钢筋保护层厚度测量仪用于检测现有钢筋混凝土或新建钢筋混凝土内部钢筋直径、位置、钢筋分布及钢筋的混凝土保护层厚度,其计量性能对建筑工程的质量有着直接的重要影响,因此建筑工程实验室会定期将所用的钢筋保护层厚度测量仪送至计量技术机构进行校准,以确定其示值误差保持在允许的范围,而开展校准必须评定测量结果的不确定度。本文从测量方法概述、建立数学模型、不确定度来源分析和评定等几个方面进行了分析。
Reinforced cover thickness gauge used to detect the existing reinforced concrete or new reinforced concrete internal reinforcement diameter, location, reinforcement distribution and reinforced concrete cover thickness, the measurement of the quality of construction has a direct and important impact, the construction The laboratory will regularly use the thickness of the protective layer measuring instrument used to measure the technical institutions to be calibrated to ensure that the indication error is maintained within the allowable range, and calibration must be assessed to measure the uncertainty of the results. This article has carried on the analysis from the measuring method outline, the establishment mathematics model, the source of the uncertainty analysis and the appraisal.
