Description

Technical Field

[0001] This utility model relates to the field of concrete rebound hammer technology, and specifically to a positioning device for concrete rebound detection. Background Technology

[0002] A concrete rebound hammer is a testing device suitable for testing the strength of general building components, bridges, and various concrete components (slabs, beams, columns, and cable trays). Its main technical indicators include impact capability; spring stiffness; hammer stroke; maximum static friction force and average stiffness of the pointer system. Throughout the operation of the rebound hammer, attention should be paid to the grip posture. One hand should hold the middle of the hammer for stability; the other hand should hold the tail of the instrument to apply pressure and also assist in maintaining stability.

[0003] Currently, most methods of using rebound hammers involve manual handheld operation and visual adjustment of measurement points. However, manual operation cannot guarantee that the concrete rebound hammer is always perpendicular to the plane being tested, leading to errors in the measurement data. Therefore, a positioning device is needed during measurement. However, existing positioning devices have low flexibility and are troublesome to disassemble. Therefore, there is an urgent need for a positioning device for concrete rebound testing to overcome the above-mentioned shortcomings. Utility Model Content
