Abstract

The utility model discloses a steel bar sleeve grouting connection joint residual deformation detection device comprising the following structures: a lower support base station provided with a plurality of positioning hole columns in a surrounding manner; the fixed cylinder plate is provided with a positioning sleeve part for guiding in the positioning hole column, and the positioning sleeve part is used for sleeving the reinforcing steel bar sleeve grouting connector; the bearing plate is provided with a through hole column penetrating through the steel bar sleeve grouting connector; and the upper pressing die base is provided with a guide column groove corresponding to the through hole column, the bottom of the guide column groove accommodates an indentation test ball, and the indentation test ball presses and covers the top of the reinforcing steel bar sleeve grouting connection joint. According to the utility model, the fixed cylinder plate and the bearing plate are matched to clamp the reinforcement sleeve grouting connector, then the reinforcement sleeve grouting connector is assembled to the lower supporting base and the upper pressing die holder, and the upper pressing die holder is hydraulically driven, so that the indentation test ball in the upper pressing die holder presses against the top of the reinforcement sleeve grouting connector to form an indentation; and finally, taking out the indentation test ball to observe the indentation stress residual deformation.
