Description

Technical Field

[0001] The utility model relates to the technical field of crack width detection, in particular to a device for detecting the width of cracks in reinforced concrete walls. 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] At present, the existing technology of a device for detecting the width of a crack in a reinforced concrete wall mostly uses a caliper for detection, and the caliper detection method has many shortcomings. When the gap width is too small, the measuring claw on the caliper cannot be extended into the gap, and when the measuring claw on the caliper is extended into the gap, the measuring claw may cause the powder of the wall to fall during the detection, thereby expanding the gap. On the other hand, the traditional caliper detection cannot detect when there is a gap at a high place in the wall because the length of the caliper is fixed, and when detecting a slightly higher place, the user needs to remove the caliper to obtain the gap width, which has great limitations and is not very practical.
