Abstract
Description
Technical Field
[0001] The utility model relates specifically to the technical field of construction engineering, in particular to an intelligent management facility for concrete cubic compression test blocks. Background Art
[0002] Intelligent management facilities for concrete compressive test cubes are the primary means of concrete quality inspection for construction projects and a crucial step in delivery inspections for ready-mixed concrete companies and construction companies. They are also a crucial tool for project quality supervision departments to monitor project quality, making the management of intelligent management facilities for concrete compressive test cubes at construction sites particularly important. In previous construction projects, many construction companies, in order to ensure smooth project acceptance, often replaced on-site test blocks with test blocks produced in-house, evading oversight by project quality supervision departments and creating numerous quality risks. To address this issue, quality supervision departments in many regions have introduced test block QR code systems or NFC chip implants to ensure the unique authenticity of test blocks.
[0003] However, the test block QR code system or NFC chip implantation can only ensure that the concrete test blocks produced at the construction site have not been replaced, and cannot guarantee the authenticity and accuracy of the concrete test block strength. In fact, there are many factors that affect the compressive strength of concrete test blocks. After the test blocks are formed, the curing conditions are extremely important. The temperature and humidity must meet the relevant requirements of national standards and must last for 28 days. If the temperature and humidity do not meet the requirements, the accuracy of the test block strength test cannot be guaranteed. In addition, after the test blocks are demolded, the early strength is low, and mechanical shocks such as collisions and knocks will cause the concrete strength to drop significantly.
[0004] Over the past two years, with the continued downturn in the construction market, construction companies, concrete companies, design firms, and other construction-related businesses have faced a crisis of survival. To cope with the current difficulties, many companies have made significant layoffs, resulting in a significant loss of technical personnel and a serious decline in construction management. Management of concrete compression test blocks on construction sites is extremely chaotic, with inadequate temperature and humidity conditions for curing being commonplace. Worse still, test blocks are haphazardly scattered after demolding, and some are even weighed down by heavy objects such as rebar, making accurate strength measurements impossible.

[0043] The working principle of this utility model is: Figure 1-Figure 2 As shown, when the compression test block body 1 is formed, the end of the lead zirconate titanate piezoelectric ceramic 2 is buried in the concrete to monitor the stress of the compression test block body 1, and the ends of the copper thermal resistor 5 and the manganese tungstate humidity-sensitive ceramic 4 are exposed to the air to monitor the temperature and humidity changes in the environment. This can achieve full-process supervision of the stress, temperature and humidity of the concrete compression test block and its own uniqueness, which is conducive to the comprehensive supervision of the quality of ready-mixed concrete. The structure uses a connecting rod 3 to connect the manganese tungstate humidity-sensitive ceramic 4 with the lead zirconate titanate piezoelectric ceramic 2 embedded in the compression test block body 1 in an integrated manner; when making the test block monitoring device, the manganese tungstate humidity-sensitive ceramic 4 film is wrapped on the surface of the copper thermal resistor 5 as the upper end of the monitoring device, and the lead zirconate titanate piezoelectric ceramic 2 as the lower end of the monitoring device.
