水泥砂浆楼地面施工技术交底 水泥砂浆楼地面施工技术交底提要:铺水泥砂浆压头遍:紧跟贴灰饼冲进铺水泥砂浆,配合比为水泥:砂=1:2,稠度应小于,用木抹子赶铺拍实,木杠按铁饼冲筋标高刮平 水泥砂浆楼地面施工技术交底 1、施工步骤 (1)基层清理:地面基层,地墙相交的墙面,踢脚线处的粘杂物清理干净,影响面层厚度的凸出部位应剔除平整。 (2)洒水润湿:在施工前一天洒水润湿基层。 抹踢脚板:有墙面抹灰层的踢脚板,底层砂浆和面层砂浆分两次抹成。 踢脚板抹底层水泥砂浆:清理基层,洒水润湿后,按标高线向下量尺至踢脚板标高,拉通线确定底灰厚度,套方,贴灰饼,抹1:3水泥砂浆,刮板刮平,搓平整,扫毛浇水养护。 踢脚板抹面层砂浆:底层砂浆抹好,硬化后,拉线贴粘靠尺板,抹1:2水泥砂浆,抹子压抹上灰后用刮板紧贴靠尺垂直地面刮平,用铁抹子压光,阴阳脚、踢脚板上口,用角抹子溜直压光。 (3)刷素水泥浆结合层:在垫层或楼板基层上均匀洒水后,在撒水泥面,经扫涂形成均匀的水泥浆粘结层,随刷随铺水泥砂浆。 (4)冲筋贴灰饼:根据+50表高水平线,在地面四周做灰饼。大房间增加冲筋。 (5)铺水泥砂浆压头遍:紧跟贴灰饼冲进铺水泥砂浆,配合比为水泥:砂=1:2,稠度应小于,用木抹子赶铺拍实,木杠按铁饼冲筋标高刮平,上木抹子搓平,待反水后略撒1:1干水泥砂子面,吸水后铁抹溜平。上述操作均在水泥砂浆初凝前进行。 第二遍雅光:在压平头遍后,水泥砂浆凝结,人踩上去有脚印但不下陷时,用铁抹子压第二遍。要求不漏压,平而出光。 第三遍压光:水泥砂浆终凝前进行第三遍压光,人踩上去稍有脚印,抹子抹上去不再有抹子纹时,用铁抹自把第二遍压光留下的抹子纹压平、压实、压光,达到交活的程度。每一遍完后都要自检。 (6)养护:地面压光交活后24小时,铺锯末撒水养护并保持湿润,养护时间不少于15天。养护期间不允许压重物和碰撞。 2、质量标准 (1)保证项目 1)水泥、砂的材质必须符合设计要求和施工及验收规范的规定。 2)砂浆配合必要准确。 3)地面面层与基层的结合必须牢固无空鼓。 (2)基本项目 1)表面洁净,无裂纹、脱皮、麻面和起砂等现象。 2)踢脚板高度一致,出墙厚度均匀与墙面结合牢固,局部有空鼓长度不大于200mm,且在一个检查范围内不多于两处。 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness.
