Abstract

The present invention relates to one kind of powerful buckle for prefabricated unit, prefabricated unit with the buckle and it forming process. The powerful buckle has screw thread connecting or bayonet jointing structure with steel bar hole in the center and upset steel bar head clamping stage around the steel bar hole. The prefabricated pre-stressed unit has reinforcing rib skeleton comprising longitudinal ribs and ring ribs and the each end of its longitudinal ribs are bayonet jointed to the upset steel bar head clamping stage. After the powerful buckle has the end fixed onto the fixing board and expanding board and set inside formwork, and concrete is deposited and the expanding board is drawn to set pressure, to form centrifugal pile and obtain prefabricated pre-stressed unit.
