摘要
钢筋保护层厚度对结构的安全性、耐久性有很重要的影响,《混凝土结构工程施工质量验收规范》(GB 50204-2015)中对其检测作了详细规定,其中规定了对每根钢筋应选择有代表性的不同部位测量3点取平均值,但未明确规定如何选择该3个测点。文章结合工程实例,分析了结构实体构件中不同测点处的钢筋保护层厚度检测值的变化,并给出若干建议。
The thickness of protective layer of reinforcement has a very important impact on the safety and durability of structures.The“Code for quality acceptance of concrete structure construction”(GB 50204-2015)has made detailed provisions,which stipulates that three representative different parts of each steel bar should be selected to measure the average value of three points,but it is not clear how to select the three measuring points.Combined with the engineering example,this paper analyzes the difference of the detection value of the reinforcement cover thickness at different measuring points in the structural entity component,and gives some suggestions.
