Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete coagulation quality detection device. Background Art

[0002] The rebound method is generally used to detect the compressive strength of concrete coagulation quality. The rebound method is a method of indirectly inferring the compressive strength of concrete by using the curve relationship between the surface hardness of concrete and the compressive strength of concrete. The rebound hammer used to measure the coagulation strength is a direct-shot hammer-type rebound hammer. During the impact process, the impact hammer impacts the impact rod with the help of the tension of the impact spring and then rebounds, driving the pointer slider to move backward. The scale indicated on the rebound hammer scale is the rebound value. The size of the rebound value depends on the rebound energy related to the impact energy, and the rebound energy depends on the elastic-plastic properties of the concrete being tested. The lower the strength of the concrete, the greater the plastic deformation will be, and the greater the plastic deformation, the smaller the rebound energy, and thus the smaller the rebound value, and vice versa.

[0003] When testing concrete, the existing concrete coagulation quality detection device usually requires people to press the surface of the concrete with a handheld rebound hammer for detection. This is inconvenient for people to locate different positions on the concrete surface, and the handheld rebound hammer cannot maintain the verticality between the instrument and the concrete surface, which will affect the accuracy of the detection. The instrument is also inconvenient to carry and move. In order to solve the shortcomings of the existing technology, we propose a concrete coagulation quality detection device.
