Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete testing devices, in particular to a concrete strength testing platform. Background Art
[0002] A concrete strength testing device is a device mainly used for performing compression tests on concrete test blocks. The existing testing device is mainly composed of a pressure head and a hydraulic cylinder. The pressure head is driven by the hydraulic cylinder to act on the surface of the concrete test block to apply pressure to the concrete to test whether the concrete test block will break under a specific pressure. Although the traditional testing device can achieve the purpose of strength testing, it cannot clamp circular concrete blocks of different specifications and concrete blocks of different sizes, which reduces the clamping range and requires frequent equipment replacement, increasing the cost of use. In addition, the concrete blocks are not self-locked during clamping, which will cause the concrete blocks to loosen during the test and cause the extrusion plate to be misaligned, thereby reducing the service life of the device and its safety performance is poor. During the test, when the extrusion plate applies pressure to the concrete test block, if the concrete test block is crushed, it is easy to cause debris to splash. The splashing debris not only poses a safety hazard to people around, but also may damage surrounding instruments, and cannot protect the safety of equipment and personnel.
