Description

Technical Field

[0001] The utility model relates to the technical field of thickness detection devices, and more specifically, to a device for detecting the thickness of a steel bar protective layer. Background Art

[0002] In the field of construction engineering, reinforced concrete structure is one of the most common structural forms. Steel bars play a vital bearing role in concrete structures, and the thickness of the steel bar protective layer is directly related to the durability, safety and service life of the structure. With the continuous development of the construction industry, the quality requirements for reinforced concrete structures are getting higher and higher. Accurately detecting the thickness of the steel bar protective layer has become a key link in ensuring the quality of the project. The traditional steel bar protective layer thickness detection method mainly includes the damage detection method. The damage detection method requires local destruction of the structure. Usually, a special core drilling equipment is used to drill core samples on the concrete structure, and then the distance from the steel bar to the concrete surface is directly measured to determine the thickness of the steel bar protective layer. Most of the drilling process is carried out by the inspector using a handheld electric drill to drill the reinforced concrete. Although this method can achieve the drilling of core samples, a large amount of dust and noise will be generated during the process, which not only has an adverse impact on the detection environment, but also the flying dust and high noise may endanger the health of the inspector. In order to solve the shortcomings of the existing technology, we propose a steel bar protective layer thickness detection device. Utility Model Content
