[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementing materials, aggregates and water in a certain proportion, stirred and vibrated into shape, and cured under certain conditions. Before using concrete, its compressive strength needs to be tested. At present, there are many methods for testing the compressive strength of concrete. For the testing of the compressive strength of concrete, methods such as rebound method, ultrasonic rebound comprehensive method, post-installation pull-out method or core drilling method can be used. When the rebound method is used for testing, the concrete is first made into a concrete slab of a certain thickness, and multiple points on the concrete slab are tested by a rebound tester. When using a rebound tester for testing in the prior art, most of the rebound testers are manually operated for testing. Manual testing is difficult to ensure that the rebound tester and the concrete slab to be tested are always in a vertical state, which leads to inaccurate test results. In addition, it is inconvenient to record data during manual testing, resulting in low detection efficiency. Therefore, a concrete quality detection device for construction is designed to meet the use requirements, and it meets the requirements of utility models after retrieval. Utility Model Content
