Description

Technical Field

[0001] The utility model relates to the technical field of concrete rebound test hammer equipment, in particular to a concrete rebound test hammer for concrete testing. Background Art

[0002] A concrete rebound test hammer is a device used to test concrete strength. It uses a spring-driven hammer to strike the concrete surface with constant kinetic energy, causing local deformation and absorbing energy. Part of this energy is converted into the hammer's rebound kinetic energy. When the hammer rebounds to its maximum distance, the hammer displays the rebound value, which is the ratio of the maximum rebound distance to the initial spring length. This value reflects the concrete's hardness and can be used to deduce its compressive strength.

[0003] In addition, after the concrete rebound test hammer is used, since the head of the concrete rebound test hammer is not rigidly connected to the equipment, it is easily affected by external collisions after use, which may affect the equipment during subsequent testing and use. In order to reduce the impact of the equipment's use, the end of the equipment needs to be protected. Utility Model Content
