Description

Technical Field

[0001] This utility model relates to the field of building defect detection technology, and in particular to a device for rapidly recording the morphology of surface cracks in building components. Background Technology

[0002] Walls are prone to cracking due to prolonged exposure to wind and sun. Wall cracks are cracks that occur in the wall structure of a building. Depending on the material, they can be categorized as concrete wall cracks, brick wall cracks, cracks in new partition walls, and cracks caused by different materials. Once cracks appear, a testing instrument is typically used to detect their width or depth.

[0003] Currently, the main devices for recording building cracks on the market are physical crack cards and sensors that monitor the development of crack width, but cannot record the crack shape. When it is necessary to analyze the cause and distribution pattern of cracks based on the crack shape on the component, the only way is for the inspectors to sketch the crack on-site and then organize it into a CAD file on the computer. This cannot guarantee the accuracy and timeliness of the crack shape.

[0004] The problems in building defect detection work are that on-site recording takes a lot of time, and the recording methods and completeness of the records vary from person to person. Omissions, errors, and discrepancies between the locations of defects in two separate records are common. This is especially true for building structures without design drawings. The recording of building defects and the drawing of crack diagrams on individual components waste a lot of time. Inspectors need to spend time organizing and recalling the original on-site inspection records later, which makes it impossible to form work results in a timely manner and ensure the completeness and accuracy of the records.

[0005] Therefore, a device for rapidly recording the surface crack morphology of components is provided to address the shortcomings of existing technologies. Utility Model Content

[0022] This invention provides a device for rapidly recording the morphology of surface cracks on building components. The device uses a detector and a recording pen to record the crack's shape, particularly for complex cracks with irregular shapes and distributions on building walls and panels. It replaces the previous method of manually drawing crack diagrams on paper. The recording pen is moved directly from the beginning to the end of the crack, and a position sensor records the pen's movement trajectory. This trajectory is then transmitted to the detector to generate the complete crack shape. A camera on the pen automatically locates and determines the maximum width of the crack during movement.

[0037] In one embodiment, the recording pen is connected to the detector; the recording pen includes a pen body 5, a position sensor and a camera, both of which are connected to the pen body 5. The position sensor is used to record the movement trajectory of the pen body 5 and transmit the movement trajectory to the detector to generate the crack shape, and the camera is used to record the position where the crack is largest during the movement of the pen body 5.

[0038] This invention utilizes a detector and a recording pen to record the morphology of cracks, particularly for complex cracks with irregular shapes and distributions on building walls and slabs. It replaces the previous method of manually drawing crack diagrams on paper. The recording pen moves directly from the beginning to the end of the crack, and a position sensor records the pen's movement trajectory. This trajectory is then transmitted to the detector to generate the complete crack morphology. A camera on the pen automatically locates and determines the maximum width of the crack during movement. Compared to traditional manual crack drawing, this method records crack information (length, width, shape, and distribution location) more accurately and intuitively. This device for rapidly recording the morphology of surface cracks in building components features rapid recording of the complete crack morphology. It can more accurately reflect the morphological information and development patterns of cracks on the surface of building components, and can more intuitively and accurately display the location and distribution of other defects in buildings. This allows inspectors to analyze the causes of building defects and the impact of existing defects on building safety and usability, improving the efficiency of inspectors, ensuring the timeliness and accuracy of defect recording, and guaranteeing significant engineering application value in building safety assessments and urban renewal projects.
