Frame Detector for Steel Frame Drywall Using Electromagnets

摘要

This design aims to provide a frame detector that can easily and accurately detect the location and extent of frame in drywall using steel frame such as light steel. The skeleton detector according to the present invention includes a power source 1, a skeleton detection unit 5, and a detection display lamp 6, and the skeleton detection unit 5 includes an electromagnet and a plurality of magnetic field sensors arranged linearly. The magnetic field sensor detects a change in the direction of magnetic flux emitted from the electromagnet, and the detection display lamp 6 amplifies the detection signal of the magnetic field sensor and emits light. In addition, the frame detector includes a magnetic force control lever (4) for controlling the magnetization strength of the electromagnet by controlling the current supplied from the power source.
