Description

Pressure resiliometer

Technical Field

The utility model relates to a building check out test set field, more specifically says that it relates to a pressure resiliometer.

Background

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).

Chinese patent No. CN205593869U discloses a novel high-strength concrete resiliometer, which comprises a shell, a central guide rod, a bounce hammer, a bounce tension spring, a bounce rod, a trigger mechanism, a button structure and a pointer mechanism, wherein when the resiliometer rebounds, the bounce rod is aligned to the surface of the concrete to be tested and pressed down, the rebounding instrument bouncing rod continuously retracts into the instrument shell, because the hook is already hooked on the bouncing hammer at the moment, as the rebounding rod retracts into the instrument, the bouncing tension spring is stretched, when reaching a certain stretching length, the top of the hook is contacted with the adjusting bolt, the hook spring is compressed, the hook is suddenly separated from the elastic hammer, the elastic hammer impacts the surface of the concrete through the elastic rod along the central guide rod, then the elastic hammer is rebounded, the elastic hammer drives the pointer sliding block to move through the pointer spring piece, the pointer on the pointer sliding block indicates the moving distance, and the whole working process of the resiliometer is achieved.

Although this resiliometer can carry out effectual detection to the concrete surface, in the measurement process, when the tapping rod withdraws in to the casing, can be to the casing striking, the user grips on the casing, and the arm can produce strong vibrations, can produce the damage to user's arm, can't continue to use the resiliometer after the user uses for a long time to can influence the work efficiency of resiliometer, consequently, need improve it.
