Abstract
The utility model relates to the technical field of stress detection, and discloses a steel structure welding residual stress detection device, which is characterized in that the top of a base is fixedly provided with a bottom sheet, the two sides of the base and the bottom sheet are provided with through grooves, and the through grooves are internally provided with clamping columns in a sliding manner; stress detection on steel structures of different sizes is achieved by arranging a bottom piece, clamping columns and other structures, welded reinforcing steel bars are placed between the clamping columns, the tops of the clamping columns are inclined faces, the reinforcing steel bars are located on the tops of the clamping columns and pressed downwards, the clamping columns can slide towards the two sides after being extruded, and after the reinforcing steel bars enter the clamping columns, the clamping columns can clamp the reinforcing steel bars due to the tension of springs. The welding points are limited by the springs, and different stress data are obtained by performing stress detection on the welding points and the positions on the two sides respectively, so that the effect of facilitating detection is achieved.
