F数值规范替代。FFandFLcriteriaisestablishedbyAmericanConcreteInstitute#117andCanadianStandardAssociation#A23.1tospecifyandmeasuretheflatnessandlevelnessofconcretefloor.Itcontains2values:FF-floorflatness,reflectingtheconvexandconcave,FL-floorlevelness,reflectinginclineandheightdifference.TheFvalueislinearrelationship.TheFvalueishigher,thefloorisflatter.F20is2timesasflatasF10,buthalfasflatasF40.F数值为美同混凝土协会(AmericanConcreteInstitute#117)及加拿大标准协会(CanadianStandardAssociation#A23.1)为规范及测量混凝土地坪平整及高差的标准。此规范包括两个F数值:FF为平整度,FL为高差值,平整度关系着地坪的隆起与凹陷.高差值关系着地坪的倾斜或高差。也就是说平整度FF表示地坪整体意义的起伏程度,水平度FL表示地坪整体意义的倾斜程度。愈高的F数值代表地坪的平整度愈佳。F数值为线性关系,因此F20比F10要平整2倍,却只有F40的1/2平。Diagram3FF/FLintervalforsuper-flatfloor图3 高平整度要求地坪的FF/FL区间Diagram4AmericanFloorPromodelⅧautomeasureinstrumentforflatnessand156

最后每个检测组的数据就汇总出整个测试区域的数据。输入计算机得到最终的平整度数据。具体计算过程参见《ANSI/ASTME1155Ma一1996使用F-数字系统测定楼板平整度和水平度的试验方法(米制)》。 图5 地面高差情况曲线图Diagram6IntervalofmeasuredFF/FL图6 测得FF/FL值所处区间图Formofmeasuredflatness平整度测试报表No.Testlength(ft)试验长度(英尺)FlatnessFF平整度LevelnessFL水平度13353.154.623263.25233350.751.843358.353.5532.565.155.163355.650.4732.551.347.9832.558.746.1931.566581032.561.763.2156

在清理干净的找平层上,依照室内标准水平线,校核一下地面标高和分格线。以所弹地干线为依据,设置支撑瓷片或瓷砖的地面木托板。加木托的目的是防止贴瓷片时在水泥浆未硬化的砖体下坠。木托板表面应加工平整。其高度为非整块瓷片的调节尺寸。整块瓷片的墙面铺贴,就从木托板开始自下而上进行。Mortarismadebyaratioof1:2(volume)forcementvssand,inwhich108glueismixedby3to4percent.Firstly,dilutethegluewithwatertwotimesthatoftheglueitself,thenputthemixturetothemortarforafurthermixing.Withashovel,themixtureisappliedtotheceramictileoritsback.Itshallnotbemorethan5mmintermsofitsthickness.Allitsfourcornersshallbeinclinedtoplaceandpressedbyhand,thenknockedbyrubberhammertoground.Itisnotedthattheglazedtileshallbefullygluedandleveledbyruler.调制糊状的水泥浆,其配合比为水泥:砂=1:2(体积比),另外掺加水泥重量3%~4%的108胶水。先将108胶用两倍的水稀释,然后加在搅拌均匀的水泥砂浆中,继续搅拌至充分混和为止。镶贴时,用铲刀将聚合物水泥浆均匀涂抹在瓷片或瓷砖背面,厚度不在大5mm,四周刮成斜面,按线就位后,用手轻压,然后用橡皮锤轻轻敲击,使其与底层贴紧,并注意确保釉面砖四周砂浆饱满,并用靠尺找平。Optionally,itcanbedonewiththemixtureofcementandgluewiththeratioof100:5.26.Thissortofmortarshallbefinishedallatonetime.Itisespeciallysuitableforwall,whichhasbeenleveledwithashpreviously.也可按水泥:108胶水:=100:5:26的比例配制纯水泥浆进行铺贴,这种水泥浆应随拌随用,并在收工前全部用完。它最适合底灰较平整的墙面。Beforethewalloflargesizeisworked,severaldiscardedceramictilesaretobelaidfortesting.Theyaretobeleveledbywoodenrulerorlevelrod.Onesignalpieceistobesetevery1.5minthehorizontaldirection.铺贴大面前,应先贴若干块废瓷砖片作为标准厚度块,用木靠尺和水平尺确定其两者间的水平度。横向每隔1.5m左右做一个标志块,将作为粘贴厚度的依据,以便在铺贴过程中随时检查表面的平整度。Thetilingislaidfromtoptobottomorfromrighttoleft.Usually,itisheldbythelefthand,whichfacilitatestheworkandprovidefullviewaswell.Oncearowoftilesisputtoplace,arectificationwithalongrodisrequired.Thosewhichareabovethesignalpieceshallbetappeddown.Thosewhicharelowerthanthesignalpieceshallberemovedandre-plastered.Itisprohibitedtoapplyplasteringdirectlyatthejoint,asitmayresultintobulge.Particularattentionshallbepaidwhileinterconnectingwithanotherrowofceramicstoensuretheyareflushedwithoneanother.Incasetherearedeviationsinspecificationorphysicaldimensionamongtiles,itisrequiredtoperformtimelyadjustmenttokeeptheyareunified.Therowaboveallshallbetiledinlineandtreatedwithtilesofarcincasethereisnobatten.156
