The invention relates to a scaffold connector for building construction, which includes two clamping component groups, a connecting component, a detachable clamping unit, and an emergency buffer ring group. The two clamping component groups are connected by a connecting component. A detachable clamping unit is provided at the right end of the clamping component group arranged on the right side, and an emergency buffer ring set is connected to the lower ends of the two clamping component groups. The present invention can solve the problem that due to the immobilization of the structure of the existing connectors, it is impossible to adjust adaptively according to the angle and position changes between the two steel pipes during use. The connecting piece forms an effective connection. When the connecting piece is tightly locked with the steel pipe in the upright state, it may be affected by gravity and show a downward trend. It is difficult for personnel to find it in time, and the personnel are still working on the scaffold platform. It is difficult to bear the gravity and slide down, which leads to localized collapse of the scaffolding and other problems.
