Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an engineering detection area, concretely relates to can improve resiliometer of calibration degree of accuracy.
[ background of the invention ]
In the actual engineering construction process, the resilience method is often adopted to detect the strength of the engineering structure concrete. The rebound method has the advantages of light instrument, simple operation, no damage to the structure, repeatable detection and the like, and utilizes the rebound instrument to detect the surface hardness of the concrete to calculate the strength of the concrete. The basic principle of the resiliometer is that a spring drives a heavy hammer, the heavy hammer impacts a striking 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 instrument in the name of rebound value (the ratio of the maximum rebound distance to the initial length of the spring).
Calibration tests should be performed for resiliometer calibration or maintenance as specified by current standards. The resiliometer calibration test should be carried out in four directions, and before each direction is flicked, the flicking rod should be rotated by 90 degrees. However, at present, related accessories of the original resiliometer do not have the function of accurately measuring the rotation angle of the rebound rod in the calibration test, the rotation angle of the rebound rod in the calibration test can be completed only by depending on the experience of a tester, and the test error is large.
