Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete's detection, specifically relates to a concrete hardness detection device. BACKGROUND

[0002] Concrete is an indispensable building material in modern construction engineering, which is made of multiple components mixed in specific proportions. These components mainly include cementitious materials such as cement, granular aggregates such as sand and gravel, water, and additional admixtures and additives if necessary. These materials are proportioned and uniformly mixed to form a homogeneous mixture. Subsequently, through the process of compaction molding and curing hardening, it is finally transformed into a solid artificial stone. Concrete is widely used because it has several notable advantages: first, its raw materials are widely available and easy to obtain; second, it is relatively low in cost and economical; finally, its production process is relatively simple and suitable for large-scale production. Due to these characteristics, the use of concrete in construction engineering is increasing. However, the quality of concrete is directly related to the safety, durability, and service life of the building. Therefore, it is particularly important to strictly test the concrete. By testing the concrete, defects that may occur during the construction process, such as cracks, voids, and insufficient strength, can be detected in a timely manner. This not only prevents potential safety accidents, but also greatly reduces the cost of later maintenance and reinforcement, thereby ensuring the long-term stability and safety of the building.

[0003] For concrete testing, the hardness detection of concrete is of great significance to ensure the safety and durability of the building. In order to detect the hardness of concrete, the concrete sample needs to be processed into a specific shape of test block according to the established size standard. Then place the concrete test block on the hardness detection device, and measure the hardness value of the concrete test block by operating the hardness detection device to apply pressure to the test block, so as to determine whether the concrete material meets the requirements. However, during the process of applying pressure to the concrete test block by the hardness detection device, as the pressure applied to the concrete test block gradually increases, the test block will start to crack and eventually break, resulting in the scattering of concrete fragments and debris. These debris not only scatter in various parts of the hardness detection device, but also pose a safety threat to the operator, causing injury. In addition, after the detection is completed, the hardness detection device must be thoroughly cleaned to remove the scattered debris. This cleaning process not only consumes time and affects the continuity of the detection work, but also increases the workload of the detection personnel. Therefore, the concrete hardness detection method urgently needs to be improved in practical application to prevent the scattering of debris and simplify the cleaning of debris, thereby improving the detection efficiency, ensuring the accuracy and reliability of the detection results, and better meeting the needs of concrete detection.
