混凝土预制构件的质量好坏,直接影响到人民生命财产的安全和建筑物的使用寿命.但是,在混凝土预制构件质量检测和质量评定中,由于有关标准本身有些内容不够明确,各地对有关标准的理解和执行存在着较大的差异,以致影响了构件质量等级的评定与划分.本文就此问题作些探讨.一、检测内容及检测指标现有规范规定,评定混凝土预制构件质量时应检测三个内容共19项指标。但规范对19项指标没有作出主次之分,因而给产品质量等级的评定和划分带来了一定的困难.我们认为19项检测指标应相对划分为主要指标和一般指标:
The quality of concrete prefabricated components directly affects the safety of life and property of people and the service life of buildings. However, in the quality inspection and quality assessment of prefabricated concrete components, due to the fact that some of the relevant standards themselves are not clear enough, the relevant standards There is a big difference in understanding and implementation, which affects the evaluation and division of component quality grades. This article will discuss this issue. First, the current content of testing and detection indicators specification requirements, to assess the quality of concrete prefabricated components should be detected three Content A total of 19 indicators. However, the norm has not made major or minor distinctions for the 19 indicators, which has brought certain difficulties to the assessment and classification of product quality levels. We believe that the 19 detection indicators should be relatively divided into the main indicators and general indicators:
