Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy detection, in particular to a water-utilizing concrete rebound value detection device. Background Art

[0002] The concrete rebound tester is a testing device suitable for testing the strength of general building components, bridges and various concrete components (plates, beams, columns, bridge frames). The main technical indicators include impact function; spring stiffness; hammer stroke; maximum static friction of the pointer system and average value of rigidity. Concrete rebound value testing is a non-destructive testing method used to evaluate the strength of concrete structures. It uses a rebound hammer to knock on the concrete surface, and then infers the strength of the concrete based on the height of the rebound hammer. When the rebound hammer contacts the concrete surface, the contact force tilts, resulting in inaccurate measurement and affecting the measurement effect. Utility Model Content
