Zusammenfassung:The invention discloses a beam plate type structure steel bar corrosion detection method and a detection device. The detection device is mainly composed of a lifting type support, a sliding groove, a sliding block, a winch, a detection unit and a data analysis and processing unit. According to the detection method, the steel bar corrosion rate is obtained by establishing the quantitative relation between the steel bar corrosion rate and the deformation amount corresponding to the position of the center section line of the steel bar on the surface of the beam-slab structure and measuring the deformation amount corresponding to the position of the center section line of the steel bar on the surface of the beam-slab structure through the detection device; therefore, the corrosion damage of the reinforced concrete structure can be detected efficiently, quickly and nondestructively. 本发明公开了一种梁板式结构钢筋锈蚀检测方法及检测装置,此检测装置主要由升降式支架、滑槽、滑块、卷扬机、检测单元和数据分析处理单元构成。本发明的检测方法通过建立钢筋锈蚀率与梁板式结构表面钢筋中心剖线位置对应的变形量的量化关系,通过检测装置测得梁板式结构表面钢筋中心剖线
