Description

Technical Field

[0001] The utility model relates to the technical field of building detection tools, in particular to a hollowing detector for real estate evaluation. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and plaster layers. "Hollowing" in house quality generally refers to the hollowing phenomenon caused by the loose connection between the floor, wall, and ceiling decoration layers (plastering or pasted tiles) and the structural layers (concrete or brick walls) of the house. This phenomenon often occurs in real estate.

[0003] The current hollowing detector for real estate assessment and detection, the utility model with authorization announcement number CN202719982U discloses a hollowing detection hammer for civil engineering, including a handle, a hammer rod and a hammer head. The hammer rod is welded to the top end of the handle and the handle and the hammer rod are vertically welded into one, the hammer head is welded to the upper end of the hammer rod, the hammer head and the hammer rod are perpendicular to each other and form a T shape. When the hollowing detection hammer is used to detect the wall, the staff holds the handle and then uses the hammer head to knock on the inspected wall to judge whether there is hollowing in the inspected wall by the sound.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the hammer rod and the handle of the hollow drum detection hammer are welded to each other. When it is necessary to detect the roof or higher buildings, the hollow drum detection hammer will be unable to perform the detection due to insufficient length. Utility Model Content
