Description

Technical Field

[0001] The utility model relates to the field of detection-related technologies, in particular to a concrete wall crack measuring device. Background Art

[0002] When detecting cracks in reinforced concrete walls, since the gaps are generally small, larger external equipment cannot be inserted. Generally, a vernier caliper is used for detection. The detection method is to insert the measuring claws of the vernier caliper into the cracks in the concrete wall, and then detect the width of the gap.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent No.: CN218723674U discloses a device for detecting the width of cracks in reinforced concrete walls, including a caliper body, an inner measuring claw is arranged at the upper position of the left end of the caliper body, a vernier is arranged at the middle outer position of the caliper body, and an extension device is arranged at the right end of the caliper body. The extension device includes an annular magnet, a telescopic ruler moving plate, and a columnar magnet. An annular magnet is arranged at the right end of the caliper body, a telescopic ruler is arranged at the middle position inside the caliper body, and a moving plate is arranged at the right side of the telescopic ruler. In this new jig for detecting the spacing of wall gaps, when the user opens the vernier ruler and uses the measuring claw to measure, he faces a wall with a large spacing. The length of the caliper body itself cannot meet the current problem of measuring the length. The new type can achieve measurement between walls with a large spacing by setting the telescopic ruler in the extension device.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that after the measurement, due to the small scale lines on the vernier caliper, it is difficult for visually impaired people to read the values, which is not conducive to reading and causes a high probability of reading the wrong values.

[0006] To this end, we proposed a concrete wall crack measurement device to solve the above-mentioned drawbacks. Utility Model Content
