Description

Nondestructive testing concrete intensity device

Technical Field

The utility model relates to a resiliometer auxiliary assembly field particularly, relates to a nondestructive test concrete intensity device.

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).

The resiliometer is a device for measuring the strength of reinforced concrete in the production process of reinforced concrete, and is widely used in the field of building construction. When the concrete resiliometer is adopted, an operator aligns an elastic striking rod of the concrete resiliometer to the surface of reinforced concrete to be detected, an elastic striking hammer impacts the tension of the tension spring by means of elastic striking, the elastic striking rod rebounds to drive the pointer sliding block to move backwards, scales indicated by a graduated scale of the resiliometer are rebound values, the rebound values are dependent on impact energy and related rebound energy, and the rebound energy is mainly dependent on the elastic-plastic property of the detected concrete.

The strength of the reinforced concrete is measured, the axis of the concrete resiliometer is difficult to be perpendicular to the concrete testing surface all the time when manual operation is carried out for detection, the detection accuracy is poor, the use is inconvenient, and particularly when force is applied by two hands, the resiliometer and the concrete testing surface cannot be strictly guaranteed to be perpendicular all the time, so that the result is inaccurate.
