有(you)的(de)(de)(de)(de)(de)焊渣、飛(fei)濺和(he)焊豆。咬(yao)邊(bian)和(he)氣孔(kong)采(cai)取補(bu)并(bing)磨(mo)平。 手工(gong)焊縫采(cai)取打(da)磨(mo)處(chu)(chu)理(li)以(yi)減少尖銳的(de)(de)(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)(mian)存在(zai)。對于修補(bu)表(biao)(biao)面(mian)(mian)(mian)(mian)邊(bian)緣的(de)(de)(de)(de)(de)原有(you)涂(tu)(tu)層(ceng),使(shi)用(yong)動力砂紙圓盤羽化(hua)邊(bian)緣,形(xing)成光順的(de)(de)(de)(de)(de)斜坡,以(yi)利于修補(bu)油漆(qi)與原有(you)涂(tu)(tu)層(ceng)的(de)(de)(de)(de)(de)光順過 渡,保(bao)證整個涂(tu)(tu)層(ceng)的(de)(de)(de)(de)(de)良(liang)好外觀(guan)和(he)漆(qi)膜的(de)(de)(de)(de)(de)均勻。
