Description

Technical Field

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

[0002] Concrete is mainly used in the construction industry, which requires a large amount of concrete. The strength of concrete plays a crucial role in the life and safety of the building. Before construction, in order to ensure the strength of the concrete, strength testing is required. In short, strength testing is to test the pressure of concrete blocks per unit volume to see whether the strength meets the standard.

[0003] When performing strength testing, the concrete block needs to be placed directly under the stamping structure so that the concrete block is evenly stressed, and the limiter needs to be aligned. However, in actual use, the limiter structure is not removed after use, so that the structure for adjusting the position of the concrete block is damaged by pressure and cannot be automatically removed. Therefore, those skilled in the art provide a concrete strength testing device to solve the problem. Utility Model Content
