Description

Technical Field

[0001] The invention relates to the field of detectors, in particular to a construction engineering concrete quality detector. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement concrete that is made by mixing cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion. The ultrasonic-rebound comprehensive method is usually used for non-destructive testing of concrete quality. The ultrasonic-rebound comprehensive method refers to a method of using an ultrasonic instrument and a rebound instrument to measure the sound and rebound values ​​in the same measuring area of ​​the component concrete, and then using the established strength measurement formula to deduce the concrete strength of the measuring area.

[0003] The traditional detection method requires the use of a rebound hammer and an ultrasonic instrument to detect the concrete wall at the same position respectively. Using two instruments twice cannot guarantee that the concrete wall is detected at the same position. There are slight errors in the detection position, resulting in a certain error between the detection result and the actual result. At the same time, since concrete itself is made of a mixture of sand, gravel and cement as the main materials, the surface of the concrete wall is uneven and has a large number of small protrusions. During the detection process, the rebound hammer needs to keep the axis of the rebound hammer perpendicular to the concrete wall, which will cause an error between the detection result of the rebound hammer and the actual result. At the same time, when detecting inclined concrete walls, the only way to judge whether the rebound hammer is perpendicular to the concrete wall is to rely on the naked eye or experience, resulting in inaccurate detection results.
