Description

Background

Because various detection projects for detecting on-site entities of existing buildings are more and have a certain workload, detection personnel are required to be constantly familiar with and master all detection tools in actual work, experience is constantly summarized, coordination, high efficiency and simplification among detection tool users ("people") -detection tools ("tools") -detection objects ("objects") are constantly sought, and detection work efficiency is improved.

The traditional method adopts drilling measurement, so that the error is large, and the method belongs to breakage measurement, and is time-consuming and labor-consuming. The floor slab thickness gauge breaks through the traditional testing method and obtains the testing precision which is beyond imagination.

The working principle of the current floor slab thickness gauge is as follows: based on electromagnetic wave kinematics, dynamics principle and electronic technology. The floor slab thickness gauge mainly comprises units of signal transmission, receiving, signal processing, signal display and the like, when the probe receives electromagnetic signals of the transmitting probe, the signal processing unit analyzes according to the kinematic characteristics of the electromagnetic waves, automatically calculates the distance from the transmitting probe to the receiving probe, namely the thickness of the test board, and completes the display, storage and transmission of thickness values. The testing method comprises the following steps: the transmitting probe and the receiving probe are respectively arranged on the upper side and the lower side of the floor slab to be tested, the value displayed on the instrument is the distance between the two probes, and the receiving probe is only required to be moved, and the thickness of the floor slab is the thickness when the instrument is displayed as the minimum value. The method is specially used for measuring the thickness of nonmetal such as cast-in-situ floor slabs, concrete or other non-ferromagnetic media such as walls, columns, beams, wood ceramics and the like. The main characteristics are that: double-sided nondestructive testing, the floor slab does not need any treatment; no coupling agent is needed; the test speed is high, and 3-5 point tests can be measured in every three minutes on average; the test precision is high, and the error is less than 2mm; the instrument digitally prompts and guides the alignment probe.

And the second staff uses the receiving probe and the display instrument to detect the thickness of the detected object (the floor slab).
