Description
Technical Field

It has not only become one of the means of detection and analysis of engineering accidents, but also is becoming a reliable monitoring tool for engineering quality control and building use.
[0003] In the wall compressive strength testing device, the rebound tester is one of the indispensable tools. The basic principle of the rebound tester is to use a spring to drive a heavy hammer, which hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, such as Figure 6 , and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance. The instrument displays the maximum rebound distance of the heavy hammer in the name of rebound value (the ratio of the maximum rebound distance to the initial length of the spring).
[0004] In the prior art, the rebound tester usually requires the user to hold the body of the rebound tester and make the head of the impact rod perpendicular to the test surface. The test process requires slow pressure, rapid reset, and accurate reading. The entire operation process is short and requires high operator skills. If the operation is not standardized, it is easy to cause measurement errors.
