[0002] The thickness of the steel bar protective layer is the distance from the outer edge of the main load-bearing reinforcement of the reinforced concrete slab to the concrete surface. Testing the thickness of the steel bar protective layer is equivalent to testing the concrete thickness of the reinforced concrete slab.

[0003] The prior art patent document CN221505935U provides a steel bar protective layer thickness detection device, which can collect the debris dropped from the reinforced concrete slab during detection, effectively preventing the problem of excessive debris on the slab from spilling elsewhere and making it inconvenient to clean up later, thereby ensuring the cleanliness of the detection device during the detection process.

When detecting other parts of the reinforced concrete slab, the operation is relatively cumbersome and the efficiency is low, which cannot meet people's needs. Therefore, we need a steel bar protective layer thickness detection device. Utility Model Content
