Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete component technology, specifically a device for detecting cracks in concrete components. Background Technology
[0002] The impact of cracks on concrete structures should not be underestimated. Once the depth and width of cracks exceed the critical values that the concrete structure can withstand, it not only affects the appearance of the structure, but more importantly, it may impair the integrity and load-bearing capacity of the concrete structure, thus affecting its normal use. In extreme cases, severe cracks may even cause safety accidents, posing a huge risk to personal and property safety.
[0003] When detecting crack depth in concrete components, crack detectors are usually used as an auxiliary tool. Manually marking the crack with a ruler is required. After marking, the probe is manually coated with coupling agent and placed at the marked line. Repeated testing is then performed to determine the crack depth. However, the lack of support during testing makes the process time-consuming, labor-intensive, and inefficient. Utility Model Content
