Technical Field

[0001] This utility model relates to the field of concrete bond strength testing technology, specifically an integrated concrete bond strength tester. Background Technology

[0002] A concrete bond strength tester is a specialized device used to test the bond strength between concrete and other materials. The instrument fixes the concrete substrate, adheres the anchor to the concrete surface or the surface of the material bonded to the concrete, and then applies a gradually increasing tensile force until the bond surface fails. The maximum tensile force applied is measured, and the bond strength is then calculated.

[0003] Most existing concrete bond strength testers adopt a split design, consisting of multiple independent components, resulting in a large overall size and heavy weight. When operating the equipment on the construction site, testers not only need to spend a lot of effort moving the equipment, but also encounter many inconveniences during installation and debugging due to its bulkiness, affecting testing efficiency and accuracy. This makes it difficult to meet the needs of modern construction projects for efficient and convenient testing. Therefore, there is an urgent need for a new type of integrated concrete bond strength tester to solve these problems. Utility Model Content
