Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, and specifically relates to a concrete quality and safety monitoring device for building construction. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation activities of the pipelines and equipment supporting them. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. In order to ensure the quality and safety of the house after the concrete solidifies, it is necessary to detect the strength of the concrete block after a certain proportion of ingredients are mixed and solidified, and the quality and safety of the concrete building can be obtained through the strength detection of the concrete block.

[0003] In the publicly disclosed Chinese patent application, the authorization announcement number: CN216126148U, the patent name: A high-sensitivity concrete compressive strength monitor for concrete detection. Although this prior art can simply and quickly clean the broken blocks after the detection through the cooperation of the bottom plate, support columns, top plate, hydraulic oil tank, hydraulic telescopic rod, pressure plate, protective cover, cleaning brush, slider, chute, threaded block, threaded rod, motor, support plate and controller, saving time and effort and greatly improving the cleaning efficiency, bringing great convenience to the detection work. However, when this prior art detects the strength of the concrete block, it uses a hydraulic telescopic rod to drive the pressure plate to press down on the concrete block, and this prior art cannot effectively make the hydraulic telescopic rod drive the pressure plate to press down on the center of the concrete block. When the edge of the concrete block is stressed, the concrete block will break within a short time, resulting in a lower strength of the concrete block obtained from the test result. The test result shown cannot be used as the normal strength of the concrete block, that is, the test strength of the concrete block is inaccurate. Therefore, it is necessary to press down on the middle part of the concrete block to make the middle part stressed, and the concrete block breaks after being stressed in the middle part, and the strength of the concrete block obtained therefrom is relatively accurate.

[0004] To sum up, in order to solve the problem in the prior art that the pressure mechanism cannot accurately press down on the center of the concrete block, resulting in inaccurate test strength of the concrete block, this case is specifically proposed to solve the problem.
