Abstract

The invention discloses a clamping type concrete damage detection device. The detection device comprises a sensor and a clamping jig, the sensor is installed on the clamping jig, and a concrete test piece is clamped through the clamping jig to enable the sensor to be tightly attached to a surface of the concrete test piece so as to achieve the detection of the concrete test piece. According to theinvention, the sensor is repeatedly used, the sensor can be quickly assembled and disassembled, and the wiring complexity is greatly reduced.

Description

technical field [0001] The invention relates to civil engineering, intelligent material technology and health monitoring technology, in particular to a concrete damage detection device. Background technique [0002] Piezoelectric ceramics have become an important carrier in the field of structural health monitoring due to their unique direct piezoelectric effect and inverse piezoelectric effect. It is widely used in concrete structures because of its wide frequency response range, fast response, easy processing, and low price. In recent years, detection technology based on piezoelectric ceramics has developed rapidly. For the detection of concrete, the piezoelectric ceramic sensor needs to be bonded to the concrete specimen, which is difficult to remove and reuse, which increases the cost of detection technology. [0003] The better the performance of piezoelectric ceramic sensors, the higher the cost, and the detection of concrete specimens requires a large number of piez...
