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 Reinforced Bar Insertion Non-Destructive Investigation Research Association (TESHICK). NETIS Registration Number: CG-190002-A For more details, please contact the sales staff at K.F. Co., Ltd., which serves as the secretariat. 【Features of NND】 ■ Equipped with a noise filter that reduces the scattering of ultrasound caused by the unique screw-shaped structure of the reinforced bar insertion material. ■ The combination of newly developed sensors and two types of noise filters allows for a wide range of compatibility with various embedded reinforcement materials. ■ Features an easy-to-understand display specifically designed for reinforced bar insertion work. ■ Measurements can be safely conducted in unstable areas through remote operation. ■ Capable of measuring reinforced bar insertion 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 arduous task of measuring each one individually, which involves risks. Additionally, during inspections in unstable areas 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. There have been instances in past audits where deficiencies in the completed shape of rebar insertion work were pointed out. By making it "visible" through this system, we can enhance the reliability of construction and add value to management.
