立敦電子防水維修（pvc卷材）施工方案

立敦電子彩鋼廠房防水維修（PVC卷材）施工方案成都宇華建筑工程有限公司2011年8月19日經(jīng)現(xiàn)場勘察，貴公司彩鋼瓦屋面漏水屬于原有防水密封膠老化起裂、脫縫。以及年久未進行維修養(yǎng)護，屋頂排水天溝腐蝕銹穿，因此出現(xiàn)眾多漏水部位。綜合上訴原因特制定以下施工方案1、首先將彩鋼屋面渣物進行全面清理轉(zhuǎn)運。2、屋頂排水天溝渣物及淤泥全面清理轉(zhuǎn)運。3、對清理后的排水天溝涂刷環(huán)氧富鋅防銹漆進行防銹處理。4、對所有的彩鋼瓦接縫老化的防水膠使用專用工具進行全面割除。5、清理后的彩鋼及排水天溝接縫處使用“美國道康靈”中性防水密封膠全面密封。6、接縫處理完畢后在整個屋頂彩鋼瓦上滿鋪PVC防水卷材。PVC防水卷材施工工藝如下一、編制依據(jù)（一）GB503452004屋面工程技術(shù)規(guī)范（二）GB502072002屋面工程質(zhì)量驗收規(guī)范二、施工準備（一）材料選用“圣海”牌聚氯乙烯（PVC）防水卷材，規(guī)格型號執(zhí)行標準GB125922003。L類及W類物理性能指標序號項目I型II型1拉力（N/CM）1001602斷裂伸長率/1502003熱處理尺寸變化率/15104低溫彎折性20無裂紋25無裂紋5抗穿孔性不滲水6不透水性不透水拉力變化率/斷裂伸長率變化率/25207人工氣候加速老化低溫彎折性15無裂紋20無裂紋（二）產(chǎn)品分類產(chǎn)品類型復合抗紫外線型15MM厚。主要應用于屋面防水層的大面和天溝使用。（三）系統(tǒng)配件三、施工工藝流程PVC鏟除隔氣層鋪設(shè)保溫層翻面（設(shè)計確定）安裝隔離層（無紡布）鋪設(shè)防水層鋪設(shè)和機械固定熱風焊接細部和收口處理檢查、驗收四、施工1、清理基面，表面的油污、雜物等其它建筑垃圾全部清掃干凈?；娣鲜┕l件后，彈線定位。2、將防水卷材空鋪就位,防水卷材的預留搭接寬度為100MM。3、為了減少焊接縫,防水卷材根據(jù)現(xiàn)場情況采取橫鋪。4、防水卷材搭接一般為上板壓下板,使外部的水順接槎向下流，不會在焊縫處積聚，形成滲水隱患。5、周邊防水卷材收口處用雙排固定件固定，固定點距檐口100MM，固定點的間距為200MM，最后用200MM寬的PVC焊條熱風焊接在壓條上面加以覆蓋。屋面橫向每10M設(shè)固定件固定，最后用200MM寬的PVC焊條熱風焊接在壓條上面加以覆蓋。鋪設(shè)PVC防水卷材專用膠粘劑機械固定專用墊片（熱度）抗拔釘金屬壓條改性PVC防水卷材熱風焊接背襯（隔離層）卷材固定件保溫板隔汽層（涂料/改性瀝青/PE膜）輕鋼屋面PVC卷材時，縱向每隔2米用固定件固定，間距為200MM，搭接處采用熱風焊接。PVC卷材遇立面處用膠水滿粘，并用鋁合金壓條固定，射釘間距為200MM，最后滿涂聚氨酯密封膏。6、PVC防水卷材按上述方法鋪設(shè)完畢后，可以進行焊接工作。焊接防水卷材將防水卷材的搭接處擦拭干凈，采用熱風焊接機焊接防水卷材搭接縫。根據(jù)材料選定溫度和速度,焊接時焊接邊緣應有漿液溢出，呈亮色，不可出現(xiàn)燒焦現(xiàn)象。防水卷材鋪設(shè)時拉伸宜松不宜緊。7、防水卷材破損后的修補用手動熱風焊槍將修補用的防水卷材焊接在被修部位及外延50MM處即可。8、手工焊縫的施工及加強手工焊縫時，焊嘴與焊接方向呈4550度角，壓輥與焊嘴平行并保持大約5MM的距離。焊接邊緣應有溶漿溢出，呈亮色，不應出現(xiàn)燒焦現(xiàn)象。焊接時從一端開始，邊焊接邊排除空氣。焊接后及時用手壓輥按順序滾壓一遍，接縫處不允許有氣泡、皺折存在。拐角等部位均需要用PVC焊條進行加強處理。9、雨篦子處的PVC施工方法先按照雨水口的尺寸把PVC裁剪成條狀，并用焊槍焊接成雨水口的形狀，長度約伸入雨水口20CM，然后放入雨水口，上端用熱風焊槍焊接在PVC卷材上，局部用PVC條進行加強處理。機械固定系統(tǒng)PVC輕鋼結(jié)構(gòu)屋面節(jié)點示意圖成都宇華建筑工程有限公司2011年8月19日GANEMPLOYMENTTRIBUNALCLAIMEMPLOYMENTTRIBUNALSSORTOUTDISAGREEMENTSBETWEENEMPLOYERSANDEMPLOYEESYOUMAYNEEDTOMAKEACLAIMTOANEMPLOYMENTTRIBUNALIFYOUDONTAGREEWITHTHEDISCIPLINARYACTIONYOUREMPLOYERHASTAKENAGAINSTYOUYOUREMPLOYERDISMISSESYOUANDYOUTHINKTHATYOUHAVEBEENDISMISSEDUNFAIRLYFORMOREINFORMATIONABOUTDISMISSALANDUNFAIRDISMISSAL,SEEDISMISSALYOUCANMAKEACLAIMTOANEMPLOYMENTTRIBUNAL,EVENIFYOUHAVENTAPPEALEDAGAINSTTHEDISCIPLINARYACTIONYOUREMPLOYERHASTAKENAGAINSTYOUHOWEVER,IFYOUWINYOURCASE,THETRIBUNALMAYREDUCEANYCOMPENSATIONAWARDEDTOYOUASARESULTOFYOURFAILURETOAPPEALREMEMBERTHATINMOSTCASESYOUMUSTMAKEANAPPLICATIONTOANEMPLOYMENTTRIBUNALWITHINTHREEMONTHSOFTHEDATEWHENTHEEVENTYOUARECOMPLAININGABOUTHAPPENEDIFYOURAPPLICATIONISRECEIVEDAFTERTHISTIMELIMIT,THETRIBUNALWILLNOTUSUALLYACCEPTITIFYOUAREWORRIEDABOUTHOWTHETIMELIMITSAPPLYTOYOU,TAKEADVICEFROMONEOFTHEORGANISATIONSLISTEDUNDERFURTHERHELPEMPLOYMENTTRIBUNALSARELESSFORMALTHANSOMEOTHERCOURTS,BUTITISSTILLALEGALPROCESSANDYOUWILLNEEDTOGIVEEVIDENCEUNDERANOATHORAFFIRMATIONMOSTPEOPLEFINDMAKINGACLAIMTOANEMPLOYMENTTRIBUNALCHALLENGINGIFYOUARETHINKINGABOUTMAKINGACLAIMTOANEMPLOYMENTTRIBUNAL,YOUSHOULDGETHELPSTRAIGHTAWAYFROMONEOFTHEORGANISATIONSLISTEDUNDERFURTHERHELPIFYOUAREBEINGREPRESENTEDBYASOLICITORATTHETRIBUNAL,THEYMAYASKYOUTOSIGNANAGREEMENTWHEREYOUPAYTHEIRFEEOUTOFYOURCOMPENSATIONIFYOUWINTHECASETHISISKNOWNASADAMAGESBASEDAGREEMENTINENGLANDANDWALES,YOURSOLICITORCANTCHARGEYOUMORETHAN35OFYOURCOMPENSATIONIFYOUWINTHECASEIFYOUARETHINKINGABOUTSIGNINGUPFORADAMAGESBASEDAGREEMENT,YOUSHOULDMAKESUREYOURECLEARABOUTTHETERMSOFTHEAGREEMENTITMIGHTBEBESTTOGETADVICEFROMANEXPERIENCEDADVISER,FOREXAMPLE,ATACITIZENSADVICEBUREAUTOFINDYOURNEARESTCAB,INCLUDINGTHOSETHATGIVEADVICEBYEMAIL,CLICKONNEARESTCABFORMOREINFORMATIONABOUTMAKINGACLAIMTOANEMPLOYMENTTRIBUNAL,SEEEMPLOYMENTTRIBUNALSTHELACKOFAIRUPTHEREWATCHMCAYMANISLANDSBASEDWEBB,THEHEADOFFIFASANTIRACISMTASKFORCE,ISINLONDONFORTHEFOOTBALLASSOCIATIONS150THANNIVERSARYCELEBRATIONSANDWILLATTENDCITYSPREMIERLEAGUEMATCHATCHELSEAONSUNDAY“IAMGOINGTOBEATTHEMATCHTOMORROWANDIHAVEASKEDTOMEETYAYATOURE,“HETOLDBBCSPORT“FORMEITSABOUTHOWHEFELTANDIWOULDLIKETOSPEAKTOHIMFIRSTTOFINDOUTWHATHISEXPERIENCEWAS“UEFAHASOPENEDDISCIPLINARYPROCEEDINGSAGAINSTCSKAFORTHE“RACISTBEHAVIOUROFTHEIRFANS“DURINGCITYS21WINMICHELPLATINI,PRESIDENTOFEUROPEANFOOTBALLSGOVERNINGBODY,HASALSOORDEREDANIMMEDIATEINVESTIGATIONINTOTHEREFEREESACTIONSCSKASAIDTHEYWERE“SURPRISEDANDDISAPPOINTED“BYTOURESCOMPLAINTINASTATEMENTTHERUSSIANSIDEADDED“WEFOUNDNORACISTINSULTSFROMFANSOFCSKA“AGEHASREACHEDTHEENDOFTHEBEGINNINGOFAWORDMAYBEGUILTYINHISSEEMSTOPASSINGALOTOFDIFFERENTLIFEBECAMETHEAPPEARANCEOFTHESAMEDAYMAYBEBACKINTHEPAST,TOONESELFTHEPARANOIDWEIRDBELIEFDISILLUSIONMENT,THESEDAYS,MYMINDHASBEENVERYMESSY,INMYMINDCONSTANTLYALWAYSFEELONESELFSHOULDGOTODOSOMETHING,ORWRITESOMETHINGTWENTYYEARSOFLIFETRAJECTORYDEEPLYSHALLOW,SUDDENLYFEELSOMETHING,DOIT一字開頭的年齡已經(jīng)到了尾聲?；蛟S是愧疚于自己似乎把轉(zhuǎn)瞬即逝的很多個不同的日子過成了同一天的樣子；或許是追溯過去，對自己那些近乎偏執(zhí)的怪異信念的醒悟，這些天以來，思緒一直很凌亂，在腦海中不斷糾纏?？傆X得自己自己似乎應該去做點什么，或者寫點什么。二十年的人生軌跡深深淺淺，突然就感覺到有些事情，非做不可了。THEENDOFOURLIFE,ANDCANMEETMANYTHINGSREALLYDO而窮盡我們的一生，又能遇到多少事情是真正地非做不可DURINGMYCHILDHOOD,THINKLUCKYMONEYANDNEWCLOTHESARENECESSARYFORNEWYEAR,BUTASTHEADVANCEOFTHEAGE,WILLBEMOREANDMOREFOUNDTHATTHOSETHINGSAREOPTIONALJUNIORHIGHSCHOOL,T
