Device and method for detecting sticking compactness of steel plate

Abstract

The invention provides a device and method for detecting sticking compactness of a steel plate. The device comprises a plurality of transmitting transducers used for transmitting ultrasonic waves, a plurality of receiving transducers used for receiving ultrasonic waves, a scanning device and a data processing system, wherein the transmitting transducers, the receiving transducers and the data processing system are sequentially connected, the scanning device is connected with the data processing system in parallel, and the data processing system comprises an amplifier used for amplifying signals received by the receiving transducers and an oscilloscope used for graphic display of data. By the adoption of the device and method, components are not damaged, detection is reliable, work load is small, working efficiency is high, and vacancy degree can be detected qualitatively and quantitatively.

Description

technical field [0001] The invention relates to the field of civil and construction engineering, in particular to a device and method for detecting the density of pasting of steel plates. Background technique [0002] Bonded steel reinforcement, also known as pasted steel plate reinforcement, is to bond the steel plate to the surface of the concrete member with a high-performance epoxy adhesive, so that the steel plate and the concrete form a unified whole, and use the good tensile strength of the steel plate to enhance the bearing capacity of the member For the purpose of capacity and stiffness, bridges and houses can be reinforced. Therefore, the paste quality of the steel plate directly affects the reinforcement effect, so the detection of the paste quality is very important. [0003] The following are common detection methods: [0004] Drilling and coring method, specifically, randomly select a certain detection point to open a hole in the concrete, and extract a concr...

Problems solved by technology

[0021] First of all, it needs to be tapped with a small hammer for manual preliminary judgment, and the subjective influence factors are large.

[0022] Secondly, the surface-to-surface measurement is adopted. In order to detect the entire section, many detection points need to be arranged on the component to be tested, which increases the detection workload and reduces work efficiency.

[0023] Finally, there is too much detection data information, no data processing system has been established, and the entire detection process and data processing work is complicated
