Description
Technical Field
The invention relates to the technical field of real estate evaluation, in particular to a hollowing detector for real estate evaluation.
Background
The hollowing is caused by the air existing in the original masonry and the dust layer, during detection, a clattering-clattering sound is generated by tapping the plastering layer and the leveling layer with an empty drum hammer or a hard object, so that the hollowing is the hollowing phenomenon in the house quality, which generally refers to the phenomenon that the hollowing occurs between the floor, the wall surface, the ceiling decoration layer and the structural layer of the house due to the fact that the floor, the wall surface, the ceiling decoration layer and the structural layer are not firmly adhered and combined, and the empty drum is commonly called as 'two layers of leather'.
Need use hollowing detection device after the tile is spread and is pasted, but current hollowing detects and mostly is the artifical detection of knocking, and long-time measuring lets the user produce fatigue easily to cause the phenomenon of inconvenient detection, the inconvenient user is spread the condition of pasting to the tile and is detected, has reduced detection device's practicality.
