Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a building concrete performance detection sampling device. Background Art

[0002] During the construction process, concrete needs to experience the effects of various environments and forces, such as moisture, acid and alkali. If the quality of concrete is not up to standard, its mechanical properties will be reduced, affecting the stability and durability of the building structure. After the concrete is poured, samples must be taken for performance testing to avoid accidents.

[0003] However, the device currently used for sampling roads made of poured concrete has poor stability. When the cutting tool encounters resistance when drilling, the device is prone to displacement from the set position, destroying the integrity of the sample shape. Manual cleaning of the dust on the surface of the sampling area wastes working time, and there is a lack of a limiting structure when the tool moves down. Therefore, we propose a sampling device for building concrete performance detection to solve the above problems. Utility Model Content
