Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a concrete test block compression testing and feeding clamping device. Background Art

[0002] Compressive strength testing of concrete test blocks can assess the strength of concrete and determine its bearing capacity and safety performance. This is of great significance to the design, construction, and acceptance of engineering projects such as building structures. When performing compressive strength testing on concrete test blocks, it is necessary to remove the cured concrete test blocks and then manually place them on the lower platen of the pressure testing machine to load the concrete test blocks. Since concrete test blocks are generally 150mm or 200mm long concrete blocks and have a certain weight, when carrying them, people usually place their palms close to the ends of the concrete test block and support the bottom of the concrete test block with their fingers. When lowering the concrete test block, the fingers are easily squeezed between the concrete test block and the lower platen, which can easily cause injury to the fingers.
