Description

Technical Field

[0001] The utility model relates to the technical field of strength detection, in particular to a cement product strength detection device. Background Art

[0002] A cement product strength testing device is a device used to measure and evaluate the strength of cement products (such as concrete blocks, masonry, etc.). The strength test usually involves testing parameters such as the compressive strength, tensile strength, and flexural strength of cement products. For example, when testing the flexural strength of a cement rod, it is necessary to first fix the cement rod on a support point, apply a bending load, and measure the load at which it breaks during the bending process. A Chinese patent (publication number CN 217425054 U) discloses a cement rod strength testing device, which drives a transmission screw to rotate through a motor, so that a connecting plate threadedly connected to the transmission screw drives a clamping plate to move, thereby clamping the cement rod on the lifting frame to prevent the cement rod from shaking during testing, which affects the test effect. However, since it only fixes the cement rod in the middle, it cannot detect its flexural strength after applying a bending load. Therefore, the utility model proposes a cement product strength testing device to improve the above-mentioned problem. Utility Model Content
