Description

Technical Field

[0001] The utility model relates to the technical field of building safety detection, in particular to a crack change quantitative monitoring device. Background Art

[0002] At present, cracks will appear in buildings as the use time increases. Since cracks will affect the safety of buildings, they need to be detected after they appear. When the size of the cracks is within a safe range, there is no need to repair and reinforce the building. However, when the cracks are large enough, the building needs to be reinforced and repaired. Therefore, cracks must be detected after they appear in the building.

[0003] The existing patented real-time monitoring device for building cracks has a publication number of CN209655952U. In this embodiment, the changes in the cracks are observed in real time by observing the changes in the cracks. The scale value aligned with the two sides of the crack can be read at any time, and the change in the crack can be judged by the difference between the two scale values.

[0004] The inventor of the above device found in actual operation that the scale line needs to be observed manually each time. When the crack is too large, manual observation poses a safety hazard, that is, it is inconvenient to observe the crack condition in real time. Therefore, we proposed a quantitative monitoring device for crack changes. Utility Model Content
