The basic principle of the rebound tester is that a spring drives a heavy hammer, the heavy hammer impacts an impact rod which is vertically contacted with the surface of concrete with constant kinetic energy, so that the local concrete deforms and absorbs a part of energy, the other part of energy is converted into rebound kinetic energy of the heavy hammer, when the rebound kinetic energy is completely converted into potential energy, the rebound of the heavy hammer reaches the maximum distance, and the maximum rebound distance of the heavy hammer is displayed by the tester in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).
The conventional concrete resiliometer comprises a resiliometer body and a detection rod, and in the whole process of operating the resiliometer, the middle part of the resiliometer body is held by one hand to play a role in righting; the other hand is used for pressing the tail part of the resiliometer body to apply pressure to the instrument and also plays a role in assisting in righting. The operation of the resiliometer is as follows: ensuring that the axis of the resiliometer is always vertical to the concrete test surface, exerting force uniformly and slowly, and righting to align to the test surface; slow advance, fast reading. However, when the concrete strength is detected, the operator holds the concrete rebound apparatus by hand to detect the concrete member, so that it is difficult to ensure that the axis of the concrete rebound apparatus is always perpendicular to the test surface of the concrete member, and a large human error is generated during detection.
Therefore, how to design a concrete rebound instrument with simple operation and small detection error is a problem which needs to be solved urgently at present.
