Description

Technical Field

[0001] The utility model relates to the technical field of rebound testers, in particular to a concrete rebound tester for construction engineering supervision. Background Art

[0002] The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance. The instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

[0003] During the use of the existing concrete rebound test hammer for construction engineering supervision, although it can detect concrete, it cannot handle dust during the detection process, resulting in clogging of the equipment during use, causing the equipment to be unable to measure accurately. When testing concrete, the staff needs to hold the equipment and press the concrete, causing the equipment to fall from the hand during the pressing process, causing damage to the equipment, thereby reducing the service life of the rebound test hammer, reducing the accuracy and service life of the traditional construction rebound test hammer, and therefore a concrete rebound test hammer for construction engineering supervision is proposed.
