Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete detection device for construction engineering supervision. Background Art

[0002] The quality and strength of concrete is one of the important indicators to ensure the quality of the project. In order to ensure that the concrete meets the design requirements, strength testing and supervision are required. Common methods for concrete strength testing include non-destructive testing and destructive testing. The commonly used methods for destructive testing are steel bar pull-out testing and concrete pressure testing.

[0003] Existing concrete detection devices can limit the concrete so that the detected concrete is not easily offset. For example, Chinese patent application number CN202320755039.9 discloses a stable concrete detection device for construction project supervision, including an installation frame and a support frame. Two relatively arranged placement devices for placing concrete slabs are installed on the installation frame. A supporting device is fixedly installed on the top of the installation frame. A pressing device for pressing the concrete slab is fixedly installed on the support device. The top of the support frame is fixedly connected to the bottom of the installation frame.

[0004] The two fixing frames and two mounting frames of this device clamp the concrete block by being close to each other. Since the two fixing frames and two mounting frames are respectively located on the four sides of the mounting frame, the concrete block is easily obstructed by the fixing frames and the mounting frames when placed on the mounting frame, and the debris generated when the concrete block is crushed is easy to fall on the fixing frames and the mounting frames. Since the surfaces of the fixing frames and the mounting frames are uneven, subsequent cleaning is affected. Utility Model Content
