Concrete resiliometer

Technical Field

The utility model belongs to the technical field of the technique of measurement concrete intensity and specifically relates to a concrete resiliometer is related to.

Background

The concrete resiliometer is characterized in that a spring is used for driving an elastic hammer, and the elastic hammer drives a pointer to rebound and indicates the rebound distance through the restoring force of instantaneous elastic deformation generated by the elastic striking of a striking rod on the surface of concrete. 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 concrete resiliometer generally detects the strength of building elements, bridges and various concrete elements (plates, beams, columns and bridges), and in the detection process, the concrete resiliometer generally needs to be vertically and tightly abutted against a wall surface, so that the detection precision of concrete is improved.

Patent publication number is CN 207336207U's chinese patent, a concrete resiliometer is proposed, belong to concrete strength detecting instrument technical field, including resiliometer body and measuring bar, the outer wall cover of resiliometer body is equipped with the leading truck, the leading truck is including cup jointing the mounting on resiliometer body lateral wall, the mounting passes through clamping component to be fixed on the resiliometer body, clamping component and mounting threaded connection, the mounting is close to a side vertical surface of measuring bar and is fixed with the telescopic link, the axis of telescopic link is parallel with the axis of resiliometer, one side fixedly connected with that the telescopic link is far away from the mounting can make the fender ring that the measuring bar passed, the side of fender ring is perpendicular with the axis of telescopic link, keep off the extension range that the ring is located the measuring bar, the extension range of telescopic link is greater than the extension range of measuring.

The above prior art solutions have the following drawbacks: when detecting, with the perpendicular butt back of concrete resiliometer on the wall, keep off the ring and support tightly on the wall to conveniently keep concrete resiliometer and wall to keep perpendicular, but when the wall unevenness, perhaps when measuring cylindric concrete, keep off the ring this moment and not paste completely and lean on the wall body, thereby be difficult to keep concrete resiliometer perpendicular with the wall, influence measuring precision easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a concrete resiliometer convenient to keep concrete resiliometer to keep perpendicular with the wall body to improve concrete detection precision.

The utility model discloses a can realize through following technical scheme:
