Description

Technical Field

[0001] The present application relates to the technical field of concrete testing equipment, and in particular to a concrete strength testing device for construction. Background Art

[0002] Concrete strength testing is an important means of evaluating the quality of concrete structures. The rebound hammer method is one of the common methods for testing concrete strength. The rebound hammer is used to hit the concrete surface, and the rebound value is determined by the hardness of the reflection surface. The higher the rebound value, the higher the concrete strength. During the test, it is necessary to ensure that the axis of the rebound hammer is perpendicular to the concrete test surface, and read and process the rebound value according to the prescribed procedures to infer the strength of the concrete.

[0003] For example, a concrete rebound tester with patent number (CN202021774491.2) is characterized in that: it includes a rebound tester body, a support frame and a plurality of support legs, wherein the plurality of support legs are fixedly arranged at the same end of the support frame and are used to form a set distance between the support frame and the concrete plane; a sliding plate is slidably connected in the support frame, and the sliding plane of the sliding plate is arranged parallel to the concrete plane; a sliding block is slidably connected on the sliding plate, and the sliding direction of the sliding block is parallel to the concrete plane and perpendicular to the sliding direction of the sliding plate; the rebound tester body is slidably connected to the sliding block through a mounting block, and the sliding directions of the rebound tester body and the sliding block are toward or away from the concrete plane, and the rebound tester body is arranged perpendicular to the concrete plane; positioning components for positioning the sliding plate and the sliding block are respectively arranged on the support frame and the sliding plate.

[0004] In the above structure, since the sliding plane of the sliding plate is parallel to the concrete plane, the sliding direction of the sliding block is parallel to the concrete plane and perpendicular to the sliding direction of the sliding plate; the rebound hammer body is arranged perpendicular to the concrete plane; so that the rebound hammer can always remain perpendicular to the concrete plane during testing; positioning components are arranged on the support frame and the sliding plate, so that the positioning of the sixteen detection points is more stable and will not shake; but when the device is in use, it is also necessary to manually move the position of the rebound hammer body so that the rebound hammer can complete the data detection of the sixteen detection points, which is inconvenient to operate.

[0005] Therefore, it is necessary to design an automatic positioning construction concrete strength testing device to make it easier for workers to operate. Utility Model Content
