某车库框架梁钢筋锈蚀检测鉴定

Test and Supervision of Corrosion of Steel Bars of Concrete Frame Beam in an Underground Garage

由于自身因素和环境因素的共同影响,混凝土结构易产生钢筋锈蚀之类的耐久性问题。论文结合某车库地下2层框架梁的钢筋锈蚀情况从外观质量、保护层厚度、现场环境等进行了检测鉴定,结果表明框架梁的钢筋锈蚀目前未对结构构件承载力产生影响,又从构件自身因素和环境因素分析了钢筋锈蚀的原因,提出处理建议,为其他类似混凝土结构的耐久性研究提供工程方面的依据。

The concrete structures are prone to durability problem such as the corrosion of the steel bars due to the influence of the component factor and the environmental factor.The paper describes the appearance quality test,the concrete cover depth,the environmental survey and supervision of the corrosion of the steel bars of concrete frame beams on the second floor of an underground garage based on the engineering project.The results show that the corrosion of steel bars has no effect on the bearing capacity of the structural members at present.The component factor and the environmental factor contribute to the steel corrosion.The proposal and the method are put forward.The paper aims to provide the engineering basis for research on durability of similar concrete structure projects.
