济南某商业办公楼为框架-核心筒结构，梁柱混凝土采用不同的强度等级，因施工过程中未按照规范要求在不同强度等级混凝土结合面处铺设钢丝网，模板拆除后发现梁柱混凝土结合面处存在明显分界线，为保证结合面质量，采用超声法对结合面工程质量进行检测。超声法检测时应使超声波斜穿结合面并记录各测点声参量值，运用统计法判断声参量异常点，并结合钻芯法进行验证。

Jinan,a commercial office building for framework-core structure,the beam column concrete adopt the different intensity grade.Upaving steel wire mesh at the joint surface in accordance with technical specification,the obvious dividing line was found at the joint surface of concrete beams after template removal.In order to ensure the quality of the joint surface, testing the quality of joints by ultrasonic method.Ultrasonic detection points should be inclined the surface of joints and record various acoustic parameters.Judging the outliers of acoustic parameters and was verified by the core drilling method.
