浅谈建筑现浇混凝土楼板裂缝的原因及其防治[摘要]在建筑施工中，现场浇筑的混凝土楼板裂缝是一种普遍存在的现象，这些裂缝不仅影响建筑物的美观，而且严重影响建筑物的使用功能，大大降低了房屋结构的耐久性；破坏结构的整体性、降低其刚度；引起钢筋腐蚀；是目前较难克服的质量通病之一，这些质量问题直观反映到我们日常生活中，例如：建筑屋面、浴室、阳台等渗漏水造成我们生活困扰，现就以施工为主、兼顾设计和材料原因分析楼面裂缝的成因，分析具体的预防以及措施。[关键字]现浇混凝土楼板裂缝渗漏水防治措施Discussionontheconstructionofcast-in-placeconcretefloorcrackandpreventionreasons[Abstract]Inbuildingconstruction,on-sitepouringconcretefloorcrackisauniversalphenomenon,thesecracksnotonlyaffectstheappearanceofbuildings,butalsoseriouslyaffecttheuseofthebuildingfunction,greatlyreducethedurabilityofbuildingstructures;destroyunity,structureandreducethestiffness;causedbycorrosionofreinforcementisoneofthecommonqualitydefectsofrelatively;difficulttoovercomeatpresent,thesequalityproblemsdirectlyreflecttoourdailylife,suchas:buildingroof,balcony,bathroomisotonicWaterLeakagecausedourtroublesoflife,nowmainlyinconstruction,analysisofbothdesignandmaterialreasoncausesoffloorcracks,concreteanalysisandmeasuresofprevention.[keyword]OfCast-in-placeConcreteFloorCrackWaterLeakageInfiltrationPreventionMeasures目录引言.........................................................................1一、裂缝产生的原因及分类.......................................................1（一）设计方面原因........................................................................................................................................2（二）材料方面原因........................................................................................................................................3（三）施工方面原因........................................................................................................................................4二、裂缝一般性防治措施.........................................................5（一）设计方面的预防措施............................................................................................................................5（二）材料方面的预防措施............................................................................................................................6（三）施工方面的预防措施............................................................................................................................7三、现场施工中重点关注部位的处理措施...........................................8（一）重点加强楼面上层钢筋网的有效保护措施。....................................................................................8（二）预埋线管处的裂缝防治措施................................................................................................................9（三）材料吊卸区域的楼面裂缝防治............................................................................................................9（四）加强对楼面砼的养护..........................................................................................................................10（五）控制建筑荷载，减小沉降量沉降差的措施......................................................................................10四、裂缝产生后的弥补措施......................................................12五、工程实例..........................................
