Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete strength detection device. Background Technique
[0002] The compressive strength of concrete is an important index to measure the quality of concrete. At present, the basic method for testing the compressive strength of concrete is to apply a certain external force to the concrete specimen and continuously load it until it is broken. By recording the load value during the compression process of the concrete specimen, the obtained ultimate load value is used as an index to evaluate the compressive strength of the concrete.
[0003] Before the current detection device conducts detection, it will cure the concrete to obtain a concrete specimen, and then move the concrete specimen to the detection device for detection. Currently, the basic detection method is to manually place the concrete specimen on the workbench for detection. Manual placement will result in the problem of inaccurate centering of the concrete specimen, so that the concrete specimen will be unevenly stressed during detection, ultimately affecting the analysis of the compressive strength of the concrete specimen. Moreover, during the concrete pressure detection, the fragmentation of the concrete will generate very large vibrations, which are likely to damage the machine components after long-term use; in the existing concrete compressive strength detection device, during detection, the concrete debris scatters everywhere, polluting the surrounding environment, and it is very inconvenient to clean up after the experiment. When the existing device detects cylindrical or cubic concrete products, it cannot fix concrete products of different specifications well, resulting in difficult detection and large errors.
