Description

TECHNICAL FIELD

[0001] The utility model relates to a positioning fixing device for concrete detection belongs to concrete detection technical field. BACKGROUND

[0002] A large amount of concrete is used in the field of construction, and the quality of concrete is directly related to the service life of the building. The compressive strength of concrete is one of the main indicators directly reflecting the degree of concrete quality, so it is necessary to detect and process the concrete.

[0003] The existing concrete is often placed directly on the test bench of the concrete pressure testing machine during detection. Since there is no separate positioning structure for the concrete test block, the test block is prone to be placed off-center, resulting in uneven stress on the detected concrete test block, and thus the detection data is inaccurate.

[0004] To solve the above problems, the industry has emerged corresponding patents, such as the Chinese utility model patent with the patent name of "a positioning device for concrete detection" and the authorization announcement number of CN 218726013U. In the above patent, multiple positioning blocks are set to fix the test block, improving the accuracy of the test block position when placed and the stability of the test block during the test process.

[0005] However, the above patent has the following problems:

However, since the spacing between the limiting holes is fixed, the spacing between the positioning blocks is constant, which may result in that the existing positioning blocks can only fix test blocks of some fixed sizes, while the sizes of test blocks are not the same, which leads to that the range of use of the positioning blocks in the existing patent is narrow, and the adaptability of the device is poor.

[0007] 2. In the above patent, a center mark is provided to position the test block. If the size of the test block is large, the center mark may be covered, making it difficult to align the center of the test block with the center of the neutral mark. If the size of the test block is smaller than the size of the center mark, it is also difficult to align the center of the test block with the center of the neutral mark in the neutral mark, and the problem of inaccurate positioning of the test block may also occur.
