Description

Technical Field

[0001] This utility model relates to the field of testing and sampling technology, specifically a sampling device for testing the strength of building concrete. Background Technology

[0002] Concrete strength testing is a core component in ensuring the safety of concrete structures, meeting design requirements, and evaluating structural performance. Its core purpose is to determine the actual compressive strength of concrete (the core indicator of concrete strength) using scientific methods, providing data support for structural construction acceptance, use, maintenance, renovation, and reinforcement.

[0003] Concrete strength testing can be divided into three main categories: non-destructive testing, semi-destructive testing, and destructive testing. Among them, the core drilling method of semi-destructive testing is applicable to concrete of all strength grades. A cylindrical core sample (usually 100mm or 150mm in diameter, with a height ≥ diameter) is drilled from the concrete structure using a "core sample drill". After processing, the core sample is subjected to a compressive strength test on a press to directly measure the compressive strength of the core sample. Then, the strength is corrected to the actual strength of the structural concrete based on the core sample size (such as the height-to-diameter ratio).

[0004] However, in actual use, the above-mentioned sampling device for testing the strength of building concrete has several drawbacks. First, during the drilling and sampling process, the testing personnel do not have a proper grasp of the sampling structure at the bottom of the device, which can easily lead to drilling deviation or device tilting and injury to personnel. Second, the overall structure of the device has relatively weak downward pressure, which can easily affect the sampling results. Therefore, we propose a new sampling device for testing the strength of building concrete. Summary of the Invention
