Description

Concrete resiliometer

Technical Field

The utility model belongs to the technical field of the concrete detecting instrument, concretely relates to concrete resiliometer.

Background

The concrete resiliometer uses a spring to drive the elastic hammer and utilizes the restoring force of instantaneous elastic deformation produced by elastic striking of the elastic striking rod on the concrete surface to make the elastic hammer drive the pointer to rebound and indicate the rebound distance. The compression strength of concrete is estimated by using a rebound value (a ratio of a rebound distance to a distance between a hammer and a striking rod before impact in percentage) as one of indexes related to the compression strength of concrete. The shell of resiliometer is held to the staff for the striking rod is contradicted perpendicularly on the concrete member, and in operation process, because the resiliometer shell is cylindricly, is unfavorable for exerting pressure to the striking rod, is difficult to guarantee moreover that the axis of concrete resiliometer and the test surface of concrete member remain throughout perpendicularly, not only influences the accuracy that detects, has consumed the time moreover.
