[0002] In order to ensure the safety of the building, it is necessary to measure the thickness of the floor slab in the building during the construction process to avoid the increase or decrease of the floor slab thickness, which will cause the increase of the center deflection of the floor slab and the decrease of the bearing capacity. Therefore, a corresponding floor slab thickness gauge is needed to perform this thickness measurement. However, the existing floor slab thickness gauge requires the staff to repeatedly calibrate it through the walkie-talkie during use, resulting in low work efficiency. Therefore, it is necessary to quickly locate the detection point for the staff's subsequent measurement work.
