Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a single-sided continuous detection device for floor thickness based on ultrasonic principle. Background Art

[0002] Traditionally, there is a floor measurement device, which is a measurement device based on the principle of electromagnetic method, consisting of a transmitter, a receiver, a host, an extension rod, etc. During measurement, the transmitter is connected to the extension rod and placed on the bottom surface of the floor, and the receiver is placed on the top surface of the floor. When the center positions of the transmitter and the receiver coincide on the plane, the host can automatically calculate the thickness of the floor by the propagation speed and time of the electromagnetic wave in the floor. However, this method requires two people to be located on the upper and lower floors of the floor, and the transmitter and the receiver must completely coincide to ensure the measurement accuracy. It is difficult to implement on site and the efficiency is low. When it is impossible to measure the structure to be measured separately, it will not be possible. For this reason, ultrasonic thickness gauges are widely used. Ultrasonic thickness gauges measure thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe, and the thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. During measurement, the probe needs to be perpendicular to the surface of the object to be measured. When measuring the floor, the upper end surface of the floor will seriously affect the direct measurement results due to the accumulation of building debris.

[0003] For this purpose, we propose an ultrasonic thickness measuring device which can continuously inspect the thickness of the floor slab on the bottom surface of the floor slab. Summary of the invention
