Description

Anti-slip sheath structure of concrete resiliometer

Technical Field

The utility model relates to the technical field of concrete resiliometers, in particular to an anti-slip sheath structure of a concrete resiliometer.

Background

The concrete resiliometer is a detection device, is suitable for detecting the strength of common building components, bridges and various concrete components (plates, beams, columns and bridges), and has the main technical index of impact function; spring impact tension spring rigidity; a spring hammer stroke; the maximum static friction force of the pointer system and the right drilling rate are averaged. The concrete resiliometer drives the spring hammer by a spring and the elastic hammer drives the pointer to rebound and indicates the rebound distance by the restoring force of instantaneous elastic deformation generated by the impact of the impact rod on the concrete surface. The compressive strength of concrete is estimated by taking the rebound value (the ratio of the rebound distance to the distance of the hammer to the striking rod before impact, calculated as a percentage) as one of the indexes related to the compressive strength of concrete.

Rebound is one of the most common methods for measuring the compressive strength of concrete, and the rebound apparatus is used by taking care of the posture of holding the rebound apparatus during use, holding the middle of the rebound apparatus with one hand and straightening it, holding the tail of the apparatus with the other hand, and then applying pressure to the apparatus. When in operation, the axis direction of the resiliometer is always vertical to the surface of the detection member, and the force is evenly and slowly applied, and the resiliometer is slowly pushed and rapidly read. In order to improve the working efficiency, a detector takes a plurality of resiliometers to detect, and only the tail part of the resiliometers on the market is provided with a sheath at present, because one hand is needed to exert force on the tail part in the operation process of the resiliometers, the other hand is needed to hold the middle part for auxiliary force, but the middle part is a metal shell of the resiliometers, and the hand often sweats in the operation process of the resiliometers, so that the auxiliary force effect is not obvious although the one hand holds the middle part of the resiliometers, the main force is the tail part force, and the hand and the arm which exert force for a long time often can be ache; in addition, in the long-time detection working process, the concrete resiliometer is often not vertical to the wall surface during detection, and the detection result is influenced, so that improvement is needed.
