Description

Technical Field

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

[0002] A concrete wall is a wall structure cast from a mixture of cement, sand, stones, etc. Concrete walls are commonly used in buildings for load-bearing walls, exterior walls, partition walls, etc. The characteristics of concrete walls include high strength, good waterproof performance, high temperature resistance, fireproof and heat insulation. In addition, concrete walls also have the advantages of convenient construction and good durability. In construction practice, concrete walls can be precast or cast on-site. After the concrete wall is cast, it needs to be detected with a concrete wall rebound detection device; however, when the current concrete wall rebound detection device is in use, one hand needs to hold the middle part of the rebound instrument to play a role in straightening, but it is necessary to ensure that the axis of the rebound instrument is always perpendicular to the concrete test surface. The way of holding by hand is not absolutely stable, so it is easy to cause detection errors. Moreover, it is also necessary to hold the tail of the rebound instrument with the other hand to apply pressure to the rebound instrument for detection, which is rather troublesome.
