Beschreibung
Zusammenfassung:	The utility model discloses a civil engineering steel bar deformation measuring device which comprises a fixed annular disc and a movable annular disc, and a limiting hole is formed in the side, close to the fixed annular disc, of the movable annular disc in a penetrating mode. The stand column is arranged on the side, close to the movable annular disc, of the fixed annular disc, and the stand column penetrates out of the movable disc through the limiting hole; the fixing unit is arranged on the fixed annular disc, and at least part of the fixing unit penetrates to the inner side of the fixed annular disc; the measuring unit is arranged on the movable annular disc; and the driving unit is arranged at the bottom of the movable annular disc, and at least part of the driving unit is connected with the measuring unit. The reinforcing steel bar deformation measuring device can prevent the reinforcing steel bar from damaging the surface of the reinforcing steel bar when the reinforcing steel bar is fixed, can enabl
