A system that uses ultrasonic technology to verify the quality of rebar insertion work after construction is completed.
The non-destructive measurement system using ultrasound, NND, is a system promoted by the Rebar Insertion Non-Destructive Investigation Research Group (TESHICK). NETIS Registration Number: CG-190002-A For more details, please contact the sales staff at K.F. Co., Ltd., where I serve as the secretariat. 【Features of NND】 ■ Equipped with a noise filter that reduces the scattering of ultrasound caused by the unique screw-shaped characteristics of rebar insertion reinforcement materials. ■ The combination of newly developed sensors and two types of noise filters allows for wide compatibility with various embedded reinforcement materials. ■ Features a user-friendly display specifically designed for rebar insertion work. ■ Measurements can be safely conducted in unstable areas through remote operation. ■ Capable of measuring rebar insertion reinforcement materials with a diameter of 19 mm or more and a length of approximately 5.0 m. ■ Gyro sensor Now capable of measuring the installation angle of reinforcement materials. Can be easily fixed with a powerful magnet.

basic information
Since the reinforcement materials for rebar insertion work are placed underground, it is not possible to confirm the completed shape after construction. Because they become invisible, the manager undertakes the difficult task of measuring each one individually, which involves risks. Additionally, during inspections in unstable locations such as high places, not only the manager but also the client (observer) may be exposed to danger. The non-destructive measurement system "NND" can measure the length of the reinforcement materials and the drilling length after the construction is completed. Since data transmission uses Wi-Fi, measurements can be taken from a safe location through remote operation, significantly reducing the burden on the measurer. Rebar insertion work has previously been pointed out for insufficient shape in past accounting audits. By making it "visible" through this system, it enhances the reliability of construction and adds value to management.
