Description

Technical Field

[0001] The utility model relates to the technical field of building detection equipment, in particular to a building hollowing detection device. Background Art

[0002] Common buildings are constructed of concrete, in which steel mesh is poured to improve the strength of the structure. However, due to quality problems in construction, hollowing may occur on the ground, wall or ceiling due to loose pasting and bonding. The hollowing may affect the decorative performance in the later stage, and may also cause wall peeling and water seepage. Therefore, after the construction of the building is completed, the inner wall of the building is generally tested for hollowing. The traditional method is to use a hollowing hammer to hit the wall, and identify whether it is hollow based on the sound. The hollowing can then be recorded for later repair. However, when a hollowing hammer is used manually, the strength of each knock cannot be guaranteed to be consistent, and misjudgment may occur easily. In addition, after using a hollowing hammer for hollowing detection, the staff also needs to mark the hollow area. Currently, most staff use a marker pen to mark, and the marked position is not necessarily the area hit by the hollowing hammer, resulting in errors in the selection of the wall in the hollow area during later repair.

[0023] The utility model discloses a building hollow drum detection device, which is used for hollow drum detection on the wall surface of a building. The telescopic rod 2 is driven to move by a moving wheel 1. At the same time, the height of a knocking head 10 is adjusted by the telescopic rod 2, so that the knocking head 10 is located on one side of the wall surface to be detected. Then, the electromagnet 8 is turned on.
