The invention discloses an electromagnetic-driven lossless resiliometer. The electromagnetic-driven lossless resiliometer includes a resiliometer housing with a cavity, a handle and a tube, wherein a fixed block and a movable block; a strike hammer is embedded in the moable block; the front end edge of the movable block fits a trigger; and a coil which is communicated with a power supply is wound around the fixed block. The electromagnetic-driven lossless resiliometer uses magnetic repulsion to replace the spring pressure of a traditional resiliometer as the impact power supply for the strike hammer, and takes the magnetic repulsion to replace the tension of an extension spring of the traditional resiliometer as a rebound value detection mechanism, and has the advantages of long service life and high accuracy compared with the traditional spring type resiliometer.
Description
technical field [0001] The invention belongs to the technical field of concrete nondestructive testing equipment, and relates to an electromagnetically driven nondestructive rebound rebound instrument and a measuring method. Background technique [0002] In civil engineering testing, the non-destructive testing of the strength of existing reinforced concrete structures is a very important testing item, and the rebound tester is the most important instrument and equipment in testing the compressive strength of concrete. The rebound hammer has the characteristics of simple operation and portability, and is very suitable for on-site non-destructive testing of building structures. Although a series of instruments for non-destructive testing of concrete strength have been developed at home and abroad for a long time, the rebound hammer still maintains its leading position in the field of non-destructive testing of concrete compressive strength. [0003] The current rebound hamme...
