14、东省混凝土结构实体检验技术导则(试行)混凝土结构工程施工质量验收规范GB50204四、检测前的准备1、检测前应要求施工单位做回弹法混凝土抗压强度检测。2、收集资料检测前应查有关的监理记录和设计图纸,收集下列资料:结构或构件名称、外形尺寸、数量及混凝土强度等级;水泥品种、强度等级、安定性、厂名;砂、石种类、粒径;外加剂或掺合料品种、掺量;混凝土配合比等;施工时材料计量情况,模板、浇筑、养护及成型日期等。3、组织学习有关的规程,明确具体做法。4、对照回弹仪的使用说明书学习回弹仪的使用方法;检查回弹仪的合格证、中国计量器具制造许可证标志CMC及许可证号。5、熟悉施工图,选定要回弹的构件,并将构件名和

15、构件所对应的轴线号,写在记录纸上;或由现场选择要进行回弹的构件,然后对照图纸,将构件名和构件所对应轴线号,写在记录纸上。6、工具准备:回弹仪、冲击钻(配12钻头)、2%酚酞酒精溶液、滴管、深度测量尺、记录纸和笔、粉笔、1m杠尺、2m梯子、手砂轮、线轴。五、检测的具体做法测量混凝土强度按照回弹法检测混凝土抗压强度技术规程技 术要求进行检测。检测时,回弹仪的轴线应始终垂直于结构或构件的混凝土面,缓慢施压,准确读数,快速复位。测点宜在测区范围内均匀分布,相邻两测点的净距不宜小于20mm,测点距外露钢筋、预埋件的距离不宜小于30mm。测点不应在气孔或外露石子上,同一测点只应弹击一次。每一测区应记取16

16、个回弹值,每一测点的回弹值读数估读至1。1、回弹法混凝土抗压强度检测应在混凝土施工完成28d后,验收前进行。2、检测数量监理单位应依据回弹法检测混凝土抗压强度技术规程(JGJ/T232011)的规定选择主体结构中的梁、墙、柱等重要受力构件,每个强度等级至少抽取同类构件数量的2%,且每个强度等级不少于5件。3、检测方式监理单位应按单个结构和构件对泵送混凝土抗压强度进行检测。4、回弹仪的使用注意事项回弹仪应按规程要求进行检定和保养;开始检测前应在洛氏硬度HRC为602的钢砧上进行弹击,回弹仪的率定值应为802;弹击次数超过2000应进行常规保养,并在洛氏硬度HRC为602的钢砧上进行弹击,回弹仪的

17、率定值应为802;新回弹仪启用前;检定有效期超过半年;累计弹击次数超过6000次;进行常规保养后在钢砧上率定值不合格;遭受严重撞击或其他损害等情况,应将回弹仪送检定单位检定。5、检测方法每一结构和构件测区数为十个;相邻两测区的间距应控制在2米以内,测区离构件端部或施工逢边缘的距离不宜大于0.5m,且不宜小于0.2m;测区应选在使回弹仪处于水平方向检测混凝土建筑侧面;测区宜选在构件的两个对称可侧面上,也可以选在一个可测面上,且应均匀分布。在构件的重要部位及薄弱部位必须布置测区,并应避开预埋件;测区的面积不宜大于0.04;检测面应为混凝土表面,并应清洁、平整,不应有疏松层、浮浆、油垢、涂层以及蜂窝

18、、麻面,必要时可以用砂轮清除疏松层和杂物,且不应有残留的粉末或碎屑;对弹击时产生颤动的薄壁、小型构件应进行固定;结果或构件的侧区应标有清晰的编号,必要时应在记录纸上描述侧区布置示意图和外观质量情况。6、回弹值测量:检测时,回弹仪的轴线应始终垂直于结构或构件的混凝土检测面,缓慢施压,准确读数,快速复位。测点宜在测区范围内均匀分布,相邻两测点的静距不宜小于20;测点距外露钢筋、预埋件的距离不宜小于30。测点不应在气孔或外露石子上,同一测点只应弹击一次。每一测区应记取16个回弹值,每一测区的回弹值估读至1。7、碳化深度值测量:回弹值测量完毕后,应在有代表性的位置上测量碳化深度值,测点表不应小于构件测

19、区数的30%,取其平均值为该构件每测区的碳化深度值。当碳化深度值极差大于2.0时,应在每一测区测量碳化深度值。碳化深度值测量,可采用适当的工具在测区表面形成直径约15的孔洞,其深度应大于混凝土的碳化深度值。孔洞中的粉末和碎屑应除净,并不得用水擦洗。同时,应采用浓度为2%的酚酞酒精溶液滴在孔洞内壁的边缘处,当已碳化与未碳化界线清楚时,再用深度测量工具测量已碳化与未碳化混凝土交界面到混土表面的垂直距离,测量不应少于3次,取其平均值。每次读数精确至0.5。8、将记录纸上记录的回弹值和碳化深度值,填写在附表1、附表2中。附表1和附表2中其它内容应根据工程实际情况填写。六、数据处理为了提高数据处理效率,

20、防止计算错误,数据处理可先根据编制计算程序,由计算机软件完成。七、安全注意事项回弹人员应穿防滑鞋,登梯子高处干活时应有人扶梯子,防止摔伤。认真落实各项安全防护措施。Provide training and the introduction of a XX in XX city XX special childrens Rehabilitation Center City Federation of the disabled and all sectors of the community concern and support in 2013 December was established,
