Description

Technical Field

[0001] The utility model relates to the field of concrete detection, in particular to a concrete rebound detection device. Background Art

[0002] Concrete rebound tester is a kind of testing equipment used to measure the strength of general building structures, bridges and various concrete components. Its main technical indicators include impact function, spring stiffness, hammer stroke, maximum static friction of pointer system and average rigidity.

[0003] After searching the patent document with the announcement number CN220508700U, the patent document discloses "a concrete rebound detection device, which cooperates with the concrete rebound detection structure and the square plate, and the electric telescopic rod is started to drive the second vertical plate to slide to the right on the slideway processed on the inner wall of the first shell, and the cooperation of the first vertical plate drives the two straight rods to swing relative to each other, and the relative swing of the two straight rods drives the cross bar to slide downward on the slideways processed on both sides of the inner wall of the first shell, drives the vertical rod to move downward in the first shell, and drives the square plate to move downward at the same time. The square plate moves downward and drives the instrument body to move downward, so that the probe at the tip of the instrument body contacts the surface of the concrete wall, stably tests the strength of the concrete wall, and detects the rebound of the concrete. It is not necessary to manually drive the instrument body to move downward to perform the rebound detection work, thereby reducing manual labor."

When the vertical concrete wall needs to be inspected, the operator is required to place the device horizontally and push it against the vertical wall for use, or to push the device horizontally against the vertical wall through an additional support structure, which makes it inconvenient for the device to operate on the vertical concrete wall.
