概要:整体地面主要是指混凝土地面、水泥砂浆地面、现浇水磨石地面和菱苦土地面等。这是一种应用于更为普遍、具备传统作法的地面,其基层和垫层的作法完全相同,仅有面层所用材料和施工方法有所区别。绝大部分工程的基层和垫层在土建工程中已完成,在装饰工程中仅有展开面层的施工。

由于在实际工程中应用于水泥砂浆地面和现浇水磨石地面较多,所以本文重点讲解这两种地面的施工工艺。Abstract:thewholegroundismainlyreferstotheconcretegroundwater,cementmortargroundandterrazzogroundandlingmagnesiaground,etc.Thisisakindofapplicationisrelativelywide,withthegroundoftradition,thegrassrootsandcushionlayeristhesame,onlydifferentsurfacematerialsandconstructionmethods.Mostoftheengineeringofgrass-rootsandcushionincivilworkscompleted,onlyinthedecorationprojectcarriesonthesurfaceoftheconstruction.Becauseinthepracticalengineeringapplicationwatercementmortargroundandterrazzogroundismore,sothisarticlefocusesonthetwofarmingconstructionprocessbelow.  关键词:整体地面;水泥砂浆;施工;水土保持;质量Keywords:wholeground;Cementmortar;Construction;Maintenance;Thequality  章节Theintroduction  水泥砂浆地面面层是以水泥作胶静材料,以砂作骨料,按因应比提炼抹压而出。

水泥砂浆地面的优点是耗资较低、施工简单、用于耐久性,但更容易经常出现起灰、起砂、裂缝、空鼓等质量问题。Cementmortargroundsurfacewithcementascementitiousmaterial,withsandasaggregate,accordingtomixwithpressure.Cementmortargroundhastheadvantageoflowcost,simpleconstruction,durability,butit'seasytohaveagrey,sand,cracks,emptydrumsandotherqualityproblems.  1对构成材料的拒绝1requirementsforcomponentmaterials  1.1胶凝材料水泥砂浆(楼)地面所用的胶凝材料为水泥,不应优先选择硅酸盐水泥、普通硅酸盐水泥,其强度等级一般不得高于32.5MPa。以上品种的水泥与其他品种水泥比起,具备早期强度低、水化热较高、干缩性较小等优点。

如果使用矿渣硅酸盐水泥,其强度等级不应小于32.5MPa,在施工中要严苛按施工工艺操作者,并且要强化水土保持,这样才能确保工程质量。1.1gelledmaterialusedinthecementmortarground(floor)gellingmaterialforcement,shouldgivepreferencetoPortlandcement,ordinaryPortlandcement,thestrengthgradeaverageisnotlessthan32.5MPa.Theabovevarietiescomparedwithothervarietiesofcement,cementwithhighearlystrength,smalldryshrinkageandhigherhydrationheat,etc.IfusingslagPortlandcement,thestrengthgradeshouldbegreaterthan32.5MPa,strictlyoperateaccordingtoconstructiontechnologyinconstruction,andtostrengthenthemaintenance,soastoensuretheengineeringquality.  1.2细骨料水泥砂浆面层所用的细骨料为砂,一般多使用中砂和粗砂,含泥量不得小于3%(质量分数)。因为细砂的级配上很差,拌制的砂浆强度比中砂、粗砂拌制的强度大约较低25%~35%,不仅耐磨性较好,而且干缩性较小,更容易产生膨胀裂缝等质量问题。

水泥砂浆地面的施工工艺水泥砂浆地面的施工比较简单,其施工工艺流程为:基层处置弹线、去找规矩水泥砂浆抹面水土保持。1.2fineaggregateusedinthecementmortarlayerfineaggregateasthesand,morecommonlyusedmediumsandandcoarsesand,siltcontentshallnotbegreaterthan3%(massfraction).Badforfinegrading,mixingmortarstrengththanmediumsandandcoarsesandmixingintensityofabout25%~35%lower,notonlywearresistanceispoorer,andthedryshrinkageisbigger,easytoproducethequalityproblemssuchasshrinkagecrack.Cementmortargroundtheconstructiontechnologyofcementmortargroundconstructionissimpler,itsconstructiontechnologicalprocessasfollows:thebasiclevelprocessing-line,findrules-cementmortarplaster-maintenance.  2基层处置2basiclevelprocessing  水泥砂浆面层多砖沾在楼地面混凝土垫层上,基层处置是避免水泥砂浆面层再次发生空鼓、裂纹、起砂等质量通病的关键工序。因此,拒绝基层具备坚硬、洁净、干燥的表面,必需细心清理一切浮灰、油渍、杂质,否则构成一层隔绝层,不会使面层融合不牢。表面较为平滑的基层,不应展开挖毛,后用清水冲洗整洁,冲洗后的基层,最差不要上人。

在现浇混凝土或水泥砂浆垫层、找平层上做到水泥砂浆地面面层时,其抗压强度超过1.2MPa,才能铺设面层,这样不致毁坏其内部结构。Cementmortarlayermorethanshopputonfloors,concretecushionlayer,primarytreatmentistopreventthecementmortarlayerfromaemptydrum,crack,sand,etc.Thequalitycommonfaultofthekeyworkingprocedure.Therefore,grass-rootsrequirementswithrough,clean,moistsurface,mustbecarefullyremoveallfloatash,oilybesoiled,material,ortoformalayerofisolationlayer,layercombinedwithrickety.Surfaceissmoothatthegrass-rootslevel,shouldbecuthair,rinseoffwithclearwater,rinsethegrassroots,hadbetternotbehere.Incast-in-placeconcreteorcementmortarcushionlayer,makingthegroundsurfacelayerofcementmortarscreed-coat,itscompressivestrengthis1.2MPa,inordertolaidthesurface,itdoesnotdamageitsinternalstructure.  3弹线、去找规矩3line,findrules  3.1弹基准线地面抹灰前,应先在四周墙上弹头出有一道水平基准线,作为确认水泥砂浆面层标高的依据。

作法是以地面0.00为依据,根据实际情况在四周墙上插入0.5m或1.0m作为水平基准线。据水平基准线量出有地面标高并弹于墙上(水平辅助基准线),作为地面面层上皮的水平基准。要留意按设计拒绝的水泥砂浆面层厚度弹线。

地面标筋用1:2水泥砂浆,宽度一般为8~10cm。做到标筋时,要留意掌控面层标高与门框的锯口线相符。

去找平时要留意各室内地面与走廊高度的关系。3.3tofindslopeforkitchen,bathroom,toilet,etc.Thegroundoftheroom,lookingforgooddrainageslope.Haveroom,floordraintomakearoundthefloordrainisnotlessthan5%ofthewater,toavoidanygroundbackflowofwaterorwater.Lookingforatordinarytimesshouldpayattentiontotheinteriorcorridorofgroundandtheheightoftherelationship.  3.4校核去找于是以地面铺设前,还要将门框再行一次校核去找于是以。

其方法是再行将门框锯口线遗文追去找于是以,并留意当地面面层铺设后,门扇与地面的间隙不应符合规定拒绝,然后将门框相同,避免断裂、偏移。3.4checkforgroundlaidbefore,andthedoorframecheckalignmentagain.Itsmethodistoframelinecurfsightalignment,andpayattentiontothelocalsurfacelayerafterlaid,doorleafandthegroundclearanceshouldconformtotherequirementsoftherules,thenframefixed,preventlooseanddisplacement.  4水泥砂浆抹面4cementmortarplaster  面层水泥砂浆的因应比应合乎有关设计拒绝,一般不高于1:2,水灰比为1:(0.3~0.4),稠度不小于3.5cm。水泥砂浆拒绝拌和均匀分布,颜色完全一致。

压光时用力要重一些,使抹子的纹深一些,以压光后表面不经常出现水纹为宜。如果面层上有多余的水分,可根据水分的多少必要均匀分布马利亚一层腊水泥或干拌水泥砂浆来吸取面层上多余的水分,再行压实压光。但是,当表层无多余水分时,不得撒干水泥。Groundsurfacecleanshopofmethodis:inthereinforcementbetweenthemortarontheshop,andincreaseswiththeincreasingspreadusingwoodfloatandscrapetoevennesswithshortwoodenpolesaccordingtothestandardbarelevation.Inpeacetimeawayfromindoorbyyoutoshavetothedoor,andinconformitywiththeframelinecurfelevation,andthenrubbingflatinwoodfloat,anduseironfloatfollowedbypressurelightagain.Calenderwhenthestrengthshouldbelighter,makefloatlinesshallowsome,withalightsurfacedoesnotappearafterwaterpressureisadvisable.Ifthereisexcesswateronthesurface,butaccordingtohowmuchappropriatemoistureevenlysprinklealayerofdrycementordrymixingcementmortartoabsorbexcessmoistureonthesurface,lightcompactionpressureagain.But,whensurfacewithoutexcesswater,mustnotdrycement.  当水泥砂浆开始初凝时,即人摔上去有脚印但不坍塌,才可开始用铁皮抹子力第二遍。

一般夏天在24h后展开水土保持,春秋季节不应在48h后展开水土保持。当使用硅酸盐水泥和普通硅酸盐水泥时,水土保持时间不得多于7d;当使用矿渣硅酸盐水泥时,水土保持时间不得多于14d。面层强度超过5MPa以上后,才容许人在地面上行驶或展开其他作业。
