Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a comprehensive hardness measuring instrument for building inspection. Background Art

[0002] In construction projects, in order to ensure the strength and hardness of buildings, it is necessary to conduct comprehensive hardness testing on building materials to avoid the situation where the strength of some building materials does not meet the requirements, resulting in the building not meeting the acceptance standards or causing safety hazards in subsequent use due to the low hardness of building materials. The hardness tester used in the construction field is usually an indentation hardness tester. The indentation hardness tester determines the hardness of the measured sample by measuring the depth or displacement of the indenter into the measured sample and is widely used.

[0003] In the process of using existing measuring instruments, the object to be tested is usually placed on the testing table, and then the testing head is pushed to fit the object to be tested by hydraulic equipment. The pushing force of the hydraulic equipment drives the testing head to apply pressure to the object to be tested. The pressure sensor inside the testing head can accurately calculate the pressure value of the object to be tested, thereby judging the hardness of the object to be tested. However, during the extrusion process, such as concrete blocks, the cement stone residue on the surface falls off due to the extrusion force. If it is not cleaned in time, the waste residue will affect the subsequent placement of the object to be tested, resulting in inaccurate test data. In order to solve this problem, a comprehensive hardness measuring instrument for building inspection is proposed. Utility Model Content
