Background
With the concern of engineering quality, the resiliometer has become one of the detection and analysis means of engineering accidents, and is becoming a reliable monitoring tool in engineering quality control and building use.
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).
During measurement, the resiliometer needs to be kept vertical to the surface of a building to be measured, if the resiliometer is in a non-horizontal and vertical state, the measurement result needs to be converted and adjusted according to the incident angle, and otherwise, the measurement error is large or the measurement is inaccurate. The existing building surface is mostly a horizontal plane or a vertical plane, and in the existing measuring device, whether the resiliometer is vertical to the building surface can be judged only according to naked eyes, so that the measuring result is inaccurate.
