Technical Field

[0001] This utility model relates to the field of crack width measurement technology, specifically to a device for detecting the crack width of concrete beam components. Background Technology

[0002] Wall cracks are cracks that occur on the surface of a building structure. They have an adverse effect on the appearance and safety of the wall. Therefore, it is necessary to inspect the wall cracks and calculate the crack width after the building construction is completed in order to ensure the safety of subsequent construction and subsequent repair work.

[0003] Patent specification CN219757132U discloses a device for detecting the crack width of concrete beam components, including a main scale mechanism. The adjustment mechanism includes a connecting plate, with an adjusting screw fixedly connected inside the connecting plate. The right end of the adjusting screw passes through the middle of a slider and extends therefrom. A threaded sleeve is threadedly connected to the middle of the adjusting screw. The outer circumference of the threaded sleeve is rotatably connected to the right opening of a limiting seat. The left end of the threaded sleeve is fixedly connected to the right side of a first bevel gear. The first bevel gear meshes with a second bevel gear, and an adjusting rod is fixedly connected to the middle of the second bevel gear. The front end of the adjusting rod passes through the middle of a rotating seat and extends therefrom. This device for detecting the crack width of concrete beam components, through the adjustment mechanism driving the main scale mechanism for fine-tuning, achieves higher adjustment precision and more accurate measurement values ​​when adjusting the main scale and secondary scale mechanisms.

[0004] While the aforementioned technical solutions can measure wall cracks, in practice, the measuring device needs to be held by hand. When the cracks are high, it is impossible for staff to hold the device for measurement, which presents certain limitations. Therefore, we propose a device for detecting the width of cracks in concrete beam components. Utility Model Content
