'卫生间及其他用水房间聚氨酯防水涂料施工工法1前言随着现代社会经济发展和技术进步,对工业建筑防水提出了多样化、高性能的使用要求。聚氨酯防水涂料有着优异的防水效果,稳定的物理、学性能以及施工方便等因素。它既能满足设计要求,又通过业主的实际使用,取得了良好的应用效果。国家大力投资对聚氨酯防水涂料的技术研究,目前与发达国家的差距正逐渐缩小,产量也逐年加大,其性能将会越来越环保,外观,相信随着聚氨酯防水涂料技术的不断成熟,新品种的不断也将出现越多姿多彩。总之,聚氨酯防水涂料具有明显的社会效益和经济效益,建设工程中应用现状和前景十分广阔。为提高和保证涂料防水质量,并推广和使用聚氨酯防水涂料技术,在此整理、总结本工法。2工法特点2.0.1聚氨酯施工固化前成粘稠状液态,因此,不仅能在水平面,而且能在立面、阴阳角及各种复杂表面上形成无接缝的完整防水膜2.0.2自然流平,延伸性好,能克服基层开裂带来的渗漏2.0.3使用时无需加热,既能减少环境污染,又便于操作,改善工作条件2.0.4适合各种复杂形状部位施工,并连续一体,可避免接缝差而引起的渗漏2.0.5可潮湿施工(无明水情况下),粘附力强,以缩短工期。2.0.6形成的防水膜有较好的延伸性、耐水性和耐腐蚀性,耐温变可达100℃~-40℃。抗张强度、抗裂、耐老化都优于普通防水涂料。3适用范围本工法适用于一般工业与民用建筑卫生间及其他用水房间的工程。4工艺原理聚氨酯是反应型涂料的一种,聚氨酯防水涂膜一般是以过量的异氰酸酯化合物和多元醇类进行反应,生成末端带有异氰酸基的高分子化合物,简称预聚体(主剂),副剂则是用来和其反应以制成胶状弹性体的,它是由交联剂(与异氰酸酯进行反应的活性胺基化合物)与填料、改性剂、稀释剂以及用来调节反应速度的催化剂,经混合搅拌而成。主剂及副剂是经过科学的计算而得出的最佳配合比,需现场配料准确,搅拌均匀,才能确保质量,因此对施工工艺的要求较严格。 5施工工艺流程及操作要点periodicallycheckthesecuritysystem,checkthespecialprocesswithimplementationofthepermitsystem.5,securityresponsibilitiesshouldbestrengthenedontheconstructionsite,aswellascamphygiene,foodhygiene,publicfiresafetyandotheraspectsoftheworkofthemanagement,topreventallaccidentsfromhappening.6,intheconstructionarea,thesignsshouldbesettominimizetheconstructionofpedestrianinterference,payattentiontosafety.Truckwhenseedlingsdisplayonthepavement,and...On.Iffullofcables,electricalequipmentfails,electriciansmustberesponsibleforrepairs,othersmaynot.Switchandthepowerswitchmustbeunlockedwithspecialswitches.Fiveimportantsafetyprocesscontrolofconstructionschemeandspecialoperations(a)safetyprecautions1,establishandimprovethequalificationofsafetyofficerinsecurityorganizationsandtodevelopmeasuresofsafetymanagementandensuresafeandcivilizedconstructionsitesatthecitylevel.2,theconstructionworkersenteringthesitemustbeinthethree-tiersecurityeducation,educationofupto100%.Electricians,specialoperationspersonnelmustbetrained,andpassacertificateallowingoperation,certificatesofupto100%.3,Earthexcavationtoexploreundergroundpipestopreventtheoccurrenceofaccidents,hasspecialmonitoringduringexcavationofFoundationpitsituation,preventingcollapsehurts.(B)provisionalmeasures1,strengthenconstructionmanagementconstructionmanagementandsafetyeducationforconstructionworkers.2,on-siteelectricalequipmentwithoutpassinginspectionarenotallowedtouseelectricalequipmentshouldbemaintainedinnormalworkingcondition,nofaultruns.3,electricalequipmenterectionrain9

渗漏:防水层渗漏水,多发生在穿过楼板的管根、地漏、卫生洁具及阴阳角等部位,原因是管根、地漏等部件松动、粘结不牢、涂刷不严密或防水层局部损坏,部件接槎封口处搭接长度不够所造成。在涂膜防水层施工前,应认真检查并加以修补。7.2质量保证措施7.2.1聚氯酯防水涂料保证质量的关键是:配合比正确,搅拌充分,根据气候条件随拌随用;薄涂多刷,确保厚度,涂刷均匀,养护充分。7.2.2严把材料关,防水材料的资料(包括产品合格证、防水材料准用证及防伪标志等)要齐全,材料进场后应现场进行抽样复检。7.2.3严格按照施工规范施工,施工前对全体操作人员进行技术交底,精心进行施工。7.2.4加强对基层平整度、含水率、清洁度的控制。基层要满足防水施工要求,经有关人员验收合格后,方可进行防水涂料施工。7.2.5在浇注混凝土保护层过程中,不慎损坏的防水层要及时修补。8安全措施8.0.1施工必须符合《建设工程施工安全技术操作规程》,操作人员持证上岗,并进行安全技术交底,遵守用电安全规则。8.0.2施工用的材料必须用密封的容器包装,存放材料的库房和施工现场应通风良好。8.0.3聚氨酯甲、乙料及固化剂、稀释剂等均为易燃品,储存时应放在干燥和远离火源的场所,施工现场严禁烟火,应配备消防器材。8.0.4皮肤沾污了聚氨酯材料较难清洗,操作人员应带手套和口罩。9环保措施9.0.1在运输、堆放、施工过程中应注意避免扬尘、遗漏、沾带等现象,应采用遮盖、封闭、洒水、冲洗等必要措施。9.0.2聚氨酯材料施工工具和设备应在树脂尚未固化前,用溶剂清洗(在民用建筑工程室内严禁用有机溶剂清洗施工用具)。9.0.3聚氨酯材料使用后,应及时封闭存放;施工中生成的建筑垃圾要及时清理、清运,按环保要求分类消纳。10效益分析聚氨酯防水涂料适合我国的国情,有利生态环保,适合建筑施工节能减排的要求,是改变我国防水涂层落后的面貌的理想材料之一,符合建筑行业发展的前景,采用本工法施工,我公司加强对聚氨酯防水涂料施工的控制,可以有效的减少问题缺陷点,防水质量有了显著提高。11应用实例periodicallycheckthesecuritysystem,checkthespecialprocesswithimplementationofthepermitsystem.5,securityresponsibilitiesshouldbestrengthenedontheconstructionsite,aswellascamphygiene,foodhygiene,publicfiresafetyandotheraspectsoftheworkofthemanagement,topreventallaccidentsfromhappening.6,intheconstructionarea,thesignsshouldbesettominimizetheconstructionofpedestrianinterference,payattentiontosafety.Truckwhenseedlingsdisplayonthepavement,and...On.Iffullofcables,electricalequipmentfails,electriciansmustberesponsibleforrepairs,othersmaynot.Switchandthepowerswitchmustbeunlockedwithspecialswitches.Fiveimportantsafetyprocesscontrolofconstructionschemeandspecialoperations(a)safetyprecautions1,establishandimprovethequalificationofsafetyofficerinsecurityorganizationsandtodevelopmeasuresofsafetymanagementandensuresafeandcivilizedconstructionsitesatthecitylevel.2,theconstructionworkersenteringthesitemustbeinthethree-tiersecurityeducation,educationofupto100%.Electricians,specialoperationspersonnelmustbetrained,andpassacertificateallowingoperation,certificatesofupto100%.3,Earthexcavationtoexploreundergroundpipestopreventtheoccurrenceofaccidents,hasspecialmonitoringduringexcavationofFoundationpitsituation,preventingcollapsehurts.(B)provisionalmeasures1,strengthenconstructionmanagementconstructionmanagementandsafetyeducationforconstructionworkers.2,on-siteelectricalequipmentwithoutpassinginspectionarenotallowedtouseelectricalequipmentshouldbemaintainedinnormalworkingcondition,nofaultruns.3,electricalequipmenterectionrain9
本工法成功地应用于乌山西路凤湖片2A地块安置房工程,符合工程质量规范和合同要求。现以乌山西路凤湖片2A地块安置房工程为实例。11.1乌山西路凤湖片2A地块安置房工程11.1.1乌山西路凤湖片2A地块安置房工程位于福州市乌山西路,为厦门市重点建设项目。本工程分为两大部分,一部分为宿舍楼,另一部分为训练中心。训练中心建筑结构复杂,施工难度大,其中模拟机大厅、航材库、维护室等地面采用环氧树脂自流平地面,合计面积达4300m2。环氧树脂自流平地面由基层、环氧树脂底漆、环氧树脂砂浆、环氧树脂自流平面漆组成。11.1.2经公司工程部、总工办专业技术人员审核并经公司总经理批准形成了《环氧树脂自流平地面施工作业指导书》,编号为HY2008-05,并在公司内部推广应用。11.1.32009年2月28日我们对施工完成3个月后的模拟机大厅、航材库、维护室等区域进行了回访检查,由于成品保护得当,该些区域的环氧树脂自流平地面观感仍然光亮如新。该项目已通过2009年度“闽江杯”福建省优质工程现场核验,质量优良。该QC成果在2009年分获省和全国工程建设QC成果一、二等奖。该项目实施环氧树脂自流平地面后,对地面起到除尘、防静电、耐磨等良好效果,提高地面使用年限,减少地面维修费用,不失为较适宜的建筑工艺,也为创省优争光添色。、periodicallycheckthesecuritysystem,checkthespecialprocesswithimplementationofthepermitsystem.5,securityresponsibilitiesshouldbestrengthenedontheconstructionsite,aswellascamphygiene,foodhygiene,publicfiresafetyandotheraspectsoftheworkofthemanagement,topreventallaccidentsfromhappening.6,intheconstructionarea,thesignsshouldbesettominimizetheconstructionofpedestrianinterference,payattentiontosafety.Truckwhenseedlingsdisplayonthepavement,and...On.Iffullofcables,electricalequipmentfails,electriciansmustberesponsibleforrepairs,othersmaynot.Switchandthepowerswitchmustbeunlockedwithspecialswitches.Fiveimportantsafetyprocesscontrolofconstructionschemeandspecialoperations(a)safetyprecautions1,establishandimprovethequalificationofsafetyofficerinsecurityorganizationsandtodevelopmeasuresofsafetymanagementandensuresafeandcivilizedconstructionsitesatthecitylevel.2,theconstructionworkersenteringthesitemustbeinthethree-tiersecurityeducation,educationofupto100%.Electricians,specialoperationspersonnelmustbetrained,andpassacertificateallowingoperation,certificatesofupto100%.3,Earthexcavationtoexploreundergroundpipestopreventtheoccurrenceofaccidents,hasspecialmonitoringduringexcavationofFoundationpitsituation,preventingcollapsehurts.(B)provisionalmeasures1,strengthenconstructionmanagementconstructionmanagementandsafetyeducationforconstructionworkers.2,on-siteelectricalequipmentwithoutpassinginspectionarenotallowedtouseelectricalequipmentshouldbemaintainedinnormalworkingcondition,nofaultruns.3,electricalequipmenterectionrain9'
