Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete quality detection device for engineering. Background Art

[0002] Traditional concrete quality inspection usually involves casting mold compression inspection before construction. Generally, multiple inspection intervals are drawn at intervals on the concrete component to be inspected, and a manual handheld rebound instrument needs to be fixed in this inspection interval. The arm is prone to fatigue after holding the instrument horizontally for a long time, which will change the impact force of the rebound hammer's impact rod on the casting. When using the rebound hammer for inspection, the axis of the rebound hammer needs to be perpendicular to the surface of the concrete component to be inspected in order to obtain more accurate data. After the manual handheld rebound hammer is moved to the next inspection interval, the accuracy of the data received by the rebound hammer will be reduced. In view of this, a concrete quality inspection device for engineering use is proposed. Utility Model Content
