Description

Mechanical digital resiliometer

Technical Field

The utility model relates to the technical field of building measurement equipment, in particular to a mechanical digital resiliometer.

Background

The strength value of the concrete is the maximum stress which the concrete can bear under certain stress state and working condition. To accurately measure the strength of concrete, the concrete test block must be loaded to the failure limit, and the test piece is broken after the test value is obtained. The nondestructive testing method of the concrete strength of the structure is to obtain the destructive stress value without damaging the structure and the components, so that one or more stress functional values related to the concrete strength can be found, the stress functional values of the concrete are tested without damage, the indirect calculation value is actually an indirect calculation value, the degree of coincidence between the indirect calculation value and the actual strength of the concrete depends on the correlation between the physical quantity and the concrete strength, and the nondestructive testing technology of the concrete is usually provided with a rebound method for measuring the strength.

The resiliometer works according to the basic principle of the rebound method. The rebound method is to use a weight driven by a spring to bounce the surface of concrete by a bouncing rod and a dowel bar, and to measure the rebound distance of the weight, and to estimate the strength of the concrete by taking the ratio of the rebound distance of the rebound value to the initial length of the spring as an index related to the strength. Although other nondestructive testing methods are continuously appeared, the method has the advantages of simple instrument structure, simple and convenient method, better correlation between the test value and the concrete strength under certain conditions, low test cost and the like, so far, the method does not lose the superiority of field application, and is accepted by the international academy as one of the basic methods of nondestructive testing of the concrete.

When the resiliometer is used for testing the building wall, the resiliometer is usually manually operated, and in the use process of the resiliometer, the resiliometer is required to be always kept perpendicular to the surface of the concrete, otherwise, the test can obtain an error detection result, and when the resiliometer is manually operated, whether the resiliometer is kept perpendicular to the surface of the concrete is generally confirmed by visual inspection and hand feeling, and the resiliometer confirmed by the mode has a larger error in perpendicularity with the surface of the concrete, so that the measurement result of the resiliometer is finally influenced.
