Description

Technical Field

[0001] The utility model relates to the technical field of floor slab thickness gauges, in particular to a floor slab thickness gauge for construction engineering inspection. Background Art

[0002] A floor thickness gauge is a device used to measure the thickness of concrete floor slabs. It is usually used to check the thickness of concrete floor slabs at construction sites or when maintaining existing buildings. The floor thickness gauge measures the thickness of the floor slab by emitting ultrasonic pulses and receiving reflected signals. The propagation speed of ultrasonic waves in concrete is known. By measuring the time difference from sending to receiving, the distance the signal travels can be calculated, thereby determining the thickness of the floor slab.

[0003] The floor thickness gauge is mainly used to measure the thickness of concrete floor slabs. The transmitting probe is connected to the connecting telescopic rod, and the transmitting probe is pushed to the bottom of the measured floor slab to restrain it. Then the main unit is placed on the top of the measured floor slab, and the measurement interface is entered to start the measurement. When the transmitting probe is pushed to the bottom of the measured floor slab, the staff needs to continue holding the connecting telescopic rod. As the measurement time increases, the staff needs to expend a certain amount of effort, making it difficult for the staff to easily push the transmitting probe to the bottom of the measured floor slab and restrain it together. Therefore, we propose a floor thickness gauge for construction engineering inspection. Utility Model Content
