浅谈钢管混凝土柱柱芯混凝土质量检测

Discussion for the concrete quality control of concrete-filled steel tubular structure

钢管混凝土柱因其承载力高,广泛应用于超高层、大跨度建筑物中。钢管混凝土柱柱芯混凝土质量对其受力有着较大的影响,因此,加强柱芯混凝土质量控制尤为重要。目前对柱芯混凝土质量的检验方法有敲击法、钻芯法和超声波法等。本文通过比较这几种检测方法的利弊,认为超声波法对于柱芯混凝土质量检测具有较好的适用性。

Because of the high loadsupporting,the concrete-filled steel tubular structure is used widely in superhigh and longspan building. The quality of concrete-filled has a great influence on mechanical property of the structure. For this reason,it is important to control the quality of concrete-filled. The inspections of concrete defects are strike,drilling and ultrasonic methods. By comparison with advantages and disadvantages of the three inspection methods,the ultrasonic methods has a good suitability for inspection of concrete defects.
