Description

Technical Field

[0001] The utility model relates to the technical field of highway bridges, in particular to a concrete testing instrument. Background Art

[0002] Highway bridge engineering includes the main bridge project and the ancillary engineering facilities in the overall bridge location. There are many ancillary engineering facilities, such as revetments and diversion dikes to maintain the stability of the river channel at the bridge location, approach bridges connecting the bridge head to the highway, railings on the bridge deck to prevent wheel collisions, sidewalk railings to ensure pedestrian safety, as well as bridge signs, navigation signs under the bridge and bridge deck lighting equipment. In the construction of highway bridges, the hardness, density, impermeability, freeze-thaw resistance, etc. of concrete are tested to ensure the safety, durability and reliability of the bridge structure. In many performance tests, the hardness of concrete occupies an important position.

[0003] After searching, the Chinese patent announcement number is CN212275407U, which discloses a hardness detection device for highway bridge construction. The patent has the advantage of being able to limit and fix the concrete test sample through the cooperation of the bottom plate, vertical plate, support plate, hydraulic telescopic rod, connecting plate, pressure sensor, pressure plate, test box, first fixed plate, second fixed plate, first bolt, semicircular clamp and concrete test sample, which solves the problem of the existing hardness detection device for highway bridge construction. During use, due to the single structure, the test sample cannot be limited and fixed, which leads to displacement during the test process, thereby affecting the test data and making it inconvenient for users to use.

[0004] However, after the pressure plate presses the concrete test sample, some debris may adhere to the bottom of the pressure plate. If it is not cleaned in time, the pressure on the sample will be uneven during the next use due to the uneven bottom of the pressure plate, affecting the accuracy of the next test.
