Abstract

The invention relates to a concrete core sample flexural test device, which is characterized in that it comprises a frame (1), a tensile tester (6) is arranged on the frame, and a pull ring (5) is arranged in the frame, The pull ring is connected to the tensile tester through the pull rod (7). The advantages of the invention: the device not only has light design, convenient maintenance, and low cost, but also has the characteristics of high efficiency, speed, accuracy, and little damage to the structure when testing the densely reinforced parts in concrete members.

Description

technical field [0001] The invention relates to a device for testing the compressive strength of concrete, in particular to a concrete core sample flexural test device. Background technique [0002] At present, the testing methods for the compressive strength of concrete are mainly rebound method and core drilling method. The rebound method has high requirements on the surface quality of concrete components, and it is an indirect parameter reflecting the compressive strength of concrete. It is also easy to bring errors in the test, and the accuracy of the test results is not good; After the core sample needs to go through many processes such as cutting, repairing, maintenance and compression test, the operation is cumbersome and there are many influencing factors. Therefore, it is of great significance to explore a new testing technology to promote the development of concrete compressive strength testing technology. After extensive searching, a comparatively ideal technica...
